[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] This embodiment provides a cylinder grinding device, such as Figures 1-6 As shown, the assembly includes a drive motor 1, a motion conversion component 2, a grinding component 3, a guide component 4, and a control component. The drive motor 1 is connected to the motion conversion component 2; the motion conversion component 2 is connected to the grinding component 3; the grinding component 3 includes a cylinder 31 and a lead screw 32, with the lead screw 32 disposed inside the cylinder 31; the guide component 4 is connected to the grinding component 3; and the control component is connected to the drive motor 1. The control component is a PLC control system.

[0024] The drive motor 1 and motion conversion component 2 transmit power through a direct mechanical connection. The motion conversion component 2 is fixedly connected to the cylinder 31 and lead screw 32 of the grinding component 3, thereby transmitting the converted motion to the grinding component 3. The guide component 4 is connected to the lead screw 32 of the grinding component 3 through a sliding mechanism to ensure the stability of the motion direction. The control component is connected to the drive motor 1 through electrical circuitry to adjust and monitor operating parameters. More specifically, these components form a close linkage: the drive motor 1 provides the power source for rotational motion, the motion conversion component 2 is responsible for converting the motion form, the grinding component 3 performs the actual grinding operation, the guide component 4 provides path guidance, and the control component coordinates the overall action, thus constructing a complete grinding system. The drive motor 1 provides adjustable rotational power to propel the device. The motion conversion component 2 converts the rotational motion of the drive motor 1 into the linear motion required by the grinding component 3, ensuring efficient and precise power transmission. The grinding component 3 grinds the inner wall of the electric cylinder through the interaction of the cylinder 31 and the lead screw 32, directly improving surface quality. The guide component 4 guides and restricts the movement trajectory of the grinding component 3, preventing deviation and improving straightness. The control component adjusts the speed and position parameters of the drive motor 1, achieving automated control and adaptive adjustment. Furthermore, each component performs its specific function, working together to ensure the efficiency and precision of the grinding process.

[0025] Drive motor 1 starts under the command of control component and outputs rotational motion to motion conversion component 2. Motion conversion component 2 converts this rotational motion into linear motion and transmits it to grinding component 3, so that lead screw 32 reciprocates inside cylinder 31, thereby achieving grinding of the inner wall. At the same time, guide component 4 guides the movement of grinding component 3, maintaining its linearity and stability. Control component monitors the status of drive motor 1 in real time and adjusts parameters such as speed and running time to adapt to the grinding requirements of different cylinders.

[0026] This embodiment provides an adjustable power source through a drive motor 1, and a motion conversion component 2 efficiently converts rotary motion into linear motion, enabling the grinding component 3 to perform precision grinding on the inner wall of the cylinder. A guiding component 4 ensures the linearity and stability of the grinding motion, reducing errors, and a control component allows for flexible parameter settings to adapt to cylinders of different lengths and strokes. More specifically, this integrated design solves the problems of low grinding accuracy and difficulty in guaranteeing surface quality in the prior art. Through automated control, it achieves precision grinding with multi-stroke motion, thereby improving the transmission accuracy and service life of the electric cylinder and meeting the needs of high-efficiency processing.

[0027] In a specific embodiment, the motion conversion component 2 includes a coupling 21, a main shaft 22, and a clamping unit 23; the two ends of the coupling 21 are respectively connected to the drive motor 1 and the main shaft 22; the main shaft 22 is connected to the clamping unit 23, and the clamping unit 23 is used to clamp the cylinder 31.

[0028] The two ends of the coupling 21 are directly mechanically connected to the output shaft of the drive motor 1 and one end of the main shaft 22, respectively, to ensure effective power transmission. The other end of the main shaft 22 is fixedly connected to the clamping unit 23, typically using screws or similar fasteners for rigid connection. The clamping unit 23 is in close contact with and fixed to the outer wall of the cylinder 31 through its internal clamping mechanism, thus forming a continuous transmission chain from the drive motor 1 to the cylinder 31. More specifically, the coupling 21 connects the drive motor 1 and the main shaft 22, transmits rotational power, and compensates for any possible minor deviations to ensure smooth movement. The main shaft 22 acts as an intermediate transmission shaft, reliably transmitting the rotational motion from the coupling 21 to the clamping unit 23, maintaining the continuity and accuracy of power transmission. The clamping unit 23 firmly clamps the cylinder 31, preventing it from sliding or shifting during movement, ensuring that the cylinder 31 can rotate with the main shaft 22, thus providing a stable foundation for subsequent grinding operations.

