Bidirectional clamping device

Abstract

The invention relates to a clamping device, in particular to a bidirectional clamping device, which comprises a clamp body, a sleeve, an extrusion knob, an upper clamping block, a right clamping block, a swinging arm and a sliding shaft, wherein the sleeve is fixedly arranged on the clamp body; the extrusion knob serves as a force application device; the upper clamping block and the right clamping block are used for pressing the surfaces of a workpiece; the tail end of the right clamping block is a wedge surface; the upper clamping block is driven by the swinging arm to clamp the workpiece; the tail part of the swinging arm is hinged to the clamp body; the upper clamping block is clamped with the middle part of the swinging arm; the end of the swinging arm is a U-shaped end; the right clamping block is driven by the sliding shaft to clamp the workpiece; a wedge hole is formed in the middle part of the sliding shaft, and is in sliding fit with the wedge surface of the right clamping block in the sleeve; a shaft shoulder capable of preventing the sliding shaft from being separated from the sleeve is arranged at the tail end of the sliding shaft; the upper end of the sliding shaft is hinged with one end of a rotating rod; and the other end of the rotating rod is connected with the end of the swinging arm by the extrusion knob in an extrusion way. According to the technical scheme, the bidirectional clamping device has a bidirectional clamping function, and is simple in structure.

Description

Technical field [0001] The invention involves a clamping device, which specifically involves a two -way clamping device. Background technique [0002] During the processing of mechanical processing, the positioning and clamping of the processing workpiece are essential. The positioning of the workpiece can ensure the accuracy of the processing, and the clamping can prevent accidents from flying during the processing process.Most of the existing clamping devices are one -way clamping. During the processing process, due to vibration or other external forces, the location of the workpiece may be offset.Clamping the workpiece, the device structure must be relatively complicated, and the common clamping device has the following shortcomings: 1. Using one -way clamping, the positioning of unstable positioning may generate offset and cause dislocation.Increased installation, disassembly, and operation.

Problems solved by technology

Most of the existing clamping devices are one-way clamping. During the processing process, due to vibration or other external forces, the position of the workpiece may shift, and the positioning is unstable, so that the processed workpiece cannot meet the processing requirements. Clamping the workpiece, the structure of the device must be relatively complicated, and the common clamping device has the following disadvantages: 1. Using one-way clamping, unstable positioning may cause offset and misalignment, and even the workpiece will fly out causing danger; 2. The structure of the device is complex, Inconvenient installation, disassembly and operation
