Single-action three-jaw mechanical clamping mechanism

Abstract

The invention relates to a single-action three-jaw mechanical clamping mechanism. The single-action three-jaw mechanical clamping mechanism comprises a machine base, a first clamping arm, a second clamping arm, a third clamping arm, a first gear and a second gear; the first clamping arm is slidably arranged in a first linear guiding groove, the second clamping arm is slidably arranged in a secondlinear guiding groove, and the third clamping arm is slidably arranged in a third linear guiding groove; the two sides of the first clamping arm, one side of the second clamping arm and one side of the third clamping arm are each provided with a rack; and the first gear and the second gear are both rotatably installed on the machine base, the first gear meshes with the racks on the first clampingarm and the second clamping arm, and the second gear meshes with the racks on the first clamping arm and the third clamping arm. According to the single-action three-jaw mechanical clamping mechanism,no additional control device is needed, the needed mechanical actions are achieved completely through a mechanical structure, and the mechanism can be suitable for different parts by simply adjustingthe structure or / and size of clamping jaws. The mechanism is simple in structure, reliable in movement and convenient to manufacture.

Description

technical field [0001] The invention relates to a mechanical clamping mechanism, in particular to a single-acting three-jaw mechanical clamping mechanism. Background technique [0002] In automatic mechanical equipment, it is generally necessary to grasp or accurately position the produced parts. In existing equipment, mechanical claws, push rod mechanisms + positioning blocks are often used for structural design. These structures are generally aimed at specific parts and have poor production flexibility. Moreover, the structure is relatively complicated or an additional control system is required to realize the prescribed action. Contents of the invention [0003] The purpose of the present invention is to provide a single-acting three-jaw mechanical clamping mechanism. The present invention does not require additional control devices, and relies entirely on the mechanical structure to achieve the required mechanical action. By simply adjusting the structure or / and size o...
