[0022] As attached Figure 1 and Figure 2 As shown in an illustrative embodiment of the drilling device for machining with conversion function of the present invention, the drilling device includes a worktable 100; a fixed bracket 200 having a vertical part and a horizontal part, the vertical part being movably disposed on the side of the worktable 100, and the horizontal part being parallel to the worktable 100 and located above the worktable 100; a drilling mechanism being drivably disposed below the horizontal part; a driving mechanism for controlling the movement of the drilling mechanism in the horizontal and vertical directions, the driving mechanism including a first driving component and a second driving component, the first driving component and the second driving component being slidably connected to the drilling mechanism relative to the horizontal part through a sliding structure; and a clamping and fixing mechanism adapted to the size of the workpiece to be processed and movably disposed on the upper surface of the worktable 100. The present invention can rotate the drill bit 330 of the required size to the lowest position and fix the drill bit 330 after adjustment, for drilling workpieces of different sizes, and can quickly complete the drilling requirements of different hole diameters, thus improving drilling efficiency.

[0023] The workbench 100 of the machining drilling device of the present invention with conversion function has a movable groove 110 on one side, and a fixed bracket 200 is slidably connected inside the movable groove 110. A notch 210 is opened in the horizontal part of the fixed bracket 200.

[0024] As attached Figure 1-7 As shown, the drilling mechanism of the machining drilling device with conversion function of the present invention includes a housing 310 connected to a sliding structure via a first drive assembly, a mounting part 320 in the shape of an annulus 350 and rotatably disposed on the housing 310, a plurality of drill bits 330 detachably disposed on the annular outer periphery of the mounting part 320, and a locking structure for locking the plurality of drill bits 330. (See attached diagram) Figure 1 and Figure 2 As shown, the first drive assembly includes two sliding grooves 430, symmetrically arranged inside the pre-set notch 210 in the horizontal section; a slide block 440, spanning the two sliding grooves 430 and slidably disposed on the two sliding grooves 430; and a third electric telescopic rod 450, disposed inside the slide block 440, with its output end fixedly connected to the housing 310. The telescopic movement of the third electric telescopic rod 450 drives the housing 310 connected to its output end to move vertically, thereby adjusting the height of the drill bit 330 as needed. (See attached diagram) Figure 3-7 As shown, multiple connecting shafts 321 are rotatably connected to the inner side of the mounting part 320. One end of each connecting shaft 321 near the inner wall of the mounting part 320 is inserted into a connecting post 322. The other end of the connecting post 322 passes through a mounting through hole 326 on the mounting part 320 and connects to a drill bit 330. A limiting bearing 331 is rotatably connected to the outer side of each drill bit 330. Preferably, the connecting post 322 has a regular square prism structure, and the connecting post 322 and the drill bit 330 are integrally formed. The locking structure further includes a ring 350, which is mounted on the mounting part 320 via symmetrically arranged first electric telescopic rods 325. The ring 350 reciprocates relative to the mounting part 320 through the telescopic movement of the first electric telescopic rods 325. Multiple locking fasteners 360 are arranged along the outer periphery of the ring 350, and the multiple locking fasteners 360 lock the multiple drill bits 330 in a snap-fit ​​manner. Preferably, the locking fastener 360 has a limiting groove 361 and an arc-shaped groove 362 on the side near the mounting part 320, and the limiting groove 361 and the arc-shaped groove 362 are connected. The limiting groove 361 engages with the corresponding limiting bearing 331, and the shape of the arc-shaped groove 362 is adapted to the contour of the drill bit 330 to accommodate the drill bit 330. When the drill bit 330 needs to be disassembled, firstly, the first electric telescopic rod 325 is extended, which drives the ring 350 connected to the output end of the first electric telescopic rod 325 to disengage the locking fastener 360 from the outside of the drill bit 330 and the limiting bearing 331. Then, the drill bit 330 is pulled out from the inside of the mounting through hole 326, so that the insertion post 322 is disengaged from the outside of the connecting shaft 321, thus completing the disassembly of the drill bit 330.

