Description

Technical Field

[0001] This utility model relates to the field of lens edge grinding technology, and in particular to an edge grinding mechanism for lens processing. Background Technology

[0002] During the lens manufacturing process, not only is high-precision grinding and polishing required for the lens surface, but its edges also need to be ground. This is because high-precision lenses are typically used in precision instruments and equipment, and it is essential to ensure the lens's mounting performance. Precise edge grinding allows for more precise mounting, ensuring a tight fit and preventing light leakage during installation.

[0003] In the prior art, such as Chinese Patent No. CN221849654U, a processing table is included. The top of the processing table has an opening, and uprights are fixedly installed on both sides of the opening on the top of the processing table. A hydraulic cylinder is fixedly installed on the outer side of the left upright. The hydraulic cylinder pushes the left fixed seat to the right, so that the two fixed seats clamp and fix the lens. A drive motor rotates the drive wheel, which drives the driven wheel and the rotating shaft to rotate through the synchronous belt, further causing the right fixed seat to rotate, thereby driving the lens to rotate. The edge of the lens can be ground by the edge grinding component. The debris generated by edge grinding will fall into the housing through the opening. The exhaust fan sucks it out through the air outlet, so that the debris can be filtered into the housing through the filter screen on the filter frame. This structure can grind the lens and suck up debris and dust at the same time, which can reduce environmental pollution, facilitate maintenance, and has high practicality.

[0004] While the above solution has the advantages mentioned above, its disadvantages are that the lens needs to be manually positioned before it can be clamped, which affects work efficiency. In addition, the fixed distance between the edge grinding component and the clamping axis makes it impossible to process lenses of different sizes, thus reducing its applicability. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art where lens installation requires manual positioning and the processing dimensions cannot be changed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lens processing edge grinding mechanism, comprising a grinding box, and the lens processing edge grinding mechanism further comprising:

[0007] The electric actuator is fixedly installed on the top of the grinding box;

The elastic pull rod is rotatably installed on the fixed plate and has an inclined surface on one side. The positioning rod is fixedly installed on one end of the elastic pull rod.

[0010] The positioning mechanism can switch between a positioning state and a disengagement state. When in the positioning state, the positioning rods on both sides can clamp the lens towards the center for positioning. When in the disengagement state, the positioning rods can rotate to both sides.

[0011] The adjustment mechanism is installed on one side of the grinding box, and a sliding insert is embedded on it. The size of the lens processing can be adjusted by adjusting the position of the insert.

[0012] In a preferred embodiment, the positioning mechanism further includes:

[0013] The flexible telescopic rod is rotatably mounted on the top of the dust cover;

[0016] In a preferred embodiment, the lens processing edge grinding mechanism further includes:

[0017] The motor is fixedly installed at the bottom of the grinding box and located inside the dust cover;

[0018] The output end of the motor is fixedly connected to the bottom of the elastic telescopic rod.

[0019] The technical effect of adopting the above-mentioned further solution is that the motor installed inside the dust cover will not be affected by the dust generated during edge grinding.

[0020] In a preferred embodiment, the adjusting mechanism includes:

[0021] The pull box is slidably embedded in one side of the polishing box, and its surface has multiple slots.

[0022] The push block is slidably embedded inside the pull box.

[0024] In a preferred embodiment, the adjusting mechanism further includes:

[0025] Spring 2 has one end fixedly connected to the push block and the other end fixedly connected to the pull box;

[0026] The adjustable slider is slidably embedded in the pull box, and one end has a long groove and a short groove.

[0027] The technical effect of adopting the above-mentioned further solution is that the second spring can make the push block push the adjustable slider and maintain the thrust.

[0028] In a preferred embodiment, the adjusting mechanism further includes:

[0029] A fixed push rod is fixedly installed on one side of a fixed rod, with one end fitting into the short groove of the adjustable slider;

[0030] The grinding plate is fixedly installed on one side of the adjustable slider.

[0034] Two fixed rotating plates are rotatably mounted on one side of the grinding box.

[0035] The technical effect of adopting the above-mentioned further solution is that the fixed slider can restrict the movement of the fixed rotating plate after the fixed rotating plate fixes the box.

[0036] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0037] 1. This utility model allows for easy lens installation by simply extending the positioning rod to both sides and inserting the lens. The positioning rod then moves from both sides towards the center under the action of the elastic pull rod, positioning the lens. Subsequently, the electric push rod is activated to move the elastic telescopic rod, causing the positioning rod to rotate to both sides, thus preventing friction on the positioning rod during grinding. This solution utilizes the rebound of the elastic telescopic rod to quickly position the lens, reducing the positioning time required.

[0038] 2. This utility model involves compressing the spring by pressing the adjusting slider, then inserting the insert block into the slot. The insert block restricts the movement of the push block, thereby changing the distance the adjusting slider moves and adjusting the contact position between the grinding plate and the lens, thus changing the lens grinding dimensions. This solution adjusts the movement distance of the adjusting slider by the insertion position of the insert block, thereby changing the processing dimensions during lens processing and increasing the applicability of the device.

