Description

Technical Field

[0001] The utility model belongs to the technical field of bellows measurement, and in particular relates to a bellows pitch thickness measuring device. Background Art

[0002] The bellows pitch and thickness measuring device is a precision measuring tool that can accurately measure the pitch (i.e. the distance from the crest to the trough of the bellows) and thickness (the wall thickness of the pipe) of the bellows. This device is widely used in pipeline manufacturing, quality inspection, project acceptance and other fields.

[0003] However, traditional devices can often only measure a single position of the bellows, and multiple adjustments or movements of the bellows are required to complete the measurement of the entire length, which greatly increases the time required for measurement. The lack of an automated clamping mechanism requires frequent manual adjustments to the clamping position during the measurement process, reducing measurement efficiency. When manually clamping the bellows, uneven force or difficulty in accurately controlling the clamping force may cause unstable contact between the inner wall of the bellows and the measuring device, thereby affecting the accuracy of the measurement results.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1 As shown:

[0028] A bellows pitch thickness measuring device comprises an annular structure 1.

[0029] In this embodiment: However, traditional devices can often only measure a single position of the bellows, and the bellows needs to be adjusted or moved multiple times to complete the measurement of the entire length, which greatly increases the time required for measurement. The lack of an automated clamping mechanism requires frequent manual adjustment of the clamping position during the measurement process, reducing the measurement efficiency. When the bellows is manually clamped, the uneven force or the difficulty in accurately controlling the clamping force may cause unstable contact between the inner wall of the bellows and the measuring device, thereby affecting the accuracy of the measurement results. In order to solve this technical problem, a measuring component 2 is added on this basis.

[0030] More specifically:

[0031] like Figures 1 to 5 As shown:

[0032] In combination with the above content: the base 21 is fixedly connected to the inner side of the bottom end of the annular structure 1, the telescopic rod 22 is installed on the upper surface of the end of the base 21, the fixed ring 23 is slidably connected to the outer side of the end of the telescopic rod 22, the lower surface of the fixed ring 23 is fixedly connected to the outer side of the end of the telescopic rod 22, the rotating rod 24 is rotatably connected to the inner side of the top end of the fixed ring 23, the sliding block 25 is rotatably connected to the outer side of the end of the rotating rod 24, the first measuring plate 26 is fixedly connected to the upper surface of the sliding block 25, the placement plate 28 is fixedly connected to the outer side of the top end of the base 21, the second measuring plate 27 is fixedly connected to the upper surface of the end of the placement plate 28, one side of the placement plate 28 is fixedly connected to a plurality of scale plates 29, the middle of the placement plate 28 The upper surface is fixedly connected with an insertion rod 210, the outer side of the end of the annular structure 1 is fixedly connected with a fixed frame 211, the outer side of the end of the fixed frame 211 is rotatably connected with a rotating handle 212, the outer middle part of the rotating handle 212 is rotatably connected with a first rotating arm 213, the inner side of the end of the first rotating arm 213 is rotatably connected with a second rotating arm 214, the inner side of one end of the second rotating arm 214 is rotatably connected to one side of the fixed frame 211, the inner middle part of the second rotating arm 214 is rotatably connected to the third rotating arm 217, the inner side of the fixed frame 211 is slidably connected with a sliding rod 215, the outer side of the end of the third rotating arm 217 is rotatably connected to the outer side of the sliding rod 215, and a cross structure is provided at the bottom end of the annular structure 1.

