Abstract
Description
Technical Field
[0001] This utility model relates to the field of alumina crucible technology, and specifically to a fixing device for processing alumina crucibles. Background Technology
[0002] In the processing and production of alumina crucibles, the fixing device is a key piece of equipment to ensure processing accuracy and stability. Due to different application scenarios, alumina crucibles vary significantly in size and specifications, ranging from micro crucibles used in laboratories to large crucibles used in industrial production, with a wide range of diameters and heights.
[0003] The aforementioned problems are as follows: Existing fixing devices are difficult to achieve effective fixation. For small crucibles, traditional clamps are too large to be accurately positioned, which easily leads to problems such as insecure clamping and shaking during processing, resulting in a decrease in processing accuracy. For large crucibles, the load-bearing capacity and structural size of the fixing device are limited, making it impossible to fix them securely. Forced fixing may cause uneven stress on the crucible, or even produce quality defects such as cracks and breakage. In addition, frequent replacement of fixing devices adapted to different crucibles increases operation time and labor costs. Therefore, a fixing device for alumina crucible processing is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a fixing device for processing alumina crucibles, so as to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A fixing device for processing alumina crucibles includes a processing table and alumina crucibles. The processing table has a fixing component inside for simultaneously clamping alumina crucibles of different sizes. The fixing component includes a mounting block, one side of which is fixedly connected to one side of the processing table. A motor is fixedly mounted on the top of the mounting block. A forward and reverse screw is rotatably connected inside the processing table. A movable frame is threaded to the outer wall of the forward and reverse screw. A clamping plate is fixedly connected to the outer wall of the movable frame. The inside of the clamping plate contacts the outer walls of multiple alumina crucibles. An auxiliary component is provided on the top of the clamping plate for secondary clamping of excessively large alumina crucibles.
[0007] The above technical solution involves the coordinated operation of a forward and reverse screw, a motor, a clamping plate, and a mounting block. In the fixing assembly, the motor drives the forward and reverse screw to rotate, and the moving frame moves the clamping plate through threaded transmission. This allows for the simultaneous clamping and fixing of alumina crucibles of different sizes, eliminating the need for frequent fixture changes for crucibles of different specifications, improving processing efficiency, and adapting to diverse production needs.
[0008] A further improvement of this utility model is that: a sliding groove is provided inside the processing table, and the inside of the sliding groove is slidably connected to the outer wall of the moving frame.
[0009] The above technical solution involves the cooperation of a sliding groove and a moving frame. The sliding groove in the processing table cooperates with the moving frame to provide stable guidance for the movement of the moving frame. When adjusting the position of the clamping plate, the moving frame slides along the sliding groove, which effectively prevents the moving frame from shifting or shaking during the movement, ensuring that the clamping plate runs smoothly, accurately positions and clamps the alumina crucible, and improves the accuracy of the fixing operation.
[0010] A further improvement of the present invention is that the auxiliary component includes a connecting block, the outer wall of the connecting block is fixedly connected to one side of the clamping plate, and a screw is threadedly connected to the inside of the connecting block.
[0011] The above technical solution involves the cooperation of a clamping plate and a screw. The auxiliary component is connected to the connecting block by a screw thread. Rotating the screw can adjust the position of the positioning ring. For alumina crucibles that are too large, the positioning ring can be brought closer to the outer wall of the crucible by adjusting the screw, thereby achieving secondary clamping, enhancing the fixing effect on large crucibles, and expanding the applicability of the device.
[0012] A further improvement of this utility model is that a positioning ring is fixedly connected to the outer wall of the screw, and the inside of the positioning ring is in contact with the outer wall of the alumina crucible.
[0013] The above technical solution involves the cooperation between a positioning ring and an alumina crucible. The positioning ring contacts the outer wall of the alumina crucible and can fit tightly according to the crucible's outline. By adjusting the screw, the positioning ring can be made to fully contact the crucible, increasing friction and preventing the crucible from shifting or rotating during processing. This further improves the stability of the fixing device for large-sized crucibles.
[0014] A further improvement of the present invention is that: a movable groove is provided inside the clamping plate, a movable block is slidably connected inside the movable groove, and the outer wall of the movable block is fixedly connected to the outer wall of the positioning ring.
