And it is generally aligned in the same plane；The through hole that the short pin corresponds to workpiece to be processed bottom is arranged on the center of the riser bottom, described
Riser side is provided with the stop pin；The center on the riser top is provided with mandrel, and the rear end of the mandrel is provided with screw thread；It is described
Pressing plate is provided with U-shaped opening groove, and the diameter of the mandrel is less than the width of the U-shaped opening groove, and the core sleeve is mounted in the pressure
In the U-shaped opening groove of plate and by nut check pressing plate, the workpiece to be processed is pressed on the flat bearing and nailed on.
Further, the flat bearing is followed closely not on the same line；
Further, the riser center upper portion is provided with through hole, and the front end of the mandrel inserts the through hole and is arranged on institute
State on riser；
Further, the front and rear of the bottom plate is respectively equipped with U-lag, and the bottom plate is coordinated by screw and the U-lag
On lathe；
Further, the back side of the bottom plate is provided with kidney slot, and the both ends of the kidney slot are fixed with by screw respectively
Positioning key；
Further, the another side for installing the positioning and clamping mechanism is provided with feeler block on the riser, institute
Feeler block is stated to be connected with the riser by screw.
After employing such structure, followed closely using flat bearing, stop pin, short to sell out into positioning, clamping is stable, and positioning is accurate
Really, precision is high, easy to operate；Be tod by three or more than three flat bearings nail limitation workpiece three degree of freedoms, using pressing plate
It is further that workpiece to be processed is fixed, the U-lag of the waist type groove of bottom plate and both sides is easy to fixture assembling preferably to limit its motion
Ensure that higher precision.
