Description

Technical Field

[0001] This invention relates to the field of intelligent machine tool technology, and more specifically, to a CNC boring and drilling integrated machine tool and its control system. Background Technology

[0002] Workpieces need to be machined before they can be used. Common machining tools include drill bits and boring tools. The more demanding the machinery, the smaller the tolerance requirements for its mechanical parts. Drill bits first create holes in the mechanical parts, which introduces a relatively large error at this stage. To reduce this error, boring tools are used to further machine the mechanical parts, thereby minimizing the overall error.

[0003] Chinese invention patent application number CN202311757868.1 discloses "a multi-position integrated machining center for milling, drilling, and boring, including a mounting and adjusting table, an electro-hydraulic push rod, a rotating support arm, a fixed support mounting frame, a first motor, a fixed support device, and a locking adjustment device. The locking adjustment device is mounted on the fixed support device, and the fixed support mounting frame is symmetrically arranged on one side of the locking adjustment device. The first motor is fixedly connected to the bottom end of the fixed support mounting frame, the rotating support arm is rotatably connected to the fixed support mounting frame, and the upper end of the first motor is fixedly connected to the rotating support arm. The electro-hydraulic push rod is fixedly mounted on the rotating support arm."

[0004] However, in actual use, the process of changing boring tools or drill bits is still cumbersome. Starting the mounting adjustment platform on the rotating support arm raises the platform and the equipment fixedly mounted on it. Starting the first motor drives the rotating support arm to rotate and swing on the fixed support mounting frame to adjust the position of the mounting adjustment platform and the equipment on it. When switching between drilling and milling boring equipment, the alignment of the drill bit and the tool accessories is also involved. Step-by-step operation leads to repeated positioning errors.

[0005] Chinese utility model patent application number CN201721777940.7 discloses "an automatic drilling and boring machine, wherein a support base is provided at the center of the top of the base, a column is provided at the rear of the upper surface of the support base, a hydraulic device is provided at the top of the column, a mounting base is provided at the front of the upper surface of the support base, two sets of hydraulic cylinders are provided at the top of the support base, and the two sets of hydraulic cylinders are respectively located at the front and rear ends of the mounting base. Two sets of second clamps are symmetrically connected to the top of the output ends of the two sets of hydraulic cylinders. The workpiece is clamped by the first and second clamps, the workpiece is clamped by the hydraulic device, the workpiece is bored by the boring head, and the workpiece is drilled by the drill rod. The present invention completes drilling and boring in one operation, effectively reducing the labor intensity of workers, is simple to use, and effectively improves work efficiency."

[0006] When machining mechanical parts, the drilled holes produced by drill bits have low precision. Therefore, it is usually necessary to first use a drill bit to open the hole and then use a boring head for fine operation. This requires secondary positioning of the workpiece and the spindle head. Secondary positioning will produce a large error, resulting in the workpiece not meeting the specified standards.

[0007] In conclusion, there is a need to develop or improve a more convenient and practical CNC boring and drilling integrated machine tool. Summary of the Invention

[0008] In view of this, and in order to solve the problems mentioned above, the present invention provides a CNC boring and drilling integrated machine tool and its control system, the specific technical solution of which is as follows:

[0009] A CNC boring and drilling integrated machine tool includes a support base, a guide rail mechanism, a tool mechanism, and a connecting mechanism;

[0010] The upper part of the support seat faces the workpiece holder. A through hole is opened at the center of the upper part of the support seat, and a clearance groove is also opened at the center of the upper part. The spindle head can pass through the through hole and the clearance groove in sequence. The upper part of the support seat also has two strip grooves that intersect the clearance groove in a cross shape, namely the first strip groove a and the second strip groove b. The lower part of the support seat faces away from the workpiece holder. The lower part of the support seat is axially movably connected to the workpiece processor.

[0011] The guide rail mechanism includes a first guide rail assembly fixedly installed in a first strip groove and a second guide rail assembly fixedly installed in a second strip groove.

