Description

Technical Field

[0001] This utility model relates to the field of milling cutter technology, specifically to a milling cutter that is easy to install. Background Technology

[0002] A milling cutter, a rotating cutting tool with one or more cutting teeth, is used for milling operations. It is mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces, and has a wide range of applications.

[0003] Currently, in practical use, existing technologies typically employ a combination of a tool holder and a tool handle to clamp and mount the milling cutter to ensure stable operation. However, existing milling cutters have smooth surfaces, and during milling, each tooth intermittently removes the workpiece's allowance to ensure machining quality. Consequently, the overall structure is subjected to significant pressure, leading to loosening and slippage between the milling cutter and the tool holder, resulting in a higher rate of defective products. Furthermore, the length of milling cutters is mostly fixed, which cannot meet the milling requirements of some workpieces with significant structural depth. Therefore, to address the problems existing with current milling cutters, the applicant seeks to provide a milling cutter that is easy to install. Utility Model Content

[0025] 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.

[0026] Please see Figures 1-7 A milling cutter that is easy to install includes a milling cutter shank section 1, a milling section 2 at the bottom of the milling cutter shank section 1, a composite cylinder component 4 slidably mounted on the top surface of the milling cutter shank section 1, and a friction groove on the surface of the composite cylinder component 4. The friction groove is provided in no fewer than two and is equidistantly arranged along the circumference of the cylinder body 41. The friction groove penetrates the surface of the cylinder body 41, thereby fully ensuring the connection strength of subsequent clamping friction. A number of positioning holes 5 are provided on the inner wall of the composite cylinder component 4 along the longitudinal direction of its own structure.

[0027] The top surface of the milling cutter shank section 1 is provided with a T-shaped groove 3. The composite cylindrical component 4 includes a cylindrical body 41. The inner wall of the cylindrical body 41 is fixed with a slide rail 42 that is engaged inside the T-shaped groove 3. Several positioning holes 5 are equidistantly opened in the middle of the slide rail 42 and are all through-holes, thereby providing positioning support for the subsequent adjustment of the combined structure length between the milling cutter shank section 1 and the composite cylindrical component 4.

[0028] The cylindrical body 41 and the milling cutter rod section 1 are made of the same metal material, thereby ensuring the structural strength of the overall device. Furthermore, the surface of the cylindrical body 41 and the surface of the milling cutter rod section 1 are set on the same plane, ensuring the convenient clamping and installation of the overall structure.

[0029] The top of the milling cutter body section 1 is provided with a composite I-shaped groove 6 and a through hole. The through hole is spatially connected with the composite I-shaped groove 6. A limit component 7 is installed inside the composite I-shaped groove 6.

[0030] The inner wall of the middle part of the composite I-shaped groove 6 is provided with internal threads. The limiting component 7 includes a top-pressing bolt 71, a limiting rod 72, and a spring 73. The two ends of the top-pressing bolt 71 are respectively fitted into the temporal part of the composite I-shaped groove 6 and engaged in the through hole. The two ends of the spring 73 are respectively fixed to the surface of one end of the limiting rod 72 and the inner wall of the composite I-shaped groove 6. During the process of the threaded connection between one end of the top-pressing bolt 71 and the inner wall of the middle part of the composite I-shaped groove 6, it can synchronously press the transmission limiting rod 72, so that the other end of the limiting rod 72 passes through the through hole and is engaged in the corresponding positioning hole 5.

[0031] The limiting rod 72 adopts a T-shaped structure, which can meet the anti-detachment effect of reciprocating movement. The limiting rod 72 is fitted inside the composite I-shaped groove 6 and the end is set with a hemispherical structure, which facilitates pressure transmission and meets the displacement adjustment requirements.

