[0025] Example: A gearbox assembly fixture, such as Figure 1 - Figure 4 As shown, it includes a processing table 1, a fixed frame 2 fixedly installed on the top of the processing table 1, the fixed frame 2 is L-shaped, a lifting platform 3 is movably installed on one side of the fixed frame 2, an assembly rod 4 is installed at the bottom of the lifting platform 3, an assembly block 5 is installed at the bottom of the assembly rod 4, the assembly block 5 is semi-circular, and an installation platform 6 is movably installed below the assembly rod 4.
[0026] like Figure 1 - Figure 3As shown, an electric push rod 7 is fixedly installed on one side of the top of the fixed frame 2. The fixed frame 2 has a sliding groove 8, and a sliding rod 9 is fixedly installed inside the sliding groove 8. A lifting plate 10 is movably installed on the outside of the sliding rod 9. The sliding rod 9 passes through the lifting rod and is fixed. The lifting plate 10 slides up and down along the sliding rod 9. The top of the lifting plate 10 is fixedly connected to the telescopic end of the electric push rod 7. The sliding groove 8 and the sliding rod 9 of the fixed frame 2 cooperate to limit the lifting plate 10. One side of the lifting plate 10 is fixedly connected to the lifting platform 3. A spring 11 is movably installed on the outside of the sliding rod 9. The spring 11 is sleeved on the outside of the sliding rod 9. The lifting plate 10 supports the spring. 11 is compressed, and spring 11 lifts the lifting plate 10 by releasing its elastic force. Assembly rod 4 and assembly block 5 move up and down through the lifting plate 10 with the help of electric push rod 7. The electric push rod 7 on one side of the fixed frame 2 is activated by the control switch. The telescopic end of electric push rod 7 descends and presses down on the lifting plate 10. The lifting plate 10 slides down on the slide rod 9 inside the slide groove 8 of the fixed frame 2. The lifting plate 10 compresses the bottom spring 11. The lifting plate 10 drives the lifting platform 3 on one side to descend, which drives the assembly rod 4 and assembly block 5 at the bottom to press down on the gear 13, pressing the center hole of the gear 13 into the gear 13 housing spindle.
[0027] like Figure 1 - Figure 4 As shown, a motor 12 is fixedly installed inside the processing table 1. A gear 13 is movably installed on the top of the motor 12. A mounting platform 6 is movably installed on one side of the gear 13. A secondary wheel 14 is installed at the bottom of the mounting platform 6. The gear 13 and the secondary wheel 14 are meshed and connected. The secondary wheel 14 rotates through the gear 13 and the motor 12. The top of the secondary wheel 14 is fixedly connected to the mounting platform 6. The mounting platform 6 rotates through the meshing of the gear 13 and the secondary wheel 14. A locking groove 15 is opened at the top of the mounting platform 6. Positioning rods 16 are fixedly installed on both sides of the locking groove 15. The motor 12 inside the processing table 1 is started by the control switch. The motor 12 drives the top gear 13 to rotate. The gear 13 meshes with the auxiliary wheel 14 and rotates. The auxiliary wheel 14 drives the top mounting platform 6 to rotate. At this time, the assembly block 5 presses one side of the gear 13. The spring 11 inside the slide groove 8 of the fixing frame 2 releases its elasticity and lifts the lifting plate 10 upward, so that the assembly block 5 leaves the gear 13 box. The turntable rotates and the gear 13 rotates. The electric push rod 7 is started to press down, which drives the assembly rod 4 and the assembly block 5 to continuously press down on the edge of the gear 13.
[0028] Working principle: First, move the device to the assembly area of gear box 13. Place gear box 13 above mounting platform 6. Engage the gear box mandrel with the mounting platform 6 engagement groove 15. Engage the bolt holes on gear box 13 with the positioning rods 16 on both sides of the groove. Align the gear 13 to be installed with the mandrel inside gear box 13. Then, activate the electric push rod 7 on one side of the fixing frame 2 via the control switch. The telescopic end of the electric push rod 7 descends and presses down the lifting plate 10. The lifting plate 10 slides down on the sliding rod 9 inside the sliding groove 8 of the fixing frame 2. The lifting plate 10 compresses the bottom spring 11. The lifting plate 10 drives the lifting platform 3 on one side to descend, which in turn drives the assembly rod 4 and assembly block 5 at the bottom to press down the gear 13, pressing the center hole of gear 13 into the gear box mandrel.
[0029] During the pressing process of assembly block 5, the motor 12 inside the processing table 1 is started by the control switch. The motor 12 drives the top gear 13 to rotate. The gear 13 meshes with the auxiliary wheel 14 and rotates. The auxiliary wheel 14 drives the top mounting platform 6 to rotate. At this time, the assembly block 5 presses one side of the gear 13. The spring 11 inside the slide groove 8 of the fixing frame 2 releases its elastic force and lifts the lifting plate 10 upward, so that the assembly block 5 leaves the gear 13 box. The turntable rotates and the gear 13 rotates. The electric push rod 7 is started to press down, which drives the assembly rod 4 and the assembly block 5 to continuously press down on the edge of the gear 13, so that the gear 13 is stably installed inside the gear 13 box.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
