Manually-controlled clamping device for flaky workpieces and use method of manually-controlled clamping device

Abstract

The invention discloses a manually-controlled clamping device for flaky workpieces and a use method of the manually-controlled clamping device. The clamping device comprises a base frame (9), two driving wheel components (700) and two clamping plates (8), wherein the two driving wheel components (700) are rotationally and symmetrically arranged at two sides of the base frame (9); the two clamping plates (8) are separately driven by the two driving wheel components (700) and are symmetrically arranged; each driving wheel component (700) comprises a spindle (79), an upper driving wheel (7) arranged at the upper end of each spindle (79), a lower driving wheel (5) arranged at the lower end of each spindle (79) as well as a push-pull vertical rod (71) which is fixedly connected between each upper driving wheel (7) and the corresponding lower driving wheel (5); and the push-pull vertical rod (71) of each driving wheel component (700) is hinged to the tail end of a protruding arm (61) of a corresponding push-pull sliding block (6).

Description

technical field [0001] The invention relates to the field of clamps, in particular to a manually controlled clamping device for sheet workpieces and a method for using the same. Background technique [0002] For the processing and testing of some sheet workpieces, it is often necessary to clamp the workpiece reliably. However, some current clamping devices are often complex in structure, and it is difficult to achieve an increased opening distance to meet the clamping and ease of loading and unloading of workpieces with different thicknesses and sizes. However, when some transmissions with a large opening distance are implemented through chain or belt transmission, it is often difficult to apply a large clamping force, and it also has a delay in the response to the operation or has a power transmission loss. Contents of the invention [0003] The object of the present invention is to provide a manually controlled clamping device for sheet workpieces and a method of use th...
