摘要
近年来，汽车行业迅速发展，汽车的研发也一直在进步，其中，对汽车底盘的研发一直在进行，汽车转向系统是汽车底盘中的重要组成部分。它对于确保车辆的正常安全行驶以及驾驶员的操作的手感准确度有着重要的意义。其中，液压助力转向器是利用汽车在转向时液压油流动产生的液压差实现助力转向的转向器。在液压转向器加工过程中，液压阀的扭杆销加工十分重要，这一部分的精确度直接关系到在转向时能否提供准确的液压助力，以及在直线行驶时不提供助力，以免发生偏差，更有关于驾驶员在使用液压转向器转向时，能否准确的识别到驾驶员的转向意图，是确保车辆能按照驾驶员需求实现直线以及左右转向时提供相同助力的一项重要指标。本文结合书籍知识以及现场实习所了解的加工工艺，对现有国内的加工工艺缺陷进行改进，从而实现一台自动找正、打销以及复测的一体化打销机。

Abstract
In recent years, the automobile industry has developed rapidly, and the research and development of automobile hasbeen improving. Among them, the research and development of automobile chassis has been going on, and the automobile steering system is an important part of the chassis..It is of great significance to ensure the normal safety of the vehicle and the accuracy of the operation of the driver..In this case, the hydraulic steering is the steering wheel of the hydraulic differential that is generated by the hydraulic flow of the car at the turn of the steering. In the process of hydraulic steering gear, the torque and pin processing of hydraulic valve is very important. The accuracy of this part is directly related to whether it can provide accurate hydraulic power support during the steering, and not to provide the help when driving in a straight line, so as to avoid deviation. It is more about whether the driver can accurately identify the steering intention of the driver when using the hydraulic steering gear, which is an important indicator to ensure that the vehicle can provide the same power as the driver needs to realize the straight line and the left and right steering. This paper combines the knowledge of books and the process of field practice to improve the defects of the existing domestic processing technology, so as to realize an integrated marketing machine which can automatically realize automatic alignment, pin fixing and retesting.
