Description

Technical Field

[0001] This utility model belongs to the field of optical glass processing technology, specifically relating to a side processing machine for optical glass. Background Technology

[0002] Optical glass is a special glass material used to manufacture optical components. It possesses excellent optical properties and characteristics, and components made of optical glass are key elements in optical instruments, playing a vital role in the field of optics. However, optical glass requires grinding and polishing of its edges during processing.

[0003] Chinese patent document CN222222094U discloses a semi-automatic side processing machine for optical glass. It uses an optical glass adsorption component set inside a rotary table to firmly adsorb optical glass. During the grinding and polishing process, a servo motor can drive the rotary table to rotate, so that the optical glass rotates with the rotation of the rotary table, which facilitates the adjustment of the orientation of the optical glass.

[0004] However, in the existing technology, when processing optical glass with regular shape, such as circular optical glass, if the optical glass is not placed in the center on the table that fixes it and allows it to rotate, the position of the grinding component needs to be readjusted every time the optical glass is rotated. Therefore, a side processing machine for optical glass is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a side processing machine for optical glass.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A side processing machine for optical glass includes a frame that ensures stable operation of the machine, a support assembly that holds the optical glass to be processed on the side and drives it to rotate inside the frame, a limiting assembly that enables the machine to continuously process the optical glass above the support assembly, and a grinding assembly that can process the side of the optical glass according to production needs on one side of the frame.

[0008] The support assembly includes a turntable housed within the frame;

[0009] The limiting assembly includes a positioning component that allows the optical glass to be processed by the grinding component in a central position on the turntable, an adjusting component that can adjust the position of the positioning component according to the size of the optical glass, and a pressure application component that can cooperate with the support assembly to clamp the optical glass.

[0010] The positioning component includes a bracket fixedly installed in the frame, a guide rail fixedly connected to the outer side of the bracket, a slider movably connected to the guide rail, multiple screw holes on the slider, a limit rod below the slider, and a rubber sleeve fixedly connected to the outer side of the limit rod.

[0011] Preferably, the adjusting component includes a second electric push rod fixedly mounted on the bracket, a transmission block is fixedly connected to the telescopic end of the second electric push rod, and a transmission rod is provided between the slider and the transmission block.

[0012] Preferably, the pressure-applying component includes a cylinder fixedly installed below the bracket, a connector fixedly connected to the telescopic end of the cylinder, a rotating rod movably connected below the connector, a pressure plate fixedly connected to the lower end of the rotating rod, and a pressure pad fixedly connected to the lower side of the pressure plate.

[0013] Preferably, the guide rail and the slider are slidably connected, and the slider and the limiting rod are connected by threads.

[0014] Preferably, both the slider and the transmission block are rotatably connected to the transmission rod.

[0015] Preferably, the joint is rotatably connected to the rotating rod.

[0016] Preferably, the vertical center lines of the turntable, support, rotating rod, and pressure plate all coincide.

[0017] The beneficial effects of this utility model are as follows: Before clamping and fixing the optical glass, the sliders set at different positions on the bracket and able to move synchronously under the action of the adjustment component allow each limiting rod to move towards the optical glass while maintaining the same distance from the vertical center line of the turntable until each rubber sleeve contacts the optical glass. This ensures that when the optical glass rotates with the turntable, all parts of its side can maintain the same distance from the grinding component. Thus, the machine does not need to frequently adjust the position of the grinding component relative to the optical glass. Combined with the setting of the screw holes, the machine can process optical glass of more sizes and types. Attached Figure Description

[0030] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0031] like Figures 1-7 As shown, a side processing machine for optical glass includes a frame 1 that ensures stable operation of the machine. Inside the frame 1, there is a support assembly 2 that can hold the optical glass to be processed on the side and drive it to rotate. Above the support assembly 2, there is a limiting assembly 3 that enables the machine to continuously process the optical glass. On one side of the frame 1, there is a grinding assembly 4 that can process the side of the optical glass according to production needs.

[0032] In this embodiment, the frame 1, which has a large coverage area on its lower side, provides installation positions for some components of the support assembly 2, the limiting assembly 3, and the grinding assembly 4, so that optical glass of various sizes can be placed in this processing machine for processing according to production needs, and provides a guarantee for the stable operation of this processing machine.

[0033] In this embodiment: the support assembly 2 includes a vertical pole 201 movably connected to the frame 1, a lifting platform 202 fixedly connected above the vertical pole 201, a nut 203 provided on the outer side of the vertical pole 201, a first electric push rod 204 provided below the lifting platform 202, a bearing seat 205 fixedly installed above the lifting platform 202, a turntable 206 movably connected to the bearing seat 205, a first motor 207 fixedly connected below the turntable 206, and a support pad 208 fixedly connected to the upper side of the turntable 206;

[0034] The frame 1 is slidably connected to the upright 201, the upright 201 is threadedly connected to the nut 203, and the bearing 205 is rotatably connected to the turntable 206.

[0035] The movable range of the lifting platform 202 is limited by the upright 201, so that it can only rise and fall after the first electric push rod 204 is working. When the nut 203 contacts the frame 1, it can prevent the height of the lifting platform 202 from being accidentally reduced. The lifting platform 202 provides an installation position for the bearing seat 205 and the first motor 207. The movable range of the turntable 206 is limited by the bearing seat 205, so that it can only rotate around its own vertical center line after the first motor 207 is working. The optical glass is supported by the pad 208 instead of the turntable 206, so as to provide sufficient friction to limit the horizontal movement of the optical glass and prevent the optical glass from being damaged by collision with the turntable 206 when it is placed.

