Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheel production, in particular to a grinding wheel balance detection device for a grinding machine. Background Art

[0002] Grinding wheels are the most important type of abrasive tool used in grinding. They are composed of grit, a binder, and pores. They typically take the form of a support disc with a central or annular hole for mounting on grinding equipment. Grinding wheels are porous bodies made by adding a binder to an abrasive, followed by compaction, drying, and calcination. Grinding wheel properties vary significantly due to differences in abrasive, binder, and manufacturing process, significantly impacting grinding quality, productivity, and economic efficiency. During the manufacturing process, the grinding wheel grains are not uniformly distributed, resulting in uneven balance in the finished grinding wheel, with some areas being lighter and others being heavier. Therefore, grinding wheels must be tested for balance before shipment.

[0003] In the prior art, a Chinese patent document with publication number CN216410496U proposes a balance detection device for grinding wheel production. The second nut is removed by rotating, and then the grinding wheel is placed in the middle of the threaded rod. The second nut is rotated to clamp and fix the threaded rod with the first nut. The threaded rod is then placed in the middle and upper part of the side adjacent to the first roller and the side adjacent to the second roller. If it is rotated, it is unbalanced, otherwise it is balanced. Before use, tap water is injected into the transparent water tank through a water pump. By observing whether the horizontal line on the left side of the transparent water tank is parallel to the water surface, it is judged whether the device is placed on the horizontal surface. In this way, the accuracy of the final horizontal detection result is guaranteed. However, consistent with the traditional method, the fixing device of the traditional grinding wheel balance detection device for grinding machines is very simple, and the fixing effect is often not ideal for grinding wheels of different specifications. The phenomenon of affecting the detection result due to loose fixation often occurs. Moreover, the traditional detection device only judges whether the grinding wheel is balanced by observing whether the mass of the static grinding wheel is uniform. Few devices can detect whether the grinding wheel has reached a balanced state in a dynamic state. The qualified dynamic balance of the grinding wheel can reduce the swing of the grinding wheel during processing after the grinding wheel is installed, thereby ensuring the stability and processing accuracy of the grinding wheel. Utility Model Content

[0004] In view of this, the purpose of the present invention is to propose a grinding wheel balance detection device for a grinding machine to solve the problems that the fixing device is very simple, the fixing is often not firm, and there are few devices that can detect whether the grinding wheel has reached a balanced state in a dynamic state.

[0005] Based on the above purpose, the utility model provides a grinding wheel balance detection device for a grinding machine, comprising: a base, a support plate and an operating platform being mounted on one side of the base;

[0006] A power assembly, the power device is fixedly mounted on the top surface of the operating platform, and the power assembly is used to drive the grinding wheel to be inspected to rotate;

[0007] A fixing assembly, which is mounted on one side of the support plate and is used to fix the grinding wheel to be tested;

[0008] A detection component is installed on the top surface of the base, and is used to detect whether the grinding wheel to be tested is qualified.

[0009] Preferably, the power assembly includes two first fixed blocks fixedly mounted on the operating platform, a contact wheel is rotatably mounted between the two first fixed blocks, and a drive motor is fixedly mounted on one end of the contact wheel.

[0010] Preferably, the fixing assembly includes two second fixing blocks fixedly mounted on the support plate, a first screw rod is rotatably mounted between the two second fixing blocks, a handle is fixedly mounted on one end of the first screw rod, two sliders are threadedly connected to the first screw rod, a sliding groove is provided on the support plate, the two sliders are respectively slidably mounted on both sides of the sliding groove, and a shell is fixedly mounted on both sliders.

[0011] Preferably, a contact plate is movably installed inside the two shells, and a second return spring is fixedly installed inside the two shells, one end of the second return spring is fixedly installed on the top surface of the shell, and the other end of the second return spring is fixedly installed on one side of the contact plate, and two fixed columns are fixedly installed on the other side of the contact plate, and the two fixed columns are slidably installed with a sleeve rod, and the surfaces of the two sleeve rods are sleeved with a first return spring, and the ends of the two sleeve rods away from the fixed columns are fixedly installed on one side of the connecting plate, and a roller is rotatably installed on one side of the connecting plate.

[0012] Preferably, the detection component includes four support columns fixedly mounted on the base, two of the support columns are installed with fixed sleeves in a direction parallel to the support plate, and the other two support columns are also installed with a fixed sleeve in a direction parallel to the support plate, a sliding roller is slidably mounted in the middle of the two fixed sleeves, a pulley is slidably mounted on the sliding roller, and a motor is installed at one end of the fixed sleeve close to the support plate.

[0013] Preferably, a second screw rod is rotatably installed inside the two fixed sleeves, and a moving block is threadedly connected to the two second screw rods. One end of the two moving blocks is fixedly connected to the sliding roller, and one end of the second screw rod close to the support plate is fixedly connected to the output end of the motor.

[0014] Preferably, a trapezoidal groove is provided on a side of the operating platform close to the detection component, and the trapezoidal groove is located directly below the pulley.

