Description

Technical Field

[0001] This application relates to the field of cutting machine tool technology, and in particular to a precision forming internal cyclone cutting machine tool and its method of use. Background Technology

[0002] In the field of modern precision machinery manufacturing, high-precision and high-efficiency forming of large cylindrical and tubular workpieces is a key and challenging process. Internal cyclone cutting technology, as an advanced internal surface machining method, uses multiple forming tools mounted on a high-speed rotating cutter head to continuously cut the inner wall of a fixed or slowly rotating workpiece. It offers significant advantages such as high processing efficiency, good surface quality, and easily guaranteed forming accuracy.

[0003] However, existing internal cyclone cutting machine tools, to ensure safety and prevent chip splashing, have the cutter head and its cutting area located inside the machine head, typically with a protective housing or cover on the outside. While this enclosed structure ensures safety, it makes it difficult for operators to directly observe the real-time working status and wear of the tools on the cutter head, as well as the immediate morphology of the workpiece during machining. This inconveniences monitoring and adjustment of the machining process, affecting machining quality and efficiency. Therefore, this paper proposes a precision-formed internal cyclone cutting machine tool and its usage method to solve the problems mentioned above. Summary of the Invention

[0004] In view of the shortcomings of the prior art, and in order to facilitate the observation of the tool after retraction, this application provides a precision-forming internal cyclone cutting machine tool and its usage method, which has the advantages of easy observation and accurate measurement inside the narrow tool head, and solves the problems mentioned above.

[0005] This application provides a precision forming internal cyclone cutting machine tool and its usage method, adopting the following technical solution:

[0013] Optional: The abutting member includes an abutting shaft, a ball bearing is rotatably mounted at the bottom end of the abutting shaft, a receiving cavity is provided inside the detection mounting base, a return spring extending into the receiving cavity is fixed at the top end of the abutting shaft, a connecting block is fixed on the top side of the detection mounting base, and a mounting sleeve that is sleeved on the outside of the drive assembly is provided on one side of the connecting block, wherein a guide rod is elastically installed between the connecting block and the mounting sleeve;

[0014] The external part of the detection mounting base is also provided with a clamping component and a contact component for use with the contact component. The contact component includes an electric telescopic rod, a slide fixed to the output end of the electric telescopic rod, and an inclined seat fixed to the top side of the slide. The ball bearings are in contact with the inclined seat.

[0015] Optionally: The clutch seat is rotatably installed inside the transmission groove, wherein the centrifugal block in the first drive assembly generates centrifugal displacement through the rotation of the rotor and abuts against the clutch seat, causing the clutch seat to rotate; the second connecting arm extends through the sliding port into the inside of the cover; the end of the second connecting arm is fixed with a toothed plate; the outside of the toothed plate is engaged with a drive gear fixed to the second drive assembly.

[0016] Optionally: The second drive assembly includes a hollow guide cylinder and a guide tube. A lifting shaft is provided inside the guide tube.

[0017] The guide tube has a spiral guide groove inside and surrounding its outer surface.

[0018] Optionally: the clamping assembly includes a limiting sleeve and a guide sleeve with a hollow interior, and the guide sleeve and the limiting sleeve are slidably connected;

The inner side of the guide sleeve and the outer wall of the elastic block are provided with a guide slope for abutting cooperation. A first connecting rod is hinged between the guide sleeve and the abutting shaft.

[0020] Another problem that this invention also needs to solve is to provide a method for using a precision-forming internal cyclone cutting machine tool, including the following steps:

[0021] S1. Preparations:

[0022] First, confirm that all parts of the machine tool are in good condition and adequately lubricated. Pay special attention to checking the conveying equipment, end fixing mechanism, side fixing mechanism, cutting mechanism cutter head, retraction mechanism, drive motor, and cooling and detection system.

[0023] The workpiece to be processed is then smoothly conveyed to the designated processing position on the machine base via the tail conveyor.

[0024] Next, install and calibrate the tool turret, and confirm that the CNC program or machining parameters are set correctly;

[0025] S2. Workpiece fixing:

[0026] Activate the end-fixing mechanism to firmly clamp one end of the workpiece;

[0027] Then the side fixing mechanism is activated, and its servo electric cylinder stabilizer applies clamping force from the side of the workpiece to achieve all-round rigid fixing;

[0028] S3. Cutting and Coordination Motions:

[0029] First, start the drive motor, which drives the cutter head to rotate at high speed through the connecting shaft and transmission gear;

[0030] Then start the electric slide table to drive the machine head and cutter head to feed along the workpiece axis for internal cyclone cutting;

[0031] During cutting, the connecting shaft rotates at high speed, driving the external rotor to rotate synchronously; the centrifugal blocks on the rotor slide outward under the action of centrifugal force, and push the sleeve through the connecting arm, eventually causing the centrifugal blocks to press against the inner wall of the clutch seat to generate friction, thereby driving the clutch seat to rotate;

[0032] The clutch seat drives the impeller to rotate, providing forced air cooling for the drive motor;

[0033] At the same time, the second connecting arm swings, pushing the meshing toothed plate to move in a straight line, and the toothed plate drives the drive gear to rotate;

[0034] The drive gear drives the guide tube of drive component two to rotate. The spiral guide groove inside the guide tube cooperates with the guide wheel on the lifting shaft to convert the rotational motion into the linear lifting motion of the lifting shaft, thereby lifting the detection probe to a safe position and achieving avoidance during the cutting process.

