DETAILED DESCRIPTION

[0022] See also Figure 1-5 , the embodiments of the utility model are further described;

[0023] A sheet metal end surface grinding device comprises a workbench 1;

[0024] A support frame 2 is fixed to the side of the workbench 1, and a grinding assembly is installed on the support frame 2. The grinding assembly includes a driving member and a wire drawing sand belt 6. The wire drawing sand belt 6 is sleeved on the outside of the driving member, and the driving member is fixed on the support frame 2;

[0025] The sheet metal to be polished is positioned on the workbench 1 using a clamp, and the vertical end face of the sheet metal is made to fit the brushed abrasive belt 6 in the polishing assembly. When the driving part is running, the brushed abrasive belt 6 will be driven to move, thereby polishing the vertical end face of the sheet metal. Through the use of the workbench 1 and the polishing assembly, the sheet metal parts can be automatically polished in batches, which can reduce the workload of the staff.

[0026] A positioning assembly for vertically positioning the grinding end of the wire drawing abrasive belt 6 is installed on the workbench 1. The positioning assembly includes a positioning vertical plate 7, a locking member and a mounting plate 8. The positioning vertical plate 7 is vertically attached to the inner side of the grinding end of the wire drawing abrasive belt 6. The mounting plate 8 is fixed on the workbench 1. The locking member is installed between the vertical plate 7 and the mounting plate 8.

[0027] Before grinding the sheet metal, the positioning vertical plate 7 is vertically attached to the inner side of the grinding end of the brushed abrasive belt 6, and the locking piece is used to firmly position the adjusted positioning vertical plate 7 on the mounting plate 8, so that the grinding end of the brushed abrasive belt 6 can be continuously kept in a vertical state. In the later stage, the brushed abrasive belt 6 can grind the vertical end face of the sheet metal more accurately, the grinding effect is better, the grinding quality remains consistent, and the problem of inconvenient control of manual grinding quality is solved.

[0028] There are at least two locking members, including a threaded rod 9, a mounting block 13 and a nut 14. The threaded rod 9 is fixed on the positioning vertical plate 7. The mounting block 13 is sleeved on the threaded rod 9 through an opening. The nut 14 is threadedly connected to the threaded rod 9 and is close to the outer wall of the mounting block 13.

[0029] When installing and positioning the positioning vertical plate 7, the mounting block 13 is sleeved on the threaded rod 9, and then the nut 14 is tightened on the threaded rod 9, the mounting block 13 is positioned together with the positioning vertical plate 7, and then the positioning vertical plate 7 is moved to the inner side of the grinding end of the drawing sand belt 6, and finally the mounting plate 8 is fixed on the workbench 1. At this time, the positioning vertical plate 7 is arranged vertically (it has been measured when designing the workbench 1 and the positioning component), so that the drawing sand belt 6 attached to the positioning vertical plate 7 is also arranged vertically, so that the grinding end of the drawing sand belt 6 can be kept in a vertical state continuously. In the later stage, the drawing sand belt 6 is more accurate in grinding the vertical end face of the sheet metal, the grinding effect is better, and the grinding quality remains consistent, which solves the problem that the quality of manual grinding is difficult to control.

[0030] The locking member also includes a pre-tightening mechanism, which includes a fixed sleeve 10, a spring 11 and a movable sleeve 12. The movable sleeve 12 is slidably sleeved in the fixed sleeve 10. The fixed sleeve 10 and the movable sleeve 12 are both sleeved on the outside of the threaded rod 9. The fixed sleeve 10 is fixed on the positioning vertical plate 7, and the end of the movable sleeve 12 is fixed on the mounting block 13.

[0031] The fixed sleeve 10 and the movable sleeve 12 are provided to protect the spring 11, so as to prevent the spring 11 from being exposed to the outside and affecting its service life. Since the spring 11 in the pre-tightening mechanism has elastic force, the use of the pre-tightening mechanism enables the positioning vertical plate 7 and the wire drawing sand belt 6 to have a pre-tightening force, thereby eliminating the gap between the wire drawing sand belt 6 and the sheet metal part, enhancing the tightness of the wire drawing sand belt 6 and the sheet metal part, and facilitating the grinding of all vertical end faces of the sheet metal part, so that the grinding effect of the device is better.

[0032] The driving member includes a motor 3, a driving wheel 4 and a driven wheel 5. The driving wheel 4 and the driven wheel 5 are longitudinally distributed and are both rotatably connected to the support frame 2. The drawing sanding belt 6 is sleeved on the outside of the driving wheel 4 and the driven wheel 5. The motor 3 is fixed on the support frame 2, and the output end of the motor 3 is fixedly connected to one end of the driving wheel 4.

[0033] Specifically, when the driving part is working, the motor 3 is connected to an external power supply, and the motor 3 will drive the driving wheel 4 to rotate on the support frame 2, which can transmit the wire drawing sand belt 6, and the wire drawing sand belt 6 will drive the driven wheel 5 to rotate on the support frame 2, thereby prompting the wire drawing sand belt 6 to grind the vertical end surface of the sheet metal on the workbench 1.

[0034] A tensioning wheel 15 is mounted on the support frame 2, and the tensioning wheel 15 is in contact with the inner wall of the wire drawing abrasive belt 6;

[0035] Specifically, the tensioning wheel 15 is provided to adjust the tightness of the wire drawing abrasive belt 6 to ensure the grinding effect of the wire drawing abrasive belt 6 on the vertical end surface of the sheet metal part.
