Component 700: The adjustment assembly 500 includes a telescopic cylinder 501, a mounting plate 502, and a rotary cylinder 503. The telescopic cylinder 501 is fixedly connected to one side of the base plate 100. The output end of the telescopic cylinder 501 is connected to the mounting plate 502. The rotary cylinder 503 is fixedly connected to the front side of the mounting plate 502. The placement seat 600 is fixedly connected to the front side of the rotary cylinder 503. The limiting assembly 700 includes a limiting block 701, a mounting cover 702, and a spring member 703. The mounting cover 702 is fixedly connected to the front side of the placement seat 600. Three sets of spring members 703 are fixedly connected inside the mounting cover 702. The limiting block 701 extending into the placement groove 601 is fixedly connected to the spring members 703. The bottom and top of the limiting block 701 are both arc-shaped.

[0033] Substrate 100: As the main support structure, it is made of aluminum alloy and is fixed to the worktable at the bottom by bolts;

[0034] Clamping assembly 400: extends outside the mounting cylinder, drives the fastening knob 402 via servo motor 401, and drives 4 sets of guide rods 406 to move radially. The clamping head 404 adopts a rubber-coated V-shaped block to fit the curved surface of the racket.

[0035] Adjustment component 500: Telescopic cylinder 501 pushes mounting plate 502 and rotary cylinder 503; rotary cylinder 503 (90° rotation) drives placement seat 600 to switch between upper and lower placement slots 601;

[0036] Limiting component 700: The top / bottom arc radius of the limiting block 701 matches the racket shaft, and the spring 703 provides preload to ensure that the racket shaft automatically locks in after insertion.

[0037] In this embodiment, a bearing 201 that is rotatably connected to the mounting cylinder 200 is fixedly connected to the substrate 100, and a guide port 203 is provided on the front side of the mounting cylinder 200; a mounting base 101 is fixedly connected to the bottom of the substrate 100, and an assembly hole is provided on the mounting base 101.

[0038] Mounting cylinder 200: penetrates the center of the base plate and is rotatably connected by bearing 201. Four radial guide ports 203 are opened on the front.

[0039] In this embodiment, the clamping assembly 400 includes a second servo motor 401, a fastening knob 402, a guide port 403, a clamping head 404, a connecting frame 405, and a guide rod 406. The second servo motor 401 is fixedly mounted on the back of the mounting cylinder 200. The output end of the second servo motor 401 extends into the mounting cylinder 200 and is connected to the fastening knob 402. The fastening knob 402 is provided with four sets of guide ports 403. The guide rod 406 is slidably mounted on the guide port 403 through the fastening knob 402. The end of the guide rod 406 is fixedly connected to the connecting frame 405 extending out of the guide port 203. The outer end of the connecting frame 405 is fixedly connected to the clamping head 404.

[0040] The guide rod 406's movement mechanism: the guide port 403 of the fastening knob 402 is a spiral groove, which pushes the guide rod 406 to move linearly when rotated;

[0041] 404 self-adaptive clamping head: It adopts a spring-preloaded floating design that automatically and finely adjusts to fit the curved surface of the racket during clamping;

[0042] Work process: When the servo motor 401 rotates clockwise, the clamping head 404 expands outward in sync, causing the clamping head 404 to clamp and fix the racket ring.

[0043] In this embodiment, the drive assembly 300 includes a servo motor 301 and a gear 302. The servo motor 301 is fixedly installed inside the mounting cavity 102, and the gear 302 is connected to the output end of the servo motor 301. A gear ring 202 that meshes with the gear 302 is fixedly connected to the mounting cylinder 200.

[0044] Drive component 300: Servo motor 301 drives gear ring 202 through gear 302 to realize the intermittent rotation of mounting cylinder 200, rotating 6° each time to ensure that it adapts to the drilling gap;

[0045] During drilling, the servo motor 301 starts after each hole is completed, driving the racket ring to rotate to the next angle, and working with the drill bit to complete the uniform wire hole processing.

[0046] In this embodiment, the placement slots 601 are arranged facing each other, and the placement path of the placement slots 601 is consistent with the clamping point of the clamping head 404.

[0047] Alignment design of placement slots 601: The center of the two slots coincides with the clamping center of the clamping head 404 after it is unfolded, ensuring accurate positioning of the racket ring after flipping.

[0048] The placement slot 601 is equipped with a removable bushing, which is suitable for racket shafts of different thicknesses. The bushing of the placement slot 601 can be replaced to make it compatible.

[0049] Working principle and usage process of this utility model:

[0050] When in use, inspect the device and connect the electrical components on the device to the external control system. Power the device through the control system, which can be a PLC controller.

[0051] The first step involves inserting the end of the racket shaft into the placement groove 601. During insertion, the racket shaft presses against the limiting block 701, causing the limiting block 701 to compress the spring 703 until the racket shaft passes over the limiting block 701 and enters the placement groove 601, ensuring that the end of the racket shaft abuts against the inner wall of the placement groove 601. The limiting block 701, in cooperation with the placement seat 600, limits and constrains the racket shaft in the placement groove 601. Then, the rotary cylinder 503 is activated to flip the placement seat 600 upward, causing the placement groove 601 at the bottom of the placement seat 600 to switch to the top. At this time, the racket shaft in the placement groove 601 simultaneously switches to the upward, causing the racket ring to flip to the clamping area to wait for clamping and fixing. The telescopic cylinder 501 is activated again to retract the mounting plate 502, which is in the extended state before loading.

[0052] The second step is that the racket shaft has reached the clamping position, and the placement slot 601, which was originally at the top of the placement seat 600, is flipped to the bottom, waiting for personnel to replenish it;

[0053] The third step involves starting the servo motor 401 to rotate the fastening knob 402. The fastening knob 402 drives the guide rod 406 via the guide port 403. Since the connecting frame 405 is limited by the guide port 203, it will expand, causing the clamping head 404 at the end of the connecting frame 405 to expand and clamp the racket ring, thus completing the fixation. In this way, the drilling device located above the front of the racket shaft performs the drilling operation. During the drilling, the servo motor 301 is indirectly started to drive the gear 302 to rotate, thereby driving the gear ring 202. The mounting cylinder 200 is subjected to force and rotates intermittently through the bearing 201 to ensure that the drilling diameter meets the operation requirements.