[0035] In addition, when the cutting mechanism needs to pass through the servo electric cylinder stabilizer area of ​​the side fixing mechanism, the retraction mechanism works.

[0036] The electric shaft drives the horizontal plate and magnetic plate to move, bringing them close to the magnetic block on the control switch. Utilizing the principle of repulsion between like poles of magnetism, the magnetic force pushes the control switch, triggering the hydraulic system of the side fixing mechanism, causing the servo electric cylinder stabilizer to briefly release and perform a mechanical retraction action.

[0037] After the machine head and cutter head have passed through the area, the retraction mechanism resets, and the servo electric cylinder stabilizer of the side fixing mechanism immediately re-clamps the workpiece.

[0038] S4. Online inspection after cutting:

[0039] After the cutting is completed, the drive motor decelerates, the connecting shaft speed decreases, the rotor speed decreases accordingly, the centrifugal force of the centrifugal block decreases, the drive assembly one returns to its original state, the connecting arm two swings in the opposite direction, driving the toothed plate to move in the opposite direction, the toothed plate drives the drive gear to reverse, and thus causes the guide tube of the drive assembly two to rotate in the opposite direction.

[0040] Through the cooperation of the spiral guide groove and the guide wheel, the lifting shaft drives the detection probe to move downward; while the detection probe moves downward, the electric telescopic rod is controlled to push out the slide, so that the inclined seat on it moves to the predetermined position below the detection probe; the abutment part below the detection probe abuts against the inclined seat, forcing the abutment part in the abutment axis to contract inside the receiving cavity.

[0041] This action is driven by the first link to move the guide sleeve. The guide slope of the guide sleeve abuts against the elastic block, forcing the elastic block to move closer to the detection probe, and the clamping block reliably clamps and fixes the probe rod body.

[0042] Once the detection probe is clamped and fixed, its abutment prevents it from moving further downward due to its contact with the inclined seat. At this time, the lifting shaft continues to move downward under the action of the second drive assembly, pushing the fixed detection probe through the second linkage to produce a precise horizontal displacement towards the center of the cutter head. This action precisely sends the sensing part of the detection probe into the inside of the cutter head, and then controls the cutter head to rotate at a low speed, using the detection probe located inside it to perform online detection on the machined inner surface.

[0043] S5. Cleaning and Maintenance:

[0044] After machining and inspection, clean the chips and coolant, check the condition of key components such as the cutter head, servo electric cylinder stabilizer, and detection probe, and perform necessary maintenance to prepare for the next use.

[0045] In summary, this application includes at least one of the following beneficial technical effects:

[0046] 1. In this invention, the detection is performed by coordinating the rotation of the drive component with the spindle speed. When the speed reaches the target cutting state, the probe is raised to avoid the impact of chips, the scouring of coolant, and accidental contact damage through the combination of the centrifugal block, which greatly extends the life of the precision detection probe. When the speed decreases to the point where the cutting is completed, the centrifugal force weakens, the mechanism resets, and the probe automatically descends and extends for detection.

[0047] 2. During the detection process of this invention, the displacement is accurately positioned by the contacting of the contacting component and the contacting part. At the same time, the guide slope of the clamping component drives the clamping block to lock the detection mounting seat, eliminating the chatter during measurement and ensuring the repeatability and rigidity of the detection.

[0048] 3. During the cutting process of this invention, the high-speed rotation of the connecting shaft will cause high temperature to be generated in the transmission groove. At this time, the clutch seat in the clutch assembly rotates, thereby driving the impeller to provide forced air cooling for the drive motor. This makes the heat dissipation method closely linked with the transmission process. The heat dissipation is automatically started when the drive motor is working, without the need for an additional heat dissipation control device. This ensures the normal operation of the drive motor under long-term high-load operation and improves the overall energy utilization efficiency of the equipment.

[0049] 4. The unique structure of the clamping component in this invention allows operators to quickly and easily disassemble and install the detection probe. At the same time, the clamping component can calibrate the detection probe while clamping, greatly improving the availability and flexibility of the equipment.

[0050] 5. The retraction mechanism of this invention uses magnetic blocks with repulsive polarity to push the side fixing mechanism to retract. Compared with the traditional mechanical transmission method, the non-contact driving method reduces the direct contact and friction between components, thereby reducing mechanical wear, extending the service life of the equipment, and improving the retraction accuracy, so that the side fixing mechanism can retract accurately according to the preset requirements.

Detailed Implementation

[0064] The following is in conjunction with the appendix Figures 1-11 This application will be described in further detail.