[0046] 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.

[0047] Example 1:

[0048] Please see Figures 1-3 This embodiment provides a lens processing edge grinding mechanism that can quickly position the lens. The specific idea is as follows: A lens processing edge grinding mechanism includes a grinding box 1. The lens processing edge grinding mechanism also includes an electric push rod 11, a dust cover 12, a motor 13 and a positioning mechanism.

[0049] It should be noted that users can install a nozzle inside the grinding box 1 and open a drainage hole according to their actual needs.

[0050] In order to ensure the stability of the clamping force, the electric push rod 11 is fixedly installed on the top of the grinding box 1.

[0051] It should be noted that, in order to avoid scratching the lens surface, a rubber ring should be installed at the bottom of the electric actuator 11 to prevent direct contact with the lens.

[0052] In addition, in order to prevent the motor 13 from being affected by dust, a dust cover 12 is installed, and the dust cover 12 is fixedly installed at the bottom of the grinding box 1.

[0053] The motor 13 is fixedly installed at the bottom of the grinding box 1 and is located inside the dust cover 12.

[0054] In addition, the output end of the motor 13 is fixedly connected to the bottom of the elastic telescopic rod 2.

[0055] The positioning mechanism is installed inside the grinding box 1. It includes a fixed rod 3, an elastic pull rod 32 and a positioning rod 33. The fixed rod 3 is fixedly installed on the top of the dust cover 12 and has a bevel block installed on one side. The top is slidably fitted with a fixed plate 31. The elastic pull rod 32 is rotatably installed on the fixed plate 31 and has a bevel on one side. The positioning rod 33 is fixedly installed on one end of the elastic pull rod 32.

[0056] In addition, the positioning mechanism can switch between a positioning state and a disengaged state. When in the positioning state, the positioning rods 33 on both sides can clamp the lens towards the center for positioning. When in the disengaged state, the positioning rods 33 can rotate to both sides.

[0057] In this embodiment, the positioning mechanism can be of various types, and this application does not limit its application. As an example of an optional solution, the specific arrangement of each component is as follows:

[0058] As one specific implementation, the positioning mechanism includes: an elastic telescopic rod 2, an elastic pin 21, a fixed rod 3, a fixed plate 31, an elastic pull rod 32, and a positioning rod 33.

[0059] The elastic telescopic rod 2 is rotatably mounted on the top of the dust cover 12.

[0060] It should be noted that, to avoid friction caused by direct contact between the elastic telescopic rod 2 and the fixed plate 31, ball bearings can be installed between them. Furthermore, to prevent scratching the lens surface, a rubber ring should be installed at the top of the elastic telescopic rod 2 to prevent direct contact with the lens.

[0061] In addition, to prevent the fixed plate 31 from sliding, the elastic pin 21 is slidably embedded in the elastic telescopic rod 2, and a spring is provided between the pin and the elastic telescopic rod 2.

[0062] In this embodiment, the positioning rod 33 is first stretched to both sides, and then the lens to be polished is placed on top of the elastic telescopic rod 2. The positioning rod 33 is then released, and it moves towards the center under the action of the elastic pull rod 32 to position the lens. After the electric push rod 11 is started, it first contacts the lens and then presses down the elastic telescopic rod 2, causing the elastic pin 21 to be pressed into the elastic telescopic rod 2. As the elastic telescopic rod 2 descends, the fixing plate 31 is pressed down, and the position where the elastic pull rod 32 contacts the inclined block on the fixing rod 3 begins to rotate, causing the positioning rod 33 to rotate to both sides and separate from the lens. After the motor 13 is started, it drives the elastic telescopic rod 2 to rotate and also drives the lens to be processed. At this time, since the fixing plate 31 slides on the fixing rod 3, it will not rotate with it. By setting ball bearings, the friction caused by the rotation of the elastic telescopic rod 2 on the fixing plate 31 can be reduced.

[0063] Example 2:

[0064] like Figures 1-5 As shown in the figure, based on embodiment 1, this embodiment also provides a lens processing edge grinding mechanism that can change the processing size. The specific idea is as follows: A lens processing edge grinding mechanism, which further includes: a distance adjustment mechanism.

[0065] The distance adjustment mechanism is installed on one side of the grinding box 1, and a block 41 is slidably embedded on it. The size of the lens processing can be adjusted by adjusting the position of the block 41.

[0066] In this embodiment, the specific type of the adjusting mechanism can be varied, and this application does not limit it. As an example of an optional solution, the specific arrangement of each component is as follows:

[0067] As one specific implementation, the distance adjustment mechanism includes: a pull box 4, an insert block 41, a second spring 42, a push block 43, a distance adjustment slider 44, a fixed push rod 45, a grinding plate 46, a fixed slider 47, and a fixed rotating plate 48.

