[0007] The mounting groove includes a fan-shaped limiting groove and an arc relief groove. Two sides of the triangular blade respectively abut against two side walls of the fan-shaped limiting groove, and one of the cutting surfaces of the triangular blade is matched and arranged in the arc relief groove.

[0008] Preferably, the sealing groove blade and the trash groove blade are used in combination, and the left shield groove blade and the right shield groove blade are used in combination.

[0009] By adopting the above technical solutions, complex formed dimensions can be combined to meet the sealing and dust prevention requirements in specific fields.

[0010] In summary, the present application includes at least one of the following beneficial technical effects: The milling cutter structure for machining the inner groove of the brake caliper adopts the method of grinding the same triangular blade blank. The tool life is 3 times that of a single blade, and the blank procurement is convenient and the inventory is reduced. Moreover, the positioning reference for modifying the same blade is unified, reducing the difficulty of tool body machining. The blank selection of the milling cutter blades for the inner groove of this group of brake calipers is reasonable, and the manufacturing process is good, and a series of products can be formed, meeting the specified requirements of indexable milling cutter blades, and is suitable for further popularization and application.

Detailed Description of the Embodiment

[0021] The following will further describe the present application in detail Figures 1-9 with reference to the accompanying

[0022] The embodiment of the present application discloses a milling cutter structure for machining the inner groove of a brake caliper. Refer toFigures 1-9 , including a tool handle 2 and a tool tip 3. The tool tip 3 is fixed on the tool handle 2. Six mounting grooves 31 are evenly distributed along the circumferential direction on the tool tip 3. A sealing groove blade 4, a garbage groove blade 5, a left shield groove blade 6 and a right shield groove blade 7 are respectively fixed in the mounting grooves 31. Among them, three mounting grooves are provided with the sealing groove blades 4, and the three sealing groove blades 4 are evenly spaced. The sealing groove blade 4, the garbage groove blade 5, the left shield groove blade 6 and the right shield groove blade 7 are all triangular and each has three cutting surfaces.

[0023] A variety of blades are all ground and processed from the same triangular blade blank. The setting of the three cutting surfaces triples the service life of the blade compared with the existing single blade, which is convenient for purchasing the blank and reduces the inventory. Moreover, the same kind of blade has a unified repositioning reference, reducing the difficulty of tool body processing.

[0024] Refer to Figure 3 and Figure 4 , the mounting groove 31 includes a fan-shaped limiting groove 311 and an arc relief groove 312. Two side edges of the triangular blade respectively abut against two side walls of the fan-shaped limiting groove 311, and one of the cutting surfaces of the triangular blade is matched and arranged in the arc relief groove 312.