[0065] Example 1, such as Figures 1-5As shown, this is the first embodiment of the present invention. This embodiment provides a precision forming internal cyclone cutting machine tool, including a machine base 1 and a cutting mechanism 2 disposed on the machine base 1. The cutting mechanism 2 includes an electric slide 21 slidably mounted on the machine base 1, a head 22 fixed to the upper surface of the electric slide 21, a cutter head 23 rotatably mounted on one side of the head 22, and a drive motor 25 mounted on the outer wall of the head 22. The drive motor 25 provides power for the entire cutting process. Specifically, a connecting shaft 25 for driving the cutter head 23 is fixed on the output shaft of the drive motor 25. 1. The machine head 22 has a transmission groove 221 and a sliding port 222 inside. The two sides of the transmission groove 221 are respectively connected to the outside of the two sides of the machine head 22. The connecting shaft 251 passes through the inside of the transmission groove 221. The end of the connecting shaft 251 away from the drive motor 25 and the outside of the cutter head 23 are both provided with transmission gears 26. The two transmission gears 26 mesh with each other. Through the meshing of the two transmission gears 26, the power of the drive motor 25 can be accurately transmitted to the cutter head 23, ensuring that the cutter head 23 rotates at the predetermined speed and direction, providing power guarantee for precise cutting.

[0066] In this embodiment, a hollow cover 24 is bolted to the outer wall of the machine head 22. The machine head 22, cover 24, and cutter head 23 all have vortex holes 27 communicating with the outside for workpiece insertion. These vortex holes 27 provide a reasonable channel for workpiece insertion, facilitating placement of the workpiece in a suitable position for cutting during processing. Additionally, the sliding port 222 needs to be sealed to prevent coolant ingress. The cutter head 23 needs to be equipped with a support function, such as an internal support mechanism as in the prior art, to automatically adjust the cutter on the cutter head 23, facilitating subsequent tool retraction.

[0067] To achieve precise forming, the machine base 1 in this embodiment is provided with a clamping part for fixing the workpiece, such as... Figure 2 and Figure 3 As shown, the clamping part includes two end fixing mechanisms 3 and multiple side fixing mechanisms 4 to achieve comprehensive fixation of the workpiece. The side fixing mechanism 4 includes a servo cylinder seat 41, a servo electric cylinder 42 bolted to the outside of the servo cylinder seat 41, and a servo electric cylinder stabilizer 43 fixed to the output end of the servo electric cylinder 42. Specifically, the two end fixing mechanisms 3 are distributed at the front and rear ends of the machine base 1, and the multiple side fixing mechanisms 4 are distributed in groups of three at equal intervals outside the machine base 1. The three side fixing mechanisms 4 are located on the left and right sides and the bottom side of the machine base 1, respectively, and work together with the two end fixing mechanisms 3 distributed at the front and rear to achieve comprehensive fixation of the workpiece, effectively preventing the workpiece from shaking or shifting during the cutting process, ensuring the cutting accuracy and stability, and thus achieving a precise forming effect.

[0068] It should be noted that the end fixing mechanism 3 and the side fixing mechanism 4 have the same principle and drive mechanism, but the fixing structure of the end fixing mechanism 3 is a pin, which can clamp and fix the end of the workpiece, while the servo electric cylinder stabilizer 43 on the side fixing mechanism 4 is adapted to the shape of the workpiece. Since the pin can accurately clamp and fix the end of the workpiece, and the servo electric cylinder stabilizer 43 on the side fixing mechanism 4 is adapted to the shape of the workpiece, the machine tool can adapt to the processing of workpieces of different shapes and sizes, thus improving the versatility and applicability of the machine tool.

[0069] To achieve automatic retraction between the end fixing mechanism 3 and the side fixing mechanism 4, a retraction mechanism 5 is fixed on the outer wall of the base 1 in this embodiment, and each set of side fixing mechanisms 4 is equipped with a control switch 44 for use with the retraction mechanism 5. For example... Figure 3 and Figure 4 As shown, the retraction mechanism 5 includes an electric shaft 51 fixed to the outer wall of the machine base 1, and the electric shaft 51 is a dual-axis configuration, which can be a dual-axis electric cylinder. Each of the two output shafts of the electric shaft 51 has a horizontal plate 52 fixed to it, and a magnetic plate 53 is fixed to one side of each horizontal plate 52. A magnetic block with repulsive poles is fixed between the magnetic plate 53 and the control switch 44. It should be noted that the length of the magnetic plate 53 is adapted to the horizontal plate 52, and the length of the horizontal plate 52 is longer than the electric slide table 21. This avoids the end fixing mechanism 3 and the side fixing mechanism 4 only activating after the electric slide table 21 has passed. This achieves the automatic retraction function of the end fixing mechanism 3 and the side fixing mechanism 4. During processing, when space needs to be cleared, the retraction mechanism 5 can move automatically without manual operation, greatly improving processing efficiency and reducing time loss and errors caused by manual operation.

[0070] Furthermore, all three side-fixing mechanisms 4 in each group use the same controller; and the servo electric cylinders 42 are connected to the machine tool's central numerical control system (CNC) or programmable logic controller (PLC) via multi-core shielded cables. These cables integrate power supply, servo drive signals, enable signals, alarm feedback, and high-precision position feedback signals from their built-in encoders. The PLC or CNC, according to the program settings, simultaneously sends control commands to the drivers of all relevant servo electric cylinders 42. The commands include the target position and the set clamping force. Upon receiving the command, each servo electric cylinder 42 starts its internal servo motor, driving the push rod to extend. The device's high-resolution encoder monitors the push rod position in real time and feeds the signal back to the driver, forming a fully closed-loop position control system to ensure that each stabilizer 43 can move precisely to the predetermined position. After all servo electric cylinders 42 reach the predetermined position and achieve the set force, they send a clamping confirmation signal to the PLC or CNC. Only after receiving all confirmation signals does the machine tool's safety interlock allow the spindle to start and cutting to begin, ensuring absolute safety.

