Description

TECHNICAL FIELD

[0001] The utility model belongs to the marking technical field, especially relates to a marking device of tire dynamic balance testing machine. BACKGROUND

[0002] The dynamic balance of tire refers to the different degree of centrifugal force in each direction when the tire rotates, and is an important parameter for evaluating the quality of tire.When the dynamic balance of tire is good, the force in each direction during the rotation of tire is basically the same, and when the dynamic balance of tire is not good, the centrifugal force in a certain direction is too large or too small, thereby affecting the quality of tire, and seriously, the tire is extremely easy to cause tire burst during operation after being installed on the automobile, causing safety accidents. Therefore, the general tire needs to be tested by dynamic balance before leaving factory or after being repaired, so as to ensure the quality of tire and eliminate the safety hazard.

[0003] The dynamic balance machine is a machine for measuring the size and position of the unbalance of rotating object (rotor), and the test of dynamic balance is completed by the dynamic balance machine. When any rotor rotates around the axis, the centrifugal force is generated due to the uneven mass distribution relative to the axis. The unbalanced centrifugal force acting on the rotor bearing will cause vibration, generate noise and accelerate the wear of bearing, so as to seriously affect the performance and life of product.

[0004] The side of tire is provided with visual indication composed of red solid dot and yellow hollow dot. The red dot symbolizes the position with the strongest longitudinal rigidity of tire, and when the tire rotates, the largest vibration is generated here, which is the key mark of performance. The red dot represents the taper direction, and reflects the inclination direction of tire after being inflated, so when the tire is assembled, the red dots of the tires on both sides must be simultaneously outward or simultaneously inward, and the tire with large taper is easy to make the automobile deviate. The yellow hollow dot, i.e. light point mark, marks the lightest part on the circumference of tire. When the tire is replaced, it is crucial that the light point must be aligned with the air valve on the heaviest position of rim to ensure the balance of assembled wheel.

[0005] At present, when the red solid dot and the yellow hollow dot are marked, manual marking is usually adopted, and this way needs manual operation, which is time-consuming and laborious, and the manual operation error is large, and error is easy to occur, thereby affecting the dynamic balance of tire.

A delivery tube 23 connects the pigment supply bottle and the color block 22.

[0035] The specific implementation process is as follows:

[0036] Assume that the red solid dots are marked first, and then the yellow hollow dots are marked. Place the tire 2 on the test station of the dynamic balancing tester 1. The dynamic balancing tester 1 performs a dynamic balance test and displays the test results on the computer screen. The dynamic balancing tester 1 first detects the position of the maximum vibration. After detection, the computer rotates this position to the top of the marking component. Then, the foot valve 5 of the first marking structure is stepped on, so that the lifting cylinder 11 and the marking head 15 of the first marking structure are connected to the air pump. When the marking head 15 adopts the first structure, the air pump injects gas into the lifting cylinder 11 and the outer tube 18. The lifting cylinder 11 drives the marking head 15 to rise as a whole. At the same time, the gas entering the outer tube 18 drives the marking tube 19 to rise. When the marking tube 19 rises to the maximum height, the gas entering the marking tube 19 pushes the piston 20 upward. The piston 20 pushes the internal pigment to spray out from the circular opening or annular opening at the top of the marking tube 19, thereby achieving marking. The controller controls the air pump to switch the direction of the gas flow. The air pump draws out the gas from the lifting cylinder 11 and outer tube 18, causing the lifting cylinder 11 to lower the marking head 15 as a whole. The marking tube 19 inside the outer tube 18 also descends. When the marking tube 19 reaches its limit, the piston 20 also moves downward, allowing the pigment in the pigment storage bucket to be added to the marking tube 19. When the marking head 15 adopts the second configuration, the air pump injects gas into the lifting cylinder 11 and outer tube 18. The lifting cylinder 11 drives the marking head 15 to rise as a whole. Simultaneously, the gas entering the outer tube 18 drives the marking rod 21 to rise, which in turn drives the color block 22 to rise, thereby achieving marking. The controller controls the air pump to switch the direction of the gas flow. The air pump draws out the gas from the lifting cylinder 11 and outer tube 18. The lifting cylinder 11 drives the marking head 15 to lower as a whole. The marking rod 21 inside the outer tube 18 also descends, which in turn drives the color block 22 to return to its original position.

[0037] After marking is complete, release the foot valve 5 of the first marking mechanism, disconnecting the air pump from the lifting cylinder 11 and the outer tube 18. The dynamic balancing tester 1 rotates again to detect the lightest part of the tire 2's circumference. Once detected, repeat the above steps (while still pressing the foot valve 5 of the second marking mechanism). Once all markings are complete, manually remove the tire 2 and transport it to the next station.