[0015] Beneficial effects of the utility model:

[0016] 1. This type of grinding wheel balancing detection device is provided with a fixed component. After the staff places the grinding wheel to be tested on the operating platform, they drive the first screw to rotate by turning the handle. Since the threads on the screw are relatively arranged, when the screw rotates, the two sliders will move closer to the center along the slide groove, thereby driving the connected shells and internal mechanisms to move inward together. During this process, the grinding wheel first contacts the roller. As the shell gets closer, the roller is squeezed upward, causing the first return spring on the sleeve rod to be compressed and deformed, and the sleeve rod slides upward along the fixed column. If the force applied by the grinding wheel exceeds the elastic limit of the first return spring, the second return spring will start to work and further contract to absorb the additional impact force, ensuring that the grinding wheel is safely and firmly clamped in the fixed component. This process fully demonstrates the flexibility and reliability of the fixed component, and provides a solid foundation for subsequent grinding wheel balancing detection.

[0017] 2. This type of grinding wheel balance detection device for a grinding machine is equipped with a detection component. During the rotation of the grinding wheel, if there is an imbalance problem with the grinding wheel, its rotation will no longer be smooth, thereby generating periodic vibrations. This vibration will directly act on the pulley, causing the pulley to swing left and right on the sliding roller. As the rotation speed of the grinding wheel increases and the degree of imbalance intensifies, the swing amplitude of the pulley will also increase accordingly, until its edge occasionally hits the preset trapezoidal groove. The sound produced by the collision is an intuitive feedback of the imbalance state of the grinding wheel, and also sends a warning signal to the staff, indicating that the grinding wheel has quality problems and needs further processing or replacement.

[0028] like Figures 1 to 5As shown, the grinding wheel balancing detection device for a grinding machine includes: a base 1, a support plate 2 and an operating platform 3 are installed on one side of the base 1; a power component, a power device is fixedly installed on the top surface of the operating platform 3, and the power component is used to drive the grinding wheel to be detected to rotate; a fixing component, a fixing component is installed on one side of the support plate 2, and the fixing component is used to fix the grinding wheel to be detected; a detection component, a detection component is installed on the top surface of the base 1, and the detection component is used to detect whether the grinding wheel to be detected is qualified, and the power component includes two first fixed blocks 4 fixedly installed on the operating platform 3, a contact wheel 5 is rotatably installed between the two first fixed blocks 4, and a drive motor 6 is fixedly installed on one end of the contact wheel 5, and the drive motor 6 is installed on one side of the first fixed block 4, and the output end of the drive motor 6 is fixedly connected to the contact wheel 5;

[0029] First, the staff places the grinding wheel to be tested on the designated position of the operating platform 3. This platform is designed to be stable and can bear the weight of the grinding wheel and provide stable support. Once the grinding wheel is properly placed, the fixing component is started immediately. The fixing component is located on one side of the support plate 2. By rotating the fixing component, it will quickly and evenly move toward the center of the grinding wheel, thereby firmly fixing the grinding wheel in the predetermined position. This process ensures the stability and safety of the grinding wheel in subsequent inspections. Then, the power component is activated. The power component is fixedly installed on the top surface of the operating platform 3. After receiving the start command, the drive motor 6 starts to run and drives the grinding wheel to rotate at a preset speed. This rotation process simulates the dynamic state of the grinding wheel in actual work and provides the necessary conditions for subsequent inspections. At the same time, the detection component begins to enter the working state. The detection component is installed on the top surface of the base 1. The grinding wheel is judged to be qualified by checking whether the grinding wheel will vibrate and displace during rotation and hit the table. The staff will eliminate unqualified grinding wheels to ensure the stability and reliability of the grinding wheel in subsequent processing.

[0030] like Figure 1 、 Figure 2As shown, the fixing assembly includes two second fixing blocks 15 fixedly mounted on the support plate 2, a first screw rod 16 is rotatably mounted between the two second fixing blocks 15, one end of the first screw rod 16 is fixedly mounted with a handle 17, and two sliders 14 are threadedly connected to the first screw rod 16, a slide groove 13 is provided on the support plate 2, and the two sliders 14 are slidably mounted on both sides of the slide groove 13, a housing 18 is fixedly mounted on the two sliders 14, a contact plate 24 is movably mounted inside the two housings 18, a second return spring 25 is fixedly mounted inside the two housings 18, one end of the second return spring 25 is fixedly mounted on the top surface of the housing 18, the other end of the second return spring 25 is fixedly mounted on one side of the contact plate 24, and two fixing columns 23 are fixedly mounted on the other side of the contact plate 24, and a sleeve rod 22 is slidably mounted on the two fixing columns 23, and the surfaces of the two sleeve rods 22 are sleeved with a first return spring 19, and one end of the two sleeve rods 22 away from the fixing column 23 is fixedly mounted on one side of the connecting plate 20, and a roller 21 is rotatably mounted on one side of the connecting plate 20;

