[0023] A slide groove 108 (for filling lubricant) is provided in one end surface of the strip support platform 103.
[0024] The slide 109 is provided in the slide groove 108 and is matched with the movable fixed platform 110.

[0026] The horizontal hydraulic cylinder 111 is provided with a transition connecting rod 112 fixedly connected to the dynamic fixed platform 110.
[0027] The cycloid pinwheel planetary reducer 113 to be tested is fixed with a transition shaft 116.
[0028] A first connecting plate 117 is provided on the transition shaft 116.
[0029] A second connecting plate 118 is fixedly connected to one side of the first connecting plate 117.
[0030] A transmission shaft 119 is provided on one side of the second connecting plate 118.
[0031] A vertical support plate 120 is provided between the fixed platform 104 and the slide 108.

[0033] The transmission shaft 119 passes through the bearing seat 121 and the torque sensor 125 and is connected to the input shaft 106;
[0034] Among them, the disc brake blocking device 105, the cycloid pinwheel planetary reducer 113 to be measured, and the power motor 114 are on the same plane symmetrical center line, and the horizontal hydraulic cylinder 111, the power motor 114, and the torque sensor 125 are respectively connected to the PLC controller 102.
[0035] The working principle is:
[0036] (1) Fix the cycloid pinwheel planetary reducer 113 to be measured on the dynamic fixed platform 110;
[0037] (2) The PLC controller 102 is used to start the horizontal hydraulic cylinder 111, so that the horizontal hydraulic cylinder 111 pushes the slider 109 in the slide groove 108 toward one side of the disc brake blocking device 105 through the transition connecting rod 112, and the cycloid pinwheel planetary reducer 113, power motor 114, and coupling 115 on the dynamic fixed platform 110 move horizontally synchronously;

[0039] (4) The PLC controller 102 is used to start the power motor 114. At this time, the power motor 114 is linked to the cycloid planetary reducer 113 under test through the coupling 115 to rotate synchronously.

After the test is completed, the PLC controller 102 is used to control the power motor 114 to stop;
[0040] (5) Perform the reset action of (2) and remove the cycloid pinwheel planetary reducer 113 under test from the movable fixed platform 110 of (1), thus completing the test operation.

[0043] Among them, the distance measuring sensor 128 is connected to the PLC controller 102, so that the PLC controller 102 presets the stroke range value for controlling the horizontal movement of the horizontal hydraulic cylinder 111. When controlling the horizontal reciprocating movement of the horizontal hydraulic cylinder 111, the distance measuring sensor 128 is combined with the PLC controller 102 to realize automatic and precise stroke control to meet the safety testing requirements.
