技术领域technical field
本发明属于金属切削加工刀具技术领域，具体涉及一种圆柱定位的螺纹柄钻头。The invention belongs to the technical field of metal cutting tools, and in particular relates to a threaded shank drill bit with cylindrical positioning.
背景技术Background technique
目前钻头是行业内通用的钻孔工具，钻头主要由刀柄和刀头组成，其中刀柄最常见的形制为圆柄和方柄，这两种形制的刀柄均是通过钻头夹具与刀柄外表面之间的摩擦力来夹持钻具，这种夹持方式的打孔精度不高。At present, the drill bit is a common drilling tool in the industry. The drill bit is mainly composed of a handle and a cutter head. The most common shapes of the handle are round handle and square handle. The friction between the outer surfaces is used to clamp the drilling tool, and the drilling accuracy of this clamping method is not high.
行业内有一种钻头的刀柄外圆面上设置有紧固螺纹，紧固螺纹与钻头夹具之间通过螺纹副进行连接连接，钻柄与钻头夹具的连接面积更大，所以两者间的旷动大大减少，提高了孔的加工精度。但是螺纹的加工过程中，螺纹的精度容易发生较大的变化，且螺纹的连接过程中，发生接触、干涉的点或面很多，因此，这种钻头的打孔精度受到螺纹精度和螺纹副的影响很大。In the industry, there is a kind of fastening thread on the outer surface of the shank of the drill bit. The fastening thread and the drill fixture are connected through a thread pair. The connection area between the drill shank and the drill fixture is larger, so the gap between the two The movement is greatly reduced and the machining accuracy of the hole is improved. However, in the process of thread processing, the accuracy of the thread is prone to large changes, and in the process of thread connection, there are many points or surfaces where contact and interference occur. Therefore, the drilling accuracy of this drill is affected by the thread accuracy and the thread pair. great influence.
发明内容Contents of the invention
本发明的目的在于克服现有技术的不足而提供的一种圆柱定位的螺纹柄钻头。The object of the present invention is to provide a cylindrically positioned threaded shank drill bit for overcoming the deficiencies of the prior art.
本发明是这样实现的：一种圆柱定位的螺纹柄钻头，包括刀柄和刀头，所述的刀柄和刀头同轴设置，其特征在于：所述的刀柄外圆面上为紧固螺纹，刀柄和刀头的连接部设置有圆柱状的定位圆柱，所述定位圆柱的直径不小于紧固螺纹的大径。The present invention is achieved in the following way: a cylindrically positioned threaded shank drill bit, including a tool handle and a cutter head, the said tool handle and the cutter head are coaxially arranged, and it is characterized in that: the outer circular surface of the said tool handle is tight For the fastening thread, a cylindrical positioning cylinder is arranged at the connecting part of the tool handle and the cutter head, and the diameter of the positioning cylinder is not smaller than the major diameter of the fastening thread.
进一步优化，所述的定位圆柱的外圆面上设置有耐磨层。Further optimization, a wear-resistant layer is provided on the outer circular surface of the positioning cylinder.
进一步优化，所述的所述耐磨层的材料为硬铬层或者渗碳层中的一种。Further optimization, the material of the wear-resistant layer is one of hard chrome layer or carburized layer.
与现有技术相比，本发明的有益效果是：由于螺纹在加工过程中，螺纹的加工精度收到螺纹加工方法的限制，螺纹加工精度不高，所以仅凭紧固螺纹拧紧，钻头的直线度不好。本装置上添加定位圆柱，钻头与钻头夹具之间通过螺纹副连接紧固，钻头夹具的顶端设置为孔洞，孔洞的内表面与钻头上定位圆柱的外圆面相接触，两者之间面与面相接触，圆柱面的加工精度在工艺上来说比螺纹的加工精度更高，更容易得到保证，通过定位圆柱的定位，本钻头的直线度更好，打孔的精度更高，大幅的提高了钻头的夹持精度和钻孔加工精度。Compared with the prior art, the beneficial effect of the present invention is: because the machining accuracy of the thread is limited by the thread machining method during the machining process, the machining accuracy of the thread is not high, so the straight line of the drill bit can be improved only by fastening the thread. The degree is not good. A positioning cylinder is added to this device, and the drill bit and the drill bit fixture are connected and fastened by a threaded pair. The top of the drill bit fixture is set as a hole, and the inner surface of the hole is in contact with the outer circular surface of the positioning cylinder on the drill bit. Contact, the machining accuracy of the cylindrical surface is higher than the machining accuracy of the thread in terms of technology, and it is easier to be guaranteed. Through the positioning of the positioning cylinder, the straightness of the drill is better, and the drilling accuracy is higher, which greatly improves the drilling accuracy. Clamping accuracy and drilling accuracy.
