Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: 1, compression bar；2, standard shaft；3, oil-free bushing；4, reciprocal axis；5, correction steel ball；6, sliding seat；7, gland；8,
Spring；9, hole retaining ring；41, pyramidal pits two；61, pyramidal pits one.
Specific embodiment
With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.
As shown in Figure 1, the deviation correcting device of the bearing press mounting of the present embodiment, the sliding seat 6 including being installed on pressure head top is living
It is equipped with groove in dynamic seat 6, standard shaft 2 is installed in groove, there are gap, standard shafts 2 between the circumferential side wall and groove inner wall of standard shaft 2
Reciprocal axis 4 is installed in inner cavity, forms the closure sky for accommodating correction steel ball 5 between reciprocal 4 bottom center of axis and groove floor center
Between, it is equipped with cylindrical cavity in reciprocal axis 4, is mounted therein with spring 8,8 bottom end of spring is fixed on cylindrical cavity bottom, and 8 top of spring is solid
Due in standard shaft 2, reciprocal axis 4 is slid axially by the oil-free bushing 3 being mounted in 2 inner cavity of standard shaft；4 outer circumferential walls of reciprocal axis
Bottom end is equipped with step, is equipped with the hole retaining ring 9 being fixed in 2 inner cavity of standard shaft on the step surface of step；It further include gland 7, pressure
Lid 7 is mounted at the notch of 6 groove of sliding seat, and the outer circumferential walls of standard shaft 2 are equipped with the shaft shoulder cooperated with gland 7；2 top of standard shaft
It is connect with the compression bar 1 of electric cylinders.
The closed space for accommodating correction steel ball 5, structure are formed between reciprocal 4 bottom center of axis and groove floor center
Are as follows: pyramidal pits 1 are equipped with including 6 inner groovy bottom center of sliding seat, reciprocal 4 bottom center of axis is equipped with and pyramidal pits one
61 symmetrical pyramidal pits 2 41, the section diamondwise in the space that pyramidal pits 1 and pyramidal pits 2 41 surround, diamond shape
Inscribe diameter of a circle is equal with the correction diameter of steel ball 5.
There are gap between the circumferential side wall of standard shaft 2 and the groove inner wall of sliding seat 6, the distance in gap is 2-3mm.
The implementation process of the utility model is as follows:
To arrive the gap 3mm since there are 2 between standard shaft 4 and sliding seat 6, when pressure head discontinuity, make sliding seat 6 relative to
Standard shaft 2 slides, and correction steel ball 5 deviates from the center in the space that pyramidal pits 1 and pyramidal pits 2 41 are formed, with
The sliding of correction steel ball 5 applies pressure to reciprocal axis 4, and the spring 8 in reciprocal axis 4 compresses, and reciprocal axis 4 is along oil-free bushing 3 in base
Upward sliding in axis 2, when the lateral force on pressure head disappears, spring 8 restores, and correction steel ball 5 restores to pyramidal pits 1 and cone
The center position in the space that shape pit 2 41 is formed, pedestal 2 and sliding seat 6 are to respective center return.
By the above process, solve the pressure head of bearing press-fitting device by when lateral force or unbalance stress due to rigid extruding
And the problem of deforming or wear, causing pressure head reduced service life, the utility model protect pressure head not become by rigidity extruding
Shape, while can guarantee when pressure head is pressed again with axis to be pressed or hole holding center to it, greatly improve the pressure of bearing
Fill precision and pressure head service life.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is within the protection scope of the utility model referring to claim, can make any type of modification.
