Description

Technical Field

[0001] The utility model belongs to the technical field of clamping a single crystal furnace, and more specifically, particularly relates to a high-stability hydraulic clamp for a single crystal furnace. Background Art

[0002] A single crystal furnace is a device that uses a graphite heater to melt polycrystalline materials such as polysilicon in an inert gas environment and grows dislocation-free single crystals using the Czochralski method.

[0003] Based on the above, the inventors have discovered the following problems: the current method for taking out a single crystal silicon ingot from a single crystal furnace is generally for an operator to wear gloves and use pliers to clamp out the ingot. However, this method of operation is not only dangerous, but the breaking strength and tensile strength of the single crystal silicon ingot are both relatively low, and the ingot shakes to a certain extent during the descent process, so the ingot is prone to breakage, and manual operation is relatively arbitrary and inefficient.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-stability single crystal furnace hydraulic clamp is provided, in order to achieve a more practical purpose. Utility Model Content

[0008] Furthermore, the clamping assembly includes a chamber opened inside the moving block, a group of half gears are provided in the chamber, the half gears are installed inside the chamber through an axle rod and a bearing seat, a rack is provided on one side of the half gear, and a clamping block is provided on one side of the rack.

[0009] Furthermore, the half gear is meshed with the rack.

[0010] Furthermore, a fixing rod is provided at the bottom of a group of the half gears, which is offset from the axis, and the fixing rod is sleeved with a T-shaped moving block, and the T-shaped moving block is connected to the vertical rod.

[0011] Further, the chamber is provided with a moving groove 1 and a moving groove 2, the moving groove 1 is provided with two groups of card blocks 1, the card blocks 1 are connected to the rack, the moving groove 2 is provided with a group of card blocks 2, the card blocks 2 are connected to the T-shaped moving block.

[0012] Furthermore, a rotating disk is provided on the top of the bidirectional threaded rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The hydraulic telescopic rod is started, causing the output end to move back, driving the sleeve rod to move. With the cooperation of the vertical rod, T-shaped moving block and half gear, the rack meshing with the half gear is brought close to achieve the clamping function. Conversely, the clamping can be released. The clamping block is a set of symmetrical semicircular arc blocks, which can better clamp the single crystal silicon and improve stability.
