Method and equipment for processing inner and outer conical surfaces of conical ring of synchronizer

Abstract

The invention provides a method and equipment for processing inner and outer conical surfaces of a conical ring of a synchronizer. The processing method comprises the following steps of: 1) processing a long barrel-shaped rough blank into a single blank; 2) fixing the blank obtained in the step 1) on an inner conical surface clamp, and performing inner surface processing on the blank to obtain a crude product; and 3) fixing the crude product obtained in the step 2) on an outer conical surface clamp, and performing outer surface processing on the crude product to obtain a finished product. The processing equipment comprises the inner conical surface clamp and the outer conical surface clamp. The method and the equipment have the advantages that: the material is saved, the processing efficiency is improved, the equipment is saved, and the product quality is improved.

Description

technical field [0001] The invention belongs to the field of synchronizer auxiliary equipment processing technology and related equipment, and in particular relates to a method for processing the inner and outer tapered surfaces of a synchronizer cone ring and the processing equipment. Background technique [0002] The double-cone synchronizer cone ring of the synchronizer is a thin-walled part, which is easily deformed during processing, and the accuracy of the workpiece affects subsequent processing. In order to ensure its function, it is required during processing: the roundness of the inner and outer cone surfaces should be less than 0.1mm. [0003] Traditional processing technology: cut-off processing is adopted. The double-cone ring blank is barrel-shaped. The inner and outer cone surfaces are processed on the entire barrel-packed blank, and then the workpiece is cut off. After cutting, it needs to be processed by a grinding machine to ensure the size requirements and p...

Problems solved by technology

[0003] Traditional processing technology: cut-off processing is adopted. The double-cone ring blank is barrel-shaped. The inner and outer cone surfaces are processed on the entire barrel-packed blank, and then the workpiece is cut off. After cutting, it needs to be processed by a grinding machine to ensure the size requirements and parallelism of the workpiece. The process mainly has the following disadvantages: 1. The processing time is prolonged, the processing efficiency is low, and the workpiece is easy to fly out after cutting, causing the workpiece to ellipse and bump; 2. The roundness of the workpiece is unstable, and the outer cone surface of the workpiece is not easy to measure, and the workpiece is cut off Post-inspection, if it does not meet the process requirements, it cannot be repaired, it can only be scrapped, and waste products are easy to be generated when replacing the tool; 3. Waste of tools 4. The material utilization rate is too low, and the remaining material head of more than 10mm is wasted after processing
