Description

Technical Field

[0001] This utility model relates to a grinding device for copper strip rolling rolls, and more particularly to a grinding device for copper strip rolling rolls. Background Technology

[0002] Copper strip, a key metallic material commonly used in the electronics, electrical, and communications industries, has a significant impact on subsequent processing techniques and product performance due to its surface quality. To ensure the surface finish and geometric accuracy of the rolls used in copper strip rolling, regular grinding is typically required. During grinding, the rolls must maintain a stable rotational posture and spatial position to ensure grinding uniformity and processing accuracy. Therefore, efficient and stable grinding devices for rolls have become an important research area in the supporting technologies of rolling equipment.

[0003] Existing roll grinding devices typically employ a pair of opposing ends, clamping both ends of the roll with two oppositely positioned abutting ends. A drive device rotates the roll, thereby achieving the grinding process on its outer surface. This structure generally uses the abutting ends with two collinear rotation axes as the rotation reference. The roll is driven to rotate based on this reference and contacts the grinding device on its surface to complete the surface treatment.

[0004] However, in order to ensure smooth roll rotation, existing grinding devices are prone to radial displacement or axial movement of the rolls during actual operation, affecting the grinding effect. Therefore, to further improve the stability and processing quality of roll grinding, a new roll grinding device for copper strip rolling is proposed to solve the above problems.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0047] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0048] See Figure 1A preferred embodiment of this application provides a grinding device for copper strip rolling rolls. This grinding device is suitable for surface finishing of copper strip rolls, and is particularly suitable for high-precision grinding applications requiring guaranteed roll rotational stability and lateral restraint. The grinding device mainly includes a top-mounting mechanism 10 and at least one side-mounting mechanism 20. The various structural components cooperate to provide multi-directional support, positioning, and rotation control for the roll. The top-mounting mechanism 10 includes a first abutment end 110 and a second abutment end 120 that are controlled to rotate. The second abutment end 120 moves in a controlled manner toward or away from the first abutment end 110 and rotates in a controlled manner. The second abutment end 120 rotates synchronously with the first abutment end 110, and the rotation axis of the second abutment end 120 is collinear with the rotation axis of the first abutment end 110. The side-top mechanism 20 includes a first ejector end 210 and a second ejector end 220. The first ejector end 210 is controlled to move in a direction perpendicular to the movement direction of the second abutment end 120, and the angle between the first ejector end 210 and the horizontal plane is greater than 15° and less than 45°. The second ejector end 220 is also controlled to move in a direction perpendicular to the movement direction of the second abutment end 120, and the angle between the second ejector end 220 and the vertical plane is greater than 15° and less than 45°. The angle between the second ejector end 220 and the first ejector end 210 is any value between 85° and 95°. When the grinding device is in operation, the first abutting end 110 and the second abutting end 120 abut against the two ends of the roller, so that the roller rotates synchronously with the first abutting end 110. The rotation axis of the first abutting end 110 is collinear with the axis of the roller. The second ejection end 220 is located between the roller and the ground. The first ejection end 210 and the second ejection end 220 are both controlled to move to abut against the side of the roller to limit the lateral movement of the roller when it rotates.

[0049] The aligning mechanism 10 includes a first abutment end 110 and a second abutment end 120. The first abutment end 110 is mounted on one end of the grinding device via a support structure and is configured to rotate controllably, with its axis serving as the reference for the rotation of the entire roll. The second abutment end 120 is located on the side opposite to the first abutment end 110 and is controlled by a linear drive device to move along the axial direction between itself and the first abutment end 110, thereby adapting to the clamping requirements of rolls of different lengths. It is also equipped with a rotating structure to allow it to rotate synchronously with the first abutment end 110. The rotation axes of the two abutment ends remain collinear, thus ensuring rotational accuracy and stability when driving the roll to rotate.

