Referring to fig. 1, the high-precision universal pneumatic clamp provided by this embodiment includes an installation base plate 1, where the installation base plate 1 is provided with an installation frame 2 for installing a workpiece, and a pneumatic clamping assembly for clamping the workpiece on the installation frame 2; the mounting frame 2 is provided with a mounting groove 21 for mounting a workpiece; the pneumatic clamping assembly comprises a first driving cylinder 3, a sliding plate 4 is arranged at the driving end of the first driving cylinder 3, and the sliding plate 4 is arranged on a first linear guide mechanism 5; a second driving air cylinder 6 is installed on the sliding plate 4, a driving sliding block 7 is installed at the driving end of the second driving air cylinder 6, the driving sliding block 7 is installed on a second linear guide mechanism 8, and a clamping block 9 used for clamping a workpiece in the installation groove 21 is detachably installed on the driving sliding block 7; the driving slide block 7 is provided with an installation clamping groove 71 for installing the clamping block 9, the clamping block 9 is provided with an inserting part 91 inserted into the installation clamping groove 71, a plurality of positioning holes 72 are symmetrically and uniformly distributed on the inner side surface of the installation clamping groove 71, and the inserting part 91 is provided with elastic positioning parts 92 which are respectively clamped with the positioning holes 72 in a one-to-one corresponding manner.
It should be noted that, the clamp structure of the existing workpiece is improved in the embodiment, the clamping structure driven by the air cylinder is adopted, the clamping force is stable, the positioning accuracy and the mounting stability of the workpiece are ensured, the structural design is simple, the assembly is convenient, the clamping block 9 is mounted through the detachable mounting structure of the elastic positioning piece 92 and the positioning hole 72, different clamping blocks 9 can be replaced according to different shapes of the actual workpiece, the universal type is stronger, and the operation is simpler and more convenient.
Specifically, when the workpiece is positioned and clamped, the workpiece is installed in an installation groove 21 of the installation frame 2, an opening is formed in one side, corresponding to the clamping block 9, of the installation groove 21, the workpiece protrudes out of the opening, the workpiece is clamped by moving the clamping block 9 to one side of the installation frame 2, and the installation stability of the workpiece can be guaranteed. Before the pneumatic clamping assembly carries out clamping operation, the first drive end that drives actuating cylinder 3 is in the state of withdrawing, the second drives the drive end that drives actuating cylinder 6 and is in the state of stretching out, it is when carrying out clamping operation, the first drive end that drives actuating cylinder 3 stretches out, drive slide 4 and release along 5 directions of first straight line guiding mechanism, the second that installs on slide 4 drives actuating cylinder 6 and removes to the work piece direction along with slide 4, at this moment, press from both sides tight piece 9 and mounting bracket 2 and correspond, the work piece is located between pressing from both sides tight piece 9 and mounting bracket 2, the second drives actuating cylinder 6 pneumatics, its drive end withdraws, it slides to drive slider 7 along second straight line guiding mechanism 8, thereby it removes to drive to press from both sides tight piece 9 to mounting bracket 2 direction, press from both sides tight work piece, realize pressing from both sides tight to the work piece. Through the cylinder drive, power take off is rapider, and efficiency is higher, and the clamp force is more stable.
Referring to fig. 2, it should be noted that the clamping block 9 matched with the shape of the workpiece can be selected to clamp the workpiece according to the shape of the workpiece in actual production. When the inserting part 91 of the clamping block 9 is installed with the installation clamping groove 71 of the driving slider 7, it should be noted that the size of the inserting part 91 is matched with that of the installation clamping groove 71, and the elastic positioning piece 92 has an elastically telescopic end part protruding out of the surface of the inserting part 91, so that in the process of inserting the inserting part 91 into the installation clamping groove 71, the elastic positioning piece 92 is extruded by the inner side surface of the installation clamping groove 71 and the ports of the positioning holes 72 and is compressed to be flush with the surface of the inserting part 91, thereby facilitating the insertion of the inserting part 91 into the installation clamping groove 71; after the inserting part 91 is installed in place, the elastic positioning element 92 corresponds to the positioning hole 72, and at this time, the elastic positioning element 92 loses external extrusion force, extends into the positioning hole 72 under the action of self elastic restoring force, and is clamped with the positioning hole 72 one by one, so that the installation stability of the clamping block 9 is ensured.
