Description

Technical Field

[0001] The present application belongs to the technical field of vehicle parts production, and in particular, relates to a ceiling tooling structure. Background Art

[0002] The ceiling is an important part of the interior of the whole car. Its main function is to improve the decorativeness of the interior of the car. At the same time, the ceiling can also improve the heat insulation and thermal insulation effect from the outside of the car; reduce the noise inside the car, improve the sound absorption effect; and improve the comfort and safety of the passengers. Therefore, after the ceiling is produced, it is often necessary to use a tooling table to fix the front and rear parts of the ceiling so that the ceiling and the body can be assembled together later. However, due to the increasing demand for flexible production of multiple models on the same line (that is, the production of multiple models can be met under the same circumstances), if a tooling table that can only fix the ceiling of a single model is used, it will not only lead to a long development cycle and high manufacturing costs, but also affect production efficiency.

[0036] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0037] Reference below Figure 1 and Figure 2 The ceiling tooling structure provided in the embodiment of the present application is described, and the ceiling tooling structure includes a tooling platform 100 , a first positioning structure, a second positioning structure 300 , and a third positioning structure 400 .

[0038] The material of the tooling platform 100 includes but is not limited to stainless steel, aluminum alloy or titanium alloy, etc. The tooling platform 100 includes a plurality of vertical beams 110, a first horizontal frame and a second horizontal frame, that is, the first horizontal frame and the second horizontal frame are connected by a plurality of vertical beams 110 and are arranged at intervals in the vertical direction, and the first horizontal frame and the second horizontal frame are respectively formed by two first cross beams 120 and a plurality of second cross beams 130 connected to form a square frame. The connection method between the vertical beams 110, the first cross beams 120 and the second cross beams 130 includes but is not limited to welding, threaded connection and rivet connection. It should be noted that the sizes of the vertical beams 110, the first cross beams 120 and the second cross beams 130 and the number of the second cross beams 130 and the vertical beams 110 are designed according to actual conditions, and this embodiment does not impose specific restrictions on this.

[0039] It should be noted that the first horizontal frame is located above the second horizontal frame.

[0040] The first positioning structure is disposed at the front of the tooling platform 100 and is used to position the front of the first ceiling.

[0041] It should be noted that when the first roof needs to be positioned for subsequent assembly with the corresponding vehicle body, the front of the first roof is positioned and matched with the first positioning structure to achieve accurate fixation of the front of the first roof. The connection methods of the first positioning structure and the tooling platform 100 include but are not limited to welding, threaded connection and rivet connection.

[0042] The second positioning structure 300 is disposed at the rear of the tooling platform 100 and is used to position the rear of the first ceiling and the rear of the second ceiling respectively.

[0043] It should be noted that when the first ceiling needs to be positioned for subsequent assembly with the corresponding vehicle body, in addition to positioning and matching the front of the first ceiling with the first positioning structure, the rear of the first ceiling is also positioned and matched with the second positioning structure 300, so as to achieve stability in fixing the first ceiling. When the second ceiling needs to be positioned for subsequent assembly with the corresponding vehicle body, the rear of the second ceiling is positioned and matched with the second positioning structure 300 to achieve precise fixation of the rear of the second ceiling. That is, the rear of the first ceiling and the second ceiling are respectively positioned by the second positioning structure 300, which can reduce the number of parts required for positioning ceilings of different specifications and reduce manufacturing costs. The connection methods between the second positioning structure 300 and the tooling platform 100 include but are not limited to welding, threaded connection and rivet connection.

[0044] At least part of the third positioning structure 400 is movably arranged at the front end of the tooling platform 100 in the first position and the second position. The third positioning structure 400 is used to position the front part of the second ceiling when it is in the first position, and is used to avoid the first ceiling when it is in the second position. It should be noted that the size of the second ceiling along the front-to-back direction is greater than the size of the first ceiling along the front-to-back direction.

