Description

Technical Field

[0001] The utility model relates to the technical field of equipment related to quartz crucible production, in particular to a quartz crucible clamping device. Background Art

[0002] Quartz crucibles, made of high-purity quartz sand, are increasingly popular due to their high purity, strong temperature resistance, large size and precision, excellent thermal insulation, energy conservation, and stable quality. Quartz crucibles can be primarily categorized into two types: square and round. Because the production process for quartz crucibles requires complex processing steps such as sandblasting, cutting, acid cleaning, and pure water washing, and different processes require separate workshops, quartz crucible gripping devices are often used to move the crucibles to facilitate each process.

[0003] Existing quartz crucible clamping devices generally consist of a clamping mechanism, a transmission mechanism, and a moving mechanism. The clamping mechanism, typically consisting of two clamping plates, is controlled by a transmission mechanism to clamp the quartz crucible. The moving mechanism is used to move the entire device, allowing the quartz crucible to be moved through various processing steps. This avoids contamination of the quartz glass crucible caused by manual handling, improves handling efficiency, and significantly reduces the labor intensity of operators.

[0004] However, the existing quartz crucible clamping device has the following shortcomings:

[0005] 1. The clamping plate to pick up the quartz crucible relies on the friction between the clamping plate and the side of the quartz crucible, so there is a risk of falling during the lifting process;

[0006] 2. In order to prevent the quartz crucible from detaching from the clamping plate, the clamping force may be too strong, which may easily damage the outer wall of the quartz crucible, causing unnecessary losses and waste of costs. Utility Model Content

[0007] 1. Technical Problems Solved

[0008] The technical problem to be solved by the utility model is that there is a risk of falling during clamping, and excessive clamping may cause damage to the quartz crucible, resulting in waste.

[0009] 2. Technical Solution

[0010] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: a quartz crucible clamping device, comprising a moving mechanism, wherein the moving mechanism is provided with a clamping mechanism;

[0011] The movable mechanism includes a base, a vertical plate is provided above the base, a rectangular groove is provided between the left and right side walls of the vertical plate, a bidirectional screw is provided between the front and rear inner walls of the rectangular groove, one end of the bidirectional screw extends out of the vertical plate and is connected to the motor, and the side walls of the bidirectional screw are threadedly sleeved with relative movable blocks, the left and right ends of the movable blocks extend out of the rectangular groove, and a connecting plate is provided below;

[0012] A blind hole is provided on the side of the connecting plate away from the vertical plate. The clamping mechanism includes an electric telescopic rod fixed in the blind hole. The other end of the electric telescopic rod is connected to an arc-shaped clamping plate. A rubber block is provided on the inner wall of the clamping plate. A through groove is provided in the middle of the rubber block. A pressure sensor cooperating with the motor is provided in the through groove.

[0013] As an improvement, the upper and lower side walls of the moving block are in contact with the upper and lower inner walls of the rectangular groove.

[0014] As an improvement, the left and right ends of the base and the upper end of the vertical plate are both arc-shaped structures protruding outward.

[0015] As an improvement, the thickness of the pressure sensor is smaller than the thickness of the rubber block.

[0016] As an improvement, the centers of the two clamping plates located on the same side of the vertical plate face the center of the base, and the curvature of the clamping plates is greater than the curvature of the quartz crucible.

[0017] As an improvement, support rods are rotatably provided at the corners below the base, and rollers are rotatably provided at the lower ends of the support rods.

[0018] As an improvement, the telescopic length of the electric telescopic rod is greater than half the length of the base.

[0019] 3. Beneficial Effects

[0020] The advantages of this utility model compared with the prior art are:

[0021] 1. The distance between the clamping mechanisms is controlled by a motor, and rubber blocks are provided on the inner wall of the clamping plates to increase the friction between the plates and the quartz crucible. When the clamping plates clamp the quartz crucible, the rubber blocks are squeezed. When the squeeze reaches the pressure sensor, the motor stops and controls the clamping force, ensuring a firm clamping without excessive force.

