[0034] like Figure 1 and Figure 3 As shown, the upper end face of the upper support 6 is fixedly connected to the longitudinal moving arm rail seat 11, and the longitudinal moving arm rail seat 11 and the longitudinal moving arm 12 are horizontally fitted together.

[0035] like Figure 1 and Figure 3 As shown, the rear end of the longitudinal moving arm 12 is equipped with the front end of the transversely swingable horizontal arm 13, the rear end of the transversely swingable arm 13 is equipped with the front end of the vertically swingable tool angle adjusting arm 14, and the rear end of the tool angle adjusting arm 14 is equipped with a detachable scraper 15.

[0036] As a preferred embodiment of this invention, such as Figure 1 As shown, the aperture 7 is engaged with the unthreaded portion of the vertical feed screw 8 near the upper end via a bearing.

[0037] As a preferred embodiment of this invention, such as Figure 2 As shown, a scale pointer 16 is fixedly installed on the base 1; scale lines 17 are engraved on the side of the vertical moving arm 5, and the scale pointer 16 points to the scale lines 17.

[0038] As a preferred embodiment of this invention, such as Figure 1 and Figure 3 As shown, the light hole 7 with bearing and the longitudinal moving arm rail seat 11 are independently set on the upper support seat 6.

[0039] As a preferred embodiment, the upper support 6 is fixedly connected to the vertical moving arm 5 by bolts.

[0040] As a preferred embodiment, the base 1 is fixedly mounted on the machine tool by bolts.

[0041] As a preferred embodiment of this invention, such as Figure 1 and Figure 3 As shown, a guide rail locker 18 is provided at the lower end of the guide rail seat 2, and the lower end of the guide rail 4 can be locked by the guide rail locker 18.

[0042] As a preferred embodiment of this invention, such as Figure 1 and Figure 3 As shown, a longitudinal moving arm locking device 19 is provided at the rear end of the longitudinal moving arm rail seat 11, and the front end of the longitudinal moving arm 12 can be locked by the longitudinal moving arm locking device 19.

[0043] As a preferred embodiment of this invention, such as Figure 1 and Figure 3 As shown, a transverse swing arm lock 20 is provided at the rear end of the longitudinal moving arm 12, and the front end of the transverse swing arm 13 can be locked by the transverse swing arm lock 20.

[0044] As a preferred embodiment of this invention, such as Figure 1 and Figure 3 As shown, a tool angle adjusting arm locker 21 is provided at the rear end of the transverse swing arm 13, and the front end of the tool angle adjusting arm 14 can be locked by the tool angle adjusting arm locker 21.

[0045] In this embodiment, the guide rail lock 18, the longitudinal moving arm lock 19, the transverse swing arm lock 20, and the tool angle adjusting arm lock 21 all employ commonly known locks in the art. The assembly and locking relationships between the locks and their corresponding arms adopt conventional assembly and locking relationships in the art.

[0046] In this preferred embodiment, multiple guide rail holes 22 are vertically opened on the guide rail 4, and screws are installed in the guide rail holes 22 to fix the guide rail 4 and the vertical moving arm 5 together.

[0047] In this embodiment, preferably, the vertical feed screw 8 is a screw that can be used for a ball screw pair, and the corresponding threaded feed support seat 10 is a feed support seat with balls. The two cooperate with each other to form a ball screw pair.

[0048] In this preferred embodiment, a lead screw groove 23 is vertically provided on the rear side wall of the base 1. The threaded portion of the vertical feed lead screw 8 passes through the threaded feed support 10 and enters the lead screw groove 23. The lead screw groove 23 can prevent spatial interference between the vertical feed lead screw 10 and the base 1.

[0049] The usage process of the multi-functional gear hobbing machine deburring device in this embodiment is as follows:

[0050] The base 1 is connected to the machine tool by bolts. By rotating the lead screw handwheel 9, the guide rail 4 moves up and down in the vertical lead screw groove 23 inside the base 1, which drives the upper support 6 and the vertical moving arm 5 to move up and down to adjust the height of the scraper 15 until the scraper 15 is in contact with the end face of the gear. Then, rotate the guide rail locking device 18 to lock the vertical moving arm 5. At this time, the scale pointer 16 will display the reading on the scale line 17 on the side of the vertical moving arm 5. Record this reading, and the next adjustment can be made directly according to the reading, which improves the adjustment efficiency.

[0051] The longitudinal moving arm 12 and the transverse swing arm 13 work together to adjust the distance between the scraper 15 and the center of the gear. After the base 1 is installed, the longitudinal moving arm 12 moves back and forth on the longitudinal moving arm rail seat 11. When the extension line of the longitudinal moving arm 12 passes exactly through the center of the gear, the longitudinal moving arm locking device 19 is rotated to lock the longitudinal moving arm 12. When the adjustment of the longitudinal moving arm 12 alone cannot meet the deburring requirements of the scraper 15, the transverse swing arm 13 is rotated so that the extension line of the transverse swing arm 13 passes through the center of the gear. After the scraper 15 is adjusted to the appropriate position in conjunction with the longitudinal moving arm 12, the longitudinal moving arm locking device 19 and the transverse swing arm locking device 20 are rotated to lock the longitudinal moving arm 12 and the transverse swing arm 13 respectively. The combined use of the longitudinal moving arm 12 and the transverse swing arm 13 is applicable to various machine tools, improving the applicability of the deburring device for multi-functional gear hobbing machines.

[0052] For some gear end faces with angles, adjust the tool angle adjusting arm 14 to make the scraper 15 fit perfectly with the gear end face, and then rotate the tool angle adjusting arm locking device 21 to lock the tool angle adjusting arm 14 for efficient deburring. This also improves the applicability of the deburring device for the multi-functional gear hobbing machine.

[0053] The scraper 15 is a detachable scraper, which can be replaced after it wears out.
