Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a locomotive bogie spraying automation equipment. Background Art

[0002] A vehicle bogie refers to an independent running structure composed of two or more pairs of wheels on a vehicle connected into a group by a frame and other devices, which can rotate relative to the vehicle body and is equipped with springs and other components. Depending on the gross weight of the vehicle, the vehicle body is supported on two or more bogies. The running gear of a general vehicle is mostly composed of two two-axle bogies, and a few vehicles use three-axle bogies, and a few long and large freight vehicles are composed of four, six or eight bogies. The more axles there are, the greater the load capacity of the vehicle. The bogie is usually composed of a side frame (or frame), wheels, axle boxes, spring damping devices, bolsters, bogie basic brake devices, etc. According to the purpose, it can be divided into two categories: passenger car bogies and freight car bogies.

[0003] At present, the spraying of locomotive bogies is mainly completed by full manual operation. A group of three or four people use manual paint spray guns to spray the upper and lower, left and right, front and back, inside and outside of the locomotive bogies in an environment filled with paint mist, which takes about 3 hours. The main problem of this traditional and backward manual spraying operation method is that the highly dispersed paint mist and volatile solvents not only pollute the environment and are not good for human health, but also waste paint and cause economic losses. Manual spraying has a low degree of automation, is time-consuming and labor-intensive, and the quality of spraying depends entirely on the operation of the workers. It can no longer meet the needs of the intelligentization of Industry 4.0 and the increasingly high quality requirements of spraying processes. Utility Model Content

[0004] In view of the shortcomings of the prior art that locomotive bogie spraying is mainly completed by full manual operation, such as poor working environment, backward means and poor spraying effect, the utility model provides a locomotive bogie spraying automation equipment, which has the advantages of improving the work efficiency of workpiece spraying paint, realizing standardized operation, less-managed management, ensuring the consistency of spraying effect and reducing operating costs.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a locomotive bogie spraying automation equipment, including a spraying room body and a monitoring mechanism, a spraying room is arranged inside the spraying room body, a lifting rail supporting steel structure is fixedly connected to the top of the spraying room, an electric hoist lifting trolley is installed outside the lifting rail supporting steel structure, a control mechanism is arranged inside the spraying room, a paint conveying and mixing mechanism is arranged inside the spraying room, a workpiece hanger is arranged outside the lifting rail supporting steel structure, and the bottom of the spraying room body is fixedly connected to the foundation.

[0006] Preferably, a robot external axis is provided inside the spray booth, a robot is provided outside the robot external axis, a spraying mechanism is installed outside the robot, and a workpiece to be sprayed is connected to the tail end of the workpiece hanger.

[0007] Preferably, the paint conveying and mixing mechanism includes a pneumatic lifting and stirring mechanism, a high-pressure pneumatic pump, a pressure-stabilizing valve, a paint filter and a paint bucket, which are used to convey and mix paint for spraying.

[0008] Preferably, the spraying mechanism includes a mixed air spray gun, a spray gun anti-collision mechanism and an explosion-proof solenoid valve, which are used for spraying paint on the outside of the workpiece. The spray gun anti-collision mechanism includes a gun rack, a safety pin and a wear-resistant ring, which are used to protect the spray gun.

[0009] Preferably, the control mechanism includes an equipment control cabinet and a robot-specific control cabinet, the control cabinet is equipped with a leakage protection device, and the control mechanism is provided with grounding, phase sequence, short circuit, phase loss and overload protection.

[0010] Preferably, the monitoring mechanism includes a camera and a display screen to facilitate operators to view the spraying operation of the workpiece. The monitoring mechanism has a video recording function to record the spraying process and provide a basis for repairing and determining the cause of equipment failure.

[0011] Preferably, the robot body is arranged on a slide plate provided on the external axis of the robot, and the robot and the spraying mechanism dynamically move back and forth along the slide plate on the external axis of the robot according to the requirements of the spraying process.

[0012] Beneficial effects:

[0013] 1. The locomotive bogie spraying automation equipment uses a transport vehicle to transport the bogie to the predetermined position of the first spray painting room. After the electric hoist trolley is translated into position on the lifting track support steel structure, the workpiece hoist is lowered to lift the bogie. The electric hoist rises to a suitable height, the robot is started, and the spraying mechanism is driven to move horizontally and dynamically along the external axis forward and backward. The right half of the painting bogie is automatically completed according to the contour trajectory. Then, the electric hoist trolley lifts the bogie and translates it to the right on the lifting track support steel structure to the predetermined position of the second spray painting room, and repeats the above steps to complete the left half of the painting bogie, that is, the automated spraying of the bogie is completed.

[0014] 2. The locomotive bogie spraying automation equipment uses a fully hollow wrist to embed the paint tube and air tube into the arm, without any pipes exposed on the outside. All axes contain programmable software limits to limit the robot's operation overtravel. The axis can be driven to a hard stop where the overtravel operation may cause damage to the robot. All axis systems are equipped with braking systems. In the event of an emergency stop, error or power failure, the movement of the arm in full load, full extension and full speed can be stopped in a short time. When the power is removed, all brake systems are in the "ON" (use) state by default, and the brake of the corresponding axis can be manually released through the brake release button on the control cabinet. The device has high safety. BRIEF DESCRIPTION OF THE DRAWINGS
