In the automotive manufacturing industry, welding is a key joining process that is widely used in the production of automotive parts. As a direct result of welding operations, the quality and appearance of welds have a significant impact on the performance, safety, and durability of the entire vehicle.

[0003] Uneven weld surfaces are often produced during the welding of automotive parts. This not only affects the aesthetics of the automotive parts, but may also reduce their mechanical strength and sealing performance. Therefore, it is necessary to grind the weld surface. Traditional grinding equipment can only clamp long strip automotive parts of a fixed size. When it is necessary to grind long strip automotive parts of other sizes, it cannot clamp and fix them, which is not conducive to grinding long strip automotive parts of different sizes. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a weld grinding device for automotive parts production.

Two connecting rods are slidably inserted into the baffle and located below the working plate. One end of the two connecting rods is fixedly connected to two connecting blocks respectively, and a pull plate is fixedly installed at the other end of the two connecting rods. A spring is sleeved on the connecting rod, and both ends of the spring are fixedly connected to one side of the baffle and one side of the connecting block respectively.

[0008] In addition, a preferred structure is that the worktable has three lower grooves, and guide rods are installed in the lower grooves at both ends.

[0009] In addition, a preferred structure is that a motor is fixedly installed on one side of the worktable, and the motor drive mounting threaded rod is located in the centrally located lower groove.

[0010] In addition, a preferred structure is that a nut pair is fixedly installed at the center of the bottom of the working plate, and sliding sleeves are fixedly installed at both ends of the bottom of the working plate, with the two sliding sleeves located on both sides of the nut pair.

[0011] In addition, a preferred structure is that the nut assembly is sleeved on the threaded rod, and the two sliding sleeves are respectively slidably sleeved on the two guide rods.

[0012] In addition, a preferred structure is that electromagnetic plates are fixedly installed at both ends of the top of the fixed clamping plate, and the bottom of the electromagnetic plates is provided with a sliding groove.

[0013] In addition, a preferred structure is that magnetic sliders are fixedly installed at both ends of the top of the movable clamping plate, and the magnetic sliders slide within the groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, by pulling the pull plate, the movable clamping plate is moved, thereby allowing long strip-shaped automotive parts of different sizes to be clamped and fixed on the work plate by the movable clamping plate and the fixed clamping plate, which facilitates the welding and grinding of long strip-shaped automotive parts of different sizes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A weld grinding device for automotive parts production includes a workbench 1, a multi-axis grinding mechanism 2 installed on the top of the workbench 1, a work plate 3 slidably arranged on the workbench 1, two through slots 31 opened on the work plate 3, and a movable clamping plate 13 arranged on the work plate 3. Connecting blocks 16 are fixedly installed at both ends of the bottom of the movable clamping plate 13 and slidably located in the through slots 31.

[0025] Among them, a fixed clamping plate 7 is fixedly installed at the top of one side of the working plate 3, and a baffle 8 is fixedly installed at the bottom of the other side of the working plate 3. Two connecting rods 10 are slidably inserted into the baffle 8 and located below the working plate 3. One end of the two connecting rods 10 is fixedly connected to two connecting blocks 16 respectively, and a pull plate 11 is fixedly installed at the other end of the two connecting rods 10. A spring 12 is sleeved on the connecting rod 10, and the two ends of the spring 12 are fixedly connected to one side of the baffle 8 and one side of the connecting block 16 respectively.

[0026] Meanwhile, three lower grooves 101 are provided on the workbench 1, and guide rods 4 are provided in the lower grooves 101 at both ends.

[0027] Furthermore, a motor 5 is fixedly installed on one side of the workbench 1, and the motor 5 drives the threaded rod 6 located in the centrally located lower groove 101.

[0028] Meanwhile, a nut pair 14 is fixedly installed at the center of the bottom of the working plate 3, and sliding sleeves 15 are fixedly installed at both ends of the bottom of the working plate 3, with the two sliding sleeves 15 located on both sides of the nut pair 14.
