Embodiment Construction

[0011] As shown in Fig. 1 and Fig. 2, the present invention comprises: frame 1, stepper motor 2, headstock 3, lead screw 4, chuck seat 5, chuck 6, detection probe 8, probe seat 9, tailstock 10 . The head frame 3 is fixedly installed on the frame 1, the stepping motor 2 is fixedly installed on the head frame 3, and the chuck seat 5 is connected with the stepping motor 2 through the transmission mechanism on the head frame 3. The probe base 9 is installed on the frame 1, and the detection probe 8 is installed on the probe base 9. The detection probe 8 and the probe base 9 can move axially along the guide rail on the frame 1 as a whole, so that automatic detection can be realized. The tailstock 10 is installed on the frame 1 and can move axially along the guide rail on the frame 1 to detect crankshafts of different lengths. The crankshaft 7 to be tested is clamped on two chucks 6, and the chuck 6 can use the lead screw 4 on the chuck seat 5 to make precise radial movement along ...

Description

technical field [0001] The invention relates to a detection device for the fatigue life of components in the technical field of automobiles, in particular to a detection device for the remaining fatigue life of a decommissioned crankshaft of an automobile. Background technique [0002] At present, a large number of automobiles are scrapped every year in our country, and the decommissioned auto parts produced can reach millions of tons. In my country, the retired auto parts are generally recycled as scrap iron and steel. In developed countries such as Europe, the United States, and Japan, a considerable part of the retired auto parts flows to the aftermarket after remanufacturing, and has formed a huge auto parts recycling industry. manufacturing industry. Therefore, starting from the concept of sustainable development, the development of recycling and remanufacturing technology of decommissioned automobile parts is of great significance to energy saving, material saving, env...
