Polishing machine for polishing inner surface of elbow

Abstract

The invention discloses a polishing machine for polishing an inner surface of an elbow. The polishing machine comprises a rack, a numerical control slide platform, a motor, a flexible shaft, a bent sleeve, a bent sleeve fixed frame, a speed reducer, a rotary platform, a clamp and a polishing disc, wherein the numerical control slide platform and the speed reducer are fixed on the rack; the speed reducer is arranged on one side of the numerical control slide platform; the motor is arranged on the numerical control slide platform; the bent sleeve fixed frame is fixed on the numerical control slide platform; the bent sleeve is arranged on the bent sleeve fixed frame; one end of the flexible shaft is connected with the motor and the other end of the flexible shaft penetrates through the bent sleeve and is fixedly provided with the polishing disc; and the rotary platform is fixed on the speed reducer and the clamp is mounted on the rotary platform. With the adoption of the polishing machine disclosed by the invention, the inner surface of the elbow can be automatically polished and the polishing machine is relatively convenient and safe to use; when being used for polishing, the polishing machine only needs to enter from one end of the elbow, and the polishing time is short, so that the polishing efficiency is effectively improved; and meanwhile, directions of wiredrawing traces on the inner surface of the polished elbow are consistent and thus the elbow is relatively beautiful.

Description

technical field [0001] The invention relates to a polishing machine, in particular to a polishing machine for polishing the inner surface of an elbow. Background technique [0002] Elbows are a common connector, mainly used to change the direction of pipelines. Elbows are widely used in pipeline design in many fields. As the elbows are used in more and more fields, the requirements for the manufactured elbows are also getting higher and higher. Especially in food, biology, medical and other fields, there are extremely strict requirements for the smoothness of the inner and outer surfaces of elbows. Therefore, how to polish the inner surface of the elbow has become a special concern of many producers. At present, the existing polishing scheme is to polish the elbow on a straight-handled polishing machine manually. Due to the angle of the elbow, the polishing disc cannot enter the elbow from one direction of the elbow, and the inner surface of the elbow can be polished at on...

AI Technical Summary

Problems solved by technology

At present, the existing polishing scheme is to polish the elbow on a straight-handled polishing machine manually. Due to the angle of the elbow, the polishing disc cannot enter the elbow from one direction of the elbow, and the inner surface of the elbow can be polished at one time. , the polishing disc must enter from both sides of the elbow for welding seam grinding and overall polishing of the inner surface

This is not only dangerous, but also low in production efficiency. At the same time, the inside of the prepared elbow is not beautiful, and sometimes it cannot meet the requirements of food grade or medical products.
