Description

Technical Field

[0001] This utility model relates to the field of automotive trim panel technology, and in particular to an inspection tool for automotive front door trim panel assembly. Background Technology

[0002] Door trim panels are decorative coverings installed on the inside of car doors. They are mainly used to beautify the interior, integrate functional components, and provide some sound insulation and protection.

[0003] The production of car door trim panels requires strict matching with surrounding components such as door sheet metal, dashboard, and window frame trim panels. Gap and surface difference tolerances typically need to be controlled within ±0.75mm. Excessive error can easily lead to assembly difficulties or even make assembly impossible. Current technology involves an operator placing the door trim panel on a mounting bracket and securing it by tightening multiple bolts, followed by inspection. However, manually tightening multiple bolts is time-consuming and makes it difficult to inspect the reverse side of the door trim panel, resulting in low inspection efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of low efficiency in manually fixing car door trim panels in the prior art, and to propose a car front door trim panel assembly inspection tool.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A prestressing fixture for a car front door trim panel assembly includes a lower clamping plate and an upper clamping plate disposed directly above the lower clamping plate. Two symmetrically arranged electric telescopic rods are fixedly installed on the lower clamping plate. The upper ends of the two electric telescopic rods are fixedly connected to the upper clamping plate through a rotating seat. The lower clamping plate and the upper clamping plate are each provided with four rectangular sliding grooves, and each of the four sliding grooves is provided with a limiting plate for limiting and fixing the door trim panel.

[0007] Preferably, both the lower clamping plate and the upper clamping plate are fixedly mounted with two pairs of symmetrically arranged fixing plates, and a bidirectional lead screw is rotatably mounted between the two pairs of fixing plates. A servo motor for driving the bidirectional lead screw to rotate is fixedly mounted on the outer wall of both pairs of fixing plates.

[0008] Preferably, the bidirectional lead screws on the lower clamping plate and the upper clamping plate are staggered, and nuts are threaded onto the outer walls of both ends of the bidirectional lead screws. Limiting plates are fixedly installed on the outer walls of the two nuts. Four sliding grooves are provided on both the lower clamping plate and the upper clamping plate, and the four limiting plates are slidably disposed in the four sliding grooves respectively.

[0009] Preferably, both ends of the lower clamping plate are rotatably mounted with rotating shafts, and both ends of the rotating shafts are rotatably mounted with fixing frames.

[0010] Preferably, a rotary motor is fixedly installed on the outer wall of the fixed frame, and the output end of the rotary motor is fixedly connected to the rotating shaft.

[0011] Preferably, two height sensors are fixedly installed on the upper clamping plate, and both height sensors are located directly above the two electric telescopic rods. A controller is fixedly installed on the outer wall of the fixing frame.

[0012] Preferably, a clamping plate is rotatably mounted on the side wall of the upper clamping plate relative to the side of the height sensor via a rotating seat, and multiple limiting holes are provided on both clamping plates, with fixing pins provided in the limiting holes. The side wall of the lower clamping plate is provided with fixing holes for placing the fixing pins.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This utility model uses the cooperation of the lower clamping plate and the upper clamping plate to limit the upper and lower ends of the car door trim panel. With the rotation of the bidirectional screw, the limiting plate and the side wall of the car door trim panel are made to fit together, thereby limiting and fixing the car door trim panel. This reduces the time required to manually tighten the bolts to fix the car door trim panel and improves the fixing efficiency of the car door trim panel.

[0015] 2. This utility model fixes the door trim panel, and a rotating motor drives the rotating shaft to rotate, causing the lower clamping plate to rotate and flip the door trim panel, which facilitates the inspection of the upper and lower ends of the door trim panel.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-3 A prestressing fixture for a front door trim panel assembly includes a lower clamping plate 1 and an upper clamping plate 2 positioned directly above the lower clamping plate 1. Two symmetrically arranged electric telescopic rods 12 are fixedly mounted on the lower clamping plate 1 by bolt assembly. The upper ends of the two electric telescopic rods 12 are fixedly connected to the upper clamping plate 2 via rotating seats. The lower clamping plate 1 and the upper clamping plate 2 are each provided with four rectangular sliding grooves 11 to limit the movement direction of the limiting plate 10, preventing the limiting plate 10 from rotating when the bidirectional lead screw 8 rotates. The limiting plate 10 is slidably arranged in each of the four sliding grooves 11 to limit and fix the door trim panel. The limiting plate 10 limits the horizontal direction of the door trim panel to prevent it from sliding.

