Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts testing devices, and in particular to an automotive door hinge inspection tool. Background Technology

[0002] Automotive door hinges are crucial components for enabling the functionality of car doors, affecting factors such as the comfort of door opening and closing, the reliability of door use, the sealing performance of the door, and the opening and closing performance of the door lock. Currently, hinges often require inspection after manufacturing to prevent dimensional or quality issues from affecting subsequent vehicle installation. However, existing inspection methods mostly rely on manual inspection, which is inefficient.

[0003] Therefore, a prior art automotive door hinge assembly inspection fixture, publication number CN218511682U, includes an inspection platform and a hinge fixture. The hinge fixture is provided with an installation port. Support seats are fixedly connected to both sides of the bottom of the inspection platform, and a support frame is fixedly connected to the top of the inspection platform. An industrial camera is fixedly connected to the center of the support frame. An installation seat is slidably connected to the bottom of the inspection platform. A drive is run to adjust the positioning pin, and then the hinge fixture is inserted into the interior of the positioning pin through the installation port. The drive is run to make the positioning pin abut against the outer wall of the installation port. A second electric telescopic rod is used to insert a conical cylinder into the interior of the installation port, thereby keeping the positioning pin at the center line of the installation port and keeping the hinge fixture in a fixed position. This allows the industrial camera to take pictures for inspection, improving the inspection accuracy of the hinge fixture.

[0004] When this device uses an industrial camera to image and inspect car door hinges, it can only capture one side of the hinge. If there is a manufacturing defect on the other side of the hinge, the device cannot immediately identify it, which limits its inspection capabilities and results in certain limitations in its functionality. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art, and to propose an automotive door hinge inspection tool.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automotive door hinge inspection tool, comprising an inspection platform, a square frame rotatably connected to the top surface of the inspection platform, threaded rods rotatably installed through each corner of the square frame, the threaded rods being divided into upper and lower parts equally by the square frame, and a placement plate slidably installed on both parts of any threaded rod, the two placement plates located on the same threaded rod being arranged opposite each other, limit rods penetrating through the opposite sides of the square frame, rubber sheets fixedly installed on the opposite end faces of the two limit rods, and springs fixedly installed between the other two end faces of the two limit rods and the adjacent sides of the square frame, and transmission between adjacent threaded rods via a transmission component.

[0007] Preferably, there are four threaded rods, and the transmission components include pulleys fixedly installed at both ends of the threaded rods. Among the four pulleys located on one side of the square frame, two belt strips are provided in pairs and are distributed parallel to the limiting rod. Among the four pulleys located on the other side of the square frame, two belt strips are provided in pairs and are distributed perpendicular to the limiting rod.

[0008] Preferably, a motor is fixedly connected to the square frame, and the motor spindle is fixed to one of the threaded rods.

[0009] Preferably, a pressure plate is provided between any pulley and the placement plate, which is threadedly connected to the threaded rod at a similar position; a push plate is provided between any placement plate and the square frame, which is sleeved with the threaded rod at a similar position; and a spring is also fixedly installed between the push plate and the square frame.

[0010] Preferably, a motor is also fixedly installed on the testing table, and the motor spindle located on the testing table is fixed to the square frame.

[0011] Preferably, it also includes a support frame for mounting the industrial camera, the support frame being plugged into the testing table and the plugging point being fixed by a pin.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows.

[0013] 1. In this utility model, after the car door hinge is placed on the placement plate, a motor drives the square frame to rotate, which in turn drives the car door hinge and the placement plate to rotate. While the placement plate follows the rotation of the square frame, the motor drives the threaded rod to rotate, causing it to rotate on its own axis. After the square frame completes its flip, the placement plate rotates half a turn and stops, and the car door hinge completes its flip. With this design, the industrial camera can capture and inspect both sides of the car door, improving the inspection capability.

[0014] 2. In this utility model, by setting a pressure plate and a push plate, when encountering car door hinges of different thicknesses, the distance between the pressure plate and the square frame is changed by rotating the pressure plate. Under the combined push of the push plate and the spring, the placement plate is pressed tightly against the pressure plate, thereby changing the distance between the placement plate and the square frame, thus coping with car door hinges of different thicknesses.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figure 1-4 As shown, an automotive door hinge inspection tool includes an inspection platform 1. A square frame 5 is rotatably connected to the top surface of the inspection platform 1. Threaded rods 6 are rotatably installed through each corner of the square frame 5. The threaded rods 6 are divided into upper and lower parts by the square frame 5. Placement plates 4 are slidably installed on both parts of any threaded rod 6. Two placement plates 4 located on the same threaded rod 6 are arranged opposite each other. Limiting rods 9 penetrate each opposite side of the square frame 5. Rubber sheets 7 are fixedly installed on the opposite end faces of the two limiting rods 9. Springs 13 are fixedly installed between the other two end faces of the two limiting rods 9 and the adjacent side faces of the square frame 5. The two adjacent threaded rods 6 are driven by a transmission component. A motor 3 is also fixedly installed on the inspection platform 1. The main shaft of the motor 3 located on the inspection platform 1 is fixed to the square frame 5.

