Gear broaching clamp for steering gear rack

Abstract

The invention belongs to the technical field of mechanical equipment, and particularly relates to a gear broaching clamp for a steering gear rack, which comprises an upper leading-in device, a lower positioning device, a jaw 1 device and a jaw 2 device, the upper guiding-in device is located at the upper end of the gear broaching clamp and comprises a clamping module, a detecting module and a flushing module. A vertically-through cylindrical pipeline is arranged in the clamping module and used for allowing a workpiece to pass through and clamping the workpiece. The detection module is used for detecting whether a workpiece enters the upper guide-in module or not; the flushing module is used for externally connecting an oil way and flushing a workpiece; the lower positioning device is located at the lower end of the gear broaching clamp and used for detecting the axial position of the workpiece. The first jaw device and the second jaw device are located between the upper guiding-in device and the lower positioning device, arranged on the left side and the right side correspondingly and used for being matched with each other to clamp a workpiece. The sensor can play a role in mistake proofing, damage to a mechanical structure is avoided, and the consistency of repeated positioning is guaranteed; the oil pipe can prevent the surface of the workpiece from generating pits and even causing size out-of-tolerance.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a pull-tooth clamp for a steering gear rack. Background technique [0002] The rack and pinion steering gear is based on the gear and rack transmission as the transmission mechanism, and is often used in the steering system of automobiles. Among them, the steering gear rack requires high meshing precision. Therefore, in batch processing, the requirements for dimensional accuracy, surface roughness and dimensional consistency are high. [0003] The existing steering gear racks are usually processed by tooth milling, which has the problems of low efficiency and poor finish, and the tooth tip crowning parameters of the processed steering gear racks cannot meet the requirements. Contents of the invention [0004] In order to solve the above problems, the present invention provides a pull-tooth clamp for a steering gear rack with high positioning accuracy ...
