Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rim apparatus for testing uniformity of a tire in which a tire is mounted on a rim of a uniformity apparatus during uniformity testing of the finished tire, To a rim device for testing uniformity of a tire which can be smoothly mounted and separated in a rim without performing lubricant application of release agent to the bead portion.
Typically, a tire that has undergone a vulcanization process during the manufacture of a tire is completed through an expansion process, a trimming process, and a repair process, and the finished tire is finally subjected to an inspection process before being put into a warehouse.
The uniformity test, which is one of the inspection processes of the finished tire, measures whether or not the semi-finished products of the tire used for manufacturing the tire are made uniformly positioned.
Conventionally, the uniformity equipment used in the tire uniformity test measurement is designed to measure the force variation in the longitudinal direction and the lateral direction of the tire while mounting the tire on the upper and lower rims and rotating the tire while the tire is being inflated.
When the tire is mounted on the upper and lower rims of the uniformity facility in the conventional uniformity test of the finished tire, the lubricant of the releasing agent is first applied to the tire bead portion using the application roller, and then the tire bead portion, So that the smooth tires can be engaged and separated.
However, there is a problem in that a measurement error may occur in the tire uniformity test because deviation in measurement data may occur due to unevenness of application amount of the release agent lubricant applied to the tire bead portion and lubricant application time.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems occurring in the prior art, and it is an object of the present invention to provide an apparatus and a method for mounting a tire on upper and lower rims of a uniformity apparatus, And the tire bead portion is smoothly mounted on or separated from the upper and lower rims using pneumatic pressure.
In order to accomplish the above object, the present invention provides a tire uniformity inspection rim apparatus in which a tire bead is seated on a seating contact surface of upper and lower rims provided in a uniformity facility to perform a uniformity inspection of a finished tire, And the segment module is provided with a slider which moves forward and backward along a linear guide, and which is provided with a linkage for contracting / expanding the linkage to the bead inner wear segment And are installed on the upper and lower rim bodies, respectively.
Further, in the present invention, the body of the upper and lower rims is provided with a pneumatic passage for supplying or exhausting pneumatic pressure to the inside of the mounted tire.
The rim device for testing the uniformity of tires according to the present invention is characterized in that when the tires are mounted on the upper and lower rims of the uniformity facility for the inspection of the uniformity of the finished tire, the tires are smoothly and accurately applied to the upper and lower rims It is possible to perform the uniformity inspection measurement, thereby improving the reliability of the measurement data by measuring the uniformity.