[0071] After processing is completed, the program issues a release command. At this time, the electric shaft 51 of the retraction mechanism 5 moves first, driving the magnetic plate 53 on it to move. The magnetic plate 53 and the same pole magnetic block on the side fixing mechanism 4 generate a repulsive force. This repulsive force serves as a trigger signal. The controlled switch 44 can be a high-sensitivity magnetic proximity switch or a pressure sensor. The switch 44 transmits the signal to the PLC, and the PLC then commands the corresponding servo electric cylinder 42 to retract, realizing automatic and orderly retraction. The length design of the horizontal plate 52 ensures that the retraction action is completed before the electric slide 21 arrives, perfectly realizing the automated timing switch between the processing space and the clamping space.

[0072] Therefore, the design using like-pole repulsion magnetic blocks is ingenious. When the retraction mechanism 5 is activated, the electric shaft 51 drives the horizontal plate 52 and the magnetic plate 53 to move. The repulsive force between the magnetic plate 53 and the magnetic block will act precisely on the side fixing mechanism 4, pushing it to retract. Moreover, this non-contact driving method reduces direct contact and friction between parts compared to the traditional mechanical transmission method, thereby reducing mechanical wear, extending the service life of the equipment, and improving the retraction accuracy, so that the side fixing mechanism 4 can retract accurately according to the preset requirements.

[0073] Furthermore, since the length of the horizontal plate 52 is longer than that of the electric slide table 21, if the retraction mechanism 5 is activated too late during the movement of the electric slide table 21, interference may occur between the electric slide table 21 and the clamping part, affecting the normal processing. However, the length of the horizontal plate 52 ensures that the retraction mechanism 5 is activated before the electric slide table 21 reaches the corresponding position, allowing the end fixing mechanism 3 and the side fixing mechanism 4 to retract in time, providing sufficient space for the movement of the electric slide table 21 and ensuring the smooth progress of the entire processing.

[0074] Example 2, as follows Figure 1 , Figures 5-11 As shown, this is the second embodiment of the present invention. Unlike the first embodiment, this embodiment specifically addresses the internal monitoring challenges during the machining process. Therefore, a detection component 6 is provided on the outside of the tool head 23. The detection component 6 includes a detection mounting base 61 and a detection probe 62 that is plugged into and installed inside the detection mounting base 61. It should be noted that the detection probe 62 is a high-precision, high-protection-level machine tool in-machine measurement probe. It preferably adopts a wireless signal transmission method such as infrared or radio, and has multi-directional triggering function and micron-level repeatability measurement accuracy. Its specific model can be selected according to the actual measurement accuracy requirements, CNC system compatibility, and installation interface.

[0075] In this embodiment, the machine head 22 is equipped with a drive mechanism for adjusting the position of the detection probe 62. The drive mechanism includes a drive component 7 and a drive component 8. The drive component 7 is linked with the drive motor 25 and the drive component 8 is used to realize the displacement of the detection component 6. The detection component 6 also includes a contact part that is raised and lowered with the drive component 8, so that the detection component 6 can be moved in the X-axis direction. It should be noted that since the cutter head 23 and its cutting area are located inside the machine head 22, a protective shell or cover 24 is usually provided on the outside to ensure safety and prevent chip splashing. This closed structure makes it difficult for the operator to directly observe the real-time working status and wear of the tool on the cutter head 23 and the instantaneous shape of the workpiece during processing. Under the control of the drive mechanism, the detection probe 62 can automatically and accurately move to a key position inside the cutter head 23 during the cutting interval or after the cutting is completed, and directly or indirectly detect the wear condition of the tool and the state of the cutting edge.

[0076] In addition, the detection component 6 is located above the workpiece. Besides the tool status, it can also perform real-time or near-real-time detection of relevant key parameters during the machining process. For example, it can scan the machined surface to provide feedback on dimensional accuracy, roundness, surface roughness, and other information. By timely and automatically acquiring these key information that are difficult to observe under traditional closed structures, the system or operators can make quick judgments and adjustments. For example, it can provide early warning and stop the machine to replace the tool when excessive tool wear or damage is detected; and it can compensate for machining parameters in a timely manner when dimensional trend deviations are found, avoiding the risk of batch product non-conformity due to the concealment of internal tools or the difficulty in detecting dimensional drift.

[0077] like Figure 7 As shown, the abutment in this embodiment includes an abutment shaft 66, with a ball bearing 67 rotatably mounted at the bottom end of the abutment shaft 66. When the abutment contacts and moves relative to components such as the drive assembly 2 8, it can convert sliding friction into rolling friction. The frictional force of rolling friction is much smaller than that of sliding friction, greatly reducing energy loss during movement. This allows the abutment to move more smoothly under the action of the drive assembly 2 8, thereby driving the detection assembly 6 to move flexibly and accurately in the X-axis direction, improving the efficiency and accuracy of the position adjustment of the detection assembly 6. Specifically, the detection mounting base 6 The device has an internal cavity 68. A return spring 69 extending into the cavity 68 is fixed to the top of the abutment shaft 66. When the abutment moves downward under the action of the drive assembly 8, the return spring 69 is compressed. When the drive assembly 8 stops applying force or the applied force decreases, the elastic restoring force of the return spring 69 will cause the abutment shaft 66 to automatically return upward. The automatic reset function enables the detection assembly 6 to quickly return to the initial position or preset position after completing one position adjustment, preparing for the next detection and improving the continuity and efficiency of the detection work.

