In order to solve the above problems, a car bridge engineering personnel has been fully verified, boldly reformed, and changed the traditional processing technology. The OMS-10 online measuring system is installed on the machining center, and the TP6C probe is used to measure the right angle before processing the main pin hole. The needle actually measures the center coordinate of the lock pin hole (see Fig. 4, Fig. 5, Fig. 6), and automatically calculates the center position of the king pin hole according to the central coordinate value of the lock pin hole, thereby ensuring the king pin hole and the lock pin hole. The accuracy of the spatial position between. Thanks to the OMS-10 online measuring system, the operator does not need to use other auxiliary methods to save a lot of auxiliary operation time and shorten the processing time, thereby improving the efficiency of the machine tool, improving the production efficiency and effectively reducing the production cost. . Now, the OMS-10 online measuring system is installed on several machining centers of a car bridge, which realizes the transition from rigid to flexible. The size of the machined workpiece is not limited, and the size and quantity can be produced and processed.

A car bridge commented on Hafeng Pioneer: Before the “right angle measurement”, the workshop relies on the long direct insertion of the locking pin hole and the V-shaped positioning on the V-shaped seat of the machine tool holder to control the locking pin hole and the main pin hole. The length dimension is 28±0.2mm, the positioning is not reliable when the workpiece is actually processed (the fixture often fails, the workpiece is not tight, sometimes the iron filings are trapped, etc.), and the company’s pride is solved by the pioneering efforts of China’s pride. Quasi-machining problems.

4 Conclusion

In the highly competitive manufacturing industry, the use of CNC machine tools is becoming more and more popular. How to improve the efficiency of machine tools, reduce the production cost of manufacturers, and improve the competitiveness of enterprises is the most important issue. Using the OMS series of online measurement systems on CNC machines can fundamentally solve this problem. The installation of the OMS series of online measurement systems is an effective means of improving quality control methods.