[0022] Both the lower clamping plate 1 and the upper clamping plate 2 are fixedly mounted with two pairs of symmetrically arranged fixing plates 7 by bolt assemblies, and a bidirectional lead screw 8 is rotatably mounted between the two pairs of fixing plates 7. The outer walls of the two pairs of fixing plates 7 are fixedly mounted with servo motors 9 that drive the bidirectional lead screws 8 to rotate by bolt assemblies. Since the door trim panel is an irregular circular sheet structure, the four servo motors 9 drive the four bidirectional lead screws 8 to rotate, which facilitates the contact between the four limiting plates 10 and the side wall of the door trim panel, thereby limiting the door trim panel.

[0023] The bidirectional lead screws 8 on the lower clamping plate 1 and the upper clamping plate 2 are staggered. Nuts are threaded onto the outer walls of both ends of the bidirectional lead screws 8. Limiting plates 10 are fixedly installed on the outer walls of the two nuts. Four sliding grooves 11 are opened on both the lower clamping plate 1 and the upper clamping plate 2. The four limiting plates 10 are slidably set in the four sliding grooves 11 respectively.

[0024] Both ends of the lower clamping plate 1 are rotatably mounted with rotating shafts 3, and both ends of the two rotating shafts 3 are rotatably mounted with fixing brackets 4.

[0025] A rotary motor 5 is fixedly installed on the outer wall of the fixed frame 4 by bolt assembly, and the output end of the rotary motor 5 is integrally fixedly connected to the rotating shaft 3.

[0026] Two height sensors 16 are fixedly installed on the upper clamping plate 2 by bolt assembly, and both height sensors 16 are located directly above the two electric telescopic rods 12. A controller 6 is fixedly installed on the outer wall of the fixing frame 4 by bolt assembly to detect whether the heights at both ends of the upper clamping plate 2 are consistent, and to control the extension and retraction of the two electric telescopic rods 12 in real time through the controller 6.

[0027] A clamping plate 13 is rotatably mounted on the side wall of the upper clamping plate 2 relative to the side of the height sensor 16 via a rotating seat. Both clamping plates 13 are provided with multiple limiting holes 14, and a fixing pin 15 is provided in the limiting hole 14. The side wall of the lower clamping plate 1 is provided with a fixing hole for placing the fixing pin 15.

[0028] It should be noted that the bolt assembly is existing technology, specifically including bolts and bolt holes. The specific models and specifications of the controller 6 and height sensor 16 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts existing technology in this field, so it will not be elaborated here.

[0029] The functional principle of this utility model can be explained through the following operation methods:

[0030] The door trim panel is placed on the lower clamping plate 1. By extending and retracting the two electric telescopic rods 12, the height of one end of the upper clamping plate 2 is made to be flush with the height of the upper surface of the door trim panel. The upper clamping plate 2 rotates on the upper end of the electric telescopic rod 12, so that the upper clamping plate 2 is in contact with the upper surface of the door trim panel and parallel to the door trim panel. The fixing pin 15 is inserted from the limiting hole 14 into the fixing hole opened on the side wall of the lower clamping plate 1, so that the lower clamping plate 1 and the upper clamping plate 2 fix the upper and lower ends of the door trim panel.

[0031] Driven by the servo motors 9 installed on the lower clamping plate 1 and the upper clamping plate 2, the bidirectional lead screw 8 is rotated, and the two limit plates 10 on the bidirectional lead screw 8 move towards each other and stick to the side wall of the door trim panel to prevent the door trim panel from moving horizontally.

[0032] When the upper surface of the door trim panel is inspected, the output end of the rotary motor 5 drives the rotating shaft 3 to rotate, causing the lower clamping plate 1 to rotate, so that the upper clamping plate 2 is placed directly above the lower clamping plate 1, thus presenting the lower surface of the door trim panel for easy inspection of the upper and lower surfaces of the door trim panel.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
