Description

Technical Field

[0001] The present application relates to the field of mechanical processing technology, and specifically to a CNC machine tool for flange processing. Background Art

[0002] Flanges, also known as flanged discs or flanges, are components that connect shafts and pipe ends. They are also used on equipment inlets and outlets, such as reducer flanges, to connect two pieces of equipment. Flange production is primarily categorized into four types: casting, forging, cutting, and rolling. Forged flanges are less prone to rust, offer streamlined shapes, are tightly packed, and offer superior mechanical properties.

[0003] In the prior art, after forging, forged flanges are typically transported to drilling, turning, and milling stations for finishing processes such as drilling, turning, and milling. However, these processes cannot be completed in the same operating area, resulting in long processing lines, high labor requirements, and low production efficiency. Furthermore, each of these processes requires the flange to be re-clamped and re-positioned, and turning requires two re-clamping and re-positioning steps, which increases the workload and reduces efficiency.

[0004] Therefore, how to design a CNC machine tool for flange processing to overcome the above-mentioned shortcomings is a problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0015] Preferably, the power supply further includes a protective cover, which is detachably arranged at the upper end of the mounting hole, and a wire hole is penetrated through the protective cover.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] (1) Since the support seat on the left side can rotate horizontally on the frame on the left side, when one end of the support seat on the left side is rotated to face the loading station, the flange to be processed is clamped to the corresponding one of the clamping mechanisms to complete the loading operation; similarly, the flange to be processed can be clamped on both of the clamping mechanisms on the left side to improve the efficiency of production and processing.

[0018] (2) Since the connecting line between the turning mechanism and the drilling mechanism passes through the rotation axis of the support seat on the left, after the loading operation is completed, the support seat on the left is controlled to rotate clockwise until the two ends of the support seat face the drilling mechanism and the turning mechanism respectively. The drilling mechanism is used to drill the corresponding flange to form a bolt hole. Correspondingly, the turning mechanism is used to perform the first turning process on the corresponding other flange, that is, turning one end face, half of the outer ring surface and the inner ring surface of the flange. At the same time, since the support seat on the left rotates clockwise, the flange is first drilled and then turned, that is, one end of the bolt hole can be chamfered at the same time during the turning process. In other words, the drilling process and the first turning process are performed simultaneously, further improving the efficiency of production and processing.

[0019] (3) When the flange clamped on the left clamping mechanism completes the drilling process and the first turning process in sequence, continue to control the left support seat to rotate clockwise, and at the same time, the right support seat rotates clockwise until one of the clamping mechanisms at one end of the right support seat is aligned with one of the clamping mechanisms on the left. The right clamping mechanism slides to the left until the flange on the left clamping mechanism is clamped. Then, the left clamping mechanism releases the flange. At this time, the flange on the left clamping mechanism is transferred to the right clamping mechanism, and the unprocessed end face of the flange is just facing the outside of the corresponding clamping mechanism. After clamping the flange, the right clamping mechanism slides to the right first, so that the flange is completely separated from the left clamping mechanism. Similarly, the flange after the drilling process and the first turning process can be clamped on both the right clamping mechanisms. After the transfer, the flange clamped on the left clamping mechanism can continue to return to the loading station for re-clamping. That is to say, after the first turning process, the flange can be automatically transferred and its direction can be adjusted without manual re-clamping and re-positioning of the flange.

[0020] (4) Since the connecting line between the turning mechanism and the milling mechanism passes through the rotation axis of the support seat on the right side, when the flange is transferred to the clamping mechanism on the right side, the support seat on the right side is controlled to rotate clockwise until the two ends of the support seat on the right side face the turning mechanism and the milling mechanism respectively, the turning mechanism is able to perform a second turning process on the corresponding one of the flanges, that is, turning the unprocessed end face of the flange, the other half of the outer ring surface, and the chamfer of the other end of the bolt hole; at the same time, the milling mechanism is able to perform a milling process on the corresponding other flange, thereby forming an internal spline. In other words, the second turning process and the milling process are carried out simultaneously, further improving the efficiency of production and processing; and since the support seat on the right side also rotates clockwise, before the milling process is performed, the inner ring surface of the flange can be turned and chamfered by the first turning process (or the second turning process), thereby providing the necessary processing foundation for milling the internal spline.

