设计简介
摘要
目前，常见码坯机夹盘机构有自动夹坯机构、先进机械手机构以及半自动半手动夹坯机构等多种形式。一般多采用半自动半手动机构设计，当坯条由切坯机切出并有传送带运送至夹盘正下方，夹盘在手动按钮的控制下，开始下降，到达一定高度后停止下降，并在电机传动和气缸传动控制下，横向气缸装置向中心推动，带动夹板加紧，同时纵向气缸装置向竖直方向推动，由焊接在下方的方管推动两侧的角铁从而同时将夹板加紧，达到夹坯的效果，然后由升降机构将夹盘提起并移送至烘烧轨道，依次循环。整个夹盘机构由夹板，纵横气缸装置，中心旋转轴架装置，夹板挂架装置，电动气动装置以及其他焊件装置构成。夹板两侧为直线导轨引导的侧板方管，承受压力大，并且直线性能好，摩擦力小，平稳性能好，有利于夹坯。纵向气缸装置也为加紧机构增加横向作用力，更大程度上有利于砖坯的夹紧。本文就是通过各方面考虑，综合对比传统的夹坯机构，获取整机各零件的参数，并且通过计算，论证了该设计方案的可行性。

Abstract
At present, a common code base machine chuck mechanism has automatic blank clamping mechanism, advanced mechanical hand mechanism and a semi-automatic manual blank clamping mechanism and so on many kinds of forms. The general use of semi automatic and manual mechanism design, when the strip by cutting machine cut out and the conveyor to the chuck is below, chuck in the manual button control, began to decline, reaches a certain height to halt the decline, and in motor drive and a cylinder driving control, horizontal cylinder device to the center push, drive the splint intensified, while a longitudinal cylinder device to a vertical drive, at the bottom of the tube driven by welding on both sides of the angle iron and at the same time to reach the splint, blank clamping effect, and then by the lifting mechanism to chuck up and transferred to bake track, followed by cycle. The clamp mechanism consists of a splint, vertical and horizontal cylinder device, a center rotating shaft frame device, clamping plate rack device, electric pneumatic device and other welding device. Two sides of the splint is a linear guide rail guide plates of the square tube, large bearing pressure, and the straight line performance, small friction force, stable performance, is conducive to the blank clamping. Longitudinal cylinder device for clamping mechanism to increase the transverse force, more conducive to the clamping tile. This paper is through the aspects to consider, comprehensive comparison of traditional blank clamping mechanism, acquiring the various parameters of parts, and through calculation, it proves the feasibility of design scheme.
