Abstract

The invention discloses a steering engine gear rack precision value comprehensive detection device and test method. The device comprises a pedestal (1) which is provided with a workpiece place bench (2) for controlling and adjusting workpiece positions, and a meter base (3) for installing and supporting a measurer (4); the direction of the measuring meter hand of the measurer (4) is vertical to the axial direction of the support workpiece of the workpiece place bench (2); the pedestal (1) is provided with a guide sliding device; along the guide sliding device, the meter base (3) can drive the measurer (4) to move along a parallel axis direction. According to the invention, the test method combines a traditional standard measuring tool and a tool structure, and integrates the separate measurement of the circular runout and linearity of an elongated rod in a traditional measurement method into a same measurer; in a measuring process, clamping is finished once, precision index detection items of a gear rack are simultaneously measured, and measurement data accuracy and efficiency are guaranteed.

Description

technical field [0001] The invention belongs to the field of automobiles, and more specifically relates to a comprehensive detection device and a test method for the precision value of a steering gear rack. Background technique [0002] With the development of the automobile industry, people have higher and higher requirements for the handling and comfort of the vehicle. At present, the steering system of the car industry is equipped with relatively advanced hydraulic power steering gear or electronic power steering gear. A steering gear adopts an important part in the steering gear—the steering gear rack. [0003] Steering gear racks are the same as ordinary gear racks. They are slender rods. During its production and processing, its shape tolerance and product dimensional accuracy are difficult to control, but its quality will directly affect the steering gear overall. Compared with the driver, the steering system is an easy-to-perceive and safe part in the vehicle. If th...
