[0042] See also Figure 1 、 Figure 5 、 Figure 6 and Figure 7The present invention provides a badminton racket drilling machine. The hole processing body 3 includes a carrier plate 31 fixed to the track transposition body 2 on the top left side. A sheath 32 is fixed through the middle side of the carrier plate 31. A threaded vertical rod 34 is rotatably passed through the inside of the sheath 32, and a turntable 33 is locked and fixed on the top of the threaded vertical rod 34.

A drilling structure 37 is locked and fixed at the bottom of the hollow cylinder 35 to facilitate changing the vertical height of the drilling structure 37, so as to better align with the hole to be processed and ensure the drilling effect of the badminton racket.

[0043] Among them, the drilling structure 37 includes a support plate 371 locked and fixed to the bottom of the hollow cylinder 35, and a second motor 372 is locked and fixed to the left side of the bottom of the support plate 371.

[0046] The present invention also provides a method for using a badminton racket drilling machine. When using the badminton racket drilling machine, the badminton racket is first placed horizontally on a processing platform, and the racket frame of the badminton racket is clamped and fixed using a clamping device to ensure that the elliptical structure of the racket frame remains stable and the area to be processed is unobstructed. Then, the badminton racket drilling machine is installed on the processing platform to perform a drilling operation. The specific steps are as follows:

[0047] First, according to the shape and size of the badminton racket to be drilled, loosen the fastening bolts 121 on the bracket 12, move the rectangular rod 17 laterally to drive the support frame 15 and the entire track transposition body 2 to move relative to the bracket 12, thereby adjusting the major axis size of the elliptical trajectory. After adjustment, re-tighten the fastening bolts 121, and then manually rotate the screw rod 27 to drive the internal threaded support block 25 to move along the groove seat 26 through the screw rod 27, thereby driving the crossbar frame 24 and the hole processing body 3 to move relative to the stand 21, thereby adjusting the minor axis size of the elliptical trajectory. Through the above adjustment, the elliptical motion trajectory of the hole processing body 3 is subsequently determined to match the elliptical shape of the badminton racket frame.

[0048] Second, manually rotate the turntable 33 to drive the threaded rod 34 to rotate. Under the guidance of the guide column 36, the hollow cylinder 35 drives the drilling structure 37 to descend as a whole until the tip of the drill bit 37510 is at the preset height position of the hole to be processed inside the badminton racket frame;

[0049] Third, the first motor 112 of the driving steering structure 11 is started, and the driving cylinder sleeve 116 and the support 12 are driven to revolve around the axis of the column 18 through the meshing transmission of the worm 113 and the worm wheel 115. At the same time, the revolution of the support 12 is converted into the rotation of the movable bevel gear 13 through the meshing of the fixed bevel gear 119 and the movable bevel gear 13. The power is transmitted to the first bevel gear 16 through the shaft 14, and then the vertical column 19 is driven to rotate through the second bevel gear 18. The revolution of the support 12 and the rotation of the movable bevel gear 13 are combined, and the hole processing body 3 and the drill bit 37510 thereon are finally driven to generate a stable and parameter-adjustable elliptical motion track through the track transposition main body 2. The drill bit 37510 is controlled to move along the elliptical track and accurately positioned to the center of the first hole to be processed by starting and stopping the first motor 112.

[0050] Fourth, the second motor 372 of the drilling structure 37 is started to drive the driving gear 373 to rotate, and the whole push-positioned hole drilling assembly 375 is driven to rotate horizontally around the positioning column 376 axis through the meshing with the driven gear ring 374 until the axis of the drill bit 37510 is adjusted to be consistent with the normal direction of the current hole to be processed on the badminton racket.

[0051] Fifth, the fourth motor 3759 is started to drive the drill bit 37510 to rotate at high speed, and the third motor 3752 of the push-positioned hole drilling assembly 375 is driven to rotate the threaded cross rod 3753, so that the displacement block 3755 drives the drill bit 37510 to stably feed radially to the direction of the badminton racket frame under the guidance of the slide rod 3757 and the anti-overturning protection of the T-shaped slot, until the drill bit 37510 completes the drilling processing of the hole. Then, after the drilling is completed, the third motor 3752 is controlled to reverse, so that the displacement block 3755 drives the drill bit 37510 to retreat radially to the initial safe position.

[0052] Sixth, the first motor 112 of the driving steering structure 11 is started again to drive the hole processing body 3 to move to the next hole to be processed along the elliptical track, and the above steps four and five are repeated until the processing of all the preset holes on the badminton racket frame is completed. After the processing of all the holes is completed, the hole processing body 3 is controlled to rise and reset, the clamping device is loosened, and the processed badminton racket is taken out.

[0053] The above only describes the preferred examples of the present application and is not used to limit the present application.
