Abstract
Description

[0002] There is currently an end cap structure that includes an end cap, a ring seat, and a conical wall located between the end cap and the ring seat. This end cap structure requires multiple tests, including the height of the top wall of the ring seat, the height of the top wall of the end cap, and the height difference between the top walls of the ring seat and the top walls of the end cap.
[0003] Traditional testing typically employs manual methods or a semi-manual approach using a linear displacement measuring mechanism. This process requires two lifting and lowering displacement drives at the measuring end, along with radial displacement adjustment, resulting in a long measurement cycle and a high risk of displacement failure.
[0004] In addition, there are various specifications for the height of the ring seat of this type of structural component, which results in a lot of changes in the reference surface on which it is mounted. Traditional carriers are difficult to meet the requirements for reference surface adjustment and cannot achieve adaptive matching between the reference surface and the measuring end. This results in complex reference alignment for each measurement, which is very labor-intensive and time-consuming. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.
[0024] This utility model provides a coaxial dual-position contact detection device, such as Figures 1 to 6 As shown, the end cap structure 100 is used for testing. The end cap structure 100 includes an end cap 110 with a top surface wall 111, an annular seat 120 with an annular surface wall 121, and a conical wall 130 located between the end cap and the annular seat.
[0025] During testing, it is required to measure the height of the top wall 111 relative to the bottom wall and the height of the toroidal wall relative to the bottom wall. At the same time, it is also necessary to measure the relative height between the top wall 111 and the toroidal wall 121. Traditional testing benchmarks are difficult to determine, and using multiple tests will cause large errors.
[0026] This case is as follows Figures 1 to 6 As shown, it includes a carrier 1 and a measuring mechanism 2 located on top of the carrier 1.
[0027] The carrier 1 is equipped with a carrier 3 that has horizontal linear displacement, and the carrier 3 is equipped with an end cap platform 4 for supporting the end cap structure.
[0028] The measuring mechanism 2 includes a linkage lifting slider 5 with lifting displacement. The linkage lifting slider 5 is provided with a first measuring device 6 and a second measuring device 7. The first measuring device 6 is provided with a first floating measuring end 60 for floating contact with the top wall 111, and the second measuring device 7 is provided with a second floating measuring end 70 for floating contact with the annular wall.
[0029] Detailed implementation process and principle explanation: During measurement, the carrier 3 is first removed from the measuring mechanism 2. At this time, the end cap structure 100 is loaded and placed on the end cap platform 4. Then, the carrier 3 moves to the bottom of the measuring mechanism 2.
[0030] At this time, the linkage lifting slider 5 moves downward, causing the first measuring device 6 and the second measuring device 7 to move downward in tandem. The first floating measuring end 60 abuts against the top wall 111, and the second floating measuring end 70 floats against the annular wall 121, thus achieving synchronous measurement of the annular wall 121 and the top wall 111. At the same time, since the first measuring device 6 and the second measuring device 7 are linked, the measurement difference between their floating ends is the measurement height difference, thus achieving efficient detection.
[0031] In one specific embodiment, the linkage lifting slider 5 is provided with a linkage contact mechanism 50 for contacting the end cap structure.
[0032] The linkage contact mechanism 50 includes a guide base 51, a movable abutment body 52 with lifting and lowering displacement disposed on the guide base, and a measuring pin 53 with lifting and lowering displacement disposed within the movable abutment body 52. The movable abutment body 52 includes an annular abutment end 521 for engaging with the annular wall and an annular outer edge 522 located between the guide base and the second floating measuring end. The measuring pin 53 has a pin abutment end 531 for engaging with the top wall and a pin top end 532 opposite to the first floating measuring end. The measuring pin is provided with a limiting ring rib 533 located at the top of the movable abutment body.
[0033] Detailed implementation process and principle explanation: When not in contact, the movable contact body 52 and the measuring pin 53 are in a free-falling state, and are limited by the annular outer edge 522 and the limiting ring rib 533, respectively.