[0025] As attached Figure 6As shown, the drilling mechanism of the machining drilling device with conversion function of the present invention further includes a first motor 313, a rotating shaft 314, and a second electric telescopic rod 311 disposed in the housing 310. One end of the rotating shaft 314 is connected to the output shaft of the first motor 313, and the other end of the rotating shaft 314 passes through the housing 310 and is connected to the mounting part 320. A square block 315 is sleeved on the outer side of the end of the rotating shaft 314 near the mounting part 320. The output end of the second electric telescopic rod 311 is slidably connected to the square block 315 through a U-shaped locking block 312. By starting the first motor 313, the rotating shaft 314 connected to the output shaft of the first motor 313 is driven to rotate, which in turn drives the mounting part 320 to rotate at a certain angle, thereby enabling the drill bit 330 of the required size to be rotated to the bottom for drilling. This solves the technical problem in the prior art that drilling equipment needs to drill different diameter holes in the same workpiece, requiring frequent changes of different models of drill bit 330, making it difficult to quickly complete the drilling requirements and resulting in low drilling efficiency. The extension and retraction of the second electric telescopic rod 311 causes the U-shaped locking block 312 to engage or disengage from the square block 315, thereby fixing and releasing the relative position of the housing 310 and the mounting part 320. This ensures the drill bit 330 is fixed after position adjustment, preventing instability during operation. Specifically, when the mounting part 320 needs to be rotated, first, the second electric telescopic rod 311 is shortened to disengage the U-shaped locking block 312 from the outside of the square block 315. Then, the first motor 313 is started, driving the rotating shaft 314 connected to the output shaft of the first motor 313 to rotate the mounting part 320 by a certain angle. Finally, the second electric telescopic rod 311 is extended again to engage the U-shaped locking block 312 with the square block 315, thus fixing the rotated mounting part 320.

[0026] As attached Figure 6 As shown, the mounting part 320 of the machining drilling device with conversion function of the present invention is further provided with a third motor 340, a driving bevel gear 324, and a plurality of driven bevel gears 323. The third motor 340 is located on one side of the mounting part 320, and its output shaft passes through the mounting part 320 and is sleeved on the driving bevel gear 324. Each driven bevel gear 323 is respectively sleeved on the end of the connecting shaft 321 connected to the corresponding drill bit 330, and each driven bevel gear 323 meshes with the driving bevel gear 324. By starting the third motor 340, the driving bevel gear 324 connected to the output shaft of the third motor 340 is driven to rotate, which in turn drives the connecting shaft 321 connected to the driven bevel gears 323 to rotate, thereby driving the drill bit 330 connected to the connecting shaft 321 to rotate, enabling the drill bit 330, which has rotated to the working position, to perform drilling operations.

[0027] As attached Figure 1 and Figure 2As shown, the second drive assembly of the drive mechanism of the machining drilling device with conversion function of the present invention further includes a fourth electric telescopic rod 460 disposed in the vertical part, and the output end of the fourth electric telescopic rod 460 is fixedly connected to the slide 440. The extension and retraction of the fourth electric telescopic rod 460 drives the slide 440 connected to the output end of the fourth electric telescopic rod 460 to move back and forth, drives the housing 310 connected to the slide 440 to move back and forth, and further drives the mounting part 320 to move back and forth, so as to realize the adjustment of the horizontal position of the drill bit 330.

[0028] As attached Figure 2 As shown, the driving mechanism of the machining drilling device with conversion function of the present invention further includes a second motor 410 fixedly installed on one side of the worktable 100, and a lead screw 420 installed in the movable groove 110 of the worktable 100 and passing through the vertical part. The lead screw 420 is screwed to the vertical part, one end of the lead screw 420 is connected to the output shaft of the second motor 410, and the other end of the lead screw 420 is connected to the end of the movable groove 110 away from the second motor 410. By starting the second motor 410, the lead screw 420 connected to the output shaft of the second motor 410 is driven to rotate, controlling the vertical part to move left and right, driving the housing 310 connected to the vertical part to move left and right, and further driving the mounting part 320 to move left and right, thereby realizing the adjustment of the horizontal position of the drill bit 330.

