Description

Technical Field

[0001] This application relates to the field of tire testing equipment technology, and in particular to an explosion-proof device for a tire machine tool durability testing machine. Background Technology

[0002] Tire performance and durability testing machines are used to detect abnormal deformations of tires during operation, such as local bulges, thereby identifying weak points in the tire and enabling performance enhancement of the corresponding parts of the tire.

[0003] Currently, tire machine tool performance durability testing machines in related technologies typically use metal wires surrounding the tire. The tire deformation is detected by observing the contact between the deformed tire and the metal wires.

[0004] However, the detection method of tire contact with metal wires has low sensitivity and is prone to situations where tire deformation is not detected in time, and the tire has already run to the point of bursting. It cannot reliably detect the tire and determine the weak point, and it also affects the safety of the test. Furthermore, a tire that has burst will also affect the accuracy of metal wire detection, and it is also difficult to determine the critical value of tire bursting.

[0005] The aforementioned technologies suffer from drawbacks such as low tire detection sensitivity and difficulty in determining the burst threshold. Utility Model Content

[0006] To address the issues of low tire testing sensitivity and difficulty in determining the burst threshold, this application provides an explosion-proof device for a tire machine tool durability testing machine.

[0007] The explosion-proof device for the tire machine tool durability testing machine provided in this application adopts the following technical solution:

[0008] An explosion-proof device for a tire machine tool durability testing machine includes: a support mechanism comprising a support frame and a support shaft, the support shaft being disposed on the support frame and used to support a tire; a drive mechanism disposed on a first side of the support mechanism and used to drive the tire to rotate; a shock-absorbing mechanism disposed on the side of the support shaft away from the drive mechanism; and a detection mechanism disposed on the shock-absorbing mechanism, the detection mechanism including a detection element and a terminal, the detection element being spaced apart on a second side of the support mechanism and spaced apart from the tire, the detection element being used to scan the shape of the tire, the terminal being disposed on the side of the detection element away from the support shaft, the terminal being electrically connected to the detection element, and the terminal being used to receive the scanned image of the detection element to determine the explosion threshold of the tire.

[0009] By adopting the above technical solutions, the support mechanism provides a stable foundation for the tire, ensuring the tire's stability during the test; the drive mechanism can effectively drive the tire to rotate, simulating the tire's operating state under actual working conditions; the shock absorption mechanism effectively absorbs and buffers the vibration generated by the tire during the durability test, reducing the risk of equipment damage; the testing mechanism scans the tire's shape through the testing component, and the terminal receives the scanned image to determine the tire's explosion threshold, thereby achieving accurate monitoring and evaluation of the tire's durability performance.

[0010] Optionally, the detection mechanism includes a comparison unit, which is a normal cross-sectional outline of the tire, and is used to compare it with the scanned image of the test piece.

[0011] By adopting the above technical solution, the normal cross-sectional shape of the tire can be used as a reference standard to compare with the scanned image of the test piece. This helps to accurately and intuitively judge the local bulge deformation of the tire in the durability test, providing a reliable basis for determining the tire's explosion threshold and improving the accuracy and safety of the test.

[0012] Optionally, the comparison unit is provided with a plurality of scale lines, which are distributed circumferentially on the normal cross-sectional outline of the tire.

[0013] By employing the above technical solution, precise division and quantification of the normal cross-sectional outline of a tire are achieved. By setting several scale lines in the comparison unit and distributing these scale lines circumferentially along the normal cross-sectional outline of the tire, the tire's shape can be scanned and compared more accurately. This design improves detection accuracy, ensures more reliable comparison results between the scanned image and the normal shape, and thus enhances the accuracy of identifying weak points.

[0014] Optionally, there are several control units, and the several control units have the same shape and increasing size.

[0015] By adopting the above technical solution, a more accurate comparison benchmark can be provided by several reference units with the same shape and increasing size. This helps to compare the scanned images of the test piece at different stages of the tire with the corresponding reference units according to the size, thereby more accurately judging the degree of local bulge deformation of the tire and improving the accuracy of identifying weak parts.

[0016] Optionally, it also includes an alarm mechanism electrically connected to the detection mechanism, the alarm mechanism being used to issue an alarm when there is a difference between the scanned image of the detection element and the shape of the control unit.