The first drive motor also drives the first common rail component to rotate in direction two to connect to the third rail.

[0021] The second rotating assembly includes a second rack guide, a second drive motor, and a second common rail component. The second rack guide is disposed in the second mounting groove. The third drive end of the second drive motor meshes with the second rack guide. The fourth drive end of the second drive motor is movably connected to the bottom of one end of the second common rail component. The second drive motor drives the second common rail component to rotate in direction one to connect the second rail.

[0024] In some embodiments, the first rack guide extends toward the edge of the through hole in the direction of the through hole, and the second rack guide extends toward the edge of the through hole in the direction of the through hole;

[0025] In some embodiments, the boring tool assembly includes a first clamp and a boring tool;

[0026] The first clamp is L-shaped and has two guide wheels at its ends that are adapted to the first guide rail assembly. A cylindrical first locking member is provided at the top, which penetrates the plate of the first clamp. The middle part of the boring tool is detachably sleeved on the first locking member, and both ends protrude from the first locking member. One end of the boring tool is an insertion end, which is directly opposite the mounting part of the spindle head, and the two are inserted into each other.

[0027] The drill bit assembly includes a second clamp and a drill bit. The second clamp is L-shaped and has two guide wheels at its two ends that are adapted to the second guide rail assembly. A cylindrical second clamp is provided at the top, which penetrates the plate of the second clamp. The middle part of the drill bit is detachably fitted inside the second clamp, and both ends extend out of the second clamp. One end of the drill bit is an insertion end, which is directly opposite the mounting part of the spindle head, and the two are inserted into each other.

[0028] In some embodiments, two clamping rods are further included, which are telescopically disposed in opposite sidewalls of the clearance groove. The clamping rods can telescopically move toward the through hole. The top of the first clamp is also provided with a first positioning hole adapted to the clamping rod. The clamping rod can extend from the opposite sidewall of the clearance groove and be inserted into the first positioning hole.

[0029] In some embodiments, a telescopic mechanism is further included, wherein multiple telescopic mechanisms are provided, the working ends of the multiple telescopic mechanisms are fixedly connected to the support seat, and the sides of the multiple telescopic mechanisms are fixedly connected to the workpiece processor to drive the support seat to move toward or away from the spindle head.

[0030] A control system for a CNC boring and drilling integrated machine tool includes all the technical features of the CNC boring and drilling integrated machine tool and a central control component. The central control component is electrically connected to the support base, and its control process includes the following steps:

[0031] S1 The spindle head picks up the drill bit, controls the connecting mechanism to rotate to connect the second guide rail assembly, controls the drill bit assembly to move to the through hole, controls the bearing seat to move toward the spindle head, and the drill bit is inserted into the spindle head mounting part to complete the tool picking;

[0032] S2 drill bit machining, control the support seat away from the workpiece machiner, the second clamp moves to one side of the second guide rail assembly, control the connecting mechanism to reset, the support seat moves toward the workpiece machiner until the drill bit passes through the through hole to machine the workpiece;

[0033] S3 spindle head releases the drill bit, controls the carrier to move away from the workpiece processor, the connecting mechanism connects to the second guide rail assembly, the second clamp moves to the through hole, controls the carrier to move towards the workpiece processor, the drill bit is inserted into the second clamp of the second clamp and fixed, then controls the carrier to move away from the workpiece processor until the drill bit is completely pulled out from the spindle head, then the drill bit assembly moves to one side of the second guide rail assembly, and the connecting mechanism resets;

[0034] The S4 spindle head picks up the boring tool, controls the carrier to move away from the workpiece processor, the connecting mechanism connects to the first guide rail assembly, the boring tool assembly moves to the through hole, controls the carrier to move towards the workpiece processor, and the boring tool is inserted into the spindle head;

[0035] S5 boring tool machining: control the carrier to move away from the workpiece machiner, the first clamp moves to one side of the first guide rail assembly, control the carrier to move towards the workpiece machiner, the connecting mechanism resets, and the boring tool passes through the through hole to machine the workpiece;

[0036] When the S6 spindle head places the boring tool, after machining is completed, the carrier is controlled to move away from the workpiece machiner, the connecting mechanism connects to the first guide rail assembly, the first clamp moves to the through hole, the carrier is controlled to move towards the workpiece machiner, the boring tool is inserted into the first clamp, and then the carrier is controlled to move away from the workpiece machiner, and the boring tool assembly moves to one side of the first guide rail assembly.

