Mechanical circular hole grinding tool

Abstract

The invention discloses a mechanical circular hole grinding tool which comprises a disc and bolts; the top of the disc is fixedly connected with a handle; transverse slots are formed in the bottom ofthe disc; the number of the transverse slots is four; long grooves communicating with the transverse slots are formed in the top of the disc; inner cavities of the transverse slots are connected withsliding blocks in a sliding manner; the bottoms of the sliding blocks are fixedly connected with clamping blocks; the bottoms of the clamping blocks extend to the exteriors of the transverse slots; the tops of the sliding grooves are fixedly connected with first threaded rods; the tops of the first threaded rods penetrate through the long grooves and extend to the exteriors of the long grooves; and the tops of the first threaded rods are sleeved with threaded pipes. According to the mechanical circular hole grinding tool, with the adoption of second threaded rods and the threaded pipes, a vertical rod can be fixed, and the distance between a cutter and the disc can be adjusted, so that the inner wall of a semicircular hole is ground conveniently, the grinding difficulty of the semicircularhole is lowered, the grinding precision is improved and people can use mechanical circular hole grinding tool conveniently.

Description

technical field [0001] The invention relates to the technical field of grinding tools, in particular to a mechanical circular hole grinding tool. Background technique [0002] Grinding workers are workers in the grinding and polishing process of machinery manufacturing, processing industry, mold industry, wood industry, leather industry, etc. The purpose of their work is to remove the burrs on the surface of the workpiece and make it smooth, so that it is easy to continue processing or reach the finished product. The tools used It is mainly grinders, grinding wheel grinders, etc. Smaller manual workshops also use angle grinders, which are manually operated with sandpaper. [0003] In order to improve the accuracy and work quality of the semi-circular cylinder, it is necessary to ream the inside of the semi-circular hole and grind it. Most people use a semi-circular file to grind the inner wall of the semi-circular cylinder by rubbing back and forth. There is no device for fi...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a mechanical round hole grinding tool, which has the advantages of being able to clamp semi-cylinders of different sizes, and solves the problem that there is no device for fixing the semi-cylinders on the file, which makes the grinding process cumbersome and complicated. Increased the difficulty of grinding and reduced the grinding accuracy of semicircular holes
