[0021] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Combined with reference Figure 1-Figure 4 The utility model provides an ultra-white tempered glass drilling crack prevention device, which is used for drilling holes in ultra-white glass before tempering. It includes a drilling workbench 1 and a cantilever 2 arranged on the drilling workbench 1. A hollow cylinder 3 is fixedly penetrated on the drilling workbench 1. A vacuum suction cup 4 is fixedly connected to the top of the hollow cylinder 3. A lifting plate 5 is arranged at the lower part of the inner side of the cantilever 2. A hydraulic device 6 for driving the lifting plate 5 to move vertically is arranged on the cantilever 2. An elastic telescopic structure 7 is arranged at the bottom of the lifting plate 5. In the present application, at least two groups of elastic telescopic structures 7 are used. A hollow cylinder 2 8 is arranged at one end of the elastic telescopic structure 7 facing away from the lifting plate 5. A rubber pressing plate 9 is fixedly connected to the bottom of the hollow cylinder 2 8. The rubber pressing plate 9 can be used to press and fix one side of the ultra-white glass. The rubber pressing plate 9 is located just above the vacuum suction cup 4. The vacuum suction cup 4 can be externally connected to a vacuum generating device. The vacuum suction cup 4 can be used to adsorb and fix the other side of the ultra-white glass. This can effectively stabilize the fixed position of the glass and ensure the stability of the drilling.

[0023] A support rod 15 is threadedly connected to the drilling workbench 1, and an anti-skid plate 16 is fixedly connected to the top of the support rod 15. In the present application, a threaded head is provided at one end of the support rod 15, and the support rod 15 can be threadedly connected to the drilling workbench 1 through the threaded head, so that the support rod 15 can be detachable. The support rod 15 cooperates with the position setting of the anti-skid plate 16. When the untempered ultra-white glass is adsorbed and fixed on the vacuum suction cup 4, the anti-skid plate 16 can be used to support other positions of the ultra-white glass, so as to ensure the balance of the supporting force of the ultra-white glass.

[0024] The top of the inner side of the cantilever 2 is fixedly connected with a polished rod 17, and the lifting plate 5 is slidably connected to the polished rod 17. The lifting plate 5 can be slidably connected to the polished rod 17 through a linear bearing, so as to ensure the stability of the vertical operation of the lifting plate 5.

[0025] The elastic telescopic structure 7 includes a telescopic rod 71 fixedly connected to the bottom of the lifting plate 5 and a compression spring 72 sleeved on the telescopic rod 71. The end of the telescopic rod 71 facing away from the lifting plate 5 is fixedly connected to the hollow cylinder 8. When the rubber pressure plate 9 is pressed against the ultra-white glass, the telescopic rod 71 can shrink by itself and the compression spring 72 is in a compressed state.

[0026] Specifically, after the untempered ultra-white glass is fixed on the vacuum suction cup 4, the lifting plate 5 can be driven downward by the hydraulic device 6. At this time, the rubber pressure plate 9 can act on the upper surface of the ultra-white glass to achieve compression. During this process, the telescopic rod 71 shrinks and the compression spring 72 is in a compressed state.

[0027] A hollow tube 10 is arranged in the hollow cylinder 8, and a rotating joint 11 is arranged on the hollow tube 10 and the lifting plate 5. In the present application, the end of the rotating joint 11 facing away from the hollow tube 10 can be externally connected to a cooling water pump body, so that cooling water can be conveniently input into the hollow tube 10. The cooling water can use tap water as the cooling water body. A drill bit 12 is fixedly connected to the bottom end of the hollow tube 10, and a water spray hole 13 is opened on the outer surface of the hollow tube 10. In the present application, an atomizing head can be arranged in the water spray hole 13. By atomizing the cold water, the utilization rate of cooling resources can be improved. A rotating drive unit 14 for driving the hollow tube 10 to rotate is arranged on the lifting plate 5.

[0028] The hollow tube 10 is rotatably connected to the lifting plate 5 via a rotary joint 11 . When the hollow tube 10 drives the drill bit 12 to rotate, the cooling water can be stably transported in the hollow tube 10 .

[0029] The outer surface of the hollow tube 10 is fixedly connected with a shield 18, and the shield 18 is located on the outside of the water spray hole 13. When the water is sprayed in atomized form at the water spray hole 13, the shield 18 can gather the sprayed atomized water toward the drill bit 12, thereby ensuring that the contact position between the drill bit 12 and the glass is in a cooled and moistened state in real time, which can effectively improve the anti-cracking effect of drilling.

[0030] The rotation driving unit 14 includes a drilling motor 141 fixedly connected to the lifting plate 5, a gear 142 fixedly connected to the output end of the drilling motor 141, and a gear 2 143 meshingly connected to the gear 1 142. The gear 2 143 is fixedly connected to the outer surface of the hollow tube 10.

[0031] Specifically, when the lifting plate 5 descends through the hollow tube 10, the drilling motor 141 is started, which drives the gear 142 to engage the transmission gear 2 143 to rotate, so that the drill bit 12 can be opened when it descends and contacts the untempered ultra-white glass. After the ultra-white glass is opened, it can be transferred to the glass tempering process for tempering treatment.

[0032] It is worth noting that, since the original position of the drill bit 12 is located inside the hollow cylinder 8, when the rubber pressure plate 9 acts on the upper surface of the ultra-white glass to achieve compression, during this process, the telescopic rod 71 shrinks by itself and the compression spring 72 is in a compressed state. Since the rubber pressure plate 9 first presses and fixes the ultra-white glass, the drill bit 12 then drills holes in the glass. In this way, the power based on the hydraulic device 6 can cooperate to meet the glass fixing and drilling movement effects.