[0045] It can be understood that when it is necessary to assemble the first roof and the corresponding vehicle body, by making the third positioning structure 400 located in the second position, it is convenient to use the first positioning structure and the second positioning structure 300 to position and fix the first roof, and it will not affect the interference between the assembler and the tooling platform 100 when performing the assembly operation on the first roof, thereby ensuring the assembly efficiency; when it is necessary to assemble the second roof and the corresponding vehicle body, by making the third positioning structure 400 located in the first position, it is convenient to use the second positioning structure 300 and the third positioning structure 400 to position and fix the second roof, thereby realizing the positioning and fixing of two sizes of roofs on the same tooling platform 100, which not only meets the needs of co-production of multiple vehicle models, but also reduces the time and cost of research and development and production of additional tooling platforms 100, reduces manufacturing costs, and improves production efficiency and flexibility of subsequent assembly.

[0046] According to the ceiling tooling structure provided in the embodiment of the present application, the first positioning structure and the third positioning structure 400 located at the first position are used to position the front of the first ceiling and the second ceiling respectively, the second positioning structure 300 is used to position the rear of the first ceiling and the second ceiling respectively, and the third positioning structure 400 located at the second position avoids the first ceiling, thereby achieving positioning and fixing of two sizes of ceilings on the same tooling platform 100, which not only meets the needs of co-production of multiple vehicle models, but also reduces the time and cost of researching and developing and producing additional tooling platforms 100, reduces manufacturing costs, and improves production efficiency and flexibility of subsequent assembly.

[0047] In some embodiments, when the third positioning structure 400 is in the first position, at least part of the third positioning structure 400 is movably arranged on the tooling platform 100 along the front-to-back direction, that is, by adjusting the distance between the third positioning structure 400 and the second positioning structure 300 along the front-to-back direction, the second ceilings of different sizes can be positioned and fixed, further improving the scope of use of the ceiling tooling structure, thereby meeting the co-linear production requirements for second ceilings of different sizes, and reducing the time and cost of developing and producing additional tooling platforms, reducing manufacturing costs as much as possible, and improving production efficiency and flexibility of subsequent assembly. It can be understood that the first position of the third positioning structure 400 does not refer to a single coordinate that is relatively unchanged relative to the spatial position of the tooling platform 100, but as long as it can meet the requirements of positioning and fixing the second ceiling of the current size (that is, relative changes in the spatial position relative to the tooling platform 100), that is, the first position of the third positioning structure 400 has multiple positioning coordinates relative to the spatial position of the tooling platform 100, and each positioning coordinate corresponds to all the sizes of the second ceiling.

[0048] It should be noted that, in some embodiments, the first front support member 420, the second front support member 470 and the front positioning member 490 of the third positioning structure 400 are movably arranged on the first horizontal frame in the front-to-back direction, so as to realize that at least part of the third positioning structure 400 is movably arranged on the tooling platform 100 in the front-to-back direction. The structure for realizing the movement of the first front support member 420, the second front support member 470 and the front positioning member 490 in the front-to-back direction relative to the first horizontal frame includes but is not limited to a linear guide rail and a lead screw stepper motor, etc., and this embodiment does not impose specific restrictions on this.

[0049] In some embodiments, Figure 1 and Figure 2As shown, in order to realize that the third positioning structure 400 is movably arranged at the front end of the tooling platform 100 at the first position and the second position, the third positioning structure 400 includes a first mounting member 410 and at least one first front support member 420. The first mounting member 410 is rotatably mounted on the tooling platform 100 around a vertical axis; the first front support member 420 is rotatably mounted on the first mounting member 410 around an axis in the front-rear direction. The materials of the first mounting member 410 and the first front support member 420 include stainless steel, aluminum alloy or titanium alloy.

[0050] It should be noted that the vertical direction is the up and down direction.

