[0003] However, the device has certain shortcomings in use. It is not easy to adjust and control the protective clamping and fixing of lenses of different thicknesses, which makes the lenses easy to break. At the same time, the device lacks limiting after clamping and fixing the lens, which causes the lens to loosen during the processing. Utility Model Content
[0004] The purpose of this invention is to provide a turning fixture for optical lenses, which solves the problems of the device being inconvenient to adjust and control for protective clamping and fixing of lenses of different thicknesses, which leads to easy breakage of the lenses. At the same time, the device lacks limiting positions after clamping and fixing the lenses, which causes the lenses to loosen during processing.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a turning fixture for optical lenses, including a support, a clamping mechanism on the support, a turntable on the clamping mechanism, a limiting mechanism on the support, a bracket fixedly connected to the end of the support, a motor fixedly mounted on the surface of the bracket, the motor's shaft passing through the bracket and rotatably connected to the bracket, a clamping plate on the clamping mechanism, and an anti-slip pad on the clamping plate.
[0006] Preferably, the clamping mechanism includes a slide cylinder, which is mounted inside the support via bearings. A support shaft is slidably connected inside the slide cylinder, and the support shaft is fixedly connected to a clamping plate. A sliding plate is slidably connected inside the support, and a bidirectional screw is rotatably connected inside the support. The bidirectional screw and the sliding plate are threaded together, and the bidirectional screw is fixedly connected to a turntable. A support sleeve is fixedly connected to the end of the sliding plate, and the support sleeve and the support shaft are connected via bearings. By rotating the bidirectional screw and the sliding plate to perform threaded movement, the support shaft moves, which in turn moves the two turntables. This allows for the clamping and fixing of lenses of different thicknesses, and the anti-slip pads protect the lenses, preventing excessive clamping force from causing lens breakage.
[0007] Preferably, a sliding pin is fixedly connected to the surface of the support shaft, and the sliding pin is slidably connected to the slide cylinder. By providing the sliding pin, rotation of the support shaft relative to the slide cylinder is prevented.
[0008] Preferably, a limiting plate is fixedly connected to the surface of the support, and the limiting plate is rotatably connected to the bidirectional screw. The limiting plate prevents the bidirectional screw from moving out of control.
[0009] Preferably, the limiting mechanism includes a support plate, with the support plate fixedly connected to the surface of the support. A connecting rod is movably connected inside the support plate, and a support block is mounted on the outer side of the connecting rod via a bearing. A locking rod is fixedly connected inside the support block, and the locking rod is slidably connected to the turntable. A spring is provided on the outer side of the connecting rod, and a locking block is fixedly connected to the outer side of the connecting rod. The spring acts on the support block, causing the locking rod to enter the locking groove of the turntable, thus facilitating the limiting of the turntable. This makes the device more stable when clamping the lens, preventing the lens from loosening during machining.
[0010] Preferably, a dovetail block is fixedly connected to the end of the locking rod, and the dovetail block is slidably connected to the support. By setting the dovetail block, the movement of the locking rod is made stable.
[0011] Preferably, one end of the spring is fixedly connected to the support plate, and the other end of the spring is fixedly connected to the support block. By providing the spring, the support block can be easily reset.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model uses the rotation of a bidirectional screw and a sliding plate to make a spiral motion, which in turn moves the support shaft and the two turntables. It can clamp and fix lenses of different thicknesses, and the anti-slip pads protect the lenses and prevent excessive clamping force from causing them to break.
[0014] 2. This utility model uses a spring to act on the support block, causing the clamping rod to enter the slot of the turntable, which makes the turntable easier to limit the position, and makes the device more stable after clamping the lens, thus preventing the lens from loosening during the turning process.

[0020] 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.
[0021] Please see Figures 1-2 A turning fixture for optical lenses includes a support 1, a clamping mechanism 2 on the support 1, a turntable 3 on the clamping mechanism 2, a limit mechanism 4 on the support 1, a bracket 5 fixedly connected to the end of the support 1, a motor 6 fixedly mounted on the surface of the bracket 5, the rotating shaft of the motor 6 passing through the bracket 5 and rotatably connected to the bracket 5, a clamping plate 7 on the clamping mechanism 2, and an anti-slip pad 8 on the clamping plate 7.
