Pipe clamping device

Abstract

The invention discloses a pipe clamping device. The pipe clamping device comprises a fixed clamping block, a movable clamping block, a swinging arm and a folding fixed arm, wherein the fixed clamping block and the movable clamping block are used for clamping a pipe; one end of the swinging arm is hinged to one end of the fixed arm; the other swinging end of the swinging arm is connected with the other end of the fixed arm through a clamping mechanism in a locking way; the fixed clamping block is fixedly connected to the fixed arm; the movable clamping block is hinged to the swinging arm; the clamping mechanism comprises a screw, a spring baffle and a spring; the spring baffle is fixedly connected to the fixed arm; one end of the screw is positioned on the swinging arm; a body of the screw penetrates through the spring baffle and is sleeved with the spring; an adjusting nut is screwed at the other end of the screw and is used for extruding the spring on the spring baffle so as to tightly pull the swinging arm toward the fixed arm; pin holes are formed in one swinging end of the swinging arm and are reserved installation holes of an unlocking mechanism which is used for pushing the swinging arm away from the fixed arm. The pipe clamping device has the integrated advantages of a screw clamping mechanism and a lever mechanism, and is simple and compact in structure and convenient to install and operate.

Description

(1) Technical field: [0001] The invention relates to the field of mechanical equipment clamping, in particular to a pipe fitting clamping device which can provide clamping force by a mechanical mechanism or a hydraulic mechanism. (2) Background technology: [0002] Clamping devices are used in many fields, and clamping devices with different clamping shapes are used for different purposes. Analyzing the clamping schemes in various fields, the parts that play a basic clamping role in the clamping device include wedges, spirals, eccentrics, levers, etc., and the clamping device composed of them. [0003] For example, the wedge clamping device uses the clamping force generated by the movement of the wedge to clamp the parts. It has a simple structure and is easy to operate, but the self-locking performance of the wedge clamping device is not good, and it may fail when there is a large impact and vibration. danger; the screw clamping device adopts screw direct clamping and othe...

Problems solved by technology

[0003] For example, the wedge clamping device uses the clamping force generated by the movement of the wedge to clamp the parts. It has a simple structure and is easy to operate. However, the self-locking performance of the wedge clamping device is not good, and it may fail when there is a large impact and vibration. danger; the screw clamping device adopts screw direct clamping and other components to realize the clamping mechanism of the workpiece. This clamping mechanism has the advantages of simple structure, strong versatility, unlimited stroke, reliable clamping and convenient manufacture. Tightening and loosening the workpiece takes time and effort

The eccentric clamping device is a mechanism that directly or indirectly clamps the workpiece with an eccentric member. The mechanism moves quickly, but the clamping stroke is limited by the eccentric distance, the clamping force is relatively small, and the self-locking performance is poor.

[0004] The clamping device mentioned above is generally only suitable for occasions where the dimensional tolerance of the workpiece in the clamping direction is small and the vibration is not large during processing.
