Abstract

The invention belongs to the clamping apparatus design technology and provides a rapid clamp. The rapid clamp comprises a clamp body, a movable block, a pressing screw and a fastening nut, wherein the clamp body consists of a bottom plate and a vertical plate; the bottom plate is a hexagonal plate-shaped structure, a plurality of triangular inclined teeth which are connected in parallel are formed in the right end of the top surface of the bottom plate; the inclined direction of the inclined teeth in the bottom plate faces towards the left end direction, without inclined teeth, of the bottom plate; a hexagonal vertical plate is arranged at the left end of the top surface of the bottom plate; the width of the vertical plate is the same as that of the bottom plate; the movable block is a hexagonal, a plurality of triangular inclined teeth which are connected in parallel are bumped in the bottom of the movable block; the inclined direction of the inclined teeth of the movable block is reverse to that of the inclined teeth on the bottom plate, the tooth shape sizes are the same and matched with one another; a threaded hole is formed in a direction vertical to the tooth shapes of the movable block of the side surface of the movable block; the pressing screw penetrates through the threaded hole in the movable block, and the fastening nut sleeves the pressing screw for fastening the pressing screw on the movable block.

Description

A kind of quick-speed jigs

Technical field

The invention belongs to clamping apparatus designing technique, relate to a kind of quick-speed jigs.

Background technology

In field of machining, often need clamping workpiece, traditional workpiece adopts vice clamping, the screw thread travel of vice is longer, clamping, dismounting workpiece all need rotational workpieces for a long time, sometimes often need the jaw of adjustment vice for a long time when the different part of working width, operator takes the much technological preparation time on this, is unfavorable for increasing work efficiency.Needs address this problem.

Summary of the invention

Object of the present invention: propose a kind of quick-speed jigs, to facilitate workpiece, improves clamping, dismounting work speed.

Technical scheme of the present invention: a kind of quick-speed jigs, it is made up of clamp body, loose piece, housing screw and clamp nut; Clamp body is made up of a base plate and a riser; Base plate is the platy structure of a hexahedron, some triangle helical teeth be connected side by side are had at the end face right-hand member of base plate, on base plate, the incline direction of helical teeth does not have the left end direction of helical teeth towards base plate, and have the riser of hexahedron shape at the end face left end of base plate, the width of riser is identical with base plate; The profile of loose piece is hexahedron shape, at the some triangle helical teeth be connected side by side of the bottom protrusion of loose piece, on loose piece, the incline direction of the incline direction of helical teeth and helical teeth on base plate is contrary, profile of tooth size is identical and cooperatively interact, a screwed hole is had in the direction that the side of loose piece is vertical with profile of tooth on loose piece, housing screw is through loose piece upper screwed hole, and clamp nut is enclosed within housing screw and is fastened on loose piece by housing screw.

Advantage of the present invention: loose piece of the present invention can according to the movement fast of the size of clamping workpiece, decrease the time of tightening housing screw, dismantle workpiece also very convenient simultaneously, as long as some housing screws of pine just can take loose piece away slightly, decrease loose nut and the time of getting workpiece, the present invention is easy to be handy, improves the efficiency of clamping workpiece, dismounting.

Accompanying drawing illustrates:

Detailed description of the invention:

Below the present invention is described in further details.See Fig. 1, Fig. 2, Fig. 3 a, Fig. 3 b, a kind of quick-speed jigs.It is characterized in that, it is made up of clamp body 1, loose piece 2, housing screw 3 and clamp nut 4; Clamp body 1 is made up of an a base plate 1a and riser 1b; Base plate 1a is the platy structure of a hexahedron, some triangle helical teeth 1d be connected side by side are had at the end face 1c right-hand member of base plate 1a, on base plate 1a, the incline direction of helical teeth 1d does not have the left end direction of helical teeth 1d towards base plate 1a, identical with base plate 1a at the width of the riser 1b that the end face left end of base plate 1a has hexahedron shape to raise up, riser 1b; The profile of loose piece 2 is hexahedron shape, at the some triangle helical teeth 2a be connected side by side of the bottom protrusion of loose piece 2, on loose piece 2, the incline direction of the incline direction of helical teeth 2a and helical teeth 1d on base plate 1a is contrary, profile of tooth size is identical and cooperatively interact, a screwed hole 2b is had in the direction that the side 2c of loose piece 2 is vertical with profile of tooth 2a on loose piece 2, housing screw 3 is through loose piece 2 upper screwed hole 2b, and clamp nut 4 is enclosed within housing screw 3 and is fastened on loose piece 2 by housing screw 3.

The present invention will treat on the riser 1b side 1e that clamping workpiece 5 pastes with clamp body 1 in use, then the loose piece 2 installing housing screw 3 and clamp nut 4 is placed on the nearer helical teeth 1d of distance workpiece, make housing screw 3 and treat the nearest of clamping workpiece 5, then housing screw 3 is screwed, clamping band clamping workpiece 5 also screws clamp nut 4, completes the clamping work of workpiece 5.During dismounting workpiece 5, unclamp clamp nut 4 and housing screw 3 successively, more upwards take away loose piece 2 and just can dismantle workpiece 5.

The present invention is easy to be handy, its loose piece can according to the movement fast of the size of clamping workpiece, decrease the time of tightening housing screw, dismantle workpiece also very convenient simultaneously, as long as some housing screws of pine just can take loose piece away slightly, decrease loose nut and the time of getting workpiece, improve the efficiency of clamping workpiece, dismounting, be adapted at the multiple lathes such as milling machine, planer, grinding machine, numerical control machining center, drilling machine use.
