Inner and outer circle grinding device for machining pipe

Abstract

The invention provides an inner and outer circle grinding device for machining a pipe. According to the device, the inner circle grinding and the outer circle grinding are combined on the same equipment, and the inner surface and the outer surface of the pipe can be respectively ground under one-time clamping, wherein the outer circle grinding part can polish the pipe with rusted or scratched surfaces, so that the manufacturing efficiency and the appearance quality of a finished product are not influenced in the process of manufacturing the pipe into the finished product; and the inner circlegrinding part can find scratches or defects on the inner surfaces of different positions at any time through an industrial camera. Through a connecting mechanism and a circuit arranged in an inner circle grinding main shaft, a grinding wheel can rotate at high speed under the drive of a high-speed motor, so that surface high-speed grinding is achieved, and grinding quality is guaranteed; and circumferential small sector grinding is achieved, and the problems of deep grooves, local overgrinding and the like caused by point grinding are effectively avoided, so that the grinding surface is smoothand continuous.

Description

technical field [0001] The invention belongs to the technical field of pipe material processing, and in particular relates to an inner and outer circle grinding device for processing pipe materials. Background technique [0002] Pipes are widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. However, the pipes are easy to rust after long-term storage, or the collision between steel pipes will cause scratches during long-distance transportation, which will have a certain impact on the next step of manufacturing and processing finished products, and will also affect the appearance quality of the finished products. Certain defects will ultimately affect the production efficiency of the finished product. For example, an aluminum alloy liner for a high-pressure gas cylinder with a pressure of 20-70 MPa is manufactured using a spinning or extrusion process. Since this typ...

Problems solved by technology

However, in the process of processing, the accumulation of extremely fine aluminum on the molding die will easily cause through-type scratches on the inner or outer surface, which must be dealt with in time, which requires the use of special grinding equipment to repair the inner and outer surfaces of aluminum alloy pipes Grinding

At present, there is no special grinding equipment for inner and outer circles, and traditional grinding machines cannot perform simultaneous grinding of inner and outer circles at the same time, and multiple clamping is required, resulting in long grinding process time; at the same time, the grinding efficiency of inner and outer circle grinding devices is low, and It is also easy to cause secondary scratches
