Abstract
The invention relates to an assembly tooling device for a miniature bearing crown-type retainer. The device includes a seat sleeve, a lock sleeve, a shaft sleeve, a spring and an intermediate shaft. The seat sleeve and the lock sleeve are coaxial and the seat sleeve is located below the lock sleeve. The internal threads of the seat sleeve and the lock sleeve are in connection with the external thread of the shaft sleeve used for positioning of the retainer so as to fix the protruding edge at the lower end of the shaft sleeve. The intermediate shaft is placed in the mesopore of the seat sleeve and the shaft sleeve, the section of which is an inverted T shape. The outer side faces of the inverted T shoulder are in sliding fit with a seat sleeve inner pore, and the vertical shaft of the intermediate shaft is in sliding fit with the inner pore of the shaft sleeve. The spring is disposed inside the mesopore of the seat sleeve and at the inverted T shoulder bottom of the intermediate shaft. The vertical shaft tip section of the intermediate shaft is provided with steps so as to form positioning ring grooves with positioning shaft sleeve inner rings. The device of the invention has high efficiency and good assembly effect.
Description
Technical field
The present invention is applicable to the assembling of the micro rolling ball bearing crown type retainer of plastics or pressing sheet material.
Background technique
For micro rolling ball bearing, special micro rolling ball bearing particularly, in assembling crown type retainer, because retainer is especially little, is especially easily subject to external force and is out of shape., in when assembling, be originally all the manual retainer of placing, when assembling is pressed into steel ball, be very easy to occur assembly deflections or damage that the position of placing due to retainer and bearing decentraction cause crown type retainer, caused the off quality of bearing.And the underproof bearing of this assembling must again take apart and do over again, steel ball is wherein scrapped, and lasso must be done over again, then ressemble retainer, and the pilot process operation of doing over again has good multiple tracks, therefore cause man power and material's significant wastage, but also can have influence on the friendship phase of product.
For this situation, designed the assembly tooling that is suitable for micro rolling ball bearing crown type retainer.
Summary of the invention
The present invention seeks to: propose a kind of fitting device of assembling of miniature bearing crown type retainer, can improve efficiency of assembling, and distortion or damage while being unlikely to make the assembling of crown type retainer.
The assembly tooling device of miniature bearing crown type retainer, comprises cover for seat 5, lock tube 6, axle sleeve 7, spring 4 and jack shaft 2; Coaxial and the cover for seat of cover for seat 5, lock tube 6 is below lock tube, and the outside thread of the axle sleeve 7 of the internal thread connection retainer of cover for seat and lock tube location use, fixes the edge of axle sleeve lower end protrusion; It is inner with the mesopore of axle sleeve 7 that jack shaft 2 is placed on cover for seat 5, the cross section of jack shaft is the font of falling T, the shoulder of the falling T outer side surface of jack shaft is slidably matched at cover for seat 5 endoporus, and the vertical pivot of jack shaft is slidably matched at the endoporus of axle sleeve 7, and the mesopore inside of cover for seat 5 and the jack shaft shoulder of falling T bottom are provided with spring 4.The vertical pivot tip section of jack shaft is provided with step, and forms positioning ring groove between positioning shaft sleeve inner ring.
During assembling retainer, first retainer is placed on the positioning ring groove of positioning shaft sleeve and jack shaft formation, then the semi-finished product bearing after the Internal and external cycle of bearing and steel ball trap is placed in the Internal hole positioning district of jack shaft, steel ball is pushed respectively directly over the ball pocket of retainer, finally, to the Internal and external cycle of bearing vertical depression firmly simultaneously, retainer is pressed in bearing.
After pressure is removed, jack shaft is due to the promotion of spring, and band dynamic bearing rises, and directly from frock, takes out bearing, completes assembling.
Beneficial effect of the present invention is: use frock of the present invention can improve efficiency of assembling, distortion or damage in the time of can not making the assembling of crown type retainer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
The assembly tooling device of miniature bearing crown type retainer, comprises cover for seat 5, lock tube 6, axle sleeve 7, spring 4 and jack shaft 2; Cover for seat 5, lock tube 6 are located retainer by screw thread the edge lower end of the axle sleeve 7 of use protruding and are fixed; Jack shaft 2 is placed on the mesopore inside of cover for seat 5, and the cross section of jack shaft is the font of falling T, and the endoporus of the outer side surface of jack shaft and cover for seat 5 and axle sleeve 7 is slidably matched, and mesopore inside and the jack shaft bottom of cover for seat 5 are provided with spring 4.
Threading on cover for seat 5 one end cylindricals, with opening positioning seat hole on side end face; Reprocess a lock tube, one end machining internal thread, is used for coordinating with the outside thread of cover for seat; Process a retainer positioning shaft sleeve, be used for the cylindrical of locating retainer; Process a jack shaft, be used for positioning bearing endoporus and retainer endoporus, and can and cover for seat and retainer positioning shaft sleeve form cunning and join.The later frock of all component assembly as shown in Figure 1.After assembly, due to the thrust of spring, jack shaft and positioning shaft sleeve can be located to the cylindrical of crown type retainer and endoporus simultaneously simultaneously, reduce retainer and radially carry out play.
Cover for seat 5 and lock tube 6 are fixed as one retainer positioning shaft sleeve 7 by screw thread.Jack shaft 2 is placed on cover for seat 5 inside, forms sliding joining with cover for seat 5 and axle sleeve 7, by spring 4, jack shaft 2 is slided up and down.When jack shaft 2 slips peak and axle sleeve 7 form positioning ring grooves, be used for the cylindrical of retainer 3 and endoporus to position.1 is bearing.
During assembling, retainer 3 is put into positioning ring groove, then semi-finished product bearing 1 is placed in the Internal hole positioning district of jack shaft 2, steel ball is pushed respectively directly over the ball pocket of retainer, finally, to Internal and external cycle vertical depression firmly simultaneously, retainer is pressed in bearing.
After pressure is removed, jack shaft is due to the promotion of spring, and band dynamic bearing rises, and directly from frock, takes out bearing, completes assembling.
