The function of the axle is to bear the load of the car and maintain the normal driving of the car on the road. In order to protect the axle from rust, the axle needs to be sprayed as a whole after processing and assembly. At present, spraying is usually carried out while the axle is transported along the processing line. The axle is prone to shaking during transportation, resulting in unstable painting effect. In addition, the spraying method is usually to spray one side first and then the other side, which easily leads to uneven paint thickness on different sides of the axle, affecting the protection quality of the axle.

DETAILED DESCRIPTION

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1 As shown, a vehicle axle painting device comprises a base 1, and upright frames 2 are respectively arranged on the left and right sides of the upper end of the base 1; the upper part of the upright frame 2 is threadedly connected with positioning studs 3; the positioning studs 3 are arranged along the left and right directions and the two positioning studs 3 correspond to each other coaxially; a circumferential painting mechanism and a paint supply component are arranged above the base 1; the circumferential painting mechanism moves on the base 1 through a displacement control mechanism;

[0020] like Figure 2 As shown, the circumferential paint spraying mechanism includes a support seat 4 arranged above the base 1; the support seat 4 is between the two upright frames 2; two semi-circular liquid guide shells 5 are arranged above the support seat 4; the two liquid guide shells 5 are correspondingly abutted one above and one below to form a ring structure; one end of the two liquid guide shells 5 is hingedly connected, and the other end is connected by a lock 6; the lower liquid guide shell 5 is connected to the support seat 4 through a connecting frame 7; the liquid guide shell 5 is coaxially corresponding to the positioning stud 3; a plurality of liquid outlet joints 8 are fixed on the inner annular surface of the liquid guide shell 5 along the circumferential direction; the liquid outlet joint 8 is connected to the internal cavity of the liquid guide shell 5; a diffusion nozzle 9 is threadedly connected to the liquid outlet joint 8;

[0021] like Figure 1-2 As shown, the paint supply assembly includes a paint storage tank 10 fixed on the upper end of the base 1, and two liquid pumps 11 fixed on the upper end of the support base 4; the liquid extraction ports of the liquid extraction pumps 11 are connected to the paint storage tank 10 through suction hoses 12; the liquid discharge ports of the liquid extraction pumps 11 are connected to the internal cavities of the two liquid guide shells 5 one by one through discharge hoses 13;

[0022] like Figure 1 As shown, the displacement control mechanism includes a mounting seat 14 fixed on the upper end of the base 1; the mounting seat 14 is rotatably connected to an adjusting screw rod 15 on the front side, and is fixedly connected to a guide slide rod 16 on the rear side; the adjusting screw rod 15 and the guide slide rod 16 are both arranged in the left and right directions; the support seat 4 is threadedly connected to the adjusting screw rod 15 and is slidably connected to the guide slide rod 16; a control motor 17 is fixed on the base 1; and the output end of the control motor 17 is coaxially fixed to the adjusting screw rod 15.

[0023] First, release the connection between the upper liquid-conducting shell 5 and the lock 6 of the lower liquid-conducting shell 5, hinge and flip the upper liquid-conducting shell 5, remove the obstruction on the upper end of the lower liquid-conducting shell 5, and then use a lifting device to suspend the axle between the two vertical frames 2, and then clamp the axle firmly by screwing the positioning studs 3 (there will be reserved holes on both sides of the axle for installing wheels), and then re-fasten and lock the upper liquid-conducting shell 5 to the lower liquid-conducting shell 5. At this time, the two liquid-conducting shells 5 can be mounted on the outside of the axle.

[0024] After completing the above preparations, start the liquid extraction pump 11 and the control motor 17. The liquid extraction pump 11 extracts the paint liquid in the paint storage tank 10 through the suction hose 12, and then injects it into the respectively connected liquid guide shells 5 through the discharge hose 13, and then enters the diffusion nozzle 9 with the help of the liquid outlet joint 8, and is sprayed from the diffusion nozzle 9 to the surface of the axle. Through the multiple diffusion nozzles 9 arranged circumferentially, the circumferential sides of the axle can be perfectly sprayed to avoid the existence of dead corners in spraying; at the same time, the control motor 17 drives the adjusting screw 15 to rotate, and then drives the support seat 4 to move left and right, and the liquid guide shell 5 can move from one end to the other end along the direction of the axle to complete the complete spraying of the axle surface.

[0025] In the above process, the paint spraying is controlled by the power of the liquid pump 11, so that the paint can be stably and evenly discharged. In combination with the control motor 17 to control the smooth movement of the liquid guide shell 5, the paint surface covering the entire axle after spraying can have sufficient uniformity. In addition, it should be noted that the speed of the control motor 17 and the paint spraying flow rate of the liquid pump 11 (the control motor 17 can be a servo motor, a stepper motor, etc., and the liquid pump 11 can be a flow regulating pump) can be adjusted and set according to the requirements of the paint surface thickness and the paint spraying range during painting, so as to enhance the adaptability to different types of axles.

[0026] In addition, due to the effect of gravity, when the same paint flow rate is used, the paint thickness on the lower side of the axle will be lower than the paint thickness on the upper side of the axle. Therefore, in order to ensure the uniform thickness of the paint on the upper and lower sides of the axle, the upper and lower liquid guide shells 5 in the technical solution are respectively supplied by separate liquid pumps 11, and the discharge flow rate of the liquid pump 11 connected to the lower liquid guide shell 5 can be set to be slightly larger, so as to improve the uniformity of the paint thickness on the upper and lower sides of the axle.

[0027] like Figure 2 As shown, the circumferential paint spraying mechanism further includes a plurality of sealing caps 18; the sealing caps 18 correspond to the threads of the liquid outlet joints 8. In fact, in order to avoid excessive interference between the spraying ranges of different diffusion nozzles 9, the liquid outlet joints 8 may not be used in full, so the sealing caps 18 can be screwed onto the liquid outlet joints 8 that are not used, so as to seal these liquid outlet joints 8.

[0028] like Figure 2As shown, the side wall of the liquid guide shell 5 is fixed with an arc-shaped baking lamp 19. By setting the baking lamp 19 on the side wall of the liquid guide shell 5, the paint surface can be heated and baked in time while the paint is being sprayed, the drying speed of the paint surface can be increased, the problem of dust and debris in the air being easily adhered to the paint surface can be reduced, and the quality of the paint surface can be effectively improved.

[0029] like Figure 1 As shown, the front and rear sides of the upper end of the base 1 are respectively provided with slide grooves 20 in the left and right directions; the upper end of the base 1 is provided with an arched folding shield 21; the front and rear sides of the left end of the folding shield 21 slide correspondingly with the slide groove 20, and the front and rear sides of the right end of the folding shield 21 are respectively fixed to the base 1. During the painting process, the folding shield 21 can be slid along the slide groove 20 to stretch the folding shield 21 to shield and protect the outside of the axle, thereby reducing the problem of atomized paint flying in the air and improving the environmental protection effect.
