[0037] The medium pipelines of all the floating support cylinders 31 are connected in parallel, so that the support surface can adapt to the shape of the workpiece to be supported.

[0038] In the embodiment, since the medium pipelines are connected in parallel, all the floating support cylinders 31 can simultaneously receive the same pressure signal or fluid flow, so as to realize synchronous action.

[0039] Embodiment 3

[0040] With reference to Figures 1-4 In addition to having all the technical solutions of any one of the above embodiments, the embodiments of the utility model further have the following technical solutions.

[0041] The support base 2 is internally provided with a first gas passage A, one end of the first gas passage A is in communication with the gas inlet ends of all the floating support cylinders 31, and the other end of the first gas passage A extends out of the support base 2 to form a gas inlet joint.

[0042] In the embodiment, by arranging the first gas passage A inside the support base 2, the compactness of the structure of the silicon rod floating support mechanism can be further improved, and the overall weight of the support base 2 can be reduced to a certain extent.

[0043] Embodiment 4:

[0044] With reference to Figures 1-4 The embodiments of the present application further have the following technical solutions in addition to all the technical solutions of any one of the above embodiments.

[0045] The silicon rod floating support mechanism further comprises a locking assembly, the locking assembly comprises locking bolts 4, and connecting lugs 201 are extended on both sides of the support 2, connecting grooves 202 extending along the first horizontal direction are formed on the connecting lugs 201, the locking bolts 4 are threadedly connected to the base 1 after passing through the corresponding connecting grooves 202, the locking bolts 4 are in clearance fit with the connecting grooves 202, and the heads of the locking bolts 4 can selectively press the connecting lugs 201 on the base 1.

[0046] In the present embodiment, the locking bolt 4 has a threaded portion and a head. The threaded portion is used to cooperate with the threaded hole on the base 1, and the head is used to rotate the bolt for locking or loosening operation. The connecting lug 201 is used to cooperate with the locking bolt 4. The connecting lug 201 is provided with a connecting groove 202 extending along the first horizontal direction, which provides sufficient movement space for the locking bolt 4 to switch between the locked and loosened states. The connecting groove 202 is a long hole formed on the connecting lug 201, which is designed in shape and size to accommodate the locking bolt 4 and allow the bolt to move along the first horizontal direction in the groove. This design allows the support 2 to freely slide within a certain range until it is fixed by the locking bolt 4.

[0047] When it is necessary to adjust the position of the support 2, the locking bolt 4 can be loosened to allow the connecting lug 201 to freely move in the connecting groove 202. In this way, the support 2 can be slid along the first horizontal direction to the desired position.

[0050] The locking and loosening operation of the locking assembly is relatively simple and can be completed using basic tools, improving the operation efficiency and reducing the operation difficulty.

[0051] Embodiment 5

[0052] With reference to Figures 1-4 The embodiments of the present application further have the following technical solutions in addition to all the technical solutions of any one of the above embodiments.

[0053] The floating support cylinder assembly 3 also comprises a pressure head assembly 32 fixedly connected to the top end of the floating support cylinder 31, and the top surface of all the pressure head assemblies 32 forms a support surface.

[0059] In this embodiment, the above two clearances not only ensure that the floating support cylinder 31 can be stably and reliably extended and retracted, but also realize dustproof sealing of the support base 2, because there is a certain amount of dust in the use scene of the supported silicon rod, so this structure can better realize dustproof of the floating support cylinder 31, improve the use reliability of the floating support cylinder 31, and further improve the use reliability of the silicon rod floating support mechanism.

[0060] Embodiment 7:

[0061] With reference to Figures 1-4 In addition to having all the technical solutions of any of the above embodiments, the embodiments of the utility model further have the following technical solutions:

[0062] The inner cavity of the outer cover 5 is communicated with the gas supply device to form a positive pressure cavity, the clearance between the inner wall of the sleeve part 501 and the outer wall of the top part of the floating support cylinder 31, and the clearance between the inner wall of the skirt part 320 and the outer wall of the sleeve part 501 form a gas outlet channel in mutual communication, and the gas outlet channel is in communication with the positive pressure cavity.

[0063] In this embodiment, not only rely on two gap seals in embodiment 6, the inner cavity of the outer cover 5 is connected with the gas supply device, forming a positive pressure chamber. At the same time, the gap between the sleeve part 501 and the skirt part 320 and the gap between the sleeve part 501 and the floating support cylinder 31 are connected with each other, forming an air outlet channel. The positive pressure chamber outputs air to the outside through the air outlet channel, thereby realizing pressure sealing.

[0064] Through the gap sealing and the pressure sealing of the positive pressure chamber, the double sealing effect of the silicon rod floating support mechanism is realized. This design can more effectively prevent external gas or pollutants from entering the inside of the mechanism, improve the reliability and service life of the mechanism.

This helps to reduce manufacturing costs and improve production efficiency. At the same time, this sealing structure does not rely on a sealing ring, so it almost does not increase the running resistance of the floating support cylinder 31, thereby improving the use effect of the silicon rod floating support mechanism.

[0067] Specifically, the positive pressure chambers are also connected in parallel, so that each air outlet channel maintains the same pressure, improving the uniformity and controllability of the positive pressure sealing.

[0068] The support 2 is internally provided with a second gas channel B which is connected with the positive pressure chamber at one end and extends out of the support 2 to form a sealed joint.

[0069] In this embodiment, by arranging the second gas channel B inside the support 2, the compactness of the structure of the silicon rod floating support mechanism can be further improved, and the overall weight of the support 2 can be reduced to a certain extent.

The middle floating support cylinder assembly 3 is staggered with the other two floating support cylinder assemblies 3 in the first horizontal direction forward or backward. This staggered arrangement can increase the stability and flexibility of the support.
