360-degree rotation pneumatic full-automatic positioning and clamping device for flat knife support

Abstract

The invention relates to a 360-degree rotation pneumatic full-automatic positioning and clamping device for a flat knife support. A plurality of compaction cylinders are uniformly distributed on the back side of a mainboard, a piston rod of each compaction cylinder is connected with an ejecting rod, the front end of each ejecting rod is connected with a horizontal push rod, the contact surface of the front end of the ejecting rod with the rear end of the push rod is an inclined plane, the front end of each push rod is connected to the lower end of a pressure plate which is vertically arranged, the central part of each pressure plate is hinged to the mainboard, a groove positioning block is arranged between the upper end of each pressure plate and the mainboard, each groove positioning block is installed on the front side of the mainboard, and the front side of each groove positioning block is provided with a projection and a positioning column used for fixing a workpiece. The 360-degree rotation pneumatic full-automatic positioning and clamping device for the flat knife support is high in automation degree and can complete a plurality of production processes with the workpiece being clamped once, after the positioning and clamping device is used, the working efficiency, the processing precision and the product quality are improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to a clamping tool in the technical field of flat knife support processing of industrial sewing machines, in particular to a 360° rotating pneumatic full-automatic positioning and clamping device for flat knife support. Background technique [0002] The shape of the flat knife support of industrial sewing machines is quite special, and it is an irregular workpiece. Because it is difficult to stably clamp and position, it is difficult to process. At present, manual clamping is usually used when processing flat knife supports. Not only is the speed slow and the clamping stability is poor, but each clamping can only perform one processing process on the workpiece, such as drilling or milling slots. During the whole production process, the clamping needs to be repeated many times, which increases the clamping error and affects the product accuracy. Contents of the invention [0003] The purpose of the present invention is to make u...

At present, manual clamping is usually used when processing flat knife supports. Not only is the speed slow and the clamping stability is poor, but each clamping can only perform one processing process on the workpiece, such as drilling or milling slots. During the entire production process, the clamping needs to be repeated many times, which increases the clamping error and affects the product accuracy.
