[0062] This embodiment also discloses a camshaft turning process, which uses the above-mentioned camshaft turning machine tool and includes the following steps:

[0063] When the metal rod is initially processed, the movable sliding block 202 drives the fixed chuck 204 to move, so that the central axis of the fixed chuck 204 coincides with the central axis of the rotating chuck 102, and the lifting and squeezing plate 203 moves downward to squeeze the fixed mounting plate 201, so that the position of the movable sliding block 202 is fixed, and the fixed chuck 204 fixes the two ends of the metal rod respectively. The rotating chuck 102 rotates, and the lathe body 1 performs preliminary processing on the metal rod, so that the camshaft is initially formed;

[0064] When the camshaft is processed again, the movable mounting plate 301 drives the lower fixed blocking rod 401 to move, so that the lower fixed blocking rod moves toward the fixed mounting plate 201, and the bottom surface of the fixed mounting plate 201 contacts the top surface of the lower fixed blocking rod 401. During the movement of the lower fixed blocking rod 401, the fixed mounting plate 201 contacts and squeezes the moving blocking block 403, so that the moving blocking block 403 moves. The movable plate can make the moving blocking rod 404 move toward the fixed mounting plate 201, and the bottom surface of the moving blocking rod 404 contacts the top surface of the fixed mounting plate 201. Contact, the lower fixed stop rod 401 and the movable stop rod 404 limit and fix the fixed mounting plate 201. After the fixing is completed, the lifting and squeezing plate 203 moves upward to release the fixation of the movable sliding block 202. The movable sliding blocks 202 of the two sets of fixed components 2 move synchronously to change the position of the central axis of the camshaft. The lifting and squeezing plate 203 moves downward to re-fix the position of the movable sliding block 202. After the fixing is completed, the movable mounting plate 301 moves to release the limit fixation of the fixed mounting plate 201, and the lathe body 1 processes the cam of the camshaft.
