[0002] The motor train unit wheel-mounted brake disc is mainly installed on both sides of the wheel spoke plate and forms a brake friction pair with a brake pad, and is a component for braking the motor train unit. The surface of the motor train unit wheel needs to be subjected to paint spraying treatment to improve the surface performance and effectively prevent rusting or corrosion. However, during paint spraying, the mounting surface, the friction working surface and the bolt connecting hole of the wheel-mounted brake disc need to be strictly shielded to prevent paint adhesion and affect the friction coefficient of the brake disc.

[0038] The base 1 is provided with a main controller. The main controller adopts a PLC controller.

[0039] Working principle and working process:

[0040] In specific use, the staff injects the spraying paint into the paint tank 12, at this time, the winding wheel 45 completely winds up the pulling steel rope 46, so that the interval door 42 moves up, exposing the internal structure of the shielding cover 5, and the spraying rod 48 moves up following; then, the spraying time, baking time and cooling time are respectively input into the main controller, and the longest time is taken as the time node of the driving of the main motor. Then, the staff installs the bearing block 19 corresponding to the specification of the wheel to be sprayed by bolts at the output end of the hydraulic telescopic column 18, and installs the first baffle 28 on the first mounting ring 35 and the second baffle 29 on the second mounting ring 37 by bolts. When installing, the first mounting ring 35 and the second mounting ring 37 can be manually rotated, and the sizes of the first baffle 28 and the second baffle 29 are consistent with the size of the brake disc of the wheel.

[0041] The wheel is placed in the load arc groove 20 of the bearing block 19 in a hoisting manner, at this time, the turnover clamping type shielding assembly 3 in the feeding area 7 is opposite to the bearing block 19, the telescopic direction of the bidirectional telescopic column 25 is along the horizontal direction, and the bidirectional telescopic column 25 is in the elongated state. Then, the hydraulic telescopic column 18 is started, so that the bearing block 19 drives the wheel to move towards the main rotating column 2. When the wheel moves to be concentric with the accommodation through hole, the bidirectional telescopic column 25 is contracted, so that the power clamping mechanism 26 and the follow-up clamping mechanism 27 move relatively, until the first baffle 28 and the second baffle 29 are respectively pressed and fitted on the brake discs on the two sides of the wheel. At this time, the electromagnetic rings on the first baffle 28 and the second baffle 29 are electrified to generate magnetism, and are adsorbed on the wheel. The first baffle 28 and the second baffle 29 magnetically attracted to the wheel form an integral whole with the wheel, increasing the stability of the wheel clamped by the power clamping mechanism 26 and the follow-up clamping mechanism 27. Then, the hydraulic telescopic column 18 is contracted, and the bearing block 19 is reset to receive the next wheel to be sprayed. In this process, the cleaning telescopic plate 14 is adaptively telescopic, so that the bristles 15 are fitted on the edge of the wheel.

[0042] The wheel clamped by the power clamping mechanism 26 and the follow-up clamping mechanism 27 is in a vertical state. The rotating motor 31 is started to drive the power wheel 32 to rotate, the power wheel 32 drives the rotating ring 33 to rotate through the transmission belt 34, and then drives the first mounting ring 35 to rotate. The first baffle 28 mounted on the first mounting ring 35 drives the wheel to rotate, so that the first baffle 28, the second baffle 29 and the wheel rotate as a whole. The second mounting ring 37 follows the second baffle 29 to rotate on the follow-up frame 36. In the process of rotating the wheel, the bristles 15 continuously clean the impurities on the edge of the wheel. At the same time, the air pump 17 is started to blow air to the two sides of the wheel through the inclined air blowing port 16, blowing off the dust thereon. The swept impurities fall into the base 1 through the dust collecting groove 11, avoiding the influence of the impurities on the wheel on the spraying effect. After cleaning, the rotating motor 31 stops rotating, and the wheel is in a state of waiting to be sprayed.

