[0016] The present invention also claims protection for a method of using an internal meshing numerically controlled high-power honing machine, including an internal meshing numerically controlled high-power honing machine, where the honing machine is the honing machine as claimed in the claims, and the method of using the honing machine includes the following steps:

[0017] S1. During machining, the workpiece is connected to the workpiece spindle through a fixture. The Z-axis slide moves along the Z direction to the position of the U-axis automatic tool setting device. The U-axis automatic tool setting device drives the inductive tool setting probe to move near the outer circle of the workpiece through the servo motor Ⅴ. The workpiece spindle rotates to complete the workpiece phase measurement.

[0018] S2. After the A-axis shaft intersection angle adjustment shaft is relaxed, the servo motor Ⅳ drives the B-axis honing wheel spindle to rotate the A-axis shaft intersection angle adjustment shaft to the required angle, and the A-axis shaft intersection angle adjustment shaft is locked. The B-axis honing wheel spindle and the A-axis shaft intersection angle adjustment shaft move to a safe position along with the X-axis honing head slide.

[0019] S3. The workpiece spindle and the B-axis honing wheel spindle rotate at high speed according to the set speed. The workpiece follows the Z-axis slide and the tailstock follows the W-axis tailstock slide to move continuously along the Z direction. The B-axis honing wheel spindle and the A-axis axis intersection angle adjustment axis move continuously along the X direction with the X-axis honing head slide. The workpiece machining or honing wheel dressing is realized through the interpolation linkage of the rotation of the workpiece spindle, the rotation of the B-axis honing wheel spindle, the movement of the workpiece spindle along the Z direction, and the movement of the tailstock along the Z direction.

[0021] Furthermore, it also includes the step of adjusting the tailstock axis to be at the same height as the honing wheel axis before machining:

[0022] S01. Prepare a wrench tool and loosen the bolts for eccentrically installing the tailstock on the tailstock housing.

[0023] S02. According to the relative position of the tailstock axis and the honing wheel axis, determine the direction in which the tailstock needs to be adjusted, and prepare to rotate the tailstock upward or downward.

[0024] S03. Use the tool to rotate the tailstock. Utilize the characteristics of the eccentric structure to move the tailstock axis. During the rotation of the tailstock, observe the change of the tailstock axis for timely adjustment.

[0025] S04. During the adjustment process, use a measuring tool, a laser rangefinder, to measure the height difference between the tailstock axis and the honing wheel axis to ensure that the two are at the same height. When the desired height is reached, stop rotating the tailstock.

[0026] S05. After the adjustment is completed, use bolts to fix the tailstock on the tailstock housing to prevent the tailstock from moving during use.

[0029] 2. The B-axis honing wheel spindle of the present invention is designed with a hollow structure to realize the installation of the honing wheel tool. Through the drive control and positioning of the built-in spindle motor, and the high-precision and high-speed bearings for load-bearing centering, it ensures the high dynamic response and position control of the internal meshing generating motion.

[0030] 3.

Detailed Description of the Invention

[0039] The following will combine the accompanying drawings in the embodiments of the present invention Figures 1-3 , and clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] (as Figure 1 shown) An internal meshing numerically controlled high-power honing machine, including a horizontal bed 1, one end of the bed 1 is provided with a Z-axis slide 4, and the Z-axis slide 4 carries a workpiece spindle 5 to realize the feeding movement of the workpiece in the Z direction.

[0041] It should be noted that: The horizontal bed 1 provides a stable support foundation, reduces the machining errors caused by machine tool vibration, and realizes high-precision gear machining. The design of the Z-axis slide 4 carrying the workpiece spindle 5 enables the workpiece to accurately feed in the Z direction, ensuring the tooth profile accuracy and surface quality of the gear. With the fast moving ability of the Z-axis slide 4, the workpiece can quickly be positioned to the machining position, shortening the machining preparation time and improving the machining efficiency. The combination of the continuous rotation of the workpiece spindle 5 and the feeding movement of the Z-axis slide 4 realizes the continuous machining of the gear and improves the machining efficiency. The rigid design of the horizontal bed 1 and the Z-axis slide 4 enables the machine tool to maintain stable performance during machining, reduces the machining errors caused by deformation, and also has good anti-vibration performance, can resist the vibration generated during machining, and maintains the stability of the machining process. By adjusting the position of the Z-axis slide 4 and the rotation speed of the workpiece spindle 5, it can adapt to the machining requirements of different sizes and types of gears. The modular design of the horizontal bed 1 and the Z-axis slide 4 makes the maintenance and repair of the machine tool simple and convenient, reducing the maintenance cost and time. The open structure of the machine tool enables the maintenance personnel to easily access the key components for quick maintenance and replacement.