[0078] Specifically, a connecting block 63 is fixed to the top side of the detection mounting base 61, and a mounting sleeve 64 is provided on one side of the connecting block 63, which is sleeved on the outside of the drive assembly 8. A guide rod 65 is elastically installed between the connecting block 63 and the mounting sleeve 64. The guide rod 65 can limit the shaking and displacement of the detection assembly 6 during the movement, ensuring that the detection assembly 6 always moves along the predetermined direction, improving the stability and accuracy of the position adjustment of the detection assembly 6, and ensuring the normal operation of the detection work.

[0079] like Figure 6 and Figure 8 As shown, the drive assembly 7 in this embodiment includes a clutch seat 71, a rotor 72 disposed inside the clutch seat 71 and fixed to the outer surface of the connecting shaft 251, a sleeve 73 disposed outside the rotor 72, and a centrifugal block 74. The sleeve 73 is sleeved on the outer surface of the connecting shaft 251, the centrifugal block 74 is slidably connected to the rotor 72, and a connecting arm 75 is installed between the centrifugal block 74 and the sleeve 73. An impeller 76 for heat dissipation of the drive motor 25 is also fixed on the clutch seat 71, and a connecting arm 77 of the drive assembly 8 is disposed outside the sleeve 73. The clutch seat 71 is rotatably mounted inside the transmission groove 221. The centrifugal block 74 in the drive assembly 7 generates centrifugal displacement through the rotation of the rotor 72 and abuts against the clutch seat 71, causing the clutch seat 71 to rotate. The connecting arm 77 extends through the sliding port 222 and into the cover 24. The end of the connecting arm 77 is fixed with a toothed plate 78. The outside of the toothed plate 78 is engaged with a drive gear 79 fixed to the drive assembly 8.

[0080] It should be noted that in the drive assembly 7, a buffer spring is provided between the centrifugal block 74 and the rotor 72, and the number of centrifugal blocks 74 and connecting arms 75 is at least two; there are two sleeves 73, and the two sleeves 73 are rotatably connected, one of which is sleeved with the outer surface of the connecting shaft 251. To facilitate transmission, an anti-slip pad that abuts against the clutch seat 71 is fixed on the outside of the centrifugal block 74; in this embodiment, when the drive motor 25 is running at high speed, it drives the connecting shaft 251 and the rotor 72 fixed on it to rotate at high speed. At this time, the centrifugal block 74 overcomes the elastic force of the buffer spring under the action of centrifugal force and slides outward along the rotor 72. Through the pushing of the connecting arm 75, this sliding is converted into an axial or radial force on the sleeve 73, which ultimately forces the outer friction surface of the centrifugal block 74 to press against the inner wall of the stationary or low-speed clutch seat 71, generating a strong frictional force to drive the clutch seat 71 to rotate. The impeller 76 fixed on it rotates synchronously, generating a directional airflow to provide forced air cooling for the drive motor 25 under high speed and high load conditions. This effectively utilizes the waste energy during cutting, improves the heat dissipation efficiency and continuous working capacity of the motor, and has a compact and efficient structure.

[0081] Simultaneously, the sleeve 73 and the connecting arm 77 fixed thereon also swing. The swing of the connecting arm 77 pushes the toothed plate 78 fixed thereon to move in a straight line. The toothed plate 78 then drives the drive gear 79 meshing with it to rotate. The rotation of the drive gear 79 is directly input to the drive assembly 8. Finally, through components such as the lifting shaft 83, the detection probe 62 is raised to a safe height, automatically avoiding interference and damage to the detection probe during the cutting process.

[0082] like Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, the drive assembly 8 in this embodiment includes a hollow guide cylinder 81 and a guide tube 82. A lifting shaft 83 is provided inside the guide tube 82. The bottom end of the lifting shaft 83 extends into the inside of the cover 24, and a second connecting rod 87 is hinged between the bottom end of the lifting shaft 83 and the outer wall of the detection mounting base 61. It should be noted that the drive gear 79 is fixed to the outer surface of the guide tube 82. The guide tube 82 has a spiral guide groove 84 inside, which is arranged around its outer surface. The length of the spiral guide groove 84 is adapted to the lifting height of the lifting shaft 83. The guide cylinder 81 is usually made of high-strength and wear-resistant material to withstand the friction and external forces generated by the guide tube 82 during movement. Furthermore, the outer surface of the lifting shaft 83 is rotatably mounted with a guide wheel 85 that rolls with the spiral guide groove 84. The outer surface of the lifting shaft 83 is also provided with a limiting groove 86 for limiting. The guide cylinder 81 is equipped with a guide key that slides with the limiting groove 86, thereby limiting the direction and range of movement of the lifting shaft 83. This can prevent the lifting shaft 83 from rotating or moving excessively during movement, ensuring that the lifting shaft 83 always moves along a predetermined straight line, thus improving the accuracy and stability of the position adjustment of the detection mounting base 61.

