Description
技术领域 technical field
本实用新型涉及一种数控刀具结构技术领域，具体地说，涉及的是一种钻镗复合刀具。 The utility model relates to the technical field of a numerical control tool structure, in particular to a drilling and boring compound tool.
背景技术 Background technique
目前，对于数控机床，更换刀具一般都需要几秒的时间，而且加工时，刀具还需要移动的时间。加工精密度较高的通孔时，一般是要在钻完孔后，另外增加一把精镗刀具或铰刀，对钻完的孔进行精加工一遍，如果孔需要倒角，则还需要增加一把倒角刀，用于去除孔的飞边。 At present, for CNC machine tools, it generally takes a few seconds to change the tool, and the tool still needs to move during processing. When machining a through hole with high precision, it is generally necessary to add a fine boring tool or reamer after drilling the hole to finish the drilled hole. If the hole needs chamfering, it is necessary to add another A chamfering knife to deburr the hole.
因此，在正常的数控加工作业中，我们往往需要通过两把或三把刀具才能完也一个孔的加工，操作起来比较繁琐，费时费力，加工效率低下。 Therefore, in normal CNC machining operations, we often need to use two or three tools to complete the machining of a hole, which is cumbersome to operate, time-consuming and labor-intensive, and the machining efficiency is low.

具体实施方式 detailed description
下面就附图1-5对本实用新型钻镗复合刀具作以下详细说明。 Below with regard to accompanying drawing 1-5, the utility model drilling and boring compound tool is described in detail below.
在图中，我们需要加工孔径为A、厚度为D、倒角的角度为F、倒角深度为E的通孔。在刀体5的前端安装两片钻孔刀片1，其中一片是过刀体的中心的，叫中心刀片，另一片是在刀体的外侧，叫外缘刀片，根据所工件6孔的直径A的要求来确定钻孔直径B的大小，B要比A小，这样可以完成了钻孔加工的要求，如图2；接着在刀体5上安装精镗刀夹4，精镗刀夹4的安装位置C要比工件6的厚度D大，这是为了降低切削力，使得加工出来的孔更稳定，只要在精镗刀夹4上安装精镗刀片2，调节精镗刀夹4，使得精镗出的孔的大小达到直径A，如图3;再接着在刀体5上安装倒角刀片3，倒角刀片3的安装位置要大于C加D，这是为了方便刀具退刀，如图3。 In the figure, we need to process a through hole with a diameter of A, a thickness of D, a chamfering angle of F, and a chamfering depth of E. Two drilling blades 1 are installed on the front end of the cutter body 5, one of which passes through the center of the cutter body, called the center blade, and the other is on the outside of the cutter body, called the outer edge blade, according to the diameter A of the 6 holes of the workpiece According to the requirement to determine the size of the drilling diameter B, B is smaller than A, so that the requirements of the drilling process can be completed, as shown in Figure 2; The installation position C is larger than the thickness D of the workpiece 6. This is to reduce the cutting force and make the processed hole more stable. Just install the fine boring blade 2 on the fine boring tool holder 4 and adjust the fine boring tool holder 4 to make the fine boring tool holder 4 The size of the bored hole reaches the diameter A, as shown in Figure 3; then install the chamfering blade 3 on the cutter body 5, the installation position of the chamfering blade 3 should be greater than C plus D, this is for the convenience of tool retraction, as shown in the figure 3.
退刀时的步骤如下： The steps when withdrawing the tool are as follows:
1、刀体5往上抬，机床主轴定位，刀体停止旋转； 1. The cutter body 5 is lifted up, the machine tool spindle is positioned, and the cutter body stops rotating;
2、工件6朝精镗刀片2的刀尖的方向移动，然后刀体5退出工件6的孔，这样实现了只用一把刀就完成了工件6的孔加工要求。 2. The workpiece 6 moves towards the direction of the tool tip of the fine boring blade 2, and then the cutter body 5 withdraws from the hole of the workpiece 6, so that the hole processing requirement of the workpiece 6 is completed with only one knife.