[0042] Furthermore: The Z-axis slide 4 is provided with the primary part I of a linear motor I 2, and the bed 1 is provided with the secondary part I of the linear motor I 2. The linear motor I 2 realizes the linear feeding movement of the Z-axis slide 4 in the Z direction through a Z-direction linear guide pair I 3; or the Z-axis slide 4 is driven by a servo motor I and realizes the linear feeding movement of the Z-axis slide 4 in the Z direction through a lead screw nut screw pair I. Specifically, the position actual data of the Z-axis slide 4 is detected by a linear grating scale, and full-closed-loop precise control is carried out to realize the feed along the axial direction of the workpiece, and the Z-axis slide 4 participates in the interpolation linkage of the machining.

[0043] It should be noted that when the Z-axis slide 4 is driven by the linear motor I 2, the linear motor I 2 directly converts electrical energy into linear motion mechanical energy, without an intermediate conversion mechanism, with high transmission efficiency, low wear, simple maintenance, and can achieve high-precision and high-speed linear feed. If it is driven by a servo motor I and transmitted by a lead screw nut screw pair I, stable linear feed can be achieved through precise motor control and screw transmission, and high machining accuracy can also be ensured. The position of the Z-axis slide 4 is detected in real time by a linear grating scale, providing accurate actual position data. Combining with the full closed-loop control strategy of the numerical control system, it can ensure that the linear feed motion of the Z-axis slide 4 along the Z direction is accurate without error, fully compensating for thermal expansion errors and mechanical transmission errors, and improving machining accuracy. The Z-axis slide 4 can perform interpolation linkage with other axes (such as the X-axis, Y-axis, A-axis, etc.) to achieve precision machining of complex curved surfaces, improving meshing accuracy and transmission performance. Interpolation linkage machining enables the machine tool to complete multiple machining steps in one clamping, reducing the number of workpiece clampings and machining time, and improving machining efficiency.

[0044] Furthermore: The workpiece spindle 5 is equipped with an internal spindle motor drive, a grating, and a broaching mechanism. A workpiece fixture 23 is installed at the front end of the workpiece spindle 5, and the broaching mechanism pulls the workpiece fixture 23 to achieve automatic workpiece clamping.

[0045] It should be noted that the internal spindle motor directly drives the workpiece spindle 5, improving transmission efficiency, with precise control of rotational speed and torque, and achieving high-precision machining. The grating, as a position detection device, ensures precise position control of the spindle. The broaching mechanism can automatically pull the workpiece fixture 23 to achieve rapid clamping and unloading of the workpiece, reducing the time and error of manual operation, and improving the consistency and stability of machining. The workpiece fixture 23 can adapt to various machining requirements, shortening machining preparation time; the precise design of the broaching mechanism and the workpiece fixture 23 ensures the stability and accuracy of workpiece machining.

[0046] It also includes an adjusting shim I, which is arranged between the workpiece spindle 5 and the Z-axis slide 4. The adjusting shim I is used to adjust the height of the workpiece spindle 5 along the Y direction, and further achieve the equal height adjustment between the workpiece spindle and the axis of the honing wheel.

[0047] Among them, the setting of shim I makes the height adjustment of the workpiece spindle 5 in the Y direction simple and precise. By increasing or decreasing the number or thickness of the shims, the height of the workpiece spindle 5 can be conveniently adjusted until it is equal to the axis height of the honing wheel. The equal-height adjustment is one of the key steps to ensure machining accuracy. By adjusting the shim I to make the workpiece spindle and the honing wheel axis at the same height, the machining errors caused by unequal heights can be effectively eliminated, and the machining accuracy and surface quality of the workpiece can be improved. The height adjustment of shim I is simple and fast, without complex mechanical adjustments. Only by increasing or decreasing the shims can the height adjustment be completed, greatly reducing the downtime caused by height adjustment, and improving the utilization rate and production efficiency of the equipment. The rigid design and precise installation of shim I help to enhance the stability of the entire system, reduce the machining errors caused by vibration and deformation, and ensure the machining quality. The height adjustment function achieved by shim I helps to expand the machining range of the equipment, improve the versatility and flexibility of the equipment. Precise height adjustment helps to reduce the wear between the workpiece spindle 5 and the honing wheel, and extend the service life of the equipment.

[0048] A honing head slide 22 for the X-axis is provided in the middle of the bed body 1, and the A-axis cross-angle adjustment shaft 10 that can swing is carried on the honing head slide 22 for the X-axis to realize the feeding movement of the A-axis cross-angle adjustment shaft 10 in the X direction.

[0049] It should be noted that: the swing of the A-axis cross-angle adjustment shaft 10 can adapt to workpieces with different shapes and machining requirements, expand the machining range of the honing head, improve the versatility and utilization rate of the equipment, and improve the machining accuracy and surface quality; the combination of the slide and the A-axis cross-angle adjustment shaft ensures the stability and accuracy of the feeding movement. The honing head slide 22 for the X-axis is arranged in the middle of the bed body 1, with a compact structure, reducing space occupation, improving the overall rigidity of the system, reducing vibration and deformation during machining, and improving machining stability and accuracy. The fast moving ability of the honing head slide 22 for the X-axis enables the A-axis cross-angle adjustment shaft 10 to quickly locate to the machining position, shortening the machining preparation time, integrating with the automation system, and realizing automatic loading and unloading of workpieces and automatic control of the machining process. Through the programming of the numerical control system, the combined machining of the A-axis and the X-axis can be conveniently realized, further improving the machining efficiency and automation level.

