Embodiment Construction

[0008] Such as figure 1 , 2 As shown: 1 is a rotary cylinder, the output end 12 of the rotary cylinder 1 is connected with the upper clamping arm 2 through the connecting piece 3, and when the output end rotates, the upper clamping arm 2 can be driven to rotate. The lower clamp arm 4 is matched with the upper clamp arm 2 . The lower clamp arm 4 is rotatably connected to the support arm 9 by the rotating shaft 8, the support arm 9 is fixedly connected with the support base 11 by bolts, and the support base 11 is relatively fixed with the cylinder body of the cylinder 1. A connecting rod 7 is connected between the rear ends of the upper clamping arm 2 and the lower clamping arm 4, and the two ends of the connecting rod 7 are connected to the lower clamping arm 4 and the upper clamping arm 2 through the first bearing pin 14 and the second bearing pin 10 respectively. active connection. The front inner workpiece clamping surfaces of the upper clamp arm 2 and the lower clamp arm...

Abstract

The invention discloses a double-clamping mechanism. The double-clamping mechanism comprises a rotary cylinder, the output end of the rotary cylinder is connected with an upper clamping arm, a lower clamping arm is matched with the upper clamping arm and rotationally connected with a support arm through a rotating shaft, the support arm is firmly connected with a support seat, the support seat is relatively fixed with a cylinder body, a connecting bar is connected between the rear ends of the upper clamping arm and the lower clamping arm, two ends of the connecting bar are respectively connected with the upper clamping arm and the lower clamping arm in a movable mode through pin shafts, and the workpiece clamping surface of the inner side of the front of the upper clamping arm is parallel to the workpiece clamping surface of the inner side of the front of the lower clamping arm. According to the double-clamping mechanism, when the cylinder works, the upper clamping arm can rotate along with the cylinder and drive the lower clamping arm to rotate through the connecting bar, the upper clamping arm and the lower clamping arm rotate in the opposite directions to clamp or loosen a workpiece, and the lower part of the workpiece is supported in a swinging mode. The double-clamping mechanism is simple in structure, flexible and reliable in action and low in manufacturing cost.

Description

technical field [0001] The invention relates to a mechanism for bidirectionally clamping workpieces. Background technique [0002] At present, the fixture for clamping the workpiece requires swing support in some special places, which is supported by a swing cylinder and needs to be stopped. This method has a complicated structure and high manufacturing cost. Contents of the invention [0003] The object of the present invention is to provide a double clamping mechanism with simple structure, reliable action, realizing swing support through linkage and reducing manufacturing cost, so as to overcome the shortcomings of the prior art. [0004] The double clamping mechanism of the present invention includes a rotary cylinder, the output end of the rotary cylinder is connected with an upper clamping arm, and the upper clamping arm is equipped with a lower clamping arm, and the lower clamping arm is connected to the support arm through a rotating shaft, and the support arm and ...
