Description

Technical Field

[0001] This application relates to the field of thickness detection technology, and in particular to an automatic detection device for grinding wheel thickness. Background Technology

[0002] As a core consumable in grinding processes, the thickness and wear of grinding wheels directly determine the machining accuracy and quality of workpieces. Therefore, regular and efficient inspection of grinding wheel thickness is a crucial step in the manufacturing industry.

[0003] Currently, the detection of grinding wheel thickness mostly relies on manual inspection. Operators use tools such as calipers or dial indicators for offline measurement. This method is not only cumbersome and inefficient, but the accuracy of the measurement results is also greatly affected by the operator's skill level and subjective factors, making it difficult to guarantee the consistency and reliability of the test data. Utility Model Content

[0004] To improve the problem of cumbersome and inefficient manual inspection, this application provides an automatic detection device for grinding wheel thickness.

[0005] The automatic grinding wheel thickness detection device provided in this application adopts the following technical solution:

[0006] An automatic grinding wheel thickness detection device includes a base, a water spray pipe fixed on one side of the base, a driving device fixed on the bottom of the base, a clamping device at the bottom of the driving device, a grinding wheel body inside the clamping device, a measuring mechanism for automatically detecting the thickness of the grinding wheel body on the outer surface of the driving device, and a roller that abuts against the bottom surface of the grinding wheel body rotatably at the output end of the measuring mechanism.

[0007] By adopting the above technical solution, the base, as the fundamental support component of the entire automatic grinding wheel thickness detection device, provides a stable mounting platform for other components, ensuring the stability and reliability of the overall structure of the device. This allows the entire detection device to maintain a relatively stable position during operation, reducing interference with the detection results caused by factors such as shaking. The water spray pipe sprays coolant (water or special grinding fluid) onto the grinding area between the grinding wheel and the workpiece to achieve multiple functions such as cooling (preventing workpiece burning and grinding wheel thermal damage), lubrication (reducing friction and improving surface quality), cleaning (washing away grinding debris and preventing grinding wheel clogging), and rust prevention. It is a key component to ensure the normal operation of the grinding process. The drive device provides precise rotational motion, driving the clamping device and the grinding wheel body on it to rotate. It is the power core for realizing the normal grinding function of the grinding wheel and performing thickness circumferential scanning measurement. The clamping device is used to accurately and reliably clamp and fix the grinding wheel body, ensuring that the grinding wheel will not loosen or shift during high-speed rotation and inspection, thus guaranteeing machining safety and the stability of the measurement reference. The grinding wheel body is the object being inspected and also the tool for grinding. The measuring mechanism integrates multiple functions such as driving, transmission, sensing, display, and recording. It is responsible for moving the roller along the bottom surface of the grinding wheel under the drive of the drive device, sensing the thickness change, and converting the physical displacement into a visual reading or record, thus achieving the core purpose of automatic thickness detection. The roller is the detection element that directly contacts the bottom surface of the grinding wheel. Its function is to roll in the measurement mode, accurately converting the contour height (i.e., thickness change) of the bottom surface of the grinding wheel into its own vertical displacement, and transmitting this displacement to the measuring mechanism. The roller structure can reduce friction and wear between the roller and the grinding wheel, ensuring smooth movement and measurement accuracy.

[0008] Preferably, the measuring mechanism includes a track, an auxiliary frame is slidably connected inside the track, a driving component is provided on one side of the auxiliary frame, and a cylinder is fixedly provided inside the driving component.

[0009] By adopting the above technical solution, the track provides a precise, circular motion path reference for the entire measuring mechanism, ensuring that the auxiliary frame and all its internal components can perform stable and smooth circular motion around the grinding wheel spindle, completing the scanning measurement of the entire circumferential thickness of the grinding wheel. The auxiliary frame, as the core frame and motion carrier of the measuring mechanism, slides along the track under the drive component. At the same time, it houses and supports all measurement-related components such as sliders, springs, and connecting plates, forming an independent measuring unit. The drive component provides precise and controllable power for the auxiliary frame and its entire internal measuring system to perform circular motion along the track, realizing automated scanning and detection. The cylinder acts as a precise guide shaft, constraining the slider to slide up and down only along its axial direction (i.e., the vertical direction), and preventing horizontal offset or torsion, ensuring that the slider's movement strictly responds to the grinding wheel thickness change sensed by the roller.

[0010] Preferably, a slider is slidably connected to the outer surface of the cylinder, a fixed cylinder is symmetrically fixed to the top surface of the slider, a movable column is fixedly fixed inside the fixed cylinder, and a return spring is fixedly sleeved on the outer surface of the fixed cylinder and the movable column between the top surface of the slider and the auxiliary frame.

