Detailed Embodiment

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. 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.

[0019] As Figures 1 to 5 shown, the present utility model is a spot welding tooling fixture 200 for automotive sheet metal 100, including a base 1 and at least one driving device 3.

[0020] The base 1 includes a fixed seat 11 and at least one movable seat 12. Preferably, the number of the movable seats 12 is 2, and the two movable seats 12 are respectively arranged at both ends of the fixed seat 11. A guiding shaft 2 is arranged between the bottom walls of the fixed seat 11 and the movable seat 12. The number of the guiding shafts 2 is 4, which are respectively distributed between the fixed seat 11 and the movable seat 12. One end of the guiding shaft 2 is fixed in the fixed seat 11, and the other end is movably sleeved with the movable seat 12. A return spring 21 is sleeved on the guiding shaft 2, and the return spring 21 abuts between the movable seat 12 and the fixed seat 11. When the two movable seats 12 and the fixed seat 11 are combined, a groove 13 adapted to the shape of the sheet metal is formed. The groove 13 can be used to accommodate the sheet metal 100, and a plurality of spot welding openings 14 are arranged on the side wall of the base 1. The spot welding openings 14 respectively correspond to the welding points of the sheet metal. A spot welder (not shown) can spot-weld the sheet metal 100 through the spot welding openings 14, and can perform simultaneous spot welding according to the number of the welding points of the sheet metal 100, so as to improve the working efficiency. A plurality of positioning columns 111 protrude from the bottom wall of the fixed seat 11, and the positioning holes on the sheet metal 100 can be sleeved on the positioning columns 111 to position the sheet metal 100. Two fixing blocks 121 are arranged on the side wall of the movable seat 12. When the movable seat 12 and the fixed seat 11 are combined, the fixing blocks 121 can fix the edge of the sheet metal in the groove 13 to prevent the sheet metal 100 from loosening during spot welding.

[0021] Preferably, two through holes 122 are formed in the bottom wall of the movable seat 12. A limiting step 1221 is arranged in the through hole 122. The other end of the guiding shaft 2 is arranged in the through hole 1112 and is sleeved with a limiting sleeve 22. The limiting sleeve 22 is limited in the through hole 122 by the limiting step 1221. The return spring 21 abuts between the limiting sleeve 22 and the side wall of the fixed seat 11. Preferably, the number of the driving devices 3 corresponds to the number of the two movable seats 12. The two driving devices 3 are respectively arranged on both sides of the movable seat 12. The driving device 3 is a cylinder. The output end 31 of the cylinder is fixedly connected with the outer side wall of the movable seat 12 and is respectively used to drive the two movable seats 12 to move along the guiding shaft 2 towards the fixed seat 11 so that the movable seat 12 and the fixed seat 11 are combined.

[0022] Working principle: The elastic force of the reset spring 21 causes the moving seat 12 to move along both ends of the guiding shaft 2. At this time, the moving seat 12 is separated from the fixed seat 11. The staff or the robotic arm sleuths the positioning hole of the sheet metal 100 on the positioning post 111 of the fixed seat 11 to position the sheet metal 100. Then, the driving device 3 simultaneously drives the moving seat to move along the guiding shaft 2 towards the fixed seat 11. At this time, the limiting sleeve 22 is moved towards the fixed seat 11 through the limiting step 1221, compressing the reset spring 21, and merging the moving seat 12 and the fixed seat 11. At this time, the fixing block 121 on the side wall of the moving seat 12 can fix the edge of the sheet metal 100 in the groove 13 to fix the sheet metal 100, preventing the sheet metal 100 from loosening during spot welding. After fixing the sheet metal, the spot welding head of the spot welder enters from the spot welding opening 14 of the base 1 to perform spot welding on the sheet metal 100. After the spot welding is completed, the output end 31 of the driving device 3 contracts, and the reset spring 21 resets, causing the moving seat 12 to move away from the fixed seat along the guiding shaft 2. The staff or the robotic arm takes out the sheet metal 100 from the base and places the next sheet metal 100. This process repeats continuously.

[0023] The advantages of the present utility model are as follows: By providing a groove 13 on the base 1, it can be used to place the automotive sheet metal 100; by providing a positioning post 111 inside the fixed seat 1, the sheet metal 100 can be sleeved into the positioning post 111 for precise positioning; by providing a fixing block 121 on the side wall of the moving seat 12, it can be used to fix the sheet metal 100 in the groove 13; by providing a guiding shaft 2, it is convenient for the moving seat 12 to reciprocate along the guiding shaft 2; by providing a reset spring 21, it is convenient for the moving seat 12 to reset; by providing a driving device 3, it can be used to drive the moving seat 12 to move towards the fixed seat 11. The present utility model provides an automotive sheet metal spot welding tooling fixture with a simple structure and convenient operation, which can be used to accurately position workpieces, facilitate the precise spot welding of workpieces by the spot welder, and improve the spot welding quality and work efficiency.

[0024] Although the specific embodiments of the present utility model have been described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative only and not used to limit the scope of the present utility model. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present utility model should all be covered by the scope protected by the claims of the present utility model.
