Description

Technical Field

[0001] The invention relates to the technical field of automobile parts detection, in particular to an automobile guard plate anti-impact testing device. Background Art

[0002] In the field of automobile manufacturing, the quality and performance of automobile guard plates are crucial to the safety and overall performance of the vehicle. Among them, impact resistance is one of the key indicators for evaluating the quality of automobile guard plates. In order to ensure that automobile guard plates can effectively withstand various impacts in actual use, accurate and reliable impact resistance tests are essential.

[0003] In the past, there were many problems and challenges in the development of automobile guard plate impact test technology. Early test devices often used relatively simple mechanical impact methods, such as using heavy objects to fall or mechanical push rods to hit. These methods not only made it difficult to accurately control the impact force and speed, but also failed to simulate the actual complex impact conditions, resulting in insufficient accuracy and reliability of the test results.

[0004] With the advancement of technology, some impact devices using hydraulic or electric drive have gradually appeared. However, these devices still have some defects in practical applications. The impact speed and force of some devices are limited and cannot meet the test requirements of high-intensity impact; some devices have complex structures and cumbersome operations, requiring multiple independent systems to control the impact, fixation and marking functions respectively, which not only increases the equipment cost and maintenance difficulty, but also reduces the efficiency and convenience of the test.

[0005] In terms of flatness observation of automobile guard plates after impact tests, the traditional method usually relies on manual visual observation, which is highly subjective, with large errors, and it is difficult to accurately and intuitively reflect the flatness changes of the guard plates. Moreover, due to the lack of an effective data recording mechanism, it is impossible to provide a clear and accurate basis for subsequent data analysis and comparison.

[0006] In summary, the existing automobile guard plate impact resistance test device cannot meet the automotive industry's demand for high-quality, high-efficiency, and high-precision testing of automobile guard plates. Therefore, there is an urgent need for an innovative test device that can overcome the above defects and achieve accurate, intuitive, efficient, and universal testing of the impact resistance of automobile guard plates.

[0040] The mounting frame 2 is fixedly provided with a mounting plate 28 , a fixing sleeve 29 is fixedly connected to the side of the mounting plate 28 , one end of the fixing sleeve 29 is fixedly connected to a second spring 30 , and a second pressing rod 31 is fixedly connected between the second spring 30 and the translation frame 22 .

A driving motor 20 is also fixedly provided on the top plate 12 , and an output shaft of the driving motor 20 is coaxially and fixedly connected to the driving gear 13 .

[0042] The impact assembly includes an air pressure tank 7 and a fixed tube 4 arranged above the base 1, an impact column 6 is slidably connected in the fixed tube 4, and the impact column 6 extends to one side of the plate to be tested 3. A connecting cover 9 is fixedly connected between the air pressure tank 7 and the fixed tube 4. A pressure channel connected to the fixed tube 4 and the inside of the air pressure tank 7 is provided in the connecting cover 9. A closing sleeve 10 is provided in the connecting cover 9. A communicating channel is penetrated through the closing sleeve 10. The closing sleeve 10 extends to the outside of the connecting cover 9 and is fixedly connected to a traction rod 11. The traction rod 11 is fixedly connected to the tooth plate 21.

[0043] The air pressure tank 7 is connected to an external air pump for inputting air into the air pressure tank 7 so that the air pressure tank 7 is in a high pressure state.

[0044] The base 1 is fixedly provided with a first mounting seat 5 which is fixedly connected to the fixing pipe 4 , and the base 1 is fixedly provided with a second mounting seat 8 which is fixedly connected to the air pressure tank 7 .

[0045] During the implementation of the present invention, firstly, air is input into the air pressure tank 7 through an air pump until the air pressure in the air pressure tank 7 reaches a set value, and then the board to be tested 3 is inserted into the slot, and then the driving motor 20 is controlled to start, and the driving motor 20 drives the driving gear 13 to rotate. The driving gear 13 drives the passive gear 14 and the rotating rod 16 to rotate on the one hand, and drives the toothed plate 21 to move toward the installation frame 2 on the other hand;

[0046] When the tooth plate 21 moves, the translation frame 22 is driven to move, and then the end plate 25 and the chess pressing rod are pulled to move by the first spring 26, so that the pressing seat 32 is driven to move and the plate to be tested 3 is pressed and fixed. At this time, the first spring 26 is stretched and the second spring 30 is compressed;

[0047] When the tooth plate 21 moves, it also drives the traction rod 11 to move, and then drives the sealing sleeve 10 to move, until the communication channel is connected with the pressure channel, and the high-pressure air in the air pressure tank 7 enters the fixed pipe 4, pushing the impact column 6, so that the impact column 6 moves at a high speed and hits the plate to be tested 3;

[0048] When the passive gear 14 rotates, it drives the winding wheel 17 to rotate, so that the winding wheel 17 rotates and reels the traction rope 18, thereby pulling the side support rod 27, the lifting seat 35 and the lifting plate 38 upward. After the impacted part of the test plate 3 bulges and deforms, the lifting plate 38 contacts the bulged part of the test plate 3 and is pushed to translate, thereby drawing a curve on the marking plate 39. The changing height of the curve indicates the deformation height of the test plate 3 after being impacted, from which the impact resistance of the test plate 3 can be inferred.

[0049] In the above process, since the impacting speed of the impacting column 6 on the plate to be tested 3 is fast, when the impacting column 6 impacts the plate to be tested 3 , the lifting plate 38 has not yet moved to the impacting position.

[0050] In addition, in order to increase the stability of the lifting plate 38, a third spring can be set in the translation groove 36, and the translation end plate 37 can be contacted with the inner wall of the translation groove 36 through the third spring. This method can ensure the stability of the lifting plate 38 during collision on the one hand, and on the other hand, it can make the translation end plate 37 follow the bulge of the test plate 3 after being hit to draw a complete and corresponding change curve.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
