Description

Technical Field

[0001] This utility model relates to the field of wood clamping technology, specifically to an adjustable sanding and positioning clamp for wood processing. Background Technology

[0002] Timber processing refers to the process of transforming raw timber into finished products with certain value and uses through a series of technological processes. This industry covers the entire process from timber harvesting and transportation to the production of final products, including various stages such as log cutting, drying, planing, trimming, splicing, and finishing. In these stages, auxiliary clamps are often used to make the timber processing process simple, convenient, and easy.

[0003] A search revealed that invention patent CN111283828A discloses a wood clamping fixture with adjustable clamping area according to wood length. The fixture includes a housing with a working cavity inside. The working cavity contains an area adjustment component, which includes a sliding bracket slidably connected to the rear inner wall of the working cavity and main sliding clamping blocks symmetrically slidably connected to the lower end of the sliding bracket. This invention employs main and auxiliary sliding clamping blocks. By changing the distance between the left and right main sliding clamping blocks and the distance between the left and right auxiliary sliding clamping blocks, the clamping area can be changed, enabling the clamping of wood of different lengths. The invention also utilizes a sliding bracket and a first gear. The rotation of the first gear causes the sliding bracket to move downwards, thereby allowing the main and auxiliary sliding clamping blocks to clamp the wood. This achieves the clamping of wood of different lengths, improving work efficiency and ensuring smooth wood processing.

[0004] The invention described above can clamp wood of different lengths, but when it is necessary to change the sanding surface of the wood, the wood still needs to be refilled. Therefore, a rotatable and adjustable wood sanding positioning clamp is designed. Utility Model Content
