Positioning and clamping device for fixing small-size workpiece

Abstract

A positioning and clamping device for fixing small workpieces is provided, which includes a bottom plate, a workpiece positioning platform for carrying workpieces and a toggle clamp device for pressing the workpiece are fixedly connected to the upper surface of the base plate, and one end of the pressing arm in the toggle clamp device is fixed. The anti-rotation connecting plate is connected, and the elastic pressing piece for directly compressing the workpiece is arranged on the anti-rotation connecting plate. The present invention combines an elbow clamp device and an elastic pressing part to make a special positioning table, which can realize the positioning and clamping of small workpieces, and has reliable and stable positioning, simple structure and convenient manufacture. In the present invention, an elastic pressing part for directly pressing the workpiece is provided on the anti-rotation connecting plate. The elastic pressing part directly in contact with the workpiece adopts a spring plunger, and the spring plunger will not directly apply a pressing force to the workpiece, and will There is a certain buffering effect on the workpiece, thus effectively preventing damage to small workpieces.

Description

technical field [0001] The invention belongs to the technical field of fixture devices, and in particular relates to a positioning and clamping device for fixing small workpieces. Background technique [0002] For some parts with relatively small volume such as circuit boards, in the process of welding and processing, because the volume is too small, it is very inconvenient to position and fix them, and the work efficiency is low. Moreover, for these small parts, because they are too small and can bear little force, they are prone to damage during the positioning process. Therefore it is necessary to propose improvements. Contents of the invention [0003] The technical problem solved by the present invention is to provide a positioning and clamping device for fixing small workpieces. The present invention can realize the positioning and clamping of small workpieces through the toggle clamp device and elastic pressing parts combined with the workpiece positioning platform...

Problems solved by technology

[0002] For some parts with relatively small volume such as circuit boards, in the process of welding and processing, due to the small size, it is inconvenient to fix them and the work efficiency is low.

Moreover, for these small parts, because they are too small and can withstand small forces, they are prone to damage during the positioning process.
