Abstract
The invention relates to the technical field of mechanical clamping, and in particular relates to a novel three-jaw chuck. The novel three-jaw chuck comprises a disciform base which is uniformly provided with three grooves, the inner side of each groove is provided with a first screw hole, and a clamping device is arranged in each first screw hole; each clamping device comprises a screw on which a movable moving seat and a claw connected to the moving seat are arranged; one end of the screw extends out of the base and is connected to a hand grip; one end of the claw facing towards the center of the base is provided with a V-shaped groove. The novel three-jaw chuck is simple in structure and capable of achieving fine adjustment.
Description
Technical field
The present invention relates to mechanical fixture technology field, particularly relate to Novel three-jaw chuck.
Background technology
Scroll chuck utilizes to be distributed on moving radially of three movable jaws on chuck body, the machine tool accessories of Workpiece clamping and location; There is following point in current scroll chuck: 1) scroll chuck internal structure is comparatively complicated, when needing maintenance, and the time-consuming effort of installing/dismounting; 2), during clamping, can not realize fine setting, clamping effect is not good.
Summary of the invention
The object of this invention is to provide structure simple, and the Novel three-jaw chuck of fine setting can be realized.
Technical scheme of the present invention is as follows:
Novel three-jaw chuck, comprises discoid base; Described base is evenly equipped with three flutings, fluting medial surface is equipped with the first screw, is all provided with clamping device in this first screw; Described clamping device comprises screw rod, and screw rod is provided with moveable Mobile base, and the claw that Mobile base connects; Described screw rod one end extends outside the base and is connected with handle; Described claw is provided with " V " shape fluting towards the one end at base center.
Described clamping device also comprise fluting both sides base top surface on be relatively set with two slide rails; Described claw bottom surface is provided with two chutes relatively; Described slide rail and chute with the use of.
Described base center is provided with the second screw, is provided with backstay in this second screw; Be provided with bottom described backstay with the second screw with the use of threaded portion.
Described slide rail is in " convex " font; Described chute is in " convex " font.
The invention has the beneficial effects as follows: by the movement rotarily driving Mobile base of screw rod, the mobile claw be connected with Mobile base that drives of Mobile base moves forward and backward; When claw move to prop up cylindrical workpiece time, stop the rotation screw rod, and cylindrical work is clamped by three claws; Fine setting is realized by the screw thread on screw rod; Because claw is provided with " V " shape fluting towards the one end at base center, adopt " V " shape fluting effectively can clamp cylindrical work.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
Fig. 2 is clamping device structural representation of the present invention;
Fig. 3 is positional lever structure schematic diagram of the present invention;
In accompanying drawing, 1 is base, and 2 is fluting, and 3 is screw rod, and 4 is Mobile base, and 5 is claw, and 6 is handle, and 7 is " V " shape fluting, and 8 is slide rail, and 9 is chute, and 10 is backstay, and 11 is threaded portion.
Detailed description of the invention
Embodiment 1
Shown in Fig. 1-Fig. 3, Novel three-jaw chuck, comprises discoid base 1; Described base is evenly equipped with three flutings 2, fluting medial surface is equipped with the first screw, is all provided with clamping device in this first screw; Described clamping device comprises screw rod 3, and screw rod is provided with moveable Mobile base 4, and the claw 5 that Mobile base connects; Described screw rod one end extends outside the base and is connected with handle 6; Described claw is provided with " V " shape fluting 7 towards the one end at base center.
By the movement rotarily driving Mobile base of screw rod, the mobile claw be connected with Mobile base that drives of Mobile base moves forward and backward; When claw move to prop up cylindrical workpiece time, stop the rotation screw rod, and cylindrical work is clamped by three claws; Because claw is provided with " V " shape fluting towards the one end at base center, adopt " V " shape fluting effectively can clamp cylindrical work.
Embodiment 2
Described clamping device also comprise fluting both sides base top surface on be relatively set with two slide rails 8; Described claw bottom surface is provided with two chutes 9 relatively; Described slide rail and chute with the use of.By slide rail and chute with the use of, avoid the rotation of Mobile base in moving process.
Embodiment 3
Described base center is provided with the second screw, is provided with backstay 10 in this second screw; Be provided with bottom described backstay with the second screw with the use of threaded portion 11.By arranging threaded portion bottom backstay, making that backstay is dismountable to be connected in the second screw, when the cylindrical workpiece needing clamping with centre bore, the backstay suitable with centre bore aperture can be installed; When not needing to clamp the cylindrical workpiece with centre bore, backstay can be dismantled.
Embodiment 4
On the basis of embodiment 2, described slide rail is in " convex " font; Described chute is in " convex " font.Adopt the slide rail of " convex " font and the chute of " convex " font with the use of, make guide effect better.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