[0037] The beneficial effects of this solution are as follows: the connecting mechanism can connect to the first guide rail assembly or the second guide rail assembly, so that the boring tool assembly or the drilling tool assembly can move to the through hole for the spindle head to change or remove the tool. Since the through hole is located at the center of the bearing seat, and the bearing seat and the spindle head of the workpiece processor are coaxial, the spindle head only needs to rotate to complete the tool change when changing or removing the tool, and the whole body does not need to move, so as to ensure that the central axis of the spindle head corresponds to the workpiece. This can reduce the secondary error caused by tool changing.

[0038] Secondly, since the through hole and the spindle head are coaxial, unnecessary wear will not be caused to the spindle head or tool mechanism of the workpiece processor when changing or removing the tool.

[0039] Finally, since the support is directly mounted on the workpiece processor, it occupies little space. Attached Figure Description

[0060] In this invention, the terms "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0061] Example 1

[0062] like Figures 1-2 As shown, a CNC boring and drilling integrated machine tool according to an embodiment of the present invention includes a transverse slide rail 100, a workpiece processor 200, a workpiece holder 300, and a support base 1. The workpiece processor 200 and the workpiece holder 300 are slidably disposed at both ends of the transverse slide rail 100. The workpiece processor 200 is provided with a spindle head 400 on one side facing the workpiece holder 300, and telescopic mechanisms 5 are provided on both sides. The working end of the telescopic mechanism 5 faces the workpiece holder 300, and the support base 1 is fixedly connected to the working end of the telescopic mechanism 5.

[0063] The support base 1 is also equipped with a guide rail mechanism 2, a cutting tool mechanism 3, and a connecting mechanism 4.

[0064] like Figures 1-3 As shown, the support base 1 is disc-shaped, with the upper part facing the workpiece holder 300. A through hole 114 is formed at the center of the upper part of the support base 1, and a circular clearance groove 11 is also formed at the center of the upper part. The spindle head 400 can pass through the through hole 114 and the clearance groove 11 in sequence. That is, the support base 1 is directly opposite the spindle head 400, and the spindle head 400 is directly aligned with the through hole 114. Therefore, when changing tools on the spindle head 400, there is no need for repositioning, reducing secondary errors caused by tool changes. Furthermore, since the tool changing process is always axial, there will be no skewed force that could scratch and wear the spindle head 400 and the tool.

[0065] The upper part of the support base 1 is also provided with two cross-shaped slots 12 intersecting the clearance slot 11, namely the first slot 12a and the second slot 12b. The first slot 12a, the second slot 12b and the clearance slot 11 are interconnected. The side of the support base 1 facing away from the workpiece holder 300 is the lower part, which is fixedly connected to the working end of the telescopic mechanism 5 provided on the workpiece processor 200. The telescopic mechanism 5 drives the support base 1 to move toward or away from the workpiece processor 200.

[0066] like Figures 3-6 As shown, the guide rail mechanism 2 includes a first guide rail assembly 21 fixedly installed in the first strip groove 12a and a second guide rail assembly 22 fixedly installed in the second strip groove 12b. The first guide rail assembly 21 and the second guide rail assembly 22 are respectively separated at the clearance groove 11, forming parts located on both sides of the clearance groove 11.