[0051] It can be understood that the first mounting member 410 is rotatably installed on the tooling platform 100 by the rotating shaft 430 around the vertical axis, and the first front support member 420 is rotatably installed on the first mounting member 410 around the axis in the front-to-back direction by the hinge 440, that is, when the third positioning structure 400 is in the first position, the first mounting member 410 is located outside the front end of the tooling platform 100, and the first front support member 420 is located on the top surface of the first mounting member 410 (that is, the first front support member 420 and the first positioning pin 210 of the first positioning structure are spaced apart in the front-to-back direction); when the third positioning structure 400 is in the second position, the first mounting structure is located below the front of the tooling platform 100, and the first front support member 420 is located on the side or under the top surface of the first mounting member 410 (that is, the third positioning structure 400 is between the first horizontal frame and the second horizontal frame).

[0052] In some embodiments, based on the configuration of the inner top wall surface of the second ceiling, such as Figure 1 and Figure 2 As shown, the top surface of the first front support member 420 includes a support inclined surface that gradually tilts upward from the front to the back, and is used to abut against the front of the inner top wall of the second ceiling, so as to increase the contact area with the second ceiling as much as possible, and improve the stability of the abutment between the second ceiling and the first front support member 420. It should be noted that the size and inclination angle of the support inclined surface can be adaptively adjusted according to the second ceiling ribs, and this embodiment does not impose specific restrictions on this.

[0053] In some embodiments, Figure 1 and Figure 2As shown, two or more first front support members 420 are provided, and the two or more first front support members 420 are arranged at intervals on the first mounting member 410 along the front-to-back direction to further increase the contact area with the second ceiling and improve the stability of the abutment between the second ceiling and the first front support member 420. In this embodiment, there are two first front support members 420, and the first front support members 420 and the hinges 440 correspond one to one. It should be noted that the heights of the first front support members 420 may be different, as long as it can ensure that each first front support frame 460 can abut against the second ceiling, and this embodiment does not impose specific restrictions on this.

[0054] In this embodiment, the heights of the plurality of first front supporting members 420 gradually increase from front to back.

[0055] In some embodiments, Figure 2 As shown, the third positioning structure 400 further includes a fixing pin 450. A fixing hole is provided at the bottom of the first mounting member 410. One end of the fixing pin 450 passes through the fixing hole and is plugged into the tooling platform 100. The fixing pin 450 is made of stainless steel, aluminum alloy or titanium alloy.

[0056] It is understandable that the first mounting member 410 and the second crossbeam 130 of the second horizontal frame are plugged in by the fixing pin 450 to ensure that when the second ceiling is positioned, the first mounting member 410 will not rotate relatively along the vertical axis under the action of the rotating shaft 430 or external force so as to deviate from the first position, thereby ensuring the subsequent assembly accuracy and efficiency. It should be noted that the shape and number of the fixing block and the corresponding fixing pin 450 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0057] In some embodiments, Figure 1 and Figure 2 As shown, the third positioning structure 400 also includes two support frames 460 and two second front support members 470. The two support frames 460 are respectively installed on both sides of the front end of the tooling platform 100, and the first front support member 420 is located between the two support frames 460; the second front support member 470 corresponds to and is connected to the support frames 460 one by one, and the second front support member 470 is used to abut against the front of the inner wall of the second ceiling. The connection method between the support frame 460 and the tooling platform 100 and the connection method between the second front support member 470 and the support member include but are not limited to threaded connection, rivet connection, snap connection and welding. The material of the support frame 460 and the second front support member 470 includes stainless steel, aluminum alloy or titanium alloy.

[0058] It is understandable that by installing the support frame 460 on the left and right sides of the front end of the first horizontal frame, it is ensured that the second front support member 470 is simultaneously in contact with the inner side wall, outer side wall and bottom surface of the front of the second ceiling, so as to further increase the contact area with the second ceiling and improve the stability of the connection between the second ceiling and the third positioning structure 400. It should be noted that the shape and size of the second front support member 470 can be designed according to the second ceiling, and this embodiment does not impose specific restrictions on this.

