The three-dimensional camera mechanism 20 is electrically connected with the clamping assembly, the polishing assembly and the spraying assembly. After the two ends of the central shaft 8 are respectively placed on the corresponding arc surface seat 6, the cross-sectional position of the central shaft 8 and the rotor body 7 is actively identified by the three-dimensional camera mechanism 20, and then the specific coordinates are formed.

Compared with the prior art, the intelligent degree and operation efficiency during the rust-proof operation of the motor rotor are improved.

[0045] As a preferred embodiment in the embodiment, the clamping assembly is further provided with a guide assembly for improving the stability of the telescopic movement of the annular seat 9.

[0047] Embodiment Two

[0048] As Figures 8-11 shown, wherein the same or corresponding parts as in Embodiment One use corresponding reference numerals as in Embodiment One, for the sake of brevity, only the difference points from Embodiment One are described below. Embodiment Two differs from Embodiment One in that:

[0049] Further, as Figures 8-9 shown, two said mobile seats 4 are each further fixedly provided with two height-uniform guide rail assemblies 22, the guide rail assemblies 22 are provided with first sliding blocks 23, and the first sliding blocks 23 are provided with mounting frame assemblies 24 for supporting polishing assemblies or spraying assemblies;

[0050] The guide rail assemblies 22 include first guide rail pieces 221 provided at lower ends of the polishing assemblies and second guide rail pieces 222 provided at lower ends of the spraying assemblies;

[0051] The second guide rail pieces 222 include first sliding rails 2221 connected with the first sliding blocks 23, second sliding blocks 2222 fixedly provided at lower ends of the first sliding rails 2221, and second sliding rails 2223 matched with the second sliding blocks 2222;

[0052] The first sliding blocks 23 provided on the first guide rail pieces 221 and the first sliding blocks 23 provided on the first sliding rails 2221 are provided with connecting rods 2224 therebetween, outer sides of the first sliding blocks 23 are provided with first driving pieces 2225 for driving the first sliding blocks 23 to move, and outer sides of the first sliding rails 2221 are provided with second driving pieces 2226 for driving the first sliding rails 2221 to move.

[0053] In this embodiment, by providing the guide rail assemblies 22 including the first guide rail pieces 221 provided at lower ends of the polishing assemblies and the second guide rail pieces 222 provided at lower ends of the spraying assemblies, and the second guide rail pieces 222 including double-layer sliding rails, both synchronous movement of the polishing assemblies and the spraying assemblies and independent movement of the spraying assemblies can be realized, and the advantage of this arrangement is that when placing the motor rotor, the spraying assemblies can be independently moved to adjust the distance between the spraying assemblies and the polishing assemblies to adapt to motor rotors of different sizes; when processing the outer surface of the motor rotor, the polishing assemblies and the spraying assemblies can be simultaneously moved to realize polishing or spraying treatment of the motor rotor.

[0054] In detail, when the motor rotor is placed, the limiting of the connecting rod 2224 is cancelled first, so that the first sliding block 23 located on the first guide rail 221 and the first sliding block 23 arranged on the first sliding rail 2221 can relatively move, at the moment, the first driving part 2225 is controlled to work, the first driving part 2225 drives the first sliding block 23 on the first sliding rail 2221 to move to the appropriate position, then the connecting rod 2224 is limited, and the two different first sliding blocks 23 are fixed.

[0055] When the outer surface of the motor rotor is machined, the second driving part 2226 is controlled to work, the second driving part 2226 drives the first sliding rail 2221 and the first sliding block 23 at the upper end of the first sliding rail 2221 to move synchronously, the first sliding block 23 drives the first sliding block 23 on the first guide rail 221 to move through the connecting rod 2224, so as to drive the polishing assembly and the spraying assembly to move synchronously.

[0056] It should be noted that the connecting rod 2224 includes the connecting rods 22241 connected to the two first sliding blocks 23 respectively and the fixing rod 22242 for fixing and limiting the two connecting rods 22241, the other ends of the two connecting rods 22241 are hingedly connected to each other.

[0057] The pushing rods of the first driving part 2225 and the second driving part 2226 are fixedly connected to each other, so as to ensure that the first sliding rail 2221 and the first sliding block 23 at the upper end of the first sliding rail 2221 can move synchronously when the second driving part 2226 works.

