Description

Technical Field

[0001] This utility model relates to the field of automotive repair equipment technology, specifically to an automotive sheet metal clamping device. Background Technology

[0002] In today's automotive repair industry, sheet metal repair is an extremely crucial and frequently performed task. From minor scratches causing dents to severe collisions resulting in body deformation, sheet metal repair plays an indispensable role, and its quality directly affects the appearance and safety of a vehicle.

[0003] There are various types of automotive sheet metal clamping devices, among which the common manual screw-tightening clamping device relies on a simple mechanical structure to clamp sheet metal parts by manually tightening screws for welding, repair, and other operations. While this traditional clamping method is simple in structure, low in cost, and easy to understand, manual operation consumes a significant amount of time and effort for repair personnel to adjust the clamping degree. Insufficient force can cause the sheet metal parts to shift during repair, significantly reducing repair accuracy, while excessive force can damage the surface of the sheet metal parts, increasing repair costs and time. Furthermore, traditional clamping devices have poor adaptability to sheet metal parts of different shapes and sizes, often requiring the replacement of different clamps, reducing repair efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that most existing automotive sheet metal clamping devices are manually operated, which not only consumes a lot of time and energy of maintenance personnel to adjust the clamping degree, but also has poor adaptability to sheet metal parts of different shapes and sizes.

[0024] Example 1:

[0025] As per the instruction manual Figure 1-4 As shown, an automotive sheet metal clamping device includes an adjusting plate 1, a handle 2 at the bottom of the adjusting plate 1, the handle 2 being a plastic shell, a vertical connecting rod 3 fixedly mounted on one side of the top of the adjusting plate 1, the connecting rod 3 being welded to the top of the adjusting plate 1 and forming an L-shaped structure with the adjusting plate 1, a guide groove 4 being provided between the adjusting plate 1 and the connecting rod 3 and the handle 2, a clamping rod 5 being slidably connected inside the guide groove 4, the connecting rod 3 and the clamping rod 5 being located on the same side of the adjusting plate 1, and an extension rod 6 being threadedly connected to the end away from the adjusting plate 1, and clamping pads 7 being provided on the opposite side of the two extension rods 6.

[0026] In this utility model, a telescopic cylinder 8 is provided on the side of the adjustment plate 1 away from the connecting rod 3. The telescopic cylinder 8 is rotatably connected to the telescopic rod 10 through the threaded rod 9. One end of the clamping rod 5 passes through the guide groove 4 and is provided with a connecting plate 12. The connecting plate 12 is set perpendicular to the adjustment plate 1. The lower part of the connecting plate 12 is fixedly connected to the top of the telescopic rod 10 by the first bolt 13. The top of the telescopic rod 10 is fixedly connected to one end of the clamping rod 5. The bottom of the telescopic cylinder 8 is connected to the threaded rod 9 through the motor 11. At the connection between the motor 11 and the threaded rod 9, the output power of the motor 11 can be reduced by adding a reduction gear set, and a worm gear mechanism is provided to prevent the threaded rod 9 from reversing. The handle 2 is provided with multiple heat dissipation vents 20 at the motor 11.

[0027] In this utility model, one end of the connecting rod 3 and the clamping rod 5 is provided with a threaded hole 14 for connection, and one end of the extension rod 6 is provided with a stud 15. The stud 15 is threadedly connected to the threaded hole 14, and the diameter of the extension rod 6 matches that of the connecting rod 3 and the clamping rod. In use, extension rods of different lengths can be replaced according to the actual situation to adapt to different clamping positions.

[0028] In this utility model, the clamping pad 7 includes a plastic block 16 and a rubber pad 17 in sequence from the extension rod 6 outwards. One side of the plastic block 16 is fixedly connected to the extension rod 6 by a second bolt 18. The side of the rubber pad 17 away from the plastic block 16 is provided with anti-slip texture 19. At the same time, clamping pads 7 of different sizes and shapes can be replaced as needed to perform adaptive clamping operations.

[0029] In this utility model, a controller 21 is provided on the side of the handle 2 near the connecting rod 3, and the controller 21 is electrically connected to the motor 11 to control the output power of the motor 11. At the same time, the controller 21 is electrically connected to the control button 22 and the charging interface 23 on the handle 2. The external power supply is provided by the charging interface 23, or the controller 21 is equipped with a built-in battery for internal power supply, so that it can be used for mobility.

[0030] In practical implementation, when it is necessary to clamp sheet metal parts, the motor 11 is started via the control button 22 connected to the controller 21. The motor 11 drives the threaded rod 9 to rotate, and the rotation of the threaded rod 9 causes the telescopic rod 10 to move linearly within the telescopic cylinder 8. The extension and retraction of the telescopic rod 10 pushes the clamping rod 5 to slide within the guide groove 4, thereby changing the distance between the clamping rod 5 and the connecting rod 3, thus achieving the clamping or loosening of the sheet metal parts. During the clamping process, the plastic block 16 on the clamping pad 7 provides strength, the rubber pad 17 protects the surface of the sheet metal parts from scratches, and the anti-slip texture 19 on the rubber pad 17 increases the friction between the rubber pad and the sheet metal parts, making the clamping more stable. The size and other shapes of the clamping pad 7 can be changed as needed.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
