The side of the arc frame 710 is fixedly connected to an extrusion block 713. When the arc frame 710 swings, the extrusion block 713 fixed on the side is driven to swing and squeeze the placement plate 73. The placement plate 73 shakes inside the placement table 71 through the spring telescopic rod 72, so that the relative pressure between the wear-resistant part and the friction block 67 can be increased, and the friction strength can be increased, which is greater than the conventional friction strength, so that a better product can be used in conventional use.

[0037] The use method and advantages of the present invention: When the alloyed medium manganese steel wear-resistant parts testing device is used, the working process is as follows:

[0038] When in use, first place the wear-resistant part on the surface of the placement plate 73 and clamp it with the clamping rod 74. The wear-resistant part will resist the friction block 67 and squeeze the spring telescopic rod 33 and the spline telescopic rod 65. After placement, start the drive motor 31. The drive motor 31 drives the gear 32 to rotate. After the gear 32 rotates, it drives the long gear 34 meshing on the side to rotate. The long gear 34 rotates through the spring telescopic rod 33. When the long gear 34 rotates, it drives the round rod 35 at the lower end to rotate. The rotation of the round rod 35 drives the eccentric wheel 61 to rotate. The rotation of the eccentric wheel 61 When the annular groove 62 on the lower surface is driven to rotate, the eccentric rotation of the annular groove 62 will squeeze or pull the connecting rod 1 63, and the connecting rod 1 63 drives the connecting rod 2 64 to move. The connecting rod 2 64 is limited by the limiting groove 66, so that the connecting rod 2 64 forms a rapid reciprocating motion, and the connecting rod 2 64 drives the friction block 67 at the lower end to move, so as to carry out the wear resistance test on the wear-resistant parts, and exert pressure on the friction parts through the downward pressure of the spring telescopic rod 33, so as to improve the friction strength and implement better detection. The friction force is greater than that in actual use to detect the optimal friction resistance strength of the test piece.

[0039] At the same time, when the outer rod 331 rotates, the tooth 36 is driven to rotate, and when the tooth 36 rotates, the bevel gear 39 meshing on the side is driven to rotate. The bevel gear 39 rotates through the rotating rod 38. When the rotating rod 38 rotates, it is transmitted to the rotating rod 1 44 through the transmission belt 45. When the rotating rod 1 44 rotates, it drives the side rotating wheel 46 to rotate inside the fixed shell 41. When the rotating wheel 46 rotates, it drives the gear rod 1 47 to rotate. Every time the rotating wheel 46 and the gear rod 1 47 rotate one circle, they will mesh with the gear 2 415 once and make the gear 2 415 rotate once. When the gear 2 415 rotates, it drives the meshing gear 1 410 to rotate. At one time, gear one 410 drives the ones digit of the digital wheel 49 fixed on the side to rotate once, and the digital wheel 49 is displayed through the numerical display hole 43 opened on the surface of the fixed shell 41. The ones digit digital wheel 49 rotates ten times, that is, one circle, and meshes with another gear two 415 through the gear rod two 412 on the other side, and when the other gear two 415 rotates, it drives the tens digit digital wheel 49 meshing with it to rotate once, and so on. Every time the gear 32 rotates one circle, the friction block 67 rubs back and forth once to count, thereby realizing automatic and convenient automatic counting, leaving digitized detection data for the wear-resistant parts.

[0040] After the detection is completed, it is only necessary to press the pressing rod 420, which drives the inclined surface block 419 to slide downward. The inclined surface block 419 will squeeze the cross bar 417 when sliding. When the cross bar 417 is squeezed, it will follow the inclined surface of the inclined surface block 419, driving the rectangular frame 414 to rotate counterclockwise with the torsion spring rod 413 as the center of the circle. At this time, the rectangular frame 414 drives the internal gear 2 415 to separate from the gear 1 410. At the same time, the triangular block 416 on the surface of the rectangular frame 414 will rotate upward and squeeze the peach-shaped block 411 on the side of each number wheel 49. When the peach-shaped block 411 is squeezed, the bottom is matched with the triangular block 416, so that the tip of each peach-shaped block 411 is upward, and all the number wheels 49 will be driven to return to zero, so that the next wear-resistant detection can be carried out.

[0041] At the same time, when the friction block 67 detects the wear-resistant parts, the wear-resistant parts will gradually be rubbed off, and the initial height will gradually decrease. When the wear-resistant parts gradually decrease, the inner rod 333 drives the long gear 34 to gradually decrease through the spring 332, thereby driving the friction block 67 to decrease, and the friction block 67 will always maintain a fit with the wear-resistant parts. At the same time, the spline telescopic rod 65 on the other side decreases synchronously with it. When the inner rod 333 decreases, it drives the L-shaped rod 52 in the surface annular groove 51 to decrease at the same time. The L-shaped rod 52 drives the recording rod 53 at the other end to decrease at the same time inside the fixed shell 41, and the descending height is displayed through the scale display frame 42 on the surface of the fixed shell 41, so as to detect the comprehensive value of the number of frictions and the descending height, so as to improve the wear-resistant parts.

[0042] When the eccentric wheel 61 rotates, it drives the rotating rod 75 at the lower end to rotate at the same time. When the rotating rod 75 rotates, it drives the small gear 76 on the surface to rotate. The small gear 76 drives the bevel gear 1 78 meshing on the side to rotate. The bevel gear 1 78 rotates through the rotating rod 2 77. When the rotating rod 2 77 rotates, it drives the inclined rod 711 fixed on the other side to rotate. When the inclined rod 711 rotates, it drives the slider 712 on one side to rotate inside the arc frame 710. When the arc frame 710 is squeezed by the slider 712, it will swing up and down with one end of the support rod 79 as the center of the circle. When the arc frame 710 swings, it drives the extrusion block 713 fixed on the side to swing and squeeze the placement plate 73. The placement plate 73 shakes inside the placement table 71 through the spring telescopic rod 1 72. In this way, the relative pressure between the wear-resistant part and the friction block 67 can be increased, and the friction strength can be increased. The friction strength is greater than that of the conventional one. In this way, a better product can be used in conventional use.
