Abstract

The invention discloses a clamp. The clamp comprises a U-shaped clamp base, an adjusting screw rod and two clamp bodies. The adjusting screw rod is arranged on the clamp base. The two ends of the adjusting screw rod are provided with adjusting handles. Each clamp body comprises a transverse claw and a vertical wall, wherein the transverse claw is provided with a clamp tooth, an abrasion-resisting layer is arranged on the outer face of the clamp tooth, the vertical wall is installed on a sliding block, and the adjusting screw rod is provided with a sliding rail meshed with the sliding block. The clamp is good in positioning stability and clamping performance, long in service life and capable of clamping an object with the irregular surface, operation is easy, the degree of tightness of a clamped workpiece can be judged without manual action on the workpiece, time and labor are saved, and working efficiency is improved.

Description

A kind of fixture
Technical field
The present invention relates to field of machining, relate in particular to a kind of fixture.
Background technology
Fixture is to be used for fixing processing object in machine-building process, makes it to occupy correct position, with the device of accepting construction or detecting.Wherein jig is the most common, on lathe, during processing work, for making the surface of workpiece can reach size, geometry and the specification requirements such as relative-position error surperficial with other of drawing regulation, workpiece must be installed to location, clamping before processing.But the fixture of prior art exists, and position stability is poor, processing parts is prone to vibrations displacement, the loosening problem of fixture, and then affect the machining accuracy of part, and during for the object of surface imperfection, fastening poor effect, most clamp bodies are steel structure, after using a period of time, there will be wearing and tearing, the effect of impact clamping.In addition, during existing fixture work, clamping frequently and loosening in process, normally by manually acting on workpiece, judging the degree of tightness situation of piece-holder, expending time in more, increasing labour intensity, reducing operating efficiency.
Summary of the invention
The object of this invention is to provide the fixture that a kind of position stability is good, clamping performance is good, service time is long, and can clamp for the object of surface imperfection, simple to operate, do not need to judge by manually acting on workpiece the degree of tightness situation of piece-holder, time saving and energy saving, improved operating efficiency.
The technical solution used in the present invention is as follows:
A kind of fixture, comprise U-shaped clamping fixture seat, adjusting screw(rod) and clamp body, described adjusting screw(rod) is arranged on clamping fixture seat, adjusting screw(rod) two ends are provided with regulating handle, and described clamp body comprises horizontal pawl and perpendicular wall, and described horizontal pawl is provided with latch, the outside of latch is provided with wearing layer, described perpendicular wall is arranged on slide block, and described adjusting screw(rod) is provided with the slide rail being meshed with slide block, and described clamp body has two.
Described wearing layer is DLC coating.DLC be a kind of by carbon form, similar with diamond in nature, there is again the material that graphite atom forms structure simultaneously, there is high rigidity and high elastic modulus, low friction coefficient, wear-resistant and good vacuum tribological property.
Described DLC coating layer thickness is 1-2mm.
On described slide rail, be provided with scale.Can be the in the situation that of clamp body fast moving, assurance clamp body in OK range, prevents from damaging workpiece to the pressure of workpiece.
Described adjusting screw(rod) is threaded connection and is arranged on clamping fixture seat.
During use, by regulating handle, rotate adjusting screw(rod), slide block is under the effect of adjusting screw(rod), promote clamp body and to centre movement, complete clamping work on slide rail, now can judge jam by the scale on slide rail, guarantee the chucking power of workpiece to be unlikely to excessive, prevent defective work piece.Otherwise counter-rotating adjusting screw(rod), can make clamp body move away from center position to two ends, thereby loosen workpiece simultaneously.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention is by two clamp bodies of design, clamp body is arranged on slide rail by slide block, by adjusting screw(rod), control clamp body and complete clamping work, not only avoid processing parts to be prone to vibrations displacement, the loosening problem of fixture, play the effect of location simultaneously, position stability is good, time saving and energy saving, has improved working (machining) efficiency.Clamp body arranges horizontal pawl and perpendicular wall, and horizontal pawl is provided with latch, fastening effective, can be for the irregular object of clamping surface, the outside of latch is provided with wearing layer, avoids fixture to there will be abrasion condition after use a period of time, the effect of impact clamping, increases the service life.In addition, scale is set on slide rail, can be the in the situation that of clamp body fast moving, assurance clamp body in OK range, prevents injuring part to the pressure of part.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
Referring to accompanying drawing, a kind of fixture, comprise U-shaped clamping fixture seat 1, adjusting screw(rod) 2 and clamp body 3, described adjusting screw(rod) 3 is threaded connection and is arranged on clamping fixture seat 1, adjusting screw(rod) 2 two ends are provided with regulating handle 4, described clamp body 3 comprises horizontal pawl 5 and perpendicular wall 6, described horizontal pawl 5 is provided with latch 7, the outside of latch 7 is provided with wearing layer 8, wearing layer 8 is the DLC coating of 1.5mm thickness, described perpendicular wall 6 is arranged on slide block 9, described adjusting screw(rod) 2 is provided with the slide rail 10 being meshed with slide block 9, on described slide rail 10, be provided with scale 11, can be the in the situation that of clamp body 3 fast moving, guarantee clamp body to the pressure of workpiece in OK range, prevent from damaging workpiece, described clamp body 3 has two.During use, by regulating handle 4 rotation adjusting screw(rod)s 2, slide block 9 is under the effect of adjusting screw(rod) 2, promote clamp body 3 and to centre movement, complete clamping work on slide rail 10, now can judge jam by the scale 11 on slide rail 10, assurance is unlikely to excessive to the chucking power of workpiece, prevents defective work piece.Otherwise counter-rotating adjusting screw(rod) 2, can make clamp body 3 move away from center position to two ends, thereby loosen workpiece simultaneously.
