Abstract

The invention discloses a remote movement center mechanism of gravity balance, which comprises an (A) connecting bar, a (B) connecting bar, a (C) connecting bar, a (D) connecting bar, an (E) connecting bar, an (F) connecting bar, an (A) balance weight, a (B) balance weight, a (C) balance weight, an (A) clamping piece component, a (B) clamping piece component, a (C) clamping piece component, a base, a support, a connecting piece, a cross bar and a vertical bar. The support is installed on the base; the (A) connecting bar and the (B) connecting bar are placed in parallel; the (C) connecting bar and the (D) connecting bar are placed in parallel; the ends of the parallel connecting bars are respectively and moveably connected with the (F) connecting bar and the connecting piece; a tool is arranged at the lower end part of the connecting piece; the (A) balance weight is installed the regulation section of the (A) balance weight of the (F) connecting bar, and the position of the (A) balance weight on the regulation section of the (B) balance weight is regulated through the (B) clamping piece component; and the (C) balance weight is installed on the vertical bar and position of the (C) balance weight on the vertical bar through the (C) clamping piece component. Through the mechanism of the invention, the tool can rotate around a virtual rotation center (O) in the space, and can keep the self gravity balance in each movement position.

Description

technical field [0001] The invention relates to a weight-balanced remote motion center mechanism. Background technique [0002] A component can rotate around a fixed point in space. There is no actual rotating joint at this fixed point, and the virtual fixed point is at the far end of the mechanism. This mechanism is called a virtual Remote Center of Motion (RCM) )mechanism. [0003] The gravity balance (or static balance) of the mechanism means that the mechanism can maintain a balanced state in any configuration without driving force, and the whole system can operate as if in a zero-gravity environment. This means that under the action of pure gravity, the mechanism can stop at any phase of the active part. The mechanism in which the total center of mass of the moving components remains stationary is called a gravity balance (static balance) mechanism. Gravity balance is an important issue in mechanism research. Its purpose is to reduce the driving force of the operatin...

Problems solved by technology

In general, due to the configuration dependence of the gravitational properties of the mechanism, only a partial gravitational balance of the mechanism can generally be achieved
