Description

Technical Field

[0001] The invention relates to the technical field of boring machines, and in particular to a boring machine simulation cutting force loading device and a loading method. Background Art

[0002] A boring machine is a machine tool mainly used for hole processing. Its processing principle is to use the tool to rotate and move in the workpiece to process the hole. The boring machine mainly uses a boring cutter to bore the prefabricated holes of the workpiece. It is the main equipment for processing large box parts. Boring machines are widely used in many fields, such as aviation, automobiles, machine tools, electronics, chemicals, etc. In these fields, boring machines are mainly used to process high-precision holes or complete the finishing of multiple holes in one positioning, as well as to engage in the processing of other processing surfaces related to hole finishing. In order to ensure the accuracy of the boring machine in processing, it is necessary to simulate the loading of the cutting force of the boring machine.

[0003] In the prior art, a Chinese patent with announcement number CN105865823B discloses a three-axis boring machine simulation cutting force loading device and a method of use to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: it includes a rigid frame, an X-axis position adjustment component, a Y-axis cutting force loading component, a Z-axis position adjustment component and a tool rotation cutting force loading component. The method steps are: hoisting the simulation cutting force loading device onto the machine tool workbench, adjusting and fixing the position of the simulation flat disk through the X-axis and Z-axis position adjustment components, and fixing the simulation flat disk and the boring bar on the machine tool flat disk; setting a set of cutting forces, respectively adjusting the Y-axis and Z-axis position adjustment components through a torque wrench The tool rotates to tighten the pre-tightening bolts in the cutting force loading assembly to make the friction force in the cutting force loading assembly equal to the set cutting force. Since the friction force cannot be read directly, the tightening torque must be calculated using the formula M=KFd / μ and then read; start the machine tool and run the machining program to truly simulate the actual operating state of the machine tool under force conditions and test the machine tool performance under the current cutting force conditions. However, when connecting the equipment, the movable plate and the fixed plate are connected by bolts. This connection method requires the device to overcome the friction force while overcoming the influence of the bolts on the movable plate and the fixed plate, which will affect the accuracy of the test results of the device. Summary of the invention

[0004] The object of the present invention is to provide a boring machine simulated cutting force loading device and loading method to solve the problem in the above-mentioned background technology that the connection between the top plate and the moving plate is made by bolts, which causes the device to overcome other forces besides friction during the test.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A boring machine simulated cutting force loading device comprises a mounting frame for mounting the whole device, and guide rails for guiding the sliding bracket to perform horizontal displacement are symmetrically fixedly mounted on both sides of the mounting frame, and the sliding bracket guides the sliding plate to perform vertical displacement along the guide groove through a guide groove opened on one side; a magnetic coupling component, the magnetic coupling component is slidably mounted on the sliding plate, the magnetic coupling component comprises a sliding seat, the sliding seat is slidably connected to the inside of the sliding plate, a mounting seat is provided on the top of the sliding seat, and one end of the mounting seat passes through the side wall of the sliding plate and is fixedly connected to the sliding seat, a magnetic coupler is fixedly mounted on the top of the mounting seat through a limiting cover plate, and a connecting seat is fixedly mounted on the end of the magnetic coupler away from the mounting seat; a connecting component, the connecting component is rotationally connected to the connecting seat; a positioning locking component, the positioning locking component is fixedly mounted on one side of the connecting component, and is used to guide the boring machine spindle to connect with the magnetic coupling component; a display component, the display component is mounted on the bottom end of the sliding seat.

[0007] By adopting the above technical solution, in the process of simulating the cutting force of the boring machine, the staff first hoisted the entire device to the vicinity of the output spindle of the boring machine and firmly fixed it in an appropriate position to ensure the stability and safety of the operation. Subsequently, using the guide rail and sliding bracket system, the staff can flexibly adjust the precise position of the magnetic coupling component, the connecting component, the positioning locking component and the display component. This process not only improves the flexibility of installation, but also enhances the adaptability between the device and the boring machine spindle. In addition, through the precise operation of the positioning locking component, the magnetic coupling component can be tightly and accurately calibrated with the output spindle of the boring machine and connected between components. This process not only ensures high-precision docking between the two, but also avoids additional vibration and wear caused by eccentricity, thereby improving the accuracy and reliability of simulated loading. With the successful connection of the magnetic coupling component, A stable and efficient energy transmission channel is formed between the device and the boring machine, laying a solid foundation for the subsequent cutting force simulation loading test. During the test phase, the display component accurately controls and monitors the voltage and current input of the magnetic coupling component, and then adjusts the specific load force of the magnetic coupler. By adjusting the voltage and current parameters in real time, the cutting force characteristics of the boring machine under different working conditions can be more realistically reflected. The loading simulation device also brings many beneficial effects: First, its high flexibility and adjustability enable the device to be applicable to boring machines of various models and specifications, enhancing its versatility and applicability; secondly, precise concentricity calibration and stable connection design reduce errors and uncertainties in the test process and improve the reliability of the test results; finally, through simulated loading tests, potential cutting problems can be discovered and solved in advance, reducing downtime and cost losses in actual production.

