DETAILED DESCRIPTION

[0021] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0022] As Figures 1 to 6 shown, the utility model provides:

[0023] A clamping device for motor stator processing, including base 1, the top of base 1 is provided with support frame 3 for moving clamping assembly, clamping assembly includes moving plate 4, the bottom of moving plate 4 is provided with air cylinder 8, and the telescopic end of air cylinder 8 is provided with drive frame 5, the bottom of drive frame 5 is provided with connecting rod 10, and the bottom of connecting rod 10 is provided with positioning disc 9, and the lower annular array of positioning disc 9 has extrusion assembly for extruding the inner wall of stator.

[0024] By operating moving plate 4, clamping assembly and stator can be moved to the required working position. Workers can quickly and accurately position the stator to the specified work site according to actual needs. In addition, by using the driving function of drive frame 5, the extrusion assembly can be effectively driven to accurately clamp the stator. The addition of drive frame 5 not only improves the working efficiency of the clamping assembly, but also ensures the stability and reliability of the clamping process, thereby ensuring the smooth progress of the entire production process.

[0025] AsFigure 6 As shown in the drawings, the extrusion assembly comprises a pressing plate 15 and a connecting plate 16; the bottom of the pressing plate 15 is rotatably provided with a plurality of first connecting blocks 19; one end of the first connecting block 19 is rotatably provided with a top block 18 for extruding the inner wall of the stator; the bottom of the top block 18 is rotatably provided with a second connecting block 20; one end of the second connecting block 20 is rotatably connected to the top of the connecting plate 16.

[0026] By moving the positioning disc 9 downward to apply pressure to the first connecting block 19 and the second connecting block 20. This pressure will be transmitted to the top block 18, causing it to move outward. The outward movement of the top block 18 will generate an extrusion effect, directly acting on the inner ring part of the stator. As the extrusion effect increases, the friction between the stator inner ring and the top block 18 will also increase accordingly. This increased friction makes it easier to move the stator, thereby achieving more accurate positioning and adjustment.

[0027] As shown in the drawings, Figure 4 and Figure 5 the inside of the pressing plate 15 is threadedly connected with a screw rod 11; the top end of the screw rod 11 extends into the inside of the drive frame 5 and is rotatably connected with the inner wall of the drive frame 5; the bottom of the screw rod 11 is rotatably connected with the top of the connecting plate 16; the outside of the screw rod 11 is provided with a driven wheel 13.

[0028] The rotation of the driven wheel 13 will drive the screw rod 11 threadedly connected therewith to also start rotating. This allows the positioning disc 9 outside the screw rod 11 to move downward along the axis of the screw rod 11. Ensuring accurate position adjustment of the positioning disc 9.

[0029] As shown in the drawings, Figure 4 the inside of the rotating frame is provided with a motor 14; the output shaft of the motor 14 is provided with a driving wheel 12 meshingly connected with the driven wheel 13.

[0030] By starting the rotation of the output shaft of the motor 14, the driving wheel 12 can be effectively driven to start rotating. With the rotation of the driving wheel 12, it will further transmit power to cause the driven wheel 13 to also start rotating.

[0031] As shown in the drawings, Figure 5 and Figure 6 the bottom of the pressing plate 15 is provided with symmetrical limiting telescopic rods 17; the telescopic end of the limiting telescopic rod 17 is connected with the top of the pressing plate 15.

[0032] By using the limiting telescopic rod 17, the position deviation of the pressing plate 15 during movement can be effectively prevented. Ensuring that the pressing plate 15 can move vertically when moving.

[0033] As shown in the drawings, Figure 1 and Figure 2As shown, the inside of the support frame 3 is provided with an electromagnetic slide rail 6; the top of the moving plate 4 is provided with an electromagnetic slide block 7 that cooperates with the electromagnetic slide rail 6 to slide; and the top of the base 1 is provided with a placing groove 2 for placing the stator.

[0034] The electromagnetic slide block 7 moves on the surface of the electromagnetic slide rail 6 accurately, so that the clamping assembly can be flexibly positioned and moved to a suitable position. This provides great convenience for the next processing step. In addition, by using the design of the placing groove 2, the stator can be conveniently placed, so that the clamping assembly can easily and accurately clamp the stator, ensuring the efficiency and accuracy of the processing process.

[0035] Working principle: when multiple stators need to be clamped and moved at the same time, the multiple stators are placed in different placing grooves 2, at which time the electromagnetic slide block 7 is controlled to move on the surface of the electromagnetic slide rail 6, thereby driving the clamping assembly to move to a suitable position, and then the driving frame 5 and the positioning disc 9 are driven to move downward by the air cylinder 8, and at the same time, the position deviation of the lower pressing plate 15 during movement can be effectively prevented by using the limiting telescopic rod 17. It is ensured that the lower pressing plate 15 can move vertically during movement, until the extrusion assembly is moved to the inside of the inner circle of the stator. At this time, the motor 14 can be started to drive the driving wheel 12 to rotate, and then the driven wheel 13 is driven to rotate by the driving wheel 12, and further drives the screw rod 11 to rotate, and the rotation of the screw rod 11 can drive the positioning disc 9 outside to move downward, and when the positioning disc 9 moves downward, it will extrude the first connecting block 19 and the second connecting block 20, drive the top block 18 to move outward, and the outward movement of the top block 18 will extrude the inner circle of the stator, thereby increasing the friction with the inner circle of the stator. This can move the clamping assembly upward by the air cylinder 8 under the action of the electromagnetic slide block 7 to the designated processing site. When the clamping of the stator needs to be released, the motor 14 is only required to be reversely rotated, thereby driving the top block 18 to move inward and away from the contact with the inner circle of the stator.

[0036] The above embodiments only express one motor stator machining clamping device or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
