A processing technology for processing cylinder blank of hydraulic cylinder

Abstract

The invention relates to a device and a method for processing a cylinder barrel blank of a hydraulic cylinder. The device comprises a table, power heads, numerical control cutters and two V-shaped blocks. The V-shaped blocks are parallelly disposed at the center of the table. The numerical control cutters are connected to the table and arranged on the same sides of the V-shaped blocks. The power heads are connected to the table and arranged at the front-and-back ends of the V-shaped blocks. Power head conical plates are arranged on the power heads. Boring cutters are mounted on the power head conical plates. The method includes the steps of boring the end surface of the cylinder barrel blank of the hydraulic cylinder; chamfering an inner angle of the cylinder barrel blank of the hydraulic cylinder; chamfering an outer angle of the cylinder barrel blank of the hydraulic cylinder; and, with the chamfered outer angle as a positioning standard, processing an inner hole in the hydraulic cylinder barrel on a deep-hole boring mill to achieve allowance complementation between the excircle surface and the inner hole of the cylinder barrel blank of the hydraulic cylinder. The device and the method have the advantages of simple structure of the device, operational convenience, simplicity of the method, and production efficiency and product quality increased by fit between the device and the method.

Description

technical field [0001] The invention relates to a device and processing technology for processing hydraulic cylinder cylinder blanks, in particular to a device for processing hydraulic cylinder cylinder blanks with eccentric inner holes and outer circles and the processing for realizing automatic mutual borrowing of blank margins craft. Background technique [0002] At present, most of the domestic hydraulic cylinders on the market are not concentric with the inner hole and the outer circle. The concentricity requirements of the hydraulic cylinder cannot be guaranteed by using traditional processing devices and processing techniques, resulting in high waste when processing domestic cylinders. The efficiency is low, and the economic benefit is low. If foreign cylinders are used, the cost will be higher. [0003] The traditional process of processing the hydraulic cylinder barrel is as follows: first clamp one end of the cylinder barrel on a lathe, position the end face of th...
