[0002] As a special equipment using CNC technology, CNC roll grinders are mainly used for grinding and repairing rolls. They have the characteristics of high precision, high efficiency and high degree of automation, and are widely used in industries such as steel and rolling mill manufacturing. In order to monitor the wear and tear of the grinding wheel in real time, replace the grinding wheel in time, and ensure the grinding and repair accuracy, CNC roll grinders are often equipped with a mechanism to measure and monitor the diameter or radius of the grinding wheel.

[0003] In existing ruler-type monitoring mechanisms, the measuring scale lines are mostly directly engraved on the main body of the ruler component. As a result, the scale lines are blurred by splashing iron filings in a high-temperature molten state during processing or are eroded by high temperature. When they need to be replaced, the ruler component must be replaced as a whole, and the scale line component cannot be disassembled and replaced separately, resulting in high maintenance costs for the monitoring mechanism for damaged scale lines.

[0008] Furthermore, an L-shaped mounting plate is welded to the right side of the head end of the rod sleeve, and the right side vertical support portion of the U-shaped inserting frame is slidably fitted with the horizontal portion of the L-shaped mounting plate.

The U-shaped scale plate 505 is installed by sliding. When the scale line is blurred by the splashing of high-temperature molten iron filings during the processing or needs to be replaced after high-temperature erosion, the U-shaped scale plate 505 can be slid forward and pulled out from the rod sleeve 5 for separate disassembly and replacement. Compared with the existing technology of directly engraving the measuring scale lines on the main body of the ruler component, there is no need to replace the entire ruler component, which helps to reduce the maintenance cost of the monitoring mechanism for damage to the scale lines.

[0040] A track shaft 507 is welded to the inside of the rod sleeve 5, and the measuring rod 501 is slidably fitted with the track shaft 507 through a spring push, and a positioning piece 6 is slidably installed on the tail end part of the track shaft 507. The tail end of the spring on the measuring rod 501 is in contact with the positioning piece 6. The spring on the track shaft 507 can simultaneously push the measuring rod 501 and the positioning piece 6, which has the effect of using one device for two purposes. This saves the need to respectively configure elastic pushing components for the measuring rod 501 and the positioning piece 6, helps to simplify the structure of the measuring component composed of the measuring rod 501 and the rod sleeve 5, and is beneficial to the integration and miniaturization of the measuring component.

[0041] Preferably, the measuring rod 501 is in an L-shaped structure, and a guide wheel is rotatably mounted on the bent portion of the head end of the measuring rod 501;

[0042] A T-shaped slide block 5011 is welded to the tail end of the measuring rod 501 , and a long slide groove 502 is provided between two T-shaped slide grooves on the left side wall of the rod sleeve 5 , and the T-shaped slide block 5011 is slidably matched with the long slide groove 502 .

[0043] Preferably, an L-shaped mounting plate 503 is welded to the right side of the head end of the rod sleeve 5 , and the right side vertical support portion of the U-shaped insert frame 504 is slidably fitted with the horizontal portion of the L-shaped mounting plate 503 .

[0044] Preferably, the positioning member 6 is composed of an L-shaped plug rod 601, an L-shaped push plate welded to the top end of the L-shaped plug rod 601, and a shaft ring welded to the tail end of the L-shaped plug rod 601, wherein the shaft ring is slidably matched with the track shaft 507;

[0045] A short slide groove 506 is formed through the tail end of the right side wall of the rod sleeve 5 , and the long rod portion of the L-shaped insertion rod 601 is slidably matched with the short slide groove 506 .

[0046] Preferably, a protruding mounting plate is welded to the middle position of the rear side of the grinder base 1, and a vertical support 3 is installed on the top of the protruding mounting plate in a straight sliding manner forward and backward. A protective cover 302 is welded to the top of the vertical support 3, and a grinding wheel 301 is rotatably installed inside the protective cover 302.

[0047] Preferably, a mounting post 304 is welded at the middle rear end of the left side wall of the protective cover 302, and the tail end of the rod sleeve 5 is rotatably matched with the mounting post 304. The rod sleeve 5 and the mounting post 304 are rotatably mounted. When the grinding wheel 301 or the roller 2 is disassembled and replaced in an idle state, it can be swung downward to vacate the loading and unloading operation space on the front side and the left and right sides, so as to avoid obstruction to the disassembly and transfer of the grinding wheel 301 or the roller 2, and avoid causing its body to be bent or broken by collision;

[0048] The short rod part of the L-shaped plug rod 601 is inserted and matched with the installation column 304. Through the L-shaped plug rod 601, the positioning member 6 can insert and position the rod sleeve 5 in a horizontal measurement use state. Pushing the L-shaped push plate forward can drive the L-shaped plug rod 601 to separate from the installation column 304 to release the rod sleeve 5. After the rod sleeve 5 is released, it swings down to an empty position by relying on the gravity of the rod sleeve 5 and the measuring rod 501.

