Pneumatic installing and clamping chuck

Abstract

The invention relates to a pneumatic installing and clamping chuck, which comprises a connecting disc, a chuck outer sleeve, a chuck inner sleeve, a separation disc, an installing disc, a clamping device, a guide device, a conversion device and a driving device, wherein one end of the chuck outer sleeve is provided with the connecting disc; the other end of the chuck outer sleeve is provided withthe installing disc; the chuck inner sleeve in coaxial arrangement with the chuck outer sleeve is also arranged between the connecting disc and the installing disc; a guide device is arranged on the installing disc; the clamping device is arranged at one side of the outside of the guide device; the conversion device is arranged at one side of the inside; the driving device is arranged between theconversion device and the connecting disc; the separation disc is arranged is arranged between the conversion device and the driving device; the conversion device converts the axial rotation into theradial movement of the clamping device; the clamping device comprises a first clamping device and a second clamping device. The circumference movement of the conversion device is converted into the radial movement of the clamping device; two devices are installed, so that the clamping on workpieces with irregular cross sections can be realized; the universal performance of the pneumatic installingand clamping chuck can be improved.

Description

technical field [0001] The invention belongs to the technical field of pneumatic clamps, and in particular relates to a pneumatic clamping chuck. Background technique [0002] The chuck is a mechanical device used to clamp the workpiece on the machine tool. It uses the radial movement of the movable jaws evenly distributed on the chuck body to clamp and position the workpiece. It is a precision clamping device. [0003] Ordinary four-jaw chucks have a small clamping range, unclamping is not stable enough, and the precision is not enough. Most of them can only clamp regular workpieces that are symmetrical about the center, such as round or square, and the types of clamping workpieces are very limited. Contents of the invention [0004] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art, and to provide a pneumatic clamping chuck, which can obtain a certain elastic clamping force through the drive of the cylinder, and at th...
