Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tire manufacturing and testing equipment, specifically a device for precise calibration of tire bead wire ring dimensions. Background Technology
[0002] The tire bead wire bead size precision calibration device is used to measure and calibrate key dimensions such as inner diameter, outer diameter, and roundness of tire bead wire bead during the production process.
[0003] Working principle:
[0004] When fixing the wire ring from the inside, if the initial end face of the wire ring is flat, then its end face will also be flat after fixing. If its initial end face is not flat, it will be offset under the action of friction during fixing. At this time, its end face will be at a certain angle to the horizontal plane, so as to measure whether the end face of the wire ring is flat in the initial state.
[0005] Existing precision calibration devices for tire bead wire dimensions have the following drawbacks: Most existing tire bead wire calibration devices use manual measurement and adjustment methods, while tire bead wires have significant elasticity, making it difficult to complete effective measurements while maintaining their normal shape, thus affecting the accuracy of the measurements.

[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. In this utility model, the steel wire ring to be tested is placed on the worktable. The operator lifts and rotates the sliding sleeve, which drives the first gear to rotate via the sliding rod, thereby driving the second gear and the rotating rod to rotate. This causes the fixing block to press the steel wire ring to be tested, moving it to the center of the worktable. At this time, the servo motor is driven to rotate the worktable. The flatness of the end face of the steel wire ring to be tested is measured by the first roundness meter. The servo motor is turned off, and the sliding sleeve is adjusted again to move the fixing block away from the steel wire ring to be tested. The steel wire ring to be tested returns to its normal shape under its own elasticity. The fixing seat is fixed to the steel wire ring to be tested by adjusting the lead screw and the cylinder. At this time, the third fixing rod is inserted into the through groove. The servo motor is driven to rotate the worktable, and the roundness and outer diameter of the steel wire ring to be tested are measured. Through the fixing component, the problem of the tire bead steel wire ring's own elasticity being unable to be effectively fixed during precise calibration of the tire bead steel wire ring size, thus affecting the measurement accuracy, is solved.
[0019] 2. In this utility model, the position of the first roundness meter is adjusted by the first connecting rod, the second connecting rod, and the third connecting rod, so that the pointer of the first roundness meter is parallel to and in contact with the upper surface of the steel wire ring to be tested. The first roundness meter is used to measure and detect whether the end face of the steel wire ring to be tested is flat. The first roundness meter is then retracted, and the pointer of the second roundness meter is adjusted by adjusting the scale rod to be in contact with the steel wire ring to be tested. The roundness and outer diameter of the steel wire ring to be tested are measured. Through the fixing component, the problem of the tire bead steel wire ring being unable to be effectively fixed due to its own elasticity, which affects the measurement accuracy, is solved when the tire bead steel wire ring size is accurately calibrated.

The screw 511 is inserted into the through hole 51. The scale rod 52 is adjusted and fixed by the screw 511, so that the pointer of the second roundness meter 59 is in contact with the outer side of the wire ring 6 to be tested.
[0033] Working principle:
[0034] During use, the operator places the steel wire ring 6 to be tested on the workbench 1, lifts and rotates the sliding sleeve 46, drives the sliding rod 45 and the first gear 41 to rotate, and then drives the three second gears 42 to rotate synchronously, so that the rotating rod 43 drives the fixed block 44 to move towards the center, clamps the steel wire ring 6 to be tested and moves it to the center position of the workbench 1. Then, the servo motor 7 is started to drive the workbench 1 to rotate, and the flatness of the end face of the steel wire ring 6 to be tested is measured by the first roundness meter 58.
[0035] After measurement, the sliding sleeve 46 is adjusted again to move the fixing block 44 away from the steel wire ring 6 to be measured. The steel wire ring 6 returns to its normal shape under its own elasticity. Next, by adjusting the lead screw 410 and the cylinder 412, the third fixing rod 414 is inserted into the through groove 415 and clamps the steel wire ring 6 to be measured. The servo motor 7 is started again to drive the worktable 1 and the fixed base 413 to rotate. The roundness and outer diameter of the steel wire ring 6 under normal conditions are measured by the second roundness meter 59 and the scale rod 52. The fixing component 4 solves the problem that the elasticity of the tire bead steel wire ring itself cannot be effectively fixed during the precise calibration of the tire bead steel wire ring size, which affects the measurement accuracy.
[0036] Through the hinged structure of the first link 55, the second link 56 and the third link 57, the position of the first roundness meter 58 can be flexibly adjusted so that the pointer of the first roundness meter 58 is parallel to and in contact with the upper surface of the steel wire ring 6 to be tested, and the flatness of the end face of the steel wire ring 6 is measured. By adjusting the scale rod 52, the pointer of the second roundness meter 59 is brought into contact with the outer side of the steel wire ring 6 to be tested, and the roundness and outer diameter of the steel wire ring 6 are measured. Through the detection component 5, the problem that the end face flatness, roundness and outer diameter cannot be measured at the same time when the tire bead steel wire ring size is accurately calibrated is solved, which affects the detection efficiency.
