Description

Technical Field

[0001] This utility model belongs to the field of single crystal furnace sub-chamber assembly technology, specifically a support tooling for assembling a single crystal furnace sub-chamber. Background Technology

[0002] The auxiliary chamber serves as a buffer zone between the main furnace chamber and external equipment, providing a dedicated channel for seed crystal introduction and new crystal extraction. Pressure and temperature are controlled in zones via isolation valves to ensure the independence of the crystal growth environment. The auxiliary chamber is typically supported during assembly using a connected auxiliary chamber support fixture.

[0003] Chinese patent CN222958516U discloses a support fixture for assembling a sub-chamber of a single crystal furnace. The fixture includes a support frame, vertical square tubes, and rollers. A vertical square tube is connected to the center of each of the two sides of the top of the support frame. A horizontal square tube connects to the upper middle part of the two vertical square tubes. Support plates connected to the vertical tubes are located on the front and rear sides of both ends of the horizontal square tube. Rollers are rotatably connected between two support plates on one side via a rotating shaft. A sealing plate is provided at the top of the vertical tube. Reinforcing ribs are provided between the top of the support frame and the vertical tube, and between the bottom of the horizontal square tube and the vertical tube. Through its reasonable structural design, the fixture effectively supports the sub-chamber of the single crystal furnace and keeps it away from the bottom surface, facilitating assembly operations, improving assembly efficiency, and allowing for the auxiliary rotation or fixation of the sub-chamber as needed, enabling assembly operations from different angles and improving usability.

[0004] In the current technology, because the diameters of the single crystal furnace sub-chambers are different, while the distance between the rollers is fixed, when a larger single crystal furnace sub-chamber is placed, it may be unstable and easily fall off during rotation; when a smaller single crystal furnace sub-chamber is placed, it may be impossible to place it due to its small diameter, resulting in limited applicability of the aforementioned support fixture.

[0005] Therefore, a support fixture for assembling the sub-chamber of a single crystal furnace is proposed to address the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] Please see Figure 1 - Figure 6 This utility model provides a support fixture for assembling a sub-chamber of a single crystal furnace, including a base plate 1. An adjustable lifting frame 21 is provided above the base plate 1. An adjustment mechanism is provided above the lifting frame 21. The adjustment mechanism includes two fixed plates 3 fixed to the top of both ends of the lifting frame 21. A bidirectional lead screw 35 is rotatably connected between the two fixed plates 3 on the same side through a bearing. Two moving blocks 31 are threadedly connected to each bidirectional lead screw 35. Rollers 32 are rotatably connected to the top of each moving block 31. A linkage mechanism is provided between the two bidirectional lead screws 35 for driving the two bidirectional lead screws 35 to rotate synchronously. A motor 34 is fixed to the side wall of one of the fixed plates 3, and the output shaft of the motor 34 is fixed to one end of the bidirectional lead screw 35.

[0021] During operation, to address the inconvenience of adjusting the dimensions between rollers 32, it is necessary to adjust the distance between adjacent rollers 32. This is achieved by activating motor 34, which drives bidirectional lead screw 35 to rotate via its output shaft. The bidirectional lead screw 35 then drives moving block 31 in the opposite direction, which in turn drives roller 32 in the opposite direction until the desired position is reached. Furthermore, the two bidirectional lead screws 35 are connected by a linkage mechanism, which in turn drives another bidirectional lead screw 35 to rotate, thus achieving synchronous rotation of the four rollers 32. This solves the problem of inconvenience in adjusting the dimensions between rollers 32 and facilitates improved stability of the single crystal furnace sub-chamber.

[0022] Furthermore, such as Figure 2 and Figure 6 As shown, the linkage mechanism includes sprockets 37 fixed to one end of two bidirectional lead screws 35, and a chain 33 is sleeved between the two sprockets 37. A tension sensor is integrated on the chain 33.

[0023] During operation, the motor 34 drives the connected bidirectional lead screw 35 to rotate, which in turn drives the connected sprocket 37 to rotate the chain 33. The chain 33 then drives another sprocket 37 to rotate, which in turn drives the connected bidirectional lead screw 35 to rotate, thus achieving synchronous rotation of the two bidirectional lead screws 35.

[0024] Furthermore, such as Figure 6 As shown, two guide rods 36 are fixedly connected between the two fixed plates 3 on the same side, and the moving blocks 31 are slidably connected to the two guide rods 36.

[0025] During operation, the movable block 31 slides on the two guide rods 36, which limit the movable block 31 to slide in the horizontal direction.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, fixed frames 2 are slidably connected to the bottom of both ends of the lifting frame 21, and rotating frames 11 are fixedly connected to the bottom of the two fixed frames 2. A cylinder 22 is fixedly connected to the top of the rotating frame 11, and the output end of the cylinder 22 is fixedly connected to the bottom of the lifting frame 21.

[0027] When the height of the lifting frame 21 needs to be adjusted to meet the assembly requirements during operation, the cylinder 22 needs to be activated. The output end of the cylinder 22 drives the lifting frame 21 to move. During the movement, both ends of the lifting frame 21 slide within the fixed frame 2. The fixed frame 2 limits the lifting frame 21 to move stably in the vertical direction.

