[0019] As Figure 1As shown, a quick-clamping main backlash measuring device includes: a measuring rod 1, with two symmetrical semi-circular ring clamping arms 2 at its first end. The ends of the semi-circular ring clamping arms 2 away from the measuring rod 1 are provided with connecting portions 3, with a gap between the two connecting portions 3 to keep the two semi-circular ring clamping arms 2 in an open state. The semi-circular ring clamping arms 2 will remain in a relatively open state without external force, so as to be fitted onto the main shaft.

[0020] A through hole is provided on the connecting part 3, and a connecting rod 4 is provided in the through hole. The first end of the connecting rod 4 extends to the side of the first connecting part 3 away from the second connecting part 3, and the second end extends to the side of the second connecting part 3 away from the first connecting part 3.

[0021] A stop block 5 is fixedly connected to the first end of the connecting rod 4, and a pin 6 perpendicular to the connecting rod 4 is provided at the second end, with the middle part of the pin 6 connected to the second end of the connecting rod 4.

[0022] The stop block 5 can fit against the side of the first connecting part 3. Preferably, the first end of the connecting rod 4 is provided with an external thread, and the center of the stop block 5 is provided with a threaded hole for threaded connection to the first end of the connecting rod 4. The threaded connecting rod 4 and the stop block 5 can be adjusted to meet the required relative positions to adapt to different usage conditions. To facilitate rotation of the stop block 5, the stop block 5 has a regular hexagonal columnar structure.

[0023] The pin 6 has a circular connecting plate 7 at both ends that are rotatably connected to it, and the pin 6 is connected to the circular connecting plate 7 at an eccentric position. The circular connecting plate 7 is equipped with a toggle handle 8 so that the operator can rotate the circular connecting plate 7.

[0024] A gasket 10 is provided between the circular connecting disc 7 and the connecting part 3, and the gasket 10 is sleeved on the connecting rod 4. The gasket 10 can cooperate with the stop block 5 to clamp the two connecting parts 3, so that the device is fixedly connected to the main shaft. At the same time, a rubber sheet is provided between the gasket 10 and the circular connecting disc 7 to increase friction and prevent slippage.

[0025] The measuring rod 1 has a connecting groove 9 in the middle for connecting a dial indicator.

[0026] Work process: such as Figure 2 As shown, the ring formed by the two semi-circular clamping arms 2 is placed on the main shaft of the drive axle main reducer. Then, the circular connecting plate 7 is rotated by using the lever 8. Since the pin 6 is located at the eccentric position of the circular connecting plate 7, it will drive the connecting rod 4 and the shim 10 to move relative to each other, making the distance between the shim 10 and the stop block 5 closer. This will drive the two connecting parts 3 to move closer to each other, thereby clamping the semi-circular clamping arms 2 and fixing the entire device on the main shaft. Then, the dial indicator is connected to the connecting groove 9, and the measuring rod 1 is rotated left and right to read the value on the dial indicator and measure the main shaft clearance.