[0050] At least one side-supporting mechanism 20 is disposed in the lateral region of the roll axis to provide radial support for the roll. The side-supporting mechanism 20 includes a first ejector end 210 and a second ejector end 220. The first ejector end 210 is controlled to move by a drive unit disposed on an inclined guide rail or articulated arm assembly. Its direction of movement is perpendicular to the direction of movement of the second abutment end 120 and forms an acute angle with the horizontal plane, which is greater than 15 degrees and less than 45 degrees, facilitating reliable support of the area above the roll side. The second ejector end 220 moves in the same direction as the second abutment end 120 and forms an acute angle with the vertical direction, which is also greater than 15 degrees and less than 45 degrees. The second ejector end 220 is located below the roll and provides support to the bottom side of the roll. The included angle between the two ejector ends is controlled within a near-vertical range, i.e., between 85 and 95 degrees, thereby jointly limiting the roll in two different but approximately perpendicular directions.

[0051] When the device is in operation, the second abutment end 120 is moved to clamp and fix the roll, while the first abutment end 110 drives the roll to rotate, forming a rotation reference. The two ejector ends of the side-top mechanism 20 move towards the side of the roll from the aforementioned angle direction and form contact support with the roll sidewall, thereby preventing radial displacement of the roll during rotation and ensuring stable roll rotation posture, providing a reliable support platform for subsequent grinding operations. The entire device can be integrated into a grinding table, is suitable for ordinary factory environments, requires no special temperature and humidity control, and its adaptability can be adjusted according to the roll size, exhibiting good versatility and compatibility.

[0052] In practical use, the device can also be used in conjunction with a laser measurement module or a displacement sensing system to dynamically monitor the position and rotation of the rolls, thereby further improving positioning accuracy. For rolls of different materials or weights, an ejector assembly with a buffer structure or an elastic support system can be selected to reduce the impact on the roll surface.

[0053] In this embodiment, by introducing at least one side-top mechanism 20 with specific angle clamping characteristics on the basis of the top-top mechanism 10, the side-top mechanism 20 provides lateral limiting support for the roll from the upper and lower sides through two ejector ends with approximately perpendicular angles between their moving directions. Therefore, it effectively solves the problem of radial displacement or movement of the roll during grinding caused by relying solely on the top-top structure in the prior art. This achieves the technical effect of improving grinding stability, processing accuracy and the applicability of the device without affecting the roll's rotational freedom.

[0054] In some embodiments, see Figure 2The side-top mechanism 20 in the copper strip rolling roll grinding apparatus further includes an ejector end structure with a contact plane to achieve more stable and reliable roll limiting support. The first ejector end 210 includes a first plane 211, which is perpendicular to the direction of movement of the first ejector end 210, and is configured to abut against the side of the roll when the grinding apparatus is in operation. The second ejector end 220 includes a second plane 221, which is perpendicular to the direction of movement of the ejector end, and is configured to abut against the side of the roll when the grinding apparatus is in operation.

[0055] Specifically:

[0056] The first ejector end 210 is provided with a first plane 211, which extends along a direction perpendicular to the movement direction of the first ejector end 210, forming an integral surface that fits against the side of the roll. This structure provides a large contact area without damaging the roll surface by contacting the plane with the cylindrical surface, thereby enhancing the lateral positioning stability of the roll.

[0057] Similarly, the second ejector end 220 also includes a second plane 221, which is perpendicular to the direction of movement of the second ejector end 220. When the grinding device is in operation, the second plane 221 is used to form a supporting contact with the side wall area near the bottom of the roll. Since the second ejector end 220 is generally located between the roll and the ground, and its supporting direction is upward, the presence of the second plane 221 not only helps to provide anti-sinking support force for the roll, but also forms a clamping and limiting structure with the first plane 211, providing effective constraint on the radial movement of the roll during rotation.