[0008] A further improvement of the technical solution of the present invention is that: the connecting assembly includes a connecting sleeve, which is rotatably connected to the connecting seat, the outer ring of the connecting sleeve is fixedly installed with an outer ring sleeve through a plurality of connecting ribs, and connecting ribs are symmetrically fixedly installed on both sides of the outer ring sleeve, and one end of the two connecting ribs is fixedly installed with a sliding rod, and the end parts of the two sliding rods are respectively slidably matched with the matching seats, and the ends of the two matching seats away from the sliding rods are respectively slidably connected to the guide groove on one side of the sliding bracket.

[0009] By adopting the above technical solution, in the process of fine-tuning the layout of the magnetic coupling component, the positioning locking component and the display component, the staff uses the linkage between the guide rail and the sliding bracket to achieve precise control of the position of the magnetic coupling component. This design not only improves the operating efficiency, but also enhances the flexibility and adaptability of the system. In addition, in order to further optimize the synergy between the magnetic coupling component and the positioning locking component in the dynamic process, especially when the magnetic coupling component moves along the guide rail and the sliding bracket, the two sides of the positioning locking component are equipped with telescopically adjustable sliding rods and precision matching seats, thereby achieving precise fine-tuning of the positioning locking component in the horizontal direction. At the same time, the smooth sliding connection between the matching seat and the sliding bracket gives the positioning locking component the ability to freely adjust in the vertical direction. This multi-dimensional adjustment mechanism enhances the adaptability and stability of the device during assembly.

[0010] A further improvement of the technical solution of the present invention is that the slide bar is arranged in a rectangular shape, and the end of the matching seat is provided with a rectangular matching groove which is slidably matched with the slide bar.

[0011] By adopting the above technical solution, the rectangular slide rod and the matching rectangular matching groove on the matching seat constitute a highly precise and stable telescopic system. This design not only ensures the linearity and accuracy of the slide rod when it is extended and retracted in the matching seat, but also greatly enhances the degree of fit between the two. Therefore, in the process of adjusting the position of the positioning and locking assembly, whether it is fine-tuning in the horizontal direction or lifting and lowering in the vertical direction, it can achieve smoother and more reliable movement, further improving the overall performance and reliability of the equipment.

[0012] A further improvement of the technical solution of the present invention is that the positioning locking component includes a mounting base, one side of the mounting base is fixedly connected to one side of the outer ring sleeve, two limiting ear plates are symmetrically fixedly installed inside the mounting base, the inside of the mounting base is rotatably connected to a transmission gear ring through the limiting ear plates, a fixing ring is fixedly installed on one end of the mounting base away from the outer ring sleeve, the inner ring of the fixing ring is rotatably connected to a rotating plate, one side of the rotating plate is fixedly connected to the side wall of the transmission gear ring, three fixing seats are equidistantly fixedly installed on one side of the rotating plate away from the mounting base, guide rods are fixedly installed on one side of the three fixing seats, and there are three guide rods between them. The sliding connection is provided with a sliding sleeve, and a guide wheel is fixedly installed at one end of the three sliding sleeves away from the guide rod, and a guide column is fixedly installed on one side of the three guide wheels. A plurality of sliding guide grooves are equidistantly provided on the rotating plate close to the guide wheel, and sliding grooves are provided on one side of the mounting base and the fixed ring. A fixed frame is slidingly connected in the sliding grooves at the top of the mounting base and the fixed ring, and a pawl is rotatably connected to the bottom end of the fixed frame through a torsion spring, and a ratchet ring with a pawl snap-fitting is fixedly installed on the outer ring of the transmission gear ring, a connecting structure is fixedly installed inside the mounting base, and a limiting structure snap-fitting with the transmission gear ring is fixedly installed inside the mounting base.

[0013] By adopting the above technical scheme, in the process of connecting the device with the boring machine spindle, the fixed frame is pulled along the slide groove to drive the transmission ring gear to perform circular motion through the cooperation of the pawl and the ratchet ring. As the transmission ring gear rotates, the transmission ring gear will drive the rotating plate to rotate. As the rotating plate rotates, the guide column will move along the guide groove deflected toward the center of the rotating plate. At this time, the guide column will drive the sliding sleeve to move synchronously along the guide rod toward the center of the rotating plate, thereby realizing the synchronous movement of the three guide wheels toward the boring machine spindle, realizing the centering adjustment of the spindle, and facilitating the docking of the connection structure in the device with the boring machine spindle, which can increase the accuracy of the connection between the device and the boring machine spindle, and further increase the accuracy of the data when the device simulates cutting force loading.

