Description

Technical Field

[0001] The utility model relates to the technical field of tire identification, in particular to a tire hardness identification device. Background Art

[0002] Automobile tires are one of the most important parts of a car. They are in direct contact with the road surface and work together with the car suspension to mitigate the impact of the car when driving, ensuring that the car has good ride comfort and driving smoothness. The hardness (rubber hardness) of tires of different specifications and types (such as snow tires, off-road tires, road tires, etc.) has different effects on tire performance such as grip, driving noise, and comfort. When inspecting and identifying tire quality, one of the items is hardness test. Currently, tires are generally inspected using cone-shaped tools or other sharp tools. The tires are poked by the tools, so the force of each poking is inconsistent, resulting in inaccurate detection.

[0003] The Chinese utility model patent document with the announcement number CN219512024U provides a motor vehicle tire hardness detection device. The beneficial effects of this utility model are as follows: 1. The utility model drives a cross-plate with nails to reciprocate up and down by rotating the tire. When the cross-plate with nails moves upward, the tire is detected with uniform force, achieving the effect of fast and automatic detection; 2. The utility model drives the tire to cooperate with the rotating ring through the output shaft of the support frame, and the output shaft of the motor drives the tire to rotate, thereby realizing tire detection, achieving the effect of human control and simple operation.

[0004] The disadvantage of this solution is that it drives the cross plate with nails to move up and down by rotating the tire. First, during each rotation of the tire, the triangular cone nails pierce the same position on the tire each time, which does not meet the identification requirement of measuring different positions multiple times to obtain the average value; second, during the process of the triangular cone nails piercing the tire, the tire is still rotating, which will tear and damage the tire.

[0011] Furthermore, the lateral movement mechanism includes a rotating seat connected to the movable seat, and a rotating pin and two positioning holes are provided on the rotating seat.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-7The utility model provides a tire hardness identification device, including a vertical plate 1, a rotating ring 2 for fitting a tire 5 is rotatably provided in front of the vertical plate 1, a longitudinal moving mechanism 19 is provided on one side of the rotating ring 2, a transverse moving mechanism 20 is provided on the longitudinal moving mechanism 19, and a Shore hardness tester 13 is provided on one end of the transverse moving mechanism 20 close to the rotating ring 2.

[0027] In this application, the Shore A durometer 13 can be selected as a Shore A durometer with a measuring range of 0-100HA. After adjusting the Shore A durometer 13 through the lateral moving mechanism 20 and the longitudinal moving mechanism 19, the hardness value of the rubber on the tire is measured. After rotating the tire, the hardness value at different positions on the tire can be measured. The operation is simple and convenient, and the tire will not be damaged during the entire process.

[0028] The longitudinal moving mechanism 19 includes a longitudinal slide 4, a longitudinal screw rod 9, and a longitudinal guide rod 10. The longitudinal screw rod 9 and the longitudinal guide rod 10 both pass through the longitudinal slide 4. The longitudinal screw rod 9 is slidingly connected to the longitudinal slide 4. The rear end of the longitudinal screw rod 9 is fixedly connected to the vertical plate 1. The longitudinal guide rod 10 is threadedly connected to the longitudinal slide 4. The rear end of the longitudinal guide rod 10 is rotatably connected to the vertical plate 1. A transverse moving mechanism is provided on the longitudinal slide 4.

[0029] When the longitudinal screw rod 9 is rotated, the longitudinal slide 4 is driven to move longitudinally along the longitudinal guide rod 10 , driving the transverse movement mechanism 20 and the Shore hardness tester 13 to move, so as to adjust the longitudinal position of the Shore hardness tester 13 .

[0030] The transverse movement mechanism includes a transverse screw rod 6, a transverse guide rod 7, a transverse slide 8, and a movable seat 18. The transverse screw rod 6 and the transverse guide rod 7 both pass through the transverse slide 8. The transverse screw rod 6 and the transverse slide 8 are threadedly connected, the transverse screw rod 6 and the movable seat 18 are fixedly connected, the transverse guide rod 7 and the transverse slide 8 are slidingly connected, the transverse guide rod 7 and the movable seat 18 are fixedly connected, the bottom of the transverse slide 8 is connected to the top of the longitudinal slide 4, and a Shore hardness tester 13 is set at the end of the movable seat 18 away from the transverse slide 8.

