[0034] It should be noted that, without conflict, the features in the embodiments of this utility model and in different embodiments can be combined with each other.

[0035] Through careful and in-depth research, the inventor of this case provides a solution to the problems existing in the prior art. This utility model provides a device for measuring the height of a rivet protrusion of a riveted product, including: a fixed component, the fixed component having a first connecting piece; a moving component, the moving component having a second connecting piece and a replaceable profiling block connected to each other, the profiling block being connected to a side of the second connecting piece facing away from the first connecting piece, the profiling block having a measurement through-hole for the rivet protrusion of the riveted product to be measured to enter; a guiding elastic component, the guiding elastic component being fixed to the first connecting piece and providing a biasing force to the second connecting piece along a first direction to press the profiling block against the surface of the riveted product; a measuring component, the measuring component having a fixed part and a telescopic measuring part, the fixed part being fixedly connected to the first connecting piece, and the telescopic measuring part telescoping along a direction parallel to the first direction based on the second connecting piece to enter the measurement through-hole and abut against the upper surface of the rivet protrusion. The device for measuring the height of a rivet protrusion of the riveted product of this utility model changes the measurement of the static data of the height of the rivet protrusion of the riveted product to be measured to the measurement of dynamic data through the cooperation of the profiling block and the telescopic measuring part, and can improve the measurement accuracy of the height of the rivet protrusion in combination with the telescopic measuring part, reducing the quality risk of unqualified riveted products; the device can also improve the measurement efficiency of the height of the rivet protrusion through the measuring component.

[0036] As Figure 1 shown, this utility model provides a device for measuring the height of a rivet protrusion 51 of a riveted product 50, including: a fixed component 10, a moving component 20, a guiding elastic component 30 and a measuring component 40.

[0037] Specifically, the fixing component 10 has a first connecting member 11. The first connecting member 11 is used to fixedly connect the moving component 20, the guiding elastic component 30, and the measuring component 40, and remain relatively stationary during the measurement process.

[0038] Specifically, the moving component 20 has a second connecting member 21 and a replaceable profiling block 22 that are connected to each other. The profiling block 22 is connected to the side of the second connecting member 21 facing away from the first connecting member 11. The profiling block 22 has a measuring through-hole 221 for the rivet protrusion 51 of the riveted product 50 to be measured to enter. Further, the second connecting member 21 is used to fixedly connect other components of the moving component 20. The shape of the profiling block 22 can be designed into different shapes according to different riveted products 50 to be measured, and match the riveted products 50 to be measured, so that the rivet protrusion 51 can completely enter the measuring through-hole 221 during measurement, eliminating the measurement error caused by the riveted product 50 not being placed in place during the measurement process, and accurately measuring the height of the rivet protrusion 51.

[0039] Specifically, the guiding elastic component 30 is fixed to the first connecting member 11 and provides a biasing force along the first direction X to the second connecting member 21, pressing the profiling block 22 against the surface of the riveted product 50. The guiding elastic component 30 can eliminate the non-contact stress during the measurement process, ensure that the measuring profiling block 22 can better fit the riveted product 50, and thus make the measurement result more accurate.

[0040] Specifically, the measuring component 40 has a fixing portion 41 and a telescopic measuring portion 42. The fixing portion 41 is fixedly connected to the first connecting member 11, and the telescopic measuring portion 42 expands and contracts along the second connecting member 21 parallel to the first direction X to enter the measuring through-hole 221 and abut against the upper surface of the rivet protrusion 51. The telescopic measuring portion 42 can change the measurement of the static data of the height of the rivet protrusion 51 of the riveted product 50 to be measured into dynamic data measurement, which can improve the measurement accuracy and measurement efficiency of the height of the rivet protrusion 51.

[0041] Continue to refer to Figure 1 , in some embodiments, the profiling block 22 is in surface contact with the riveted product 50, so that the rivet protrusion 51 can completely enter the measuring through-hole 221 during measurement, eliminating the measurement error caused by the riveted product 50 not being placed in place during the measurement process, and accurately measuring the height of the rivet protrusion 51.

[0042] Such as Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, there are two sets of fixed components 10, moving components 20, and measuring components 40 that are symmetrically arranged. Each set of fixed components 10, moving components 20, and measuring components 40 can independently complete the measurement of the height of the rivet protrusion 51 of a riveting product 50, improving the measurement efficiency. In addition, the shapes of the profiling blocks 22 of each set of moving components 20 can be the same or different, which are used to measure two identical riveting products 50 simultaneously, or to measure different riveting products 50. This can improve the measurement efficiency and the versatility of the device at the same time.

[0043] Continue to refer to Figure 2 , in some embodiments, the fixed component 10 further has a slide rail 12. The slide rail 12 extends along the first direction X and is fixedly connected to the first connecting member 11. The moving component 20 further has a slider 23. The slider 23 is fixedly connected to the second connecting member 21 and sleeved on the slide rail 12. The second connecting member 21 moves along the first direction X through the cooperation of the slide rail 12 and the slider 23. The cooperation of the slide rail 12 and the slider 23 can facilitate the relative movement of the fixed component 10 and the moving component 20, and further change the measurement of the static data of the height of the rivet protrusion 51 of the riveting product 50 to be measured into dynamic data measurement, so as to improve the measurement accuracy.

