Pretreatment device for processing wood carving surface by adopting woodworking oilstone

Abstract

The invention discloses a pretreatment device for processing a wood carving surface by adopting a woodworking oilstone. The device comprises a workbench, a center plate is arranged on the upper side of the workbench, a rail rod is fixedly arranged on the central plate, and fixing devices for supporting wood on the front side and the rear side are arranged on the rail rod. The wood is supported onthe front side and the rear side and is clamped on the upper and lower side, so that the degree of freedom for guaranteeing rotation of wood is guaranteed, the upper and lower positions of the inclined plane structure are staggered at equal angles to be in sliding fit with a parallelogram pushing block, in the process that the pushing block moves up and down, the pushing block slides with the slope structure so as to rotate the wood at a fixed angle and conduct comprehensive grinding and polishing, in addition, a jacked valve body is adopted, the valve body makes contact and be communicated with the wood every time, soapy water put in is communicated, and it is guaranteed that the adsorption force between oilstone and the wood is proper.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a pretreatment device for processing wood carving surfaces by using woodworking oilstone. Background technique [0002] Natural whetstone can be used for grinding the wood surface before wood carving process. In the traditional grinding process, due to the high hardness of the whetstone itself, the self-sharpening is not good. In order to improve the grinding force, the through groove needs to be used in combination with abrasive paste, while the whetstone in woodworking is mostly soapy water. [0003] However, during the grinding and polishing process of woodworking oilstone, on the one hand, the amount of soapy water cannot be precisely controlled, which will cause excessive adsorption on the grinding surface, increase the grinding depth, and make it difficult to move the equipment. On the other hand, the rotation of the wood cannot Rotating at equal angles does not guarantee...

In the traditional grinding process, due to the high hardness of the whetstone itself, the self-sharpening is not good. In order to improve the grinding force, the through groove needs to be used in combination with abrasive paste, while the whetstone in woodworking is mostly soapy water.

[0003] However, during the grinding and polishing process of woodworking oilstone, on the one hand, the amount of soapy water cannot be precisely controlled, which will cause excessive adsorption on the grinding surface, increase the grinding depth, and make it difficult to move the equipment. On the other hand, the rotation of the wood cannot Rotation at equal angles does not guarantee a complete wood finish