[0031] When the transverse screw rod 6 is rotated, the movable seat 18 is driven, and the movable seat 18 is in sliding contact with the longitudinal slide 4 through the transverse guide rod 7, and moves in a transverse linear manner, driving the Shore hardness tester 13 to adjust its transverse position.

[0032] A pressure sensor 12 is provided between the Shore hardness tester 13 and the lateral movement mechanism. The Shore hardness tester 13 and the pressure sensor 12 are fixedly connected, and the pressure sensor 12 is rotatably connected to the lateral movement mechanism.

[0033] The pressure sensor 12 is connected to an external controller, which receives and displays the data from the pressure sensor 12. The Shore hardness tester 13 is installed on the working end of the pressure sensor 12. When the probe of the Shore hardness tester 13 is pressed on the tire, the pressure is synchronously transmitted to the pressure sensor 12, making it easier to observe and measure the pressure values at different positions, further improving the accuracy of the measurement.

[0034] The lateral movement mechanism includes a rotating base 11 connected to a movable base 18, and a rotating pin 16 and two positioning holes 17 are provided on the rotating base 11. The end of the pressure sensor 12 close to the movable base 18 is mounted on the rotating base 11 by rotating in the horizontal direction through the rotating pin 16. The two positioning holes 17 form a right angle with the rotating pin 16. A movable pin 15 is movably provided in the positioning hole 17. The movable pin 15 passes through the pressure sensor 12 and extends from the top of the positioning hole 17, so that the pressure sensor 12 can be rotated 90 degrees around the rotating pin 16 to the side close to the tire 5.

[0035] When measuring the hardness value on the tire circumference, adjust the Shore hardness tester 13 to rotate to the position as shown in the figure. Figure 4 As shown, the probe of the Shore durometer 13 is oriented parallel to the radial direction of the tire. When in use, the position of the Shore durometer 13 is adjusted so that the probe is pressed vertically against the circumferential surface of the tire. When measuring the sidewall of the tire, the Shore durometer 13 is adjusted to rotate to a direction perpendicular to the sidewall of the tire. At this time, the probe of the Shore durometer 13 is oriented parallel to the axial direction of the tire. When in use, the probe of the Shore durometer 13 is against the sidewall of the tire.

[0036] A longitudinal handle 3 is provided at the front end of the longitudinal screw rod 9 , and a transverse handle 14 is provided at the end of the transverse screw rod 6 away from the movable seat 18 .

[0037] The longitudinal screw rod 9 is rotated by the longitudinal handle 3 and the transverse screw rod 6 is rotated by the transverse handle 14, thereby improving the convenience of operation.

[0038] Working principle: When in use, put the tire 5 on the rotating ring 2, turn the longitudinal handle 3 to adjust the longitudinal position of the Shore durometer 13, so that the Shore durometer 13 moves to the range corresponding to the tire circumferential surface, then turn the transverse handle 14 to adjust the transverse position of the Shore durometer 13 so that the probe of the Shore durometer 13 is against the tire circumferential surface, continue to turn the transverse handle 14 to press the probe of the Shore durometer 13 into the tire circumferential surface, observe whether the pressure value displayed by the pressure sensor 12 is within the required range, then observe the value of the Shore durometer 13, then rotate the tire, measure the hardness at different positions on the circumferential surface multiple times, calculate the average value, and identify the quality of the tire;

[0039] When testing the hardness of the tire sidewall, remove the movable pin 15, turn the pressure sensor 12 and the Shore hardness tester 13 toward the tire sidewall, and insert the movable pin 15 into the tire sidewall. Figure 4 The pressure sensor 12 and the Shore durometer 13 are clamped in the other positioning hole 17 shown, and then the horizontal handle 14 and the longitudinal handle 3 are rotated to adjust the probe of the Shore durometer 13 to the side wall of the tire. Finally, the longitudinal handle 3 is continued to be rotated to observe the value of the pressure sensor 12. After the pressure reaches the standard, the value of the Shore durometer 13 is read; the tire 5 is rotated, and the hardness values at different positions on the tire sidewall are measured multiple times, and the average value is calculated to identify the tire quality.
