Description

Technical Field

[0001] This utility model relates to the technical field of machining, and in particular to a grinding device for cold-hardened rolling mill production. Background Technology

[0002] Cold-hardened rolls are cast iron rolls manufactured through a chilling casting process, widely used in the rolling of plates and strips. During production, cold-hardened rolls require grinding to improve their surface roughness. In the prior art, utility model patent application number 202420537349.8 discloses a high-precision roll grinding device, mainly composed of a base plate, a fixed seat, and grinding stones. In use, the roll is clamped and fixed by the fixed seat, and then ground by the grinding stones. However, this device has the following problems: during the grinding process, the surface roughness of the roll can only be judged visually, relying heavily on the worker's experience, making it inconvenient to use and impractical. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a cold-hardened roll production grinding device that can measure the surface roughness of the roll through a measuring mechanism during the roll grinding process, reducing the reliance on worker experience and offering high reliability and practicality.

[0004] This utility model discloses a grinding device for cold-hardened rolling mill rolls, comprising a base plate, a clamping mechanism, a grinding mechanism, and a measuring mechanism. The clamping mechanism is mounted on the base plate and has a clamping and fixing function. The measuring mechanism is also mounted on the base plate and has a measuring function. The grinding mechanism is located above the clamping mechanism and has a grinding function. When grinding the roll, the roll is first clamped and fixed by the clamping mechanism, and then the outer diameter of the roll is ground by the grinding mechanism to reduce the surface roughness of the roll. After the grinding is completed, the surface roughness of the roll is measured by the measuring mechanism. If the surface roughness of the roll is qualified, the roll is disassembled; if the surface roughness is unqualified, the roll is re-ground. The device allows for measurement of the surface roughness of the roll during the grinding process, reducing reliance on worker experience and offering high reliability and practicality.

[0005] Preferably, the clamping mechanism includes a support plate, a servo motor, a rotating shaft, and a three-jaw chuck. The support plate is fixedly mounted on the upper part of the base plate, the servo motor is fixedly mounted on the support plate, the rotating shaft is rotatably mounted on the support plate, the input end of the rotating shaft is connected to the servo motor, and the three-jaw chuck is fixedly mounted on the right end of the rotating shaft. When grinding the roll, the left part of the roll is clamped and fixed by the three-jaw chuck, and then the upper part of the roll is ground by the grinding mechanism. At the same time, the servo motor is turned on, and the servo motor drives the three-jaw chuck to rotate the roll through the rotating shaft. During the rotation, the roll is evenly ground by the grinding mechanism, which facilitates the grinding of the roll.

[0006] Preferably, the grinding mechanism includes a hoisting frame, an electric slide rail A, a sliding plate, a hydraulic cylinder A, a lifting rod, and a grinding machine. The electric slide rail A is fixedly installed at the lower end of the hoisting frame, the sliding plate is installed on the electric slide rail A, and the electric slide rail A is used to move the sliding plate left and right. The hydraulic cylinder A is fixedly installed at the lower end of the sliding plate, the upper end of the lifting rod is connected to the output end of the hydraulic cylinder A, and the grinding machine is fixedly installed at the lower end of the lifting rod. The hoisting frame is fixedly hoisted on the support in the workshop. When grinding the outer surface of the roll, the hydraulic cylinder A is opened, and the hydraulic cylinder A lowers the grinding machine through the lifting rod. During the descent, the grinding machine contacts the outer surface of the roll and grinds the outer surface of the roll. At the same time, the electric slide rail A can be opened, and the electric slide rail A moves the hydraulic cylinder A, the lifting rod, and the grinding machine in the left and right directions through the sliding plate, so that the grinding machine grinds the left and right sides of the roll evenly, which facilitates the grinding of the roll.