[0021] (5) After the flange has been milled, continue to control the support seat on the right to rotate clockwise until the corresponding clamping mechanism faces the blanking station, and then remove the flange to complete the blanking operation; after removing the flange, the corresponding clamping mechanism can continue to rotate clockwise with the support seat on the right, so as to re-clamp the flange on the clamping mechanism on the left.

[0022] (6) From the above content, it can be seen that when the loading station and the unloading station are set in the same operating area, that is, the loading station and the unloading station are both located between the drilling mechanism and the milling mechanism, and are located directly in front of the turning mechanism; then when the loading operation is performed, one end of the support seat on the left side faces the operating area so as to perform a loading operation, and the two ends of the support seat on the right side just face the turning mechanism and the milling mechanism, so as to perform the second turning process on one flange and the milling process on one flange at the same time of loading; then when the unloading operation is performed, one end of the support seat on the right side faces the operating area so as to perform a unloading operation, and the two ends of the support seat on the left side just face the drilling mechanism and the turning mechanism, so as to perform the drilling process on one flange and the first turning process on one flange at the same time of unloading. In other words, this processing method can greatly improve production efficiency. In addition, the loading station and the unloading station can be placed in the same operating area, and the loading and unloading operations can be staggered, so that only one operator is needed to complete all operations, thereby reducing the demand for labor. During the entire processing process, for the same flange, the operator only needs to complete one clamping and positioning operation and one removal operation, which reduces the manual workload and improves work efficiency. In addition, since the turning mechanism can be horizontally rotatably arranged behind the two support seats, when performing the loading operation, the turning mechanism rotates counterclockwise to the clamping mechanism on the support seat facing the right, thereby performing a second turning process on the corresponding flange; when performing the unloading operation, the turning mechanism rotates clockwise to the clamping mechanism on the support seat facing the left, thereby performing a first turning process on the corresponding flange. In other words, the CNC machine tool only needs to be equipped with one turning mechanism, and the equipment cost is lower. BRIEF DESCRIPTION OF THE DRAWINGS

The terms "including" and "having" in the description and claims of the present application and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or inherent to these processes, methods, products or devices.

[0045] Reference Figures 1 to 5 , an embodiment of the present application provides a CNC machine tool for processing a flange 300, comprising a drilling mechanism 1, a turning mechanism 2, a milling mechanism 3, two frames 4, two support seats 5 and four clamping mechanisms 6 for clamping the flange 300; the two frames 4 are arranged at intervals on the left and the right, and the two support seats 5 can be horizontally rotatably arranged on the two frames 4 respectively; the two clamping mechanisms 6 are respectively arranged at the two ends of the left support seat 5, and the distances between the two clamping mechanisms 6 and the rotation axis of the support seat 5 are equal; the other two clamping mechanisms 6 can be horizontally slidably arranged at the two ends of the right support seat 5, and the sliding directions of the two clamping mechanisms 6 are parallel to each other; the drilling mechanism 1 is arranged at the left front of the left support seat 5, and the milling mechanism 3 is arranged at the right front of the right support seat 5; the turning mechanism 2 is horizontally rotatably arranged behind the two support seats 5, the connecting line between the turning mechanism 2 and the drilling mechanism 1 passes through the rotation axis of the left support seat 5, and the connecting line between the turning mechanism 2 and the milling mechanism 3 passes through the rotation axis of the right support seat 5.

[0046] like Figure 2 As shown, since the support seat 5 on the left can rotate horizontally on the frame 4 on the left, when one end of the support seat 5 on the left is rotated to face the loading station, the flange 300 to be processed is clamped to a corresponding clamping mechanism 6 to complete the loading operation; similarly, the flange 300 to be processed can be clamped on both clamping mechanisms 6 on the left to improve the efficiency of production and processing.

