[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances. Example

[0038] The utility model provides a composite material roof cover inspection tool, please refer to Figure 1 and Figure 2 , including a base frame 1; the base frame 1 is provided with at least one coordinate origin 2, the coordinate origin 2 is aligned with the coordinates of the entire vehicle, and is used to simulate the actual assembly state of the composite material roof cover; the base frame 1 is provided with at least one positioning hole 101, the positioning hole 101 corresponds to the position of the positioning column of the composite material roof cover, when the composite material roof cover is placed on the base frame 1, the positioning column is correspondingly inserted into the positioning hole 101; the base frame 1 is also provided with a plurality of reference detection standard blocks 3, the plurality of reference detection standard blocks 3 surround The outer edge of the roof cover is used to simulate the assembly relationship between the composite material roof cover and the counterpart; the base frame 1 is also provided with a plurality of sets of slip detection mechanisms 4, which are arranged on the four sides of the base frame 1, and each set of the slip detection mechanisms 4 is respectively installed with a dial indicator for detecting the horizontal contour data of the composite material roof cover; the base frame 1 is also provided with a plurality of sets of Z-direction detection mechanisms 5, which are arranged in the slip detection mechanisms 4 for detecting the Z-direction contour data of the composite material roof cover.

[0039] Specifically, there are four coordinate origins 2, which are located at the four corners of the base frame 1, and each coordinate origin 2 is equipped with a coordinate information card. At the same time, the coordinate origin 2 is also the reference for three-coordinate detection, which is convenient for calibrating the reference detection block 3 and using three coordinates for product data collection.

[0040] Specifically, the reference detection standard block 3 is processed according to the counterpart of the composite material roof cover, and the reference detection standard block 3 is installed at a designated position according to the coordinate information provided by the coordinate origin 2 .

[0041] For further information, please also refer to Figure 3 The plurality of reference detection standard blocks 3 are spaced around the outer edge of the roof cover, and the gap detection positions are numbered. The gap detection position identification numbers are used to specify the detection sequence of the gap values ​​and to perform statistics and analysis on the gap value detection data. The gaps between the reference detection standard blocks 3 facilitate the removal or placement of the roof cover on the inspection tool, reduce the contact with the paint surface, and better protect the paint surface.

[0042] Among them, there are two positioning holes 101, which are distributed at both ends of the diagonal of the base frame 1, and the positioning holes 101 are located in the gap of the reference detection standard block 3, which is convenient for observing whether the composite material roof cover positioning columns are inserted into the positioning holes 101. The positioning columns on the inner surface of the roof cover can ensure the relative position of the roof cover on the tooling, as well as the consistency of the detection data and the whole vehicle installation and the consistency of the roof cover position each time it is detected.

[0043] Specifically, there are six groups of the slip detection mechanism 4, one group is arranged on each wide side of the base frame 1, and two groups are arranged on each long side, and a guide rail 401 is arranged at the bottom of each group of the slip detection mechanism 4. The slip detection mechanism 4 moves horizontally along the guide rail 401, thereby realizing the expansion or contraction of the inspection tooling.

[0044] For further information, please also refer to Figure 4 and Figure 5 The sliding detection mechanism 4 includes a sliding plate 402, a plurality of detection bearing blocks 403 and a sliding handle 404. The sliding plate 402 and the detection bearing blocks 403 installed at intervals on the sliding plate 402 are pushed by the sliding handle 404 to move horizontally along the guide rail 401, and a dial indicator passes through a first detection hole 405 on the detection bearing block 403 to detect the contour of the composite roof cover.

[0045] In actual inspection, the inspection bearing block 403 and the contour inspection site number are allocated according to the measuring point and the inspection height of the vehicle roof. The measuring site number can not only specify the contour inspection sequence, but also facilitate the statistics and analysis of the contour inspection data.

