Among them, the Z axis represents the up-down direction, the positive direction of the Z axis represents the upper, and the negative direction of the Z axis represents the lower. It should be noted that the aforementioned Z axis represents the meaning is only for the convenience of describing the utility model and simplifying the description, and is not indicative or suggestive of the device or element indicated must have a specific orientation, structure and operation in a specific orientation, therefore, it cannot be understood as a limitation on the utility model.

[0029] As Figures 1-2As shown, the utility model discloses a kind of measuring tool, including tool body 1, first positioning structure 11 and profiling slot 12 are equipped on the tool body 1, profiling slot 12 is through setting along the thickness direction of the tool body 1, the tool body 1 is used to be installed on relevant part 4 by first positioning structure 11, to make the one end surface of the tool body 1 along thickness direction with the surface of relevant part 4 opposite, profiling slot 12 is used to detect whether the position of adhesive strip 41 on relevant part 4 meets process requirement.

[0030] Specifically, tool body 1 can be long thin plate, for the convenience of description, below all take tool body 1 horizontal setting as example to explain.The thickness direction of tool body 1 is Z direction, the length direction of tool body 1 is X direction, and the width direction is Y direction, one side of tool body 1 along Z axis negative direction can be equipped with first positioning structure 11, tool body 1 is placed above relevant part 4, and can be positioned and assembled with relevant part 4 by first positioning structure 11.

[0031] Tool body 1 is equipped with profiling slot 12 through along Z direction, profiling slot 12 can be linear type or curved type slot extending along X direction, and the design shape of profiling slot 12 is consistent with the shape of theoretical adhesive strip 41.

[0032] In the embodiment, by controlling the relative position relationship of first positioning structure 11 and profiling slot 12 on tool body 1, after tool body 1 is positioned and installed on relevant part 4 such as vehicle body by first positioning structure 11, adhesive strip 41 on relevant part 4 is theoretically just in profiling slot 12, in the actual measurement process, whether adhesive strip 41 position meets process requirement is judged by observing whether adhesive strip 41 on relevant part 4 falls in profiling slot 12 of tool body 1, if adhesive strip 41 all falls in profiling slot 12, then it is judged that adhesive strip 41 position meets process requirement, otherwise, it is judged that adhesive strip 41 position does not meet process requirement, to realize the quick and accurate judgment of whether adhesive strip 41 position meets process requirement.In the judgment of adhesive strip 41 position not meeting process requirement, it needs to be readjusted to glue track, at this time, mark pen such as marker pen can be used to draw glue track on relevant part 4 along the extension direction of profiling slot 12, and robot can glue according to the glue track.

[0033] As Figure 3 And Figure 5 As shown, optionally, the measuring tool further includes measuring ruler 2, profiling slot 12 is strip-shaped, the end surface of tool body 1 away from relevant part 4 along thickness direction is equipped with a plurality of second positioning structures, a plurality of second positioning structures are interval arranged along the extension direction of profiling slot 12, and the second positioning structure is used for positioning measuring ruler 2 arranged perpendicularly to profiling slot 12.

[0034] Here, the adhesive strip 41 is in a strip structure, and the profiled slot 12 is also in a strip shape, which can be linear or curved. The measuring ruler 2 can be a common steel ruler.

[0035] The measuring ruler 2 is used to measure the width of the adhesive strip 41 on the relevant part 4 from the side of the tool body 1 away from the relevant part 4 through the profiled slot 12. The second positioning structure is arranged on the side of the tool body 1 away from the relevant part 4, and can be used to position the measuring ruler 2. The second positioning structure can be a protruding structure, a recess structure, or a positioning mark arranged on the surface of the tool body 1.

[0036] When the profiled slot 12 and the adhesive strip 41 are linear, the measuring ruler 2 being perpendicular to the profiled slot 12 means that the straight line on which the measuring ruler 2 is arranged is perpendicular to the extension direction of the profiled slot 12, so as to ensure that the measuring ruler 2 can be measured at a set position along a direction perpendicular to the extension direction of the profiled slot 12, i.e., perpendicular to the length direction of the adhesive strip 41.

[0037] When the profiled slot 12 and the adhesive strip 41 are curved, the adhesive strip 41 falls into the profiled slot 12. Theoretically, the profiled slot 12 is curved and consistent with the curved shape of the adhesive strip 41. At this time, the measuring ruler 2 being perpendicular to the profiled slot 12 means that the measuring ruler 2 is arranged perpendicular to the tangent line passing through the measuring point of the adhesive strip 41. The second positioning structure positions the measuring ruler 2, so as to ensure that the measuring ruler 2 can accurately measure the width of the adhesive strip 41.

[0038] Optionally, the tool body 1 is provided with a mounting boss 13 on the end surface away from the relevant part 4 in the thickness direction. The mounting boss 13 is arranged in parallel with the profiled slot 12. At least one side of the profiled slot 12 is provided with the mounting boss 13. The second positioning structure includes a detection slot 131 arranged on the mounting boss 13. The measuring ruler 2 is used to pass through the detection slot 131 to be arranged above the profiled slot 12. The measuring ruler 2 is used to detect the width of the adhesive strip 41.

