Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a CNC roll grinding machine. Background Technology

[0002] In the roll manufacturing and repair industry, CNC roll grinding machines are key equipment, and their performance directly affects the processing quality, production efficiency, and service life of the rolls. With the increasing demands for roll precision in industrial production, and the increasingly stringent environmental and occupational health standards, existing CNC roll grinding machines are gradually revealing some problems that urgently need to be addressed in practical applications.

[0003] During the long-term operation of CNC roll grinding machines, the grinding wheel holder gradually changes size due to continuous friction and wear. However, existing detection methods have significant shortcomings. Manually disassembling and frequently inspecting the wear of the grinding wheel is not only complex and time-consuming but also requires machine downtime, greatly impacting production efficiency and increasing costs. Furthermore, while some existing detection devices can achieve a certain degree of wear detection, they often suffer from complex structures and large space requirements. Some detection devices may interfere with the main operation of the grinding machine during installation and use, affecting its normal operation. The inability to detect changes in grinding wheel size in a timely and accurate manner often leads to decreased machining accuracy, making it difficult to effectively guarantee the machining quality and consistency of the roll surface, thus affecting the roll's performance. Performance and lifespan during subsequent use: During the grinding process, the high-speed rotation of the grinding wheel and its contact with the surface of the rollers generate a large amount of dust. The dust concentration in the grinding area is usually 80-120 mg / m³, while the international occupational safety standard limit is only 5 mg / m³. The actual concentration exceeds the limit by 16 to 24 times, which is considered a serious violation. This dust not only accumulates inside the equipment, causing pollution and wear to precision structures such as moving mechanisms and sensing components, reducing the reliability and lifespan of the equipment, but also spreads in the workshop environment, seriously deteriorating the working conditions of the workers. Long-term inhalation of this dust will cause great harm to the health of the workers and increase the risk of occupational diseases. Utility Model Content

A first locking pin is slidably installed in the first sliding hole. A chuck is fixedly installed on one side of the first locking pin. A pull ring is installed on the side of the first locking pin near the chuck. A return spring is fixedly installed between the chuck and the marker rod.

[0013] Preferably, the limiting block has an installation cavity, the second locking pin is slidably installed in the installation cavity, a stop block is fixedly installed on the second locking pin, the stop block is slidably installed in the installation cavity, a pressure spring is fixedly installed on one side of the second locking pin, the other side of the pressure spring is fixedly installed on one side inside the installation cavity, and a handle is fixedly installed between the two second locking pins.

[0014] Preferably, a button is provided on one side of the connecting block, the button is electrically connected to the nozzle, and a push rod is installed on one side of the grinding wheel seat, the push rod abutting against the button.

[0015] The beneficial effects of this utility model are:

[0016] 1. This type of CNC roll grinding machine, by incorporating a measuring component, allows for real-time and intuitive detection and recording of wear during the long-term operation of the grinding wheel holder. This effectively prevents the decline in machining accuracy caused by undetected changes in grinding wheel dimensions, ensuring the machining quality and consistency of the roll surface. The measuring component is driven by a hydraulic cylinder, enabling rapid extension and retraction positioning without interfering with the main operation of the grinding machine. Combined with a slidable scale, marker, and graduated strip structure, it achieves precise measurement of the distance between the grinding wheel holder and the measuring reference. The operator only needs to read the position of the marker strip on the scale line to determine the current wear level of the grinding wheel, simplifying operation. It is convenient and highly repeatable; the pointer is connected to the rotating disk and fixed disk through a sliding lock and spring reset mechanism, which not only allows for quick unlocking after measurement, but also enables the pointer to be compactly stored against the scale body by rotation. It also ensures the compactness and safety of the device when not in use, avoiding collision damage caused by exposed pointers, and improving the integrity and durability of the equipment structure. At the same time, the design of the measuring components reduces the complexity of frequent manual disassembly and measurement, reduces downtime, and improves detection efficiency. It significantly enhances the convenience of maintenance, detection accuracy and intelligence of the grinding machine during long-term continuous operation, and is an important auxiliary mechanism to ensure the efficient and stable operation of CNC roll grinding machines.

