Description

Technical Field

[0001] The present invention relates to the technical field of machine tool processing equipment, and more particularly to a centerless grinder based on laser online measurement and automatic compensation functions. Background Art

[0002] Grinding is a process that uses high-speed rotating grinding wheels and other abrasive tools to precisely cut the surface of workpieces. It is widely used in the field of finishing in mechanical manufacturing. In many cases, grinding is the last step in workpiece processing. Therefore, the grinding accuracy has a direct impact on the final accuracy of the processed workpiece. Traditional grinding relies on experience and manual operation of the grinding wheel feed rate. The products produced in this way have poor consistency, unstable quality, and are prone to waste.

[0003] Currently, most centerless grinders use manual feed, primarily by rotating a handwheel or screw mechanism. Coarse adjustment is first performed to approximate the workpiece diameter, followed by fine adjustment until the workpiece can roll smoothly and the contact point is centered. The guide plate also needs to be adjusted synchronously to ensure it is parallel to the workpiece surface without gaps. After grinding, the outer diameter must be manually measured using a micrometer or lever micrometer, and the machine must be stopped for measurement. For small-batch production of single pieces, repeated stoppages for measurement and subsequent adjustments are necessary. This is not only inefficient but also relies heavily on operator experience, making errors more likely to occur in batch production, thereby reducing the quality of the ground workpiece. To address this issue, existing technologies have proposed a linked robot that uses a grating sensor combined with a single-chip microcomputer to achieve online outer diameter monitoring and compensate for machining errors through PID control. However, the combined cost of a CNC centerless grinder, robot, and grating sensor measurement system can be several times that of traditional equipment. Failure of the grating sensor measurement unit can cause the entire line to shut down, preventing subsequent processing. Furthermore, vibrations in the workpiece during grinding can cause dust or cutting fluid splashes, which can interfere with the grating measurement accuracy, significantly reducing workpiece accuracy and efficiency.

[0004] In view of the above situation, the present invention designs a centerless grinder based on laser online measurement and automatic compensation functions to solve the above technical problems. Summary of the Invention

[0027] Specifically, the rectangular protective cover 3 is provided with a movable groove 31 on the side close to the driving component 2, and the rectangular protective cover 3 is provided with a rectangular groove 32 on the side away from the driving component 2. The grinding wheel 5 and the guide wheel 6 are respectively arranged in the rectangular protective cover 3 on both sides, and one end of the grinding wheel 5 and the guide wheel 6 is slidably arranged in the movable groove 31, and the other end of the grinding wheel 5 and the guide wheel 6 is arranged in the rectangular groove 32 through the adjustment component 7.

[0028] Specifically, the adjustment assembly 7 includes a drive motor 71, a drive gear 72, a number one driven wheel 73, a number two driven wheel 74 and a support plate 75.

[0030] Working principle and working process: before the workpiece grinding begins, the operator first places the workpiece to be ground on the workpiece placement plate 12, and then clamps the workpiece through the moving rod 22 and the clamping handles 24 on both sides. Since the moving rod 22 and one end of the clamping handle 24 are provided with a No. 1 roller 221 and a No. 2 roller 241, when the moving rod 22 and the clamping handle 24 perform adaptive clamping on the workpiece, the No. 1 roller 221 and the No. 2 roller 241 can fit the outer diameter of the workpiece. When the workpiece is clamped, the workpiece needs to be close to the workpiece. The surface of the movable rod 22 moves downward, and the movable rod 22 presses the return spring 23 downward. At this time, the second roller 241 provided at the other end of the clamping handle 24 slides against the trapezoidal structure surface below the movable rod 22, so that the clamping handles 24 on both sides rotate toward the middle. At this time, the clamping handles 24 on both sides can fit the circumferential surface of the workpiece, thereby clamping and fixing the workpiece, so that workpieces of different diameters can be clamped. At the same time, a longer workpiece can be fixed at one end of the workpiece to avoid vibration of the long workpiece during grinding; When the moving rod 22 and the clamping handle 24 adaptively clamp the workpiece, the movement of the moving rod 22 can drive the driving block 222 to move synchronously, and the driving block 222 moves in contact with the inclined surface 331 provided on the contact block 33. When the moving rod 22 moves downward, the inverted trapezoidal driving block 222 moves downward synchronously, and the driving block 222 pushes the contact block 33 to squeeze the connecting spring 34, so that the rectangular protective covers 3 on both sides squeeze the control spring 4 to both sides, thereby increasing the distance between the grinding wheel 5 and the guide wheel 6. When the moving rod 22 moves upward, the inverted trapezoidal driving block 222 moves upward synchronously, and the driving block 222 no longer pushes the contact block 33, and the connecting spring 34 is reset, so that the control spring 4 pushes the rectangular protective cover 3 to move toward the middle, thereby reducing the distance between the grinding wheel 5 and the guide wheel 6, so that the workpiece can be ground according to the preset size. In order to ensure that the driving block 222 can better push the contact block 33, the contact roller provided on the driving block 222 is used to convert the sliding friction into rolling friction, thereby avoiding interference between the driving block 222 and the contact block 33, thereby ensuring the smoothness of the movement; After the workpiece is ground, the workpiece is driven to move on the workpiece support plate 151 by the rotation of the guide wheel 6, and the outer diameter of the workpiece is detected by the laser detector 131. If the outer diameter of the workpiece is larger than the standard value, the drive motor 71 set on one side of the grinding wheel 5 and the guide wheel 6 is started, and the drive motor 71 drives the drive gear 72 to rotate, and drives the No. 1 driven wheel 73 and the No. 2 driven wheel 74 to rotate through the drive gear 72. When the drive motors 71 on both sides rotate forward, the drive gear 72 drives the No. 1 driven wheel 73 and the No. 2 driven wheel 74 to rotate, so that the grinding wheel 5 and the guide wheel 6 move toward the middle, thereby reducing the distance between the grinding wheel 5 and the guide wheel 6. If the outer diameter of the workpiece is smaller than the standard value, the grinding wheel 5 and The drive motor 71 provided on one side of the guide wheel 6 is started, and the drive motor 71 drives the drive gear 72 to rotate, and drives the No. 1 driven wheel 73 and the No. 2 driven wheel 74 to rotate through the drive gear 72. When the drive motors 71 on both sides are reversed, the drive gear 72 drives the No. 1 driven wheel 73 and the No. 2 driven wheel 74 to rotate, so that the grinding wheel 5 and the guide wheel 6 move to both sides, thereby reducing the distance between the grinding wheel 5 and the guide wheel 6. When the outer diameter of the workpiece meets the standard value, the drive motor 71 stops, so that the subsequent workpieces meet the standard value after processing. After the processing is completed, the workpiece is transported by the output roller 142, so that the processed workpiece falls onto the workpiece placement plate 12 on the other side of the base 1.

[0031] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
