Description

Technical Field

[0001] This application relates to the field of measurement technology, and in particular to a method for measuring the vulcanized bushings of a tire. Background Technology

[0002] A vulcanizing bushing, also known as a vulcanizing bladder, is a hollow, thin-walled rubber product made of high-performance rubber composite materials. During the vulcanization process of tires, it is installed inside the tire vulcanizing machine as an inner mold for tire shaping. Compressed air, nitrogen, or superheated water is injected into the vulcanizing bushing, causing it to stretch and support the tire blank, thus ensuring it adheres to the tire lining. Utilizing the heat transfer characteristics of the fluid flow inside the vulcanizing bushing, a relatively uniform temperature is maintained during the vulcanization process, achieving uniform vulcanization and improving the tire's balance performance.

[0003] To prevent uneven wear of the vulcanized bushing from affecting its levelness and thus the quality of tire vulcanization, the vulcanized bushing needs to be measured and inspected regularly. The levelness of the vulcanized bushing is often measured using a combination of a measuring plate and a dial indicator. First, the vulcanized bushing is placed stably on a measuring platform. Then, multiple points on the vulcanized bushing are recorded using the measuring plate and dial indicator. The difference between the maximum and minimum values ​​is taken as the flatness error of the flange surface, which is the quantitative indicator of its levelness. However, this method involves arbitrary selection of recording points, which can lead to inaccurate data. Furthermore, this method requires manual measurement and reading by eye, which can result in significant errors and is time-consuming and labor-intensive. Summary of the Invention

[0004] This application proposes a method for measuring vulcanized axle sleeves of tires, which effectively optimizes the measurement method of vulcanized axle sleeves, not only improving measurement accuracy but also saving time and effort, thereby solving the problems of insufficient measurement accuracy and time-consuming and labor-intensive measurement.

[0005] To achieve the above objectives, this application adopts the following technical solution: a method for measuring the vulcanization of tire bushings, comprising: A fixing mechanism, wherein a vulcanized bushing is provided inside the fixing mechanism; Telescopic mechanism, wherein the top of the left and right ends of the fixed mechanism are both fixedly connected to the telescopic mechanism; The top ends of both telescopic mechanisms are fixedly connected to the bottom end of the movable plate. A rotating assembly is fixedly installed in the middle of the movable plate; The measuring component is provided at both ends of the rotating component; A connecting component is fixedly connected to the bottom end of the movable plate, and the movable plate and the connecting component are coaxially arranged. The measuring component is slowly rotated by a rotating component. Since the lower half of the measuring component is in contact with the top surface of the vulcanized bushing and the upper half of the measuring component is in contact with the connecting component, the measuring component can move vertically according to the levelness of the vulcanized bushing when it rotates, so as to form a continuous curve on the connecting component, thereby dynamically recording the data of the vulcanized bushing.

[0006] Furthermore, it also includes: The measuring platform has a working groove at its top, and the working groove of the measuring platform is movably engaged with the bottom surface of the vulcanizing bushing.

[0007] Furthermore, the rotating assembly includes: A rotary motor is fixedly installed at the top center of the movable plate; A rotating shaft, one end of which is movably connected to a rotating motor, and the other end of which passes through a movable plate; A rotating plate is fixedly connected to the top of the rotating plate via the end of the rotating shaft of the moving plate.

[0008] Furthermore, the measurement component includes: The measuring component has vertical holes at both ends of the rotating plate, and the rotating plate is movably connected to the measuring component through the vertical holes; A spring is used to connect the upper and lower ends of the measuring element to the rotating plate; The measuring component has a recording pen attached to its upper end, with the lower end face of the measuring component abutting against the top surface of the vulcanized bushing.

[0009] Furthermore, the connection component includes: A connecting frame, the top end of which is fixedly connected to the bottom end of the movable plate; The bottom end of the connecting frame is fixedly connected to the connecting seat by connecting bolts; The recording component has a connecting cavity in the inner ring of the connecting frame and the connecting seat, and the connecting frame and the connecting seat are movably connected to the recording component through the connecting cavity.

