Description

Grinding wheel wear compensation device and method Technical Field

[0001] This application relates to the fields of grinding machine processing and automated testing technology, and in particular to grinding wheel wear compensation devices. Background Technology

[0002] In the field of grinding, the grinding wheel, as the main cutting tool, gradually reduces its working diameter due to continuous wear, leading to loss of dimensional accuracy in the machined workpiece. Therefore, real-time and accurate detection and compensation of grinding wheel wear is a crucial step in ensuring machining quality.

[0003] Currently, common methods for compensating for grinding wheel wear in the industry mainly employ mechanical measuring tools such as dial indicators and probes. After the grinding wheel stops rotating, its outer diameter or thickness is directly measured. The measured value is then compared with the initial value to determine the amount of wear.

[0004] The main drawback of this method is that the processing flow must be interrupted for measurement, which severely impacts production efficiency. Furthermore, for equipment such as large vertical grinders, the grinding wheel is mounted high up, making manual contact measurement not only inconvenient but also posing certain safety risks.

[0005] At the same time, after a period of use, the grinding wheel may still have a certain amount of adhering powder on its surface. This powder layer can also interfere with the detection of the wear of the grinding wheel, leading to detection errors.

[0006] In other words, existing technologies have the following technical problems: conventional detection methods require manual contact measurement, which is inefficient and easily affected by the powder layer on the grinding wheel surface. Therefore, a grinding wheel wear compensation device is proposed to address these issues. Summary of the Invention

Detailed Implementation

[0057] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0058] Please refer to Figures 1 and 2 for the grinding wheel wear compensation device, which includes the grinding wheel body 1;

[0059] It also includes a photoelectric sensing component 2, which is located on the side of the grinding wheel body 1 and is movable relative to the grinding wheel body 1;

[0060] The photoelectric sensing component 2 includes a transmitter 201 and a receiver 202, which are respectively located on both sides of the grinding wheel body 1. During relative movement, the receiver 202 generates an on / off signal to accurately detect the position of the edge of the grinding wheel body 1, indicating whether the light beam emitted by the transmitter 201 is blocked by the edge of the grinding wheel body 1.

[0061] This application uses a mechanically driven photoelectric sensor component 2 to actively approach the grinding wheel for positioning detection, and utilizes the automatic driving cleaning and blowing function during the detection motion process to realize the detection of the edge position of the grinding wheel under harsh working conditions, thereby accurately calculating the wear of the grinding wheel and realizing the compensation function for the machining coordinates of the machine tool.

[0062] In a preferred embodiment of this application, referring to Figures 3 and 4, the photoelectric sensing component 2 is fixedly mounted on the moving detection component 3. The moving detection component 3 is used to carry and drive the photoelectric sensing component 2 to perform linear reciprocating motion in a direction parallel to the radial direction of the grinding wheel, so as to achieve relative displacement between it and the grinding wheel body 1.

[0063] The moving detection component 3 includes a transverse guide rod 303, a linear moving seat 305, and a drive unit. There are two linear moving seats 305, which are mirror images of each other on both sides of the grinding wheel body 1.

[0064] Specifically, the transmitting end 201 is fixedly installed on the side wall of one of the linear moving seats 305, and the receiving end 202 is fixedly installed on the side wall of the other linear moving seat 305. By driving the two linear moving seats 305 to move towards or away from each other simultaneously by the driving unit, it can be ensured that the transmitting end 201 and the receiving end 202 always remain aligned and move towards or away from the grinding wheel body 1 in sync, thereby ensuring the accurate alignment of the detection beam and the consistency of the detection reference.

[0065] Further, referring to Figure 4, the transverse guide rod 303 passes through the linear motion seat 305 and slides with the linear motion seat 305 to form a high-precision linear guide pair, which is used to constrain the movement trajectory of the linear motion seat 305 to ensure that its movement is smooth and its direction is strictly parallel to the feed direction of the grinding wheel. One end of the transverse guide rod 303 is fixedly connected to the first mounting plate 302, and the other end of the transverse guide rod 303 is fixedly connected to the second mounting plate 304. A fixed bracket 301 is also fixedly connected to one end of the first mounting plate 302 to rigidly install the entire moving detection assembly 3 at a suitable position on the grinding machine body.

[0066] Furthermore, referring to Figure 4, the drive unit of the motion detection component 3 includes a drive screw 306 and a servo motor 312.

