Specific embodiment

To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing Step ground detailed description.Only this is stated, the present invention occurs in the text or will occur up, down, left, right, before and after, it is inside and outside etc. just Position word is not to specific restriction of the invention only on the basis of attached drawing of the invention.

Referring to Fig. 2, the present invention discloses a kind of impeller head, including the shell with feeding-passage 100 and is arranged described Ball blast disk 1 in shell (attached drawing does not show overall structure), the feeding-passage 100 can be and the integrally formed knot of shell Structure is also possible to additionally mounted individual structure on the shell.Wherein, it is (attached to be connected with rotary drive mechanism for the ball blast disk 1 Figure is not shown), drive ball blast disk 1 to rotate by rotary drive mechanism, the rotary drive mechanism can use individual motor, It can also be using structures such as motor-driven gear transmission, V belt translations.

Multiple areas Fen Wan 31 of the output shaft circle distribution around the rotary drive mechanism are provided on the ball blast disk 1, It is lattice 3 between the adjacent area Fen Wan 31, the inner end of the lattice 3 surrounds abrasive material storehouse 32, and the abrasive material storehouse 32 is connected to The feeding-passage 100 and the area Fen Wan 31, the outer end of the lattice 3 are with the guard mechanism 2 for closing the area Fen Wan outer end, The guard mechanism 2 has one section of notch 20 that abrasive material is cast out for the area Fen Wan 31.Work is processed using impeller head of the invention When part surface, in the abrasive material storehouse 32 by 100 conveying grinding material of feeding-passage to impeller head, the abrasive material in abrasive material storehouse 32 is made in gravity It is fallen under in multiple areas Fen Wan 31, different 31 Concentric rotations of the area Fen Wan make abrasive material centrifugation to the outermost end and quilt in the area Fen Wan Guard mechanism stops, and when the area Fen Wan is rotated to notch, the abrasive material in the area Fen Wan is spilled over.

Ball blast disk 1 of the present invention can use following three kinds of embodiments:

The first embodiment, the ball blast disk 1 are an integral molding structure；A ball blast disk 1 generally disk, it is described The area Fen Wan 31 and abrasive material storehouse 32 can be obtained by machining, and a side opening in abrasive material storehouse 32 is opening of being connected to feeding-passage Mouthful.The ball blast disk 1 that attached drawing 16 is shown is the structure of embodiment thus.

Second of embodiment, the ball blast disk 1 include two side cover wheels and multiple lattices, and multiple lattices are mounted on Between two ball blast disks, i.e., multiple lattices are connected into a disk-shaped structure by two side cover wheels, point between lattice It is closed by the lid wheel of two sides in ball area.The lattice can be fixedly connected by fastener with the side cover wheel of two sides.At this point, point It is individual part every portion, relatively easily processes, but installation process is complex with respect to embodiment.

The third embodiment, the ball blast disk 1 include a side cover wheel 11 and an integrally formed separation wheel 12, institute Stating separation wheel 12 includes side cover portion 121 and multiple lattices 3 set on 121 side of side cover portion, 11 Gai Hean of side cover wheel Mounted in the other side of lattice 3.Separation wheel 12 in this embodiment can be directly used mold molding and obtain, relative to implementation The area machining Fen Wan and abrasive material storehouse in mode one, high in machining efficiency, and the list in opposite embodiment two of present embodiment A lattice installation, present embodiment only need to install side cover wheel and separate wheel, and it is also comparatively convenient to install.17 He of attached drawing The ball blast disk 1 that attached drawing 18 is shown is the structure of embodiment thus.

Wherein, the area Fen Wan 31 is straight trough hole, circular hole or elliptical aperture.

As shown in Fig. 2, the direction of abrasive material abjection impeller head can be divided into the centrifugal direction V far from ball blast disc spins center_r With accelerated butt to V_t, the projectile direction of impeller head is the conjunction directional velocity of the two speed.

The exit direction of impeller head in the prior art is analyzed by Fig. 1, abrasive material slides on blade or be rolled to blade End is until leave blade, it can be seen that all abrasive materials have all reached the linear velocity of blade end, i.e., the butts of all abrasive materials to V_tIt is considered as equal, but dispersed arrangement, the abrasive material of different location arrive again since abrasive material is flown on blade from shot wheel Centrifugal direction V when up to blade end_rAnd it is unequal；The angle that blade turns over when deviating from along with abrasive material from blade end is not Unanimously, two reasons cause impeller head in the prior art to cast region broad jointly.In addition, when tuning up impeller head revolving speed, Impeller head revolving speed is bigger, abrasive material centrifugal direction V_rIt is bigger, therefore the direction for closing speed tunes up impeller head and turns further away from impeller head It needs to readjust fixture when fast so that workpiece, which is located at, casts the maximum region of density.

