Description
Technical field
The utility model relates to a kind of novel bearing pull-up, belongs to that Light Electrical product Axial parts is debug, maintenance field.
Background technology
Bearing is the parts being widely used in fixing in machinery, Light Electrical product Axial parts, is used for transmitter shaft or the motion of part and load on it.Debug at Axial parts, overhaul need dismounting bearing time, because bearing and axle, hole belong to transition or interference fit, during dismounting, often damage is caused to bearing, axle or dead eye, even makes bearing, axle or dead eye loss of function.Therefore, invent a kind of novel bearing pull-up to be necessary.
Summary of the invention
The utility model provides a kind of novel bearing pull-up, the bearing that can be widely used in machinery, Light Electrical product shaft components is debug and is dismantled, use this device when dismantling bearing, can ensure that the precision of shafting precision, bearing accuracy or installing hole is unaffected, thus guarantee systemic-function.This apparatus structure is dexterous, easy to use, be easy to carry.
The purpose of this utility model is achieved through the following technical solutions:
A kind of novel bearing pull-up, comprise screw rod, claw I, claw II, guide holder and clamping disk(-sc), clamping disk(-sc) is connected on screw rod by thread bush, and clamping disk(-sc) can be driven during bolt rotary to move up and down; Claw I, claw II symmetry are arranged on clamping disk(-sc) both sides, and claw I, claw II can rotate on clamping disk(-sc); Guide holder is connected on clamping disk(-sc) by thread bush, and is in above clamping disk(-sc); Described claw I, the upper end of claw II withstand on the lower surface of guide holder, and the upper end of claw I, claw II can along the oblique slip of the lower surface of guide holder.
Further, described clamping disk(-sc) both sides have vertical slot, and clamping disk(-sc) both sides have multiple locating hole one, and locating hole one runs through vertical slot; Claw I, claw II have multiple locating hole two in the longitudinal direction, and claw I, claw II are by being arranged in the vertical slot of clamping disk(-sc) through the bolt of corresponding locating hole one and locating hole two, and bolt is fixed by nut.
Further, the quantity of described locating hole one is 1 ~ 3.
Further, the quantity of described locating hole two is 1 ~ 3.
Further, described claw I, the upper end of claw II are provided with a slope, and guide holder lower end is an inverted cone surface, and the slope of claw I, claw II upper end is close to the inverted cone surface of guide holder lower end, and can slide along inverted cone surface.
Further, described screw tip is provided with rotating handle.
This device guiding seat profile adopts the conical surface, and its compact conformation, centering is good, and claw can be made accurately to clamp bearing outer ring.This device adopts screw rod to rise and pulls out, and bearing can take out by rotating screw bolt.Coordinated by different locating holes one and locating hole two, claw I can be made, claw II obtains different card distances and subtended angle, to adapt to the bearing of different size, so the adaptability of this bearing pull-up is good.
All parts of this guiding mechanism all adopt cheap and the steel plate easily purchased, round steel, etc. common material make, compact conformation, better function, precision are high, process industrial art performance is good, assembly technology is simple, Use Adjustment convenience, good reliability, the scope of application are wide, therefore have good economy and generalization.
