Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts processing, and specifically relates to a welding fixture for processing automobile chassis parts. Background Art

[0002] The automobile chassis consists of four parts: transmission system, running system, steering system and braking system. The function of the chassis is to support and install the automobile engine and its components and assemblies, form the overall shape of the car, and receive the power of the engine to make the car move and ensure normal driving.

[0003] During the manufacturing process of the automobile chassis, some parts need to be connected by welding. In order to ensure the stability and accuracy of the welding operation, it is usually necessary to clamp and fix the parts to be welded. There are many types of welding fixtures in the prior art to meet the welding needs. For example, the application number is: CN202320873948.2, an automobile parts welding fixture, which places the parts between the opposite sides of the two clamping components, and drives the threaded rod to rotate by starting the external motor, so that the two clamping components move to the same side, thereby clamping the parts, and the parts can be welded. When the parts are special-shaped and the traditional chuck cannot stably clamp the special-shaped parts, the chuck can be replaced by replacing the clamping components. Therefore, different special-shaped parts can be adapted through different clamping components, so that different parts can be stably clamped, ensuring the stability and accuracy of welding during the welding process.

[0004] Although the above-mentioned clamps can effectively clamp parts, they still have some shortcomings in actual use. First, when it is necessary to clamp parts of different shapes, the clamping components must be replaced. This frequent replacement is not only time-consuming and laborious, but also requires precise finding of the appropriate clamping components, making the entire operation process particularly cumbersome.

[0005] Secondly, when welding automobile parts, the rotation function of the welded parts is not provided, which brings significant inconvenience to the welding operation of the staff, thereby affecting the overall welding efficiency.

[0006] In addition, the debris and dust generated during welding easily slide down the sliding groove into the adjustment groove. The accumulation of these debris and dust easily blocks the adjustment groove, resulting in the movement of the slider being hindered, further affecting the convenience and performance of the equipment.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0041] Please see attached Figure 1-Figure 8 As shown, the utility model provides a welding fixture for processing automobile chassis parts, including a base 1;

[0042] A swivel seat 2, the swivel seat 2 is rotatably connected in the base 1;

[0043] A fixing mechanism 3, wherein the fixing mechanism 3 is arranged on the rotating seat 2;

[0044] The groove 4 is annularly distributed and opened on the top surface of the base 1, and the bottom surface of the rotating base 2 is fixedly connected with a protrusion 5;

[0045] The fixing mechanism 3 includes an adjusting portion 31 , which is disposed on the rotating seat 2 , a rotating portion 32 is disposed on the adjusting portion 31 , and a clamping portion 33 is disposed on the rotating portion 32 .

[0046] In a preferred embodiment, please refer to Figure 2-Figure 4 The adjusting part 31 includes a turntable 311, which is rotatably connected to the inner wall of the turntable 2. The turntable 311 is provided with arc grooves 312 in a ring-shaped manner. A motor 313 is fixedly installed on the bottom surface of the inner cavity of the turntable 2, and the output shaft of the motor 313 is fixedly connected to the turntable 311. The upper end of the turntable 2 is provided with sliding grooves 314 in a ring-shaped manner. A moving block 315 is slidably connected in the sliding groove 314. A round rod 316 is fixedly connected to the bottom surface of the moving block 315, and the lower end of the round rod 316 is inserted in the arc groove 312. One end of the moving block 315 is fixedly connected to a U-shaped rod 317.

[0047] In this embodiment, the parts to be welded are placed at the top center of the rotating seat 2. Subsequently, the motor 313 is started to drive the rotating disk 311 to rotate. During the rotation of the rotating disk 311, the arc groove 312 interacts with the round rod 316, causing the round rod 316 to move. This displacement drives the moving block 315 to move along the sliding groove 314, prompting the U-shaped rod 317 to push the rotating part 32 and the clamping part 33 closer to each other, thereby achieving a stable clamping of the parts. After the clamping is completed, the welding operation can be carried out. On the contrary, if the parts need to be disassembled, it is only necessary to control the motor 313 to rotate in the opposite direction so that the clamping parts 33 are moved away from each other.

