It marks closely；
The bottom base plate is equipped with drop-down drive cylinder and lower platen, the lower platen are movably installed with lower support base,
It is connected between the lower support base and the lower platen by second back-moving spring, the piston rod end for pushing drive cylinder
Lower crimp head is installed, the pushing fitting end abuts the lower platen, is equipped with lower pulling shaft, the bottom on the lower platen
It is provided with the through slot with the lower pulling shaft cooperation on plate, passes through the through slot at the top of the lower pulling shaft, the lower pulling shaft is corresponding
The V-arrangement positioning plate arrangement；
The lower platen is T-shaped plate, the horizontal part rear end of the T-shaped plate be provided with the card slot of the lower crimp head cooperation,
Horizontal part front end two sides are provided with blind hole, and the second back-moving spring is installed in the blind hole, and longitudinal portion of the T-shaped plate protrudes into
In the guide groove of the lower support base.
After the fixture of the utility model, the part processed will be needed to be placed in locating support, bottom is supported in lower fixed
Position pin, upper end are compressed by upper pressing pin, and side is positioned by the support of oil cylinder shoring and V-arrangement positioning plate, easily realize part
Stable position and fixation, improve part passing rate of processing.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 be in Fig. 1 A-A to cutaway view Amplified image；
Fig. 3 is B-B direction cutaway view Amplified image in Fig. 1；
