Description

Technical Field

[0001] The present invention relates to the technical field of large track link processing, and specifically to an impact strength testing device for track links and an operation method thereof. Background Art

[0002] Track links are the connecting parts used in the tracks of construction machinery such as excavators and bulldozers, as well as military machinery such as tanks. During the production process of track links, it is usually necessary to detect their quality to determine whether they are qualified. An impact testing machine is an important part for detecting the quality strength of track links, and it is necessary to conduct impact tests on track links. For example, the patent with the application number 201920807041.X discloses a track link impact testing machine, and its technical solution solves the technical problems of track link fracture and flying out, and relatively high potential safety hazards. However, it has problems such as being unable to impact track links at different heights, having a single impact testing method, low safety during the impact process of track links, and low accuracy of impact test results.

[0003] Based on this, we propose an impact strength testing device for track links and an operation method thereof. Summary of the Invention

[0004] The purpose of the present invention is to provide an impact strength testing device for track links and an operation method thereof, which are reasonable in structural design, can impact track links at different heights, have rich impact methods, good safety during the impact process of track links, and high accuracy of impact test results, aiming at the problems existing in the existing impact strength testing device for track links, such as being unable to impact track links at different heights, having a single impact testing method, low safety during the impact process of track links, and low accuracy of impact test results.

[0005] The technical solution adopted by the present invention to solve the technical problems is as follows:

[0006] An impact strength testing device for track links, comprising a base, a bearing structure, and a loading structure. The base is arranged on a bracket, a bearing frame is arranged on the base, and a height-adjusting structure is arranged on the bearing frame. The bearing structure includes positioning columns and a bearing plate. The positioning columns are arranged on the base, an installation cylinder is arranged on the back of the bearing plate, and the installation cylinder is sleeved on the positioning columns. The track link to be subjected to impact strength testing is placed on the bearing plate. The impact block moves downward under the action of gravity to impact the track link on the bearing plate. The height of the impact block can be adjusted through the height-adjusting structure, and the falling height of the impact block can be adjusted, facilitating the impact of the track link by the impact block at different heights to conduct a comprehensive impact strength test on the track link. The loading structure is movably arranged on the height-adjusting structure. The loading structure and the bearing plate are set in a one-to-one correspondence structure, and a blanking structure is arranged on the loading structure. The impact block is placed on the loading structure, and the blanking structure automatically drops the impact block to enable the impact block to impact the track link and analyze and evaluate the impact strength of the track link.

[0007] Preferably, a bottom plate is arranged at the bottom of the bracket, and a shock-absorbing pad is arranged on the bottom plate. On the one hand, the shock-absorbing pad can improve the stability of the testing device during operation. On the other hand, the shock-absorbing pad can reduce the impact force received by the base when the track link is impacted by the impact block, improving the shock-absorbing effect of the testing device during operation.

[0008] Preferably, a scale is arranged on the outer wall of the bearing frame. The falling height of the impact block can be determined through the scale. According to the falling height of the impact block and the weight of the impact block, the impact force when the impact block impacts the track link can be obtained. The impact situation of the impact block on the track link can be used to infer the impact strength of the track link in reverse, providing data support for continuously improving the impact strength of the track link.

[0009] Preferably, the height adjustment structure includes a driving motor and an adjustment plate. The driving motor is set as a servo motor. A bearing is provided on the base. The driving motor is arranged on the top of the carrier. A transmission stud is provided on the driving motor, and the bottom end of the transmission stud is inserted into the bearing. The adjustment plate is provided with a connecting screw cylinder, a fixing screw cylinder and a blanking cylinder. The connecting screw cylinder is sleeved on the transmission stud. The material loading structure is movably arranged on the adjustment plate, and the material loading structure corresponds to the blanking cylinder one by one. The driving motor drives the transmission stud to rotate forward or backward. The transmission stud pushes the connecting screw cylinder to rise or fall, driving the adjustment plate and the discharging plate on the adjustment plate to rise or fall. According to the impact test method, the adjusting stud is rotated through the handle to adjust the height of the corresponding discharging plate, so that multiple discharging plates are at the same or different heights. The material loading structure corresponds to the blanking cylinder one by one, and the same track link can be impacted by impact blocks of different weights or the anti-impact strength test of different track links can be carried out on the same impact block, enriching the test methods of anti-impact strength.

