Abstract
The invention relates to a pressing rivet process of a sliding fork blanking cap. Before a rivet is pressed, a spherical surface in the middle of the blanking cap is pressed flatly in advance, the outer circle diameter of the blanking cap is enabled to be enlarged, and the blocking cap and a mounting hole of the blanking cap of a sliding fork form interference fit. The blanking cap is riveted in an entire ring on the periphery and sealed to form an entire ring of plane sealing structure. The pressing rivet process of the sliding fork blanking cap has the advantages that the mode of entire ring pressing rivet is used for replacing a traditional mode of four-point pressing rivet in the pressing rivet process of the sliding fork blanking cap, and meanwhile a rubber gasket is removed, products after being riveted are reliable in tightness and large in pull-out force, the demands of part assembly and using are satisfied, the failure rate of a transmission shaft assembly after sale is close to zero, and economical benefit is considerable.
Description
Technical field
The present invention relates to pressure-riveting process, is mainly a kind of pressure-riveting process of slip yoke blanking cover.
Background technology
The traditional method of slip yoke blanking cover pressure-riveting process is to adopt rubber sheet gasket to realize the products air tightness function, blanking cover adopts 4 riveted joints, press and only work to compress rubber blanket, the air-tightness of product realizes by rubber blanket, the shortcoming of this technique be to rivet rear blanking cover to deviate from power little, rubber blanket exists the possibility of distortion, the sealing reliability defectiveness in product final assemble and use procedure, the fault rate of slip yoke leakage of oil is high after sale, and the Aftermarket Claims loss is large.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and a kind of pressure-riveting process of slip yoke blanking cover is provided.
The objective of the invention is to complete by following technical solution, the pressure-riveting process of this slip yoke blanking cover, first flatten the middle sphere of blanking cover before pressing, the blanking cover outside diameter is increased, form interference fit with the blanking cover installing hole of slip yoke, on circumference, whole circle riveted joint blanking cover seals the plane sealing structure that forms whole circle.
Beneficial effect of the present invention is: the pressure-riveting process of slip yoke blanking cover adopts whole circle to press to substitute press at traditional 4, cancelled simultaneously rubber sheet gasket, after riveting, products air tightness is reliable, to deviate from power large, satisfy part general assembly and instructions for use, driving-shaft assembly fault rate after sale is bordering on 0, economic benefits.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the generalized section of whole circle riveted joint.
Reference numeral: slip yoke 1, blanking cover 2.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is done detailed introduction:
As shown in Fig. 1-2, the method that the pressure-riveting process of this slip yoke blanking cover adopts whole circle to press, first flatten the middle sphere of steel blanking cover 2 before pressing, blanking cover 2 outside diameters are increased, form interference fit with the blanking cover installing hole of slip yoke 1, improve the sealing property of blanking cover, on circumference, whole circle riveted joint blanking cover seals the plane sealing structure that forms whole circle, and high sealing property is arranged.Further prevented blanking cover gas leakage, reduced the fault rate that leakage of oil appears after sale in product, three guarantees claim rate greatly reduced.This pressure-riveting process has been cancelled rubber sheet gasket simultaneously, has eliminated the possibility of rubber sheet gasket generation distortion after the riveting, has increased blanking cover and has deviate from power, and reduced Assembly part quantity, has reduced manufacturing cost.
The present invention is not limited to above-mentioned embodiment, no matter do any variation on its shape or material formation, every employing structural design provided by the present invention is all a kind of distortion of the present invention, all should think within protection domain of the present invention.
Claims (1)
1. the pressure-riveting process of a slip yoke blanking cover, it is characterized in that: first flatten the middle sphere of blanking cover before pressing, the blanking cover outside diameter is increased, and with the blanking cover installing hole formation interference fit of slip yoke, on circumference, whole circle riveted joint blanking cover seals the plane sealing structure that forms whole circle.
