Patent 1: applicant: Huang Liwen, application number: 200520058445.1, the applying date: 2005-05-23; The Pneumatic tailstock of wood-turning machine, especially wood-turning machine.Comprise thimble seat and thimble, thimble seat is fixedly connected with the body of lathe bed, and thimble and thimble seat are slidably connected, and it is characterized in that: be provided with the cylinder that cylinder body is fixedly connected with thimble seat, the piston rod of described cylinder connects with thimble.The beneficial effects of the utility model are, simple in structure, adopt air cylinder driven thimble top tight workpiece, and labour intensity greatly reduces, and is swift in motion, and pressure is stable, hold out against reliable.This patent is simple pneumatic means, can not manually operate the distance that regulates thimble, thereby the parts of processing are had to limitation.
Utility model content
The utility model provides a kind of lathe pneumatic jacking device, and object is in order better to adjust the pressure of different size processed product, and it is stable to realize pretightning force.
For realizing above object, the technical solution adopted in the utility model: a kind of lathe pneumatic jacking device, is characterized in that it comprises thimble (1), thimble shell (2), air inlet pipe (3), gas reversing arrangement (4), reversing switch (5), commutation tracheae I (6), commutation tracheae II (7), cylinder (8), outer snap ring (9), handwheel (10), extrapolability ball bearing (11), movable axis (12), internal force ball bearing (13), interior snap ring (14); Described thimble (1) is arranged in thimble shell (2) by interference fits; Thimble shell (2) is arranged in frame by supporting seat (17), in thimble shell (2) top planes, gas reversing arrangement (4) is installed, and thimble shell (2) one ends are provided with cylinder (8); Cylinder (8) central through hole place is provided with one can realize reciprocating movable axis (12), and described movable axis (12) center is through hole; Screw mandrel (15) is by internal thread hole (16) threaded engagement of movable axis (12) central through hole and thimble (1); Screw mandrel (15) is provided with the interior snap ring of outer snap ring (9) (14), and outer snap ring (9) is provided with extrapolability ball bearing (11) with movable axis (12) end face, and interior snap ring (14) is provided with internal force ball bearing (13) with movable axis (12) end face; Screw mandrel (15) end is provided with handwheel (10).
Under better performance, thimble (1) keeps axiality with thimble shell (2) endoporus.
Under better performance, screw mandrel (15) keeps axiality with the internal thread hole (16) of thimble (1), and screw mandrel (15) keeps axiality with movable axis (12).
The beneficial effects of the utility model are, simple in structure, adopt air cylinder driven thimble top tight workpiece, the reduction that operation labour intensity is larger, and be swift in motion, pressure is stable, safe and reliable.Because screw mandrel end is provided with handwheel, thereby the adjustment that the parts of different size clamp can adapt to the workpiece to be processed of different size.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model is arranged on the structural representation on lathe.
Numerical reference described in figure is expressed as: 1, thimble; 2, thimble shell; 3, air inlet pipe; 4, gas reversing arrangement; 5, reversing switch; 6, commutation tracheae I; 7, commutation tracheae II; 8, cylinder; 9, outer snap ring; 10, handwheel; 11, extrapolability ball bearing; 12, movable axis; 13, internal force ball bearing; 14, interior snap ring; 15, screw mandrel; 16, internal thread hole; 17, supporting seat.
The specific embodiment
As shown in Figure 1, structure annexation of the present utility model: it comprises thimble 1, thimble shell 2, air inlet pipe 3, gas reversing arrangement 4, reversing switch 5, commutation tracheae I 6, commutation tracheae II 7, cylinder 8, outer snap ring 9, handwheel 10, extrapolability ball bearing 11, movable axis 12, internal force ball bearing 13, interior snap ring 14; Described thimble 1 is arranged in thimble shell 2 by interference fits; Thimble shell 2 is arranged in frame 20 by supporting seat 17, in thimble shell 2 top planes, gas reversing arrangement 4 is installed, and thimble shell 2 one ends are provided with cylinder 8; Cylinder 8 central through hole places are provided with one can realize reciprocating movable axis 12, and described movable axis 12 centers are through hole; Screw mandrel 15 is by internal thread hole 16 threaded engagement of movable axis 12 central through holes and thimble 1; Screw mandrel 15 is provided with the interior snap ring 14 of outer snap ring 9, and outer snap ring 9 is provided with extrapolability ball bearing 11 with movable axis 12 end faces, and interior snap ring 14 is provided with internal force ball bearing 13 with movable axis 12 end faces; Screw mandrel 15 ends are provided with handwheel 10.
