Abstract
Description
Technical Field
[0001] The invention relates to the technical field of automobile detection, and in particular to a flexible detection device for three coordinates of automobile four doors and two covers. Background Art
[0002] During the automobile trial production process, in order to detect the size of the car door in real time to ensure the quality of the assembly, three-coordinate detection is generally used to measure the size of the parts and control the quality of the product. However, during the current three-coordinate measurement process, due to the different sizes, shapes, and hole positions of the car body doors, the three-coordinate detection brackets of different models are not universal. Since there are large differences in the sizes and shapes of the front and rear doors, front hoods, and rear hoods, in most cases, the doors of a model generally require three three-coordinate measurement brackets. In addition, during the automobile trial production process, when a model is completed, the detection bracket corresponding to its model often cannot be reused. New models need to redesign new detection brackets, which increases the cost of automobile research and development and causes a lot of waste.
[0003] Invention patent CN202310228419.1 provides a door measuring bracket. Since the fixed bracket adopts a pin shaft for positioning and fixing, it can only fix the door of a certain model and is not universal for doors of other models.
[0004] Invention patent CN202410498131.0 provides a method of fixed measurement using hinge installation, but due to differences in hinges used on cars of different models and different widths of doors of different models, the bracket can only be used on a certain model and is therefore not universal, and the bracket cannot perform fixed measurement on the front and rear covers.
[0005] Invention patent CN202222821841.1 proposes a three-coordinate detection bracket for a frameless door inner panel, but the bracket is fixed by a positioning pin, and the positioning device is fixed to the bracket by bolts. Therefore, the design can only be fixed to a certain type of vehicle, and it is relatively complicated to adjust the positioning device.
[0006] Invention patent CN202310622241.9 provides a blue light measurement bracket, but the bracket does not have a clamping mechanism. Therefore, during the three-coordinate measurement process, the car door will move when subjected to external force, causing the final measurement result to be invalid. Summary of the invention
[0007] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a three-coordinate flexible detection device for four doors and two lids of a car, which has a simple and reliable structure, a small size, and a low cost, and can complete fixed measurement of four doors and two lids of cars of different shapes and sizes.

[0013] Furthermore, the clamping device includes a Y-axis connecting rod, a circumferential connecting rod and a fixed block; one end of the Y-axis connecting rod is connected to the T-shaped slide, and the other end is rotatably connected to the circumferential connecting rod, and the end of the circumferential connecting rod is connected to the fixed block.
[0014] Furthermore, the Y-axis connecting rod and the circumferential connecting rod are provided with slotted holes, and the connection position with the T-type slide and the circumferential connecting rod is adjusted through the slotted holes on the Y-axis connecting rod to achieve forward and backward movement, and the circumferential connecting rod is rotated by passing bolts through the slotted holes on the Y-axis connecting rod and the circumferential connecting rod.
