Compact annular axial high-precision positioning clamping mechanism and its use and manufacturing method

Abstract

The invention discloses a compact type annular axial high accuracy positioning and clamping mechanism, and a using and manufacturing method thereof. The clamping mechanism comprises a base, a sealing ring, an annular clamping plate and a revolved body, wherein the annular clamping plate is fixed on the revolved body or the base through sunk screws; when the revolved body is located to be stopped at any position, liquid and gas can be pressed in an annular sealing cavity, a sealed piston device can generate a certain displacement in the axial direction, the axial force is uniformly acted on the annular face of the annular clamping plate, and the annular clamping plate is pressed to be deformed, so that friction torque is generated to carry out angle positioning and clamping on the revolved body; the revolved body cannot be axially displaced or twisted when the positioning and the clamping occur, so that high accuracy positioning and clamping can be realized; when the liquid pressure and the gas pressure are completely unloaded, the annular clamping plate is immediately rebounded to be at the initial situation, and the revolved body can be released and revolved at will.

Description

technical field [0001] The invention relates to a positioning and tightening mechanism that can be widely used in automatic equipment such as machine tools, fixtures, engineering machinery, etc. that have the function requirements of rotary positioning and clamping at any angle, and specifically relates to a compact annular axial high-precision positioning and clamping mechanism and its use and manufacturing methods. Background technique [0002] The application of the positioning and clamping mechanism in the rotary axis can not only provide high positioning accuracy for the specified angle machining of the rotary axis, but also disperse the force of the transmission mechanism during positioning and processing, and transmit the force directly to the base body, so that the drive system and transmission mechanism be released, so as to ensure that the rotary shaft has high transmission accuracy and life. Therefore, rational design of the positioning and clamping mechanism has ...
