[0015] In addition, the present invention also provides a method of using a badminton racket drilling machine, which includes the following steps:

[0016] S1. According to the shape and size of the badminton racket to be drilled, adjust the position of the rectangular rod on the bracket laterally and fix the position by fastening bolts. Drive the internal thread support block along the slot seat through the screw to drive the crossbar frame and the hole processing body to change their initial position, and limit the hole processing body to make an elliptical motion trajectory that adapts to the shape and size of the badminton racket.

[0017] S2. The turntable of the main body for machining the hole position drives the threaded rod to rotate, causing the hollow cylinder to descend along the guide column, and bringing the drilling structure close to the height of the hole to be machined on the inside of the badminton racket.

[0018] S3. Start the drive steering structure to make the bracket rotate along the axis of the fixed bevel gear. Through the meshing transmission between the moving bevel gear and the fixed bevel gear, the shaft and the first bevel gear are driven to rotate. Then, through the second bevel gear, the column and the track shifting body are driven to make the hole processing body move in an elliptical trajectory to position the hole to be processed in different positions.

[0019] S4. Start the second motor of the drilling structure to drive the active gear and driven gear ring to rotate, so that the entire push-position drilling assembly rotates around the positioning column to a preset angle.

[0020] S5. Start the fourth motor to drive the drill bit to rotate, and then drive the threaded crossbar to rotate the third motor of the push-position drilling assembly, so that the shift block moves laterally along the slide bar, adjust the radial position of the drill bit, so that the drill bit can drill into the hole to be processed, and complete the processing of a single hole in the badminton racket.

[0021] S6. After resetting the drill bit, drive the steering mechanism again to move the drilling structure to the next hole to be drilled, until all holes of a single badminton racket are completed.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This invention utilizes the cooperation between the support and rotation body and the track shifting body to drive the hole processing body along an elliptical trajectory with adjustable parameters. This elliptical trajectory can be flexibly adjusted according to the elliptical frame size of different badminton racket models, by using a rectangular rod and lead screw mechanism to adjust the major and minor axes. This allows the drill bit to be precisely positioned to all the holes to be processed inside the racket frame, completing all drilling operations on the contour trajectory in one go. This effectively avoids errors caused by multiple clamping and positioning, significantly improving processing accuracy and production efficiency.

[0024] The hole-machining main body of this invention integrates multiple adjustment functions for height, angle, and radial feed. The overall height of the drill bit can be adjusted via a turntable to adapt to the thickness of the racket frame. The entire push-and-drill assembly can be driven to rotate horizontally via a second motor and gear transmission to adjust the drilling angle and ensure that it is consistent with the normal direction at the point to be processed on the racket frame. The threaded crossbar can be engaged with the shift block via a third motor to achieve precise radial feed of the drill bit. With its multi-degree-of-freedom adjustment capability, the equipment can adapt well to the processing of badminton rackets of different specifications and with different hole requirements, making it highly versatile.

[0025] This invention employs a multi-stage transmission structure including worm gears and bevel gears, supplemented by various guiding and limiting structures such as slide bars, T-slots, and guide columns. This ensures smooth and reliable power transmission and precise motion trajectory, effectively reducing vibration and errors during processing. It also ensures the consistency of hole position, depth, and angle for each drilled hole, thereby guaranteeing the final processing quality and structural strength of the badminton racket.

After adjusting the size of the elliptical trajectory, the hole processing body 3 moves along the elliptical trajectory, thereby realizing the contour processing of a specific elliptical hole system trajectory of a badminton racket.

[0036] Please see Figure 1 , Figure 2 and Figure 3This invention provides a badminton racket drilling machine. The main body 1 includes a drive steering structure 11 that provides initial rotational power. A bracket 12 is rotatably wrapped around the upper side of the outer surface of the drive steering structure 11. A movable bevel gear 13 is rotatably connected to the left side inside the bracket 12. The bottom of the movable bevel gear 13 meshes with the drive steering structure 11 to convert the horizontal axis rotational motion into the vertical axis motion. A shaft 14 is provided through the middle side inside the movable bevel gear 13. A groove is provided on the left half of the rear side of the shaft 14. A protrusion is provided on the rear side inside the movable bevel gear 13. The groove inside the shaft 14 is slidably connected to the protrusion to transmit power and allow axial sliding to adapt to changes in the trajectory diameter.

[0037] A shaft 14 is inserted through the middle of the bracket 12 to provide stable support. The right side of the shaft 14 is inserted through the inside of the support frame 15. The right end of the shaft 14 is fixed to the first bevel gear 16, transmitting the rotational power of the shaft 14 to the first bevel gear 16 and driving the first bevel gear 16 to rotate. A rectangular rod 17 is inserted through the upper side of the inside of the bracket 12, and the top right side of the bracket 12 is fastened to the rectangular rod 17 by a fastening bolt 121. The right end of the rectangular rod 17 is fixed to the support frame 15 so as to adjust the lateral position of the support frame 15, change the size of the elliptical trajectory, and lock it firmly after the position is adjusted to ensure the stability of the processing.

