Description

Technical Field

[0001] The invention belongs to the technical field of grinding wheel balance detection, and in particular relates to a balance detection device and method for grinding wheel processing. Background Art

[0002] Grinding wheels are the most important type of abrasive tools in grinding. Grinding wheels are porous bodies made by adding a binder to abrasives, pressing, drying and sintering. During the manufacturing process of grinding wheels, technical problems and manufacturing errors lead to uneven distribution of grinding wheel particle mass, which causes the center of the grinding wheel and the center of rotation to not coincide, and eccentric shaking is easy to occur during rotation, affecting normal use. Therefore, after the grinding wheel is manufactured, it is necessary to perform dynamic balancing detection on it to avoid vibration of the grinding wheel when it rotates at high speed.

[0003] The existing patent application number "CN 107367352 A" proposes a grinding wheel balance detection device, which records that "during the start-up process of the grinding wheel motor, the balance detection device detects the vibration generated by the grinding wheel in real time, and sends a vibration detection signal to the control module. When the vibration detection signal is greater than the safety range value, the control module controls the servo motor to turn off, so that the grinding wheel frame cannot feed the workpiece; when the vibration detection signal is within the safety range value, the control module controls the servo motor to start, and can control the grinding wheel frame to feed the workpiece by a set processing distance, thereby grinding the workpiece to avoid the vibration generated by the grinding wheel affecting the processing quality of the workpiece, and avoid shortening the life of parts such as bearings connected to the grinding wheel, thereby increasing maintenance costs." The above application can quickly know whether the grinding wheel has reached a speed balance and reduce unnecessary waiting time. However, during the grinding wheel detection process, the grinding wheel detection device itself may be damaged due to the grinding wheel vibration, affecting the service life of the detection device. At the same time, it is not possible to detect and classify repairable and non-repairable grinding wheels.

[0004] In the prior art, the grinding wheel detection device may cause damage to the detection device itself due to the rotational vibration of the grinding wheel when detecting the balance of the grinding wheel. At the same time, the detection of good and defective grinding wheels cannot be accurately classified. Therefore, we propose a balance detection device and method for grinding wheel processing. Summary of the invention

[0005] The purpose of the present invention is to provide a balance detection device and method for grinding wheel processing, so as to solve the problem that the existing grinding wheel detection device may cause damage to the detection device itself due to the rotation vibration of the grinding wheel when detecting the balance of the grinding wheel, and at the same time, it is impossible to accurately classify the detection of good and defective grinding wheels.

[0015] Preferably, a fixing part is welded to a side of the shell away from the clamping assembly, the back of the fixing part is fixedly connected to the output end of the motor, and the back of the motor is fixedly installed on a side of the control box; a power-off switch is fixedly connected to the inner wall of the fixing part, the power-off switch is located on the central axis of the central axis, and one end of the central axis is in active contact with the power-off switch.

[0016] Preferably, the infrared component includes a slide rail, which is welded to the center position of the top of the rack, and a slide seat is movably connected to the slide rail. Lifting rods are fixedly connected to the opposite ends of the top of the slide seat, and an infrared transmitter is fixedly installed on the left lifting rod, and an infrared receiver is fixedly installed on the right lifting rod.

[0017] A detection method of a balance detection device for grinding wheel machining comprises the following steps:

[0018] S1. Hold the grinding wheel and place the inner ring of the grinding wheel outside the four clamping blocks. Start the rotating motor through the control panel with one hand and hold the mounting plate with the other hand to press the pulley. The rotating motor drives the screw to rotate and drives the pulley to move to the right on the screw surface. The distance between the pulley and the mounting plate gradually shortens, and the angle between the support arm and the sliding arm gradually decreases until the four clamping blocks contact the surface of the inner ring of the grinding wheel to fix the grinding wheel. At this time, the telescopic rod is fully extended and retracted inside the sleeve, and the two ends of the fixing rod are aligned with the left clamping block and the right clamping block for clamping and fixing;

[0019] S2. Manually move the slide on the slide rail until the infrared transmitter and infrared receiver on the left and right sides of the top of the slide are located on both sides of the grinding wheel. Adjust the height of the lifting rod according to the size of the grinding wheel to ensure that the lowest point of the grinding wheel is close to the infrared light emitted by the infrared transmitter when the grinding wheel is in a stationary state, and the distance between the infrared light and the lowest point of the grinding wheel is no more than 0.1CM, so as to ensure that the infrared light emitted by the infrared transmitter when the grinding wheel is in a stationary state can be received by the infrared receiver and is not blocked by the grinding wheel;