[0033] When the user presses the lever 214, the first and second measuring plates 26 and 27 are in contact with each other, and the second and second measuring plates 27 are in contact with each other, so that the user can adjust the position of the measuring plate 26 so that the measuring plate 26 is in contact with the measuring plate 27. The bellows is limited by the clamping plate 216. When the user needs to measure the pitch of the bellows, the user only needs to adjust the bellows to a horizontal state and place one side of the bellows between the first measuring plate 26 and the second measuring plate 27 to measure the pitch. Through multiple independent measuring units, each unit can independently and simultaneously measure different positions of the bellows, which not only greatly improves the measurement efficiency but also ensures the consistency of measurement data at different positions of the entire bellows. The clamping main device of the slide rod 215 can automatically adjust to adapt to bellows of different diameters and wall thicknesses. This adaptive clamping mechanism ensures stable contact with the inner wall of the bellows during measurement and reduces measurement errors caused by improper human operation. The self-locking design of the first rotating arm 213 and the second rotating arm 214 automatically locks after completing the clamping action, ensuring that the bellows remains stable and motionless during measurement. This not only improves the stability of the measurement but also avoids measurement errors caused by vibration or external force interference.

[0034] Going further:

[0035] In an optional embodiment, a clamping plate 216 is fixedly connected to the outer side of the end of the sliding rod 215, and the clamping plate 216 is an arc-shaped structure.

[0036] In this embodiment, the fan-shaped clamping plate 216 has many significant advantages in measuring the pitch and thickness of the bellows. First, the fan-shaped structure can better fit the curved surface of the inner wall of the bellows, especially when the bellows has a complex waveform or a large diameter change. This design can ensure that the contact area between the clamping plate 216 and the inner wall of the bellows is larger and more uniform, thereby improving the stability and accuracy of the measurement. Second, the fan-shaped clamping plate 216 can gradually apply force during the clamping process, gradually wrapping the bellows in a fan-shaped manner. The fan-shaped design can effectively reduce the deformation or damage of the bellows that may be caused by the sudden application of clamping force. In addition, the fan-shaped design also facilitates the realization of multi-stage or adjustable clamping force to adapt to bellows of different materials, wall thicknesses and diameters, further enhancing the versatility and flexibility of the clamping plate 216. Finally, the fan-shaped clamping plate 216 is also more compact and beautiful in appearance, which helps to reduce the volume and weight of the entire measuring device and facilitates installation, movement and maintenance. Therefore, the fan-shaped structure of the clamping plate 216 is an important innovation to improve the measurement accuracy, efficiency and safety of bellows.

[0037] Going further:

[0038] In an optional embodiment, the clamping plate 216 is made of rubber.

[0039] In this embodiment, the clamping plate 216 is designed as a rubber structure, which brings multiple advantages in the measurement of the pitch and thickness of the bellows. First, the rubber material has excellent elasticity and flexibility, and can closely fit the complex curved surface of the inner wall of the bellows. Even when the bellows has slight deformation or irregular shape, it can ensure good contact and stable clamping effect, thereby improving the accuracy and reliability of the measurement. Secondly, the rubber clamping plate 216 can provide uniform distribution pressure during the clamping process, effectively avoiding local overpressure or damage to the surface of the bellows, and protecting the integrity of the object being measured. In addition, the rubber material The material also has a certain shock-absorbing and buffering effect, which can reduce the interference of external environmental factors such as vibration and impact on the measurement process, and improve the stability and accuracy of the measurement. Furthermore, the rubber clamping plate 216 is easy to clean and maintain, and has good corrosion resistance, and can adapt to a variety of working environments and medium conditions. Finally, rubber materials usually have good anti-slip properties, which helps to maintain the stable position of the bellows during the measurement process and prevent it from sliding or shifting. In summary, the rubber structure clamping plate 216 performs well in improving measurement accuracy, protecting the object being measured, reducing interference, and enhancing operational convenience.

