A pipe fitting inner wall grinding device

Abstract

The invention discloses a pipe fitting inner wall polishing device which comprises a base. One side of the top end of the base is provided with a first push rod motor. An output shaft of the first push rod motor is provided with a first slide block. The top end of the base is provided with a first slide groove. The first slide block is slidably mounted in the first slide groove and extends out of the first slide groove. A first servo motor is fixed to the end, located outside the first slide groove, of the first slide block through screws. An output shaft of the first servo motor is provided with a rotary disc. The end, away from the output shaft of the first servo motor, of the rotary disc is provided with a second slide groove. According to the pipe fitting inner wall polishing device, double cylindrical polishing heads are adopted to polish the inner wall of a pipe fitting, polishing efficiency is greatly improved, and by adjusting the positions of polishing motors on a circular disc, polishing of the polishing heads can be more accurately controlled, so that polishing precision is higher, and meanwhile, the polishing device can be suitable for pipe fittings of various diameters by arranging clamping blocks to be adjustable.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a grinding device for the inner wall of a pipe fitting. Background technique [0002] Grinding refers to grinding or rubbing the surface of objects to make it smooth and delicate. Pipe fittings are parts that connect pipes into pipelines. According to the connection method, they can be divided into four types: socket fittings, threaded fittings, flanged fittings and welded fittings. They are mostly used with pipes. Made of the same material, there are elbows (elbows), flanges, tees, four-way pipes and reducers, etc. The elbow is used for the turning of the pipe; the flange is used to connect the pipe to the pipe. Parts, connected to the pipe end, the three-way pipe is used for the place where three pipes gather; the four-way pipe is used for the place where four pipes gather; With the continuous improvement of various industries, the manufacturing precision of various pipe fitt...

[0002] Grinding refers to grinding or rubbing the surface of objects to make it smooth and delicate. Pipe fittings are parts that connect pipes into pipelines. According to the connection method, they can be divided into four types: socket fittings, threaded fittings, flanged fittings and welded fittings. They are mostly used with pipes. Made of the same material, there are elbows (elbows), flanges, tees, four-way pipes and reducers, etc. The elbow is used for the turning of the pipe; the flange is used to connect the pipe to the pipe. Parts, connected to the pipe end, the three-way pipe is used for the place where three pipes gather; the four-way pipe is used for the place where four pipes gather; With the continuous improvement of various industries, the manufacturing precision of various pipe fittings is getting higher and higher. Therefore, after the pipe fittings are formed, there will still be many defects on the inner wall of the pipe fittings. These defects need to be polished carefully. At present, the inner wall of pipe fittings is basically polished It is still manually polished bit by bit. This grinding method not only consumes manpower, but also has extremely low grinding efficiency and poor grinding accuracy. At present, the manual grinding method is far from the demand for the quantitative production of pipe fittings in factories. It cannot keep up with the production demand, and manual grinding also greatly increases the cost of pipe fittings production. In today's highly intelligent world, this high-cost and low-volume production mode can no longer adapt to the development of productivity. How to solve this problem is also a challenge for the current Some manufacturers have brought a lot of trouble
