DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] As attached Figure 1 -Attached Figure 8 As shown, a motion shaft wear testing device includes a test cylinder body 1 and a drive motor 2. A motion shaft 22 is passed through the test cylinder body 1. The portion of the motion shaft 22 located in the test cylinder body 1 is installed with a stirring ring 15. The motion shaft 22 can move axially and rotate around the axial direction in the test cylinder body 1. One end of the motion shaft 22 is connected to a fixed sleeve 3, and the side of the fixed sleeve 3 away from the motion shaft 22 is connected to a connecting rod 11. The drive motor 2 is driven by a rotating disk 4, and the rotating disk 4 and the connecting rod 11 are connected by a connecting piece. By changing the connection method of the connecting piece, the drive motor 2 can drive the motion shaft 22 to rotate or move in the test cylinder body 1, thereby completing the circumferential wear test or axial wear test of the motion shaft 22.

[0026] A mounting sleeve 20 is connected to the side of the rotating disk 4 away from the T-slot 5. A socket 21 is provided in the mounting sleeve 20. The motor shaft of the drive motor 2 is inserted into the socket 21 for fixation, so that the drive motor 2 can drive the rotating disk 4 to rotate. The drive motor 2 is a servo motor and can adjust the speed.

[0027] The rotating disk 4 is provided with a T-slot 5. The connecting member includes a sliding block 6 that slides within the T-slot 5. Connecting rod 1 7 is connected to the sliding block 6. Connecting rod 1 7 extends beyond the T-slot 5 and has a fixing hole 8 defined in the portion of the connecting rod 7 located outside the T-slot 5. Connecting rod 2 11 is provided with mounting holes 12 and 13. The connecting member also includes a fixing pin 14 and the sliding block 6. Both ends of the sliding block 6 have through-holes 10 defined therein.

[0028] When performing a circumferential wear test on the motion shaft 22, the connecting block 9 is not required. The fixing pin 14 passes through the fixing hole 8 on the connecting rod 1 7 and the mounting hole 12 or the mounting hole 2 13 on the connecting rod 2 11, thereby securing the connecting rod 2 11 and the connecting rod 1 7 relative to each other. The sliding block 6 is maintained in the center of the T-slot 5. The rotating disk 4 then rotates, driving the motion shaft 22 within the test cylinder 1 via the sliding block 6, connecting rod 1 7, connecting rod 2 11, and fixing sleeve 3.

[0029] When testing the axial wear of the moving shaft 22, slide block 6 is moved away from the center of the rotating disk 4 to an eccentric position. Connecting rod 1 7 is passed through one through-hole 10 of connecting block 9. Fixing pin 14 then passes through another through-hole 10 of connecting block 9, mounting holes 12 and 13 of connecting rod 2 11, and then connects connecting rod 2 11 to connecting rod 1 7 via connecting block 9. At this point, rotating disk 4 rotates, driving the moving shaft 22 in axial reciprocating motion via connecting rod 1 7, connecting block 9, and connecting rod 2 11.

[0030] T-slot 5 is provided with positioning hole 18 and positioning hole 2 19. Positioning hole 18 is located at the center of rotating disk 4, and positioning hole 2 19 is a certain distance away from positioning hole 18. Positioning hole 18 and positioning hole 2 19 both extend through the bottom surface of T-slot 5 and rotating disk 4. Sliding block 6 has a threaded hole 17 on the side facing away from connecting rod 1 7. During circumferential wear testing, a bolt is threaded through positioning hole 18 and into threaded hole 17 to secure sliding block 6. During axial wear testing, a bolt is threaded through positioning hole 2 19 and into threaded hole 17 to secure sliding block 6.

[0031] Two sealing rings 16 are provided in the test cylinder 1. The sealing rings 16 are located at the connection between the test cylinder 1 and the moving shaft 22 to achieve a sealing effect.

[0032] The test cylinder 1 is equipped with a pressure supply port 23, a pressure measuring port 24, an exhaust port 25, a sand injection port 26, and a turbidity test port 27. The pressure supply port 23 is connected to an external water pump, and the pressure measuring port 24 is connected to a pressure measuring mechanism. The external water pump supplies pressure through the pressure supply port 23, providing different pressures to test whether the different pressures affect the moving axis.

[0033] The exhaust hole 25 exhausts air to prevent the presence of air inside from causing inaccurate measurement data and affecting the test results.

[0034] Sand of different particle sizes was added through the sand adding hole 26 to test the effect of sand of different particle sizes on the wear of the moving shaft. At the same time, solutions of different turbidities were prepared by adding sand to test the effect of solutions of different turbidities on the moving shaft.

[0035] The motion shaft drives the stirring ring 15 to stir the solution in the test cylinder 1, ensuring uniform mixing. The turbidity test port 27 is connected to the turbidity test mechanism, which is used to measure the turbidity of the solution in the test cylinder 1. When the turbidity reaches the set value, a signal is transmitted, the sand injection port 26 is closed, the pressure supply port 23 is pressurized, and the drive motor 92 reaches the set speed to perform the test.

[0036] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
