Description

Technical Field

[0001] This utility model relates to the technical field of stator inspection mechanisms, specifically to a stator inspection mechanism. Background Technology

[0002] The stator is the stationary part of an electric motor or generator. During the production process, coils need to be wound onto the stator. To improve winding efficiency, current technologies use automated equipment for winding. After winding, the coils need to be inspected. In existing technologies, the wound stators on the conveyor line are manually removed, flipped, and inspected before being placed on appropriate fixtures for transport to the next process. This method increases the labor intensity of workers, reduces the efficiency of stator inspection, and the overall weight of the wound stator is relatively large, making it easy for workers to drop and injure them if handled improperly, thus reducing the safety of stator inspection. Therefore, a stator inspection mechanism that improves inspection efficiency and safety is proposed. Summary of the Invention

[0005] Preferably, the rotating frame is also equipped with a bearing for fixing the internal expansion chuck and a sensor for identifying stator reset.

[0006] Preferably, a zero-position identification block is also fixedly installed on the internal expansion clamp to facilitate sensor identification.

[0007] Preferably, the rotating frame is also equipped with a rotation limiting block and a first buffer block and a second buffer block that are used in conjunction with the rotation limiting block, are installed on the inspection bracket, and buffer the rotating frame.

[0008] Preferably, the lifting seat includes a lifting cylinder mounted on the inspection bracket and a lifting base connected to the lifting cylinder and fixing the rotating cylinder.

[0009] Preferably, the lifting base is also equipped with several guide rods and guide sleeves that are adapted to the guide rods and installed on the inspection bracket.

[0010] Preferably, the system also includes a lifting mechanism mounted on the inspection bracket; the lifting mechanism includes a lifting cylinder and a lifting plate connected to the lifting cylinder.

[0011] Preferably, the lifting plate is also equipped with several lifting guide rods and lifting guide sleeves that are adapted to the lifting guide rods and fixed on the inspection bracket.

[0012] The beneficial effects of this utility model are as follows: by using an internal expansion chuck to grip the stator, and the lifting seat driving the internal expansion chuck and the stator to rise and fall, the stator can be automatically extracted and placed, thereby improving the efficiency and safety of inspection and reducing the labor intensity of workers.

[0013] By using a rotary cylinder to drive the rotating frame to rotate, and the rotating frame to drive the stator to rotate, workers can directly inspect the winding condition inside the stator from the bottom of the stator, thereby improving the convenience of inspection.

If the specific posture changes, the directional indication will also change accordingly.

[0021] See appendix Figure 1-3 As shown, this embodiment of a stator inspection mechanism includes an inspection bracket 1; characterized in that a lifting seat 2 is movably mounted on the inspection bracket 1; a rotary cylinder 3 capable of rotating the stator and a rotary frame 4 connected to the rotary cylinder 3 are mounted on the lifting seat 2; an inner expansion chuck 5 for fixing the stator and a second rotary cylinder 6 for driving the inner expansion chuck 5 to rotate and reposition the stator are mounted on the rotary frame 4; by using the inner expansion chuck 5 to grip the stator, the lifting seat 2 drives the inner expansion chuck 5 and the stator to move up and down, realizing automated extraction and placement of the stator, thereby improving inspection efficiency and reducing the labor intensity of workers; by using the rotary cylinder 3 to rotate the stator, workers can directly inspect the winding condition inside the stator from the bottom, thereby improving the convenience of inspection; by using the second rotary cylinder 6 to rotate the inner expansion chuck 5, the inner expansion chuck 5 drives the stator to rotate, automatically repositioning the inspected stator instead of manually, so that the stator can be accurately placed into the tooling.

[0022] See appendix Figure 1-2 As shown, the rotating frame 4 is also equipped with a bearing 501 for fixing the inner expansion chuck 5 and a sensor 502 for identifying the stator reset; the inner expansion chuck 5 is also fixedly equipped with a zero-position identification block 503 for easy identification by the sensor 502; by using the sensor 502 to identify the zero-position identification block 503, it is easier to reset the stator and then place it on the tooling, thereby improving the accuracy of placement.

