Description

Technical Field

[0001] This utility model relates to the technical field of automobile manufacturing, and in particular to automotive trim panel straightening fixtures and interior trim panels. Background Technology

[0002] After demolding, automotive interior panels may deform during the cooling process due to material shrinkage. To avoid scrapping automotive interior parts, deformed automotive interior panels need to be corrected.

[0003] While shaping devices exist for correcting automotive interior panels, these devices primarily target the surface of the panels and lack the ability to correct the shaping holes within them. For example... Figure 1 As shown, the automotive interior panels have styling holes, which are mainly used to match the position of the corner window glass. Since the corner window glass is an auxiliary driving unit, the driver and passengers generally do not notice its existence. Therefore, the tolerance of the automotive interior panels that match it is generally set to be relatively large.

[0004] However, for high-end cars, the parts must be produced with greater precision. Since the existing technology lacks a corrective device for the shaping holes of the interior panels, it is urgent to develop a corrective tooling to solve the technical problem of deformation of the shaping holes of the interior panels. Utility Model Content

[0005] The present invention aims to provide a tooling for correcting automotive trim panels to solve the technical problem of deformation of the shaping holes in interior trim panels.

[0006] According to a first aspect of the present invention, an automotive trim panel straightening fixture includes:

[0007] A base is connected to a positioning pad, the surface of which forms a positioning support surface. The positioning pad is set along a first path, which is connected end to end and forms an orthopedic space inside.

[0008] A movable clamping mechanism is provided, which has a movable clamping block, and the positioning pad is located on the moving path of the clamping block;

[0009] The orthopedic mechanism includes a fixing block, a first orthopedic block, and a second orthopedic block. The fixing block, the first orthopedic block, and the second orthopedic block are all located within the orthopedic space. The fixing block, the first orthopedic block, and the second orthopedic block are arranged along the shape of the shaping hole. The first orthopedic block and the second orthopedic block both have a movement path toward the positioning pad block.

[0010] A hot air device having a hot air outlet facing the orthopedic space.

[0011] The automotive trim panel straightening fixture according to the present invention has at least the following beneficial effects: During processing, the interior trim panel to be straightened is first placed on the positioning support surface of the positioning pad block, and the edge position of the interior trim panel is fixed by a movable clamping mechanism. At this time, the fixing block, the first straightening block and the second straightening block are all located in the shaping hole of the interior trim panel. Before straightening, the interior trim panel is heated by a hot air device to soften it and enhance its plasticity. During straightening, the position of the fixing block remains unchanged, and the shaping hole is straightened by moving the first straightening block and the second straightening block. The interior trim panel after straightening can meet the standard tolerance, effectively improve the assembly accuracy, and thus improve the appearance quality of the automotive interior.

[0012] According to some embodiments of this utility model, both the first orthopedic block and the second orthopedic block are provided with pressing grooves on the side facing the positioning pad. The pressing grooves can press the edge of the shaping hole during orthopedic treatment to limit the deformation direction of the shaping hole and prevent deformation in another direction during orthopedic treatment.

[0013] According to some embodiments of this utility model, the automotive trim panel straightening fixture further includes an air-cooling device, which has a cold air outlet facing the straightening space. After the straightening is completed, the hot air device stops working, and the air-cooling device starts to accelerate the shaping of the interior trim panel.

[0014] According to some embodiments of the present invention, the orthopedic mechanism further includes a first driving device, the first driving device having a first telescopic part that extends and retracts along a straight line, the first telescopic part being connected to the first orthopedic block to drive the first orthopedic block to extend and retract.

[0015] According to some embodiments of the present invention, the orthopedic mechanism further includes a second driving device, the second driving device having a second telescopic part that extends and retracts along a straight line, the second telescopic part being connected to the second orthopedic block to drive the second orthopedic block to extend and retract.

[0016] According to some embodiments of this utility model, in order to simplify the structure, the fixing block is fixedly connected to the positioning pad block or the base. Since both the first orthotic block and the second orthotic block can be movable, and the shaping hole is generally triangular, fixing the fixing block can also meet the orthotic requirements.

[0017] According to some embodiments of this utility model, at least two positioning pads are provided, and the number of movable clamping mechanisms is consistent with the number of positioning pads. Although the positioning pads are arranged along the first path, it does not mean that the positioning pads must be arranged continuously. In order to save costs, the positioning pads can be divided into multiple parts, and different positioning pads can be arranged at intervals along the first path.

