Description

Technical Field

[0001] The utility model relates to the field of automobiles, in particular to an input shaft inspection device for an automobile steering system. Background Art

[0002] Cars are a modern means of transportation. With the improvement of living standards, cars have long been part of thousands of households.

[0003] The steering system is an important part of the car. The steering system can be used to change or maintain the direction of the car. The steering gear is the core component of the steering system. It is responsible for amplifying and decelerating the torque applied by the driver on the steering wheel, and then transmitting it to the wheels through the steering rocker arm, steering straight tie rod and other components, so that the wheels deflect and thus realize the steering of the vehicle.

[0004] The input shaft is set between the steering wheel and the steering gear to transmit the driver's rotation to the steering gear. The input shaft is an important connecting component of the steering gear to support steering. The input shaft is usually used in the chassis steering gear actuator. The input shaft is a moving component with frequent movements and high technical requirements.

[0005] When the car is turning, the shaft spline plays a role in transmitting torque, preventing the input shaft and parts from rotating relative to each other, ensuring synchronization and stability during the working process, and automatically positioning the relative position between the input shaft and parts. The quality of shaft spline processing directly affects the life, reliability and comfort of the input shaft. The angle accuracy of the input shaft spline phase angle is strictly required. When the input shaft is milling the shaft spline, it is easy to machine the wrong teeth because the shaft spline is missing teeth, and the shaft spline and the small hole on the outer diameter of the other end of the input shaft have phase angle requirements, so the processing requirements of the milling shaft spline are very high.

[0006] At present, the input shaft can usually be inspected by a three-coordinate measuring machine. However, it takes a long time to measure the input shaft with a three-coordinate measuring machine. At the same time, the three-coordinate measuring machine needs to be on standby before the measurement result comes out, which easily causes waste of manpower and material resources and is difficult to meet the requirements of energy saving and cost reduction.
