Description

Technical Field

[0001] The invention relates to the technical field of lens edge grinding devices, in particular to a grinding wheel device of a lens edge grinding machine. Background Art

[0002] Grinding wheel is also called bonded abrasive tool, which is a bonded abrasive tool with a certain strength and ordinary abrasives are bonded into a certain shape (mostly round with a through hole in the center) by a binder. During use, the grinding wheel is driven by the equipment to rotate at high speed, so that the grinding wheel can perform rough grinding, semi-finishing grinding and fine grinding, as well as grooving and cutting on the outer cylindrical surface, inner cylindrical surface, plane and various shaped surfaces of metal or non-metal workpieces.

[0003] After the production of optical lenses is completed, they are usually grinded by an edge grinder on the outer edge and chamfers of the lenses. When using the edge grinder in the prior art, a contact clamping device is required to fix the lens, and a grinding wheel is used for edge grinding. However, in this process, the clamping range of the clamping device and the distance from the grinding wheel need to be adjusted according to the thickness and radius of the lens. In addition, the lens is usually round, and a rotating structure is required to drive the lens to rotate for edge grinding. If the clamping assembly cannot ensure that the center position of the lens is in the same straight line as the rotating structure, the distance between the outer edge of the lens and the grinding wheel will be different during the rotation process, which will affect the grinding of the lens and the product quality. Therefore, it is necessary to manually correct and align the position of the lens before grinding, which takes a lot of time. Summary of the invention

When the two insertion racks 34 and the buckle plates 39 in the same inclined frame 31 move in opposite directions, the gap in the middle is expanded to facilitate the placement and removal of the lenses. When the two insertion racks 34 and the buckle plates 39 in the same inclined frame 31 move closer, it is convenient to adjust the radius of the lens body 4. The four groups of buckle plates 39 are respectively buckled on both sides of the top and bottom of the lens body 4, and they are limited so that the extrusion pad 29 and the center of the lens body 4 remain in the same straight line. The insertion rack 34 slides along the first movable groove 21 through the slide seat 37 to adjust the lateral position of the buckle plate 39. The slide seat 37 is not connected to the two-way screw 22.

[0032] In this embodiment, a first moving notch 15 is provided on the surface of the driving rod 13 at the axis of the second grinding wheel 14, and the second grinding wheel 14 is slidably engaged in the first moving notch 15. A shaft ring 141 is rotatably mounted on the outer side of the second grinding wheel 14 through a bearing, and the shaft ring 141 slides along the surface of the driving rod 13. A plug plate 38 is slidably inserted on the outer side of the slide seat 37, and one end of the plug plate 38 is fixed to the moving seat 24. Two groups of electromagnetic plug rods 310 in opposite directions are fixed to the outer side of the slide seat 37, and the lower end electromagnetic plug rods 310 on the side of the slide seat 37 can be pressed and contacted with the plug plate 38. A connecting frame 142 is fixed to the bottom of the shaft ring 141, and a plug hole is provided at the other end of the connecting frame 142 toward the top of the electromagnetic plug rod 310. The slide seat 37 The electromagnetic plunger 310 at the upper end of the side can be inserted into the connecting frame 142.

The connecting frames 142 are fixed to the outer sides of the shaft rings 141 of the two second grinding wheels 14, and the two connecting frames 142 are offset, that is, offset up and down, and do not interfere with each other during translation, and the other end of the connecting frame 142 is connected to the limit assembly 3 in the opposite direction. In simple terms, the initial positions of the two second grinding wheels 14 are set to X and Y respectively, and the initial positions of the limit assembly 3 corresponding to the straight line are set to Z and W respectively, X and Z are on a straight line, and Y and W are on a straight line. Here, the connecting frame 142 of X is connected to the electromagnetic plunger 310 of W, and the position of the second grinding wheel 14 of X is always the same as Z The position of the buckle plate 39 of Y is in a straight line. Similarly, the connecting frame 142 of Y is connected to the electromagnetic plug rod 310 of Z, and the position of the second grinding wheel 14 of Y is in a straight line with the position of the buckle plate 39 of W. Therefore, when the buckle plates 39 of the two sets of limit assemblies 3 are moved and adjusted, the corresponding second grinding wheel 14 will also be adjusted synchronously and always remain close to the buckle plate 39 to grind the edges of both sides of the lens. A locking bolt 143 is inserted on one side of the shaft ring 141 of the second grinding wheel 14, and the locking bolt 143 can be squeezed and contacted with the driving rod 13.