[0031] The fixing assembly mainly consists of two second fixed blocks 15 firmly mounted on the support plate 2, between which a first screw rod 16 is rotatably mounted, the threads on the first screw rod 16 are arranged relative to each other, and one end of the first screw rod 16 is fixedly connected to a handle 17 for easy operation, so that the staff can easily rotate the screw rod, and two sliders 14 are symmetrically rotatably mounted on the first screw rod 16. The two sliders 14 slide and are embedded in the pre-cut grooves 13 on the support plate 2, so that the sliders 14 can move smoothly along the grooves 13. Each slider 14 is fixedly mounted with a shell 18, and an elastic mechanism is provided inside the shell 18 to adapt to grinding wheels of different sizes. A second return spring 25 is fixedly mounted at one end of the shell 18, and the other end is connected to a contact plate 24. Two fixed columns 23 are fixedly mounted on the other side of the contact plate 24, and a sleeve rod 22 is slidably mounted on the two fixed columns 23. The outer surface of the sleeve rod 22 is provided with a first return spring 19, which provides initial elastic support for the sleeve rod 22 and allows it to expand and contract when subjected to external force. The sleeve rod 22 is away from the fixed column 23. The end is fixedly connected to the connecting plate 20, and a roller 21 is rotatably installed on one side of the connecting plate 20 for initial contact and guiding the grinding wheel into a fixed position. When the staff places the grinding wheel to be tested on the operating platform 3, they drive the first screw 16 to rotate by turning the handle 17. Since the threads on the screw are relatively arranged, when the screw rotates, the two sliders 14 will move toward the center along the slide groove 13, thereby driving the housing 18 and the internal mechanism connected to each other to move inward together. In this process, the grinding wheel first contacts the roller 21. As the housing 18 gets closer, the roller 21 is squeezed upward, causing the first return spring 19 on the sleeve rod 22 to be compressed and deformed, and the sleeve rod 22 slides upward along the fixed column 23. If the force applied by the grinding wheel exceeds the elastic limit of the first return spring 19, the second return spring 25 will start to work and further contract to absorb the additional impact force, ensuring that the grinding wheel is safely and firmly clamped in the fixed assembly. This process fully demonstrates the flexibility and reliability of the fixed assembly, providing a solid foundation for subsequent grinding wheel balancing detection.

[0032] like Figure 3 、 Figure 4 、 Figure 5As shown, the detection assembly includes four support columns 7 fixedly mounted on the base 1, two support columns 7 are installed with fixed sleeves 8 in a direction parallel to the support plate 2, and the other two support columns 7 are also installed with a fixed sleeve 8 in a direction parallel to the support plate 2, a sliding roller 9 is slidably installed in the middle of the two fixed sleeves 8, a pulley 10 is slidably installed on the sliding roller 9, and a motor 11 is installed at one end of the fixed sleeve 8 close to the side of the support plate 2, and a second screw rod 27 is rotatably installed inside the two fixed sleeves 8, and the two second screw rods 27 are threadedly connected to a moving block 28, one end of the two moving blocks 28 is fixedly connected to the sliding roller 9, and one end of the second screw rod 27 close to the support plate 2 is fixedly connected to the output end of the motor 11, and a trapezoidal groove 12 is provided on the side of the operating platform 3 close to the detection assembly, and the trapezoidal groove 12 is located directly below the pulley 10;

[0033] During the inspection process, the staff first starts the motor 11 at the end of the fixed sleeve 8 near one side of the support plate 2. The motor 11 serves as a power source and is connected to the second screw rod 27 near the support plate 2 through its output end to drive the screw rod to rotate. Since the second screw rod 27 is installed inside the two fixed sleeves 8, and the two screw rods are rotatably connected to the moving block 28, one end of the two moving blocks 28 is fixedly connected to the sliding roller 9, so when the second screw rod 27 rotates, it will drive the sliding roller 9 to slide horizontally between the fixed sleeves 8. The sliding adjustment of the sliding roller 9 directly determines the position of the pulley 10 thereon, so that it can be accurately clamped and positioned according to the actual size of the grinding wheel to ensure that the grinding wheel is firmly and evenly clamped. Subsequently, the staff starts the drive motor 6, and the drive motor 6 drives the contact wheel 5 that is in contact with the grinding wheel part to start rotating. Since the grinding wheel has been moved by the pulley 10, etc. The device is clamped and keeps in contact with the rotating component contact wheel 5, so when the rotating component contact wheel 5 rotates, it will drive the grinding wheel to rotate synchronously. This step simulates the rotation state of the grinding wheel in actual work and provides the necessary dynamic conditions for subsequent imbalance detection. During the rotation of the grinding wheel, if there is an imbalance problem with the grinding wheel, its rotation will no longer be smooth, thereby generating periodic vibrations. This vibration will directly act on the pulley 10, causing the pulley 10 to swing left and right on the sliding roller 9. As the grinding wheel rotates faster and the imbalance degree intensifies, the swing amplitude of the pulley 10 will also increase accordingly until its edge hits the preset trapezoidal groove 12 from time to time. The sound produced by the collision is an intuitive feedback on the imbalance state of the grinding wheel, and also sends a warning signal to the staff, indicating that the grinding wheel has quality problems and needs further processing or replacement.
