Embodiment 1

[0111] Such as Figures 1 to 4 As shown, the clamping device 100 provided in this embodiment is used to support a flat plate-shaped workpiece 200 to be locked, and the workpiece 200 to be locked is provided with a plurality of hole positions 201 to be locked, and each hole to be locked is The positions 201 are respectively used to assemble a to-be-locked screw rod (not shown) and a to-be-locked nut (not shown). The clamping device 100 includes a workbench 10, a locking device 20 installed on the workbench 10 and Reset device 30.

[0112] The workbench 10 is a cover plate structure, which has an inner cavity 10a opening downward. The top surface of the workbench 10 has a clamping groove 11 for placing the workpiece 200 to be locked, and the bottom surface of the clamping groove 11 has a plurality of positioning holes 12 communicating with the inner cavity 10a. The hole positions 201 correspond one-to-one. In this embodiment, the top surface of the workbench 10 has a transvers...

Embodiment 2

[0143] In the following, only the differences from the previous embodiment will be described in detail.

[0144] Such as Figure 13 As shown, the reset device 30 provided in this embodiment includes a mounting base 324 , a snap spring 325 and a pressing plate 326 . Specifically, the top surface of the mounting base 324 is provided with a mounting slot 327 penetrating through both ends of the mounting base 324 , and the mounting slot 327 has a first longitudinal wall 3271 and a second longitudinal wall 3272 opposite and parallel to each other. The snap ring 325 includes a support section 3251 flat on the bottom surface of the mounting groove 327, an elastic section 3252 extending upward from the support section 3251, and an arc curved outward from the elastic section 3252 to the second longitudinal wall 3272. Section 3253 and a contact for contacting a workpiece 200 to be locked and making the elastic section 3252 elastically deform along the direction in which the workpiece 2...

Embodiment 3

[0149] In the following, only the differences from the previous embodiment will be described in detail.

[0150] Such as Figure 15 As shown, the reset device 30 provided in this embodiment is used to reset the workpiece (not shown) upwards, and includes a fixed bracket 330 , a connecting shaft 331 , a rotating part 332 and a spring 333 . One end of the connecting shaft 331 is fixed on the fixed bracket 330 , and the rotating part 332 includes a pivot portion 3321 and a contact portion 3322 connected to each other. The pivoting portion 3321 is rotatably sleeved on the connecting shaft 331 , and the contact portion 3322 protrudes from the outside of the fixing bracket 330 for abutting against the bottom side of the workpiece. The spring 333 is respectively connected with the fixed bracket 330 and the rotating part 332, so as to pull the contact part 3322 of the rotating part 332 to rotate upward around the pivot part 3321, thereby driving the workpiece to reset and move upward...

Abstract

The invention relates to the technical field of automation equipment and provides a clamping device, an automatic screw penetrating machine and an automatic locking method. The clamping device provided by the invention is used for supporting a to-be-locked workpiece with multiple to-be-locked hole sites, and comprises a working platform with a clamping groove for holding the to-be-locked workpiece in the top surface, a locking device used for propping and pressing the to-be-locked workpiece in the clamping groove and a resetting device enabling the to-be-locked workpiece to move upward to be reset, positioning holes corresponding to the to-be-locked hole sites are formed in the bottom surface of the clamping groove, and a predetermined correction clearance is left between the side wall of the clamping groove and the periphery of the to-be-locked workpiece. Compared with the prior art, the clamping device provided by the invention has the advantages that the deviation problem of coordinates of the hole sites can be avoided, and locking precision and accuracy are improved. The automatic screw penetrating machine provided by the invention can realize quick adjustment of positions of the to-be-locked workpiece. The automatic locking method provided by the invention can improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of automation equipment, in particular to an automatic screw threading machine and an automatic locking method. Background technique [0002] Automatic screwing robots are widely used in automatic assembly lines in the electronics industry, such as: mobile phones, hard drives, keyboards, electronic toys, computers, DVDs, home appliances, plastics, electrical appliances, communication equipment, electrical appliances, toys, electronic processing, etc., or automatic assembly of automotive screws Industries, such as: motors, motors, parts, etc., are automatically screwed and assembled. [0003] At present, the existing automatic screw driving robot, in the screw locking process, the product is completely fixed, the screw cannot be locked to the corresponding hole position due to the product hole position error and the motor lost step during the operation of the screw machine, resulting in Lock payment failure ...
