[0002] Grooved shafts are key components in industrial equipment such as textile machinery, and their surface precision and smoothness directly affect the operating performance of the equipment. Grooved shafts are usually made of metal alloys, requiring extremely high machining precision.

[0003] Existing equipment for machining grooved shafts is generally traditional and often fails to meet the demands of high-precision grinding. It suffers from low processing efficiency, difficulty in precision control, and a tendency to generate dead angles, making it unsuitable for fine machining of grooved shafts and thus limiting its applications. Therefore, there is an urgent need to provide a high-precision grinding machine for grooved shafts to overcome these shortcomings in current practical applications. Summary of the Invention

[0050] And a fine-tuning actuator, connected between the linkage and the crank-rocker reciprocating drive module;

[0051] The data processing terminal generates a compensation command based on the deviation value, which drives the fine-tuning actuator to adjust the travel limit position or feed speed of the reciprocating sliding seat to achieve closed-loop feedback control.

[0052] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0053] This invention utilizes the combination of a hydraulic elastic thrust chamber and an elastic traction spring in the adaptive radial grinding unit. By using hydraulic oil to push the radial telescopic push rod, the arc-shaped grinding pad flexibly fits the surface of the grooved shaft. The dual mechanism of hydraulic thrust and elastic buffer can adapt to the micro-undulations and groove shape of the grooved shaft surface, ensuring constant and uniform grinding pressure. Compared with traditional rigid grinding, it effectively avoids overcutting and vibration marks, significantly improves the dimensional accuracy and surface finish of the grooved shaft, and meets the requirements of high-precision fit.

[0054] The drive assembly drives the crank rocker reciprocating drive module to work. Utilizing the transmission cooperation of the eccentric drive wheel, swing connecting rod and sector gear, it drives the reciprocating sliding seat and the adaptive radial grinding unit to perform high-frequency and stable left and right reciprocating motion along the axial direction of the groove cylinder shaft. At the same time, the hollow rotary grinding shaft rotates at high speed. The composite motion trajectory of rotation and axial reciprocating motion ensures that the arc-shaped grinding pad can fully cover the spiral groove, side wall and bottom of the groove cylinder shaft, completely eliminating processing dead angles and ensuring the grinding uniformity and consistency of the entire processing area.

[0055] An innovative air-liquid synergistic cleaning device linked to reciprocating motion is set up; the mechanical displacement generated by the reciprocating sliding seat during reciprocating movement directly drives the telescopic bellows to extend and retract, forcing air into the cleaning ring through the first duct and spraying it out through the nozzle; this process does not require an additional power source, and can blow away the fine grinding debris and dust adhering to the surface of the groove cylinder shaft during or immediately after grinding, effectively preventing surface scratches caused by grinding debris embedding, and further ensuring the surface integrity of the finished product;

[0056] The bidirectional self-locking clamping mechanism uses a bidirectional threaded rod to drive two sets of clamping plates to move in opposite directions. It not only provides a strong clamping force to resist grinding vibration and prevent workpiece displacement, but also achieves self-centering function through the thread design with opposite directions of rotation, adapting to grooved shafts of different diameters. Combined with the design of the feed hole and support roller, it ensures smooth feeding of long shaft workpieces and ensures rigidity and stability during the processing.

[0057] This invention integrates clamping and positioning, high-precision flexible grinding, axial reciprocating feed, and online pneumatic cleaning into a single box structure, which is uniformly coordinated and controlled by a single drive system. This not only simplifies the equipment structure and reduces energy consumption, but also significantly improves the processing efficiency and yield of grooved shafts, solving the problems of dispersed processes and difficulty in controlling precision in the prior art.

[0070] The present invention will be further explained below with reference to specific embodiments.

[0071] Please see Figures 1-7 The present invention provides a high-precision grinding equipment for grooved shafts, comprising:

[0072] Box 1, with material passage holes 8 on both sides;

[0073] A two-way self-locking clamping mechanism is used to fix the grooved cylinder shaft. Two sets of the two-way self-locking clamping mechanism are provided and installed on the housing 1.

