Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, and in particular to a displacement detection device for the production of automotive metal corrugated pipes. Background Technology

[0002] Automotive metal bellows are commonly used to compensate for displacement in automotive pipelines. The bellows can absorb thermal expansion and mechanical displacement in the pipeline system, preventing pipeline rupture or loosening caused by displacement, and ensuring the connection flexibility of the exhaust system.

[0003] Therefore, before leaving the factory, the corrugated pipe needs to undergo displacement testing to determine whether the quality of the corrugated pipe meets the usage requirements. Generally, operators will use a tensile testing machine to test the tensile strength of the corrugated pipe. However, the tensile test cannot simulate the daily use of the corrugated pipe, and the resulting quality inspection data has limitations. Utility Model Content

[0004] The purpose of this application is to provide a displacement detection device for the production of automotive metal bellows, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A displacement detection device for automotive metal bellows production includes a workbench and a detection assembly mounted on the workbench surface. The detection assembly includes a rubber tray, a placement plate, and guide tubes. Two rubber trays are symmetrically arranged above the workbench surface and are movably mounted on the workbench surface. Two guide tubes are provided, with their outer walls fixedly connected to the edge of the workbench. Two placement plates are provided, each movably mounted on a guide tube. A feeding plate, which is arc-shaped, is fixedly mounted on one side of the workbench.

[0007] Preferably, two cylinders are fixedly installed on the workbench surface, symmetrically mounted on the workbench surface. A fixing component is fixedly installed at the output end of each cylinder, and a motor is fixedly installed on the fixing component. The output ends of the cylinders and the motors are arranged parallel to each other. A connecting rod is fixedly installed at the output end of the motor, and a rubber disc is fixedly installed at the end of the connecting rod furthest from the motor.

[0008] Preferably, a spring is fixedly installed inside the guide tube, and a guide rod is fixedly installed on the bottom surface of the placement plate. One end of the guide rod is embedded inside the guide tube, and the end of the guide rod away from the placement plate is fixedly connected to one end of the spring. Both the guide tube and the guide rod are arc-shaped, and the centers of the guide tube and the guide rod are both on the axis of the motor output shaft.

[0009] The beneficial effects of this utility model are: by setting up a detection component, the rubber discs on both sides drive the ends of the bellows to move, simulating the vibration of the bellows during vehicle use, thereby intuitively observing the deformation and displacement of the bellows.

[0015] like Figure 1-3 The device shown is a displacement detection device for the production of automotive metal bellows. It includes a workbench 1 and a detection component installed on the workbench 1. The detection component includes a rubber tray 7, a placement plate 8, and a guide tube 10. Two rubber trays 7 are arranged symmetrically above the workbench 1 and are movably mounted on the workbench 1. Two guide tubes 10 are arranged, and the outer walls of the two guide tubes 10 are fixedly connected to the edge of the workbench 1. Two placement plates 8 are arranged and are movably mounted on the guide tubes 10 respectively. A feeding plate 2 is fixedly installed on one side of the workbench 1. The feeding plate 2 is arc-shaped.

[0016] Two cylinders 3 are fixedly installed on the surface of the workbench 1. The two cylinders 3 are symmetrically installed on the surface of the workbench 1. A fixing part 5 is fixedly installed on the output end of the cylinder 3, and a motor 4 is fixedly installed on the fixing part 5. The output end of the cylinder 3 is parallel to the output end of the motor 4. A connecting rod 6 is fixedly installed on the output end of the motor 4, and a rubber disc 7 is fixedly installed on the end of the connecting rod 6 away from the motor 4.

[0017] A spring 11 is fixedly installed inside the guide tube 10, and a guide rod 9 is fixedly installed on the bottom surface of the placement plate 8. One end of the guide rod 9 is embedded inside the guide tube 10, and the end of the guide rod 9 away from the placement plate 8 is fixedly connected to one end of the spring 11. Both the guide tube 10 and the guide rod 9 are arc-shaped, and the centers of the guide tube 10 and the guide rod 9 are both on the axis of the output shaft of the motor 4.

[0018] Example: The two ends of the metal bellows to be tested are placed on two placement plates 8 respectively. Then, two motors 4 drive the connecting rod 6 to rotate, and the connecting rod 6 drives the rubber disc 7 to rotate. The rubber disc 7 moves to the end of the metal bellows. Then, the cylinder 3 drives the fixing part 5, and the fixing part 5 drives the motor 4. The motor 4 drives the rubber disc 7 to embed into the end of the bellows. The two rubber discs 7 are embedded into both ends of the bellows, thus fixing the bellows. Then, one side of the motor 4 starts, and the motor 4 drives the rubber disc 7. The rubber disc 7 drives the outer wall of the end of the bellows downward. Press the placement plate 8, which drives the guide rod 9. The guide rod 9 slides into the guide tube 10, and the spring 11 is compressed and deformed. At this time, one end of the bellows is pressed down. The operator observes whether the deformation and displacement of the bellows meet the standard. Then, the other side motor 4 is started. After the test is completed, the motor 4 drives the rubber disc 7 to rotate. The rubber disc 7 drives the metal bellows to move to the top of the unloading plate 2 of the workbench 1. The cylinder 3 extends its output end to separate the rubber disc 7 from the end of the bellows. The bellows falls from the unloading plate 2 to the collection point.