[0023] In this technical solution, the main shaft of the motor 3 located on the testing table 1 rotates, driving the square frame 5 to rotate. At the same time as the square frame 5 rotates, the motor 3 located on the square frame 5 drives one of the threaded rods 6 to rotate. Through the transmission component, the rotation of one of the threaded rods 6 drives all the threaded rods 6 to rotate, thereby driving all the placement plates 4 to rotate. When the square frame 5 rotates half a turn, the placement plate 4 also rotates half a turn.

[0024] In addition, by setting a limit rod 9 and a spring 13, the fixture installed in the square frame 5 is clamped to prevent the fixture from sliding during the rotation of the square frame 5. The rubber sheet 7 is set to increase the contact area between the limit rod 9 and the fixture, which helps to improve the clamping stability of the limit rod 9.

[0025] like Figure 2 As shown, there are four threaded rods 6. The transmission components include pulley wheels 11 fixedly installed at both ends of the threaded rod 6. Among the four pulley wheels 11 on one side of the square frame 5, they are grouped in pairs and sleeved with belt strips 12 distributed parallel to the limiting rod 9. Among the four pulley wheels 11 on the other side of the square frame 5, they are grouped in pairs and sleeved with two belt strips 12 distributed perpendicular to the limiting rod 9. A motor 3 is fixedly connected to the square frame 5, and the main shaft of the motor 3 is fixed to one of the threaded rods 6.

[0026] In this technical solution, by setting the transmission components, when one of the threaded rods 6 rotates, it can drive all the threaded rods 6 to rotate. Specifically, the motor 3 on the square frame 5 works to drive one of the threaded rods 6 to rotate,带动 the two pulley wheels 11 fixed at both ends of one of the threaded rods 6 to rotate. The two pulley wheels 11 on one of the threaded rods 6 respectively drive the other pulley wheels 11传动连接 with them to rotate through the belt strips 12,从而带动 all the pulley wheels 11 to rotate,进而使 all the threaded rods 6 to rotate. Additionally, as Figure 4 所示, all the belt strips 12 are distributed in a "square" shape after combination.

[0027] 如 Figure 3 所示, a pressure plate 8 threadedly connected to the threaded rod 6 at a similar position is provided between any pulley wheel 11 and the placement plate 4, and a push plate 10 sleeved with the threaded rod 6 at a similar position is provided between any placement plate 4 and the square frame 5. A spring 13 is also fixedly installed between the push plate 10 and the square frame 5.

[0028] In this technical solution, when the pressure plate 8 rotates, the distance between the pressure plate 8 and the square frame 5 will change. Also, by setting the push plate 10 and the spring 13 installed at the push plate 10, when the pressure plate 8 rotates and the distance between the pressure plate 8 and the square frame 5 becomes larger, the spring 13 installed at the push plate 10 extends,推动 the push plate 10 to move towards the pressure plate 8,进而带动 the placement plate 4 to slide towards the pressure plate 8,使得 the distance between the two relatively arranged placement plates 4 increases,使 the placement plate 4 can place a car door hinge with a larger thickness. Additionally, the sliding installation method of the placement plate 4 and the threaded rod 6 can adopt the common methods in the existing technology. For example, a sliding groove is opened on the threaded rod 6, and a slider that slides in the sliding groove is fixed on the placement plate 4.

[0029] 如 Figure 1 所示, it further includes a support frame 2 for installing an industrial camera. The support frame 2 is inserted into the inspection table 1 and is fixed at the insertion point through a pin 14.

[0030] In this technical solution, rotating the pin 14 releases the fixed relationship between the support frame 2 and the testing table 1. After adjusting the height of the support frame 2, the pin 14 is reversed to fix the support frame 2 and the testing table 1, which can adjust the distance between the industrial camera and the placement plate 4, making the imaging effect clearer.

[0031] Working principle: Pull outwards the two limiting rods 9 to place the car door hinge inside the square frame 5, and place it above the placement plate 4 and between the two limiting rods 9. Then, release the two limiting rods 9. Under the action of the restoring force of the spring 13 fixed to them, the two limiting rods 9 move towards the car door hinge and clamp it. At this time, the hinge is fixed. After taking a picture of one side with an industrial camera, the main shaft of the motor 3 on the inspection table 1 rotates, driving the square frame 5 to rotate. At the same time, the motor 3 on the square frame 5 drives the threaded rod 6 to rotate. The rotation of the threaded rod 6 drives the placement plate 4 to rotate. When the square frame 5 and the placement plate 4 have rotated half a turn, they both stop. At this time, the car door hinge has completed the flipping, and the placement plate 4 does not block the industrial camera from taking pictures of the hinge.

[0032] The wiring diagram of motor 3 in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of motor 3 will not be explained in detail.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
