Working principle:
The auxiliary support mechanism of the utility model includes the supporting mechanism being connected being articulated in rotational handle 2, branch
Support mechanism is made of Auxiliary support module 3 and coupling bar 4, since when rotational handle 2 is rotated around rotary shaft 21, a part couples
4 tension of bar, a part of coupling bar 4 are pressurized, and therefore, Auxiliary support module 3 is during installation it should be noted that direction, in the present embodiment,
As shown in Figure 1, the supporting mechanism tension of left upper portion, and left lower and the supporting mechanism on right side are pressurized.
When supporting workpiece, workpiece is put on auxiliary support mechanism, is gently pushed down with pressing plate, it is then upward by handle 52
The positioning pin 51 for pulling up position-limit mechanism makes triangle double wedge 54a phase of the locating convex block 51a of 51 lower end of positioning pin with limited block 54
It is detached from, rotational handle 2 is enable to be freely rotated;Then rotary motion handle 2, by rotational handle 2 by coupling bar 4 with dynamic auxiliary
The screw rod 35 of supporting module 3 is mobile, when rotational handle 2, each supporting mechanism linkage work.Screw rod 35 draws or presses, and compresses bullet
While spring 36, by the cooperation on 34 inclined-plane of lower wedge block and upper 33 inclined-plane of voussoir, increase voussoir 33, to make to be fixed on
33 upper support 32 of voussoir rises, and forms rigid support to workpiece.
Since spring 36 is compressed, the elastic force of spring 36 generates pretightning force to voussoir, when mgsin θ=μm gcos θ (sliding force
=frictional force) when reach equalization point, θ is the inclination angle on voussoir inclined-plane, and μ is coefficient of friction, as long as meeting μ >=tan θ, vertical direction
Add multiple pressure power again, without sliding between upper voussoir 33 and lower wedge block 34, to be formed self-locking.Self-locking function can be avoided
Adjusting repeatedly between each Auxiliary support module 3, can greatly improve working efficiency.
The most preferred embodiment of the utility model has illustrated, the various change or remodeling made by those of ordinary skill in the art
All without departing from the scope of the utility model.
