A device for detecting runout of the inner end surface of the steering knuckle king pin hole

Abstract

The invention relates to the technical field of steering knuckles, and discloses a detection device for end face runout in a king pin hole of a steering knuckle, which includes a sensor, a detection component, and a bracket for making the sensor and the detection component come into contact. The detection component includes a shaft core, an induction screw and The adjustment structure is used to adjust the expansion and contraction of the induction screw. The cylindrical surface of the shaft core and the kingpin hole of the steering knuckle are a transitional fit. The induction screw is placed in the radial placement hole of the shaft core through the adjustment structure. One end of the shaft core is provided with a The rotating structure of the shaft core, the end surface of the other end of the shaft core corresponds to the sensing contact of the sensor. The present invention not only has a simple and reliable structure, but also has the advantages of high convenience in operations such as handling, storage, disassembly and use, and high safety.

Description

technical field [0001] The invention belongs to the technical field of steering knuckle detection, in particular to a device for detecting runout of the inner end surface of a king pin hole of a steering knuckle. Background technique [0002] The steering knuckle is one of the main parts on the steering axle of the car, which can make the car run stably and transmit the driving direction sensitively. The function of the steering knuckle is to bear the front load of the car, support and drive the front wheel to rotate around the kingpin to make the car turn. People in the industry all over the world attach great importance to its safety features, and fully understand that its safety features play a particularly important role in the processing of steering knuckles, and should run through to the control of the entire manufacturing process. Therefore, after the production and processing of the steering knuckle, it is necessary to test its space, angle, and hole position to ensu...

Problems solved by technology

The Chinese utility model patent with the authorized notification number CN207132871U discloses a steering knuckle runout detection device, which transmits the runout of the inner end surface of the kingpin hole of the steering knuckle to the weight, and then passes the angular displacement sensor connected to the weight Measuring whether the provocation amount of the inner end face of the steering knuckle is within a reasonable range reduces the testing cost to a certain extent, but the installation process of the device is complicated when the testing equipment is installed, the installation accuracy is high, and the use process is not convenient. The efficiency is low. At the same time, the device can only detect the steering knuckle of the same fixed model, and the versatility is poor
