Description

Technical Field

[0001] This utility model relates to the field of sapphire crystal processing technology, specifically a jig for sapphire crystal processing. Background Technology

[0002] Sapphire crystals are grown by melting and recrystallizing high-purity alumina at high temperatures. After the crystals are processed into crystal rods, which are the raw materials required for wafer processing, the crystal rods are usually subjected to deep processing after the surface of the crystal rods is rounded. Therefore, the reliability and stability of the crystal rod positioning fixtures are very important.

[0003] A search revealed a sapphire crystal processing fixture (CN220593657U), comprising a clamping base with a clamping groove on its upper clamping surface and a guide slide engaged above the support of the clamping base. A pressing clamping assembly is disposed above the support of the guide slide. The pressing clamping assembly includes a drive housing mounted above the guide slide. Lifting screws are installed at both ends inside the cavity of the drive housing, and a drive motor is installed at the middle position on one side of the drive housing. The drive motor is connected to the two sets of lifting screws via a synchronous belt. Two sets of lifting slides are symmetrically mounted on the shaft ends of the two sets of lifting screws, and an arm support plate is installed between the two sets of lifting slides. Multiple pressure head mechanisms penetrating the guide slide are arranged and installed below the arm support plate.

[0004] The technical solution has at least the following drawbacks: While this invention can facilitate the processing of sapphire crystals by limiting their movement, and the position of the limiting component can be adjusted according to the length of the sapphire crystal, the need for bolts to be used for knob positioning after each adjustment is too cumbersome. Furthermore, after clamping and limiting the processing, it is inconvenient to remove the sapphire crystal, necessitating improvement. Therefore, we propose a sapphire crystal processing fixture. Utility Model Content

[0005] The purpose of this invention is to provide a jig for processing sapphire crystals, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sapphire crystal processing fixture, comprising a fixture table, a positioning groove formed in the middle of the upper end of the fixture table, a fixing frame provided at the upper end of the fixture table, a hydraulic cylinder fixedly mounted at the upper end of the fixing frame, sliding grooves formed on both sides of the fixture table, a slider fixedly mounted on the inner side of the lower end of the fixing frame, a first rack provided on the outer side of the fixing frame, an electric cylinder fixedly mounted on both sides of the lower end of the fixture table, a connecting rod mounted on the output end of the electric cylinder, a top rod fixedly mounted in the middle of the upper end of the connecting rod, and a second rack welded to both sides of the connecting rod.

[0007] By adopting the above technical solution, the connecting rod can drive the second rack to move and mesh with the first rack, thereby limiting the position of the fixed frame after sliding. This eliminates the trouble of workers using bolts to limit the position of the fixed frame after each adjustment. After the sapphire crystal is processed, the connecting rod can be driven to move and drive the top rod to move upward. The top rod lifts the sapphire crystal in the positioning groove, making it easier for workers to remove the sapphire crystal.

[0008] Optionally, the upper end of the top rod can move through the lower part of the positioning groove, and the lower end of the connecting rod is in contact with the lower end of the fixture table.

[0009] By adopting the above technical solution, it is easy to ensure the lifting effect of the push rod on the sapphire crystal.

[0010] Optionally, the size of the slider is adapted to the size of the groove, and the slider and the groove are slidably connected.

[0011] By adopting the above technical solution, the sliding of the slider and the sliding groove are combined to ensure the stability of the fixed frame sliding, thereby facilitating the positioning of the sapphire crystal.

[0012] Optionally, a rubber plate is installed at the output end of the hydraulic cylinder, and the rubber plate is positioned directly above the positioning groove.

[0013] By adopting the above technical solution, it is convenient to compress and confine the sapphire crystal using a rubber sheet.

[0014] Optionally, the length of the first rack is less than the length of the second rack.

[0015] By adopting the above technical solution, it is convenient to use the first rack and the second rack to cooperate, thereby limiting the position of the fixing frame.

[0016] Optionally, the first rack is disposed below the second rack, and the first rack meshes with the second rack.

[0017] By adopting the above technical solution, it is easy to ensure the limiting effect of the fixing frame, thus eliminating the trouble of bolt positioning.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application, through the setting of a clamping table, hydraulic cylinder, rubber plate, fixed frame, first rack, electric cylinder, push rod and second rack, can make the connecting rod drive the second rack to move and make the second rack mesh with the first rack, thereby limiting the position of the fixed frame after sliding, saving the workers the trouble of using bolts to limit the fixed frame after each adjustment. After the sapphire crystal is processed, it can drive the connecting rod to move and make the connecting rod drive the push rod to move upward. The push rod lifts the sapphire crystal in the positioning groove, thereby making it convenient for workers to remove the sapphire crystal. Attached Figure Description

[0024] Please see Figure 1-2 This utility model provides a technical solution: a sapphire crystal processing fixture, including a fixture table 1, a positioning groove 11 formed in the middle of the upper end of the fixture table 1, a fixing frame 2 provided at the upper end of the fixture table 1, a hydraulic cylinder 12 fixedly mounted at the upper end of the fixing frame 2, sliding grooves 21 formed on both sides of the fixture table 1, a slider 22 fixedly mounted on the inner side of the lower end of the fixing frame 2, a first rack 23 provided on the outer side of the fixing frame 2, and electric cylinders 3 fixedly mounted on both sides of the lower end of the fixture table 1. A connecting rod 31 is installed at the output end of the electric cylinder 3, and a push rod 32 is fixedly mounted in the middle of the upper end of the connecting rod 31. The connecting rod 31 has a second rack 4 welded on both sides. The output end of the hydraulic cylinder 12 is equipped with a rubber plate 13, which is positioned directly above the positioning groove 11. This allows the sapphire crystal to be pressed and limited by the rubber plate 13. The length of the first rack 23 is less than the length of the second rack 4, which allows the first rack 23 to cooperate with the second rack 4 to limit the position of the fixing frame 2. The first rack 23 is positioned below the second rack 4 and meshes with the second rack 4 to ensure the limiting effect of the fixing frame 2, thus eliminating the trouble of bolt positioning.

[0025] The upper end of the push rod 32 extends through the lower part of the positioning groove 11, and the lower end of the connecting rod 31 fits against the lower end of the fixture table 1, which facilitates the lifting effect of the push rod 32 on the sapphire crystal.

[0026] The size of the slider 22 is adapted to the size of the groove 21, and the slider 22 and the groove 21 are slidably connected. The cooperation between the slider 22 and the groove 21 ensures the stability of the sliding of the fixing frame 2, thereby facilitating the positioning of the sapphire crystal.

[0027] During positioning, the fixed frame 2 is first slid along the slide groove 21 according to the length of the sapphire crystal. Then, the electric cylinder 3 is opened, which drives the connecting rod 31 to move downward, so that the connecting rod 31 is in contact with the lower end of the fixture table 1, and the top rod 32 is flush with the lower end of the positioning groove 11. At the same time, the connecting rod 31 drives the second rack 4 to move, so that the second rack 4 meshes with the first rack 23, thereby limiting the position of the fixed frame 2 after sliding. This eliminates the trouble of the staff using bolts to limit the fixed frame 2 after each adjustment. Then, the hydraulic cylinder 12 drives the rubber plate 13 to limit the sapphire crystal placed in the positioning groove 11, thereby facilitating the processing of the sapphire crystal. After the sapphire crystal is processed, the electric cylinder 3 is controlled to reset, which drives the connecting rod 31 to move upward, so that the connecting rod 31 drives the top rod 32 to move upward. The top rod 32 lifts the sapphire crystal in the positioning groove 11, thereby facilitating the removal of the sapphire crystal by the staff.