[0010] Preferably, a limiting groove is provided on the inner wall of the carrier. Limiting columns are provided on the outer walls of the opposite sides of the adjustment plate, and the limiting columns are inserted into the limiting grooves. The adjustment plate rises or falls under the action of the driving motor, and the limiting columns rise or fall in the limiting grooves, which can limit the vertically moving adjustment plate and improve the stability of the adjustment plate during vertical movement, so that the impact block can accurately impact the track link, thereby improving the accuracy of the test results.

[0011] Preferably, a fixing rod is provided on the outer wall of the blanking cylinder. A protective cylinder is movably arranged on the blanking cylinder. A through groove and a hanging groove communicated with the through groove are provided on the protective cylinder, and the fixing rod passes through the hanging groove. After the height of the adjustment plate is adjusted, the protective cylinder on the blanking cylinder is rotated to make the fixing rod enter the through groove. The height of the protective cylinder on the blanking cylinder is moved up and down to make the bottom end of the protective cylinder cover the bearing plate. After the height adjustment of the protective cylinder is completed, the protective cylinder is rotated to make the fixing rod enter the hanging groove. The bearing plate is covered by the protective cylinder to prevent the impact block or the track link from splashing when the impact block impacts the track link, and improve the safety of the track link during the anti-impact strength test.

[0012] Preferably, the material loading structure includes an adjusting stud and a discharging plate. The adjusting stud vertically passes through the fixed screw cylinder. A connecting cylinder is provided at the bottom of the discharging plate. A discharging groove and a blanking structure are provided on the discharging plate. The discharging groove is vertically communicated with the blanking cylinder. The connecting cylinder is movably connected to the top end of the adjusting stud. The discharging plate is arranged as a structure that can adjust its height on the adjusting plate through the adjusting stud. The impact block is placed in the discharging groove on the discharging plate. By rotating the adjusting stud with a handle, the clamping block on the adjusting stud rotates in the clamping groove in the connecting cylinder, so that the adjusting stud can push the discharging plate up or down, thereby further adjusting the height of the impact block, enabling the same impact block to impact the track link at different heights, further enriching the test method, and thus improving the accuracy of the test results.

[0013] Preferably, a handle is provided at the bottom end of the adjusting stud, and a clamping block is provided at the top end of the adjusting stud. A clamping groove is provided on the inner wall of the connecting screw cylinder, and the clamping block is arranged in the clamping groove. By rotating the adjusting stud with a handle, the clamping block on the adjusting stud rotates in the clamping groove in the connecting cylinder, so that the adjusting stud can push the discharging plate up or down, enabling multiple discharging plates to be at the same or different heights, so that the track link can be impacted at different heights, and a comprehensive impact resistance test is carried out on the track link, thereby improving the accuracy of the test results.

[0014] Preferably, the blanking structure includes a hydraulic cylinder and a moving plate. A fixed groove is provided on the inner wall of the discharging groove, and a blocking rod is provided on the inner wall of the discharging groove above the fixed groove. The hydraulic cylinder is arranged on the outer wall of the discharging plate, and a piston rod is provided on the hydraulic cylinder and extends into the discharging groove. Both ends of the moving plate are inserted into the fixed groove, and the moving plate is connected to the piston rod. The hydraulic cylinder pulls the moving plate and the impact block on the moving plate through the piston rod. The blocking rod can block the movement of the impact block, separating the impact block from the moving plate. Under the action of gravity, the impact block falls from the discharging groove and falls from the blanking cylinder and the protective cylinder to impact the track link on the bearing plate. The movement of the moving plate can be restricted through the fixed groove, improving the stability of the moving plate driving the impact block during movement. The blocking rod blocks the movement of the impact block, enabling the impact block to automatically fall, so that the impact block impacts the track link on the bearing plate, and the impact resistance strength of the track link is analyzed and evaluated, providing data support for continuously improving the impact resistance strength of the track link.

