Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, specifically to an optical lens edge chamfering and grinding device. Background Technology

[0002] In the manufacturing process of optical imaging systems, precision optical instruments, and consumer electronics optical components, edge chamfering and grinding of optical lenses is an indispensable key process. Edge chamfering can not only effectively eliminate sharp edges of the lens, preventing problems such as chipping and breakage during assembly and use, but also reduce stress concentration on the lens surface, thereby improving the stability and reliability of the optical system.

[0003] However, most optical lens edge chamfering grinding devices on the market use a single-sided sequential processing method, that is, first chamfering and grinding one surface edge of the lens, and then flipping the lens over to process the other edge, which consumes a lot of time and results in low production efficiency. In order to solve the above problems, the inventor proposes an optical lens edge chamfering grinding device. Utility Model Content

[0004] In order to solve the problem of low efficiency of optical lens edge chamfering grinding device, the purpose of this utility model is to provide an optical lens edge chamfering grinding device.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: an optical lens edge chamfering grinding device, comprising a processing platform, a placement table rotatably connected to the top center of the processing platform, a lens body placed on the top of the placement table, two symmetrically distributed positioning components arranged on both sides of the top of the processing platform and on both sides of the lens body, the positioning components being used for positioning and clamping the lens body, a grinding component arranged on the top side of the positioning component near the lens body, the grinding component being used for chamfering grinding of the lens body, the grinding component and the positioning component being perpendicularly distributed, an L-shaped plate fixedly connected to the top side of the processing platform opposite to the grinding component, a hydraulic cylinder fixedly installed on the top of the L-shaped plate, a pressure plate rotatably connected to the piston rod of the hydraulic cylinder, the bottom end of the pressure plate abutting against the placement table, a motor four fixedly installed on the top side of the processing platform near the placement table, a gear one fixedly connected to the drive end of the motor four, a gear two fixedly connected to the outer side of the placement table's rotating shaft, the gear one and gear two being meshed.

[0006] Preferably, the positioning component includes a mounting groove 1, which is located at the top of the processing platform. A bidirectional lead screw is rotatably connected inside the mounting groove 1. Two symmetrically distributed movable seats are threaded to the outer side of the bidirectional lead screw. A clamping plate is fixedly connected to the opposite side of the top of each movable seat. Rotating rollers are rotatably connected to both ends of each clamping plate. A motor 1 is fixedly installed on one side of the processing platform. The drive end of the motor 1 is fixedly connected to the bidirectional lead screw.

[0007] Preferably, the grinding assembly includes a second mounting slot, which is located at the top of the processing platform. A threaded rod is rotatably connected inside the second mounting slot, and a movable frame is threadedly connected to the outer side of the threaded rod. A second motor is fixedly mounted on one side of the processing platform, and the drive end of the second motor is fixedly connected to the threaded rod. A slide plate is slidably engaged on one side of the movable frame, and a threaded column is rotatably connected to the side of the slide plate away from the movable frame. A slider is threadedly connected to the outer side of the threaded column, and the slider is slidably connected to the slide plate.

An electric push rod is fixedly mounted on one side of the movable frame, and the piston rod of the electric push rod is fixedly connected to the push plate.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. By placing two grinding plates on the upper and lower sides of the optical lens, the two sides of the optical lens can be chamfered simultaneously when the optical lens rotates, avoiding the method of processing one side at a time, thus further improving the chamfering efficiency of the optical lens. At the same time, the motor drives the threaded column to rotate, and the slider moves linearly along the outside of the threaded column, thereby driving the cross rod to rotate crosswise, adjusting the angle between the two grinding plates and the horizontal plane, realizing the adjustment of the chamfering angle, and further improving the applicability of the equipment.

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.

[0018] Example: Figure 1-4As shown, this utility model provides an optical lens edge chamfering grinding device, including a processing platform 1, a placement table 2 rotatably connected to the top center of the processing platform 1, a lens body 11 placed on the top of the placement table 2, two symmetrically distributed positioning components 3 are provided on the top of the processing platform 1 and on both sides of the lens body 11, the positioning components 3 are used to position and clamp the lens body 11, and a grinding component 4 is provided on the top of the positioning component 3 near the lens body 11, the grinding component 4 is used to chamfer the lens body 11, and the grinding component 4 is perpendicular to the positioning component 3.

[0019] The positioning component 3 includes a mounting groove 31, which is located at the top of the processing platform 1. A bidirectional lead screw 32 is rotatably connected inside the mounting groove 31. Two symmetrically distributed movable seats 33 are threaded to the outer side of the bidirectional lead screw 32. A clamping plate 34 is fixedly connected to the opposite side of the top of each movable seat 33. Rotating rollers 35 are rotatably connected to both ends of the clamping plate 34. A motor 36 is fixedly installed on one side of the processing platform 1. The drive end of the motor 36 is fixedly connected to the bidirectional lead screw 32.

[0020] By adopting the above technical solution, the motor 36 drives the bidirectional lead screw 32 to rotate, which in turn drives the two sets of moving seats 33, clamping plates 34 and rotating rollers 35 to move symmetrically towards or away from the lens body 11. The rotating rollers 35 are used to position the lens body 11 so that the central axis of the lens body 11 is in the same straight line as the central axis of the placement platform 2. At the same time, the rotating rollers 35 are set so that the lens body 11 can still rotate while being restricted and limited.