[0083] In this embodiment, when the lifting shaft 83 drives the detection probe 62 to descend and the probe is locked by the clamping component 10, the lower end of the probe stops displacing due to contact with the inclined seat 93. At this time, if the lifting shaft 83 continues to descend under the action of the driving component 8, the second connecting rod 87 between it and the detection mounting base 61 will generate a thrust, pushing the clamped detection mounting base 61 and the probe 62 together to generate a precise linear displacement in the horizontal direction, that is, in the X-axis direction pointing to the center of the cutter head 23, thereby sending the probe of the detection probe 62 into the detection position inside the cutter head 23.

[0084] To ensure stable detection by the detection probe 62, in this embodiment, the detection mounting base 61 is further provided with a clamping component 10 and abutment component 9 for use with the abutment member; such as Figure 11As shown, the contact assembly 9 includes an electric telescopic rod 91, a slide 92 fixed to the output end of the electric telescopic rod 91, and an inclined seat 93 fixed to the top side of the slide 92. The electric telescopic rod 91 is fixed to the outer wall of the cover 24. In use, the ball bearing 67 engages with the inclined seat 93. Due to the inclined surface of the inclined seat 93, the probe stops moving after the ball bearing 67 reaches the bottom of the inclined surface. However, the lifting shaft 83 continues to descend under the drive of the second drive assembly 8. Since the probe is held tightly and the displacement is blocked, the downward force of the lifting shaft 83 is converted into a force that pushes the probe's X-axis movement through the geometric relationship of the second link 87, smoothly and accurately sending it into the cutter head 23. Furthermore, the inclined surface of the inclined seat 93 can extend or shorten the contact distance of the contacting parts, thereby allowing the detection probe 62 to better adapt to the detection of the cutter head 23.

[0085] To facilitate the installation and removal of the detection probe 62, such as Figure 7 and Figure 10 As shown, the clamping assembly 10 includes a limiting sleeve 1001 and a guide sleeve 1005, both of which are hollow inside. The guide sleeve 1005 is slidably connected to the limiting sleeve 1001. An elastic block 1002 is fixed to the outer wall of the detection mounting base 61 inside the limiting sleeve 1001. A clamping block 1004 is snapped onto the inner side of the elastic block 1002. The inner side of the guide sleeve 1005 and the outer wall of the elastic block 1002 are provided with a guide inclined surface 1003 that abuts against each other. The guide inclined surface 1003 is a matching cone shape. When the guide sleeve 1005 slides axially, the cone surface forces the elastic block 1002 to contract radially inward, causing the clamping block 1004 to clamp the detection probe 62. A first connecting rod 610 is hinged between the guide sleeve 1005 and the abutment shaft 66.

[0086] It should be noted that there are at least two elastic blocks 1002; the elastic blocks 1002 are made of high-performance engineering elastic materials, preferably polyurethane elastomers with high elastic modulus, high wear resistance and good oil resistance, and the inner side of the clamping block 1004 is fixed with a protective pad; the clamping component 10 greatly improves the convenience of disassembling and assembling the detection probe 62. In application scenarios, the detection probe 62 may need to be frequently disassembled and assembled due to regular maintenance, replacement, repair or model change according to different detection needs. The unique structure of this clamping component 10 allows operators to quickly and easily disassemble and install the detection probe 62. At the same time, when the clamping component 10 clamps, it can calibrate the detection probe 62, which greatly improves the availability and flexibility of the equipment.

[0087] Example 3: Another problem that the present invention needs to solve is to provide a method for using a precision-forming internal cyclone cutting machine tool, including the following steps:

[0088] S1. Preparations:

[0089] First, confirm that all parts of the machine tool are in good condition and adequately lubricated. Pay special attention to checking the conveying equipment, end fixing mechanism 3, side fixing mechanism 4, cutting mechanism 2 cutter head 23, retraction mechanism 5, drive motor 25, and cooling and detection system.

[0090] The workpiece to be processed is then smoothly conveyed to the designated processing position on the machine base 1 via the tail conveyor.

[0091] Next, install and calibrate the tool head 23, and confirm that the CNC program or machining parameters are set correctly;

[0092] S2. Workpiece fixing:

[0093] Activate end fixing mechanism 3 to firmly clamp one end of the workpiece;

[0094] Then the side fixing mechanism 4 is activated, and its servo electric cylinder stabilizer 43 applies clamping force from the side of the workpiece to achieve all-round rigid fixing.

[0095] S3. Cutting and Coordination Motions:

[0096] First, start the drive motor 25, which drives the cutter head 23 to rotate at high speed through the connecting shaft 251 and the transmission gear 26;

[0097] Then start the electric slide table 21, which drives the head 22 and the cutter head 23 to feed along the workpiece axis for internal cyclone cutting;

[0098] During cutting, the connecting shaft 251 rotates at high speed, driving the rotor 72 outside it to rotate synchronously; the centrifugal block 74 on the rotor 72 slides outward under the action of centrifugal force, and pushes the sleeve 73 through the connecting arm 75, eventually causing the centrifugal block 74 to press against the inner wall of the clutch seat 71 to generate friction, thereby driving the clutch seat 71 to rotate.

[0099] The clutch seat 71 drives the impeller 76 to rotate, providing forced air cooling for the drive motor 25;

[0100] At the same time, the connecting arm 77 swings, pushing the meshing toothed plate 78 to move in a straight line, and the toothed plate 78 drives the drive gear 79 to rotate.

