Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, the present invention discloses a cylinder structure based on magneto-rheological technology, including an inner sleeve 16, a built-in piston 18, an outer piston 25, a connecting rod 19 and a damping device 23, wherein:

[0029] The space inside the inner sleeve 16 is divided into a first cavity and a second cavity by a partition arranged transversely to the axial direction of the inner sleeve 16 in the inner sleeve 16, and the second cavity is arranged near the side wall of the partition There are vent holes 21, and the outer side of the inner sleeve 16 is spirally wound with a wire 20 communicating with the power supply. The inner sleeve 16 is made of magnetically conductive material, and the end surface of the second cavity away from the partition is provided with an air The source hole, the first cavity is filled with ma...

Abstract

The invention discloses an air cylinder structure based on the magneto-rheological technology. A partition plate which is transversely arranged in an inner sleeve relative to the axial direction of the inner sleeve divides the space inside the inner sleeve into a first cavity and a second cavity, the side wall of the portion, close to the partition plate, of the second cavity is provided with ventholes, a wire connected with a power source is spirally wound on the outer side of the inner sleeve, the end face, away from the partition plate, of the second cavity is provided with a gas source hole connected with a gas source, the first cavity is filled with magneto-rheological fluid, a connection rod is arranged in the axial direction of the inner sleeve and penetrates through the partitionplate, one end of the connection rod is connected with a piston arranged inside the second cavity, the other end of the connection rod stretches out of the end face, away from the partition plate, ofthe first cavity to be connected with a piston arranged outside, and a damping device is installed in the first cavity and fixedly connected with the connection rod. A stop block is added into an aircylinder, the improved technical scheme is carried out on the air cylinder structure based on the magneto-rheological technology, the air cylinder output pressure is controllable, the throwing hit rate of the robot is improved, and mechanical collision and energy loss are reduced.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a cylinder structure based on magneto-rheological technology and a controllable throwing robot. Background technique [0002] The China Robot Competition is currently the highest-level and largest robot competition in China. The basketball robot project is an education and competition project that has emerged in recent years. This project provides a multi-field research on robot motion control, robot vision and artificial intelligence. Standard test platform. As a common pneumatic actuator, the cylinder is inevitably involved in the robot system. It will be a very meaningful topic to study how to improve the design of the cylinder structure for a specific robot application field. [0003] The most basic structure of the cylinder is a built-in piston, an external piston, and a connecting rod connecting the inner and outer pistons. The working principle is to press the gas compress...
