Description

Technical Field

[0001] The utility model belongs to the technical field of sealing ring size detection and relates to a sealing ring size measuring device. Background Art

[0002] As a crucial component in industrial products, seals are widely used in hydraulic and pneumatic systems, as well as numerous mechanical devices requiring sealing performance. Their primary function is to prevent fluid leakage, ensuring stable operation and efficient performance of the equipment. In these demanding applications, the dimensional accuracy of the seal is directly related to the sealing performance and overall reliability of the equipment. Therefore, accurate measurement of the seal's dimensions after shaping is particularly important.

[0003] However, the measurement methods currently used in the field of sealing ring quality inspection have significant shortcomings. Traditional measuring tools, such as calipers, are primarily used to measure the inner and outer diameters and cross-sectional dimensions of sealing rings. While simple and easy to use, this method suffers from low inspection efficiency and, due to human error, large errors in judgment. Furthermore, sealing rings are typically made of flexible materials, such as rubber and plastic, which undergo significant deformation when subjected to measurement forces. This deformation, caused by the measurement force, is not only difficult to avoid but also has a significant impact on the measurement results, leading to increased measurement errors and failing to meet the high-precision requirements of mechanical sealing components.

[0035] The present invention is described in further detail below with reference to the accompanying drawings:

[0036] See also Figure 1-Figure 5 The utility model provides a sealing ring shaping size measuring device, including a detection device 1 and a fixing device 3; the detection device 1 includes: a slide rail seat 11; a lead screw 12 and a slider 13 are provided on the slide rail seat 11, a first connecting plate 14 and a positioning plate 16 are provided on the slider 13, the first connecting plate 14 is provided with a linear laser measuring instrument 15, and the output end of the first motor 17 is fixedly connected to the lead screw 12; the detection device 1 is provided with a positioning device 2, and the positioning device 2 includes: an aluminum groove 24; the aluminum groove 24 is provided on the top of the slide rail seat 11, and a first positioning sensor 21 and a second positioning sensor 2 are provided on the aluminum groove 24. 2 and a third positioning sensor 23; the fixing device 3 includes: a second motor 31; the second motor 31 is arranged on the second connecting plate 32, and the output end of the second motor 31 is fixedly connected to the left side of the fixing fixture 33, the fixing fixture 33 is used to clamp the sealing ring fixing device 34, and the sealing ring fixing device 34 is equipped with a first sealing ring 341, a second sealing ring 342, a third sealing ring 343 and a fourth sealing ring 344, and a rolling bearing 36 and a spring 37 are provided at the right end of the fixing fixture 33, and the rolling bearing 36 and the spring 37 are arranged between the top cover 35 and the bottom cover 38, and the top cover 35 and the base 38 are fixedly connected.

[0037] When performing the sealing ring shaping size inspection, the user clamps the sealing ring fixing device 34 in the middle position of the fixing fixture 33 to complete the clamping and fixing, and then starts the second motor 31; the second motor 31 controls the fixing fixture 33 to rotate, and the fixing fixture 33 drives the sealing ring fixing device 34 to rotate; then the first motor 17 is started, and the first motor 17 controls the screw 12 to rotate. The screw 12 rotates to make the slider 13 start to slide along the axial direction of the screw 12, and the slider 13 drives the first connecting plate 14, the line laser measuring instrument 15 and the positioning plate 16 fixed above to move synchronously; when the positioning plate 16 moves to the first fixed When the positioning plate 16 moves to the second positioning sensor 21, the line laser measuring instrument starts to collect the sealing ring size data. When the positioning plate 16 moves to the second positioning sensor 22, the sealing ring size data installed in the middle position of the sealing ring fixing device 34 is obtained. When the positioning plate 16 moves to the third positioning sensor 23, the line laser measuring instrument 15 ends the measurement, and one measurement is completed at this time; then the first motor 17 is controlled to rotate in the opposite direction to drive the slider 13 back to the starting position to facilitate subsequent multiple size data measurements. After the detection is completed, the second motor 31 is turned off, and the sealing ring fixing device 34 clamped between the fixing clamps 33 is removed.

[0038] Specifically, in order to ensure the stability of the fixing clamp 33 clamping the sealing ring fixing device 34, the right side of the fixing clamp 33 and the sealing ring fixing device 34, one end of the fixing clamp 33 is a convex structure, and the other end is provided with a groove; one end of the sealing ring fixing device 34 is provided with a groove, and the other end is provided with a convex structure; when clamping, the convex structure at one end of the fixing clamp 33 is tightly connected with the groove at one end of the sealing ring fixing device 34; the groove at the other end of the fixing clamp 33 is tightly connected with the convex structure at the other end of the sealing ring fixing device 34; in this state, the contact area between the sealing ring fixing device 34 and the fixing clamp 33 is the largest, which ensures the stability of the fixing clamp 33 clamping the sealing ring fixing device 34.

[0039] Specifically, the measuring range of the line laser measuring instrument 15 is 35±5 mm, so the line laser measuring instrument 15 can simultaneously scan an area of a certain width. As long as the scanning area of the line laser measuring instrument 15 can include the sealing ring that needs to be measured, the measurement can be completed. Therefore, the positioning accuracy of the measurement position is not too high.

[0040] Specifically, the process of measuring the sealing ring size does not require high positioning accuracy of the measurement position of the linear laser measuring instrument 15, so the positioning using the positioning sensor can also be modified to manual control, that is, the positioning device 2 can also be a physical positioning designed on the slide rail seat, and the control scheme can be flexibly adjusted as needed during the actual process.

[0041] In one embodiment of the present invention, four levels of sealing rings are installed on the sealing ring fixing device 34, namely the first sealing ring 341, the second sealing ring 342, the third sealing ring 343 and the fourth sealing ring 344. If other working conditions require dimensional measurement of more sealing rings, the structure of the sealing ring fixing device 34 can be flexibly modified as needed during the actual process to assemble more sealing rings to complete the measurement.

[0042] In one embodiment of the present invention, the process of removing the sealing ring fixing device 34 is as follows: first, the right side part of the fixing clamp 33 is pulled horizontally to the right, and the spring 37 connected thereto will cause the fixing clamp 33 to loosen its clamping of the sealing ring fixing device 34. Therefore, the fixing clamp 33 can also clamp sealing ring fixing devices 34 of different lengths, thereby improving the practicality of the fixing device.

[0043] The utility model relates to a sealing ring size measuring device that integrates a line laser measuring instrument, which is capable of providing high-precision measurement data. The combination of the lead screw drive and the slider sliding mechanism ensures stability and accuracy during the measurement process, making the measurement results more reliable. The first motor drives the lead screw to rotate, driving the slider and the positioning plate thereon and the line laser measuring instrument to move precisely along the slide rail seat, thereby realizing the automation of the measurement process. At the same time, the second motor drives the sealing ring fixture in the fixing fixture to rotate, facilitating comprehensive and multi-angle measurement of the sealing ring, reducing errors and labor intensity of manual operation. The device can easily adjust the measurement position through the design of the slide rail seat and the lead screw to meet the measurement needs of sealing rings of different sizes. In addition, the adjustability of the fixing fixture also enhances the versatility of the device, and it can clamp sealing ring fixtures of various specifications and shapes.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