[0039] Specifically, the tooling body 1 has a mounting boss 13 on its end face away from the related part 4 along the thickness direction. That is, the tooling body 1 has a mounting boss 13 on its side along the positive Z-axis. The mounting boss 13 and the contouring groove 12 are arranged parallel to each other, and both can extend along the X-direction. At least one side of the contouring groove 12 has a mounting boss 13, including the following situations: there is one mounting boss 13, and one side of the contouring groove 12 has a mounting boss 13; or, there are two mounting bosses 13, and the two sides of the contouring groove 12 are respectively provided with mounting bosses 13. The mounting boss 13 has a plurality of detection grooves 131 spaced apart along its extension direction. The detection grooves 131 penetrate the mounting boss 13 along the Y-direction. The detection grooves 131 can be rectangular grooves, and their width can match or be slightly larger than the width of the measuring ruler 2.

[0040] During measurement, the measuring ruler 2 is inserted along the Y-axis into one of the detection slots 131 of the mounting boss 13. The measuring ruler 2 spans across the top of the contour slot 12. Using the measuring ruler 2, the width of the adhesive strip 41 within the contour slot 12 can be quickly and roughly measured. Then, the measuring ruler 2 is pulled out and inserted into the other detection slots 131 in sequence to obtain the width of the adhesive strip 41 at different measuring points, thus achieving a more accurate measurement of the adhesive strip 41's dimensions. Moreover, compared to directly measuring the width of the adhesive strip 41 using the measuring ruler 2, inserting the measuring ruler 2 into different detection slots 131 of the mounting boss 13 ensures the accuracy of the measuring direction of the measuring ruler 2 and the position of the measuring points on the adhesive strip 41, achieving a more accurate measurement of the width of the adhesive strip 41.

[0041] Optionally, the detection slot 131 has a guide slope on its wall to guide the insertion of the measuring ruler 2. One end of the detection slot 131 along the Y direction has a guide slope, allowing one end of the measuring ruler 2 to be smoothly inserted into the detection slot 131 along the guide slope, thus improving detection efficiency.

[0042] like Figure 3 , Figure 5 and Figure 6 As shown, optionally, the mounting boss 13 is also provided with a plurality of third positioning structures at intervals along its extension direction. The measuring fixture also includes a caliper 3, which includes a vernier 31 and a main scale 32. The third positioning structure is used to position the main scale 32, which is set perpendicular to the contour groove 12. The vernier 31 is movably disposed on the main scale 32 and is used to move along the main scale 32 to detect the width and position of the adhesive strip 41.

[0043] Specifically, the main ruler 32 can be a long structure extending along the Y direction, and the third positioning structure is arranged on the mounting boss 13 to position the main ruler 32, so that the cursor 31 can move along a direction perpendicular to the profiling slot 12 at a set position. The third positioning structure can be a protruding structure, a groove structure, or a positioning mark arranged on the surface of the mounting boss 13.

[0044] The main ruler 32 and the cursor 31 are both provided with scales, and the reading principle is similar to that of a vernier caliper. The cursor 31 includes a cursor body and a leg connected to the cursor body. The cursor body is arranged on the main ruler 32 and can move along the extension direction of the main ruler 32. The main ruler 32 is arranged above the profiling slot 12, that is, above the rubber strip 41. When the cursor 31 moves and the leg is aligned with the rubber strip 41, the position value of the cursor 31 is read, the measurement is more convenient, and the accuracy is higher.

[0045] The two end faces of the cursor body along the moving direction are respectively marked as a first reference face 311 and a second reference face 312. The cursor 31 is moved until the leg is aligned with one side of the rubber strip 41, the scale value m corresponding to the first reference face 311 is read, the cursor 31 is continuously moved until the leg is aligned with the other side of the rubber strip 41, and the scale value n corresponding to the second reference face 312 is read. The actual width of the rubber strip 41 is |m-n|, the actual center line position of the rubber strip 41 is (m+n) / 2, and the theoretical distance between the zero scale of the main ruler 32 and the center line of the rubber strip is a certain value a. The actual measured center line position value of the rubber strip 41 is compared with the theoretical value. If they are not equal, it indicates that the position of the rubber strip 41 deviates and the rubber coating track needs to be adjusted.

[0046] When the thickness of the cursor body is small, the first reference face 311 and the second reference face 312 can not be marked, and the reading of the scale line aligned by the cursor body can be directly read.

[0047] When the profiling slot 12 and the rubber strip 41 are straight lines, the perpendicularity of the main ruler 32 to the profiling slot 12 means that the straight line where the main ruler 32 is located is perpendicular to the extension direction of the profiling slot 12, so that the cursor 31 can move along a direction perpendicular to the extension direction of the profiling slot 12, that is, perpendicular to the length direction of the rubber strip 41, to be aligned with the two sides of the rubber strip 41 respectively, and measure the width of the rubber strip 41.