[0034] During measurement, the linkage lifting slider 5 descends until the annular abutment end 521 abuts against the annular wall and the pin abutment end 531 abuts against the top wall. As it continues to descend, the reverse force causes the movable abutment body 52 and the measuring pin 53 to rise. The outer edge of the annular shape 522 exerts pressure on the second floating measuring end, thereby measuring the height of the annular wall. Meanwhile, the top end 532 of the pin abuts against the first floating measuring end to measure the height of the top wall. Through the transmission cooperation between the movable abutment body 52 and the measuring pin 53, the requirement for surface contact measurement cooperation can be met, and the measurement accuracy is significantly improved.
[0035] In one specific embodiment, the movable abutment 52 is provided with a guide pin 520 that penetrates the annular outer edge.
[0036] The guide pin 520 enables sliding guidance, providing precise guidance for the lifting and lowering displacement of the movable contact body 52, making the measurement of the annular wall more reliable. Because the second floating measuring end is a point, its guiding accuracy ensures the horizontal accuracy of the top surface of the annular outer edge 522, making the point contact measurement reliable and stable.
[0037] In one specific embodiment, the measuring mechanism 2 includes a frame body 20, a linkage lifting slider is slidably connected to the frame body, and the frame body is provided with a lifting drive source 200 that is connected to the linkage lifting slider.
[0038] The lifting and guiding of the linkage lifting slider is achieved through the main frame 20, and a lifting drive source 200 is installed to drive its lifting and lowering. The lifting drive source can be a linearly driven cylinder or a servo and lead screw transmission mechanism. As long as the power structure that can drive the lifting and lowering of the linkage lifting slider is within the protection scope of this case.
[0039] In one specific embodiment, the end cap platform 4 is provided with a reference block 40 for reference to a reference plane; the linkage lifting slider 5 has a reference abutment part 500 for cooperating with the reference block.
[0040] Specifically, the reference abutment 500 and the linkage lifting slider 5 are in a hard-positioning engagement, meaning the descent stroke of the linkage lifting slider 5 is set with a threshold. This threshold stroke ensures that the first and second floating measuring ends are triggered. After hard positioning, a positioning reference is obtained after contact. This positioning reference is the horizontal plane where the bottom wall of the workpiece is located. At this time, the first and second floating measuring ends are pressed by their respective transmission structures to generate floating displacement, thereby obtaining the measurement value. This transmission structure is the movable abutment 52 and the measuring pin 53.
[0041] In one specific embodiment, the end cap platform 4 is detachably mounted on the carrier 3.
[0042] The assembly and disassembly of the end cover platform 4 can meet the requirements for model changeover, as well as the requirements for reference correction and replacement of the reference block 40. Assembly and disassembly are convenient.
[0043] In one specific embodiment, the end cap platform 4 is provided with a detection sensor 8 for monitoring the detection position of the end cap platform and a material detection sensor 9 for detecting the end cap structure.
[0044] Specifically, the linear displacement accuracy of carrier 3 is ensured by the horizontal guide rail, which guarantees the linear accuracy of its horizontal linear displacement. This is existing technology and will not be elaborated further. In this case, the material detection sensor 9 is used to detect the material on the end cap platform 4. Only when the material is detected can the linear displacement and detection operation be triggered. The detection sensor 8 is used to detect the positional accuracy of the detection position on the end cap platform 4, satisfying the vertical relative positional accuracy with the measuring mechanism 2.
[0045] As described above, this invention enables coaxial dual-position contact detection of the end cap structure, simultaneously meeting the requirements for loading / unloading and switching between detection positions, resulting in efficient and smooth detection operations. The design of the abutment-transfer structure, which aligns with the detection items, ensures proper contact with the floating ends of the first and second measuring instruments, guaranteeing measurement accuracy. The inclusion of a reference block for reference limit control enables reference stroke limit control, significantly improving relative measurement accuracy.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