[0011] By adopting the above technical solution, the slider is the "motion conversion core" of the entire measuring mechanism. It is connected to the roller through the connecting plate, accurately transmitting the vertical displacement of the roller to itself. At the same time, its own vertical movement along the cylinder directly drives the pointer and marker, realizing the key function of converting the physical thickness signal into a visual signal. Fixed cylinder one and moving column one form an internal guiding mechanism. The function of return spring one is to continuously apply elastic force downward, working together with the return spring two below to form a "floating" clamping force. This force ensures that the roller can always be pressed tightly against the bottom surface of the grinding wheel with constant and appropriate pressure, following its contour changes, avoiding contact loss due to vibration or inertia, thereby ensuring the continuity and reliability of the measurement.

[0012] Preferably, a fixed cylinder two is symmetrically fixedly arranged on the bottom surface of the slider, a movable column two is fixedly arranged inside the fixed cylinder two, and a reset spring two is fixedly arranged between the bottom surface of the slider and the auxiliary frame, which is sleeved on the outer surface of the fixed cylinder two and the movable column two.

[0013] By adopting the above technical solution, the functions of the fixed cylinder two and the movable column two are to provide additional guidance and limiting support for the slider from the bottom. Together with the upper component, this makes the slider's up-and-down movement more stable and precise. The function of the return spring two is to continuously apply upward elastic force, working in conjunction with the return spring one to maintain elastic support for the slider and constant contact pressure between the roller and the grinding wheel. The dual-spring design improves the system's balance and response sensitivity.

[0014] Preferably, a connecting plate is fixedly provided on one side of the slider and slidably connected inside the auxiliary frame, a fixing plate is fixedly provided on one side of the connecting plate, a movable plate is slidably provided inside the fixing plate, and the bottom of the movable plate is rotatably connected to the roller.

[0015] By adopting the above technical solution, the connecting plate one acts as a "bridge" connecting the slider and the external detection element. Its function is to reliably transmit the up-and-down movement of the slider's core to the fixed plate one and the moving plate, ultimately driving the roller. The fixed plate one is fixed on the connecting plate one, and its main function is to provide an installation reference and sliding guide rail for accommodating and guiding the moving plate to slide horizontally, thereby adjusting the detection position. The moving plate supports the roller and can slide horizontally within the guide rail of the fixed plate one. By changing its position, the radial relative distance between the roller and the grinding wheel spindle can be adjusted to accommodate grinding wheels of different diameters or to adjust the measurement radius.

[0016] Preferably, the fixed plate has a plug-in post inserted inside, and the movable plate has a plug hole 1 and a plug hole 2 inside, which are adapted to the plug-in post.

[0017] By adopting the above technical solution, the insertion pin is a safety locking and quick positioning mechanism. Its function is to reliably lock the moving plate in either the "working (detection) position" or the "avoidance (non-detection) position" by inserting it into different insertion holes (insertion hole one or insertion hole two) on the moving plate. This prevents accidental intervention of the measuring mechanism during grinding and ensures the repeatability accuracy of the position during detection. Insertion holes one and two are used in conjunction with the insertion pin. Insertion hole one corresponds to the "avoidance position" where the roller is away from the grinding wheel, used for normal grinding. Insertion hole two corresponds to the "detection position" where the roller is located at the bottom of the grinding wheel, used for thickness measurement. This achieves rapid and reliable switching between the two working modes of detection and processing.

[0018] Preferably, a pointer is fixedly provided on the outer surface of the slider, and several scale lines are printed on the outer surface of the auxiliary frame.

[0019] By adopting the above technical solution, the pointer moves synchronously with the slider as it moves up and down. Its function is to point to the scale line, displaying the thickness change of the grinding wheel in the most intuitive and real-time way, allowing operators to quickly read the thickness value. The scale line serves as a reference for the pointer's indication. By converting the pointer's displacement into a specific thickness value, quantitative measurement of the thickness is achieved.

[0020] Preferably, a marker is provided on the outer surface of the slider, and an indicator plate is fixedly provided on the outer surface of the auxiliary frame.

[0021] By adopting the above technical solution, the core function of the marker pen is to draw a continuous trajectory line on the indicator plate as the slider moves. This line not only records the thickness of each point on the entire circumference, but also intuitively shows the uniformity of the grinding wheel thickness (a straight line indicates uniformity, and a wavy line indicates non-uniformity), providing richer quality information than single-point measurement. The function of the indicator plate is to work with the marker pen to permanently record the thickness trajectory of the grinding wheel in one revolution, which can be used for post-event review, quality traceability, and wear uniformity analysis.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By utilizing the cooperation between the drive wheel and the track, as well as the synergistic effect of the slider, return spring and other structures, the roller can automatically fit tightly against the bottom of the grinding wheel and rotate one revolution to complete the thickness detection. The entire process does not require manual pushing of the roller or complex measurement operations, thus realizing the automation of the detection process and improving detection efficiency and accuracy.

