Description

Technical Field

[0001] This utility model belongs to the field of positioning tooling technology, and in particular relates to a positioning device for spray painting of rear door trim panels. Background Technology

[0002] The tailgate trim panel is a plastic cover on the inside of the car's trunk. It is usually made of rigid plastic (such as PP polypropylene, ABS, etc.) through injection molding to provide structural support. Depending on the model, the surface will have different processing techniques. In some high-end models, the tailgate trim panel will be customized with a complex curved full-coverage pattern. In this case, in order to better protect the pattern, it is necessary to spray clear varnish on its surface.

[0003] The current method is to directly place the trim panel on the bracket for painting. However, since the bracket lacks effective positioning for the trim panel, it is difficult to achieve automated painting, which can easily lead to uneven painting or even local missed spots, which is not conducive to standardized production.

[0004] To address the aforementioned issues, this application proposes a rear door trim panel spray painting positioning device. Utility Model Content

[0005] The purpose of this utility model is to provide a rear door trim panel spraying positioning device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a rear door trim panel painting positioning device, used for positioning the trim panel during painting. The trim panel has longitudinal and transverse reinforcing ribs formed on its inner side. The positioning device includes a support base, which includes symmetrically arranged horizontal plates and support rods fixed sequentially between the two horizontal plates in a horizontal direction. The support rods support the inner side of the trim panel. Symmetrical side rods are also fixed at both ends of the horizontal plates. The device also includes:

[0008] The inner clamping plate is provided with several pieces via a first connecting rod. The inner clamping plate is provided with two symmetrical sets. The first connecting rod is hinged to the support rod. The longitudinal tie rod is clamped by the inward rotation of the two sets of inner clamping plates.

[0009] The outer clamping plate is provided with several pieces via a second connecting rod. The outer clamping plate is provided with two symmetrical sets. The second connecting rod is hinged to the support rod. The longitudinal tie rod is clamped by the outward rotation of the two sets of outer clamping plates.

[0010] Side clamps are hinged to side rods. The side clamps are provided in two symmetrical sets. The transverse tie rods are clamped by rotating the two sets of side clamps outward.

[0011] Furthermore, a motor is fixed to one end of the side rod, and two meshing bevel gears are rotatably connected to the side of the side rod. One of the bevel gears is fixed to the output end of the motor, and the two bevel gears are respectively fixedly installed to two third connecting rods on the same side.

[0012] Furthermore, a first driving bevel gear is fixed to one end of the third connecting rod, and a first driven bevel gear is fixed to one end of the inner clamping plate, which meshes with the first driving bevel gear.

[0013] Furthermore, a second driving bevel gear is fixed to the other end of the third connecting rod, and a second driven bevel gear is fixed to one end of the outer clamping plate, which meshes with the second driving bevel gear.

[0014] Furthermore, the meshing direction of the first driving bevel gear driving the first driven bevel gear is opposite to the direction of the second driving bevel gear driving the second driven bevel gear.

[0015] Furthermore, both the inner and outer clamping plates are located between two adjacent support rods.

[0016] Furthermore, the bottoms of the two horizontal plates are integrally fixed by a bracket.

[0017] This utility model has the following beneficial effects:

[0018] This invention adapts to the longitudinal and transverse bracing on the trim panel by setting rotating inner, outer, and side clamping plates. The symmetrical inner clamping plate can form an inward clamping force under the trim panel, and the angle of the inner clamping plate can prevent the trim panel from detaching upward. The symmetrical outer clamping plate can form an outward clamping force under the trim panel, complementing the inner clamping to prevent the trim panel from deforming. The symmetrical side clamping plates form an outward clamping force on both sides under the trim panel, thereby ensuring the precise positioning of the trim panel during painting.

[0019] This invention features multiple bevel gear structures and a single motor to simultaneously drive all clamping plates, offering advantages such as controllability and high consistency, which facilitates automated clamping.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] Please see Figure 1 - Figure 8 As shown, this utility model is a rear door trim panel spray painting positioning device, used for positioning the trim panel 6 during spray painting, as follows: Figure 3 As shown, the inner side of the trim panel 6 is formed with longitudinal tie rods 61 and transverse tie rods 62. The trim panel 6, longitudinal tie rods 61 and transverse tie rods 62 are integrally injection molded. The longitudinal tie rods 61 are evenly arranged along the inner contour of the trim panel 6, and the transverse tie rods 62 are evenly arranged along the width direction of the trim panel 6. The longitudinal tie rods 61 and transverse tie rods 62 are distributed in a cross shape.

[0035] The positioning device includes a support base 1, which includes symmetrically arranged horizontal plates 11 and support rods 12 fixed horizontally between the two horizontal plates 11. The support rods 12 support the inner side of the decorative panel 6. Symmetrical side rods 13 are also fixed at both ends of the horizontal plates 11. The device also includes:

[0036] The inner clamping plate 2 is provided with several pieces via the first connecting rod 21. The inner clamping plate 2 is provided with two symmetrical sets. The first connecting rod 21 is hinged to the support rod 12. The longitudinal tie rod 61 is clamped by the inward rotation of the two sets of inner clamping plates 2.

[0037] The outer clamping plate 3 is provided with several pieces via the second connecting rod 31. The outer clamping plate 3 is provided with two symmetrical sets. The second connecting rod 31 is hinged to the support rod 12. The longitudinal tie rod 61 is clamped by the outward rotation of the two sets of outer clamping plates 3.

