Description

TECHNICAL FIELD

[0001] The utility model relates to tire roundness measuring device technical field especially relates to a kind of roundness detection equipment applied in tire mold pie round process. BACKGROUND

[0002] In the tire manufacturing process, the roundness of tire mold is one of the key factors to ensure tire quality. Especially in the tire pie round process, the roundness of mold directly affects the uniformity and driving stability of tire. Roundness runout, as an important indicator to measure the roundness of tire mold, reflects the change of the distance from each point on the surface of the mold to the center when the mold rotates. Good roundness runout control is essential to reduce the vibration and noise of tire during rolling and improve the durability of tire. The traditional roundness detection device usually adopts fixed structure, and this structure is not enough when dealing with tire molds with large differences in size and shape in pie round process. Due to the limited range of movement of the detector, it is difficult to adapt to the detection needs of tire molds of different sizes and shapes. In addition, due to structural limitations and wear during long-term use, the positioning accuracy of traditional equipment often decreases, affecting the accuracy of detection results.

However, this structure has obvious defects. Since the three transmission arms are directly connected, the three transmission arms will move relative to each other during transmission. Long-term use of this structure is prone to wear and looseness, which affects the positioning accuracy of the sensor and the accuracy of the detection results. UTILITY MODEL CONTENTS

[0060] On the horizontal guide rail 730, a Y-axis transmission member 740 is arranged. The Y-axis transmission member 740 is connected to the horizontal guide rail 730 through a sliding connector and can slide on the horizontal guide rail 730. The design of the Y-axis transmission member 740 takes into account the rigidity and stability, ensuring that it can bear the weight of the detection device 300 and maintain stable transmission.

[0061] The Y-axis actuator 500 is arranged at the end of the Y-axis transmission member 740 in the Y-axis direction, and can drive the detection device 300 to move in the Y-axis direction by driving the Y-axis transmission member 740 to slide on the horizontal guide rail 730. The Y-axis actuator 500 also adopts a high-performance servo motor and a precise transmission mechanism, and has the characteristics of fast response speed and high positioning accuracy. The installation position and design of the Y-axis actuator 500 take into account the overall structure and transmission efficiency of the device, ensuring that it can fully play its driving role.

The rotating disc portion 220 is relatively rotated with the mounting portion 210 through a rotating brake 230. The rotating brake 230 can accurately control the rotating speed and rotating angle of the rotating disc portion 220 to meet the detection needs of different tire molds. At the top end of the rotating disc portion 220, a plurality of positioning grooves 221 are also provided, which are used to fix and position the tire mold after the circle splicing process is performed, ensuring that the tire mold does not deviate or shake during the detection process, thereby improving the detection accuracy. In this embodiment, the rotating brake 230 can be, for example, a motor, a reducer, etc., which will not be described in detail here.