[0029] As attached Figure 1-2As shown in Figures 8-9, the clamping and fixing mechanism of the machining drilling device with conversion function of the present invention includes two fixing plates 510, symmetrically arranged on the upper surface of the worktable 100; two fifth electric telescopic rods 520, symmetrically arranged at both ends of the upper surface of the worktable 100 perpendicular to the fixed bracket 200, with one end of each fifth electric telescopic rod 520 fixedly connected to the corresponding fixing plate 510; and two connecting seats 530, disposed between the two fixing plates 510, with grooves 531 formed on the opposite surfaces of the two connecting seats 530, and the outputs of the corresponding fifth electric telescopic rods 520 fixedly connected to the opposite back surfaces of the two connecting seats 530. The worktable 100 has two protrusions 550, which are respectively inserted into the corresponding grooves 531. The protrusions 550 are in the shape of a convex character. Two clamping plates 540 are disposed between the two connecting seats 530. Each clamping plate 540 is fixedly connected to the corresponding protrusion 550. Preferably, the clamping plate 540 is in the shape of an L-shape, and the bottom of the L-shape of the clamping plate 540 is in contact with the upper surface of the worktable 100. Two stop blocks 560 are respectively inserted into the corresponding connecting seats 530 and in contact with the corresponding protrusions 550. The stop blocks 560 are in the shape of an L-shape, and a tension spring 570 is fixedly connected between the bent end of the stop block 560 and the connecting seat 530. In use, the clamping plate 540 of the clamping and fixing mechanism is engaged with the connecting seat 530 by a protrusion 550 and a groove 531. The elastic tension of the tension spring 570 allows the stop block 560, inserted inside the connecting seat 530, to fix the position of the protrusion 550. By pulling the stop block 560 away from the connecting seat 530, the tension spring 570 is stretched, allowing the stop block 560 to release its restriction on the position of the protrusion 550. This facilitates the removal of the protrusion 550 from the groove 531, making it easier to replace clamping plates 540 of different shapes and sizes, thus improving practicality. When it is necessary to disassemble the clamping plate 540, first pull the stop block 560 to stretch the tension spring 570, causing one end of the stop block 560 to release its restriction on the position of the protrusion 550. Then, move the clamping plate 540 forward to disengage the protrusion 550 from the groove 531.

[0030] As attached Figure 1-6As shown, the specific working process of the drilling device for machining with conversion function of the present invention is as follows: The workpiece to be processed is placed between two clamping plates 540 on the worktable 100; the fifth electric telescopic rod 520 is extended to fix the workpiece in place by the two clamping plates 540; the first motor 313 is started to drive the rotating shaft 314 to rotate, causing the mounting part 320 to rotate at a certain angle, rotating the drill bit 330 of the required size to the lowest position; the second electric telescopic rod 311 is then extended to engage the U-shaped locking block 312 with the square block 315, fixing the drill bit 330 after adjustment; the second motor 410 is started to drive the drilling device... The lead screw 420 connected to the output shaft rotates, causing the fixed bracket 200 to move laterally, adjusting the lateral position of the drill bit 330; the extension and retraction of the fourth electric telescopic rod 460 causes the slide block 440 to move back and forth relative to the worktable, adjusting the longitudinal position of the drill bit 330; the third motor 340 is started, driving the active bevel gear 324 connected to the output shaft of the third motor 340 to rotate, causing the connecting shaft 321 connected to the driven bevel gear 323 to rotate, thereby causing the insertion post 322 and the drill bit 330 to rotate; the extension and retraction of the third electric telescopic rod 450 causes the drill bit 330 to move vertically, adjusting the vertical position of the drill bit 330, and drilling the workpiece to be processed.

[0031] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