The connecting frame 142 is connected to the shaft ring 141 outside the second grinding wheel 14 and the other end is located at the electromagnetic plug rod 310. The top of the magnetic plug rod 310 will not cause movement interference to other structures on the bottom plate 2.

After the two groups of second grinding wheels 14 are inserted, the chamfers of the edge of the lens can be polished. After determining the position, the lens body 4 is placed in the space included by the buckle plates 39, and then the electromagnetic plug rod 310 at the upper end of the slide 37 is retracted.The electromagnetic plug rod 310 at the lower end extends out and squeezes on the plug plate 38 (in this process, a metal surface can be set on the plug plate 38, and a magnet block can be set at the extended end of the electromagnetic plug rod 310 at the lower end. The sliding seat 37 and the moving seat 24 are locked by the adsorption of the magnet block and the metal surface. The magnetic adsorption force will not separate without applying external force. When the extended end of the electromagnetic plug rod 310 is retracted, it can be separated from the plug plate 38). Then, when the moving seat 24 slides along the first moving groove 21, the plug frame 34 moves synchronously with the sliding seat 37, and the buckle plate 39 moves away from the lens body 4, releasing the limit on the lens body 4, and replacing The squeeze pad 29 is replaced to squeeze and fix the two sides of the lens, and after the pinch plate 39 is away from the lens, it is convenient for the lens to rotate and contact the first grinding wheel 12 and the second grinding wheel 14 for edge grinding. During the movement of the squeeze pad 29, the pinch plate 39 and the lens are separated and easily cause the lens to fall. The problem does not exist, because the movement of the squeeze pad 29 will drive the pinch plate 39 to move away from the lens. At this time, although the pinch plate 39 is away from the lens, the plug-in frame 34 connected to the pinch plate 39 still limits the lens, and the lens will not fall and will be kept inside the four plug-in frames 34. When the squeeze pad 29 contacts the lens, it is also exactly at the center of the lens.

[0033] When using the device, the lens body 4 is placed between the two groups of inclined frames 31. According to the thickness and radius of the lens body 4, the horizontal and vertical positions of the plug and the buckle plate 39 on the inclined frame 31 are adjusted. The electromagnetic plug rod 310 at the upper end of the slide seat 37 is inserted into the interior of the connecting frame 142. When the lens body 4 is placed, the first moving groove 21 is moved to adjust the position of the buckle plate 39. Through the connection of the connecting frame 142, the second grinding wheel 14 moves synchronously along the first moving notch 15. When adjusting the positions of the buckle plates 39 on both sides, the two groups of second grinding wheels are synchronously adjusted. 14, so that it is convenient for the pinch plate 39 to limit the top and bottom sides of the lens body 4 respectively, and at the same time, after inserting the two sets of second grinding wheels 14, the chamfer of the edge of the lens can be polished. After determining the position, the lens body 4 is placed in the space included by the pinch plate 39, and then the electromagnetic plug rod 310 at the upper end of the slide 37 is retracted, and the electromagnetic plug rod 310 at the lower end is extended to squeeze on the plug plate 38. Then, when the moving seat 24 slides along the first moving groove 21, the plug frame 34 moves synchronously with the slide 37, and the pinch plate 39 Move away from the lens body 4, release the limit on the lens body 4, replace the squeezing pad 29 to squeeze and fix the two sides of the lens, turn on the second motor 23 to drive the bidirectional screw 22 to rotate, the two moving seats 24 engage with the bidirectional screw 22 and slide along the first moving groove 21, at this time, the pulley at the lower end of the transmission belt 27 slides along the inside of the second moving notch 210, along with the moving seat 24, the connecting rod 28 and the squeezing pad 29 synchronously move until the two squeezing pads 29 are respectively squeezed and contacted with the center of the two sides of the lens body 4, then after the buckle plate 39 releases the limit on the lens body 4, the bottom plate 2 is moved to the position of the first grinding wheel 12 and the second grinding wheel 14, the third motor 26 drives the shaft 25 to rotate, through the transmission of the transmission belt 27, the two groups of connecting rods 28 and the squeezing pad 29 synchronously drive the lens body 4 to rotate, the edge of the lens body 4 is contacted with the first grinding wheel 12 and the second grinding wheel 14 for grinding, then the first motor 11 is turned on to drive the driving rod 13 to rotate, and the squeezing pad 29 drives the lens body 4 to rotate itself, and the edge of the lens is ground.