[0017] By adopting the above technical solution, the alarm mechanism can promptly sound an alarm when there is a difference between the scanned image of the test piece and the shape of the control unit, and promptly detect local bulge deformation of the tire, effectively preventing potential explosion risks and ensuring the safety of the test process.

[0018] Optionally, the shock absorption mechanism includes a support and a shock absorption pad, the detection mechanism is mounted on the support, and the support is mounted on the shock absorption pad.

[0019] By adopting the above technical solution, the shock absorption mechanism can effectively reduce the impact of the impact force generated during a tire explosion on the testing mechanism, reducing the risk of damage to the testing mechanism. Specifically, the bracket supports the testing mechanism, while the shock absorption pad absorbs and disperses the vibration energy generated by the explosion, ensuring the stability and safety of the testing mechanism.

[0020] Optionally, the bracket is provided with a receiving groove, and the detection mechanism is disposed in the receiving groove.

[0021] By adopting the above technical solution and placing the testing mechanism in the receiving groove of the support, the stability of the testing mechanism can be improved and the risk of the testing mechanism tipping over due to the impact of an explosion can be reduced.

[0022] Optionally, the sidewall of the receiving groove is provided with a through hole.

[0023] By adopting the above technical solution, the through holes on the side wall of the bracket's receiving groove can effectively reduce the pressure accumulation in the receiving groove, reduce the risk of overall movement caused by explosive impact, further improve the stability of the testing mechanism, and improve the accuracy of testing.

[0024] Optionally, the detection device is a three-dimensional laser scanner.

[0025] By adopting the above technical solution and using a 3D laser scanner as the inspection component, the tire's shape data can be accurately acquired, improving the accuracy of the scanned images. Combined with the support mechanism, drive mechanism, and shock absorption mechanism, the stability of the tire during durability testing is ensured, thus providing a reliable basis for subsequent determination of the explosion threshold. The use of a 3D laser scanner significantly improves inspection efficiency and accuracy, effectively reducing human error.

[0026] Optionally, the drive mechanism includes a drive motor, a drive shaft, and a drive wheel. The drive motor is located on the first side of the support mechanism, the drive shaft is connected to the drive motor, the drive wheel is located on the drive shaft, the drive motor drives the drive wheel to rotate through the drive shaft, the tread of the drive wheel is in contact with the tread of the tire, and the drive wheel is used to drive the tire to rotate.

[0027] By adopting the above technical solution, the drive mechanism can effectively drive the tire to rotate, thereby realizing the tire durability test. The drive motor is located on the first side of the support mechanism and is connected to the drive shaft, which can stably provide power and ensure the reliability of tire rotation. The drive wheel is linked to the drive motor through the drive shaft, and its tread is in contact with the tire tread, which can effectively transmit power, reduce slippage, and improve the accuracy of test data. The overall structure is reasonably designed, and all components work together to ensure the stable rotation of the tire during the test, providing a reliable basis for testing tire performance.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The drive mechanism rotates the tire, and the detection component scans the tire's shape. The terminal receives the scanned image to determine the tire's explosion threshold. This method can accurately capture the tire's subtle deformation during durability testing, effectively improving the accuracy of tire blowout risk warnings.

[0030] 2. The shock absorption mechanism can absorb the impact energy generated during a tire blowout, protecting the safety of the testing equipment and operators, while providing a stable installation environment for the testing organization and ensuring the reliability of the test results.

[0043] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0044] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of this application, an explosion-proof device for a tire machine tool durability testing machine (hereinafter referred to as the "device") is disclosed. The device includes a support mechanism 1, a drive mechanism 2, a shock absorption mechanism 3, and a detection mechanism 4.

[0046] The support mechanism 1 includes a support frame 11 and a support shaft 12. The support shaft 12 is mounted on the support frame 11 and is used to support the tire 100, allowing the tire 100 to rotate around its own axis. The support mechanism 1 provides a stable mounting foundation for the tire 100, ensuring the stability of the tire 100 during the test. The drive mechanism 2 is located on the first side of the axis between the support mechanism 1 and the tire 100. The drive mechanism 2 is used to drive the wheel 23 of the tire 100 to rotate, simulating the operating state of the tire 100 under actual working conditions. The shock absorption mechanism 3 is located on the side of the support shaft 12 away from the drive mechanism 2, that is, on the second side of the axis between the support mechanism 1 and the tire 100. The shock absorption mechanism 3 can absorb and buffer the vibration generated by the tire 100 during the durability test, reducing the risk of equipment damage.

