Description

Technical Field

[0001] The present application relates to the field of metal processing, and in particular to a burr grinding device for metal processing. Background Art

[0002] Burrs refer to the rough edges formed by needles or carving knives engraving lines on the surface of metal plates in needle engraving and engraving. In the production process of metal aluminum plates, the aluminum plates need to be cut. After cutting, the outer wall of the aluminum plates will have burrs, so it is necessary to use a grinding wheel to grind the surrounding of the aluminum plates. The existing grinding devices do not have the function of fixing the workpiece, and generally the workpiece is fixed manually. This fixing method is not only time-consuming and labor-intensive, but also has poor stability of the workpiece during grinding, which affects the grinding effect.

[0003] At present, a Chinese patent with announcement number CN218696888U discloses a burr grinding device for metal processing with strong fixation, including a fixed frame, a workbench fixedly connected to the middle end position of the upper end surface of the fixed frame, a threaded hole is opened at the top of the workbench, an adaptive threaded rod is arranged in the threaded hole, a rotating handle is fixedly connected to the top of the threaded rod, a splint is rotatably connected to the bottom end of the threaded rod, a slide rail is fixedly installed on the inner side wall of the workbench, an adaptive slider is arranged on the slide rail, and the side wall of the splint is fixedly connected to the side wall of the slider.

[0004] By manually rotating the handle, the threaded rod drives the clamp to move up and down, so that the aluminum plate is clamped and fixed. In order to improve the stability of clamping and fixing, the placement surfaces of the clamp and the bottom of the workbench are both horizontal planes. When there are raised structures on the surface of some special-shaped aluminum plates, the aluminum plate may be shifted when the burrs are polished after the clamp is clamped, thereby reducing the overall stability of the clamp and having a certain impact on the overall polishing efficiency of the aluminum plate.

[0005] In view of the above-mentioned related technologies, the inventor believes that there is a defect that the clamping plate may cause position deviation when fixing the special-shaped aluminum plate. Therefore, a burr grinding device for metal processing is proposed to solve the above-mentioned problem. Utility Model Content

[0022] By placing the aluminum plate on the workbench 2, the two limit bodies 7 are clamped on the outer surface of the aluminum plate along with the movable part 6. When the limit column 10 abuts against the aluminum plate with irregular side, the movable limit body 7 pushes the limit column 10 to move along the inside of the fixed groove 8, and the limit columns 10 at different positions are embedded in the fixed groove 8 at different depths, so that multiple limit columns 10 limit and support the aluminum plate, and the fastening bolts 13 are rotated to push the movable block 12 to move along the inside of the groove 11, so that the movable block 12 is limited and squeezed on the upper surface of the limit column 10, and then the limit column 10 after the support is stabilized is limited and fixed, which reflects the limit clamping effect of multiple limit columns 10 on the special-shaped aluminum plate.

The bidirectional screw rod 4 and the threaded hole are adapted to each other. The top of the movable part 6 passes through the fixed inner cavity 3 and is fixedly connected to the lower bottom surface of the limit body 7.