[0014] A further improvement of the technical solution of the present invention is that the limiting structure includes a connecting chamber, which is opened at one end of the inner part of the rotating plate, one end of the connecting chamber is slidably connected to the first piston plate, one end of the first piston plate is rotatably connected to a limiting ball, the other end of the connecting chamber is slidably connected to the second piston plate, one end of the rotating plate is threadedly connected to an adjusting bolt, and one end of the adjusting bolt passes through the side wall of the mounting base and is rotatably connected to one side of the second piston plate, and a plurality of limiting grooves that are engaged with the limiting balls are symmetrically opened on one side of the transmission gear ring close to the rotating plate.

[0015] By adopting the above technical solution, as the staff continues to drive the pawl and the ratchet ring through the fixed frame to rotate the transmission gear ring, since the sliding sleeve and the guide wheel have been in squeeze contact with the main shaft of the boring machine, at this time, the transmission gear ring is subject to a certain resistance when driving the rotating plate to rotate. At this time, the limiting ball will drive the first piston plate to move toward the connecting chamber, and then the limiting ball on the rotating plate will move out of the limiting groove at the transmission gear ring, releasing the connection relationship between the transmission gear ring and the rotating plate, so that the transmission gear ring can be separated from the rotating plate for rotation, and then the device can be connected to the main shaft of the boring machine through the transmission gear ring driving connection structure, and the segmented centering connection mechanism makes the device more stable and quick when connected to the main shaft of the boring machine.

[0016] A further improvement of the technical solution of the present invention is that a plurality of rubber pads are fixedly installed in a ring shape inside the limiting groove.

[0017] By adopting the above technical solution, the rubber pad arranged in an annular shape inside the limiting groove can reduce the vibration generated when the limiting ball impacts the inside of the limiting groove, and further reduce the impact caused by the periodic contact between the limiting ball and the limiting groove, thereby increasing the connection accuracy between the device and the boring machine spindle, making it more convenient for staff to use.

[0018] A further improvement of the technical solution of the present invention is that the connecting structure includes a rotating ring gear, which is rotatably connected to the inside of the mounting base, the outer ring of the rotating ring gear is equidistantly meshed with three transmission gears, and the three transmission gears are rotatably connected to the mounting base, the three transmission gears are meshed with the inner ring of the transmission ring gear, a connecting rod is fixedly installed in the center of the rotating ring gear, and one end of the connecting rod is fixedly connected to an end of the magnetic coupler away from the mounting base.

[0019] By adopting the above technical solution, as the staff continues to pull the fixed frame, the transmission ring gear will continuously rotate. As the transmission ring gear continues to rotate, the transmission ring gear will drive the rotating ring gear to rotate through the transmission gear. The rotating ring gear is fixedly connected to the connecting rod. As the rotating ring gear rotates, the connecting rod will follow and rotate. As the connecting rod continues to rotate, the connecting rod can be threadedly connected to the boring machine spindle, thereby completing the connection between the device and the boring machine spindle. The connection directions of the boring machine spindle and the connecting rod are opposite, so that the connection is more stable when the device cooperates with the boring machine spindle to rotate.

[0020] A further improvement of the technical solution of the present invention is that: the display component includes a mounting rod, the mounting rod is fixedly installed on the bottom end of the sliding seat, a horizontal plate is fixedly installed on the bottom end of the mounting rod, a clamping seat is symmetrically fixedly installed on the bottom end of the horizontal plate, one end of the magnetic coupler is electrically connected to a connecting wire, and the connecting wire is snap-fitted with the clamping seat, a mounting plate is fixedly installed on one side of the sliding bracket, a multimeter is fixedly installed on one side of the mounting plate, and the multimeter is electrically connected to one end of the connecting wire away from the clamping seat.

[0021] By adopting the above technical solution, the actual voltage and current input into the magnetic coupler can be detected in real time by a multimeter, and the connecting wires between the multimeter and the magnetic coupler are restrictively connected through the socket to increase the orderliness of the connection of the wiring harness when the device is in use.

[0023] S1. Install the loading device for simulating cutting force on the workbench of the target machine tool;

[0024] S2. The positions of the magnetic coupling component and the positioning locking component are adjusted by the guide rail and the sliding bracket. Subsequently, the concentricity of the output spindle of the boring machine is calibrated by the positioning locking component. The magnetic coupling component is connected to the output spindle of the boring machine by the positioning locking component during the concentricity calibration process.

[0025] S3. Data setting, select a set of cutting forces to be loaded, and according to the formula:

[0026] Calculate the working current of the magnetic coupler under the corresponding cutting force; adjust the actual working current of the magnetic coupler according to the calculated working current to make the two the same;

[0027] Where, F is the selected loading cutting force, is the magnetic permeability of the material, N is the number of turns of the coil, I is the current passing through the coil, A is the area of ​​the adsorbed bar, and L is the length of the magnetic circuit;

[0028] S4, start the boring machine and run the machining program, perform testing with the set cutting force and the simulated cutting force loading device, observe and record the performance and stability of the boring machine;

[0029] S5. Repeat multiple groups of experiments; change the selected cutting force to be loaded, and repeat the above steps S3 and S4 to complete the performance and stability measurement of the boring machine under different cutting forces.