[0047] like Figure 1 , Figure 2 and Figure 3 As shown, the detection mechanism 4 is mounted on the shock absorption mechanism 3. The detection mechanism 4 includes a detection element 41 and a terminal 42. The detection element 41 is located on the second side of the support mechanism 1. The detection element 41 is used to scan the shape of the tire 100. The detection element 41 is spaced apart from the tire 100 to reduce the impact of a tire blowout on the detection element 41. The terminal 42 is located on the side of the detection element 41 away from the support shaft 12. The terminal 42 is electrically connected to the detection element 41 and is used to receive the scanned images from the detection element 41 to determine the critical value for tire 100 to explode. The detection mechanism 4 scans the shape of the tire 100 in real time through the detection element 41, and the terminal 42 receives the scanned images of the tire 100 at different time points during its operation to determine the critical value for tire 100 to explode, thereby achieving accurate monitoring and evaluation of the durability performance of the tire 100.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the drive mechanism 2 includes a drive motor 21, a drive shaft 22, and a drive wheel 23. The drive motor 21 is located on the first side of the support mechanism 1, and the drive shaft 22 is connected to the drive motor 21 to stably provide power and ensure the reliability of the tire 100's rotation. The drive wheel 23 is located on the drive shaft 22, and the drive motor 21 drives the drive wheel 23 to rotate through the drive shaft 22. The tread of the drive wheel 23 is in contact with the tread of the tire 100, which can effectively transmit power and drive the tire 100 to rotate, improving the accuracy of the test data. The overall structure is reasonably designed, and the components work together to ensure the stable rotation of the tire 100 during the test, providing a reliable basis for testing the performance of the tire 100.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the inspection component 41 is a three-dimensional laser scanner. Using a three-dimensional laser scanner as the inspection component 41 allows for the accurate acquisition of the tire 100's shape data, improving the accuracy of the scanned image and thus providing a reliable basis for subsequent determination of the explosion threshold. Simultaneously, the use of a three-dimensional laser scanner significantly improves inspection efficiency and accuracy, effectively reducing human error.

[0050] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the testing mechanism 4 includes a reference unit 43, which is the normal cross-sectional outline of the tire. The reference unit 43 is used to compare the tire 100 with the real-time scanned image of the test piece 41. By using the normal cross-sectional outline of the tire 100 as a reference standard, comparison with the scanned image of the test piece 41 can be achieved. This helps to accurately and intuitively judge abnormal deformations such as local bulges of the tire 100 during the durability test, providing a reliable basis for determining the explosion threshold of the tire 100 and improving the accuracy and safety of the test.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the comparison unit 43 is provided with a plurality of scale lines 431, which are distributed circumferentially along the normal cross-sectional outline of the tire 100, to achieve precise division and quantification of the normal cross-sectional outline of the tire 100. The scale lines 431 can be labeled with numbers to accurately and clearly determine the location of any abnormal protrusion. This design improves detection accuracy, ensures more reliable comparison results between the scanned image and the normal outline, and thus improves the accuracy of identifying weak points.

[0052] Optionally, several comparison units 43 are provided, with the same shape and increasing size to form similar graphics. Using several comparison units 43 with the same shape and increasing size provides a more accurate comparison benchmark, helping to compare the scanned images of the test piece 41 at different times of the tire 100 with the corresponding comparison units 43 according to size, thereby more accurately determining the degree of local abnormal bulge deformation of the tire 100 and improving the accuracy of identifying weak points. In this embodiment, the comparison unit 43 can be a graphic module located within the terminal 42 for comparison by the terminal 42; in other embodiments, the comparison unit 43 can also be a graphic drawn on a transparent plate, which the terminal 42 scans with another scanner to achieve comparison with the test results. The appropriate method can be selected according to the actual situation.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the shock absorption mechanism 3 includes a bracket 31 and a shock absorption pad 32. The detection mechanism 4 is mounted on the bracket 31, and the bracket 31 is mounted on the shock absorption pad 32. The shock absorption mechanism 3 can effectively reduce the impact of the impact force generated when the tire 100 explodes on the detection mechanism 4, reducing the risk of damage to the detection mechanism 4. The bracket 31 supports the detection mechanism 4, and the shock absorption pad 32 absorbs and disperses the vibration energy generated by the explosion, ensuring the stability and safety of the detection mechanism 4.