[0050] Furthermore: The primary part II of the linear motor II 20 is provided on the honing head slide 22 for the X-axis, and the secondary part II of the linear motor II 20 is provided on the bed body 1. The linear motor II 20 realizes the feeding movement of the honing head slide 22 for the X-axis in the X direction through the linear guide pair II 19 in the X direction; or the honing head slide 22 for the X-axis is driven by a servo motor II and transmitted by a lead screw-nut screw pair II to realize the feeding movement of the honing head slide 22 for the X-axis in the X direction.

[0051] Specifically, the X-axis honing head slide 22 detects actual position data of the X-axis honing head slide 22 by a linear grating ruler, and is fully closed-loop precisely controlled to achieve radial feed along the workpiece. The X-axis honing head slide 22 participates in interpolation linkage of machining.

[0052] It should be noted that: Similarly, the linear motor II 20 drive and the servo motor II drive both have high precision and high stability, reducing transmission errors. When driven by the servo motor II, the screw nut spiral pair II transmission has self-locking properties, which can prevent displacement caused by external forces. The linear grating scale detects in real time, provides accurate actual position data, fully compensates for thermal expansion errors and mechanical transmission errors, and improves processing accuracy. The interpolation linkage of the X-axis honing head slide 22 and other axes realizes precise control of complex processing paths and improves processing flexibility and adaptability. Through full closed-loop control and interpolation linkage, the cumulative error caused by the individual movement of each axis can be reduced, and the overall processing accuracy can be improved.

[0053] Further: (combined with Figure 3 ) A main support 8 for the A-axis angle adjustment shaft 10 is provided at one end of the X-axis honing head slide 22, and an auxiliary support 21 for the A-axis angle adjustment shaft 10 is provided at the other end; the A-axis angle adjustment shaft 10 is a cradle double support structure, and the A-axis angle adjustment shaft 10 is connected to the main support 8 and the auxiliary support 21 through bearing rotation supports; the A-axis angle adjustment shaft 10 is driven by a servo motor IV9, and the servo motor IV9 is equipped with a brake device, a large speed ratio reducer, and a hydraulic locking device, and cooperates with the circular grating set at the end of the auxiliary support 21 to realize the precise rotation adjustment of the A-axis angle adjustment shaft 10.

[0054] It should be noted that the A-axis angle adjustment shaft 10 adopts a cradle double support structure, which effectively improves the rigidity and stability of the A-axis and ensures the accuracy of the A-axis angle adjustment. The servo motor IV 9 realizes the fine adjustment of the A-axis angle to meet the requirements of high-precision processing; the servo motor IV

[0055] The closed-loop control characteristics of 9 make the adjustment of the A-axis angle more accurate and stable. The circular grating provides accurate feedback signals for the CNC system to ensure the precision of the A-axis angle adjustment. The main support 8 and the auxiliary support 21 provide stable support; the brake device ensures safety; the hydraulic locking device prevents displacement or shaking. The large speed ratio reducer increases the output torque, and the shaft angle adjustment is smooth and powerful. The high transmission efficiency of the reducer reduces energy loss and improves processing efficiency. The circular grating feedback signal improves processing accuracy and surface quality.

[0056] Furthermore: it also includes an adjusting gasket II, which is arranged between the X-axis honing head slide 22 and the main support 8 and the auxiliary support 21. The adjusting gasket II is used to achieve height adjustment of the main support 8 and the auxiliary support 21 along the Y direction, thereby achieving equal height adjustment of the workpiece spindle and the honing wheel axis.

[0057] Similarly, the adjusting shim II ensures equal height adjustment, guarantees machining accuracy, is simple and convenient to adjust, and improves machining efficiency. Precise height adjustment extends the service life of the equipment, makes the equipment maintenance simple and convenient, and reduces maintenance time and costs.

[0058] The A-axis angular intersection adjustment shaft 10 is fixedly connected to the B-axis honing wheel main shaft 11. The B-axis honing wheel main shaft 11 swings along with the A-axis angular intersection adjustment shaft 10. The B-axis honing wheel main shaft 11 is of a hollow structure and installs a honing wheel cutter. The honing wheel cutter cooperates with a circular grating to realize internal meshing continuous generation rotation. Among them, the specific structure of the B-axis honing wheel main shaft 11, which is of a hollow structure, for installing the honing wheel cutter refers to a grinding tool for high-power honing teeth disclosed in the publication number CN21451799U.

