Description

Technical Field

[0001] This utility model relates to the field of lens polishing technology, specifically to an adaptive lens polishing mechanism. Background Technology

[0002] Lens polishing is the most critical process in lens manufacturing. It removes the damaged layer from fine grinding to achieve the specified surface roughness requirements and refines the surface shape to meet the specified surface shape (aperture and local tolerances) requirements.

[0003] In related technologies, a lens grinding and polishing device (publication number CN219562505U) was found to have a solution that uses a limiting block, a rotating mounting plate, and a fixing ring. When the polishing precision of the polishing surface needs to be adjusted, a grinding head of different precision needs to be replaced. The limiting block is rotated by a connecting shaft, so that the limiting block is in the limiting groove. After the limiting block rotates, it is restricted and fixed with the upper surface of the limiting groove, so that the grinding head can be stably assembled and fixed.

[0004] However, in the above scheme, when the shape of the lens does not match the shape of the grinding head after the grinding head is fixedly installed, the grinding area of ​​the lens is limited, resulting in reduced lens grinding efficiency. It is necessary to continuously adjust the position of the grinding head to complete the full grinding of the lens, and it is not adaptable to lenses of different specifications. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive lens polishing mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adaptive lens grinding mechanism, including a drive head, the drive head being Y-shaped, with two fixed caps rotatably mounted on the lower end of the drive head, and a lifting locking device mounted on the upper surface of the fixed caps. The Y-shaped drive head provides space for the movement of the grinding head, allowing the grinding head to better fit the lens.

[0007] The housing is provided in two parts and installed on the upper surface of the fixed cap. A locking rod is inserted into the housing. The locking rod is connected to the lifting locking device and passes through the housing. The lifting locking device keeps the locking rod locked in the state of the grinding head, realizing the assembly of the grinding head and the fixed cap, and also facilitating the replacement of the grinding head.

[0008] The tensioner is rotatably connected to the drive head and the housing at its upper and lower ends. The tensioner controls the balance of the fixed cap. When the grinding head is tilted, the tensioner can apply pressure to the grinding head to ensure stable contact between the grinding head and the lens and to guarantee the grinding effect.

[0009] Furthermore, a grinding head is installed in the fixing cap, and a locking hole corresponding to the locking rod is provided on the side of the grinding head. The locking rod connects and separates from the locking hole by translation, thereby completing the fixing and disassembly of the grinding head.

[0010] Furthermore, the lifting locking device includes a stud, a tightening cap screwed onto the stud, and an adapter sleeve fitted onto the stud. A push-pull rod is rotatably connected between the adapter sleeve and the locking rod. When the locking rod is inserted into the locking hole and the tightening cap is turned to lock the adapter sleeve, the adapter sleeve restricts the movement of the locking rod through the push-pull rod, ensuring that the grinding head is installed stably and that the grinding head will not loosen during the grinding process.

[0011] Furthermore, the tensioner includes a sleeve and a sliding rod inserted into the sleeve. A spring is connected between the sliding rod and the sleeve. A fixing head is screwed to the upper end of the sleeve. The fixing head is fixedly connected to the upper end of the spring. The spring can fix the sliding rod. The force of the spring is applied to the fixing cap through the sliding rod. The fixing cap makes the grinding head contact the lens.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) When the grinding head comes into contact with the lens, the grinding head rotates with the adapter rod as the fulcrum. The tilted grinding head can adapt to lenses of different sizes. It can grind the convex surface of the lens as well as the flat surface of the lens.

[0014] (2) When the grinding head is tilted, the spring pushes the fixing cap through the slide rod. The fixing cap makes the grinding head fit the lens perfectly, ensuring that the lens will not be ground incompletely.

