Description

Technical Field

[0001] The present application relates to the field of detection technology, and in particular to a gap measurement tool. Background Art

[0002] The DTS (Dimensional Technical Specification) of a complete vehicle refers to the design requirements for the clearance and flushness between the various components of the interior and exterior of the vehicle. It is an important indicator of the manufacturing quality of the interior and exterior of the vehicle, and it is a reflection of the dimensional quality manufacturing level of the vehicle, and it is the customer's subjective evaluation of the product quality. DTS is a requirement for the matching relationship between parts, including the clearance and flushness of part matching, where the clearance refers to the width of the gap between two parts. During the automobile manufacturing process, when evaluating the DTS of the complete vehicle, a clearance gauge is needed to measure the clearance of part matching.

[0003] Due to the uniqueness of automobile styling design, when gap gauges are used to measure the gaps in some positions, the gaps cannot be measured due to insufficient internal space or too shallow gaps. The existing gap gauges cannot fully meet the needs of automobile gap measurement, affecting the test results. The measurement is inconsistent with the actual situation and cannot guide automobile engineers in the evaluation of the vehicle DTS and subsequent matching and adjustment work, resulting in low work efficiency. Utility Model Content

[0006] A gap measuring tool has a width direction and a length direction perpendicular to the width direction. The size of the gap measuring tool in the width direction is used to measure the gap. The gap measuring tool includes multiple splicing units, each of which has a large end and a small end. In the length direction, the size of the splicing unit in the width direction gradually increases from the small end to the large end. The small end of one splicing unit is detachably connected to the large end of another splicing unit, and the sum of the width ranges of the two splicing units spliced ​​together is greater than the width range of any one of them.

[0010] According to an embodiment of the present application, each splicing unit also has two side edges, the two side edges are located between the small end and the large end, and the angles between the two side edges and the length direction are both acute angles.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The gap gauge is used to measure the width of the gap, that is, the gap. The traditional gap gauge is usually an integrated tapered long ruler. When the depth of the gap is shallow, the gap cannot be measured. The reason is that, for example, when measuring the gap at part of the front door or rear door, the required tolerance band is 3.0-5.0mm. The existing integrated tapered gap gauge has a gap length of about 5.0mm from 0 to 3.0mm. That is to say, to measure a gap of 3.0mm width, the gap depth needs to be at least 5.0mm. However, the gap depth at part of the front door or rear door is less than 2.0mm. The gap in this part is too shallow to be measured.

[0035] In view of this, the present application provides a gap measurement tool that can be used for gap measurement of shallow gaps.

[0036] See also Figures 1 to 3 , Figure 1 is a three-dimensional schematic diagram of a first embodiment of the gap measurement tool provided by the present application, Figure 2 yes Figure 1 Schematic diagram of the gap measurement tooling. Figure 3 yes Figure 1 The front view of the gap measuring tool 10 shows that the gap measuring tool 10 has a width direction and a length direction perpendicular to the width direction. In the present application, for the convenience of describing the directions, the width direction is set to W and the length direction is set to L.

[0037] The dimension of the gap measuring tool 10 in the width direction W is used to measure the gap. During measurement, the gap measuring tool 10 can be inserted into the gap along the length direction L. When the two side surfaces of the gap measuring tool 10 in the width direction W abut against the two side walls of the gap, the dimension of the gap measuring tool 10 in the width direction W at the abutting point is the width dimension of the gap, that is, the gap.

[0038] The gap measuring tool 10 includes a plurality of splicing units 100, each of which has a large end 101 and a small end 102. In the length direction L, the size of the splicing unit 100 in the width direction W gradually increases from the small end 102 to the large end 101. The small end 102 of one splicing unit 100 is detachably connected to the large end 101 of another splicing unit 100, and the sum of the width ranges of the two splicing units 100 spliced ​​together is greater than the width range of any one of them.

[0039] The gap measuring tool of the present application improves the integrated structure of the traditional gap gauge into a segmented structure. The gap measuring tool 10 is composed of a plurality of splicing units 100. The number of splicing units 100 can be selected according to the depth of the gap. Figure 4 A schematic diagram showing a gap measurement tool 10 provided in the present application for measuring a deeper gap 20 is shown; Figure 5 The schematic diagram of the gap measuring tool 10 provided by the present application for measuring a shallow gap 20 is shown. Before measuring the gap, the size and environment of the gap 20 of the object to be measured can be identified first, so as to preliminarily determine the depth of the gap 20. The present application can be applied to the gap measurement of shallow gaps 20 as well as the gap measurement of deep gaps 20. When the gap 20 is deep, a large number of splicing units 100 can be selected to be spliced ​​into a long ruler, that is, used as a traditional gap ruler. When the gap 20 is shallow, a small number of splicing units 100 can be selected for splicing or a single splicing unit 100 can be directly used as a short ruler. When measuring, the gap measuring tool 10 is vertically inserted into the gap 20. When the two side edges of the gap measuring tool 10 in the width direction W are against the two side walls of the gap 20, the size of the gap measuring tool 10 in the width direction W at the abutment is the gap value of the gap 20.

