Embodiment Construction

[0011] The processing method of the cylinder inner surface of the AGC servo cylinder of the present invention specifically includes the following steps.

[0012] (1) Clamp the cylinder of the AGC servo cylinder on the spindle of the lathe. When clamping, it is corrected according to the inner and outer circles, and the jaws are slightly loosened to prevent the cylinder from being deformed by force; the workpiece to be processed is before ultrasonic processing. Surface roughness Ra value and ultrasonic machining allowance should meet the requirements in Table 1 according to different materials.

[0013] Table 1

[0014] material Roughness requirement before processing (μm) Ultrasonic machining allowance (mm) carbon steel 1.6-6.3 0.01-0.04 cast iron, stainless steel 1.6-6.3 0.01-0.04

[0015] (2) Install the ultrasonic surface finishing device on the tool holder fixture of the lathe. When clamping, ensure that the tool of the ultrasonic surface fi...

Abstract

The invention relates to a method for machining an inner surface of a cylinder barrel of an AGC (automatic gain control) servo cylinder, and belongs to the technical field of metal cutting processing. The method comprises the steps: machining the inner surface of the cylinder barrel of the AGC servo cylinder by utilizing a turning lathe and an ultrasonic surface polishing device, and controlling the contact pressure between a cutter and the inner surface of the cylinder barrel of the AGC servo cylinder, the feeding speed of the cutter and the cylinder barrel rotation linear velocity of the AGC servo cylinder according to different materials. After the inner surface is processed, the surface smoothness is improved by three levels, the surface micro hardness is improved by 20 percent, and the surface fatigue resistance can be improved by 200 percent or more.

Description

technical field [0001] The invention belongs to the metal cutting processing technology, in particular to a processing method for the inner surface of a cylinder barrel of an AGC servo cylinder. Background technique [0002] The machining of the inner surface of the cylinder barrel of the AGC servo cylinder has high requirements on shape and position tolerances. According to the current machining process, the workpiece must be unloaded after the lathe machining is completed and then transferred to the grinding machine for surface machining. However, when it is transferred to a grinding machine for processing, the inner surface of the cylinder barrel of the AGC servo cylinder after it is clamped may not be consistent with the benchmark when the lathe is clamped, which will make it difficult for the surface processing tolerance to meet the predetermined requirements, seriously Affected the yield of the workpiece. Contents of the invention [0003] Aiming at the shortcomings...
