Detailed implementation method:

[0032] To enhance understanding of this utility model, it will be further described in detail below with reference to embodiments and accompanying drawings. This utility model can be implemented in the following ways:

[0033] Reference Figure 1-8 An automatic tapping device for a multi-axis swing arm for a faceplate frame includes a frame 1, a worktable 2, a casting fixture 3 mounted on the worktable 2, a multi-axis actuator 4 mounted above the casting fixture 3, and a drive source 5 for raising and lowering the multi-axis actuator 4 and for operation. The drive source 5 drives the multi-axis actuator 4 to raise and lower to tap all the column holes of the aluminum casting 6 (faceplate frame) on the casting fixture 3.

[0034] The multi-axis device 4 includes a gear plate 41 and a guide frame 42 disposed below the gear plate 41. The gear plate 41 and the guide frame 42 are connected by several connecting posts 43. Multiple linked gears 411 are disposed within the gear plate 41. The rotating spindle on the drive source 5 drives the gears 411 within the multi-axis device 4 to rotate via a connecting shaft 51. Multiple tapping swing arms 44 are detachably disposed at the bottom of the gear plate 41. Each tapping swing arm 44 includes a movable arm 441 and a working arm 442 disposed below the movable arm 441. One end of the movable arm 441 is connected to the gear 411 on the gear plate 41 via a hinge 443, and the other end is hinged to the movable arm 441. An external hexagonal rotating shaft 412 is mounted on the gear 411. The hinge 443 is connected to the external hexagonal rotating shaft 412, allowing the tapping swing arms 44 to rotate with the gear 411 to tap the pierced holes in the aluminum casting 6. The tapping arm 44 is detachably equipped with a tap 444 at its end. The tap 444 can be replaced with the corresponding model for different types of threaded holes, making it widely applicable. In this embodiment, the aluminum casting 6 has 12 threaded holes; therefore, the multi-spindle unit 4 in this embodiment is equipped with 12 tapping arms 44, processing 12 threads at once, significantly reducing processing costs for enterprises.

[0035] To adjust the position of the tapping arm 44, a rectangular guide rail 421 is provided at the bottom of the guide rail frame 42, and an adjustment component 45 for adjusting the tapping position of the tapping arm 44 is provided on the tapping arm 44. The adjustment component 45 is located below the guide rail frame 42 and is movably connected to the rectangular guide rail 421. The adjustment component 45 includes an adjustment frame 451 and a suspension member that movably suspends the adjustment frame 451 below the rectangular guide rail 421. When the suspension member is not locked, the position of the tapping arm 44 can be changed by adjusting the position of the adjustment frame 451. Specifically, the suspension member includes a suspension rod 452, a locking nut 453, and a washer 454 located above the locking nut 453. The suspension rod 452 and the locking nut 453 are threadedly connected. The top of the suspension rod 452 is slidably engaged in the rectangular guide rail 421, and the lower end of the suspension rod 452 passes through the adjustment frame 451 and is fixed in position by the locking nut 453. The adjusting frame 451 is provided with an elongated hole 4511 for the suspension rod 452 to move. One end of the adjusting frame 451 is provided with a mounting sleeve 4512 for fitting the adjusting frame 451 onto the tapping swing arm 44. When the locking nut 453 is tightened upwards and locked to the suspension rod 452, the adjusting frame 451 is fixed in place. If the position of the tapping swing arm 44 needs to be adjusted, simply loosen the locking nut 453 to change the position of the suspension rod 452 in the elongated hole 4511. The adjusting frame 451 can also rotate around the suspension rod 452 as an axis, thereby adjusting the position of the tapping swing arm 44. This design allows for a large adjustment range of the tapping swing arm 44 and a wide range of applications.

[0036] To secure the suspension rod 452 within the rectangular guide rail 421, the longitudinal section of the rectangular guide rail 421 is T-shaped. A locking cap 4521 extends radially outward from the top of the suspension rod 452, locking into the rectangular guide rail 421. The locking cap 4521 can slide within the rectangular guide rail 421, preventing the suspension rod 452 from falling out. To allow the suspension rod 452 to enter the rectangular guide rail 421, through holes 422 are provided at the four corners of the rectangular guide rail 421 for inserting or removing the top of the suspension rod 452. These through holes 422 communicate with the rectangular guide rail 421, and their diameter is larger than the diameter of the locking cap 4521, allowing the suspension rod 452 to enter and exit through the through holes 422. After the suspension rod 452 is inserted into the through hole 422, it can slide within the rectangular guide rail 421.

[0037] To prevent the multi-axis actuator 4 from shifting during lifting, a connecting plate 7 is fitted onto the top of the multi-axis actuator 4 at the connection point between the drive source 5 and the multi-axis actuator 4. Guide posts 8 are symmetrically arranged at both ends of the connecting plate 7, and the guide posts 8 rise and fall synchronously with the multi-axis actuator 4. A guide sleeve 9 is fitted onto the guide posts 8 at the bottom of the connecting plate 7, and the guide posts 8 rise and fall within the guide sleeve 9. This design ensures that the multi-axis actuator 4 remains vertical during lifting, preventing shifting.

[0038] To secure the aluminum casting 6, the casting fixture 3 includes a base plate 31 and a long-side limiting member 32 and a short-side limiting member 33 mounted on the base plate 31 for positioning the aluminum casting 6. The shapes of the long-side limiting member 32 and the short-side limiting member 33 are adapted to the aluminum casting 6. In this embodiment, the long-side limiting member 32 is "Z"-shaped, and the short-side limiting member 33 is "L"-shaped. The design of the long-side limiting member 32 and the short-side limiting member 33 can prevent the aluminum casting 6 from shifting during tapping, thus improving machining accuracy.

[0039] Working principle: First, place the aluminum casting 6 to be tapped into the casting fixture 3 in the reverse direction, so that the post hole 61 of the aluminum casting 6 faces the multi-spindle unit 4. Then, loosen the locking nut 453 on the suspension rod 452. By pushing or rotating the adjusting frame 451, make the tap 444 at the free end of each tapping arm 44 correspond one-to-one with each post hole 61 on the aluminum casting 6. Then tighten the locking nut 453 to fix the position of the tapping arm 44. Start the equipment. The rotating spindle on the drive source 5 drives the gear 411 in the multi-spindle unit 4 to rotate through the connecting shaft 51. The drive source 5 drives the multi-spindle unit 4 to descend, so that the tap 444 of the tapping arm 44 abuts against the post hole 61 and rotates forward to process the thread. When it contacts the limiter and moves upward, it rotates in the reverse direction to retract the tool, forming automatic tapping.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
