Specific embodiment
Referring to Fig. 1-4, the utility model relates to a kind of square tubes, band steel class workpiece special jaw clamping device, including claw
Seat 1, fixed jaw 2, movable claw 3 and cylinder 5, the fixed jaw 2 are mounted on the bottom surface of master jaw 1 and stretch out one end of master jaw 1,
One end of the movable claw 3 is equipped with arc compressed part 3.1 and hingedly forms hinge A, the other end by rotary shaft 4 and master jaw 1
Hinge B is hingedly formed with the piston rod of cylinder 5, the cylinder body of the cylinder 5 and the otic placode 7 on master jaw 1 hingedly form hinge C,
Workpiece 6 is placed between fixed jaw 2 and arc compressed part 3.1.Entire claw clamping device is mounted on machine tool feed device, into
The feed motion of row workpiece.
1 front and rear sides of master jaw correspond to cylinder 5 equipped with backplate 1.1.Backplate 1.1 plays the role of protecting cylinder.
The arc compressed part 3.1 includes the first arc protrusion 3.1.1 and the second arc protrusion 3.1.2, first arc
It is connected between shape protrusion 3.1.1 and the second arc protrusion 3.1.2 by arc-shaped depression portion 3.1.3, first arc protrusion 3.1.1
Clamp workpiece 6.Keep the intensity of arc compressed part 3.1 higher by more designed arc-shaped appearances, movable claw 3 is hardly damaged, while making activity
Pawl 3 and the compressive deformation of 6 clamping surface of workpiece are small.
The hinge C is higher than hinge A, and the hinge B is placed in the top between hinge A and C.When movable claw 3 and cylinder 5
When angle is 90 ° between piston rod, clamping effect is best.
The corresponding hinge C of the backplate 1.1 is equipped with notch 1.1.1.The design of notch 1.1.1 is while protecting cylinder 5, just
In the dismounting of cylinder.
Working principle:
The piston rod of cylinder 5 is in retracted mode, and device is in releasing orientation at this time, and workpiece 6 is square tube, and square tube is covered
Between fixed jaw 2 and the arc compressed part 3.1 of movable claw 3, the piston rod elongation of cylinder 5 drives movable claw 3 to revolve around rotary shaft 4
Turn, the arc compressed part 3.1 of movable claw 3 moves down, pressing square inside pipe wall.
The piston rod of cylinder 5 is in retracted mode, and device is in releasing orientation at this time, and workpiece 6 is square tube, and band steel is placed in
Between fixed jaw 2 and the arc compressed part 3.1 of movable claw 3, the piston rod elongation of cylinder 5 drives movable claw 3 to revolve around rotary shaft 4
Turn, the arc compressed part 3.1 of movable claw 3 moves down, and compresses the upper surface of band steel.
In addition to the implementation, the utility model further includes having other embodiments, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection scope of the utility model claims.