The power transmission direction is changed again through the cooperation of the first bevel gear 16 and the second bevel gear 18, and the motion is transmitted to the output column 19. The top side of the column 19 rotates through the top of the support frame 15, and the top part of the column 19 is connected to the track shifting body 2, so as to transmit the motion trajectory generated by the support shifting body 1 to the track shifting body 2. Through the cooperation of the two, an elliptical motion trajectory is formed and acts on the hole processing body 3.

[0039] The drive steering structure 11 includes a housing 111. A first motor 112 is locked and fixed inside the rear right side of the housing 111. The output shaft of the first motor 112 is connected to a worm gear 113, and the front part of the worm gear 113 is inserted into and rotates inside a washer 114. The washer 114 is fixedly connected to the right side inside the housing 111. A worm wheel 115 is meshed and driven on the left side of the worm gear 113. The first motor 112 is used as a power source to transmit power to the worm wheel 115. A sleeve 116 is fixed through the middle side of the worm wheel 115 to directly output the rotational motion of the worm wheel 115. The sleeve 116 rotates through the middle side of the top of the housing 111, and the top of the sleeve 116 is fixed to the bracket 12 to transmit power to the bracket 12 to drive its rotation.

[0040] An annular protrusion is provided on the lower middle side of the outer surface of the sleeve 116. The annular protrusion is inserted into and rotates inside the annular frame 117 to form axial positioning. The top side of the annular frame 117 is fixed to the bin seat 111. While achieving axial positioning, the sleeve 116 is allowed to rotate freely, reducing friction. A column rod 118 is rotatably inserted through the middle side of the inner side of the sleeve 116. The bottom of the column rod 118 is fixed to the bin seat 111, and a fixed bevel gear 119 is fixedly connected to the top of the column rod 118. The top of the column rod 118 is rotatably inserted through the middle side of the bottom of the support 12. The top left side of the fixed bevel gear 119 meshes with the movable bevel gear 13 to provide a central guide for the rotation of the support 12, ensuring its stable rotation around the column rod 118, thereby converting the support 12 of the support into the additional rotation of the movable bevel gear 13.

[0041] Please see Figure 1 and Figure 4 This invention provides a badminton racket drilling machine. The track shifting body 2 includes a support frame 21 that acts as a support and bridge. Vertical rods 22 are fixed to the left and right sides of the top of the support frame 21. Sliding sleeves 23 are slidably connected to the outer surfaces of the two vertical rods 22. A crossbar frame 24 slides through the top front and rear sides of the sliding sleeves 23, allowing the crossbar frame 24 to slide in the left-right and front-back directions. The bottom right side of the crossbar frame 24 is fixed to the hole processing body 3 to transmit motion to the hole processing body 3. An internally threaded support block 25 is rotatably connected to the bottom left side of the crossbar frame 24. The internally threaded support block 25 is slidably connected to the inner side of the top of the slot seat 26, and the internal thread... The threaded support block 25 is connected to a lead screw 27 through the middle thread. The lead screw 27 rotates through the upper left side of the slot seat 26, converting the rotational motion of the lead screw 27 into the lateral linear motion of the threaded support block 25. The bottom left side of the slot seat 26 is connected to the support body 1 through the support head 28. The support head 28 receives power from the support body 1, and the position of the support head 28 is misaligned with the threaded support block 25. Under the action of the rotation and revolution of the power output of the support body 1, the threaded support block 25 drives the crossbar frame 24 to drive the hole processing body 3 at its right end to perform an elliptical motion trajectory, so as to realize the contour processing of the badminton racket.

[0042] Please see Figure 1 , Figure 5 , Figure 6 and Figure 7This invention provides a badminton racket drilling machine. The hole processing body 3 includes a carrier plate 31 fixed to the top left side of the track shifting body 2. A protective sleeve 32 is fixed through the middle side of the carrier plate 31. A threaded upright rod 34 is rotatably inserted through the protective sleeve 32. A turntable 33 is locked and fixed at the top of the threaded upright rod 34. The threaded upright rod 34 is threadedly connected to the top middle side of the hollow cylinder 35. By rotating the turntable 33, the rotational motion of the threaded upright rod 34 is converted into linear feed motion. Guide posts 36 slide through the top left and right sides of the hollow cylinder 35. The tops of the two guide posts 36 are fixed to the carrier plate 31. The guide posts 36 play a limiting and guiding role. A drilling structure 37 is locked and fixed at the bottom of the hollow cylinder 35 to change the vertical height of the drilling structure 37, thereby better aligning it with the hole to be processed and ensuring the drilling effect on the badminton racket.

[0043] The drilling structure 37 includes a support plate 371 locked and fixed to the bottom of the hollow cylinder 35. A second motor 372 is locked and fixed to the left side of the bottom of the support plate 371. The output shaft of the second motor 372 is connected to a drive gear 373. The right side of the drive gear 373 meshes with a driven gear ring 374. The left and right sides of the driven gear ring 374 are locked and fixed to the push-position drilling assembly 375. A positioning post 376 is fixed to the top center of the push-position drilling assembly 375. The top of the positioning post 376 rotates through the center of the support plate 371 to provide rotational support. Under the action of the second motor 372, the drive gear 373 rotates horizontally through the driven gear ring 374, thereby changing its position angle to adapt to different drilling angle requirements of the badminton racket to be processed.

