Description

Technical Field

[0001] This utility model relates to the field of tire processing technology, specifically to a testing device for tire forming drums. Background Technology

[0002] The tire forming drum inspection device is a key piece of equipment to ensure tire production quality. It is usually a multi-functional device that includes mechanical measuring components to accurately measure the physical parameters of the forming drum, such as size and roundness, to ensure that its accuracy and performance meet production requirements and guarantee tire forming quality.

[0003] Existing testing equipment can only perform simple visual inspections on the surface of tire forming drums, such as observing whether there are obvious scratches or bumps. It lacks effective means to detect internal structural defects and the quality of internal welds. This means that some forming drums with internal hidden dangers may experience problems such as air leakage and drum deformation after being put into use, affecting the tire forming quality and production efficiency.

[0011] Preferably, the inner side of the clamp is provided with protective rubber, which plays the main protective role.

[0012] Preferably, the laser displacement sensor covers the entire top of the base, facilitating the detection of the tire forming drum located on the top of the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This inspection device for tire forming drums uses a laser displacement sensor covering the top of the base to perform comprehensive dimensional accuracy inspection of the tire forming drum, such as measuring key dimensions like the drum's diameter and profile. This provides accurate data for determining whether the drum's dimensions meet standards. The ultrasonic sensor can extend into the tire forming drum via a lifting rod to inspect its internal structure, such as air cavities, effectively detecting potential internal defects like voids and cracks. This achieves multi-dimensional precision inspection from the surface to the interior.

[0015] 2. This testing device for tire forming drums features a motor in the support unit that drives a turntable to rotate the tire forming drum on the tray at a uniform speed. Combined with a limiting unit that securely limits the forming drum, the testing process can be carried out continuously and stably, eliminating the need for frequent manual adjustments to the drum's position and improving testing efficiency. Furthermore, the inner side of the clamping plate of the limiting unit is equipped with protective rubber, which prevents damage to the drum's surface during the limiting and fixing process, ensuring the integrity of the forming drum during testing and thus guaranteeing the stability of the test results.

[0022] Please see Figure 1-4 The present invention provides the following technical solution: a detection device for tire forming drum, comprising a support mechanism 1 and a monitoring mechanism 2, wherein the monitoring mechanism 2 is movably connected to the surface of the support mechanism 1.

[0023] The monitoring mechanism 2 includes a support unit and a limiting unit. The support unit is rotatably connected to the top of the bearing mechanism 1, and the limiting unit is disposed on the surface of the support unit.

[0024] The supporting mechanism 1 consists of a base 101, a support column 102, a crossbeam arm 103, a signal transmission module 104, a connecting frame 105, and a laser displacement sensor 106. The support column 102 is fixedly connected to the top of the base 101, the crossbeam arm 103 is fixedly connected to the top of the support column 102, the signal transmission module 104 is fixedly connected to the top of the crossbeam arm 103, the connecting frame 105 is fixedly connected to the bottom of the crossbeam arm 103, and the laser displacement sensor 106 is fixedly connected to the surface of the connecting frame 105. The laser displacement sensor 106 covers the entire top of the base 101, facilitating the detection of the tire forming drum located on the top of the base 101 through the laser displacement sensor 106, and playing a major supporting role.

[0025] The support unit consists of a turntable 201, an output shaft 202, a motor 203, a bracket 204, a tray 205, and a through hole 206. The turntable 201 is rotatably connected to the top of the base 101. The output shaft 202 is fixedly connected between the turntable 201 and the motor 203. The motor 203 is fixedly connected to the inner top of the base 101. The bracket 204 is fixedly connected to the top of the turntable 201. The tray 205 is fixedly connected to the top of the bracket 204. The through hole 206 is formed on the surface of the tray 205, mainly serving to support the tire forming drum and drive its rotation. The limiting unit consists of a lifting seat 211, a lifting rod 212, an ultrasonic sensor 213, a telescopic frame 214, a clamping plate 215, and a polarizing lamp 216. The system consists of a lifting base 211 fixedly connected to the top of the turntable 201, a lifting rod 212 movably connected to the top of the lifting base 211, and the lifting rod 212 and ultrasonic sensor 213 located within the through hole 206 for easy movement, allowing the ultrasonic sensor 213 to extend into the interior of the tire forming drum for detection via the lifting rod 212.