[0007] Preferably, the measuring mechanism includes an electric slide rail B, a moving block, a support column, a hydraulic cylinder B, a sliding rod, and a roughness detector. The electric slide rail B is fixedly installed at the front of the upper part of the base plate. The moving block is installed on the electric slide rail B, which is used to move the moving block left and right. The support column is fixedly installed at the upper end of the moving block. The hydraulic cylinder B is fixedly installed at the upper end of the support column. A sliding rod is provided at the output end of the hydraulic cylinder B. The roughness detector is fixedly installed at the front end of the sliding rod. When it is necessary to measure the roughness of the outer surface of the roll, the hydraulic cylinder B is opened. The hydraulic cylinder B moves the roughness detector forward through the sliding rod, thereby bringing the roughness detector into contact with the surface of the roll. The roughness of the roll surface can then be measured by the roughness detector. Furthermore, the electric slide rail B can be opened, and the electric slide rail B can adjust the position of the support column in the left and right directions through the moving block. This allows the hydraulic cylinder B, the sliding rod, and the roughness detector to adjust their positions in the left and right directions, enabling the roughness detector to measure the roughness of any part of the roll in the left and right directions. This facilitates the detection of the surface roughness of the roll and improves convenience.

[0008] Preferably, the assembly also includes an electric slide rail C, a movable plate, a vertical plate, a rotating shaft, and a center.

The rotating shaft is coaxial with the rotating shaft. The right end of the roll is provided with a tapered hole that cooperates with the center. When clamping and fixing the roll, the electric slide rail C is opened. The electric slide rail C, through the movable plate, causes the vertical plate to drive the rotating shaft and the center to move to the left, thereby allowing the left part of the center to enter the tapered hole on the right side of the roll. The center fixes the right side of the roll, improving the stability of the roll during processing.

[0009] Preferably, the servo motor is equipped with a leakage current protector.

[0010] Preferably, the hydraulic cylinder B is equipped with a dust cover.

[0011] Compared with the prior art, the advantages of this utility model are: during the grinding process of the roll, the surface roughness of the roll can be measured by a measuring mechanism, which reduces the dependence on the worker's experience and has high reliability and practicality.

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0019] like Figures 1 to 5 The present invention relates to a grinding device for cold-hardened rolling mill rolls, comprising a base plate 1, a clamping mechanism, a grinding mechanism, and a measuring mechanism. The clamping mechanism is mounted on the base plate 1 and has a clamping and fixing function. The measuring mechanism is mounted on the base plate 1 and has a measuring function. The grinding mechanism is located above the clamping mechanism and has a grinding function. When grinding the rolling mill roll 23, the rolling mill roll 23 is first clamped and fixed by the clamping mechanism, and then the outer diameter of the rolling mill roll 23 is ground by the grinding mechanism to reduce the surface roughness of the rolling mill roll 23. After the grinding of the rolling mill roll 23 is completed, the surface roughness of the rolling mill roll 23 is measured by the measuring mechanism. If the surface roughness of the rolling mill roll 23 is qualified, the rolling mill roll 23 is disassembled. If the surface roughness of the rolling mill roll 23 is unqualified, the rolling mill roll 23 is re-ground. During the grinding process of the rolling mill roll 23, the surface roughness of the rolling mill roll 23 can be measured by the measuring mechanism, which reduces the dependence on the worker's experience and has high reliability and practicality.

[0020] like Figure 1 The clamping mechanism includes a support plate 2, a servo motor 3, a rotating shaft 4, and a three-jaw chuck 5. The support plate 2 is fixedly installed on the upper end of the base plate 1, the servo motor 3 is fixedly installed on the support plate 2, the rotating shaft 4 is rotatably installed on the support plate 2, and the input end of the rotating shaft 4 is connected to the servo motor 3. The three-jaw chuck 5 is fixedly installed on the right end of the rotating shaft 4. When grinding the roll 23, the left part of the roll 23 is clamped and fixed by the three-jaw chuck 5. Then, the upper part of the roll 23 is ground by the grinding mechanism. At the same time, the servo motor 3 is turned on. The servo motor 3 drives the three-jaw chuck 5 to rotate the roll 23 through the rotating shaft 4. The roll 23 is evenly ground by the grinding mechanism during the rotation process, which facilitates the grinding of the roll 23.

