Description

一种径向沟槽加工刀具A radial groove machining tool

技术领域technical field

本实用新型涉及一种径向沟槽加工刀具,适用于在工件表面加工径向沟槽,属于机械加工刀具技术领域。The utility model relates to a radial groove processing cutter, which is suitable for processing radial grooves on the surface of a workpiece, and belongs to the technical field of mechanical processing cutters.

背景技术Background technique

径向沟槽是机械加工中十分常见的一种工件廓形,尤其是在槽的两侧设有角度或者槽的侧面设有圆角,如果采用传统的标准刀具,需要平头型立铣刀、球头型立铣刀两种刀具组合加工才能实现,单独使用平头型立铣刀无法加工出槽的两侧设有角度;单独使用球头型立铣刀无法加工出槽的底面与槽的侧面夹角处的尖点;所以必须要先用球头型立铣刀加工出槽的两侧和圆角,再用平头型立铣刀加工出槽的底面。Radial grooves are a very common workpiece profile in machining, especially if there are angles on both sides of the groove or rounded corners on the sides of the groove. If traditional standard tools are used, flat end mills, Ball-end milling cutters can only be processed by combining two kinds of tools. Flat-end milling cutters alone cannot process the angles on both sides of the groove; ball-end milling cutters alone cannot process the bottom surface and sides of the grooves. The sharp point at the included corner; therefore, the sides and rounded corners of the groove must be machined with a ball end mill first, and then the bottom surface of the groove must be machined with a flat end mill.

现有技术中,常规的径向沟槽加工刀具主要存在以下问题:In the prior art, conventional radial grooving tools mainly have the following problems:

第一、需要不同类型的刀具加工两次,导致径向沟槽的加工周期较长。First, different types of tools are required to be machined twice, resulting in a longer machining cycle for radial grooves.

第二、刀具接刀的位置容易产生毛刺,需要人工去除毛刺,导致径向沟槽的加工过程较为复杂。Second, the position where the tool meets the knife is prone to burrs, which need to be removed manually, which makes the machining process of the radial groove more complicated.

第三、未去除的毛刺会划伤产品表面,导致加工产品不良率较高。Third, unremoved burrs will scratch the surface of the product, resulting in a high defective rate of processed products.
