Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-7, a riveting machine comprises a machine base 1, a driving box 2 is fixedly installed on the back of the top of the machine base 1, a fixing sleeve 3 is fixedly installed on the position, located on the front of the driving box 2, of the top of the machine base 1, a material box 4 is fixedly installed on the position, located on one side of the driving box 2, of the top of the driving box 2, a supporting frame 5 is fixedly installed on the top of the supporting frame 5, an upper mold cylinder 10 is fixedly installed on the top of the extending end of the supporting frame 5, an upper mold body 11 is movably installed on the bottom of the extending end of the supporting frame 5, the top of the upper mold body 11 is fixedly connected with the bottom of the upper mold cylinder 10, two material pushing chutes 6 are fixedly installed on the front of the driving box 2, a feeding device 7 is sleeved on the top of the material pushing chutes 6 in a sliding manner, the feeding device 7 comprises a sliding, an inclined conveying sliding rod 8 is fixedly installed on one side, close to the driving box 2, of the material box 4, a movable sleeve 9 is movably sleeved on an inner ring of the fixed sleeve 3, a spring 17 is fixedly connected to the bottom of the movable sleeve 9, a material pushing cylinder 13 is fixedly installed inside the driving box 2, one end of a push rod 73 is fixedly connected with the material pushing cylinder 13, a PLC (programmable logic controller) 12 is fixedly installed at a position, located on the front side of the material box 4, of the top of the base 1, a lower die seat 14 is fixedly installed at a position, located on the inner ring of the fixed sleeve 3, of the top of the base 1, a die pressing table 15 is fixedly installed at the top of the die pressing table 15, a lower die body 16 is fixedly installed at the top of the die pressing table 15, an air hole 18 is formed in the lower die body 16 in a penetrating mode, the bottom of the air.

Wherein, the spout has been seted up to fixed sleeve 3's internal surface, movable sleeve 9's surface is provided with the lug, fixed sleeve 3's spout and movable sleeve 9's lug looks adaptation, this design is in order to play spacing effect, prevent that slip from appearing in two inside and outside sleeves, the square breach has been seted up at movable sleeve 9's the back, and the width of this breach is the same with the external diameter size of rivet, the bottom of rivet can pass through movable sleeve 9 when convenient material feeding unit 7 pay-off, and then make the rivet arrive die body 16 directly over down, and the same design of size can also play the effect of inspection, just explain when the rivet is blocked by movable sleeve 9 that the diameter of rivet is not conform to the standard or movable sleeve 9's position has taken place the deviation.

The central line of the transmission slide rod 8 and the circular line of the initial position of the semicircular magnet 72 are on the same vertical plane, the width of the chute at the center of the transmission slide rod 8 is the same as the outer diameter of the rivet, the semicircular diameter of the semicircular magnet 72 is the same as the outer diameter of the rivet cap, so that the rivet can directly slide and cannot fall and be blocked when being conveyed by the transmission slide rod 8, the rivet cap is arranged on the transmission slide rod 8 and can just slide to the semicircular magnet 72 to be sucked, and the fact that the rivet is caught and corrected vertically is guaranteed.

When the feeding device 7 is located at the maximum working position, the circle center line of the semicircular magnet 72 coincides with the circle center line of the lower die body 16, and when the material pushing cylinder 13 works once, the rivet on the semicircular magnet 72 is just pushed to the position right above the lower die body 16, so that the accuracy is ensured, and the subsequent riveting is facilitated.

Wherein, lower mould 16 outer lane middle part is bellied little cambered surface, and lower mould 16 and moulding-die platform 15 junction are the arc surface, and lower mould 16 is with rivet actuation back, with the protruding department of rivet chucking under the effect of suction, guarantees that the rivet can not squint in vertical direction, and the riveting effect is better.

The magnetic force of the semicircular magnet 72 is greater than the gravity of the rivet, and the suction force of the air hole 18 on the lower die body 16 is greater than the magnetic force of the semicircular magnet 72, so that the whole conveying and positioning process of the rivet can be realized, and the rivet can not fall off or deviate halfway.

The working principle is that the PLC 12 is started to work, an object to be riveted is moved to the movable sleeve 9, the riveted part is ensured to be positioned right above the lower die body 16, the rivet is sent out by the material box 4, the rivet slides downwards on the conveying slide rod 8 under the action of gravity, when the rivet slides to the end part, the rivet cap of the rivet is just aligned to the semicircular magnet 72, the semicircular magnet 72 is tightly attracted to the rivet under the action of magnetic force and ensures that the rivet is vertical, at the moment, the material pushing cylinder 13 is controlled by the PLC 12 to push the slide block 71 to slide towards the front side, and therefore the feeding device 7 sends the rivet to the position right above the lower die body 16;

the exhaust fan 20 starts to work, rivets on the feeding device 7 are washed off by the top of the lower die body 16 through suction generated by the air pipe 19 and the air hole 18 to be sleeved on the outer ring of the lower die body 16, and the rivets are tightly clamped through protrusions on the lower die body 16 and cannot shake left and right;

the upper die body 11 is pushed downwards by the upper die cylinder 10 under the control of the PLC 12, the upper die body 11 moves downwards and is pressed on the upper surface of the rivet cap, the rivet is pressed downwards by the upper die body 11 under the action in the cylinder, the bottom of the rivet is turned around, the lower die body 16 is used for the maximum position and then is recovered, a riveted object is taken down, and riveting is completed.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