[0047] like Figure 3As shown, since the connection line between the turning mechanism 2 and the drilling mechanism 1 passes through the rotation axis of the left support seat 5, after the loading operation is completed, the left support seat 5 is controlled to rotate clockwise until the two ends of the support seat 5 face the drilling mechanism 1 and the turning mechanism 2 respectively, and the drilling mechanism 1 is used to drill a corresponding flange 300, thereby forming a bolt hole 301 (as shown in FIG. Figure 19 (as shown); correspondingly, the turning mechanism 2 is used to perform the first turning operation on the corresponding flange 300, namely, turning one end face, half of the outer annular surface, and the inner annular surface of the flange 300. Moreover, because the left support seat 5 rotates clockwise, the flange 300 is first drilled and then subjected to the first turning operation, thereby simultaneously chamfering one end of the bolt hole 301. In other words, the drilling operation and the first turning operation are performed simultaneously, further improving production efficiency.

[0048] like Figure 4 As shown, after the flange 300 clamped on the left clamping mechanism 6 completes the drilling process and the first turning process in sequence, the left support seat 5 continues to be controlled to rotate clockwise, and at the same time, the right support seat 5 rotates clockwise until a clamping mechanism 6 at one end of the right support seat 5 is aligned with a clamping mechanism 6 on the left, the right clamping mechanism 6 slides to the left until the flange 300 on the left clamping mechanism 6 is clamped, and the left clamping mechanism 6 releases the flange 300. At this time, the flange 300 on the left clamping mechanism 6 is transferred to the right clamping mechanism 6, and the unprocessed end face of the flange 300 is just facing the outside of the corresponding clamping mechanism 6. After the right clamping mechanism 6 clamps the flange 300, it slides to the right first, so that the flange 300 is completely separated from the left clamping mechanism 6; similarly, the flange 300 that has been drilled and the first turning process can be clamped on both clamping mechanisms 6 on the right. After the flange 300 is transferred and clamped on the left clamping mechanism 6, it can continue to return to the loading station for re-clamping. In other words, after the first turning process, the flange 300 can be automatically transferred and adjusted in direction, without the need for manual re-clamping and positioning of the flange 300.

[0049] like Figure 3As shown, since the connection line between the turning mechanism 2 and the milling mechanism 3 passes through the rotation axis of the right support seat 5, when the flange 300 is transferred to the right clamping mechanism 6, the right support seat 5 is controlled to rotate clockwise until the two ends of the right support seat 5 face the turning mechanism 2 and the milling mechanism 3 respectively, the turning mechanism 2 is able to perform a second turning process on the corresponding flange 300, that is, turning the unprocessed end face of the flange 300, the other half of the outer ring surface, and the chamfer of the other end of the bolt hole 301; at the same time, the milling mechanism 3 is able to perform milling on the corresponding other flange 300, thereby forming an internal spline 302 (as shown in FIG. Figure 20 As shown). That is to say, the second turning process and the milling process are also carried out simultaneously, which further improves the efficiency of production and processing; moreover, since the support seat 5 on the right side also rotates clockwise, the inner annular surface of the flange 300 can be turned and chamfered by the first turning process (or the second turning process) before the milling process, thereby providing the necessary processing foundation for milling the internal spline 302. After the flange 300 has been milled, the right support seat 5 continues to be controlled to rotate clockwise until the corresponding clamping mechanism 6 faces the blanking station, and the flange 300 can be removed to complete the blanking operation; after removing the flange 300, the corresponding clamping mechanism 6 can continue to rotate clockwise with the right support seat 5, so as to re-clamp the flange 300 on the left clamping mechanism 6.

