Abstract

The invention relates to a rapid auto-clamping clamp. The clamp comprises a fan-shaped clamp body, a fan-shaped clamping groove is formed in the clamp body, a rotation pin is arranged on a top end symmetrical line of the clamp body, the clamp body is connected with a lever through the rotation pin, the upper end side of the lever contacts with a shifting rod, a spring sheet is mounted on the cambered side of the clamp body through bolts, a workpiece is clamped in the clamping groove, and one end surface of the workpiece is tightly pushed by the tool center. By means of the technical scheme, the clamping is simple, clamping is safe, reliable and rapid, the labor intensity of workers is reduced, and the clamp is suitable for batch production.

Description

A kind of fast from the pinching fixture
Technical field
The present invention relates to the fixture field, be specifically related to a kind of fast from the pinching fixture.
Background technology
Heart-shaped fixture is generally used on lathe and grinding machine, the operation in past adopts screw immediate roof clamping of workpieces usually, so not only required great effort but also inconvenience, while especially producing in batches, more aobvious loaded down with trivial details, another kind is newly the device of stirring with lever at lathe, grinding machine, but when just starting shooting bed, between lever and workpiece, very easily produce and clash into, the clamping poor reliability, cause lathe tool cutter head tipping or excircle of workpiece to be worn into concave arc, cause unnecessary economic loss.
Summary of the invention
The object of the invention is to overcome the problem that prior art exists, provide a kind of fast from the pinching fixture.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of fast from the pinching fixture, comprise jig main body, described jig main body is fan-shaped, be provided with fan-shaped clip slot in described jig main body, on the line of symmetry of described jig main body top, be provided with rotational pin, described jig main body connects a lever by described rotational pin, described lever upper side contacts with a driving lever, by screw, a spring leaf is installed on the arcuate flanks of described jig main body, holding workpiece in described clip slot, described workpiece one end face holds out against by lathe is top.
Further, described driving lever is at least described rotational pin to five times of described workpiece distance to the distance of described rotational pin, and described lever lower surface is that inclined plane and inclination angle are 20 °-40 °.
Preferably, described spring leaf contacts and fits with described lever upper side.
The invention has the beneficial effects as follows:
Adopt technical solution of the present invention, clamping is simple, clamps safe and reliablely to reduce labor strength fast, is applicable to producing in enormous quantities.
The accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is left view of the present invention.
Number in the figure explanation: 1, jig main body, 2, fan-shaped clip slot, 3, rotational pin, 4, lever, 5, driving lever, 6, screw, 7, spring leaf, 8, workpiece, 9, lathe is top.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in seeing figures.1.and.2, a kind of fast from the pinching fixture, comprise jig main body 1, described jig main body 1 is fan-shaped, be provided with fan-shaped clip slot 2 in described jig main body 1, be provided with rotational pin 3 on described jig main body 1 top line of symmetry, described jig main body 1 connects a lever 4 by described rotational pin 3, described lever 4 upper side contact with a driving lever 5, by screw 6, a spring leaf 7 is installed on the arcuate flanks of described jig main body 1, the interior holding workpiece 8 of described clip slot 2, described workpiece 8 one end faces hold out against by lathe top 9.
Further, described driving lever 5 is at least to described workpiece 8 distances five times of described rotational pin 3 to the distance of described rotational pin 3, and described lever 4 lower surfaces are that inclined plane and inclination angle are 20 °-40 °.
Preferably, described spring leaf 7 contacts and fits with described lever 4 upper side.
Principle of the present invention:
Closely-spaced between workpiece 8 and rotational pin 3, the vibration while can active surface just starting, spring leaf 7 is due to the existence of elastic force, and the moment that jig main body 1 is started at lathe with workpiece 8 also can keep reliable the connection.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