[0046] In addition, a limit plate is also arranged on the moving track of the sliding plate 402, and an expansion limit hole 406 and a closing limit hole 407 are respectively provided at both ends of the limit plate; when the sliding handle 404 is pulled upward and the sliding plate 402 is pushed to move to the position of the expansion limit hole 406, the sliding detection mechanism 4 is in the expansion state, and conversely, when the sliding handle 404 is pulled upward and the sliding plate 402 is pushed to move to the position of the closing limit hole 407, the sliding detection mechanism 4 is in the closing state.

[0047] The sliding handle 404 in the present invention is an anti-mistake handle, which needs to be pulled up before the sliding plate 402 can be moved, and the two limit holes correspond to the two states of the sliding detection mechanism 4 respectively. Only when the sliding plate 402 moves into place, the sliding handle 404 can be inserted into the limit hole.

[0048] Specifically, Figure 6 and Figure 7As shown, the Z-direction detection mechanism 5 includes a detection block 501 and a probe 502 . The probe 502 is installed in a probe hole of the detection block 501 . The Z-direction contour data of the composite material roof cover is detected by the probe 502 .

[0049] Further, such as Figure 8 As shown, the Z-direction detection mechanism 5 is also configured with a calibration mechanism, which includes an external dial indicator 6 and a calibration block 7. The calibration platform 701 of the calibration block 7 is placed on the detection block 501, and the ejector pin 702 is inserted into the ejector pin hole 503 of the detection block 501. The zero point position of the probe 502 is calibrated by the value of the external dial indicator 6.

[0050] In the present invention, all Z-direction detection mechanisms 5 share the same calibration mechanism for calibration, so that all Z-direction detection mechanisms 5 detect the same height.

[0051] Four moving wheels 8 and supporting feet 9 are installed at the bottom of the base frame 1 for moving the inspection tooling, two of which are universal wheels and the other two are fixed wheels, which ensure that the inspection tooling can be turned and moved and that the inspection tooling is not too flexible and difficult to operate; an overhead layer 11 is set up in the base frame 1 through square tubes 10 to facilitate the transfer of the inspection tooling by a forklift.

[0052] To ensure the accuracy of the test, the gauge needs to be calibrated before use. The three-coordinate coordinate system is used to perform a dot test on the gauge. The three-coordinate coordinate reference is the coordinate origin and coordinate information plate on the tooling. The gauge can be used after it is calibrated and tested.

[0053] When in use, move the inspection tool to the designated workshop (inspection temperature: 20±2℃, inspection humidity 40%-60%, and perform workshop flatness inspection according to the standard, for example: if the bottom plate of this set of inspection tool exceeds 1500mm, it must be leveled before use, and the flatness is 0.05 / 1000mm) and fix it, pull up the sliding handle 404 of the sliding detection mechanism 4, and withdraw all sliding detection mechanisms 4 outward along the guide rail 401. Use the calibration block 7 to calibrate each Z-direction detection mechanism 5 one by one, and zero the corresponding external dial indicator during calibration. Align the positioning column on the lower surface of the composite roof cover with the positioning hole 101 and place it on the inspection tool. After it is placed in place, record the reading of the external dial indicator 6 and the Z-direction value of the Z-direction detection mechanism 5. Then clamp the sliding detection mechanism 4 inward to the detection state, take out the dial indicator from the dial indicator storage box, and place the dial indicator into the dial indicator reference hole for calibration and zeroing. The first detection holes 405 on the slip detection mechanism 4 are detected and recorded one by one in the order of their numbers to obtain the contour data of the composite roof cover. After the dot detection with the dial indicator, a check go / no-go gauge is used according to the actual gap value to detect and record the gap value between the edge of the part and the tooling.

[0054] If more precise data of part or the whole is needed, use a forklift to place the tooling on the three-coordinate inspection platform, pull up the sliding handle 404 of the sliding inspection mechanism 4, withdraw all sliding inspection mechanisms 4 outward along the guide rail 401, use the coordinate origin 2 of the inspection tooling to zero the three coordinates, and after zeroing, perform three-coordinate marking and analysis on the part or the whole as needed, and output a three-coordinate report of precise measurement.

[0055] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