[0021] The grinding assembly 4 includes a second mounting slot 41, which is located at the top of the processing platform 1. A threaded rod 42 is rotatably connected inside the second mounting slot 41, and a movable frame 43 is threadedly connected to the outside of the threaded rod 42. A second motor 44 is fixedly installed on one side of the processing platform 1, and the drive end of the second motor 44 is fixedly connected to the threaded rod 42.

[0022] By adopting the above technical solution, the threaded rod 42 is rotated by the motor 44, and the moving frame 43 moves linearly along the outside of the threaded rod 42 relative to the lens body 11, thereby adjusting the distance between the chamfering device and the lens body 11.

[0023] A sliding plate 45 is slidably engaged on one side of the movable frame 43. A threaded post 46 is rotatably connected to the side of the sliding plate 45 away from the movable frame 43. A slider 48 is threadedly connected to the outer side of the threaded post 46. The slider 48 is slidably connected to the sliding plate 45. A cross rod 49 is rotatably connected between one side of the slider 48 and the sliding plate 45. Two grinding plates 410 are fixedly connected to the front end of the cross rod 49. A motor 47 is fixedly installed on the top of the sliding plate 45. The drive end of the motor 47 is fixedly connected to the threaded post 46.

[0024] By adopting the above technical solution, the motor 47 drives the threaded column 46 to rotate, and at the same time drives the slider 48 to move linearly along the outside of the threaded column 46, thereby driving the cross rod 49 to rotate crosswise, adjusting the angle between the two grinding plates 410 and the horizontal plane, and realizing the adjustment operation of the chamfer angle.

[0025] The top of the movable frame 43 is provided with an active groove 411. A push plate 412 is fixedly connected to the side of the slide plate 45 away from the slider 48. An electric push rod 413 is fixedly installed on one side of the movable frame 43. The piston rod of the electric push rod 413 is fixedly connected to the push plate 412.

[0026] By adopting the above technical solution, the extension and retraction of the piston rod of the electric push rod 413 pushes the push plate 412 to move vertically along the interior of the movable groove 411, thereby adjusting the height of the grinding plate 410 and realizing the chamfering operation of optical lenses of different thicknesses.

[0027] An L-shaped plate 5 is fixedly connected to the top of the processing platform 1 on the side opposite to the grinding assembly 4. A hydraulic cylinder 6 is fixedly installed on the top of the L-shaped plate 5. The piston rod of the hydraulic cylinder 6 is rotatably connected to a pressure plate 7. The bottom end of the pressure plate 7 abuts against the placement table 2.

[0028] By adopting the above technical solution, the extension and retraction of the piston rod of the hydraulic cylinder 6 pushes the pressure plate 7 to move vertically, and the pressure plate 7 clamps and fixes the lens body 11. The pressure plate 7 is rotatably connected to the piston rod of the hydraulic cylinder 6, so that the lens body 11 can still rotate while being clamped and fixed.

[0029] A motor 4 8 is fixedly installed on the top of the processing platform 1 near the side of the placement table 2. A gear 1 9 is fixedly connected to the drive end of the motor 4 8. A gear 2 10 is fixedly connected to the outside of the rotating shaft of the placement table 2. Gear 1 9 and gear 2 10 are meshed together.

[0030] By adopting the above technical solution, the motor 8 drives the gear 9 to rotate, and the gear 9 meshes with the gear 10, which in turn drives the placement platform 2 to rotate, thereby driving the lens body 11 to rotate, thus realizing the chamfering operation around the lens body 11.

[0031] Working principle: When chamfering the edge of a circular optical lens, the lens body 11 is placed on the top of the placement stage 2. Then, the motor 36 drives the bidirectional lead screw 32 to rotate, which in turn drives the two sets of moving seats 33, clamping plates 34 and rotating rollers 35 to move symmetrically towards or away from the lens body 11. The rotating rollers 35 are used to position the lens body 11 so that the central axis of the lens body 11 is in the same straight line as the central axis of the placement stage 2. At the same time, the rotating rollers 35 are set so that the lens body 11 can still rotate while being restricted and limited.

[0032] Next, by extending and retracting the piston rod of the hydraulic cylinder 6, the pressure plate 7 is pushed to move vertically, and the pressure plate 7 is used to clamp and fix the lens body 11.

[0033] Then, motor 44 drives the threaded rod 42 to rotate, and at the same time drives the moving frame 43 to move linearly along the outside of the threaded rod 42 relative to the lens body 11, adjusting the distance between the chamfering device and the lens body 11. Motor 47 drives the threaded column 46 to rotate, and at the same time drives the slider 48 to move linearly along the outside of the threaded column 46, thereby driving the cross rod 49 to rotate crosswise, adjusting the angle between the two grinding plates 410 and the horizontal plane, realizing the adjustment of the chamfering angle. At the same time, through the extension and retraction of the piston rod of the electric push rod 413, the push plate 412 is pushed to move vertically along the inside of the movable groove 411, thereby adjusting the height of the grinding plates 410, so that the two grinding plates 410 are symmetrically placed above and below the lens body 11.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
