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.
