Feeding and discharging device for machining steel plates

Abstract

The invention relates to the technical field of machining, and particularly discloses a feeding and discharging device for machining steel plates. The feeding and discharging device comprises a frameassembly, a supporting and fixing assembly, a top telescopic sliding assembly and a fixing and clamping assembly, wherein the supporting and fixing assembly is composed of a first lifting cylinder anda supporting plate, and the top telescopic sliding assembly is composed of a sliding top plate, a rack fixing plate and a driving motor. According to the feeding and discharging device, a workpiece is clamped and fixed through the fixing and clamping assembly, and the horizontal transfer of the workpiece is completed through the top telescopic sliding assembly, so that the safety of the whole feeding and discharging process is improved, and the accuracy of the workpiece transmission direction is improved; and in the workpiece feeding and discharging process, the workpiece is lifted through the expansion of a second lifting cylinder, the workpiece clamping tightness is controlled through a second telescopic cylinder, the workpiece is loosened through a third telescopic cylinder, the wholeprocess is short in time, and unstable factors in manual feeding and discharging are eliminated, so that the safety and efficiency of feeding and discharging are further improved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a loading and unloading device for steel plate processing. Background technique [0002] In mechanical processing, steel plate processing is a common form of processing. Before processing, it is generally necessary to move the steel plate to the processing table of the machine tool, and to position and fasten the workpiece before processing. In the prior art, the steel plate is loaded The process of loading and unloading is generally completed by a crane. The operation is simple and can meet the requirements for loading and unloading of general steel plate parts. However, it still has the following disadvantages in the actual use process: [0003] .The whole hoisting process needs to fix the four corners of the workpiece. During the hoisting process of the crane, the steel plate is in a relatively free state in multiple directions, so there are unstable factors, and it is easy ...

AI Technical Summary

Problems solved by technology

[0003] .The whole hoisting process needs to fix the four corners of the workpiece. During the hoisting process of the crane, the steel plate is in a relatively free state in multiple directions, so there are unstable factors, and it is easy to deflect during the hoisting process, which will affect the stability of the hoisting sex;

[0004] .In the prior art, when hoisting, after hoisting to the working plane, the steel plate needs to be stabilized first, and then slowly lowered to the working table. The whole process takes a long time and affects the processing progress