[0018] According to some embodiments of this utility model, the base includes a lower plate and an upper plate, with the upper plate located above the lower plate. At least one positioning pad is disposed on the upper plate, and at least one positioning pad is disposed on the lower plate. All movable clamping mechanisms are disposed on the upper plate. Through the above arrangement, the positioning and supporting surfaces have different height differences, allowing the interior trim panels to be placed at an angle for easy placement and removal, and to reduce interference.

[0019] According to some embodiments of the present invention, the hot air outlet of the hot air device is located on the positioning pad to optimize the installation space and reduce the risk of burns to production workers.

[0020] According to the second aspect of the present invention, the interior panel is shaped by the aforementioned automotive trim panel straightening fixture.

[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] like Figures 2 to 4 As shown, the automotive trim panel straightening fixture according to the first aspect of the present invention includes a base 100, a positioning pad 200, a movable clamping mechanism 300, a straightening mechanism 400, a hot air device 500, and an air-cooling device (not shown in the figures). The base 100 serves as the mounting reference, and the positioning pad 200, the movable clamping mechanism 300, the straightening mechanism 400, the hot air device 500, and the air-cooling device are all directly mounted on the base 100.

[0033] Specifically, the surface of the positioning pad 200 forms a positioning support surface 210, which is used to position and place the interior trim panel 600 to provide initial positioning of the interior trim panel 600. The positioning pad 200 is set along a first path, which is connected end to end and forms a shaping space 220 inside. When the interior trim panel 600 is positioned on the positioning pad 200, its shaping hole 610 is located exactly within the shaping space 220.

[0034] Although the positioning pads 200 are arranged along the first path, this does not mean that the positioning pads 200 must be arranged continuously. To save costs, the positioning pads 200 can be divided into multiple parts. In this embodiment, there are three positioning pads 200, which are arranged at intervals along the first path. The surfaces of the three positioning pads 200 together form the positioning support surface 210 described above. It is understood that the number of positioning pads 200 can also be one, two, four, etc., and is not limited to the above embodiment.

[0035] It should be noted that the first path is designed based on the shape of the interior panel 600. The first path is a virtual path and is not a structure inherent in the orthopedic fixture. This utility model introduces the first path to facilitate the description of the positional relationship of the positioning pads 200. As long as all the positioning pads 200 can form the orthopedic space 220, regardless of how the first path is set, it falls within the protection scope of this utility model.

[0036] In addition, the movable clamping mechanism 300 is used to fix the interior panel 600 placed on the positioning support surface 210. If there are at least two positioning pads 200, then the number of movable clamping mechanisms 300 is the same as the number of positioning pads 200; if there is only one positioning pad 200, that is, the positioning pads 200 are arranged continuously, then the number of movable clamping mechanisms 300 must be greater than the number of positioning pads 200.

[0037] Taking three positioning pads 200 as an example, three movable pressing mechanisms 300 are also provided. Each movable pressing mechanism 300 includes a first cylinder 310, a rotating frame 320 and a pressing block 330. The first cylinder 310 has a telescopic rod. A support frame 340 is hinged to the middle of the rotating frame 320 and fixedly connected to the first cylinder 310. One end of the rotating frame 320 is hinged to the telescopic rod and the other end of the rotating frame 320 is fixedly connected to the pressing block 330, so that the pressing block 330 has a moving path of swinging up and down. Each positioning pad 200 is located on the moving path of the corresponding clamping block 330. When the first cylinder 310 extends its telescopic rod upward, one end of the rotating frame 320 moves upward, causing the clamping block 330 to press towards the positioning pad 200. When the first cylinder 310 retracts its telescopic rod downward, one end of the rotating frame 320 moves downward, causing the clamping block 330 to unlock away from the positioning pad 200.

[0038] During processing, the production worker positions the interior trim panel 600 on the positioning support surface 210, and then activates all the movable clamping mechanisms 300, causing all the clamping blocks 330 to press against the interior trim panel 600. Under the combined action of the clamping blocks 330 and the positioning pads 200, the edge position of the interior trim panel 600 is fixed. Although the edge position of the interior trim panel 600 is fixed, its shaping holes 610 are not fixed. Therefore, the shaping holes 610 can be shaped in subsequent processes, while other parts of the interior trim panel 600 cannot be shaped, thus achieving localized shaping of the interior trim panel 600.

