Description

Technical Field

[0001] This utility model relates to the field of rectangular tube processing technology, and in particular, to a multi-station laser welding fixture for rectangular tubes. Background Technology

[0002] Existing as Figure 1 The rectangular tube workpiece shown includes a tube body 4 and connecting lugs 5 located at the ends of the tube body 4. The connecting lugs 5 are fixed to the tube body 4 by welding. The traditional welding method involves manually splicing each connecting lug 5 to the rectangular tube before welding. This welding method is inefficient and easily causes operator fatigue. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a rectangular tube laser multi-station welding fixture.

[0004] The objective of this utility model is achieved through the following technical solution: A multi-station laser welding fixture for rectangular tubes includes a base, an abutment block is provided on the end face of the base, and at least one slot is provided on the end face of the base next to the abutment block. The side wall of the abutment block is adapted to abut the end face of a tube body, and the slot is adapted to insert a connecting ear. When the end face of the tube body abuts against the side wall of the abutment block, the connecting ear fits into the tube body.

[0005] Preferably, the slots are provided on both sides of the abutment block.

[0006] Preferably, the base is provided with fastening holes.

[0007] Preferably, the base has two opposing clamps, which are slidably connected to the base and cooperate to clamp the tube located between them.

[0008] Preferably, the abutment block is located in the middle of the base.

[0009] Preferably, the slots on both sides of the abutment block are symmetrically arranged.

[0010] Preferably, the base is provided with a sliding groove, and the clamp is slidably adapted to the sliding groove.

[0011] Preferably, the clamp is provided with a connecting bolt passing through the slide groove.

[0012] Preferably, the cross-section of the clamp is at least partially L-shaped.

[0013] The beneficial effects of this invention are as follows: Several slots are sequentially arranged on the support platform according to the width of the tube. A connecting lug is inserted into each slot. Then, several tubes are arranged side-by-side, ensuring a one-to-one correspondence between the tubes and the connecting lugs. Pushing the tubes towards the connecting lugs causes them to attach to their respective tubes, allowing the laser head to weld each tube. This invention enables batch welding of rectangular tubes, reducing operator workload and improving work efficiency. Attached Figure Description

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] like Figure 2 As shown, a rectangular tube laser multi-station welding fixture includes a base 1 with fastening holes 6. Fasteners can be fitted into the fastening holes 6 to mount the base 1 onto a welding table. At this time, the laser head of the welding table is positioned above the base 1. A stop block 2 is provided in the middle of the end face of the base 1, with its sidewall forming a stop surface. A slot 3 is also provided on the end face of the base 1 next to the stop surface.

[0018] During rectangular tube welding, the end face of the tube body 4 can be placed against the abutment surface, and the connecting lug 5 can be inserted into the slot 3. The mounting surface of the tube body 4 will then fit against the connecting lug 5. Subsequently, the laser head at the top can weld the fit between the two.

[0019] In a preferred embodiment, both side walls of the abutment block 2 are constructed as abutment surfaces, and slots 3 are evenly distributed on both sides of the abutment surfaces. For example, on each side of the abutment block 2, a plurality of slots 3 are arranged along the length direction of the abutment block 2. In particular, the spacing between adjacent slots 3 is sequentially set according to the width dimension of the tube body 4.

[0020] During the welding of rectangular tubes, connecting lugs 5 can be inserted into each slot 3, and then several tubes 4 can be arranged side by side so that several tubes 4 and several connecting lugs 5 can correspond one-to-one. Then, several tubes 4 are pushed to one side of several connecting lugs 5, and the connecting lugs 5 will be spliced ​​on the corresponding tubes 4. The laser head can weld each tube 4.

[0021] For example, the slots 3 on both sides of the abutment block 2 can be symmetrically arranged or have the same arrangement direction, thereby providing welding and mounting clamping for the connecting ears 5 at the ends of the tubes 4 in the same or different directions on both sides.

[0022] In some embodiments, the base 1 is further provided with a sliding groove 8, which extends along the length of the abutment block 2. Two clamps 7 are also slidably adapted within the sliding groove 8. The two clamps 7 are symmetrically arranged and can clamp the tube 4 located between them after sliding towards each other.

[0023] For example, a connecting bolt passing through the slide groove 8 can be provided on the clamp 7. The sliding of the connecting bolt within the slide groove 8 provides sliding guidance for the clamp 7. After the connecting bolt is tightened, the relative position of the clamp 7 is fixed, thereby providing a stable clamping force on the tube 4. In other configurations, the clamp 7 and the slide groove 8 can be slidably connected in a manner similar to a slide rail.

[0024] Under the clamping of the clamp 7, each tube 4 can fit against its corresponding connecting lug 5 with the smallest possible gap, which improves the accuracy and quality of the welding operation. In addition, the cross-section of the clamp 7 can be L-shaped or U-shaped, thus providing a relatively flat clamping surface facing the tube 4.

[0025] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