[0050] like Figures 2 to 4 As shown, the loading station and the unloading station are set in the same operating area 200, that is, the loading station and the unloading station are located between the drilling mechanism 1 and the milling mechanism 3, and are located in front of the turning mechanism 2. Figure 2 As shown, when the loading operation is performed, one end of the left support base 5 faces the operating area 200 to perform a loading operation, and the two ends of the right support base 5 just face the turning mechanism 2 and the milling mechanism 3, so that a flange 300 can be turned for the second time and a flange 300 can be milled at the same time as the loading operation. Figure 3As shown, when performing the blanking operation, one end of the support seat 5 on the right side faces the operating area 200 for a single blanking operation, and both ends of the support seat 5 on the left side face the drilling mechanism 1 and the turning mechanism 2, so that while blanking, a flange 300 can be drilled and a flange 300 can be turned for the first time. In other words, the above processing method can greatly improve production efficiency. In addition, the loading station and the blanking station can be located in the same operating area 200, and the loading and blanking operations can be staggered, so that only one operator is required to complete all operations, thereby reducing the demand for labor. Moreover, during the entire processing process, for the same flange 300, the operator only needs to complete one clamping and positioning operation and one removal operation, which reduces the workload and improves work efficiency. In addition, since the turning mechanism 2 can be horizontally rotatably arranged behind the two support seats 5, when performing loading operations, the turning mechanism 2 rotates counterclockwise to the clamping mechanism 6 on the support seat 5 facing the right, thereby performing a second turning process on the corresponding flange 300; when performing unloading operations, the turning mechanism 2 rotates clockwise to the clamping mechanism 6 on the support seat 5 facing the left, thereby performing a first turning process on the corresponding flange 300; that is, the CNC machine tool only needs to be equipped with one turning mechanism 2, and the equipment cost is lower.

[0051] It should be noted that the above-mentioned drilling mechanism 1, turning mechanism 2 and milling mechanism 3 are all prior art and will not be described in detail in this application. In addition, this application does not limit the horizontally rotatable installation method of the turning mechanism 2. For example, the entire turning mechanism 2 is installed on a rotating platform. By controlling the horizontal rotation of the rotating platform, the horizontal rotation of the turning mechanism 2 can be achieved, so that the turning mechanism 2 can alternately perform the first turning process and the second turning process. In addition, this application does not limit the horizontally rotatable installation method of the support seat 5. For example, a vertical shaft 52 is installed on the lower side of the support seat 5. The vertical shaft 52 is rotatably installed inside the frame 4 through bearings and bearing seats. At the same time, a servo motor is installed inside the frame 4. The output shaft of the motor is connected to the vertical shaft 52 through a transmission mechanism, so that the servo motor can drive the vertical shaft 52 (i.e., the support seat 5) to rotate horizontally to a specified angle to complete the corresponding operation.

[0052] Reference Figure 5 、 Figure 6 as well as Figure 8In this embodiment, the four clamping mechanisms 6 each include a box body 61, a rotating shaft 62, a driving member and a clamping member 63; the two box bodies 61 are respectively arranged at the two ends of the support on the left, and the distance between the two box bodies 61 and the rotation axis of the support seat 5 is equal; the other two box bodies 61 are respectively slidably arranged on the support seat 5 on the right, and the sliding directions of the two box bodies 61 are parallel to each other; the four rotating shafts 62 are respectively rotatably arranged on the four box bodies 61, and the two rotating shafts 62 located on the same box body 61 are coaxially arranged in the horizontal direction; the four driving members are respectively arranged inside the four box bodies 61, and the four driving members are respectively used to drive the four rotating shafts 62 to rotate; the four clamping members 63 are respectively coaxially arranged at the outer ends of the four rotating shafts 62, and the four clamping members 63 are respectively used to automatically clamp or loosen the flange 300. The flange 300 is clamped and positioned by the clamping member 63. When the driving member drives the rotating shaft 62 to rotate, the rotating shaft 62 drives the corresponding clamping member 63 to rotate. When the clamping member 63 rotates, the flange 300 clamped on the clamping member 63 also rotates. When the drilling mechanism 1 uses a single drill bit, after each bolt hole 301 is drilled, the clamping member 63 rotates the flange 300 by 60° (60° is the angle between two adjacent bolt holes 301. The flange 300 has six bolt holes 301, i.e., the angle between two adjacent bolt holes 301 is 60°), thereby continuing to drill the next bolt hole 301, and so on, until all six bolt holes 301 are drilled. When the turning mechanism 2 is a lathe, during the first and second turning operations, the driving member drives the rotating shaft 62 to rotate at high speed, which drives the clamping member 63 (i.e., the flange 300) to rotate at high speed, thereby achieving the turning operation. It should be noted that the present application does not limit the rotatable installation method of the rotating shaft 62. For example, the rotating shaft 62 is rotatably mounted on the box body 61 via a bearing. In addition, the driving member itself is a prior art. For example, the driving member is a motor, and the output shaft of the motor is connected to the rotating shaft 62 via a transmission mechanism, so that the rotating shaft 62 can be driven by the motor to rotate. In addition, the present application does not limit the sliding installation method of the two boxes 61 on the right support base 5. For example, a guide rail is provided on the support base 5, and the guide groove at the lower end of the box body 61 is slidably connected to the guide rail, and the box body 61 is driven to slide horizontally by a screw drive mechanism.