[0010] Furthermore, the moving plate, rotating assembly, measuring assembly, and connecting assembly together constitute the moving mechanism.

[0011] Furthermore, the fixing mechanism includes: A fixed plate is fixedly connected to the top of the measuring platform by fixing bolts at its front and rear ends. The vulcanizing bushing is movably sleeved inside the fixed plate, and the top surface of the fixed plate is in contact with the wall surface of the vulcanizing bushing. The fixing bladder has an annular groove on the inner side of the top of the fixing plate, and the annular groove of the fixing plate is fixedly connected to the bottom and outer sides of the fixing bladder. The wall of the vulcanized bushing is in contact with the top and inner sides of the fixing bladder. The fixing bladder is made of rubber.

[0012] Furthermore, the telescopic mechanism includes: A telescopic cylinder, the bottom end of which is fixedly connected to the top end of a fixed plate; The telescopic shaft is provided, with the top end of the telescopic cylinder movably connected to the bottom end of the telescopic shaft, and the top end of the telescopic shaft being fixedly connected to the bottom end of the moving plate.

[0013] Furthermore, the fixing mechanism also includes: The movable bladder is movably sleeved on the outside of the telescopic shaft, and the bottom end of the movable bladder is fixedly connected to the top surface of the telescopic cylinder and the bottom end of the movable bladder is fixedly connected to the bottom surface of the moving plate. The movable bladder is made of rubber and is filled with gas. A fixing tube, one end of which is fixedly connected to the interior of the movable bladder, and the other end of which passes through a fixing plate and is fixedly connected to the interior of the fixing bladder.

[0014] Furthermore, a method for measuring the vulcanized axle sleeve of a tire includes the following steps: S1. Place the vulcanized bushing on the measuring platform and ensure that the bottom end of the vulcanized bushing is locked in the working groove of the measuring platform, and that the wall of the vulcanized bushing is limited and supported by the fixing mechanism. S2. Activate the telescopic mechanism to drive the moving mechanism to move downward until it stops at the limited working height. At the same time, the fixed bladder expands under the action of the movable bladder. S3. Start the rotating component and slowly rotate the measuring component 180 degrees; S4. During this process, the lower end of the measuring piece abuts against the vulcanized bushing, while the upper end of the measuring piece is equipped with a recording pen, and the recording pen contacts the recording piece, thereby recording the level of the vulcanized bushing on the recording piece in the form of continuous line segments. As the measuring piece rotates, it can move vertically on the rotating plate according to the level of the top surface of the vulcanized bushing, thereby dynamically recording the level data of the vulcanized bushing. S5. After the measurement is completed, start the telescopic mechanism to drive the moving mechanism to move upward until it reaches the specified working height and then stop, and remove the vulcanized bushing. S6. Disassemble the connector to remove the record from the connector frame and analyze the data.

[0015] The beneficial effects of this invention are as follows: This application provides a method for measuring the levelness of a vulcanized axle sleeve of a tire. A fixing mechanism, a telescopic mechanism, and a moving mechanism are installed at the top of a measuring platform and outside the vulcanized axle sleeve. The moving mechanism consists of a moving plate, a rotating component, a measuring component, and a connecting component. When the levelness of the vulcanized axle sleeve needs to be measured, the rotating component drives the measuring component to rotate slowly. The lower half of the measuring component contacts the top surface of the vulcanized axle sleeve, and the upper half contacts the connecting component. The measuring component can move vertically on the rotating plate according to the levelness of the vulcanized axle sleeve, thereby dynamically recording the levelness data of the vulcanized axle sleeve on a recording device. This allows workers to intuitively perceive the dynamic changes in levelness. This not only effectively increases the quantity of levelness data, thereby improving data accuracy and solving the problem of inaccurate data due to arbitrary selection and small sample sizes, but also effectively changes the measurement method, transforming manual measurement into automated measurement, saving time and effort while ensuring accurate readings.