[0058] The first plane 211 and the second plane 221 can be configured using an adjustable-angle connection structure or a ball joint linkage mechanism on the processing platform, ensuring relatively complete and symmetrical contact on the sides of rolls of different specifications. This type of structure also facilitates disassembly and maintenance. The limiting plane material with different hardness or surface treatment can be selected according to the roll material, such as a metal substrate with an elastic layer or a ceramic contact surface coated with a wear-resistant coating, to prevent damage to the roll surface after long-term use.

[0059] During operation, after the top-clamping mechanism 10 clamps the roll, the two ejector ends extend forward in their respective directions under controlled drive until the first plane 211 contacts the upper side of the roll and the second plane 221 contacts its lower side. The synergistic effect of the two planes effectively prevents the lateral movement of the roll. Even under high-speed rotation or load variation conditions, the roll maintains stability in the axial direction, avoiding a decrease in grinding quality caused by eccentric rotation.

[0060] This embodiment is applicable to various standard factory environments, requires no special temperature control conditions, has a compact structure, and is easy to integrate into existing copper strip rolling auxiliary equipment systems. For large or extra-long rolls, the radial limiting performance can be further improved by setting up a combination structure of multiple symmetrically arranged first planes 211 and second planes 221.

[0061] In this embodiment, by adopting the technical means of setting a planar contact structure perpendicular to its moving direction on the first ejector end 210 and the second ejector end 220, the first plane 211 and the second plane 221 can contact the upper and lower sides of the roll respectively when the grinding device is working. Therefore, the problem of radial displacement of the roll caused by small contact area of ​​ejector end and unstable support in the prior art is effectively solved, thereby achieving the technical effects of improving the reliability of lateral limit, ensuring grinding accuracy and extending the service life of the device.

[0062] In some embodiments, see Figure 2The side-top mechanism 20 in the copper strip rolling roll grinding device further includes a housing 230 for supporting and guiding the ejection structure and two independently configured ejection assemblies 240 for controlling the movement of the first ejection end 210 and the second ejection end 220, respectively. The housing 230 includes a first guide space 231 and a second guide space 232. The extension direction of the first guide space 231 is parallel to the movement direction of the first ejection end 210, and the extension direction of the second guide space 232 is parallel to the movement direction of the second ejection end 220. The housing 230 has a first opening 2311 communicating with the first guide space 231 and a second opening 2321 communicating with the second guide space 232 on the side near the roll. The ejection assembly 240 includes a controllably rotating lead screw 241, an ejector 242, and an internally threaded tube 243. One lead screw 241 is disposed within the first guide space 231, with its rotation axis parallel to the direction of movement of the first ejector end 210. The other lead screw 241 is disposed within the second guide space 232, with its rotation axis parallel to the direction of movement of the second ejector end 220. One ejector 242 is disposed within the first guide space 231 and is restricted to moving along the extension direction of the first guide space 231. The other ejector 242 is disposed in the second guide space 232 and is restricted to move along the extension direction of the second guide space 232. The first ejector end 210 and the second ejector end 220 are respectively disposed on the side of the two ejector parts 242 facing the corresponding first opening 2311 and second opening 2321. The two internally threaded tubes 243 are connected to the two ejector parts 242 in a one-to-one correspondence, and the two internally threaded tubes 243 are threadedly connected to the two lead screws 241 in a one-to-one correspondence. When the grinding device is in working condition, the first ejector end 210 and the second ejector end 220 disposed on the two ejector parts 242 respectively pass through the first opening 2311 and the second opening 2321 to move outside the housing 230 and abut against the circumference of the roller.

[0063] The housing 230 can be a metal structure, with an overall box-like or block-like structure. It has two independent guide spaces inside: a first guide space 231 and a second guide space 232. The extension direction of the first guide space 231 is consistent with the movement direction of the first ejector end 210, and the extension direction of the second guide space 232 is consistent with the movement direction of the second ejector end 220. The housing 230 has two through-hole structures near the roll: a first opening 2311 communicating with the first guide space 231 and a second opening 2321 communicating with the second guide space 232. These allow the ejector end assembly to extend outward under drive, achieving contact with the side of the roll.

