Description

Technical Field

[0001] This utility model relates to the field of single crystal furnace chassis technology, and in particular to a quick-assembly and disassembly single crystal furnace chassis. Background Technology

[0002] A single crystal furnace is a specialized industrial device used to grow single crystal materials. Its core function is to precisely control conditions such as temperature, gas pressure, and melt flow to melt polycrystalline raw materials (such as silicon, germanium, and sapphire) and directionally grow single crystals with complete and continuous crystal lattices according to a specific crystal structure. These single crystals are core raw materials for high-tech products such as semiconductor chips, photovoltaic cells, and optical components. Therefore, single crystal furnaces play an irreplaceable role in fields such as electronics, new energy, and aerospace. The connection between the furnace chassis and the furnace body is mostly a flange connection, which is complex to assemble and disassemble and cannot achieve rapid assembly and disassembly.

[0003] Existing single crystal furnace chassis are often inconvenient for fixing and disassembling the single crystal furnace during installation. Some special connection structures require special customization of the single crystal furnace, such as welding connecting blocks to the bottom outer wall of the single crystal furnace, which increases the cost of using the single crystal furnace and makes the operation process more troublesome. In order to overcome the shortcomings of the existing technology, we propose a quick-disassembly single crystal furnace chassis. Utility Model Content

[0004] The main purpose of this invention is to provide a quick-assembly and disassembly single crystal furnace chassis, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A quick-assembly and disassembly single crystal furnace chassis includes a base, a movable mounting plate on top of the base, four sets of first sliding grooves symmetrically arranged around the base, and a first slider slidably connected to the middle of each of the four sets of first sliding grooves. Four sets of second sliding grooves symmetrically arranged around the movable mounting plate, and a second slider slidably connected to the middle of each of the four sets of second sliding grooves. A set of movable support arms is provided between the rear outer wall of each set of second sliders and the front outer wall of each set of first sliders. A set of fixing rods is provided at the upper end of each of the four sets of second sliders, and an arc-shaped clamping plate is fixed at the upper end of each set of fixing rods.

[0006] Preferably, each set of the first slider has a rotating connecting plate on its front outer wall and each set of the second slider has a rotating head at both ends. The rotating heads at both ends of each set of the movable support arm are rotatably connected to the rotating connecting plates on the outer walls of the first and second sliders via rotating shafts.

[0007] Preferably, a set of telescopic rods is provided between the rear end of each set of the first slider and the inner wall of the first sliding groove. The two ends of the telescopic rods are fixedly connected to the outer wall of the rear end of the first slider and the inner wall of the first sliding groove, respectively. A set of springs is nested on the outer wall of each set of telescopic rods.

[0008] Preferably, the upper end of the base has a groove in the middle, and the movable mounting plate can be fitted into the groove in the middle of the upper end of the base.

[0009] Preferably, a positioning hole is provided in the middle of one side wall of the movable mounting plate, and a positioning screw is provided in the middle of one side wall of the base. A movable hole is provided between the positioning screw and the base. The positioning screw is movably connected to the base through the movable hole. The positioning hole is a threaded hole, and the positioning screw can extend into the middle of the positioning hole and be threadedly connected to the positioning hole.

[0010] Preferably, a circular sealing ring is provided at the upper end of the movable mounting plate, and two sets of rubber pads are provided on the inner sidewall of each set of arc-shaped clamps.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the movable mounting plate, the second slider, the movable support arm, and the first slider simplify the installation and fixing of the base and the single crystal furnace, eliminating the need for additional fixing operations. Simply place the furnace body on top of the movable mounting plate, with the bottom outer wall positioned between the four sets of arc-shaped clamps. The furnace's own weight then presses the movable mounting plate downwards from above the base, causing it to move downwards. The movable support arm rotates between the base and the movable mounting plate, simultaneously pushing the first slider outwards in the middle of the first sliding groove, while the second slider moves inwards in the middle of the second sliding groove. The four sets of arc-shaped clamps then move inwards simultaneously, clamping and fixing the bottom outer wall of the single crystal furnace. The first slider also compresses the telescopic rod and spring; the spring's elasticity maintains the clamping force, preventing damage to the outer wall of the single crystal furnace. The clamping of the four sets of arc-shaped clamps prevents the single crystal furnace from swaying left and right.

