Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of adjustable fixture for welding relay mounting lug outer cover assembly, belong to mechanical processing fixture technical field. BACKGROUND

[0002] The existing relay production and processing with mounting lug outer cover assembly model is numerous, more than 20 kinds in total, the mounting lug welding position of each outer cover assembly is different, the fixture of using welding mounting lug is special, cannot be universal, and the outer cover assembly of welding different model needs to switch different fixture, welding efficiency is low, and the cost of design and manufacture is high, the fixture of existing welding mounting lug as shown in the figure. Figure 1 SUMMARY

[0003] The utility model solves the technical problem that the fixture of welding mounting lug in prior art is special, cannot be universal, thereby making welding efficiency low, and the cost of design and manufacture is high.

[0004] In order to solve the above technical problem, the utility model adopts the following technical scheme:

[0005] A kind of adjustable fixture for welding relay mounting lug outer cover assembly, including mounting plate, outer cover positioning block, mounting lug positioning block, stop block, adjusting screw and big screw;

[0006] One screw hole is set between the two adjusting grooves in the upper portion, and a big screw is arranged in the screw hole;

[0007] The other side of the mounting plate is provided with upper and lower T-shaped sliding grooves;

[0008] The outer cover positioning block is two, and is separately arranged in the lower T-shaped sliding groove; one end of the outer cover positioning block is connected with the adjusting screw;

[0009] The mounting lug positioning block is two, and is separately arranged in the upper T-shaped sliding groove; one end of the mounting lug positioning block is connected with the adjusting screw;

[0010] The stop block is arranged between the two mounting lug positioning blocks, and is fixedly connected with the big screw.

[0011] The beneficial effects of the above technical scheme are:

[0012] The utility model has the advantages of universality and adjustability, is flexible and variable, can effectively clamp various sizes of outer cover and mounting lug, and can adjust the welding height size of mounting lug, realizes one clamp multiple use, improves production efficiency, significantly reduces the demand for the types and quantities of fixtures, saves design and manufacturing cost.

[0019] The utility model will be further described in connection with the drawings:

[0020] As shown in Figure 2 , 3 , an adjustable fixture for welding relay mounting ear cover assembly, including mounting plate 1, cover positioning block 2, mounting ear positioning block 3, stop block 4, adjusting screw 5 and large screw 6;

[0021] One side of mounting plate 1 is provided with four adjusting grooves, and adjusting screw 5 is arranged in each adjusting groove; a screw hole is formed between the upper two adjusting grooves, and large screw 6 is arranged in the screw hole;

[0022] The other side of mounting plate 1 is provided with upper and lower T-shaped sliding grooves;

[0023] Cover positioning block 2 is two, and is separately arranged in the lower T-shaped sliding groove; one end of cover positioning block 2 is connected with adjusting screw 5; adjusting screw 5 is moved left and right, cover positioning block 2 can slide in the lower T-shaped sliding groove, and the position of cover positioning block 2 can be fixed by tightening adjusting screw 5.

[0024] Mounting ear positioning block 3 is two, and is separately arranged in the upper T-shaped sliding groove; one end of mounting ear positioning block 3 is connected with adjusting screw 5; adjusting screw 5 is moved left and right, mounting ear positioning block 3 can slide in the upper T-shaped sliding groove, and the position of mounting ear positioning block 3 can be fixed by tightening adjusting screw 5.

[0025] The stop block 4 is arranged between the two mounting ear positioning blocks 3, and is fixedly connected with the large screw 6; the position of the stop block 4 is adjusted by moving the large screw 6 forward and backward, and the stop block 4 can be fixed by tightening the large screw 6.

[0026] In this invention, the positioning references for the welding process outer cover 7 and the mounting ears 8 are both the product shape. Adjusting the left and right distance between the outer cover positioning block 2 and the mounting ear positioning block 3 can accommodate outer covers 7 and mounting ears 8 of different shapes and sizes, thereby achieving the positioning of outer cover components of different models. The welding height of the mounting ears 8 on the outer cover 7 can be adjusted by adjusting the front and rear positions of the middle stop block 4, which is highly versatile, simple in structure, and easy to operate.
