Description

一种圆周定位的机床夹具A Circumferential Positioning Machine Fixture

技术领域 technical field

本实用新型涉及一种机床夹具,特别是一种结构简单、制作方便,而且容易操作的圆周定位的机床夹具。 The utility model relates to a machine tool fixture, in particular to a machine tool fixture with simple structure, convenient manufacture and easy operation for circumferential positioning.

背景技术 Background technique

卡盘是机床上用来夹紧工件的机械装置。利用均布在卡盘体上的活动卡爪的径向移动,把工件夹紧和定位的机床附件。卡盘通常安装在车床、铣床、加工中心、外圆磨床和内圆磨床上使用,卡盘一般由卡盘体、活动卡爪和卡爪驱动机构三部分组成。当用扳手通过四方孔转动时,卡爪驱动机构带动活动卡爪同时径向位移,实现自动定心和夹紧,广泛用于夹持圆盘形的工件。 A chuck is a mechanical device used to clamp a workpiece on a machine tool. A machine tool accessory that clamps and positions workpieces by using the radial movement of movable jaws evenly distributed on the chuck body. Chucks are usually installed on lathes, milling machines, machining centers, cylindrical grinders, and internal grinders. Chucks generally consist of three parts: chuck body, movable jaws, and jaw driving mechanism. When a wrench is used to rotate through the square hole, the claw driving mechanism drives the movable claw to displace radially at the same time, realizing automatic centering and clamping, and is widely used for clamping disc-shaped workpieces.

在使用卡盘夹紧时,只是对工件作了中心定位,当所加工的圆盘形工件正反面均需要加工,且工件正反两面结构有角度位置要求,则还需要圆周方向定位,才能确保工件加工的精度,符合零件图纸要求。一般情况,加工企业利用工件正面已加工的通孔(或增加工艺通孔),作为加工工件反面的定位孔,制作该零件的专用夹具,不但费时费力而且花费不菲,如果加工件是单件或者小批量,则成本太高,难以接受。 When the chuck is used for clamping, only the center positioning of the workpiece is made. When the front and back of the processed disc-shaped workpiece need to be processed, and the structure of the front and back of the workpiece has angular position requirements, the circumferential direction positioning is also required to ensure that the workpiece The machining accuracy meets the requirements of the parts drawings. In general, processing companies use the processed through holes on the front of the workpiece (or increase the process through holes) as the positioning holes on the back of the workpiece to make special fixtures for the parts, which is not only time-consuming and expensive, but also expensive. Or small batches, the cost is too high to accept.