[0040] Working principle: When using the device, the user can insert the bellows to be measured into the inner side of the annular structure 1, and place the inner wall of the bellows between the first measuring plate 26 and the second measuring plate 27. At this time, the user can start the telescopic rod 22, and the length of the telescopic rod 22 increases, which will push the fixed ring 23 to move vertically upward. While the fixed ring 23 moves upward, it will push the sliding block 25 outward through the rotating rod 24, thereby driving the first measuring plate 26 on the upper surface of the sliding block 25 to move outward, and then the bellows can be clamped between the first measuring plate 26 and the second measuring plate 27. At this time, the scale plate 29 can observe and measure the thickness of the bellows in real time. At the same time, the user can rotate the rotating handle 212, thereby driving the first rotating arm 21 3 rotates, and at the same time drives the second rotating arm 214 to rotate. When the second rotating arm 214 rotates, it pulls the third rotating arm 217, and then the sliding rod 215 is pulled by the third rotating arm 217 to move inside the fixed frame 211, and the bellows can be limited by the clamping plate 216. When the user needs to measure the pitch of the bellows, the user only needs to adjust the bellows to a horizontal state and place one side of the bellows between the first measuring plate 26 and the second measuring plate 27 to measure the pitch. Through multiple independent measuring units, each unit can independently and simultaneously measure different positions of the bellows, which can not only greatly improve the measurement efficiency, but also ensure the consistency of the measurement data at different positions of the entire bellows. , through the clamping main device of the slide bar 215, it can automatically adjust to adapt to bellows of different diameters and wall thicknesses. This adaptive clamping mechanism ensures stable contact with the inner wall of the bellows during the measurement process, reducing measurement errors caused by improper human operation. Through the self-locking design of the first rotating arm 213 and the second rotating arm 214, it automatically locks after completing the clamping action, ensuring that the bellows remains stable and motionless during the measurement process. This not only improves the stability of the measurement, but also avoids measurement errors caused by vibration or external force interference. The clamping plate 216 designed in a fan-shaped structure brings many significant advantages in the measurement of bellows pitch and thickness. First, the fan-shaped structure can better fit the curved surface of the inner wall of the bellows, especially when the bellows has complex waveforms or large When the diameter changes, this design can ensure that the contact area between the clamping plate 216 and the inner wall of the bellows is larger and more uniform, thereby improving the stability and accuracy of the measurement. Secondly, the fan-shaped clamping plate 216 can gradually apply force during the clamping process, and gradually wrap the bellows in a fan-shaped manner, effectively reducing the deformation or damage of the bellows that may be caused by the sudden application of clamping force. In addition, the fan-shaped design also facilitates the realization of multi-stage or adjustable clamping force to adapt to bellows of different materials, wall thicknesses and diameters, further enhancing the versatility and flexibility of the clamping plate 216. Finally, the fan-shaped clamping plate 216 is also more compact and beautiful in appearance, which helps to reduce the volume and weight of the entire measuring device and facilitates installation, movement and maintenance. Therefore,The fan-shaped clamping plate 216 is an important innovation for improving the measurement accuracy, efficiency and safety of bellows. Designing the clamping plate 216 into a rubber structure brings multiple advantages in the measurement of bellows pitch and thickness. First, the rubber material has excellent elasticity and flexibility, and can fit closely to the complex curved surface of the inner wall of the bellows. Even when the bellows has slight deformation or irregular shape, it can ensure good contact and stable clamping effect, thereby improving the accuracy and reliability of measurement. Secondly, the rubber clamping plate 216 can provide uniformly distributed pressure during the clamping process, effectively avoiding local overpressure or damage to the surface of the bellows, and protecting the The integrity of the measured object. Furthermore, the rubber material also has a certain shock-absorbing and cushioning effect, which can reduce interference with the measurement process caused by external environmental factors such as vibration and impact, thereby improving measurement stability and accuracy. Furthermore, the rubber clamping plate 216 is easy to clean and maintain, and has good corrosion resistance, which can adapt to a variety of working environments and media conditions. Finally, the rubber material generally has good anti-slip properties, which helps to maintain the stable position of the bellows during the measurement process and prevent it from sliding or shifting. In summary, the rubber structure of the clamping plate 216 performs well in improving measurement accuracy, protecting the measured object, reducing interference, and enhancing operational convenience.
