Technical Field
The utility model relates to an auxiliary stay and tight aggregate unit of clamp belongs to machining, lathe metal processing equipment's manufacturing and application, and the location that is applicable to light-duty thin wall blank work piece is tight.
Background
In the precision machining process of a machine tool, the positioning and clamping requirements on the light thin-wall blank workpiece are higher, and if the positioning rigidity, stability and reliability of the positioning reference surface of the workpiece need to be improved, an auxiliary support can be selected for auxiliary positioning. The auxiliary supports are similar in form to the adjustable supports, but they function differently, they need to be readjusted for each workpiece, do not function as a positioning function, and must be engaged after the workpiece is placed on the main support. The auxiliary support is used for increasing the rigidity of a workpiece, the rigidity of a clamp and pre-positioning of the workpiece, and is sometimes used for bearing the gravity, clamping force or cutting force of the workpiece. Although the auxiliary support does not play a role in limiting the degree of freedom of the workpiece, the defects that the clamping force is not perpendicular to the main positioning base plane, the machining plane is far away from a part with good rigidity of the workpiece and the like can be overcome. Typical auxiliary support structures (e.g., screw, self-aligning, push-pull, etc.) require readjustment of the support point height each time due to manufacturing tolerances of the workpiece blanks, which is time consuming and labor intensive.

And the auxiliary support mounting seat and the pressing oil cylinder are fixed on the clamp mounting plate. The supporting rod, the automatic ejector pin, the pressure spring, the clamping rod and the limiting block are arranged in the auxiliary support mounting seat. The upper end of the supporting rod is provided with a tooth surface supporting bolt which is a spherical adjustable sawtooth-shaped supporting nail, so that the friction coefficient can be increased, and the workpiece is prevented from moving after being stressed. The lower end of the supporting rod is connected with a pressure spring, and the position of the supporting rod is automatically adjusted by the pressure spring. The limiting block is arranged at the lower part of the supporting rod and is used for limiting the movement amount of the supporting rod upwards and ensuring that the inclined plane at the lower end of the supporting rod is reliably contacted with the automatic ejector pin.
