High-precision multi-section sleeve cylinder for pharmaceutical machinery

Abstract

The invention relates to the technical field of sleeve cylinders, in particular to a high-precision multi-section sleeve cylinder for pharmaceutical machinery. The cylinder barrel comprises a large cylinder barrel body and a small cylinder barrel body, end covers are arranged at the ends of the small cylinder barrel body and the large cylinder barrel body, and an anti-rotation shaft is arranged in the small cylinder barrel body. One end of the anti-rotation shaft is fixedly connected with a piston rod; the outer side of the large end cover is fixedly provided with a mounting flange for mounting, and the outer side of the large cylinder barrel is provided with a telescopic power assembly. The transition block is arranged outside the large end cover, the transition block is connected with the rear end cover at the end of the large cylinder barrel through the rodless cavity oil inlet pipe, and after the transition block is connected with the outside, oil inlet is controlled so that stretching and retracting of the large cylinder barrel and the small cylinder barrel can be achieved. The balance valve can balance the pressure of the telescopic power assembly, and stall when the piston rod extends out is prevented. A valve adjusting assembly is arranged on the rear end cover and comprises a sequence valve and a throttling valve, and the throttling valve ensures that the extending speed and the retracting speed of the small cylinder are the same as those of the large cylinder and is matched with a displacement sensor to ensure the stretching and retracting precision.

Description

technical field [0001] The invention relates to the technical field of sleeve cylinders, in particular to a high-precision multi-section sleeve cylinder for pharmaceutical machinery. Background technique [0002] Existing pharmaceutical machinery uses conventional hydraulic cylinders, which usually face the problem of low precision; adding auxiliary accessories such as displacement sensors or proximity switches, although the precision is improved, it still cannot solve the problem of installation in a small space. [0003] Therefore, the existing mechanical sleeves cannot meet the two requirements of installation in a narrow space and high precision at the same time. Contents of the invention [0004] The object of the present invention is to solve the problems in the background technology, and propose a high-precision multi-section sleeve cylinder for pharmaceutical machinery that can be installed in a narrow space. [0005] The technical solution of the present inventio...