[0059] It should be noted that: the swinging function of the A-axis angular intersection adjustment shaft 10 enables the B-axis honing wheel main shaft 11 to swing accordingly, realizing multi-degree-of-freedom machining adjustment. This linkage mechanism enables the honing wheel cutter to flexibly adapt to workpieces with different shapes and machining requirements, improving machining accuracy. Through the feedback of the circular grating, the numerical control system can precisely control the rotation angle and speed of the honing wheel cutter to achieve high-precision machining of internal meshing continuous generation rotation. The hollow structure of the B-axis honing wheel main shaft 11 makes the installation and maintenance of the honing wheel cutter more convenient, while reducing the weight of the main shaft and improving machining efficiency; the hollow structure can also be used for passing coolant, wires, etc., further optimizing the machining process. The honing wheel cutter cooperates with the circular grating to realize internal meshing continuous generation rotation. This machining method can continuously machine the workpiece, reducing the pause and tool change time during the machining process. The continuous generation rotation also helps to improve the surface finish and consistency of the machining, further enhancing the machining efficiency. The fixed connection design of the A-axis angular intersection adjustment shaft 10 and the B-axis honing wheel main shaft 11 ensures a rigid connection between the two, reducing vibration and deformation during the machining process. This rigid connection helps to improve machining accuracy and stability and extends the service life of the equipment. The honing wheel cutter is installed on the B-axis honing wheel main shaft 11, and the stability and rigidity of the cutter are ensured through the hollow structure and precise clamping method. The stable installation of the cutter helps to reduce errors and vibrations during the machining process and improve machining quality. The linked machining of the A-axis and the B-axis enables the equipment to adapt to workpieces with different shapes and machining requirements, improving the flexibility and adaptability of the equipment.

[0060] At the other end of the bed body 1, there is a W-axis tailstock slide 16. The W-axis tailstock slide 16 moves in the Z-direction. The W-axis tailstock slide 16 installs a tailstock adjustment seat 15 and a tailstock housing 14. The tailstock adjustment seat 15 adjusts the position of the tailstock housing 14 in the X-direction through bolts. The tailstock housing 14 is installed with an eccentrically adjustable tailstock 13 through bolts (combined Figure 2) The position of the tailstock 13 is rotated to adjust the height of the tailstock axis to be equal to that of the honing wheel axis.

[0061] It should be noted that: The design of the W-axis tailstock slide 16 enables the tailstock to perform precise feeding movement along the Z direction, and the position of the tailstock can be flexibly adjusted according to the workpiece length and processing requirements. The tailstock adjustment seat 15 is bolted to the tailstock housing 14, enabling the tailstock housing 14 to be finely adjusted along the X direction, facilitating the precise alignment of the center line of the tailstock and the workpiece, and ensuring the stability and accuracy during the processing. The tailstock housing 14 eccentrically mounts the tailstock 13 through bolts, enabling the axis height and angle of the tailstock 13 to be finely adjusted, precisely adjusting the height difference between the tailstock axis and the honing wheel axis to achieve equal height adjustment, thereby improving the processing accuracy. Through precise adjustment, the processing errors caused by unequal heights are effectively eliminated, and the processing accuracy and surface quality of the workpiece are improved. The rigid design and precise installation of the W-axis tailstock slide 16, tailstock adjustment seat 15, tailstock housing 14 and tailstock 13 contribute to enhancing the rigidity of the entire processing system, which helps to reduce the processing errors caused by vibration and deformation and improve the stability of the processing process. The tailstock adjustment operation is simple and easy to understand.

[0062] Furthermore: The W-axis tailstock slide 16 is provided with the primary part III of the linear motor III 17, and the machine body 1 is provided with the secondary part III of the linear motor III 17.

The W-axis tailstock slide 16 combines a linear grating scale to detect its position to achieve full-closed-loop precise control, and the W-axis tailstock slide 16 participates in the interpolation linkage of the processing.

[0063] Similarly: Driven by the linear motor III 17, it has the ability of fast response and can realize high-speed and high-precision feeding movement. The servo motor III drives through the ball screw pair III, has self-locking property, ensures the processing stability, has high transmission efficiency, small energy loss, and improves the overall performance of the equipment. The W-axis tailstock slide 16 can perform interpolation linkage with other axes, precisely control the feeding speed and position of each axis, reduce the cumulative error, and improve the processing accuracy. By adjusting the position and feeding speed of the W-axis tailstock slide 16, workpieces of different sizes and shapes can be processed, expanding the processing range of the equipment.

[0064] Furthermore: The tailstock 13 is provided with a telescopic mechanism, and the telescopic mechanism is used to control the extension and retraction of the tailstock center; the tailstock 13 is also provided with a buffer follow-up mechanism, and the buffer follow-up mechanism realizes the follow-up of the tailstock 13 alone and also provides buffering for the W-axis follow-up or Z-axis follow-up.

