[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A double gear alignment tool comprises a clamping portion 1 and a double gear member 2. The clamping portion 1 is fixedly connected to a through-shaft 11 via a support plate 6. The through-shaft 11 has an open end integrated with a positioning assembly for positioning the double gear member 2. The top of the support plate 6 is integrated with a support plate 7 and a lifting assembly for adjusting the vertical position of the support plate 7. A positioning pin 8 is fixedly connected to the outer wall of the support plate 7. A through-hole 5 matching the positioning pin 8 is formed through the double gear member 2.

[0025] After the gears are aligned, the cam 11 is rotated to move the gears 12 so that the gears 13 are aligned with the cam 12 and the gears 14 are aligned with the cam 12. When the gears are aligned, the cam 11 is rotated to move the gears 12 so that the gears 13 are aligned with the cam 12 and the gears 14 are aligned.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the positioning assembly includes a positioning plate 3 and a limiting portion for limiting the axial position of the positioning plate 3. The positioning plate 3 is screwed together with the inner surface wall of the open end of the through-shaft 11 through the locking rod 4, and the outer surface wall of the positioning plate 3 abuts against the outer surface wall of the double-linked gear member 2. The limiting portion includes a rectangular block 13 fixedly connected to the positioning plate 3. The outer surface wall of the rectangular block 13 is inserted into the open end of the through-shaft 11 through the card groove 14, and the positioning plate 3, the rectangular block 13 and the inner surface wall of the through-shaft 11 are all screwed together with the outer surface wall of the locking rod 4. Next, insert the rectangular block 13 into the slot 14, the positioning plate 3 will abut the outer wall of the double gear part 2, and then screw the locking rod 4 to the positioning plate 3, the rectangular block 13 and the inner wall of the through shaft 11, so as to fix the positioning plate 3, thereby fixing the double gear part 2 and the support plate 6, ensuring the convenience of disassembly and assembly of the double gear part 2 and the support plate 6. At the same time, the cooperation between the rectangular block 13 and the slot 14 can prevent the locking rod 4 from loosening due to being coaxial with the through shaft 11.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the support plate 6 is fixedly connected to a boss 10 on the side away from the clamping part 1, and the outer wall of the boss 10 abuts against the outer wall of the double gear part 2, so as to avoid the double gear part 2 and the support plate 6 from being completely fitted. The lifting assembly includes a slide plate 9 and a fixing part for fixing the slide plate 9 and the support plate 6. The slide plate 9 is fixedly connected to the support plate 7. The outer wall of the slide plate 9 is slidably connected to the inner wall of the support plate 6. The fixing part includes a positioning rod 12 that is screwed together with the inner wall of the support plate 6. The open end of the positioning rod 12 abuts against the outer wall of the slide plate 9. When the support plate 7 is pulled vertically and the support plate 7 is linked to the positioning pin 8, the slide plate 9 slides along the inner wall of the support plate 6 until the distance between the positioning pin 8 and the through shaft 11 reaches the specified length. The positioning rod 12 is rotated so that its open end abuts against the outer wall of the slide plate 9, thereby achieving the fixation of the positioning pin 8 and the support plate 6.

[0028] Working principle: First, insert the first tooth of the small gear of the duplex gear part 2 based on the perforation 5. After the small gear is cut, install the clamping part 1 on the gear hobbing machine, and combine the center hole perforation 5 of the duplex gear blank after the small gear is processed with the through-shaft 11 and the positioning pin 8 respectively. After the positioning of the duplex gear part 2 is completed through the positioning plate 3, the large gear hobbing process is started to assist in completing the tooth alignment process of the duplex gear. Pull the support plate 7 vertically. While the support plate 7 is linked to the positioning pin 8, the slide plate 9 slides along the inner surface wall of the support plate 6 until the distance between the positioning pin 8 and the through-shaft 11 reaches the specified length. Then, rotate the positioning rod 12 so that its open end abuts against the outer wall of the slide plate 9 to realize the positioning pin 8. The fixing of the positioning pin 8 to the support plate 6 allows the position of the positioning pin 8 to be easily adjusted according to the size of the double gear part 2 while completing the auxiliary gear alignment processing of the double gear, thereby improving the double gear gear alignment tooling. The rectangular block 13 is inserted into the slot 14, and the positioning plate 3 will abut the outer wall of the double gear part 2. Then the locking rod 4 is screwed to the positioning plate 3, the rectangular block 13 and the inner wall of the through shaft 11 to achieve the fixing of the positioning plate 3, thereby achieving the fixing of the double gear part 2 and the support plate 6, ensuring the convenience of disassembly and assembly of the double gear part 2 and the support plate 6. At the same time, the cooperation of the rectangular block 13 and the slot 14 can prevent the locking rod 4 from being easily loosened due to being coaxial with the through shaft 11.
