Eccentric shaft composite size detection tool clamp and detection method

Abstract

The invention discloses an eccentric shaft composite size detection tool clamp and a detection method. The tool clamp comprises an upper positioning tip, a lower positioning tip, a driving holding clamp, a spline angle detection device and a detection head, wherein an eccentric shaft is arranged between the upper positioning tip and the lower positioning tip for positioning, the driving holding clamp is arranged above the lower positioning tip and used for holding and clamping an eccentric shaft and driving the eccentric shaft to do circular motion, the spline angle detection device is arranged below the upper positioning tip and connected to the eccentric shaft in an engaged mode, and the detection head is used for measuring the composite size of the eccentric shaft. According to the toolclamp, all to-be-detected sizes can be detected by clamping once and unifying the detection reference, so the detection error is reduced, the detection algorithm is optimized, the detection time is reduced, and detection efficiency and detection accuracy are further improved.

Description

technical field [0001] The invention relates to the technical field of eccentric shaft detection, in particular to a tooling fixture and a detection method for compound size detection of eccentric shafts. Background technique [0002] The eccentric shaft is a key component in the RV reducer, which plays the role of transmitting the rotation of the planetary gear to the swing of the cycloidal wheel, so there is a high precision requirement for this part. Especially the following key dimensions: phase angle, deflection angle, and eccentricity. When the phase angle error is too large, the input shaft will interfere with the planetary gear, which is manifested by the noise of the reducer, the vibration during operation, and the reducer being stuck. The problem is that when the deflection angle and eccentricity error are too large, the movement of the cycloidal wheel will interfere with the needle roller, which manifests as problems such as vibration during the operation of the r...

Problems solved by technology

Various composite size inspections require multiple clamping and testing with corresponding testing equipment, which not only takes up a lot of equipment but also has low detection efficiency; multiple clamping and testing will not only prolong the detection time and reduce the detection efficiency, but each clamping There is a clamping error on the machine; every time you use different equipment, the error between the equipment will cause the error of the amount detection of the eccentric shaft, which will affect the accuracy of the detection result.
