Abstract
The invention relates to a manufacturing method for preventing an inner component from getting out. According to the manufacturing method for preventing the inner component from getting out, a tripod universal joint, a three-column-groove shell and three ball rings are included, the three ball rings are distributed on three ball pins of the tripod universal joint correspondingly, and the tripod universal joint is installed inside roller paths of the three-column-groove shell. The manufacturing method comprises the steps that 1, rivet openings are added in roller path opening parts of the three-column-groove shell, the rivet openings are formed by riveting two rivet points on the two sides of each roller path opening part, and metal on the end surface of each roller path opening part is squeezed towards the center of the corresponding ball path, so that the metal is in interference fit with the ball rings of the tripod universal joint in the positions of the roller path opening parts; and 2, the tripod universal joint is pressed into the roller paths of the three-column-groove shell through a press machine during assembling, and then the tripod universal joint below the roller path opening parts is in clearance fit with the three-column-groove shell. The manufacturing method for preventing the inner component from getting out has the beneficial effect that the problem that the tripod universal joint is damaged and loses efficacy due to the fact that the tripod universal joint gets out of the roller paths of the three-column-groove shell during logistics transporting and in the assembling process of a main machine plant is solved.
Description
Technical field
The invention belongs to machining manufacture method technical field, particularly relate to the manufacture method that a kind of anti-inner assembly pulls.
Background technique
Existing internal spherical cage does not have anti-slip structure, and product is in logistics transportation process, and in main engine factory's assembly process, when lacking the protection to product, tripod universal joint pulls from housing raceway, very easily causes damage of product.
As shown in Figure 1, the ball 3 of tripod universal joint 1 is Spielpassung with the raceway of housing 2, after tripod universal joint 1 loads housing 2 raceway, both can be free to slide, and pull from housing 2 raceway because not having the spacing tripod universal joint 1 that can not prevent.The particularly product of some band spring 5 structures, after Product Assembly completes, under the effect of spring 5 elastic force, tripod universal joint 1 is pulled to housing 2 raceway oral area, is more prone to cause tripod universal joint 1 to be deviate from from housing 2 raceway.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and the manufacture method that a kind of anti-inner assembly pulls is provided, solve tripod universal joint in logistics transportation, in main engine factory's assembly process to deviate from from housing raceway, cause tripod universal joint to damage Problem of Failure.
The object of the invention is to have come by following technical solution, comprise tripod universal joint, housing, three balls, these three balls are distributed in three ball pins of tripod universal joint respectively, and this tripod universal joint is loaded in the raceway of housing; Its manufacture method step is:
1), riveting mouth is increased at the raceway oral area of housing, this riveting mouth is by each riveting in raceway oral area both sides two riveting points, by the metal of raceway oral area end face toward the extruding of alley center, thus form interference fit at the ball of raceway mouth position and tripod universal joint;
2), in assembling by press machine, tripod universal joint is pressed in housing raceway, the tripod universal joint now below raceway oral area and be Spielpassung between housing.
As preferably, described housing is provided with three raceway oral areas, each riveting in both sides two riveting points of each raceway oral area, and its two riveting points and two riveting points of another side are symmetric.
Beneficial effect of the present invention is: solve in logistics transportation, tripod universal joint is deviate from from housing raceway in main engine factory's assembly process, causes tripod universal joint to damage Problem of Failure; Be issued in the situation not affecting the displacement of movable joint pivot angle the function preventing from pulling, the manufacturing process simultaneously realized is simple.
Accompanying drawing explanation
Fig. 1 is that the master of existing internal spherical cage looks cross-sectional view.
Fig. 2 is the structural representation of housing of the present invention.
Label in accompanying drawing is respectively: 1, tripod universal joint; 2, housing; 3, ball; 4, riveting point; 5, spring; 21, raceway oral area.
Embodiment
Below in conjunction with accompanying drawing, detailed introduction is done to the present invention: as shown in accompanying drawing 1,2, the present invention includes tripod universal joint 1, housing 2, three balls 3, these three balls 3 are distributed in three ball pins of tripod universal joint 1 respectively, and this tripod universal joint 1 is loaded in the raceway of housing 2; Its manufacture method step is:
1), riveting mouth is increased at the raceway oral area 21 of housing 2, this riveting mouth is by each riveting in raceway oral area 21 both sides two riveting points 4, by the metal of raceway oral area 21 end face toward the extruding of alley center, thus interference fit can be formed at the ball 3 of raceway oral area 21 position and tripod universal joint 1; Because there is interference between the two at the ball 3 of raceway oral area 21 tripod universal joint 1 and the raceway of housing 2, can guarantee that tripod universal joint 1 can not pull from housing 2 raceway under the effect of 1000N pulling-out force;
2), by press machine, tripod universal joint 1 is pressed in housing 2 raceway in assembling, be now Spielpassung between the tripod universal joint 1 of raceway oral area less than 21 and housing 2, can guarantee to be free to slide between the two, meet product usage requirement.
Described housing 2 is provided with three raceway oral areas 21, each riveting in both sides two riveting points 4 of each raceway oral area 21, and its two riveting points 4 are symmetric with two riveting points 4 of another side.
Be understandable that, for a person skilled in the art, technological scheme of the present invention and inventive concept be equal to and replace or change the protection domain that all should belong to the claim appended by the present invention.
