The processing of other faces, this mode for repeatedly being positioned again clamping is time-consuming and laborious, and labor intensity is big, and processing efficiency is low,
Especially in batch production, production efficiency is greatly reduced.
Utility model content：
The purpose of this utility model is to provide a kind of convenient for clamping and the high part lasso special fixture of production efficiency.
The utility model is implemented by following technical solution：A kind of part lasso special fixture comprising pedestal, pressing plate, spiral shell
Column, scroll chuck；It is fixed with the scroll chuck in the base top, is coaxially fixed in the centre bore of the scroll chuck
There is the stud, is slided up and down outside the stud above the scroll chuck and be arranged with the pressing plate, in the pressing plate
Nut is bolted on the stud of top, the nut is contacted with the pressing plate top movable.
Further, the pedestal includes the fixed plate being fixedly connected sequentially from bottom to top, supporting leg and mounting plate, and described three
Dog chuck is movably arranged on the top of the mounting plate, and the centre bore with the scroll chuck is offered in the middle part of the mounting plate
It is connected to the through-hole of setting；Interference is equipped with chuck fixed pin in the centre bore of the scroll chuck, in the chuck fixed pin
Bottom end is coaxially fixed with spacer pin, and the spacer pin activity is plugged in the through-hole；It is bolted in the bottom end of the spacer pin
Fixing bolt, the bolt outer cover between the nut and the mounting plate of the fixing bolt are equipped with snap-gauge, the card
Plate top and the mounting plate movable contact；The stud is studs, the bottom end of the stud and the chuck fixed pin
Top be spirally connected.
Further, it is provided with horizontally disposed positioning plate on the mounting plate around the scroll chuck, in institute
It states positioning plate top vertical and is plugged with positioning pin.
The advantages of the utility model：The utility model realizes quick positioning to machined part by scroll chuck and positioning pin
And the clamping of horizontal direction, then stud, pressing plate and nut by being connected on the clamp body are to machined part in vertical direction
On be clamped, which keeps each machined surface of workpiece to be added unobstructed, and clamped one time can be completed to each machined surface
Processing is not necessarily to resetting and clamping, significantly improves processing efficiency, which is simple and convenient to operate, and mitigates work significantly
The labor intensity of people.
Description of the drawings：
Fig. 1 is the overall structure sectional view of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Reference numeral in figure is：Fixed plate 1, mounting hole 2, fixing bolt 3, supporting leg 4, mounting plate 5, chuck fixed pin 6,
Positioning plate 7, positioning pin 8, pressing plate 9, stud 10, nut 11, scroll chuck 12, snap-gauge 13, through-hole 14, workpiece to be added 15, limit
Pin 16, pedestal 17.
Specific implementation mode：
As shown in Figure 1 and Figure 2, a kind of part lasso special fixture comprising pedestal 17, pressing plate 9, stud 10, scroll chuck
12；Pedestal 17 includes fixed plate 1, supporting leg 4 and the mounting plate 5 being fixedly connected sequentially from bottom to top, 12 activity setting of scroll chuck
At the top of mounting plate 5, the through-hole 14 that setting is connected to the centre bore of scroll chuck 12 is offered at 5 middle part of mounting plate；Three
Interference is equipped with chuck fixed pin 6 in the centre bore of dog chuck 12, and spacer pin 16 is coaxially fixed in 6 bottom end of chuck fixed pin,
16 activity of spacer pin is plugged in through-hole 14；It is bolted with fixing bolt 3 in the bottom end of spacer pin 16, in the nut of fixing bolt 3
3 outer cover of fixing bolt between mounting plate 5 is equipped with snap-gauge 13,13 top of snap-gauge and 5 movable contact of mounting plate, fixing bolt
3 nut is connected to the bottom of snap-gauge 13；Stud 10 is studs, the bottom end of stud 10 and the top spiral shell of chuck fixed pin 6
It connects, is slided up and down outside the stud 10 above scroll chuck 12 and be arranged with pressing plate 9, be spirally connected on the stud 10 above pressing plate 9
There are nut 11, nut 11 to be contacted with 9 top movable of pressing plate；It is provided on mounting plate 5 around scroll chuck 12 horizontally disposed
Positioning plate 7, be plugged with positioning pin 8 in 7 top vertical of positioning plate, scroll chuck 12 15 carries out positioning clamping to machined part,
15 movement in the horizontal direction of workpiece to be added is limited, by the cooperation of positioning pin 8 and 15 upper Positioning holes of workpiece to be added, limitation is to be added