[0030] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0031] 1. The contactless energy transmission achieved by the magnetic coupler in the present invention effectively avoids the test errors caused by friction and bolt influence in traditional bolt connections, and improves the accuracy and reliability of the test. Secondly, the flexibility and adjustability of the magnetic coupling component enable the device to easily adapt to boring machines of various models and specifications, enhancing the versatility and applicability. In addition, the high-precision concentricity calibration and stable connection design between the magnetic coupling component and the boring machine spindle not only reduce vibration and wear, but also extend the service life of the equipment. In summary, the magnetic coupling component, with its high precision, contactless, flexible and adjustable characteristics, provides solid technical support for the boring machine simulation cutting force loading test, ensuring the accuracy of the test results and the long-term stable operation of the equipment.

[0032] 2. In the docking process between the positioning locking assembly and the output spindle of the boring machine, the segmented centering connection mechanism of the present invention makes the connection between the device and the boring machine spindle more stable and quick. Through the limiting structure and the connecting structure, the device can be calibrated for concentricity with the boring machine spindle before connection, which makes the device more stable during operation, further increases the accuracy of the data, improves the efficiency of the device during use, and makes it more convenient for the staff to use the device to simulate the cutting force of the boring machine.

In addition, the connecting wires between the multimeter and the magnetic coupler use a card holder for restrictive connection, which not only enhances the connection stability of the wiring harness, but also effectively improves the orderliness of the wiring harness connection during the use of the device, reducing the safety hazards and maintenance difficulties caused by the disorderly wiring harness.

[0034] 4. In the present invention, the staff can flexibly adjust the contact pressure between the limiting ball and the limiting groove according to the actual working conditions to achieve dynamic balance and optimization of the pressure, which not only improves the adjustability of the device, but also greatly enhances its adaptability in complex and changeable application environments. The adjustment mechanism involves direct adjustment of the pressure, and also implies dynamic compensation for external factors such as contact surface wear and temperature changes, thereby ensuring the stability and long-term effectiveness of the equipment operation. In addition, it also facilitates the daily maintenance and adjustment work of the operator, reduces unnecessary downtime caused by fixed restrictions, and improves overall work efficiency and user experience.

[0035] 5.

[0053] The present invention is further described in detail below in conjunction with embodiments:

[0054] Example 1

[0055] like Figure 1-Figure 15 As shown, the present invention provides a boring machine simulation cutting force loading device, including a mounting frame 1, which is used to install the entire device, and guide rails 2 for guiding a sliding bracket 3 to perform horizontal displacement are fixedly installed symmetrically on both sides of the mounting frame 1, and the sliding bracket 3 guides a sliding plate 5 to perform vertical displacement along the guide groove 4 through a guide groove 4 opened on one side; a magnetic coupling component 6, the magnetic coupling component 6 is slidably installed on the sliding plate 5, and the magnetic coupling component 6 includes a sliding seat 10, the sliding seat 10 is slidably connected to the inside of the sliding plate 5, and a mounting seat 11 is provided on the top of the sliding seat 10, One end of the mounting seat 11 passes through the side wall of the sliding plate 5 and is fixedly connected to the sliding seat 10. A magnetic coupler 12 is fixedly installed on the top of the mounting seat 11 through a limiting cover plate 13, and a connecting seat 14 is fixedly installed on the end of the magnetic coupler 12 away from the mounting seat 11; a connecting component 7, the connecting component 7 is rotationally connected to the connecting seat 14; a positioning locking component 8, the positioning locking component 8 is fixedly installed on one side of the connecting component 7, and is used to guide the boring machine spindle to connect with the magnetic coupling component 6; a display component 9, the display component 9 is installed at the bottom end of the sliding seat 10.

[0056] In this embodiment, in the process of simulating the cutting force of the boring machine, the staff first hoisted the entire device to the vicinity of the output spindle of the boring machine and firmly fixed it in an appropriate position to ensure the stability and safety of the operation. Subsequently, using the guide rail 2 and the sliding bracket 3 system, the staff can flexibly adjust the precise positions of the magnetic coupling component 6, the connecting component 7, the positioning locking component 8 and the display component 9. This process not only improves the flexibility of installation, but also enhances the adaptability between the device and the boring machine spindle. In addition, through the precise operation of the positioning locking component 8, the magnetic coupling component 6 can be tightly and accurately calibrated with the output spindle of the boring machine and connected between components. This process not only ensures high-precision docking between the two, but also avoids additional vibration and wear caused by eccentricity, thereby improving the accuracy and reliability of simulated loading. With the successful connection of the magnetic coupling component 6 A stable and efficient energy transmission channel is formed between the device and the boring machine, which lays a solid foundation for the subsequent cutting force simulation loading test. During the test phase, the display component 9 accurately controls and monitors the voltage and current input of the magnetic coupling component 6, and then adjusts the specific load force of the magnetic coupler 12. By adjusting the voltage and current parameters in real time, the cutting force characteristics of the boring machine under different working conditions can be more realistically reflected. The loading simulation device also brings many beneficial effects: First, its high flexibility and adjustability enable the device to be applicable to boring machines of various models and specifications, enhancing its versatility and applicability; secondly, precise concentricity calibration and stable connection design reduce errors and uncertainties in the test process, and improve the reliability of the test results; finally, through simulated loading tests, potential cutting problems can be discovered and solved in advance, reducing downtime and cost losses in actual production.