[0021] like Figure 1 and Figure 3The grinding mechanism includes a hoisting frame 6, an electric slide rail A7, a sliding plate 8, a hydraulic cylinder A9, a lifting rod 10, and a grinding machine 11. The electric slide rail A7 is fixedly installed at the lower end of the hoisting frame 6, and the sliding plate 8 is installed on the electric slide rail A7. The electric slide rail A7 is used to move the sliding plate 8 left and right. The hydraulic cylinder A9 is fixedly installed at the lower end of the sliding plate 8, and the upper end of the lifting rod 10 is connected to the output end of the hydraulic cylinder A9. The grinding machine 11 is fixedly installed at the lower end of the lifting rod 10. The hoisting frame 6 is fixedly hoisted on the workshop's support structure. When the rolling mill... When grinding the outer surface of roller 23, hydraulic cylinder A9 is opened. Hydraulic cylinder A9 lowers grinding machine 11 via lifting rod 10. During the descent, grinding machine 11 contacts the outer surface of roller 23 and grinds the outer surface of roller 23. At the same time, electric slide rail A7 can be opened. Electric slide rail A7 moves hydraulic cylinder A9, lifting rod 10 and grinding machine 11 in the left and right directions via sliding plate 8, so that grinding machine 11 grinds the left and right sides of roller 23 evenly, which facilitates grinding of roller 23.

[0022] like Figure 1 and Figure 4 The measuring mechanism includes an electric slide rail B12, a moving block 13, a support column 14, a hydraulic cylinder B15, a sliding rod 16, and a roughness detector 17. The electric slide rail B12 is fixedly installed on the front part of the upper end of the base plate 1. The moving block 13 is installed on the electric slide rail B12, which is used to move the moving block 13 left and right. The support column 14 is fixedly installed on the upper end of the moving block 13. The hydraulic cylinder B15 is fixedly installed on the upper end of the support column 14. The output end of the hydraulic cylinder B15 is equipped with a sliding rod 16. The roughness detector 17 is fixedly installed at the front end of the sliding rod 16. When it is necessary to measure the roughness of the outer surface of the roll 23, the hydraulic cylinder B15 is opened. Hydraulic cylinder B15 moves the roughness detector 17 forward via sliding rod 16, bringing it into contact with the surface of roll 23. The roughness of the roll 23 surface can then be measured using the roughness detector 17. Furthermore, the electric slide rail B12 can be opened, and the position of the support column 14 in the left-right direction can be adjusted via moving block 13. This allows the hydraulic cylinder B15, sliding rod 16, and roughness detector 17 to be adjusted in the left-right direction, enabling the roughness detector 17 to measure the roughness of any part of the roll 23 in the left-right direction.

[0024] Based on Example 1, an electric slide rail C18, a moving plate 19, a vertical plate 20, a rotating shaft 21, and a center 22 are added. The electric slide rail C18 is fixedly installed on the upper end of the base plate 1.

The center 22 is fixedly installed on the left end of the rotating shaft 21, and the rotating shaft 21 is coaxial with the rotating shaft 4. The right end of the roll 23 is provided with a tapered hole that cooperates with the center 22. When the roll 23 is clamped and fixed, the electric slide rail C18 is opened. The electric slide rail C18 causes the vertical plate 20 to move the rotating shaft 21 and the center 22 to the left through the moving plate 19, so that the left part of the center 22 enters the tapered hole on the right side of the roll 23. The right side of the roll 23 is fixed by the center 22, which improves the stability of the roll 23 during the processing.

[0025] It should be added that: the roll 23 in this case has a machining allowance in the length direction. When the roll 23 is polished, the part of the roll 23 that is clamped and fixed by the three-jaw chuck 5 cannot be polished. This part will be cut off in the subsequent processing and will not affect the subsequent use of the roll 23.
