Embodiment Construction

[0021] This embodiment is a thin-walled elongated cylindrical batch production processing tool.

[0022] In the present embodiment, the processed workpiece is a 30CrMnSiA thin-walled slender cylinder with an aspect ratio of 1900 / 125=15.2. The outer diameter of the workpiece is 125mm, and the inner diameter is 117mm. The total length of the cylinder is 1900mm. The ratio of the outer diameter to the wall thickness It is 125 / 2=62.5. The cylinder is formed by spinning. It is necessary to machine the annular belts of the two ends of the cylinder, wherein the axial length of the annular belt at one end is 60mm, and the axial length of the annular belt at the other end is 120mm, and the coaxiality of the annular belts at both ends is required to be 0.08; 2. Processing The ends of the cylinder. Since the cylinder has a large length-to-diameter ratio and high dimensional accuracy, it is necessary to effectively control product deformation and ensure processing efficiency.

Abstract

A tool for processing a cylindrical workpiece comprises a mandrel, a snap spring, a pressure ring and a plug, wherein the snap spring sleeves the outer circumference surface of one end of the mandrel, and is fixedly connected with the mandrel through a fixing hole in the end surface of a small-diameter end of the mandrel. The plug is sleeved in the middle of the mandrel, and a large-aperture end of the plug is adjacent to the snap spring. The snap spring sleeves the outer circumference surface of the mandrel, and is located in an inner hole in one end of the snap spring. When the tool is used to process a cylindrical slender thin-walled workpiece, the clamping for cylindrical turning and radial facing can be finished at one step, the time for injecting gypsum is reduced, the clamping frequency and the assisting time are reduced, the processing efficiency is improved, and the tool meets the requirements of batch production. Meanwhile, the tool is light in structural weight, one person can finish the mounting of the tool, operation personnel are reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the machinery manufacturing industry, and relates to a processing tool for cylindrical thin-walled parts. Background technique [0002] The length-to-diameter ratio of thin-walled slender cylindrical parts reaches or exceeds 5:1, the wall thickness is thin, and the rigidity is poor. It is easily deformed by factors such as cutting heat, cutting force, gravity, and vibration during turning. It is a difficult-to-process product. . The processing of such products requires the aid of clamping fixtures. The tooling introduced in the current public information is used for single-piece or small-batch product processing. This kind of tooling requires too much auxiliary time when used. In the patent 201010537337.8 "A processing method and processing "Equipment" discloses a processing tool for a slender cylinder. The two ends of the tool are connected to the cylinder and 12 pressing blocks are connected by screws. The cylindrical workp...