[0017] 2. This type of CNC roll grinding machine, equipped with a dust suppression component, can automatically activate a water spray dust suppression function during the grinding process. When the grinding wheel seat approaches the mounting base, a push rod located on one side of the grinding wheel seat automatically triggers a button on the connecting block, causing the nozzle to automatically spray a mist of water to cover the processing area. This effectively suppresses the large amount of dust generated by the high-speed rotation of the grinding wheel and its contact with the roll surface, preventing dust accumulation inside the equipment and causing contamination and wear on precision structures such as moving mechanisms and sensing components, thereby improving the reliability and service life of the equipment. It also significantly reduces the spread of dust in the workshop environment, effectively improving the working conditions of operators and reducing occupational health risks caused by dust inhalation. Furthermore, the dust suppression component features an adjustable connecting block structure, which, in conjunction with a sliding groove, limit block, and second locking pin on the mounting base, locks the nozzle position via a handle control, ensuring that the nozzle does not shift position due to equipment vibration during operation. This enhances the stability and reliability of the dust suppression function, further improving the overall automation level, safety performance, and environmental protection of the grinding machine.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] like Figures 1 to 5 As shown, a CNC roll grinding machine includes: a grinding machine body 1, with a grinding wheel holder 2 disposed on one side of the grinding machine body 1; a measuring component, which is installed on one side of the grinding machine body 1 and is used to monitor the wear and consumption of the grinding wheel holder 2; and a dust suppression component, which is installed on one side of the grinding machine body 1 and is used to reduce dust.

[0029] This CNC roll grinding machine uses the grinding machine body 1 as the overall structural support and processing foundation. A grinding wheel holder 2 is provided on one side of the grinding machine body 1 for precision grinding of the roll surface. During the processing, the grinding wheel holder 2 will wear down over time, affecting the processing accuracy. Therefore, a measuring component is provided. The measuring component is installed on one side of the grinding machine body 1 to monitor the wear of the grinding wheel holder 2 at any time. At the same time, in order to avoid the large amount of dust generated by the high-speed rotation of the grinding wheel during the processing, which affects the operation of the equipment and the processing environment, a dust suppression component is also provided on one side of the grinding machine body 1. The dust suppression component can be activated simultaneously during the processing to effectively reduce dust in the processing area by spraying water mist, ensuring the cleanliness of the equipment and the health of the operators, thereby achieving efficient, precise and environmentally friendly roll grinding.

[0030] like Figure 1 , Figure 2 , Figure 3As shown, the measuring assembly includes a hydraulic cylinder 3 mounted on one side of the grinding machine body 1. A mounting base 4 is installed at the output end of the hydraulic cylinder 3. A snap-fit ​​seat 7 is fixedly mounted on one side of the mounting base 4. A scale 8 is snapped onto one side of the snap-fit ​​seat 7. A scale rod 9 is slidably mounted on one side of the scale 8. The long side of the scale rod 9 abuts against the lowest point of the outer circumference of the grinding wheel seat 2. A second groove 21 is formed on one side of the scale 8. A slider 20 is slidably mounted in the second groove 21. A connecting plate 16 is fixedly mounted on one side of the slider 20. A fixed plate 18 is fixedly mounted on one side of the connecting plate 16. A rotating disk 15 is fixedly mounted on one side of the scale rod 9. The disk 15 is rotatably connected to the fixed disk 18; a plurality of second sliding holes 17 are provided on one side of the connecting plate 16, and a first sliding hole 14 is provided on the marker 9. A first locking pin 11 is slidably installed in the first sliding hole 14. A chuck 12 is fixedly installed on one side of the first locking pin 11. A pull ring 10 is installed on the side of the first locking pin 11 near the chuck 12. A return spring 13 is fixedly installed between the chuck 12 and the marker 9. The return spring 13 is sleeved on the outside of the first locking pin 11. The first locking pin 11 is adapted to the second sliding holes 17; a marker strip 19 is fixedly installed on one side of the connecting plate 16. The marker strip 19 is adapted to the scale on the surface of the ruler 8.

