Cylinder boring device and method for processing cylinder using the device

Abstract

The invention discloses a cylinder barrel boring device and a method of using the device to process the cylinder barrel, wherein the cylinder barrel boring device comprises a guide rail and a boring head arranged on the guide rail; a boring cutter is arranged on the boring head; the boring head is in axial sliding fit with the guide rail through a power transmission device; and the guide rail is a cylindrical boring bar. According to the method of using the cylinder barrel boring device to process the cylinder barrel, the device is mounted on a lathe and directly positioned by the excircle of the cylinder barrel, thus eliminating the technological process of processing the exterior angles of the two ends of a reversed cylinder barrel in the traditional cylinder barrel boring; the excircle of the cylinder barrel and the gyration center of the boring bar are consistent; the axis of the inner hole of the bored cylinder barrel and the excircle of the cylinder barrel are concentric; even thickness of the wall of the processed cylinder barrel is realized in the aspect of processing technology, thereby ensuring the required strength of the cylinder barrel.

Description

technical field [0001] The invention relates to an auxiliary equipment for machining and a machining method using the equipment, in particular to a cylinder boring device and a cylinder machining method using the equipment. Background technique [0002] In recent years, hydraulic supports have become the supporting equipment for fully mechanized coal mining faces. With the continuous improvement of coal mines' requirements for coal recovery and the continuous progress of safe and efficient mining, hydraulic supports have developed towards large supporting forces and elevated types; hydraulic supports The column is the supporting component of the bracket, which bears all the supporting force of the hydraulic support, so the column cylinder develops to a large diameter and long cylinder. The inner diameter of the largest cylinder has developed to a diameter of Φ400 mm or more, and the length has reached about 2 meters. [0003] At present, the processing method of the inner ho...

Problems solved by technology

This processing technology is that the boring head 4 advances in a single cantilever in the cylinder 3. Due to the error in the wall thickness of the pipe material, its out-of-roundness is mainly concentrated on the inner hole, so the machining allowance of the inner hole is uneven, resulting in Uneven wall thickness after processing, resulting in a large increase in waste products

Most of the two outer corners on the inverted cylinder 3 adopt the method of chamfering the outer corners of the top inner hole. The essence is to position and process the inner hole allowance in the inner hole of the cylinder; , it will inevitably cause the inner hole of the processed cylinder to be inconsistent with the outer circle of the cylinder, resulting in uneven wall thickness after processing, which greatly weakens the original strength of the cylinder, and makes the cylinder inevitably fatal in terms of strength. defect