[0036] In this embodiment: the limiting component 3 includes a positioning component that allows the optical glass to be processed by the grinding component 4 at the center position on the turntable 206, an adjusting component that can adjust the position of the positioning component according to the size of the optical glass, and a pressure application component that can cooperate with the support component 2 to clamp the optical glass.

[0037] The positioning component includes a bracket 301 fixedly installed in the frame 1. A guide rail 302 is fixedly connected to the outer side of the bracket 301. A slider 303 is movably connected to the guide rail 302. Multiple screw holes 304 are provided on the slider 303. A limit rod 305 is provided below the slider 303. A rubber sleeve 306 is fixedly connected to the outer side of the limit rod 305. The adjusting component includes a second electric push rod 307 fixedly installed on the bracket 301. A transmission block 308 is fixedly connected to the telescopic end of the second electric push rod 307. A transmission rod 309 is provided between the slider 303 and the transmission block 308. The pressure component includes a cylinder 310 fixedly installed below the bracket 301. A connector 311 is fixedly connected to the telescopic end of the cylinder 310. A rotating rod 312 is movably connected below the connector 311. A pressure plate 313 is fixedly connected to the lower end of the rotating rod 312. A pressure pad 314 is fixedly connected to the lower side of the pressure plate 313.

[0038] The guide rail 302 is slidably connected to the slider 303, the slider 303 is threadedly connected to the limit rod 305, the slider 303 and the transmission block 308 are rotatably connected to the transmission rod 309, the joint 311 is rotatably connected to the rotating rod 312, and the vertical center lines of the turntable 206, the bracket 301, the rotating rod 312 and the pressure plate 313 are all coincident.

[0039] The bracket 301 provides mounting positions for the guide rail 302, the second electric actuator 307, and the cylinder 310. The guide rail 302 restricts the movable range of the slider 303, allowing it to slide along the guide rail 302 only after the second electric actuator 307 is activated, driven by the transmission block 308 and the transmission rod 309. The slider 303 with the screw hole 304 installs the limiting rod 305, allowing each limiting rod 305 to be suspended at the same distance in different directions on the turntable 206. The rubber sleeve 306 replaces the limiting rod 305 in contact with the side of the optical glass to prevent damage when the optical glass is clamped. The length change of the extension end of the cylinder 310 is transmitted to the pressure plate 313 via the rotating rod 312 through the connector 311. The rotating rod 312 allows the pressure plate 313 to rotate above the turntable 206. The pressure pad 314 replaces the pressure plate 313 in contact with the optical glass.

[0040] In this embodiment: the grinding assembly 4 includes two arc-shaped frames 401 fixedly connected to one side of the frame 1. A limiting groove 402 is integrally formed on the side of the arc-shaped frame 401 away from the other arc-shaped frame 401. A rack 403 is fixedly connected to the side of the arc-shaped frame 401 away from the frame 1. A reversing frame 404 is movably connected between the two arc-shaped frames 401. A second motor 405 is fixedly installed at the front and rear of the reversing frame 404. A gear 406 is fixedly connected to the output end of the second motor 405. A third electric push rod 407 is fixedly installed on one side of the reversing frame 404. A slide 408 is fixedly connected to the telescopic end of the third electric push rod 407. A third motor 409 is fixedly installed inside the slide 408. A grinding disc 410 is fixedly connected to the output end of the third motor 409.

[0041] The arc frame 401 and the slide 408 are slidably connected to the reversing frame 404, and the rack 403 is meshed with the gear 406.

[0042] The movable range of the reversing frame 404 is limited by the arc-shaped frame 401 with the limiting groove 402. The second motor 405 drives the gear 406 to rotate. Through the interaction between the rack 403 and the rotating gear 406, the reversing frame 404 can drive the third electric push rod 407, the slide 408 and other components to move along the arc-shaped frame 401. The third electric push rod 407 adjusts the distance between the slide 408 and the center of the frame 1. The slide 408 provides an installation position for the third motor 409 that can drive the grinding disc 410 to rotate. The rotating grinding disc 410 contacts the side of the optical glass and grinds its side.

[0043] Working Principle: When this processing machine is installed for side processing of optical glass, the height of the lifting platform 202 can be adjusted by operating the first electric actuator 204 according to the thickness of the optical glass. Then, the nut 203 is rotated to contact the frame 1 to prevent the height of the lifting platform 202 from accidentally decreasing. After adjustment, the optical glass is placed on the support pad 208, and the horizontal position of the slider 303 is adjusted by operating the second electric actuator 307, allowing the rubber sleeve 306 to contact the optical glass from different angles. Once all rubber sleeves 306 are in contact with the optical glass, the optical glass is centered above the support pad 208. At this point, the cylinder 310 can be activated to press the pressure pad 314 onto the optical glass, thus fixing the optical glass. During the centering process, if the slider 303 moves to its limit position on the guide rail 302 but still cannot contact the optical glass, the limit rod 305 can be removed and its inserted screw hole 304 adjusted to further adjust the horizontal position of the limit rod 305.

[0044] After the optical glass is fixed, the rubber sleeve 306 is no longer in contact with the optical glass. Then the first motor 207 can be made to drive the optical glass clamped between the support pad 208 and the pressure pad 314 to rotate. Then the grinding component 4 grinds the side of the optical glass.

[0045] During polishing, while the third motor 409 drives the polishing disc 410 to rotate continuously, the third electric push rod 407 adjusts the distance between the polishing disc 410 and the side of the optical glass, and the second motor 405 adjusts the angle of the polishing disc 410 relative to the optical glass, thereby realizing the adjustment of the polishing amount and polishing angle of this processing machine.

[0046] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
