Description

Technical Field

[0001] This application relates to the field of sheet metal inspection technology, and in particular to a strength inspection device for aerospace sheet metal parts. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming. Its significant characteristic is that the thickness of the same part is consistent. Products processed by sheet metal processing are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used as a term when assembling. Before use, the hardness of sheet metal parts will be tested.

[0003] The sheet metal strength testing device mentioned in the existing Chinese patent (authorization announcement number: CN219810744U) can drive the first screw to rotate in the first screw groove in the moving plate by activating the motor on the side plate. The moving plate can slide on the outer wall of the slide rod by the slide groove, which facilitates the moving plate to move the bottom testing device body to a suitable position. Then, people can use the testing device body to test different parts of the workpiece, which improves the testing effect of the workpiece and improves the practicality of the device.

[0004] When performing strength testing on sheet metal parts, the pressure change on the sheet metal parts is measured by the testing device itself when a load is applied, thereby completing the pressure test. However, if the load applied during the test exceeds the strength that the sheet metal parts can withstand, the sheet metal parts may break. During the breakage process, the sheet metal parts may generate debris, which requires staff to use brushes and vacuum cleaners to clean up the debris after the test is completed, which is quite inconvenient. Utility Model Content

[0005] The purpose of this application is to provide a strength testing device for aerospace sheet metal parts, in order to solve the problem that it is inconvenient for staff to use brushes and vacuum cleaners to clean up debris after the test.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A strength testing device for aerospace sheet metal parts includes a testing table, a testing frame fixedly connected to the top of the testing table, a placement platform installed on the top of the testing table, a hydraulic telescopic rod fixedly connected to the top of the testing frame, the output shaft of the hydraulic telescopic rod passing through the testing frame and fixedly connected to the testing device body, and a cleaning mechanism provided on the outside of the testing frame.

[0008] By adopting the above technical solution, the sheet metal part is placed on the placement platform of the testing table. Then, by controlling the extension and retraction of the hydraulic telescopic rod, the testing device body moves closer to the sheet metal part on the placement platform. Then, the testing device body is activated to perform relevant strength tests on the sheet metal part. After the sheet metal part is tested, it is removed from the placement platform, and the testing table and placement platform are cleaned. This completes the strength test of the sheet metal part. The cleaning mechanism reduces the inconvenience of manual cleaning.

[0009] Furthermore, the cleaning mechanism includes a rotary motor fixedly connected to the outside of the detection frame. The output shaft of the rotary motor passes through the detection frame and is fixedly connected to a threaded rod. A threaded block is threadedly connected to the outside of the threaded rod. A cleaning block is fixedly connected to the bottom end of the threaded block. When the cleaning block moves, it abuts against the placement platform.

[0010] By adopting the above technical solution, the rotary motor is started to drive the threaded rod to rotate. The threaded rod is threadedly connected to the threaded block, so that the threaded block moves horizontally on the outer surface of the threaded rod. At this time, the movement of the threaded block drives the cleaning block to move, so that the cleaning block cleans the top of the placement plate.

[0011] Furthermore, the cleaning block is symmetrically and fixedly connected to the outer side of the cleaning block, and the blocking block is configured in a figure-eight shape.

[0012] By adopting the above technical solution, the figure-eight shaped blocking block can gather the debris cleaned off the placement platform towards the center.

[0013] Furthermore, a guide rod is fixedly connected to the inner side of the detection frame, one end of the guide rod passes through the threaded block, and the guide rod is slidably connected to the threaded block.

[0014] By adopting the above technical solution, the threaded block can remain stable during movement.

[0015] Furthermore, the top of the testing platform has a through hole, the bottom of the testing platform is fixedly connected to a collection frame, the inner side of the collection frame is slidably connected to a collection box, the top of the collection box is set to be open, and the opening of the collection box is adapted to the through hole.

[0016] By adopting the above technical solution, the debris entering the through hole falls downwards, and the collection box is adapted to the through hole so that the debris falls into the collection box for storage.

[0017] Furthermore, the outer side of the collection box is symmetrically and fixedly connected with connecting blocks, the outer side of the collection frame is symmetrically and fixedly connected with limiting frames, the top of the limiting frame is slidably connected with a limiting rod, the bottom end of the limiting rod passes through the limiting frame and is fixedly connected with a limiting block, the top of the connecting block is provided with a limiting hole, the limiting block is adapted to the limiting hole, and the limiting block is adapted to the limiting hole.

[0018] By adopting the above technical solution, the collection box is fixed in the collection frame, which improves the stability of the collection box during operation.

[0019] In summary, this application includes at least one of the following beneficial effects;

[0020] 1. In this application, when cleaning the placement platform, the rotary motor is first started to drive the cleaning block to move, so that the cleaning block cleans the top of the placement plate, thereby realizing automatic cleaning of the placement plate, reducing the inconvenience of manual cleaning and achieving the purpose of improving efficiency.

[0021] 2. In this application, when collecting sheet metal parts, the collection box is adapted to the through hole so that the debris falls into the collection box and is stored there, which can effectively maintain the cleanliness of the testing environment and reduce the complexity of the cleaning work.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a strength testing device for aerospace sheet metal parts.

