[0014] To make the technical means, creative features, purposes and effects achieved by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0015] As Figs. 1 to 4 Shown, a kind of welding fixtures, including base 100, the top of the base 100 one end is equipped with fixed hole 113, fixed hole 113 is connected with fixed seat 102 using screw, the top of the fixed seat 102 is fixed with first mounting block 103, first mounting block 103 is hingedly equipped with fixed clamp 104, the end of the fixed clamp 104 is equipped with first C-type pressure block 105, the top of the base 100 is equipped with support seat 110 away from fixed seat 102 side, the top of the support seat 110 is equipped with slide rail 111, moving seat 112 is slidably equipped in slide rail 111, the top of the moving seat 112 is fixed with second mounting block 107, second mounting block 107 is hingedly equipped with sliding clamp 106, the end of the sliding clamp 106 is equipped with second C-type pressure block 108.

[0016] With the fixed seat 102 as the reference point and the main support structure of the welding fixture device, the fixed clamp 104 is used to firmly fix one end of the plate to be welded 109, and according to the length of the plate to be welded 109, the sliding clamp 106 is adjusted to the appropriate position by moving the seat 112 on the slide rail 111 in the axial direction of the slide rail 111, and the sliding clamp 106 is used to keep effective clamping on the other end of the plate to be welded 109. By setting the sliding clamp 106, the welding fixture can easily adapt to plates of different lengths, greatly improving the flexibility and scope of application of the clamp system. Then, the first C-shaped block 105 and the second C-shaped block 108 are used to stably clamp the plate to be welded 109, providing ideal working conditions for subsequent welding. The design of the C-shaped block effectively compensates for the unevenness of the plate, ensures uniform distribution of clamping force, maintains high stability of the assembly of the welded part, improves processing quality, and simplifies the operation process, reduces the changeover time, and significantly improves the overall production efficiency. At the same time, the fixed seat 102, the support seat 110 and the C-shaped block can be replaced according to the needs to adapt to the fillet welds of different angles.

[0017] In this embodiment, the support seat 110 is set to a certain angle of inclination, and the plate to be welded 109 is installed on the inclined surface of the support seat 110. The first C-shaped block 105 and the second C-shaped block 108 have a wear-resistant layer on the side in contact with the plate to be welded 109.

[0018] The support seat 110 is designed at a certain angle to cooperate with the first C-shaped block 105 and the second C-shaped block 108 to assemble the plate to be welded 109 of different angles.
