Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically to a fine grinding device for alumina materials. Background Technology

[0002] A grinding machine is a grinding machine that uses abrasive-coated or embedded grinding tools to grind the surface of a workpiece. It is mainly used for grinding high-precision flat surfaces, internal and external cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces, and other profiled surfaces of workpieces. The main types of grinding machines include disc grinding machines, spindle grinding machines, and various special-purpose grinding machines.

[0003] Publication number CN111250220B discloses a grinding mill. By starting a motor, a second gear rotates, which in turn drives a splined shaft to rotate, thereby causing the grinding head to move. Simultaneously, due to the use of gear transmission, the splined shafts of different circumferential layers rotate in different directions, thus causing the grinding head to rotate in opposite directions, thereby improving the grinding effect and efficiency. However, this patent still has the following problems in actual use:

[0004] By starting the motor, gear two rotates, which in turn drives the spline shaft to rotate, thereby causing the grinding head to start moving. At the same time, due to the use of gear transmission, the spline shafts of different circumferences rotate in different directions, which in turn causes the grinding head to rotate in the opposite direction, thereby improving the grinding effect and grinding efficiency. However, after the above device finishes grinding the alumina material, the staff needs to clean the powder on the grinding head, which not only increases the workload of the staff, but also reduces the grinding efficiency to a certain extent.

[0005] A fine grinding device for alumina materials is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a fine grinding device for alumina materials, to solve the problem mentioned in the background art. Currently, the device uses a motor to rotate a second gear, which in turn rotates a splined shaft, thus driving the grinding head to move. Because of the gear transmission, the splined shafts of different circumferential layers rotate in different directions, causing the grinding head to rotate in the opposite direction, thereby improving the grinding effect and efficiency. However, after grinding the alumina material, the device requires workers to clean the powder from the grinding head, which not only increases the workload of the workers but also reduces the grinding efficiency to some extent.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fine grinding device for alumina materials, comprising a support base, wherein a cylinder is fixedly installed on one side of the top surface of the support base;

[0008] An extension plate is fixedly connected to the top surface of the cylinder. A motor housing is fixedly connected to the bottom surface of the extension plate away from the cylinder. A stepper motor is fixedly installed inside the motor housing. A grinding disc is fixedly installed on one side surface of the motor housing through the output end of the stepper motor. A grinding worktable is fixedly installed on one side of the cylinder.

[0009] Also includes:

[0010] A fixing plate is fixedly connected to one side of the grinding table;

[0011] An electric push rod is fixedly installed on one side of the fixed plate near the middle.

[0012] The surface of the electric actuator is connected to a fixed frame.

[0013] Preferably, one side surface of the fixing frame is fixedly connected to the fixing plate, the side surface of the electric push rod away from the fixing frame is fixedly connected to the support plate, the top surface of the support plate is fixedly connected to the stabilizing plate, and the top surface of the stabilizing plate is fixedly installed with a cleaning pad.

[0014] Preferably, the cleaning pad has several threaded grooves symmetrically formed on both sides of its surface.

[0015] Preferably, a plurality of connecting blocks are symmetrically installed on both sides of the surface of the stabilizing plate, and a threaded pin is threadedly connected through the middle of the surface of the connecting block near the top, and the threaded pin is threadedly connected to the threaded groove.

[0016] Preferably, a collection box is fixedly installed on one side of the bottom surface of the support base, and the collection box is connected in a through manner to the grinding worktable.

[0017] Preferably, connecting plates are symmetrically installed on both sides of the extension plate, and the surface of the connecting plates is provided with a sliding groove, and a slider is slidably connected inside the sliding groove.

[0018] Preferably, the slider is fixedly connected to the extension plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This fine grinding equipment for alumina materials, through the cooperation of a fixed plate, electric push rod, fixed frame, support plate, stabilizing plate, cleaning pad, threaded groove, connecting block and threaded pin, enables automated cleaning of the grinding disc, thereby reducing the workload of workers to a certain extent. At the same time, automated cleaning also improves the cleaning efficiency of the grinding disc, thereby improving the grinding efficiency. The specific details are as follows:

[0020] 1. By setting up a fixed plate, electric push rod, fixed frame, support plate, stabilizing plate, cleaning pad, threaded groove, connecting block, and threaded pin, when cleaning the grinding disc is required, the grinding disc is raised to a certain height, and the electric push rod is activated via the control terminal. The output end of the electric push rod drives the support plate to move. The movement of the support plate drives the stabilizing plate and the cleaning pad to move, thus moving the cleaning pad directly below the grinding disc. Then, the grinding disc is lowered until the bottom of the grinding disc contacts the top of the cleaning pad. The stepper motor is then activated via the control terminal. The stepper motor rotates at a low speed, and through its rotation, the grinding disc... The output of the stepper motor drives the grinding disc to rotate, which causes friction between the grinding disc and the cleaning pad. This allows the cleaning pad to clean the powder on the grinding disc. When the cleaning pad needs to be replaced after long-term use, the multiple threaded pins are rotated to separate from the multiple threaded grooves, allowing the cleaning pad to be disassembled. When installing the cleaning pad, it is placed on the stabilizing plate, and the threaded grooves are aligned with the holes on the connecting block. The threaded pins are then screwed into the threaded grooves to complete the installation of the cleaning pad. This improves the cleaning efficiency of the grinding disc to a certain extent.

