Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology for CNC milling machine housings, specifically a polishing device for the corners of CNC milling machine housing sheet metal. Background Technology

[0002] The sheet metal housing of a CNC milling machine is a protective structural component on the outside of the CNC milling machine. It is mainly made of sheet metal, steel or other metal materials through processes such as cutting, bending, welding and assembly. It is an indispensable part of the overall structure of the CNC milling machine. In order to assist in the stable polishing of the corners of the CNC milling machine housing sheet metal, a CNC milling machine housing sheet metal corner polishing device is needed.

[0003] Traditional CNC milling machine shell sheet metal corner polishing devices typically place the CNC milling machine shell sheet metal on a placement table and then use polishing components to polish the shell sheet metal. However, traditional devices are difficult to assist in the convenient adjustment and limiting of the shell sheet metal during use, which affects the stability of the shell sheet metal polishing. Furthermore, traditional devices are difficult to adjust conveniently according to the corner shape of the shell sheet metal, which also affects the stability of the shell sheet metal polishing.

An electric telescopic rod moves the clamping plate, which clamps and limits the shell sheet metal. The self-locking motor drives the positioning wheel to rotate, which in turn drives the placement plate to rotate. The placement plate then adjusts the angle of the shell sheet metal until it reaches the desired angle. Afterward, the self-locking motor is turned off, and a spring pushes the convex surface of the protruding rod against the concave surface of the positioning groove within the inner wall of the cylinder. This assists the positioning wheel in adjusting the angle of the placement plate, ensuring stable and limited polishing angle of the shell sheet metal.
