The utility model proposes a kind of novel hydraulic three-jaw self-centering chuck, overcome the low defect of manual operation chuck processing work production efficiency in prior art.
The technical solution of the utility model is achieved in that
A kind of novel hydraulic three-jaw self-centering chuck, comprise chuck body, be located at plane on described chuck body claw, be located at plane San road chute on chuck body, described claw is arranged on described chute; Described claw bottom is provided with sawtooth piece, and described chute top is provided with dentation locating piece, and described dentation locating piece is located described claw by engagement sawtooth piece.
Further, described chuck is connected with hydraulic means, and described hydraulic means is provided with slide block; Described claw is connected with slide, and described slide is arranged in described chute, and described slide end connects described slide block; Described slide end is provided with directional inclination slideway; Described slide block is provided with the sleeve body being embedded in described directional inclination slideway, and described sleeve body moves up and down and drives described slide to do radial motion along described chute along described directional inclination slideway.
Further, described hydraulic means comprises oil cylinder, connects oil return pipe and the oil inlet pipe of described oil cylinder; Described oil return pipe and oil inlet pipe all connect Hydraulic Station, between described oil cylinder and described oil return pipe, are provided with magnetic valve, between described oil cylinder and described oil inlet pipe, are provided with check valve.
Further, described oil cylinder comprises piston rod, and described slide block is arranged on described piston rod.
Further, for making operation more accurate, described chute is distributed in plane on described chuck body.
Use technical solutions of the utility model, fix by locating piece because of claw, prevented claw slip, workpiece is more firmly clamped, improved the accurate rate of processing.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model chuck structure top view.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
See Fig. 1 and Fig. 2, in the utility model embodiment, a kind of hydraulic self-centering chuck, comprises chuck body 1, is located at the claw 2 of plane on chuck body 1, is located at plane San road chute 3 on chuck body 1; Wherein, claw is located on chute 3, and can slide and clamping work pieces along chute; In the utility model embodiment, claw 2 bottoms are provided with sawtooth locating piece 21, are provided with the dentation locating piece 31 of engagement sawtooth locating piece 21 on chute 3 tops.Thus, in the time of claw clamping work pieces, the dentation locating piece 31 on chute top, by the sawtooth locating piece 21 of engagement claw 2 bottoms, with stationary jaw, strengthens the dynamics of claw clamping work pieces, has more ensured the degree of accuracy of workpiece processing.
In the utility model embodiment, for further liberation is artificial, enhance productivity, chuck is preferably connected with hydraulic means, is provided with slide block 5 on hydraulic means; Wherein, each claw 1 is all connected with slide 4, and slide 4 is arranged in chute 3 and slides along chute 3, end 40 connection sliding blocks 5 of slide 4; End 40 at slide 4 is provided with directional inclination slideway 41; Slide block 5 is provided with the sleeve body being embedded in directional inclination slideway 41, and sleeve body moves up and down and drives slide 4 and claw 2 to do radial motion along chute 3 simultaneously along directional inclination slideway 41.In the utility model embodiment, sleeve body is not shown.
In the utility model embodiment, hydraulic means comprises oil cylinder 10, connects oil return pipe 11 and the oil inlet pipe 12 of oil cylinder 10; Oil return pipe 11 and oil inlet pipe 12 all connect Hydraulic Station 13, between oil cylinder 10 and oil return pipe 11, are provided with magnetic valve 14, between oil cylinder 10 and oil inlet pipe 12, are provided with check valve 15.
Wherein, slide block 5 is arranged on the piston rod 101 of oil cylinder 10.
Further, for making operation more accurate, chute 3 is distributed in the upper plane of chuck body 1.
While using the hydraulic means of technical solutions of the utility model, Hydraulic Station 13 is worked, hydraulic oil enters in the cavity of oil cylinder 10 by oil inlet pipe 12 and check valve 15, by upwards jack-up of piston rod 101, be with slide block 5 up by piston rod 101, sleeve body is by up the directional inclination slideway 41 along on slide 4 simultaneously; Because the directional inclination slideway 41 on slide 4 ends 40 is directional inclination shape, therefore, on sleeve body, be about to drive slide 4 to do centripetal moving along the tri-road chutes 3 of plane Shang on chuck body 1, the centripetal motion of slide 4 drives claw 2 to do centripetal motion clamping work pieces simultaneously, sawtooth locating piece 21 stationary jaws 2 simultaneously, prevent that claw from sliding, to improve the accurate rate of workpiece processing.
Magnetic valve 14 is worked, and hydraulic oil is drawn back to Hydraulic Station 13 by oil return pipe 11, makes piston rod 101 be with slide block 5 descending, and simultaneously sleeve body is by the directional inclination slideway along on slide 4 41 times; Because the directional inclination slideway 41 on slide is directional inclination shape, sleeve body is about to drive for 51 times slide 4 to do centrifugal motion along the tri-road chutes 3 of plane Shang on chuck body, and the centrifugal motion of slide 4 drives claw to do centrifugal motion simultaneously and loosens workpiece.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
