Technical field

The invention belongs to mechanical equipment technical field, relate to a kind of weighing device for the artificial crystal growth process.

Background technology

Laser crystals (YAG), sapphire crystal (Al ₂O ₃) etc. artificial lens be the main raw of making laser apparatus, semiconductor lighting, high-end window, the preparation of this type of artificial lens (growth) is normally in the furnace chamber of cleaning, under the protective atmosphere condition, by well heater starting material are melted, then, by the seed crystal guiding, grow desirable monocrystalline with the method that upwards lifts; Go out high-quality qualified monocrystalline in order to stablize Fast Growth, need to accurately control the diameter of crystal, to reach the needs of subsequent technique.

The diameter control of crystal of the prior art adopts on lower Weighing method or the electric motor built-in methods such as Weighing mechanism, and complex structure, control accuracy is low, installation and debugging are difficult, can not satisfy the growth of high-quality artificial lens.

Summary of the invention

The purpose of this invention is to provide a kind of weighing device for the artificial crystal growth process, solved that complex structure of the prior art, control accuracy are low, the installation and debugging hard problem.

The technical solution adopted in the present invention is, a kind of weighing device for the artificial crystal growth process, be installed with bearing support at slide, be set with turning axle in the bearing of bearing support, turning axle has axis through-hole, turning axle is connected with motor-driven, and the turning axle upper end is fixedly connected with rotating disk; Be installed with support plate on the rotating disk, be installed with LOAD CELLS on the support plate, the cantilever termination of LOAD CELLS is provided with transition seat, and transition seat is downward and seed shaft is hinged, and seed shaft passes from the turning axle axis through-hole downwards; Also be installed with seal closure on the rotating disk, the upper surface of seal closure is provided with seal socket;

The upper surface of described seal closure also is provided with the brush ring, and the rotating ring of brush ring is arranged on upper surface and the position corresponding with LOAD CELLS of seal closure, and the fixed ring of brush ring is fixedly mounted on the slide.

The invention has the beneficial effects as follows: simple in structure, easy for installation, precision is high, has improved high-quality, the large-scale production of artificial lens.

Description of drawings

Fig. 1 is the structural representation that the present invention is used for the weighing device of artificial crystal growth process.

Among the figure, 1. bearing support, 2. turning axle, 3. seed shaft, 4. motor, 5. slide, 6. retaining plate, 7. sealing-ring one, 8. rotating disk, 9. sealing-ring two, 10. straight pin, 11. seal sockets, 12. seal closure, 13. brush rings, 14. transition seats, 15. LOAD CELLS, 16. support plates.

Embodiment

With reference to Fig. 1, weighing device for the artificial crystal growth process of the present invention, its structure is, be installed with bearing support 1 at slide 5, be set with turning axle 2 in the bearing of bearing support 1, turning axle 2 has axis through-hole, and turning axle 2 is in transmission connection with motor 4, turning axle 2 upper ends are fixedly connected with rotating disk 8, and the contact surface between turning axle 2 and the rotating disk 8 is provided with sealing-ring 29; Be installed with support plate 16 on the rotating disk 8, be installed with LOAD CELLS 15 on the support plate 16, the cantilever termination of LOAD CELLS 15 is provided with transition seat 14, and transition seat 14 is hinged by straight pin 10 and seed shaft 3 downwards, and seed shaft 3 passes from turning axle 2 axis through-holes downwards; Also be installed with seal closure 12 on the rotating disk 8, contact surface between seal closure 12 and the rotating disk 8 is provided with sealing-ring 1, support plate 16, LOAD CELLS 15, transition seat 14, straight pin 10 all are in seal closure 12 inner chambers, and the upper surface of seal closure 12 is provided with seal socket 11; The upper surface of seal closure 12 also is provided with brush ring 13, the position that the upper surface that the rotating ring of brush ring 13 is arranged on seal closure 12 and LOAD CELLS 15 are corresponding, and the fixed ring of brush ring 13 is fixedly mounted on the retaining plate 6, and retaining plate 6 is fixedly mounted on the slide 5;

The signal transmission of LOAD CELLS 15 realizes by seal socket 11, and by the 13 realization signal outputs of brush ring, whole Weighing mechanism is followed slide 5 and moved together.
