Duplicate gear tooth surface angle detection equipment and using method thereof

Abstract

The invention discloses duplicate gear tooth surface angle detection equipment. The equipment comprises a detection part and an installation part. The detection part comprises a guide seat and detection mechanisms respectively located at the upper portion and the lower portion of the guide seat, installation holes for installing the detection mechanisms are formed in the upper portion and the lower portion of the guide seat, the detection mechanisms comprise pin shafts, measuring heads, sliding blocks and dial indicators, the sliding blocks are located in the installation holes and can move relative to the installation holes, the measuring heads are hinged to the sliding blocks through the pin shafts, the contact ends of the measuring heads are in contact with the tooth surface of a duplicate gear, and the probes of the dial indicators abut against the outer walls of the other ends of the measuring heads. The installation part comprises an extrusion part, liquid plastic and a positioning shaft, a liquid plastic cavity used for containing the liquid plastic is formed in the positioning shaft, and the extrusion part is adjusted to extrude the liquid plastic, so that the positioning shaft deforms and tensions the duplicate gear. The equipment is high in measurement precision.

Description

technical field [0001] The invention relates to the field of gear inspection tools, in particular to a device for detecting the angular direction of a tooth surface of a double gear and a method for using the same. Background technique [0002] In order to meet the assembly requirements of the switchboard, there is a type of intermediate double gear that requires the two gear working faces of every three double gear parts to have the same angular relationship (the error is not greater than 0.02mm, and the precision is high), so it needs to be assembled before assembly. Detect the actual value of the angular deviation of the two gear working surfaces of each double gear part, group and mark. However, the existing gear angular detection equipment has the following technical problems, which make it impossible to detect the angular relationship of the double gear tooth surface: 1. The gap between the double gear and the installation base is large during the positioning and insta...

Problems solved by technology

However, the existing gear angular detection equipment has the following technical problems, which make it impossible to detect the angular relationship of the double gear tooth surface: 1. The gap between the double gear and the installation base is large during the positioning and installation, resulting in a large gap during the entire detection process. The error is large; 2. Only one measuring head and one dial indicator are used for detection, and the lower or upper gears are positioned with pins and holes. The accuracy of the detected data is not enough, and the detection accuracy is greater than 0.02mm. Suitable for high-precision detection
