Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model as shown in Figure 1, 2; a crankshaft straight dimension protector for glow discharge nitriding, is made up of right handed screw base 1, right handed screw 2, dextrorotation inner bolt hole 3, adjustment handle 4, left-handed inner bolt hole 5, left-handed screw 6, push rod first 7, cone-shaped ejecting block first 8, sensor jacking block 9, pressure transmitter 10, left-handed screw base 11, cone-shaped ejecting block second 12, push rod second 13, wire 14, controller 15, adjusting nut 16, balance weight for crankshaft 17, crankpin 18.
Described right handed screw 2 and the dextrorotation inner bolt hole 3 in adjusting nut 16 partner right-hand thread pair, and left-handed screw 6 and the left-handed inner bolt hole 5 in adjusting nut 16 partner left hand thread pair, and adjustment handle 4 is integrally welded with adjusting nut 16; Before glow discharge nitriding; the crankshaft straight dimension protector of glow discharge nitriding is placed between two balance weight for crankshafts 17; by operation adjustment handle 4, adjusting nut 16 is rotated; right handed screw 2 moves right; right handed screw base 1 is driven to move right; left-handed screw 6 is moved to the left, and drive left-handed screw base 11 to be moved to the left, the crankshaft straight dimension protector of glow discharge nitriding is just fixed between two balance weight for crankshafts 17.
