Full-automatic internal polishing machine for circular elbow pipes

Abstract

The invention discloses a full-automatic internal polishing machine for circular elbow pipes. The full-automatic internal polishing machine comprises a main motor, an internal polishing shaft, a polishing abrasive paper head and an elbow die. The main motor is arranged on a motor plate. The full-automatic internal polishing machine is characterized in that the main motor is connected with the internal polishing shaft, an arc-shaped die hole is formed in the elbow die, a cylinder is arranged on the elbow die, a stepper motor is arranged at the lower end of the elbow die and drives the elbow die to run along an arc track of the die hole, the elbow die and the polishing abrasive paper head are matched with each other to polish the inner wall of an elbow pipe, and a small motor is arranged at a side end of the main motor to drive the main motor to rotate. The full-automatic internal polishing machine has the advantages that the three motors are matched with one another, so that the polishing abrasive paper head can rotate circularly, the elbow die rotates along the arc track, the main motor rotates, the inside of the circular elbow pipe can be uniformly polished, the full-automatic internal polishing machine is high in polishing efficiency, low in noise and reliable in polishing quality, is labor-saving and can be widely applied to polishing insides of circular elbow pipes with various diameters, and the quantity of dust is low.

Description

technical field [0001] The invention relates to a polishing machine, in particular to a fully automatic internal polishing machine for elbow round tubes. Background technique [0002] Pipe polishing is an important process in the production process of pipe fittings. At present, processing and production plants have mechanical polishing methods for polishing straight pipe fittings, but for the polishing of elbow round pipes, there is no corresponding polishing equipment, and manual polishing can only be used. In this case, it takes more than ten minutes to polish an elbow, especially the internal polishing of the elbow, which is very troublesome, with high labor costs, low efficiency, and high power consumption. There will also be a lot of dust and a lot of noise, causing The processing environment is harsh. In addition, manual polishing is prone to uneven polishing, and the polishing quality is uneven. Contents of the invention [0003] On the basis of the above drawbacks...
