[0040] Reference Figures 1 to 8, which is the first embodiment of the present utility model, proposes an angle punching tool for punching operations in a specific area of ​​a cutter disc 1, including a base 2, the base 2 having a mounting seat 201, the cutter disc 1 vertically slidingly set on the mounting seat 201, the lower surface of the cutter disc 1 abuts against the upper surface of the base 2; the punching disc 3 is slidably set on the mounting seat 201, the lower surface of the punching disc 3 abuts against the upper surface of the cutter disc 1, and the punching disc 3 has a target hole position 301; the scale plate 4 is rotatably set on the punching disc 3, the scale plate 4 has an extension portion 401, and the extension portion 401 abuts against the reference of the tip of the cutter disc 1.

[0041] In this embodiment, in order to solve the problem of inconvenience in punching holes within a specific radius area of ​​the cutter disc in the related art, an angle punching tool is designed. First, a base 2 with a stable mounting seat 201 is created. This base 2 is made of high-strength metal material to ensure that it will not deform during long-term use. The cutter disc 1 to be processed is accurately slid and installed along the specially designed vertical slide on the mounting seat 201, so that the lower surface of the cutter disc 1 and the upper surface of the base 2 are tightly and evenly abutted. Next, the punching disc 3 is smoothly slid along the slide of the mounting seat 201 and set on the mounting seat 201, so that the lower surface of the punching disc 3 and the upper surface of the cutter disc 1 are fully abutted. During the manufacturing process of the punching disc 3, its dimensional accuracy is strictly controlled to ensure that the position of the target hole 301 is accurate. Finally, the scale disc 4 is rotatably installed on the punching disc 3, and the extension 401 of the scale disc 4 is tightly abutted against the blade tip reference of the cutter disc 1. The scale on the scale disc 4 is clear and precise, and can provide the operator with an intuitive and accurate angle reference.

[0042] The advantage is that this design and high-precision fit significantly improve the connection stability and positional accuracy between the cutter disc 1, punch disc 3, and scale disc 4. This provides an extremely stable foundation for subsequent punching operations, effectively preventing deviations caused by equipment vibration or inaccurate component fit, thereby significantly improving punching accuracy and efficiency. In mass production, this ensures highly consistent punching quality across each cutter disc 1, significantly increasing product qualification rate and reliability.

[0043] Furthermore, the scale plate 4 has an arc-shaped slot 402 and also includes a fastener 5. The fastener 5 is arranged on the punch plate 3 and located in the arc-shaped slot 402 for fixing the relative position of the punch plate 3 and the scale plate 4.

[0044] In this embodiment, the scale plate 4 is designed with a curved slot 402. A fastener 5 is installed at a suitable location on the punch plate 3. To adjust the relative position of the punch plate 3 and the scale plate 4 according to specific punching requirements, the operator simply loosens the fastener 5. The punch plate 3 can now slide freely and smoothly along the curved slot 402 to the desired precise angle. After adjustment, the fastener 5 is securely tightened to precisely fix the relative position of the punch plate 3 and the scale plate 4.

[0045] The advantage is that this design allows the tooling to flexibly and conveniently adjust the drilling angle, not only meeting the needs of drilling at various angles, but also being simple to operate and easy to master. This greatly increases the versatility and practicality of the tooling, making it suitable for drilling operations with a variety of cutterheads of different specifications and requirements, reducing the company's production costs and equipment investment.

[0046] Furthermore, the mounting seat 201 has a first groove 2011, a first snap-fit ​​groove 2012 is provided in the first groove 2011, the punching plate 3 has a first insertion portion 302, the first insertion portion 302 is vertically slidably arranged in the first groove 2011, the first insertion portion 302 has a second groove 3021, and also includes a sliding block 6, the sliding block 6 is horizontally slidably arranged in the second groove 3021, and one end extends out of the first insertion portion 302, after the sliding block 6 slides, one end of the sliding block 6 abuts or releases the abutment with the first snap-fit ​​groove 2012.

[0047] In this embodiment, a first engaging groove 2012 is precisely machined inside the first groove 2011 of the mounting base 201. The size and shape of this engaging groove are strictly designed to ensure a tight and reliable fit with the sliding block 6. The first insertion portion 302 of the punching disk 3 adopts a shape and size that matches the first groove 2011, so that it can be vertically slidably installed in the first groove 2011, and the sliding process is smooth and without jamming. Inside the first insertion portion 302, a second groove 3021 is provided for accommodating the sliding block 6, one end of which can flexibly extend out of the first insertion portion 302. When the punching disk 3 needs to be fixed, the sliding block 6 is pushed so that one end thereof is tightly abutted against the first engaging groove 2012, thereby achieving a firm fixation of the punching disk 3. When the punching disk 3 needs to be moved, the abutment can be released by the reverse operation.

[0048] The advantage is that this structural design allows the punching disc 3 to be stable when it needs to be fixed and will not be displaced by external forces, thereby effectively ensuring the accuracy and quality of the punching. When the position needs to be adjusted, the operation can be completed easily and quickly, greatly improving work efficiency and operational convenience.

[0049] Furthermore, a guide column 3022 is provided in the second groove 3021, a first abutting surface 601 is provided in the middle of the sliding block 6, and a sliding rod 7 is also included. The sliding rod 7 is vertically slidably arranged on the guide column 3022, and the sliding rod 7 abuts against the first abutting surface 601 near one end of the sliding block 6. The vertical sliding of the sliding rod 7 drives the sliding block 6 to slide horizontally.