[0024] 2. By using the reset springs 1 and 2 on the upper and lower parts of the slider to connect with the auxiliary frame, this design ensures that the roller always maintains a stable pressure against the bottom of the grinding wheel. No matter what minor unevenness or vibration exists on the surface of the grinding wheel during rotation, the reset spring can adjust the position and pressure of the roller in time to ensure that the roller always has good contact with the bottom of the grinding wheel, thereby obtaining more accurate thickness measurement data.

[0025] 3. With the pointer and marker on the slider, the pointer can point to the scale line in real time during the movement of the roller, and the marker draws a line on the outer surface of the indicator plate. This intuitive presentation method not only makes it convenient for operators to quickly read the value of the grinding wheel thickness, but also allows them to intuitively judge the uniformity of the grinding wheel thickness and whether there are abnormalities such as local wear by observing the shape and changes of the drawn lines. This provides more comprehensive and accurate information for the quality assessment and maintenance of the grinding wheel. Attached Figure Description

[0036] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0037] This application discloses an automatic detection device for grinding wheel thickness.

[0038] Reference Figure 1 , Figure 2 An automatic grinding wheel thickness detection device includes a base 1, one side of which is fixedly connected to a water spray pipe 2 for cooling the grinding wheel. The bottom of the base 1 is fixedly connected to a drive device 3 for driving the grinding wheel. The drive end of the drive device 3 is fixedly connected to a clamping device 4. The inner wall of the clamping device 4 is fixedly engaged with the grinding wheel body 5. A measuring mechanism 6 is provided on the outer surface of the fixed end of the drive device 3 for automatically detecting the thickness of the grinding wheel body 5. The output end of the measuring mechanism 6 is rotatably connected to a roller 7, and the roller 7 abuts against the bottom surface of the grinding wheel body 5.

[0039] In use, the grinding wheel body 5 is driven to rotate by the drive device 3, thereby grinding the object to be ground. During grinding, water is sprayed onto the grinding wheel body 5 through the water spray pipe 2 to reduce the temperature of the grinding wheel body 5. In addition, the roller 7 can be attached to the bottom edge of the grinding wheel body 5, and the thickness of the grinding wheel body 5 is detected by the measuring mechanism 6.

[0040] Reference Figure 2 , Figure 3The measuring mechanism 6 includes a track 61, which is fixedly connected to the outer surface of the fixed end of the drive device 3. The track 61 has an I-shaped cross-section, and its inner wall is slidably connected to the auxiliary frame 62. The auxiliary frame 62 includes several rollers, which are slidably connected in the groove of the track 61. One of the rollers is driven to rotate by a motor, and its center is rotatably connected to a connecting plate. The connecting plate is located on the side away from the drive device 3, and its side is fixedly connected to the drive assembly 63. The center of the inner wall of the drive assembly 63 is fixedly connected to a cylinder 64.

[0041] In use, one of the rollers is driven to rotate by a motor. The rotation of the roller causes the entire connecting plate to move within the groove of the track 61, thereby allowing the roller 7 to move on the bottom surface of the grinding wheel body 5 for multi-point detection.

[0042] Reference Figure 2 , Figure 3 The outer surface of cylinder 64 is slidably connected to slider 65. The top surface of slider 65 is eccentrically connected to two fixed cylinders 66, which are symmetrically arranged. The inner wall of fixed cylinder 66 is fixedly connected to movable column 67. The side of movable column 67 away from fixed cylinder 66 is fixedly connected to the top surface of the inner wall of auxiliary frame 62. Two return springs 68 are fixedly connected to the eccentric top surface of slider 65. The side of return spring 68 away from slider 65 is fixedly connected to the top surface of the inner wall of auxiliary frame 62. Return spring 68 is sleeved on the outer surface of fixed cylinder 66 and movable column 67. The bottom surface of slider 65 is eccentrically connected to two fixed cylinders 69, which are symmetrically arranged. The inner wall of the fixed cylinder 69 is slidably connected to the movable column 610. Two return springs 611 are fixedly connected to the eccentric part of the bottom surface of the slider 65. The side of the return spring 611 away from the slider 65 is fixedly connected to the bottom surface of the inner wall of the auxiliary frame 62. The return spring 611 is sleeved on the outer surface of the fixed cylinder 69 and the movable column 610. The outer surface of the movable column 67 and the movable column 610 can be fixed with a limiting ring. The outer surface of the fixed cylinder 66 and the fixed cylinder 69 can be provided with a limiting groove. When the movable column 67 and the movable column 610 slide to the maximum limit, the limiting ring can be engaged in the limiting groove to prevent the movable column 67 and the movable column 610 from separating from the fixed cylinder 66 and the fixed cylinder 69.

