Description

Technical Field

[0001] This utility model relates to the field of tennis racket processing technology, specifically to a cutting device for hollowed-out structures on the surface of an aluminum tennis racket. Background Technology

[0002] Aluminum tennis rackets still hold a certain market share in the low-to-mid-range market due to their good strength-to-weight ratio and machinability. During manufacturing, the racket face area typically requires the machining of multiple perforations distributed along the frame's arc to reduce weight and improve swing flexibility. These perforations are mostly of regular geometric shapes, evenly distributed within the inner or outer annular area of ​​the frame, and are one of the key features of the racket's structure.

[0003] Currently, the common cutting method involves using fixed multi-head milling cutters or punches to process the racket face in one go or in segments. These devices typically integrate all cutting units onto a rigid tool holder, with non-adjustable tool positions, and can only adapt to a single model or a specific curvature of the racket frame structure. When changing to different specifications of tennis rackets, the existing tools cannot match the new hole distribution due to differences in the radius of curvature and the distribution of perforations in each model's frame. This necessitates redesigning or replacing the entire tool holder assembly, increasing production costs, extending changeover and debugging time, and exhibiting poor versatility, making it difficult to meet the flexible production needs of small batches and multiple varieties. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device for the hollow structure of aluminum tennis racket face, so as to solve the problems mentioned in the background art, which are that the current cutting device uses a fixed rigid cutter seat, resulting in the inability to adjust the cutter position, difficulty in adapting to the curvature and hollow hole distribution of different racket frames, high replacement cost, and poor versatility.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for the hollow structure of an aluminum tennis racket face, comprising a processing table, a cutting base mounted on the top of the processing table via a lifting drive mechanism, an adjusting guide plate mounted on the bottom of the cutting base via a snap-fit ​​clamping structure, and a sliding channel with an arc-shaped structure at the lower end of the adjusting guide plate, wherein multiple sets of cutting module units are slidably connected within the sliding channel, each cutting module unit comprising an independent mounting base, a forming cutter detachably connected to the bottom of the independent mounting base, and a miniature drive motor embedded in the independent mounting base.

[0006] Preferably, the snap-on clamping structure includes L-shaped fixing seats disposed on both sides of the cutting base. The vertical arm of the L-shaped fixing seat is provided with a guide groove. The two sides of the adjusting guide plate are respectively provided with protrusions that match the guide grooves on the L-shaped fixing seat. The protrusions and the guide grooves on the L-shaped fixing seat cooperate to form a sliding guide, and the adjusting guide plate is pressed by fastening bolts passing through the locking holes on the L-shaped fixing seat.

[0007] Preferably, the bottom surface of the L-shaped fixing seat is provided with a plurality of positioning pin holes, and the top of the adjusting guide plate is provided with positioning pins that match the number and position of the positioning pin holes.

[0008] Preferably, the back of the adjusting guide plate is provided with multiple elastic buckles arranged in parallel, and the inside of the cutting base is provided with a corresponding fitting groove that matches the elastic buckles.

[0009] Preferably, the cross-section of the sliding channel is T-shaped, the independent mounting base is provided with a matching T-shaped slider, and the independent mounting base can be fixed to any position on the adjusting guide plate by locking screws.

[0010] Preferably, the adjusting guide plate is an integral casting with multiple reinforcing ribs arranged in an arc-shaped trajectory inside its cavity.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This aluminum tennis racket face hollow structure cutting device achieves flexible adjustment of the cutter position, adapting to different racket frame curvatures and hollow hole layouts, eliminating the need to replace the entire cutter holder, reducing production costs, and improving changeover efficiency and equipment versatility. Through the design of the arc-shaped sliding channel at the lower end of the adjusting guide plate, multiple cutting module units can freely slide and be positioned along the racket frame arc. The cooperation of independent mounting bases and locking pins enables rapid fixing of the forming cutter at any position. Combined with the snap-fit ​​clamping structure between the cutting base and the adjusting guide plate, it facilitates quick replacement of suitable guide plates according to different racket types. The overall structure achieves efficient, precise, and reconfigurable cutting operations, significantly improving the equipment's adaptability to multi-variety, small-batch production.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a cutting device for hollowed-out aluminum tennis racket face, including a processing table 1. The top of the processing table 1 is provided with a clamping and positioning seat for positioning the aluminum tennis racket face. A cutting base 2 is installed above the processing table 1 via a lifting drive mechanism. An adjusting guide plate 3 is installed at the bottom of the cutting base 2 via a snap-fit ​​clamping structure. The lower end of the adjusting guide plate 3 has an arc-shaped sliding channel 4. Multiple cutting module units 5 are slidably connected within the sliding channel 4. Each cutting module unit 5 includes an independent mounting base 51, a forming cutter 52 detachably connected to the bottom of the independent mounting base 51, and a miniature drive motor 53 embedded in the independent mounting base 51. This device uses a lifting drive mechanism to drive the cutting... The base 2 moves downwards as a whole, causing the adjusting guide plate 3 to move downwards as well. The arc-shaped sliding channel 4 at its lower end corresponds to the contour of the aluminum frame to be processed. The operator can pre-slide each group of cutting module units 5 along the arc direction in the sliding channel 4 to the required coordinates and fix them according to the distribution position of the hollow holes on the target frame. This achieves precise positioning of each group of forming tools 52 in spatial layout. Then, the micro drive motor 53 starts, driving the corresponding forming tool 52 to rotate and perform cutting operations. Multiple independently controlled cutting module units 5 simultaneously complete the hollow hole processing at different positions. Since each group of cutting module units 5 can be freely adjusted in position within the sliding channel 4 of the adjusting guide plate 3, and the adjusting guide plate 3 itself can be quickly and easily clamped by a snap-on clamping structure, the operation is seamless. The frame can be replaced to accommodate different curvatures, eliminating the need for a complete replacement of the rigid cutter head as required by traditional equipment. This significantly improves the equipment's adaptability to different tennis racket models and effectively solves the problems of high production costs, long debugging cycles, and poor versatility caused by fixed cutter positions and the need to replace the entire cutter head when changing models in existing technologies. It meets the actual needs of flexible production of small batches and multiple varieties. Meanwhile, the forming cutter 52 can be detachably mounted on the bottom of the independent mounting base 51 via a magnetic quick-change interface. The forming cutter 52 includes a round milling cutter for machining circular holes, a profile milling cutter for machining elliptical holes, or a punching cutter head. The snap-fit ​​clamping structure includes L-shaped fixing seats 21 located on both sides of the cutting base 2. The upper end of the L-shaped fixing seat 21 is attached to the cutting base 2. The connection is fixed by welding. The vertical arm of the L-shaped fixing base 21 is provided with a guide groove. The two sides of the adjusting guide plate 3 are respectively welded and fixed with protruding strips 31 that match the guide grooves on the L-shaped fixing base 21. The protruding strips 31 and the guide grooves on the L-shaped fixing base 21 cooperate to form a sliding guide. The adjusting guide plate 3 is pressed by fastening bolts 22 passing through the locking holes on the L-shaped fixing base 21. This structure achieves quick alignment and installation of the adjusting guide plate 3 through the sliding cooperation between the L-shaped fixing base 21 and the protruding strips 31. The fastening bolts 22 are used to lock and fix it, ensuring a stable connection while facilitating disassembly and replacement, thus improving the efficiency of model changeover. The bottom surface of the upper end of the L-shaped fixing base 21 is provided with several positioning pin holes 23, which are distributed in an array.

