[0020] 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. Example 1

[0021] like Figures 1 to 4 As shown, a high-strength replaceable end mill includes a fixed base 1, a support rod 2, a transmission rod 3, an end mill 4, a workpiece support 5, and a linkage mechanism 6. The support rod 2 is slidably connected to one end of the fixed base 1, the transmission rod 3 is rotatably connected to the top end of the support rod 2, the end mill 4 is coaxially connected to one end of the transmission rod 3, and the workpiece support 5 is rotatably connected to the other end of the fixed base 1.

[0022] The linkage mechanism 6 is mounted on the fixed base 1 and includes an active turntable 61, a driven turntable 62, a linkage belt 63, a passive disc 64, an adjusting rod 65, and a slide groove 66. The active turntable 61 is rotatably connected to the fixed base 1 on the side near the workpiece support 5, and the driven turntable 62 is rotatably connected to the fixed base 1 on the side near the support rod 2. The linkage belt 63 is located between the active turntable 61 and the driven turntable 62. The passive disc 64 is coaxially fixed with the driven turntable 62. The adjusting rod 65 is located at the edge of the passive disc 64. The slide groove 66 passes through the support rod 2, and the adjusting rod 65 is slidably engaged in the slide groove 66.

[0023] The linkage mechanism 6 also includes a driving bevel gear 67, a docking rod 68, and a driven bevel gear 69. The driving bevel gear 67 is coaxially fixed on one side of the driving turntable 61. The docking rod 68 is rotatably connected in the fixed seat 1. One end of the docking rod 68 is coaxially fixed with the workpiece support seat 5, and the other end is coaxially fixed with the driven bevel gear 69. The driven bevel gear 69 meshes with the driving bevel gear 67.

[0024] In this utility model, by setting a linkage mechanism 6, the driven turntable 62 can rotate synchronously with the active turntable 61 through the linkage belt 63, and drive the passive turntable 64 to rotate, thereby driving the adjusting rod 65 to move in linkage. The adjusting rod 65 slides in the slide groove 66, thereby allowing the support rod 2 to slide back and forth in the fixed seat 1, thereby driving the flat end mill 4 to move up and down in reciprocating motion. At the same time, the active bevel gear 67 drives the driven bevel gear 69 to mesh and move in linkage, thereby driving the workpiece support seat 5 to rotate, so that the flat end mill 4 can mill a cam structure at the edge of the workpiece. This is simple and efficient, and also effectively reduces the production and processing costs. Example 2

[0025] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0026] Both the active turntable 61 and the driven turntable 62 have arc-shaped grooves on their outer walls. The linkage belt 63 is engaged in the arc-shaped grooves, which limit the linkage belt 63 and prevent it from slipping.

[0027] The grooves on the outer walls of the active turntable 61 and the driven turntable 62, as well as the inner wall of the linkage belt 63, are all frosted. The frosted surface increases the friction of the linkage belt 63, preventing it from slipping during linkage.

[0028] The adjusting rod 65 is externally fitted with a rotating cylinder, which rolls against the slide groove 66. The rotation of the rotating cylinder reduces the wear of the adjusting rod 65.

[0029] A sleeve is coaxially fixed to one end of the transmission rod 3 near the flat end mill 4. The flat end mill 4 is mated inside the sleeve and is detachably connected by screws. The sleeve allows the flat end mill 4 to be disassembled and replaced according to the actual situation.

[0030] Working principle: When using this flat end mill, first fix the workpiece to be milled on the workpiece support 5. Then, drive the active turntable 61 to rotate through the external transmission mechanism, and drive the driven turntable 62 to rotate synchronously with the active turntable 61 through the linkage belt 63. This drives the passive turntable 64 to rotate, causing the adjusting rod 65 to slide in the slide groove 66. This allows the support rod 2 to slide back and forth in the fixed seat 1, thereby driving the flat end mill 4 to move up and down. At the same time, the active bevel gear 67 drives the driven bevel gear 69 to mesh and move together, thereby driving the workpiece support 5 to rotate. This allows the flat end mill 4 to mill a cam structure at the edge of the workpiece.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
