Description
Technical field
The utility model relates to a kind of workpiece press-loading apparatus.
Background technology
Flourish along with science and technology, the paces of machinery industry are progressively accelerated, and press-loading process also becomes very powerful and exceedingly arrogant topic.Major requirement when press-fiting is: must not injuring part when press-fiting, should be steady during press-in, be pressed into part should accurately put in place, the axle press-fited or cover leading-in end should have suitable starting taper, but length must not be greater than 15% of length of fit, guiding oblique angle generally should not be greater than 10 °, solid shafting is pressed into blind hole, steam vent or groove should be had at suitable position, press-fit the matching surface of part apart from outside particular/special requirement, clean lubricant should be coated with when press-fiting, when being pressed into forcing press, should according to the material of part and fit dimension before press-in.
At present, in assembling process, mandrel perpendicularity is the key problem in technology press-fited in workpiece fabrication, press-fit in workpiece fabrication, because perpendicularity is entirely with operative employee's range estimation, the perpendicularity of mandrel is difficult to control accurately, there is pressure unbalance loading, produce to squeeze and hinder the Worker's Stadium, affect assembly quality.
Summary of the invention

Detailed description of the invention
Below with reference to accompanying drawing, the technical solution of the utility model is described in detail.
This device is provided with positioning guide hole on the piston rod pressure head of hydraulic means, aims at mandrel upper end and positions, effectively ensure perpendicularity when mandrel press-fits, thus improve the assembly quality of workpiece.
Specific embodiment is as follows:
As shown in Figure 1, a kind of workpiece press-loading apparatus, this device comprises hydraulic means, mandrel 6, bearing 7, workpiece 8, for the positioning guide hole of positioning core axle perpendicularity and the support of the whole perpendicular positioning process of support, described support comprises upper beam 1, the column 3 of foundation 2 and about two correspondences, described hydraulic means comprises the hydraulic cylinder 4 providing hydraulic pressure, conduit under fluid pressure and piston rod pressure head 5, described hydraulic cylinder 4 is connected by configuration pipeline 9 and obtains required hydraulic pressure from Hydraulic Station, described piston rod pressure head 5 is provided with positioning guide hole, the upper end that can be used for aiming at mandrel 6 ensures the perpendicularity of mandrel 6 when press-fiting, described bearing 7 is fixed on the interlude of mandrel 6, described mandrel 6 runs through the center of workpiece 8, described piston rod pressure head 5 press against mandrel makes bearing be pressed in the setting slot of workpiece 8.
During use, first bearing 7 and mandrel 6 Screw assembly good, in the setting slot of the lower end aligned workpiece 8 of bearing 7, its perpendicularity is determined in the location, upper end of the positioning guide hole aligning mandrel 6 of piston rod pressure head 5, at this moment hydraulic means carries out piston movement, being decided to be perpendicularity when pilot hole determination mandrel 6 press-fits and then exerting pressure to mandrel 6 of piston rod pressure head 5, is pressed into by bearing 7 in slot that workpiece 8 presets, workpiece 8 presses rear out of service, effectively raises the assembly quality of workpiece.
