[0022] Reference Figure 1The bicycle trainer power speed testing machine of the embodiment comprises a rack 1, a test bin 2 fixedly connected to the top plate of the rack 1, a detection mechanism arranged in the test bin 2 for testing the product to be tested, a fixed plate 3 horizontally fixedly connected to the side wall of the rack 1, a plurality of support plates 4 fixedly connected to the top of the fixed plate 3, a first mounting seat 5 and a second mounting seat 7 fixedly arranged on the side edge of the top of the fixed plate 3 away from the test bin 2, a first clamping assembly 6 arranged on the top of the first mounting seat 5 for fixing the bottom of the product to be tested, a third mounting seat 8 horizontally fixedly connected to the top of the side wall of the second mounting seat 7 away from the test bin 2, a second clamping assembly 9 arranged on the top of the third mounting seat 8 for fixing the axial direction of the product to be tested, a top rod 10 fixedly connected to the clamping end of the second clamping assembly 9, and the other end of the top rod 10 penetrating through the second mounting seat 7 and being in sliding connection with the second mounting seat 7; the first clamping assembly 6 is a compression clamp, and the second clamping assembly 9 is a push-pull type quick clamp; the detection mechanism comprises a motor 11 fixedly connected to the inner bottom of the test bin 2, a first coupling 12 detachably connected to the rotating shaft of the motor 11, a sensor 13 detachably connected to the other end of the first coupling 12 for detecting the power, speed, torque and other parameters of the product to be tested, a second coupling 15 detachably connected to the other end of the sensor 13, a transmission shaft 17 detachably connected to the other end of the second coupling 15, the other end of the transmission shaft 17 extending to the outside of the test bin 2, and a third coupling 16 connected to the other end of the transmission shaft 17; the rotating shaft of the motor 11 is coaxially arranged with the sensor 13, the transmission shaft 17 and the top rod 10. When detecting, the product to be tested is placed on the top of the fixed plate 3, is limited by the support plates 4 on the top of the fixed plate 3, and then the third coupling 16 connected to the outer end of the transmission shaft 17 is connected to the rotating shaft of the product to be tested, so that the product to be tested is in the testing station. At this time, the first clamping assembly 6 is closed to fix the bottom of the product to be tested, and then the second clamping assembly 9 is closed. When the second clamping assembly 9 is closed, the other end of the top rod 10 is driven to move to the direction of the rotating shaft of the product to be tested until the other end of the top rod 10 abuts against the outer wall of the product to be tested, so as to fix the axial direction of the rotating shaft of the product to be tested, thereby avoiding the rotating shaft of the product to be tested and the transmission shaft 17 from being deflected during testing, and affecting the test result. Then the motor 11 is started, so that the first coupling 12 drives the rotating mechanism in the sensor 13 connected thereto to rotate. When the rotating mechanism in the sensor 13 rotates, the second coupling 15 and the transmission shaft 17 are driven to start rotating.
