Technical Field

The invention relates to the technical field of assembly equipment, in particular to a tool.

Background

It is known that a brake disc is assembled by a disc body and a hub body, and the assembly of the disc body and the hub body is realized by a circle of bolts penetrating through the disc body and the hub body.

It will be readily appreciated that to achieve a turn of bolts passing through both the disc and the hub, the bolts need to be arranged by means of tooling. Specifically, a circle of sunk grooves are formed in the upper end face of the tool, and bolt caps of all bolts are placed in the sunk grooves manually or by equipment so that all the bolts can be inverted. In order to make the bolt cap stretch into the counter bore smoothly, among the prior art, the size setting of the aperture (or the cross section) with the counter bore is far greater than the bolt cap to make the bolt cap can be more smoothly arrange in the counter bore in order to improve the efficiency of arranging the bolt (if make the size of counter bore set to the size that strictly matches with the bolt cap, no matter utilize jacking equipment or manual work to control the bolt, all be difficult to the accurate heavy groove of inserting of bolt cap, and, when utilizing jacking equipment to insert the in-process in heavy groove with the bolt cap, probably because of bolt and heavy groove can not strictly aim at, and make the bolt cap and the terminal surface outside the heavy groove take place to interfere and form the impact, and then lead to bolt and frock to damage).

However, although the counter bore with the larger size can facilitate the bolt cap to be placed in the counter bore, the probability of inclination of the bolts in the arrangement process is increased, the probability of inclination of each circle of bolts is higher due to the fact that the bolts need to be arranged in an excessive number, and the assembly of the disc body and the hub body cannot be achieved due to the fact that one bolt in one circle of bolts is inclined, at the moment, the inclined bolts need to be checked by personnel and righted manually subsequently, and therefore the assembly efficiency is reduced.

In addition, the accuracy of the positioning of the bolts by the counterbores with large dimensions results in a ring of bolts not being uniformly arranged, and further results in the bolts not passing through the disc and the hub body simultaneously.

To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the invention have been omitted.

As shown in fig. 1 to 9, the embodiment of the present invention discloses a tool for arranging a bolt 100, and in particular, the tool is used for arranging the bolt 100 upside down by one turn and for centering the bolt 100. This frock includes: a lower tray 10, an upper tray 20, a centering mechanism 40, and a drive member 50. Wherein, a circle of counter bores corresponding to the bolts 100 to be arranged are arranged on the upper disc surface of the lower disc body 10. The upper tray 20 is positioned above the lower tray 10. The righting mechanism 40 includes a plurality of counterbores in a one-to-one correspondence, as shown in fig. 5, and each of the righting mechanisms 40 includes: a retaining post 41, a righting flap 421, a first resilient member 43. The lower end of the retaining column 41 extends into the counter bore, and the upper end surface of the retaining column 41 is provided with a shrinkage cavity 411 downwards, wherein the shrinkage cavity 411 is a taper hole. The two righting petals 421 include two, the upper end of the righting petal 421 is provided with a half groove, the two righting petals 421 are buckled to form a righting body 42, so that the upper end of the righting body 42 forms a sinking groove 422 matched with the nut shape of the bolt 100; the outer circumference of the righting body 42 forms a conical shaft 423 matching with the shrinkage cavity 411. First elastic component 43 sets up between two petals 421 of righting, chooses for use the spring as first elastic component 43, and at this moment, set up a blind hole on at least one relative surface of the petal 421 of righting for the spring sets up in the blind hole, and the both ends of spring are respectively through leaning on two petals 421 of righting and exert the counter-force that makes both keep away from mutually to the petal 421 of righting, and the effect of this blind hole lies in: when the two centering flaps 421 are close to each other, the spring does not interfere with the centering flaps 421. As shown in fig. 4, the driving part 50 serves to drive the upper tray 20 to move vertically. In the present invention, the upper plate body 20 is configured to be interlocked with the righting body 42. This is so: when the driving part 50 drives the upper tray body 20 to drive the righting body 42 to move downwards, the shrinkage hole 411 forces the two righting petals 421 to approach, so that the sinking groove 422 covers the nut to right the bolt 100.

The working principle of the tool is described as follows:

as shown in fig. 8 in combination with fig. 1, the upper disc body 20 is driven by the driving part 50 to make the upper disc body 20 in the high position, and simultaneously, the righting body 42 linked with the upper disc body 20 is also in the high position, and under the action of the spring, the two righting petals 421 are in a state of being away from each other, so that the sunken groove 422 at the upper end of the righting body 42 is in a maximum size state, and at this time, the bolt 100 is placed into the sunken groove 422 by a person or an apparatus (the nut of the bolt 100 is placed into the sunken groove 422) until a circle of the bolt 100 is arranged.

After the arrangement of the bolts 100 is completed, the upper disc body 20 is driven by the driving part 50 to move the upper disc body 20 downwards, and simultaneously, the righting body 42 linked with the upper disc body 20 also moves downwards, so that the conical shaft 423 of the righting body 42 moves downwards, at this time, as shown in fig. 9, the hole wall of the shrinkage cavity 411 presses the conical shaft 423 in a split state to enable the two righting petals 421 to approach, and simultaneously, the sinking groove 422 at the upper end of the righting body 42 contracts due to the approach of the two righting petals 421, so that the bolts 100 which are inclined in one circle of the bolts 100 can be righted, and meanwhile, the bolts 100 which are unevenly arranged due to the large size of the sinking groove 422 are rectified, so that the bolts 100 are evenly arranged.

According to the invention, by arranging the righting mechanism 40, the bolts 100 are righted and uniformly distributed by one-time downward movement of the upper tray body 20.

