Abstract

The invention discloses a round eccentric pressing plate, and particularly relates to the field of clamps. The round eccentric pressing plate comprises a fixing mechanism and a driving mechanism, the fixing mechanism comprises a base and a fixing screw fixedly connected inside the base, and the driving mechanism comprises a pressing plate, an eccentric wheel, a handle, a slope backing plate and driving screws. One end of the pressing plate is hinged to the eccentric wheel, a protrusion is arranged on the lower surface of the other end of the pressing plate, the eccentric wheel is fixedly connected with the handle, the driving screws are clamped to the base, and the slope backing plate is fixedly connected with the driving screws. A hole is formed in the pressing plate, the fixing screw penetrates through the hole, an upper gasket is arranged between the head of the fixing screw and the upper surface of the pressing plate, a lower gasket is arranged on the lower surface of the pressing plate, and a spring part is arranged between the lower gasket and the base. A sliding groove is formed in the slope backing plate, and the eccentric wheel slides inside the sliding groove. The driving screws drive the slope backing plate to move in the horizontal direction of the base. According to the scheme, workpieces of different sizes can be clamped, and the problem that after the workpieces are machined, quality is poor is solved.

Description

technical field [0001] The invention relates to a clamp, in particular to a circular eccentric pressing plate. Background technique [0002] The device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to accept construction or inspection, also known as fixture. For example, welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc., among which machine tool fixtures are the most common. When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as the size, geometric shape, and position accuracy with other surfaces specified in the drawing, the workpiece must be installed and clamped firmly before processing. [0003] With the development of industry, more and more workpieces are processed, and in many processing methods, the workpiece must be positioned and clamped. The workpiece clamping makes the workpiece ...
