Description

Technical Field

[0001] This utility model relates to the technical field of grinding wheel production, and in particular to a grinding wheel chipping machine. Background Technology

[0002] In the manufacturing process of grinding wheels, sand, binder, and other auxiliary materials are first thoroughly mixed as raw materials until the mixture is evenly distributed, which is the molding material. The molding material is then placed into a molding mold, and a rotating spreading device evenly spreads it within the mold. After the mold stops rotating, the material is pressed under high pressure by a press, and then cured at high temperature in an oven to produce the finished product.

[0003] In the grinding wheel production process, high-temperature curing is the most critical step. This step involves first mounting the molded resin grinding wheel and spacer material onto a grinding wheel clamping fixture, and then placing the fixture and fixture together into a curing oven. Currently, the clamping fixture is generally installed manually by workers, which is time-consuming, labor-intensive, inefficient, and prone to errors, resulting in defective products.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 3 A grinding wheel chip encoder includes a housing 1, a support frame 11 fixed on the top of the housing 1, a grinding wheel gripping and dispensing device 2 installed on the support frame 11, the grinding wheel gripping and dispensing device 2 includes a drive belt 21, a first connecting block 22 fixed at the bottom of the drive belt 21, and an mounting plate 23 fixed at the bottom of the first connecting block 22, the mounting plate 23 being arranged along the length direction of the drive belt 21.

[0026] The drive belt 21 is a synchronous belt, driven by belt drive pulleys 211 at both ends. A belt motor 214 is fixed on the side wall of the support frame 11, driving one of the belt drive pulleys 211 to rotate, thereby rotating the drive belt 21. Multiple belt support pulleys 212 are arranged between the two belt drive pulleys 211, providing support for the drive belt 211 and increasing its stability. A support slide rail 213 is fixed on the support frame 11, passing through the first connecting block 22, allowing the first connecting block 22 to slide along the support slide rail 213. The support slide rail 213 increases the stability of the first connecting block 22 and the mounting plate 23.

[0027] The mounting plate 23 is equipped with a vacuum suction cup 24, a first magnet 25, and a second magnet 26, which are arranged sequentially along the length of the mounting plate 23. The vacuum suction cup 24 is used to grip aluminum plates, the first magnet 25 is used to grip grinding wheels, and the second magnet 26 is used to grip steel mesh.

[0028] When stacking grinding wheels, a steel mesh is placed between two adjacent grinding wheels. To prevent the grinding wheels from hardening at high temperatures, the steel mesh is used to bond the two adjacent grinding wheels together. After placing several grinding wheels and the steel mesh, an aluminum plate is placed on top to prevent the grinding wheels from being squeezed and deformed. The grinding wheels are gripped by a first magnet 25, and the steel mesh is gripped by a second magnet 26. This reduces the use of compressed air, saving energy. Furthermore, the steel mesh can only be gripped by magnets; suction cups cannot. The surface of suction cups is easily worn; using magnets for gripping prevents magnet damage and improves economic efficiency.

[0029] Above both the first magnet 25 and the second magnet 26 is a corresponding push cylinder 251. The push cylinder 251 is fixed to the bottom of the mounting plate 23. A connecting plate 252 is fixed to the end of the push cylinder 251 near the first magnet 25. A fixing post 253 is fixed to the bottom of the connecting plate 252. The piston rod of the push cylinder 251 above the first magnet 25 passes through the connecting plate 252 and is fixed to the first magnet 25. The piston rod of the push cylinder 251 above the second magnet 26 passes through the corresponding connecting plate 252 and is fixed to the second magnet 26.

[0030] When the first magnet 25 grips the grinding wheel, it pushes the piston rod of the cylinder 251 to extend, and the first magnet 25 attracts the grinding wheel. Then, the drive belt 21 transports the first magnet 25 to directly above the code plate positioning post 531, pushing the piston rod of the cylinder 251 to retract. When the piston rod retracts, the end of the fixing post 253 away from the connecting plate 252 abuts against the grinding wheel, thereby detaching the grinding wheel from the first magnet 25, and the grinding wheel falls onto the code plate tray 53. Similarly, the steel mesh falls from the second magnet 26 onto the code plate positioning post 531.

[0031] Reference Figure 1 , Figure 4 and Figure 5 The housing 1 is equipped with a grinding wheel placement device 3, a steel mesh placement device 6, an aluminum plate placement device 8, and a chip placement device 5. The grinding wheel placement device 3 includes a first gear 31, a rack 32, and a grinding wheel tray 33. A first support plate 12 is provided on the top surface of the housing 1, and a support block 121 is fixed to the bottom of the first support plate 12. The support block 121 is fixed to the top surface of the housing 1. The rack 32 is located above the first support plate 12 and is slidably connected to the first support plate 12. The first gear 31 meshes with the rack 32, and a first motor that drives the first gear 31 to rotate is installed inside the housing 1.

