Description

Technical Field

[0001] This utility model relates to the field of Faraday crystal cutting technology, and in particular to a precision orientation device for Faraday crystal cutting. Background Technology

[0002] As a key functional material in the field of optoelectronics, the cutting precision of Faraday crystals directly affects the performance stability of optical devices. Their cutting is generally carried out by diamond wire cutting. In the crystal cutting process, the orientation device is a key structure used to realize the movement of the Faraday crystal after it is positioned.

[0003] Traditional Faraday crystal orientation devices typically employ a simple threaded lifting structure, using mechanical rotation to adjust the crystal height and complete the cutting. However, this design has significant technical drawbacks: on the one hand, the threaded lifting section lacks an effective sealing structure, allowing dust to easily enter the thread gap during use, accelerating the wear and corrosion of mechanical parts, and consequently causing problems such as lifting jamming and positioning deviation, seriously affecting cutting accuracy and equipment lifespan. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a precision orientation device for Faraday crystal cutting. This orientation device improves upon the limitations of existing orientation devices that only perform a single lifting function by adding actual sealing performance, thus ensuring the service life of the threaded lifting section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precision orientation device for Faraday crystal cutting includes a base plate, with multiple vertical rods fixedly connected to the upper end of the base plate, and a top plate fixedly connected to the upper ends of the multiple vertical rods; a lifting mechanism including multiple connecting rods fixedly connected to the upper end of the base plate, a lifting plate disposed above the base plate, a horizontal plate fixedly connected to the upper ends of the multiple connecting rods, a drive motor mounted on the lower end of the horizontal plate, the output shaft of the drive motor passing through the horizontal plate and fixedly connected to a threaded rod, an internal threaded cylinder fixedly connected to the lower end of the lifting plate, and the upper end of the threaded rod extending into the internal threaded cylinder and threadedly connected to the inner wall of the internal threaded cylinder.

[0007] Preferably, all of the vertical rods pass through the lifting plate and are slidably connected to the lifting plate.

[0008] Preferably, the drive motor is a servo motor that can change the direction of rotation.

[0009] Preferably, the upper end of the lifting plate is provided with a conical groove, the inner bottom of the conical groove is fixedly connected to a connecting seat, and the upper end of the connecting seat is provided with multiple threaded mounting holes.

[0010] Preferably, a sleeve is fixedly connected to the upper end of the horizontal plate, and an annular sealing ring is fixedly connected to the inner side of the upper part of the sleeve, with the inner side of the annular sealing ring contacting the outer side of the internally threaded cylinder.

[0011] Preferably, a drainage channel is provided at the bottom of the conical groove, and a rubber sealing plug is installed on the right side of the drainage channel. The right side of the rubber sealing plug is connected to the right side of the lifting plate by a connecting rope.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By controlling the drive motor to rotate in both directions in a fixed quantity via PLC, the threaded rod drives the internal threaded cylinder and the lifting plate to move up and down precisely, thereby moving the Faraday crystal precisely closer to or further away from the diamond wire cutting assembly, achieving high-precision cutting of the Faraday crystal and improving cutting quality and yield.

[0014] 2. The liquid waste generated during cutting is concentrated in the conical groove. The liquid can be drained by pulling out the rubber sealing plug on the right side of the drainage channel. The operation is simple. After drainage, the liquid is resealed to prevent leakage. The rubber sealing plug is connected to the lifting plate by a connecting rope to avoid loss and ensure the convenience and integrity of the device.

[0015] 3. It is equipped with a sleeve and an annular sealing ring. The inner side of the annular sealing ring contacts the outer side of the internal threaded cylinder. This method can ensure that the threaded rod is always in a sealed environment and improve its service life. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-3 A precision orientation device for Faraday crystal cutting includes a base plate 1, with multiple vertical rods 2 fixedly connected to the upper end of the base plate 1, and a top plate 3 fixedly connected to the upper ends of the multiple vertical rods 2. The lower end of the top plate 3 is used to install a diamond wire cutting assembly. Subsequently, when the device is activated, cutting can be achieved by cooperating with the orientation of the lifting mechanism.