The exit direction for analyzing impeller head of the invention from Fig. 2 again is equally that abrasive material is slided or is rolled on lattice 3 Until leaving blade, all abrasive materials have all reached the linear velocity of 3 end of lattice, the butt of all abrasive materials for the end of lattice 3 To V_tBe considered as it is equal, in the case where only a small amount of abrasive material, abrasive material all the area Fen Wan 31 end aggregation and quilt Guard mechanism 2 blocks, centrifugal direction V_rIt is zero, when the area Fen Wan 31 enters the notch of guard mechanism 2, abrasive material is just released winged Out, centrifugal direction V_rVery little is similar to zero, and the direction of nearly all abrasive material is all consistent, only has a large amount of mills in the area Fen Wan 31 When material, come 3 end of lattice abrasive material fly out after, subsequent abrasive material just have position reach lattice 3 end, in this way these Subsequent abrasive material centrifugal direction V_rIt cannot regard zero as, this, which is just formd, casts region A, and otherwise the outgoing of abrasive material is exactly one Line, it is seen that impeller head of the invention casts line and concentrates very much；Along with all abrasive materials be all guard mechanism 2 notch it is rigid The position of beginning is detached from lattice 3, and the angle that lattice 3 turns over is certain, ensure that butt to V_tDirection is almost consistent.Another party Face, due to there is guard mechanism 2 to block, abrasive material comes the end of lattice 3 in advance already, and the revolving speed for no matter being transferred to impeller head is more Fastly, centrifugal direction V when abrasive material projects (when 31 abrasive material of the area Fen Wan is few)_rAll it is approximately equal to zero, i.e., is cast under impeller head different capacity Range is all almost consistent, without adjusting the position for workpieces processing.

Referring to attached drawing 3 to attached drawing 12, it is shown that the impeller head of numerous embodiments of the present invention.

Wherein, guard mechanism 2 of the invention can use following two structure.

The structure of the first guard mechanism, the guard mechanism are the fixed ring of a c-type, and the both ends of c-type form notch, The relatively described shell fixed setting of the fixed ring.At this point, guard mechanism 2 and ground are opposing stationary, in other words with work to be processed Part is opposing stationary.This is relatively simple for structure, easy to manufacture.

But there is a problem of when using the structure of the first guard mechanism identical as with impeller head in the prior art: Impeller head in the prior art can only use rigid abrasive, cannot use elastic grinding material.Elastic grinding material is easier to be squeezed deformation, When using impeller head in the prior art, it is easy to the extrusion in the relative motion of shot wheel and guide sleeve and enter In gap, and because of the abrasive grain for grinding and polishing demand usually in 0.3-2.0mm, lesser abrasive grain itself is easy to fall into Enter into gap to participate in squeeze, for soft elastic grinding material during the extrusion friction in gap, the heat of generation can destroy elasticity The structure of abrasive material makes its fragmentation or particle mutually be fused and is bonded in the surface of shot wheel and guide sleeve, seriously will appear stuck The problem of, prevent process from continuing.It also can there is a situation where similar between the fixed ring of c-type and shot wheel 3 in Fig. 2.To understand Certainly this problem, the present invention propose the structure of following second of guard mechanism.

The structure of second of guard mechanism, this guard mechanism are blocked by belt realization.Specifically, the guard mechanism 2 Multiple guide wheels 21 including belt 22 and for being oriented to belt 22, two of them guide wheel 21 is the both ends of notch 20, described Belt 22 is close to the outer end of lattice 3 and closes the area Fen Wan between the two neighboring lattice 3 being close to belt, lattice When 3 rotation, the belt is actively or passively operated synchronously with lattice.Specifically, one of guide wheel 21 can the company of transmission It is connected to motor or rotary drive mechanism is connected to by transmission mechanism, 22 active movement of belt is made to keep up with 3 end of lattice Linear velocity；The friction between lattice 3 and belt 22 can also be increased, all guide wheels 21 without driving, are driven by lattice 3 Belt 22 operates synchronously.

When using above-mentioned second of guard mechanism, since the part of belt 22 and the contact of lattice 3 is always relative to separation Portion 3 is static, therefore abrasive material cannot be introduced between belt 22 and lattice 3, has well solved impeller head in the prior art not The problem of elastic grinding material can be used.

As the specific embodiment of above-mentioned second of guard mechanism, the belt can be set to c-type and return ring structures, Other irregular structures can also be used.