[0029] The coupling 21 first receives the rotational motion of the drive motor 1 and transmits it to the main shaft 22. The main shaft 22 then transmits this rotational motion to the clamping unit 23, which in turn drives the cylinder 31 it clamps to rotate, thus achieving continuity in the entire motion conversion process. This coordinated operation ensures that the rotational motion is transmitted to the cylinder 31 accurately and without loss, providing a power basis for the linear motion of the grinding assembly 3, improving the efficiency and stability of motion transmission, reducing vibration and errors, thereby laying the foundation for the precision grinding of the cylinder's inner wall and further enhancing the reliability and processing quality of the entire device.

[0030] In a specific embodiment, the motion conversion component 2 further includes a motor mounting base 24, a spindle mounting base 25, and an end cover; the drive motor 1 is fixed by the motor mounting base 24, the spindle 22 is supported by the spindle mounting base 25, and the end cover is connected between the drive motor 1 and the spindle mounting base 25 to ensure their coaxiality.

[0031] The motor mounting base 24 is fixedly connected to the housing of the drive motor 1 by bolts, stably mounting it on the device base. The spindle mounting base 25 is connected to the spindle 22 through an internal support structure such as bearings, providing rotational support. The end cap is located between the output end of the drive motor 1 and the input end of the spindle mounting base 25, and precision machining ensures a tight fit between the two. The main function of the motor mounting base 24 is to provide a solid fixed foundation for the drive motor 1, preventing it from shaking or shifting during operation and ensuring the stability of power output. The function of the spindle mounting base 25 is to support the spindle 22, keeping it stable during rotation and reducing vibration, and bearing the load from the transmission process. The function of the end cap is to connect the drive motor 1 and the spindle mounting base 25, and its structural design ensures that the rotation axes of the two are aligned, avoiding eccentricity.

[0032] The motor mounting base 24 first securely fixes the drive motor 1, while the spindle mounting base 25 supports the spindle 22 and allows it to rotate efficiently. The end cap is precisely installed to coordinate the relative positions between the drive motor 1 and the spindle mounting base 25, ensuring that the axis is consistent during the transmission of rotational motion from the drive motor 1 to the spindle 22. This coordinated operation reduces energy loss and mechanical vibration during motion conversion, improves the smoothness of operation and transmission efficiency of the entire device, and reduces the risk of component wear.

[0033] In a specific embodiment, the clamping unit 23 is a three-jaw chuck, which is connected to the main shaft 22 by screws and is used to clamp one end of the cylinder 31.

[0034] The three-jaw chuck is rigidly connected to the spindle 22 via screws, ensuring that the two rotate synchronously without relative displacement during rotation. The three-jaw chuck uses its three radially movable jaws to evenly clamp one end of the cylinder 31. This clamping method can automatically center and adapt to cylinders of different diameters. More specifically, the screw connection provides a stable fixing point, while the synchronous adjustment of the jaws ensures a uniform distribution of clamping force, preventing the cylinder from sliding or shifting under high-speed rotation, improving the efficiency and reliability of power transmission, and reducing vibration and errors during the grinding process. At the same time, due to the versatility of the three-jaw chuck, the device can quickly adapt to cylinders of various specifications, enhancing the flexibility of the equipment.

[0035] In a specific embodiment, the guide component 4 includes a guide rail unit 41 and a sliding unit 42. The sliding unit 42 is disposed on the guide rail unit 41 and connected to the grinding component 3.

[0036] The sliding unit 42 is directly mounted on the track of the guide rail unit 41. Through sliding surface contact, it can move smoothly along the preset path of the guide rail unit 41. At the same time, the sliding unit 42 is fixedly connected to the lead screw part of the grinding assembly 3 to transmit linear motion. The function of the guide rail unit 41 is to provide a high-precision linear guide reference, limit the direction of movement and absorb radial force, and ensure that the movement trajectory of the entire grinding assembly 3 is accurate. The function of the sliding unit 42 is to bear part of the load of the grinding assembly 3 and slide on the guide rail unit 41, so as to efficiently transmit the linear motion converted from rotation to the grinding point.

