Description

Technical Field

[0001] The present application relates to the technical field of auxiliary positioning and assembly tooling for automobile body parts, and in particular to a positioning tooling. Background Art

[0002] In the whole vehicle assembly process of automobile manufacturing, key parts of automobile appearance, such as headlights, front bumper masks and front grilles, all rely on the basic structure of the front frame of the vehicle body for direct or indirect precise fixation. The front frame plays a crucial role in positioning the reference. Any assembly deviation will inevitably be transmitted to the installation position of subsequent parts, which may not only lead to the failure of smooth assembly of parts and increase the difficulty of adjustment, but also cause damage to parts, thereby damaging the appearance coordination of the front part and seriously affecting the overall assembly quality.

[0003] In order to ensure that the exterior parts can be accurately docked according to the design requirements and achieve the best visual effect, the front-end frame of the vehicle body must be precisely positioned. When performing the positioning and assembly of the front-end frame, it is also necessary to fully consider the natural deviations caused by the vehicle body manufacturing process. It cannot be simply based on theoretical data. It must be flexibly handled in combination with specific actual conditions to adapt to various potential change points and meet the requirements of positioning accuracy. Traditional front-end frame assembly usually relies on manual adjustment by operators. This method has deficiencies in positioning accuracy in the three-dimensional space of X, Y, and Z. It cannot effectively verify whether the workpiece has been accurately installed in place. Once the assembly deviation is detected, it often takes a lot of time and manpower to disassemble and readjust, which will undoubtedly increase additional costs.

[0004] Therefore, how to provide a positioning tool that can accurately position the front-end frame in the X, Y, and Z three-dimensional space is a problem that urgently needs to be solved. Utility Model Content

[0027] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0028] There will be a natural deviation between the mounting holes of the front-end frame 1 and the vehicle body 15 during manufacturing. During manufacturing, the mounting holes of the front-end frame 1 corresponding to the mounting holes of the vehicle body 15 are made larger than the required size. Therefore, during installation, the mounting holes of the front-end frame 1 and the mounting holes of the vehicle body 15 cannot be aligned based on theoretical data. The front-end frame 1 needs to be repositioned in X, Y, and Z directions so that each mounting hole of the front-end frame 1 is accurately aligned with the mounting hole of the vehicle body 15 so that the connecting bolts can be smoothly inserted into the mounting holes to complete the installation. In response to this problem, the inventor wants to design a positioning tool that is easy to use, labor-saving, and can accurately position the front-end frame 1. It should be noted that the parts to be positioned in this application include but are not limited to the front-end frame 1. The first direction A in this application is equivalent to the Y direction; the second direction B is equivalent to the X direction; and the third direction C is equivalent to the Z direction.

The two second support columns 24 are respectively against the two second positioning parts of the vehicle body 15, and the second positioning part can be specifically the front anti-collision beam. The first positioning part and the second positioning part are not specifically limited here, and can be selected according to actual needs. In addition, the first support column 23 and the second support column 24 can be set as cylinder telescopic columns to adjust the height of the first support column 23 and the second support column 24 according to actual needs. The first support column 23 and the second support column 24 can be specifically square columns or round columns. The first sliding assembly 13 includes a slide rail component and a slider. The first positioning assembly is installed at the bottom of the slide rail component. The first cross beam 21 is connected to the slide rail component through the slider. The length of the slide rail on the slide rail component extending along the first direction A can be set according to the actual size of the vehicle body 15. The length of the first positioning column 3 extending along the third direction C can be set according to production needs. The first positioning column 3 is used to be inserted into the positioning hole of the vehicle body 15. The two first positioning columns 3 slide along the first direction A through the first sliding assembly 13, and the sliding distance can be adjusted according to the distance between the two positioning holes of the vehicle body 15. The two clamping blocks 4 are relatively spaced along the first direction A on the side of the main frame 2 close to the first crossbeam 21. The spacing distance between the two clamping blocks 4 can be set according to the size of the front end frame 1. The two clamping blocks 4 are in contact with the surface to be clamped of the front end frame 1. The shape of the surface of the clamping block 4 in contact with the surface to be clamped of the front end frame 1 can be a square surface, a rectangular surface or a polygonal surface. The second sliding assembly 14 includes a slide rail component and a slider. The second positioning assembly is installed at the bottom of the slide rail component.

