Description

Technical Field

[0001] The utility model relates to the technical field of three-phase asynchronous motors, in particular to a circumferential grinding device for an end cover of a three-phase asynchronous motor. Background Art

[0002] A three-phase asynchronous motor is a type of electric motor that is powered by a 380V three-phase AC power supply (with a phase difference of 120 degrees). Since the rotor and stator rotating magnetic fields of the three-phase asynchronous motor rotate in the same direction but at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor.

[0003] The motor end cover is an important component of the three-phase asynchronous motor. Its surface needs to be ground during the processing. After searching, it was found that China Patent Publication No. CN217750731U discloses a motor end cover circular grinding device. The device controls the movement of the oil cylinder to change the position of the grinding disk, which is convenient for grinding different positions of the motor end cover circular grinding and improves the working range of the equipment. However, the grinding range of the motor end cover is not only one-sided, but also the reverse side needs to be ground. After the above device completes the grinding of one end of the end cover, it needs to be disassembled and reinstalled before grinding the other side, which increases the complexity of the grinding work and affects the efficiency. At the same time, the debris generated by the grinding splashes everywhere, causing inconvenience to the later cleaning, so it is necessary to improve the existing device to meet actual needs. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the utility model provides a three-phase asynchronous motor end cover circular grinding device, which has the advantages of first clamping and fixing the motor end cover, and then synchronously grinding both sides of the motor end cover through a grinding mechanism, thereby improving processing efficiency and avoiding flipping. At the same time, the debris generated during the grinding process is automatically cleaned and absorbed, thereby achieving the effect of automatic waste recovery, etc., thereby solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a three-phase asynchronous motor end cover circular grinding device, comprising a workbench, a movable groove is opened inside the workbench, and a rotating wheel is fixedly installed on the side, a positive and negative screw rod is rotatably installed on one side of the movable groove, and a guide rod is fixedly installed on the other side of the inside, a clamping plate is installed through the threaded outer surface of the positive and negative screw rod, a grinding mechanism is fixedly installed on the upper surface of the workbench, and a waste box is fixedly installed on the top side, a side-opening door is rotatably installed on the back of the waste box, and a vacuum cleaner is fixedly installed on the side, a duct is fixedly installed on the input end of the vacuum cleaner, and a dust hood is fixedly installed on the top of the duct.

[0008] Preferably, one end of the positive and negative threaded rod is fixedly connected to the inner side of the rotating wheel, and two sets of clamping plates are installed through the outer circumference relative to the thread, and the inner part of the other end of the clamping plate is slidably connected to the outer circumference of the guide rod.

[0009] Through the above technical scheme, the motor end cover is first placed between the two groups of clamps, and the rotating wheel is rotated so that the rotation of the rotating wheel drives the positive and negative screws to rotate synchronously. The rotation of the positive and negative screws drives the two groups of clamps on the outer peripheral surfaces to move relative to each other until the two groups of clamps clamp and fix the motor end cover. At the same time, the clamps slide synchronously on the outer peripheral surface of the guide rod, thereby increasing the stability of the movement of the clamps.

[0010] Preferably, the grinding mechanism includes a support frame fixedly mounted on the upper surface of the workbench, a limit rod fixedly mounted on the bottom end of the support frame, and a telescopic rod fixedly mounted on one side of the bottom end, a movable plate fixedly mounted on the top of the telescopic rod, a motor fixedly mounted on one side of the top of the movable plate, and the interior of the other side is slidably connected to the outer peripheral surface of the limit rod, and a sharpener is fixedly mounted on the rotor end of the motor.

[0011] Through the above technical solution, after the motor end cover is fixed, the telescopic rod is started, so that the telescopic rod drives the movable plate to drive the motor and the grinder to move downward until the grinder fits the surface of the motor end cover, and the motor is started to rotate the motor rotor end to drive the grinder to rotate, thereby achieving the effect of automatic grinding of the motor end cover.

[0012] Preferably, the grinding mechanisms are arranged in two groups relative to each other.

[0013] Through the above technical solution, by using two sets of grinding mechanisms arranged opposite to each other, the effect of synchronous grinding of both sides of the motor end cover is achieved, which improves the processing efficiency, saves the processing time, and avoids flipping.

[0014] Preferably, two groups of vacuum cleaners are relatively fixedly installed on the sides of the waste bin, a group of dust hoods are fixedly installed on the input end of each group of vacuum cleaners through a conduit, and the output end is fixedly connected to the inside of the waste bin through a conduit.

[0015] Through the above technical solution, a large amount of debris is generated when the grinding mechanism grinds the motor end cover. While processing, the vacuum cleaner is started so that the input end of the vacuum cleaner generates a strong suction force on the dust cover through the duct, thereby absorbing the debris generated in the grinding process, and then passing it into the waste box through the vacuum cleaner, thereby achieving the effect of automatic debris recovery.

[0016] Preferably, a side-opening door is installed on the back of the waste box by rotating through a hinge.

[0017] Through the above technical solution, the debris inside the waste box can be easily cleaned through the side door.

[0018] Compared with the prior art, the utility model provides a three-phase asynchronous motor end cover circumferential grinding device, which has the following beneficial effects:

[0019] 1. The utility model first places the motor end cover between two groups of clamping plates, rotates the rotating wheel, and causes the rotation of the rotating wheel to drive the positive and negative threaded screws to rotate synchronously. The rotation of the positive and negative threaded screws drives the two groups of clamping plates on the outer peripheral surfaces to move relative to each other until the two groups of clamping plates clamp and fix the motor end cover. At the same time, the clamping plates slide synchronously on the outer peripheral surface of the guide rod, thereby increasing the stability of the movement of the clamping plates.

[0020] 2. The utility model realizes the effect of automatic grinding of the motor end cover by starting the telescopic rod after the motor end cover is fixed, so that the telescopic rod drives the movable plate to drive the motor and the grinder to move downward until the grinder fits the surface of the motor end cover, and starting the motor so that the motor rotor end rotates to drive the grinder to rotate, thereby achieving the effect of automatic grinding of the motor end cover and avoiding flipping.

[0021] 3. The utility model generates a large amount of debris while grinding the motor end cover through the grinding mechanism. While processing, the vacuum cleaner is started so that the input end of the vacuum cleaner generates a strong suction force on the dust cover through the duct, thereby absorbing the debris generated during the grinding process, and then passing it into the waste box through the vacuum cleaner, thereby achieving the effect of automatic recovery of the debris.
