Art problem.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of Auxiliary support floating hold-down mechanisms, are intended to pressure of floating
Tight position of the thin-wall part away from master positioning face, and then ensure machining accuracy.
The technical solution of the utility model is as follows：A kind of Auxiliary support floating hold-down mechanism, it is characterised in that：Including positioning
(1) and floating compact heap (7) are sold, auxiliary clamp cylinder (2) is wherein equipped with beside positioning pin (1), is equipped with above the auxiliary clamp cylinder
Briquetting (3) is aided in, is connected in the middle part of the auxiliary briquetting by link block (4) with auxiliary clamp cylinder (2) top, and link block (4)
Both ends are respectively hinged by connecting pin (5) and corresponding auxiliary clamp cylinder (2) and auxiliary briquetting (3)；The auxiliary briquetting (3)
One end be hinged by axis pin (6) and the piston rod upper end of auxiliary clamp cylinder (2), axis pin (6) is parallel with connecting pin (5), described
So that the other end of auxiliary briquetting (3) can above and below be swung around the axis pin (6)；The end of described auxiliary briquetting (3) other end is
U-shaped breach (3a), the U-shaped breach is through the top and bottom for aiding in briquetting (3), and the connection side of U-shaped breach (3a) is equipped with
One limiting groove；The floating compact heap (7) is located in U-shaped breach (3a), which compresses rotation axis (8) and the institute at middle part
State that connecting pin (5) is parallel, and the both ends of rotation axis (8) are rotatably assorted with the U-shaped breach (3a) two sides；Described float compresses
In the limiting groove of one end insertion U-shaped breach (3a) of block (7), and put above and below by limiting groove limitation floating compact heap (7)
Dynamic amplitude, the bottom surface of floating compact heap (7) other end are installed with pressure head (9).
In said structure, positioning pin (1) carries out auxiliary positioning, auxiliary clamp cylinder to position of the workpiece away from master positioning face
(2) act when other end with dynamic auxiliary briquetting (3) can around axis pin (6) above and below swing, and auxiliary briquetting (3) the other end to
During lower swing, pass through pressure head (9) workpiece pressing；Since pressure head (9) is located on floating compact heap (7), thus make pressure head (9)
It lags than auxiliary briquetting (3) during upper and lower swing, so as to achieve the purpose that compression of floating, avoids because pressing force is excessive
And thin-wall part is deformed, it prevents workpiece and is scrapped because deformation is compressed；Also, position of the floating workpiece pressing away from master positioning face
Afterwards, it can prevent from rocking during tool sharpening, so not only can guarantee machining accuracy, but also can guarantee cutting-tool's used life, so as to very
Solves the defects of prior art well.
Preferably, the pressure head (9) is cylindrical structural, material is black nylon.
Preferably, the positioning pin (1) uses rhombus pin.
Advantageous effect：The positioning pin of the utility model carries out auxiliary positioning, auxiliary to position of the workpiece away from master positioning face
The other end with dynamic auxiliary briquetting can above and below be swung around axis pin when clamping cylinder acts, and aid in the other end of briquetting to lower swing
When, pass through pressure head workpiece pressing；Since pressure head is located on floating compact heap, pressure head is thus made to compare during swinging above and below
Briquetting hysteresis is aided in, is compressed so as to achieve the purpose that float, is avoided deforming thin-wall part because pressing force is excessive, prevent workpiece
It is scrapped because deformation is compressed；Also, behind position of the floating workpiece pressing away from master positioning face, it can prevent from shaking during tool sharpening
It is dynamic, it so not only can guarantee machining accuracy, but also can guarantee cutting-tool's used life, so as to well solve lacking for the prior art
It falls into.