[0021] 2. By configuring a cylinder, extension plate, motor housing, stepper motor, grinding disc, grinding table, collection box, connecting plate, slide groove, and slider, after the alumina material is placed on the perforated plate inside the grinding table, the cylinder is activated via the control terminal. This causes the cylinder's output to lower the extension plate. Simultaneously, the lowering of the extension plate causes the slider to slide within the slide groove. The lowering of the extension plate also causes the motor housing, stepper motor, and grinding disc to descend. Once the grinding disc has descended into the grinding table, the stepper motor is activated via the control terminal. The output end drives the rotation of the grinding disc, which allows the alumina material on the perforated plate to be ground. The holes on the perforated plate are small, so only alumina material that meets the grinding requirements can pass through the holes and enter the collection box. The perforated plate is fixed to the grinding table with bolts. The grinding disc is a planetary grinding disc, which improves the abrasive shearing efficiency and reduces the grinding time by 30%. The inner wall of the grinding table must be made of wear-resistant material to prevent material from falling off and contaminating the alumina powder during the grinding process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a fine grinding device for alumina materials, including a support base 1, a cylinder 2 fixedly mounted on one side of the top surface of the support base 1; an extension plate 3 fixedly connected to the top surface of the cylinder 2, a motor housing 4 fixedly connected to the bottom surface of the extension plate 3 away from the cylinder 2, a stepper motor 5 fixedly mounted inside the motor housing 4, a grinding disc 6 fixedly mounted on one side of the output end of the stepper motor 5 passing through the motor housing 4, and a grinding worktable 7 fixedly mounted on one side of the cylinder 2; it also includes: a fixing plate 8 fixedly connected to one side of the grinding worktable 7; wherein, an electric push rod 9 is fixedly mounted on the surface of the fixing plate 8 near the middle; wherein, a fixing frame 10 is connected through the surface of the electric push rod 9, such as Figure 1-5 As shown, by setting up the cooperation between the fixed plate 8, electric push rod 9, fixed frame 10, support plate 11, stabilizing plate 12, cleaning pad 13, threaded groove 18, connecting block 19 and threaded pin 20, the grinding disc 6 is automatically cleaned, thereby reducing the workload of the staff to a certain extent. At the same time, the automated cleaning also improves the cleaning efficiency of the grinding disc 6, thereby improving the grinding efficiency.

[0030] One side surface of the fixed frame 10 is fixedly connected to the fixed plate 8. A support plate 11 is fixedly connected to the side surface of the electric push rod 9 away from the fixed frame 10. A stabilizing plate 12 is fixedly connected to the top surface of the support plate 11. A cleaning pad 13 is fixedly installed on the top surface of the stabilizing plate 12. Several threaded grooves 18 are symmetrically opened on both sides of the surface of the cleaning pad 13. Several connecting blocks 19 are symmetrically installed on both sides of the surface of the stabilizing plate 12. A threaded pin 20 is threadedly connected to the middle of the surface of the connecting block 19 near the top. The threaded pin 20 is threadedly connected to the threaded groove 18. A collection box 14 is fixedly installed on one side of the bottom surface of the support base 1. The collection box 14 is connected to the grinding worktable 7. Figure 1 , 3 As shown in Figures 4 and 5, when cleaning the grinding disc 6 is required, the grinding disc 6 is raised to a certain height, and then the electric push rod 9 is activated via the control terminal. The output end of the electric push rod 9 drives the support plate 11 to move. The movement of the support plate 11 causes the stabilizing plate 12 and the cleaning pad 13 to move, thus moving the cleaning pad 13 directly below the grinding disc 6. Then, the grinding disc 6 is lowered until its bottom contacts the top of the cleaning pad 13. The stepper motor 5 is then activated via the control terminal. The stepper motor 5 rotates at a relatively low speed, and its output end drives the grinding disc 6 to rotate, causing friction between the grinding disc 6 and the cleaning pad 13. The cleaning pad 13 can clean the powder on the grinding disc 6. When the cleaning pad 13 needs to be replaced after long-term use, it can be disassembled by rotating the threaded pins 20 to separate the multiple threaded pins 20 from the multiple threaded grooves 18. When installing the cleaning pad 13, it is placed on the stabilizing plate 12, and then the threaded grooves 18 are aligned with the holes on the connecting block 19. The threaded pins 20 are screwed into the threaded grooves 18 to complete the installation of the cleaning pad 13. This improves the cleaning efficiency of the grinding disc 6 to a certain extent. The electric push rod 9 is model LAM33-A and is electrically connected to the control end.