[0064] Each ejector assembly 240 includes a lead screw 241, an internally threaded tube 243, and an ejector 242. The lead screw 241 is a controlled rotating component, with its rotation axis arranged parallel to the movement direction of the corresponding ejector end. The ejector 242 is disposed within a guide space, and its overall shape can be a cylinder, cuboid, or other structure that facilitates force application, allowing restricted movement along the extension direction of the guide space. One end of the ejector 242 is provided with an ejector end component, which extends from inside the housing 230 to the outside during movement, abutting against the side wall of the roll to form a limiting support. The ejector 242 is fixedly connected to the internally threaded tube 243, which forms a threaded engagement structure with the lead screw 241. When the lead screw 241 rotates, it drives the internally threaded tube 243 and its connected ejector 242 to move back and forth, thereby realizing the extension and retraction of the ejector end.

[0065] During operation, the operator activates the drivers of the two lead screws 241 via the control system, causing the lead screws 241 within the first guide space 231 and the second guide space 232 to rotate. The rotation of the lead screws 241 drives the mating internally threaded tube 243 to produce linear displacement, which in turn moves the ejector 242 forward or backward. Once the grinding device is positioned, the two ejector ends 210 and 220 extend through the openings in the housing 230 to the outside of the housing 230, respectively, and contact different sides of the roll, forming a closed structural path that supports and limits the roll from different directions.

[0066] This device structure is suitable for various specifications of rolls. Adaptation to rolls of different lengths and diameters can be achieved simply by adjusting the stroke of the lead screw 241 and the guide space dimensions. The compact transmission structure of the ejector 242 and lead screw 241 facilitates high-precision, multi-angle limit control within limited installation space. Furthermore, the housing 230 can be designed as a side-mounted, bottom-mounted, or rotatable structure according to the actual equipment layout to meet different angle clamping and grinding requirements.

[0067] In specific applications, the lead screw 241 can be configured as an electric servo type for automated adjustment in conjunction with a control system, or as a mechanical manual type, suitable for simplified versions with limited space or where frequent adjustments are not required. Wear-resistant bushings or lubrication layers can also be added to the guide space to improve service life.

[0068] In this embodiment, by employing the guiding structure of the housing 230 in conjunction with the ejector assembly 240 driven by the controlled lead screw 241, the first ejector end 210 and the second ejector end 220 can extend smoothly in different directions and form a stable contact with the side of the roll. Therefore, it effectively solves the problems of poor guiding performance, inaccurate positioning, and inconvenient adjustment of the ejector structure in the prior art, thereby achieving the technical effects of improving lateral positioning accuracy, enhancing the stability of the grinding process, and taking into account both structural compactness and adaptability.

[0069] In some embodiments, the ejector assembly 240 of the copper strip rolling mill grinding apparatus further includes a motor 244 and a transmission assembly 245 to achieve automated drive control of the lead screw 241, thereby improving the accuracy and response efficiency of the ejector end during the limiting process. This structure is suitable for industrial applications requiring high-frequency adjustment or continuous grinding in multiple batches, and is particularly suitable for integration into automated production lines or intelligent grinding systems. The motor 244 includes a controlled-rotation output shaft, which is connected to the lead screw 241 via the transmission assembly 245.

[0070] Specifically:

[0071] The motor 244 can be a stepper motor 244, a servo motor 244, or a micro motor 244 with coded feedback. It is equipped with an output shaft, and its rotation direction and speed are adjusted as needed by the control system. The output shaft of the motor 244 is connected to the lead screw 241 through a transmission assembly 245 to accurately and efficiently transmit the rotational output of the motor 244 to the lead screw 241. The transmission assembly 245 can be a direct coupling, a reduction gear set, or a flexible transmission connection through a synchronous belt pulley mechanism, selected according to different application requirements.