As shown in Fig. 3, belt disclosed in Fig. 3 returns ring structures at c-type.Specifically, multiple guide wheels 21 are along lattice 3 Periphery successively arrange, the belt is wound on outside guide wheel 21 at c-type winding formula, the outer end of the lattice 3 and c-type winding formula skin Inner ring with 22 is close to, and the both ends of c-type form notch 20.In order to guarantee fitting closely for belt and lattice 3, this structure needs Using more guide wheel.

Such as attached drawing 4 to Figure 12, multiple guide wheels include two the first guide wheels 211 and 2-4 the second guide wheels 212, and two first Guide wheel 211 be guard mechanism notch 20 both ends, the belt 22 along one of them first guide wheel, 3 outer end of lattice, another First guide wheel and 2-4 the second guide wheel successively windings, second guide wheel is from lattice so that belt supports equipped with a certain distance from It opens.The quantity of guide wheel can be reduced using the impeller head of this structure, position may not necessarily be strapped near shot wheel, in skin In the case of band tensioning, the effect for reducing gap equally can achieve.

When using above-mentioned second of guard mechanism, positioned at the guide wheel of notch upper end and/or lower end be located at notch upper end with/ Or the guide wheel of lower end is respectively connected with one for adjusting the regulating mechanism of idler positions.Positioned at the idler positions of notch upper and lower ends Adjustment can change belt and horizontal angle, the variation of the belt angle of notch upper end can change the outgoing side of bullet To, if the projectile region of attached drawing 4 and attached drawing 5 compare, and the variation of the belt angle of whose lower end can effectively prevent abrasive material from The area Fen Wan of lattice lower right side slides, for example, attached drawing 5, the lower right corner Fig. 6 and Fig. 8 belt tilt angle comparison.

Guide wheel of the invention can be adjusted by installing the position of other brackets, and bracket uses screw locking, needs When adjusting the position of guide wheel or so or more, it is only necessary to change the position of bracket.Guide wheel of the invention can also use Regulating mechanism set in addition is adjusted, and as shown in Fig. 7, regulating mechanism can specifically include lower regulating mechanism 6 and upper adjusting Mechanism 7, upper regulating mechanism 7 adjust the guide wheel of notch upper end, are equivalent to the outgoing opportunity for adjusting abrasive material, it can adjust abrasive material Exit direction；Lower regulating mechanism 6 is used to adjust the number for adjusting the notch exposure area Fen Wan 31, lifting as the lower right corner Fig. 7 (shown in it is square Position) guide wheel height, be lifted belt 22 and lattice 3 tangency location, can effectively prevent elastic grinding material from lattice bottom right The area Ce Fenwan slides, and has been introduced into point situation in ball region for bullet before pills dispensing apparatus rotation, abrasive material can be prevented sliding Fall on belt and be rolled in subsequent rotation process, before this problem occurs mainly in booting, when impeller head run well, It only by acceleration of gravity is had little time from the lower right corner before the abrasive material in abrasive material storehouse 32 is not centrifuged after the enough height of the revolving speed of ball blast disk 1 It drops out.Regulating mechanism can be cylinder, be also possible to the screw rod manually adjusted.By taking screw rod as an example, one end of screw rod is bearing, It rotates and connects with the shaft of guide wheel, the other end is twisted for manpower outside the shell of impeller head and adjusted.

Referring to Fig. 2 to Figure 12, the area Fen Wan 31 is preferably provided with 4-30.In more than 31 mill of this section area Nei Fenwan Material outgoing is more coherent, and projectile range is more concentrated if analyzing the abrasive material in each area Fen Wan 31 above seldom, still, if point The abrasive material that ball area excessively then will lead in abrasive material storehouse 32 has little time very few well into the area Fen Wan 31 and 31 material stock of the area Fen Wan, reaches Less than the effect of polishing.Wherein, attached drawing 2 is to attached drawing 8 using 8 areas Ge Fenwan, and attached drawing 9 is using 14 areas Ge Fenwan, figure 11 and Figure 12 is using 11 areas Ge Fenwan, and Figure 10 is using 20 areas Ge Fenwan.

Referring to attached drawing 10 to 12, the area Fen Wan 31 of the present invention can be used with flowering structure.

The first divides ball plot structure: the area Fen Wan 31 is along the diametrical direction of ball blast disk 1 to external radiation.The area Ji Fenwan 31 Length direction center line it is identical as the diametrical direction of ball blast disk.The area Fen Wan 31 of this structure is straight trough type.This structure is convenient Use the processing of drill bit, milling cutter, lathe tool.