[0018] The top of the adjusting guide plate 3 is welded with positioning pins 32 that match the number and position of the positioning pin holes 23. This structure achieves precise positioning between the adjusting guide plate 3 and the cutting base 2 through the cooperation of the positioning pin holes 23 and the positioning pins 32, preventing installation misalignment and ensuring that the circumferential angle of the guide plate is consistent after each replacement. This improves the repeatability and processing consistency of the device. The back of the adjusting guide plate 3 has multiple parallel elastic buckles 33. The inner end of each elastic buckle 33 is hinged to the connection point of the adjusting guide plate 3 via a pin. The cutting base 2 has corresponding fitting grooves 24 that match the elastic buckles 33. This structure, with the cooperation of the elastic buckles 33 and the fitting grooves 24, provides auxiliary locking and anti-loosening of the adjusting guide plate 3, enhancing installation stability and preventing the guide plate from loosening and falling off due to vibration or cutting reaction force, thus improving the safety of equipment operation. For reliability, the sliding channel 4 has a "T"-shaped cross-section, and the independent mounting base 51 is equipped with a matching "T"-shaped slider. The independent mounting base 51 can be fixed to any position on the adjusting guide plate 3 by locking screws. This structure, in cooperation with the sliding channel 4 and the "T"-shaped slider, enables the cutting module unit 5 to slide smoothly on the adjusting guide plate 3 and prevents it from falling off. Combined with the locking screws, the position is locked to ensure that the forming tool 52 is firmly fixed in any set position, meeting the precise machining requirements of different hole layouts. The adjusting guide plate 3 is an integral casting, and its inner cavity is equipped with multiple reinforcing ribs 34 arranged in an arc trajectory. This structure of reinforcing ribs 34 significantly improves the structural rigidity and deformation resistance of the adjusting guide plate 3, ensuring that it can maintain its shape accuracy under long-term use and cutting vibration, and ensuring the smooth movement and machining stability of the cutting module unit 5.

[0019] Working principle: When using this aluminum tennis racket face hollowing structure cutting device, firstly, select the corresponding adjusting guide plate 3 according to the curvature of the racket frame to be processed. Slide the adjusting guide plate 3 along the guide groove of the L-shaped fixing seat 21 through the protruding strips 31 on both sides into the bottom of the cutting base 2 until the positioning pin 32 is inserted into the positioning pin hole 23 on the upper bottom surface of the L-shaped fixing seat 21. At the same time, the elastic buckle 33 on the back of the adjusting guide plate 3 is engaged into the fitting groove 24 inside the cutting base 2. Then, tighten the fastening bolt 22 to complete the fixing. Next, according to the hollowing hole of the racket face... The distribution positions are such that each group of cutting module units 5 is pushed along the arc to the corresponding coordinates in the sliding channel 4. The independent mounting base 51 is locked on the adjusting guide plate 3 by locking the locking screw. Then, the corresponding forming cutter 52 is replaced according to the hole shape requirements and installed at the bottom of the independent mounting base 51. Finally, the lifting drive mechanism is started to drive the cutting base 2 to move down, so that each forming cutter 52 is aligned with the processing area of ​​the aluminum surface. At the same time, the micro drive motor 53 is started to drive the forming cutter 52 to rotate, completing the multi-hole synchronous cutting operation of the aluminum surface, thus completing a series of tasks.

[0020] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