[0020] S3. Start the motor through the control panel, and the motor drives the detection component to rotate, thereby driving the grinding wheel fixed on the clamping component to rotate. If there is a grinding wheel with quality problems, the grinding wheel will vibrate during rotation. The vibration sensor monitors the vibration data, and the display device on the control box displays the vibration data. The larger the vibration data, the more serious the quality problem of the grinding wheel, and vice versa. At the same time, when the grinding wheel rotates, the infrared transmitter below transmits infrared light to the infrared receiver on the other side. If the infrared receiver cannot receive the infrared light emitted by the infrared transmitter at a certain moment, it indicates that the grinding wheel rotates eccentrically, and its lowest point contacts the infrared light, blocking the infrared receiver from receiving the infrared light, and determining that the center of the grinding wheel does not coincide with the center of rotation;

[0021] S4. While the grinding wheel rotates, the vibration generated is transmitted to the detection component. The movable ring in the detection component moves back and forth on the central axis through the first spring. If the vibration amplitude is too large, the top block at the front end of the connecting rod will push the blocking block toward the second spring, and the wedge block is no longer blocked by the blocking block. Under the reset action of the third spring in the stretched state, the central axis quickly moves toward the power-off switch until one end of the central axis hits the power-off switch. The power-off switch cuts off the power to the motor, and the detection component, the clamping component and the grinding wheel stop rotating. At the same time, when the central axis moves to the left, the telescopic rod extends from the sleeve, and the pulley moves to the left away from the mounting plate. The angle between the support arm and the sliding arm becomes larger, and the four clamping blocks no longer clamp the grinding wheel, indicating that the center of the grinding wheel is seriously misaligned with the rotation center and there is no need for repair. It is a defective product, and the grinding wheel balance detection is stopped.

[0022] Preferably, step S1 also includes the following steps: adjusting the position of the vibration sensor on the surface of the fixed rod through a slider according to the detection standard, wherein the higher the detection standard, the closer the vibration sensor is to the grinding wheel, and conversely, the lower the detection standard, the farther the vibration sensor is from the grinding wheel.

[0023] The present invention has the following beneficial effects:

[0024] 1. The present invention sets a movable vibration monitoring component and sets the vibration sensor on a detachable fixed rod. According to the detection standard of the grinding wheel, if the detection standard of the grinding wheel is high, the vibration sensor is moved to a position closer to the grinding wheel through a slider, because the closer the distance to the grinding wheel, the greater the received vibration intensity. When the vibration data exceeds a preset range, it means that there is a problem with the balance state of the grinding wheel. According to the detection of the subsequent detection device, it is judged whether the grinding wheel needs to be repaired. If the detection standard of the grinding wheel is low, the vibration sensor is moved to a position farther from the grinding wheel through a slider, because the farther the distance to the grinding wheel, the smaller the received vibration intensity. According to the preset vibration data, it is determined whether the grinding wheel has a balance problem.

[0025] 2. The present invention sets a clamping assembly, and drives the screw rod to rotate through a rotating motor, thereby driving the pulley threadedly connected to the surface of the screw rod to move left and right on its surface, changing the distance between the pulley and the mounting plate, thereby changing the angle between the support arm and the sliding arm. The smaller the angle, the larger the clamping radius, and the smaller the angle, the smaller the clamping radius, thereby adapting to the clamping and fixing of grinding wheels of different sizes, and setting a telescopic rod and a sleeve between the mounting plate and the pulley. When the vibration amplitude of the grinding wheel is too large during rotation, the central axis in the detection assembly moves left, driving the rotating motor and the screw rod to move left. Since the pulley is set on the surface of the screw rod, the pulley drives the sliding arm fixed on its surface to move left at the same time. At this time, the telescopic rod extends out of the sleeve, the distance between the mounting plate and the pulley increases, the angle between the support arm and the sliding arm increases, thereby the clamping radius decreases, the grinding wheel is loosened during the clamping process, and the grinding wheel is stopped from continuing to move on the detection device, thereby avoiding damage to the detection device due to its excessive rotation vibration amplitude.