Second point of ball plot structure: the area Fen Wan 31 and the diametrical direction biasing of ball blast disk 1 form an angle, Duo Gesuo The biased direction in the area Shu Fenwan 31 is identical.The inner end that can be understood as the area Fen Wan is constant, the outer end in the area Fen Wan along clockwise or Person circumferentially deflects certain position counterclockwise, at this point, the diameter side of the center line of the length direction in the area Fen Wan 31 and ball blast disk To forming an angle.It is specifically as follows right-hand offset type or left eccentrically arranged type, attached drawing 11 is that the area Fen Wan is right-hand offset type, at this point, energy The projectile region entirety for casting out the projectile region cast out relative to the area straight trough Xing Fenwan is moved toward the direction far from impeller head It is dynamic.Attached drawing 12 is that the area Fen Wan is left eccentrically arranged type, at this point, the projectile region cast out can be made to cast out relative to the area straight trough Xing Fenwan Projectile region entirety it is mobile toward the direction close to impeller head.The area Fen Wan bias mode can further change the first of ball blast discharging Beginning direction and unloading position.Schematic diagram when attached drawing 13 is area Fen Wan or so biasing.

Referring to attached drawing 14 and attached drawing 15, impeller head of the invention further includes humidifier 8, the humidifier 8 be used for The abrasive material that lattice 3 is cast out is humidified.In addition, impeller head of the invention further includes the guide along the setting of abrasive material projection direction Slot 9, the deflector chute 9 spray to deflector chute 9 for material is humidified for collecting the abrasive material at least partly scattered, the humidifier 8 It is interior, and the lower section of deflector chute 9 is provided with recyclable device 10.

As being directed to the abrasive material of special requirement or there are the application enhancements of mirror finish demand, increase a kind of online humidifier 8, the humidification entrance on the top by the way that deflector chute 9 is arranged in is sprayed into or is blown into or is pressed into deflector chute 9, the increased humidification Device 8 is used for throwing the abrasive surface jet of humidified dished out of wheel or lubricator substance, in the humidification greasing substance and abrasive material Adhesive merges to form elastic material and then change the coefficient of friction of abrasive surface or directly affect coefficient of friction, throws to improve The effect of light, the elastic material of formation help to form one layer of new elastic layer in the abrasive surface passed through from this, and reason exists In, after leaving unused or be used for multiple times for a long time, the elastic layer on soft elastic grinding material surface can be removed or consume or air-dry and follow the string, And then reduce the mirror effect of polishing.Specifically, the humidification substance can for water, the mixture of water and oil, acetic acid, glycerol, Either acetic acid and the mixture of glycerol etc. have the function of that the substance of surface lubrication or surface wettability function, wet substance pass through mist The form for changing particle enters deflector chute 9, and the mode of atomization, which can be, generates micron order by the atomizer containing ultrasonic oscillator Atomizing particle, or highly pressurised liquid+atomizer or compressed air+height pressure pipe+atomizer are directly generated using water pump The modes such as collective effect are completed.Humidification amount can be adjusted according to factors such as process requirements, materials variance, loads, be adjusted Whole range is between 10ml/ (* kilograms of hour) -2000ml/ (* kilograms of hour).For the extra wet substance not being consumed It is collected by the water return outlet of 9 bottom of deflector chute.

Correspondingly, the invention also discloses a kind of shot blasting methods of application impeller head of the present invention comprising:

S1, by the abrasive material storehouse of feeding-passage conveying grinding material to impeller head.

Abrasive material in S2, abrasive material storehouse is fallen under the effect of gravity in multiple areas Fen Wan.

S3, the difference area Fen Wan Concentric rotation make abrasive material outermost end of the centrifugation to the area Fen Wan and the means block that is blocked, when point When ball area is rotated to notch, the abrasive material in the area Fen Wan is spilled over.

The present invention is realized by lattice divides ball and acceleration to cast in abrasive material, can be regarded as ball blast in the prior art The shot wheel of machine, which lengthens, replaces blade, divides ball function and the acceleration function of blade to merge shot wheel in the prior art, abrasive material The process of dispersed arrangement again is flown on blade without from shot wheel, but the area Fen Wan is deviate from the state of high concentration；And Abrasive material is when the area Fen Wan reaches guard mechanism notch, due to losing the blocking of guard mechanism, effect of the bullet in centrifugal force suddenly Under, shot wheel is flown away from, is flown along the conjunction directional velocity of centrifugal speed and tangential velocity, in the initial phase for being detached from guard mechanism Centrifugal speed is similar to zero, so the speed of outgoing is approximately equal to the direction of tangential velocity, so that the projectile region of the impeller head It concentrates very much, is very suitable for small workpiece and privileged site processing, the waste of abrasive material can be greatly decreased.

The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as Protection scope of the present invention.
