Detailed Description

Example (b):

as shown in fig. 1 and 2, the quick clamping device for shaft workpieces comprises a main clamp 1, an auxiliary clamp 2, a clamp rod 5, a connecting plate 3 and a force application rod 4. Main 1 and vice pincers 2 all include that the arc presss from both sides gets end and link, main 1 link of pincers is equipped with two first spliced eye 6, vice 2 link of pincers inserts first spliced eye 6 and rotates through the dabber and connect main pincers 1, main 1 clamp of pincers get the end and vice 2 clamp of pincers get the end and form to keeping silent in opposite directions.

The end part of the connecting end of the main pliers 1 is provided with two first inserting grooves 7, the end part of the connecting end of the main pliers 1 is connected with a force application rod 4 through a connecting plate 3, one end of the connecting plate 3 is fixedly connected with the force application rod 4, the other end of the connecting plate is inserted into the first inserting grooves 7 and is connected with the connecting end of the main pliers 1 through a mandrel rotation, a second inserting hole 8 is arranged at the center of the connecting plate, a second inserting groove 9 is arranged on the outer side of the clamping end of the auxiliary pliers 2, one end of the clamping rod 5 is inserted into the second inserting hole 8 and is connected with the connecting plate 3 through the mandrel rotation, and the other end of the clamping rod is inserted into the second inserting groove 9 and is connected with the clamping end of the auxiliary pliers 2 through the mandrel rotation. The inner sides of the clamping ends of the main pliers 1 and the auxiliary pliers 2 are both provided with friction bushings 10.

The working principle is as follows: when the force application rod 4 is pressed downwards, the clamp rod 5 applies forward thrust to the auxiliary clamp 2, and meanwhile, backward tension is applied to the main clamp 1 through the connecting plate 3, so that the jaws are automatically held tightly; when the force application rod 4 is lifted up, the clamp rod 5 applies backward pulling force to the auxiliary clamp 2, and simultaneously applies forward pushing force to the main clamp 1 through the connecting plate 3, so that the jaws are automatically separated.

The above-described embodiments are merely preferred and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.

In the description of the present invention, it is to be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the equipment or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
