Segmented booster linear motion device

Abstract

The invention provides a segmented force-increasing type linear motion device comprising a cylinder barrel, a partition plate, a front piston, a rear piston, stators and a rotor. The partition plate is fixedly arranged in the cylinder barrel, and the partition plate is provided with a piston hole; the front piston is slidably arranged at the position, at the first end of the partition plate, in the cylinder barrel, and the first end of the front piston is fixedly connected with a front piston rod; the rear piston is slidably arranged at the position, at the second end of the partition plate, in the cylinder barrel, the first end of the rear piston is fixedly provided with a rear piston rod, and the rear piston rod and the piston hole are correspondingly arranged; and the stators are arranged on the inner side wall of the cylinder barrel in a surrounding manner, the rotor is arranged between the stators, and the first end of the rotor is fixedly connected to the rear piston. The segmented force-increasing type linear motion device comprises multi-stage linear advancement and resetting processes, has the advantages of being high in working speed and large in linear driving force, hashigh dynamic rigidity, is stable in pneumatic transmission, and overcomes the defects of use of single linear motor or cylinder.

Description

technical field [0001] The invention relates to the technical field of linear drive devices, in particular to a segmented booster linear motion device. Background technique [0002] A linear motor is a drive device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. The linear motor can be considered as a structural deformation of the rotary motor. It can be seen as a rotary motor that is cut along its radial direction and then flattened to evolve. With the rapid development of automatic control technology and microcomputers, higher requirements are put forward for the positioning accuracy of various automatic control systems. Devices are far from meeting the requirements of modern control systems. For this reason, many countries in the world are researching, developing and applying linear motors, making the application fields of linear motors more and more extensive. [0003] However, the dynamic ri...

Problems solved by technology

[0006] The present invention provides a segmented power-increasing linear motion device, the purpose of which is to solve the problem that the existing linear motor has low dynamic rigidity, can not play the role of buffering and damping, cannot self-lock, and the thrust is not large enough. A single cylinder usually needs to be combined with air pressure The air pressure may change during the pneumatic transmission process, and the stability is not high.
