Description

Technical Field

[0002] The electric power steering system (EPS) is a new type of power steering device that uses an electric motor as a power source. Compared with the mechanical hydraulic power steering system and the electronic hydraulic power steering system widely used in traditional automobiles, the electric power steering system omits all hydraulic components, is lighter in weight, has more flexible layout, improves fuel economy and maneuverability, and is more suitable for new energy vehicles. It uses the power generated by the electric motor to assist the driver in steering assistance. Its composition is generally the same for different vehicles, although the structural components are different. It is generally composed of an electronic control unit, a torque (steering) sensor, an electric motor, a gear reducer, a mechanical steering gear, a vehicle speed sensor, and a power supply. The basic components include: an electric motor, a worm, a worm wheel, a torque sensor mechanism, a potentiometer, a motor connector, a torque sensor connector, an energy-absorbing sleeve, a steering wheel lock device, a switch bracket, a lower bracket, a vibration-damping gasket, etc. Among them, the worm is an important part of the system, and the tooth shape and surface roughness on the worm are key factors for the worm to work stably with other components. For the tooth shape and roughness of the worm, the commonly used process is to use rolling equipment to roll the surface of the worm to achieve good surface roughness and tooth shape. However, in the existing method, the parts to be processed are manually loaded and unloaded to complete the roll-forming of the tooth shape on the worm, which has low processing efficiency and low output, and cannot meet the production volume requirements; and it is necessary to manually confirm whether the teeth are in place. During this process, there will be tooth anomalies on the parts. Minor tooth anomalies will cause the parts to be crushed, and serious ones will cause the risk of collision and damage to the roller equipment. In addition, conventional processing methods cannot meet the needs of parts to be processed of different sizes. For short parts, manual loading and unloading is impossible; and for extra-long parts, the worm teeth are not in the center, and the parts swing greatly during rolling. Utility Model Content
