[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 An easy-to-grip automotive welding fixture includes a frame 1, a worktable 2 fixedly connected to the top of the frame 1, a support plate 3 fixedly connected inside the worktable 2, a round shaft 4 fixedly connected to the left side inside the frame 1, a left clamping plate 5 movably connected to the surface of the round shaft 4, the top of the left clamping plate 5 extending to the top of the worktable 2, a spring 6 fixedly connected to the surface of the left clamping plate 5, the top of the spring 6 fixedly connected to the bottom of the worktable 2, a guide post 7 fixedly connected to the right side inside the frame 1, a right clamping plate 8 slidably connected to the front and rear sides of the surface of the guide post 7, the top of the right clamping plate 8 extending to the top of the worktable 2, and a control mechanism fixedly connected to the bottom inside the frame 1.

[0022] Please see Figure 1-4 The control mechanism includes an electric cylinder 91, which is fixedly connected to the bottom of the inner wall of the frame 1. The output end of the electric cylinder 91 extends through to the top of the support plate 3. The output end of the electric cylinder 91 is fixedly connected to a lifting plate 92. Connecting pieces 93 are fixedly connected to the front and rear sides of the top right side of the lifting plate 92. The surface of the connecting piece 93 is movably connected to the bottom of the right clamping plate 8. A pulley 94 is hinged to the bottom of the left clamping plate 5. The surface of the pulley 94 is in contact with the top of the lifting plate 92.

[0023] Furthermore, by setting up pulley 94, it can act on the left clamping plate 5, realizing the linkage control of the left and right clamping plates 8, eliminating the need for manual operation and improving the degree of automation of clamping; the electric cylinder 91 has a stable driving force and can accurately control the clamping force, ensuring that the workpiece is firmly clamped and not easily deformed, while simplifying the operation process and improving welding efficiency.

[0024] Please see Figure 1-3 Both the right clamping plate 8 and the left clamping plate 5 are threaded with fine-tuning parts 10, which are located on the top of the worktable 2.

[0025] Furthermore, by setting the fine-tuning component 10, the position of the clamping plate can be finely adjusted after initial clamping, which can adapt to automotive workpieces of different sizes and shapes, improving the versatility of the fixture; the fine-tuning function ensures the accuracy of workpiece clamping, avoids the impact of clamping position deviation on welding quality, and enhances the practicality of the fixture.

[0026] Please see Figure 1-4 Vertical rods 11 are fixedly connected to both sides of the bottom of the lifting plate 92, and the bottom of the vertical rods 11 extends through to the bottom of the support plate 3.

[0027] Furthermore, the vertical rod 11 guides the lifting movement of the lifting plate 92, preventing it from shifting or swaying during movement and ensuring the synchronicity and stability of the left and right clamping plates 8. The vertical rod 11 also enhances the load-bearing capacity of the lifting plate 92 and improves the overall stability of the clamping fixture.

[0028] Please see Figure 1-4 A sliding sleeve 12 is fitted onto the surface of the vertical rod 11, and the top of the sliding sleeve 12 is fixedly connected to the bottom of the support plate 3.

[0029] Furthermore, the sliding sleeve 12 allows the vertical rod 11 to drive the lifting plate 92 to move more smoothly, reducing component wear; at the same time, the sliding sleeve 12 further strengthens the guiding and limiting function of the vertical rod 11, ensuring the stability of the movement trajectory of the lifting plate 92 and extending the service life of the fixture.

[0030] Please see Figure 1-4 A reinforcing block 13 is fixedly connected to the top of the surface of the vertical rod 11, and the top of the reinforcing block 13 is fixedly connected to the bottom of the lifting plate 92.

[0031] Furthermore, by setting the reinforcing block 13, the connection between the vertical rod 11 and the lifting plate 92 can be prevented from loosening or breaking due to excessive force during long-term use, thereby improving the durability and safety of the structure and ensuring the long-term stable operation of the clamp.

[0032] Please see Figure 1 Ventilation slots 14 are provided at the bottom of the front and rear sides of the frame 1, and the ventilation slots 14 are located at the front and rear sides of the electric cylinder 91.

[0033] Furthermore, the ventilation groove 14 effectively enhances airflow during operation of the electric cylinder 91, helps dissipate heat from the electric cylinder 91, prevents the electric cylinder 91 from being affected by excessively high operating temperature over a long period of time, or shortens its service life, ensures stable operation of the control mechanism, and improves the reliability of the fixture.

[0034] The specific implementation process of this utility model is as follows: When in use, the left clamping plate 5 and the right clamping plate 8 are in a closed state as shown in the figure. The workpiece is placed on the top of the worktable 2, and then the left clamping plate 5 and the right clamping plate 8 are closed. The fine adjustment part 10 is rotated so that the left clamping plate 5 and the right clamping plate 8 can be precisely fitted with the workpiece.

[0035] When it is necessary to open the left clamping plate 5 and the right clamping plate 8, the electric cylinder 91 is activated. The electric cylinder 91 drives the lifting plate 92 to move upward. The lifting plate 92 drives the connecting piece 93 to move upward. The connecting piece 93 drives the right clamping plate 8 to move upward. During the upward movement of the right clamping plate 8, it will be guided by the guide column 7, causing the right clamping plate 8 to flip to the right while moving upward. At the same time, the lifting plate 92 pushes the pulley 94 to move upward. The pulley 94 drives the left clamping plate 5 to rotate. The left clamping plate 5 compresses the spring 6. At this time, both the left clamping plate 5 and the right clamping plate 8 are separated from the surface of the workpiece.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
