[0001] The utility model relates to the technical field of four-axis precision engraving machines for optical glass, and particularly relates to a four-axis precision engraving machine for optical glass. Background Technique

[0002] A four-axis precision engraving machine for optical glass is a high-precision mechanical device specially used for precision machining of optical glass. It combines advanced numerical control technology and precision machining technology, and can realize precision engraving, cutting, drilling, polishing and other operations on optical glass. Compared with the traditional three-axis precision engraving machine, the four-axis precision engraving machine adds a rotating axis (generally called the A axis or C axis), which can perform more complex spatial machining, improve the flexibility and precision of machining, and is especially suitable for high-precision machining of optical components.

[0003] During the use of the current four-axis precision engraving machine for optical glass by staff, it is often found that: currently, the optical glass on the four-axis precision engraving machine is usually clamped and limited by a fixture. After a piece of optical glass is processed, the machine needs to be turned off, and the staff needs to remove the processed glass and then reinstall a new glass for processing. Repeatedly turning the machine on and off in this way easily leads to a reduction in processing efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a four-axis precision engraving machine for optical glass is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a four-axis precision engraving machine for optical glass, including a frame, a gantry is slidably connected to the frame, a slider is slidably connected to the gantry, a sliding rod is slidably connected to the slider, a first motor is fixedly connected to the sliding rod, a processing tool is fixedly connected to the output shaft of the first motor, a second motor is fixedly connected to the frame, a rotating plate is fixedly connected to the output shaft of the second motor, a plurality of first vacuum suction cups are fixedly connected to the rotating plate, a feeding structure is arranged on the frame, the feeding structure is mainly composed of a placing plate, the placing plate is fixedly connected to the frame, a plurality of placing grooves are opened on the placing plate, a chute is opened on the frame, a sliding rod is slidably connected in the chute, a rotating rod is rotatably connected to the sliding rod, a cylinder is fixedly connected to the rotating rod, a rectangular plate is fixedly connected to the piston rod of the cylinder, and a plurality of second vacuum suction cups are fixedly connected to both surfaces of the rectangular plate.

[0006] The effects achieved by the above components are as follows: Place the optical glass on the rotating plate. Through the vacuum pump, several first vacuum suction cups adsorb the glass. Drive the gantry to slide on the frame through the internal drive assembly, the slider to slide on the gantry, and the sliding rod to slide on the slider to adjust the processing tool to a suitable processing position. Start the first motor, and the output shaft of the first motor drives the processing tool to rotate to process the glass. During the processing, start the second motor, and the output shaft of the second motor drives the rotating plate to rotate to adjust the angle of the glass. Place several optical glasses in the placement slots respectively. Slide the sliding rod to make the rectangular plate in a suitable position. Start the cylinder, and the piston rod of the cylinder drives the rectangular plate to descend. Then start the vacuum pump to make several second vacuum suction cups adsorb the glass. Then start the cylinder to drive the rectangular plate to rise. Then rotate the rotating rod to make the rectangular plate in a horizontal state. Then move the sliding rod to make the processed glass contact the second vacuum suction cups that do not adsorb the glass, so that the second vacuum suction cups adsorb the processed glass. At this time, one side of the rectangular plate is the processed glass, and the other side is the glass to be processed. Rotate the rotating rod by 180 degrees, place the glass to be processed on the first vacuum suction cups, and place the processed glass in the placement slot. It can achieve rapid loading and unloading without shutting down the machine, thus avoiding the situation where the processing efficiency is easily reduced due to the fact that on the current four-axis precision engraving machine for optical glass, the optical glass is usually clamped and limited by a fixture. After one piece of optical glass is processed, the machine needs to be shut down, and the staff needs to remove the processed glass and then reinstall a new glass for processing. Repeatedly turning the machine on and off like this is likely to lead to a reduction in processing efficiency.

[0015] Preferably, a cleaning structure is provided on the frame. The cleaning structure is mainly composed of a blanking chute, which is opened on the frame, and two scraping plates are slidably connected to the frame.

[0016] The effects achieved by the above components are as follows: During the engraving process, the generated debris and cutting fluid fall on the frame. Two scraping plates can be slid simultaneously to push the sundries to the blanking chute for dropping. The staff can place a collection box under the blanking chute for collection.

[0017] Preferably, racks are fixedly connected to the scraping plates, and a gear is commonly meshed with the two racks.

[0018] The effects achieved by the above components are as follows: Rotating the gear can drive the two racks to move synchronously and in opposite directions, making the cleaning operation more convenient.

[0019] Preferably, a fifth motor is fixedly connected to the frame, and the output shaft of the fifth motor is fixedly connected to the gear.

Slide the sliding rod to make the rectangular plate located at a suitable position. Start the air cylinder, and the piston rod of the air cylinder drives the rectangular plate to descend. Then start the vacuum pump so that several second vacuum suckers suck the glasses. Then start the air cylinder to drive the rectangular plate to rise. Then rotate the rotating rod to make the rectangular plate in a horizontal state. Then move the sliding rod to make the processed glass contact with the second vacuum suckers that have not adsorbed the glass, so that the second vacuum suckers suck the processed glass. At this time, one side of the rectangular plate is the processed glass, and the other side is the glass to be processed. Rotate the rotating rod by 180 degrees, place the glass to be processed on the first vacuum sucker, and place the processed glass in the placing groove. It can realize rapid loading and unloading without shutting down the machine. Clamp several glasses in several rectangular grooves to further limit the position of the glasses and make their positions more stable.