[0039] like Figure 1 As shown, this is a standard interior trim panel 600, which has a perforated opening 610. Since existing corner windows are generally triangular, the projection of the perforated opening 610 on the plane is also triangular. As can be seen from the figure, none of the three surfaces of the perforated opening 610 are straight; two surfaces are outwardly sloping surfaces 620, and the remaining surface is inwardly sloping surface 630. Taking the depth direction of the perforated opening 610 as the downward direction, the direction closer to the center of the perforated opening 610 as the inward direction, and the direction farther from the center of the perforated opening 610 as the outward direction, the aforementioned outwardly sloping surface 620 refers to the surface being inclined outwards from bottom to top, and the aforementioned inwardly sloping surface 630 refers to the surface being inclined inwards from bottom to top. The interior trim panel 600 is designed this way to improve the field of vision for occupants looking out through the perforated opening 610 from inside the vehicle. If all three sides of the shaped hole 610 are outward slopes 620, the driver's field of vision will be narrowed; if all three sides of the shaped hole 610 are inward slopes 630, although the driver's field of vision will be widened, the interior panel 600 will be difficult to demold during production, requiring special methods for production, and the manufacturing cost will increase sharply.

[0040] like Figures 2 to 4 As shown, to achieve the correction of the shaping hole 610, the correction mechanism 400 includes a first driving device 410, a second driving device 420, a fixing block 430, a first correction block 440, and a second correction block 450. The fixing block 430, the first correction block 440, and the second correction block 450 are all located within the correction space 220. The fixing block 430, the first correction block 440, and the second correction block 450 are arranged along a second path. The second path is connected end-to-end and is designed according to the shape of the shaping hole 610. The second path is a virtual path and not a structure inherent in the correction fixture. This invention introduces a second path to facilitate the description of the positional relationship between the fixing block 430, the first correction block 440, and the second correction block 450.

[0041] Specifically, the first driving device 410 can be a cylinder, which has a first telescopic part that extends and retracts in a straight line. The first telescopic part is connected to a first orthotic block 440, and the first orthotic block 440 has a movement path that moves closer to or away from the positioning pad 200 under the drive of the first driving device 410. Similarly, the second driving device 420 can be a cylinder, which has a second telescopic part that extends and retracts in a straight line. The second telescopic part is connected to a second orthotic block 450, and the second orthotic block 450 has a movement path that moves closer to or away from the positioning pad 200 under the drive of the second driving device 420. Since both the first orthotic block 440 and the second orthotic block 450 can be movably set, and the shaping hole 610 is triangular, fixing the fixing block 430 can also meet the orthotic requirements. Therefore, to simplify the structure, the fixing block 430 can be fixedly connected to the positioning pad 200 or the base 100. In this embodiment, the fixing block 430 is fixedly connected to the base 100.

[0042] Furthermore, both the first orthotic block 440 and the second orthotic block 450 are provided with pressing grooves 401 on the side facing the positioning pad block 200. The shape of the pressing grooves 401 matches the outer bevel surface 620 of the shaping hole 610. During orthotic shaping, the pressing grooves 401 can press the edge of the shaping hole 610 to limit the deformation direction of the shaping hole 610 and prevent the shaping hole 610 from deforming in another direction during orthotic shaping. Since the inner bevel surface 630 of the shaping hole 610 cannot be pressed, in this embodiment, the positions of the first orthotic block 440 and the second orthotic block 450 correspond to the two outer bevel surfaces 620 of the shaping hole 610, respectively, while the position of the fixing block 430 corresponds to the inner bevel surface 630 of the shaping hole 610.

[0043] During the positioning and placement of the interior trim panel 600, in addition to placing the interior trim panel 600 on the positioning support surface 210, the inner inclined surface 630 of the shaping hole 610 needs to be positioned between the fixing block 430 and the positioning pad block 200. Since the first straightening block 440 and the second straightening block 450 have been reset before straightening, one of the outer inclined surfaces 620 of the shaping hole 610 must be positioned between the first straightening block 440 and the positioning pad block 200, and the other outer inclined surface 620 must be positioned between the second straightening block 450 and the positioning pad block 200. During the straightening process, the first driving device 410 and the second driving device 420 respectively drive the first straightening block 440 and the second straightening block 450 to move towards the positioning pad block 200, and after the straightening is completed, the first driving device 410 and the second driving device 420 respectively drive the first straightening block 440 and the second straightening block 450 to reset towards the direction away from the positioning pad block 200.

[0044] For interior panels 600 with different sizes and specifications, since the positions of the first orthotic block 440 and the second orthotic block 450 are adjustable, the initial positions and orthotic positions of the first orthotic block 440 and the second orthotic block 450 can be adjusted to adapt to the orthotic requirements of different interior panels 600.