[0016] By setting up a fixed mechanism and a telescopic mechanism, the fixed mechanism consists of a fixed plate, a fixed bladder, a movable bladder, and a fixed tube, while the telescopic mechanism consists of a telescopic cylinder and a telescopic shaft. When it is necessary to disassemble or assemble the vulcanized bushing, the telescopic mechanism can be controlled to move the moving mechanism, thereby effectively ensuring the stability and horizontality of the moving mechanism. In addition, when the telescopic mechanism moves downward, it can compress the movable bladder, allowing the gas in the movable bladder to be discharged into the fixed bladder through the fixed tube, further improving the stability of the fixed mechanism in clamping the vulcanized bushing. When the telescopic mechanism moves upward, it can stretch the movable bladder, allowing the gas in the fixed bladder to return to the movable bladder through the fixed tube, facilitating the disassembly and assembly of the vulcanized bushing.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: A method for measuring the vulcanization of tire bushings, including a measuring platform 1, such as... Figures 1-2 , Figures 4-5 The top of the measuring platform 1 is provided with a working groove, and the working groove of the measuring platform 1 is movably engaged with the bottom surface of the vulcanized bushing 2, which effectively ensures the stability of the vulcanized bushing 2 and the concentricity of the vulcanized bushing 2 and the components on the measuring platform 1.

[0021] like Figures 1-2 , Figures 6-7 The fixing mechanism 3 is set on the measuring platform 1 and is coaxially set with the vulcanized bushing 2. The fixing mechanism 3 is used to clamp and fix the vulcanized bushing 2, which effectively ensures the stability of the vulcanized bushing 2 during the measurement process.

[0022] like Figures 1-2 , Figures 6-7 The top of the left and right ends of the fixed mechanism 3 are fixedly connected to the telescopic mechanism 4, which can provide the power source for driving the moving mechanism 5 to move up and down.

[0023] like Figures 1-2 , Figures 8-10 A moving mechanism 5 is fixedly installed at the top of the telescopic mechanism 4. The moving mechanism 5 allows for stable measurement of the levelness of the vulcanized bushing 2, eliminating the need for manual measurement. This effectively improves measurement accuracy and saves time and effort. The moving mechanism 5 includes a moving plate 51, a rotating assembly 6, a measuring assembly 7, and a connecting assembly 8. Specifically, as follows... Figures 2-3 The top ends of the two telescopic mechanisms 4 are fixedly connected to the bottom end of the movable plate 51. A rotating component 6 is fixedly installed in the middle of the movable plate 51. Measuring components 7 are movably installed at both ends of the rotating component 6. A connecting component 8 is fixedly connected to the bottom end of the movable plate 51, and the movable plate 51 and the connecting component 8 are coaxially arranged.

[0024] like Figures 2-3 , Figures 8-9 The rotating component 6 includes a rotating motor 61, a rotating shaft 62, and a rotating plate 63. The rotating motor 61 is fixedly installed at the top center of the moving plate 51. One end of the rotating shaft 62 is movably connected to the rotating motor 61, and the other end of the rotating shaft 62 passes through the moving plate 51. The end of the rotating shaft 62 passing through the moving plate 51 is fixedly connected to the top of the rotating plate 63. When the rotating motor 61 is started, it can drive the rotating shaft 62 to rotate, thereby driving the rotating plate 63 to rotate, so as to provide power for the circumferential measurement of the vulcanized bushing 2 of the measuring component 7. It should be noted that the rotating component 6 rotates slowly each time, and stops after rotating 180 degrees each time, so as to ensure that the connecting component 8 can obtain accurate dynamic line segment data.