[0023] See appendix Figure 2 As shown, the rotating frame 4 is also equipped with a rotation limiting block 401 and a first buffer block 402 and a second buffer block 403 that are used in conjunction with the rotation limiting block 401 and installed on the inspection bracket 1 to buffer the rotating frame 4. When the rotating frame 4 drives the rotation limiting block 401 to rotate, the first buffer block 402 and the second buffer block 403 are used to buffer the rotation limiting block 401 respectively, thereby facilitating the buffering of the rotating frame 4.

[0024] See appendix Figure 2As shown, the lifting base 2 includes a lifting cylinder 201 mounted on the inspection bracket 1 and a lifting base 202 connected to the lifting cylinder 201 and fixing the rotary cylinder 3; the lifting base 202 is also equipped with a plurality of guide rods 203 and guide sleeves 204 adapted to the guide rods 203 and mounted on the inspection bracket 1; the lifting cylinder 201 drives the lifting base 202 to move up and down along the guide sleeves 204, and the lifting base 202 drives the rotary cylinder 3, the rotary frame 4 and the inner expansion chuck 5 to move up and down, thereby facilitating the extraction and placement of the stator.

[0025] See appendix Figure 1 , 3 As shown, it also includes a lifting mechanism 7 installed on the inspection bracket 1; the lifting mechanism 7 includes a lifting cylinder 701 and a lifting plate 702 connected to the lifting cylinder 701; the lifting plate 702 is also equipped with a plurality of lifting guide rods 703 and a lifting guide sleeve 704 adapted to and fixed on the inspection bracket 1; by pushing the lifting plate 702 along the lifting guide sleeve 704 through the lifting cylinder 701, the tooling for placing the stator is lifted upward, so that the tooling for placing the stator is removed from the conveying device, thereby facilitating the lifting of the tooling for placing the stator from the conveying device.

[0026] In the operation of this utility model, after the tooling containing the stator is transported to the stator inspection mechanism, the lifting cylinder 701 pushes the lifting plate 702 to move upward along the lifting guide sleeve 704, lifting the tooling containing the stator upward, so that the tooling containing the stator is separated from the conveying device. Then, the lifting cylinder 201 drives the lifting base 202 to descend along the guide sleeve 204. The lifting base 202 drives the rotating cylinder 3, the rotating frame 4, and the inner expansion chuck 5 to descend until the inner expansion chuck 5 extends into the interior of the stator and clamps the stator. Then, the lifting cylinder 201 drives the lifting base 202 to rise along the guide sleeve 204. The lifting base 202 drives the rotating cylinder 3, the rotating frame 4, the inner expansion chuck 5, and the stator held by the inner expansion chuck 5 to rise. Then, the rotating cylinder 3 drives the rotating frame 4 to rotate, and the rotating frame 4 drives the inner expansion chuck 5 and the stator held by the inner expansion chuck 5 to rotate 90 degrees until the rotation limit block 401 contacts the second buffer block 403. The second buffer block 403 buffers the rotating frame 4. At this time, the operator can move the stator. The winding condition is checked, and the stator can also be manually rotated to check various angles inside the stator. After the inspection is completed, the rotary cylinder 3 drives the rotary frame 4 to rotate in the opposite direction. The rotary frame 4 drives the inner expansion chuck 5 and the stator held by the inner expansion chuck 5 to rotate 90 degrees to reset, until the rotation limit block 401 contacts the first buffer block 402. The first buffer block 402 buffers the rotary frame 4. Then, the second rotary cylinder 6 drives the inner expansion chuck 5 to rotate, and the inner expansion chuck 5 drives the stator to rotate. At the same time, the sensor 5 is used. 02. The zero-position identification block 503 is identified, and the stator is reset to the zero position. Then, the lifting cylinder 201 drives the lifting base 202 to descend along the guide sleeve 204. The lifting base 202 drives the rotating cylinder 3, the rotating frame 4, the inner expansion chuck 5, and the stator held by the inner expansion chuck 5 to descend. The inspected stator is placed on the tooling. Finally, the lifting cylinder 701 pushes the lifting plate 702 to move downward along the top lifting guide sleeve 704 to place the tooling on which the stator is placed on the conveying device to continue to be conveyed to the next process.