[0065] It should be noted that: the telescopic mechanism can adapt to workpieces with different lengths and processing requirements; the tailstock can adapt to workpieces with different diameters and shapes, ensuring the stability and support of the workpiece. The design of the telescopic mechanism helps to reduce the vibration and deformation of the tailstock during the processing, thereby improving the processing accuracy and stability. The precise extension and retraction of the tailstock center can ensure that the workpiece is accurately supported during the processing, reducing the processing errors caused by improper support. The buffer follow-up mechanism can independently realize the follow-up function of the tailstock, ensuring the continuous support of the workpiece during the processing; the follow-up function helps to reduce the pauses and tool change times during the processing, improving the processing efficiency; the buffer follow-up mechanism provides a buffering effect during the tailstock follow-up process, reducing the damage and errors caused by impact and vibration, extending the equipment life and improving the processing quality. Through the adjustment of the buffer follow-up mechanism, the smoothness and stability of the tailstock during the follow-up process can be ensured, reducing the processing errors caused by improper movement of the tailstock. The buffer follow-up mechanism not only supports the independent follow-up of the tailstock, but also provides buffering support for the follow-up of the W-axis or Z-axis. This multi-axis linkage ability enables the equipment to machine more complex and precise workpiece shapes. Through the cooperation of the buffer follow-up mechanism, the follow-up of the W-axis or Z-axis is more smooth and precise, improving the processing flexibility and adaptability of the equipment.

[0066] The bed 1 is provided with a U-axis automatic tool setting device 7, and the U-axis automatic tool setting device 7 realizes the automatic control of the tool setting position by displacing along the X direction.

[0067] It should be noted that: the U-axis automatic tool setting device 7 can accurately displace along the X direction, ensuring the accurate relative position between the tool and the workpiece, reducing the processing errors caused by tool setting errors, improving the processing accuracy, eliminating the need for manual repeated adjustment, saving time, improving the processing efficiency, reducing the production cost, and realizing continuous processing. The U-axis automatic tool setting device 7 can displace along the X direction to adapt to the processing requirements of workpieces with different sizes and shapes, improving the versatility and flexibility of the equipment. The U-axis automatic tool setting device 7 can be linked with other axes, enabling the machining of more complex and precise workpieces. By accurately setting the tool, improper vibration and impact are reduced, protecting the tool and the workpiece and extending their service lives. The U-axis automatic tool setting device 7 usually has functions of fault diagnosis and protection, improving the reliability and safety of the equipment.

[0068] Furthermore: the U-axis automatic tool setting device 7 is driven by a servo motor V, transmitted by a lead screw nut screw pair V, and linearly guided by an X-direction linear guide pair V to realize the automatic control of the X-direction tool setting position; the U-axis automatic tool setting device 7 is provided with an inductive tool setting probe, and the position of the inductive tool setting probe is automatically controlled through programming to realize the automatic control of the X-direction tool setting position.

[0069] It should be noted that: The servo motor V features high precision and high response speed, and can accurately control the displacement of the U-axis automatic tool setting device 7 in the X direction. Through the closed-loop control system, the servo motor V can adjust the output torque and speed in real time to ensure the accuracy of the U-axis automatic tool setting device 7. The screw-nut screw pair V has the advantages of high transmission efficiency and high positioning accuracy, and can accurately convert the rotational motion of the servo motor V into a linear motion. The self-locking property of the screw pair helps to maintain the position stability during the tool setting process and prevent displacement caused by external forces. The linear guide pair V provides a stable linear motion guide for the U-axis automatic tool setting device 7, reducing friction and resistance during the motion process. The equipped high-rigidity X-direction linear guide pair V helps to ensure the straightness and parallelism of the tool setting device in the X direction and improve the tool setting accuracy.

The high sensitivity and high accuracy of the probe help to ensure the accuracy and reliability of the tool setting process. Through programming, automatic control of the position of the inductive tool setting probe and automation of the tool setting process can be achieved. Programming control helps to reduce tool setting errors caused by human factors and improve the consistency and stability of machining. The automated tool setting process reduces the time for manual adjustment and increases the tool setting speed. In mass production, rapid tool setting can significantly improve machining efficiency and reduce production costs. The U-axis automatic tool setting device 7 can flexibly adjust the tool setting position to adapt to the machining requirements of workpieces with different sizes and shapes. Through programming control, automatic tool setting for different workpieces can be conveniently achieved, improving the versatility and flexibility of the equipment. The precise transmission and guiding system helps to reduce vibration and impact during the tool setting process and protect the tool and the workpiece. The stable U-axis automatic tool setting device 7 helps to reduce errors and scrap rates during the machining process and improve the machining quality. The servo motor V and the control system usually have fault diagnosis and protection functions, and can stop the machine and give an alarm in time when a fault occurs in the equipment, which helps to prevent equipment damage and safety accidents and improve the reliability and safety of the equipment. The modular design facilitates the disassembly and replacement of components, reducing the maintenance difficulty and cost. The programming control interface is usually intuitive and easy to understand, and the operator can conveniently set and adjust the tool setting parameters. The automated tool setting process reduces manual intervention, lowering the operation difficulty and labor intensity.

