[0023] refer to Figure 1-4 As shown, one embodiment of this utility model is as follows:

[0024] A gear assembly device includes an assembly base 1, a positioning block 2 at the center of the assembly base 1, support arms 3 on both sides of the positioning block 2, a positioning groove 4 between the positioning block 2 and the support arms 3, a support positioning plate 5 slidably installed in the positioning groove 4, a support roller 6 at the upper end of the support positioning plate 5, a pick-and-place port 7 adapted to the support positioning plate 5 in the positioning groove 4, a gear positioning pin 8 threadedly connected to the support positioning plate 5, a guide sliding hole in one of the support arms 3, a guide sliding rod 9 on the guide sliding hole, a large gear positioning plate 10 at the end of the guide sliding rod 9, a gear positioning pin 8 threadedly connected to the large gear positioning plate 10, an adjusting screw 11 threadedly connected to the support arm 3, a pressing plate 12 at the front end of the adjusting screw 11, the pressing plate 12 being adapted to the large gear positioning plate 10 and the support positioning plate 5.

[0025] Specifically, such as Figure 1As shown, the support arm 3 includes two arms, one higher and one lower. Two adjusting screws 11 are threaded onto the higher support arm 3, and each adjusting screw 11 has an adjusting handwheel 13 at its rear end. The ends of the adjusting screws 11 are rotatably connected to the pressure plate 12.

[0026] In use, select a support positioning plate 5 of appropriate height according to the required assembly spacing, and place its lower end into the positioning groove 4 through the pick-and-place port 7. The distance by which the support positioning plate 5 protrudes from the small gear is the required assembly spacing. Then, place the small gear on the positioning block 2, and by rotating the adjusting screw 11, the support positioning plate 5 is pushed on the positioning groove 4 towards the small gear by the pressing plate 12 until the gear positioning pin 8 is engaged between the teeth of the small gear, thus positioning the small gear. Then, rotate the hot large gear into the boss of the small gear until the large gear contacts the support roller 6 on the support positioning plate 5. Further rotate the large gear to adjust it to the marked assembly position, and then quickly adjust the adjusting screw 11 on the support arm 3 to move the large gear positioning plate 10 towards the large gear until the gear positioning pin 8 is engaged between the teeth of the large gear, thus positioning the large gear. After cooling, remove it.

[0027] In practice, only one gear positioning pin 8 needs to be installed on one support positioning plate 5. When the gear positioning pin 8 is engaged between the teeth of the pinion, there should be a gap between the support positioning plate 5 and the end wall of the positioning groove 4 to ensure tight positioning of the pinion. Conversely, the other support positioning plate 5 can be pre-aggregated against the end wall of the positioning groove 4 to ensure stable positioning. With support positioning plates 5 installed on both sides, stable support for the large gear can be ensured, thus ensuring installation accuracy.

[0028] To improve practicality, both the large gear positioning plate 10 and the support positioning plate 5 include a vertical part 14. The lower end of the vertical part 14 is provided with a horizontal part 15. A limiting groove 16 is provided on the side of the vertical part 14 away from the pressure plate 12. The size of the limiting groove 16 is adapted to the gear positioning pin 8. Multiple through screw holes 17 are provided at the bottom of the limiting groove 16. Locking screws are connected to the through screw holes 17. A fixing screw hole 801 adapted to the locking screw is provided at the rear end of the gear positioning pin 8.

[0029] A support roller 6 is provided at the upper end of the vertical part 14 of the support positioning plate 5.

[0030] The rear of the gear positioning pin 8 adopts a rectangular structure to cooperate with the limiting slide groove 16 and prevent the gear positioning pin 8 from rotating. The multiple through screw holes 17 can be provided to adjust the position of the gear positioning pin 8 on the limiting slide groove 16 according to the installation requirements, that is, to adjust the position of the gear positioning pin 8 in the vertical direction, which improves its practicality.

[0031] To improve the stability of the large gear positioning plate 10 during movement, multiple guide slide rods 9 are evenly connected on the horizontal part 15 of the large gear positioning plate 10, and the number of guide slide holes is the same as the number of guide slide rods 9.

[0032] The upper sidewall of the positioning slide 4 is provided with a limiting plate 18 that adapts to the horizontal part 15. The limiting plate 18 ensures the stability of the horizontal part 15 on the supporting positioning plate 5 as it moves in the positioning slide 4.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
