The utility model discloses an anti grinding wheel offset device, which aims to provide a grinding wheel cutting machine which does not offset or reduce the offset during the cutting process. The main point of the technical scheme is that a pulley is installed before and after the lower position of the central horizontal line of the grinding wheel, and the inner side of the ring groove of the pulley is tightly attached to the grinding wheel. The center axis of the front and back two pulley is connected with the slide bar in a right angle. The back end of the sliding rod is located in the left and right sides of the slipway, and the rear end of the front sliding rod is hung with the spring, and the rear end of the back slide is attached to the spring. The principle of anti deviation is that the grinding wheel in rotation is used to drive the first two pulleys to rotate in situ, and when the grinding wheel is worn, the diameter of the wheel changes hours, and the pull spring and the rear pulley are pushed by the pull spring and the spring. Because the front and rear two pulley blocks the left and right offset of the grinding wheel piece, the cutting section is neat or nearly flat.
【技术实现步骤摘要】
一种防砂轮片偏移装置
本技术涉及用于机械制造和修理厂家常用的一种即必不可少的切割设备,更确切更具体地说是涉及用于分割长条形钢材的通称为砂轮切割机。
技术介绍
砂轮切割机其结构与做功原理如图1所示:电动机8在运转中带动安装在中心转轴7上的主动传动轮6,连及传动带5带动从动传动轮4旋转,从而带动从动传动轮4中心的传动轴3连及薄圆砂轮片9做同步转动,轴承筒座2两头内的各一个轴承(图中未示出)起着对传动轴3的定位,选用六角螺母10将砂轮片9固紧。压下把手1便可对被切割物实施切割,由于以支点即旋转点17为界其切割机后重前轻(电动机位为后),松开把手便可自动回位。由于用于分割圆钢或角钢及扁钢的砂轮片其強度有限,并且是以磨擦式原理对被切物断开,压力过小或切不动或速度慢,加大压力其砂轮片容易变形,因此其切割断面为斜线,必要时务必过车床才能达到平齐,既误工误时又造成浪费。
技术实现思路
本技术为克服上述不足,旨在提供一种在切割过程中其砂轮片不偏移或减少偏移的砂轮切割机,采用以下技术方案予以实现。在砂轮片中心水平线下位的前后各安装一个缘周带有环形槽沟的侧面滑轮,其环形槽沟内边(贴近砂轮片一侧为内)与砂轮片紧贴,前后滑轮中心轴与立杆或滑或与立杆和滑杆以直角形连为一体,滑杆中后端位于左右两侧滑道里可前后移位,前滑杆尾端系挂有拉簧;后滑杆尾端顶面与弹簧相贴。其做功过程和做功原理为:旋转中的砂轮片在实施切割中带动一前一后两滑轮原位转动,前一个为顺时针运转,后一个为逆时针运转,两滑轮之间的砂轮片下位是被切割件,依据被切割件的大小将两滑轮之距离加大或减小,当砂轮片因磨损而直径变小时,因拉簧和 ...