[0067] The first guide rail assembly 21 includes a first rail 211 and a second rail 212. The first rail 211 is installed on one side wall of the first strip groove 12a, and the second rail 212 is installed on the other opposite side wall of the first strip groove 12a. The second guide rail assembly 22 includes a third rail 221 and a fourth rail 222. The third rail 221 is installed on one side wall of the second strip groove 12b, and the fourth rail 222 is installed on the other opposite side wall of the second strip groove 12b.

[0068] The first track 211 and the second track 212 are offset in the height direction, as are the third track 221 and the fourth track 222. The first track 211 and the third track 221 are on the same horizontal plane, as are the second track 212 and the fourth track 222. Furthermore, the second track 212 and the fourth track 222 are vertically higher than the first track 211 and the third track 221. Since the first track 211 and the second track 212 are separated by the clearance groove 11, and the third track 221 and the fourth track 222 are also separated by the clearance groove 11, when connecting the separated first track 211, second track 212, third track 221, and fourth track 222 via the connecting mechanism 4, the vertical heights of the first track 211, second track 212, third track 221, and fourth track 222 must be offset to avoid collision with the connecting mechanism 4.

[0069] The diameter of the clearance groove 11 is greater than the width of the first strip groove 12a and the second strip groove 12b. The intersection of the extended central axes of the first track 211, the second track 212, the third track 221 and the fourth track 222 is located on the clearance groove 11. The connecting mechanism 4 rotates at the intersection of the extended central axes of the first track 211, the second track 212, the third track 221 and the fourth track 222 to connect the first track 211, the second track 212, the third track 221 and the fourth track 222.

[0070] like Figure 3 As shown, further, the two pairs of sidewalls of the first strip groove 12a are recessed, and the size of the two pairs of recesses in the first strip groove 12a is adapted to the size of the first track 211 and the second track 212. The first track 211 and the second track 212 are both located within the recesses in the two pairs of sidewalls of the first strip groove 12a. The two pairs of sidewalls of the second strip groove 12b are also recessed, and the third track 221 and the fourth track 222 are located within the recesses in the two pairs of sidewalls of the second strip groove 12b. The size of the two pairs of recesses in the second strip groove 12b is adapted to the size of the third track 221 and the fourth track 222. This allows the intersection of the extended central axes of the first track 211, the second track 212, the third track 221, and the fourth track 222 to be located away from the through hole 114, thus avoiding collisions when the connecting mechanism 4 and the spindle head 400 extend into the through hole 114.

[0071] like Figure 4 , Figure 7 and Figure 8 As shown, the tool mechanism 3 includes a boring tool assembly 31 and a drill bit assembly 32. The boring tool assembly 31 includes a first clamp 311 and a boring tool 312.

[0072] The first clamp 311 is L-shaped and has first guide wheels 314 on both sides of its ends that are adapted to the first guide rail assembly 21. A cylindrical first locking member 313 is provided at the top, penetrating the plate of the first clamp 311. The middle part of the boring tool 312 is detachably fitted onto the first locking member 313, with both ends extending out from it. The insertion end of the boring tool 312 faces the mounting part of the spindle head 400. The support seat 1 moves towards the spindle head 400. When the telescopic mechanism 5 drives the support seat 1 towards the spindle head 400, the spindle head 400 passes through the through hole 114 and the clearance groove 11 in sequence until the mounting part of the spindle head 400 engages with the boring tool 312. Through the rotation of the spindle head 400 itself and the movement of the support seat 1 away from the spindle head 400 driven by the telescopic mechanism 5, the boring tool 312 is removed from the first locking member 313.

[0073] The drill assembly 32 includes a second clamp 321 and a drill bit 322. The second clamp 321 is L-shaped and has two sides at its ends that are adapted to the second guide rail assembly 22. A cylindrical second clamp 323 is provided at the top. The second clamp 323 passes through the plate of the second clamp 321. The middle part of the drill bit 322 is detachably sleeved on the second clamp 323, and both ends extend out of the second clamp 323. The insertion end of the drill bit 322 is directly opposite the mounting part of the spindle head 400. The support seat 1 moves toward the spindle head 400. When the telescopic mechanism 5 drives the support seat 1 to move toward the spindle head 400, the spindle head 400 passes through the through hole 114 and the clearance groove 11 in sequence until the mounting recess of the spindle head 400 engages with the drill bit 322. By rotating the spindle head 400 itself and cooperating with the telescopic mechanism 5 to drive the support seat 1 to move away from the spindle head 400, the drill bit 322 is removed from the second clamp 323.

