Detailed Description

As shown in fig. 1-4, two sides of a base 1 are provided with sliding rails, sliding blocks are arranged on the sliding rails, a clamp positioning mechanism 3 is connected with the sliding blocks, and the clamp positioning mechanism 3 is used for fixing a clamp foundation 4. The fixture positioning mechanisms 3 are provided with 4, and the fixture foundation 4 is provided with a part positioning mechanism 5.

The fixture positioning mechanism 3 has the structure that two lugs in the vertical direction are arranged on a fixed block, a compression block is arranged between the two lugs, a rotating shaft 2 is arranged at one end of each lug and each compression block, and a positioning bolt 6 is arranged at the other end of each lug and each compression block.

The base 1 is provided with a plurality of locating pins I7 for locating the clamp foundation 4.

The part positioning mechanism 5 is structurally characterized in that a connecting piece 12 in the vertical direction is arranged on a bottom plate 14, and positioning blocks 11 matched with the parts in size and shape are arranged on the top surface and the side surfaces of the connecting piece 12.

The bottom plate 14 is provided with the air cylinder 13, the telescopic end of the air cylinder 13 is provided with the locating pin II10, the locating pin II10 is inserted into the part 8 to be welded, and the sensor 9 on the locating block 11 senses the part 8 to be welded, so that welding can be performed.

The use method comprises the steps of placing corresponding part positioning mechanisms 5 on a base 1 aiming at parts 8 to be welded, sliding the clamp positioning mechanisms 3, enabling the clamp positioning mechanisms 3 to contact the part positioning mechanisms 5, starting the clamp positioning mechanisms 3, enabling the compression blocks to compress the clamp foundation 4, and fixing the compression blocks by using positioning bolts 6. The part 8 is placed on the connecting piece 12, the part 8 is fixed by the positioning blocks 11 at the top end and the side face, and the cylinder 13 drives the positioning pin II10 to pass through the positioning pin hole on the part 8 for further positioning. After which the next step is performed.

The part positioning mechanism 5 is fixed on the base 1 through the fixture positioning mechanism 3, so that the positioning of the part positioning mechanism 5 is ensured, the part positioning mechanism 5 can be quickly separated from the base 1, and other part positioning mechanisms 5 are replaced. The quick positioning and the quick installation can be realized. Solves the problems that the welding of multiple products can not be switched rapidly and the manufacturing cost of the clamp workstation is high. When a new product is switched, the whole set of mechanism is replaced, and the mechanism can be compatible with various part sizes, so that the debugging difficulty is greatly reduced, and the time is saved.

What has been described above is merely a preferred embodiment of the present utility model. It should be noted that variations and modifications can be made by those skilled in the art without departing from the principles of the present utility model, and should also be considered as falling within the scope of the present utility model.
