Description

Technical Field

[0001] The utility model relates to the technical field of single crystal furnace rod extraction tooling, in particular to a single crystal furnace crystal rod extraction tooling. Background Art

[0002] In the process of single crystal silicon production, the quartz crucible used will generate a large amount of SiO with the silicon solution at high temperature. SiO will react with carbon-containing components at high temperature to form a crystal rod, which is then lowered and removed from the sub-chamber of the single crystal furnace using tools.

[0003] When using the existing manual crystal rod extraction device, it is necessary to manually hinge the two upper clamping rings and lock them to clamp and lock the entire single crystal furnace rod body. The radius size of the crystal rod in different furnaces will also change, resulting in the tooling being unable to achieve the ideal use effect. Utility Model Content

The rear end of the clamp is rotatably connected to an abutment wheel to abut the end surface of the push block. Two torsion cylinders arranged up and down are connected between the fixed rod and the clamp. The torsion cylinder includes a fixed shell fixedly arranged on the outer periphery of the fixed rod, a torsion spring connected to the fixed shell and the clamp, a support plate is fixedly arranged at the rear end of the shell, the support plate is arranged in a V shape, and two left-right symmetrical support rods are fixedly arranged on the support plate. Elastic plates are sleeved on the two support rods, and the elastic plates can abut against the circumferential surface of the crystal rod.

[0006] The beneficial effects of the utility model are:

[0007] The rear ends of the left and right clamps clamp the circumference of the crystal rod, and with the support of the support plate, the crystal rods of different sizes are clamped, so that the clamping work of crystal rods of different radius models can be completed by a single person, and it is more time-saving, labor-saving, convenient and quick to take the rod. The elastic plate is in close contact with the front end of the crystal rod, which increases the friction on the crystal rod and prevents slipping, and provides better stability during the rod removal process.

[0015] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time:

[0017] Embodiment 1:

[0018] Reference Figure 1-Figure 5According to an embodiment of the utility model, a single crystal furnace crystal rod extraction tool comprises a crystal rod 10 and a shell 11. An opening 18 is provided in the shell 11. A push block 14 capable of sliding forward and backward is provided in the opening 18. The rear end of the opening 18 is provided with a left-right symmetrical opening. Guide rails 13 are fixedly connected to the upper and lower side walls of the opening 18. The guide rails 13 are arranged in a T shape. The guide rails 13 and the push block 14 are slidably matched. A pull rod 12 extending forward is fixedly provided on the push block 14. A handle is fixedly provided at the front end of the pull rod 12. Fixed rods 15 are fixedly provided at the two rear end openings of the opening 18. The two fixed rods 15 are rotatably connected to the clamping claws 1 6. The clamping jaw 16 extends backward and is provided with a fitting end capable of fitting with the circumference of the crystal rod 10. The rear end of the clamping jaw 16 is rotatably connected with an abutting wheel 17 to abut the end surface of the push block 14. Two torsion cylinders 22 arranged up and down are connected between the fixed rod 15 and the clamping jaw 16. The torsion cylinder 22 includes a fixed shell fixedly arranged on the outer periphery of the fixed rod 15, and a torsion spring connected to the fixed shell and the clamping jaw 16. A support plate 19 is fixedly arranged at the rear end of the housing 11. The support plate 19 is arranged in a V shape. Two left-right symmetrical support rods 21 are fixedly arranged on the support plate 19. The two support rods 21 are sleeved with an elastic plate 20. The elastic plate 20 can abut with the circumference of the crystal rod 10.

[0019] The single crystal furnace is opened, and the crystal rod 10 is lowered through the lifting device to take the crystal rod 10 out of the single crystal furnace. The user holds the front end part of the shell 11 and pulls the rear end handle of the pull rod 12 slidably connected in the shell 11 to move the pull rod 12 backward. The pull rod 12 simultaneously drives the fixedly connected push block 14 to move, so that the push block 14 moves backward under the guide slide of the upper and lower guide rails 13, thereby pushing the left and right ground-connected abutment wheels 17 to move away from each other through the inclined surfaces at the left and right ends of the push block 14. Under the connection of the clamping jaws 16, the clamping jaws 16 rotate with the fixed rod 15 as the rotation axis to overcome the torsion spring force at the torsion barrel 22, so that the rear end clamping end of the clamping jaws 16 abuts against the circumferential surface of the crystal rod 10, and the front end of the crystal rod 10 is tightly attached to the support plate 19. Under the squeezing of the crystal rod 10, the elastic plate 20 is deformed by pressure, such as Figure 4 As shown, the circumference of the elastic plate 20 is closely attached to the crystal rod 10 under the support of two support rods 21, thereby completing the clamping work.

[0020] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