[0022] Please see Figure 1 , Figure 3The clamping mechanism 2 includes a slide cylinder 21. The slide cylinder 21 is mounted inside the support 1 via bearings. A support shaft 22 is slidably connected inside the slide cylinder 21. The support shaft 22 is fixedly connected to the clamping plate 7. A sliding pin 23 is fixedly connected to the surface of the support shaft 22, and the sliding pin 23 is slidably connected to the slide cylinder 21. By setting the sliding pin 23, the support shaft 22 is prevented from rotating relative to the slide cylinder 21. A sliding plate 24 is slidably connected inside the support 1. A double-acting screw 25 is rotatably connected inside the support 1. The double-acting screw 25 and the sliding plate 24 are connected by threads. The double-acting screw 25 is fixedly connected to the turntable 3. Next, a limiting plate 26 is fixedly connected to the surface of the support 1. The limiting plate 26 and the bidirectional screw 25 are rotatably connected. By setting the limiting plate 26, the bidirectional screw 25 is prevented from moving. A support sleeve 27 is fixedly connected to the end of the slide plate 24. The support sleeve 27 and the support shaft 22 are connected by a bearing. By rotating the bidirectional screw 25 and the slide plate 24 to make threaded movement, the support shaft 22 moves, which in turn moves the two turntables 3. Lenses of different thicknesses can be clamped and fixed. The anti-slip pad 8 protects the lens and prevents the lens from being damaged due to excessive clamping force.
[0023] Please see Figure 1 , Figure 2 , Figure 4 The limiting mechanism 4 includes a support plate 41. The support plate 41 is fixedly connected to the surface of the support 1. A connecting rod 42 is movably connected inside the support plate 41. A support block 43 is installed on the outside of the connecting rod 42 through a bearing. A locking rod 44 is fixedly connected inside the support block 43. The locking rod 44 is slidably connected to the turntable 3. A dovetail block 45 is fixedly connected to the end of the locking rod 44. The dovetail block 45 is slidably connected to the support 1. By setting the dovetail block 45, the locking rod 44 can move stably. A spring 46 is set on the outside of the connecting rod 42. One end of the spring 46 is fixedly connected to the support plate 41, and the other end of the spring 46 is fixedly connected to the support block 43. By setting the spring 46, the support block 43 can be easily reset. A locking block 47 is fixedly connected to the outside of the connecting rod 42. The spring 46 acts on the support block 43, causing the locking rod 44 to enter the locking groove of the turntable 3, thereby making the turntable 3 easy to limit. This makes the device more stable after clamping the lens and prevents the lens from loosening during the turning process.
[0024] The specific implementation process of this utility model is as follows: In use, manually move the connecting rod 42 upward, causing the support block 43 to move upward. The support block 43 drives the locking rod 44 upward, causing the locking rod 44 to disengage from the locking groove on the turntable 3. The upward movement of the support block 43 compresses the spring 46. At the same time, the locking block 47 passes through the support plate 41. Then rotate the connecting rod 42, causing the locking block 47 to rotate 90 degrees, thus limiting the connecting rod 42. Then place the lens between the two clamping plates 7. Manually rotate the turntable 3, causing the turntable 3 to drive the bidirectional screw 25 to rotate. The bidirectional screw 25 rotates and makes a threaded movement with the slide plate 24, thereby causing the slide plate 24 to drive the support sleeve 27 to move. The support sleeve 27 drives the support shaft 22 to move. The support shaft 22 drives the clamping plate 7 to move. The movement of the clamping plate 7 drives the anti-slip pad 8 to move. The anti-slip pad 8 contacts the lens to clamp and fix it. By rotating the bidirectional screw 25 and the slide plate 24, the support shaft 22 moves, which in turn moves the two turntables 3. This allows for clamping and fixing lenses of different thicknesses. The anti-slip pad 8 protects the lens and prevents it from breaking due to excessive clamping force. Then, the connecting rod 42 is rotated 90 degrees, and the spring 46 resets, causing the support block 43 to reset. The reset of the support block 43 causes the locking rod 44 to reset and enter the slot of the turntable 3, limiting the turntable 3. The spring 46 acts on the support block 43, causing the locking rod 44 to enter the slot of the turntable 3, making the turntable 3 easier to limit. This makes the device more stable after clamping the lens and prevents the lens from loosening during turning.