[0048] Secondly, please refer again to Figure 5-Figure 8 The rotating part 32 includes a support seat 321, which is fixedly connected to one end of the U-shaped rod 317. A slot 322 is provided on the support seat 321. A locking slot 323 is provided at the upper end of the slot 322 in an annular manner. A cylinder 324 is inserted in the slot 322. A locking block 325 is provided in an annular manner on the cylinder 324. A tension spring 326 is fixedly connected to the lower end of the cylinder 324. A ring 327 is fixedly connected to the lower end of the tension spring 326, and the ring 327 is rotatably connected to the bottom surface of the inner cavity of the slot 322. Among them, the clamping part 33 includes a clamping block 331, which is fixedly connected to the upper end of the cylinder 324. A movable slot 332 is provided on one side of the clamping block 331 in an array. A clamping rod 333 is inserted in the movable slot 332, and a compression spring 334 is connected between the clamping rod 333 and the movable slot 332.

[0049] In this embodiment, when fixing parts with regular shapes (such as square and cylindrical), the four clamping blocks 331 can be directly brought close to each other for clamping. For irregular parts with special shapes, the user first lifts the clamping block 331, stretches the tension spring 326, and makes the locking block 325 disengage from the locking groove 323. At this time, the clamping block 331 loses its limit. The user can rotate the clamping block 331 180 degrees, and then release the clamping block 331. The tension spring 326 will generate a reset force to drive the cylinder 324 to move downward. The locking block 325 on the cylinder 324 is then inserted into the locking groove 323 at the upper end of the slot 322. At this time, the clamping block 331 will not be able to rotate. Then, the motor 313 is started to drive the clamping blocks 331 to approach each other, and the irregular parts with special shapes are clamped by using a plurality of clamping rods 333 distributed in an array at one end of the clamping block 331. During the clamping process, the clamping rod 333 that is resisted will move into the movable groove 332 and compress the compression spring 334, so that multiple clamping rods 333 can be in close contact with the surface of the part, and the part can be firmly clamped from four directions to obtain a better fixing effect.

[0050] In a preferred embodiment, please refer to Figure 4 The groove 4 is hemispherical, one end of the protrusion 5 is also hemispherical, and the protrusion 5 is made of rubber.

[0051] In this embodiment, during the welding process, the user can rotate the rotating seat 2 to facilitate welding on different surfaces of the part, which provides significant operating convenience for the staff and improves the overall welding efficiency. In addition, the rubber protrusion 5 at the bottom of the rotating seat 2 and the groove 4 contact each other to produce a damping effect, effectively preventing the rotating seat 2 from rotating at will, and ensuring stability during the welding process.

[0052] Next, please refer to Figure 5 The moving block 315, the U-shaped rod 317 and the support seat 321 are an integral structure, which is integrally formed. The stability and durability of the structure are significantly improved. In practical applications, this overall structure can maintain a stable operating state whether under high-load working conditions or during frequent movements and adjustments, providing solid support and guarantee for the continuous and efficient operation of the equipment.

[0053] The working principle of the utility model is as follows: first, the parts to be welded are placed at the top center of the rotating seat 2. Then, the motor 313 is started to drive the rotating disk 311 to rotate. During the rotation of the rotating disk 311, the arc groove 312 interacts with the round rod 316, causing the round rod 316 to be displaced. This displacement drives the moving block 315 to move along the sliding groove 314, prompting the U-shaped rod 317 to push the rotating part 32 and the clamping part 33 closer to each other, thereby achieving a stable clamping of the parts. After the clamping is completed, the welding operation can be carried out. On the contrary, if the parts need to be disassembled, it is only necessary to control the motor 313 to rotate in the opposite direction so that the clamping parts 33 are moved away from each other.

[0054] When fixing parts with regular shapes (such as square and cylindrical), the four clamping blocks 331 can be directly brought close to each other for clamping. For irregular parts with special shapes, the user first lifts the clamping block 331, stretches the tension spring 326, and makes the locking block 325 disengage from the locking groove 323. At this time, the clamping block 331 loses its limit. The user can rotate the clamping block 331 180 degrees, and then release the clamping block 331. The tension spring 326 will generate a reset force to drive the cylinder 324 to move downward. The locking block 325 on the cylinder 324 is then inserted into the locking groove 323 at the upper end of the slot 322. At this time, the clamping block 331 will not be able to rotate. Then, the motor 313 is started to drive the clamping blocks 331 to approach each other, and the irregular parts with special shapes are clamped by using the multiple clamping rods 333 distributed in an array at one end of the clamping block 331. During the clamping process, the clamping rod 333 that is resisted will move into the movable groove 332 and compress the compression spring 334, so that multiple clamping rods 333 can be in close contact with the surface of the part, and the part can be firmly clamped from four directions to obtain a better fixing effect.

[0055] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
