Description

Technical Field

[0001] The utility model relates to the field of inspection devices for FRP components, in particular to a device for inspecting the thickness uniformity of FRP components of EMUs. Background Technique

[0002] The FRP components in EMUs generally refer to various components made of composite materials. These components are made of glass fiber reinforced plastics, which are widely used in multiple parts of EMUs due to their excellent mechanical properties, low weight, corrosion resistance, and excellent processing performance.

[0003] However, most traditional inspection devices for the thickness uniformity of FRP components of EMUs require operators to manually place and adjust the components during limit clamping. This makes it take a long time for operators to place the components in the required positions and also takes time to disassemble them. This not only increases the workload of operators but also reduces the inspection efficiency of the device.

[0004] Therefore, technicians in this field have provided an inspection device for the thickness uniformity of FRP components of EMUs to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and an inspection device for the thickness uniformity of FRP components of EMUs is proposed. Compared with most traditional inspection devices for the thickness uniformity of FRP components of EMUs, this device is provided with a conveying mechanism and a clamping mechanism. When the component to be inspected is conveyed to the clamping frame after being separated from the conveyor belt, the laser sensor will detect it and start the conveying mechanism. When the conveying mechanism conveys the component to the inspection table and is detected by another laser sensor, the clamping frame will extend and adjust the position of the component to the center of the surface of the inspection table through the clamping plate, enabling the inspection mechanism to more effectively inspect the component, thereby reducing the trouble and burden of manual placement and adjustment by operators, and further improving the inspection efficiency of the device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] Refer to Figures 1-5 , an embodiment provided by the present utility model:

[0037] A device for detecting the thickness uniformity of FRP components of multiple unit trains, comprising a workbench 1. On both sides of the upper surface of the workbench 1, conveyor belts 4 are fixedly connected. At the four corners of the lower surface of the workbench 1, support legs 2 are fixedly connected. At the center of the front outer wall of the workbench 1, a control panel 3 is fixedly connected, enabling the operator to conveniently control the device through the control panel 3. At the front and rear ends of both sides of the upper surface of the workbench 1, baffles 5 are fixedly connected. By setting the baffles 5, the possibility of the position of the detected FRP components of multiple unit trains shifting is reduced. On one side of the upper surface of the workbench 1, a conveying mechanism 6 is arranged. The conveying mechanism 6 includes a fixed frame 601. At the center of the upper surface of the fixed frame 601, a multi-joint electric telescopic rod 602 is fixedly connected. The output end of the multi-joint electric telescopic rod 602 is fixedly connected with a fixing plate 603. The lower surface of the fixing plate 603 is hinged with a pushing plate 604. At the front and rear ends of the upper part of one side outer wall of the pushing plate 604, limit blocks 605 are fixedly connected;

[0038] In the middle of the upper surface of the workbench 1, a clamping mechanism 8 is arranged. The clamping mechanism 8 includes a storage groove 801, a sliding rod 808, and a bidirectional threaded rod 809. Around the inner bottom surface of the storage groove 801, two second electric telescopic rods 802 are fixedly connected. The output end of the second electric telescopic rod 802 is fixedly connected with a clamping frame 805. Limiting sliding grooves 807 are opened on the inner walls around the clamping frame 805. In the middle of the outer wall of the bidirectional threaded rod 809, a first bevel gear 8010 is fixedly connected. Around the lower surface of the clamping frame 805, two servo motors 8011 are fixedly connected. The output end of the servo motor 8011 is fixedly connected with a second bevel gear 8012. A first clamping plate 8013 and a second clamping plate 8014 are respectively slidably connected to the inner walls of the limiting sliding grooves 807. On one side outer wall of the first clamping plate 8013, a plurality of first positioning sliding grooves 8015 are opened. On one side outer wall of the second clamping plate 8014, a plurality of second positioning sliding grooves 8016 are opened;

[0039] At the rear end of the middle part of the upper surface of the workbench 1, a detection mechanism 7 is arranged. The detection mechanism 7 includes a placement rack 701, a first electric telescopic rod 702, a detection module 703, a detection table 704, and a laser sensor 705.

[0040] Compared with the traditional detection device for the thickness uniformity of most FRP components of multiple units, this device is provided with a conveying mechanism 6 and a clamping mechanism 8. When the component to be detected is conveyed to the clamping frame 805 after being separated from the conveyor belt 4, the laser sensor 705 will detect it and start the conveying mechanism 6. When the component is conveyed to the detection table 704 and detected by another laser sensor 705, the clamping frame 805 will extend and adjust the position of the component to the center of the surface of the detection table 704 through the clamping plate, so that the detection mechanism 7 can detect the component more effectively, thereby reducing the trouble and burden of manual placement and adjustment by the user, and then improving the detection efficiency of this device.

[0041] The storage groove 801 is opened at the center of the upper surface of the workbench 1. Two through grooves 803 are opened on the inner bottom surface of the storage groove 801. By setting the storage groove 801, the clamping frame 805 can be stored in the workbench 1. Two limit blocks 804 are fixedly connected to the inner walls around the storage groove 801. Two limit slots 806 are opened on the outer walls around the clamping frame 805, so that the clamping frame 805 can rise or fall smoothly in the storage groove 801. The slide rod 808 and the bidirectional threaded rod 809 are both arranged inside the limit chute 807. The first bevel gear 8010 meshes with the second bevel gear 8012, so that the servo motor 8011 can drive the bidirectional threaded rod 809. The first electric telescopic rod 702 is fixedly connected to the front end of the upper surface of the placement frame 701. The detection module 703 is fixedly connected to the output end of the first electric telescopic rod 702, so that the first electric telescopic rod 702 can adjust the distance between the detection module 703 and the detection table 704. The detection table 704 is fixedly connected to the center of the inner bottom surface of the storage groove 801. The laser sensors 705 are respectively fixedly connected to the upper surfaces of the detection table 704 and the workbench 1, so that the laser sensors 705 can detect the positions of the FRP components of the multiple units passing on the workbench 1 and the detection table 704.

[0042] Working principle: First, place the device in the required position. When the FRP components of the EMU are conveyed to the middle of the surface of the workbench 1 by the conveyor belt 4 on one side of the device and are detected by the small laser sensor 705, the push plate 604 resets and the multi-joint electric telescopic rod 602 starts to control the push plate 604 to push the component to move. When the component covers the large laser sensor 705, the multi-joint electric telescopic rod 602 retracts completely. The second electric telescopic rod 802 pushes out the clamping frame 805, and the servo motor 8011 controls the first clamping plate 8013 and the second clamping plate 8014 to adjust the horizontal and vertical positions of the component respectively. When the servo motor 8011 reaches the set torque threshold due to the clamping plate touching the component (the torque threshold of the servo motor 8011 can be adjusted through the control panel 3. In the existing servo motor 8011, when the servo motor 8011 encounters resistance due to the clamping plate touching the component during rotation and the torque threshold is reached, the control system can control the servo motor 8011 to stop rotating), the clamping plate stops pressing on the component. At this time, the component is at the center of the surface of the detection table 704 and directly below the detection module 703. When the second electric telescopic rod 802 starts, the conveyor belt 4 on one side starts to move a new component to the small laser sensor 705, which jacks up the push plate 604 and stops moving. After the detection is completed, the clamping frame 805 retracts, and the multi-joint electric telescopic rod 602 pushes the detected component onto another conveyor belt 4 and retracts completely again. After a period of time, the conveyor belt 4 on one side starts again and repeats the process.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