[0032] The inner wall of the T-shaped slide 3 is provided with several positioning screw holes 8, and the several positioning screw holes 8 correspond one-to-one with several positioning holes 5. The positioning screw holes 8 away from the limiting component 7 are fitted with limiting screws 9, and one end of the limiting screw 9 can pass through the positioning hole 5 and be threaded into the corresponding positioning screw hole 8, thereby locking and limiting the end mill shank section 1 and the composite cylinder component 4. This further improves the assembly connection strength between the end mill shank section 1 and the composite cylinder component 4. The surface of the cylinder body 41 is provided with a clearance slide that can be fitted with the limiting screw 9, and the limiting screw 9 can be completely fitted into the clearance slide, thereby avoiding structural interference of the limiting screw 9 during subsequent clamping and installation.

[0033] Example 1

[0034] When in use, for high-intensity milling of the milling cutter rod section 1, the composite cylinder component 4 is assembled with the milling cutter rod section 1. Specifically, the slide rail 42 inside the composite cylinder component 4 is engaged and guided with the T-shaped slide groove 3 on the surface of the milling cutter rod section 1, so as to achieve high-precision installation of the composite cylinder component 4 and the milling cutter rod section 1.

[0035] After the milling cutter rod section 1 and the composite cylinder component 4 are assembled, the top pressure bolt 71 is screwed into the internal thread of the inner wall of the composite I-shaped groove 6. Then, the top pressure bolt 71 is used to press the transmission limit rod 72, so that the limit rod 72 passes through the corresponding through hole and is then locked into the corresponding positioning hole 5, thereby locking and limiting the combination of the composite cylinder component 4 and the milling cutter rod section 1.

[0036] Next, the multiple limit screws 9 are sequentially fitted with the remaining multiple positioning holes 5 and then threaded into the corresponding multiple positioning screw holes 8, thereby achieving double locking of the assembly of the milling cutter shank section 1 and the composite cylinder component 4.

[0037] After the milling cutter shank section 1 and the composite cylinder component 4 are fully assembled, the milling cutter shank section 1 and the composite cylinder component 4 will form a complete cutter body structure. After subsequent assembly with the existing tool holder and tool handle, the several friction grooves set on the surface of the composite cylinder component 4 can fully ensure the connection strength with the tool holder and tool handle, as well as ensure its subsequent compressive strength.

[0038] Example 2

[0039] For workpieces requiring large milling depth, multiple limit screws 9 and top bolts 71 are loosened and removed. Then, the limit rod 72 is reset under the action of the corresponding spring 73, releasing the locking limit on the internal positioning hole 5 of the composite cylinder component 4. The composite cylinder component 4 is moved, and the sliding rail 42 and the T-shaped sliding groove 3 provide guidance until the overall length of the cylinder body 41 and the milling cutter rod section 1 and the milling cutter section 2 assembly meets the usage requirements. The single movement distance is based on the distance between two adjacent positioning holes 5.

[0040] After length adjustment, the top pressure bolt 71 is screwed into the internal thread of the inner wall of the middle part of the composite I-shaped groove 6. Then, the top pressure bolt 71 is used to squeeze the transmission limit rod 72, so that the limit rod 72 passes through the corresponding through hole and is then locked into the corresponding positioning hole 5, thereby locking and limiting the combination of the composite cylinder component 4 and the milling cutter rod section 1.

[0041] Next, the multiple limit screws 9 are sequentially fitted with the remaining multiple positioning holes 5 and then threaded into the corresponding multiple positioning screw holes 8, thereby achieving double locking of the assembly of the milling cutter shank section 1 and the composite cylinder component 4.

[0042] After the milling cutter shank section 1 and the composite cylinder component 4 are fully assembled, the milling cutter shank section 1 and the composite cylinder component 4 will form a complete cutter body structure. After subsequent assembly with the existing tool holder and tool handle, the several friction grooves set on the surface of the composite cylinder component 4 can fully ensure the connection strength with the tool holder and the subsequent compressive strength of the component itself. At the same time, the overall length of the cylinder body 41 and the combination of the milling cutter shank section 1 and the milling section 2 meets the usage requirements.
