[0041] The present invention will be further described below with reference to the accompanying drawings.

[0042] like Figures 1-5 As shown, a five-axis machining equipment for a pointed tail toothed plate includes an X-axis drive mechanism 1, a Y-axis drive mechanism 2, a tool setter 3, a cutting tool 4, a tool magazine 5, a Z-axis drive mechanism 6, a tool changer 7, a flipping mechanism 8, a rotating mechanism 9, a fixture body 10, and a toothed plate 11.

[0043] The five-axis machining equipment for pointed tail dies includes a Z-axis drive mechanism 6, an XY-axis drive mechanism, and a two-axis rotary fixture.

[0044] The XY axis drive mechanism includes an X-axis drive mechanism 1 and a Y-axis drive mechanism 2. The Y-axis drive mechanism 2 is mounted on the X-axis drive mechanism 1, and the two-axis rotary fixture is mounted on the Y-axis drive mechanism 2.

The rotating mechanism 9 is mounted on the flipping mechanism 8, and the fixture body 10 is mounted on the rotating mechanism 9. The fixture body 10 is used to hold the jaw plate.

The cutting arm is vertically oriented, and the cutting head is mounted on the cutting arm. In this embodiment, there are two types of machining tools: one is an end mill, which is located at the end of the cutting arm and is used for milling at sharp tail back elevation angles. The end mill can directly mill through the bottom surface of the tool, eliminating the need for milling by relying on the cutting arm in the traditional method, thus improving the tool's service life (in addition, traditional tools rely on the cutting arm for milling, resulting in obvious machining marks on the product surface); the other is a cutting tool, whose blade is set perpendicular to the cutting arm (the central axis of the cutting arm).

[0048] When the end mill is used for machining, the end mill is located above the tooth plate, and when the cutting tool is used for machining, the cutting tool is located in front of the tooth plate.

The tool changing mechanism has an inverted T-shaped structure and is driven by a rotary lifting cylinder. The tool changing mechanism enables tool changing between the tool magazine and the Z-axis drive mechanism.

[0050] The XY axis drive mechanism is also equipped with a tool setter at one end, which can prevent the machining accuracy of the product from being affected during the tool changing process.

[0051] Optical scales are installed on the X-axis drive mechanism, Y-axis drive mechanism, and Z-axis drive mechanism, which can improve the movement accuracy of the X, Y, and Z axes.

[0066] 6.4) The tool changing mechanism rotates 90° and then resets, completing the tool changing process;