[0044] Continue to refer to Figure 2 , in some embodiments, the fixed component 10 further has a limiting block 13. The limiting block 13 is fixedly connected to the first end of the first connecting member 11. The first end of the slide rail 12 is connected to the limiting block 13, and the second end of the slide rail 12 is connected to the second end of the first connecting member 11 to limit the slider 23. The setting of the limiting block 13 and the slide rail 12 makes the relative movement of the fixed component 10 and the moving component 20 restricted within a certain range, which can avoid measurement errors and improve the measurement accuracy.

[0045] Continue to refer to Figure 2 , in some embodiments, the guiding elastic component 30 has a bushing group 31 and a damping spring 32. The bushing group 31 extends along the first direction X. The bushing group 31 passes through and is fixed to the second end of the first connecting member 11. The second connecting member 21 is sleeved on the bushing group 31 to realize the movement of the second connecting member 21 relative to the first connecting member 11. The damping spring 32 is sleeved on the bushing group 31 and is located between the first connecting member 11 and the second connecting member 21. The damping spring 32 has a state of compression and elongation based on the movement stroke of the second connecting member 21 along the first direction X. The damping spring 32 can eliminate the non-contact stress during the measurement, ensure that the profiling block 22 for measurement can better fit the riveting product 50, and thus make the measurement result more accurate.

[0046] Continue to refer to Figure 2 and Figure 3, in some embodiments, the first connecting member 11 is L-shaped. The first end of the first connecting member 11 extends along the first direction X, and the second end of the first connecting member 11 extends in a direction perpendicular to the first direction X. The second connecting member 21 is L-shaped. The first end of the second connecting member 21 extends along the first direction X and is sleeved on the bushing group 31, and the second end of the second connecting member 21 extends in a direction perpendicular to the first direction X. The profiling block 22 is fixedly connected to the second end of the second connecting member 21. The shapes and positional relationships of the above-mentioned first connecting member 11 and second connecting member 21 can facilitate the movement of the second connecting member 21 relative to the first connecting member 11 along the first direction X, and further facilitate the conversion of the height of the rivet protrusion 51 into the movement height of the telescopic measuring portion 42 along the first direction X, so as to facilitate measurement and improve the measurement accuracy and efficiency. In addition, the shapes of the first connecting member 11 and the second connecting member 21 are generally similar and are generally centrosymmetric. In other embodiments, the first connecting member 11 and the second connecting member 21 may also adopt other shapes and positional relationships, and the present application does not limit this.

[0047] Continuing to refer to Figure 2 , Figure 3 and Figure 4 , in some embodiments, the fixing assembly 10 further has a fixing block 14. The fixing block 14 is located on the side of the first connecting member 11 close to the measuring assembly 40. The fixing block 14 is fixedly connected to the first connecting member 11, and the fixing block 14 is detachably connected to the fixing portion 41 of the measuring assembly 40. The fixing block 14 can ensure that the fixing portion 41 of the measuring assembly 40 remains stationary relative to the first connecting member 11 during the measurement process, so that the height of the rivet protrusion 51 is completely converted into the movement height of the telescopic measuring portion 42 along the first direction X, improving the measurement accuracy.

[0048] Continuing to refer to Figure 2 , in some embodiments, the measuring assembly 40 further has a cable 43 and an optical fiber amplifier. The fixing portion 41 and the optical fiber amplifier are electrically connected through the cable 43. The optical fiber amplifier can accurately measure the movement height of the telescopic measuring portion 42 along the first direction X, so as to accurately measure the height of the rivet protrusion 51 and improve the measurement accuracy.

[0049] Continuing to refer to Figure 2 , Figure 3 and Figure 4 , in some embodiments, the fixing assembly 10 further has a mounting base plate 15, and the first connecting member 11 is fixedly connected to the mounting base plate 15. The mounting base plate 15 can ensure the relative static state of the fixing assembly 10 during the measurement process, thereby reducing the measurement error and improving the measurement accuracy.

[0050] It should be noted that, except for the specifically defined connections or fixing methods of each part of the present invention, they can be set to be screwed, riveted, clamped or welded, etc. according to the specific application situation.

[0051] In summary, for the rivet protrusion height measuring device of the riveted product of the present utility model, through the cooperation of the profiling block and the telescopic measuring part, the measurement of the static data of the height of the rivet protrusion of the riveted product to be measured is changed to the measurement of dynamic data. Combining with the telescopic measuring part can improve the measurement accuracy of the rivet protrusion height and reduce the quality risk of unqualified riveted products; through the measuring assembly, the device can also improve the measurement efficiency of the rivet protrusion height.

[0052] The above content is a further detailed description of the present utility model in combination with specific optional implementation manners, and it cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or replacements can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