[0037] When the drive motor 1 drives the grinding assembly 3 through the motion conversion component 2, the sliding unit 42 is pushed and makes linear reciprocating motion on the guide rail unit 41, which drives the lead screw 32 to move inside the cylinder 31. The guide rail unit 41 guides and constrains the movement direction of the sliding unit 42 through its rigid structure, preventing any lateral deviation or vibration. This cooperative work ensures that the grinding pressure is applied evenly to the inner wall of the cylinder, improves the straightness of the grinding, reduces processing errors and equipment wear. At the same time, due to the stable guidance, the device can adapt to cylinders of different lengths and realize multi-lead grinding, thereby improving the overall performance of the electric cylinder.

[0038] In a specific embodiment, the guide rail unit 41 includes a guide plate and a guide rail, the guide plate being connected to the base plate 7; the guide rail being disposed on the guide plate; the sliding unit 42 is a slider, the slider being disposed on the guide rail.

[0039] The guide plate is securely connected to the base plate 7 by bolts or similar fasteners, providing a stable mounting base for the entire guide assembly. The guide rail is precisely fixed to the upper surface of the guide plate, usually by embedding it into the slots on the guide plate or by direct mechanical fixing to ensure accurate positioning. The sliding unit 42 is directly mounted on the guide rail as a slider, achieving smooth linear movement through sliding surface contact. More specifically, the guide plate's function is to distribute the load and maintain the flatness of the guide rail, preventing deformation caused by external forces. The guide rail's function is to provide a high-precision linear motion trajectory, guiding the slider to move in a predetermined direction. The slider's function is to bear part of the weight of the grinding assembly 3 and transmit linear motion, ensuring the smoothness and repeatability of the motion process. The effect of this structure is to significantly enhance the guiding stability and rigidity of the grinding device, reduce vibration and offset during the motion process, thereby ensuring the straightness and surface uniformity of the cylinder inner wall grinding. At the same time, due to the secure connection between the guide plate and the base plate 7, the device can adapt to guide rail configurations of different lengths, achieving multi-lead precision motion and improving overall processing efficiency.

[0040] In a specific embodiment, the cylinder grinding device further includes a support assembly 6, such as... Figure 6 As shown, the support assembly 6 includes a bearing unit, which is disposed inside the cylinder 31 and is used to support the lead screw 32.

[0041] In the cylinder grinding device, the bearing unit of the support assembly 6 is integrated into the internal cavity of the cylinder 31. The lead screw 32 passes through the bearing unit and obtains radial and axial support through its internal structure such as rolling elements or sleeves. This arrangement allows the bearing unit to directly bear the load generated by the lead screw 32 during reciprocating motion. The bearing unit is tightly fitted to the inner wall of the cylinder 31 through its fixing method, ensuring that the lead screw 32 remains stably aligned under high speed or high load conditions, preventing skew or shaking. Its function is to provide continuous mechanical support, disperse motion stress, and maintain the relative positional accuracy between the lead screw 32 and the cylinder 31, thereby improving the smoothness and consistency of the grinding process, reducing surface defects caused by vibration, and extending the service life of the lead screw 32 and the cylinder 31. At the same time, due to the effective support, the device can adapt to grinding tasks with longer strokes, ensuring that the processing quality of the inner wall of the electric cylinder reaches a higher standard.

[0042] In a specific embodiment, the support component 6 further includes an expansion sleeve, which is used to fix the bearing unit.

[0043] The expansion sleeve is fitted in the annular gap between the bearing unit and the inner wall of the cylinder 31 or the relevant support seat. When axial force is applied by bolts or similar fasteners, the expansion sleeve undergoes radial elastic deformation, its outer wall tightly fitting the inner wall of the cylinder 31, while its inner wall firmly grips the outer ring of the bearing unit, thus forming a robust locking mechanism. Its function is to eliminate the fit clearance between the bearing unit and the support structure, providing a strong clamping force for a keyless connection, effectively preventing any slight rotation or axial movement of the bearing unit during operation. More specifically, this fixing method can accommodate certain dimensional tolerances, ensuring accurate positioning and alignment of the bearing unit. It enhances the rigidity and stability of the entire support assembly 6, allowing the lead screw 32 to obtain more precise radial support during high-speed reciprocating motion, significantly reducing vibration and noise, while avoiding wear and precision loss caused by bearing loosening, thereby ensuring the smoothness and consistency of the cylinder inner wall grinding process.

[0044] In a specific embodiment, the lead screw 32 includes a fixed section and an output section. The fixed section is connected to the sliding unit 42 by a locking nut, and the output section passes through the support assembly 6.

