Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle frame assembly, and particularly relates to a positioning tool for assembling and positioning the front / rear body frame. Background Art

[0002] When assembling the vehicle frame, a tooling is needed for positioning, and the accuracy of the tooling positioning will affect the assembly accuracy and quality of the vehicle frame. For the assembly of the cross beam or column corresponding to the body curved surface part in the vehicle frame, generally, a curved surface substrate matching the radian of the body curved surface part is arranged in the tooling, and the cross beam or column corresponding to the body curved surface part in the vehicle frame is positioned through the curved surface substrate. Therefore, the curved surface accuracy of the curved surface substrate will directly affect the positioning and bending accuracy of the cross beam or column. At present, the processing of the curved surface substrate is generally completed by a sheet metal worker through multiple processes such as hot forming, cold bending, knocking, and correction of the sheet. When the body curved surface part is a three-dimensional curved surface, for example, some vehicles have arcs on the side and top of the front or rear body of the vehicle, that is, the front or rear body of the vehicle is in the shape of a three-dimensional curved surface, that is, in the shape of a spherical surface or an irregular spherical surface, with arc changes in multiple directions, and the positions of the frame members at this position generally correspond to the front and rear glass of the vehicle. Therefore, the positioning accuracy requirement is high. However, when using the curved surface substrate for positioning, it is difficult to precisely control the arc changes in multiple directions during the processing of the curved surface substrate corresponding to the shape, resulting in problems such as large tooling processing difficulty, long cycle, and high production cost. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a positioning tool for assembling and positioning the front / rear body frame, which can ensure the positioning accuracy of the front / rear body frame assembly, reduce the processing difficulty of the positioning tooling, shorten the production cycle, and reduce the labor cost.

[0004] The content of the utility model includes L-shaped plates, vertical plates, connecting plate one, and connecting plate two. There are two vertical plates, and there are more than two L-shaped plates. The more than two L-shaped plates face the same direction and are spaced between the two vertical plates. The connecting plate one is in plug-in fit with the horizontal ends of the more than two L-shaped plates and the two vertical plates, and the connecting plate two is in plug-in fit with the vertical ends of the more than two L-shaped plates;

[0005] The tops of the two vertical plates are both arcs that bend downward from the end close to the vertical end of the L-shaped plate to the end close to the horizontal end of the L-shaped plate. The horizontal ends of the more than two L-shaped plates are all provided with positioning grooves one, and the vertical ends are all provided with positioning grooves two. The positions of the positioning grooves one on the more than two L-shaped plates and the ends of the two vertical plates close to the horizontal end of the L-shaped plate are all located on the arc surface corresponding to the radian of the front / rear end of the body, and the positions of the positioning grooves two on the more than two L-shaped plates and the ends of the two vertical plates close to the vertical end of the L-shaped plate are all located on the arc surface corresponding to the radian of the top of the front / rear body.

[0006] Furthermore, one end of the top of the two vertical plates close to the vertical end of the L-shaped plate is connected to the connecting plate 2, and a positioning groove 3 is provided on the connecting plate 2 at a position corresponding to the position of the one end of the top of the two vertical plates close to the vertical end of the L-shaped plate.

[0007] Furthermore, it also includes two lateral positioning plates, which are plugged into the connecting plate and are correspondingly located on the sides of the two vertical plates, and the tops of the two lateral positioning plates are higher than the tops of the adjacent vertical plates.

[0008] Furthermore, the two lateral positioning plates are arranged parallel to and spaced apart from the adjacent vertical plates.

[0009] Furthermore, the tops of the two lateral positioning plates are arc-shaped with the same curvature as the tops of the adjacent vertical plates, and the two lateral positioning plates and the two vertical plates are hollowed out.

[0010] Furthermore, positioning grooves four are provided on the tops of the two vertical plates.

[0011] Furthermore, positioning grooves five are provided at one and two ends of the connecting plate.