[0026] 3. The present invention detects whether the grinding wheel needs to be repaired by setting a detection device, and also provides extreme protection for the detection device to avoid damage to the device due to excessive vibration of the grinding wheel. The vibration generated during the rotation of the grinding wheel is captured by the movable ring, and the movable ring continuously slides left and right on the surface of the central axis, while driving the connecting rod connected to it to slide inside the outer shell. When the vibration amplitude exceeds the safe range that the device can withstand, the top block pushes toward the inside of the blocking block, causing the blocking block to move in the direction of the second spring, thereby releasing the blocking of the wedge block. Under the action of the third spring, the central axis moves to the left and contacts the power-off switch. The power-off switch disconnects the motor, causing the detection component to stop rotating. BRIEF DESCRIPTION OF THE DRAWINGS

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] See also Figure 1-13The present invention is a balance detection device for grinding wheel processing, comprising a frame 1, on which a vibration monitoring component, a clamping component and a detection component are sequentially installed from right to left, and an infrared component is installed on the top of the frame 1 below the clamping component. The frame 1 is used as the main component of the detection device and is used to carry various structural components installed therein;

[0047] The clamping assembly includes a mounting plate 11, one side of the mounting plate 11 is fixedly connected with a sleeve 20, a telescopic rod 21 is movably sleeved inside the sleeve 20, one end of the telescopic rod 21 is movably connected to one end of a screw rod 22, a pulley 17 is sleeved on the side surface of the screw rod 22, the mounting plate 11 is used to install and connect four support arms 13 connected in an array on its side surface through a first movable member 12, one end of the support arm 13 is driven to rotate by the first movable member 12, the telescopic rod 21 is used to sleeve with the inside of the sleeve 20, the telescopic rod 21 and the sleeve 20 are used to increase the distance between the mounting plate 11 and the pulley 17 when the central axis 24 moves to the left, and the distance between the two can be increased to clamp the four fixed grinding wheels 44 The block 19 relaxes, so that the grinding wheel 44 is separated from the clamping assembly, and the detection is stopped to avoid damage to the detection assembly. The screw rod 22 rotates under the drive of the rotary motor 23, thereby driving the pulley 17 to slide left and right on its surface, so as to control the clamping assembly to clamp the grinding wheel 44. It should be noted that when clamping the grinding wheel 44, one hand is required to hold the mounting plate 11 and press in the direction of the pulley 17 to ensure that when the rotary motor 23 drives the screw rod 22 to rotate, the entire clamping assembly is not driven to rotate. When the pulley 17 moves to the left on the surface of the screw rod 22, the grinding wheel 44 is loosened, and when the pulley 17 moves to the right on the surface of the screw rod 22, the grinding wheel 44 is clamped and clamped;

[0048] The detection assembly includes a central shaft 24, the right end of which is connected to the clamping assembly. A wedge block 33 is fixedly sleeved on the central shaft 24, and blocking blocks 31 are movably connected to the upper and lower ends of the wedge block 33. The central shaft 24 serves as an axis connecting the clamping assembly. Through the elastic force of the third spring 34, the central shaft 24 does not contact the power-off switch 37 when there is no power failure. When the wedge block 33 on the surface of the central shaft 24 is no longer blocked by the upper and lower blocking blocks 31, the third spring 34 is no longer stretched and begins to reset to the left, thereby The central shaft 24 is driven to move to the left, and the telescopic rod 21 in the clamping assembly is pulled out of the sleeve 20, so that the clamping assembly stops clamping the grinding wheel 44. One side of the wedge block 33 is an inclined surface, and the other side is a vertical surface. When there is no power failure, the blocking block 31 presses against one side of the vertical surface of the wedge block 33 to prevent the central shaft 24 from moving. When the blocking block 31 is subjected to the force on both sides and moves toward the second spring 32, the blocking block 31 no longer blocks the wedge block 33, and the central shaft 24 slides to the left through the reset force of the third spring 34.

[0049] Among them, a base 2 is welded at each corner position of the bottom of the frame 1, a control box 3 and a control console 4 are fixedly installed on the top of the frame 1, the control console 4 is fixedly connected to the center position of one side of the top of the frame 1, the control box 3 is fixedly installed at the left position of the top of the frame 1, the control box 3 is fixedly connected to the detection component, the base 2 is used to support the entire device, a display device is provided on the surface of the control box 3, which is used to display the infrared data detected by the infrared component during the detection process, and the vibration data transmitted by the vibration sensor, and the control console 4 is used to control the operation of the entire device.