[0072] The motor 244 is fixedly mounted outside the housing 230, forming a stable support with the housing 230 through a connecting seat, preventing vibration during operation from affecting the guiding accuracy. The transmission assembly 245 is located between the motor 244 and the lead screw 241, with its output shaft coaxially connected to the lead screw 241, ensuring that the rotation axis of the lead screw 241 is consistent with the extension direction of the guide space. After the lead screw 241 rotates, it drives the ejector 242 to move forward or backward along the guide space through the internally threaded tube 243 that mates with it. The ejector end on the ejector 242 thus extends controllably out of the opening of the housing 230 and fits against the side of the roll to form a stable limit.

[0073] During operation, the control system issues drive commands according to clamping requirements. After receiving the signal, motor 244 outputs rotational torque, which is transmitted to lead screw 241 via transmission component 245, causing the ejector end to smoothly extend forward to the designated position. When grinding is completed or the roll needs to be released, motor 244 reverses to drive the ejector end to retract, achieving automatic reset, which greatly improves operating efficiency and positioning consistency.

[0074] This ejection structure is particularly suitable for scenarios requiring rapid roll changes or frequent start-stop operations. It can achieve precise position control and status feedback through communication with a host computer, and can also integrate components such as displacement sensors and limit switches to form a vertical closed-loop adjustment system, enhancing system reliability and safety.

[0075] To reduce costs or adapt to a simplified version of the equipment, the motor 244 can be replaced with a pneumatic or hydraulic drive source, the transmission component 245 can be a rack and pinion structure, or a linear drive can be used to replace the traditional lead screw 241 system, thus achieving a feasible alternative solution with similar functions.

[0076] In this embodiment, by employing a technology that drives the lead screw 241 through a motor 244 and a transmission assembly 245, the ejector end can achieve high-precision, automated, and controllable telescopic movement. Therefore, it effectively solves the problems of low adjustment efficiency, inaccurate positioning, and difficulty in integrating an automatic control system in the prior art, thereby achieving the technical effects of improving limit reliability, reducing the frequency of manual intervention, and enhancing the automation level of the equipment.

[0077] In some embodiments, to improve the rotational accuracy and operational stability of the lead screw 241 transmission structure in the ejector assembly 240, the ejector assembly 240 further includes a bearing 247 frame 246 and a bearing 247 structure for providing axial positioning and rotational guidance support for the lead screw 241. The bearing 247 frame 246 is disposed inside the housing 230, and the bearing 247 is disposed within the bearing 247 frame 246, and the bearing 247 is connected to the lead screw 241, thereby restricting the lead screw 241 to rotate about its own axis.

[0078] The bearing 247 holder 246 is disposed inside the housing 230 of the side-top mechanism 20, and can adopt an integral molding structure or a modular installation method. It is connected to the housing 230 by fasteners or positioned by guide rail. The structural shape of the bearing 247 holder 246 matches the inner cavity of the housing 230, and the whole is a ring or nested support structure, which has good rigidity and positioning stability. Its installation position is usually set on the axial extension path of one end or the middle of the lead screw 241, forming a constraint on the rotation axis of the lead screw 241.

[0079] Bearing 247 is installed inside bearing holder 246. High-rigidity, low-friction models such as deep groove ball bearings 247, angular contact bearings 247, or needle roller bearings 247 are preferred. The appropriate model is selected based on the working load and transmission accuracy requirements. A portion of the journal of the lead screw 241 passes through the center hole of the bearing 247. The bearing 247 and the lead screw 241 have a transition fit or interference fit, which provides effective support without affecting the free rotation of the lead screw 241.

[0080] With the above structure, the lead screw 241 can maintain a stable rotational posture within the ejector assembly 240, allowing it to rotate only around its own axis, thus preventing axial wobble or yaw during the drive process. This not only improves the helical transmission efficiency between the lead screw 241 and the internal threaded tube 243, but also extends the service life of the guide structure.

