Description

Technical Field

[0001] The utility model relates to the technical field of wood board chamfering positioning, in particular to a positioning device for wood board chamfering. Background Art

[0002] Chamfering a wooden board is to grind or cut the corners of the wooden board so that it no longer maintains the original right angle or sharp angle shape, but becomes smoother or rounder. This treatment method is not only beautiful, but also improves the safety and service life of the wooden board. In the existing patent application with application number CN202121978721.1, a wooden board chamfering device is proposed. Although the wooden board is placed on a rotating part, one side is positioned and one side is clamped inward through the positioning plate and clamping plate of the clamping part. The wooden board is fixed in the center of the rotating part, and then the rotating part drives the wooden board to rotate. During the rotation process, the four corners are polished by the grinding part. However, when the positioning plate, clamping plate and movable plate are clamped and fixed to the wooden board, if the wooden board is thin and the clamping force is large, it will be easy to clamp the wooden board, which will affect the normal use of the wooden board. If the clamping force is small, the wooden board is easy to move longitudinally when it is subjected to force, which will affect the chamfering of the wooden board, so it needs to be improved.
