Description
Technical field
The utility model relates to auto parts and components assembling field, particularly a kind of motor case inner bearing press-loading apparatus.
Background technology
In modern industry manufacture, need a lot of little assembling links to combine together, as the motor assembling in automobile production, all need man-made assembly, but because people's assembling will exist deviation and efficiency, affect the overall production capacity output value, the key position when bearing of motor, the degree of depth that it is pressed into and perpendicularity directly determine the quality of finished product.
But at present, the design of motor case inner bearing is generally and axle mating surface and identical with casing mating surface, thereby dwindle at assembling process middle (center) bearing endoporus, motor shaft is embraced, and then may be caused empty load of motor, the problems such as load current increase, and then cause production qualification rate low, for addressing this problem, generally need to carry out secret control to bearing and casing, thereby but increase production and processing cost.
Therefore need a kind of new technical scheme to solve the problems referred to above.
Utility model content
Utility model object: the problem and shortage existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of motor case inner bearing press-loading apparatus.
Technical scheme: the utility model discloses a kind of motor case inner bearing press-loading apparatus, comprise and press-fit support, bearing, pad, casing, lower air cylinder, press-fit cylinder, seaming chuck, lower frock and lifting body, describedly press-fit support and be well word structure, the upper end of described seaming chuck with press-fit cylinder and be connected, this press-fits cylinder and press-fits described in being fixed on the upper end of internal stent, described lower air cylinder be fixed on press-fit the upper end of support and with press-fit cylinder and be connected, described lower frock is fixed on and press-fits internal stent lower end, its position is corresponding with seaming chuck position, this lower frock bottom is connected with described lifting body, this lifting body is fixed on and press-fits support lower end, described bearing inside is notch cuttype, this bearing coordinates with shaft clearance, the bearing adopting in the utility model coordinates with shaft clearance, in the time being pressed into casing, need not consider the distortion of bearing bore diameter, bearing bore diameter shrinks also can not embraced axle, also reduces the wear intensity between bearing and axle simultaneously, strengthens bearing service life.
Pad described in the utility model is positioned at this bearing top, and this pad, between bearing and casing, can effectively prevent from press-fiting in process, and casing deformation is excessive and cause damage.
As further optimization of the present utility model, bearing and casing interference fit.
As further optimization of the present utility model, the utility model also comprises pressure monitor, by omnidistance pressure monitor, when pressure exceeds or during lower than prescribed limit, appliance arrangement is reported to the police, and can distinguish fast and effectively non-defective unit and defective products, raising production and processing efficiency.
As further optimization of the present utility model, the utility model also comprises displacement transducer, by adopting displacement transducer can effectively find fast the mistake occurring in assembling process, has greatly improved yields.
Beneficial effect: the utility model compared with prior art, has the following advantages:
1, the utility model is by adopting notch cuttype bearing, and this bearing coordinates with shaft clearance, in the time being pressed into casing, need not consider the distortion of bearing bore diameter, bearing bore diameter shrinks also can not embraced axle, also reduces the wear intensity between bearing and axle simultaneously, strengthens bearing service life.
2, the utility model adopts and be provided with pad between bearing and casing, can effectively prevent from press-fiting in process, and casing deformation is excessive and cause damage, effectively reduces defective products quantity.
3, the utility model whole process using pressure monitor, when pressure exceeds or during lower than prescribed limit, appliance arrangement is reported to the police, and can fast and effeciently distinguish non-defective unit and defective products, improves production and processing efficiency.
4, the utility model, by adopting displacement transducer can effectively find fast the mistake occurring in assembling process, has improved yields greatly.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model bearing and casing assembly structure schematic diagram.
Detailed description of the invention
Further illustrate the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, bearing press-fitting device of the present utility model, comprise and press-fit support 1, bearing 7, casing 8, lower air cylinder 2, press-fit cylinder 3, seaming chuck 4, lower frock 5 and lifting body 6, the upper end of seaming chuck 4 of the present utility model with press-fit cylinder 3 and be connected, this press-fits cylinder 4 and is fixed on the upper end that press-fits support 1 inside, lower air cylinder 2 be fixed on press-fit the upper end of support 1 and with press-fit cylinder 3 and be connected, lower frock 5 of the present utility model is fixed on and press-fits support 1 interior lower end, corresponding with seaming chuck position 4, and its bottom is connected with lifting body 6, this lifting body 6 is fixed on and press-fits support 1 lower end.
As shown in Figure 2, bearing of the present utility model 7 inside are notch cuttype, bearing 7 and casing 8 interference fit, in the time packing casing 8 into, bearing 7 external diameter distortion are shunk, it is with position internal diameter also distortion contraction thereupon, the position that the utility model shrinks bearing 7 internal diameters is emptied, increase bearing 7 internal diameters, ensure packing in casing 8 processes, bearing 7 internal diameters shrink also can not embraced axle, i.e. the utility model bearing 7 and axle 10 matched in clearance, the utility model bearing 7 adopts high-performance oil-containing material, has good anti-wear performance.