[0049] Preferably, a threaded sleeve 303 is welded on the left side of the bottom of the vertical support bracket 3, and a drive motor 4 is fixedly installed on the left side of the rear end of the protruding mounting plate, and a lead screw is axially mounted on the drive motor 4, and the lead screw and the threaded sleeve 303 are screwed through and fitted together. Through the lead screw, the drive motor 4 can rotate forward and reverse to drive the vertical support bracket 3 and the vertical support bracket 3 to slide forward and backward for transmission or feeding.

[0050] Based on the first embodiment, the second embodiment:

[0051] In the use state, the rod sleeve 5 is kept horizontal, and the guide wheel at the head end of the measuring rod 501 is in rolling contact with the roller 2, and the guide wheel and the grinding wheel 301 are both against the circumferential end surface of the roller 2 at the same horizontal height (refer to Figure 1 ), the measuring rod 501 is used in conjunction with the rod sleeve 5 to measure the radius of the grinding wheel 301, and the T-shaped slider 5011 slides back and forth along the U-shaped scale plate 505 for reference readings;

[0052] When the outer diameter of the grinding wheel 301 gradually decreases after being worn, the driving motor 4 drives the vertical support 3 and the grinding wheel 301 to feed forward to compensate for the wear of the grinding wheel 301, so that the grinding wheel 301 always maintains friction contact with the roller 2 for normal and continuous grinding processing. As the outer diameter of the grinding wheel 301 continues to decrease and the grinding wheel 301 continues to move forward, the measuring rod 501 and the T-shaped slide block 5011 are gradually pushed back and slid backward, so as to realize real-time measurement and monitoring of the radius (wear amount) of the grinding wheel 301.

[0053] The rod sleeve 5 is directly held by hand and swung upward to a horizontal measurement state. When the rod sleeve 5 is driven to swing upward, the head end of the measuring rod 501 comes into contact with the installed roller 2. Through the circular arc surface guiding principle of the roller 2, the measuring rod 501 can be pushed backward to slide into an empty space, avoiding obstruction to the upward swing of the rod sleeve 5.

[0054] Working principle: When in use, the rod sleeve 5 is kept horizontal, and the guide wheel and the grinding wheel 301 are both against the circumferential end surface of the roller 2 at the same level (refer to Figure 1 ), the measuring rod 501 is used in conjunction with the rod sleeve 5 to measure the radius of the grinding wheel 301, and the T-shaped slider 5011 slides back and forth along the U-shaped scale plate 505 for reference readings;

[0055] When the outer diameter of the grinding wheel 301 gradually decreases after being worn, the driving motor 4 drives the vertical support 3 and the grinding wheel 301 to feed forward to compensate for the wear of the grinding wheel 301, so that the grinding wheel 301 always maintains friction contact with the roller 2 for normal and continuous grinding processing. As the outer diameter of the grinding wheel 301 continues to decrease and the grinding wheel 301 continues to move forward, the measuring rod 501 and the T-shaped slide block 5011 are gradually pushed back and slid backward, so as to realize real-time measurement and monitoring of the radius (wear amount) of the grinding wheel 301.

[0056] The rod sleeve 5 is rotatably installed with the mounting column 304. When the grinding wheel 301 or the rolling roller 2 is disassembled and replaced in an idle state, it can be swung downward to free up the loading and unloading operation space on the front side and the left and right sides thereof, so as to avoid obstruction to the disassembly and transfer of the grinding wheel 301 or the rolling roller 2, and avoid causing the body thereof to be bent or broken by collision. Through the L-shaped plug rod 601, the positioning member 6 can insert and position the rod sleeve 5 in a horizontal measurement use state. By pushing the L-shaped push plate forward, the L-shaped plug rod 601 can be driven to be pulled away from the mounting column 304 to release the rod sleeve 5. After being released, the rod sleeve 5 swings downward to an empty position by the gravity of the rod sleeve 5 and the measuring rod 501.

[0057] The rod sleeve 5 is directly held by hand and swung upward to a horizontal measurement state. When the rod sleeve 5 is driven to swing upward, the head end of the measuring rod 501 comes into contact with the installed roller 2. Through the circular arc surface guiding principle of the roller 2, the measuring rod 501 can be pushed backward to slide into an empty space, avoiding obstruction to the upward swing of the rod sleeve 5.