[0043] The main controller controls the main power motor to start, and the turnover clamping type shielding assembly 3 clamps the wheel to turn to the spraying area 8, at the same time, the rotating motor 24 starts to rotate, the bidirectional telescopic column 25 rotates 90 degrees, the follow-up clamping mechanism 27 is in the lower position, the power clamping mechanism 26 is in the upper position, and the wheel is in a horizontal state, and the weight of the wheel is mainly borne by the follow-up clamping mechanism 27; at this time, the spray head 40 in the middle position is opposite to the wheel rim, and the two inclined spray heads 40 are opposite to the two sides of the wheel spoke respectively; then the winding motor 44 starts, the winding wheel 45 rotates to release the pulling steel wire 46, under the action of the gravity of the interval door 42, the three interval doors 42 between the feeding area 7 and the spraying area 8, the spraying area 8 and the baking area 9 and the baking area 9 and the discharging area 10 fall down at the same time, and the feeding area 7, the spraying area 8, the baking area 9 and the discharging area 10 are isolated, the spray rod 48 moves downward, the nozzle of the spray rod 48 moves to the inside of the wheel, the timing control module of the main controller starts to count the paint spraying time, the liquid pump 39 and the suction pump 47 start at the same time, the liquid pump 39 draws paint to the spraying frame 38 and sprays out through the spray head 40, the three spray heads 40 spray paint to the wheel rim and the two sides of the wheel spoke respectively, the suction pump 47 draws paint to the spray rod 48 and sprays out through the nozzle, and the spray rod 48 sprays paint to the inside of the wheel; in this process, the rotating motor 31 starts to rotate the wheel again to ensure the uniformity of the paint spraying, and the excess paint can directly fall into the paint tank 12; after the paint spraying time is up, the liquid pump 39, the suction pump 47 and the rotating motor 31 stop working, and the main power motor is waiting for response.

[0044] When the timing control module of the main controller issues an instruction, the winding motor 44 starts again, the winding wheel 45 winds the pulling steel wire 46 to lift the interval door 42, and then the main power motor starts, the main rotating column 2 rotates 90 degrees, and the sprayed wheel is transferred to the baking area 9, and then the winding wheel 45 unwinds the pulling steel wire 46 again to lower the interval door 42 to isolate the spraying area 8 and the baking area 9, and after the sprayed wheel enters the baking area 9, the heating rod 23 and the baking rod 41 start to work, and the wheel is heated at a high temperature to accelerate the drying and curing of the paint on the surface of the wheel until the set baking time is reached, and then the heating rod 23 and the baking rod 41 stop working.

[0045] When the timing control module of the main controller issues an instruction again, the winding wheel 45 winds the pulling steel wire 46 to lift the interval door 42, and then the main power motor starts, the main rotating column 2 rotates 90 degrees again, and the rotating motor 24 starts to rotate, so that the turnover clamping type shielding assembly 3 clamps the wheel to turn to the discharging area 10 and be in a vertical state; at this time, the timing control module of the main controller counts the cooling time to cool the wheel naturally, and after the wheel is completely cooled, the bidirectional telescopic column 25 operates, the power clamping mechanism 26 and the follow-up clamping mechanism 27 simultaneously release the wheel, the wheel naturally falls onto the discharging slope 21 and rolls onto the conveying belt of the subsequent process through the discharging slope 21, and the discharging is completed.

[0046] The above process is the operation flow of a single wheel sequentially passing through the loading area 7, the spraying area 8, the baking area 9 and the unloading area 10 under the support of the turnover clamping type shielding assembly 3. In actual use, four groups of the turnover clamping type shielding assembly 3 work simultaneously. The longest time among the spraying time, the baking time and the cooling time is taken as the time node of the driving of the main motor. The hydraulic telescopic column 18, the air pump 17, the winding motor 44, the suction pump 47, the liquid pumping pump 39, the heating rod 23, the baking rod 41 and the turnover clamping type shielding assembly 3 work synchronously to operate the whole process of loading, spraying, baking, cooling and unloading of the wheel, which is highly automated and improves the spraying efficiency.

[0047] It is worth mentioning that the control program setting in the main controller and the telescopic amount of the hydraulic telescopic column 18 can be set according to the requirements. The use of the spray head 40, the spray rod 48, the heating rod 23 and the baking rod 41 is the prior art, which will not be described here.