[0101] The drive gear 79 drives the guide tube 82 of the drive assembly 8 to rotate. The spiral guide groove 84 inside the guide tube 82 cooperates with the guide wheel 85 on the lifting shaft 83 to convert the rotational motion into the linear lifting motion of the lifting shaft 83, thereby lifting the detection probe 62 to a safe position and achieving avoidance during the cutting process.

[0102] In addition, when the cutting mechanism 2 needs to pass through the area of ​​the servo electric cylinder stabilizer 43 of the side fixing mechanism 4, the retraction mechanism 5 works.

[0103] The electric shaft 51 drives the horizontal plate 52 and the magnetic plate 53 to move closer to the magnetic block on the control switch 44. Utilizing the principle of repulsion between like poles of magnetism, the magnetic force pushes the control switch 44, triggering the hydraulic system of the side fixing mechanism 4, causing the servo electric cylinder stabilizer 43 to briefly release and perform a mechanical retraction action.

[0104] After the machine head 22 and the cutter head 23 pass through the area, the retraction mechanism 5 resets, and the servo electric cylinder stabilizer 43 of the side fixing mechanism 4 immediately re-clamps the workpiece.

[0105] S4. Online inspection after cutting:

[0106] After the cutting is completed, the drive motor 25 decelerates, the connecting shaft 251 speed decreases, the rotor 72 speed decreases accordingly, the centrifugal force of the centrifugal block 74 decreases, the drive assembly 1 7 returns to its original state, the connecting arm 2 77 swings in the opposite direction, driving the toothed plate 78 to move in the opposite direction, the toothed plate 78 drives the drive gear 79 to reverse, thereby causing the guide tube 82 of the drive assembly 2 8 to rotate in the opposite direction.

[0107] Through the cooperation of the spiral guide groove 84 and the guide wheel 85, the lifting shaft 83 drives the detection probe 62 to move downward; while the detection probe 62 moves downward, the electric telescopic rod 91 is controlled to push out the slide 92, so that the inclined seat 93 on it moves to the predetermined position below the detection probe 62; the abutment below the detection probe 62 abuts against the inclined seat 93, forcing the abutment shaft 66 in the abutment to retract into the receiving cavity 68;

[0108] This action drives the guide sleeve 1005 to move through the first connecting rod 610. The guide slope 1003 of the guide sleeve 1005 abuts against the elastic block 1002, forcing the elastic block 1002 to move closer to the detection probe 62, and the clamping block 1004 reliably clamps and fixes the rod of the detection probe 62.

[0109] After the detection probe 62 is clamped and fixed, its abutment is stopped from moving further down by abutting against the inclined seat 93. At this time, the lifting shaft 83 continues to move downward under the action of the second drive assembly 8, and pushes the fixed detection probe 62 through the second connecting rod 87, so that it produces a precise horizontal displacement towards the center of the cutter head 23. This action precisely sends the sensing part of the detection probe 62 into the inside of the cutter head 23, and then controls the cutter head 23 to rotate at a low speed, using the detection probe 62 located inside it to perform online detection on the machined inner surface;

[0110] S5. Cleaning and Maintenance:

[0111] After machining and inspection, clean up chips and coolant, check the condition of key components such as the cutter head 23, servo cylinder stabilizer 43, and detection probe 62, and perform necessary maintenance to prepare for the next use.

[0112] Combined with appendix Figures 1-11 The working principle of the above embodiments is as follows:

[0113] In use, the workpiece is first conveyed to the machine base 1 by the conveying equipment at the tail of the bed, and then fixed in all directions by the end fixing mechanism 3 and the side fixing mechanism 4 respectively. Then, the cutter head 23 is rotated by the drive motor 25, the connecting shaft 251 and the transmission gear 26 to perform internal cyclone cutting. When the cutter head 23 is working, it moves linearly by the electric slide table 21, thereby driving the machine head 22 to move along the workpiece. When the cutting mechanism 2 needs to pass through the area of ​​the servo electric cylinder stabilizer 43, the retraction mechanism 5 works, the electric shaft 51 drives the horizontal plate 52 and the magnetic plate 53 to move, so that they are close to the magnetic block on the control switch 44. Due to the repulsion of like poles, the magnetic force pushes the control switch 44, triggering the hydraulic system of the side fixing mechanism 4, so that the servo electric cylinder stabilizer 43 is briefly loosened and retracted, and then re-clamped after the machine head 22 passes through.

[0114] In addition, during cutting, the connecting shaft 251 drives the transmission. At this time, the centrifugal block 74 on the rotor 72 outside it slides outward under the action of centrifugal force. Through the connecting arm 1 75, the sleeve 73 is pushed, and finally the centrifugal block 74 is pressed against the inner wall of the rotating clutch seat 71, generating friction and driving the clutch seat 71 to start rotating. The rotation of the clutch seat 71 drives the impeller 76 fixed on it to rotate synchronously, which forces the drive motor 25 to be cooled by air. At the same time, the connecting arm 2 77 swings accordingly, pushing the toothed plate 78 that meshes with it to make linear motion. The toothed plate 78 drives the drive gear 79 to rotate, and the drive gear 79 drives the guide tube 82 of the drive assembly 2 8 to rotate, lifting the detection probe 62 and realizing the yielding effect.

