[0002] Optical crystals are crystal materials used as optical medium materials. They are mainly used to make windows, lenses and prisms in the ultraviolet and infrared regions. According to the crystal structure, they are divided into single crystals and polycrystalline. Since single crystal materials have high crystal integrity and light transmittance, as well as low input loss, commonly used optical crystals are mainly single crystals. For example, when it comes to common lenses on the market, their gloss and transparency can be restored by repairing surface damage.

[0003] For example, the public document CN115365551B discloses a milling repair device for optical crystal surface damage, comprising a repair platform, a carrier frame fixedly mounted at the rear edge of the upper end surface of the repair platform, two sets of reinforcing ribs fixedly mounted on both sides of the carrier frame, the lower ends of the reinforcing ribs are fixedly connected to the repair platform, a milling part is mounted at the front end of the carrier frame, a clamping part is mounted in front of the upper end carrier frame of the repair platform, and the clamping part is connected to the milling part.

[0008] The transmission gear of the present invention is a gear selected from the group consisting of a gearbox and a gearbox, wherein the gearbox has two guide wheels, the guide wheels having a first end in contact with the first wheel and a second end in contact with the first gear.

[0012] Preferably, the driving gear is meshed with two sets of rack racks, which are slidably arranged with the limiting slide bars respectively. The front set of the two sets of positioning rings is movably sleeved between the No. 1 auxiliary transmission gear and the joint on the outer side of the slide bar, and the other set of the two sets of positioning rings is arranged between the No. 2 auxiliary transmission gear and the upper disc of the milling cutter head.

[0013] Preferably, a soft grinding plate is provided on the outer side of the airbag, the sliding rod is provided with an elastic line fixedly connected to the inner bottom of the airbag, the sliding rod and the connecting seat are slidingly arranged and pass through the inner side of the connecting seat, and an air outlet is opened on the lower side of the sliding rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Place the protruding side of the optical lens into the model groove. When placing it the other way around, it is necessary to insert the die seat, cover the optical lens on the upper end of the die seat, and then start several sets of hydraulic cylinders to work, lift the upper top plate upward, and the side of the top plate will push the lower position of several sets of control rods, and at the same time rotate outward along the circular axis, and several sets of clamps will be driven by the control rods and clamped on the side position of the optical lens, and the lower position of several sets of control rods will stretch several sets of double-hook springs to achieve the purpose of fixing the optical lens and facilitate surface repair.

[0017] After the milling cutter head is lowered, when the side of the optical lens is rotated, at this time, the column gear is controlled to rotate by motor No. 1. Since the column gear and the gear ring are in meshing state, the ring seat rotates along the positioning ring, driving the hydraulic cylinder and the top plate on the upper side to rotate at the same time. When the notch corresponds to a set of control rods during the rotation, the control rod will be pulled to the lower side by the stretched double-hook spring, so that the upper position and the fixed clamping block are rotated and opened. The notch corresponds to the milling cutter head, so when the top plate rotates, the drive motor at the upper end of the mounting seat controls the electric slide and the positioning assembly to rotate as a whole, so that when the milling cutter head grinds and repairs the optical lens, whenever it approaches a set of clamping blocks, the notch will cause it to rotate open, and when the milling cutter head moves, it will be lifted up by the top plate again, avoiding direct clamping of the concave and convex sides of the optical lens, which is easy to damage. At the same time, clamping of the sides is achieved to avoid side repair work.

[0018] The airbag is connected to an external air pump through a joint, and the inside of the airbag is inflated through a sliding rod. It does not need to be filled, so that it can be in a slightly relaxed state to better fit the optical lens with the convex surface facing up for deformation. At the same time, the elastic line pulls the sliding rod, the No. 1 auxiliary transmission gear, the positioning ring on the front side, and the rack frame downward, just to make the No. 1 auxiliary transmission gear mesh with the main transmission gear, and the other set of rack frames will be driven to move upward. The driven gear No. 2 will be disconnected from the main transmission gear, and a single pair of airbags will be driven to rotate to grind and repair the surface of the optical lens. When facing a concave optical lens, the airbag can be completely filled with gas to make the lower end become an arc surface. The plasticity of the elastic rope maintains the connection between the No. 1 auxiliary transmission gear and the main transmission gear, and cooperates with the drive motor at the upper end of the mounting seat and the electric slide, so that the airbag works on different positions of the surface, thereby achieving the purpose of processing the concave and convex surfaces of the optical lens.

A single pair of air bags 57 is driven to rotate to grind and repair the surface of the optical lens 36.
