Problems solved by technology

In order to maintain synchronization, multiple wedge-shaped mechanisms are usually driven by the same drive mechanism, and the motion is transmitted to each wedge-shaped mechanism through the power transmission mechanism, resulting in a complex structure of the wedge-shaped synchronous clamping mechanism
At the same time, the wedge-shaped synchronous clamping mechanism cannot realize self-locking when the stroke is large, and the operation is inconvenient

Abstract

The invention discloses a self-centering and synchronous clamping mechanism. The self-centering and synchronous clamping mechanism comprises clamping jaws, ejecting parts, positioning parts and guiding parts, wherein a plurality of clamping jaws are uniformly arranged on the outer surface of a workpiece; the ejecting parts are arranged on the inner sides of the clamping jaws; the positioning partsare arranged on the outer sides of the clamping jaws. Through cooperation of the ejecting parts, the positioning parts and the clamping jaws, all the clamping jaws synchronously swing to achieve selfcentering and synchronous clamping of the workpieces. The self-centering and synchronous clamping mechanism is simple in structure and convenient and rapid to operate.

Description

technical field [0001] The invention relates to a synchronous clamping mechanism, in particular to a self-centering synchronous clamping mechanism. Background technique [0002] The common wedge-shaped synchronous clamping mechanism drives several wedge-shaped mechanisms to move synchronously through the driving mechanism to realize the clamping of the workpiece. In order to maintain synchronization, multiple wedge-shaped mechanisms are usually driven by the same drive mechanism, and the motion is transmitted to each wedge-shaped mechanism through a power transmission mechanism, resulting in a complex structure of the wedge-shaped synchronous clamping mechanism. At the same time, the wedge-shaped synchronous clamping mechanism cannot realize self-locking when the stroke is large, and the operation is inconvenient. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a self-centering synchronous clamping mechanism,...
