Pipe fitting inner wall grinding device for machine manufacturing

Abstract

The invention provides a pipe fitting inner wall grinding device for machine manufacturing. The pipe fitting inner wall grinding device for the machine manufacturing comprises a base, a grinding device body and a fixing device; the grinding device body comprises a supporting plate fixedly connected with the base, a first telescopic rod rotatably connected with the supporting plate, a plurality ofsecond telescopic rods fixedly connected with the first telescopic rod, and grinding blocks fixedly connected with the second telescopic rods; wherein a first cavity is arranged in the first telescopic rod; second cavities are arranged in the second telescopic rods; third cavities are arranged in the grinding blocks; the first cavity is communicated with the second cavities, and the second cavities are communicated with the third cavities. The pipe fitting inner wall grinding device provided by the invention has the beneficial effects that through the arranged fixing device, the purpose of horizontally fixing a pipe fitting can be achieved; and through the arrangement of the grinding device body, the purpose of grinding the inner wall of a fixed pipe fitting can be achieved.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, in particular to a device for grinding the inner wall of pipe fittings for mechanical manufacturing. Background technique [0002] Hardware pipe fittings are made of metal and are closed around the surrounding, with both ends sealed or open pipe structures. They are widely used in many fields. In most application scenarios, the inner and outer walls of hardware pipes need to maintain a certain degree of smoothness or ensure no Rust, so it is necessary to use the corresponding grinding device to grind the pipe fittings. However, the existing grinding device can only grind the inner wall of a specific pipe fitting, and cannot grind the inner walls of pipe fittings with different pipe diameters. Contents of the invention [0003] The object of the present invention is to provide a grinding device for the inner wall of a pipe fitting used in mechanical manufacturing in order to ove...