[0067] The drive screw 306 is disposed between the first mounting plate 302 and the second mounting plate 304 and is rotatably connected to the first mounting plate 302 and the second mounting plate 304. The drive screw 306 passes through the linear motion seat 305 and is threadedly engaged with the linear motion seat 305, and is used to accurately convert the rotational motion of the drive screw 306 into the linear motion of the linear motion seat 305.

[0068] A servo motor 312 is fixedly mounted on one side of the second mounting plate 304. The output shaft end of the servo motor 312 is fixedly connected to one end of the drive screw 306. Through this technical solution, when the servo motor 312 receives the command from the control system, it can accurately control the rotation angle and direction of the drive screw 306, thereby realizing precise control of the moving distance and speed of the photoelectric sensing component 2, and thus providing a guarantee for high repeatability position detection.

[0069] As a preferred technical solution, in order to enable the drive screws 306 on both sides to rotate in strict synchronization, thereby ensuring that the displacement of the linear moving seats 305 on both sides is completely synchronized, as shown in Figure 2, a first bevel gear 307 is also fixedly connected to one end of the drive screw 306.

[0070] A connecting horizontal plate 308 is fixedly connected between the two first mounting plates 302. A support bracket 309 is fixedly connected to the side wall of the connecting horizontal plate 308. A linkage rod 310 is rotatably connected to the support bracket 309. A second bevel gear 311 is fixedly connected to both ends of the linkage rod 310. The second bevel gear 311 meshes with the first bevel gear 307.

[0071] With this technical solution, when one of the drive screws 306 is driven by the servo motor 312, the power can be transmitted to the linkage rod 310 through the meshing of the first bevel gear 307 and the second bevel gear 311. Then, the bevel gear pair at the other end of the linkage rod 310 drives the drive screw 306 on the other side, thereby ensuring that the drive mechanisms on both sides achieve forced mechanical synchronization.

[0072] In one specific embodiment of this application, as shown in Figures 4 and 5, a spray cleaner 4 is fixedly connected to the side wall of the linear moving seat 305.

[0073] The spray cleaner 4 includes a fixed housing 401, a jet nozzle 402, and a spray nozzle 403.

[0074] A jet nozzle 402 is fixedly installed at the front end of the fixed housing 401. A central inner cavity 404 is provided inside the fixed housing 401. The central inner cavity 404 and the jet nozzle 402 are connected through an internal flow channel to guide high-pressure gas to be ejected from the jet nozzle 402.

[0075] The front end of the fixed housing 401 is also fixedly connected to a spray nozzle 403. The interior of the fixed housing 401 is provided with an annular cavity 405. The annular cavity 405 and the spray nozzle 403 are connected through an internal flow channel to guide the atomized cutting fluid or cleaning fluid to the spray nozzle 403 for spraying.

[0076] With this technical solution, when the photoelectric sensing component 2 moves toward the grinding wheel to prepare for detection or resets after detection, the jet nozzle 402 can be activated to spray out a high-speed airflow to blow away the loose dust attached to the side of the grinding wheel.

[0077] In a preferred embodiment of this application, as shown in Figures 6 and 7, a linkage liquid supply mechanism 5 is also fixedly connected to the mobile detection component 3.

[0078] The linkage liquid supply mechanism 5 includes a liquid supply cylinder 504, a linkage gear 508 and a rack 507. An auxiliary fixing plate 501 is fixedly connected to the side wall of the connecting horizontal plate 308. A guide groove is provided on the auxiliary fixing plate 501, and a guide slider 502 is slidably connected in the guide groove of the auxiliary fixing plate 501.

[0079] The bottom end of the auxiliary fixing plate 501 is fixedly connected to a first mounting bracket 503. The upper surface of the first mounting bracket 503 is fixedly connected to a liquid supply cylinder 504. The inner cavity of the liquid supply cylinder 504 is slidably connected to a first moving piston 505. The upper end of the first moving piston 505 is fixedly connected to one end of a moving guide rod 506. The other end of the moving guide rod 506 passes through the upper wall of the inner cavity of the liquid supply cylinder 504 and extends to the outside of the wall. The top end of the moving guide rod 506 is fixedly connected to a guide slider 502.

