Automatic scanning, measuring and analyzing device and method for engineering tire winding tread shape

Abstract

The invention discloses an automatic scanning, measuring and analyzing device for an engineering tire winding tread shape. The automatic scanning, measuring and analyzing device for the engineering tire winding tread shape comprises a winding machine, and the winding machine comprises an X-axis moving track arranged in the X-axis direction, a Y-axis moving track arranged in the Y-axis direction and a Z-axis moving track arranged in the Z-axis direction. A using method of the device comprises the steps that an outline curve and coordinates of a tire blank are acquired; an outline curve and coordinates of a tread are acquired; and the outline curve of the tire blank and the outline curve of the tread are integrated together, denoising is conducted, and the distance between the tire blank andthe tread is calculated and taken as the thickness of the tread section. According to the automatic scanning, measuring and analyzing device for the engineering tire winding tread shape, the size ofthe engineering tread with any size is analyzed; scanning is automatically conducted along with the tread outline, azimuth coordinate information is synchronously collected, the measuring process is convenient to operate, and use is easy; the measuring precision is high, and a precise electronic ruler can detect and feed back the position of each degree of freedom; mechanical errors can be greatlyreduced through the feedback position of the electronic ruler; and measuring errors brought by manual operation are eliminated, the measuring precision and efficiency are improved, the tread can notbe damaged, and the detection cost is reduced.

Description

technical field [0001] The invention relates to a device and a method, in particular to an automatic scanning measurement and analysis device and method for the shape of an engineering tire winding tread. Background technique [0002] In the engineering tire winding process, the tire embryo starts to rotate under the drive of the rotary machine, and the rubber strip is wound on the tire embryo to form a tread. For a certain type of tire, the shape of the tread has specified requirements, so according to the preset program, the number of turns of winding is different at different positions to form a tread of the specified shape. Since the thickness of the rubber strip changes from time to time, it is wound according to the predetermined number of turns. Generally speaking, the shape of the tread cannot fully meet the specified requirements, but as long as it is within the error range. So how do you know whether the shape of the tread has reached the specified error range? ...

Problems solved by technology

There are problems with this measurement method: the sample is deformed, causing errors: after the tread is cut, it deforms and expands, which is not exactly the same as before it was not cut; because the tread is a soft material, it will cause human error when measured with a caliper; Different angles and strengths will cause errors; damage samples, waste production time, and reduce production efficiency; the measurement process is cumbersome, time-consuming, and low-efficiency