[0048] When the profiling slot 12 and the rubber strip 41 are curved, the rubber strip 41 falls into the profiling slot 12, and the profiling slot 12 is theoretically a curved shape consistent with the curved shape of the rubber strip 41. At this time, the perpendicularity of the main ruler 32 to the profiling slot 12 means that the main ruler 32 is perpendicular to the tangent line passing through the measuring point of the rubber strip 41. The third positioning structure positions the main ruler 32 to ensure that the cursor 31 can be aligned with the inside and outside of the curved part of the rubber strip 41 in sequence during the movement along the main ruler 32, so that the measured width of the rubber strip 41 is more accurate.

[0049] As Figure 3 and Figure 6 shown, optionally, the third positioning structure includes a third positioning hole 132 arranged on the mounting boss 13, and the caliper 3 further includes a positioning fitting structure 33, at least one end of the main ruler 32 is provided with the positioning fitting structure 33, the positioning fitting structure 33 is arranged one by one with the mounting boss 13, and the positioning fitting structure 33 is used for inserting the third positioning hole 132.

[0050] Specifically, the positioning fitting structure 33 can be formed separately from the main ruler 32, the positioning fitting structure 33 can be fixed on the main ruler 32 through a bolt, the positioning fitting structure 33 is provided with a scale side away from the main ruler 32, the positioning fitting structure 33 is arranged one by one with the mounting boss 13, and the mounting boss 13 can be provided with one or two, that is, the positioning fitting structure 33 can be provided with one or two. The mounting boss 13 is provided with a plurality of third positioning holes 132 along the extension direction of the mounting boss 13, that is, the X-axis direction, the third positioning hole 132 can penetrate the mounting boss 13 along the Z direction, and even in some cases, can penetrate the tool body 1 downward.

[0051] When measuring, the caliper 3 is inserted into one of the third positioning holes 132 of the mounting boss 13 through the positioning fitting structure 33, the main ruler 32 is transversely arranged above the profiling slot 12, the vernier 31 is moved, the width and position of the corresponding measuring point of the rubber strip 41 can be accurately measured, then the caliper 3 is pulled out, and the positioning fitting structure 33 of the caliper 3 is sequentially inserted into other third positioning holes 132 to respectively obtain the width and position of different measuring points of the rubber strip 41, so that more accurate measurement of the size and position of the rubber strip 41 is realized.

[0052] As Figure 3 shown, optionally, the third positioning structure and the second positioning structure are alternately arranged along the extension direction of the mounting boss 13. The third positioning structure is used for positioning the caliper 3, and the second positioning structure is used for positioning the measuring ruler 2, so that the measurement of the caliper 3 and the measuring ruler 2 can be independently carried out without interference, and the smoothness and efficiency of detection are ensured.

[0053] As Figure 3As shown, optionally, two mounting bosses 13 are arranged, and the two mounting bosses 13 are respectively located on the two sides of the profiling clamping groove 12, wherein a plurality of second positioning structures on one of the mounting bosses 13 are arranged one-to-one with a plurality of second positioning structures on the other mounting boss 13, and the corresponding second positioning structures on the two mounting bosses 13 are used for positioning the measuring ruler 2 together; and / or, a plurality of third positioning structures on one of the mounting bosses 13 are arranged one-to-one with a plurality of third positioning structures on the other mounting boss 13, and the corresponding third positioning structures on the two mounting bosses 13 are respectively used for positioning the two ends of the main ruler 32.

[0054] Taking the second positioning structure as the detection clamping groove 131 and the third positioning structure as the third positioning hole 132 as an example, the two mounting bosses 13 can be symmetrically arranged on the two sides of the profiling clamping groove 12. By arranging two mounting bosses 13 and arranging a plurality of detection clamping grooves 131 on one of the mounting bosses 13 one-to-one with a plurality of detection clamping grooves 131 on the other mounting boss 13, the measuring ruler 2 is inserted into the corresponding detection clamping grooves 131 on the two mounting bosses 13 at the same time, and the two detection clamping grooves 131 simultaneously exert a supporting force on the two ends of the measuring ruler 2, thereby ensuring the assembly stability of the measuring ruler 2 on the tool body 1 and preventing the measuring ruler 2 from shaking, which is beneficial to ensuring the accuracy of the measurement result.

[0055] By arranging two mounting bosses 13 and arranging a plurality of third positioning holes 132 on one of the mounting bosses 13 one-to-one with a plurality of third positioning holes 132 on the other mounting boss 13, the main ruler 32 of the caliper 3 is inserted into the corresponding third positioning holes 132 on the two mounting bosses 13 by using the positioning matching structures 33 at the two ends of the main ruler 32, and the two third positioning holes 132 simultaneously position the main ruler 32, thereby ensuring the assembly stability of the caliper 3 on the tool body 1 and preventing the caliper 3 from being misaligned, which is beneficial to ensuring the accuracy of the measurement result.