[0057] Example 2

[0058] During the operation of the device, it is necessary to keep the magnetic coupling component 6 and the positioning locking component 8 at the same level at all times, so as to ensure the stability of the device operation during the cutting force loading process. Therefore, the positioning locking component 8 is required to be able to adjust the position in real time according to the magnetic coupling component 6. Therefore, a connecting component 7 is fixedly installed on one side of the positioning locking component 8 close to the side of the magnetic coupling component 6.

[0059] like Figure 8As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the connecting component 7 includes a connecting sleeve 15, which is rotatably connected to the connecting seat 14, and the outer ring of the connecting sleeve 15 is fixedly installed with an outer ring sleeve 17 through a plurality of connecting ribs 16, and connecting ribs 18 are symmetrically fixedly installed on both sides of the outer ring sleeve 17, and one end of the two connecting ribs 18 is fixedly installed with a sliding rod 19, and the ends of the two sliding rods 19 are respectively slidably matched with the matching seats 20, and the ends of the two matching seats 20 away from the sliding rod 19 are respectively slidably connected to the guide groove 4 on one side of the sliding bracket 3.

[0060] In this embodiment, in the process of finely adjusting the layout of the magnetic coupling component 6, the positioning locking component 8 and the display component 9, the staff uses the linkage between the guide rail 2 and the sliding bracket 3 to achieve precise control of the position of the magnetic coupling component 6. This design not only improves the operating efficiency, but also enhances the flexibility and adaptability of the system. In addition, in order to further optimize the synergy between the magnetic coupling component 6 and the positioning locking component 8 in the dynamic process, especially when the magnetic coupling component 6 moves along the guide rail 2 and the sliding bracket 3, the two sides of the positioning locking component 8 are equipped with telescopically adjustable sliding rods 19 and precision matching seats 20, thereby achieving precise fine-tuning of the positioning locking component 8 in the horizontal direction. At the same time, the smooth sliding connection between the matching seat 20 and the sliding bracket 3 gives the positioning locking component 8 the ability to freely adjust in the vertical direction. This multi-dimensional adjustment mechanism enhances the adaptability and stability of the device during assembly.

[0061] It should also be noted that: in the process of connecting the outer ring sleeve 17 and the connecting sleeve 15, the connecting rib rods 16 not only enhance the physical connection between the two, making the structure more stable, but also greatly improve the tightness of the fit, effectively preventing performance degradation due to looseness or excessive clearance. In addition, the design of these connecting rib rods 16 has another important advantage: while ensuring a high-strength connection between the connecting sleeve 15 and the outer ring sleeve 17, they reduce the weight of the overall installation by optimizing the structural layout. This feature not only makes the installation process more convenient, but also reduces the load requirements on the supporting structure, and improves the flexibility and adaptability of the entire device. Therefore, the design of the connecting rib rods 16 not only enhances the connection performance, but also optimizes the overall structure, providing strong support for the stable operation and efficient installation of the equipment.

[0062] In order to ensure that the positioning locking assembly 8 can remain stable when adjusting the horizontal direction in the left and right directions, the slide bar 19 and the matching seat 20 are arranged as follows;

[0063] like Figure 8 As shown, preferably, the slide bar 19 is arranged in a rectangular shape, and the end of the matching seat 20 is provided with a rectangular matching groove that is slidably matched with the slide bar 19 .

[0064] In this embodiment, the rectangular slide bar 19 and the matching rectangular matching groove on the matching seat 20 constitute a highly precise and stable telescopic system. This design not only ensures the linearity and accuracy of the slide bar 19 when it is extended and retracted in the matching seat 20, but also greatly enhances the degree of fit between the two. Therefore, in the process of adjusting the position of the positioning locking component 8, whether it is fine-tuning in the horizontal direction or lifting and lowering in the vertical direction, a smoother and more reliable movement can be achieved, further improving the overall performance and reliability of the equipment.

