Description

Technical Field

[0001] This utility model relates to the field of motor component processing equipment technology, and more specifically to a device for processing the end cover temperature sensor mounting hole of an asynchronous motor. Background Technology

[0002] The rear end cover of existing asynchronous motors is generally fixed to the rear end of the motor housing with bolts. At the same time, the rear end of the rotor shaft of the asynchronous motor extends out of the central through hole of the rear end cover and fixes the heat dissipation impeller. During use, the rotor rotates and drives the heat dissipation impeller to dissipate heat. However, the temperature inside the housing will rise during operation, which needs to be monitored in time to prevent damage due to excessive internal temperature. However, existing asynchronous motors do not have a device to detect the internal temperature. Therefore, a temperature sensor can be installed to detect the temperature inside the housing.

[0003] Therefore, it is necessary to drill holes in the rear end cover to install a temperature sensor. The existing method is to manually place the rear end cover on the drilling machine for processing. This requires manual placement of the rear end cover on the machine, fixing the pressure block with bolts to secure it, processing, and then loosening the bolts so that the pressure block no longer presses against the rear end cover, and then manually unloading the material. This method involves a large amount of manual labor, is cumbersome, and affects processing efficiency. Utility Model Content

The top end of the push rod of the lifting cylinder 40 extends out of the top surface of the horizontal connecting plate 13 and is fixed to a lifting plate 41. A motor frame 42 is fixed to the top surface of the lifting plate 41. The motor frame 42 is located above the top surface of the top plate of the frame 10. A rotary servo motor 43 is fixed to the bottom surface of the top plate of the motor frame 42. The top end of the output shaft of the rotary servo motor 43 extends out of the top surface of the top plate of the motor frame 42 and is fixed with a rotating arm 44.

[0028] Furthermore, a fixing frame 50 is fixed on the top surface of the top plate of the frame 10 on the left side of the processing fixing seat 20. A drilling power head 51 (which is a conventional structure and will not be described in detail here) is fixed on the fixing frame 50. The motor end cover 100 to be processed is placed on the top surface of the processing fixing seat 20. The positioning post 21 is inserted into the corresponding positioning through hole formed at the edge of the motor end cover 100. The outer side wall of the positioning post 21 is close to the inner side wall of the corresponding positioning through hole. The drill bit at the bottom of the drilling power head 51 faces the top surface of the top plate on the left side of the motor end cover 100 to be processed.

[0029] Furthermore, multiple clamping rotary cylinders 15 are fixed on the top surface of the top plate of the frame 10 around the processing fixed seat 20. The top end of the push rod of the clamping rotary cylinder 15 is fixed with the bottom surface of the end of the clamping block 151 pressing against the top surface of the edge of the motor end cover 100 to be processed.

[0030] Furthermore, the top plate of the processing fixture 20 has a central threaded through hole formed in its center. A central support threaded post 22 is threaded into the corresponding central threaded through hole. The top end of the central support threaded post 22 extends out of the top surface of the top plate of the processing fixture 20, and its top surface presses against the bottom end surface of the extension formed in the center of the bottom surface of the top plate of the motor end cover 100 to be processed. The height of its top surface can be changed by rotating the central support threaded post 22, allowing its top surface to press against the bottom end surface of the extension formed in the center of the bottom surface of the top plate of the motor end cover 100 placed on the top plate of the processing fixture 20.

[0031] The bottom surface of the intermediate support screw post 22 has a downwardly extending protrusion 221 formed in the middle. The compression spring 222 is inserted into the protrusion 221. The top end of the compression spring 222 presses against the bottom end surface of the intermediate support screw post 222, and the bottom end of the compression spring 222 presses against the top surface of the top plate of the frame 10.

[0032] The bottom of the drilling power head 51 has a drill bit facing the top plate of the processing fixing seat 20 directly below the top plate of the motor end cover 100 to be processed. A waste discharge through hole 23 is formed on the top plate of the frame 10 corresponding to the waste discharge through hole 23. A lower through hole 17 is formed on the top plate of the frame 10 below the lower through hole 17. A waste receiving cart 80 is placed on the ground below the lower through hole 17.

[0033] In this embodiment, all hydraulic cylinders are connected to the corresponding control valves on the hydraulic system via connecting pipes. The operation is controlled by opening and closing the control valves. All electrical components are electrically connected to the control host via electrical connection lines. The operation is controlled by the control host. This is a conventional structure and will not be described in detail here. The drilling power head 51 in this embodiment is also a commercially available product and will not be described in detail here.

[0034] In this embodiment, the motor end cover 100 to be processed is first manually placed on the top surface of the top plate of the end cover placement seat 30. The corresponding positioning pin 31 is inserted into the corresponding positioning through hole on the side of the motor end cover 100. Then, the rotary servo motor 43 is controlled by the host to run (its initial position is that the rotating arm 44 extends forward, and at the same time, the proximity switch 1 at the front senses the sensing pin 441), causing the rotating arm 44 to rotate 90° counterclockwise to the right. The proximity switch 1 on the right senses the sensing pin 441, indicating that it has moved into place. At this time, the electromagnet block 46 is above the motor end cover 100 placed on the end cover placement seat 30. Then, the push rod of the lifting cylinder 40 is retracted, and the electromagnet block 46 is activated to attract and fix the motor end cover 100. Then, the push rod of the lifting cylinder 40 is retracted. The rotating arm 44 is rotated 180° clockwise by the rotary servo motor 43, causing the proximity switch 1 on the left to sense the sensing post 441, indicating that it has moved into position. Then, the push rod of the lifting cylinder 40 retracts, placing the motor end cover 100 on the processing fixture 20, with its positioning post 21 inserted into the corresponding positioning through hole. Then, the electromagnet block 46 closes, the push rod of the lifting cylinder 40 is raised, and the rotating arm 44 is rotated 90° counterclockwise by the rotary servo motor 43, causing the proximity switch 1 at the front to sense the sensing post 441, indicating that it has moved to the initial position. At the same time, all the clamping rotary cylinders 15 operate, rotating and pressing down the clamping block 151, pressing the bottom surface of the end of the clamping block 151 against the top surface of the edge of the motor end cover 100 to be processed, thus achieving clamping and fixing.

[0035] Then, the drilling power head 51 operates, causing the drill bit to rotate and descend, drilling a hole in the top surface of the top plate on the left side of the motor end cover 100. After completion, everything returns to its original position. Some of the debris from the drilling process will fall into the waste material receiving cart 80, and some will remain on the top surface of the processing fixed seat 20 and the top surface of the top plate of the frame 10. These need to be handled manually during subsequent cleaning.

[0036] Then, the rotary servo motor 43 runs, causing the rotary arm 44 to rotate 90° clockwise and face the machining fixed seat 20. After removing the machined motor end cover 100 from it, it rotates 90° clockwise again and moves it above the unloading rack 60. Then it is lowered to complete the unloading. Finally, it rotates 180° counterclockwise to return to the starting position.

[0037] This example is easy to operate, highly automated, produces good processing results, is highly efficient, and greatly reduces manual labor.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
