Thick-plate eccentric cam-type automatic clamp for automated equipment

Abstract

This invention provides an innovative thick-plate type eccentric cam-type automatic clamping device for automated equipment, comprising: a main clamping body, the main body of which is a long flat plate, forming a circular protrusion, a pair of first lugs and a pair of second lugs; a pressure plate having a first end and a second end, the first end forming a first pivot extension, and the two ends forming a second pivot extension, the second pivot extension being pivotally connected to the pair of first lugs, and another circular protrusion forming on the side; a spring, one end of which is mounted on the circular protrusion, and the other end abutting against the circular protrusion of the pressure plate; a rotary connector pivotally connected to the first pivot extension; and a clamping member having a clamping end, which is pivotally connected to the rotary connector and the pair of second lugs respectively, the clamping end being rotatable relative to the long flat plate, thereby clamping or releasing a plate-shaped workpiece with the long flat plate.

Claims

1. A thick-plate type eccentric cam automatic clamp for automated equipment, comprising: a main clamping body, the main body being a long flat plate, a circular protrusion formed in the center of the long flat plate, a pair of first lugs beside the circular protrusion, a first pivot hole respectively formed at the corresponding position of the pair of first lugs, a pair of second lugs at one end of the long flat plate adjacent to the pair of first lugs, a second pivot hole respectively formed at the corresponding position of the pair of second lugs; a pressure plate having a first end and a second end, the first end forming a first pivot extension having a third pivot hole, a second pivot extension forming between the two ends, a fourth pivot hole formed on the second pivot extension, the fourth pivot hole being pivotally connected to the first pivot holes through a pivot member, and another circular protrusion formed on the side; a spring, one end mounted on the circular protrusion, the other end abutting against the circular protrusion of the pressure plate; A rotary connector having a pair of fifth pivot holes and a pair of sixth pivot holes, the pair of fifth pivot holes being pivotally connected to the third pivot hole via a pivot member; and a clamping member having a clamping end and a seventh pivot hole and a pair of eighth pivot holes, the seventh pivot hole being pivotally connected to the pair of sixth pivot holes via a pivot member, the pair of eighth pivot holes being pivotally connected to the second pivot holes via a pivot member, the clamping end rotating relative to the long flat plate to clamp or release a plate-shaped workpiece with the long flat plate.

2. The thick-plate type eccentric cam automatic clamping device for automated equipment as described in claim 1, further comprising a bundle plate having two first screw holes, and a long flat plate having a second screw hole corresponding to the first screw holes. The long flat plate on both sides of the second screw holes forms a snap-fit ​​portion outwards. The bundle plate is fixedly connected to the snap-fit ​​portions of the long flat plate by screws locking the first screw holes and the corresponding second screw holes.

3. The thick-plate type eccentric cam automatic clamping device for automated equipment as described in claim 2, wherein the clamping plate rotates relative to the main clamping body at the first pivot extension and is restricted to rotation in one direction by the clamping plate.

4. The thick-plate type eccentric cam automatic clamping device for automated equipment as described in claim 3, wherein the pressure plate rotates when the second end is pressed down, thereby compressing the spring; when the downward pressure is released, the pressure plate is rebounded by the spring and rotates in the opposite direction.

5. The thick plate type eccentric cam automatic clamping device for automated equipment as described in claim 1, wherein a groove is formed below each of the pair of second lugs for temporarily accommodating the plate-shaped workpiece.

6. The thick-plate type eccentric cam automatic clamping device for automated equipment as described in claim 1, wherein when the pressure plate rotates causing the second end to move away from the long flat plate, the first pivot extension rotates the rotating connector, the rotating connector rotates the clamping member, thereby causing the clamping end to rotate and move toward the long flat plate to reduce the gap between them.

7. The thick-plate type eccentric cam automatic clamping device for automated equipment as described in claim 1, wherein when the pressure plate rotates causing the second end to approach the long flat plate, the first pivot extension rotates the rotating connector, the rotating connector rotates the clamping member, thereby causing the clamping end to rotate away from the long flat plate to increase the gap between them.
