[0022] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a high-precision positioning device for a motor stator, including a bottom plate 1 and a top plate 2. A plurality of support blocks 3 are fixed between the bottom plate 1 and the top plate 2. A plurality of connection grooves 4 are opened on the top surface of the top plate 2. An activity plate 5 is slidably connected to the inner side of the connection groove 4. A guide groove 6 is opened on the outer side of the activity plate 5. The guide groove 6 includes two vertical sections and an inclined section. A cylinder 7 is fixed on the top surface of the bottom plate 1. A connection plate 8 is fixed to the output end of the cylinder 7. The top surface of the connection plate 8 is fixedly connected to the lower end of the activity plate 5. A plurality of clamping assemblies 9 are further provided on the top surface of the top plate 2. Two supports 10 are provided on one side of the clamping assembly 9. The lower ends of the supports 10 are fixedly connected to the top surface of the top plate 2. Two guide rods 11 are slidably connected to the inner sides of the supports 10. A slider 12 is fixed to the outer side of the lower guide rod 11. The outer side of the slider 12 is slidably connected to the inner side of the guide groove 6;

[0023] The connecting plate 8 is pulled by the air cylinder 7, and the connecting plate 8 drives the movable plate 5 to move downward along the connecting groove 4 on the top plate 2. During this process, the slider 12 on the guide rod 11 slides upward along the guide groove 6 on the movable plate 5. When the slider 12 moves from the vertical section to the inclined section in the guide groove 6, the slider 12 is pushed, thereby driving the guide rod 11 to move towards the middle of the top plate 2. The guide rod 11 drives the clamping assembly 9 to move towards the middle of the top plate 2, thereby positioning the motor stator. When the slider 12 moves from the inclined section to the vertical section in the guide groove 6, the slider 12 is no longer pushed, so that the guide rod 11 and the clamping assembly 9 are kept in a fixed state. Since the distance of the slider 12 passing through the inclined section in the guide groove 6 is fixed, the moving distances of the guide rod 11 and the clamping assembly 9 are fixed, thus achieving high-precision repeated positioning and solving the problem that the repeated positioning accuracy of the air cylinder is poor, which affects the positioning accuracy.

[0024] Furthermore, the clamping assembly 9 includes a mounting seat 91 arranged above the top plate 2. One side of the mounting seat 91 is fixedly connected to one end of the guide rod 11. The other side of the mounting seat 91 is provided with an arc-shaped groove 92. A plurality of insertion slots 93 are arranged inside the arc-shaped groove 92. A clamping plate 94 is arranged inside the arc-shaped groove 92. The clamping plate 94 is of an arc-shaped structure. A plurality of insertion rods 95 are fixedly arranged on the circumferential outer side of the clamping plate 94. The lower ends of the insertion rods 95 are in plug-in fit with the inner sides of the insertion slots 93. The inner diameter of the arc-shaped groove 92 is the same as the outer diameter of the clamping plate 94. The connecting plate 8 is of a cross-shaped structure. A plurality of clamping assemblies 9 and a plurality of connecting grooves 4 are both arranged in a rectangular array;

[0025] When it is necessary to position motor stators with different outer diameters, by replacing the clamping plate 94 in the clamping assembly 9, the inner diameter of the clamping plate 94 is made to conform to the outer diameter of the motor stator, and the insertion rods 95 on the clamping plate 94 are aligned with the insertion slots 93 on the mounting seat 91 and inserted, the installation operation can be quickly completed, which is convenient and fast to use and improves the applicable range of the device.

[0026] The specific usage mode and function of this embodiment: In this utility model, the air cylinder 7 pulls the connecting plate 8, and the connecting plate 8 drives the movable plate 5 to move downward along the connecting groove 4 on the top plate 2. During this process, the slider 12 on the guide rod 11 slides upward along the guide groove 6 on the movable plate 5. When the slider 12 moves from the vertical section to the inclined section in the guide groove 6, the slider 12 is pushed, thereby driving the guide rod 11 to move towards the middle of the top plate 2. The guide rod 11 drives the clamping assembly 9 to move towards the middle of the top plate 2, thereby positioning the motor stator. When the slider 12 moves from the inclined section to the vertical section in the guide groove 6, the slider 12 is no longer pushed, so that the guide rod 11 and the clamping assembly 9 are kept in a fixed state. Since the distance of the slider 12 passing through the inclined section in the guide groove 6 is fixed, the moving distances of the guide rod 11 and the clamping assembly 9 are fixed, thus achieving high-precision repeated positioning;

[0027] When it is necessary to position the motor stator with different outer diameters, by replacing the clamping plate 94 in the clamping assembly 9, the inner diameter of the clamping plate 94 is made to conform to the outer diameter of the motor stator, and the insertion rod 95 on the clamping plate 94 is aligned with and inserted into the slot 93 on the mounting seat 91, and the installation operation can be quickly completed.
