Description
Technical Field
[0001] This utility model relates to the field of grinding wheel processing technology, and in particular to a grinding wheel processing mold. Background Technology
[0002] A grinding wheel is a solid mold, mainly made of materials such as diamond or cubic boron nitride (hereinafter referred to as "grind"). The grinding wheel is bonded together with a binder and pressed into a disc shape by a pressing device. After drying and firing, it finally becomes a grinding wheel. The grinding wheel can perform rough grinding and semi-fine grinding on metal or non-metal parts by rotating at high speed.
[0003] During the manufacturing process of grinding wheels, workers place abrasive stones into a pressing cylinder and use special tools to stir and level the stones. Since grinding wheels come in different specifications, the amount of abrasive stones used also varies. Workers need to add different amounts of abrasive stones according to the different specifications of the grinding wheel. The amount of abrasive stones needs to be judged manually, but the accuracy of manual judgment is low and there is a large error. Although grinding wheels can be successfully manufactured in this way, the life of the grinding wheel is greatly reduced due to the existence of large errors. Utility Model Content

Detailed Implementation
[0014] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0015] A grinding wheel machining mold, such as Figures 1-7 As shown, the device includes a workbench 1, a pressing device 2 on the top of the workbench 1, a pressing cylinder 3 on the top of the workbench 1, a top cover 4 inside the pressing cylinder 3, and a metering device. The metering device includes a small base plate 8. A semi-circular groove is opened on the top of the workbench 1, and a small base plate 8, a medium base plate 9, and a large base plate 10 are slidably connected in the semi-circular groove. The small base plate 8, the medium base plate 9, and the large base plate 10 are in contact with each other and are arranged in order of size. The tops of the small base plate 8, the medium base plate 9, and the large base plate 10 can contact the pressing cylinders 3 of different sizes. An elastic airbag 11 is fixedly installed at the bottom of the small base plate 8, the medium base plate 9, and the large base plate 10. The bottom of the elastic airbag 11 is fixedly connected to the bottom of the semi-circular groove of the workbench 1. The elastic airbag 11 is filled with gas and is initially inflated, so that the tops of the small base plate 8, the medium base plate 9, and the large base plate 10 are higher than the top of the workbench 1.
[0016] The small base plate 8, medium base plate 9, large base plate 10, and elastic airbag 11 are all in a semi-circular state, with the opening of the semicircle facing the pressing device 2. This state allows the pressing cylinder 3 to move without being restricted by the small base plate 8, medium base plate 9, and large base plate 10.
[0017] The metering device also includes a connecting tube 12. The bottom of each of the three elastic airbags 11 is fixedly connected to the connecting tube 12. The other end of each of the three connecting tubes 12 passes through the workbench 1 and is fixedly connected to the same pneumatic telescopic rod 13. The fixed end of the pneumatic telescopic rod 13 is fixedly connected to a fixed plate 15. The telescopic end of the pneumatic telescopic rod 13 is fixedly connected to a push plate 16. A spring 14 is connected between the fixed plate 15 and the push plate 16. A rack 17 is fixedly connected to the side of the push plate 16 away from the pneumatic telescopic rod 13. A gear 18 meshes with one side of the rack 17.
[0018] The metering device also includes a discharge cylinder 5. The discharge cylinder 5 is fixedly connected to the top of the workbench 1. A collection trough 6 is opened on the top of the discharge cylinder 5. A discharge port is opened through the bottom of the collection trough 6, and an automatic opening and closing door 7 is installed at the discharge port. The pneumatic telescopic rod 13 is located on the outer wall of the discharge cylinder 5 and passes through the discharge cylinder 5. The bottom of the fixed end of the pneumatic telescopic rod 13 and the bottom of the fixed plate 15 are both fixedly connected to the discharge cylinder 5 through a connecting plate. The bottom of the push plate 16 and the rack 17 are slidably connected to the bottom of the inner side of the discharge cylinder 5. The gear shaft of the gear 18 is rotatably connected to the bottom of the inner side of the discharge cylinder 5.
[0019] The metering device also includes a shaped rotating disk 19, a fixed disk 25 is fixedly installed inside the discharge cylinder 5, the gear shaft of the gear 18 rotates through the fixed disk 25 and is fixedly installed on the shaped rotating disk 19, the bottom of the shaped rotating disk 19 is rotatably connected to the fixed disk 25, and three metering cylinders 20 of different diameters are fixedly installed on the top circumference of the shaped rotating disk 19, and a feeding groove with the same diameter as the metering cylinder 20 is opened at the three metering cylinders 20.
[0020] It also includes a feeding device, which includes a feeding plate 21. The feeding plate 21 is fixedly connected to the discharge cylinder 5. One end of the feeding plate 21 extends through to the outside of the discharge cylinder 5 and is located above the semi-circular groove of the workbench 1. The other end of the feeding plate 21 is located inside the discharge cylinder 5 and is rotatably connected to a rotating column 23. An L-shaped baffle 24 is fixedly installed on the top of the rotating column 23. The top of the L-shaped baffle 24 is flush with the top of the fixed plate 25. The L-shaped baffle 24 can block one of the feeding slots of the irregular rotating plate 19. The position of the L-shaped baffle 24 is vertical to the position of the feeding port of the collecting trough 6. A cylinder 22 is hinged to the bottom of the L-shaped baffle 24. The fixed end of the cylinder 22 is fixedly connected to the feeding plate 21.
