Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery parts technology, and in particular to a testing device for the strength of agricultural machinery parts. Background Technology

[0002] Agricultural machinery parts are a broad category encompassing all mechanical parts related to agricultural production. They include a wide range of items such as tractor power machinery parts, tires, and truck beds; harvesters including potato harvesters and peanut harvesters; agricultural implements (pear, harrow, and sowing); plows, including disc plows, moldboard plows, and animal-drawn plows; and harvester parts such as cutting blades and cutting tables.

[0003] After production, cutting tools undergo strength testing to assess their ability to withstand various loads and stresses in actual use. This testing process involves tensile testing, bending testing, and torsion testing. Traditional testing equipment can only perform one type of test, resulting in a limited testing range. Therefore, a strength testing device for agricultural machinery parts is proposed. Utility Model Content

[0012] Preferably, the protective component includes a protective plate disposed on the outside of the test frame, and a rotatable door is provided on the protective plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The agricultural machinery parts strength testing device is equipped with a moving component that places the cutting tool on the first clamping plate and the second clamping plate. The telescopic cylinder moves the first clamping plate, which can test the tensile strength of the cutting tool. The rotating component also clamps the cutting tool when it is necessary to test the torsional bending strength of the cutting tool.

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

[0021] Example: Refer to Figure 1-4 A testing device for the strength of agricultural machinery parts includes a testing frame 1 and a cutting tool 4. A first clamping plate 2 is mounted on the testing frame 1 via a moving component, and a second clamping plate 3 is mounted on the testing frame 1 via a rotating component. The cutting tool 4 is clamped between the first clamping plate 2 and the second clamping plate 3. The moving component includes a telescopic cylinder 5 fixedly mounted on the side of the testing frame 1. The output end of the telescopic cylinder 5 is fixedly connected to the side of the first clamping plate 2. A moving limiting post 6 is fixedly mounted on the side of the first clamping plate 2, and one end of the moving limiting post 6 extends outside the testing frame 1. When testing the tensile strength of the cutting tool 4, the cutting tool 4 is placed between the first clamping plate 2 and the second clamping plate 3. Clamping and fixing blocks are provided on the clamping plate 3, the first clamping plate 2, and the second clamping plate 3. The cutting tool 4 is clamped and fixed by traditional thread tightening. Some cutting tools 4 are also provided with positioning through holes. After direct insertion and positioning, the position can also be fixed. After the cutting tool 4 is clamped, the telescopic cylinder 5 is started to move, which drives the first clamping plate 2 to move. By moving and pulling, the tensile strength of the cutting tool 4 can be tested. During the test, a tension sensor can be set between the first clamping plate 2 and the output end of the telescopic cylinder 5 to detect the value of the tension. The moving limit post 6 can limit the position of the first clamping plate 2.

[0022] Specifically, the rotating assembly includes a rotating shaft 7 fixedly installed on the side of the second clamping plate 3. One end of the rotating shaft 7 extends outside the test frame 1 and is fixedly sleeved with a rotating gear 8. A moving cylinder 9 is fixedly installed on the side of the test frame 1. The output end of the moving cylinder 9 is connected to a rack 10, which meshes with the rotating gear 8. A limit groove 11 is formed on one side of the test frame 1, and a limit block 12 is fixedly installed on one side of the rack 10. The limit block 12 is slidably installed in the limit groove 11. When it is necessary to twist and bend the cutting tool 4, During the strength test, the cutting tool 4 is clamped, and then the moving cylinder 9 is activated, which drives the rack 10 to move. After the rack 10 moves, it drives the rotating gear 8 to rotate, which in turn drives the rotating shaft 7 to rotate. The second clamping plate 3 will rotate. Through rotation, the torsional bending strength of the cutting tool 4 can be detected. The limiting groove 11 and the limiting block 12 can limit the position of the rack 10. A high-definition camera is set in the test frame 1 to capture the test scene in real time for later data analysis.

[0023] Specifically, the test frame 1 is equipped with a lifting impact assembly located above the cutting tool 4. The lifting impact assembly includes a top rod 14 fixedly installed on the top of the test frame 1, a lifting cylinder 15 installed on the top rod 14, and an impact block 16 connected to the output end of the lifting cylinder 15. The impact block 16 is located above the cutting tool 4. A height gauge 17 is fixedly installed at the bottom of the top rod 14, and a bottom protective pad 13 is provided at the bottom of the test frame 1. When performing the impact resistance test, the cutting tool 4 is clamped and fixed, and the impact block 16 is installed on the output end of the lifting cylinder 15. The connection method here is hooking or magnetic attraction. After being lifted to a specified height, it can automatically fall off. After falling off, the impact block 16 falls directly onto the cutting tool 4 to perform the impact resistance test. The height gauge 17 can measure different falling heights, and the bottom protective pad 13 protects the bottom to prevent the impact block 16 from damaging the test frame 1 after falling.

[0024] Specifically, a protective component is provided on the outside of the test frame 1. The protective component includes a protective plate 18 on the outside of the test frame 1. A switch door 19 is rotatably provided on the protective plate 18. The protective plate 18 can provide protection from the surroundings to prevent the cutting tool 4 from breaking and flying out during the test, which could cause injury to the health of the staff.

[0025] In use: After production, the cutting blade 4 used in agricultural machinery parts needs to be tested for strength. The cutting blade 4 is placed on the first clamping plate 2 and the second clamping plate 3. The telescopic cylinder 5 is activated, which moves the first clamping plate 2. The tensile strength of the cutting blade 4 can be tested by moving and pulling. When the torsional bending strength of the cutting blade 4 needs to be tested, the cutting blade 4 is clamped in the same way. The moving cylinder 9 is activated, which drives the rotating shaft 7 to rotate. The second clamping plate 3 will rotate. The torsional bending strength of the cutting blade 4 can be detected by rotating. When the impact resistance test is carried out, the cutting blade 4 is clamped and fixed. The impact block 16 is installed on the output end of the lifting cylinder 15. After being lifted to a specified height, it will automatically fall off. The impact block 16 will fall directly on the cutting blade 4 to carry out the impact resistance test. The protective plate 18 can protect from the surroundings and prevent the cutting blade 4 from breaking and popping out during the test, which could cause injury to the health of the workers. It is easy to use.
