Abstract
The utility model discloses a clamp. The clamp comprises a U-shaped clamp seat, an adjustment screw rod and clamp bodies, wherein the adjustment screw rod is arranged on the clamp seat, and adjustment handles are arranged at the two ends of the adjustment screw rod. Each clamp body comprises a transverse claw and a vertical wall, wherein clamping teeth are arranged on the transverse claw, and an abrasion-resistant layer is arranged outside the clamping teeth. The vertical walls are installed on a sliding block, the adjustment screw rod is provided with a sliding rail meshed with the sliding block, and the number of the clamp bodies is two. The clamp is good in positioning stability, good in clamping performance, long in service time, capable of clamping objects with irregular surfaces and easy to operate, the tightness degree of workpiece clamping can be judged without manual action on a workpiece, time and labor are saved, and work efficiency is improved.
Description
Technical field
The utility model relates to field of machining, relates 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 when processing work, for the dimensions that makes the surface of workpiece can reach drawing to specify, geometry and with the technical requirement such as other surperficial relative-position errors, before processing, workpiece must be installed to location, clamp.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, when existing fixture work, clamping frequently and loosening in process, normally judge the degree of tightness situation of piece-holder by manually acting on workpiece, expend time in more, increased labour intensity, reduced operating efficiency.
Utility model content
The purpose of this utility model has been 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, improve operating efficiency.
The technical solution adopted in the utility model 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 of graphite atom composition 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, guarantee 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.
When use, rotate adjusting screw(rod) by regulating handle, slide block is under the effect of adjusting screw(rod), promote clamp body and complete clamping work to centre movement on slide rail, now can judge jam by the scale on slide rail, ensure 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, the beneficial effects of the utility model are as follows:
The utility model is by two clamp bodies of design, clamp body is arranged on slide rail by slide block, complete clamping work by adjusting screw(rod) control clamp body, 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 there will be abrasion condition after fixture 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, guarantee clamp body in OK range, prevents injuring part to the pressure of part.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model 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, ensure clamp body to the pressure of workpiece in OK range, prevent from damaging workpiece, described clamp body 3 has two.When use, rotate adjusting screw(rod) 2 by regulating handle 4, slide block 9 is under the effect of adjusting screw(rod) 2, promote clamp body 3 and complete clamping work to centre movement on slide rail 10, now can judge jam by the scale 11 on slide rail 10, ensure the chucking power of workpiece to be unlikely to excessive, prevent 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.
