Description
Technical field
The utility model relates to the top provision for disengagement of a kind of lathe, is applied to the dismounting of Hydraulic copying lathe tailstock, belongs to field of machining.
Background technology
Mechanical car's bed end needs to dismantle when the course of work or maintenance, existing Hydraulic copying lathe tailstock is hydraulic control, there is no top liftout attachment, traditional dismounting mode adopts nut dismounting, this dismounting mode not only wastes time and energy, and overstress is large to tailstock injury power, affects the service life of whole lathe, reduces lathe operating efficiency.
Summary of the invention
In view of the defect that above-mentioned technology exists, the purpose of this utility model there is provided the top provision for disengagement of a kind of lathe, and this device is applicable to the top dismounting of lathe afterbody, easy to operate, time saving and energy saving.
To achieve these goals, the technical scheme that the utility model adopts is: the top provision for disengagement of a kind of lathe, it is characterized in that comprising rotating shaft, described rotating shaft is provided with clockwise thread on the position rotating footstalk direction, the other end of rotating shaft is provided with anti-clockwise thread, rotate footstalk, threaded rotating disk, described threaded rotating disk is hollow ring, circle ring inner wall is provided with the screw thread matched with clockwise thread on rotating shaft, middle swivel nut, described middle swivel nut is hollow cylindrical structure, middle swivel nut side is provided with the screw thread matched with anti-clockwise thread on rotating shaft, circumferentially barrier block is provided with every 120 degree at middle swivel nut opposite side inwall 360 degree, on the outer wall of middle swivel nut side, be provided with pair of keys block simultaneously, outer hollow cover is connect in middle swivel nut outer race, described outer hollow cover is two ends breaking-out type sleeve, outside hollow sleeve inwall is provided with two key block chutes, inner core ring is provided with in middle swivel nut inside, described inner core ring inwall is provided with screw thread, on outer wall, circumferencial direction is provided with a barrier block every 120 degree, inner core ring is by internal whorl and lathe is top is fixed.
Between two described key blocks, line is 180 degree.
Between two described key block chutes, line is 180 degree.
Barrier block on described middle swivel nut inwall is consistent with the barrier block size on inner core ring outer wall.
The top provision for disengagement of described lathe, concrete connection and principle are: first threaded rotating disk is screwed in rotating shaft clockwise, being rotated counterclockwise by middle swivel nut is screwed on rotating shaft again, make to be provided with space between threaded rotating disk and middle swivel nut, then outer hollow cover is socketed in middle swivel nut by the key block on inwall key block chute and middle swivel nut outer wall peripheral, make outer hollow overlap side to contact with threaded rotating disk, by top for lathe fixing by being threaded on inner core ring, then inner core ring is put into middle swivel nut together with lathe is top, inner core ring is made to be connected in middle swivel nut after inner core ring is rotated 120 degree, outer hollow being overlapped the other end withstands on lathe, now rotate rotating shaft, in the middle of rotating shaft drives, swivel nut reversely rotates, thus drive the top counter motion screwed in inner core ring, extract top from tailstock.
The beneficial effects of the utility model are: this device is applicable to the top dismounting of lathe afterbody, easy to operate, time saving and energy saving, and avoid the overstress problem large to tailstock injury power, increase the service life of whole lathe, improve lathe operating efficiency.