[0040] In the present application, the meaning that the sum of the width ranges of two splicing units 100 spliced ​​to each other is greater than the width range of any one of them is that the width ranges of the two splicing units 100 are different, for example, the width ranges of the two splicing units 100 are 3-3.8mm and 4-5mm respectively; or the width ranges of the two splicing units 100 have overlapping parts, for example, the width ranges of the two splicing units 100 are 3-4.5mm and 4.5-5mm respectively; or the width ranges of the two splicing units 100 have only one common endpoint, for example, the width ranges of the two splicing units 100 are 3-4mm and 4-5mm respectively.

[0041] Since the gap measuring tool 10 in the present application is composed of multiple splicing units 100, if the width ranges of the two splicing units 100 spliced ​​together are the same or the width range of one of them falls within the width range of the other, the overall width range of the gap measuring tool 10 formed after the two splicing units 100 are spliced ​​together will still be the width range of a single splicing unit 100, which will make the splicing of the splicing units 100 meaningless. Therefore, the present application is configured so that the sum of the width ranges of the two splicing units 100 spliced ​​together is greater than the width range of any one of them, so that the gap measuring tool 10 formed after the two splicing units 100 are spliced ​​together can have a larger width range. Figures 1 to 5 It shows the situation that the width ranges of two splicing units 100 have only one common endpoint, and the dimension of the gap measuring tool 10 formed after the splicing units 100 are formed in the width direction W is a continuous interval along the length direction L.

[0042] Figures 1 to 5 In the illustrated embodiment, the number of the splicing units 100 is three. It is understandable that in other embodiments, the number of the splicing units 100 may be set to two, four, five or other numbers according to actual needs.

[0043] In the present application, in order to facilitate reading of the dimension of the gap measuring tool 10 in the width direction W, that is, to facilitate reading of the gap value, a scale number can be set on each splicing unit 100, so that after the gap measuring tool 10 is inserted into the gap 20, the gap value of the gap 20 can be obtained directly by reading the scale number.

[0044] See again Figure 1 and Figure 2 In one embodiment, the small end 102 of one splicing unit 100 is provided with a first connection part 110, and the large end 101 of the other splicing unit 100 is provided with a second connection part 120. The two splicing units 100 can be detachably connected by magnetic attraction between the first connection part 110 and the second connection part 120. In this embodiment, the detachable connection is achieved by magnetic attraction between the two splicing units 100, and the disassembly operation is more convenient and fast. It can be understood that in other embodiments, the two splicing units 100 can also be detachably connected by other methods such as bonding, snapping, etc., which are not limited to the magnetic attraction method in this embodiment.

[0045] Specifically, the first connection part 110 and the first connection part 110 may both be magnets, or one of them may be a magnet and the other may be made of a metal material that can be attracted by a magnet. The shapes and structures of the first connection part 110 and the first connection part 110 are not limited as long as they can fit together. However, considering that the gap measurement after the two splicing units 100 are spliced ​​is not affected by the first connection part 110 and the first connection part 110, it can be set that one of the first connection part 110 and the first connection part 110 is a protrusion and the other is a recessed part. Therefore, after the two splicing units 100 are spliced, the end face of the small end 102 of one of the splicing units 100 can fit with the end face of the large end 101 of the other splicing unit 100. The first connection part 110 and the first connection part 110 can also be other shapes. For example, the first connection part 110 is a magnetic surface provided on the small end 102 of one of the two splicing units 100, and the second connection part 120 is a magnetic surface provided on the large end 101 of the other splicing unit 100. The detachable connection of the two splicing units 100 can also be achieved by fitting the two magnetic surfaces.

[0046] In one embodiment, the small end 102 of one splicing unit 100 is provided with a first connection part 110, and the large end 101 of the other splicing unit 100 is provided with a second connection part 120, and the two splicing units 100 can be positioned relative to each other through the concave-convex fit between the first connection part 110 and the second connection part 120. In this embodiment, the two splicing units 100 are positioned relative to each other through the first connection part 110 and the second connection part 120, and the two splicing units 100 can be quickly spliced ​​into place when splicing. Specifically, one of the first connection part 110 and the second connection part 120 is a protruding part and the other is a recessed part, Figures 1 to 3 In the embodiment shown in FIG. 1 , the first connection portion 110 is a recessed portion that is recessed compared to the small end 102 of the splicing unit 100 , and the second connection portion 120 is a protruding portion that is protruding compared to the large end 101 of the splicing unit 100 .