[0054] Optionally, the support 31 is provided with a receiving groove 33, and the detection mechanism 4 is disposed in the receiving groove 33, so that the legs of the detection mechanism 4 abut against the side wall of the receiving groove 33, which can improve the stability of the detection mechanism 4 and reduce the risk of the detection mechanism 4 tipping over due to explosive impact. Optionally, the side wall of the receiving groove 33 is provided with a through hole 331, which can effectively reduce the pressure accumulation in the receiving groove 33, reduce the risk of overall movement due to explosive impact, further improve the stability of the detection mechanism 4, and improve the detection accuracy.

[0055] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the device also includes an alarm mechanism 5, which is electrically connected to the detection mechanism 4. The alarm mechanism 5 is used to sound an alarm when there is a difference between the scanned image of the test piece 41 and the shape of the control unit 43, so as to promptly detect local bulge deformation of the tire 100, effectively prevent potential explosion risks, and ensure the safety of the test process. The terminal 42 can be a PLC, which can receive the detection results of the test piece 41 and compare the detection results with the control unit 43 with the closest size to determine whether the tire 100 has a local abnormal bulge. Under normal circumstances, the detection result image of the tire 100 is as follows: Figure 4 As shown, if the surface is uniform and there are no bulges, chips, or other surface damage, the tire is 100% normal. If local bulges occur, such as... Figure 5 As shown, the shadow on the outer periphery of tire 100 in the figure represents a localized protrusion. At this point, after comparison between terminal 42 and control unit 43, the alarm mechanism 5 will be activated. Terminal 42 can also record the detection results of tire 100 before a blowout, so as to obtain the tire 100's shape data at the explosion threshold through the last image. The alarm mechanism 5 can be an audible and visual alarm to promptly alert the operator.

[0056] During testing, a detection-sensing light layer, i.e., a sensor layer detectable by laser or other means, can be set around the outer periphery of the tire 100 being tested. This allows for the detection of the tire 100's outline when scanning its surface, enabling real-time monitoring of changes and timely detection of abnormal deformation. Compared to related technologies where physical detection devices require close proximity to the tire 100 for effective detection, and where tire 100 damage and bursting can cause deformation of the detection object, this device, with its remote detection capability, will not be damaged even if the tire 100 bursts, thus improving reliability. The device can immediately detect even slight bulging of the tire 100, issuing a timely warning and automatically shutting down. Early detection of weak points in the tire 100 facilitates accurate determination of the cause of damage. Under high-speed, high-pressure operating conditions, the device can automatically activate its alarm and shutdown protection mechanism to prevent explosions and ensure operator safety. Even under prolonged operation and periods of increased load, the device maintains stable operation, extending its service life. It is understandable that the device also includes necessary structures for connection, support, drive, positioning, limiting and control functions, so that the device can operate normally; the shape, size, material and number of each part of the device can be determined as needed, as long as the corresponding functions can be achieved.

[0057] The implementation principle of the explosion-proof device for a tire machine tool durability testing machine according to this application embodiment is as follows: Through the cooperation of the support mechanism 1, drive mechanism 2, shock absorption mechanism 3 and detection mechanism 4, the tire 100 can be stably tested for durability; by scanning the shape of the tire 100 through the detection component 41, and comparing the scanned image with the reference unit 43 through the terminal 42, the changes in the shape of the tire 100 can be accurately judged, the weak parts of the tire 100 can be found, and the explosion threshold of the tire 100 can be determined through the terminal 42; the alarm mechanism 5 can promptly alarm when there is a difference between the scanned image of the detection component 41 and the shape of the reference unit 43, effectively preventing potential explosion risks and ensuring the safety of the test process.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