[0043] In use, when the slider 65 moves upward, the first moving column 67 slides inside the first fixed cylinder 66 and presses the first return spring 68. Conversely, when the slider 65 moves downward, the second moving column 610 slides inside the second fixed cylinder 69 and presses the second return spring 611. This design ensures that the roller 7 always maintains a stable pressure against the bottom of the grinding wheel body 5. No matter what minor unevenness or vibration exists on the surface of the grinding wheel body 5 during rotation, the first return spring 68 and the second return spring 611 can adjust the position and pressure of the roller 7 in time to ensure that the roller 7 always has good contact with the bottom of the grinding wheel body 5, thereby obtaining more accurate thickness measurement data.

[0044] Reference Figure 4 , Figure 5 One side of the slider 65 is fixedly connected to the connecting plate 612. The connecting plate 612 is slidably connected inside the auxiliary frame 62. One side of the connecting plate 612 is fixedly connected to the fixed plate 613. The inner wall of the fixed plate 613 is slidably connected to the movable plate 615. One side of the movable plate 615 is rotatably connected to the roller 7, and the roller 7 is located away from the fixed plate 613. The inner wall of the fixed plate 613 is inserted into the movable plate 615. The inner wall of the movable plate 615 has a first insertion hole 616 and a second insertion hole 6161, and the first insertion hole 616 and the second insertion hole 6161 are adapted to be inserted into the fixed plate 613. When the insertion post 614 is inserted into the first insertion hole 616... When the roller 7 is far away from the grinding wheel body 5, it indicates that the roller 7 is not affecting the use of the grinding wheel body 5. When the insertion post 614 is inserted into the second insertion hole 6161, it indicates that the roller 7 is inside the grinding wheel body 5. At this time, the thickness of the grinding wheel body 5 can be detected. The outer surface of the slider 65 is fixedly connected to the pointer 617, and the pointer 617 is designed at a right angle to the first connecting plate 612. The outer surface of the auxiliary frame 62 is printed with several scale lines 618 for real-time indication of the thickness of the grinding wheel body 5. The outer surface of the slider 65 is engaged with the marker pen 620, which is located above the pointer 617. The outer surface of the auxiliary frame 62 is fixedly connected to the indicator plate 619.

[0045] As the roller 7 moves up and down following the thickness of the grinding wheel body 5, it drives the slider 65 to move up and down as well, so that the pointer 617 can point to the scale line 618 in real time. At the same time, the marker pen 620 draws a line on the outer surface of the indicator plate 619. This intuitive presentation method not only makes it convenient for operators to quickly read the value of the grinding wheel thickness, but also allows them to intuitively judge the uniformity of the grinding wheel thickness and whether there are abnormalities such as local wear by observing the shape and changes of the drawn lines. This provides more comprehensive and accurate information for the quality assessment and maintenance of the grinding wheel.

[0046] The motor is a DC geared motor, and the motor wiring is located inside the auxiliary frame 62. In this device, the return spring 68 and the return spring 611 both use the calculation formula for alloy springs: F = kx, where F is the external force on the spring, k is the spring constant, and x is the deformation of the spring. The elastic force of the alloy spring is then calculated to enable its use in this device. The materials of the return spring 68 and the return spring 611 are high-strength alloy steel to ensure the durability and stability of the return spring 68 and the return spring 611 in long-term use.

[0047] The implementation principle of the automatic grinding wheel thickness detection device in this application embodiment is as follows:

[0048] In use, the grinding wheel body 5 is driven to rotate by the drive device 3, thereby grinding the object to be ground. During grinding, water is sprayed onto the grinding wheel body 5 through the water spray pipe 2 to reduce the temperature of the grinding wheel body 5. In addition, the roller 7 can be attached to the bottom edge of the grinding wheel body 5. One of the rollers is driven to rotate by the motor. The rotation of the roller drives the connecting plate to move in the groove of the track 61, thereby allowing the roller 7 to move on the bottom surface of the grinding wheel body 5 for multi-point detection.

[0049] When slider 65 moves up or down, it causes moving column 610 to slide inside fixed cylinder 69, compressing return spring 68 and return spring 611. Regardless of any minor unevenness or vibration on the surface of the grinding wheel body 5 during rotation, return spring 68 and return spring 611 can promptly adjust the position and pressure of roller 7, ensuring that roller 7 always maintains good contact with the bottom of the grinding wheel body 5. When slider 65 moves up and down, pointer 617 can point to scale line 618 in real time, while marker pen 620 draws lines on the outer surface of indicator plate 619. This intuitive presentation not only makes it convenient for operators to quickly read the grinding wheel thickness value, but also allows them to intuitively judge the uniformity of grinding wheel thickness and the presence of abnormalities such as local wear by observing the shape and changes of the drawn lines, providing more comprehensive and accurate information for grinding wheel quality assessment and maintenance.

[0050] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
