Description

Technical Field

[0001] This utility model relates to the field of workpiece welding technology, and in particular to a fixing fixture for welding assembly. Background Technology

[0002] In the welding assembly process, the accurate positioning and reliable fixing of multiple plates are the key to ensuring welding quality.

[0003] Currently, traditional welding operations often use general-purpose fixtures or manual hand-held methods for fixing, which not only makes it difficult to guarantee positioning accuracy, but also suffers from low efficiency, high labor intensity, and repetitiveness. Especially in situations where multiple workpieces need to be welded in layers or steps, operators need to adjust the workpiece position multiple times, which can easily lead to welding deviations due to accumulated errors, seriously affecting the consistency of finished products and assembly accuracy. When welding different plates together continuously, repeated disassembly or adjustment is still required, which reduces production efficiency. Therefore, it is necessary to design a fixing fixture for welding assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing fixture for welding assembly, so as to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A welding assembly fixture includes a base plate and further includes:

[0007] A locking unit is provided, and two locking units are provided. The two locking units are located on the top of the substrate, and both locking units are used to lock the first board to be welded.

[0008] A limiting unit is movably mounted on the top of the substrate, and the limiting unit is used to fix the second plate to be welded;

[0009] A fixing unit is provided, which is disposed on the top of the substrate, and the fixing unit is used to fix the third board to be welded.

[0010] By adopting the above technical solution, the first plate to be welded is placed on the substrate and then fixed with two locking units. Then, the limiting unit is placed on the substrate so that the front end of the limiting unit is in contact with the first plate to be welded. The second plate to be welded is then placed in the limiting unit to complete the welding work of the first and second plates to be welded. Next, the third plate to be welded is placed and fixed at the top of the fixing unit to complete the welding work of the second and third plates to be welded. This achieves the purpose of improving welding quality and productivity, and making it easier for operators to complete the welding work.

[0011] In a further embodiment, the locking unit includes a fixing block, a screw, and a spring. The top of the fixing block is provided with a through-hole. The top of the base plate is provided with two downward threaded holes. The spring is provided at one bottom end of the fixing block. The screw includes a shank portion and a nut portion. The shank portion of the screw passes through the through-hole and extends to the outside of the through-hole. The shank portion of the screw is screwed into a threaded hole. The nut portion of the screw is located at the top of the through-hole.

[0012] By adopting the above technical solution, rotating the screw downwards causes the fixing block to move downwards, thereby pressing the fixing block against the first plate to be welded. One locking unit is located at the top right end of the substrate to prevent the first plate to be welded from moving in the left-right direction, and another locking unit is located at the top left end of the substrate to prevent the first plate to be welded from moving in the front-back direction, thereby achieving the purpose of limiting and fixing the first plate to be welded.

[0013] In a further embodiment, the fixing unit includes a first support frame, a second support frame, and a third support frame. The first support frame, the second support frame, and the third support frame have the same structure. The first support frame is located at the top right front end of the substrate, the second support frame is located at the top right rear end of the substrate, and the third support frame is located at the top left rear end of the substrate.

[0014] In a further embodiment, the first support frame includes a first cylinder and a second cylinder, the second cylinder is fixedly installed on the top of the first cylinder, the diameter of the second cylinder is smaller than the diameter of the first cylinder, and the side wall of the second cylinder is provided with threads.

[0015] By adopting the above technical solution, the third plate to be welded is provided with three corresponding through holes, and the diameter of the through holes is larger than the diameter of the second cylinder and smaller than the diameter of the first cylinder. Therefore, the third plate to be welded can pass through the second cylinder and be placed on the top of the first cylinder. Then, the third plate to be welded is locked on the first support frame, the second support frame and the third support frame by three nuts, thereby achieving the purpose of limiting and fixing the third plate to be welded.

[0016] In a further embodiment, the limiting unit includes a rectangular block, a rectangular plate, and a handle. The handle is fixedly installed at the rear of the rectangular block. The front and bottom ends of the rectangular block are both fully open. The left end of the rectangular block is provided with an integrally formed first protrusion, and the right end of the rectangular block is provided with an integrally formed second protrusion. The bottom front end of the first protrusion has an avoidance notch. The rectangular plate is fixedly installed on the top of the first and second protrusions. Both ends of the front part of the rectangular block are provided with a rearward first locking groove, and both ends of the front part of the rectangular block are provided with a rearward second locking groove. The middle front section of the rectangular plate is provided with a rearward avoidance groove.

[0017] By adopting the above technical solution, two second plates to be welded are provided. One end of each second plate to be welded is engaged in the first engagement groove, and the other end is engaged in the second engagement groove, thereby achieving the purpose of limiting and fixing the second plates to be welded, and finally completing the welding work between the first plate to be welded and the two second plates to be welded, and between the two second plates to be welded and the third plate to be welded.

[0018] In a further embodiment, a central post and a first fixed post are provided in the clearance groove. The central post and the first fixed post are both fixedly installed on the top of the substrate. The first fixed post is spaced apart at the left end of the central post, and the height of the first fixed post is the same as the height of the first cylinder.

[0019] In a further embodiment, a second fixing post is provided between the first cylinder and the second cylinder. The second fixing post is fixedly installed on the top of the substrate, and the structure of the second fixing post is the same as that of the first fixing post.

[0020] By adopting the above technical solution, the first and second fixed columns provide auxiliary support for the third plate to be welded.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. By placing the first plate to be welded on the substrate and fixing it with two locking units, then placing the limiting unit on the substrate so that the front end of the limiting unit is in contact with the first plate to be welded, and then placing the second plate to be welded inside the limiting unit, the welding work of the first and second plates to be welded is completed. Then, the third plate to be welded is placed and fixed on the top of the fixing unit, thereby completing the welding work of the second and third plates to be welded. This method can improve welding quality and productivity and facilitate the operation of the welding work. Attached Figure Description