[0070] Furthermore: On one side of the bed body 1 corresponding to the workpiece spindle 5, there is a manipulator mounting surface 6 for mounting an automated manipulator; on the vacant surface of the bed body 1, there is an accessory mounting isolation area 12 for mounting hydraulic, pneumatic, and lubrication accessories.

[0071] It should be noted that by installing an automated manipulator, automatic loading and unloading of workpieces can be achieved, reducing manual intervention and improving processing efficiency. The automated manipulator can precisely control the grasping and placement positions of workpieces, reducing errors caused by improper manual operation. The automated manipulator can be programmed and adjusted according to different workpiece shapes and sizes to adapt to various processing requirements. When changing the processed workpiece, the automated manipulator can quickly adjust the program to achieve rapid changeover and improve production flexibility. The automated manipulator can replace manual operation in dangerous areas, preventing workers from contacting dangerous sources such as cutting fluid and high-temperature components. By reducing manual operation, the risk of work-related injuries caused by improper operation can be reduced.

[0072] By centrally installing hydraulic, pneumatic, and lubrication accessories in an isolation area, the equipment layout can be optimized and pipeline chaos can be reduced. Centralized installation makes the maintenance and management of accessories more convenient, facilitating the inspection and replacement of faulty components. Through the design of the isolation area, the mutual interference between hydraulic, pneumatic, and lubrication accessories can be reduced, improving the stability of the equipment. A reasonable layout and isolation design help reduce the failure rate of accessories and extend the service life of the equipment. The design of the isolation area can provide better heat dissipation conditions for the accessories, avoiding performance degradation or failures caused by overheating. A reasonable layout helps enhance the ventilation effect of the equipment and reduce potential safety hazards caused by heat accumulation.

[0073] The collaborative work of the automated manipulator and accessories can improve the overall processing efficiency and reduce downtime caused by manual operation or accessory failures. Through the flexible configuration of the automated manipulator and accessories, various processing requirements can be met, improving the versatility and flexibility of the equipment. The automated manipulator can reduce labor costs, and the centralized installation and isolation design of accessories can reduce maintenance costs, thus reducing the overall production cost. The reasonable design of the automated manipulator and accessories can improve the safety and reliability of the equipment, reducing safety accidents and downtime caused by improper operation or accessory failures.

[0074] The present invention also claims a method for using an internal meshing numerically controlled high-power honing machine, including an internal meshing numerically controlled high-power honing machine. The method for using the honing machine includes the following steps:

[0075] S1. During processing, the workpiece is connected to the workpiece spindle 5 through the tooling fixture 23. The Z-axis slide 4 moves along the Z direction to the position of the U-axis automatic tool setting device 7. The U-axis automatic tool setting device 7 drives the inductive tool setting probe to move near the outer circle of the workpiece through the servo motor V. The workpiece spindle 5 rotates to complete the workpiece phase measurement.

[0076] In step S1, the inductive tool setting probe can accurately detect the outer circle position of the workpiece, providing an accurate reference for subsequent phase measurement. The high sensitivity and high precision of the probe help to ensure the accuracy of phase measurement and reduce errors. The servo motor V can precisely control the movement of the tool setting probe to ensure stable positioning of the probe near the outer circle of the workpiece. Through the closed-loop control system, the servo motor V can adjust the output in real time to cope with the minor unevenness on the workpiece surface, improving the accuracy of phase measurement. The U-axis automatic tool setting device 7 can automatically complete the movement and positioning of the tool setting probe without manual intervention, improving the processing efficiency. The rotation of the workpiece spindle 5 and the movement of the tool setting probe work together to achieve fast and accurate phase measurement. The automated operation reduces the phase measurement errors caused by improper manual operation, improving the consistency and stability of processing. The fixture 23 is usually designed with a certain degree of versatility to adapt to the processing requirements of workpieces with different sizes and shapes. By replacing or adjusting the fixture, the phase measurement of different workpieces can be easily achieved. The numerical control system can control the movement trajectory and measurement parameters of the tool setting probe through programming to adapt to the processing requirements of different workpieces. This flexibility enables the internal meshing CNC high-power honing machine to machine more complex and precise workpieces. The precise transmission and guiding system helps to reduce the vibration and impact of the tool setting probe during movement, protecting the probe and the workpiece. The automated tool setting and phase measurement process reduces the processing preparation time, enabling the equipment to enter the processing state faster.

[0077] S2. After the A-axis shaft intersection angle adjustment shaft 10 is relaxed, the servo motor IV 9 drives the B-axis honing wheel spindle 11 to rotate the A-axis shaft intersection angle adjustment shaft 10 to the required angle, and the A-axis shaft intersection angle adjustment shaft 10 is locked. The B-axis honing wheel spindle 11 and the A-axis shaft intersection angle adjustment shaft 10 move to the safe position along with the X-axis honing head slide 22. The workpiece moves to the processing position along the Z direction following the Z-axis slide 4. The tailstock center protruding from the tailstock 13 moves to the processing position along with the W-axis tailstock slide 16 and tightens the workpiece.

