Cam clamping device

Abstract

The invention discloses an oblique wedge clamping device, which has light and novel design, simple and practical principle, large clamping contact surface, light total weight, few components and good processability. The technical solution is: the device includes a handle, a wedge, a fixing frame, a fixing piece, and a stud, wherein the handle is installed at one end of the stud, and the other end of the stud enters the wedge hole of the wedge through the threaded hole of the fixing frame , the fixing part is installed in the long groove of the fixing frame, the fixing part has a sloped square hole, the oblique wedge is installed in the oblique square hole of the fixing part, and the oblique surface of the oblique wedge and the oblique surface of the oblique square hole of the fixing part fit together.

Description

technical field [0001] The invention relates to a clamping device, in particular to a wedge clamping device. Background technique [0002] The clamping device is used for clamping between two parts. For the traditional clamping device, for the clamping between two parts at 90° to the direction of force (clamping operation in the form of perforation), the clamping The direction of force prevents access to tools such as wrenches. Moreover, the geometric dimensions of the two parts are relatively large, especially the flat parts, so that hands or tools cannot reach the clamping position. [0003] For example, the oblique wedge clamping device that applies force to the slide block through the inclined roller to drive the pressure plate on the slide block to move up and down to clamp the workpiece is only suitable for small workpieces, and its disadvantage is that the force arm of the pressure plate should not exceed long. As for the wedge clamping device that tightens the bol...

[0002] The clamping device is used for clamping between two parts. For the traditional clamping device, for the clamping between two parts at 90° to the direction of force (clamping operation in the form of perforation), the clamping The direction of force makes it impossible to reach into the wrench type tool

Moreover, the geometric dimensions of the two parts are relatively large, especially for flat parts, and hands or tools cannot reach into the clamping position.

[0003] For example, the oblique wedge clamping device that applies force to the slide block through the inclined roller to drive the pressure plate on the slide block to move up and down to clamp the workpiece is only suitable for small workpieces, and its disadvantage is that the force arm of the pressure plate should not exceed long

For the double wedge clamping device, which utilizes the movement of the two jacks on the double wedge along the inclined plane to increase the axial distance between them to clamp the parts, the disadvantage is that the clamping force is not on a straight line, thus generating torque
