Description

Technical Field

[0001] This utility model relates to the field of metal parts processing technology, and in particular to a grinding device for processing sheet metal chassis parts. Background Technology

[0002] During the processing of sheet metal parts, in order to prevent oxidation and corrosion and extend the service life of the metal parts, protective paint is usually sprayed on the surface of the sheet metal parts. Before painting, it is necessary to remove grease and dirt from the surface of the metal parts, and the metal surface needs to be moderately polished to enhance the adhesion of the paint and remove oxides and rust. However, during the polishing process, the metal dust generated by the oxide scale and burrs on the metal surface will float in the air in the work area. If inhaled, it will seriously affect the health of the workers. In addition, the entire operation process relies heavily on the operator's work experience, which can easily lead to insufficient or excessive polishing, affecting the appearance after painting, and even generating residual stress, affecting the overall strength of the sheet metal parts.

[0019] Combined with appendix Figures 1-4 A grinding device for processing sheet metal parts of a chassis includes a support plate 1, support legs 2, a base plate 3, a fixing frame 6, a sliding bracket, a grinding machine 13, and a dust collection device. Support legs 2 are distributed on the lower end face of the support plate 1, and a base plate 3 is provided between each support leg 2, which is parallel to the support plate 1. Fixing frames 6 are provided at both ends of the support plate 1, and the fixing frames 6 fix the two ends of the metal plate to the upper end face of the support plate 1. Horizontally arranged guide rails 8 are symmetrically arranged on both sides of the support plate 1. Slider 9 is provided on both guide rails 8, and a sliding bracket is provided on both slider 9. The grinding machine 13 is installed on the sliding bracket and slides above the support plate 1 through the sliding bracket.

[0020] The bearing plate 1 has two horizontally arranged T-shaped connecting grooves 5 symmetrically arranged at both ends. One end of the connecting groove 5 passes through the side of the bearing plate 1. The fixing brackets 6 at both ends of the bearing plate 1 are set in the corresponding connecting grooves 5. The two fixing brackets 6 can be disassembled and installed in the connecting grooves 5, which facilitates the installation and laying of metal sheet metal parts.

[0021] The fixing frame 6 includes a fixing plate 14, a support rod 15, a connecting plate 17, a limiting rod 18, a lead screw 19, a knob 20, and a pressure plate 21. The fixing plate 14 is set in the connecting groove 5. Two support rods 15 are symmetrically arranged on the outer surface of the fixing plate 14. The support rods 15 have an arc-shaped structure. The upper end of the support rod 15 is provided with a horizontally arranged connecting plate 17. The lower part of the connecting plate 17 is provided with a parallel pressure plate 21. The upper end of the pressure plate 21 is symmetrically provided with two limiting rods 18. The upper ends of the two limiting rods 18 pass through the connecting plate 17 and are slidably connected to the connecting plate 17. The upper end of the pressure plate 21 is provided with a lead screw 19. The upper end of the lead screw 19 passes through the connecting plate 17 and is threadedly connected to the connecting plate 17. The upper end of the lead screw 19 is provided with a coaxially arranged knob 20. Rotating the knob 20 causes the lead screw 19 to rotate, which drives the pressure plate 21 to move up and down, so as to facilitate the fixation of the edge of the metal sheet below by the pressure plate 21, so as to keep the workpiece flat during the grinding process and improve the processing quality of the workpiece.

[0022] The outer surface of the fixing plate 14 is provided with a handle 16, which facilitates the assembly and disassembly of the fixing frame 6.

[0023] The sliding bracket includes an L-shaped plate 10, a connecting frame 11, and a sliding plate 12. The two sliders 9 are provided with symmetrically arranged L-shaped plates 10. The connecting frame 11 is provided between the two L-shaped plates 10. The sliding plate 12 is provided inside the connecting frame 11. The sliding plate 12 slides laterally along the connecting frame 11. While the sliding bracket moves laterally along the guide rail 8, the grinder 13 on the sliding plate 12 moves longitudinally along the connecting frame 11 to facilitate grinding the surface of the metal plate.

[0024] The lower end of the grinding machine 13 passes through the sliding plate 12, and the grinding machine 13 is threadedly connected to the sliding plate 12. The pressure generated between the grinding head of the grinding machine 13 and the workpiece is adjusted through the threaded connection, so that the metal workpiece is subjected to consistent force during the grinding process, and the situation of insufficient or excessive grinding of the workpiece surface is avoided.

[0025] The dust collection device includes a dust collection trough 7, a connecting pipe 22, a discharge pipe 23, a dust collection bag 24, a fan 25, and an air conveying pipe 26. The lower ends of both guide channels 4 are equipped with dust collection troughs 7 connected to them. A connecting pipe 22 is provided between the two dust collection troughs 7, with both ends of the connecting pipe 22 connected to the two dust collection troughs 7 respectively. A discharge pipe 23 is provided on the connecting pipe 22, and a dust collection bag 24 is provided at the lower end of the discharge pipe 23. An air conveying pipe 26 is provided on the side of the discharge pipe 23, with one end of the air conveying pipe 26 connected to... The feeding pipe 23 is connected, and the other end of the air supply pipe 26 is connected to the air outlet of the fan 25. The air outlet of the air supply pipe 26 faces the dust collection bag 24. The fan 25 is electrically connected to the external controller. The fan 25 is set on the base plate 3. The airflow generated by the fan 25 is directed towards the dust collection bag 24, which drives the air in the connecting pipe 22 and the feeding pipe 23 to flow into the dust collection bag 24, so that negative pressure is generated in the two dust collection tanks 7, which adsorbs and collects the metal powder and dust generated during grinding.

[0026] The embodiment describes a machine chassis sheet metal processing and grinding device. In use, the water-inlet sheet metal part is placed on top of the support plate 1, and then a fixing bracket 6 is installed at one end. Rotating the knob 20 causes the lead screw 19 to rotate, driving the pressure plate 21 to move up and down, facilitating the fixing of the metal sheet metal part's edge by the pressure plate 21. After flattening the metal sheet metal part, the other fixing bracket 6 is installed in the same way to ensure the workpiece remains flat during grinding, improving the workpiece's processing quality. Then, the grinding machine 13 is rotated, and the pressure generated between the grinding head and the workpiece is adjusted via a threaded connection, allowing for grinding... During the process, the metal workpiece is subjected to uniform force, avoiding insufficient or excessive grinding of the workpiece surface. During the grinding process, the sliding bracket moves laterally along the guide rail 8, and the grinding machine 13 on the sliding plate 12 moves longitudinally along the connecting frame 11, which facilitates grinding of the metal plate surface and makes it easier for workers to operate. During the grinding process, the airflow generated by the fan 25 is directed towards the dust collection bag 24, driving the air in the connecting pipe 22 and the feeding pipe 23 to flow into the dust collection bag 24, so that negative pressure is generated in the two dust collection tanks 7, which adsorbs and collects the metal powder and dust generated during grinding, preventing workers from inhaling them.
