Electric clamping device used for sheet workpieces and use method of electric clamping device

Abstract

The invention provides an electric clamping device used for sheet workpieces and a use method of the electric clamping device. The clamping device comprises a base frame (9), two drive wheel parts (700) and two clamping plates (8). The drive wheel parts (700) are symmetrically installed on the two sides of the base frame (9) in a rotatable manner. The clamping plates (8) are driven by the two drive wheel parts (700) and symmetrically arranged. Each drive wheel part (700) comprises a rotating shaft (79), an upper drive wheel (7) fixedly installed at the upper end of the rotating shaft (79), a lower drive wheel (5) installed at the lower end of the rotating shaft (79), and a push-pull vertical rod (71) fixedly connected between the upper drive wheel (7) and the lower drive wheel (5). The push-pull vertical rod (71) of each drive wheel part (700) is hinged to the tail end of a protruding arm (61) of a corresponding push-pull slide block (6).

Description

technical field [0001] The invention relates to the field of clamps, in particular to an electric 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 an electric clamping device for a sheet-shaped workpiece and its usage method, which can ov...
