Development Of The Autatbtic Rumout Measurement Head Of Automobile Brake Discs

With the social and economic development, increasing demand for car, automobilemanufacturing enterprises have become an important pillar of China's nationaleconomic development. With the increase of automobile usage, people pay more andmore attention to the safety performance of the car braking system which is good or badis directly related to the personal safety of drivers and pedestrians, while the brake discis related to vehicle safety performance parts, so strict control of its quality is veryimportant. Car brake disc manufacturing process, the key quality parameters weredetected, which is an important technical means to control the quality of their products.Automotive brake disc has many geometric parameters, and the most importantpart is the side face run-out which needs to test online. But now use automotive brakedisc function of the detector is a single, relatively low degree of automation, partsquality of the product changes in the production process, can not be visually displayed,product quality can not control, so the existing testing instruments can not be meet theactual demand.The main topic was developed based on high-precision non-contact reflection laserdisplacement sensor, automotive brake disk vibration detection system, given thespecific software and hardware implementations. Detection speed up to0.24min/piece(including taking take the workpieces time), the detection accuracy up to0.003mm, thesystem can meet the needs of the round beating online testing of automotive brake discend.Round beating the end-line detector as a key device of the brake disc productionline, can be achieved by adjusting the mechanical part and set the relevant parameters,the measurement of the end of several varieties of automobile brake disc round beating,so this is a flexibledetector.The entire detection system from the industrial control computer,818L dataacquisition card, the composition of the control board730, a reflective laserdisplacement sensor, servo motor systems, mechanical and pneumatic systems andprofessional testing software. System through a combination of computer testingtechniques and pneumatic control technology as well as mechanical and electrical integration technology combining to form the end of the IPC PCI bus-based automobilebrake disc round beating detection system, sensor read value and the solenoid valvesand proximity switches control to meet the requirements of the circle beat detectionrequirements of real-time, high accuracy and high stability of the end of the car brakedisc production process to solve the deficiencies of the existing detection devices andimprove the level of production efficiency and quality control of the brake disc.