[0059] In some embodiments, Figure 1 and Figure 2 As shown, the third positioning structure 400 also includes two clamping parts 480, which correspond to and are connected to the support frame 460 one by one, and the clamping parts 480 are located on the side of the second front support member 470 away from the first positioning structure, and are used to fix the wiring harness of the second ceiling. The connection method between the clamping part 480 and the support frame 460 includes but is not limited to threaded connection, rivet connection, snap connection and welding. The material of the clamping part 480 includes stainless steel, aluminum alloy or titanium alloy.

[0060] It is understandable that by positioning the clamping portion 480 at the front end and positioning the two clamping portions 480 at the left and right sides of the tooling platform 100, it is possible to ensure that the wiring harness is fixed without affecting the assembly of the second roof and the vehicle body. It should be noted that the shape of the clamping portion 480 and the distance between the clamping portion 480 and the second front support member 470 can be designed according to the second roof, and this embodiment does not impose any specific restrictions on this.

[0061] In some embodiments, Figure 1 and Figure 2 As shown, the third positioning structure 400 also includes two front positioning members 490, which are arranged at intervals along the left-right direction on the front end of the tooling platform 100, and the front positioning members 490 are located between the first front support member 420 and the first positioning structure, and are used to abut against the front of the top wall of the second ceiling. The connection between the front positioning member 490 and the tooling platform 100 includes but is not limited to threaded connection, rivet connection, snap connection and welding. The material of the front positioning member 490 includes stainless steel, aluminum alloy or titanium alloy.

[0062] It is understandable that by arranging the front positioning member 490 on the second cross beam 130 at the front end of the first horizontal frame, the front of the second ceiling can be supported more evenly, so as to further increase the contact area with the second ceiling and improve the stability of the connection between the second ceiling and the third positioning structure 400. It should be noted that the shape and size of the front positioning member 490, the distance between the two front positioning members 490, and the distance between the front positioning member 490 and the first front support member 420 can be designed according to the second ceiling, and this embodiment does not impose any specific restrictions on this.

[0063] In this embodiment, based on the structure of the inner top wall surface of the second ceiling, as shown in FIG. Figure 1 and Figure 2 As shown, the top surface of the front positioning member 490 gradually tilts upward from front to back to increase the contact area with the second ceiling as much as possible and improve the stability of the contact between the second ceiling and the front positioning member 490. It should be noted that the size and tilt angle of the top surface of the front positioning member 490 can be adaptively adjusted according to the second ceiling ribs, and this embodiment does not impose specific restrictions on this.

[0064] In some embodiments, Figure 1 and Figure 2 As shown, the top surface of the first ceiling is provided with a first positioning hole, and the first positioning structure includes a first positioning pin 210, which is installed on the tooling platform 100 for plugging and matching with the first positioning hole. The material of the first positioning pin 210 includes stainless steel, aluminum alloy or titanium alloy.

[0065] It can be understood that the first positioning hole is opened at the front of the top surface of the first ceiling, one end of the first positioning pin 210 is fixed to the front of the first horizontal frame, and the other end of the first positioning pin 210 is plugged into the first positioning hole, thereby realizing the first positioning structure positioning the front of the first ceiling. It should be noted that the shape and size of the first positioning pin 210 and the corresponding first positioning hole can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0066] In some embodiments, Figure 1 and Figure 2 As shown, the top surfaces of the first ceiling and the second ceiling are both provided with second positioning holes, and the second positioning structure 300 includes a second positioning pin 310, which is installed on the tooling platform 100 for plugging and matching with the second positioning hole. The material of the second positioning pin 310 includes stainless steel, aluminum alloy or titanium alloy.

