Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of sheet metal processing technology, specifically to a sheet metal chamfering machine. Background Technology
[0002] Sheet metal refers to flat, rectangular building material panels made to standard sizes. It is used in the construction industry as components for walls, ceilings, or floors, and often refers to metal sheets that are forged, rolled, or cast.
[0003] Board materials are widely used in the construction industry, including furniture manufacturing. Before use, they typically require beveling. However, current beveling methods usually involve workers attaching a grinding disc to an angle grinder, holding the board with one hand, and slowly moving the grinder along the board with the other. This is cumbersome, makes it difficult to control the beveling effect, and results in an inconvenient and inefficient process. Therefore, it is necessary to propose an improvement to solve these technical problems.
[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0010] Furthermore, a second threaded hole is provided at the bottom of the fixed guide sleeve, and a second locking screw is installed in the second threaded hole. Tightening the second locking screw can achieve the limiting and fixing of the movable table.
[0011] Furthermore, the bottom perimeter of the fixed tabletop and the bottom sides of the movable tabletop are each provided with support legs, and the bottom of the support legs are respectively equipped with casters.
[0012] Furthermore, two inverted T-shaped sliding grooves are provided on the front and rear sides of the top of the fixed tabletop, and two T-shaped sliding strips are provided on the front and rear sides of the bottom of the limiting guide plate. The two T-shaped sliding strips at the bottom of the limiting guide plate are slidably installed in the two inverted T-shaped sliding grooves on the top of the fixed tabletop.
[0013] Furthermore, the limiting guide plate is provided with a plurality of first threaded holes, and a first locking screw is installed in the first threaded hole. Tightening the first locking screw can achieve the limiting and fixing of the limiting guide plate.

[0016] 3. Beneficial effects:
[0017] Compared with the prior art, the technical solution provided by this utility model has the following advantages:
[0018] This utility model is reasonably designed. Before grinding the plate, the extension length of the first and second telescopic elements can be adjusted according to the size, width, and thickness of the plate to adjust the grinding disc to a suitable position. Then, the motor is turned on to make the grinding disc rotate, and the plate is placed on the fixed table, with one end of the plate abutting against the side of the limiting guide plate. Then, the plate is slowly pushed, and the grinding disc can be used to chamfer the edge of the plate. Its overall structure is simple and ingenious. For plates of larger or smaller sizes, a larger distance can be adjusted by moving the movable table. The L-shaped rod can also be height adjusted according to the needs of use.