[0080] A rack 507 is fixedly connected to the upper surface of the guide slider 502, and a linkage gear 508 is fixedly installed on the arc-shaped wall of the linkage rod 310. The rack 507 and the linkage gear 508 mesh with each other, thereby converting the rotational motion of the linkage rod 310 into the linear reciprocating motion of the rack 507, which in turn drives the first moving piston 505 to reciprocate within the liquid supply cylinder 504 via the moving guide rod 506.

[0081] As a further technical solution, referring to Figure 8, an output hose 509 is fixedly connected to the bottom side of the inner cavity of the liquid supply cylinder 504. The output hose 509 is connected to the annular inner cavity 405 of the spray cleaner 4 and is used to deliver liquid to the spray nozzle 403. An input hose 510 is fixedly connected to the bottom side of the inner cavity of the liquid supply cylinder 504. One end of the input hose 510 is used to connect to an external cutting fluid or cleaning fluid source.

[0082] Furthermore, an output check valve 5091 is fixedly installed on the output hose 509, and its flow direction is limited to allow liquid to flow only from the supply cylinder 504 to the annular cavity 405. An input check valve 5101 is fixedly installed on the input hose 510, and its flow direction is limited to allow liquid to flow only from an external liquid source into the supply cylinder 504. Specifically, these two check valves, together with the reciprocating motion of the first moving piston 505, constitute a piston pump structure.

[0083] With the above technical solution, when the moving detection component 3 drives the photoelectric sensing component 2 to move towards the grinding wheel for detection, the linkage rod 310 rotates and drives the linkage gear 508 to rotate, driving the rack 507 and the guide slider 502 to move in one direction, driving the first moving piston 505 to press down. At this time, the output one-way valve 5091 opens, pressing the liquid in the cylinder into the output hose 509, and finally spraying it out from the spray nozzle 403.

[0084] When the moving detection component 3 drives the photoelectric sensing component 2 to reset, the linkage rod 310 rotates in the opposite direction, thereby pulling the first moving piston 505 upward. At this time, the input one-way valve 5101 opens, drawing external liquid into the lower chamber of the supply cylinder 504. This process converts the mechanical energy of the detection motion itself into the power for the delivery of cleaning fluid, eliminating the need for an additional electric pump and thus saving energy.

[0085] In a preferred embodiment of this application, referring to FIG9, an auxiliary jetting mechanism 6 is also fixedly connected to the side of the linkage liquid supply mechanism 5.

[0086] The auxiliary jetting mechanism 6 includes a gas cylinder 607, a contact part 610, a transmission rod 602, and a rotating disk 604. A U-shaped mounting bracket 601 is fixedly connected to the side wall of the auxiliary fixing plate 501, a second mounting leg 606 is fixedly connected to the side wall of the U-shaped mounting bracket 601, and a gas cylinder 607 is fixedly connected to the upper surface of the second mounting leg 606.

[0087] A second movable piston 608 is slidably connected within the inner cavity of the gas cylinder 607. One end of a reciprocating guide rod 609 is fixedly connected to the upper surface of the second movable piston 608. The other end of the reciprocating guide rod 609 penetrates the upper wall of the inner cavity of the gas cylinder 607 and extends outside the wall. A contact portion 610 is fixedly connected to the upper end of the reciprocating guide rod 609. A return spring 611 is fixedly connected between the bottom surface of the contact portion 610 and the upper surface of the gas cylinder 607, which provides downward pressure to reset the contact portion 610 after it loses external pushing force.

[0088] Furthermore, the transmission rod 602 is rotatably connected to the U-shaped mounting bracket 601 via a bearing. A transmission gear 603 is fixedly connected to one end of the transmission rod 602, and the transmission gear 603 meshes with the linkage gear 508 of the linkage liquid supply mechanism 5. Thus, when the linkage gear 508 rotates with the detection stroke, it can drive the transmission gear 603 to rotate synchronously with the transmission rod 602. A rotating disk 604 is fixedly connected to the other end of the transmission rod 602, and at least one protrusion 605 is fixedly provided on the outer circumference of the rotating disk 604.

[0089] The core working principle of the auxiliary jet mechanism 6 is that when the moving detection component 3 drives the photoelectric sensing component 2 to move toward the grinding wheel to perform detection, the rotating disk 604 is driven to rotate through gear meshing.