[0028] Furthermore, such as Figure 5 As shown, connecting blocks 23 are symmetrically fixed at both ends of the bottom of the lifting frame 21. Connecting rods 27 are rotatably connected to each connecting block 23 via pins. Sliding blocks 26 are rotatably connected to the bottom ends of each connecting rod 27 via pins. A horizontal plate 24 is fixed between the fixed frames 2. Slide rails 25 are fixed at both ends of the bottom of the horizontal plate 24. The sliding blocks 26 slide within the slide rails 25.

[0029] During operation, as the lifting frame 21 moves, it drives one end of the connecting block 23 to move. As the connecting block 23 moves, it drives one end of the connecting rod 27 to move upward through the pin. The other end of the connecting rod 27 drives the sliding block 26 to slide through the pin. The sliding block 26 slides on the slide rail 25. Finally, the connecting rod 27 and the lifting frame 21 form a triangle, which provides stability for the lifting frame 21.

[0030] Furthermore, such as Figure 4 As shown, the top of the base plate 1 is rotatably connected to a turntable 110 via a bearing, and the rotating frame 11 is fixedly connected to the top of the turntable 110.

[0031] During operation, the turntable 110 facilitates the rotation of the rotating frame 11, lifting mechanism, adjustment mechanism and single crystal furnace sub-chamber, thereby facilitating the assembly of the single crystal furnace sub-chamber at different angles.

[0032] Furthermore, such as Figure 2 and Figure 3 As shown, a fixing tube 13 is fixedly connected to each of the four corners of the bottom of the base plate 1; a support block 14 is slidably connected to the bottom end of each fixing tube 13; a threaded rod 15 is rotatably connected to the top inner wall of each fixing tube 13 through a bearing; a first bevel gear 16 is fixedly connected to the top of each threaded rod 15; a rotating rod 18 is rotatably connected to each fixing tube 13; a second bevel gear 17 is fixedly connected to one end of each rotating rod 18; the second bevel gear 17 meshes with the first bevel gear 16; and a rotating block 19 is fixedly connected to the other end of each rotating rod 18.

[0033] During operation, the ground may not be flat, causing the support fixture to wobble during assembly. The height of the support block 14 needs to be adjusted to ensure the stability of the support fixture. When adjustment is needed, the rotating block 19 is rotated, which drives the rotating rod 18 to rotate. The rotating rod 18 drives the second bevel gear 17 to rotate, which drives the first bevel gear 16 to rotate. The first bevel gear 16 drives the threaded rod 15 to rotate, which drives the support block 14 to move until it reaches the appropriate height.

[0034] Furthermore, such as Figure 2 As shown, each of the four corners of the bottom of the base plate 1 is equipped with a movable wheel 12, and a brake pad is provided on one side of the movable wheel 12.

[0035] During operation, the moving wheels 12 facilitate the movement of the support fixture to a suitable position, and the brake pads facilitate the fixing of the support fixture in the set position to prevent shaking during assembly.

[0036] Working principle: To adjust the distance between two adjacent rollers 32, the motor 34 is turned on. The output shaft of the motor 34 drives the bidirectional lead screw 35 to rotate. The bidirectional lead screw 35 drives the moving block 31 to move in the opposite direction. The moving block 31 drives the rollers 32 to move in the opposite direction until the appropriate position is reached. The bidirectional lead screw 35 drives the connected sprocket 37 to rotate the chain 33. The chain 33 drives another sprocket 37 to rotate, which in turn drives the connected bidirectional lead screw 35 to rotate. This achieves synchronous rotation of the four rollers 32, thus solving the problem of inconvenient adjustment of the size between the rollers 32 and improving the stability of the single crystal furnace sub-chamber.

[0037] When the height of the lifting frame 21 needs to be adjusted to meet assembly requirements, the cylinder 22 needs to be activated. The output end of the cylinder 22 drives the lifting frame 21 to move. During the movement, both ends of the lifting frame 21 slide within the fixed frame 2. The fixed frame 2 limits the lifting frame 21 to move stably in the vertical direction. During the movement, the lifting frame 21 drives one end of the connecting block 23 to move. During the movement, the connecting block 23 drives one end of the connecting rod 27 to move upward through the pin. The other end of the connecting rod 27 drives the sliding block 26 to slide through the pin. The sliding block 26 slides on the slide rail 25. Finally, the connecting rod 27 and the lifting frame 21 form a triangle, providing stability for the lifting frame 21.

[0038] When the support fixture is in operation, the ground may not be flat, causing shaking during assembly. It is necessary to adjust the height of the support block 14 to ensure the stability of the support fixture. When adjustment is needed, the rotating block 19 is rotated, which drives the rotating rod 18 to rotate. The rotating rod 18 drives the second bevel gear 17 to rotate, which drives the first bevel gear 16 to rotate. The first bevel gear 16 drives the threaded rod 15 to rotate, which drives the support block 14 to move until it reaches the appropriate height.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
