Description

Technical Field

[0001] This utility model belongs to the field of gear turning cutters, and specifically relates to a herringbone gear turning cutter. Background Technology

[0002] Gear turning cutters are mainly used for rotary machining. They achieve the machining of parts by rotating the tool and the workpiece simultaneously. During the operation of the gear turning cutter, heat is generated. Overheating may reduce wear resistance, and impurities such as metal chips may be generated during the machining process, affecting the machining accuracy. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a herringbone tooth turning cutter.

[0004] The purpose of this utility model can be achieved through the following technical solution: a herringbone tooth turning cutter, including a tool holder, two sets of cutter heads respectively arranged symmetrically at the upper and lower ends of the tool holder, and a number of blades located on the side of the cutter heads, characterized in that a rotatable disk is provided on the cutter head, and a bearing for connection is provided between the cutter head and the disk.

[0005] The cutter head is provided with an annular groove, and the disc is provided with an air intake pipe that penetrates the disc and extends into the groove. On both sides of the air intake pipe located in the groove, there are two limiting rings with arc-shaped ends. The cutter head is provided with a second limiting ring, and a groove is provided between the second limiting ring and the cutter head for the first limiting ring to rotate inside.

[0006] The cutter head has an annular air guide groove that matches the air inlet pipe. Several air guide pipes are provided below the air guide groove, and several air outlet pipes extending to the cutter head are provided on the air guide pipes.

[0007] In the aforementioned herringbone tooth turning cutter, both the first limiting ring and the second limiting ring are provided with sealing parts.

[0008] In the aforementioned herringbone tooth turning cutter, both the upper and lower ends of the air intake pipe are provided with frustum-shaped mounting parts.

[0009] In the aforementioned herringbone tooth cutting tool, the blades located at the upper end of the cutting head and the blades located at the lower end of the cutting head are arranged in a symmetrical herringbone pattern.

[0010] In the aforementioned herringbone tooth turning cutter, there is a gap between the blades, and the air outlet pipe is connected to the gap between the blades.

[0011] Compared with existing technologies, the self-shaped tooth turning cutter achieves heat dissipation through air circulation inside the cutter head and tool holder, reducing the decrease in wear resistance caused by overheating. After the air is blown out, impurities are also blown away, avoiding the impact of impurities on machining accuracy. Attached Figure Description

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1 , Figure 2 , Figure 3 As shown, the herringbone tooth turning cutter includes a tool holder 1, two sets of cutter heads 2 which are symmetrically arranged at the upper and lower ends of the tool holder 1, and several blades 3 located on the side of the cutter heads 2. A rotatable disc 4 is provided on the cutter head 2, and a bearing 5 for connection is provided between the cutter head 2 and the disc 4.

[0018] The cutter head 2 has an annular groove 6, and the disc 4 has an air intake pipe 7 that passes through the disc 4 and extends into the groove. On both sides of the air intake pipe 7 located in the groove, there are limiting rings 8 with arc-shaped ends. The cutter head 2 has a limiting ring 9. A groove 10 is provided between the limiting ring 9 and the cutter head 2 to allow the limiting ring 8 to rotate inside.

[0019] The cutter head 2 has an annular air guide groove 11 that matches the air inlet pipe 7. Several air guide pipes 12 are provided below the air guide groove 11. Several air outlet pipes 13 extending to the cutter head 3 are provided on the air guide pipes 12. Both the first limiting ring 8 and the second limiting ring 9 are provided with sealing parts 14.

[0020] Before use, an air pump is connected through the air inlet pipe 7. Since the disc 4 can rotate and there is a bearing 5 between it and the cutter head 2, the air pump pipe is prevented from getting tangled during the rotation of the toothed cutting cutter.

[0021] After air is introduced into the intake pipe 7, the air will enter several air guide pipes 12 through the air guide groove 11 and then be discharged through the exhaust pipe 13.

[0022] During the inflation process of the intake pipe 7, the air in the air guide groove 11 forms a saturated state of circulation. At this time, the air phase expands at both ends, thereby resisting the limiting ring 8 and generating an upward thrust, which causes the sealing part 14 between the limiting ring 1 and the limiting ring 2 9 to be squeezed, thereby strengthening the sealing performance.

[0023] To elaborate further, both the upper and lower ends of the air intake pipe 7 are equipped with frustum-shaped mounting parts 15 for easy connection with the air pump.

[0024] To elaborate further, the blade 3 located at the upper end of the cutting head 2 and the blade 3 located at the lower end of the cutting head 2 are arranged in a symmetrical herringbone pattern.

[0025] To elaborate further, there is a gap between the blades 3, and the air outlet pipe 13 is connected to the gap between the blades 3 to facilitate the discharge of internal gas. At the same time, the airflow blows away the impurities generated during the processing.

[0026] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0027] Although this document frequently uses terms such as tool holder 1, tool head 2, blade 3, disc 4, bearing 5, annular groove 6, air inlet pipe 7, limiting ring one 8, limiting ring two 9, channel 10, air guide groove 11, air guide pipe 12, air outlet pipe 13, sealing part 14, and mounting part 15, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
