Abstract
A large-stroke spiral rapid clamping device is characterized in that a clamping mechanism is composed of a clamping screw and a guide sleeve, a spiral groove and an axial groove are formed in the clamping screw, the spiral groove and the axial groove are both trapezoidal grooves or U-shaped grooves, the depths of the grooves are equal, the grooves are connected in a smooth mode, a radial ball pin is arranged on the guide sleeve, the head of the ball pin extends into the spiral groove or the axial groove, and a pressing block and a locking nut are arranged at the head of the clamping rod. The utility model is used for the machining trade, simple structure, convenient operation can realize pressing from both sides tight or loosen the big stroke quick clamp of work piece, obviously improves production efficiency, and the range of application is wide.
Description
Technical field
The utility model relates to a kind of spiral clamping device, particularly big stroke spiral fast fixture.
Background technology
In machining, usually run into some special workpiece, since the restriction of loading and unloading, the necessary grip device that adopts big stroke.Spiral clamping device commonly used even adopt multiple-threaded screw rod, clamps and also needs to rotate a lot of circles when unclamping workpiece, not only bothers but also require great effort, and production efficiency is lower.
The utility model content
The purpose of this utility model be to provide a kind of simple in structure, make easy, easy to operate, the big stroke spiral fast fixture that can enhance productivity.
The technical solution of the utility model is: big stroke spiral fast fixture comprises support, clamp mechanism, its improvements are that clamp mechanism is made of clamping screw and guide pin bushing, described clamping screw is provided with helicla flute and axial groove, both junction rounding ofves, axial groove promptly compresses between the end at helicla flute and clamping screw head, described guide pin bushing is provided with radially ball stud, and the head of ball stud stretches in helicla flute or the axial groove.
Further scheme is that described helicla flute and axial groove are dovetail groove or U-lag, and deep equality; Described spiral fluted pitch angle alpha will=6 °～9 °; Described clamping screw head is provided with briquetting and the locking nut that is threaded with it.
When the utility model uses, rotate clamping screw earlier, when axial groove is aimed at ball stud, screw rod can freely advance long apart from fast moving near workpiece; When helicla flute was aimed at ball stud, the rotary screw pommel played the effect that screw thread clamps, thereby realized the big stroke of workpiece is clamped fast.Otherwise, unclamp and when unloading workpiece, also can realize big fast stroke action.Described helicla flute and axial groove are dovetail groove or U-lag, and both deep equalities, help making and improving transmission efficiency, also make ball stud in the motion of two groove junctions nimbly and freely.Spiral fluted pitch angle alpha will=6 °～9 °, for the steel part structure, self-locking is reliable in the time of guaranteeing that screw rod clamps.Screw head is provided with briquetting, and adjustable distance further adapts to the clamping needs of workpiece.The utility model is simple in structure, makes easily, and is easy to operate, can obviously enhance productivity, and especially is fit to big stroke and clamps occasion.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
See figure, clamp mechanism in the big stroke spiral fast fixture is made of clamping screw 1 and guide pin bushing 2, and guide pin bushing is fixed on the support 8, and the clamping screw stage casing is provided with helicla flute 3 and axial groove 4, all become U-lag, and degree of depth unanimity, the slick and sly connection, wherein the spiral fluted pitch angle alpha will is got 7 ° 30 ', guide pin bushing one side is provided with radially ball stud 5, the head of ball stud stretches in helicla flute or the axial groove, is slidingly matched, and clamping screw head (compressing end) is provided with briquetting 7 and the locking nut 6 that is threaded with it.
Claims (4)
