Technical Field

[0001] The invention relates to the technical field of automobile wheel hub spraying, in particular to an automobile wheel hub spraying device with a dust cleaning function. Background Art

[0002] The automobile wheel hub is the part in the center of the wheel where the axle is installed. During the actual driving of the vehicle, pollutants are easily attached to the automobile wheel hub, which corrodes the automobile wheel hub and reduces the service life of the automobile wheel hub. In order to improve the service life and wear resistance of the automobile wheel hub, it is necessary to paint the automobile wheel hub during production, thereby improving the quality and service life of the automobile wheel hub.

[0003] However, when spraying the automobile wheel hub, since the automobile wheel hub is stored exposed to the air, dust will be attached to its surface, making it difficult for the spray paint to stably adhere to the surface of the automobile wheel hub during the spraying process. In addition, due to the complex shape design of the automobile wheel hub, the existing spraying is carried out manually, which is easy to cause uneven spraying, affecting the quality of the coating, consuming a lot of time and energy, and having low work efficiency. If no attention is paid to protection during operation, the spray paint may be inhaled, affecting the health of the operator. In addition, directly placing the wheel hub on a conical support table will cause the wheel hub to vibrate when encountering vibration, affecting the spraying effect. Summary of the invention

[0040] like Figure 9-Figure 18 As shown, in order to spray the wheel hub comprehensively, the spraying device is located on the outer surface of the frame of the annular conveying component 1, and the automobile wheel hub that needs to be sprayed is turned over for spraying. The spraying device includes a turning mechanism, a clamping mechanism and a spraying mechanism.

[0043] Specifically, in order to drive the wheel hub to rotate and facilitate all-round spraying, a bracket 7 is fixedly installed on the outer surface of a limiting ring groove 61, and a rotating motor 71 is fixedly installed on the outer surface of the bracket 7. A driving sleeve 72 is slidably inserted at one end of the output shaft of the rotating motor 71, and a switching electromagnet 73 is fixedly installed at one end of the output shaft of the rotating motor 71.

[0047] Working principle: After the staff sleeves the sprayed wheel hub on the fixed sleeve 2, the lower end of the fixed sleeve 2 is plugged into one end of the plug-in rod 21 on the slider of the annular conveying component 1 below, and the fixed electromagnet 22 at the upper end is energized to adsorb the plug-in rod 21 at the upper end, so that the fixed sleeve 2 can be placed stably. Then, the fixed electromagnet 22 at the upper end is powered off, and the plug-in rod 21 is reset under the action of the spring and plugged into the upper inner wall of the fixed sleeve 2. At the same time, the pushing handle 33 in the fixed sleeve 2 is squeezed. After the pushing handle 33 is lowered, the deflection connecting rod 31 is pushed, and the reset spring 32 is compressed. The deflection connecting rod 31 pushes the support plate 3 to move outward to support the inner wall of the wheel hub, thereby completing the fixation of the wheel hub. After the annular conveying component 1 is started, it drives the fixed sleeve 2 to move to one side of the connecting frame 4, and can push the support frame 42 to move by pushing the hydraulic cylinder 41, so that the telescopic connecting rod 44 is close to the side of the wheel hub that needs to be cleaned, and the dust suction hose 47 on the conveying trough body 46 contacts one side of the wheel hub, and the fan 48 is started. The suction force generated adsorbs the outer surface of the wheel hub, and after the telescopic motor 43 is started, the two telescopic connecting rods 44 are driven to rotate synchronously in opposite directions through the transmission of the bevel gear, and the telescopic connecting rod 44 is driven to unfold, which can drive the conveying trough body 46 to move. After the dust suction hose 47 rubs the outer surface of the wheel hub, it is convenient to clean the dust on the wheel hub, and it is convenient to adsorb the dust. The dust is transported into the dust collector to complete the cleaning of the wheel hub; After the conveying trough body 46 is reset, the wheel hub that has been cleaned is conveyed to the center of the limiting ring frame 5, and the limiting ring groove 61 is pushed by the telescopic hydraulic cylinder 6 to be close to the fixed sleeve 2, and the clamping clamp 63 clamps the fixed sleeve 2. At the same time, the block on the clamping clamp 63 can be inserted into the groove of the fixed sleeve 2, and plugged into the groove on the pushing handle 33 in the fixed sleeve 2 to fix the pushing handle 33. After the fixed electromagnet 22 is energized, the plug-in rod 21 is adsorbed to release the plug-in connection with the fixed sleeve 2; After the switching electromagnet 73 is energized, the driving sleeve 72 is magnetically connected, and the driving sleeve 72 is driven to rise. After the driving bevel gear 76 on the driving sleeve 72 is meshed with the bevel gear on the transmission gear set 81, the rotating motor 71 is started to drive the driving sleeve 72 to rotate, thereby driving the transmission gear set 81 to rotate, and driving the locking gear ring 8 in one half gear ring 62 to rotate toward the other half gear ring 62, driving the lock handle 82 to be inserted into the inside of the other half gear ring 62, squeezing the limit groove 84. The fixing frame 85, after the fixing frame 85 moves in the limiting groove 84, the clamping block 86 is squeezed by the fixing frame 85, clamps the lock handle 82, and can fix the locking toothed ring 8. At the same time, the movement of the fixing frame 85 can drive the fixed crank 87 to deflect and then move the slideway of the slideway block 83, so that one end of the fixed crank 87 is inserted into the slideway groove of the slideway block 83, fixes the fixing frame 85, and keeps the clamping block 86 in a limiting state, thereby limiting the position of the locking toothed ring 8. After the hydraulic cylinder 91 is adjusted to push the spray gun 92 close to the wheel hub and positioned above the wheel hub, the switching electromagnet 73 is powered off and reset under the action of the connecting spring 74. After the driving gear 75 is meshed with the semi-toothed ring 62, the semi-toothed ring 62 is driven to rotate on the limiting ring groove 61, driving the clamped fixed sleeve 2 to rotate, and the spray gun 92 sprays the spray material in the storage component 9 onto the outer surface of the wheel hub. After the upper surface of the wheel hub is sprayed, the flipping motor 51 is started, driving the mobile gear ring 52 to rotate in the limiting ring frame 5, driving the clamped fixed sleeve 2 with the wheel hub to rotate, driving the fixed sleeve 2 to flip 90°, and then spraying the outer side surface of the wheel hub. After the spraying is completed, it rotates 90° again. After the lower surface of the wheel hub faces upward, the lower surface of the wheel hub is sprayed. After the spraying is completed, the fixed sleeve 2 is reset. When it is necessary to release the fixation of the fixed crank 87, the fixed frame 85 continues to move inward, driving the fixed crank 87 to move along the groove of the slide block 83 to the outer surface of one side of the slide block 83. Under the action of the tension spring 88, the fixed crank 87 and the fixed frame 85 are reset, and the fixation of the locking handle 82 can be released. After the fixed electromagnet 22 is powered off, the plug-in rod 21 is plugged into the fixed sleeve 2. After the fixed sleeve 2 is fixed, the telescopic hydraulic cylinder 6 is reset, and the fixed sleeve 2 is driven to be transported as the annular conveying component 1 moves.