[0012] Furthermore, it also includes a connecting plate three, which is arranged at the bottom of one side of the two or more L-shaped plates away from the positioning groove one, and positioning grooves six are arranged at both ends of the connecting plate three.

[0013] Furthermore, positioning groove seven is provided at the top of the vertical end of more than two L-shaped plates. Positioning groove seven is spaced apart from positioning groove two in the direction of the length of the vehicle body at the top of the vertical end of the L-shaped plate, and the positions of positioning groove seven on the more than two L-shaped plates are all located on the arc surface corresponding to the curvature of the top of the front / rear panel of the vehicle body.

[0014] Furthermore, it also includes a base, and the L-shaped plate, vertical plate, connecting plate 1 and connecting plate 2 are all arranged on the base.

[0015] The beneficial effects of the present invention are as follows: the arc-shaped frame components at the end positions of the front / rear enclosure of the vehicle body are positioned by a pair of positioning grooves on the horizontal ends of two or more L-shaped plates, and the arc-shaped frame components at the top positions of the front / rear enclosure of the vehicle body are positioned by a pair of positioning grooves on the vertical ends of two or more L-shaped plates, and the arc-shaped frame components located at the three-dimensional curved surface position between the end portions and the top of the front / rear enclosure of the vehicle body are positioned at the assembly position and the bending curvature thereof is positioned during the bending process by the top portions of the two vertical plates, thereby realizing the positioning of the assembly of the front / rear enclosure frame of the vehicle body, reducing the difficulty of assembling the positioning of the arc-shaped frame components located in the three-dimensional curved surface area between the end portions and the top of the front / rear enclosure of the vehicle body and ensuring the positioning accuracy.

[0016] Compared with the positioning tooling using a curved substrate, on the basis of realizing the positioning of the front / rear body frame assembly of a three-dimensional curved surface and ensuring the positioning accuracy, the processing accuracy control of the positioning tooling is more difficult, reducing the processing difficulty of the positioning tooling, shortening the production cycle and reducing the labor cost.

And the welding fixation after the plug-in fit only requires spot welding and local forging welding, avoiding welding deformation caused by too many welding areas, which is beneficial to improving the positioning accuracy of the front / rear body frame assembly.

[0023] Such as Figures 1 - 4As shown in the figure, the present utility model relates to a positioning tooling for assembling the front / rear body frame. The front / rear body of the vehicle refers to the front body or the rear body of the vehicle. The positioning tooling includes an L-shaped plate 1, a vertical plate 2, a first connecting plate 3, and a second connecting plate 4. There are two vertical plates 2, and there are more than two L-shaped plates 1. More than two L-shaped plates 1 are all located between the two vertical plates 2, and the more than two L-shaped plates 1 have the same orientation and are arranged at intervals along the direction of the line connecting the two vertical plates 2. The horizontally arranged end of the L-shaped plate 1 is its horizontal end, and the vertically arranged end is its vertical end. The first connecting plate 3 is inserted and matched with the horizontal ends of more than two L-shaped plates 1 and the two vertical plates 2, and the second connecting plate 4 is inserted and matched with the vertical ends of more than two L-shaped plates 1. The insertion and matching positions are fixed by welding. The insertion and matching specifically refer to the structural form of inserting and splicing through grooves or holes. For example, holes are opened at the vertical end or horizontal end of the L-shaped plate 1, and the first connecting plate 3 or the second connecting plate 4 is inserted into the holes at the corresponding positions to achieve the corresponding insertion and matching; or for another example, grooves are opened at the vertical end or horizontal end of the L-shaped plate 1, and the bottom of the first connecting plate 3 or the second connecting plate 4 is directly inserted into the corresponding grooves to achieve the corresponding insertion and matching, or grooves matching the positions and sizes of the grooves on the L-shaped plate 1 are also opened at the bottom of the first connecting plate 3 or the second connecting plate 4, and the corresponding insertion and matching are achieved through the insertion and matching between the grooves. The above-mentioned structures such as holes and grooves, and the shapes of the L-shaped plate 1, the vertical plate 2, the first connecting plate 3, and the second connecting plate 4 are pre-formed by laser cutting with corresponding equipment.