[0074] like Figure 8 As shown, the working principle of the first clamping member 313 and the second clamping member 323 for mounting the tool to the spindle head 400 is the same. Taking the first clamping member 313 as an example, the carrier 1 will move closer to the spindle head 400 until the insertion end of the boring tool 312 is inserted into the spindle head 400 and engaged. Then, the spindle head 400 rotates clockwise to disassemble the boring tool 312 from the first holder 311. Then, the carrier 1 will move away from the machine tool until the boring tool 312 is completely disengaged from the first holder 311. Then, the first holder 311 is reset along the first guide rail assembly 21 to one end of the first strip groove 12a.

[0075] The first guide wheel 314 is threaded (not shown in the figure), and its inner diameter at both ends is larger than that at the middle. Both ends of the first guide wheel 314 are threadedly connected to the first track 211, and its middle part is connected to the drive end worm gear of the drive motor mounted on the first gripper 311 (not shown in the figure). The other end of the first gripper 311 also has a first guide wheel 314. Two drive motors are respectively mounted on the two outer side walls of the L-shaped first gripper 311. When the two drive motors drive the two first guide wheels 314 to rotate, the first gripper 311 moves along the first track 211 and the second track 212.

[0076] like Figure 3 As shown, the opposite sidewalls of the clearance groove 11 are provided with a first mounting groove 111 and a second mounting groove 112.

[0077] like Figure 5 , Figure 9 As shown, the connecting mechanism 4 includes a first rotating assembly 41 and a second rotating assembly 42. The first rotating assembly 41 includes a first rack guide 411, a first drive motor 412, and a first common rail member 413. The first rack guide 411 is disposed in a first mounting groove 111 and is recessed. A rack is disposed on one side of the recess of the first rack guide 411. A first guide groove 4111 is formed at the bottom of the recess of the first rack guide 411 along the length direction of the first rack guide 411. The first drive end of the first drive motor 412 meshes with the rack of the first rack guide 411 and drives the first drive motor 412 to move along the first guide groove 4111. The second drive end of the first drive motor 412 is movably connected to the bottom of one end of the first common rail member 413 to drive the first common rail member 413 to rotate. The first common rail member 413 is located on the same horizontal plane as the first rail 211 and the third rail 221. The first rack guide member 411 extends towards the edge of the through hole 114 to allow the first common rail member 413 to connect to the first rail 211 or the third rail 221. The first drive motor 412 drives the first common rail member 413 to rotate in one direction to connect to the first rail 211; the first drive motor 412 also drives the first common rail member 413 to rotate in another direction to connect to the third rail 221.

[0078] Specifically, direction one refers to the first drive motor 412 driving the first common rail member 413 to rotate clockwise to connect to the first rail 211, that is, direction one is the clockwise rotation direction. Reverse two refers to the first drive motor 412 driving the first common rail member 413 to rotate counterclockwise to connect to the third rail 221, that is, reverse two is the counterclockwise rotation direction.

[0079] The two ends of the first common rail member 413 are inclined in opposite directions. The two ends of the partitions of the first rail 211 and the third rail 221 are also inclined in opposite directions and are adapted to the two ends of the first common rail member 413. The length of the first common rail member 413 is the same as the length of the partition of the first rail 211 or the third rail 221. Furthermore, when the first drive motor 412 moves to the joint point where the extended central axes of the first rail 211 and the third rail 221 meet, the connection point between the first common rail member 413 and the first drive motor 412 coincides with it.