[0025] like Figures 2-3 , Figures 8-9 The measuring component 7 includes a measuring element 71, a spring 72, and a recording pen 73. Vertical holes are provided at both ends of the rotating plate 63, which is movably connected to the measuring element 71 through these holes. The upper and lower ends of the measuring element 71 are connected to the rotating plate 63 via the spring 72. The lower end face of the measuring element 71 abuts against the top surface of the vulcanized bushing 2. The upper end of the measuring element 71 is threaded with the recording pen 73. It should be noted that the ink in the recording pen 73 can be replaced with a new one after it runs out. When the rotating plate 63 rotates, the lower end face of the measuring element 71 remains in contact with the top surface of the vulcanized bushing 2 due to the spring 72. Therefore, if the levelness of the top surface of the vulcanized bushing 2 changes, the measuring element 71 will move vertically, allowing the recording pen 73 to record the data completely. In summary, the measuring component 7 can obtain all the levelness data of the vulcanized bushing 2 and provide a direct visual understanding of the dynamic changes in levelness, effectively improving the accuracy of the data.

[0026] like Figures 2-3 , Figure 8 , Figure 10The connecting component 8 includes a connecting frame 81, a connecting seat 82, and a recording component 83. The top end of the connecting frame 81 is fixedly connected to the bottom end of the movable plate 51, and the bottom end of the connecting frame 81 is fixedly connected to the connecting seat 82 by connecting bolts. The inner rings of the connecting frame 81 and the connecting seat 82 are jointly provided with a connecting cavity, and the connecting frame 81 and the connecting seat 82 are movably connected to the recording component 83 through the connecting cavity. The recording component 83 is a sheet of paper marked with height lines. Each time a measurement is taken, the height of the recording component 83 corresponds to the height line marked on it. Thus, the lines drawn by the recording pen 73 on the recording component 83 can record the horizontal state of the top surface of the vulcanized bushing 2, thereby allowing a direct perception of the dynamic changes in the levelness.

[0027] In summary, by using the rotating component 6 to drive the measuring component 7 to rotate slowly, and because the lower half of the measuring component 7 contacts the top surface of the vulcanized bushing 2 and the upper half of the measuring component 7 contacts the connecting component 8, the measuring component 7 can move vertically according to the levelness of the vulcanized bushing 2 during rotation, so as to form a continuous curve on the connecting component 8, thereby dynamically recording the data of the vulcanized bushing 2. This allows for a more intuitive understanding of the dynamic changes in levelness. This not only effectively increases the amount of levelness data collected and improves data accuracy, solving the problem of inaccurate data due to arbitrary selection and small quantity, but also effectively changes the measurement method, transforming manual measurement into automated measurement, which is both time-saving and labor-saving while ensuring measurement accuracy.

[0028] Example 2, based on Example 1, such as Figures 1-2 , Figure 4 , Figures 6-7 The fixing mechanism 3 includes a fixing plate 31 and a fixing bladder 32. The front and rear ends of the fixing plate 31 are fixedly connected to the top of the measuring platform 1 by fixing bolts. The vulcanized bushing 2 is movably sleeved inside the fixing plate 31, and the top surface of the fixing plate 31 is in contact with the wall surface of the vulcanized bushing 2. Thus, the fixing plate 31 can stably support the vulcanized bushing 2 and ensure the stability of the vulcanized bushing 2 in vertical setting. An annular groove is opened on the inner side of the top of the fixing plate 31, and the annular groove of the fixing plate 31 is fixedly connected to the bottom surface and the outer surface of the fixing bladder 32. The wall surface of the vulcanized bushing 2 is in contact with the top surface and the inner surface of the fixing bladder 32. The fixing bladder 32 is made of elastic rubber material, thus the fixing bladder 32 can reduce the gap between the vulcanized bushing 2 and the fixing mechanism 3 and improve the stability of the vulcanized bushing 2.