In addition, the slider can also be detachably connected to the first crossbeam 21 or the second crossbeam 22 through a connecting portion, and the first sliding assembly 13 and the second sliding assembly 14 can be replaced as needed. The connecting component here can specifically be a connecting block or a connecting plate, and the connection method can be a bolt connection or a snap connection.

[0031] The first aspect of the present application provides a positioning tool, which includes a main frame 2, two first positioning components, at least two clamping blocks 4 and two second positioning components. The main frame 2 is positioned in the X, Y and Z directions on the vehicle body 15 by means of the first positioning column 3 of the first positioning component, the first support column 23 arranged on the bottom surface of both ends of the first cross beam 21 and the second support column 24 arranged on the bottom surface of both ends of the second cross beam 22 to position the main frame 2, and then the front end frame 1 is positioned in the X, Y and Z directions on the vehicle body 15 by means of the second positioning component and the two clamping blocks 4 to accurately position the front end frame 1 on the vehicle body 15. When installing the front-end frame 1 using the positioning fixture, it is not necessary for the worker to manually adjust the position of the front-end frame 1 multiple times. During installation, the operator needs to pre-install the front-end frame 1 at the position to be positioned of the vehicle body 15, and then insert the first positioning columns 3 of the two first positioning components into the two positioning holes of the vehicle body 15 respectively to limit the position of the main frame 2 in the X and Y directions, and at the same time, the first support column 23 is pressed against the first positioning part of the vehicle body 15, and the second support column 24 is pressed against the second positioning part of the vehicle body 15 to limit the position of the main frame 2 in the Z direction. Then, the two second positioning columns 5 in the second positioning component are inserted into the two positioning holes of the front-end frame 1 to limit the position of the front-end frame 1 in the Y and Z directions, and the second positioning component is pushed along the second direction B so that the second positioning column 5 is close to the two clamping blocks 4 to clamp the front-end frame 1 between the second positioning column 5 and the clamping block 4 to limit the position of the front-end frame in the X direction, thereby completing the positioning of the front-end frame 1 in the X, Y, and Z directions. After the front end frame 1 is positioned, the second positioning assembly is pulled along the second direction B to move the second positioning assembly away from the clamping block 4 so that the second positioning column 5 is pulled out from the positioning hole of the front end frame 1, and then the first positioning column 3 is pulled out from the positioning hole of the vehicle body 15 to remove the positioning fixture. The positioning fixture can realize the adjustment of the front end frame 1 in the three directions of X, Y, and Z, which is convenient for matching the parts of the actual vehicle and ensures the matching quality of the front end.

[0032] In some embodiments, the positioning tool also includes a connecting member 6, which is rotatably set on the center line of the first direction A of the main frame 2, and includes: two connecting ends 61 relatively set along the second direction B; two pull rods 7, both of which extend along the first direction A and are relatively set along the first direction A, and the two ends of the two pull rods 7 that are close to each other correspond one-to-one with the two connecting ends 61 of the connecting member 6 and are rotatably connected, and the two ends of the two pull rods 7 that are far away from each other correspond one-to-one with the two first sliding components 13 and are connected.

[0033] Specifically, Figure 1-Figure 5As shown, in order to facilitate the centering of the main frame 2 relative to the vehicle body 15 along the first direction A, a connecting member 6 is also provided. The center point of the connecting member 6 can be set at the position of the center line of the first direction A of the main frame 2 by rotating the shaft. The shape of the connecting member 6 can be a circular plate, a rectangular plate, etc., and the specific shape of the connecting member 6 is not limited here, as long as the center point of the connecting member 6 is at an equal distance from the two connecting ends 61. The two tie rods 7 are of equal length, and the two ends of the two tie rods 7 that are close to each other correspond to the two connecting ends 61 of the connecting member 6 through the rotating shaft and are rotatably connected. The two ends of the two tie rods 7 that are far away from each other correspond to the two first sliding components 13 and are connected. The length of the tie rod 7 can be set according to actual needs, and the length of the tie rod 7 is not specifically limited here. When the operator pulls the first positioning column 3 of the first positioning assembly on the left side of the vehicle body 15 along the first direction A to slide toward the left side of the vehicle body 15 along the first direction A to insert it into the positioning hole of the vehicle body 15, the first positioning assembly on the left side drives the connecting member 6 to rotate relative to the main frame 2 through the pull rod 7 to drive the right pull rod 7 to slide to the right relative to the main frame 2 along the first direction A so that the first positioning column 3 in the first positioning assembly on the right side slides to the right along the first direction A to the positioning hole on the right. The connection member 6 and the pull rod 7 can be provided so that the position of the main frame 2 relative to the vehicle body 15 along the first direction A can be automatically centered.