[0024] The tops of the two vertical plates 2 are both arc-shaped, and the arc-shaped is bent downward from the end close to the vertical end of the L-shaped plate 1 to the end close to the horizontal end of the L-shaped plate 1 at the tops of the two vertical plates 2. Positioning grooves 11 are provided at the horizontal ends of more than two L-shaped plates 1, and positioning grooves 12 are provided at the vertical ends. The positions of the positioning grooves 11 on the adjacent L-shaped plates 1 are different in the length direction of the horizontal end, and the positions of the positioning grooves 12 on the adjacent L-shaped plates 1 are different in the height direction of the vertical end. And the positions of the positioning grooves 11 on more than two L-shaped plates 1 and the end of the tops of the two vertical plates 2 close to the horizontal end of the L-shaped plate 1 are all located on the arc surface corresponding to the arc of the front / rear end of the vehicle body, and the positions of the positioning grooves 12 on more than two L-shaped plates 1 and the end of the tops of the two vertical plates 2 close to the vertical end of the L-shaped plate 1 are all located on the arc surface corresponding to the arc of the top of the front / rear of the vehicle body. Among them, the number of L-shaped plates 1 is preferably three. The distance between the positioning groove 11 on the middle L-shaped plate 1 and the vertical end of the L-shaped plate 1 is greater than the distance between the positioning groove 11 on the L-shaped plates 1 on both sides and the vertical end of the L-shaped plate 1. The height of the positioning groove 12 on the middle L-shaped plate 1 is higher than the height of the positioning grooves 12 on the L-shaped plates 1 on both sides. A rib plate is arranged at the connection between the vertical end and the horizontal end of the L-shaped plate 1 to increase the strength.

[0025] Based on the above settings, when assembling the front / rear body frame, the utility model positions the arc-shaped frame members at the end positions of the front / rear body through the positioning grooves 11 on the lateral ends of two or more L-shaped plates 1, and positions the arc-shaped frame members at the top positions of the front / rear body through the positioning grooves 12 on the vertical ends of two or more L-shaped plates 1. Moreover, the top parts of the two vertical plates 2 are used to position the assembly position of the arc-shaped frame members at the three-dimensional curved surface position between the end and the top of the front / rear body and to position the bending radian during the bending process, so as to realize the positioning of the front / rear body frame assembly, reduce the positioning difficulty of the arc-shaped frame members in the three-dimensional curved surface area between the end and the top of the front / rear body, and ensure the positioning accuracy.

[0026] The L-shaped plates 1, the vertical plates 2, the first connecting plates 3 and the second connecting plates 4 are arranged in an interpenetrating manner to jointly form an approximate grid-shaped tooling structure. The positioning tooling only needs to cut out plates with corresponding shapes and sizes according to the overall structural characteristics of the front / rear body frame and then assemble them, and the processing accuracy of the positioning tooling can be converted from manual control to mechanical equipment. Compared with the positioning tooling using a curved surface substrate, on the basis of realizing the positioning of the three-dimensional curved surface-shaped front / rear body frame assembly and ensuring the positioning accuracy, the utility model has a lower processing accuracy control difficulty for the positioning tooling, reduces the processing difficulty of the positioning tooling, shortens the production cycle and reduces the labor cost. The plug-in fit can not only increase the structural stability of the positioning tooling, reduce the deformation degree of the positioning tooling under long-term use, ensure the accuracy of the positioning tooling under long-term use, but also achieve good assembly error prevention and reduce the assembly difficulty of the positioning tooling. Moreover, the welding fixation after the plug-in fit only requires spot welding and local forging welding, which avoids welding deformation caused by excessive welding areas and is beneficial to improving the positioning accuracy of the front / rear body frame assembly.