[0078] In step S2, the A-axis intersection angle adjustment shaft 10 is relaxed. The servo motor Ⅳ9 can accurately drive the B-axis honing wheel spindle 11 to rotate to the required angle. The high-precision control of the servo motor Ⅳ9 ensures the accuracy of the A-axis intersection angle, providing a reliable positioning basis for subsequent honing processing. After the A-axis intersection angle adjustment shaft 10 rotates to the required angle, it is locked, ensuring the stability of the angle during the processing and avoiding processing errors caused by angle changes. The B-axis honing wheel spindle 11 and the A-axis intersection angle adjustment shaft 10 move to a safe position along with the X-axis honing head slide 22. At the same time, the workpiece moves to the processing position along the Z-axis with the Z-axis slide 4. This multi-axis linkage positioning method improves the processing efficiency and reduces the positioning time caused by moving each axis separately. The tailstock center protruding from the tailstock 13 moves to the processing position and presses against the workpiece along with the W-axis tailstock slide 16, ensuring the stability and support of the workpiece during the processing. The synchronous pressing operation of the tailstock avoids processing errors and safety accidents caused by workpiece loosening. By adjusting the positions of the Z-axis slide 4 and the X-axis honing head slide 22, the relative position between the workpiece and the honing wheel can be flexibly changed to meet the requirements of different processing scenarios. The precise transmission and guiding system helps to reduce the vibration and impact of each axis during movement, protecting the equipment and the workpiece. The stable processing environment helps to improve the processing accuracy and surface quality. The pressing operation of the tailstock enhances the rigidity of the workpiece during the processing and reduces the processing errors caused by workpiece deformation. At the same time, the locking mechanisms of each axis also ensure the stability of the equipment during the processing. The multi-axis linkage positioning and the synchronous pressing operation of the tailstock reduce the processing preparation time, enabling the equipment to enter the processing state faster, helping to improve the overall processing efficiency and reduce the production cost.

[0079] S3. The workpiece spindle 5 and the B-axis honing wheel spindle 11 rotate at a set high speed. The workpiece moves continuously along the Z-axis with the Z-axis slide 4, and the tailstock 13 moves continuously along the Z-axis with the W-axis tailstock slide 16. The B-axis honing wheel spindle 11 and the A-axis intersection angle adjustment shaft 10 move continuously along the X-axis with the X-axis honing head slide 22. The workpiece processing or honing wheel dressing is realized through the interpolation linkage of the rotation of the workpiece spindle 5, the rotation of the B-axis honing wheel spindle 11, the movement of the workpiece spindle 5 along the Z-axis, and the movement of the tailstock 13 along the Z-axis.

[0080] In step S3, the workpiece spindle 5 and the B-axis honing wheel spindle 11 rotate at high speed according to the set speed, significantly improving the machining or dressing speed, shortening the machining cycle. The high-speed rotation also helps to reduce the cutting force, lower the thermal deformation of the workpiece, and improve the machining accuracy. The workpiece moves continuously along the Z direction following the Z-axis slide 4, and the tailstock 13 moves along the Z-axis tailstock slide 16 of the W-axis. At the same time, the B-axis honing wheel spindle 11 and the A-axis axis intersection angle adjustment axis 10 move continuously along the X direction following the X-axis honing head slide 22. This multi-axis continuous movement mode enables the equipment to machine more complex and precise workpiece shapes, meeting diverse machining requirements. The high-precision interpolation linkage control can ensure the coordinated movement between axes and reduce machining errors caused by asynchronous movement. Real-time adjustment to adapt to machining changes enables the equipment to adapt to the machining requirements of workpieces with different materials and shapes. The multi-axis continuous movement and interpolation linkage technology endow the equipment with higher flexibility during machining, enabling it to easily handle various complex machining tasks. By adjusting the movement parameters of each axis, it is convenient to achieve the machining of different workpieces or the dressing of honing wheels.

[0081] S4. After the machining is completed, while maintaining the linkage, the B-axis honing wheel spindle 11 and the A-axis axis intersection angle adjustment axis 10 return to the safe position following the X-axis honing head slide 22, and the workpiece returns to the installation position following the Z-axis slide 4 for the installation of a new workpiece.