[0034] In some embodiments, the connecting member 6 extends a limiting portion 62 along the second direction B, and limiting springs 8 are provided on both sides of the limiting portion 62 along the first direction A. The end of the limiting spring 8 facing away from the limiting portion 62 is fixed to the main frame 2, and the end of the limiting spring 8 close to the limiting portion 62 is pressed against the limiting portion 62.

[0035] Specifically, Figure 1 and Figure 3As shown, the connector 6 extends a limit portion 62 along the second direction B, and the length of the limit portion 62 can be set according to actual needs. The shape of the limit portion 62 can be rectangular, square or other shapes. Limit springs 8 are arranged on both sides of the limit portion 62. The two limit springs 8 have the same size and material, and the ends of the two limit springs 8 that are away from the limit portion 62 are respectively fixed to the main frame 2 through fixing components. The two limit springs 8 are both telescopic along the first direction A, and the ends of the limit springs 8 close to the limit portion 62 correspond to the two sides of the limit portion 62 one by one and relatively press against the two sides of the limit portion 62. Such a design requires the connector 6 to rotate to overcome the force of the limit spring 8 on the limit portion 62, and the connector 6 is prevented from rotating at will by setting the limit portion 62 and the limit spring 8. In addition, multiple limit springs 8 can be arranged at intervals on one side of the limit portion to make the connector 6 more stable. In addition, the connector is provided with a calibration pin 16, which can be arranged on a center line extending along the second direction B where the center point of the connector 6 is located, for checking whether the connector 6 has position deviation after being used for a period of time.

[0036] In some embodiments, each second positioning assembly further includes a positioning block 9, which is spaced apart from the second positioning column 5 along the first direction A, and a height of the positioning block 9 extending along the second direction B is higher than a height of the fixed end 51 of the second positioning column 5 extending along the second direction B.

[0037] Specifically, Figure 1 and Figure 2 As shown, in order to prevent the second positioning column 5 from being subjected to long-term stress due to long-term positioning of the front frame 1, each second positioning assembly further includes a positioning block 9, and the positioning block 9 may be in any shape, such as a rectangular block, a column, etc. The height of the positioning block 9 along the second direction B is higher than the height of the fixed end 51 of the second positioning column 5 extending along the second direction B so as to abut against the front frame 1 and cooperate with the clamping block 4 to limit the position of the front frame 1 in the second direction B, i.e., the position in the X direction.

[0038] In some embodiments, each clamping block 4 is detachably connected to the main frame 2 .

[0039] Specifically, as shown in the figure, in order to make the distance between the clamping blocks 4 adapt to the size of the front end frame 1, each clamping block 4 can be movably connected to the main frame 2 through a bolt connector 6, and the operator can adjust the distance between the clamping blocks 4 according to the size of the front end frame 1 to be installed.

[0040] In some embodiments, a chamfered surface is provided on a side of the contact surface of each clamping block 4 facing the second cross beam 22 away from the main frame 2, and the chamfered surface forms an angle with the horizontal plane.

[0041] Specifically, Figure 1As shown, each clamping block 4 is provided with a chamfered surface (not shown in the figure) on the side of the fitting surface facing the second cross beam 22 away from the main frame 2. The shape of the chamfered surface can be any shape, such as a rectangular surface, a polygonal surface or other shapes. The angle between the chamfered surface and the horizontal plane can be set according to actual production needs, such as 30°, 50°, or 60°. The chamfered surface plays a guiding role when installing the positioning tool.

[0042] In some embodiments, the positioning tool also includes a connecting plate 10, which extends along the first direction A and whose two ends correspond to and are connected to the second positioning component one by one; a positioning pin 11, which extends along the third direction C and is movably plugged into the second cross beam 22; wherein the connecting plate 10 is provided with a plurality of sockets 101 arranged at intervals along the second direction B and corresponding to and adapted to the positioning pin 11.

