Abstract
The invention relates to the technical field of mechanical clamping, in particular to a three-jaw clamp. A base which is disc shaped is evenly provided with three grooves; the inner face of each groove is provided with a first threaded hole in which a clamping device is mounted. Each clamping device comprises screw; a moving seat which is movable and a jaw connected to the moving seat are disposed on each screw. One end of each screw extends out of the base and connected with a motor. One end, facing the center of the base, of each jaw is provided with a V-shaped groove; two sides of each V-shaped groove are provided with slide rails facing each other. Two sides of each moving seat are provided with two slide grooves facing each other. The slide rails are used with the slide grooves. Two sides of each V-shaped groove are provided with wearing sheets. The three-jaw disc is simple in structure, has the function of automatic clamping and is wear resistant.
Description
Technical field
The present invention relates to mechanical fixture technology field, particularly relate to a kind of scroll 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) complex structure, needs clamping manually, waste time and energy; 2) claw medial surface is often and absorption surface, long-time use after, easily cause claw medial surface to produce wearing and tearing.
Summary of the invention
The object of this invention is to provide structure simple, can automatically clamp, and anti abrasive a kind of scroll chuck.
Technical scheme of the present invention is as follows:
A kind of scroll 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 motor; Described claw is provided with " V " shape fluting towards the one end at base center; Described fluting both sides are relatively set with two slide rails; Described Mobile base both sides are provided with two chutes relatively; Described slide rail and chute with the use of; Described " V " shape fluting both sides are equipped with wear plate.
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: drive the rotation of screw rod by the startup of motor and then drive the movement of Mobile base, 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, disable motor, makes three claws be clamped by cylindrical work; Because claw is provided with " V " shape fluting towards the one end at base center, adopt " V " shape fluting effectively can clamp cylindrical work; By slide rail and chute with the use of, avoid the rotation of Mobile base in moving process; During due to " V " shape fluting clamping cylindrical workpiece, long-time use after, easily wearing and tearing, by arranging wear plate, extending claw service life.
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 4 is screw rod, and 5 is Mobile base, and 6 is claw, and 7 is motor, and 8 is " V " shape fluting, and 9 is slide rail, and 10 is chute, and 11 is wear plate, and 12 is backstay, and 13 is threaded portion.
Detailed description of the invention
Embodiment 1
Shown in Fig. 1-Fig. 3, a kind of scroll 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 4, and screw rod is provided with moveable Mobile base 5, and the claw 6 that Mobile base connects; Described screw rod one end extends outside the base and is connected with motor 7; Described claw is provided with " V " shape fluting 8 towards the one end at base center; Described fluting both sides are relatively set with two slide rails 9; Described Mobile base both sides are provided with two chutes 10 relatively; Described slide rail and chute with the use of; Described " V " shape fluting both sides are equipped with wear plate 11.
Drive the rotation of screw rod by the startup of motor and then drive the movement of Mobile base, 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, disable motor, makes three claws be clamped by cylindrical work; Because claw is provided with " V " shape fluting towards the one end at base center, adopt " V " shape fluting effectively can clamp cylindrical work; By slide rail and chute with the use of, avoid the rotation of Mobile base in moving process; During due to " V " shape fluting clamping cylindrical workpiece, long-time use after, easily wearing and tearing, by arranging wear plate, extending claw service life.
Embodiment 2
Described base center is provided with the second screw, is provided with backstay 12 in this second screw; Be provided with bottom described backstay with the second screw with the use of threaded portion 13.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 3
On the basis of embodiment 1, 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.
