Pull rod type tooth jump inspection tool

Abstract

The invention relates to a gear shaft part tooth jump detection tool in the field of machine manufacturing, in particular to a pull rod type tooth jump detection tool. The structure comprises a measuring head, an inner pull rod, an outer sleeve rod, a spring, a spring positioning key, a locking nut, a dial indicator fixing sleeve, a dial indicator, a handle, a frame body, a locking screw, a connecting bolt and a support. According to the working mode, the tooth jump detection function is achieved through relative movement of the inner pull rod and the outer sleeve rod. The outer sleeve rod, the support and the frame body serve as a fixed body; a measuring head is arranged at the front end of the inner pull rod, a handle is arranged at the rear end of the inner pull rod, the measuring head retreats out of a gear groove by pulling the handle, the workpiece is rotated, the handle is released, the measuring head enters the next gear groove through the elastic force of an internal spring, and the purpose of detecting circumferential tooth jump is achieved. According to the invention, the tooth jump of various gear shafts can be conveniently and rapidly inspected on a machine tool, and then the process of correcting the central hole of the gear shaft is executed. The tool has the characteristics of quick operation, accurate inspection, time saving and great improvement of the production efficiency.

Description

Technical field: [0001] The invention relates to a tool for detecting tooth jump of gear shaft parts in the field of machinery manufacturing, in particular to a pull-rod type tooth jump detection tool, which has wide promotion prospects in the field of gear processing. Background technique: [0002] All kinds of gear shafts are subjected to carburizing and quenching heat treatment process after rough milling in the early stage. Due to the release of internal stress and deformation, the gears will jump, so the working steps of repairing and researching the center hole must be carried out to ensure the subsequent finishing, fine grinding and other processes. The technology requires precision. The process of repairing and researching the center hole must first inspect the beating deformation of the gear after heat treatment, determine the amount of circumferential deformation, and then carry out the repairing work. Due to the large production volume and variety of products, us...

Problems solved by technology

Due to the large production volume and variety of products, using a special gear tester to test each product will increase the heavy burden of working time, equipment loss, etc., and seriously hinder production efficiency. Therefore, a convenient and quick tie rod that can be used directly on the machine tool is needed. Type tooth jump inspection tool to solve the above production bottleneck problem