[0015] The above technical solution involves the cooperation of a moving groove, a moving block, and a positioning ring. The moving groove and the moving block in the clamping plate provide guidance for the movement of the positioning ring. When the screw is rotated to adjust the position of the positioning ring, the moving block slides along the moving groove to ensure that the positioning ring moves smoothly and can accurately reach the predetermined position, thereby achieving precise clamping and fixing of the alumina crucible.
[0016] A further improvement of this utility model is that a torsion block is fixedly connected to one end of the screw.
[0017] By adopting the above technical solution, the screw and the torsion block are designed to work together. The torsion block at one end of the screw provides the operator with a point of force application, making it easy to manually rotate the screw without the need for additional tools. The operator can quickly and conveniently adjust the position of the positioning ring to achieve secondary clamping or loosening of the alumina crucible, simplifying the operation process and improving the efficiency of processing preparation.
[0018] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared with the prior art is: it eliminates the need to frequently change fixtures for crucibles of different specifications, improves processing efficiency, and adapts to diversified production needs.
[0019] 1. This utility model provides a fixing device for processing alumina crucibles. By setting up a forward and reverse screw, a motor, a clamping plate and a mounting block in cooperation, the motor drives the forward and reverse screw to rotate in the fixing assembly. The moving frame drives the clamping plate to move through the threaded transmission. It can clamp and fix alumina crucibles of different sizes at the same time, without the need to frequently change the clamps for crucibles of different specifications, thereby improving processing efficiency and adapting to diversified production needs.
[0020] 2. This utility model provides a fixing device for processing alumina crucibles. By setting up a clamping plate and a screw to cooperate with each other, the auxiliary components are connected to the connecting block by the screw. Rotating the screw can adjust the position of the positioning ring. For alumina crucibles that are too large, the positioning ring can be brought closer to the outer wall of the crucible by adjusting the screw, so as to achieve secondary clamping, enhance the fixing effect on large crucibles, and expand the applicability of the device.

[0026] The present invention will be further described in detail below with reference to embodiments:
[0027] Example 1
[0028] like Figure 1-4 As shown, this utility model provides a fixing device for processing alumina crucibles, including a processing table 1 and an alumina crucible 2. The processing table 1 is provided with a fixing component for simultaneously clamping alumina crucibles 2 of different sizes. The fixing component includes a mounting block 3, one side of which is fixedly connected to one side of the processing table 1. A motor 4 is fixedly installed on the top of the mounting block 3. A forward and reverse screw 5 is rotatably connected inside the processing table 1. A movable frame 6 is threadedly connected to the outer wall of the forward and reverse screw 5. A clamping plate 7 is fixedly connected to the outer wall of the movable frame 6. The inside of the clamping plate 7 contacts the outer walls of multiple alumina crucibles 2. An auxiliary component is provided on the top of the clamping plate 7 for secondary clamping of excessively large alumina crucibles 2. A sliding groove 8 is provided inside the processing table 1, and the inside of the sliding groove 8 is slidably connected to the outer wall of the movable frame 6.
[0029] In this embodiment, by setting up the mutual cooperation of the forward and reverse screw 5, motor 4, clamping plate 7 and mounting block 3, in the fixing assembly, the motor 4 drives the forward and reverse screw 5 to rotate, and the moving frame 6 drives the clamping plate 7 to move through the threaded transmission. It can clamp and fix alumina crucibles 2 of different sizes at the same time, without the need to frequently change the clamps for crucibles of different specifications, thereby improving processing efficiency and adapting to diversified production needs. By setting up the mutual cooperation of the slide groove 8 and the moving frame 6, the slide groove 8 in the processing table 1 cooperates with the moving frame 6 to provide stable guidance for the movement of the moving frame 6. When adjusting the position of the clamping plate 7, the moving frame 6 slides along the slide groove 8, which effectively prevents the moving frame 6 from deviating or shaking during the movement, ensuring that the clamping plate 7 runs smoothly, accurately positions and clamps the alumina crucible 2, and improves the accuracy of the fixing operation.
