Description

technical field [0001] The invention relates to the field of sensor production, in particular to equipment for the production of automobile wheel speed sensors. Background technique [0002] The wheel speed sensor is a sensor used to measure the speed of the car wheel. For modern cars, wheel speed information is essential, vehicle dynamic control system (VDC), automotive electronic stability program (ESP), anti-lock braking system ABS, automatic transmission control system, etc. need wheel speed information . The automobile wheel speed sensor is generally composed of a housing and an electronic counter. The housing is composed of a sensing head and a ring gear. The existing assembly method of the automobile wheel speed sensor is to weld the housing and the electronic counter together. After welding, the electronic The counter performs the bending operation. The shortcomings of the existing automobile wheel speed sensor production are: 1. The welding of the housing and the...

AI Technical Summary

Problems solved by technology

The shortcomings of the existing automobile wheel speed sensor production are: 1. The welding of the housing and the electronic counter, and the bending operation of the electronic counter are carried out separately, and the processing efficiency is low; 2. The loading and unloading of the housing and the electronic counter is slow, resulting in high production efficiency. Low; 3. The structure of the carrier holding the shell during processing is simple and cannot be accurately positioned. It is difficult to perform other operations on the shell in the carrier, which affects the accuracy of processing and leads to a low pass rate of the product; 4. Shell The connection with the electronic counter is of low firmness, which affects the qualified rate of the product; 5. When the shell is welded with the electronic counter, welding slag splashes easily damages the electronic counter, which affects the qualified rate of the product; Inspect the conditions that affect the product qualification rate, such as damaged electronic counters, that is, it is impossible to sort qualified and unqualified products, and the inspection needs to be followed by manual operations, which is time-consuming and laborious
