Description

Technical Field

[0001] The invention relates to the technical field of motor end cover processing, in particular to a modular motor end cover precision processing device. Background Art

[0002] The motor end cover is a cover installed on the end face of the motor casing. Its quality directly affects the quality of the motor. In order to ensure the installation accuracy of the motor end cover, it is necessary to tap and grind the end face and other places. The motor will generate various forces and vibrations during operation, and the motor end cover needs to have sufficient strength to withstand these forces. Therefore, when producing and processing the motor end cover, some convex strips will be set on the inner wall of the motor end cover. The convex strips are used to increase the thickness and rigidity of the end cover, so that it can better resist the stress and deformation generated during the operation of the motor to ensure the normal operation of the motor. The motor end cover usually has irregular curved surfaces and corners.

[0003] The presence of inner wall convex strips, irregular curved surfaces and corners changes the flatness of the motor end cover, which hinders the grinding rod from contacting these areas during grinding, especially in the corner area and concave area. The existing rigid structure of the grinding rod is not flexible enough when adapting to complex curved surfaces or corners, and it is difficult to effectively fit the inner wall for grinding, thus forming a grinding blind area, which makes the overall grinding effect poor and leads to incomplete grinding. For this reason, we propose a modular motor end cover precision processing device. Summary of the invention

[0012] In some embodiments, a limiting structure is provided between the first connecting shaft and the bearing seat, and between the second connecting shaft and the bearing seat, and the limiting structure is used to limit the position of the angle deflection mechanism after the angle is deflected.

[0013] In some embodiments, the limiting structure includes a protrusion and a movable groove, the outer walls of the first connecting shaft and the second connecting shaft are both fixed with protrusions, the movable groove is opened on the inner wall of the bearing seat, and the length of the movable groove is not less than one-fourth of the inner circumference of the bearing seat, the outer wall of the protrusion is opened with a receiving groove, the interior of the receiving groove is connected with a spring, the end of the spring is connected with a positioning column, and the inner ends of the movable groove are opened with positioning grooves that match the ends of the positioning column.

[0019] 2. Better adapt to the complex shape of the motor end cover: The motor end cover usually has irregular curves and corners. The grinding rod with a deflectable angle can flexibly fit these curves. For the grooves and protrusions inside the motor end cover, the grinding rod with a deflectable angle can go deep into these areas for fine grinding, ensuring that there will be no omissions or uneven grinding during the grinding process, ensuring that each part can be fully polished, greatly improving the adaptability to workpieces of different shapes.

[0020] 3. Reduce the difficulty of operation and labor intensity: For operators, the grinding rod with deflectable angle is easier to operate and control. They can easily adjust the angle of the grinding rod according to actual conditions without frequently adjusting their posture, which reduces the difficulty of operation and labor intensity.

[0044] Through the above, when it is necessary to perform a grinding operation on the motor end cover, the staff manually rotates the threaded rod 434, and uses the threaded rod 434 to push the connecting block 433 to move, so that the second hemispherical gear 429 is meshed and connected to the first hemispherical gear 428, and uses the second adjustment mechanism 45 to disconnect the tapping module 44 from the driving end of the grinding module 41, and then the motor 411 can be started, and the output end of the motor 411 can be used to drive the first connecting shaft 412 to rotate, and then the first hemispherical gear 428 can be used to drive the meshed second hemispherical gear 429 to rotate, so that the grinding rod 414 installed at the end of the second connecting shaft 413 can be driven to perform a grinding operation.

[0046] Secondly, a manual handle can be connected to the adjustment gear 4231 for manual adjustment, or a small motor can be installed to perform automatic adjustment during the grinding operation.

[0047] See also Figure 5 and Figure 6 As shown, first guide grooves 432 are provided on both sides of the interior of the adjustment groove 431, and first guide bars 435 are fixed on both sides of the connecting block 433.
