Problems solved by technology

Because the surface of the tire crown belongs to a hyperboloid structure, this greatly increases the difficulty of drawing lines on the tire crown, so the pure manual method of drawing lines is not only extremely inefficient, but also has a large error, which is not conducive to the next step of the tire. processing
On the other hand, there have been people who have used a pen fixed at one point to gradually approach the surface of the rotating tire to draw tire circumferential lines. The normal plane of the main axis is not parallel everywhere, but the edge of the tire will swing left and right during the rotation process, so the circumferential lines drawn by this method are not parallel to the edge of the tire, and the ideal drawing effect cannot be achieved

Abstract

The tire tread set work device features in the fixed support device connects separately with floating positioning device, micro adjusting device, staff gage and set work device. With this device, the drawing speed on the tire tread is several times or even ten times faster than hand drawing, with improved efficiency and precision. Besides, the horizontal section line is even more convenient with higher parallel degree, with the assistance of the vertical staff gage, figured spacing section being easier and ensured of the fine precision. This is simple, and low in cost.

Description

Technical field: [0001] The invention relates to mechanical equipment for producing tires, in particular to a device capable of quickly drawing vertical and horizontal lines on the tire surface. Background technique: [0002] In the current existing technologies, most of them rely on pure manual methods to draw various lines on the surface of smooth tires, and the efficiency and precision are low. When developing new products of automobile tires or retreading tires, it is often necessary to draw important lines such as centerlines, pattern contour lines, and pattern pitch segment lines on the surface of smooth tires (tires without patterns on the surface); currently existing In the technology, most of them rely on pure manual methods to draw the above-mentioned lines according to the design size with tools such as white pencils and steel tapes or sample strips. Because the surface of the tire crown belongs to a hyperboloid structure, this greatly increases the difficulty of...