[0045] Before orthopedic treatment, the interior trim panel 600 can be heated using a hot air device 500 to soften it and enhance its plasticity. Specifically, the hot air device 500 includes a heater 510, a first fan (not shown in the figures), and a heating channel (not shown in the figures). The heater 510 and the first fan can be made of existing technology. The heater 510 is used to heat the air, and the first fan is used to blow the heated air toward the heating channel, which is located within the positioning pad 200. The heating channel has a hot air outlet facing the orthopedic space 220, so that the interior trim panel 600 placed on the positioning support surface 210 can be heated by the hot air device 500.

[0046] Furthermore, since the interior trim panel 600 only needs to be heated during the straightening process, if the hot air device 500 continuously outputs hot air into the straightening space 220, it will be difficult for the production worker to pick up and put down the interior trim panel 600. Therefore, the hot air device 500 needs to output hot air into the straightening space 220 intermittently. However, the heater 510 needs to be preheated when it is turned on. If the hot air device 500 achieves intermittent hot air output by starting and stopping the heater 510, then the waiting time for preheating will consume a lot of working time. For this reason, the hot air device 500 also includes a telescopic unit 520, which can be a cylinder, and its pneumatic rod is connected to the outlet module 530 with a hot air outlet.

[0047] When the telescopic unit 520 extends toward the orthopedic space 220, the hot air outlet is close to the orthopedic space 220. At this time, the outlet module 530 is connected to the heating channel, so that hot air can be discharged from the hot air outlet. When the telescopic unit 520 retracts, the hot air outlet is far away from the orthopedic space 220. At this time, the outlet module 530 is not connected to the heating channel, so that hot air cannot be discharged from the hot air outlet or hot air is discharged from other outlets, so as to achieve the technical effect of intermittent hot air output.

[0048] In some other embodiments, the heating channel may not be located inside the positioning pad 200, but may be located outside the positioning pad 200. However, since production workers may easily touch the external heating channel when picking up or placing the interior panel 600, which may cause burns to the production workers, this utility model preferably places the heating channel inside the positioning pad 200.

[0049] After the interior trim panel 600 is shaped, its temperature remains high, resulting in slow shaping. Therefore, an air-cooling device is needed to accelerate the shaping process. Compared to the hot air device 500, the air-cooling device is simpler in structure as it does not require heating. It consists only of a second fan and a cold air duct with a cold air outlet facing the shaping space 220. Since the second fan does not require preheating upon startup, the air-cooling device can be used and stopped immediately.

[0050] After the interior panel 600 has been shaped, the hot air device 500 stops heating the interior panel 600. At the same time, the air cooling device blows cold air onto the interior panel 600 to accelerate the cooling of the interior panel 600 and make its temperature drop rapidly to the shaping temperature.

[0051] Using the above structure, during processing, the interior panel 600 to be shaped is first placed on the positioning support surface 210 of the positioning pad 200, and the edge position of the interior panel 600 is fixed by the movable clamping mechanism 300. At this time, the fixing block 430, the first straightening block 440, and the second straightening block 450 are all located in the shaping hole 610 of the interior panel 600. Before straightening, the interior panel 600 is heated by the hot air device 500 to soften it and enhance its plasticity. During straightening, the position of the fixing block 430 remains unchanged, and the shaping hole 610 is straightened by moving the first straightening block 440 and the second straightening block 450. After straightening, the interior panel 600 can meet the standard tolerance. After the shaping process is complete, the hot air device 500 stops heating the interior panel 600. Simultaneously, the air-cooling device blows cold air onto the interior panel 600 to accelerate its cooling. Once the interior panel 600 has cooled and set, the production worker removes it and places it on a verification table for inspection. Only after passing the inspection can the next process proceed; otherwise, the shaping process will be repeated. Alternatively, the production worker can check a batch of interior panels 600 together to improve efficiency.

[0052] In some embodiments of this utility model, the base 100 includes a lower plate 110 and an upper plate 120, with the upper plate 120 located above the lower plate 110. At least one positioning pad 200 is connected to the upper plate 120, and at least one positioning pad 200 is connected to the lower plate 110. All movable pressing mechanisms 300 are connected to the upper plate 120. The upper plate 120 has clearance positions to avoid gaps in the straightening mechanism 400, and the first driving device 410 and the second driving device 420 are both connected to the lower plate 110. Through the above arrangement, the positioning support surface 210 has different height differences, allowing the interior panel 600 to be placed in an inclined manner for easy placement and removal, and to reduce interference.

[0053] like Figure 1As shown, the interior panel 600 according to the second aspect embodiment of the present invention is shaped by the automotive trim panel straightening fixture according to the first aspect embodiment of the present invention. After straightening, the interior panel 600 can meet the standard tolerance, effectively improve the assembly accuracy, and thus improve the appearance quality of the automotive interior.

[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
