Description
Technical field
The utility model belongs to manufacturing technology equipment, particularly a kind of sliding bearing press-fitting tool.
Background technology
It is a key link of machinery assembling that sliding bearing press-fits, the quality that sliding bearing press-fits quality directly affects assembly quality and the service life of complete machine, existing sliding bearing press-fitting tool is open side type, bearing is along with frock presses downward in element mounting hole under pressure, once only to press-fit a set of bearing, cannot guarantee that two sleeves on same workpiece hold the uniformity of compression distance, and easily there is skewness in this press-fitting tool in press-fiting process, so require operating personnel's technical ability high, during pressing bearing, repeated work is many, and efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides that a kind of can to guarantee on same workpiece that two sleeves hold compression distance consistent, simple to operate, press-fits the sliding bearing press-fitting tool that skewness does not appear in rear bearing.
The technical scheme that the utility model technical solution problem adopts is: sliding bearing press-fitting tool comprises workpiece, bearing, soket head cap screw, be characterized in being equipped with in base intracavity locating piece, between locating piece and base, with soket head cap screw, be connected and fixed, on locating piece, the lower surface on umbrella edge is fitted in and floats on the inner convex platform of positioning sleeve lower end, unsteady positioning sleeve outer circumference surface lower end is installed in base intracavity, locating piece is left, back-moving spring is equipped with respectively between sitting in the unsteady positioning sleeve of right both sides and the end, guide pillar is housed above locating piece, between guide pillar and locating piece, with soket head cap screw, be connected and fixed, bearing is placed in respectively the endoporus of the positioning sleeve that floats, the lower surface of bearing is placed in respectively on the upper surface of guide pillar, workpiece is placed on the upper surface of the positioning sleeve that floats, the bearing mounting hole of workpiece corresponds respectively to the position of bearing, spacing by 8 word platforms of workpiece between workpiece and unsteady positioning sleeve.
The beneficial effects of the utility model are: many, the inefficient problems of repeated work when sliding bearing press-fitting tool has fundamentally solved original frock pressing bearing, guaranteed on same workpiece that two sleeves hold compression distance identical, and in the time of can avoiding bearing to be pressed into, produce skewness, simple to operate, reduced the technical ability requirement of operating personnel's operations.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, with embodiment, illustrate.
Fig. 1 is sliding bearing press-fitting tool structure cutaway view.
Fig. 2 is the top view of Fig. 1.
In figure, 1-workpiece; 2-bearing; The 3-positioning sleeve that floats; 4-guide pillar; 5-back-moving spring; 6-soket head cap screw; 7-locating piece; 8-base.
The specific embodiment
Embodiment, with reference to accompanying drawing 1,2, in base 8 inner chambers of sliding bearing press-fitting tool, locating piece 7 is housed, between locating piece 7 and base 8, with soket head cap screw 6, be connected and fixed, on locating piece 7, the lower surface on umbrella edge is fitted in and floats on positioning sleeve 3 lower end inner convex platforms, unsteady positioning sleeve 3 outer circumference surface lower ends are installed in base 8 inner chambers, between the unsteady positioning sleeve 3 of locating piece 7 arranged on left and right sides and base 8, back-moving spring 5 are housed.Locating piece 7 is equipped with guide pillar 4 above, between guide pillar 4 and locating piece 7, with soket head cap screw 6, is connected and fixed, and bearing 2 is placed in respectively the endoporus of the positioning sleeve 3 that floats, and the lower surface of bearing 2 is placed in respectively on the upper surface of guide pillar 4.Workpiece 1 is placed on the upper surface of the positioning sleeve 3 that floats, and the bearing mounting hole of workpiece 1 is the position of corresponding bearing 2 respectively, spacing by 8 word platforms of workpiece 1 between workpiece 1 and unsteady positioning sleeve 3.
The operation principle of sliding bearing press-fitting tool is: when pressing bearing 2, bearing 2 is put into respectively to the endoporus of the positioning sleeve 3 that floats, workpiece 1 is placed on the upper surface of the positioning sleeve 3 that floats, with 8 word platforms of workpiece 1, realize location, above workpiece 1, exert pressure, workpiece 1 moves downward, drive the positioning sleeve 3 that floats to move downward simultaneously, back-moving spring 5 is compressed, and guide pillar 4 spring bearings 2 upwards do relative motion, and bearing 2 is pressed in workpiece 1.Two guide pillar 4 end faces are through grinding, highly identical, guarantee that two bearing 2 compression distances are identical, and principal axis of pressing machine rises, and takes off workpiece 1, and positioning sleeve 3 homing under the effect of back-moving spring 5 of floating, repeats next operation.
