Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

As shown in fig. 1-2, the hand-held planetary gear assembly tool with the telescopic mechanism comprises a cylinder 3, wherein a vertical elastic connecting rod transmission mechanism is arranged in the cylinder 3, and a pressing block 7 is fixedly connected to the lower end of the elastic connecting rod transmission mechanism. The elastic connecting rod transmission mechanism comprises a handle 2 which is arranged on the outer side of the upper end of the cylinder, and the handle 2 is connected with a first connecting rod 11 through a first rotating shaft. The first link 11 extends through the cylinder. An intermediate shaft 15 is installed in the cylinder, a second connecting rod 13 is connected to the upper end shaft of the intermediate shaft 15, and the first connecting rod 11 and the second connecting rod 13 are connected through a second rotating shaft 12. The upper portion of jackshaft is provided with spring holder 14, installs the spring between the lower extreme of spring holder 14 and drum, and the spring cup joints on jackshaft 15. The lower extreme of drum is provided with guide block 4, installs the direction through-hole on the guide block 4. The intermediate shaft 15 penetrates through the guide through hole and the lower end of the intermediate shaft is fixedly connected with the guide rod.

The lower extreme of drum is connected with connecting block 5, and the lower extreme fixedly connected with guide bar 8 of connecting block 5, the lower extreme of guide bar 8 is connected with locating pin 9.

An end cap 1 is arranged at the upper end of the cylinder. A groove is formed in the outer side surface of the pressing block 7, and a pressing plate is embedded in the groove; the pressing plate is correspondingly arranged below the connecting block.

During assembly, the handle is firstly held, the middle shaft is driven to move downwards in the cylinder through the first connecting rod and the second connecting rod, so that the spring fixed on the middle shaft is driven to move downwards together, and a sufficient space is reserved between the pressing plate of the pressing block and the connecting block for placing the planetary gear 6. When the planetary gear 6 is placed in the handle, the handle is released, the intermediate shaft is driven to rise under the action of the resilience force of the spring, the second connecting rod, the first connecting rod and the handle are driven to rise, and the pressing block and the connecting block clamp the planetary gear. Then, the tooling is communicated with the planetary gear 6 and sent into the planet carrier, and the pressing plate always supports the middle process shaft under the action of the spring force in the process to prevent the process shaft from falling off until the process shaft is sent to a preset position, so that the tooling is loosened.