[0090] When the protrusion 605 on the rotating disk 604 rotates to contact the contact part 610, it continues to rotate, pushing the contact part 610 together with the reciprocating guide rod 609 and the second moving piston 608 upward. This process stretches the return spring 611 and increases the volume of the lower chamber of the gas cylinder 607, forming a negative pressure to draw in gas.

[0091] Subsequently, after the protrusion 605 rotates past its highest point, the pushing force on the contact part 610 disappears. At this time, the stretched return spring 611 releases its elastic potential energy, driving the contact part 610, the reciprocating guide rod 609 and the second moving piston 608 to move rapidly downward, compressing and expelling the gas in the lower chamber of the gas cylinder 607.

[0092] When the rotating disk 604 rotates continuously, the protrusion 605 periodically pushes up the contact part 610 and periodically presses down under the action of the return spring 611, thereby realizing a continuous and reciprocating pumping function.

[0093] As a preferred technical solution, in order to enable efficient coordination between the pumping action and the detection process, a one-way clutch is provided between the transmission gear 603 and the transmission rod 602.

[0094] The one-way clutch is configured such that power is transmitted to the transmission rod 602 to drive the rotating disk 604 only when the transmission gear 603 rotates in the direction of the corresponding photoelectric sensing component 2 to perform the detection stroke; when the transmission gear 603 rotates in the opposite direction, that is, when the corresponding photoelectric sensing component is in the reset stroke, the one-way clutch slips, and the transmission rod 602 and the rotating disk 604 remain stationary.

[0095] This design ensures that the auxiliary jet mechanism 6 only operates during the detection stroke, providing air supply for pre-detection purging, and does not operate during the reset stroke, thus improving system energy efficiency and mechanism lifespan.

[0096] Furthermore, referring to Figure 10, the lower chamber of the gas cylinder 607 is connected to a gas input pipe 613 and a gas output pipe 612.

[0097] The gas inlet pipe 613 is connected to an external clean gas source or air filter, and a second one-way valve 6131 is installed on it, which only allows external gas to flow into the lower chamber of the gas cylinder 607.

[0098] The gas output pipe 612 is connected to the central inner cavity 404 of the spray cleaner 4, and a first one-way valve 6121 is installed on it. This valve only allows gas to flow from the lower cavity of the gas cylinder 607 to the jet nozzle 402.

[0099] With this technical solution, when the second moving piston 608 moves upward to draw in air, the second one-way valve 6131 opens to replenish the gas; when it moves downward to exhaust air, the first one-way valve 6121 opens, spraying a pulsed airflow through the jet nozzle 402 onto the grinding wheel detection surface, completing the automatic purging. The entire pumping process is mechanically driven by the detection movement itself, eliminating the need for an external electric air pump and thus saving energy.

[0100] A method for compensating for grinding wheel wear includes the following steps:

[0101] A. Control the moving detection component 3 to drive the photoelectric sensing component 2 to move toward the grinding wheel body 1 to perform the detection stroke;

[0102] B. During the detection process, when the receiving end 202 of the photoelectric sensing component 2 is first triggered by the edge of the grinding wheel body 1 to change the signal, the first trigger position is recorded.

[0103] C. Control the movement detection component 3 to drive the photoelectric sensing component 2 to move in the opposite direction to perform the return stroke; during the return stroke, when the receiver 202 triggers a signal change again due to the edge of the grinding wheel body 1, record the second trigger position;

[0104] D. Calculate the reference position of the grinding wheel edge based on the first trigger position and the second trigger position; calculate the wear amount of the grinding wheel body 1 based on the reference position and the preset initial zero position.

[0105] The current reference position (P reference) of the grinding wheel edge is calculated using the formula: P reference = (P1 + P2) / 2; where P1 is the first trigger position recorded in step B, and P2 is the second trigger position recorded in step C. This step aims to eliminate the backlash error of the movement detection component 3 itself.

[0106] Based on the difference between the current reference position (P reference) and the initial zero position, the total wear of the grinding wheel in the radial direction since calibration is calculated.

[0107] Based on the total wear amount, a corresponding compensation command is generated and sent to the machine tool CNC system to drive the grinding wheel feed axis to perform corresponding position compensation in order to maintain constant machining dimensions.

[0108] The circuits, electronic components, and modules involved are all existing technologies, and can be fully implemented by those skilled in the art.

[0109] The above description is merely a preferred embodiment of this application and is 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.
