Abstract

The invention discloses a manipulator power assisting device. The manipulator power assisting device comprises a case, wherein the case is connected with a liquid inlet pipeline, a first pipeline and a second pipeline are arranged on the case, the first pipeline is connected to a driving mechanism, the second pipeline is connected to a braking mechanism, two elastic diaphragms are arranged in the first pipeline, through holes are formed in the centers of the elastic diaphragms, two spring bodies which are crossly connected are arranged between the spring diaphragms, an ellipsoidal buffer portion is arranged on the second pipeline, a plurality of baffles are arranged in parallel in the ellipsoidal buffer portion, a first skirt plate and a second skirt plate are respectively arranged between the liquid inlet pipeline and the first pipeline and between the liquid inlet pipeline and the second pipeline, a throttling valve is arranged on the first skirt plate, a notch is formed in one end of the second skirt plate, and the notch is located in one side of the first pipeline. The manipulator power assisting device can improve the defect of the prior art, obviously weaken the nonlinear distortion of the power assisting device and improve the power boosting accuracy.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to a manipulator assisting device. Background technique [0002] During the operation of the robotic arm, frequent start and stop actions are required. In the case of heavy load, it is necessary to use a booster device for driving. Chinese invention patent CN101201086B discloses a series pneumatic brake booster, which solves the problem of braking hysteresis. However, this structure has obvious nonlinear distortion during the boosting process, especially in the initial segment and the end segment. If it is used in precision equipment, it will affect the accuracy of its movement and positioning. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mechanical arm assisting device, which can solve the deficiencies of the prior art, significantly weaken the nonlinear distortion of the assisting device, and improve the as...