[0029] like Figures 1-2 , Figures 6-7The telescopic mechanism 4 includes a telescopic cylinder 41 and a telescopic shaft 42. The bottom end of the telescopic cylinder 41 is fixedly connected to the top end of the fixed plate 31, and the top end of the telescopic cylinder 41 is movably sleeved with the bottom end of the telescopic shaft 42. The top end of the telescopic shaft 42 is fixedly connected to the bottom end of the moving plate 51. The telescopic cylinder 41 can drive the telescopic shaft 42 to move up and down, thereby driving the moving mechanism 5 to move vertically. Specifically, when the vulcanized bushing 2 needs to be installed on the measuring platform 1 or removed from the measuring platform 1, the telescopic mechanism 4 needs to be stretched to drive the moving mechanism 5 to move upward, thus facilitating the loading and unloading of the vulcanized bushing 2. When the vulcanized bushing 2 needs to be measured, the telescopic mechanism 4 needs to be compressed to drive the moving mechanism 5 to move downward, thus facilitating the moving mechanism 5 to measure the vulcanized bushing 2.

[0030] like Figures 1-2 , Figure 4 , Figures 6-7 The fixing mechanism 3 also includes a movable bladder 33 and a fixing tube 34. The movable bladder 33 is movably sleeved on the outside of the telescopic shaft 42, and the bottom end of the movable bladder 33 is fixedly connected to the top surface of the telescopic cylinder 41. The bottom end of the movable bladder 33 is also fixedly connected to the bottom surface of the moving plate 51. The movable bladder 33 is made of elastic rubber and is filled with gas. One end of the fixing tube 34 is fixedly connected to the inside of the movable bladder 33, and the other end of the fixing tube 34 passes through the fixing plate 31 and is fixedly connected to the inside of the fixing bladder 32. The fixing tube 34 is the component connecting the movable bladder 33 and the fixing bladder 32. The amount of gas in the fixing bladder 32 can be changed by using the movable bladder 33, thereby changing the expansion of the fixing bladder 32. Specifically, when the moving plate 51 moves downward, the movable bladder 33 can be compressed, allowing the gas inside the movable bladder 33 to be discharged into the fixed bladder 32 through the fixed tube 34. This increases the amount of gas in the fixed bladder 32, enhancing the fit between the fixed bladder 32 and the vulcanized bushing 2, thereby further improving the stability of the clamping mechanism 3 on the vulcanized bushing 2 and preventing the vulcanized bushing 2 from moving and affecting the measurement of its levelness. When the moving plate 51 moves upward, the movable bladder 33 can be stretched, allowing the gas inside the fixed bladder 32 to return to the movable bladder 33 through the fixed tube 34. This reduces the amount of gas in the fixed bladder 32, weakening the fit between the fixed bladder 32 and the vulcanized bushing 2, thus facilitating the assembly and disassembly of the vulcanized bushing 2.

[0031] Example 3, based on Example 2, provides a method for measuring the vulcanization of tire bushings, such as... Figures 1-10 This includes the following steps: S1. Place the vulcanized bushing 2 on the measuring platform 1, and ensure that the bottom end of the vulcanized bushing 2 is stuck in the working groove of the measuring platform 1, and that the wall of the vulcanized bushing 2 is limited and supported by the fixing mechanism 3.

[0032] S2. Start the telescopic mechanism 4 to drive the moving mechanism 5 to move down until it reaches the limited working height and stops. At the same time, the fixed bladder 32 expands under the action of the movable bladder 33 to facilitate the stable clamping of the vulcanized bushing 2.

[0033] S3. Start the rotating component 6 and slowly rotate the measuring component 7 180 degrees to ensure stable and accurate data recording.

[0034] S4. During this process, the lower end of the measuring element 71 abuts against the vulcanized bushing 2, while the upper end of the measuring element 71 is provided with a recording pen 73, and the recording pen 73 contacts the recording element 83, thereby recording the levelness of the vulcanized bushing 2 on the recording element 83 in the form of continuous line segments. Because the measuring element 71 can move vertically on the rotating plate 63 according to the levelness of the top surface of the vulcanized bushing 2 when rotating, the levelness data of the vulcanized bushing 2 is dynamically recorded, which makes it easier for the staff to intuitively feel the dynamic changes in levelness, reduce the difficulty of data acquisition, and improve the accuracy of measurement data.

[0035] S5. After the measurement is completed, start the telescopic mechanism 4 to drive the moving mechanism 5 to move upward until it reaches the specified working height and stops. Then remove the vulcanized bushing 2 to prepare for the next measurement.