[0081] During operation, when the motor 244 or manual device drives the lead screw 241 to rotate, the bearing 247 provides continuous support for the lead screw 241, ensuring that the rotation axis remains constant. This ensures that the trajectory of the internal thread tube 243 driving the ejector 242 to move forward in a straight line is accurate, avoiding problems such as offset, tilting or jamming of the ejector end caused by the jump of the lead screw 241. It is especially suitable for automatic grinding applications with high requirements for ejection stroke and accuracy.

[0082] This structure is suitable for various installation environments, including the space-constrained interior of a closed housing 230, and also for scenarios requiring frequent replacement or maintenance. Maintenance convenience can be improved by incorporating a removable bearing 247 cover and a quick-release bearing 247 holder 246. In some simplified solutions, the bearing 247 structure can also be replaced with a high-wear-resistant sleeve or a composite sliding bearing 247 to meet low-cost or low-to-medium speed operating requirements.

[0083] In this embodiment, by employing the technical means of setting bearing 247 frame 246 and bearing 247 inside the housing 230, and enabling the lead screw 241 to rotate only around its own axis through the bearing 247, the problem of easy shaking, deviation and unstable transmission efficiency of the lead screw 241 transmission structure during rotation in the prior art is effectively solved. This achieves the technical effect of improving the operating accuracy of the ejector assembly 240, extending the structural life and improving the overall reliability of the device.

[0084] In some embodiments, see Figure 3 To achieve real-time sensing and feedback control of the lateral limiting state, the ejector assembly 240 in the copper strip rolling roll grinding device further includes a pressure sensor 248, used to monitor the force state when the ejector end contacts the side of the roll, thereby determining whether the limiting is in place and whether the contact force is appropriate, and providing real-time data support for the control system. The two pressure sensors 248 are respectively disposed between the first ejector end 210 and the corresponding ejector member 242 and between the second ejector end 220 and the corresponding ejector member 242, to monitor the pressure when the first ejector end 210 and the second ejector end 220 abut against the circumference of the roll.

[0085] Specifically:

[0086] Each ejector assembly 240 is equipped with a set of pressure sensors 248. Two pressure sensors 248 are respectively disposed between the first ejector end 210 and its corresponding ejector component 242, and between the second ejector end 220 and its corresponding ejector component 242. The pressure sensors 248 can be thin-film pressure sensors 248, strain gauge pressure sensors 248, or miniature piezoelectric elements. They are compact in structure, highly responsive, and suitable for integrated installation in confined spaces.

[0087] In terms of structural installation, the pressure sensor 248 can be fixed in the mounting step, limiting groove, or slot structure at the front end of the ejector 242. The ejector end contacts the pressure sensor 248 through an interference fit or a buffer medium to ensure that the sensor can accurately transmit force changes during the pressure application process. During the movement of the ejector end, once it comes into contact with the circumference of the roll and generates a reaction force, this force will act on the pressure sensor 248 axially through the ejector 242, causing the sensor to output a corresponding electrical signal.

[0088] The signal can be amplified and conditioned before being input to the control system of the grinding device for judgment and analysis: if the detected pressure is lower than the set threshold, it is considered that there is no effective contact and the ejector end can continue to move forward; if the pressure is higher than the safety limit, the control system can control the ejector end to stop moving forward or retract to avoid overpressure damage to the roll; if the pressure is within a reasonable range, it can be confirmed that the ejector end has made stable contact with the side of the roll and enters the grinding working state.

[0089] This monitoring mechanism not only improves the reliability and automation of limit actions, but also monitors in real time whether the device fails to limit due to external interference, roll deformation or misoperation during operation. It can also issue alarms or link control to stop the grinding host through preset logic, thereby enhancing system safety.

