[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figure 1-5A sapphire glass cutting device for watches includes a support plate 1, a transmission seat 2 fixedly connected to the top of one end of the support plate 1, a transmission screw 3 rotatably connected to the inner side of the transmission seat 2, a transmission motor 4 fixedly connected to one end of the transmission seat 2, and the output end of the transmission motor 4 fixedly connected to the transmission screw 3, a displacement frame 5 threadedly connected to the outer side of the transmission screw 3, a cutting shaft 6 rotatably connected to the top of the displacement frame 5, a cutting disc 7 fixedly connected to one end of the cutting shaft 6, a transmission assembly 8 provided at the top of the inner side of the transmission seat 2, the transmission assembly 8 being used to drive the cutting disc 7 to rotate, a bar support frame 9 fixedly connected to the other end of the top of the support plate 1, a positioning assembly 10 provided at one end of the bar support frame 9, and the positioning assembly 10 being used to cooperate with the bar support frame 9 to position the sapphire glass bar.

[0028] In this embodiment, a limiting slide rod is fixedly connected to the bottom of the inner side of the transmission seat 2, and the displacement frame 5 is also slidably connected to the outside of the limiting slide rod. By setting the limiting slide rod, the displacement of the displacement frame 5 can be effectively guided, and uncontrollable displacement of the displacement frame 5 can be avoided.

[0029] The transmission assembly 8 includes a central shaft 11, a linkage shaft 12, and a transmission bevel gear 13. The central shaft 11 is rotatably connected to the top of the inner side of the transmission seat 2. The linkage shaft 12 is rotatably connected to the top of the transmission motor 4 near the central shaft 11, and the linkage shaft 12 is also slidably connected to the outside of the central shaft 11. The transmission bevel gear 13 is fixedly connected to the outside of the linkage shaft 12. The other end of the cutting shaft 6 is fixedly connected to an acceleration bevel gear 14, and the acceleration bevel gear 14 meshes with the transmission bevel gear 13. One end of the transmission screw 3 and the central shaft 11 are both fixedly connected to a transmission sprocket 15, and the two transmission sprockets 15 are connected by a chain.

[0030] In this embodiment, the linkage rod 12 is a hollow structure. A limiting strip is fixedly connected to the outer side of the central shaft rod 11. A limiting groove is formed on the inner wall of the linkage rod 12, and the limiting strip is also slidably connected inside the limiting groove. Through the connection between the limiting strip and the limiting groove, when the linkage rod 12 slides along the central shaft rod 11, the displacement of the linkage rod 12 can be guided by the limiting strip. When the central shaft rod 11 rotates, the linkage rod 12 can be driven to rotate by the limiting strip.

[0031] In this embodiment, the diameter of the transmission bevel gear 13 is larger than the diameter of the acceleration bevel gear 14. By changing the diameters of the transmission bevel gear 13 and the acceleration bevel gear 14, the cutting shaft 6 can rotate faster, ensuring the cutting efficiency of the cutting disc 7.

[0032] Example 2:

[0033] Please see Figure 1-5This embodiment provides a technical solution based on embodiment one: the positioning component 10 includes an extension frame 16, a positioning shaft 17, and a guide plate 18. One end of the bar stock support frame 9 is fixedly connected to the extension frame 16, the top of one side of the extension frame 16 is fixedly connected to the positioning shaft 17, the outer side of the positioning shaft 17 is rotatably connected to the guide plate 18, the middle of the guide plate 18 is provided with a guide groove 19, the top of the extension frame 16 is fixedly connected to an extension piece, the middle of the extension piece is vertically slidably connected to a positioning rod 20, the bottom end of the positioning rod 20 is fixedly connected to a positioning plate 21, and the top of the positioning plate 21 and the extension piece are fixedly connected to a helical spring 22.

[0034] In this embodiment, a pressure rod is fixedly connected to the top of the positioning rod 20. The positioning rod 20 is movably connected to the inside of the guide groove 19 through the pressure rod. The setting of the pressure rod enables the positioning rod 20 and the guide groove 19 to be effectively assembled, avoiding motion interference.

[0035] In this embodiment, the positioning plate 21 has an arc-shaped structure, and the bottom end of the positioning plate 21 is provided with anti-slip texture. Through the structural characteristics of the positioning plate 21, it can have a greater contact with the sapphire glass rod.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] Working principle: First, the sapphire glass rod is placed on the top of the rod support frame 9. Then, the guide plate 18 is pressed down, causing the guide plate 18 to rotate under the support of the positioning shaft 17. Since the top of the positioning rod 20 is also movably connected to the inside of the guide slot 19, when the guide plate 18 rotates, it can drive the positioning plate 21 to contact the sapphire glass rod, so as to position the sapphire glass rod between the rod support frame 9 and the positioning plate 21.

[0038] Subsequently, the drive motor 4 is started to drive the drive screw 3 to rotate, and the power of the drive screw 3 is transmitted to the central shaft 11 through the chain, causing the central shaft 11 to rotate at the same time. The central shaft 11 drives the linkage shaft 12 to rotate, causing the drive bevel gear 13 to move the acceleration bevel gear 14, so as to drive the cutting disc 7 to rotate under the support of the cutting shaft 6. At the same time, with the connection between the drive screw 3 and the displacement frame 5, the displacement frame 5 is moved along the drive screw 3. When the cutting disc 7 comes into contact with the sapphire glass rod, the sapphire glass rod can be cut through the cutting disc 7.

[0039] After a single cut, the guide plate 18 is released. As the positioning rod 20 moves, it can cause the spiral spring 22 to deform. After the guide plate 18 is released, the positioning plate 21 can be pulled by the spiral spring 22, causing the positioning plate 21 to move away from the sapphire glass rod.