[0080] The second rotating assembly 42 includes a second rack guide 421, a second drive motor 422, and a second common rail member 423. The second rack guide 421 is disposed in a first mounting groove 111 and is recessed. A rack is disposed on one side of the recess in the second rack guide 421. A second guide groove 4211 is formed at the bottom of the recess along the length of the second rack guide 421. The third drive end of the second drive motor 422 meshes with the rack of the second rack guide 421 and drives the second drive motor 422 to move along the second guide groove 4211. The fourth drive end of the second drive motor 422 is movably connected to the bottom of one end of the second common rail member 423 to drive the second common rail member 423 to rotate. The second common rail member 423 is located on the same horizontal plane as the second rail 212 and the fourth rail 222. The second rack guide member 421 extends towards the edge of the through hole 114 to allow the second common rail member 423 to connect to the first rail 211 or the third rail 221. The second drive motor 422 drives the second common rail member 423 to rotate in one direction to connect to the second rail 212; the second drive motor 422 also drives the second common rail member 423 to rotate in another direction to connect to the fourth rail 222.

[0081] The two ends of the second common rail member 423 are inclined in opposite directions. The two ends of the partitions of the second rail 212 and the fourth rail 222 are also inclined in opposite directions and are adapted to the two ends of the second common rail member 423. The length of the second common rail member 423 is the same as the length of the partition of the second rail 212 or the fourth rail 222. Furthermore, when the first drive motor 412 moves to the joint of the extended central axis of the first rail 211 and the third rail 221, the connection between the first common rail member 413 and the first drive motor 412 coincides with it.

[0082] The first rotating assembly 41 and the second rotating assembly 42 are configured identically. Taking the connection of the first track 211 as an example, the first drive motor 412 carries the first common track member 413 in the first mounting groove and moves along the first rack guide member 411 to the end of the first rack guide member 411. Then, the first drive motor 412 drives the first common track member 413 to rotate to be parallel to the first track 211. The first drive motor 412 carries the first common track member 413 along the first rack guide member 411 to the joint of the extended central axis of the first track 211 and the third track 221 to connect the first track 211.

[0083] like Figure 1 and Figure 10 As shown, the telescopic mechanism 5 is a pneumatic telescopic machine. Its working end is connected to the lower part of the bearing seat 1 to drive the bearing seat to move axially toward or away from the workpiece processor 200. That is, the telescopic mechanism 5 can be configured in various ways. Regardless of the configuration, the workpiece processor 200 can move axially toward or away from the workpiece processor 200.

[0084] Example 2

[0085] like Figures 3-5 As shown, the difference from Embodiment 1 is that it also includes at least two clamping rods 113, which are telescopically disposed in the opposite sidewalls of the clearance groove 11, and the clamping rods 113 extend and retract toward the through hole 114. The top of the first clamp 311 is also provided with a first positioning hole 315 adapted to the clamping rod 113. At the same time, the clamping rod 113 extends from the opposite sidewall of the clearance groove 11 and inserts into the first positioning hole 315, which improves the stability of the spindle head 400 engaging the boring tool 312 and avoids shaking. After the spindle head 400 has installed the boring tool 312, the clamping rod 113 is reset, and then the telescopic mechanism 5 raises the support seat 1, so that the boring tool 312 is disengaged from the first clamp 311.

[0086] The top of the second clamp 321 is also provided with a second positioning hole 325 that is adapted to the clamping rod 113. The working principle of the second clamp 321 is the same as that of the first clamp 311. That is, in the tool changing process of the drill assembly 32, the second positioning hole 325 abuts against the clamping rod 113 to facilitate stable tool changing of the spindle head 400.

[0087] The extension and retraction of the clamping rod 113 can be in various ways, such as rack and pinion, extension mechanism and rope pulley, etc., as long as the extension and retraction of the clamping rod 113 is sufficient to abut the first positioning hole 315 or the second positioning hole 325.