[0031] Connecting plates 15 are symmetrically installed on both sides of the extension plate 3. The surface of each connecting plate 15 has a groove 16, and a slider 17 is slidably connected inside the groove 16. The slider 17 is fixedly connected to the extension plate 3. Figure 2As shown, after the alumina material is placed on the perforated plate inside the grinding table 7, the cylinder 2 is activated via the control terminal, causing the output end of the cylinder 2 to drive the extension plate 3 to descend. Simultaneously, the descent of the extension plate 3 causes the slider 17 to slide within the slide groove 16. This descent of the extension plate 3 also causes the motor housing 4, stepper motor 5, and grinding disc 6 to descend. After the grinding disc 6 descends into the grinding table 7, the stepper motor 5 is activated via the control terminal, causing the output end of the stepper motor 5 to drive the rotation of the grinding disc 6. This allows the alumina material on the perforated plate to be ground. The holes on the plate are small, allowing only alumina material that meets the grinding requirements to pass through and enter the collection box 14. The perforated plate is fixed to the grinding table 7 with bolts. The grinding disc 6 is a planetary grinding disc as used in the prior art, which improves the abrasive shearing efficiency and shortens the grinding time by 30%. The inner wall of the grinding table 7 must be made of wear-resistant materials such as zirconia ceramic or polyurethane to prevent material from falling off and contaminating the alumina powder during the grinding process. The stepper motor 5 is model 86BYG250-113, and the stepper motor 5 is electrically connected to the control terminal.

[0032] Working principle: Before using this alumina fine grinding equipment, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, firstly, by setting up a fixed plate 8, an electric push rod 9, a fixed frame 10, a support plate 11, a stabilizing plate 12, a cleaning pad 13, a threaded groove 18, a connecting block 19, and a threaded pin 20, when it is necessary to clean the grinding disc 6, after the grinding disc 6 is raised to a certain height, the electric push rod 9 is activated through the control terminal, so that the output end of the electric push rod 9 drives the support plate 11 to move. The movement of the support plate 11 drives the stabilizing plate 12 and the cleaning pad 13 to move, so that the cleaning pad 13 moves directly below the grinding disc 6. Then, the grinding disc 6 is lowered so that the bottom of the grinding disc 6 contacts the top of the cleaning pad 13. Then, the stepper motor 5 is activated through the control terminal, so that the rotation speed of the stepper motor 5 is relatively small, and the rotation of the stepper motor 5... The stepper motor 5 drives the grinding disc 6 to rotate, causing friction between the grinding disc 6 and the cleaning pad 13. This allows the cleaning pad 13 to clean the powder on the grinding disc 6. When the cleaning pad 13 needs to be replaced after long-term use, the threaded pins 20 are rotated to separate them from the threaded grooves 18, allowing the cleaning pad 13 to be disassembled. When installing the cleaning pad 13, it is placed on the stabilizing plate 12, and the threaded grooves 18 are aligned with the holes on the connecting block 19. The threaded pins 20 are then screwed into the threaded grooves 18 to complete the installation of the cleaning pad 13. This improves the cleaning efficiency of the grinding disc 6 to a certain extent.

[0033] Secondly, by setting up cylinder 2, extension plate 3, motor housing 4, stepper motor 5, grinding disc 6, grinding table 7, collection box 14, connecting plate 15, slide groove 16, and slider 17, after the alumina material is placed on the perforated plate inside the grinding table 7, cylinder 2 is activated via the control terminal, causing the output end of cylinder 2 to drive the extension plate 3 to descend. Simultaneously, the descent of extension plate 3 causes slider 17 to slide within slide groove 16. This descent of extension plate 3 also drives the motor housing 4, stepper motor 5, and grinding disc 6 to descend. After the grinding disc 6 descends into the grinding table 7, stepper motor 5 is activated via the control terminal. The stepper motor 5 drives the grinding disc 6 to rotate, thus grinding the alumina material on the perforated plate. The holes on the perforated plate are small, so only alumina material that meets the grinding requirements can pass through the holes and enter the collection box 14. The perforated plate and the grinding table 7 are fixedly installed with bolts. The grinding disc 6 is a planetary grinding disc 6 in the prior art, which improves the abrasive shearing efficiency and shortens the grinding time by 30%. The inner wall of the grinding table 7 must be made of wear-resistant materials such as zirconia ceramics or polyurethane to prevent material from falling off and contaminating the alumina powder during the grinding process.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
