Abstract
The utility model provides a hydraulic self-centering chuck which comprises a chuck body, three clamping jaws arranged on the upper plane of the chuck body, and three sliding grooves arranged on the upper plane of the chuck body, wherein each clamping jaw is connected with a sliding seat; the sliding seats are respectively arranged in the sliding grooves and can slide along the sliding grooves; the tail end of each sliding seat is provided with a directional inclined slide way; the chuck is connected with a hydraulic device; the hydraulic device is provided with a sliding block; the sliding block is provided with sliding sleeve bodies embedded in the directional inclined slide ways; the sliding sleeve bodies move up and down along the directional inclined slide ways, and the sliding seats are driven to make radial motion along the sliding grooves by the sliding sleeve bodies. After the technical scheme is adopted, the centripetal or centrifugal radial motion of the sliding seats is driven by the up and down movement of the sliding sleeve bodies, so that the size of a hydraulic chuck system is reduced, and the production efficiency is effectively increased.
Description
Technical field
The utility model relates to machine tool accessories technical field, relates in particular to a kind of hydraulic self-centering chuck.
Background technology
The work of the scroll chuck of using on traditional lathe generally relies on workman to clamp by hand, most pressing plate, adjustment bolt and cash pledge bolts etc. of adopting carry out the sequence of operations such as artificial fine setting, not only increase workman's labour intensity, and required clamping force is very large, also usually there is not clamping situation, be difficult to guarantee the even of clamping force, productivity ratio is lower.The patent No. is CN201220743072, and name is called a kind of patent of hydraulic pressure scroll chuck, discloses a kind of technology that drives claw radial motion by hydraulic jack, although alleviated to a certain extent manpower, complicated structure, the corresponding increase of cost; And whole clamping system self length is longer, and the automatic fixture of the brill milling equipment Structure of need compactness of machining center, therefore, the chuck system being formed with this patented technology scheme cannot be equipped on the brill milling equipment of numerical control machining center.
Utility model content
The utility model proposes a kind of hydraulic self-centering chuck, overcome the low defect of manual operation chuck processing work production efficiency in prior art, and solved the baroque problem of general oild chuck clamping system.
The technical solution of the utility model is achieved in that
A kind of hydraulic self-centering chuck, comprise chuck body, be located at plane on described chuck body three claws, be located at plane San road chute on chuck body; Described each claw is all connected with slide, and described slide is arranged in described chute and along described chute and slides, and the end of described slide is provided with directional inclination slideway; Described chuck is connected with hydraulic means, on described hydraulic means, be provided with slide block, 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.
Further, 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.
Use technical solutions of the utility model, on the slide that connects claw, be provided with directional inclination slideway, on hydraulic means, be provided with along the directional inclination slideway sleeve body that moves, when sleeve body is moved in directional inclination slideway, drive slide is done to centripetal or centrifugal motion along chute, meanwhile, slide does centripetal or centrifugal motion by drive claw along chute.Move because moving up and down of sleeve body driven the centripetal or centrifugal radial of slide, reduced the volume of oild chuck system, and effectively improved production efficiency.
Accompanying drawing explanation
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 skills, 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.
The specific embodiment
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, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills 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, in the utility model embodiment, a kind of hydraulic self-centering chuck, comprise chuck body 1, be located at plane on chuck body 1 three claws 2, be located at plane San road chute 3 on chuck body 1; Each claw 1 is all connected with slide 4, and slide 4 is arranged in chute 3, and the end 40 of slide 4 is provided with directional inclination slideway 41; Chuck is connected with hydraulic means, is provided with slide block 5 on hydraulic means, and 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.
For making operation more accurate, in the utility model, chute 3 is preferably distributed in the upper plane of chuck body 1.
Movable for claw 2 claw after clamping work pieces is difficult for, in the utility model embodiment, claw 2 bottoms are provided with sawtooth piece 21, and chute 3 tops are provided with dentation locating piece 31, and dentation locating piece 31 is located described claw 2 by engagement sawtooth piece 21.