[0047] In one embodiment, the small end 102 of one splicing unit 100 is provided with a first connecting portion 110, and the large end 101 of the other splicing unit 100 is provided with a second connecting portion 120. The two splicing units 100 can be detachably connected by magnetic attraction between the first connecting portion 110 and the second connecting portion 120, and the two splicing units 100 can be mutually positioned by the concave-convex fit between the first connecting portion 110 and the second connecting portion 120. In this embodiment, the fit between the first connecting portion 110 and the second connecting portion 120 can realize both the detachable connection between the two splicing units 100 and the mutual positioning between the two splicing units 100. Specifically, one of the first connecting portion 110 and the second connecting portion 120 is a protruding portion and the other is a recessed portion. Figures 1 to 3In the embodiment, the first connecting portion 110 is a recessed portion that is recessed compared to the small end 102 of the splicing unit 100, and the second connecting portion 120 is a protruding portion that is protruding compared to the large end 101 of the splicing unit 100. Each splicing unit 100 is made of a metal material that can be attracted by a magnet, such as an iron material (in order to reduce rust or corrosion of the iron material, the surface of each splicing unit 100 can be treated with anti-oxidation). The protruding portion is a magnet. Therefore, when two splicing units 100 are spliced ​​together, the two splicing units 100 can be quickly spliced ​​into place through the snap-fitting cooperation between the protruding portion and the recessed portion, and the magnetic attraction between the protruding portion and the recessed portion can achieve relative fixation between the two splicing units 100.

[0048] See again Figures 1 to 3 In one embodiment, each splicing unit 100 further has two side edges 103, the two side edges 103 are located between the small end 102 and the large end 101, and the angles between the two side edges 103 and the length direction L are both acute angles, that is, both side edges 103 of a single splicing unit 100 in this embodiment are both beveled edges. The angle between one of the two side edges 103 of a single splicing unit 100 and the length direction L is set to α, and the angle between the other side edge 103 and the length direction L is set to β, Figures 1 to 3 In the illustrated embodiment, the angles α between one side 103 of each of the three splicing units 100 and the length direction L are α1, α2 and α3, respectively, and the angles β between the other side 103 and the length direction L are β1, β2 and β3, respectively.

[0049] Each splicing unit 100 includes a large end 101, a small end 102, and two side edges 103 connected between the large end 101 and the small end 102, so that the plurality of splicing units 100 include a triangular splicing unit 100 and at least one trapezoidal splicing unit 100 ( Figures 1 to 3 As shown), the gap measuring tool 10 formed after each splicing unit 100 is spliced ​​together is also triangular; or, the multiple splicing units 100 include at least two trapezoidal splicing units 100, that is, each splicing unit 100 is trapezoidal, and the gap measuring tool 10 formed after each splicing unit 100 is spliced ​​together is also trapezoidal.

[0050] See again Figure 3 In one embodiment, the angles between the two sides 103 of a single splicing unit 100 and the length direction L are the same, that is, α and β of a single splicing unit 100 are equal, that is, the single splicing unit 100 is an isosceles triangle or an isosceles trapezoid. Figure 6 , Figure 6 It is a front view of the second embodiment of the gap measuring tool 10 provided in the present application. In this embodiment, α and β in a single splicing unit 100 may also be unequal.

[0051] See also Figure 7 , Figure 7 It is a front view of the third embodiment of the gap measuring tool 10 provided in the present application. In this embodiment, each splicing unit 100 also has two side edges 103, and the two side edges 103 are located between the small end 102 and the large end 101, wherein the angle between one side edge 103 and the length direction L is an acute angle, and the other side edge 103 is parallel to the length direction L, that is, in this embodiment, one side edge 103 of a single splicing unit 100 is a hypotenuse, and the other side edge 103 is a straight edge.

[0052] In the above embodiments, the sizes of the splicing units 100 in the length direction L are the same or different. Preferably, the sizes of the splicing units 100 in the length direction L are the same.

[0053] In one embodiment, after the two splicing units 100 are spliced ​​along the length direction L, the sides 103 of the two splicing units 100 are coplanar. Figures 1 to 7 The diagram shows a situation where the side edges 103 of the two splicing units 100 are coplanar after the two splicing units 100 are spliced ​​along the length direction L. In these embodiments, α1, α2 and α3 of each splicing unit 100 are equal, β1, β2 and β3 are equal, and the large end 101 of one splicing unit 100 and the small end 102 of the other splicing unit 100 in the adjacent splicing units 100 are the same in the width direction W, so that the size of the gap measuring tool 10 formed after the splicing of the splicing units 100 in the width direction W is a continuous interval along the length direction L.

[0054] In other embodiments, after the two splicing units 100 are spliced ​​along the length direction L, the side edges 103 of the two splicing units 100 may not be coplanar. There are three situations in which the side edges 103 are not coplanar after splicing: the first situation is that the large ends 101 and the small ends 102 of the two adjacent splicing units 100 have the same size in the width direction W, but the angles between the same side edges 103 of the two adjacent splicing units 100 and the length direction L are different ( Figure 8 The second case is that the angle between the same side 103 of two adjacent splicing units 100 and the length direction L is the same, but the dimensions of the large end 101 and the small end 102 of the two adjacent splicing units 100 in the width direction W are different ( Fig. 9 The third case is that the angles between the same side 103 of two adjacent splicing units 100 and the length direction L are different, and the sizes of the large end 101 and the small end 102 of the two adjacent splicing units 100 in the width direction W are also different ( Fig.10 shown).