[0032] Three grinding wheel trays 33 are sequentially fixed to the rack 32 and arranged along the length of the rack 32. Each grinding wheel tray 33 is fixed with a grinding wheel positioning post 331, and a stack of grinding wheels is placed on the grinding wheel positioning post 331. The purpose of setting up three grinding wheel trays 33 is that when the grinding wheels on one of the grinding wheel trays 33 are all gripped, the first motor will drive the gear to rotate, and the gear will drive the rack 32 and the three grinding wheel trays 33 to move. The next grinding wheel tray 33 will move to the underside of the mounting plate 23, and the first magnet 25 will grip the grinding wheels on the grinding wheel tray 33 located directly under the mounting plate 23. The grinding wheel tray 33 with all the grinding wheels gripped will detach from the underside of the mounting plate 23, and the operator can then place a stack of grinding wheels on the tray grinding wheels, thus preventing the chip stacking machine from stopping and improving work efficiency.

[0033] The grinding wheel tray 33 has two lifting holes 332. The housing 1 is equipped with a grinding wheel lifting device 4. The grinding wheel lifting device 4 includes a lifting cylinder 41. The bottom end of the lifting cylinder 41 is fixed to the bottom wall inside the housing 1. A second connecting block 42 is fixed on the piston rod of the lifting cylinder 41. Two lifting columns 43 are fixed on the second connecting block 42. The lifting columns 43 penetrate the first support plate 12 upward and can extend out from the lifting holes 332.

[0034] When gripping the grinding wheel, the drive belt 21 first moves the first magnet 25 to directly above the grinding wheel positioning column 331 located directly below the mounting plate 23. The piston rod of the lifting cylinder 41 extends, and the second connecting block 42 drives the lifting column 43 upward, thus pushing a stack of grinding wheels upward. The topmost grinding wheel is attracted by the first magnet 25. When the lifting column 43 descends, except for the topmost grinding wheel which is attracted by the first magnet 25, the remaining grinding wheels fall back to their initial position.

[0035] Reference Figure 1 , Figure 6 and Figure 7The chip placement device 5 includes a second support plate 51, which is an arc-shaped plate. The second support plate 51 is rotatably connected to the top of the housing 1. A drive assembly 52 for driving the second support plate 51 to rotate is provided on the housing 1. The drive assembly 52 includes an arc-shaped rack 521, a gear, and a second motor. The arc-shaped rack 521 is fixed to the bottom of the second support plate 51. The second gear 522 meshes with the arc-shaped rack 521. The second motor is fixed inside the housing 1. The second motor drives the second gear 522 to rotate, and the second gear 522 drives the arc-shaped rack 521 to rotate, thereby causing the second support plate 51 to rotate.

[0036] Multiple chip trays 53 are fixed on the side wall of the second support plate 51. The multiple chip trays 53 are arranged along the arc direction of the second support plate 51. A chip positioning post 531 is fixed on the chip tray 53. One of the chip trays 53 is positioned directly below the mounting plate 23. Under the action of the drive belt 21, the grinding wheel attracted by the first magnet 25 is transported to the top of the chip tray 53. When the piston rod of the push cylinder 251 retracts, under the action of the fixing post 253, the grinding wheel disengages from the first magnet 25, and the grinding wheel falls onto the chip tray 53. The chip positioning post 531 passes through the center hole of the grinding wheel.

[0037] Once a chip tray 53 is filled with grinding wheels, the second motor drives the second support plate 51 to rotate, thereby moving the next chip tray 53 directly below the mounting plate 23.

[0038] The steel mesh placement device 6 includes a steel mesh tray 62, a third support plate 61, and a steel mesh positioning post 621. The third support plate 61 is fixed to the side wall of the support frame 11 and is located above the second support plate 51. Two steel mesh trays 62 are mounted on the third support plate 61. The two steel mesh trays 62 are vertically arranged, and their ends are fixedly connected to each other. A first rotating shaft 63 is fixed on the third support plate 61, and the connection between the two steel mesh trays 62 is rotatably connected to the first rotating shaft 63. A first cylinder 64 for driving the steel mesh tray 62 to rotate is mounted on the second support plate 51. One of the steel mesh trays 62 is located directly below the mounting plate 23, and the steel mesh positioning post 621 is fixed on the steel mesh tray 62. A stack of steel mesh is placed on top of the steel mesh tray 62.