[0090] Furthermore, this sensing system is suitable for various operating environments, and different types of sensors can be flexibly selected according to the field signal processing system. For high-temperature, high-interference, or oily environments, anti-interference sealed pressure modules can be selected; if the control system supports signal bus transmission, digital sensors can also be arranged in parallel to simplify wiring.

[0091] In some implementation schemes, sensor feedback data can also be used to determine whether the roll is under balanced stress, and to help determine whether there are structural abnormalities such as installation eccentricity or misalignment of the axis, thereby providing early warning and maintenance.

[0092] In this embodiment, by employing a pressure sensor 248 installed between the ejector 242 and the ejector end to monitor the contact pressure between the ejector end and the side of the roll in real time, the problem of not being able to determine the limit contact state, not being able to accurately control the contact force, and not being able to realize fault early warning in the prior art is effectively solved. This achieves the technical effects of improving the limit control accuracy, enhancing the system operation safety, and realizing intelligent monitoring and feedback.

[0093] In some embodiments, such as Figures 2 to 3To further enhance the flexibility and automatic responsiveness of the roll lateral limiting mechanism, the first ejector end 210 and the second ejector end 220 are respectively configured such that when in contact with the circumference of the roll, the first ejector end 210 moves away from the roll side in a direction parallel to the movement of the first ejector end 210, and the second ejector end 220 moves away from the roll side in a direction parallel to the movement of the second ejector end 220. This means that it has a certain passive yielding capability and can automatically retract slightly away from the roll side when there is local disturbance or uneven load on the roll surface, thereby reducing the impact of sudden changes in lateral force on the roll and the structure body, and improving the overall stability and safety of the system.

[0094] Specifically:

[0095] The first ejector end 210 is equipped with a controllable retraction structure along its original direction of movement, such as an elastic limit mechanism, a damping slide structure, or a guide rail assembly with a set limit displacement stroke. When the roll applies excessive reaction force to the first ejector end 210 from its side while rotating or slightly wobbling, the first ejector end 210 can passively retract a small stroke along its direction of movement to absorb the instantaneous impact force caused by the off-center load; when the disturbance is eliminated or the control system feeds back a stable state signal, the first ejector end 210 returns to its original positioning state through restoring force or drive control.

[0096] Similarly, the second ejector end 220 is also configured to move away from the roll along its own direction of movement, responding in a similar manner to the first ejector end 210. Since the second ejector end 220 is usually located below the roll, it experiences greater force from the weight of the roll. Therefore, its retraction mechanism can be designed as a combination of rigidity and flexibility, for example, by incorporating a limit spring, a hydraulic damper, or a micro-stroke servo module to achieve gradual control of the pressure response.

[0097] This structural configuration not only enhances the device's adaptability to abnormal conditions such as different roll diameters, deformations, and eccentricities, but also effectively prevents device deformation and damage caused by assembly tolerances, grinding vibrations, or tightening errors. In some application scenarios, in conjunction with the pressure sensor 248 and feedback system, this retraction action can also serve as an abnormal state trigger signal input to the main control system for linkage alarms, shutdown protection, or automatic adjustment actions.

[0098] This structure has no special requirements for installation space and is suitable for most standard grinding stands and limit devices. In applications where dynamic response is not required, this retraction structure can be replaced with a rigid limit component, making it suitable for low-speed or low-interference environments. To improve durability, the ejector end can be made of high-strength wear-resistant materials, such as surface-hardened steel, stainless steel, or composite engineering plastics. If necessary, a buffer pad or rubber elastic layer can be added at the contact surface to enhance the cushioning effect.

[0099] In this embodiment, by employing a technical means that enables the first ejector end 210 and the second ejector end 220 to move away from the roll side along their moving direction when they come into contact with the circumference of the roll, the problem of side top rigid limit failure, structural damage, or even roll surface scratches caused by roll swaying or disturbance in the prior art is effectively solved. This achieves the technical effects of improving the limit flexible response capability, enhancing equipment durability, and ensuring the continuous stability of the grinding process.