[0050] Among them, the vibration detection component includes a right clamping block 5, one side of the right clamping block 5 is welded to a side surface of the frame 1, and the other side of the right clamping block 5 is clamped with one end of the fixed rod 6. A slide groove is provided on the top of the fixed rod 6, and a slider 7 is movably arranged inside the slide groove. A vibration sensor 8 is installed on the top of the slider 7. The right clamping block 5 and the left clamping block 9 are both used to clamp and fix the fixed rod 6. Since the length of the fixed rod 6 is fixed, when the fixed rod 6 is clamped on the device, the mounting plate 11 needs to be pressed to the left so that the telescopic rod 21 is completely retracted inside the sleeve 20.

[0051] The clamping assembly further comprises a left clamping block 9, one end of which is clamped with one end of the fixing rod 6, the other end of which is movably connected with the rotating shaft 10, the other end of which is welded with the outer side of the mounting plate 11, and four first movable members 12 are connected in an array around the side of the mounting plate 11, each of which is fixedly connected with one end of the support arm 13, the other end of the support arm 13 is movably arranged on the sliding arm 15 through a pin 14, one end of the sliding arm 15 is movably connected with the clamping block 19 through a third movable member 18, and the other end of the sliding arm 15 is arranged on the side of the pulley 17 through a second movable member 16, and the side of the pulley 17 is connected to the The four second movable parts 16 are fixedly connected; the end of the screw rod 22 away from the telescopic rod 21 is fixedly connected to the output end of the rotary motor 23, and the rotary motor 23 is fixedly installed at one end of the central axis 24. The rotary shaft 10 is used to connect the left clamping block 9 and the mounting plate 11, so that the clamping assembly can still be connected to the right vibration detection assembly when it rotates. During the mutual movement of the support arm 13 and the sliding arm 15, the larger the angle between them, the larger the size of the inner ring of the fixed grinding wheel 44, and the smaller the angle between them, the smaller the size of the inner ring of the fixed grinding wheel 44, so as to adapt to grinding wheels of different sizes. The clamping block 19 is used to clamp the inner ring of the grinding wheel 44.

[0052] The detection assembly further comprises a movable ring 25, which is movably sleeved on the side surface of the central shaft 24, and the central shaft 24 passes through the shell 35 to the outside thereof. One side surface of the shell 35 is connected to one end of a first spring 27, and the other end of the first spring 27 is fixedly connected to one side surface of the movable ring 25.

When a problematic grinding wheel 44 appears, it will inevitably generate vibration due to the misalignment of its center with the rotation center during rotation. Therefore, under the action of the first spring 27, the movable ring 25 slides back and forth on the surface of the central axis 24. At the same time, the connecting rod 29 connected to the movable ring 25 through the connecting block 28 slides back and forth inside the housing 35 with the movable ring 25. When the vibration amplitude is too large, the top block 30 at the front end of the connecting rod 29 continuously pushes toward the inside of the blocking block 31, so that the blocking block 31 moves toward the direction of the second spring 32, resulting in the blocking block 31 no longer blocking the wedge block 33. At this time, under the action of the third spring 34, the central axis 24 moves to the left.

[0053] Among them, a connecting block 28 is welded at the upper and lower ends of the outer surface of the movable ring 25, and the connecting block 28 is fixedly connected to one end of the connecting rod 29. The other end of the connecting rod 29 is movably arranged inside the shell 35 and fixedly connected to the top block 30. One side of the top block 30 is an inclined surface, and its inclined surface part is movably arranged inside the blocking block 31. The blocking block 31 is provided with a movable groove near the top block 30. The bottom wall of the movable groove is an inclined surface. The inclined surface of the top block 30 contacts and slides with the inclined surface of the bottom wall of the movable groove. The blocking block 31 is movably arranged inside the shell 35.

[0054] Among them, a fixing part 36 is welded on the side of the shell 35 away from the clamping assembly, the back of the fixing part 36 is fixedly connected to the output end of the motor 38, and the back of the motor 38 is fixedly installed on a side of the control box 3; a power-off switch 37 is fixedly connected to the inner wall of the fixing part 36, the power-off switch 37 is located on the central axis of the central shaft 24, and one end of the central shaft 24 is in movably contact with the power-off switch 37.

