Telescopic cross arm of hydraulic large-sized mechanical hand

Abstract

The invention discloses a telescopic cross arm of a hydraulic large-sized mechanical hand. The telescopic cross arm of the hydraulic large-sized mechanical hand comprises a telescopic sliding table, a foundation board, a guiding sliding rod, a support block, a telescopic oil cylinder, a telescopic positioner and a counter weight device, the foundation board is fixed to the telescopic sliding table, the guiding sliding rod is arranged inside the telescopic sliding table in a penetrating mode, the right end of the guiding sliding rod is connected with the support block, the support block is connected with a piston rod of the telescopic oil cylinder, the telescopic positioner is arranged at the left end of the guiding sliding rod, a measuring rod of the telescopic positioner is connected to the counter weight device through a connecting piece, the counter weight device is fixed to the left end of the foundation board, and the telescopic oil cylinder is installed on the upper plane of the foundation board. By means of the mode, the telescopic cross arm of the hydraulic large-sized mechanical hand is under pure hydraulic drive, each movable joint is large in movable torque, the telescopic cross arm of the hydraulic large-sized mechanical hand can work in severe industrial environment, the requirements for protecting levels are lower, the working force of the telescopic cross arm of the hydraulic large-sized mechanical hand is much higher than that of electrically-driven mechanical hands of the same level, and the cost of the telescopic cross arm of the hydraulic large-sized mechanical hand is much lower than that of the electrically-driven mechanical hands of the same level.

Description

technical field [0001] The invention relates to machining tools, in particular to a telescopic horizontal arm of a hydraulic large manipulator. Background technique [0002] In the modern industrial production of hungry machinery, a large number of automated machinery replaces workers to complete work in harsh environments. However, most of the industrial manipulators in the current industrial assembly line are driven by electricity, which has certain limitations, high cost, and high protection requirements. The price of large electric-driven manipulators can be said to be very high. Some roughing applications are unacceptable in the industry, and the environment in the roughing industry is a bit harsh for electric drive manipulators. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a telescopic cross arm of a hydraulic large-scale manipulator, which is driven by pure hydraulic pressure, and each movable joi...