In a preferred embodiment of the present invention, as shown in fig. 5 and 6, the upper disc body 20 is provided with through holes corresponding to the counter bores one by one, the upper ends of the retaining columns 41 extend into the through holes, and the centralizing bodies 42 are located in the through holes; wherein: an upward step surface 424 is formed at the upper part of the righting body 42, a downward step surface 21 is formed at the through hole, and the upper disc body 20 pushes against the step surface of the righting body 42 by the step surface of the through hole to drive the righting body 42 to move downwards. In this embodiment, the step surfaces are provided on the through hole of the upper tray body 20 and the centering body 42, so that the downward movement of the centering body 42 is synchronized with the downward movement of the upper tray body 20, and the design is ingenious.

In a preferred embodiment of the present invention, the righting mechanism 40 further comprises: and a second resilient member 46, the second resilient member 46 being disposed within the counterbore and between the bottom of the counterbore and the retaining post 41. Preferably, an elastic pad is selected as the second elastic member 46.

The reason and effect of the second elastic member 46 will be described below.

The second elastic member 46 is provided based on a possible error in the radial dimension of the nut of the bolt 100. Specifically, in one circle of bolts 100, when the nuts of some of the bolts 100 are larger and the nuts of other bolts 100 are smaller, after the upper disc body 20 moves down the centering flaps 421, the larger-sized nut is firstly centered and clamped by the groove walls of the sunken grooves 422, and at this time, the smaller-sized nut is not centered because of not contacting with the sunken grooves 422 (all the sunken grooves 422 are the same in size), if the lower end of the holding column 41 is in direct or indirect rigid contact with the groove bottom of the sunken grooves 422, the larger-sized nut generates a reaction force to the two centering flaps 421 due to the compression of the larger-sized nut, and the reaction force is transmitted to the upper disc body 20 through the matching of the conical shaft 423 and the conical hole, so that the upper disc body 20 generates a larger resistance force. This results in: if the driving member 50 continues to drive the upper tray 20 downward, the larger sized nut and its corresponding sink 422 may be deformed and damaged by the pressing; if the driving member 50 stops driving the upper tray 20 to move down, the bolt 100 corresponding to the smaller sized nut cannot be centered.

In the present embodiment, the second elastic member 46 functions to: while the upper plate 20 carries the righting body 42 downwards, the second elastic element 46 provides an upward counter force to the retaining column 41 due to the accumulated elastic potential energy, so that: when the larger size nut is centered, the retaining column 41 corresponding to the smaller size nut moves upward due to the upward opposing force of the second elastic body to force the corresponding centering flap 421 to further approach and center the bolt 100 corresponding to the smaller size nut. In short, the second elastic body enables the conical shaft 423 of the righting body 42 corresponding to the nut with the smaller size to extend into the shrinkage cavity 411 to a depth greater than that of the nut with the larger size, so that all the bolts 100 with the size error can be righted at the same time.

In a preferred embodiment of the present invention, as shown in fig. 5 and 6, the righting mechanism 40 further comprises: and a sheath 44, wherein the sheath 44 is sleeved outside the retaining column 41. Preferably, the retaining post 41 is a stepped cylinder; the lower end of the sheath 44 abuts on the step surface of the step column, and the upper end of the sheath 44 is higher than the upper end of the holding column 41. In this embodiment, the sheath 44 functions to: at least to increase the strength of the retaining post 41.

In a preferred embodiment of the present invention, as shown in fig. 7 in combination with fig. 1 and 2, the sheath 44 is formed with a locking groove 441 at its outer periphery; the tool for arranging the bolts 100 further comprises a ring body 30; the ring body 30 is arranged between the upper disc body 20 and the lower disc body 10 and fixed with the lower disc body 10, the sheath 44 penetrates through the ring body 30, and the ring body 30 limits the sheath 44 and the retaining column 41 to be separated from the counter bore through the clamping groove 441.

In a preferred embodiment of the present invention, as shown in fig. 5 and 6, the upper portion of the sheath 44 is sleeved with a stopper sleeve 45; a stop ring 47 is arranged at the through hole at the lower end of the stop sleeve 45, and the upper end of the stop sleeve 45 faces a downward step surface formed on the righting body 42; when the driving part 50 drives the upper tray 20 to move upward, the stopping sleeve 45 pushes the righting body 42 to move upward along with the upward movement of the upper tray 20. In this embodiment, the centralizing body 42 can move up synchronously with the upper disc body 20 by the cooperation of the stop sleeve 45 and the stop ring 47.

In a preferred embodiment of the present invention, as shown in fig. 4, the driving part 50 is a cylinder disposed below the lower plate 10, and a piston rod 51 of the cylinder penetrates the lower plate 10 and is connected to the middle of the upper plate 20. The piston rod 51 of the air cylinder is extended and contracted by starting to drive the upper disc body 20 to move vertically.

In a preferred embodiment of the present invention, as shown in fig. 5, the outer circumference of the middle portion of the sheath 44 is formed with a stepped surface, and the lower end surface of the stopper sleeve 45 has a certain distance from the stepped surface formed by the outer circumference of the middle portion of the sheath 44. In the present embodiment, the certain distance is used to define the moving stroke of the righting body 42, and the driving stroke of the driving member 50 is set according to the certain distance.

In addition, the cross section of the sink groove 422 is set based on the cross section of the nut of the bolt 100, and when the cross section of the nut is circular, the sink groove 422 is set to the sink groove 422 having a circular cross section; when the nut has a hexagonal cross-section, the sink 422 is configured to have a hexagonal cross-section.
