Description

Technical Field

[0001] The present invention relates to the technical field of optical lens grinding. More specifically, the present invention relates to a rough grinding device for optical lens processing. Background Art

[0002] When an optical lens is produced and processed, a short cylindrical raw material is first obtained by a blanking mechanism, and then the short cylindrical raw material is ground by a grinding machine. When the outer circumferential surface of the short cylindrical raw material is roughly ground in the prior art, usually only one short cylindrical raw material can be ground at the same time. Even if a small number of grinding machines can grind multiple short cylindrical raw materials at the same time, the process of manually clamping multiple short cylindrical raw materials to the grinding machine is relatively complex and cumbersome, and it is difficult to ensure that each short cylindrical raw material is completely aligned. As a result, after the grinding machine synchronously grinds multiple short cylindrical raw materials, some short cylindrical raw materials will have incomplete grinding or over-grinding phenomena.

[0038] The working principle of the above embodiment is as follows:

[0039] When clamping the workpiece body 14, the operator places the three workpiece bodies 14 on the upper side of the two first round rods 10. At this time, the positions of the three workpiece bodies 14 are as Figure 2 shown. Then, the operator applies an upward thrust to the first connecting block 12. Under the guiding action of the connecting plate 8, when viewed from right to left, the first connecting block 12 rotates counterclockwise. The first connecting block 12 drives the two second round rods 11 to move until one of the second round rods 11 contacts the first magnet 13. The first magnet 13 attracts and tightens the second round rod 11 through magnetic force. At this time, the two second round rods 11 just move to the direct upper side of the workpiece body 14, that is, the two first round rods 10 and the two second round rods 11 are distributed around the three workpiece bodies 14. Through the cooperation of the two first round rods 10 and the two second round rods 11, the three workpiece bodies 14 are positioned simultaneously, so that the axes of the three workpiece bodies 14 are aligned with each other. Then, the second motor 205 is started. The second motor 205 drives the lead screw 206 to rotate. The lead screw 206 drives the rightmost slider 5 to move leftward. The slider 5 drives the ring 6 and the first fixing block 7 thereon to move leftward, so that the rightmost first fixing block 7 contacts the rightmost workpiece body 14. Then, the rightmost first fixing block 7 pushes the rightmost workpiece body 14 to move leftward, so that the rightmost workpiece body 14 contacts the second first fixing block 7 from right to left and pushes the second first fixing block 7 from right to left to move leftward, so that the second first fixing block 7 from right to left pushes the workpiece body 14 in the middle to move leftward, so that the workpiece body 14 in the middle contacts the third first fixing block 7 from right to left and pushes the third first fixing block 7 from right to left to move leftward, so that the third first fixing block 7 from right to left pushes the leftmost workpiece body 14 to the leftmost first fixing block 7, thereby clamping the three workpiece bodies 14 simultaneously through the cooperation of the four first fixing blocks 7 to complete the clamping operation. During this process, through the cooperation of the two first round rods 10 and the two second round rods 11, the three workpiece bodies 14 are limited, so as to avoid the offset phenomenon of the workpiece body 14 due to the clamping extrusion force.