[0115] After the cutting is completed, the rotational speed of the connecting shaft 251 decreases. At this time, the rotational speed of the rotor 72 decreases and the drive assembly 7 returns to its original state. The toothed plate 78 drives the drive gear 79 to rotate, and the drive gear 79 drives the guide tube 82 of the drive assembly 8 to rotate. The spiral guide groove 84 in the guide tube 82 cooperates with the guide wheel 85 on the lifting shaft 83 to convert the rotational motion of the guide tube 82 into the linear lifting motion of the lifting shaft 83. At this time, the lifting shaft 83 drives the detection probe 62 to move down. At the same time, the slide 92 is pushed out through the electric telescopic rod 91. The abutment below the detection probe 62 abuts against the inclined seat 93. The abutment shaft 66 in the abutment extends into the receiving cavity 68. At the same time, the first connecting rod 610 and the second connecting rod 87 work respectively.

[0116] First, the first connecting rod 610 drives the outside of the guide sleeve 1005, and the elastic block 1002 moves closer to the detection probe 62 by the abutment of the guide inclined surface 1003, and the detection probe 62 is fixed by the clamping block 1004.

[0117] Since the contact part of the detection probe 62 is abutting against the slide 92 and no longer moves, the lifting shaft 83 will continue to move and push the detection probe 62 through the second connecting rod 87, so that the detection probe 62 can move forward and in the X-axis direction, and move the detection probe 62 into the cutter head 23. By rotating the bottom of the cutter head 23, the detection probe 62 is used for detection.

[0118] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.

Cutting and Coordination Motions: First, start the drive motor (25), which drives the cutter head (23) to rotate at high speed through the connecting shaft (251) and the transmission gear (26); Then start the electric slide (21) to drive the head (22) and cutter head (23) to feed along the workpiece axis and perform internal cyclone cutting; During cutting, the connecting shaft (251) rotates at high speed, driving the rotor (72) outside it to rotate synchronously; the centrifugal block (74) on the rotor (72) slides outward under the action of centrifugal force, and pushes the sleeve (73) through the connecting arm (75), so that the centrifugal block (74) presses against the inner wall of the clutch seat (71) to generate friction, thereby driving the clutch seat (71) to rotate; The clutch seat (71) drives the impeller (76) to rotate, providing forced air cooling for the drive motor (25); At the same time, connecting arm two (77) swings, pushing the meshing toothed plate (78) to move in a straight line, and the toothed plate (78) drives the drive gear (79) to rotate; The drive gear (79) drives the guide tube (82) of the drive assembly (8) to rotate. The spiral guide groove (84) inside the guide tube (82) cooperates with the guide wheel (85) on the lifting shaft (83) to convert the rotational motion into the linear lifting motion of the lifting shaft (83), thereby lifting the detection probe (62) to a safe position and achieving avoidance during the cutting process. In addition, when the cutting mechanism (2) needs to pass through the area of ​​the servo electric cylinder stabilizer (43) of the side fixing mechanism (4), the retraction mechanism (5) works; The electric shaft (51) drives the horizontal plate (52) and the magnetic plate (53) to move, bringing them close to the magnetic block on the control switch (44). Utilizing the principle of repulsion between like poles of magnetism, the magnetic force pushes the control switch (44), triggering the hydraulic system of the side fixing mechanism (4), causing the servo electric cylinder stabilizer (43) to briefly release and perform a mechanical retraction action.

Online inspection after cutting: After the cutting is completed, the drive motor (25) decelerates, the connecting shaft (251) speed decreases, the rotor (72) speed decreases accordingly, the centrifugal force of the centrifugal block (74) decreases, the drive assembly one (7) returns to its original state, the connecting arm two (77) swings in the opposite direction, driving the toothed plate (78) to move in the opposite direction, the toothed plate (78) drives the drive gear (79) to reverse, thereby causing the guide tube (82) of the drive assembly two (8) to rotate in the opposite direction; Through the cooperation of the spiral guide groove (84) and the guide wheel (85), the lifting shaft (83) drives the detection probe (62) to move downward; while the detection probe (62) moves downward, the electric telescopic rod (91) is controlled to push out the slide (92), so that the inclined seat (93) on it moves to the predetermined position below the detection probe (62); the abutment below the detection probe (62) abuts against the inclined seat (93), forcing the abutment shaft (66) in the abutment to retract into the receiving cavity (68); This action drives the guide sleeve (1005) to move through the first link (610).

When the detection probe (62) is clamped and fixed, its abutment is stopped from moving further down because it abuts against the inclined seat (93). At this time, the lifting shaft (83) continues to move downward under the action of the second drive assembly (8), and pushes the fixed detection probe (62) through the second connecting rod (87) to make it produce a precise horizontal displacement towards the center of the cutter head (23). This action precisely sends the sensing part of the detection probe (62) into the inside of the cutter head (23), and then controls the cutter head (23) to rotate at a low speed, and uses the detection probe (62) located inside it to perform online detection on the machined inner surface; S5. Cleaning and Maintenance: After the machining and inspection are completed, clean up the chips and coolant, check the condition of key components such as the cutter head (23), servo electric cylinder stabilizer (43), and detection probe (62), and perform necessary maintenance to prepare for the next use.
