Technical Field
[0001] This utility model relates to the field of glass processing technology, and in particular to a CNC cutting and cooling device for optical glass. Background Technology
[0002] Optical glass is a highly homogeneous type of glass, which is used as a material for optical elements that transmit images through the reflection and refraction of light, such as lenses and prisms.
[0003] During the glass cutting process, the friction between the cutter and the glass generates heat at the cutting point. In particular, the cutting edge of the cutter is subject to continuous cutting friction over a long period of time, which affects the use of the cutter and reduces its lifespan. Therefore, this application discloses a cooling device for CNC cutting of optical glass. Utility Model Content
[0004] The purpose of this invention is to address existing problems by providing a cooling device for CNC cutting of optical glass.
[0005] This utility model is achieved through the following technical solution: a CNC cutting and cooling device for optical glass, comprising a CNC machine head, the upper end of a tool holder connected to the lower end of the CNC machine head, a tool holder fitted inside the tool holder, the upper end of the tool holder fitted inside a rod sleeve, the upper end of the tool holder connected to the lower end of a cone, the upper end of the cone connected to a spring groove, a spring vertically arranged in the spring groove, the upper end of the spring abutting against the CNC machine head, a cutting wheel rotatably connected in the groove at the lower end of the tool holder, a roller of a valve-connecting mechanism contacting the outer curved surface on one side of the cone, the valve-connecting mechanism being installed on the inner wall of the tool holder, an inlet pipe and an outlet pipe connected to the valve-connecting mechanism, a nozzle connected to the end of the outlet pipe, the nozzle being aligned with the lower side of the cutting wheel.
[0006] As a further improvement to the above solution, the valve passage mechanism includes a roller, which is rotatably connected to the front end of a slide rod. The slide rod is movably fitted inside a sleeve, and the end of the sleeve away from the slide rod is connected to the inner wall of the tool holder. A second spring is installed inside the sleeve, with its two ends respectively abutting against the inner wall of the tool holder and the end of the slide rod near the sleeve. A tube seat is symmetrically installed at the end of the sleeve away from the tool holder. As the space where the roller is blocked changes, the roller and the slide rod are displaced, and the slide rod is displaced within the sleeve by the action of the second spring.
[0007] As a further improvement to the above solution, the upper end of the tool holder is provided with an external thread, and the upper end of the tool holder is connected to the CNC machine head through its external thread for detachable connection and convenient disassembly.
[0008] As a further improvement to the above solution, a through hole is provided on the slide rod to guide the coolant in the inlet pipe to the outlet pipe.
[0009] As a further improvement to the above solution, both the inlet pipe and the outlet pipe are fitted with a sleeve, which is connected through and fixed to the cutter holder. The inlet pipe and the outlet pipe are fixed to the cutter holder through the sleeve.
[0010] As a further improvement to the above solution, a pipe clamp is installed on the liquid outlet pipe, the pipe clamp is connected to the support rod, and the support rod is connected to the lower end of the outer curved surface of the knife holder, which is used to fix the liquid outlet pipe with the pipe clamp, and the liquid outlet pipe is supported and fixed by the support rod.
[0011] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. The CNC machine head drives the tool holder, tool holder and tool wheel to move downward. The tool wheel presses against the optical glass. During the downward movement of the roller, it is also subjected to the force of spring two and moves laterally through the slide rod. The through hole in the slide rod conducts the liquid inlet pipe and liquid outlet pipe, so that the coolant in the water pipe is sprayed from the nozzle onto the cutting trajectory of the optical glass under the tool wheel, thereby cooling down the heat generated during the cutting of the optical glass and ensuring the service life of the cutter.

[0017] like Figures 1 to 4 As shown, a CNC cutting and cooling device for optical glass includes a CNC head 1. The upper end of a tool holder 2 is connected to the lower end of the CNC head 1. A tool holder 4 is fitted inside the tool holder 2. The upper end of the tool holder 4 is fitted inside a sleeve 3. The sleeve 3 is connected to the lower end of the tool holder 2. The upper end of the tool holder 4 is connected to the lower end of a cone 12. The upper end of the cone 12 is connected to a spring groove 13. A spring 14 is vertically installed in the spring groove 13. The upper end of the spring 14 abuts against the CNC head 1. A tool wheel 5 is rotatably connected in the groove at the lower end of the tool holder 4. A roller 94 of a valve passage mechanism 9 contacts the outer curved surface of one side of the cone 12. The valve passage mechanism 9 is installed on the inner wall of the tool holder 2. An inlet pipe 11 and an outlet pipe 7 are connected to the valve passage mechanism 9. The end of the outlet pipe 7 is connected to a nozzle 6. The nozzle 6 is aligned with the lower side of the tool wheel 5.
[0018] As a further improvement to the above solution, the valve passage mechanism 9 includes a roller 94, which is rotatably connected to the front end of the slide rod 93. The slide rod 93 is movably fitted inside the sleeve 91. The end of the sleeve 91 away from the slide rod 93 is connected to the inner wall of the tool holder 2. A second spring 92 is installed inside the sleeve 91. The two ends of the second spring 92 respectively abut against the inner wall of the tool holder 2 and the end of the slide rod 93 near the sleeve 91. A tube seat 5 is symmetrically arranged on the end of the sleeve 91 away from the tool holder 2. As the space where the roller 94 is blocked changes, the roller 94 and the slide rod 93 are displaced. The slide rod 93 is displaced inside the sleeve 91 by the action of the second spring 92.
[0019] As a further improvement to the above solution, the upper end of the tool holder 2 is provided with an external thread 21, and the upper end of the tool holder 2 is connected to the CNC machine head 1 through its external thread 21 for detachable connection and convenient disassembly.
[0020] As a further improvement to the above solution, a through hole 96 is provided on the slide rod 93 to guide the coolant in the inlet pipe 11 to the outlet pipe 7.
[0021] As a further improvement to the above solution, both the inlet pipe 11 and the outlet pipe 7 are fitted with a sleeve 10, which is connected through and fixed to the tool holder 2. The inlet pipe 11 and the outlet pipe 7 are fixed to the tool holder 2 through the sleeve 10.

The pipe clamp is used to fix the liquid outlet pipe 7, and the liquid outlet pipe 7 is supported and fixed by the support rod.
[0023] The working principle of a CNC cutting cooling device for optical glass is as follows: The CNC head 1 drives the tool holder 2, tool holder 4, and tool wheel 5 to move downward. The tool wheel 5 presses against the optical glass. During the downward movement, the roller 94 is also subjected to the force of the spring 2 92 and moves laterally through the slide rod 93. The through hole in the slide rod 93 connects the liquid inlet pipe 11 and the liquid outlet pipe 7, so that the coolant in the water pipe is sprayed from the nozzle 6 onto the cutting trajectory of the optical glass under the tool wheel 5, thereby cooling the heat generated during the cutting of the optical glass.
