Different tools and tool holders are also required. Moreover, the tools need to be changed frequently during the machining process. While changing tools, the machining accuracy will be reduced and more waiting time is required during the tool change process. Utility Model Content

[0009] The blade assembly consists of alternating chamfered and boring blades.

[0010] The blade has alternating chamfering and boring edges arranged towards the end.

[0011] The blade's cutting edge shape is the same as the bore wall shape of the wedge-shaped wheel cylinder bore being machined.

[0012] The bore wall shape of the wedge-shaped wheel cylinder orifice includes multiple orifice chamfers, orifice step planes, and orifice bevels; the chamfering cutting edge is used to contact and process the orifice chamfers of the wedge-shaped wheel cylinder orifice, and the boring cutting edge is used to contact and process the orifice step plane and orifice bevel of the wedge-shaped wheel cylinder orifice.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The structural schematic diagram and bottom structural schematic diagram of this utility model are as follows: Figure 1 and Figure 3 As shown, this utility model includes a tool holder 1, a tool head 2, and a blade 3; one end of the tool head 2 is fixedly connected to the tool holder 1, and the other end of the tool head 2 is provided with multiple centrally symmetrically distributed blade mounting slots. Each blade mounting slot is provided with a blade 3 with multiple blade combinations. The blade 3 is used to process the wedge-shaped wheel cylinder bore 4 in one step.

[0025] The tool holder 1 has a side fixing end at its tail, and the combined tool is fixedly connected to the external side-fixed machining tool holder through the end face of the side fixing end.

[0026] More specifically, the blade mounting slot is set as a right-angle slot, and the right-angle slot has at least one edge for mounting the blade 3. The blade 3 is installed at the right angle or edge of the right-angle slot.

[0027] In practice, the blade 3 is set to be perpendicular to the axial plane of the parallel tool holder 1.

[0028] An enlarged schematic diagram of the blade of this utility model is shown below. Figure 4 As shown, the blade assembly of blade 3 consists of alternating chamfering blades and boring blades.

[0029] The blade 3 has chamfering and boring edges alternately arranged in the direction of the end.

[0030] The cutting edge shape of the blade 3 is the same as the shape of the bore wall of the wedge-shaped wheel cylinder bore 4 being machined. In practice, the outer contour of the blade 3 is designed according to the machining dimensions of the wheel cylinder bore.

[0031] A schematic diagram of the wedge-type wheel cylinder bore is shown below. Figure 2 As shown, the hole wall shape of the wedge-shaped wheel cylinder orifice 4 includes multiple orifice chamfers, orifice step planes, and orifice bevels; the chamfering cutting edge is used to contact and machine the orifice chamfers of the wedge-shaped wheel cylinder orifice 4, and the boring cutting edge is used to contact and machine the orifice step plane and orifice bevel of the wedge-shaped wheel cylinder orifice 4.

[0032] Four blade mounting slots are provided at intervals along the circumference of the cutter head 2, and a blade 3 is installed in each blade mounting slot.

[0033] The tool holder 1 and the tool head 2 are made of alloy structural steel, and the blade 3 is made of tungsten-cobalt material.

[0034] During production, the side-fixed molding machine with tool holder drives the combined tool to rotate continuously downwards. The boring edge of the blade 3 first contacts the wedge-shaped cylinder. As the side-fixed molding machine with tool holder rotates downwards, the stepped plane and the inclined surface of the wedge-shaped cylinder orifice 4 are machined. Then, the chamfering edge of the blade 3 is used to machine the chamfer of the wedge-shaped cylinder orifice 4. At the same time, the deeper stepped plane and the inclined surface of the wedge-shaped cylinder orifice 4 are machined by the boring edge of the blade 3. Then, the downward rotation continues, and the chamfering edge of the blade 3 is used for chamfering. When all parts of the wedge-shaped cylinder orifice 4 are machined, the side-fixed molding machine with tool holder stops rotating downwards and moves upwards, and the wedge-shaped cylinder orifice 4 is finished.