[0082] In this step S4, returning to the safe position, this linkage return method ensures the stability and safety of the equipment during the return process, avoiding impacts and vibrations caused by moving each axis separately. The rapid positioning function can improve production efficiency and reduce the waiting time caused by slow equipment return or inaccurate positioning. The workpiece returns to the installation position following the Z-axis slide 4, facilitating the operator to install a new workpiece, making the workpiece replacement process more convenient and reducing the downtime caused by difficult workpiece replacement. After the equipment returns to the safe position, it provides a more spacious and safe working space for the operator, facilitating the installation and debugging of a new workpiece. Through the smooth linkage return mechanism, the wear and failure risks of the equipment during the return process are reduced. After the equipment returns to the safe position, potential safety hazards caused by the equipment being in the machining position are avoided. The linkage return and positioning process of the equipment is automatically controlled by the numerical control system, simplifying the operation process. The precise control of the numerical control system ensures the accuracy of the equipment return and positioning. The equipment quickly returns to the safe position and is ready for the installation of a new workpiece, making the production process more compact and efficient, and reducing the production interruption time caused by equipment return and workpiece replacement. By quickly replacing the workpiece and adjusting the equipment parameters, it is possible to quickly switch to a new machining task.

[0083] Furthermore: (Combined with Figure 2 ) It also includes the step of adjusting the tailstock axis to be at the same height as the honing wheel axis before machining:

[0084] S01. Prepare a wrench tool and loosen the bolts that eccentrically mount the tailstock 13 on the tailstock housing 14.

[0085] S02. Determine the direction in which the tailstock 13 needs to be adjusted according to the relative position of the tailstock axis and the honing wheel axis, and prepare to rotate the tailstock 13 upward or downward.

[0086] S03. Use a tool to rotate the tailstock 13. Utilize the characteristics of the eccentric structure to move the tailstock axis. During the rotation of the tailstock 13, observe the change of the tailstock axis for timely adjustment.

[0087] S04. During the adjustment process, use a measuring tool, a laser rangefinder, to measure the height difference between the tailstock axis and the honing wheel axis, and ensure that they are at the same height. When the desired height is reached, stop rotating the tailstock 13.

[0088] S05. After the adjustment is completed, use bolts to fix the tailstock 13 to the tailstock housing 14 to prevent the tailstock 13 from moving during use.

[0089] It should be noted that: By precisely adjusting the tailstock axis and the honing wheel axis to be at the same height, the machining errors caused by inconsistent axis heights can be eliminated, and the machining accuracy can be improved; the equal height ensures the stability of the workpiece during the machining process, and reduces the vibration and deformation caused by axis deviation; the axis equal height adjustment ensures that each workpiece is under the same machining conditions during machining, improves the machining consistency, helps to reduce the dimensional deviation and shape error in batch machining, and improves the product quality. The eccentric mounting structure of the tailstock 13 makes the adjustment process simpler and faster; during the adjustment process, the change of the tailstock axis can be observed in real time and adjusted in a timely manner according to needs. This real-time feedback mechanism improves the accuracy and efficiency of the adjustment. The use of measuring tools such as laser rangefinders ensures the accuracy of the adjustment process. By measuring the height difference between the tailstock axis and the honing wheel axis, it can be accurately judged whether the adjustment reaches the desired height. After the adjustment is completed, use bolts to fix the tailstock 13 to the tailstock housing 14 to prevent the tailstock from moving during use, enhance the reliability of the equipment, and avoid machining errors and safety accidents caused by the movement of the tailstock. The axis equal height adjustment ensures the stability of the equipment during the machining process, reduces equipment failures and safety hazards caused by axis deviation, and helps to protect the safety of operators and equipment. By improving the machining accuracy and consistency, the scrap rate caused by machining errors is reduced, the production cost is lowered, and the production efficiency is increased. The simple and fast adjustment process shortens the production preparation time, improves the production efficiency, helps to optimize the production process, and reduces production interruptions caused by too long adjustment time.

At the same time, the hydraulic, lubrication, and pneumatic accessories of the machine tool are integrated with the machine tool, reducing the floor space of the machine tool and making the structure compact.

A broaching mechanism for automatically clamping the workpiece is provided to realize the high-precision automatic clamping of the workpiece, and it can also be used for the automatic clamping of the tool for dressing.

[0093] The X, Z, and W axes of the present invention are all driven by linear motors or servo motors to realize high-speed movement and the precise position control of large torque.

[0094] The A-axis intersection angle adjustment shaft 10 of the present invention is connected to the honing head slide 22 of the X-axis by a main support, an auxiliary support, and an adjustment shim II, and is configured with a brake device, a high-ratio speed reducer, and a hydraulic locking device, greatly enhancing the system rigidity of the A-axis intersection angle adjustment shaft 10, realizing high-precision positioning, efficient transmission, safety protection, stable locking, enhancing the system stability, and being easy to adjust and maintain.

[0095] The tailstock 13 of the present invention is provided with an eccentric structure, which cooperates with the tailstock adjustment seat 15 to realize the equal-height adjustment of the tailstock axis and the honing wheel axis, and realize the fine adjustment of the tailstock 13 during the workpiece machining process, improving the machining accuracy, ensuring the machining quality, having a compact structure, good stability, being easy to adjust, and convenient to maintain.