[0030] Example 2
[0031] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the auxiliary component includes a connecting block 9, the outer wall of the connecting block 9 is fixedly connected to one side of the clamping plate 7, the connecting block 9 is internally threaded with a screw 10, the outer wall of the screw 10 is fixedly connected with a positioning ring 11, the inside of the positioning ring 11 is in contact with the outer wall of the alumina crucible 2, the clamping plate 7 has a moving groove 12 inside, the moving groove 12 is slidably connected with a moving block 13, the outer wall of the moving block 13 is fixedly connected to the outer wall of the positioning ring 11, and one end of the screw 10 is fixedly connected with a torsion block 14.
[0032] In this embodiment, by setting the clamping plate 7 and the screw 10 to cooperate with each other, the auxiliary component is threadedly connected to the connecting block 9 through the screw 10. Rotating the screw 10 can adjust the position of the positioning ring 11. For alumina crucibles 2 that are too large, the positioning ring 11 can be brought closer to the outer wall of the crucible by adjusting the screw 10, thereby achieving secondary clamping, enhancing the fixing effect on large-sized crucibles, and expanding the applicability of the device. By setting the positioning ring 11 and the alumina crucible 2 to cooperate with each other, the positioning ring 11 contacts the outer wall of the alumina crucible 2 and can fit tightly according to the shape contour of the crucible. By adjusting the screw 10 to make the positioning ring 11 fully contact the crucible, the friction is increased, preventing the crucible from shifting or rotating during processing, and further improving the fixing stability of the fixing device for large-sized crucibles. The moving groove 12, the moving block 13, and the positioning ring 11 cooperate with each other. The moving groove 12 and the moving block 13 in the clamping plate 7 provide guidance for the movement of the positioning ring 11. When the screw 10 is rotated to adjust the position of the positioning ring 11, the moving block 13 slides along the moving groove 12 to ensure that the positioning ring 11 moves smoothly and can accurately reach the predetermined position, so as to achieve precise clamping and fixing of the alumina crucible 2. By setting the screw 10 and the torsion block 14 to cooperate with each other, the torsion block 14 at one end of the screw 10 provides the operator with a force point, which makes it convenient to manually rotate the screw 10 without the need for additional tools. The operator can quickly and conveniently adjust the position of the positioning ring 11 to achieve secondary clamping or loosening of the alumina crucible 2, simplifying the operation process and improving the efficiency of processing preparation.
[0033] The working principle of the fixing device for processing alumina crucible 2 will be explained in detail below.
[0034] like Figure 1-4 As shown, when it is necessary to fix the alumina crucible 2, the motor 4 on the top of the mounting block 3 is started. The motor 4 drives the forward and reverse screw 5 inside the processing table 1 to rotate. Due to the special thread structure of the forward and reverse screw 5, its rotation will cause the moving frame 6 connected to the outer wall thread to move in opposite directions or away from each other along the sliding groove 8 inside the processing table 1. The moving frame 6 drives the clamping plate 7 to move synchronously until the clamping plate 7 is in close contact with the outer wall of the alumina crucible 2, thus completing the initial clamping and fixing of the crucible. The spacing of the clamping plate 7 can be automatically adjusted according to the crucible size to achieve stable clamping of crucibles of different sizes at the same time.
[0035] For alumina crucible 2 that is too large, relying solely on the basic fixing components may not provide sufficient stability. In this case, the operator rotates the torsion block 14 at one end of the screw 10, causing the screw 10 to perform threaded transmission within the connecting block 9. The screw 10 drives the positioning ring 11 to move, and the moving block 13 on the outer wall of the positioning ring 11 slides along the moving groove 12 inside the clamping plate 7, ensuring that the positioning ring 11 smoothly approaches the outer wall of the crucible. When the positioning ring 11 is tightly fitted with the outer wall of the crucible, a secondary reinforcement of the crucible is achieved, enhancing the fixing effect on large-sized crucibles.
[0036] Throughout the fixing process, the basic fixing components and auxiliary components work together. The basic fixing components drive the forward and reverse lead screw 5 via motor 4 to achieve rapid initial fixing of crucibles of different sizes. The auxiliary components provide secondary reinforcement for crucibles of special sizes to ensure that all crucibles remain stable during processing. The cooperation between the sliding groove 8 and the moving frame 6, and the moving slot 12 and the moving block 13 inside the processing table 1, provides stable guidance for the movement of the clamping plate 7 and the positioning ring 11, ensuring the accuracy and reliability of the fixing operation and fully meeting the fixing requirements of the alumina crucible 2 during processing.
[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