[0053] Reference Figure 6 、 Figure 8 as well as Figures 9 to 13 In this embodiment, the clamping member 63 includes a housing 631, a cover 632, a slider 633, a piston ring 634, a first spring 635, a second spring 636 and a third rotary joint 637. Figure 9 and Figure 10As shown, the open end of the housing 631 is coaxially connected to the rotating shaft 62 through the cover 632; the end surface of the housing 631 away from the rotating shaft 62 is provided with at least three slide grooves 6311 in the radial direction, the angles between two adjacent slide grooves 6311 are equal, and the inner wall of each slide groove 6311 is provided with a limiting groove 6312 for communicating with the interior of the housing 631 (as shown in FIG. Figure 10 and Figure 13 as shown); Figures 9 to 11 As shown, the number of the sliders 633 is at least three, and each slider 633 is slidably connected to each slide groove 6311, and a seal is formed between the slider 633 and the corresponding limit groove 6312 (as shown in FIG. Figure 13 As shown, the limiting groove 6312 is sealed by the slider 633 to prevent the debris generated during the processing and the coolant from entering the interior of the housing 631 through the limiting groove 6312); Figures 11 to 13 As shown, each slider 633 is provided with a clamping block 6331 on the side away from the cover body 632, and each slider 633 is provided with a clamping block 6332 on the side close to the cover body 632; each clamping block 6332 is slidably connected to each limit groove 6312, and each clamping block 6332 is provided with a conical surface 6333 on one end close to the cover body 632; the number of the first springs 635 is at least three, and each first spring 635 is arranged inside the housing 631, and each first spring 63 5 are used to drive each block 6332 to slide radially outward; the piston ring 634 is axially slidably arranged inside the housing 631, and a conical ring surface 6341 is provided between the end surface of the piston ring 634 away from the cover body 632 and the inner ring surface, and a closed chamber 638 is formed between the piston ring 634, the housing 631 and the cover body 632; the second spring 636 is arranged inside the housing 631, and the second spring 636 is used to drive the piston ring 634 to slide in the direction close to the cover body 632. A channel 621 (such as Figure 12 As shown), the rotation port of the third rotary joint 637 is coaxially connected to the end of the channel 621 away from the chamber 638, and the fixed end of the third rotary joint 637 is fixed to the corresponding box 61 (as shown Figure 6 or Figure 8 As shown). Figure 12 and Figure 13As shown, when liquid or gas is filled into chamber 638 through third rotary joint 637 until piston ring 634 is driven to slide away from cover 632, conical ring surface 6341 forces each clamping block 6332 to slide radially inward via each conical surface 6333, thereby automatically clamping flange 300 between each clamping block 6331. When the liquid or gas in chamber 638 is exhausted, piston ring 634, under the action of second spring 636, slides toward cover 632, thereby automatically resetting. At this time, each clamping block 6332 also slides radially outward under the action of first spring 635, thereby automatically loosening the flange 300 clamped between each clamping block 6332. The rotating port and fixed end of third rotary joint 637 are capable of relative rotation, allowing liquid (or gas) to be introduced into or removed from channel 621 while the fixed end of third rotary joint 637 remains stationary and rotary shaft 62 rotates.