[0074] The reciprocating sliding seat 16 is slidably installed inside the housing 1;

[0075] A crank-rocker reciprocating drive module is installed inside the housing 1 to drive the reciprocating sliding seat 16 to reciprocate within the housing 1.

[0076] An adaptive radial grinding unit, rotatably mounted on the reciprocating sliding seat 16, is used for high-precision grinding of the grooved shaft; and

[0077] The drive assembly is disposed inside the housing 1 and is connected to the crank-rocker reciprocating drive module and the adaptive radial grinding unit respectively, for driving the crank-rocker reciprocating drive module to work and driving the adaptive radial grinding unit to rotate.

[0078] In an embodiment of the present invention, during processing, the grooved shaft is inserted into the housing 1 through the feed hole 8, and the area to be ground is moved into the adaptive radial grinding unit. After the grooved shaft is adjusted, it is fixed by a bidirectional self-locking clamping mechanism. The drive assembly drives the reciprocating sliding seat 16 to move back and forth in the housing 1 by driving the crank rocker to reciprocate. This drives the adaptive radial grinding unit to move back and forth in the housing 1. In conjunction with the drive assembly driving the adaptive radial grinding unit to rotate, high-precision grinding of the grooved shaft is achieved. The adaptive radial grinding unit can achieve comprehensive grinding of the area to be processed on the grooved shaft by rotating and reciprocating within the housing 1, avoiding processing dead corners and improving processing quality. Compared with the prior art, the present invention, through the coordinated arrangement of the bidirectional self-locking clamping mechanism, the crank rocker reciprocating drive module, the reciprocating sliding seat 16 and the adaptive radial grinding unit, avoids the problems that existing grooved shaft processing equipment is generally more traditional and mostly unable to meet the requirements of high-precision grinding, with problems such as low processing efficiency, difficulty in precision control, and easy generation of dead corners. It is not suitable for fine processing of grooved shafts and has certain limitations.

[0079] For a more specific example, please refer to Figures 1-6 The adaptive radial grinding unit includes:

[0080] Two sets of fluid guide rings 22 are fixedly installed on the reciprocating sliding seat 16, and a second conduit 23 is provided on the fluid guide ring 22;

[0081] A hollow rotary grinding shaft 19 is rotatably mounted inside the fluid guide ring 22. A flow groove 29 is provided inside the hollow rotary grinding shaft 19, and an annular flow groove communicating with the flow groove 29 is provided inside the fluid guide ring 22.

[0082] Multiple elastic pushing cavities 30 are formed on the hollow rotary grinding shaft 19, and the elastic pushing cavities 30 are connected to the flow groove 29;

[0083] The radial telescopic push rod 27 is slidably installed inside the hollow rotary grinding shaft 19; and

[0084] The arc-shaped grinding tile 28 is fixedly installed on the radial telescopic top rod 27;

[0085] Among them, a spring 31 is sleeved on the radial telescopic top rod 27. One end of the spring 31 is fixedly connected to the inner wall of the hollow rotary grinding shaft 19, and the other end is fixedly connected to the arc-shaped grinding tile 28, which is used to elastically reset the arc-shaped grinding tile 28.

[0086] The adaptive radial grinding unit also includes a first gear 20 and a second gear 21;

[0087] The first gear 20 is fixedly mounted on the hollow rotary grinding shaft 19;

[0088] The second gear 21 is rotatably mounted inside the housing 1 via the second rotating shaft 25 and meshes with the first gear 20;

[0089] The second rotating shaft 25 is connected to the drive assembly for transmission.

[0090] In this embodiment, after the grooved cylinder shaft extends into the hollow rotary grinding shaft 19, hydraulic oil can be introduced into the fluid guide ring 22 through the second conduit 23. The hydraulic oil will be introduced into the flow groove 29 through the fluid guide ring 22. The flow groove 29 will divert the hydraulic oil into the elastic push cavity 30, thereby pushing the radial telescopic push rod 27 to move, so that the arc-shaped grinding tile 28 can contact the surface of the grooved cylinder shaft. The drive component can drive the second gear 21 to rotate by driving the second rotating shaft 25 to rotate, thereby driving the hollow rotary grinding shaft 19 to rotate. The hollow rotary grinding shaft 19 can perform high-precision grinding by driving the arc-shaped grinding tile 28 to rotate around the grooved cylinder shaft. The arc-shaped grinding tile 28 can be reset by the spring 31.

