An electric clamping device for a sheet workpiece and its application method

Abstract

Provided are an electric clamping device for a piece-shaped workpiece and a using method thereof. The clamping device comprises a base frame (9), two driving wheel components (700) rotatably symmetrically installed on the two sides of the base frame (9) and two symmetrically arranged clamping plates (8) driven by the two driving wheel components (700), wherein each driving wheel component (700) comprises a rotating shaft (79), an upper driving wheel (7) fixedly installed at the upper end of the rotating shaft (79), a lower driving wheel (5) fixedly installed at the lower end of the rotating shaft (79) and a push-pull vertical rod (71) fixedly connected between the upper driving wheel (7) and the lower driving wheel (5). The push-pull vertical rod (71) of each driving wheel component (700) is hinged to the tail end of a protruded arm (61) of a corresponding push-pull sliding block (6).

Description

technical field [0001] The invention relates to the field of fixtures, 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 workpiece and its usage method, which can overcom...
