Abstract

The utility model discloses a clamp. The clamp comprises a base plate, wherein a first sliding groove is formed in the upper surface of the base plate; at least two sliding baffle plates are arranged in the first sliding groove; each sliding baffle plate comprises a sliding baffle plate body capable of sliding in the first sliding groove and a movable block connected onto the sliding baffle plate body through a spring; each sliding baffle plate body is connected with a fixed device capable of being used for fixing the base plate; opposite surfaces of the two movable blocks are vertical surfaces; a second sliding groove parallel to the first sliding groove is further formed in the base plate; the base plate is further provided with a clamping block capable of sliding along the second sliding groove; a third peripherally closed sliding groove capable of accommodating the movable blocks to slide is formed in the bottom of the clamping block. In the clamp, clamping can be completed without applying a clamping force additionally or adopting other clamping equipment, and the clamp is simple in structure and convenient to operate.

Description

A kind of fixture

Technical field

The utility model relates to a kind of fixture, is a kind of fixture specifically.

Background technology

Fixture, is to be used for fixing processing object, makes it to occupy correct position, with the device of accepting construction or detecting, claims again jig.In the time of processing work, for make the surface of workpiece can reach the size, geometry of drawing regulation and with the technical requirement such as other surperficial relative-position errors, before processing, workpiece must be installed to (location), clip (clamping).Fixture is made up of setting element, clamping device conventionally.

Fixture of the prior art, it, often need to be by other instruments in fixture process, and need to apply with external force, and this mode is complex structure but also troublesome poeration not only.

Utility model content

The technical problems to be solved in the utility model is to provide simple, the easy to operate fixture of a kind of clamping.

For addressing the above problem, the utility model provides a kind of fixture, comprise base plate, it is characterized in that, described plate upper surface is provided with the first chute, in described the first chute, be provided with at least two sliding blocks, described sliding block comprises the sliding block body that can slide in described the first chute and is connected to the movable block on described sliding block body by spring, on described sliding block body, be connected with and can be used for the fixture fixing with described base plate, the face that two movable blocks are relative is vertical plane, on described base plate, be also provided with second chute parallel with described the first chute, and the clamp that can slide along described the second chute, described clamp bottom is provided with and can holds the 3rd chute that described movable block slides and surrounding is sealed.

As further improvement of the utility model, the bottom land of described the first chute is provided with along described the first chute distribution of lengths, vertically run through the through hole of described base plate, described sliding block body below is connected with and is provided with externally threaded connecting rod, described connecting rod is connected with a nut through described through hole, and described through hole is to hold the counterbore that described nut sinks to.

As further improvement of the utility model, the side of described the first chute is also equipped with the 4th chute, and described sliding block body two sides are provided with the projection that can slide in described the 4th chute respectively.

As further improvement of the utility model, described movable block also comprises that two is parallel and with the side vertical with described base plate and be connected the inclined-plane of the inclination of two sides.

As further improvement of the utility model, the upper surface of described base plate is also provided with scale.

The beneficial effects of the utility model are, first regulate two positions between sliding baffle plate, the length that makes distance between two sliding baffle plates equal workpiece adds a fixed value, this fixed value is the twice of the distance of the near side (ns) of base to the three chutes of clamp vertical plane, then along the second chute slip clamp, two clamps are clamped workpiece, now, the vertical plane of sliding baffle plate retreats prevention clamp, thereby can only clamp forward this workpiece, adopt in this way, without applying in addition clamping force also without adopting other apparatus for fastening, simple in structure, easy to operate.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the cutaway view of Fig. 1 side-looking;

Fig. 3 is the structural representation of sliding baffle plate in Fig. 1;

Wherein: 2-base plate; The sliding block of 4-; 6-the first chute; The sliding block body of 10-; 12-movable block; 14-the second chute; 16-clamp; 18-projection; 20-the 4th chute; 22-connecting rod; 24-nut; 26-through hole.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further details.

As Figure 1-3, the utility model comprises base plate 2, base plate 2 upper surfaces are provided with the first chute 6, in the first chute 6, be provided with at least two sliding blocks 4, sliding block 4 comprises and can and be connected to the movable block 12 on sliding block body 10 by spring at the sliding block body 10 of the first chute 6 interior slips, on sliding block body 10, be connected with and can be used for the fixture fixing with base plate 2, the relative face of two movable blocks 12 is vertical plane, on base plate 2, be also provided with second chute 14 parallel with the first chute 6, and the clamp 16 that can slide along the second chute 14, clamp 16 bottoms are provided with and can hold the 3rd chute that movable block 12 slides and surrounding is sealed.

In the utility model, first regulate two positions between sliding baffle plate, the length that makes distance between two sliding baffle plates equal workpiece adds a fixed value, this fixed value is the twice of the distance of the near side (ns) of base to the three chutes of clamp 16 vertical planes, then along the second chute 14 slip clamps 16, two clamps 16 are clamped workpiece, now, the vertical plane of sliding baffle plate retreats prevention clamp 16, thereby can only clamp forward this workpiece, adopt in this way, without applying in addition clamping force also without adopting other apparatus for fastening, simple in structure, easy to operate.

As further improvement of the utility model, the bottom land of the first chute 6 is provided with along the first chute 6 distribution of lengths, vertically run through the through hole 26 of base plate 2, sliding block body 10 belows are connected with and are provided with externally threaded connecting rod 22, connecting rod 22 is connected with a nut 24 through through hole 26, and through hole 26 is for can hold the counterbore that nut 24 sinks to.
