A jig for assembling a steel ball guide rail type intermediate shaft of a steering system and an assembling method thereof

Abstract

The invention discloses a clamp used for assembling a steel ball guide rail type intermediate shaft of a steering system and an assembling method. The clamp comprises an assembling base arranged on a support platform of a support. An intermediate shaft assembling clamp assembly is arranged on a base guide rail of the assembling base and is controlled to be unfolded or folded by a general feeding hand wheel arranged on one side of the assembling base. The intermediate shaft assembling clamp assembly is used for clamping the to-be-assembled part of the steel ball guide rail type intermediate shaft to the center of the clamp assembly, steel balls are arranged between steel ball rails, positioned under the assistance of leaf springs, of the steel ball guide rail type intermediate shaft through the intermediate shaft assembling clamp assembly, a lower steering shaft and an upper steering shaft are connected in a sleeved manner to form the integral steel ball guide rail type intermediate shaft. According to the clamp used for assembling the steel ball guide rail type intermediate shaft of the steering system and the assembling method, the assembling requirement for the intermediate shaft of the steering system can be met, operation is easy, the assembling work hours are reduced, the assembling precision and efficiency of the intermediate shaft are improved, the clamp and the method are suitable for different types of steel ball guide rail type intermediate shaft products, universality is improved, and the trial manufacture cost of the products is greatly reduced.

Description

technical field [0001] The invention relates to an assembly tool, in particular to a clamping device used in the processing and assembly of a steel ball guide rail type intermediate shaft applied to an automobile steering system. Background technique [0002] At present, in the trial production and assembly process of the automobile steering system, manual trial production and assembly of the intermediate shaft is required. The traditional old-style intermediate shaft is mostly processed by spline type and injection molding. However, since the intermediate shaft is in sliding friction during operation, it is difficult to ensure a small sliding force and fit clearance. If you want to reduce the sliding The shift force, in addition to being related to the material of the old-style intermediate shaft, due to its processing technology and structural problems, the old-style intermediate shaft will lead to a larger fit clearance, which makes the steering system of the car noisy wh...

Problems solved by technology

[0005] In order to solve the structural problems of the steel ball guide rail type intermediate shaft in the prior art, it has high requirements for manual trial assembly, and it is difficult for ordinary operators to meet the assembly requirements, and the existing steering system intermediate shaft is manually assembled The tooling and fixture operation is cumbersome and inconvenient, the assembly time is long, the accuracy is poor, and the efficiency is low, which cannot meet the assembly requirements of the steel ball guide type intermediate shaft, resulting in high trial production costs and cannot meet the growing research and development of automobile steering systems. For the problem of trial production requirements, the present invention provides a steel ball guide rail type intermediate shaft assembly fixture and assembly method for the steering system. Through the redesigned assembly fixture structure and the assembly method using the assembly fixture, it can meet the requirements of the steering system. The assembly requirements of the shaft shorten the assembly time, improve the assembly accuracy and efficiency of the intermediate shaft, and the device part of the present invention is convenient to assemble and disassemble, easy to operate, and reduces the workload of the operator. In addition, the present invention can adjust the advance and retreat of the jaws Quantity and replacement of different parts make the present invention applicable to different types of steel ball guide type intermediate shaft products, which improves the versatility and greatly reduces the trial production cost of the product
