[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see the attached Figure 1 -Attached Figure 4 A welding fixture for automobile parts includes a workbench 1, and a clamping assembly is provided on the top surface of the workbench 1. The clamping assembly includes two main clamping plates 2 arranged on the top surface of the workbench 1, and the top surfaces of the main clamping plates 2 are respectively provided with a first sub-clamping plate 201 and a second sub-clamping plate 202. The interior of the main clamping plate 2 is a hollow structure, and a sliding frame 203 is provided inside the main clamping plate 2. Both ends of the sliding frame 203 pass through the inner top surface of the main clamping plate 2 and are detachably fixed to the bottom surface of the first sub-clamping plate 201.

[0022] In the embodiment, a dual-axis motor 204 is fixed inside the main clamping plate 2, and the upper and lower drive shafts of the dual-axis motor 204 can rotate respectively. The inner bottom surface of the main clamping plate 2 is rotatably connected to the first screw rod 205, and the top end of the first screw rod 205 is threadedly connected to the bottom surface of the sliding frame 203. The top end of the first screw rod 205 is fixed to the lower end drive shaft of the dual-axis motor 204. A support plate 206 is fixed to one side of the inner part of the main clamping plate 2. The inner part of the support plate 206 is rotatably connected to the second screw rod 207, and the second screw rod 207 is fixed to the upper end drive shaft of the dual-axis motor 204. The outer wall of the second screw rod 207 is threadedly connected to a threaded sleeve 208, and the top end of the threaded sleeve 208 passes through the inner top surface of the main clamping plate 2 and is fixed to the bottom surface of the second auxiliary clamping plate 202. A sliding groove 209 is provided on the top surface of the workbench 1. The sliding groove 209 is internally rotatably connected to a bidirectional screw rod 210. The main clamping plate 2 and the bidirectional screw rod 210 are connected in a rotating manner. The outer wall is threadedly connected, and a driving motor is fixed to the right side of the workbench 1. The driving shaft of the driving motor passes through the right side of the workbench 1 and extends to the inside of the sliding groove 209 and is fixed to the right end of the bidirectional screw rod 210. Through the setting of the main clamping plate 2, conventional automobile parts can be clamped, and then by setting the first sub-clamping plate 201 and the second sub-clamping plate 202 on the top surface of the main clamping plate 2, longer automobile parts can be clamped, or two parts can be clamped separately. After clamping, the two parts to be welded can be brought close together by driving the main clamping plate 2 for welding, and the first sub-clamping plate 201 and the second sub-clamping plate 202 can be freely lifted and lowered, so that the height of the parts clamped on both sides can be freely adjusted, and it has a high adaptability to parts that need to be staggered welded. For example, when two long cylindrical parts need to be welded on the outer wall, ordinary clamps are difficult to clamp and position, but this device can easily achieve this, which increases the applicability of the device.

[0023] In an embodiment, two limiting cylinders 3 are fixed to the inner bottom surface of the main clamping plate 2, and the limiting cylinder 3 and the bottom surface of the sliding frame 203 are inserted through the limiting cylinder 3, and a first limiting rod 301 is inserted inside the limiting cylinder 3, and the top end of the first limiting rod 301 passes through the inner top surface of the main clamping plate 2 and is fixed to the bottom surface of the second sub-clamping plate 202, and two second limiting rods 302 are fixed inside the sliding groove 209, and the outer wall of the main clamping plate 2 and the second limiting rod 302 are slidingly arranged. Through the setting and use of the limiting cylinder 3, the first limiting rod 301 and the second limiting rod 302, the main clamping plate 2, the first sub-clamping plate 201 and the second sub-clamping plate 202 can be limited and auxiliary supported, so that the main clamping plate 2, the first sub-clamping plate 201 and the second sub-clamping plate 202 are more stable when moving, and the automobile parts are clamped more stably.

[0024] In the embodiment, connecting rods 4 are fixed on both sides of the first and second clamping plates 201 and 202 where they are close to each other, a universal ball 401 is fixed at one end of the connecting rod 4, and a bonding plate 402 is fixed on the outer wall of the universal ball 401. Through the setting and use of the universal ball 401, the bonding plate 402 can rotate at a certain angle, thereby adapting to the surface curvature of the automobile parts for deflection, increasing the clamping area, and increasing the stability of the clamping.

[0025] In the embodiment, the bonding sides of the bonding plate 402 and the main clamping plate 2 and the parts are fixed with rubber pads 5. Through the setting of the rubber pads 5 and the utilization of the deformation ability and the larger friction coefficient of the rubber pads 5, the surface curvature of the automobile parts can be better adapted and the automobile parts can be clamped more stably.

[0026] In the embodiment, bolts 6 are inserted into the top surface of the first sub-clamping plate 201 near the front and rear sides, and the two bolts 6 are respectively threadedly connected to the two ends of the sliding frame 203. By setting the first sub-clamping plate 201 to be detachably connected to the sliding frame 203 using bolts 6, when two long automobile parts are difficult to take out after welding, the first sub-clamping plate 201 can be disassembled to facilitate taking out the parts.

[0027] Working principle: When in use, place ordinary short parts between the two main clamping plates 2, then start the drive motor to drive the bidirectional screw 210 to rotate. Under the action of the threaded connection between the main clamping plates 2 and the bidirectional screw 210, the two main clamping plates 2 approach each other and clamp the parts, and then the welding operation can be started. When it is necessary to process longer parts or weld two parts, first insert the longer parts between the first sub-clamping plates 201 and the second sub-clamping plates 202 on both sides. If the end of the part is large and difficult to insert, you can remove the bolt 6 to disassemble the first sub-clamping plate 201 and the sliding frame 203, and then put the part in. Then start the dual-axis motor 204 to drive the upper and lower drive shafts to rotate respectively. The first screw rod 205 and the second screw rod 207 rotate, and under the action of the threaded connection between the sliding frame 203 and the first screw rod 205, and the threaded connection between the threaded sleeve 208 and the second screw rod 207, the sliding frame 203 and the threaded sleeve 208 move upward or downward, and push the first sub-clamping plate 201 and the second sub-clamping plate 202 away from or close to each other, so that the first sub-clamping plate 201 and the second sub-clamping plate 202 on both sides clamp the long parts from two places. When two parts need to be welded, it is only necessary to clamp the two parts on both sides respectively, and then drive the main clamping plate 2 to bring the two parts to be welded close together, and perform the welding operation on the fitting part of the two parts.

[0028] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
