Example 1
As shown in fig. 1-2, a spreader jaw mechanism, the mechanism comprising:
A base 1;
The driver 2 is arranged in the base 1, and the driving end of the driver 2 extends out of the base 1;
Specifically, a bearing is arranged at the joint of the driving end of the driver 2 and the outer surface of the base 1.
The center of the connecting piece 3 is fixedly connected with the driver 2;
a jaw frame 4 provided on the bottom of the base 1;
At least two clamping jaws 5 movably mounted on the clamping jaw frame 4;
Wherein the outer edge of the connecting member 3 is in contact with the inner surface of each jaw, and the driver 2 drives the jaws 5 to switch between an open state and a clamped state by driving the connecting member 3 up and down.
Further, the driver 2 is a single-acting cylinder, and the driving end of the driver 2 is fixedly connected with the center of the connecting piece 3.
Specifically, the driver 2 may be a diaphragm type single-acting cylinder, and has a simple structure, and mainly comprises a diaphragm, a piston and a cylinder body. The piston deforms and moves through the diaphragm, and a sealing ring is not needed for sealing. The diaphragm type single-acting cylinder has large acting area and large driving force, and is commonly used in tightening occasions, and the cylinder piston is reset and driven by external force.
