[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a dicing machine spindle fastening device provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the first and second gearboxes. Figure 3 for Figure 1The diagram shows a cross-sectional view of the limiting component. A dicing machine spindle fastening device includes: a first gearbox 1, a first rotating shaft 11 rotatably connected to the bottom of the inner side of the first gearbox 1, a first worm gear 12 fixedly installed on the outer side of the first rotating shaft 11, a first worm 13 meshing on one side of the first worm gear 12, and a first rotating rod 14 fixedly installed inside the first worm 13;

[0027] The second gearbox 2 is fixedly installed on the top of the first rotating shaft 11. The interior of both ends of the second gearbox 2 is rotatably connected to the second rotating shaft 21. The outer side of the second rotating shaft 21 is fixedly installed with the second worm gear 3. The top of the second worm gear 3 is meshed with the second worm 32. The interior of the second worm 32 is fixedly installed with the second rotating rod 31.

[0028] Two limiting components 4 are respectively disposed on the outer side of one end of the first rotating rod 14 and the second rotating rod 31. Each limiting component 4 includes two moving rings 42, which are respectively disposed on the outer side of the first rotating rod 14 and the second rotating rod 31. Spring telescopic rods 41 are fixedly installed at both ends of one side of each of the two moving rings 42. The spring telescopic rods 41 are respectively fixedly installed on the front of the first gearbox 1 and the second gearbox 2. A first limiting gear ring 43 is fixedly installed on one side of the moving ring 42. A second limiting gear ring 44 meshes with one side of the first limiting gear ring 43. A rotating frame 45 is fixedly installed on one side of the second limiting gear ring 44. The rotating frame 45 is respectively fixedly installed at one end of the first rotating rod 14 and the second rotating rod 31.

[0029] The other end of the first rotating rod 14 is rotatably connected to the back side of the inner side of the first gearbox 1, and the other end of the second rotating rod 31 is rotatably connected to the back side of the inner side of the second gearbox 2.

[0030] The first rotating rod 14 is rotatably connected to the back of the inner side of the first gearbox 1, which increases the stability of the first rotating rod 14 during rotation. Similarly, the second rotating rod 31 is rotatably connected to the back of the inner side of the second gearbox 2, which increases the stability of the second rotating rod 31 during rotation.

[0031] The second rotating shaft 21 has a mounting groove 22 at one end of its top, and a support frame 23 is fixedly installed at the top end of the second rotating shaft 21. The support frame 23 is internally threaded with a threaded rod 24, and a pressure plate 25 is rotatably connected to the bottom of the threaded rod 24.

[0032] The inner side of the mounting groove 22 is provided with a main shaft 5, and the bottom of the pressure plate 25 abuts against the top of the main shaft 5.

[0033] By placing the spindle 5 on the inner side of the mounting groove 22 and then rotating the threaded rod 24, the threaded rod 24 is threadedly connected inside the support frame 23, thereby driving the pressure plate 25 to move downward, so that the bottom of the pressure plate 25 abuts against the top of the spindle 5, thereby playing the role of limiting the installation of the spindle 5.

[0034] The working principle of the spindle fastening device for a dicing machine provided by this utility model is as follows:

[0035] When using the device, if the user needs to adjust the main shaft 5, they can rotate the rotating frame 45, which is installed at one end of the first rotating rod 14 and the second rotating rod 31. Before rotating the rotating frame 45, the user needs to push the moving ring 42 with one hand, so that the moving ring 42 squeezes the spring telescopic rod 41, thereby driving the first limiting gear ring 43 away from the second limiting gear ring 44. Only then can the user rotate the rotating frame 45 to adjust the main shaft 5. After adjusting to the appropriate position, the user releases the moving ring 42. At this time, the elasticity of the spring telescopic rod 41 will drive the first limiting gear ring 43 and the second limiting gear ring 44 to mesh, thereby limiting the rotating frame 45. In this way, the first rotating rod 14 and the second rotating rod 31 can be limited.

[0036] Compared with related technologies, the spindle fastening device for a dicing machine provided by this utility model has the following advantages:

[0037] The spring telescopic rod 41 pushes the moving ring 42, causing the first limiting gear ring 43 and the second limiting gear ring 44 to mesh, thereby limiting the rotating frame 45. This limits the first rotating rod 14 and the second rotating rod 31, thus preventing the main shaft 5 from shifting due to accidental contact with the rotating rod by the operator during subsequent use, thereby increasing the stability of the fastening device.

[0038] Example 2

[0039] Please refer to the following: Figure 4 Based on the first embodiment of this application providing a spindle fastening device for a dicing machine, the second embodiment of this application proposes another spindle fastening device for a dicing machine. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0040] Specifically, the difference in the second embodiment of this application regarding the spindle fastening device for a dicing machine is that the bottom of the pressure plate 25 of the spindle fastening device for a dicing machine is provided with a rubber pad 6.

[0041] The bottom of the rubber pad 6 has grooves 61 at both ends, and a locking screw 62 is provided on the inner side of the groove 61.

[0042] The top of the locking screw 62 is threaded to the bottom of the pressure plate 25.

[0043] After prolonged use, when the rubber pad 6 is severely worn, the user can rotate the locking screw 62 to disengage the top of the locking screw 62 from the bottom thread of the pressure plate 25, and then the rubber pad 6 can be disassembled and replaced.

[0044] The working principle of the spindle fastening device for a dicing machine provided by this utility model is as follows:

[0045] When the pressure plate 25 is moved downward, the bottom of the rubber pad 6 can come into contact with the top of the spindle 5, thereby limiting and fixing the spindle 5.

[0046] Compared with related technologies, the spindle fastening device for a dicing machine provided by this utility model has the following advantages:

[0047] The rubber pad 6, groove 61, and locking screw 62 work together to ensure that the bottom of the rubber pad 6 abuts against the top of the spindle 5 during use, thereby protecting the spindle 5 and preventing wear on its surface.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
