Automatic detecting instrument for retaining ring check ring of constant velocity universal joint three-pivot shaft

Abstract

The invention provides an automatic detecting instrument for a retaining ring check ring of a constant velocity universal joint three-pivot shaft. The automatic detecting instrument comprises a machine rack, wherein a workpiece installing mandrel for installing a workpiece and a driving mechanism I for driving the workpiece installing mandrel to rotate axially and connected with the workpiece installing mandrel are arranged on the machine frame, wherein the workpiece installing mandrel is provided with a positioning structure for positioning the workpiece, a sensor assembly is arranged above the workpiece installing mandrel and provided with an annular portion and a sensor, and the sensor is located on the inner wall of the annular portion. A driving mechanism II for driving the sensor assembly to be vertically lifted so as to close to or away from the workpiece installing mandrel is arranged on the machine rack, and the workpiece on the workpiece installing mandrel finally extends into the annular portion of the sensor assembly in the process that the sensor assembly is close to the workpiece installing mandrel. An electrical control system is arranged on the machine rack, the driving mechanism I and the driving mechanism II are electrically connected with the electrical control system, and the sensor is in electrical or signal connection with the electrical control system.

Description

technical field [0001] The invention relates to an automatic tester for a three-pivot buckle and retaining ring of a constant velocity universal joint. Background technique [0002] The pivot constant velocity universal joint is a kind of telescopic constant velocity universal joint, which is mainly connected with the automobile gearbox (or differential), and is responsible for the key steps in the process of transmitting the torque from the engine to the drive shaft. Its unique structural design and excellent kinematics characteristics make it widely used. The pivot type constant velocity universal joint is mainly composed of three major parts: cup body, shaft hub and bearing installed on the shaft hub. The buckle set on the shaft hub to limit the movement and fall of the bearing is one of the important safety parts. In the existing production process plan of the pivotal constant velocity universal joint, the installation inspection of the buckle is mainly completed by the...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned existing pivotal constant velocity universal joint buckle inspection technical solution is completed under the fluorescent lamp, relying on the naked eye identification and pulling of the assembly operator (to be pulled three times), although the inspection of the missing assembly of the product buckle can be realized , but due to the characteristics of long-term repetitive work, the operator's eyesight and physical strength are greatly consumed, mental fatigue, and occupational diseases such as boring work are prone to occur, and the phenomenon of missed buckle products not being detected often occurs

Once this kind of defective pivot constant velocity universal joint products enter the market, not only the service life will be low, but also there will be certain safety hazards

In addition, the efficiency of this inspection scheme relying on the naked eye of the operator is very low, and multiple operators are required to complete the inspection of the buckle during production, and the labor cost is high