[0068] The pull box 4 is slidably embedded on one side of the polishing box 1, and its surface has multiple slots.

[0069] In addition, the push block 43 is slidably embedded in the pull box 4.

[0070] Among them, one end of spring 42 is fixedly connected to push block 43, and the other end is fixedly connected to pull box 4.

[0071] In addition, the adjustable slider 44 is slidably embedded in the pull box 4, and one end is provided with a long groove and a short groove.

[0072] The fixed push rod 45 is fixedly installed on one side of the fixed rod 3, and one end is attached to the short groove of the adjustable slider 44.

[0073] In addition, the grinding plate 46 is fixedly installed on one side of the adjustable slider 44.

[0074] In order to prevent the fixed rotating plate 48 from sliding, a fixed slider 47 is provided, and the fixed slider 47 is slidably connected to the pull box 4.

[0075] In addition, to prevent the pull box 4 from falling off, both fixed rotating plates 48 are rotatably installed on one side of the grinding box 1.

[0076] In this embodiment, after the lens is positioned, the adjustment slider 44 can be manually pressed to compress the spring 42. Then, according to the processing requirements, the insert block 41 is inserted into the insertion hole on the pull box 4. Then, the adjustment slider 44 is released, the spring 42 rebounds, and the push block 43 and the adjustment slider 44 are pushed. Then, the pull box 4 is inserted into the grinding box 1. When inserted, the fixed push rod 45 will contact the short groove on the adjustment slider 44 to prevent the adjustment slider 44 from moving forward and to prevent the grinding plate 46 from contacting the lens. After the pull box 4 is inserted, the fixed rotating plates 48 on both sides are rotated and the fixed slider 47 is slid so that the fixed slider 47 fixes the fixed rotating plate 48 to prevent the pull box 4 from being ejected by the spring 42 due to the obstruction of the fixed push rod 45. After the installation of the pull box 4 is completed, the electric push rod 11 is activated, causing the elastic telescopic rod 2 to press down the fixing plate 31. As the fixing plate 31 descends, the fixing push rod 45 slides into the long groove of the adjusting slider 44. The adjusting slider 44 is pushed out by the action of the second spring 42 and the push block 43. At the same time, when the push block 43 is pushed out, it comes into contact with the insertion block 41 and cannot move forward. At this time, the distance between the grinding plate 46 and the center of the lens is the distance to be processed. If the grinding plate 46 comes into contact with the lens before the push block 43 contacts the insertion block 41, the lens will be unable to move under the clamping of the electric push rod 11 and the elastic telescopic rod 2. During the grinding process, the diameter of the lens will decrease. As the diameter of the lens decreases, the second spring 42 pushes the push block 43 to move until the push block 43 contacts the insertion block 41.

[0077] Working principle: After opening the grinding box 1, pull the positioning rod 33 to both sides, then place the lens to be ground on the top of the elastic telescopic rod 2, and then release the positioning rod 33. Under the pulling force of the elastic pull rod 32, the positioning rod 33 moves towards the center, and the lens is positioned by the force of the positioning rod 33 moving towards the center. After positioning is completed, press and hold the distance adjustment slider 44 to compress the spring 42 of the push block 43. Then, according to the size to be polished, insert the insert block 41 into the slot on the pull box 4. Release the distance adjustment slider 44. At this time, the spring 42 will push out the push block 43 and the distance adjustment slider 44. When the push block 43 is pushed out, it is blocked by the insert block 41 and can only reach the predetermined distance. Then, insert the pull box 4 into the polishing box 1 and rotate the two fixed rotating plates 48 to block the movement of the pull box 4. Slide the fixed slider 47 to insert it into the fixed rotating plate 48 and fix the position of the fixed rotating plate 48. At this time, the fixed push rod 45 on the fixed plate 31 will contact the short groove on the distance adjustment slider 44 and compress the spring 42 of the distance adjustment slider 44 to prevent the polishing plate 46 from touching the lens and affecting the positioning of the lens. Then, the electric push rod 11 is activated, causing it and the elastic telescopic rod 2 to clamp the lens and move the elastic telescopic rod 2 downwards. As the elastic telescopic rod 2 moves, the elastic pin 21, which originally provided support for the fixed plate 31, slides inwards. Simultaneously, as the elastic telescopic rod 2 descends, the fixed plate 31 also descends. The inclined surface on the elastic pull rod 32 contacts the inclined block on the fixed rod 3, ensuring that the fixed plate 31 descends while rotating to both sides. In addition, as the fixed plate 31 moves, the fixed push rod 45 moves accordingly and slides into the long groove. At this time, the push block 43 is ejected under the action of the spring 42 and pushes the adjustment slider 44 to move, so that the surface of the grinding plate 46 is in contact with the lens. At this point, starting the motor 13 can achieve edge grinding of the lens.
