DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0028] like Figure 1 and Figure 2 As shown, a motor shaft maintenance device includes a maintenance platform 1, a first fixed plate 11, a clamping and rotating assembly, a telescopic assembly, a baking oil device 23 (which belongs to the prior art and its principle is not described here, specifically an acetylene spray gun), an electric cylinder 24 and a grinding assembly.

[0029] The first fixing plate 11 is arranged on the maintenance platform 1;

[0030] The clamping and rotating assembly and the telescopic assembly are both arranged on the first fixed plate 11;

[0031] The oil roasting device 23 and the electric cylinder 24 are spaced apart on the telescopic assembly;

[0032] The grinding assembly is connected to an electric cylinder 24 .

[0033] Further refinement of the embodiment of the present invention is as follows: Figure 1 As shown, the clamping rotation assembly includes a servo motor 111 and an electric chuck 112 . The servo motor 111 is provided on the first fixed plate 11 . The servo motor 111 is connected to the electric chuck 112 . Specifically, the electric chuck 112 is an electric four-jaw chuck 112 .

[0034] Further refinement of the embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, the telescopic assembly includes a multi-stage telescopic member 21 and a mounting plate 22. The multi-stage telescopic member 21 is provided on the first fixed plate 11. The multi-stage telescopic member 21 is connected to the mounting plate 22. The oil baking equipment 23 and the electric cylinder 24 are spaced apart on the mounting plate 22.

[0035] Further refinement of the embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, the grinding assembly includes a grinding motor 25 and a grinding wheel 26 . The electric cylinder 24 is connected to the grinding motor 25 , and the grinding motor 25 is connected to the grinding wheel 26 .

[0036] Further refinement of the embodiment of the present invention is as follows: Figure 1As shown, a collection box 13 is placed on the maintenance table 1 and a filter is movably provided inside the collection box 13, which is not shown in the figure. The collection box 13 can collect the debris generated during the baking oil and polishing process, and at the same time, the filter can be used to effectively separate the small amount of dripping repair materials from the debris.

[0037] It should be noted that the servo motor 111, the multi-stage telescopic member 21, the oil-roasting device 23, the electric cylinder 24 and the polishing motor 25 are all electrically connected to the controller, which is not shown in the figure.

[0038] The workflow of this utility model:

[0039] First, one end of the motor shaft is inserted into the electric chuck 112, and the electric chuck 112 is used to clamp and fix the motor shaft. After the clamping and fixing are completed, the controller controls the servo motor 111 to drive the motor shaft to rotate at a constant speed. When the motor shaft is driven to rotate, the controller controls the multi-stage telescopic member 21 to work and then drives the mounting plate 22 to perform horizontal intermittent motion. At the same time, the oiling device 23 starts to work and starts to spray acetylene gas to effectively clean the oil stains on the surface of the motor shaft. As the oiling process is carried out, when there is no longer any spark splashing on the surface of the motor shaft, the oiling is completed, and the first step of repairing the worn motor shaft surface can be automatically completed.

[0040] After the oiling process on the surface of the motor shaft is completed, the motor shaft still maintains a uniform rotation state, and the multi-stage telescopic part 21 continues to make uniform horizontal intermittent motion, but the oiling equipment 23 stops working at this time, and then the controller controls the electric cylinder 24 to move to drive the grinding wheel 26 to contact the local surface of the motor shaft. At the same time, the controller controls the grinding motor 25 to work and drive the grinding wheel 26 to rotate at high speed. At this time, the grinding wheel 26 will contact the local surface of the motor shaft and realize a circle of grinding of its local surface. Subsequently, the electric cylinder 24 drives the grinding wheel 26 to adjust up and down according to a pre-set program and then cooperates with the uniform intermittent drive of the multi-stage telescopic part 21 to realize comprehensive grinding of the motor shaft. After the surface grinding of the motor shaft is completed, the multi-stage telescopic part 21 drives the mounting plate 22 to move back to the initial position (as shown in the attached manual). Figure 1 As shown in ), during this process, the grinding motor 25 stops working and the electric cylinder 24 contracts, and the second step of repairing the worn motor shaft surface can be automatically completed at this time;

[0041] Then the repair material can be manually applied to proceed to the third step of repair. During the application of the repair material, the motor shaft stops rotating. After completing the above three steps of repair and waiting for the repair material to solidify, the motor shaft can be disassembled and then the motor shaft can be used again.

[0042] Compared with the existing technology, this device does not require manual oiling and polishing of the worn motor shaft surface. It is completed automatically and the treatment effect is comprehensive. It only requires manual application of repair materials. This greatly reduces the labor intensity of manual operation, realizes semi-automatic processing, and improves the efficiency of motor shaft maintenance and repair.

[0043] In some embodiments, as Figure 1 As shown, the maintenance table 1 is also provided with a second fixed plate 12, and an electric push rod 31 is provided on the second fixed plate 12, and the electric push rod 31 is connected to the driving motor 32, and the driving motor 32 is connected to the disc 33. Four independently controlled electromagnets 34 are arranged on the circumference of the disc 33, and one of the electromagnets 34 is directly opposite to the electric chuck 112; in this embodiment, after completing the repair operation of one motor shaft, the controller immediately controls the electric push rod 31 to work and then drive the disc 33 to approach the other end of the motor shaft (at this time, the telescopic component drives the baking oil equipment and the polishing component to be in a retracted state so as not to interfere with the electromagnetic adsorption of the motor shaft). At this time, the electromagnet 34 at the bottom end of the disc 33 is independently energized to achieve firm adsorption of the motor shaft. After electromagnetic adsorption, the electric chuck 112 first releases the clamping of the motor shaft, and then the electric push rod 31 drives the motor shaft away from the processing and repair area, and then the installation and repair processing process of the next motor shaft can be started;

[0044] When the electromagnetic adsorption of a motor shaft is completed, the motor 32 is driven to work to realize the equal-angle rotation of the disc 33, and then the electromagnet 34 of the next motor shaft that has not been adsorbed will rotate to the bottom of the disc 33. At this time, the automatic transfer of the motor shaft after processing can be realized and preparations can be made for the automatic transfer of the next motor shaft to be repaired. In this way, there is no need to wait for the previous motor shaft repair material to be completely solidified before starting the next round of repair work.

[0045] Further optimization of the above embodiment scheme, such as Figure 1 As shown, the maintenance table 1 is provided with a blow box 41 with a hollow interior, and the blow box 41 is provided with a hot air blower 42 connected to the interior thereof and a plurality of air holes are opened on the blow box 41, which are not shown in the figure; as the above process is continuously carried out, the motor shafts are successively adsorbed on the plurality of electromagnets 34 (in the subsequent process of adsorbing the motor shaft, the already adsorbed motor shaft will not interfere with the electromagnetic adsorption operation), and then the hot air blower 42 works under the control of the controller and then blows out hot air from the plurality of air holes synchronously to speed up the curing speed of the repair material applied on the surface of the motor shaft. In addition, one person is equipped to perform the power-off and unloading process of the motor shaft after the curing is completed, and the plurality of electromagnets 34 can complete the power on and off independently.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
