Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, and more specifically, to a sheet metal grinding and bending fixture for sheet metal processing. Background Technology

[0002] Sheet metal processing is a crucial skill for sheet metal technicians. Patent publication number CN218312625U discloses a grinding and bending fixture for sheet metal processing, comprising a machine plate. A frame is mounted on the left side of the top of the machine plate. An electric push rod is mounted on the top of the frame, and a sliding shell is located inside the frame. A groove is formed on the outer wall of the sliding shell, and a slider is housed within the groove. A threaded groove is formed on the side wall of the slider, and a grinding motor is installed inside the slider. The motor shaft of the grinding motor passes through the outside of the slider, and a grinding disc is mounted on the motor shaft. A rotary motor is located on the right side inside the sliding shell. This invention, through the clamping and grinding mechanism on the machine plate, can form a stable clamp on the bent sheet metal during the grinding process, ensuring an efficient grinding effect on the grinding surface of the bent sheet metal.

[0003] In existing technologies, only one side of the bent sheet metal can be ground during the grinding process. Therefore, in the actual grinding process, workers need to disassemble and manually flip the bent sheet metal parts again to rotate them before grinding the second side. This process requires manual operation, and the presence of pressure plates poses certain safety hazards. Furthermore, batch flipping requires long periods of manual operation, consuming a lot of physical strength and reducing work efficiency, thus limiting the existing bending sheet metal tooling.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Example 1:

[0030] Please see Figure 1-5 A sheet metal grinding and bending fixture for sheet metal processing includes a work plate 1. Grinding components 2 are fixedly installed on both the left and right sides of the top of the work plate 1. A clamping component 3 is slidably installed between the two grinding components 2 at the top of the work plate 1. A bent sheet metal part 4 is placed at the bottom of the clamping component 3 at the top of the work plate 1. A sliding groove 101 is opened on the surface of the work plate 1. A mounting bracket 1 5 and a mounting bracket 2 6 are fixedly installed at the left and right ends of the sliding groove 101 at the bottom surface of the work plate 1, respectively. A motor 1 7 is fixedly installed inside the mounting bracket 1 5. A threaded rod 8 is fixedly sleeved on the output shaft of the motor 1 7. A limit plate 9 is fixedly installed at one end of the threaded rod 8. A transmission plate 10 is threadedly installed on the surface of the threaded rod 8. A mounting bracket 3 11 is fixedly installed at the top of the transmission plate 10. A mounting bracket 4 12 is fixedly installed at the top of the mounting bracket 3 11. A motor 2 13 is fixedly installed inside the side of the mounting bracket 3 11.

[0031] It should be noted that the working plate 1, grinding component 2 and clamping component 3 in this application are all integrated components of the prior art in the prior art documents. Compared with the settings in the prior art documents, the grinding component 2 in this application adopts a left-right symmetrical setting, which can improve grinding efficiency and is also a foreseeable technical means. The specific connection method and component structure inside are all existing mature technologies, so they will not be described in detail in this application.

[0032] The output shaft of the second motor 13 is fixedly sleeved with a stud 14. A transmission frame 15 is threaded onto the surface of the stud 14. A toothed plate 16 is engaged at the top of the transmission frame 15. A clamping platform 19 is rotatably mounted at the top of the mounting bracket 12. A positioning rod 18 is fixedly mounted at the left and bottom ends of the clamping platform 19. A rotating rod 1701 is rotatably mounted inside the positioning rod 18. An arc-shaped toothed disc 17 is fixedly mounted at the outer end of the rotating rod 1701. The surface of the arc-shaped toothed disc 17 and the top surface of the toothed plate 16 mesh with each other. A rotating hole 1901 is opened on the surface of the clamping platform 19. The shape of the rotating hole 1901 is adapted to the shape of the mounting bracket 12. An electric telescopic rod 20 is fixedly mounted inside the clamping platform 19. A magnetic plate 21 is fixedly mounted at the top of the electric telescopic rod 20.

[0033] Specifically, the mounting bracket 12 provides rotational support for the clamping table 19 and fixes the rotation center of the clamping table 19. The arc-shaped gear plate 17 limits the rotation angle and rotation range. Finally, the sliding groove 101 limits the overall sliding trajectory, realizing the rapid flipping of the bent sheet metal part 4. Secondly, the rotating rod 1701 and the positioning rod 18 can provide effective support during the rotation of the clamping table 19, preventing excessive clamping pressure from causing uneven force and breakage, thus improving the service life of the device. The limiting plate 9 can limit the threaded rod 8, ensuring its rotation in place and achieving the purpose of stable transmission.

[0034] There are two magnetic plates 21, and the included angle between the two adjacent magnetic plates 21 is set to 90 degrees. The surfaces of the magnetic plates 21 and the surfaces of the bent sheet metal parts 4 attract each other.

[0035] Specifically, the electric telescopic rod 20 can drive the magnetic plate 21 to extend and retract, thereby creating a more suitable clamping effect for the different thicknesses on both sides of the workpiece bending section. The magnetic attraction effect can better achieve the adsorption efficiency of the bottom of the plate, resulting in a better fixing effect. Finally, the center of the rotating hole 1901 is used as the axis of rotation of the clamping table 19 to ensure that the bent sheet metal clamped by the magnetic plate 21 will not collide with the work plate 1 during rotation, thus ensuring normal flipping and preventing mutual repulsion of movement.

[0036] The working principle of this utility model is as follows: After the bent sheet metal part 4 is fixed by the clamping component 3 and polished by the grinding component 2 on the same side, the clamping component 3 is first released from the clamping of the bent sheet metal part 4. At this time, the drive motor 7 and the second motor 13 are activated. Then, the toothed plate 16 and the arc-shaped toothed disc 17 drive the positioning rod 18 to rotate as a whole. The bent sheet metal part 4 is rotated with the center of the rotating hole 1901 as the rotation axis, so that the outer wall that was originally on the bottom side can be flipped to the side of the other grinding component 2 for polishing. The height of the magnetic plate 21 can also be adjusted according to the actual bent part to better adapt to the planar magnetic attraction requirements. The electric telescopic rod 20 is activated to drive the magnetic plate 21 to adjust.

[0037] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
