Description

Technical Field

[0001] The utility model relates to the technical field of tire processing equipment, and more specifically to a double-station tire section profile scanning test machine. Background Art

[0002] As an important load-bearing component in vehicles such as automobiles and airplanes, tires are of great significance for the study of tread patterns, tire profiles and structures. There are also strict restrictions on the detection standards for tire defects, profiles, sizes and other parameters. The relevant tire manufacturing companies have an increasing demand for non-destructive testing equipment for tires. By scanning and testing the tire surface profile, measuring the tire's curves, patterns, wear, defects and other surface conditions, the most accurate measurement data of the tire can be obtained to improve the research and development cycle and detection efficiency of tire manufacturing.

[0003] Based on the above, the inventors found that most of the existing tire scanning test machines on the market are made by placing the tire on a frame, driving the tire to rotate at a certain speed with a motor, and providing a laser displacement sensor to detect the tire contour. However, during the detection process, the position of the laser displacement sensor is mostly fixed, which is not convenient to adjust according to the size of the tire, resulting in inaccurate data scanned by the tire, reducing its applicability. At the same time, the existing tire scanning test machine can only scan and detect one tire at a time during detection, and the detection time is relatively long, which in turn affects its working efficiency. Therefore, in view of this, the existing structure is studied and improved, and a double-station tire section contour scanning test machine is provided, in order to achieve a more practical purpose.

[0043] Example:

[0044] See also Figure 1-5 The double-station tire cross-section profile scanning test machine comprises a frame 1 and a support frame 2 located on one side of the frame 1. Two symmetrically arranged X-axis linear modules 3 are installed on the frame 1. A Y-axis linear module 4 is fixedly installed on the slide of the X-axis linear module 3. A support seat 5 is fixedly connected to the top of the slide of the Y-axis linear module 4. Three support shafts 6 are fixedly connected to the top of the support seat 5. A laser displacement sensor 7 is arranged on the periphery of the support shaft 6. Two symmetrically arranged mounting seats 8 are fixedly connected to the top of the support frame 2. A dual-axis motor 9 is installed between the two mounting seats 8. The output shafts at both ends of the dual-axis motor 9 are connected to the tire shaft 11 through a coupling 10. The two tire shafts 1 The ends of the three laser displacement sensors 7 that are far from each other are each provided with a fixing mechanism 12. When in use, the three laser displacement sensors 7 are arranged at a certain angle and a laser triangulation method is adopted, that is, a laser beam is emitted from the laser displacement sensor 7 at a certain angle to the tire surface, and a series of reflections will appear on the tire surface, among which a beam of light will be reflected back to the laser displacement sensor 7 from another angle to form a light spot. The distance between the measured tire surface and the laser emission point is different, and the angle of the reflected light received by the sensor is also different. The distance between the laser displacement sensor 7 and the measured tire is calculated according to the angle of the reflected light, wherein the emitted light can completely cover the tread and the sidewalls of the tire.

[0045] See also Figure 5 Both ends of the laser displacement sensor 7 and one side close to the support shaft 6 are fixedly connected with a clamp 13, the clamp 13 is sleeved on the outer periphery of the support shaft 6 and fixed by a locking handle 14. When in use, the laser displacement sensor 7 can move up and down a certain distance along the support shaft 6, and can also be rotated a certain angle, so that the emitted light can better cover tires of different diameters and widths, thereby improving its applicability.

[0046] See also Figure 4 The two mounting seats 8 are fixedly connected to the sides away from each other with shaft sleeves 15, and the inner wall of the shaft sleeve 15 is rotatably connected to the outer circumference of the corresponding tire shaft 11.

[0047] See also Figure 4The fixing mechanism 12 includes a screw rod 1201 fixed to the center position of one end of the tire shaft 11 away from the dual-axis motor 9, and a locking nut 1202 is threadedly connected to the outer periphery of the screw rod 1201.

[0048] See also Figure 4 A code disc 16 is fixedly connected to the outer periphery of the tire shaft 11, and a speed sensor 17 is fixedly installed on the mounting seat 8 corresponding to the position of the code disc 16. When in use, the surface of the code disc 16 is provided with uneven serrations, which can rotate simultaneously with the tire shaft 11, and the speed sensor 17 can detect the number of revolutions by the height change of the serrations on the code disc 16, and the tire speed can be obtained by calculation.

[0049] See also Figure 2 , the support frame 2 is located in the middle position of one side of the frame 1.

[0050] See also Figure 1 , the frame 1 is formed by splicing aluminum profiles.

[0051] Working principle:

[0052] The tire to be tested is installed on the wheel hub, and air of a certain pressure is filled to expand the tire. The tire and wheel hub are installed as a whole on the tire shaft 11. A screw 1201 is provided in the center of the tire shaft 11. The center hole of the wheel hub passes through the screw 1201 and is tightly attached to the end face of the tire shaft 11. At this time, the locking nut 1202 is screwed into the screw 1201 to tighten the tire; the tire shaft 11 is connected to the shaft sleeve 15, and the tire shaft 11 can rotate freely in the shaft sleeve 15. When the dual-axis motor 9 rotates, it can drive the two tire shafts 11 to rotate at the same time, thereby driving the tire to rotate. At this time, the code disk 16 rotates with the tire shaft 11 at the same time, and the speed sensor 17 is used to detect the height change of the saw teeth on the code disk 16 to detect the number of revolutions. The tire speed can be obtained by calculation;

[0053] After the tire is installed, the position of the laser displacement sensor 7 is set according to the diameter and width of the tire, and the X-direction and Y-direction positions of the laser displacement sensor 7 are adjusted using the X-direction linear module 3 and the Y-direction linear module 4, and then the locking handle 14 is loosened, and the laser displacement sensor 7 can move up and down a certain distance along the support shaft 6, and can also be rotated at a certain angle, so that the emitted light can better cover tires of different diameters and widths. After the adjustment is completed, the locking handle 14 is tightened to fix the laser displacement sensor 7;

[0054] The dual-axis motor 9 works, the tire rotates, and the light beam emitted by the laser displacement sensor 7 irradiates the tire surface. The distance between the tire surface and the laser emission point is different, and the angle of the reflected light received by the laser displacement sensor 7 is also different. The distance between the laser displacement sensor 7 and the measured tire is calculated according to the angle of the reflected light. When the tire rotates one circle, the laser displacement sensor 7 can completely scan the entire tread and sidewall of the tire. The upper computer calculates the tire cross-section contour curve and the shape and depth of the tread groove according to the measured distance. At the same time, the tire cross-section contour can be clearly displayed on the computer operation interface, and contour curves in various formats can be output;

[0055] The entire operation is convenient and fast, with strong applicability and high accuracy, which greatly improves the efficiency of its detection.
