Description

Technical Field

[0001] The utility model relates to the field of milling cutters, in particular to a high-strength milling cutter. Background Technique

[0002] A milling cutter is a commonly used cutting tool for milling operations. It is mainly used in machining to remove excess material from the surface of a workpiece by a rotating cutter to achieve the required shape and size. There are many types of milling cutters, such as face milling cutters, end mills, ball nose milling cutters, chamfer milling cutters, etc. Different types of milling cutters are suitable for different machining requirements and materials. The existing milling cutters have a single structure. When the milling cutter head contacts the workpiece surface for work, the internal structure of the milling cutter head is constantly squeezed. A slight vibration will cause damage to the structure of the milling cutter head, resulting in the fragmentation of the milling cutter head and affecting its service life.

[0003] Therefore, it is necessary to provide a high-strength milling cutter to solve the above technical problems. Summary of the Utility Model

[0004] The utility model provides a high-strength milling cutter, which solves the problems that the existing milling cutter has a single structure, and when the milling cutter head contacts the workpiece surface for work, the internal structure of the milling cutter head is constantly squeezed, a slight vibration will cause damage to the structure of the milling cutter head, resulting in the fragmentation of the milling cutter head and affecting its service life.

[0005] To solve the above technical problems, a high-strength milling cutter provided by the utility model includes a fixed rod. The top end of the fixed rod is fixed with a milling cutter head, and a milling cutter edge is fixed on the milling cutter head. A chute corresponding to the milling cutter head is provided on the fixed rod;

[0006] A fixed frame is clamped on the milling cutter head, and the fixed frame is fixed to the milling cutter head by screws. A first limit block and a second limit block are respectively fixed on the fixed frame. A screw rod passes through the first limit block, and the screw rod is threadedly connected to the second limit block. A through hole adapted to the screw rod is provided on the fixed rod.

[0007] Preferably, a card slot adapted to the second limit block is provided at the top end of the fixed rod, and a limit groove adapted to the first limit block is provided on the fixed rod.

[0008] Preferably, screw holes adapted to the screws are provided on both the fixed frame and the milling cutter head.

[0009] Preferably, a stable groove is provided on the fixed rod.

[0010] Preferably, a mounting groove is provided on the fixed rod.

[0011] Preferably, a fixing groove adapted to the fixed frame is provided on the milling cutter head.

[0012] Compared with the related technologies, the high-strength milling cutter provided by the present utility model has the following beneficial effects:

[0013] The present utility model provides a high-strength milling cutter. By sleeving a fixing frame on the surface of the milling cutter head and fixing it with screws and threads, the fixing frame provides stress protection for the milling cutter head, preventing the milling cutter head from being extruded and deformed. The fixing frame also acts as a barrier to prevent the vibration amplitude of the milling cutter head from being too large. This solves the problems of the existing milling cutter having a single mechanism, and when the milling cutter head contacts the workpiece surface for work, the internal structure of the milling cutter head has been continuously extruded, and slight vibration will cause damage to the structure of the milling cutter head, resulting in the fragmentation of the milling cutter head and affecting its service life.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0021] Please refer to Figures 1-5 shown. A high-strength milling cutter includes a fixing rod 1. The top end of the fixing rod 1 is fixed with a milling cutter head 2, and a milling cutter edge 3 is fixed on the milling cutter head 2. A chute 4 corresponding to the milling cutter head 2 is provided on the fixing rod 1 to facilitate the sliding of waste chips;

[0022] A fixing frame 5 is clamped on the milling cutter head 2 of the utility model, and the fixing frame 5 is fixed to the milling cutter head 2 by screws 6. A first limiting block 7 and a second limiting block 8 are respectively fixed on the fixing frame 5. A screw rod 9 penetrates through the first limiting block 7, and the screw rod 9 is in threaded connection with the second limiting block 8. A through hole 10 adapted to the screw rod 9 is provided on the fixing rod 1, which improves the fixing stability of the fixing frame 5. The fixing frame 5 is fixed by the screws 6 and 8 in a threaded manner, so that the fixing frame 5 provides stress protection for the milling cutter head 2 and prevents the milling cutter head 2 from being extruded and deformed.
