Energy fast positioning clamping fixes workpiece, and clamping force size can be controlled to deform and position with workpiece in reduction clamping process and missed
Difference, so as to improve the machining accuracy of part and processing efficiency.
Technical scheme is used by the utility model solves its technical problem：It is described to be used for Digit Control Machine Tool spring sliding pin pressure
Clamper is by chuck body, bottom supporting nail and vacuum suction component, short side side supporting plate and spring sliding pin component, long side branch
Fagging and spring sliding pin component are formed.There are three positioning holes in the chuck body bottom surface, and three support nails are installed respectively, use
Positioned in workpiece sole plane；There is a through hole in the chuck body bottom center, thereon equipped with vacuum suction component, for work
Part sole plane is tensed；Supporting plate is respectively provided with two adjacent sides of chuck body, the positioning for workpiece side basal plane；
Spring sliding pin component is housed in the chuck body of workpiece both sides basal plane opposite side, the spring sliding pin component determined with two straight pins
Position, and the chuck body is fixed in two screws, for being compressed to workpiece side basal plane, wherein workpiece long side fills
There are two spring sliding pin components, workpiece short brink is equipped with a spring sliding pin component.The spring sliding pin component is by body, spiral shell
Nail, spring, adjusting screw, lead, end cap and sliding pin composition；Bullet is sequentially loaded into the spring sliding pin component body counterbore
Spring, sliding pin, spring, then make in the traveller insertion sliding pin hole of lead front end, be finally fixed to end cap with four uniform screws
On its body, and adjusting screw is screwed into end cap central screwed hole until sliding pin just stretches out 0-1mm from its body.
The Digit Control Machine Tool spring sliding pin compressing fixture that is used for is in use, first have to workpiece being placed into three support nails
On；Next allows workpiece both sides basal plane to distinguish torsional spring sliding pin components side with inner hexagon spanner respectively against on lateral bolster fagging
Face adjusting screw, the sliding pin of spring sliding pin component is set to touch workpiece successively；Then vacuum suction components side compressed air valve is opened
Door, vacuum cup tense workpiece sole plane；Due to the angle change proportional to clamping force size that screw rotates, root is now answered
According to clamping force size needed for workpiece, continue adjusting screw on torsional spring sliding pin component with inner hexagon spanner, make workpiece along two water
Square fixed to reliable grip, so as to reach the purpose of Quick holding part, avoid clamping force excessive and cause workpiece deformation and
The generation of position error.
The beneficial effects of the utility model are, simple to operate, and clamping force size is controllable, can not only fast positioning clamping
Fixed workpiece, and workpiece deformation and position error in clamping process can be reduced, so as to improve the machining accuracy of part and processing
Efficiency.