[0091] For a more specific example, please refer to Figures 1-7 The crank-rocker reciprocating drive module includes:

[0092] The rack 15 is fixedly installed on the reciprocating sliding seat 16;

[0093] The sector gear 12 is rotatably mounted on the housing 1 via the first rotating shaft 13 and meshes with the rack 15;

[0094] The swing linkage 11 is fixedly mounted on the sector gear 12; and

[0095] An eccentric drive wheel 9 is rotatably mounted on the housing 1 via a fourth rotating shaft 32. A drive column 10 is fixedly mounted on the edge of the eccentric drive wheel 9, and the drive column 10 is slidably engaged with the swing link 11.

[0096] The fourth rotating shaft 32 is connected to the drive assembly for transmission.

[0097] In this embodiment, the drive assembly drives the eccentric drive wheel 9 to rotate, which in turn drives the drive column 10 to rotate around the fourth shaft 32. The drive column 10 drives the swing link 11 to swing back and forth around the first shaft 13, which in turn drives the sector gear 12 to swing back and forth around the first shaft 13. Through the meshing of the sector gear 12 and the rack 15, the reciprocating sliding seat 16 can be driven to move back and forth left and right within the housing 1, thereby driving the adaptive radial grinding unit to move back and forth along the line connecting the two sets of feed holes 8, which facilitates repeated grinding of the grooved shaft and improves the grinding effect. The swing link 12 has an inverted U-shaped structure.

[0098] For a more specific example, please refer to Figures 1-7 The driving component includes:

[0099] The third rotating shaft 26 is rotatably mounted on the housing 1;

[0100] Motor 3 is mounted on the housing 1 and is used to drive the third rotating shaft 26 to rotate.

[0101] Gear set 2, connected between the third rotating shaft 26 and the fourth rotating shaft 32; and

[0102] Linkage component 24 is connected between the third rotating shaft 26 and the adaptive radial grinding unit.

[0103] In this embodiment, the motor 3 drives the third rotating shaft 26 to rotate, and in conjunction with the transmission action of the gear set 2 and the linkage 24, it enables the second rotating shaft 25 and the fourth rotating shaft 32 to rotate, thereby driving the adaptive radial grinding unit to rotate and driving the crank rocker reciprocating drive module to work; wherein the linkage 24 adopts a combination structure of pulley and transmission belt, and the gear set 2 consists of two sets of meshing bevel gears.

[0104] For a more specific example, please refer to Figures 1-7 The bidirectional self-locking clamping mechanism includes:

[0105] Both sets of clamping plates 6 are slidably mounted on the housing 1;

[0106] Threaded rod 5 is rotatably mounted on the housing 1, and the threaded rod 5 is threadedly connected to both sets of clamping plates 6; and

[0107] The power module 4 is used to drive the threaded rod 5 to rotate.

[0108] In this embodiment, the power module 4 is a prior art technology that can drive the threaded rod 5 to rotate. The threaded rod 5 has two sets of threads with opposite directions. By driving the threaded rod 5 to rotate, the power module 4 can drive the two sets of clamping plates 6 to move in opposite directions, which is convenient for fixing the grooved shaft. One of the clamping plates 6 of the bidirectional self-locking clamping mechanism can be equipped with a support roller 7, which is convenient for pushing the grooved shaft to move within the housing 1.

[0109] For a more specific example, please refer to Figures 1-7 It also includes a gas-liquid synergistic cleaning device, which is installed inside the housing 1. The gas-liquid synergistic cleaning device includes:

[0110] A cleaning ring 17 is fixedly installed inside the housing 1, and multiple nozzles are provided inside the cleaning ring 17;

[0111] A telescopic bellows box 14 is fixedly installed on the housing 1, and the telescopic end of the telescopic bellows box 14 is fixedly connected to the reciprocating sliding seat 16; and

[0112] The first conduit 18 is connected between the cleaning ring 17 and the telescopic bellows 14.