[0030] Reference Figure 1 and Figure 2A strength testing device for aerospace sheet metal parts includes a testing table 1, a testing frame 2 fixedly connected to the top of the testing table 1, a placement platform 3 installed on the top of the testing table 1, a hydraulic telescopic rod 4 fixedly connected to the top of the testing frame 2, the output shaft of the hydraulic telescopic rod 4 passing through the testing frame 2 and fixedly connected to the testing device body 5, and a cleaning mechanism provided on the outside of the testing frame 2.

[0031] When performing strength testing on sheet metal parts, the sheet metal parts are placed on the placement platform 3 of the testing table 1. Then, by controlling the extension and retraction of the hydraulic telescopic rod 4, the testing device body 5 is brought close to the sheet metal parts on the placement platform 3. The testing device body 5 is then activated to perform relevant strength tests on the sheet metal parts. After the sheet metal parts are tested, they are removed from the placement platform 3, and the testing table 1 and the placement platform 3 are cleaned. This completes the strength testing of the sheet metal parts. The cleaning mechanism reduces the inconvenience of manual cleaning.

[0032] Reference Figure 1 and Figure 3 The cleaning mechanism includes a rotary motor 6 fixedly connected to the outside of the detection frame 2. The output shaft of the rotary motor 6 passes through the detection frame 2 and is fixedly connected to a threaded rod 7. A threaded block 8 is threadedly connected to the outside of the threaded rod 7. A cleaning block 9 is fixedly connected to the bottom end of the threaded block 8. When the cleaning block 9 moves, it abuts against the placement table 3.

[0033] Among them, the outer side of the cleaning block 9 is symmetrically fixedly connected with the blocking block 11, and the blocking block 11 is set in a figure-eight shape.

[0034] In addition, a guide rod 10 is fixedly connected to the inner side of the detection frame 2. One end of the guide rod 10 passes through the threaded block 8, and the guide rod 10 is slidably connected to the threaded block 8.

[0035] When cleaning the placement platform 3, the rotary motor 6 is started first to drive the threaded rod 7 to rotate. The threaded rod 7 is threadedly connected to the threaded block 8, so that the threaded block 8 moves horizontally on the outer surface of the threaded rod 7. At this time, the movement of the threaded block 8 drives the cleaning block 9 to move, so that the cleaning block 9 cleans the top of the placement plate, thereby realizing automatic cleaning of the placement plate, reducing the inconvenience of manual cleaning, and achieving the goal of improving efficiency.

[0036] When the cleaning block 9 cleans the placement plate, the figure-eight blocking block 11 can gather the debris cleaned from the placement platform 3 towards the center, reducing the debris from scattering everywhere.

[0037] When the threaded block 8 moves, the guide rod 10 provides an additional support point for the threaded block 8, so that the threaded block 8 can remain stable when moving.

[0038] Reference Figure 2 and Figure 4The top of the testing platform 1 is provided with a through hole 12, and the bottom of the testing platform 1 is fixedly connected with a collection frame 13. The inner side of the collection frame 13 is slidably connected with a collection box 14. The top of the collection box 14 is set to be open, and the opening of the collection box 14 is adapted to the through hole 12.

[0039] The outer side of the collection box 14 is symmetrically and fixedly connected with a connecting block 15, and the outer side of the collection frame 13 is symmetrically and fixedly connected with a limiting frame 16. The top of the limiting frame 16 is slidably connected with a limiting rod 17, and the bottom end of the limiting rod 17 passes through the limiting frame 16 and is fixedly connected with a limiting block 18. The top of the connecting block 15 is provided with a limiting hole 19, and the limiting block 18 is adapted to the limiting hole 19.

[0040] When collecting sheet metal parts, the cleaning block 9 carries debris into the through hole 12. The debris in the through hole 12 falls downwards and is stored in the collection box 14, which is adapted to the through hole 12. When the debris in the collection box 14 reaches a certain amount, the staff can move the collection box 14 to clean the debris. This can effectively maintain the cleanliness of the testing environment and reduce the complexity of the cleaning work.

[0041] When limiting the collection box 14, the collection box 14 is placed in the collection frame 13. At this time, the collection box 14 drives the connecting block 15 into the limiting frame 16. After placement, the operator drives the limiting rod 17 to move. The movement of the limiting rod 17 drives the limiting block 18 into the limiting hole 19, thereby fixing the connecting block 15 and fixing the collection box 14 in the collection frame 13. This improves the stability of the collection box 14 during operation and reduces the risk of displacement of the collection box 14 during operation.

[0042] Working principle: The sheet metal part is placed on the placement platform 3 of the testing table 1. Then, by controlling the extension and retraction of the hydraulic telescopic rod 4, the testing device body 5 is moved closer to the sheet metal part on the placement platform 3. Then, the testing device body 5 is started to perform relevant strength tests on the sheet metal part. After the sheet metal part is tested, it is removed from the placement platform 3. The testing table 1 and the placement platform 3 are cleaned, thus completing the strength test of the sheet metal part. The rotary motor 6 is started to drive the threaded rod 7 to rotate. The threaded rod 7 is threadedly connected to the threaded block 8, so that the threaded block 8 moves horizontally on the outer surface of the threaded rod 7. At this time, the movement of the threaded block 8 drives the cleaning block 9 to move, so that the cleaning block 9 cleans the top of the placement plate.