[0038] Side clamp 4 is hinged to side rod 13. The side clamp 4 has two symmetrical sets. The transverse tie rod 62 is clamped by the outward rotation of the two sets of side clamp 4.

[0039] Specifically, a motor 5 is fixed on a side rod 13 at one end. Two meshing bevel gears 51 are rotatably connected to the side of the side rod 13. One of the bevel gears 51 is fixed to the output end of the motor 5. The two bevel gears 51 are respectively fixedly installed to two third connecting rods 41 on the same side. When the motor 5 starts, it directly drives one of the bevel gears 51. Then, under the meshing of the two gears, it drives the two third connecting rods 41 on the same side to rotate synchronously.

[0040] Specifically, one end of the third connecting rod 41 is fixed with a first driving bevel gear 42, and one end of the inner clamping plate 2 is fixed with a first driven bevel gear 22 that meshes with the first driving bevel gear 42.

[0041] Specifically, a second driving bevel gear 43 is fixed to the other end of the third connecting rod 41, and a second driven bevel gear 32 is fixed to one end of the outer clamping plate 3, meshing with the second driving bevel gear 43. Further, such as... Figure 6 As shown, a second driven bevel gear 32 is also fixed at the end of the second connecting rod 31 away from the motor 5. A rotating third connecting rod 41 and a side clamping plate 4 are also provided on the side of the side rod 13 away from the motor 5. A second driving bevel gear 43 is also fixed on the side clamping plate 4 to mesh with the second driven bevel gear 32, so as to realize the synchronous rotation of the two side clamping plates 4.

[0042] Specifically, in order to achieve the reverse rotation of the inner clamping plate 2 and the outer clamping plate 3 under a driving force, the meshing direction of the first driving bevel gear 42 driving the first driven bevel gear 22 is opposite to the direction of the second driving bevel gear 43 driving the second driven bevel gear 32. More specifically, when the third connecting rod 41 rotates, the first driving bevel gear 42 meshes with the first driven bevel gear 22, causing the first connecting rod 21 to rotate forward. At this time, the second driving bevel gear 43 meshes with the second driven bevel gear 32, causing the second connecting rod 31 to rotate in reverse.

[0043] Furthermore, both the inner clamping plate 2 and the outer clamping plate 3 are located between two adjacent support rods 12. In this embodiment, the inner clamping plate 2 and the outer clamping plate 3 are installed in a way that avoids the support rods 12. When the inner clamping plate 2 and the outer clamping plate 3 are rotated to the clamping state, they are lower than the support rods 12, which facilitates the installation of the decorative panel 6. After the inner clamping plate 2 and the outer clamping plate 3 are rotated, they protrude from the support rods 12 and clamp the longitudinal tie rods 61 on the decorative panel 6.

[0044] Furthermore, the bottom of the two horizontal plates 11 is fixed together by the bracket 14. The bracket 14 can also be replaced by a connector that works with automated conveying equipment, that is, the support rod 12 is installed on the automatic conveyor line. Automatic feeding can be achieved through the conveyor line, which is conducive to automated production.

[0045] It is understood that this utility model, by setting rotatable inner clamping plates, outer clamping plates, and side clamping plates, adapts to the longitudinal and transverse bracing structures on the trim panel and achieves precise positioning; the inner clamping plate provides inward clamping from below the trim panel and prevents the trim panel from detaching upward, the outer clamping plate provides outward clamping to complement and prevent deformation, and the side clamping plates clamp outward from both sides to enhance stability; in addition, all clamping plate movements are synchronously driven by a single motor in conjunction with a bevel gear mechanism, which has the advantages of strong controllability and high consistency, and facilitates automated clamping.

[0046] One specific application of this embodiment is as follows: Figure 1The image shows the positioning device in the clamping state. At this time, the trim panel 6 is placed directly on the support base 1. The longitudinal tie rod 61 and the transverse tie rod 62 at the bottom of the trim panel 6 are in contact with the support rod 12. The two ends of the trim panel 6 cover the side clamping plate 4.

[0047] When motor 5 is started, the output end of motor 5 drives two third connecting rods 41 to rotate simultaneously through the meshing of two split bevel gears 51. The third connecting rods 41 drive the side clamping plate 4 to rotate outward and make contact with the inner side of the transverse tie 62. The first driving bevel gear 42 on the third connecting rod 41 drives the first connecting rod 21 and the inner clamping plate 2 to rotate inward through meshing with the first driven bevel gear 22, ultimately clamping the longitudinal tie 61 inward. The second driving bevel gear 43 on the third connecting rod 41 drives the second connecting rod 31 and the outer clamping plate 3 to rotate outward through meshing with the second driven bevel gear 32, ultimately clamping the longitudinal tie 61 outward. After motor 5 is activated, it drives the inner clamping plate 2, the outer clamping plate 3, and the side clamping plate 4 to rotate 90° simultaneously and clamp and position the decorative panel 6.

[0048] After the painting is completed, start the motor 5 to work in reverse. The inner clamping plate 2, outer clamping plate 3, and side clamping plate 4 will rotate 90° in the opposite direction and be lower than the support rod 12. At this time, the painted trim 6 can be taken out from the positioning device.