[0027] One end of the top parts of the two vertical plates 2 close to the vertical ends of the L-shaped plates 1 is welded to the second connecting plates 4, and positioning grooves 41 are provided at positions corresponding to the one end of the top parts of the two vertical plates 2 close to the vertical ends of the L-shaped plates 1 on the second connecting plates 4. Based on this setting, while the second connecting plates 4 play a role in connecting the L-shaped plates 1 and the vertical plates 2 for structural strengthening, the positioning grooves 41 can also be used to accurately position one end of the arc-shaped frame members positioned by the vertical plates 2, which is convenient for the connection between the arc-shaped frame members positioned by the positioning grooves 12 of the L-shaped plates 1.

[0028] The present invention also includes two lateral positioning plates 5, which are plugged into and welded to the connecting plate 1 3. The two lateral positioning plates 5 are located on the sides of the two vertical plates 2, and the tops of the two lateral positioning plates 5 are higher than the tops of the adjacent vertical plates 2. The arrangement of the lateral positioning plates 5 can laterally position the arc-shaped frame member positioned by the vertical plates 2, ensuring that the arc-shaped frame member does not deviate laterally during assembly and bending, thereby ensuring the positioning accuracy of the arc-shaped frame member. Compared with the method of providing an arc-shaped positioning groove on the top of the vertical plate 2, this arrangement method is less difficult to process while meeting the requirements of use.

[0029] The two lateral positioning plates 5 and their adjacent vertical plates 2 are arranged parallel to each other with a spacing smaller than the width of the arc-shaped skeleton component positioned by the vertical plate 2, so that there is sufficient spacing between the adjacent lateral positioning plates 5 and the vertical plates 2 to support the arc-shaped skeleton component at that position.

[0030] In the present invention, it is preferred that the tops of the two lateral positioning plates 5 are arc-shaped with the same curvature as the tops of the adjacent vertical plates 2, and the two lateral positioning plates 5 and the two vertical plates 2 are hollowed out. On the basis of meeting the aforementioned positioning and support requirements, the materials used for the lateral positioning plates 5 and the vertical plates 2 are reduced, further reducing the cost of positioning tooling.

[0031] There are four positioning grooves 21 on the top of the two vertical plates 2, which are used to position the arc-shaped frame components on both sides of the front / rear of the vehicle body when the frame is assembled. There are two four positioning grooves 21 on the top of a single vertical plate 2.

[0032] The connecting plate 1 (3) is provided with a positioning groove 5 (31) at both ends. Based on this arrangement, the connecting plate 1 (3) not only connects the L-shaped plate 1, the vertical plate 2 and the lateral positioning plate 5 to strengthen the structure, but also uses the positioning groove 5 (31) to position the curved and extended portions of the front / rear end arc-shaped frame members of the vehicle body during the frame assembly. The number of connecting plates 1 (3) is determined by the size of the front / rear frame of the vehicle body and the strength requirements of the tooling. Figures 1 - 4 In the embodiment, there are two, and in other embodiments, there may be one or three or more.

[0033] The present invention also includes a connecting plate three 6, which is arranged at the bottom of one side of two or more L-shaped plates 1 away from the positioning groove one 11, and a positioning groove six 61 is provided at both ends of the connecting plate three 6. Based on this arrangement, the connecting plate three 6 not only connects several L-shaped plates 1 to strengthen the structure, but also can position the parts of the arc-shaped skeleton components at the front / rear end of the vehicle body that extend further to both sides through the positioning groove six 61 when the skeleton is assembled.

[0034] At the top of the vertical ends of two or more L-shaped plates 1, there is also a seventh positioning groove 13. The seventh positioning groove 13 is arranged at intervals with the second positioning groove 12 in the direction corresponding to the vehicle body length at the top of the vertical ends of the L-shaped plates 1, and the positions of the seventh positioning grooves 13 on adjacent L-shaped plates 1 are different in the height direction of the vertical ends. The positions of the seventh positioning grooves 13 on two or more said L-shaped plates 1 are all located on the arc surface corresponding to the top arc of the vehicle body front / rear enclosure. This seventh positioning groove 13 is used to position the assembly of another arc-shaped structural member along the vehicle body length direction at the front / rear top of the vehicle body. Since both the second positioning groove 12 and the seventh positioning groove 13 are arranged at the top of the vertical ends of the L-shaped plate 1, by setting the heights of the top of the vertical ends of adjacent L-shaped plates 1 to be different, the heights of the second positioning groove 12 and the seventh positioning groove 13 on adjacent L-shaped plates 1 can be made different.