[0067] It is understandable that the top front of the first ceiling and the second ceiling are both provided with a second positioning hole, one end of the second positioning pin 310 is fixed to the rear of the first horizontal frame, and the other end of the second positioning pin 310 is plugged into the second positioning hole, thereby realizing the first positioning structure to position the rear of the first ceiling and the second ceiling respectively. It should be noted that the shape and size of the second positioning pin 310 and the corresponding second positioning hole can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0068] In this embodiment, Figure 1 As shown, a plurality of second positioning pins 310 are provided, and the plurality of second positioning pins 310 are arranged on the first horizontal frame at intervals along the front-to-back direction to further improve the accuracy of positioning. It should be noted that the number of the second positioning pins 310 and the distance between two adjacent second positioning pins 310 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0069] In this embodiment, the centers of the plurality of second positioning pins 310 and the center of the first positioning pin 210 are collinear.

[0070] In some embodiments, Figure 1 and Figure 2 As shown, the second positioning structure 300 also includes a rear support member 320, which is arranged on the rear end of the first horizontal frame and is used to abut against the rear end of the top wall of the first ceiling or the second ceiling to further increase the contact area and improve the stability of the connection between the ceiling (including the first ceiling and the second ceiling) and the second positioning structure 300. The connection method between the rear support member 320 and the tooling platform 100 includes but is not limited to threaded connection, rivet connection, snap connection and welding. The material of the rear support member 320 includes stainless steel, aluminum alloy or titanium alloy, etc. It should be noted that the number and shape of the rear support member 320 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0071] In some embodiments, Figure 1 As shown, the ceiling tooling structure also includes two rear positioning members 600, which are arranged at intervals along the left-right direction on the rear of the tooling platform 100, and the rear positioning members 600 are located between the first positioning structure and the second positioning structure 300, and are used to abut against the rear of the top wall of the second ceiling. The connection between the rear positioning member 600 and the tooling platform 100 includes but is not limited to threaded connection, rivet connection, snap connection and welding. The material of the rear positioning member 600 includes stainless steel, aluminum alloy or titanium alloy.

[0072] It is understandable that by arranging the rear positioning member 600 on the second cross beam 130 located at the rear of the first horizontal frame, more uniform support for the rear of the second ceiling is achieved, so as to further increase the contact area with the second ceiling and improve the stability of the connection between the second ceiling and the third positioning structure 400. It should be noted that the shape and size of the rear positioning member 600, the distance between the two rear positioning members 600, and the distance between the rear positioning member 600 and the rear support member 320 can be designed according to the second ceiling, and this embodiment does not impose specific restrictions on this.

[0073] In some embodiments, Figure 1 and Figure 2 As shown, the ceiling tooling structure also includes a middle positioning structure, which is arranged on the tooling platform 100 and located between the first positioning structure and the second positioning structure 300, and is used to support the middle of the first ceiling or the second ceiling. The connection method between the middle positioning structure and the tooling platform 100 includes but is not limited to threaded connection, rivet connection, snap connection and welding.

[0074] It can be understood that by providing a middle positioning structure on the first horizontal frame, the contact area is further increased, the positioning accuracy and supporting strength of the ceiling are improved, so as to ensure that the ceiling will not deviate or shake during subsequent assembly.

[0075] In this embodiment, Figure 1 and Figure 2 As shown, the middle positioning structure includes two groups of positioning parts, and the positioning groups correspond to and are connected to the first crossbeam 120 of the first horizontal frame one by one. Each positioning group includes a plurality of positioning blocks 510 spaced apart along the front-to-back direction to further improve the positioning accuracy and support strength of the ceiling. It should be noted that the shape and size of each positioning block 510 can be adaptively adjusted according to the ceiling, and this embodiment does not impose specific restrictions on this. The material of the positioning block 510 includes stainless steel, aluminum alloy or titanium alloy, etc. The connection method between the positioning block 510 and the tooling platform 100 includes but is not limited to threaded connection, rivet connection, snap connection and welding.
