[0031] The locking rack seat 7 is fixed to the bottom of the translation seat 5 by bolts.

[0032] The installation channel 12 and the installation groove 11 are vertically connected.

[0033] A small rack 15 is provided on the inner surface of the locking rack seat 7 , and the small rack 15 is meshed with the large rack 6 in an upper and lower manner.

[0034] The sum of the extended length of the cylinder and the length of the large rack is smaller than the distance between the first side plate and the second side plate.

[0035] The working principle of this utility model is:

[0036] Whenever the crankshaft processing production line produces the next crankshaft of a certain length, the worker needs to adjust the position of the rotating shaft 4 (translation seat 5, rotating motor 3) of the utility model so that the rotating shaft 4 can clamp and support the crankshaft after it moves into place during production. When the worker adjusts the position of the rotating shaft 4, the worker needs to loosen the bolts first. Due to gravity, the locking rack seat 7 moves downward, the small rack 15 is disengaged from the large rack 6, and the locking rack seat 7 does not lock the large rack 6. The worker starts the cylinders of the two crankshaft supporting rotating devices, and the cylinder 2 drives their respective large racks 6, translation seat 5, rotating motor and rotating The shaft 4 moves forward, and the rotating shafts 4 of the two crankshaft-supported rotating devices slide toward each other. The cylinder 2 is in an extended state. The worker places the crankshaft between the rotating shafts 4 of the two crankshaft-supported rotating devices. The worker then pushes the translation seats 5 of the two crankshaft-supported rotating devices to slide toward each other. The two rotating shafts just clamp the crankshaft. Then the worker keeps the translation seat 5 stationary, and then installs the locking rack seat 7 into the mounting groove 11. The small rack engages with the large rack 6, and the locking rack seat 7 locks the large rack 6. After that, the extension stroke of the cylinder can accurately clamp the crankshaft, thereby realizing the adjustment of the position of the rotating shaft 4, and the adjustment is very convenient.