[0015] (3) Tighten the top cap to move it down, and the adapter pipe can be moved down. At this time, pull the locking rod to separate it from the locking hole of the grinding head, and the grinding head can be taken out from the fixing cap for easy replacement of the grinding head.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figure 1-4 This utility model provides a technical solution: an adaptive lens grinding mechanism, including a drive head 1, the drive head 1 is Y-shaped, and two fixing caps 4 are rotatably installed at the lower end of the drive head 1. A lifting locking device is installed on the upper surface of the fixing caps 4. The Y-shaped arrangement has space inside to accommodate the grinding head 5 and the fixing caps 4, and will not obstruct the tilting of the fixing caps 4.

[0024] The housing 9 is provided in two and installed on the upper surface of the fixing cap 4. A locking rod 7 is inserted into the housing 9. The locking rod 7 is connected to the lifting locking device and passes through the housing 9. The lifting locking device can restrict the movement of the locking rod 7 and keep the locking rod 7 locked to the grinding head 5.

[0025] The tensioner is rotatably connected to the drive head 1 and the housing 9 at its upper and lower ends. The tensioner controls the balance of the fixed cap 4 and applies pressure to the grinding head 5 to ensure stable contact between the grinding head 5 and the lens, resulting in better grinding effect.

[0026] In this embodiment, as Figure 1 As shown, the drive head 1 is rotatably connected to the adapter rod 3, which is fixedly connected to the fixed cap 4. The adapter rod 3 provides a support point for the rotation of the fixed cap 4, so that the rotation of the fixed cap 4 will not come into contact with the drive head 1.

[0027] In this embodiment, as Figure 2 As shown, a grinding head 5 is installed in the fixed cap 4. The side of the grinding head 5 is provided with a locking hole 8 corresponding to the locking rod 7. When the grinding head 5 is placed in the drive head 1, the locking rod 7 moves and inserts into the locking hole 8, which can ensure that the grinding head 5 will not separate from the fixed cap 4, and the grinding head 5 is more stable when rotating.

[0028] In this embodiment, as Figure 2As shown, the lifting locking device includes a stud 11, a tightening cap 12 screwed onto the stud 11, and an adapter tube 10 sleeved on the stud 11. A push-pull rod 13 is rotatably connected between the adapter tube 10 and the locking rod 7. The tightening cap 12 can restrict the movement of the adapter tube 10. When the adapter tube 10 limits the locking rod 7 through the push-pull rod 13, it ensures that the locking rod 7 will not separate from the locking hole 8, thus maintaining the stability of the grinding head 5 installation.

[0029] In this embodiment, as Figure 1 and Figure 3 As shown, the tensioner includes a sleeve 2 and a slide rod 6 inserted into the sleeve 2. A spring 14 is connected between the slide rod 6 and the sleeve 2. A fixing head 15 is screwed to the upper end of the sleeve 2. The fixing head 15 is fixedly connected to the upper end of the spring 14. The upper end of the fixing head 15 is rotatably connected to the drive head 1. The spring 14 fixes the slide rod 6 to ensure that the slide rod 6 will not loosen, so that the spring 14 can maintain the position of the grinding head 5.

[0030] Specifically, in use, when the drive head 1 is connected to the drive motor, the drive head 1 rotates and drives the fixed cap 4 and the grinding head 5 to rotate through the adapter rod 3. The drive motor, in conjunction with the robotic arm, can be flexibly adjusted.

[0031] like Figure 4 As shown, the lens is positioned below the grinding head 5. When the grinding head 5 presses down on the lens, the top fixing cap 4 of the grinding head 5 rotates upward and tilts with the adapter rod 3 as the fulcrum. The top sliding rod 6 of the fixing cap 4 moves in the sleeve 2 and compresses the spring 14. The elastic force of the spring 14 pushes the sliding rod 6 back to apply pressure to the fixing cap 4. The fixing cap 4 ensures that the grinding head 5 is in stable contact with the lens, ensuring the grinding effect and ensuring that the grinding head 5 is always in contact with the lens. When the grinding head 5 contacts various positions of the lens, the fixing cap 4 automatically adjusts its position by rotation, which is suitable for grinding lenses of various sizes.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
