[0022] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0023] like Figure 1-4As shown, the utility model includes a positioning mechanism installed on a workbench 1 and used to place a gear 15 and a bushing 14, and a pressing mechanism that can be raised and lowered and adjusted to press the bushing 14 into the center hole of the gear 15 is arranged above the positioning mechanism. The positioning mechanism includes a base 11 that is detachably connected to the workbench 1, a mounting cylinder 2 is connected to the base 11, the bottom surface of the mounting cylinder 2 is open, and a guide through hole 16 is arranged on the top surface of the mounting cylinder 2. A spring 13 is arranged in the mounting cylinder 2, the bottom of the spring 13 is in contact with the base 11, and a support plate 17 is connected to the upper part of the spring 13. A guide column 3 is installed in the guide through hole 16, and the lower end of the guide column 3 is in contact with the support plate 17. The guide column 3 can be raised and lowered and adjusted as the spring 13 expands and contracts. When the spring 13 is naturally relaxed, the guide column 3 extends out of the guide through hole 16 under the support of the support plate 17.

[0024] In this embodiment, a bracket 7 is mounted on the workbench 1, a hydraulic cylinder 8 is mounted on the bracket 7, a pressing head is detachably connected to the piston rod 6 of the hydraulic cylinder 8, and the pressing head includes a connecting rod 9, and a stamping step 10 is provided on the bottom surface of the connecting rod 9. Furthermore, the connecting rod 9 is threadedly connected to the piston rod.

[0025] In this embodiment, a plug-in block 12 is provided on the bottom surface of the base 11, and a slot for inserting the plug-in block 12 is provided on the workbench 1. The workbench 1, the base 11 and the mounting tube 2 are connected through bolts.

[0026] In this embodiment, in order to facilitate the use of the gear 15 and the bushing 14, a material placing tray 5 is provided on both sides of the workbench 1, and the positioning mechanism is located between the two material placing trays 5, one of which is used to place the gear 15, and the other is used to place the bushing 14. Furthermore, each material placing tray 5 is tilted, and the height decreases toward the side close to the positioning mechanism.

[0027] In this embodiment, an annular positioning boss 4 is provided on the top surface of the mounting tube 2, and an annular groove matching the annular positioning boss 4 is provided on the gear 15. When the gear 15 contacts the mounting tube 2, the annular positioning boss 4 is embedded in the annular groove to position the gear 15.

[0028] When in use, first put the gear 15 on the guide column 3, and then put the bushing 14 on the guide column 3. At this time, the bushing 14 and the gear 15 are in a stacked state, start the hydraulic cylinder 8, and the stamping step 10 descends. The stamping step 10 presses the bushing 14 to make it descend and embed into the center hole of the gear 15. When the bushing 14 descends, the guide column 3 descends under the pressure of the stamping step 10. After the assembly is completed, the stamping step 10 rises, and under the action of the spring 13, the guide column 3 rises and resets.

[0029] The present application realizes the positioning of the bushing 14 and the gear 15 through a positioning mechanism, so as to avoid the bushing 14 being installed off-center when pressed down. The pressing mechanism and the positioning mechanism cooperate with each other to realize the press-fit assembly of the bushing 14 and the gear 15 by mechanical means, which can effectively improve the assembly efficiency and reduce the labor intensity.
