Bearing positioning device includes pedestal, fixing axle and bearing, and the U-shaped structure of pedestal, fixing axle is that twin shaft is placed in the upper of pedestal
End, the bearing are fixed in fixing axle, which is cross-compound arrangement；The tailstock positioning device includes tailstock fixed frame and determines
Hyte part, tailstock fix the tail end for being placed on piston rod, and positioning component is two-section type cylindrical structure.
Preferably, the friction pulley uses upper and lower fraction block structure, and the welding to adapt to various sizes of piston rod needs
It asks, material selection rubber, in order to preferably protect the surface of piston rod not to be worn.
The bearing, which is that twin shaft is alternate, is composed structure, and bearing passes through fixed axis connection, the setting of duplex bearing with pedestal
The piston rod for needing to weld can be preferably carried, while piston rod can be implemented to limit, is had a dual effect.
The positioning component is two-section type cylindrical structure, and big cylinder is inserted into piston rod, and small cylinder is fixed on tailstock,
The tail end of piston rod is play a part of to support and be limited, prevents piston rod from deviateing main spindle when rotated.
The beneficial effects of the utility model are：
（1）When welding, ultra-fine process for long piston rod can automatically be rotated by motor, it is possible to reduce friction improves product quality, no
It needs manually to rotate by hand again, reduces welding sequence, be greatly improved welding efficiency.
（2）It can be achieved to be accurately positioned ultra-fine process for long piston rod, improve the precision of welding, shorten weld interval.
