Device for detecting run-out of flange of automobile rear axle main reducing gear component

Abstract

The invention relates to a detection device for the flange runout of the rear axle main reducer assembly of an automobile, which is characterized in that it includes a detection installation module, a notch monitoring module, an end face detection module, a drive module, a frame module and a control module; the machine The frame module is used to install the detection and installation module, the drive module and the control module; the detection and installation module is used to install the notch monitoring module and the end face detection module, the fulcrum of the detection and installation module is hinged on the frame module, and one end is fixed on the On the frame module, the other end is fixedly installed with a notch monitoring module and an end face detection module, and the notch monitoring module and the end face detection module are driven by the motion of the detection installation module to be connected with the convex end of the detected automobile rear axle main reducer assembly. edge separation or contact. The beneficial effect of the present invention is that it is more convenient to record the position of the maximum runout of the flange end face runout and notch runout, and to better locate the two.

Description

technical field [0001] The invention belongs to the field of quality detection of auto parts, and in particular relates to a runout amount detection device for the runout of the flange of the rear axle main reducer of the automobile and the runout of the seam. Background technique [0002] The driving axle of the car is at the end of the transmission system, and its basic function is to increase the torque transmitted from the transmission shaft or directly from the transmission, distribute the torque to the left and right driving wheels, and make the left and right driving wheels have the driving force of the car. The differential function required by kinematics; at the same time, the drive axle also bears the vertical force, longitudinal force and lateral force acting between the road surface and the frame or compartment. [0003] The main reducer assembly of the rear axle of the car is one of the main assembly structures in the drive axle of the car. It is the most import...

Problems solved by technology

[0005] During the processing, due to the influence of technology and various processing errors, the end face of the flange 91 may be uneven, and the circular shape of the stopper of the flange 91 may be irregular

In the installation process, there will also be a certain error. The shaft of the driving bevel gear 93 has a slight inclination in the mounting hole, so that the flange 91 has a slight inclination, and it is also easy to affect the rotation of the transmission shaft and the flange 91 and the flange 91. The driving bevel gear 93 does not rotate concentrically, resulting in unstable meshing between the driving bevel gear 93 and the driven hypoid gear 95, resulting in high noise during rotation, reduced transmission efficiency, shortened working life of the main reducer, and easy to cause vehicle safety accidents

[0006] Therefore, after assembling the rear axle final drive assembly, it is necessary to detect the motion of the rear axle final drive assembly. It is necessary to ensure that the flange 91 of the rear axle final drive assembly is in the direction of the seam and the end face. In the safe range during the working process, it is an important task in automobile production to detect the movement of the flange 91 of the assembled automobile rear axle final drive assembly, but there is no corresponding special-purpose automobile rear axle assembly.
