Eccentric self-locking type clamping fixture

Abstract

The invention discloses an eccentric self-locking type clamping fixture which comprises a base, a first L-shaped clamping arm, a second L-shaped clamping arm and an eccentric wheel. A first installing seat and a third installing seat which are located on the upper side of the base are rotatably connected with the lower end of the first L-shaped clamping arm and the lower end of the second L-shaped clamping arm correspondingly. The inner side of the middle portion of the first L-shaped clamping arm is rotatably connected with one end of a pull rod through a second installing seat. The other end of the pull rod penetrates through an unthreaded hole in the middle of the second L-shaped clamping arm and then is rotatably provided with the eccentric wheel. A driving handle used for driving the eccentric wheel to rotate is fixedly installed on the outer side of the eccentric wheel. A first pressure foot and a second pressure foot which are used for increasing the stressed area of a workpiece are fixedly arranged at the open end of the first L-shaped clamping arm and the open end of the second L-shaped clamping arm correspondingly. The eccentric self-locking type clamping fixture has the following characteristics of being convenient to operate, high in clamping speed, high in efficiency, reasonable in design, large in compression force, reliable in self-locking, high in universality, wide in application range, simple and compact in structure and convenient to mount and dismount.

Description

technical field [0001] The invention relates to a clamping device, in particular to an eccentric wheel-driven clamping fixture with a self-locking function. Background technique [0002] At present, the clamping device is widely used in all walks of life. The clamping device generally uses bolts to clamp the workpiece. When workers perform mass processing, the installation and removal of the workpiece requires repeated tightening and loosening of the universal machine tool fixture. Compressing the nut requires a lot of labor intensity, low production efficiency, and time-consuming and labor-intensive work. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provide an eccentric self-locking clamp, which is easy to operate, fast in clamping speed, high in efficiency, reasonable in design, large in pressing force, reliable in self-locking, and universal Strong performance, wide applica...
