The invention relates to a bar clamping mechanism, which includes a clamping part, a housing and a driving part, and is characterized in that: the clamping part includes a transmission gear connected with the driving part, and upper clamps respectively linked with the transmission gear Holding arm, lower clamping arm, left clamping arm, right clamping arm, and four clamping hands respectively installed on the above four clamping arms; Four directions constitute a clamping cavity, and the upper clamping arm, the lower clamping arm, the left clamping arm and the right clamping arm can drive the four clamping hands to approach and move away from the clamping arm as the transmission gear rotates. Movement to maintain the center position of the cavity. The rotation of the motor drives the rotation of the transmission gear, and then drives the movement of the four clamping arms up, down, left, and right, and then drives the four clamping hands to perform the clamping action to achieve the purpose of clamping. This bar clamping mechanism has a simple structure , easy to control, reliable clamping and can clamp rods of different diameters.

The invention relates to the technical field of clamping equipment, and discloses an intelligent mechanical clamping device which comprises a driving part and a first adjusting mechanism used for driving the driving part to move transversely, and a second adjusting mechanism used for driving the driving part to move vertically is installed on an output shaft of the driving part; a clamping part is mounted on the second adjusting mechanism and comprises a mounting base and an outer sleeve fixed to the mounting base, an inner sleeve is horizontally and slidably connected into the outer sleeve, a clamping seat is horizontally and slidably connected into the inner sleeve, clamping plates are vertically and slidably connected to the two sides of the clamping seat correspondingly, and first wedge surfaces are arranged on the clamping plates; second wedge surfaces matched with the first wedge surfaces are arranged on the inner sleeve, a power piece is fixed to the mounting base, and an output shaft of the power piece is fixedly connected with the clamping seat. The clamping plates are horizontally matched with fixing pieces fixed to the inner sleeve in a sliding mode, an elastic sleeve is arranged between the clamping plates, and the elastic sleeve is fixed to the fixing pieces. The intelligent mechanical clamping device is simple in structure and is used for clamping a workpiece at a non-linear position.