[0113] In this embodiment, the reciprocating sliding seat 16 can repeatedly stretch or compress the telescopic bellows 14 by moving left and right, so that gas is introduced into the cleaning ring 17 through the first conduit 18 and sprayed out through the nozzle inside the cleaning ring 17. When the ground grooved shaft passes through the cleaning ring 17, it can remove impurities such as grinding debris and dust from the surface of the grooved shaft, thereby improving the processing quality. The nozzle inside the cleaning ring 17 is equipped with a filter screen to prevent impurities from being sucked in.

[0114] In a more specific example, an intelligent fluid control system is also included, which comprises:

[0115] A pressure sensor is embedded at the inlet of the flow channel 29 to monitor the pressure value of the cooling medium in real time.

[0116] A flow regulating valve is installed in series on the second conduit 23;

[0117] The control unit is electrically connected to the pressure sensor and the flow regulating valve, respectively.

[0118] The control unit is configured to: increase the opening of the flow regulating valve to increase the medium flow rate when the detected value of the pressure sensor is lower than a preset threshold; and decrease the opening when the detected value is higher than the preset threshold to prevent the arc grinding tile 28 from overcutting due to excessive hydraulic pressure.

[0119] Specifically, a high-sensitivity pressure sensor is embedded at the inlet of the inner circulation channel 29 of the hollow rotary grinding shaft 19, which collects the medium pressure data in the channel in real time. An electric flow regulating valve is connected in series on the second infusion pipe 23 that connects to the fluid guide ring 22.

[0120] The system also includes an independent control unit (such as a PLC or embedded microcontroller), whose input is connected to a pressure sensor and whose output is connected to a flow regulating valve.

[0121] Working principle: During grinding, when the grinding load increases, causing the back pressure inside the flow channel to rise (possibly due to blockage or poor heat dissipation), the pressure sensor detects that the value exceeds the preset upper limit. The control unit immediately instructs the flow regulating valve to reduce its opening to prevent the high-pressure fluid from excessively pushing out the arc-shaped grinding tile 28, causing over-cutting. Conversely, when the pressure is detected to be below the lower limit (possibly due to leakage or insufficient flow), the control unit increases the valve opening to ensure continuous and effective cooling and lubrication. This system achieves adaptive adjustment of the cooling strategy.

[0122] In a more specific example, an online size monitoring and compensation module is also included, which comprises:

[0123] Two sets of laser displacement sensors are symmetrically installed inside the housing 1 and located between the bidirectional self-locking clamping mechanism and the adaptive radial grinding unit, for non-contact measurement of the real-time outer diameter of the grooved cylinder shaft;

[0124] The data processing terminal is communicatively connected to the laser displacement sensor and is used to compare the real-time outer diameter data with the preset target size and calculate the deviation value.

[0125] And a fine-tuning actuator, connected between the linkage 24 and the crank-rocker reciprocating drive module;

[0126] The data processing terminal generates a compensation command based on the deviation value, which drives the fine-tuning actuator to adjust the stroke limit position or feed speed of the reciprocating sliding seat 16 to achieve closed-loop feedback control.

[0127] The sensor's beam shines perpendicularly onto the surface of the grooved shaft to be processed, collecting outer diameter data in real time and transmitting it to the data processing terminal (industrial control computer). The data processing terminal has a pre-stored target size tolerance range, which compares the real-time measured value with the target value and calculates the real-time deviation value.

[0128] If the deviation exceeds the allowable range, the data processing terminal generates a compensation command and sends it to the fine-tuning actuator (such as a precision electric actuator or servo motor) connected between the power transmission system and the crank-rocker reciprocating drive module.

[0129] The fine-tuning actuator adjusts the travel limit position of the reciprocating sliding seat 16 (changing the grinding depth) or adjusts the feed rate according to instructions. For example, when the measured diameter is greater than the target value, the system automatically increases the grinding feed; when it approaches the target size, it automatically switches to micro-feed mode. This process is fully automated, requiring no manual intervention, and realizes closed-loop feedback control of the machining process, ensuring high precision and consistency of the final product.

[0130] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
