Multi-layer type automatic clamp capable of conveniently and rapidly clamping flat boards

Abstract

The invention discloses a multi-layer type clamp capable of conveniently and rapidly clamping flat boards. The multi-layer type clamp comprises a multi-layer type framework, positioning boards and compressing mechanisms; the multi-layer type framework is provided with the multiple positioning boards up and down; the compressing mechanisms for compressing the flat boards are arranged above the positioning boards; each compressing mechanism is connected with the same hydraulic oil circulating mechanism; guide blocks are arranged on two sides of each positioning board; and a check block is arranged at one end of the framework. Automatic compressing is achieved through a hydraulic device, so that the clamping time of staff is shortened, and dismounting is convenient.

Description

technical field [0001] The invention relates to the field of sewing machine parts processing equipment, in particular to a multi-layer automatic clamp that is convenient for fast clamping. Background technique [0002] When the current sewing machine plate is processed, it is mainly clamped by the positioning fixture. When the sewing machine plate is clamped, it is necessary to go around to find the positioning pin on the base plate, and then position the positioning pin hole of the plate against the base plate. Pin, insert the positioning pin into the positioning pin hole of the plate, so as to realize the positioning of the plate, but the current multi-layer plate fixture, because the top surface is blocked, when people are positioning, the line of sight is blocked, and the plate positioning It is not easy to locate; [0003] After the positioning is completed, it needs to be pressed by a pressing mechanism. The current pressing mechanism mainly uses bolts to press the pr...

[0002] When the current sewing machine plate is processed, it is mainly clamped by the positioning fixture. When the sewing machine plate is clamped, it is necessary to go around to find the positioning pin on the base plate, and then position the positioning pin hole of the plate against the base plate. Pin, insert the positioning pin into the positioning pin hole of the plate, so as to realize the positioning of the plate, but the current multi-layer plate fixture, because the top surface is blocked, when people are positioning, the line of sight is blocked, and the plate positioning It is not easy to locate;

[0003] After the positioning is completed, it needs to be pressed by a pressing mechanism. The current pressing mechanism mainly uses bolts to press the pressing block. The method of pressing the pressing block through the bolt needs to be manually screwed to make the pressing block press the workpiece. Tight, because the clamping is performed by manually twisting the bolts, the efficiency of clamping is relatively slow. During the processing, due to the vibration of the workpiece, the bolts are loose during the vibration, resulting in the workpiece not being compressed during the processing and jumping, which affects Workpiece machining accuracy