[0036] S6. Disassemble the connector 82 to remove the recorder 83 from the connector frame 81 and analyze the data to determine whether the level of the vulcanized bushing 2 meets the standard and whether it needs to be replaced.

[0037] The working principle of the method of using this invention is as follows: When installing the vulcanized bushing 2, first place the vulcanized bushing 2 on the measuring platform 1, ensuring that the bottom end of the vulcanized bushing 2 is locked in the working groove of the measuring platform 1, and that the wall of the vulcanized bushing 2 is limited and supported by the fixing mechanism 3. Then, start the telescopic mechanism 4 to drive the moving mechanism 5 to move down until it moves to the limited working height and stops. At the same time, the movable bladder 33 is compressed, so that the gas in the movable bladder 33 is discharged into the fixed bladder 32 through the fixing pipe 34. The amount of gas in the fixed bladder 32 increases and expands, further improving the stability of the fixing mechanism 3 in clamping the vulcanized bushing 2, so as to achieve stable clamping of the vulcanized bushing 2.

[0038] When measuring the vulcanized bushing 2, the rotating assembly 6 is activated, which slowly drives the measuring assembly 7 to rotate 180 degrees. During this process, because the lower end of the measuring component 71 abuts against the vulcanized bushing 2, and the upper end of the measuring component 71 is equipped with a recording pen 73, which contacts the recording component 83, the levelness of the vulcanized bushing 2 is recorded on the recording component 83 as a continuous line segment. Furthermore, because the measuring component 71 can move vertically on the rotating plate 63 according to the levelness of the top surface of the vulcanized bushing 2 during rotation, the continuous line segment can be transformed into a dynamic curve. This completely records the levelness data of the vulcanized bushing 2, making it easier for staff to intuitively perceive the dynamic changes in levelness, reducing the difficulty of data acquisition, and improving the accuracy of measurement data. This solves the problem of inaccurate data due to arbitrary selection and insufficient data comparison. At the same time, it transforms manual measurement into automated measurement, saving time and effort while ensuring accurate readings.

[0039] After the measurement is completed, the telescopic mechanism 4 is activated to move the moving mechanism 5 upward until it reaches the specified working height and stops. Then, the vulcanized bushing 2 is removed to prepare for the next measurement. In addition, the connecting seat 82 is disassembled to remove the recording piece 83 from the connecting frame 81, and the data is analyzed to determine whether the levelness of the vulcanized bushing 2 meets the standard and whether it needs to be replaced.

10. The method for measuring the vulcanized axle sleeve of a tire according to claim 9, characterized in that, Includes the following steps: S1. Place the vulcanized bushing (2) on the measuring platform (1) and ensure that the bottom end of the vulcanized bushing (2) is stuck in the working groove of the measuring platform (1) and the wall of the vulcanized bushing (2) is limited and supported by the fixing mechanism (3). S2. Start the telescopic mechanism (4) to drive the moving mechanism (5) to move down until it reaches the specified working height and stops. At the same time, the fixed bladder (32) expands under the action of the movable bladder (33). S3. Start the rotating component (6) and slowly drive the measuring component (7) to rotate 180 degrees; S4. During this process, the lower end of the measuring piece (71) abuts against the vulcanized bushing (2), and the upper end of the measuring piece (71) is provided with a recording pen (73), and the recording pen (73) contacts the recording piece (83), thereby recording the level of the vulcanized bushing (2) on the recording piece (83) in the form of continuous line segments. Since the measuring piece (71) can move vertically on the rotating plate (63) according to the level of the top surface of the vulcanized bushing (2) when rotating, the level data of the vulcanized bushing (2) is dynamically recorded. S5. After the measurement is completed, start the telescopic mechanism (4) to drive the moving mechanism (5) to move upward until it reaches the specified working height and then stop, and take out the vulcanized bushing (2). S6. Disassemble the connector (82) to remove the record (83) from the connector (81) and analyze the data.