[0045] The fixed section of the lead screw 32 is rigidly connected to the sliding unit 42 through a locking nut, ensuring that the two move synchronously without relative displacement during movement. The output section is designed to extend and pass through the internal structure of the support assembly 6, allowing the output section to slide smoothly within the bearing unit and other support components during reciprocating motion of the lead screw 32. This segmented design allows the fixed section to bear the power transmission and fixing functions, while the output section is responsible for performing linear motion and receiving external support. Its effect is to significantly improve the stability and guiding accuracy of the lead screw 32's movement, reduce grinding errors caused by vibration or offset, and at the same time, the locking nut connection method enhances the reliability of the overall structure, prevents loosening, and ensures efficient power transmission.

[0046] In a specific embodiment, the bearing unit includes a bearing housing 61, a bearing 62, and a limiting plate 63. The bearing housing 61 is connected to the guide assembly 4. The bearing 62 is disposed inside the bearing housing 61. The limiting plate 63 is used to fix the bearing 62. A self-locking block 64 is provided on the limiting plate 63.

[0047] In this embodiment, the bearing housing 61 is fixed to the guide rail portion of the guide assembly 4 via a mechanical connection. The bearing housing 61 has a precisely machined cavity to accommodate the bearing 62. The outer ring of the bearing 62 is tightly fitted into the cavity of the bearing housing 61, while its inner ring supports the lead screw 32. The limiting plate 63 is fastened to the end face of the bearing housing 61 with screws. Its structure covers the outside of the bearing 62, forming a closed or semi-closed space with the bearing housing 61 to restrict the axial movement of the bearing 62. More specifically, the bearing housing 61 serves as a supporting frame, providing a rigid mounting base and precise positioning for the entire bearing unit; the bearing 62 supports the rotating or reciprocating lead screw 32, reducing frictional resistance during its movement and bearing radial loads; the limiting plate 63 constrains and fixes the bearing 62 axially, preventing it from shifting during operation. These components work together in close mechanical coordination. The bearing housing 61 provides a stable foundation, the bearing 62 ensures smooth and low-friction movement of the lead screw 32, and the limiting plate 63 locks the bearing 62 in place from the end face. Together, they form a high-precision support structure. The result is a significant enhancement of the stability and rotational accuracy of the lead screw 32 during high-speed reciprocating motion, effectively suppressing vibration and axial movement, ensuring the precise and reliable running trajectory of the grinding assembly 3, thereby directly improving the dimensional accuracy and surface smoothness of the inner wall grinding of the cylinder 31, and ultimately guaranteeing the transmission performance and service life of the electric cylinder.

[0048] The cylinder grinding device also includes a display component 8, which mainly comprises a teach pendant 81 and a button mounting box 82. Together, they form a human-machine interface for setting grinding parameters, inputting control commands, and displaying the device's operating status. It also includes a safety protection component 9, specifically a safety guard, which is installed outside the device's moving parts such as the spindle 22 and the three-jaw chuck to isolate the moving areas, prevent accidental contact by operators, and block the splashing of grinding debris. Furthermore, the device includes a power component 5, specifically a power distribution cabinet, which integrates electrical components and provides power distribution and control for servo motors, etc.

[0049] The operation of the cylinder grinding device provided in this embodiment begins with the start of the drive motor 1, whose rotational output is transmitted to the main shaft 22 via the coupling 21. The rotational motion of the main shaft 22 is stably supported by the main shaft mounting seat 25 and synchronously rotates the cylinder 31 clamped by the clamping unit 23, i.e., the three-jaw chuck. More specifically, the planetary roller screw placed inside the cylinder 31 then enters the working state. The fixed section of the screw 32 is firmly connected to the sliding unit 42, i.e., the slider, through the locking nut, while the output section passes through the support assembly 6, which consists of a bearing unit and a shrink sleeve. When the cylinder 31 rotates, the screw 32 is converted into precise linear reciprocating motion under the action of the threaded pair. At this time, the guide rail set on the guide plate and the slider mounted on it provide high-precision guidance for the linear motion of the screw 32, effectively suppressing radial offset. Throughout the process, the support assembly 6 plays a key role. The bearing 62 in the bearing seat 61 provides rotational support for the screw 32, while the limiting plate 63 ensures the axial positioning of the bearing 62. The control components continuously monitor and adjust the operating parameters of the drive motor 1, thereby achieving precise control over the reciprocating stroke, speed, and position of the lead screw 32. Ultimately, this continuous electromechanical linkage process enables the lead screw 32 to perform precise reciprocating grinding motion within the cylinder 31, efficiently and uniformly machining the inner wall of the cylinder, thereby improving product precision and surface quality.