[0012] In this invention, the positioning screw can move in the middle of the base, and the middle of the positioning hole it extends into connects with the movable mounting plate, thus fixing the movable mounting plate to the base. When the single crystal furnace is placed on the upper end of the movable mounting plate and clamped and fixed by four sets of arc-shaped clamping plates, the positioning screw spirals into the middle of the positioning hole, fixing the movable mounting plate to the base, thus maintaining the clamping effect and preventing easy loosening. The sealing ring can maintain the sealing of the connection between the single crystal furnace and the movable mounting plate. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figures 1-3 As shown, a quick-assembly and disassembly single crystal furnace chassis includes a base 1. A movable mounting plate 2 is disposed on the top of the base 1. The movable mounting plate 2 is used to install and connect with the bottom of the single crystal furnace. A circular sealing ring 3 is disposed on the upper end of the movable mounting plate 2 to maintain a seal between the movable mounting plate 2 and the bottom of the single crystal furnace. A groove is disposed in the middle of the upper end of the base 1, and the movable mounting plate 2 can be fitted into the groove in the middle of the upper end of the base 1. The groove provides space for the movable mounting plate 2 to move on the upper end of the base 1. A positioning hole 4 is disposed in the middle of one side wall of the movable mounting plate 2. A positioning screw 5 is disposed in the middle of one side wall of the base 1. A movable hole is disposed between the positioning screw 5 and the base 1. The positioning screw 5 is movably connected to the base 1 through the movable hole. The positioning hole 4 is a threaded hole, and the positioning screw 5 can... The positioning screw 5 extends into the middle of the positioning hole 4 and is threaded into the positioning hole 4, thus fixing the movable mounting plate 2 to the base 1. Four sets of first sliding grooves 6 are symmetrically arranged around the base 1. A set of first sliders 7 is slidably connected in the middle of each of the four sets of first sliding grooves 6. A set of telescopic rods 12 is set between the rear end of each set of first sliders 7 and the inner wall of a set of first sliding grooves 6. The two ends of the telescopic rods 12 are fixedly connected to the outer wall of the rear end of the first slider 7 and the inner wall of the first sliding groove 6, respectively. A set of springs 13 is nested in the outer wall of each set of telescopic rods 12. When the first slider 7 slides outward in the middle of the first sliding groove 6, it will compress the telescopic rods 12 and the springs 13, generating elastic force. The telescopic rods 12 and the springs 13 will provide elastic support for the first slider 7.

[0017] like Figures 1-3As shown, four sets of second sliding grooves 8 are symmetrically arranged around the movable mounting plate 2. A set of second sliders 9 is slidably connected to the center of each of the four sets of second sliding grooves 8. A set of movable support arms 15 is provided between the rear outer wall of each set of second sliders 9 and the front outer wall of each set of first sliders 7. The movable support arms 15 connect the first slider 7 and the second slider 9, and the first slider 7 supports the second slider 9 through the movable support arms 15. A rotating connecting plate 14 is provided on the front outer wall of each set of first sliders 7 and the rear outer wall of each set of second sliders 9. A rotating head 16 is provided at both ends of each set of movable support arms 15. The rotating heads 16 at both ends of each set of movable support arms 15 are respectively connected to… The rotating connecting plates 14 on the outer walls of slider 7 and slider 9 are rotatably connected by a rotating shaft. The movable support arm 15 can be rotatably connected to slider 7 and slider 9 respectively through the rotating connecting plates 14 at both ends and the rotating head 16. Each of the four groups of slider 9 is provided with a set of fixing rods 10 at the upper end. Each set of fixing rods 10 is fixed with a set of arc-shaped clamping plates 11 at the upper end. The fixing rods 10 are used to fix the arc-shaped clamping plates 11. The four sets of arc-shaped clamping plates 11 are used to clamp and fix the bottom of the single crystal furnace around its perimeter. Each set of arc-shaped clamping plates 11 is provided with two sets of rubber pads 17 on the inner side wall. The rubber pads 17 are used to protect the outer wall of the single crystal furnace and increase friction.

[0018] It should be noted that this utility model is a quick-assembly and disassembly single crystal furnace chassis. In use, the single crystal furnace is placed on top of the movable mounting plate 2, with its bottom in contact with the sealing ring 3. Simultaneously, due to the weight of the single crystal furnace itself, a downward pressure is applied to the movable mounting plate 2, causing it to move downwards at the top of the base 1. The surrounding movable support arms 15 then rotate between the second slider 9 and the first slider 7, respectively. This pushes the second slider 9 inwards in the middle of the second sliding groove 8, and pushes the first slider 7 outwards in the middle of the first sliding groove 6. The four sets of second sliders 9 drive the four sets of arc-shaped clamping plates 11 to move inwards, contacting the outer walls of the bottom of the single crystal furnace, clamping and fixing the lower end of the furnace. The first slider 7 will... The telescopic rod 12 and spring 13 are compressed, providing elastic support to the first slider 7 and the movable support arm 15. This ensures that the clamping force of the arc-shaped clamping plate 11 is elastic and will not exert excessive pressure on the outer wall of the single crystal furnace, causing deformation. After the movable mounting plate 2 is pressed into the groove in the middle of the base 1, the positioning screw 5 on the side wall of the rotating base 1 extends into the positioning hole 4 in the middle of the side wall of the movable mounting plate 2, so that the positioning screw 5 is threadedly connected to the positioning hole 4, thus fixing the movable mounting plate 2 to the base 1. This completes the installation and fixing of the chassis and the single crystal furnace. When disassembling, the positioning screw 5 is removed from the side wall of the base 1, and the single crystal furnace is lifted upwards to disassemble the chassis. The operation is simple and convenient.
