Abstract
The utility model provides a bearing pushing-out device which comprises four fixing plates. Each fixing plate is provided with a square-head lead screw, each square-head lead screw penetrates through each fixing plate through a threaded hole in each fixing plate, and the fixing plates are provided with connection parts connected with one another. The operating principle of thread drive is adopted for the bearing pushing-out device, the function of disassembling bearings flexibly is achieved, and the bearing pushing-out device has the advantages of being small in size, large in transferring moment, convenient to use, and the like.
Description
Technical field
The present invention relates to universal machine structure field, especially a kind of apical axis device.
Background technology
Disclosed a kind of shaft coupling Shaft drawer on the market, it comprises screw mandrel, screw thread chassis, pusher dog, and screw mandrel is through on the screw thread chassis by screw thread chassis intermediate thread, and the pusher dog hinge-coupled is on the screw thread chassis.Screw mandrel withstands on axial end during work, and pusher dog is held the shaft coupling outer face; The screw thread chassis is motionless, and rotary screw is extracted shaft coupling, and this Shaft drawer also can be used for pulling out the bearing that is enclosed within on the axle.Shaft coupling Shaft drawer with this structure, normal because position of bearings distance axis end face is too far away in actual use, pusher dog length can't be extracted bearing inadequately from axle, can only bearing be pounded out with implements such as hammers, destroy axle and bearing, thereby, be necessary to redesign a kind of device bearing flexibility from the axle is ejected, and do not damage axle and bearing.
Practical summary of the invention
The purpose of this practicality invention is to use screw thread transmission operation principle, a kind of bearing flexibility from the axle is ejected is provided and do not damage the apical axis device of axle and bearing.
The technical scheme of this practicality invention is achieved in that
A kind of apical axis device is provided, it is characterized in that: described apical axis device comprises four fixed heads, and every fixed head is provided with the square toes screw mandrel, and the square toes screw mandrel is through on the fixed head by silk hole on the fixed head, and described fixed head is provided with interconnective connector.
Advantage of the present utility model is: the apical axis device has adopted screw thread transmission operation principle, has played the effect of flexible dismounting bearing, and it is little to have a volume size, advantage such as carry-over moment is big, and is easy to use.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of this practicality invention.
The specific embodiment
Below in conjunction with accompanying drawing 1 embodiment of the present utility model is described:
Referring to Fig. 1, the apical axis device comprises four fixed heads 1, and every fixed head 1 is provided with square toes screw mandrel 2, and square toes screw mandrel 2 is through on the fixed head 1 by silk hole on the fixed head 1, and fixed head 1 is provided with interconnective connector 3.
The course of work: fixed head 1 is fixed on the axle by connector 3, and four square toes screw mandrels 2 withstand on the bearing face, rotates square toes screw mandrel 2, and screw mandrel 2 moves axially, and promotes bearing and axially moves along axle, and then bearing is slowly ejected from axle.
Though above shown the detailed embodiment of this practicality invention, apparent, those skilled in the art is under the prerequisite of this practicality invention, can carry out the part modifications and changes; The content of mentioning in description above and the accompanying drawing is the illustration of property as an illustration only, is not as to restriction of the present utility model, has the apical axis device of above-mentioned technical characterictic, all falls into this practical invention protection domain.
