Clamp

Abstract

The invention discloses a clamp. The clamp is characterized in that a block body is machined to form a rigid component and a movable component with a preset distance reserved between the rigid component and the movable component; a clamping hole allowing a to-be-clamped rod piece to extend between the rigid component and the movable component is formed in the head end; at least one elastic element connected between the rigid component and the movable component is arranged at the other end, opposite to the clamping hole, of the block body; furthermore, a first chain belt perpendicularly connected between the rigid component and the movable component is integrally formed at the position, opposite to the inner side of the clamping hole, of the block body, and a second chain belt horizontally connected to the rigid component is integrally formed at the joint of the first chain belt and the movable component. Therefore, the connection between the movable component and the rigid component can be realized under the action of the first chain belt and the second chain belt, and the movable component is limited to swing around the joint, serving as a pivot, of the first chain belt and the second chain belt, so that a relatively stable and reliable operating effect can be achieved.

Description

technical field [0001] The invention relates to a clamp, in particular to a clamp that can be used to produce a fine positioning and clamping effect on a rod. Background technique [0002] Press, the development of micro-cutting technology mainly depends on the support of micro-cutting tool technology; in principle, the tool suitable for micro-cutting should at least have: small local feature scale, sharp cutting edge, good surface quality, high strength, good rigidity, And good wear resistance and other characteristics, and its requirements for its own dimensional accuracy and accuracy are relatively high. [0003] Therefore, in the process of processing and grinding the body of the micro-cutting tool, it is especially necessary to clamp and fix the body of the micro-cutting tool, so as to avoid affecting the dimensional accuracy of the micro-cutting tool due to the movement of the body of the micro-cutting tool. In addition, in order to maintain the processing capacity of...

Problems solved by technology

[0008] In the clamp sleeve disclosed in Taiwan Patent Publication No. 200639006, the bending and deformation of the entire elastically deformable wall 13 causes the movable element 12 to move toward the rigid element 11 relative to the end forming the jaw 14. Pressing against, or causing the movable element 12 to displace in the direction opposite to the rigid element 11 relative to the end forming the jaw 14, but during the swinging process of the movable element 12, the fulcrum of the movable element 12 will swing with it Different degrees fall on different parts of the entire elastically deformable wall 13, making the swing effect generated by the movable element 12 extremely unstable, so that the reliability of the clamp sleeve is greatly reduced
