Rotational multi-workpiece clamping and multi-station pneumatic clamp

Abstract

The invention discloses a rotational multi-workpiece clamping and multi-station pneumatic clamp. The clamp comprises a clamp body, a locating rotating mechanism and a clamping mechanism, wherein the clamp body comprises two vertical boards parallel to each other, and the two vertical boards are provided with the locating rotating mechanism and the clamping mechanism respectively and are connected with each other through a plurality of pull rods; the locating rotating mechanism comprises a driving air cylinder, an output shaft of the driving air cylinder is connected with a toothed bar located on one side of one vertical board, the vertical boards are evenly provided with a plurality of rotary shafts, each rotary shaft is connected with a cylindrical gear through a key, and each cylindrical gear is meshed with the toothed bar; the clamping mechanism comprises a plurality of clamping air cylinders which are respectively in transmission connection with a rolling jacking rod, each rolling jacking rod penetrates through the other vertical board, and a pressing block is fixed to the other end of each rolling jacking rod. The rotational multi-workpiece clamping and multi-station pneumatic clamp can effectively achieve the function of a numerically-controlled machine tool, improve machining efficiency of workpieces, and guarantee machining quality.

Description

technical field [0001] The invention belongs to the field of fixture design of numerical control machine tools, and in particular relates to a multi-piece clamping and multi-station rotatable pneumatic fixture. Background technique [0002] The field of modern mechanical numerical control machining is more and more oriented towards mass customization and mass-scale production. In the manufacturing industries such as automobiles, there are often various polyhedral multi-station processing requirements for valve bodies, pump bodies, and cylinder blocks. Although the three-axis and five-axis machining centers can realize multi-station machining of workpieces in one clamping, they are not suitable for mass production mode. The use of three-axis machining centers with good cost performance requires multiple clamping of workpieces to complete multi-station surface processing, resulting in loading and unloading problems. Many times and troublesome operation lead to low processing e...

[0002] The field of modern mechanical numerical control machining is more and more oriented towards mass customization and mass-scale production. In the automobile and other manufacturing industries, there are often various polyhedral multi-station processing requirements for valve bodies, pump bodies and cylinder blocks. Although the three-axis and five-axis machining centers can realize multi-station machining of workpieces in one clamping, they are not suitable for mass production mode. The use of three-axis machining centers with good cost performance requires multiple clamping of workpieces to complete multi-station surface processing, resulting in loading and unloading problems. Too many times and cumbersome operations lead to low processing efficiency, and the cumulative error caused by multiple clampings affects the processing quality of the workpiece