[0044] The push-position drilling assembly 375 includes a rectangular housing 3751 that is locked and fixed to the left and right sides of the top and driven gear ring 374. A third motor 3752 is locked and installed on the right side inside the rectangular housing 3751. The third motor 3752 provides power for the drill bit 37510 to feed laterally. The output shaft on the left side of the third motor 3752 is connected to a threaded crossbar 3753, and the left end of the threaded crossbar 3753 is rotatably connected to the rectangular housing 3751. Two bearing blocks 3754 are wrapped around the right side of the outer surface of the threaded crossbar 3753, and the top of the two bearing blocks 3754 is fixed to the rectangular housing 3751, providing additional stable support for the threaded crossbar 3753, improving its rigidity and rotational accuracy, and enabling the threaded crossbar 3753 to rotate stably under the action of the third motor 3752.

[0045] A displacement block 3755 is threadedly connected to the left side of the outer surface of the threaded crossbar 3753, converting the rotational motion of the threaded crossbar 3753 into the linear movement of the displacement block 3755 itself. A slider 3756 is fixed to the bottom of the displacement block 3755. Slide rods 3757 are installed through the front and rear sides of the slider 3756. The left and right sides of the two slide rods 3757 are fixed to the rectangular housing 3751. The cooperation between the slide rods 3757 and the slider 3756 provides guidance for the movement of the displacement block 3755 and prevents its rotation. A protective cover 3758 is locked to the bottom of the slider 3756. A second... The system has four motors 3759, with a drill bit 37510 connected to the left output end of the fourth motor 3759. The protective cover 3758 moves laterally along with the slider 3756. When the fourth motor 3759 drives the drill bit 35710 to rotate at high speed, the drill bit 35710 is inserted into the position to be processed for drilling through the lateral movement of the protective cover 3758. A T-slot is laterally opened on the top side inside the rectangular housing 3751, and the top of the shift block 3755 slides into the T-slot, forming an additional guiding and anti-tipping structure to ensure that the shift block 3755 moves more smoothly and will not get stuck or flip over.

[0046] This invention also provides a method for using a badminton racket drilling machine. Using the aforementioned badminton racket drilling machine, the badminton racket is first placed horizontally on a processing platform, and a clamping device is used to clamp and fix the racket frame, ensuring the elliptical structure of the frame remains stable and the processing area is unobstructed. Then, the aforementioned badminton racket drilling machine is installed on the processing platform for drilling operations. The specific steps are as follows:

[0047] First, according to the shape and size of the badminton racket to be drilled, loosen the fastening bolt 121 on the bracket 12, move the rectangular rod 17 laterally to drive the support frame 15 and the entire track shifting body 2 to move relative to the bracket 12, thereby adjusting the major axis dimension of the elliptical trajectory. After adjustment, tighten the fastening bolt 121 again, and then manually rotate the lead screw 27 to drive the internal thread support block 25 to move along the slot seat 26, thereby driving the crossbar frame 24 and the hole processing body 3 to move relative to the upright frame 21, thereby adjusting the minor axis dimension of the elliptical trajectory. Through the above adjustment, the subsequent elliptical motion trajectory of the hole processing body 3 is limited 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 corresponds to the preset height position of the hole to be processed on the inner side of the badminton racket frame.

[0049] Third, the first motor 112 of the start-up drive steering structure 11 drives the sleeve 116 and the bracket 12 to revolve around the axis of the column rod 18 through the meshing of the worm gear 113 and the worm wheel 115. At the same time, through the meshing of the fixed bevel gear 119 and the movable bevel gear 13, the revolution of the bracket 12 is converted into the rotation of the movable bevel gear 13. The power is transmitted to the first bevel gear 16 through the shaft 14, and then drives the column 19 to rotate through the second bevel gear 18. The revolution of the bracket 12 and the rotation of the movable bevel gear 13 are combined, and through the track shifting body 2, the hole processing body 3 and the drill bit 37510 on it are finally driven to generate a stable, parameter-adjustable elliptical motion trajectory. By controlling the start and stop of the first motor 112, the drill bit 37510 moves along the elliptical trajectory and is accurately positioned to the center of the first hole to be processed.

[0050] Fourth, start the second motor 372 of the drilling structure 37 to drive the drive gear 373 to rotate. Through meshing with the driven gear ring 374, the entire push-position drilling assembly 375 is driven to rotate horizontally around the axis of the positioning column 376 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, start the fourth motor 3759 to drive the drill bit 37510 to rotate at high speed, and then drive the thread crossbar 3753 to rotate. Under the guidance of the slide bar 3757 and the anti-tipping protection of the T-slot, the shift block 3755 drives the drill bit 37510 to move radially towards the badminton racket frame until the drill bit 37510 completes the drilling of the hole. After the drilling is completed, control the third motor 3752 to reverse, so that the shift block 3755 drives the drill bit 37510 to move radially back to the initial safe position.

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

[0053] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