[0088] Example 3

[0089] The difference from Embodiment 1 is that the length of the first common rail member 413 is less than the length separating the first rail 211 or the third rail 221. When the first common rail member 413 is connected to the first rail 211 or the third rail 221, there is a gap between the two ends of the first common rail member 413 and the first rail 211 or the third rail 221. The length of the first common rail member 413 is less than the length separating the first rail 211 or the third rail 221, and the first common rail member 413 is rotatably connected to the first rail 211 or the third rail 221 to avoid collision with the first rail 211 or the third rail 221 when the first common rail member 413 rotates. Because the first guide wheel 314 of the first clamp 311 has an external thread, and the first common rail member 413 has an internal thread that matches the first rail 211, and when the first rail 211 and the first common rail member 413 are connected, the internal threads of both are also connected, so that the first guide wheel 314 can move from the first rail 211 to the first common rail member 413, so that the first clamp 311 needs to move to the through hole 114 to cooperate with the spindle head 400 for tool changing or tool removal. Specifically, when the first clamp 311 passes through the connection between the first rail 211 and the first common rail member 413, one end of the first guide wheel 314 moves to the first common rail member 413 first, and the other end of the first guide wheel 314 is located in the first rail 211. As the other end of the first guide wheel 314 also moves to the first common rail member 413, the first clamp 311 is located on the first common rail member 413.

[0090] The second common rail member 423 is configured the same as the first common rail member 413, and the second rail 212 and the fourth rail 222 are configured the same as the first rail 211 and the third rail 221. Therefore, the movement between the second common rail member 423 and the second guide wheel 324 will not be described further.

[0091] Example 4

[0092] The difference from Embodiment 1 is that the support seat 1 is plate-shaped, and the shape of the support seat 1 does not affect the spindle head 400 from taking the tool from the support seat 1.

[0093] Example 5

[0094] like Figures 10-11 As shown, the machining process of the control system of the CNC boring and drilling integrated machine tool is as follows:

[0096] S2 drill bit machining: control the bearing seat 1 away from the workpiece machiner 200, the second clamp 321 moves to one side of the second guide rail assembly 22, control the connecting mechanism 4 to reset, the bearing seat 1 moves toward the workpiece machiner 200 until the drill bit 322 passes through the through hole 114, and the machining process is completed.

[0097] The S3 spindle head 400 places the drill bit, controls the bearing seat 1 to move away from the workpiece processor 200, the connecting mechanism 4 connects to the second guide rail assembly 22, the second clamp moves to the through hole 114, controls the bearing seat 1 to move towards the workpiece processor 200, the drill bit 322 is inserted into the second clamp 323 of the second clamp 321 and locked, controls the bearing seat 1 to move away from the workpiece processor 200 until the drill bit 322 is completely pulled out from the spindle head 400, then the drill bit assembly 32 moves to one side of the second guide rail assembly 22, and the connecting mechanism 4 resets.

[0098] The S4 spindle head 400 picks up the boring tool, controls the bearing seat 1 to move away from the workpiece processor 200, the connecting mechanism 4 connects to the first guide rail assembly 21, the boring tool assembly 31 moves to the through hole 114, controls the bearing seat 1 to move toward the workpiece processor 200, and the boring tool 312 is inserted into the spindle head 400.

[0099] S5 boring tool machining: control the carrier 1 to move away from the workpiece machiner 200, the first clamp 311 moves to one side of the first guide rail assembly 21, control the carrier 1 to move towards the workpiece machiner 200, the connecting mechanism 4 resets, and the boring tool 312 passes through the through hole 114 to machine the workpiece.

[0100] When the S6 spindle head 400 places the boring tool, after machining is completed, the control carrier 1 moves away from the workpiece processor 200, the connecting mechanism 4 connects to the first guide rail assembly 21, the first clamp 311 moves to the through hole 114, the control carrier 1 moves towards the workpiece processor 200, the boring tool 312 is inserted into the first clamp 311, and then the control carrier 1 moves away from the workpiece processor 200, the boring tool assembly 31 moves to one side of the first guide rail assembly 21.

[0101] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0102] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