[0100] In some embodiments, see Figure 2 To further enhance the flexibility and precision control of the grinding device in multi-axial position adjustment, a displacement mechanism 30 and a guiding mechanism 40 are proposed to be added to the grinding device for precise movement and guidance of the housing 230. This is particularly suitable for complex curved surfaces, irregularly shaped components, or scenarios with high requirements for grinding trajectory. The displacement mechanism 30 includes a moving end that moves in a controlled manner. The moving end is connected to the housing 230, and the direction of movement of the moving end is perpendicular to the direction of movement of the second abutment end 120. The guiding mechanism 40 includes a linear guide rail and a slider. The linear guide rail is parallel to the direction of movement of the moving end; the slider is disposed on the housing 230 and slides along the linear guide rail, allowing the slider to move along the extension direction of the linear guide rail.

[0101] The displacement mechanism 30 includes a movable end that moves in a controlled direction, perpendicular to the movement direction of the second abutment end 120. The second abutment end 120 is a key component for achieving contact and force transmission between the grinding device and the workpiece, and typically moves in a vertical direction (e.g., up-down direction). The movable end's movement direction is set horizontally, allowing the grinding housing 230 to achieve lateral or longitudinal feed capability on top of vertical grinding, enhancing overall processing adaptability.

[0102] The mobile end is connected to the housing 230 of the grinding device. The grinding housing 230 moves as a whole through the mobile end, and its position can be dynamically adjusted during processing. It plays a key role, especially in processes requiring fine alignment, segmented grinding, or continuous displacement processing. The mobile end can be composed of drive units such as lead screw drive, electric slide, servo slide rail, and pneumatic slide. Its motion parameters can be precisely controlled to achieve smooth adjustment at the millimeter or even micrometer level.

[0103] To ensure good linear guidance performance during operation, this embodiment also includes a guide mechanism 40. The guide mechanism 40 includes a linear guide rail and a slider, with the linear guide rail installed parallel to the movement direction of the moving end. The linear guide rail can be mounted on a support base or structural frame, providing a high-precision linear path.

[0104] The slider is mounted on the housing 230 and slides against the linear guide rail. The slider engages with the guide rail via rollers, balls, or slippers, ensuring smooth movement and repeatability while maintaining low friction. During operation, the slider moves with the housing 230, smoothly advancing along the linear guide rail's extension direction, effectively preventing lateral sway, structural vibration, or guide deviation.

[0105] This guide structure is particularly suitable for automated grinding equipment that operates at high speeds, requires repeated positioning, and involves large strokes. The linear guides and sliders can be made of high-rigidity alloy steel, stainless steel, or hardened aluminum profiles, with surface hardening or anodizing to improve wear resistance and structural stability. For special applications, lubrication devices, chip scrapers, or dust covers can be added to extend system life and adapt to complex processing environments.

[0106] In other alternative embodiments, the guide mechanism 40 can also adopt a double-rail, double-slider structure to improve the overall torsional resistance; the displacement mechanism 30 can also be configured with a multi-axis linkage structure according to the characteristics of the workpiece to achieve spatial adjustment in a two-dimensional or three-dimensional range. The control system can monitor the movement status in real time through encoders, displacement sensors, etc., to achieve precise control.

[0107] In this embodiment, by employing technical means including a moving end and a guiding mechanism 40, the housing 230 of the grinding device can obtain additional translational adjustment capability in addition to the vertical contact action, and provides high-precision guidance through the sliding cooperation formed by the linear guide rail and the slider. Therefore, it effectively solves the problems of insufficient adjustment freedom, poor position offset accuracy and low dynamic response stability of the grinding device in the prior art, thereby achieving the technical effects of enhanced device positioning flexibility, improved grinding trajectory control accuracy and enhanced adaptability to multiple working conditions.

[0108] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
