Delta parallel-connection mechanical hand for teaching

Abstract

The invention discloses a Delta parallel-connection mechanical hand for teaching. The Delta parallel-connection mechanical hand comprises a Delta type parallel-connection mechanical hand machine body and a rack, the Delta type parallel-connection mechanical hand machine body comprises a detachable tail-end execution element, a plurality of servo motors and a plurality of sets of mechanical arms connected with the tail-end execution element. The servo motors correspond to the mechanical arms in a one-to-one mode, and one set of mechanical arms is driven by one servo motor; the servo motors are respectively and fixedly arranged on the top of the rack, and are connected with the corresponding mechanical arms respectively; each mechanical arm is mainly composed of an upper arm body and a lower arm body, one end of each upper arm body is connected with the corresponding servo motor, the other end of the upper arm body is connected with one end of the corresponding lower arm body through a first fisheye bearing with three freedom degrees, and the other ends of the lower arm bodies are connected with the tail-end execution element through second fisheye bearings with three freedom degrees. On the premise of greatly reducing the manufacturing cost, the original ecological Delta parallel-connection mechanical hand is built for a student to be learnt and developed.

Description

technical field [0001] The invention relates to the technical field of Delta parallel robots, in particular to a Delta parallel manipulator used for teaching. Background technique [0002] Delta parallel robot is currently the most successful parallel robot in commercial application, and has a very broad application prospect in all walks of life. After more than 20 years of development in foreign countries, its structure and control system have been very mature, and are widely used in electronics, food and medicine industries to complete a large number of repetitive operations such as grabbing, sorting and packaging. In my country, both the application and development of Delta parallel robots have just started in 2010. The production of Delta parallel robots is just in its infancy. The performance is lower than that of foreign robots, and the awareness of domestic users is far from enough. The narrow market of industrial manipulators seriously hinders the development of indu...

Problems solved by technology

In my country, both the application and development of Delta parallel robots have just started in 2010. The production of Delta parallel robots is just in its infancy. The performance is lower than that of foreign robots, and the awareness of domestic users is far from enough. The narrow market of industrial manipulators seriously hinders the development of industrial automation in China

[0003] At present, the manipulators on the market are expensive, and it is difficult for colleges and universities to afford the price, so that students have the opportunity to get in touch with manipulators and allow students to develop and learn, so that students have no contact in this era of highly developed industrial automation. And the opportunity to learn Delta parallel manipulator, besides, there are very few Delta parallel manipulators specially used for teaching
