A second moving rod 23 is hingedly connected to the top of the first moving rod 22.

A limiting rod is fixedly connected to the inner wall of the insertion rod 21. The first moving rod 22 is slidably connected to the outer wall of the limiting rod. The outer wall of the first moving rod 22 is provided with a first hydraulic chamber 25. A first ratchet wheel 212 is fixedly sleeved on the outer wall of the first rotating rod 211. A first ratchet claw 213 is hingedly connected to the front of the movable plate 1. A spraying device 3 for spraying lubricating oil is arranged on the top of the movable plate 1. An expansion device 4 for assisting in clamping the motor base 8 is arranged on the top of the movable plate 1. The base 5 serves as a foundation. The motor 6 and the movable plate 1 are supported and connected by the supporting columns 7 and the motor base 8 respectively. When the motor shell needs to be positioned, the insertion rod 21 on the top of the movable plate 1 is cooperatively driven by the first rotating rod 211, the first moving rod 22, the second moving rod 23 and the elastic extension rods 24 to realize flexible clamping of the motor shell. The first rotating rod 211 rotates in the sliding groove to drive the first moving rod 22 and the second moving rod 23 to adjust to the appropriate position and angle. The elastic extension rods 24 provide adaptive deformation to uniformly distribute the clamping force and prevent damage to the motor shell. At the same time, the sliding connection of the limiting rod and the first moving rod 22 ensures the stability and accuracy of the movement of the moving rod.

In addition, the second hydraulic assembly assembled on the top of the movable plate 1 provides power support for the spraying device 3, ensuring the timeliness and accuracy of the spraying action. The second hydraulic assembly comprises a third hydraulic chamber 39, a rack 38 slidably connected to one end of the piston inside the third hydraulic chamber 39, the rack 38 and the circular gear 37 are meshed with each other, a fourth hydraulic chamber 310 is assembled on the side of the first moving rod 22, a third hydraulic rod 311 is slidably connected to one end of the piston inside the fourth hydraulic chamber 310, a second spring 313 is movably sleeved on the outer wall of the third hydraulic rod 311, a second connecting hose 312 is fixedly connected to the back of the fourth hydraulic chamber 310, and the other end of the second connecting hose 312 is fixedly connected to the fourth hydraulic chamber 310.

This air bag 41 expansion type clamping method not only can adapt to motor bases 8 of different shapes and sizes, but also can effectively avoid the deformation or damage of the motor base 8 caused by the traditional rigid clamping, thereby improving the reliability and safety of clamping. At the same time, the flexible contact characteristics of the air bag 41 can absorb certain vibration and impact during the operation of the motor 6, thereby further improving the stability and service life of the motor 6 during operation. In addition, by accurately controlling the flow and pressure of the hydraulic oil in the fifth hydraulic bin 42, the expansion degree of the air bag 41 can be flexibly adjusted to realize precise adjustment of the clamping force, meet the assembly and processing requirements of different motor bases 8, and enhance the universality and practicality of the whole positioning tool.