[0050] In this embodiment, a guide post 3022 is precisely mounted within the second groove 3021. A first abutment surface 601 is designed in the middle of the sliding block 6. The angle and shape of the first abutment surface 601 are carefully calculated to ensure good contact and smooth force transmission with the sliding rod 7. The sliding rod 7 is mounted on the guide post 3022 via a sliding fit, allowing the sliding rod 7 to slide vertically along the guide post 3022. The end of the sliding rod 7 closest to the sliding block 6 is tightly fitted with the first abutment surface 601, allowing the sliding block 6 to slide horizontally with precision and stability during the vertical sliding of the sliding rod 7.

[0051] The advantage is that the precise cooperation between the sliding rod 7 and the guide column 3022 realizes extremely precise control of the sliding of the sliding block 6. It avoids sliding errors caused by improper operation or insufficient equipment precision, and greatly improves the operating accuracy and stability of the tooling.

[0052] Furthermore, it also includes an elastic member 8, both ends of which are respectively connected to the end of the sliding block 6 away from the first clamping groove 2012 and the first insertion portion 302, for providing a force to release the abutment between one end of the sliding block 6 and the first clamping groove 2012.

[0053] In this embodiment, an elastic member 8 with excellent installation performance is installed, and both ends of the elastic member 8 are respectively connected to an end of the sliding block 6 away from the first engaging groove 2012 and the first inserting portion 302 .

[0054] The advantage is that when the punch plate 3 needs to be released, the elastic member 8 can quickly and automatically help the sliding block 6 to return to its original position, greatly saving the operator's operation time and energy. In addition, the presence of the elastic member 8 can also reduce equipment damage caused by improper human operation, extend the service life of the tooling, and reduce the maintenance cost and frequency of the equipment.

[0055] Furthermore, the sliding rod 7 has a second snap-in groove 701 at one end away from the sliding block 6, and also includes a limiting rod 9, both ends of which are hinged to the punching disk 3. After one end of the sliding block 6 abuts against the first snap-in groove 2012, the middle part of the limiting rod 9 is located in the second snap-in groove 701, which is used to limit the relative position of the sliding rod 7 and the punching disk 3.

[0056] In this embodiment, a second engaging groove 701 is machined at the end of the sliding rod 7 away from the sliding block 6. The size and shape of this engaging groove have been strictly designed and tested to ensure accurate cooperation with the limiting rod 9. The two ends of the limiting rod 9 are connected to the punching disk 3 through a hinge structure. The hinge structure adopts high-quality pins and bearings to ensure the flexibility and stability of the rotation of the limiting rod 9. When one end of the sliding block 6 abuts against the first engaging groove 2012 and the punching disk 3 is fixed, the middle part of the limiting rod 9 is placed in the second engaging groove 701, thereby effectively limiting the relative position of the sliding rod 7 and the punching disk 3 and preventing the sliding rod 7 from sliding in the opposite direction.

[0057] The advantage is that it can reliably prevent the sliding rod 7 from accidentally moving during operation, providing double protection for the punch plate 3 in a fixed state, and further enhancing the stability of the punch plate 3. This significantly improves the punching accuracy, especially in long-term, high-intensity working environments, and can effectively avoid punching errors caused by loose components, ensuring the stability and reliability of product quality.

[0058] Furthermore, it also includes a reference block 10, which is horizontally slidably arranged on the extension part 401, and the scale plate 4 is in contact with the cutting edge of the cutter head 1 through the reference block 10.

[0059] In this embodiment, a high-precision horizontal slide is designed on the extension portion 401 of the scale plate 4 for horizontally sliding installation of the reference block 10. The reference block 10 is made of a material with high hardness and good wear resistance and is finely processed to make its surface smooth and flat. In order to ensure the accuracy of the reference block 10 and the cutting tip of the cutter disc 1, a precision-ground abutment surface is provided at the front end of the reference block 10. The scale plate 4 is in contact with the cutting tip of the cutter disc 1 through this adjustable reference block 10. The operator can fine-tune the position of the reference block 10 according to actual needs to obtain the most accurate abutment effect.

[0060] The advantage is that the presence of reference block 10 ensures a more precise and reliable contact between scale plate 4 and the cutting tip of cutter disc 1. This effectively prevents angular deviations caused by inaccurate contact during the drilling process, further improving the accuracy and consistency of drilling angles. For drilling operations requiring extremely high precision, this design can significantly improve product quality and performance.

[0061] Furthermore, the base 2 also has a clearance groove 202 , which is arranged directly below the target hole position 301 .

[0062] In this embodiment, the design of the base 2 takes into full consideration the issue of waste removal during drilling. A spacious clearance groove 202 is specifically provided on the base 2 directly below the target hole location 301. The shape and size of the clearance groove 202 are optimized to accommodate a large amount of waste, preventing waste accumulation from interfering with the drilling operation. To facilitate waste removal, the inner wall of the clearance groove 202 is smoothed to reduce waste adhesion.

[0063] Advantageously, the design of the clearance groove 202 effectively prevents waste accumulation and blockage during the drilling process, ensuring smooth drilling. This reduces production interruptions caused by untimely waste removal and improves production efficiency. Furthermore, the smooth inner wall design makes waste removal more convenient and quick, reducing operator labor intensity and working time.