[0065] Example 3

[0066] like Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the positioning locking assembly 8 includes a mounting base 21, one side of the mounting base 21 is fixedly connected to one side of the outer ring sleeve 17, two limiting ear plates 22 are symmetrically fixedly installed inside the mounting base 21, the inside of the mounting base 21 is rotatably connected to a transmission gear ring 23 through the limiting ear plates 22, a fixing ring 25 is fixedly installed at one end of the mounting base 21 away from the outer ring sleeve 17, the inner ring of the fixing ring 25 is rotatably connected to a rotating plate 26, one side of the rotating plate 26 is fixedly connected to the side wall of the transmission gear ring 23, and three fixing seats 27 are equidistantly fixedly installed on one side of the fixing seat 27 away from the mounting base 21, and one side of the three fixing seats 27 is fixedly installed with guide rods 28. The three guide rods A sliding sleeve 29 is slidably connected between the guide rods 28, a guide wheel 30 is fixedly installed on one end of the three sliding sleeves 29 away from the guide rods 28, a guide column 31 is fixedly installed on one side of the three guide wheels 30, a plurality of sliding guide grooves 32 are equidistantly provided on the rotating plate 26 near the guide wheel 30, a sliding groove 33 is provided on one side of the mounting base 21 and the fixed ring 25, a fixing frame 34 is slidably connected in the sliding groove 33 at the top of the mounting base 21 and the fixed ring 25, a pawl 35 is rotatably connected to the bottom end of the fixing frame 34 through a torsion spring, a ratchet ring 24 with a pawl 35 snap-fitting is fixedly installed on the outer ring of the transmission gear ring 23, a connecting structure is fixedly installed inside the mounting base 21, and a limiting structure snap-fitting with the transmission gear ring 23 is fixedly installed inside the mounting base 21.

[0067] In this embodiment, during the process of connecting the device with the boring machine spindle, the fixed frame 34 is pulled along the slide groove 33 to drive the transmission ring gear 23 to perform circular motion through the cooperation of the pawl 35 and the ratchet ring 24. As the transmission ring gear 23 rotates, the transmission ring gear 23 will drive the rotating plate 26 to rotate. As the rotating plate 26 rotates, the guide column 31 will move along the guide groove 32 deflected toward the center of the rotating plate 26. At this time, the guide column 31 will drive the sliding sleeve 29 to move synchronously along the guide rod 28 toward the center of the rotating plate 26, thereby realizing the synchronous movement of the three guide wheels 30 toward the boring machine spindle, realizing the centering adjustment of the spindle, facilitating the docking of the connection structure in the device with the boring machine spindle, and can increase the accuracy of the connection between the device and the boring machine spindle, and further increase the accuracy of the data when the device simulates cutting force loading.

[0068] During the entire centering connection process, because the centering links of the connecting structure and the positioning locking assembly 8 cannot guarantee precise synchronization, when the connecting structure is connected to the boring machine spindle, in order to ensure the docking accuracy of the connection between the two, the device needs to complete the docking work before the connection is made. In this process, the integrity and consistency of the links need to be ensured, and the transmission gear ring 23 needs to be driven by the fixed frame 34 to drive the connecting structure to complete the connection step. When the fixed frame 34 is driven again, the transmission gear ring 23 will drive the rotating plate 26 to continue to rotate, and the continuous rotation of the rotating plate 26 will cause the guide column 31 to move along the guide groove 32. The guide wheel 30 and the main shaft are pressed and contacted with each other, which will limit the rotation of the rotating plate 26, and then make the transmission gear ring 23 unable to rotate. In summary, in the process of connecting with the main shaft through the connecting mechanism, the rotating plate 26 needs to be able to disengage from the transmission gear ring 23, so that the process of connecting the fixed frame 34 driving the connecting mechanism is smoother. Therefore, a limiting structure is provided between the transmission gear ring 23 and the rotating plate 26, so that when the driving connection structure is connected to the main shaft, the connection between the transmission gear ring 23 and the rotating plate 26 can be disengaged, so that it is more convenient to realize the connection between the main shaft through the fixed frame 34 driving the connecting structure;

[0069] like Fig.12 As shown, preferably, the limiting structure includes a connecting chamber 36, which is opened at one end of the inner part of the rotating plate 26, one end of the connecting chamber 36 is slidably connected to the first piston plate 37, one end of the first piston plate 37 is rotatably connected to the limiting ball 38, the other end of the connecting chamber 36 is slidably connected to the second piston plate 40, one end of the rotating plate 26 is threadedly connected to an adjusting bolt 39, and one end of the adjusting bolt 39 passes through the side wall of the mounting base 21 and is rotatably connected to one side of the second piston plate 40, and a plurality of limiting grooves 41 that are snap-fitted with the limiting balls 38 are symmetrically opened on one side of the transmission gear ring 23 close to the rotating plate 26.

