Abstract
The utility model provides a press machine provided with a positioning model. The press machine provided with the positioning model comprises an oil cylinder, and a press head is installed on the end portion of a piston rod of the oil cylinder. The press machine further comprises a positioning model, a positioning hole matched with a positioning end of a shaft to be pressed in shape is arranged on the positioning model, and a center line of the positioning hole and a center line of the piston rod are arranged in a collinear mode. The press machine provided with the positioning model enables the positioning hole on the positioning model and the piston rod of the oil cylinder to be collinear by means of the arrangement of the positioning model, avoids the defect that a bearing is pressed to be deflected, enables the stress loaded on the bearing to be uniform, and improves press mounting quality.
Description
Technical field
The utility model relates to Machining Technology, relates in particular to a kind of forcing press that has positioning clamping fixture.
Background technology
The working pressure machine is on axle during running in bearings, and is even in order to make shaft strength in press-fiting process, deflection not, the oil cylinder center line that requires forcing press with treat that last item holds and the center line of waiting to press workpiece on same straight line.Existing fit normally relies on operator's experience to carry out manual setting, and it is inefficiency not only, and also inaccuracy of the size that press-fits.
The utility model content
The utility model provides a kind of forcing press that has positioning clamping fixture, to solve defective of the prior art, increases work efficiency and press-fits precision.
The utility model provides a kind of forcing press that has positioning clamping fixture, comprises oil cylinder, and the piston rod end of said oil cylinder is provided with pressure head, and wherein, said forcing press also comprises:
Positioning clamping fixture, said positioning clamping fixture are provided with and treat the locating hole that the positioning end shape of last item is complementary, the centerline collineation setting of the center line of said locating hole and said piston rod.
The aforesaid forcing press that has positioning clamping fixture, wherein, preferably: said locating hole is concentric stepped hole, and each aperture of said concentric stepped hole respectively with the said corresponding coupling of each diameter of axle of multidiameter of treating last item.
The aforesaid forcing press that has positioning clamping fixture wherein, preferably, also comprises: horizontal table, said positioning clamping fixture are fixedly installed on the said horizontal table, and the center line of said locating hole is vertically to be provided with.
The forcing press that has positioning clamping fixture that the utility model provides through positioning clamping fixture is set, makes locating hole and oil cylinder piston bar conllinear on the positioning clamping fixture, has avoided bearing to be pressed the defective of deflection, makes shaft strength more even, has improved to press-fit quality.
Description of drawings
The press structure sketch map that has positioning clamping fixture that Fig. 1 provides for the utility model embodiment.
The forcing press working state schematic representation that has positioning clamping fixture that Fig. 2 provides for the utility model embodiment.
The specific embodiment
The press structure sketch map that has positioning clamping fixture that Fig. 1 provides for the utility model embodiment, the forcing press working state schematic representation that has positioning clamping fixture that Fig. 2 provides for the utility model embodiment.Please see figures.1.and.2 simultaneously; The utility model embodiment provides a kind of forcing press that has positioning clamping fixture, comprises oil cylinder 1, and the piston rod end of this oil cylinder 1 is provided with pressure head 2; Wherein, This forcing press also comprises: positioning clamping fixture 3, positioning clamping fixture 3 are provided with and treat the locating hole 4 that the positioning end shape of last item 6 is complementary, the centerline collineation setting of the center line of said locating hole 4 and said piston rod.
Before press-fiting, will treat that earlier last item 6 puts into the locating hole 4 of positioning clamping fixture 3, can mate each other owing to treat the positioning end of last item 6 and the shape of locating hole 4, can be positioned in the locating hole 4 so treat last item 6; Treating socket bearing 7 and axle sleeve 8 on the last item 6 successively; Open oil cylinder 1 then and press-fit because the piston rod of oil cylinder 1 and the centerline collineation of locating hole 4, and the coupling of treating last item 6 and locating hole 4 make treat last item 6 center line also the center line of the pressure head 3 on while and the piston rod be complementary; Avoided press-fiting the defective of deflection; Make stressed more evenly, the downward last items cover 8 of pressure head 3, axle sleeve 8 drive bearings 7 and come downwards to and be press-fit into place.
In practical application, treat that the positioning end of last item is the multidiameter shape, be concentric stepped hole so above-mentioned locating hole 4 is set, each aperture of the concentric stepped hole of institute respectively with the corresponding coupling of each diameter of axle of the multidiameter of treating last item 6.
Further, above-mentioned forcing press is that in the vertical direction press-fits bearing 7, and forcing press also comprises horizontal table 5, and positioning clamping fixture 3 is fixedly installed on the horizontal table 5, and the center line of locating hole 4 is vertically to be provided with.
The forcing press that has positioning clamping fixture that the utility model embodiment provides through positioning clamping fixture is set, makes locating hole and oil cylinder piston bar conllinear on the positioning clamping fixture, has avoided bearing to be pressed the defective of deflection, makes shaft strength more even, has improved to press-fit quality.
What should explain at last is: above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
