Problems solved by technology

Due to the small size of the tiny parts, it is not easy to clamp and fix during processing, and it is easy to appear the phenomenon of rounding and eccentricity of the hole after finishing processing, which will cause the parts to be scrapped.
In addition, only based on the experience of the operator, the consistency of the rounding depth of the hole after finishing is poor, which is far greater than the requirement that the consistency is within 0.02mm, and it is difficult to meet the performance requirements

Abstract

The invention belongs to the technical field of mechanical processing, and in particular relates to a device and a method for finishing the orifice of tiny parts. During the processing of the processing device, the device is installed on the punching machine tool, and the device includes a positioning base, a pressure rod, a limit ruler, a limit module, a fixing screw, a limit snap ring, a dial indicator stand, and a dial indicator, The tiny parts to be processed are put into the flat-bottomed holes of the positioning base, and the pressing rod is driven by the main shaft of the punching machine to squeeze the steel balls to realize the finishing processing of the holes. During processing, rough positioning is carried out through the limit device of the stamping machine, and then the accurate positioning of the stroke of the pressing rod is achieved through the dial indicator to ensure the consistency of the hole after finishing. The invention effectively solves the problems of low efficiency and unstable quality during the finishing of the small parts to be processed, and is intuitive and accurate.

Description

Technical field: [0001] The invention belongs to the technical field of mechanical processing, and particularly relates to a device and a method for finishing the orifice of a small part to be processed. Background technique: [0002] Small parts (total length < 2.5mm, maximum outer diameter < 3mm) end face small holes (diameter < 0.6mm) have extremely high requirements on the quality and consistency of orifice finishing. After finishing, the rounding depth of the orifice directly determines the product quality. Sealing performance and response time, the rounding depth of the orifice after finishing is required to be within the range of 0.15±0.01mm to meet the actual use requirements. [0003] Traditional processing method: a punching head is installed on the main shaft of the punching machine, and the punching head squeezes the steel ball to finish the small holes on the end face of the small parts. The operator judges the movement stroke of the punching head based...