[0070] In this embodiment, as the staff continues to drive the pawl 35 and the ratchet ring 24 through the fixed frame 34 to rotate the transmission gear ring 23, since the sliding sleeve 29 and the guide wheel 30 have been in squeeze contact with the boring machine spindle, at this time, the transmission gear ring 23 is subject to a certain resistance when driving the rotating plate 26 to rotate. At this time, the limiting ball 38 will drive the first piston plate 37 to move toward the connecting chamber 36, and then the limiting ball 38 on the rotating plate 26 will move out of the limiting groove 41 at the transmission gear ring 23, releasing the connection relationship between the transmission gear ring 23 and the rotating plate 26, so that the transmission gear ring 23 can be separated from the rotating plate 26 for rotation, and then the device can be connected to the boring machine spindle through the transmission gear ring 23 driving the connecting structure, and the segmented centering connection mechanism makes the device more stable and quick when connected to the boring machine spindle.

[0071] It should also be noted that: the staff can adjust the pressure between the first piston plate 37 and the second piston plate 40 by adjusting the bolt 39 in real time according to the use requirements, so as to adjust the contact pressure between the limiting ball 38 and the limiting groove 41, so as to adjust the rotation performance between the transmission gear ring 23 and the rotating plate 26, and the interior of the communication chamber 36 is filled with hydraulic oil;

[0072] The continuous rotation of the transmission gear ring 23 will cause the limiting groove 41 on one side of the transmission gear ring 23 to periodically contact the limiting ball 38. When the limiting ball 38 contacts the limiting groove 41, the pressure inside the connecting cavity 36 will cause the limiting ball 38 to quickly rush into the limiting groove 41. The rapid impact will cause the positioning locking assembly 8 to vibrate, and the vibration will cause the connection between the connecting mechanism and the boring machine spindle to be unstable. Therefore, it is necessary to reduce the influence of the vibration on the connecting mechanism and the boring machine spindle when the limiting groove 41 and the limiting ball 38 are in periodic contact.

[0073] like Fig.14 As shown, preferably, a plurality of rubber pads 42 are fixedly installed in a ring shape inside the limiting groove 41 .

[0074] In this embodiment, the rubber pad 42 arranged in an annular shape inside the limiting groove 41 can reduce the vibration generated when the limiting ball 38 impacts the inside of the limiting groove 41, and further reduce the impact caused by the periodic contact between the limiting ball 38 and the limiting groove 41, thereby increasing the connection accuracy between the device and the boring machine spindle, making it more convenient for staff to use.

[0075] like Figure 6 and Fig. 9As shown, preferably, the connection structure includes a rotating ring gear 43, which is rotatably connected to the inside of the mounting base 21, and the outer ring of the rotating ring gear 43 is equidistantly meshed with three transmission gears 44, and the three transmission gears 44 are rotatably connected to the mounting base 21, and the three transmission gears 44 are meshed with the inner ring of the transmission ring gear 23, and a connecting rod 45 is fixedly installed in the center of the rotating ring gear 43, and one end of the connecting rod 45 is fixedly connected to the end of the magnetic coupler 12 away from the mounting base 11.

[0076] In this embodiment, as the staff continues to pull the fixed frame 34, the transmission ring gear 23 will continuously rotate. As the transmission ring gear 23 continues to rotate, the transmission ring gear 23 will drive the rotating ring gear 43 to rotate through the transmission gear 44. The rotating ring gear 43 is fixedly connected to the connecting rod 45. As the rotating ring gear 43 rotates, the connecting rod 45 will follow and rotate. As the connecting rod 45 continues to rotate, the connecting rod 45 can be threadedly connected to the boring machine spindle, thereby completing the connection between the device and the boring machine spindle. The connection directions of the boring machine spindle and the connecting rod 45 are opposite, so that the connection is more stable when the device cooperates with the boring machine spindle to rotate.

[0077] Example 4

[0078] like Figure 7 and Fig.15 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the display component 9 includes a mounting rod 46, the mounting rod 46 is fixedly mounted on the bottom end of the sliding seat 10, a cross plate 47 is fixedly mounted on the bottom end of the mounting rod 46, a clamping seat 48 is symmetrically fixedly mounted on the bottom end of the cross plate 47, one end of the magnetic coupler 12 is electrically connected to a connecting wire 49, and the connecting wire 49 is snap-fitted with the clamping seat 48, a mounting plate 50 is fixedly mounted on one side of the sliding bracket 3, a multimeter 51 is fixedly mounted on one side of the mounting plate 50, and the multimeter 51 is electrically connected to one end of the connecting wire 49 away from the clamping seat 48.

[0079] In this embodiment, the actual voltage and current input into the magnetic coupler 12 can be detected in real time by the multimeter 51, and the connecting wire 49 between the multimeter 51 and the magnetic coupler 12 is restrictively connected through the socket 48 to increase the orderliness of the connection of the wiring harness when the device is in use.