[0054] Reference Figure 6 as well as Figure 7 In this embodiment, the CNC machine tool further includes a first supply member 7, which includes a first rotary joint 71, a first main pipe 72, two first branch pipes 73, and two first control valves 74. The first rotary joint 71 is coaxially arranged on the rotation axis of the left support base 5, and the rotation port of the first rotary joint 71 is connected to the first main pipe 72. One end of the two first branch pipes 73 is respectively connected to the fixed end of the first rotary joint 71, and the other end of the two first branch pipes 73 is respectively connected to the fixed end of the corresponding two third rotary joints 637. The two first control valves 74 are respectively provided on the two first branch pipes 73. When the first main pipe 72 is externally connected to positive pressure (i.e., liquid or gas is supplied to the first main pipe 72), the corresponding first control valve 74 is opened to supply liquid or gas to the corresponding third rotary joint 637, thereby clamping the flange 300. When the first main pipe 72 is externally connected to negative pressure, the corresponding first control valve 74 is opened to discharge the liquid or gas in the corresponding third rotary joint 637, thereby releasing the clamping effect on the flange 300. In addition, the rotating port and fixed end of the first rotating joint 71 are allowed to rotate relative to each other. Therefore, when the support base 5 rotates, the fixed end of the first rotating joint 71 can adaptively rotate relative to the rotating port of the first rotating joint 71 (i.e., the first main pipe 72), thereby avoiding interference. In addition, since there is no relative sliding between the box 61 on both sides of the first rotating joint 71 and the support base 5 below, the first branch pipe 73 can adopt a rigid structure, thereby eliminating the need to fix the fixed end of the first rotating joint 71 through the bracket 51. Of course, the first branch pipe 73 can also adopt a flexible structure, in which case the fixed end of the first rotating joint 71 needs to be fixed through the bracket 51.

[0055] Reference Figure 8 In this embodiment, the CNC machine tool also includes a second supply part 8, which includes a second rotary joint 81, a second main pipe 82, two second branch pipes 83 and two second control valves 84; the second rotary joint 81 is arranged on the right support seat 5 through the bracket 51, and the axis of the second rotary joint 81 coincides with the rotation axis of the support seat 5; the rotation port of the second rotary joint 81 is connected to the second main pipe 82; the two second branch pipes 83 are both flexible structures or retractable structures, one end of the two second branch pipes 83 is respectively connected to the fixed end of the second rotary joint 81, and the other end of the two second branch pipes 83 is respectively connected to the fixed end of the corresponding two third rotary joints 637, and the two second control valves 84 are respectively arranged on the two second branch pipes 83. Similarly, when the second manifold 82 is externally connected to positive pressure (i.e., liquid or gas is supplied to the second manifold 82), the corresponding second control valve 84 is opened, and liquid or gas can be supplied to the corresponding third rotary joint 637, thereby clamping the flange 300; when the second manifold 82 is externally connected to negative pressure, the corresponding second control valve 84 is opened, and the liquid or gas in the corresponding third rotary joint 637 can be discharged, thereby releasing the clamping effect on the flange 300. In addition, the rotation port and the fixed end of the second rotary joint 81 can be allowed to rotate relative to each other. When the support base 5 rotates, the fixed end of the second rotary joint 81 can be adaptively rotated relative to the rotation port of the second rotary joint 81 (i.e., the second manifold 82), thereby avoiding interference. In addition, since the box 61 on both sides of the second rotary joint 81 is slidably connected to the support base 5 below, the second branch pipe 83 is a flexible or retractable structure to avoid interference with the position of the sliding adjustment box 61.

[0056] Reference Figure 12 as well as Figure 13 In this embodiment, the end surface of the housing 631, facing away from the cover 632 and corresponding to the center hole of the flange 300, is recessed toward the cover 632 to form a clearance groove 6313. This clearance groove 6313 prevents accidental contact with the turning tool during turning the center hole of the flange 300 and also prevents accidental contact with the milling tool during milling of the internal spline 302. The sidewalls of the clearance groove 6313 and the side surface of the retaining block 6332 are each provided with a receiving hole 6314 for accommodating the end of the first spring 635. This receiving hole 6314 facilitates installation of the first spring 635.

