Assembly equipment and method for steel ball type steering intermediate shaft

Abstract

The invention discloses assembly equipment and method for a steel ball type steering intermediate shaft. A servo motor component for height adjustment is arranged at the top of an assembly frame, a liftable joint fork clamping mechanism mounting frame body is arranged at one side of a frame body, the frame body is provided with a fixed joint fork clamping mechanism component, and the joint yoke part of a steel ball type steering intermediate shaft to be assembled is clamped through the mechanism component; the lower portion of a motor for applying the torque is connected with the center position of the fixed joint fork clamping mechanism component, and the motor for applying the torque is used for applying the torque to the steel ball type steering intermediate shaft to be assembled clamped by the fixed joint fork clamping mechanism component; and an angular clearance testing mechanism component is arranged on the lower portion of the joint fork clamping mechanism mounting frame body, and the steel ball type steering intermediate shaft to be assembled is clamped through the angular clearance testing mechanism component and an adaptive steel ball is selected to assemble the intermediate shaft. According to the assembly equipment and method, an angular clearance between a shaft and a pipe is effectively and accurately tested, and the optimum matching steel ball is selected to meet the assembly requirements of various steel ball type intermediate shaft assemblies.

Description

technical field [0001] The invention relates to the field of assembly of components, in particular to an assembly device and an assembly method applied to a steel ball type steering intermediate shaft. Background technique [0002] At present, one of the parts of the automobile steering system - the intermediate shaft is used as the transmission link connecting the steering column and the steering gear. The intermediate shaft transmits the torque and speed from the steering column to the steering gear. The intermediate shaft must have a strong Torsional rigidity and low running noise, and easy telescoping function. Therefore, its research and development and manufacturing are the key core technologies of major auto parts manufacturers. [0003] With the continuous development of the automobile industry, the requirements for the electric power steering system are gradually increasing during vehicle research and development, and the output torque that the system can provide i...

Problems solved by technology

[0004] According to the current investigation and analysis of the existing products on the market, the results show that the structure of spline type coating or injection coating under the existing technology is difficult to meet the requirements of high torque, so it is currently in the middle of developing the steel ball type. The intermediate shaft of this type of structure has obvious advantages in the application of high torque. However, due to the many differences in the steel ball structure on the market, there are problems such as high processing costs or too complicated structures that increase assembly The complexity leads to the problem that the efficiency of the assembly line is reduced