[0021] Working principle: First, workers place sand and gravel into the collection trough 6. At this time, the automatic door 7 is closed. Then, the top cover 4 is removed from the pressing cylinder 3, and the pressing cylinder 3 is placed on one of the base plates. Taking the small base plate 8 as an example, the workers place the pressing cylinder 3 on the small base plate 8, with the outer wall of the pressing cylinder 3 in contact with the inner side of the medium base plate 9. Since the pressing cylinder 3 is made of iron, it has a certain weight. When the pressing cylinder 3 is placed on the small base plate 8, it presses the small base plate 8 downward and squeezes the elastic airbag 11 connected to the small base plate 8. The gas inside the elastic airbag 11 flows into the pneumatic telescopic rod 13 through the connecting pipe 12. When the elastic airbag 11 is fully squeezed, the top of the small base plate 8 is at the same position as the top of the workbench 1. In a level state, when gas flows into the pneumatic telescopic rod 13, the telescopic end of the pneumatic telescopic rod 13 is pushed and extended by the gas, causing the rack 17 to slide. The sliding of the rack 17 causes the gear 18 to rotate. The gear 18 drives the irregular rotating disk 19 to rotate through the gear shaft. The rotation of the irregular rotating disk 19 drives the three metering cylinders 20 to rotate, and rotates the smallest metering cylinder 20 to the top of the L-shaped baffle 24. At this time, the metering cylinder 20 is located between the top of the L-shaped baffle 24 and the bottom of the discharge port of the collection trough 6. The L-shaped baffle 24 seals the bottom of the discharge trough corresponding to the metering cylinder 20. At this time, the gas has completely entered the pneumatic telescopic rod 13, and the pneumatic telescopic rod 13 no longer extends. At this time, the automatic opening and closing door 7 opens, and the collection trough... The sand and gravel in 6 fall through the discharge port into the metering cylinder 20 at the bottom of the discharge port. When the metering cylinder 20 is full of sand and gravel, the automatic door 7 closes, sealing the discharge port of the collection trough 6. Then, the cylinder 22 retracts, causing the L-shaped baffle 24 to rotate clockwise around the rotating column 23. After the L-shaped baffle 24 rotates, it no longer seals the bottom of the metering cylinder 20, and the sand and gravel in the metering cylinder 20 begin to fall and slide down through the discharge plate 21 to the semi-circular groove of the workbench 1. Since the pressing cylinder 3 is placed above the semi-circular groove of the workbench 1 at this time, the sand and gravel will slide into the pressing cylinder 3. After all the sand and gravel have slid down, the workers use external tools to stir and level the sand and gravel in the pressing cylinder 3. Then, the workers put the top cover 4 on top. Press the sand and gravel inside the pressing cylinder 3 and manually push the pressing cylinder 3 to slide on the workbench 1 so that the pressing cylinder 3 slides to the pressing device 2 for pressing. It should be noted that although the pressing cylinder 3 itself has a certain weight, the staff can still move the pressing cylinder 3 and place the pressing cylinder 3 on the small base plate 8. However, after the pressing cylinder 3 is filled with sand and gravel, it is somewhat difficult for the staff to move the pressing cylinder 3. Therefore, the pressing cylinder 3 is pushed so that it slides to the pressing device 2. The pressing cylinder 3 will slide and disengage from the top of the small base plate 8. At this time, the elastic air bag 11 elastically resets and extracts the gas in the pneumatic telescopic rod 13, causing the pneumatic telescopic rod 13 to retract, thereby driving the irregular rotating disk 19 and the metering cylinder 20 to rotate and reset. It should be noted that since the pressing cylinder 3 needs to slide on the workbench 1, the small base plate 8, medium base plate 9, and large base plate 10 are designed as semi-circular rings, with the semi-circular openings facing the pressing device 2. This allows the pressing cylinder 3 to slide without being restricted by the small base plate 8, medium base plate 9, and large base plate 10. When the pressing cylinder 3 is placed on the small base plate 8, its side wall will contact the inside of the medium base plate 9. When the pressing cylinder 3 is placed on the medium base plate 9, its side wall will contact the inside of the large base plate 10. Contact with the inside of the medium base plate 9 or the large base plate 10 can also position the pressing cylinder 3, allowing the sand and gravel to slide smoothly into the pressing cylinder 3. In the above process, placing the pressing cylinder 3 on the small base plate 8 allows the pneumatic telescopic rod 13 to extend one end of its length. The smaller diameter metering cylinder 20 will rotate to the top of the L-shaped baffle 24. Placing the pressing cylinder 3 on the medium base plate 9 increases the extension distance of the pneumatic telescopic rod 13, causing the larger diameter positioning cylinder 20 to rotate to the top of the L-shaped baffle 24. This process is repeated to quantitatively discharge sand and gravel, avoiding errors caused by manual feeding.
[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