[0040] After the clamping is completed, manually push the connecting block 12 and the round rod 11 back. When the round rod 11 moves back to its original position, continue to manually push the connecting block 12. The connecting block 12 drives the round rod 11 to move, causing the round rod 11 to drive the connecting plate 8 to move downward and compress the first spring 9. When the connecting plate 8 moves downward, its lower edge contacts the inclined surface of the second fixing block 209. As the connecting plate 8 continues to move downward, it will force the second fixing block 209 to move away from the side plate 3 and stretch the third spring 2010. When the through slot 91 on the side plate 3 is aligned with the second fixing block 209, the third spring 2010 rebounds and drives the second fixing block 209 to move, causing the second fixing block 209 to insert into the through slot 91. At this time, stop manually pushing the connecting block 12, and fix the connecting plate 8 through the second fixing block 209. During this process, the connecting plate 8 will also drive the first round rod 10 and the round rod 11 downward, causing the first round rod 10 and the round rod 11 to move downward away from the workpiece body 14. Then, the telescopic cylinder 101 drives the electric grinding roller 102 to move toward the workpiece body 14, making the electric grinding roller 102 contact the workpiece body 14. At the same time, start the first motor 201. The first motor 201 drives the column gear 202 to rotate. The column gear 202 drives the spur gear 203 to rotate. The spur gear 203 drives the toothed ring 204 to rotate. The toothed ring 204 drives the four first fixing blocks 7 to rotate synchronously. The four first fixing blocks 7 drive the three workpiece bodies 14 to rotate synchronously, so as to simultaneously grind the three workpiece bodies 14 through the electric grinding roller 102. During the clamping process, the horizontally moving slider 5 will compress the second spring 207. After the grinding is completed, turn off the electric grinding roller 102. The telescopic cylinder 101 drives the electric grinding roller 102 to move back to its original position. Turn off the first motor 201 to stop the first fixing block 7 from driving the workpiece body 14 to rotate. Then, the second motor 205 drives the lead screw 206 to rotate. The lead screw 206 drives the rightmost slider 5 to move back to its original position, causing the compressed second spring 207 to rebound and drive the middle two sliders 5 to reset, so that the first fixing block 7 stops clamping the workpiece body 14. Then, manually take out the ground workpiece body 14, and pull the second fixing block 209 again to pull the second fixing block 209 out of the through slot 91, so that the first spring 9 rebounds and drives the connecting plate 8 and the parts on it to move back to their original positions to complete the reset operation. When in use, the operator only needs to place the three workpiece bodies 14 on the two first round rods 10 and push the connecting block 12 up and down once to simultaneously complete the clamping operation of the three workpiece bodies 14. The operation is convenient, and the three workpiece bodies 14 will not shift during the clamping process, avoiding the problems of difficult operation and misalignment when clamping multiple workpiece bodies 14 in the prior art. During the process of pushing the connecting block 12 downward, the connecting block 12 can also control the first round rod 10 and the round rod 11 to move away from the workpiece body 14 to prevent the first round rod 10 and the round rod 11 from interfering with the grinding of the workpiece body 14, and this process can be achieved only by increasing the downward movement stroke of the connecting block 12 manually without additional control.Further reduce the difficulty of manual operation, which is beneficial to improving convenience.

[0041] It should be understood that during the sliding process of the slider 5 on the connecting frame 4, the slider 5 drives the parts thereon to move together, that is, the slider 5 drives the spur gear 203 to slide left and right on the rack gear 202, so that the spur gear 203 is always meshed with the rack gear 202.

[0042] According to the above working principle, we can know that the present invention has the following effects:

[0043] Manually only need to place the three workpiece bodies 14 on the two round rods 10, and then push the connecting block 12 up and down once, then the clamping operation of the three workpiece bodies 14 can be completed at the same time. The operation is convenient, and the three workpiece bodies 14 will not shift during the clamping process, avoiding the problems of difficult operation and misalignment when clamping multiple workpiece bodies 14 in the prior art. During the process of pushing the connecting block 12 downward, the connecting block 12 can also control the round rod 10 and the round rod 11 to move away from the workpiece body 14 to prevent the round rod 10 and the round rod 11 from interfering with the grinding of the workpiece body 14, and this process can be realized only by manually increasing the downward movement stroke of the connecting block 12 without additional control, further reducing the difficulty of manual operation and being beneficial to improving convenience.

[0044] Embodiment

[0045] On the basis of Embodiment 1, as Figures 3-7 shown, the vertical surface of the connecting plate 8 in contact with the corresponding side plate 3 is set as an inclined surface.

[0046] It further includes a pull rod 2011; a pull rod 2011 is bolted to each second fixing block 209. Manually hold the pull rod 2011, and then pull the second fixing block 209 to move through the pull rod 2011, with strong convenience.

[0047] It further includes a third fixing block 2012; a third fixing block 2012 is fixedly connected to the opposite sides of the first fixing blocks 7 at both ends; a third fixing block 2012 is fixedly connected to both sides of the first fixing blocks 7 other than the two ends; a plurality of grooves are formed in each third fixing block 2012, which is beneficial to improving the friction force, thereby improving the fixing effect on the workpiece body 14.

[0048] The working principle of the above embodiment is as follows:

[0049] After the grinding described in Embodiment 1 is completed:

[0050] The debris generated by the rough grinding of the workpiece body 14 is relatively sharp. The sharp debris will adhere to the surface of the workpiece body 14 after grinding. At the same time, the surface roughness of the workpiece body 14 is large after rough grinding. Especially at the edge position of the workpiece body 14, sharp burrs will remain, resulting in the fingers being easily pricked by the sharp debris and scratched by the burrs when manually removing the ground workpiece body 14. First, manually place the external storage box under the slideway 2. When the first fixing block 7 stops clamping the workpiece body 14, the workpiece body 14 falls back onto the two first round rods 10. Then, manually pull the second fixing block 209 once to move the second fixing block 209 away from the through slot 91, so that the second fixing block 209 stops fixing the connecting plate 8. Then, the first spring 9 rebounds to drive the connecting plate 8 to move upward back to its original position. During this process, since the vertical surface of the connecting plate 8 in contact with the corresponding side plate 3 is set as an inclined surface, the connecting plate 8 slides obliquely forward. When the connecting plate 8 stops suddenly at the extreme position of movement, the workpiece body 14 resting on the two first round rods 10 continues to move due to inertia, so that the ground workpiece body 14 is thrown obliquely forward into the slideway 2. At this time, the workpiece body 14 is buffer - protected by the buffer pad on the slideway 2, and then falls along the slideway 2 into the external storage box to complete the removal operation. When in use, during the reset process of the connecting plate 8 and the parts thereon, the ground workpiece body 14 can be thrown forward into the slideway 2 to complete the material removal operation, without the need for manual removal operation, preventing the manual fingers from being pricked by the debris and scratched by the burrs, and there is no need to set other material - taking mechanisms for the removal operation, with a clever structure.

[0051] According to the above working principle, we can know that the present invention has the following effects:

[0052] During the reset process of the connecting plate 8 and the parts thereon, the ground workpiece body 14 can be thrown forward into the slideway 2 to complete the material removal operation, without the need for manual removal operation, preventing the manual fingers from being pricked by the debris and scratched by the burrs, and there is no need to set other material - taking mechanisms for the removal operation, with a clever structure.

[0053] On the basis of the above - mentioned technical effects, the present invention also has the following advantages:

[0054] First, manually hold the pull rod 2011, and then pull the second fixing block 209 to move through the pull rod 2011, with strong convenience.

[0055] Second, the third fixing block 2012 is used to clamp and fix the workpiece body 14 instead of the first fixing block 7. A number of grooves are formed on the third fixing block 2012, which is beneficial to improving the friction force, thereby improving the fixing effect on the workpiece body 14.

[0056] Embodiment

[0057] On the basis of Embodiment 2, as Figure 8 andFigure 9 As shown, it further includes a second magnet 2013; a second magnet 2013 is fixedly connected to the upper side of each connecting plate 8; a second magnet 2013 is also fixedly connected to each side plate 3.

[0058] It further includes a pressing plate 2014; a pressing plate 2014 is detachably connected to the upper side of each connecting plate 8; a pressing plate 2014 is also detachably connected to each side plate 3. The pressing plate 2014 is made of alloy material; every two adjacent pressing plates 2014 are in contact; each pressing plate 2014 is in contact with the corresponding second magnet 2013, and the second magnet 2013 is fixed and protected by the pressing plate 2014; a square groove is provided in the middle of the pressing plate 2014.

[0059] The first connecting block 12 is made of soft rubber material.

[0060] The working principle of the above embodiment is as follows:

[0061] During the process that the first spring 9 rebounds and drives the connecting plate 8 to move upward to the original position described in Embodiment 2:

[0062] The connecting plate 8 drives the second magnet 2013 to move upward. In the last stage of the upward movement of the connecting plate 8, the adjacent second magnets 2013 above and below gradually approach. At this time, the adjacent second magnets 2013 above and below generate magnetic attraction force, and the magnetic attraction force acts on the connecting plate 8, thereby increasing the movement speed of the connecting plate 8 in the last stage, which is more conducive to throwing out the polished workpiece body 14. And after the connecting plate 8 moves to the limit position, the adjacent second magnets 2013 above and below are attracted tightly by magnetic force, thereby preventing the connecting plate 8 from rebounding due to impact, that is, the connecting plate 8 and the parts thereon can be immediately stationary, which is conducive to immediately performing the next round of clamping and polishing operations, thereby improving the efficiency. During this process, the second magnet 2013 is protected by the pressing plate 2014 to prevent damage caused by high-speed impact of the adjacent second magnets 2013 above and below.

[0063] According to the above working principle, we can know that the present invention has the following effects:

[0064] The magnetic attraction force generated by the second magnet 2013 acts on the connecting plate 8, thereby increasing the movement speed of the connecting plate 8 in the last stage, which is more conducive to throwing out the polished workpiece body 14. At the same time, during the reset process, the adjacent second magnets 2013 above and below are attracted tightly by magnetic force, so that the connecting plate 8 and the parts thereon can be immediately stationary, which is conducive to immediately performing the next round of clamping and polishing operations, thereby improving the efficiency. At the same time, the second magnet 2013 is protected by the pressing plate 2014 to prevent damage caused by high-speed impact of the adjacent second magnets 2013 above and below.