[0031] When it is necessary to measure the wear degree of the grinding wheel holder 2, first shut down the grinding machine body 1. At this time, the grinding wheel holder 2, which is located on one side of the grinding machine body 1, will stop working. Then, start the hydraulic cylinder 3 to push the mounting seat 4 installed at its output end forward, thereby moving the snap-fit ​​seat 7 and the snap-fit ​​scale 8 fixed on the mounting seat 4 together, so that the scale 8 moves forward to a position aligned with the grinding wheel holder 2. Subsequently, the operator manually pushes the slider 20 set in the second slide groove 21 on one side of the scale 8, which moves the connecting plate 16, fixed disk 18 and other components fixedly connected to the slider 20 together, so that the scale rod 9 connected to the rotating disk 15 slowly extends until the long side of the scale rod 9 abuts against the lowest point of the outer circumference of the grinding wheel holder 2. At this time, the scale rod 9 is fixed in relative position due to abutting against the grinding wheel holder 2, and the position of the scale bar 19 on the connecting plate 16 is fixed. It is thus determined that by observing the scale position of the scale bar 19 on the surface of the scale 8, the wear data can be read intuitively, and the actual wear degree of the grinding wheel seat 2 can be judged. After the measurement is completed, if the scale 8 is no longer used for monitoring, the pull ring 10 set on the first locking pin 11 is pulled to disengage the first locking pin 11 from the second sliding hole 17 on one side of the connecting plate 16, thereby releasing the fixed state and allowing the scale bar 9 to rotate relative to it. At this time, the scale bar 9 is rotated to keep it parallel to the body of the scale 8, thereby achieving compact storage of the structure. After releasing the pull ring 10, under the elastic force of the return spring 13, the first locking pin 11 is pushed into another spare second sliding hole 17 and completed repositioning and locking, thereby realizing the initial state reset and storage preparation of the measuring component, providing convenience for the next use and ensuring the reliability and reusability of the entire device.

[0032] like Figure 4 , Figure 5 As shown, the dust suppression assembly includes a connecting block 6 slidably mounted on one side of the mounting base 4. First sliding grooves 5 are provided on both symmetrical sides of the mounting base 4. The connecting block 6 is slidably mounted within the first sliding grooves 5. A connecting strip 22 is fixedly mounted on one side of the connecting block 6, and a nozzle 23 is provided on the connecting strip 22. A limiting block 30 is fixedly mounted on one side of the mounting base 4. Two second locking pins 27 are slidably mounted within the limiting block 30. Two locking holes 32 are symmetrically provided on the connecting block 6, and the second locking pins 27 are adapted to the locking holes 32. An installation cavity is provided within the limiting block 30. 31. The second locking pin 27 is slidably installed in the mounting cavity 31. A stop block 29 is fixedly installed on the second locking pin 27. The stop block 29 is slidably installed in the mounting cavity 31. A pressure spring 28 is fixedly installed on one side of the second locking pin 27. The other side of the pressure spring 28 is fixedly installed inside the mounting cavity 31. A handle 26 is fixedly installed between the two second locking pins 27. A button 25 is provided on one side of the connecting block 6. The button 25 is electrically connected to the nozzle 23. A push rod 24 is installed on one side of the grinding wheel seat 2. The push rod 24 abuts against the button 25.

[0033] During the grinding process, when the dust suppression function needs to be activated to inhibit dust diffusion, the mounting base 4 installed at its output end moves towards the grinding wheel seat 2 as the hydraulic cylinder 3 moves. During this process, the push rod 24 located on one side of the grinding wheel seat 2 gradually approaches and eventually contacts the button 25 installed on the connecting block 6. When the push rod 24 contacts the button 25 and generates a certain pressure, the button 25 is triggered, thereby generating an electrical signal control. The nozzle 23, which is electrically connected to it, begins water spraying. The sprayed water mist or liquid directly acts on the grinding wheel processing area, effectively suppressing the large amount of dust generated by the high-speed rotation of the grinding wheel, playing a significant dust suppression role and improving the working environment. The connecting block 6 Installed in the first sliding groove 5 on both sides of the mounting base 4 by sliding, the operator can use the handle 26 to drive the second locking pin 27 to slide inward, disengaging it from the locking hole 32 on the connecting block 6, thereby unlocking the position of the connecting block 6 and realizing the movement or adjustment of the nozzle 23; after releasing the handle 26, under the action of the pressure spring 28, the second locking pin 27 slides back into the locking hole 32 through the stop block 29, completing the repositioning and fixing, thereby ensuring the stability of the spray angle and position of the nozzle 23, ensuring the continuity and reliability of the dust suppression effect, and at the same time preventing the connecting block 6 from being displaced due to vibration during operation, further improving the overall operational safety and automation level of the device.
