Abstract

The invention relates to a rotary driving device for measuring and positioning, a fixed block and a movable block are arranged in an annular gap between a cylinder body and a rotating shaft, the annular gap is divided into two oil cavities between the fixed block and the movable block in the circumferential direction by the fixed block and the movable block, and two oil holes used for being communicated with the two oil cavities respectively are formed in the cylinder body. The oil hole is divided into two branch holes on the oil cavity side, the opening of the first branch hole is formed in the circumferential side wall, corresponding to the corresponding oil cavity, of the fixed block, the opening of the second branch hole is formed in the inner end wall, corresponding to the corresponding oil cavity, of the cylinder body and located in the swing area of the movable block, and a one-way valve only allowing media to flow into the corresponding oil cavity is arranged in the first branch hole. The invention also relates to a positioning measurement system adopting the rotation driving device. The driving device achieves buffering in the starting and stopping process, is simple in structure, convenient to install, reliable and durable, and facilitates improvement of efficiency and reliability of machine tool measurement positioning or other application equipment.

Description

technical field [0001] The invention relates to a rotary driving device for measurement and positioning, which can be mainly used for measurement and positioning and rotary driving in other occasions. Background technique [0002] Domestic and foreign machine tool manufacturers, especially in the positioning measurement drive mechanism of grinding machines, generally use the drive structure forms of positioning measurement as linear drive mode and rotary drive mode. The linear drive mode provides linear drive power through hydraulic cylinders or pneumatic cylinders. Guaranteed by the guidance of components such as linear guide rails, the measurement components are pushed to perform positioning measurement. The rotary drive method is to provide rotary drive force through the vane swing cylinder or the rack and pinion mechanism to convert linear motion into rotary motion to provide rotary drive force to drive the measurement components for positioning. Measurement. There is n...
