Abstract
The invention discloses a kind of assembly method of power steering stgear, put first positioning sleeve at steering screw cylindrical; Put into retainer, moving on on the first positioning sleeve on the retainer position corresponding with steering screw straight raceway, put into fixed number steel ball; Slightly rock the first positioning sleeve and make steel ball fall into retainer, first positioning sleeve that moves up makes steel ball contact with the conical surface of straight raceway and sliding sleeve; The end of the steering valve core in steering screw is inserted in the second positioning sleeve and is moved down into steel ball and contacts with the conical surface, takes off the first positioning sleeve; Because the effect operator of the second positioning sleeve takes, steel ball, retainer and the second positioning sleeve are integrated mutually when the spool end of steering screw, in the time packing in valve body, when steel ball takes off the second positioning sleeve when steering screw race ring contacts on valve body, complete corresponding assembling. Simple and practical, efficient advantage that the present invention has.
Description
Technical field
The present invention relates to a kind of assembly method of power steering stgear.
Background technology
At present, in integrated traditional assembly method of power steering gear screw straight raceway, steel ball and retainer be: evenly coat lubricating grease at screw rod straight raceway; On straight raceway relevant position, put into retainer; In the hole of retainer, pack steel ball into; Finally screw rod and valve body assembling. In whole assembling, steel ball easily comes off, and process is loaded down with trivial details, and inefficiency particularly becomes bottleneck part in assembly line.
Summary of the invention
The object of the invention is in order to overcome above deficiency, a kind of assembly method of simple and practical, efficient power steering stgear is provided.
Object of the present invention is achieved through the following technical solutions: a kind of assembly method of power steering stgear, comprise base, and in base, be inserted with the mandrel of vertical setting, base is provided with two backing plates, and mandrel is located between two backing plates, and on mandrel, cover has seaming chuck.
A technological method for processing of pressing oilless bearing in steering gear housing, comprises the following steps:
A, put first positioning sleeve at steering screw cylindrical;
B, put into retainer, moving on on the first positioning sleeve on the retainer position corresponding with steering screw straight raceway, put into steel ball;
C, slightly rock the first positioning sleeve and make steel ball fall into retainer, first positioning sleeve that moves up makes steel ball contact with the conical surface of straight raceway and sliding sleeve;
The end of D, steering valve core in steering screw is inserted in the second positioning sleeve and is moved down into steel ball and contacts with the conical surface, takes off the first positioning sleeve;
E, because the effect operator of the second positioning sleeve takes, steel ball, retainer and the second positioning sleeve are integrated mutually when the spool end of steering screw, in the time packing in valve body, when steel ball takes off the second positioning sleeve when steering screw race ring contacts on valve body, complete corresponding assembling.
The present invention compared with prior art has the following advantages: the present invention can be at power steering stgear assembly shop execute-in-place, assembles simple, quick, practically, improves efficiency of assembling and product reliability.
Brief description of the drawings:
Fig. 1 is the structural representation of steps A;
Fig. 2 is the structural representation of step D;
Fig. 3 is the structural representation of step e;
Number in the figure: 1-steering screw, 2-the first positioning sleeve, 3-retainer, 4-steel ball, 5-steering valve core, 6-the second positioning sleeve.
Detailed description of the invention:
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
A kind of detailed description of the invention of the assembly method of power steering stgear of the present invention, comprises the following steps:
A, put first positioning sleeve 2 at steering screw 1 cylindrical;
B, put into retainer, moving on on the first positioning sleeve 2 on retainer 3 position corresponding with steering screw 1 straight raceway, put into steel ball 4;
C, slightly rock the first positioning sleeve 2 and make steel ball 4 fall into retainer 3, first positioning sleeve 2 that moves up makes steel ball 4 contact with the conical surface of straight raceway and sliding sleeve;
The end of D, steering valve core 5 in steering screw 1 is inserted in the second positioning sleeve 6 and is moved down into steel ball 4 and contacts with the conical surface, takes off the first positioning sleeve 2;
E, because the effect operator of the second positioning sleeve 6 takes, steel ball 4, retainer 3 and the second positioning sleeve 6 are integrated mutually when the spool end of steering screw, in the time packing in valve body, in the time that steel ball 4 contacts with 1 race ring of steering screw on valve body, take off the second positioning sleeve 6, complete corresponding assembling.
The present invention can be at power steering stgear assembly shop execute-in-place, assembles simple, quick, practically, improves efficiency of assembling and product reliability.