[0022] 2. The clamping mechanism can handle two quartz crucibles at the same time, making the clamping and handling efficiency higher. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] As attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, a quartz crucible clamping device includes a moving mechanism 1, a clamping mechanism 2 is provided on the moving mechanism 1, the moving mechanism 1 includes a base 3, a vertical plate 6 is provided above the base 3, a rectangular groove 7 is provided between the left and right side walls of the vertical plate 6, a bidirectional screw 8 is provided between the front and rear inner walls of the rectangular groove 7, one end of the bidirectional screw 8 extends out of the vertical plate 6 and is connected to a motor 9, and a relative moving block 10 is threadedly sleeved on the side wall of the bidirectional screw 8, the upper and lower side walls of the moving block 10 are in contact with the upper and lower inner walls of the rectangular groove 7, the left and right ends of the moving block 10 extend out of the rectangular groove 7, and the lower A connecting plate 11 is provided; a blind hole 12 is provided on the side of the connecting plate 11 away from the vertical plate 6, and the clamping mechanism 2 includes an electric telescopic rod 13 fixed in the blind hole 12, and the other end of the electric telescopic rod 13 is connected to an arc-shaped plywood 14, and a rubber block 15 is provided on the inner wall of the plywood 14, and the rubber block 15 is adhesively connected to the plywood 14. A through groove 16 is provided in the middle of the rubber block 15, and a pressure sensor 17 cooperating with the motor 9 is provided in the through groove 16. The pressure sensor 17 is adhesively connected to the inner wall of the plywood 14, and the thickness of the pressure sensor 17 is less than the thickness of the rubber block 15.

[0031] Through the above structure, after starting the motor 9, the bidirectional screw 8 rotates, and the moving block 10 is restricted by the rectangular groove 7. Under the rotation of the bidirectional screw 8, it moves synchronously toward or away from the center of the base 3, that is, the clamping mechanism 2 moves toward the center of the base 3. By controlling the electric telescopic rod 13, the clamping plate 14 can be extended to both sides of the quartz crucible, and then the motor 9 is used to move toward the quartz crucible to achieve clamping. The inner wall of the clamping plate 14 is provided with a rubber block 15, which can increase the friction between the clamping plate 14 and the quartz crucible. When the clamping plate 14 clamps the quartz crucible, the rubber block 15 is squeezed. When it is squeezed to touch the pressure sensor 17, the motor 9 stops and controls the clamping force so that the clamping is firm and the clamping force is not too large. The clamping mechanism 2 can handle two quartz crucibles at the same time, making the clamping and handling efficiency higher.

[0032] It is worth noting that the motor 9, the electric telescopic rod 13 and the pressure sensor 17 mentioned in this embodiment and their supporting power supplies and control switches can also be provided by the manufacturer. The circuits, electronic components and modules involved are all existing technologies and can be fully implemented by those skilled in the art without further explanation.

[0033] Example 2

[0034] Based on the first embodiment, please refer to the attached Figure 4

[0035] The left and right ends of the base 3 and the upper end of the vertical plate 6 are all arc-shaped structures protruding outward. Support rods 4 are rotatably provided at the corners below the base 3, and rollers 5 are rotatably provided at the lower ends of the support rods 4.

[0036] Through the above structure, the ends of the base 3 and the vertical plate 6 are rounded to avoid collision with the quartz crucible, and the base 3 is moved by the rollers 5 provided below, making it easy to move.

[0037] The centers of the two clamps 14 located on the same side of the vertical plate 6 are facing the center of the base 3, and the curvature of the clamps 14 is greater than the curvature of the quartz crucible. The curvatures of the pair of clamps 14 located on both sides of the vertical plate 6 can be set to be the same or different, which can further improve the clamping adaptability range. The telescopic length of the electric telescopic rod 13 is greater than half the length of the base 3.

[0038] With the above structure, when the clamping plate 14 clamps the quartz crucible, the middle portion can always be in contact with the quartz crucible, and the electric telescopic rod 13 can extend the clamping plate 14 to a position away from the base 3, so that the quartz crucible can be clamped more conveniently.

[0039] The specific method of use is as follows: after starting the motor 9, the bidirectional screw 8 rotates, and the moving block 10 is restricted by the rectangular slot 7 and moves synchronously toward or away from the center of the base 3 under the rotation of the bidirectional screw 8, that is, the clamping mechanism 2 moves toward the center of the base 3. By controlling the electric telescopic rod 13, the clamping plate 14 can be extended to both sides of the quartz crucible, and then the motor 9 is used to move toward the quartz crucible to achieve clamping. The inner wall of the clamping plate 14 is provided with a rubber block 15, which can increase the friction between the clamping plate 14 and the quartz crucible. When the clamping plate 14 clamps the quartz crucible, the rubber block 15 is squeezed. When it is squeezed to touch the pressure sensor 17, the motor 9 stops, controlling the clamping force so that the clamping is firm and the clamping force is not too large, and the clamping mechanism 2 can handle two quartz crucibles at the same time. Since the roller 5 is provided under the base 3, the clamping device is convenient to move and the clamping and handling efficiency is higher.
