DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 4 , the present utility model provides a technical solution:

[0024] A pneumatic clamping and rapid welding device includes a rapid welding mechanism 1 for enabling workers to quickly and accurately weld nuts. The rapid welding mechanism 1 includes:

[0025] A pneumatic clamping unit 11, including a cylinder 113, with a connecting rod 114 fixedly installed at the bottom end of the cylinder 113, and positioning magnets 115 fixedly installed at both ends of the connecting rod 114;

[0026] The straightening and positioning unit 12 is arranged at the bottom of the workbench 111 and is used to straighten the position of the parts.

[0027] In this embodiment, the pneumatic clamping unit 11 further includes a workbench 111. A fixing frame 112 is fixedly installed on the top of the workbench 111, and the cylinder 113 is fixedly installed at the front end of the fixing frame 112. A cylinder controller 116 is fixedly installed on the right side of the workbench 111. The cylinder controller 116 is connected to the cylinder 113 through a pipeline. Two sliding grooves 118 are opened inside the workbench 111. The pneumatic clamping unit 11 further includes a product part positioning 117 fixedly installed on the top of the workbench 111. The product part positioning 117 slides and inserts into the hole position of the part.

[0028] The nut is adsorbed by the positioning magnet 115. The user rotates the cylinder controller 116, and the cylinder 113 pushes the connecting rod 114 and the positioning magnet 115 to move downward. The positioning magnet 115 drives the nut to move downward synchronously, so that the nut fits tightly with the part, thereby enabling the worker to quickly and accurately position the part for the welding of the nut, and avoiding the welding slag from entering the nut, reducing the unnecessary work of the worker, improving the production efficiency, and thus reducing the production cost.

[0029] Rotate the cylinder controller 116, and the cylinder 113 returns. The cylinder 113 and the positioning magnet 115 are disengaged from the nut, and the part can be taken out.

[0030] In this embodiment, the straightening and positioning unit 12 includes a mounting frame 121 fixedly installed at the bottom of the workbench 111. Two straightening baffles 122 are fixedly installed at the front end of the mounting frame 121. The straightening and positioning unit 12 further includes two limiting slide rods 123 fixedly installed inside the mounting frame 121. A straightening clamping plate 124 is slidably installed on the outer circle of the limiting slide rod 123, and the straightening clamping plate 124 is slidably adapted inside the sliding groove 118. The straightening and positioning unit 12 further includes a fixing rod 128 fixedly installed on one side of the straightening clamping plate 124. A pull rod 125 is fixedly installed on the front side of the fixing rod 128. A return spring 126 is sleeved on the outer circle of the pull rod 125. The front end of the return spring 126 slidably penetrates through the front plate of the mounting frame 121 and is fixedly installed with a grip 127.

[0031] When the product part positioning 117 slides and inserts into the hole position of the part to position the part, there will be a certain gap between the product part positioning 117 and the hole position, and the part will be inclined. By the user pulling the grip 127 to drive the fixing rod 128 to move synchronously, the fixing rod 128 drives the two straightening clamping plates 124 to slide on the outer circle of the limiting slide rod 123 and inside the sliding groove 118, and squeezes the part, thereby straightening the position of the part and improving the accuracy of the welding position.

[0032] After the part is positioned, the return spring 126 pushes the fixing rod 128 by its own elastic force to reset the fixing rod 128.

[0033] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0034] During operation, first, the user connects the device to an external power supply. Then, the user positions the part by sliding the product part positioning 117 into the hole of the part. After that, the user pulls the grip 127 to drive the fixing rod 128 to move synchronously. The fixing rod 128 drives the two straightening clamping plates 124 to slide on the outer circle of the limit slide rod 123 and inside the sliding groove 118 to squeeze the part and straighten the position of the part. Then, the positioning magnet 115 adsorbs the nut. The user rotates the cylinder controller 116, and the cylinder 113 pushes the connecting rod 114 and the positioning magnet 115 to move downward. The positioning magnet 115 drives the nut to move downward synchronously, so that the nut fits tightly with the part to quickly and accurately position the part. After positioning, the return spring 126 pushes the fixing rod 128 by its own elastic force to reset the fixing rod 128. Then, after welding is completed, the user rotates the cylinder controller 116, and the cylinder 113 returns. The cylinder 113, the positioning magnet 115 and the nut are separated, and the part can be taken out.
