Description

Technical Field

[0001] The utility model relates to the technical field of friction and wear testing, and particularly relates to a loading device for studying the impact-sliding coupled wear test of materials. Background Art

[0002] In the engineering field, many mechanical components are often subjected to complex impact and sliding wear during actual operation, such as bearings, rails and wheels of rail transit systems, and gear transmissions of construction machinery. Under the coupled action of impact or sliding wear, the service life of these components is significantly reduced, and more frequent maintenance and replacement are required, increasing the maintenance cost and downtime. Especially for some key components, their damage may cause the entire system to shut down, resulting in production interruption and economic losses. There are various types of wear involved under the impact-sliding coupled action, and the wear mechanism is complex. It is necessary to explore the mechanism through experiments to provide important references for material design and engineering applications. However, most of the current wear test devices are of a single wear mode. For example, in the patent CN 219590124U, an impact wear test device only studies the wear behavior of materials under impact loads. Another example is the patent CN 220455098U, a multi-functional friction and wear test device, which can only study the sliding wear behavior between friction pair A and friction pair B. Therefore, the existing wear test devices have a single function, and when studying impact and sliding wear, the material needs to be disassembled and replaced on another test device midway, which brings inconvenience to the wear test.

[0003] Therefore, the existing technology still needs to be improved. Summary of the Utility Model

[0034] In this embodiment, the loading device for studying the impact-sliding coupled wear test of materials includes a top plate 1, a slider 2, a driving component 3, a connecting block 4, an electromagnetic coil 5, an impact rod 6, a base 7, and a console 9. Among them, the slider 2 is slidably arranged on the bottom side of the top plate 1, the driving component 3 is arranged on the top plate 1, and one end of the driving component 3 is connected to the slider 2 to drive the slider 2 to slide on the top plate 1. The connecting block 4 is arranged on the bottom side of the slider 2, and the connecting block 4 and the slider 2 can be detachably connected by screws 15. A vertically distributed groove 401 is provided on the bottom side of the connecting block 4, the electromagnetic coil is vertically arranged on the inner wall of the groove 401, and the inner wall of the groove 401 is coated with an insulating layer (not shown). The top end of the impact rod 6 vertically passes through the electromagnetic coil 5 and is vertically movably arranged in the groove 401. There is a gap between the impact rod 6 and the electromagnetic coil 5, and the two do not contact each other. The bottom end of the impact rod 6 is used to fix the experimental material 8. The base 7 is arranged directly below the bottom end of the impact rod 6 and is used to wear the experimental material 8. The console 9 is arranged on the connecting block 4, and the driving component 3 and the electromagnetic coil 5 are respectively connected to the console 9. When the driving component 3 is started through the console 9, the driving component 3 can drive the slider 2, the connecting block 4, and the impact rod 6 to move, so that the experimental material 8 at the bottom end of the impact rod 6 moves horizontally on the base 7 for wear, and the sliding wear experiment is started.

It can also drive the impact rod 6 to move up and down by the electromotive force generated by the electromagnetic coil, so that the impact rod 6 drives the experimental material 8 to perform impact wear on the base 7. Therefore, the loading device for studying the impact-sliding coupled wear test of materials provided by the utility model can simultaneously make the experimental material 8 perform a sliding wear experiment and an impact wear experiment, which brings convenience to the research of the wear experiment.

[0035] As a further solution, a chute 101 is provided on the bottom side of the top plate 1, and a clamping block 201 is provided on the top side of the slider 2. The clamping block 201 is slidably arranged in the chute 101. Specifically, the slider 2 slides on the top plate 1 through the cooperation of the clamping block 201 and the chute 101, and stoppers (not shown) can be arranged at both ends of the chute 101 to limit the clamping block 201 to prevent the clamping block 201 from disengaging from the chute 101.

[0036] As a further solution, the driving assembly 3 includes a driving member 301 and a connecting rod 302. The driving member 301 is arranged on the top plate 1. One end of the connecting rod 302 is connected to the driving member 301, and the other end is connected to the slider 2. The driving member 301 drives the slider 2 to slide through the connecting rod 302. Specifically, the driving member 301 can be a cylinder or a lead screw motor. When the driving member 301 is a cylinder, the other end of the connecting rod 302 is fixedly connected to the slider 2. When the driving member 301 is a lead screw motor, the other end of the connecting rod 302 is provided with an external thread section (not shown), and a threaded hole (not shown) is provided on the slider 2. At this time, the other end of the connecting rod 302 is threadedly connected to the threaded hole of the slider 2.

[0037] In this embodiment, a spring 10 is provided on the top side in the groove 401. The bottom end of the spring 10 is connected to the top end face of the impact rod 6. The spring 10 is used to fix the impact rod 6 so that the impact rod 6 can move up and down.

[0038] As a further solution, a limiting protrusion 402 is provided on the inner wall of the groove 401. A guiding groove 601 distributed vertically is provided on the side wall of the impact rod 6. One end of the limiting protrusion 402 is arranged in the guiding groove 601. Specifically, the guiding groove 601 is used to guide the impact rod 6. Through the lateral abutment of the limiting protrusion 402, the impact rod 6 can only move up and down vertically and cannot swing horizontally.

[0039] As a further solution, a first knob 11 is provided on the console 9. The first knob 11 is electrically connected to the console 9 and is used to adjust the moving speed of the driving assembly 3 driving the slider 2. When the driving member 301 is a cylinder, the air intake of the cylinder can be adjusted through the first knob 11. When the driving member 301 is a lead screw motor, the current magnitude of the lead screw motor can be adjusted through the first knob 11 to control the rotation speed of the connecting rod 302.

[0040] In this embodiment, a pressure sensor 12 is provided on the base 7. The pressure sensor 12 is electrically connected to the console 9 and is used to sense the impact load of the experimental material 8. Specifically, since the spring 10 is connected to the impact rod 6, it is not necessarily accurate to judge the impact load according to the magnitude of the current passing through the electromagnetic coil 5. When the impact rod 6 moves downward, the elastic force of the spring 10 will affect the impact force on the impact rod 6. Therefore, the impact load applied by the experimental material 8 is sensed through the pressure sensor 12 to make the experimental data more accurate.

[0041] As a further solution, a second knob 13 is provided on the console 9. The second knob 13 is electrically connected to the console 9 and is used to adjust the current magnitude of the electromagnetic coil 5. By adjusting the current magnitude of the electromagnetic coil 5, the electromotive force is changed, thereby changing the impact load of the impact rod 6.

[0042] As an even further solution, a display 14 is provided on the console 9. The display 14 is electrically connected to the console 9. The display 14 is used to display the intake air volume of the air cylinder, or the current value passed through the lead screw motor, and the impact load value sensed by the pressure sensor 12.

[0043] In this embodiment, a screw 15 is provided on the bottom end face of the impact rod 6. The screw 15 is used to fix the experimental material 8. Specifically, the experimental material 8 is provided with a through hole (not shown). The tail end of the screw 15 passes through the through hole and extends into the bottom end of the impact rod 6 for threaded connection, and the head end of the screw 15 locks the experimental material 8 to the bottom end of the impact rod 6.
