Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machine tool processing equipment, more particularly to a centerless grinding machine based on laser online measurement and automatic compensation function. BACKGROUND

[0002] Grinding is a kind of precision cutting process using high-speed rotating grinding wheel and other grinding tools on the workpiece surface, which is widely used in the field of finishing in mechanical manufacturing. Grinding is the final process in many cases, so the grinding precision has a direct impact on the final precision of the workpiece. Traditional grinding is produced by manually adjusting the feed amount of the grinding wheel, which results in poor consistency and unstable quality, and is prone to produce waste products.

[0003] Most of the centerless grinding machines currently use manual feeding, mainly through rotating hand wheels or screw mechanisms to achieve rough adjustment close to the workpiece diameter, and then fine adjustment to ensure smooth rolling of the workpiece and the centering of the contact point. At the same time, the guide plate needs to be adjusted synchronously to ensure that it is parallel to the workpiece surface without gaps. After grinding, manual measurement of the outer diameter is required using a micrometer or a lever micrometer, and the measurement needs to be stopped. In the case of single-piece or small-batch production, repeated stoppage for measurement and subsequent adjustment are required, which not only reduces efficiency but also relies heavily on the operator's experience. In batch production, errors are likely to occur, thereby reducing the quality of the ground workpiece. Therefore, the prior art proposes a linkage robot that realizes online monitoring of the outer diameter through a grating sensor combined with a single-chip microcomputer and compensates for processing errors through PID control. However, the comprehensive cost of the numerical control centerless grinding machine + robot + grating sensor measurement system can be several times that of traditional equipment. In addition, failure of the grating sensor measurement unit can cause the entire line to stop, making subsequent processing impossible. Furthermore, vibration during grinding can cause dust or cutting fluid to splash, which can interfere with the accuracy of the grating measurement, thereby greatly reducing the accuracy and efficiency of the workpiece.

[0004] In view of the above, the present application designs a centerless grinding machine based on laser online measurement and automatic compensation function to solve the above technical problems. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application aims to provide a centerless grinding machine based on laser online measurement and automatic compensation function, which solves the problem of low efficiency of workpiece grinding due to the need for repeated stoppage for measurement and adjustment of workpiece diameter when the centerless grinding machine grinds workpieces.

[0039] The working principle and working process, before the workpiece grinding starts, the operator first stores the workpiece needing to be ground on the workpiece placing plate 12, and then clamps the workpiece through the moving rod 22 and the two side clamping handles 24. Since the moving rod 22 and the clamping handle 24 are provided with a first roller 221 and a second roller 241 at one end, when the moving rod 22 and the clamping handle 24 adaptively clamp the workpiece, the first roller 221 and the second roller 241 can fit the outer diameter of the workpiece. When the workpiece is clamped, the workpiece needs to be moved downward with the surface of the moving rod 22. At this time, the moving rod 22 extrudes the return spring 23 downward. At this time, the second roller 241 provided at the other end of the clamping handle 24 slides on the surface of the trapezoidal structure below the moving rod 22, so that the two clamping handles 24 rotate towards the middle. At this time, the two clamping handles 24 can fit the circumferential surface of the workpiece, so as to clamp and fix the workpiece, so as to clamp workpieces of different diameters. At the same time, the longer workpiece can fix one end of the workpiece, so as to avoid the vibration phenomenon of the long workpiece during grinding;

[0040] When the moving rod 22 and the clamping handle 24 adaptively clamp the workpiece, the moving rod 22 can drive the driving block 222 to move synchronously. The driving block 222 moves in contact with the inclined surface 331 of the contact block 33. When the moving rod 22 moves downward, the inverted trapezoidal driving block 222 moves downward synchronously. The driving block 222 pushes the contact block 33 to extrude the connecting spring 34, so that the two side rectangular protective covers 3 extrude the control spring 4 to the two 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. The driving block 222 no longer pushes the contact block 33, and the connecting spring 34 resets, so that the control spring 4 pushes the rectangular protective cover 3 to move to 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 is arranged on the driving block 222, so that sliding friction is changed into rolling friction, thereby avoiding the interference phenomenon of the driving block 222 pushing the contact block 33, and ensuring the stability of movement;

[0041] After the workpiece is ground, the workpiece is moved on the workpiece supporting plate 151 through the rotation of the guide wheel 6, the outer diameter of the workpiece is detected through the laser detector 131, if the outer diameter of the workpiece is greater than the standard value, at this time, the driving motor 71 arranged on one side of the grinding wheel 5 and the guide wheel 6 is started, the driving motor 71 drives the driving gear 72 to rotate, the first driven wheel 73 and the second driven wheel 74 are driven to rotate through the driving gear 72, when the two driving motors 71 rotate forward, at this time, the driving gear 72 drives the first driven wheel 73 and the second driven wheel 74 to rotate, so that the grinding wheel 5 and the guide wheel 6 move to the middle, thereby reducing the distance between the grinding wheel 5 and the guide wheel 6, if the outer diameter of the workpiece is less than the standard value, at this time, the driving motor 71 arranged on one side of the grinding wheel 5 and the guide wheel 6 is started, the driving motor 71 drives the driving gear 72 to rotate, the first driven wheel 73 and the second driven wheel 74 are driven to rotate through the driving gear 72, when the two driving motors 71 rotate reversely, at this time, the driving gear 72 drives the first driven wheel 73 and the second driven wheel 74 to rotate, so that the grinding wheel 5 and the guide wheel 6 move to the two 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 driving motor 71 stops, so that the subsequent workpiece processed all meets the standard value, after processing is completed, the workpiece is conveyed through the output roller 142, so that the processed workpiece falls on the workpiece placing plate 12 on the other side of the base 1.

[0042] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application, the protection scope of the present application is defined by the claims, those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, the modification or equivalent replacement is also regarded as falling within the protection scope of the present application.
