If the lower end of the gearbox box 9 and the turning mold 8 are positioned and the outline center of rotation and the outer circle of the upper end of the gearbox box 9 are not concentric, namely, the center of rotation of the upper end of the gearbox box 9 is offset once in any direction, when the left and right end positioning mechanisms 7 are clamped, the offset direction of the upper end of the gearbox box 9 is contacted with one of the positioning blocks 75, the spring 77 in the positioning block 75 is compressed, and meanwhile, the reaction force of the spring 77 can enable the outline center of the upper end phi 310 of the gearbox box 9 to move towards the center of rotation of the turning mold 8, so that the box offset adjustment is realized.
2) When the upper end of the gearbox body 9 locates the excircle phi 310+3mm:
at this time, no matter whether the center of the excircle of the upper end phi 310 of the gearbox body 9 is offset or not, after the left end positioning mechanism and the right end positioning mechanism clamp the gearbox body 9, the arc-shaped positioning surface 751 in the positioning block 75 is completely tightly attached to the upper end positioning excircle of the gearbox body 9, meanwhile, the spring 77 in the positioning block 75 is compressed, the 3mm gap between the positioning block 75 and the positioning groove 74 is eliminated, and the two end surfaces are attached.
3) When the upper end positioning outer circle of the gearbox body 9 is in a phi 310 plus or minus 3mm interval (two limit sizes are not included):
after the left end positioning mechanism 7 and the right end positioning mechanism 7 clamp the gearbox body 9, the positioning blocks 75 on the two sides can simultaneously hold the upper end positioning part of the gearbox body tightly, the center offset direction of the positioning excircle on the upper end of the gearbox body 9 can be subjected to the reverse elastic force action of the spring 77 with larger extrusion force, the forces in other directions are overcome, and the upper end positioning center of the gearbox body 9 is forced to move towards the rotation center direction of the car model 8.