[0080] The present invention also provides a method for loading a boring machine with simulated cutting force, comprising:

[0081] S1. Install the cutting force simulation loading device on the workbench of the target machine tool;

[0082] S2, adjusting the positions of the magnetic coupling assembly 6 and the positioning locking assembly 8 through the guide rail 2 and the sliding bracket 3, and then calibrating the concentricity of the output spindle of the boring machine through the positioning locking assembly 8, and completing the connection between the magnetic coupling assembly 6 and the output spindle of the boring machine through the positioning locking assembly 8 during the concentricity calibration process;

[0083] S3. Data setting, select a set of cutting forces to be loaded, and according to the formula:

[0084] Calculate the working current of the magnetic coupler 12 under the corresponding cutting force; adjust the actual working current of the magnetic coupler 12 according to the calculated working current so that the two are the same;

[0085] Where, F is the selected loading cutting force, is the magnetic permeability of the material, N is the number of turns of the coil, I is the current passing through the coil, A is the area of ​​the adsorbed bar, and L is the length of the magnetic circuit;

[0086] S4, start the boring machine and run the machining program, perform testing with the set cutting force and the simulated cutting force loading device, observe and record the performance and stability of the boring machine;

[0087] S5. Repeat multiple groups of experiments; change the selected cutting force to be loaded, and repeat the above steps S3 and S4 to complete the performance and stability measurement of the boring machine under different cutting forces.

[0088] It should be noted that: since the rated parameters of the magnetic coupling device 12 in the magnetic coupling assembly 6 are known, that is, The data such as the magnetic permeability of the material, A is the area of ​​the adsorption bar and L is the length of the magnetic circuit are all known data.

[0089] The working principle of the boring machine's simulated cutting force loading device is described in detail below.

[0090] like Figure 1-Figure 15As shown, in the process of simulating the cutting force of the boring machine, the staff first hoisted the entire device to the vicinity of the boring machine output spindle and firmly fixed it in an appropriate position to ensure the stability and safety of the operation. Then, using the guide rail 2 and the sliding bracket 3 system, the staff can flexibly adjust the precise positions of the magnetic coupling component 6, the connecting component 7, the positioning locking component 8 and the display component 9. After adjusting to the appropriate position, the staff will sleeve the positioning locking component 8 on the outside of the boring machine output spindle. At this time, the staff will move the positioning locking component 8 toward the boring machine spindle. Then, the staff will start to pull the fixing frame 34 along the mounting base 21 and the rotating plate 26 to open The sliding groove 33 moves, at this time, the pawl 35 at the bottom of the fixing frame 34 cooperates with the ratchet ring 24 to drive the transmission gear ring 23 to rotate. With the rotation of the transmission gear ring 23, the transmission gear ring 23 will drive the rotating plate 26 to rotate. With the rotation of the rotating plate 26, the guide groove 32 provided on the rotating plate 26 will cooperate with the guide column 31 to guide the sliding sleeve 29 to move toward the center of the rotating plate 26. As the three sliding sleeves 29 move toward the center synchronously, the sliding sleeve 29 and the boring machine spindle are adjusted to be centered. In order to increase the adjustment effect of the sliding sleeve 29 on the boring machine spindle, a guide wheel 30 for driving with the boring machine spindle is installed at the end of the sliding sleeve 29.

[0091] After completing the centering adjustment, the staff still needs to connect the rear boring machine spindle with the device through the positioning locking assembly 8. The staff continues to drive the pawl 35 and the ratchet ring 24 through the fixing frame 34 to rotate the transmission gear ring 23. Since the sliding sleeve 29 and the guide wheel 30 have been squeezed and contacted with the boring machine spindle, at this time, the transmission gear ring 23 encounters a certain resistance when driving the rotating plate 26 to rotate. At this time, the limiting ball 38 will drive the first piston plate 37 to move toward the connecting chamber 36, and then the limiting ball 38 on the rotating plate 26 will move out of the limiting groove 41 on the transmission gear ring 23, releasing the connection between the transmission gear ring 23 and the rotating plate 26, so that the transmission gear ring 23 can be separated from the rotating plate 26 for rotation, and then it can The device is connected to the main shaft of the boring machine by driving the connecting structure through the transmission gear ring 23. As the staff continues to pull the fixed frame 34, the transmission gear ring 23 will rotate continuously. As the transmission gear ring 23 continues to rotate, the transmission gear ring 23 will drive the rotating gear ring 43 to rotate through the transmission gear 44. The rotating gear ring 43 is fixedly connected to the connecting rod 45. As the rotating gear ring 43 rotates, the connecting rod 45 will rotate accordingly. As the connecting rod 45 continues to rotate, the connecting rod 45 can be threadedly connected to the main shaft of the boring machine, thereby completing the connection between the device and the main shaft of the boring machine. Subsequently, the actual voltage and current input into the magnetic coupler 12 can be detected in real time by the multimeter 51, and the formula is used to Calculate the cutting forces.

[0092] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