[0057] Reference Figure 12 as well as Figure 13In this embodiment, an annular groove 6342 is coaxially defined on the outer surface of the piston ring 634 at one end away from the cover 632. The second spring 636 is sleeved within the annular groove 6342, and the outer diameter of the second spring 636 is smaller than that of the piston ring 634. The annular groove 6342 facilitates the installation of the first spring 635. Furthermore, the outer diameter of the second spring 636 is smaller than that of the piston ring 634, so the second spring 636 does not contact the inner surface of the housing 631, thereby preventing wear on the inner surface of the housing 631 and thus preventing damage to the seal between the piston ring 634 and the housing 631.

[0058] Reference Figure 9 as well as Figure 10 In this embodiment, a clearance hole 6315 is provided on the end surface of the shell 631 away from the cover body 632 and corresponding to the position of the bolt hole 301 of the flange 300 toward the cover body 632. The clearance hole 6315 can prevent the drill bit from accidentally hitting the drill bit during the drilling process.

A mounting hole 521 is coaxially and upwardly penetrated at the lower end of the vertical shaft 52; the CNC machine tool also includes two power supply components 9, and the two power supply components 9 include an upper insulating cover 91, a lower insulating cover 92, at least two upper conductive rings 93, at least two lower conductive rings 94, at least two upper wires 95 and at least two lower wires 96; the two upper insulating covers 91 are coaxially arranged at the lower ends of the two mounting holes 521, and the two lower insulating covers 92 are coaxially and rotatably arranged at the lower ends of the two upper insulating covers 91, and the lower insulating covers 9 2 forms a seal with the corresponding upper insulating cover 91; at least two upper conductive rings 93 are coaxially spaced apart and arranged on the inner top of the corresponding upper insulating cover 91, and at least two lower conductive rings 94 are coaxially spaced apart and arranged on the inner bottom of the corresponding lower insulating cover 92, and each lower conductive ring 94 is in contact and conduction with the corresponding upper conductive ring 93; one end of at least two upper wires 95 are spaced apart and arranged on the upper end of the upper insulating cover 91, and each upper wire 95 is in contact and conduction with the corresponding upper conductive ring 93; one end of at least two lower wires 96 are spaced apart and arranged on the lower end of the lower insulating cover 92, and each lower wire 96 is in contact and conduction with the corresponding lower conductive ring 94. Figure 17 and Figure 18As shown, by fixing the upper insulating cover 91 at the lower end of the mounting hole 521, and leading the upper wire 95 out from the upper end of the mounting hole 521, and then connecting it to the location where electricity is needed (such as the first control valve 74, the second control valve 84, the motor that drives the rotating shaft 62 to rotate, and the motor on the screw drive mechanism, etc.); fixing the lower insulating cover 92 below the vertical shaft 52, and connecting it to the external power supply through the lower wire 96; then when the support seat 5 (i.e., the vertical shaft 52) ​​rotates, the upper insulating cover 91 and the upper conductive ring 93 inside it will rotate with the vertical shaft 52, while the lower insulating cover 92 and the lower conductive ring 94 inside it are fixed, and in this process, the upper conductive ring 93 and the corresponding lower conductive ring 94 are always in contact and conductive, so that the power input can be realized when the support seat 5 always rotates clockwise. Among them, this application does not limit the rotation connection method between the upper insulating cover 91 and the lower insulating cover 92. For example, Figure 18 As shown, the inner ring surface of the upper insulating cover 91 coaxially protrudes with a protruding ring 911, and the outer ring surface of the lower insulating cover 92 is provided with an annular groove 921 (the positions of the protruding ring 911 and the groove 921 are interchangeable). The protruding ring 911 is engaged in the groove 921, and the protruding ring 911 and the groove 921 can generate relative rotation. Of course, this method of cooperation between the protruding ring 911 and the groove 921 is also applicable to the upper conductive ring 93 and the lower conductive ring 94.

[0060] Reference Figure 17 In this embodiment, the power supply 9 further includes a protective cover 97, which is detachably mounted on the upper end of the mounting hole 521. A wire hole 971 is formed through the protective cover 97. The protective cover 97 seals the upper end of the mounting hole 521 to prevent debris and coolant generated during processing from entering the mounting hole 521. Furthermore, the wire hole 971 allows the upper conductive wire inside the mounting hole 521 to be led out.