[0058] Further, as shown in the figure, the mounting frame assembly 24 is arranged on the two first sliding blocks 23, the mounting frame assembly 24 includes the first frame body 241 and the second frame body 242 which are slidably arranged. Figures 8-10

[0059] The first frame body 241 includes the first support 2411 connected to one of the first sliding blocks 23, the first horizontal rod 2412 arranged on the first support 2411 and having the sliding groove 2413 opened at the upper end.

[0060] The second frame body 242 includes the second support 2421 connected to the other first sliding block 23, the second horizontal rod 2422 arranged on the second support 2421 and the sliding block 2423 arranged on the lower end of the second horizontal rod 2422 and matched with the sliding groove 2413.

[0061] In the embodiment, by arranging the mounting frame assembly 24 including the first frame body 241 and the second frame body 242, the relative movement of the two moving seats 4 is facilitated.

[0062] ​It should be noted that during operation, when the two movable seats 4 move relative to each other, the sliding block 2423 will slide inside the slide groove 2413, thereby changing the relative distance between the two movable seats 4.

[0063] Furthermore, such as Figures 10-11 As shown, the spraying assembly also includes a shielding member 33 for partially blocking the spray nozzle and connected to the first crossbar 2412, and an identification member 34 for identifying the recessed part of the motor rotor and connected to the U-shaped tube 30.

[0064] In this embodiment, by setting the shielding component 33 and the identification component 34 in conjunction with the spraying assembly, the spraying work of motor rotors of different sizes can be realized.

[0065] In detail, the shielding component 33 includes a support rod 331 connected to the first crossbar 2412 and a shielding plate 332 connected to the other end of the support rod 331. When the two moving seats 4 approach each other, the sliding block 2423 will slide inside the sliding groove 2413 and drive the shielding plate 332 to move towards the spray nozzle. After the clamping assembly completes the clamping work on the central shaft 8, the shielding plate 332 will also shield the spray nozzle that exceeds the length of the motor rotor. At this time, the paint can only be sprayed out from the unblocked spray nozzle and completely sprayed on the motor rotor, avoiding paint waste and adapting to the spraying work of motor rotors of different lengths.

[0066] The identification component 34 consists of a fixed plate 341 mounted on the U-shaped tube 30 and a sensor 342 (which can be a pressure sensor) connected to the fixed plate 341 near the motor rotor. Before spraying the motor rotor, the fixed plate 341 is moved so that the sensor 342 is attached to the side edge of the motor rotor. After the motor rotor rotates, when the sensor 342 is in the recessed part on the side of the motor rotor, the sensor 342 no longer contacts the motor rotor. The sensor 342 will then send a signal to the spraying assembly and stop the spraying of the paint to prevent the paint from being sprayed into the recessed part inside the motor rotor, which would be detrimental to subsequent processing.

[0067] Generally, when multiple coats are required, after completing the first coat, wait 10-15 minutes before applying the second coat to ensure that the paint film thickness reaches the preset range.

[0068] In some more specific implementations, the nozzle diameter is controlled between 0.42mm and 0.47mm, the angle between the nozzle's spray direction and the sprayed surface is 90° ± 10°, the distance between the nozzle and the outer surface of the motor rotor is controlled between 140mm and 290mm, the pressure inside the spray pipe 31 is controlled between 0.3MPa and 0.6MPa, and the moving speed of the nozzle relative to the outer surface of the motor rotor is 280mm / s ± 40mm / s.

[0069] Of course, it can be understood that the above setting parameters of the spraying pipe 31 and the spraying nozzle are only preferred examples of the embodiments of the present application, and other corresponding parameter ranges can also be selected according to actual conditions in actual production.

[0070] Working steps

[0071] After placing the two ends of the central shaft 8 on the corresponding arc seat 6, the three-dimensional camera mechanism 20 actively identifies the cross-sectional position of the central shaft 8 and the rotor body 7, and then forms specific coordinates, and controls the operation of the vertical electric sliding block 12 on both sides, and under the guidance of the corresponding vertical linear guide rail 11, moves the triangular chuck 10 on both sides to the coaxial height of the central shaft 8, and controls the operation of the telescopic air cylinder 13 on both sides, so that the telescopic end of the air cylinder is retracted, and the annular seat 9 is moved through the corresponding connecting plate 14, until the triangular chuck 10 is sleeved on the corresponding end of the central shaft 8, and then the triangular chuck 10 on both sides is clamped and fixed to the two ends of the central shaft 8, thereby realizing intelligent automatic clamping of different size motor rotors.