[0039] A steel mesh lifting device 7 is installed below the third support plate 61. The structure of the steel mesh lifting device 7 is the same as that of the grinding wheel lifting device 4. A clearance hole 511 is provided on the second support plate 51. The lifting column 43 of the steel mesh lifting device 7 passes through the clearance hole 511. When the second motor drives the second support plate 51 to rotate, the second support plate 51 does not affect the lifting of the lifting column 43 of the steel mesh lifting device 7. Lifting holes 332 are provided on both the third support plate 61 and the steel mesh tray 62.

[0040] When the steel mesh is grasped, the drive belt 21 drives the mounting plate 23 to move, causing the second magnet 26 to move directly above the steel mesh. The lifting cylinder 41 of the steel mesh lifting device 7 drives the lifting column 43 to push a stack of steel mesh upwards. The second magnet 26 attracts the topmost steel mesh. Then, the drive belt 21 moves the second magnet 26 directly above the chip tray 53. The pushing cylinder 251 above the second magnet 26 retracts, and under the action of the fixing column 253, the steel mesh detaches from the second magnet 26 and falls above the chip tray 53. When all the steel mesh on the steel mesh tray 62 is grasped, the first cylinder 64 drives the steel mesh tray 62 to rotate, causing the other steel mesh tray 62 to rotate directly below the mounting plate 23. By setting up two steel mesh trays 62, when the steel mesh on one steel mesh tray 62 is grasped, the other steel mesh tray 62 is put into operation, allowing workers to promptly place the steel mesh onto the empty steel mesh tray 62, thus improving work efficiency.

[0041] Reference Figure 1 , Figure 4 and Figure 5 The aluminum plate placement device 8 includes a rotating tray 81, on which three aluminum plate positioning posts 82 are fixed. The three aluminum plate positioning posts 82 are evenly arranged along the circumference of the rotating tray 81, and each aluminum plate positioning post 82 corresponds to a stack of aluminum plates. A second rotating shaft 83 is located at the center of the rotating tray 81, and the second rotating shaft 83 is rotatably connected to the first support plate 12. A third motor that drives the second rotating shaft 83 to rotate is installed inside the housing 1. One of the aluminum plate positioning posts 82 is located directly below the mounting plate 23. An aluminum plate lifting device 9 is installed inside the housing 1 to lift the aluminum plates. The structure of the aluminum plate lifting device 9 is the same as that of the grinding wheel lifting device 4.

[0042] When the aluminum plate is gripped, the drive belt 21 drives the vacuum suction cup 24 to move directly above the aluminum plate. The lifting cylinder 41 of the aluminum plate lifting device 9 drives the lifting column 43 to move upward. The lifting column 43 pushes the aluminum plate upward. The top aluminum plate is attracted by the vacuum suction cup 24. Then the drive belt 21 moves the aluminum plate directly above the code tray 53, and the aluminum plate falls onto the code tray 53.

[0043] The implementation principle of this utility model of a grinding wheel chip encoder is as follows: A grinding wheel, a steel mesh, and an aluminum plate are placed on a grinding wheel tray 33, a steel mesh tray 62, and a rotating tray 81, respectively. First, the drive belt 21 drives the mounting plate 23 to move, so that the first magnet 25 moves directly above the grinding wheel tray 33. The grinding wheel lifting device 4 drives the grinding wheel to move upward, and the push cylinder 251 pushes the first magnet 25 downward. The first magnet 25 attracts the grinding wheel. Then, the drive belt 21 drives the first magnet 25 to directly above the chip tray 53. The push cylinder 251 above the first magnet 25 retracts. Under the action of the fixing column 253, the grinding wheel disengages from the first magnet 25, and the first magnet 25 falls onto the chip tray 53. The chip positioning column 531 passes through the center hole of the grinding wheel.

[0044] Then, the drive belt 21 drives the second magnet 26 to directly above the steel mesh tray 62. The second magnet 26 attracts the steel mesh, and the drive belt 21 drives the second magnet 26 to move directly above the chip tray 53. Under the action of the fixing column 253, the steel mesh detaches from the second magnet 26 and falls onto the chip tray 53. This process is repeated. When there are five grinding wheels and five steel meshes staggered on the chip tray 53, the vacuum suction cup 24 attracts the aluminum plate and places it above the chip tray 53. When one chip tray 53 is full, the second motor drives the second gear 522 to rotate. The second gear 522 drives the arc rack 32 and the chip tray 53 to rotate, and the next chip tray 53 moves directly below the mounting plate 23, continuing the chip-coding process. By using the chip-coding machine of this utility model to code grinding wheels, manpower is saved and work efficiency is improved.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
