Detailed implementation manners

[0023] The following further describes in detail the specific implementation manners of the present utility model by describing embodiments with reference to the accompanying drawings, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solutions of the present invention and facilitate its implementation.

[0024] As Figures 1 to 5 shown, the three-coordinate detection and positioning device for an automotive body-in-white includes a base plate 1, a column 2 is provided on the base plate 1, a connecting plate 3 is provided at the top of the column 2, a first connecting block 4, a second connecting block 5 and a pin seat 6 are sequentially arranged on the connecting plate 3 from bottom to top, and a positioning pin 7 is provided on the pin seat 6.

[0025] In the above structure, the base plate 1 is used to be fixed on the three-coordinate measuring platform 14, the column 2 raises the positioning components of the device to a height convenient for operation by the staff, and the connection is connected to the column 2 by bolts, facilitating the installation and disassembly of the positioning components; through the sequential arrangement of the base plate 1, the column 2, the connecting plate 3, the connecting block, the pin seat 6 and the positioning pin 7 from bottom to top, compared with the existing mechanism, the structure is greatly simplified and the weight is reduced, thereby avoiding the problems of difficult handling and inconvenient operation during the process of the measuring personnel switching vehicle models. In terms of installation, the connections between the components are stable, do not interfere with each other, and are easy to install and disassemble.

[0026] As Figure 3 shown, bolt connection holes 15 are provided on the first connecting block 4, the second connecting block 5 and the pin seat 6; the first connecting block 4, the second connecting block 5 and the pin seat 6 are all of L-shaped structures. The adjacent parts of the above components are connected by bolts, and the component structure is regular, facilitating connection and achieving a detachable installation effect. Since the first connecting block 4, the second connecting block 5 and the pin seat 6 are all of L-shaped structures, the planar contact between adjacent parts is reliable, the bolt installation positions do not interfere with each other, and at the same time, the bolt connection directions of adjacent parts form a 90° turn, and adjustment gaskets are provided between the components. The gap is adjusted by adding or subtracting precision gaskets or replacing gaskets of different thicknesses to achieve the purpose of adjusting the precision, so as to meet the precision adjustment requirements in the three-coordinate directions.

[0027] As Figure 3 and Figure 4As shown, the first connecting block 4, the second connecting block 5, and the pin seat 6 are all L-shaped structures. A first adjusting gasket 8 is provided between the connecting plate 3 and the first connecting block 4, a second adjusting gasket 9 is provided between the first connecting block 4 and the second connecting block 5, and a third adjusting gasket 10 is provided between the second connecting block 5 and the pin seat 6. The first adjusting gasket 8 is arranged with a gap between the connecting plate 3 and the first connecting block 4 for adjusting the Z-direction accuracy of the positioning pin 7. The second adjusting gasket 9 is arranged with a gap between the first connecting block 4 and the second connecting block 5 for adjusting the X-direction accuracy of the positioning pin 7. The third adjusting gasket 10 is arranged with a gap between the pin seat 6 and the second connecting block 5 for adjusting the Y-direction accuracy of the positioning pin 7.

[0028] As Figure 3 and Figure 4 shown, a positioning platform 11 is provided outside the positioning pin 7, and the positioning platform 11 is a cylindrical structure. The positioning pin 7 is set as a stepped pin. The top end of the positioning pin 7 is inserted into the body positioning hole for positioning the body in the X and Y directions. The stepped surface at the upper end of the positioning platform 11 supports the body for positioning the body in the Z direction. The three coordinate directions of the white body are all positioned, ensuring the accuracy of the white body measurement.

[0029] As Figure 4 shown, a first positioning step 12 is provided at the bottom of the positioning platform 11, and a second positioning step 13 is provided at the top end of the pin seat 6. The end portions of the first positioning step 12 and the second positioning step 13 are in contact. Through the surface contact action of a pair of positioning steps between the positioning platform 11 and the pin seat 6, the levelness of the positioning platform 11 and the verticality of the axis of the positioning pin 7 are maintained, further ensuring the accuracy of the white body measurement.

[0030] As Figure 3 shown, positioning holes 16 are provided between the bolt connection holes 15, and both the bolt connection holes 15 and the positioning holes 16 are arranged in pairs. The provision of the positioning holes 16 can prevent the components from rotating due to the large torque generated when tightening the bolts, improving the convenience of assembly. The arrangement of multiple bolt connection holes 15 and positioning holes 16 can improve the connection reliability and positioning accuracy.

[0031] As Figure 3 shown, the top end of the positioning pin 7 is a conical structure. Designing the insertion end of the positioning pin 7 as a cone can reduce the difficulty of aligning the positioning pin 7 with the body positioning hole.

[0032] As Figure 1 shown, both the bottom plate 1 and the connecting plate 3 are square, and the column 2 is a square tube structure. The square bottom plate 1 is convenient for aligning with the coordinate measuring platform 14. The column 2 adopts a square tube structure, which can reduce its weight and facilitate the transfer and handling by personnel.

[0033] As Figure 2 and Figure 5As shown in the figure, a three-coordinate measuring platform 14 is provided at the bottom of the bottom plate 1. A first fixing hole 17 is provided on the bottom plate 1, and second fixing holes 18 are evenly distributed on the three-coordinate measuring platform 14. In order to fix the white body detection and positioning device, the first fixing hole 17 corresponds to the second fixing hole 18. The bottom plate 1 and the three-coordinate measuring platform 14 are connected by pins and bolts. This device can be installed at multiple positions on the three-coordinate measuring platform 14 to meet the positioning requirements of different parts of the white body.

[0034] The usage method of this device is as follows: Move this device onto the three-coordinate measuring platform 14, and fix it through connection with bolts and pins. Use the three-coordinate measuring device to detect the accuracy of the positioning pin 7 and adjust it within the tolerance range required by the accuracy. Hoist the white body above this device, align the body positioning holes with the positioning pins 7. After the body measurement is completed, hoist the body away from this device, remove the pins and bolts connecting the bottom plate 1 and the measuring platform, and move this device away from the three-coordinate measuring platform 14 to start the detection of the next vehicle model in a cycle.

[0035] This three-coordinate detection and positioning device for the automotive white body simplifies the complex structure of the traditional white body detection and positioning device, reduces the weight, facilitates the handling process of the measurement personnel, and reduces the labor intensity of the measurement personnel; the device has a reasonable structure design, can meet the accuracy adjustment requirements, and can improve the accuracy of white body measurement; the components in the device are conveniently connected, the connection effect between the components is reliable, the bolt positions do not interfere with each other, the structure is simple, and the manufacturing cost is low.

[0036] The above has made an exemplary description of the present invention in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention; or without improvement, the above concept and technical solution of the present invention are directly applied to other occasions, they are all within the protection scope of the present invention.