[0043] Specifically, Figure 1 and Figure 3 As shown, in order to facilitate the simultaneous movement of the two second positioning components at both ends of the second beam 22 along the second direction B, the positioning fixture also includes a connecting plate 10, and the two ends of the connecting plate 10 correspond to and are connected to the second positioning components one by one. In addition, a handle can be provided on the side of the connecting plate 10 away from the second beam 22 to facilitate the operation of the operator. In order to relatively fix the second positioning component relative to the front end frame 1 and the main frame 2 after positioning the front end frame 1, a positioning pin 11 is also provided. The positioning pin 11 extends along the third direction C and is movably plugged into the second beam 22. The connecting plate 10 is provided with a plurality of sockets 101 corresponding to and adapted to the positioning pin 11 and arranged at intervals along the second direction B. When the connecting plate 10 is slid along the second direction B to clamp the front end frame 1 between the second positioning column 5 and the clamping block 4, the positioning pin 11 is inserted into the corresponding socket 101 to fix the position of the second positioning component to prevent the second positioning component from moving.

[0044] In some embodiments, a plurality of weight-reducing holes 12 are provided at intervals on the outer surface of the main frame 2 .

[0045] Specifically, Figure 1-Figure 5 As shown, in order to reduce the weight of the positioning tooling and save materials, a plurality of weight-reducing holes 12 are provided on the outer surface of the main frame 2, and a plurality of spaced-apart weight-reducing holes 12 may also be provided on the first crossbeam 21 and the second crossbeam 22 of the main frame 2. In addition, a plurality of spaced-apart weight-reducing holes 12 may also be provided on the pull rod 7 and the connecting plate 10. The size of the weight-reducing holes 12 may be set according to actual needs, and the distance between two adjacent weight-reducing holes 12 may also be set according to actual needs. No specific limitation is imposed on the number and size of the weight-reducing holes 12 herein.

[0046] In some embodiments, the diameter of each first positioning column 3 gradually shrinks from an end close to the main frame 2 to an end away from the main frame 2 .

[0047] Specifically, Figure 1-Figure 5 As shown, the first positioning column 3 gradually shrinks from one end close to the main frame 2 to the end away from the main frame 2, and the shrinkage degree can be set according to actual needs. Designing the first positioning column 3 to be a gradually shrinking structure can reduce the use of materials and thus achieve the purpose of lightweight. It has a guiding effect when the first positioning column 3 is inserted into the positioning hole of the vehicle body 15, and it also helps to adapt to parts to be assembled of different sizes or shapes, thereby improving the convenience and accuracy of the overall assembly.

[0048] In some embodiments, each first support column 23 is detachably connected to the first beam 21 and a gasket is provided between each first support column 23 and the first beam 21; each second support column 24 is detachably connected to the second beam 22 and a gasket is provided between each second support column 24 and the second beam 22.

[0049] Specifically, Figure 1-Figure 5 As shown, the top of the first support column 23 and the first cross beam 21 are connected by bolts or snaps, and a gasket is provided between the first support column 23 and the first cross beam 21. The height of the gasket can be set according to actual needs, or multiple gaskets can be provided between the first support column 23 and the first cross beam 21, and the height can be adjusted by increasing or decreasing the number of gaskets according to actual needs. The top of the second support column 24 and the second cross beam 22 are connected by bolts or snaps, and a gasket is provided between the second support column 24 and the second cross beam 22. The height of the gasket can be set according to actual needs, or multiple gaskets can be provided between the second support column 24 and the second cross beam 22, and the height can be adjusted by increasing or decreasing the number of gaskets according to actual needs. In addition, the gaskets provided between the first support column 23 and the first cross beam 21 and between the second support column 24 and the second cross beam 22 can also prevent the first support column 23 and the first cross beam 21 from directly contacting or the second support column 24 and the second cross beam 22 from directly contacting and causing wear. The gasket is usually made of a wear-resistant, pressure-resistant and elastic material, such as metal, rubber or plastic. It can be filled in the gap between the first support column 23 and the first cross beam 21 or the second support column 24 and the second cross beam 22 to play the role of buffering, shock absorption and fine-tuning the angle. In addition, a support block can be set at the bottom of the first support column 23 and the second support column 24 close to the vehicle body 15. The support block can be made of rubber to prevent the first support column 23 and the second support column 24 from wearing the vehicle body 15 when they are in contact with the vehicle body 15.

[0050] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
