Description

Technical Field

[0001] The present invention relates to the technical field of automobile tire assembly, and particularly relates to a tire lubricating oil spraying device for a tire automatic assembly line. Background Art

[0002] During the automobile manufacturing process, before the tire is assembled with the wheel hub, a layer of lubricating oil needs to be sprayed on the inner wall of the tire. In the prior art, a cylinder is mostly used to drive a lifting seat to lift and lower. A rotating mechanism is installed on the lifting seat, a bracket is installed on the rotating mechanism, and a spray head and an oil pipe are installed on the bracket. When the tire moves to a specified position, after the lifting seat descends, the rotating mechanism rotates, driving the bracket and the spray head to rotate, so as to complete the process of spraying lubricating oil on the inner wall of the tire. After the spraying is completed, the lifting seat rises to drive the spray head to disengage from the tire. The above prior art has the following problems: the rotating mechanism is installed on the lifting seat and rises and falls with the lifting seat, and the movement process is not flexible, and it will limit the efficiency of the spraying process. Summary of the Invention

[0003] The purpose of the present invention is to provide a tire lubricating oil spraying device for a tire automatic assembly line, which has the effects of flexible movement and high efficiency.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: a tire lubricating oil spraying device for a tire automatic assembly line, including a frame, the frame is rotatably connected with a plurality of conveying rollers arranged side by side, the frame is provided with a lifting and adjusting cylinder, the lifting and adjusting cylinder is arranged downward, the piston rod of the lifting and adjusting cylinder is rotatably connected with a bracket, the lower end of the bracket is provided with an oil pipe and a spray head, a pump is installed on the oil pipe, the frame is provided with an oil tank, and the oil pipe is connected with the oil tank; the frame is provided with a rotatable turntable and a rotary cylinder for driving the turntable to rotate, the turntable is provided with a through hole, and the bracket passes downward through the through hole.

[0005] By adopting the above technical solutions, the tire is placed on the conveying rollers and stops after reaching the specified position. The lifting and adjusting cylinder drives the bracket to descend until the spray head at the lower end of the bracket is located inside the tire. The rotary cylinder drives the turntable to rotate, the turntable drives the bracket to rotate, and the spray head on the bracket rotates with the bracket, so as to spray lubricating oil inside the tire.

[0006] The further setting of the present invention is: a first synchronous pulley is installed on the turntable, a second synchronous pulley is installed on the piston rod of the rotary cylinder, and a first synchronous belt is installed between the first synchronous pulley and the second synchronous pulley.

[0007] By adopting the above technical solutions, the rotary cylinder drives the turntable to rotate through the first synchronous belt.

[0008] A further setting of the present invention is that conveying devices are provided on both sides of the frame. The conveying devices include a rotatable rotating shaft 1, a rotating shaft 2, and a motor for driving the rotation of the rotating shaft 1. A synchronous pulley 3 is installed on the rotating shaft 1, a synchronous pulley 4 is installed on the rotating shaft 2, and a synchronous belt 2 is installed between the synchronous pulley 3 and the synchronous pulley 4; the frame is fixed with a mounting bracket 1 and a mounting bracket 2. The mounting bracket 1 is rotatably connected to a transmission column 1. A synchronous pulley 5 is installed on the rotating shaft 1, a synchronous pulley 6 is installed on the transmission column 1, and a synchronous belt 3 is installed between the synchronous pulley 5 and the synchronous pulley 6. A synchronous pulley 7 is installed on the rotating shaft 2, a synchronous pulley 8 is installed on the transmission column 2, and a synchronous belt 4 is installed between the synchronous pulley 7 and the synchronous pulley 8.

[0009] By adopting the above technical solution, in the prior art, the conveying method of tires is mostly to drive the conveying roller to rotate by a motor, and the tires are conveyed by the rotating conveying roller. During the actual use of the present invention, a conveyor belt is also provided below the conveying wheel for conveying the wheel hub. Therefore, if a motor is installed on the side or below of the conveying roller, it will occupy space. Therefore, the present invention does not adopt the method of driving the conveying roller to rotate by a motor, but drives the rotating shaft 1 by a motor, the rotating shaft 1 drives the rotating shaft 2 to rotate, and then drives the transmission column 1 and the transmission column 2 to rotate. When the tire is located between the two transmission columns 2, the two transmission columns 2 are attached to the side wall of the tire and lift the tire above the bracket and then stop. After the lubricating oil is sprayed, the two transmission columns 1 and the two transmission columns 2 rotate to continue conveying the tire forward. The motor can be installed on the top of the frame without occupying the side space.

[0010] A further setting of the present invention is that the frame is provided with side plates on both sides of the conveying roller and a top plate above the conveying roller, and a spraying chamber is formed between the side plates and the top plate.

[0011] By adopting the above technical solution, by forming a spraying chamber, the sprayed lubricating oil is prevented from splashing everywhere.

[0012] The beneficial effect of the present invention is that the present invention installs a spray head on the bracket, the lifting adjustment air cylinder adjusts the lifting of the bracket, and the rotary cylinder adjusts the rotation of the bracket, achieving the effects of flexible lifting and rotation actions of the bracket and improving the spraying efficiency.