[0055] Among them, the infrared component includes a slide rail 39, which is welded to the center position of the top of the frame 1. A slide seat 40 is movably connected to the slide rail 39. Lifting rods 41 are fixedly connected to the opposite ends of the top of the slide seat 40. An infrared transmitter 42 is fixedly installed on the left lifting rod 41, and an infrared receiver is fixedly installed on the right lifting rod 41.

[0056] A detection method of a balance detection device for grinding wheel machining comprises the following steps:

[0057] S1. Hold the grinding wheel 44 and place the inner ring of the grinding wheel 44 outside the four clamping blocks 19. Start the rotating motor 23 through the control console 4 with one hand and hold the mounting plate 11 with the other hand to press the pulley 17. The rotating motor 23 drives the screw rod 22 to rotate and drives the pulley 17 to move rightward on the surface of the screw rod 22. The distance between the pulley 17 and the mounting plate 11 is gradually shortened, and the angle between the support arm 13 and the sliding arm 15 is gradually reduced until the four clamping blocks 19 are in contact with the inner ring surface of the grinding wheel 44 to fix the grinding wheel 44. At this time, the telescopic rod 21 is completely retracted inside the sleeve 20, and the two ends of the fixing rod 6 are aligned with the left clamping block 9 and the right clamping block 5 for clamping and fixing;

[0058] S2. Manually move the slide 40 on the slide rail 39 until the infrared transmitter 42 and the infrared receiver 43 on the left and right sides of the top of the slide 40 are located on both sides of the grinding wheel 44. The height of the lifting rod 41 is adjusted according to the size of the grinding wheel 44 to ensure that the lowest point of the grinding wheel 44 is close to the infrared light emitted by the infrared transmitter 42 when the grinding wheel 44 is in a stationary state, wherein the distance between the infrared light and the lowest point of the grinding wheel 44 is no more than 0.1CM, to ensure that the infrared light emitted by the infrared transmitter 42 when the grinding wheel 44 is in a stationary state can be received by the infrared receiver 43 and is not blocked by the grinding wheel 44;

[0059] S3, start the motor 38 through the control console 4, the motor 38 drives the detection component to rotate, thereby driving the grinding wheel 44 fixed on the clamping component to rotate. If there is a grinding wheel 44 with quality problems, the grinding wheel 44 will vibrate during rotation, the vibration sensor 8 monitors the vibration data, and the display device on the control box 3 displays the vibration data. The larger the vibration data, the more serious the quality problem of the grinding wheel 44, and vice versa. At the same time, when the grinding wheel 44 rotates, the infrared transmitter 42 below transmits infrared light to the infrared receiver 43 on the other side. If the infrared receiver 43 does not receive the infrared light emitted by the infrared transmitter 42 at a certain moment, it indicates that the grinding wheel 44 rotates eccentrically, and its lowest point contacts the infrared light, blocking the infrared receiver 43 from receiving the infrared light, and determining that the center of the grinding wheel 44 does not coincide with the rotation center;

[0060] S4, while the grinding wheel 44 rotates, the vibration generated is transmitted to the detection component. The movable ring 25 in the detection component moves back and forth on the central shaft 24 through the first spring 27. If the vibration amplitude is too large, the top block 30 at the front end of the connecting rod 29 pushes the blocking block 31 toward the second spring 32, and the wedge block 33 is no longer blocked by the blocking block 31. Under the reset action of the third spring 34 in the stretched state, the central shaft 24 quickly moves toward the power-off switch 37 until one end of the central shaft 24 hits the power-off switch. When the switch 37 is turned on, the power-off switch 37 cuts off the power to the motor 38, and the detection assembly, the clamping assembly and the grinding wheel 44 stop rotating. At the same time, when the central axis 24 moves to the left, the telescopic rod 21 extends from the sleeve 20, and the pulley 17 moves to the left away from the mounting plate 11. The angle between the support arm 13 and the sliding arm 15 becomes larger, and the four clamping blocks 19 no longer clamp the grinding wheel 44, indicating that the center of the grinding wheel 44 is seriously misaligned with the rotation center, and there is no need to repair it. It is a defective product, and the balance detection of the grinding wheel 44 is stopped.

[0061] Among them, step S1 also includes the following steps: adjusting the position of the vibration sensor 8 on the surface of the fixed rod 6 through the slider 7 according to the detection standard, wherein the higher the detection standard, the closer the vibration sensor 8 is to the grinding wheel 44, and conversely, the lower the detection standard, the farther the vibration sensor 8 is from the grinding wheel 44.
