Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Embodiment 1
As shown in figures 1 and 3, the present embodiment is related to a kind of adjustable gravity balance device, including Vertical Rack 1, institute
It states Vertical Rack 1 and is equipped with a pair of of linear guide 2, linear guide 2 is equipped with sliding block 14, is fixed with carrier platform 8 on sliding block 14；
The carrier platform 8 is equipped with the first mover coil component 7, and accordingly, the Vertical Rack 1 is equipped with the first stator permanent magnet
Body 13, the first mover coil component 7 and the first stator permanent magnet 13 driving carrier platform 8 are gone up and down；
The carrier platform 8 is fixed with the second mover coil component 16 being arranged in pairs, and accordingly, Vertical Rack 1 is fixed with
The second stator permanent magnet 15 being arranged in pairs, the second mover coil component 16 and the second stator permanent magnet 15 driving carrier platform 8 are flat
Weighing apparatus load.
The second mover coil component 16 is vertical with the magnetic induction line of the second stator permanent magnet 15.
Second stator permanent magnet 15 uses U-shaped magnet, on U-shaped magnet fixed magnet pedestal 9；In the pole N of U-shaped magnet
It is arranged in parallel up and down with the pole S relative to 1 surface of Vertical Rack；The N for the second stator permanent magnet 15 being arranged in pairs on Vertical Rack 1
Pole and the pole S up and down direction are opposite.
The corresponding sliding block 14 of the linear guide 2 is equipped with briquetting 10 in inside.
As shown in Fig. 2, the range of the corresponding carrier platform 8 of the Vertical Rack 1 is equipped with upper lower bumper 12, buffer 12
