[0002] Gears are an important mechanical component. They are a type of mechanical component with teeth on the rim that continuously mesh to transmit motion and power. Through the meshing action of the teeth, they transmit the rotational motion of the driving wheel to the driven wheel, thereby achieving power transmission and speed conversion.

However, existing press-fitting equipment does not perform pressure monitoring and stroke monitoring during the press-fitting process. Since some existing gears are plastic gears or powder gears, these gears are usually fragile. Therefore, these press-fitting equipment without pressure monitoring or stroke monitoring are prone to scratches, cracks and deformation of the gears when press-fitting such gears.

In addition, the pressing device is small in size, effectively utilizes space, and can be used in a small space.

[0025] Combine Figures 1 to 4 As shown, the gear shaft pressing equipment of this embodiment includes a carrier 10, a pressing part 20 and a monitoring part 30. The carrier 10 can install the gear and the shaft so that the gear shaft can be pressed later. The pressing part 20 presses the gear shaft so that the shaft is installed in the gear to complete the pressing operation. The monitoring part 30 monitors the pressure on the gear during the pressing process and monitors the downward pressing stroke to effectively avoid scratches, cracks and deformation of the gear.

[0026] In this embodiment, the press-fitting device further includes a frame 40 , and the press-fitting part 20 is disposed on the frame 40 .

[0027] Combine Figure 1 and Figure 3 As shown, a material cavity 11 is provided on the carrier 10 of this embodiment to accommodate the gear shaft to be pressed. The material cavity 11 is located at the center of the carrier 10, and the material cavity 11 corresponds to the position of the pressing part 20, so that the pressing part 20 presses down the shaft, thereby rotating the shaft into the gear to complete the gear shaft pressing operation.

[0028] Combine Figure 1 、 Figure 2 as well as Figure 4As shown, the pressing part 20 of this embodiment includes a pressing driver 21 and a pressing piece 22. The pressing driver 21 drives the pressing piece 22 to press the gear shaft. The pressing piece 22 includes a pressing block 221 and a pressing pin 222. The pressing block 221 presses the gear, and the pressing pin 222 presses the shaft into the gear. There are two pressing blocks 221 and they are arranged opposite to each other. The monitoring part 30 includes a monitoring block 31, a pressure sensor 32 and a stroke detector 33. The monitoring block 31 is located between the pressing driver 21 and the pressing piece 22 and is driven by the pressing driver 21. The pressure sensor 32 is located on the monitoring block 31 to monitor the pressure on the carrier 10 during press-fitting. The stroke detector 33 is located on the side of the monitoring block 31 to monitor the monitoring block 31. 1's moving stroke, in actual use, the press-fitting driver 21 of this embodiment is a driving electric cylinder, and the press-fitting driver 21 drives the pressing piece 22 to move through the monitoring block 31, and the pressing block 221 of the pressing piece 22 presses the gear downward, and then the monitoring block 31 continues to move, and the pressing pin 222 presses the axis into the gear, thereby completing the gear axis press-fitting operation, and the pressure sensor 32 located on the monitoring block 31 can monitor the pressure of the monitoring block 31 in real time, that is, it realizes real-time monitoring of the force condition of the gear during the press-fitting process, and adjusts the driving force of the press-fitting driver 21 in real time according to the force condition of the gear to avoid scratches, cracks and deformation of the gear, thereby realizing protection of the gear during the press-fitting process.

[0029] In this embodiment, a protruding block 60 is provided on one side of the monitoring block 31, and the protruding block 60 presses down the stroke detector 33. The downward pressure of the stroke detector 33 is used to realize the real-time reflection of the movement stroke of the monitoring block 31. According to the real-time data of the stroke detector 33, the driving force of the press-fitting driver 21 is adjusted in real time to avoid scratches, cracks and deformation of the gears, thereby realizing the protection of the gears during the press-fitting process.

[0030] Specifically, in this embodiment, the stroke detector 33 is disposed on the frame 40 via a bracket.

The reinforcing cylinder 51 drives the reinforcing block 52, and the reinforcing block 52 squeezes the pressing block 221 to reduce the distance between the two pressing blocks 221 to improve the pressing accuracy of the pressing block 221 on the gear, thereby improving the pressing accuracy of the gear axis.

[0033] The gear shaft center pressing device of this embodiment is used in practice. The gear and the shaft center are placed in the material cavity 11. The pressing driver 21 of the pressing part 20 drives the pressing piece 22 to move through the monitoring block 31. The pressing block 221 of the pressing piece 22 presses the gear downward. Then the monitoring block 31 continues to move, and the pressing pin 222 presses the shaft center into the gear, thereby completing the gear shaft center pressing operation. The pressure sensor 32 located on the monitoring block 31 can monitor the pressure of the monitoring block 31 in real time, that is, it realizes real-time monitoring of the force condition of the gear during the pressing process. According to the force condition of the gear, the driving force of the pressing driver 21 is adjusted in real time to avoid scratches, cracks and deformation of the gear, thereby realizing protection of the gear during the pressing process. The stroke detector 33 realizes real-time reflection of the movement stroke of the monitoring block 31. According to the real-time data of the stroke detector 33, the driving force of the pressing driver 21 is adjusted in real time to avoid scratches, cracks and deformation of the gear, thereby realizing protection of the gear during the pressing process.