[0015] An operation method for a track link impact strength test device is characterized in that the operation method includes the following steps:

[0016] First, check whether the circuit of the track link impact strength test device is normal, and check whether the drive motor and the hydraulic cylinder are working properly;

[0017] Second. Sleeve the mounting cylinder on the bearing plate onto the positioning post, and place the track link to be subjected to the impact strength test on the bearing plate;

[0018] Third. Start the hydraulic cylinder. The hydraulic cylinder pushes the moving plate to move in the feeding groove through the piston rod. After moving the moving plate to one end of the fixing groove, turn off the hydraulic cylinder, and place the impact block on the moving plate in the feeding groove;

[0019] Fourth. Start the drive motor. The drive motor drives the transmission stud to rotate. The transmission stud pushes the connecting screw barrel to rise or fall, driving the adjusting plate and the feeding plate on the adjusting plate to rise or fall. According to the impact resistance test method, rotate the adjusting stud through the handle to adjust the height of the corresponding feeding plate, so that multiple feeding plates are at the same or different heights;

[0020] Fifth. After the height of the adjusting plate is adjusted, rotate the protective cylinder on the blanking cylinder so that the fixing rod enters the through groove. Move the protective cylinder up and down on the blanking cylinder so that the bottom end of the protective cylinder covers the bearing plate. After the height of the protective cylinder is adjusted, rotate the protective cylinder so that the fixing rod enters the hanging groove;

[0021] Sixth. Start the hydraulic cylinder. The hydraulic cylinder pulls the moving plate and the impact block on the moving plate through the piston rod. The stop rod can block the movement of the impact block, separating the impact block from the moving plate. The gravity makes the impact block fall from the feeding groove and fall from the blanking cylinder and the protective cylinder to impact the track link on the bearing plate;

[0022] Seventh. Record the deformation of the track link impacted by the impact block, and analyze and evaluate the impact resistance strength of the track link;

[0023] Eighth. After the impact strength test of the track link is completed, turn off the drive motor and the hydraulic cylinder, clean the impurities generated during the impact process of the track link, and cut off the power supply.

[0024] Beneficial effects:

[0025] 1. The drive motor drives the transmission stud to rotate forward or backward. The transmission stud pushes the connecting screw barrel to rise or fall, driving the adjusting plate and the feeding plate on the adjusting plate to rise or fall. According to the impact resistance test method, rotate the adjusting stud through the handle to adjust the height of the corresponding feeding plate, so that multiple feeding plates are at the same or different heights, corresponding the loading structure to the blanking cylinder one by one, and it can impact the same track link with impact blocks of different weights or conduct the impact resistance strength test on different track links with the same impact block, enriching the test methods of the impact resistance strength;

[0026] 2. The hydraulic cylinder pulls the moving plate and the impact block on the moving plate through the piston rod. The stop rod can block the movement of the impact block, separating the impact block from the moving plate. The gravity makes the impact block fall from the feeding groove and fall from the blanking cylinder and the protective cylinder to impact the track link on the bearing plate;

[0027] 3. Rotate the protective cylinder on the blanking cylinder so that the fixed rod enters the through groove. Move the protective cylinder up and down on the blanking cylinder to make the bottom end of the protective cylinder cover the bearing plate. After the height of the protective cylinder is adjusted, rotate the protective cylinder to make the fixed rod enter the hanging groove, and cover the bearing plate through the protective cylinder, so as to prevent the impact block or the track link from splashing when the impact block impacts the track link, and improve the safety of the track link during the impact resistance test.

The impact block falls from the discharge chute under the action of gravity, and falls from the blanking cylinder and the protective cylinder to impact the chain track section on the bearing plate. Seventh, record the deformation of the chain track section when impacted by the impact block, and analyze and evaluate the impact strength of the chain track section; 8. After the impact strength test of the track segment is completed, turn off the drive motor and hydraulic cylinder, clean up the impurities generated during the impact of the track segment, and cut off the power supply.
