The utility model discloses a further technical scheme is: the positioning V-shaped block seat is made of 45 steel, and a U-shaped through groove is formed below the positioning V-shaped block seat; the installation is convenient, chip removal and cutting fluid flow are realized, and during the processing, the shaft is horizontally placed on the V-shaped inclined plane of the V-shaped block so as to realize the positioning of the circular shaft in the x direction and the z direction; in consideration of the hardness of the V-shaped inclined plane and the requirement of certain wear resistance, the V-shaped inclined plane is subjected to surface quenching treatment.

The utility model discloses still further technical scheme is: the limiting T-shaped block assembly is composed of a limiting support and a limiting bolt, the limiting bolt is installed at the equal-height position of the limiting support and the center of the part to be machined, the Y-axis direction of the shaft to be machined is located through the limiting bolt, and the screw is locked through a nut after the position of the bolt is adjusted, so that the Y-axis direction of the shaft to be machined is repeatedly located.

The utility model discloses still further technical scheme is: the clamping device consists of a supporting rod, a pressing plate and a nut, the supporting rod and the nut are respectively arranged on two sides of the positioning V-shaped block, and the pressing plate is arranged between the two supporting rods.

Compared with the prior art, the utility model has the following characteristics:

the utility model discloses a hole of above drilling frock processing has the position precision height, and frock simple structure installs convenient operation, and manufacturing cost is low, and the product percent of pass is high, advantages such as production efficiency height provide for the production and processing of like product reference and refer to, have extensive popularization and application and worth in the same trade.

The detailed structure of the present invention will be further described with reference to the accompanying drawings and the detailed description.