[0035] The utility model further includes a base 7. The L-shaped plates 1, the vertical plates 2, the first connecting plates 3 and the second connecting plates 4 are all arranged on the base 7, and the setting method can be plugging or welding and fixing. The positioning tooling as a whole is supported by the base 7.

[0036] Figure 3 and Figure 4 The figure shows a schematic diagram of the positioning tooling of the utility model applied to the assembly of the front / rear enclosure skeleton of a vehicle body. The side and top of the front / rear enclosure of this vehicle have arcs, and the area between the front / rear ends and the top of the front / rear enclosure of the vehicle body is in a three-dimensional curved surface shape. Among them, in this vehicle: the arc-shaped structural member located at the front / rear ends of the vehicle body is the gantry frame column 100, the arc-shaped structural members located at the top of the front / rear enclosure of the vehicle body include the front windshield lower cross beam 200 and the through lamp lower cross beam 600, the arc-shaped structural member located in the three-dimensional curved surface area between the front / rear ends and the top of the front / rear enclosure of the vehicle body is the front windshield stop lip column 300, and the arc-shaped structural members located on the side of the front / rear enclosure of the vehicle body include the bracket upper cross beam 400 and the bracket lower cross beam 500. Since the positions corresponding to the gantry frame column 100, the front windshield lower cross beam 200, the bracket upper cross beam 400, the bracket lower cross beam 500 and the through lamp lower cross beam 600 on the front / rear enclosure of the vehicle body are one-way curved surfaces, the precision control of the gantry frame column 100, the front windshield lower cross beam 200, the bracket upper cross beam 400, the bracket lower cross beam 500 and the through lamp lower cross beam 600 is relatively low, and they can be pre-bent and formed and then assembled.

[0037] As Figure 3 and Figure 4As shown, during assembly, the middle part of the gantry frame column 100 is clamped into the first positioning groove 11 for positioning. Its two ends extend towards both sides of the front / rear body enclosures and are clamped into the fifth positioning groove 31 and the sixth positioning groove 61 for positioning. The front windshield lower crossbeam 200 is clamped into the second positioning groove 12 for positioning. The through-light lower crossbeam 600 is clamped into the sixth positioning groove 61 for positioning. And the two ends of the front windshield lower crossbeam 200 and the through-light lower crossbeam 600 extend downwards and are welded to the two ends of the gantry frame column 100 that extend towards both sides of the front / rear body enclosures. One end of the front windshield stop lip column 300 is clamped into the third positioning groove 41 and welded to the front windshield lower crossbeam 200. And the whole front windshield stop lip column 300 is gradually bent downwards in an arc along the top of the vertical plate 2 through corresponding processing, and the other end of the front windshield stop lip column 300 is welded to the gantry frame column 100, so as to control the position and bending accuracy of the front windshield stop lip column 300 in the three-dimensional curved surface area between the front / rear ends and the top of the body. One end of the upper crossbeam 400 of the bracket and the lower crossbeam 500 of the bracket are respectively clamped into two fourth positioning grooves 21 and welded to the front windshield stop lip column 300, and the other end is welded to the front windshield stop lip column 300. Thus, on the basis of realizing the assembly of the front body front / rear body enclosure skeleton of the vehicle and ensuring the assembly accuracy, the positioning difficulty and the bending accuracy control difficulty of the skeleton in the three-dimensional curved surface area between the front / rear ends and the top of the body are reduced, so as to ensure the skeleton positioning accuracy in this area part.
