[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided in conjunction with the appendix. Figures 1-4 The present invention will be further described in detail with reference to the embodiments. Example

[0036] An automatic cutting and assembly equipment for motor rotor gaskets, such as Figures 1 to 7 As shown, the system includes two sets of cutting and assembly sub-equipment, namely sub-equipment A and sub-equipment B. A space is provided between the two sets of sub-equipment for placing the motor rotor to be fitted with shims. The motor rotor to be fitted with shims is located in this space, and the two sets of sub-equipment can simultaneously fit shims onto both shafts of the motor rotor to improve assembly efficiency.

[0037] Each set of sub-equipment includes a strip conveying power mechanism, a strip conveying platform, a cutting component, a gasket fixing component, and a gasket mounting component. The strip conveying platform is a rectangular groove 3. The strip conveying power mechanism drives the strip to move in a stepping manner on the rectangular groove 3. The cutting component cuts gaskets sequentially from the strip. The cutting component is equipped with a gasket fixing component. The gaskets cut from the strip are fitted onto the gasket fixing component. The gasket fixing component is a cylinder 7. The cutting component includes a first cutting component, a second cutting component, and a lifting mechanism 4. The first cutting component and the second cutting component are arranged in parallel. Both the first cutting component and the second cutting component are driven to rise and fall by the lifting mechanism 4. The first cutting component and the second cutting component are located at the first station and the second station, respectively. The first cutting component cuts the inner circle on the strip located at the first station. The strip conveying power mechanism drives the part of the strip with the cut inner circle to move to the second station. The second cutting component cuts the outer circle concentric with the inner circle on the strip to form a gasket. By first cutting the inner circle and then cutting the outer circle to form the annular gasket, the cutting quality of the annular gasket can be improved. To improve processing efficiency, in this embodiment, the first cutting component and the second cutting component are driven by the lifting component to cut the inner circle at the first station and the outer circle at the second station simultaneously.

[0038] The portion of the cylinder 7 located inside the lifting mechanism 4 is fitted with a spring 8. The shim mounting component, consisting of the lifting mechanism 4, the second cutting component, the cylinder 7, and the spring 8, is responsible for transferring the shim on the cylinder 7 to the motor rotor 100.

[0039] This embodiment sets up a strip transmission power mechanism, a strip transmission platform, and a cutting component, so that the strip to be cut can be driven by the strip transmission power mechanism to move on the strip transmission platform. The cutting component cuts out annular gaskets on the strip in sequence. The cut annular gaskets are fitted onto the gasket fixing component. The gasket mounting component provides power to transfer the gaskets on the gasket fixing component to the motor rotor, thereby realizing automatic cutting and automatic assembly of the annular gaskets and improving the work efficiency of gasket installation.

[0040] In a preferred embodiment, the first cutting component is a small-inner-diameter cylindrical cutting needle 5, the second cutting component is a large-inner-diameter hollow cylindrical cutting needle 6, and the gasket fixing component is a cylinder 7 that passes through the interior of the large-inner-diameter hollow cylindrical cutting needle 6, with one end of the cylinder 7 protruding from the large-inner-diameter hollow cylindrical cutting needle 6. By using cylindrical cutting needles of different inner diameters, the required inner and outer circles can be quickly cut to form an annular gasket. The cut annular gasket fits perfectly onto the portion of the cylinder 7 that is protruding from the second cutting component.

[0041] In a preferred embodiment, the cylinder 7 is a movable cylinder 7 that can extend and retract along the length direction of the second cutting component, and the lifting mechanism 4 is provided with a groove for the cylinder 7 to be raised and lowered.

[0042] During the process of transferring the annular gasket from the cylinder 7 to the shaft of the motor rotor, the movable cylinder 7 can retract inward along the slide groove of the lifting mechanism 4 to facilitate separation from the annular gasket.

[0043] In a preferred embodiment, a limiting part 71 is provided at the other end of the cylinder 7. The limiting part 71 is located outside the second cutting member and inside the lifting mechanism 4. The limiting part 71 can prevent the cylinder 7 from detaching from the second cutting member.

[0044] In a preferred embodiment, a cutting guide is provided on the rectangular groove 3. The cutting guide has a first cutting channel 9 for the passage of small-diameter cylindrical cutting needles 5 and a second cutting channel 10 for the passage of large-diameter hollow cylindrical cutting needles 6. The first cutting channel 9 ensures that the small-diameter cylindrical cutting needles 5 travel along a specific path, and the second cutting channel 10 ensures that the large-diameter hollow cylindrical cutting needles 6 travel along a specific path, thereby smoothly cutting the inner and outer circles and improving the cutting accuracy.

[0045] In a preferred embodiment, the strip transmission power mechanism includes a motor, a driving wheel 1, and a driven wheel 2. The motor drives the driving wheel 1 to rotate, and the driven wheel 2 meshes with the driving wheel 1. The strip to be cut is conveyed to the rectangular groove 3 through the meshing of the driving wheel 1 and the driven wheel 2.

[0046] The working principle of the automatic cutting and assembly equipment for motor rotor pads in this embodiment is as follows:

[0047] The strip to be cut is conveyed into the rectangular groove 3 in a stepping manner through the meshing of the drive wheel 1 and the driven wheel 2. The lifting mechanism 4 drives the small inner diameter cylindrical cutting needle 5 and the large inner diameter hollow cylindrical cutting needle 6 to move synchronously towards the strip. At the same time, the inner circle and outer circle are cut out at the first station and the second station respectively, thereby realizing the cutting of the annular gasket at the second station. Since the large inner diameter hollow cylindrical cutting needle 6 has a cylinder 7 inside, and one end of the cylinder 7 is exposed outside the large inner diameter hollow cylindrical cutting needle 6, the cut annular gasket fits perfectly on the cylinder 7. At the exposed part of cylinder 7, the lifting mechanism 4 drives the large-diameter hollow cylindrical cutting needle 6 to move synchronously towards the motor rotor. The position of the motor rotor corresponds to that of the large-diameter hollow cylindrical cutting needle 6. When cylinder 7 touches the shaft of the motor rotor, as the large-diameter hollow cylindrical cutting needle 6 continues to move towards the motor rotor, cylinder 7 retracts into the large-diameter hollow cylindrical cutting needle 6. The large-diameter hollow cylindrical cutting needle 6 moves towards the motor rotor, placing the annular washer onto the shaft of the motor rotor. Figure 9 The diagram shows the structure of the motor rotor with a shim. Then, the lifting mechanism 4 drives the hollow cylindrical cutting needle 6 with a large inner diameter to reset. At this time, the cylinder 7 is also reset under the action of the spring 8, which can realize the cutting and assembly of the next annular shim. Example

[0048] The other structures in this embodiment are the same as in embodiment 1, except that: Figure 8 As shown, it also includes a turntable, which is located between the two sets of sub-equipment. The turntable has multiple stations, each station is used to fix a motor rotor, and the motor rotor is continuously fed by driving the rotation of the turntable.

[0049] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