[0022] The system also includes a lifting mechanism, which includes multiple connecting rods 7 fixedly connected to the upper end of the base plate 1. A lifting plate 4 is provided above the base plate 1. The upper ends of the multiple connecting rods 7 are fixedly connected to a horizontal plate 8. A drive motor 9 is installed at the lower end of the horizontal plate 8. The output shaft of the drive motor 9 passes through the horizontal plate 8 and is fixedly connected to a threaded rod 12. An internal threaded cylinder 11 is fixedly connected to the lower end of the lifting plate 4. The upper end of the threaded rod 12 extends into the internal threaded cylinder 11 and is threadedly connected to the inner wall of the internal threaded cylinder 11. Multiple vertical rods 2 pass through the lifting plate 4 and are slidably connected to the lifting plate 4.

[0023] Among them, the upper end of the horizontal plate 8 is fixedly connected to the sleeve 10, and the inner side of the upper part of the sleeve 10 is fixedly connected to the annular sealing ring. The inner side of the annular sealing ring contacts the outer side of the internal threaded cylinder 11. By adopting this method, the threaded rod 12 can always be in a sealed environment, thereby improving its service life.

[0024] The upper end of the lifting plate 4 is provided with a conical groove 5. A connecting seat 6 is fixedly connected to the inner bottom of the conical groove 5. The upper end of the connecting seat 6 is provided with multiple threaded mounting holes. A limiting component can be installed through the threaded mounting holes to facilitate limiting during cutting. A drain channel 13 is provided at the inner bottom of the conical groove 5. A rubber sealing plug 14 is installed on the right side of the drain channel 13. The right side of the rubber sealing plug 14 is connected to the right side of the lifting plate 4 through a connecting rope 15. The connecting rope 15 can prevent the rubber sealing plug 14 from being lost.

[0025] Among them, the drive motor 9 is a servo motor that can change the direction of rotation. Furthermore, the drive motor 9 can be controlled by PLC to perform forward and reverse quantitative rotation to achieve precision cutting.

[0026] In this invention, the drive motor 9 is started, and the PLC controls the drive motor 9 to rotate in both directions in a quantitative manner. When the drive motor 9 rotates forward, its output shaft drives the threaded rod 12 to rotate in the forward direction. Since the threaded rod 12 is threadedly connected to the internal threaded cylinder 11, and the lifting plate 4 cannot rotate under the guidance of the vertical rod 2, the internal threaded cylinder 11 will drive the lifting plate 4 to move upward, thereby driving the Faraday crystal fixed on the lifting plate 4 to move upward and approach the diamond wire cutting assembly installed at the lower end of the top plate 3. When the Faraday crystal contacts the diamond wire cutting assembly, cutting is achieved in conjunction with the directional rise of the lifting plate 4 when the diamond wire cutting assembly is started. When it is necessary to adjust the cutting position or perform a reverse cutting operation, the PLC controls the drive motor 9 to rotate in the reverse direction, the threaded rod 12 to rotate in the reverse direction, and the internal threaded cylinder 11 drives the lifting plate 4 to move downward, so that the Faraday crystal is away from the diamond wire cutting assembly, thereby achieving precision cutting.

[0027] During the cutting process, if liquid waste is generated, it will accumulate at the conical groove 5. When drainage is required, the rubber sealing plug 14 installed on the right side of the drainage channel 13 is pulled out, and the liquid waste flows out from the drainage channel 13. After drainage is completed, the rubber sealing plug 14 is reinserted into the right side of the drainage channel 13 to seal it. The right side of the rubber sealing plug 14 is connected to the right side of the lifting plate 4 via a connecting rope 15, which can prevent the rubber sealing plug 14 from being lost during the drainage operation.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
