Pressure balancing device for automatic pipe blank polishing machine

Abstract

The invention provides a pressure balancing device for an automatic pipe blank polishing machine, belonging to the technical field of machining. The pressure balancing device for the automatic pipe blank polishing machine mainly comprises a fixed pedestal and an adjusting lead screw; the fixed pedestal is movably connected with the lower end of the adjusting lead screw; an adjuster for manually heightening a polishing abrasion wheel surface is arranged on the upper part of the adjusting lead screw, an adjuster for manually lowering the polishing abrasion wheel surface is arranged on the lower part of the adjusting lead screw, and a damping balancer for skipping a polishing abrasion wheel mainframe back and forth is arranged between the upper and the lower adjusters; and a connecting device of a polishing abrasion wheel mainframe pedestal is arranged on the middle part of the adjusting lead screw. The pressure balancing device can be used for continuously and automatically feeding, therefore, the yield reaches 8000 kg within 8 h, which is 10 times as large as that of a traditional polishing machine; and the invention has the advantages of solving the problem of large workload of grinding and maintaining hair cracks at the outside of a pipe blank, saving a large amount of manpower and greatly increasing the labor production efficiency.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and relates to a pressure balance device for an automatic tube blank polishing machine. Background technique [0002] The throwing plate and the motor of the traditional polishing machine are fixed on the platform. When the tube blank is polished, because the outer diameter of the tube blank is elliptical, the outer surface of the tube blank cannot be completely thrown to the surface. Sometimes it is difficult to pass through the place with a large outer diameter. If it is blocked, resources are wasted (the loss of the tube blank and the cost of polishing), and where the outer diameter is small, it cannot be thrown, and the polishing effect cannot be achieved. [0003] The speed of traditional polishing is not fast, and the output is only 800kg calculated according to 8 hours, and the labor efficiency is not high. Contents of the invention [0004] The present invention aims at th...

[0002] The throwing plate and the motor of the traditional polishing machine are fixed on the platform. When the tube blank is polished, because the outer diameter of the tube blank is elliptical, the outer surface of the tube blank cannot be completely thrown to the surface. Sometimes it is difficult to pass through the place with a large outer diameter. The steel pipe is thrown to the plate If it is blocked, resources are wasted (the loss of the tube blank and the cost of polishing), and where the outer diameter is small, it cannot be thrown and the polishing effect cannot be achieved.

[0003] The speed of traditional polishing is not fast, the output is only 800kg calculated in 8 hours, and the labor efficiency is not high
