技术领域technical field
本发明属于加工制造领域，涉及钻孔时，一种精确定位方法。The invention belongs to the field of processing and manufacturing, and relates to a precise positioning method when drilling holes.
背景技术Background technique
随着机械化程度的不断提高，机床的应用越来越广泛，不仅显著提高了工作效率，也极大的释放了劳动力。其中对于工件的钻孔工作是机械加工中使用最多的加工工序。钻头的位置会直接影响零件的加工精度，当钻头与所要加工孔的位置不完全重合时，将直接造成加工件的位置误差，从而达不到所需要的加工精度。With the continuous improvement of the degree of mechanization, the application of machine tools is becoming more and more extensive, which not only significantly improves the work efficiency, but also greatly releases the labor force. Among them, the drilling work of the workpiece is the most used processing procedure in machining. The position of the drill bit will directly affect the machining accuracy of the part. When the position of the drill bit does not completely coincide with the position of the hole to be machined, it will directly cause the position error of the workpiece, so that the required machining accuracy cannot be achieved.
目前，钻头与工件所需加工孔的位置，通常都是工人根据加工经验，通过人眼观察确定钻头是否位于加工孔位置的正上方的方法进行对刀。这种方法极不精确，具有很大的随意性，且加工出来的孔位置误差较大，难以满足工件的精度要求。At present, the position of the hole to be machined between the drill bit and the workpiece is usually checked by the worker based on the machining experience and by human eye observation to determine whether the drill bit is directly above the machined hole position. This method is extremely inaccurate and has great randomness, and the position error of the processed hole is relatively large, which is difficult to meet the accuracy requirements of the workpiece.
发明内容Contents of the invention
本发明的目的是解决现有钻孔加工中的对刀不精确的问题，设计一种钻头钻孔的精确定位装置，当工件6加工孔有确定加工点坐标值(x，y)时，通过机床转轴X、Y方向上安装的红外激光设备照射在L形刻度尺1显示的数值来确定钻头准确到达工件钻孔位置。当工件6加工孔无确定加工点坐标(x，y)时，通过X向红外激光设备2、Y向红外激光设备4的线束交点(此交点即为钻头中心点)，来定位工件加工孔的位置。其中X向、Y方向上的红外激光设备照射在L形尺上为一条线。The purpose of the present invention is to solve the problem of inaccurate tool setting in the existing drilling process, and to design a precise positioning device for drill bit drilling. The infrared laser device installed in the X and Y directions of the machine tool shaft irradiates the value displayed on the L-shaped scale 1 to determine that the drill bit accurately reaches the drilling position of the workpiece. When the processing hole of the workpiece 6 has no definite coordinates (x, y) of the processing point, the beam intersection of the X-direction infrared laser device 2 and the Y-direction infrared laser device 4 (this intersection point is the center point of the drill bit) is used to locate the processing hole of the workpiece Location.

具体实施方式detailed description
以下结合技术方案和附图详细叙述本发明的具体实施方式。The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.
如图1、3所示，一种钻头钻孔的精确定位方法，包括包括L形刻度尺1、X向红外激光设备2、Y向红外激光设备4。As shown in FIGS. 1 and 3 , a precise positioning method for drilling a drill bit includes an L-shaped scale 1 , an X-direction infrared laser device 2 , and a Y-direction infrared laser device 4 .
图1通过X向红外激光设备2、Y向红外激光设备4照射在L形刻度尺1上的数值来准确定位工件上加工孔的位置。当工件加工孔有确定加工点坐标(x，y)时，首先根据加工工件尺寸拨动X向红外激光设备2、Y向红外激光设备4，使得激光线束能够照射在L形刻度尺1上。通过移动钻孔装置的位置，使激光线束照射到L形刻度尺1所要加工孔X、Y方向对应的坐标(x，y)上，从而通过L形刻度尺1显示的数值来控制孔的所需加工位置。随着钻孔装置位置的移动，当激光线束在L形刻度尺1上显示的数值为工件上孔的加工位置坐标(x，y)时，即实现了准确定位。Figure 1 accurately locates the position of the machining hole on the workpiece by the values irradiated on the L-shaped scale 1 by the X-direction infrared laser device 2 and the Y-direction infrared laser device 4 . When the processing point coordinates (x, y) of the workpiece processing hole are determined, firstly, the X-direction infrared laser device 2 and the Y-direction infrared laser device 4 are moved according to the size of the processed workpiece, so that the laser beam can be irradiated on the L-shaped scale 1. By moving the position of the drilling device, the laser beam is irradiated on the coordinates (x, y) corresponding to the X and Y directions of the hole to be processed by the L-shaped scale 1, so that the value displayed by the L-shaped scale 1 is used to control the hole. The position to be processed. With the movement of the position of the drilling device, when the value displayed by the laser beam on the L-shaped scale 1 is the machining position coordinates (x, y) of the hole on the workpiece, accurate positioning is achieved.
如图1所示，对于工件加工孔有确定加工点坐标值(x，y)，钻头钻孔的精确定位的操作方法，包括如下步骤：As shown in Figure 1, for the workpiece machining hole, there is a method of determining the coordinates of the machining point (x, y), and the precise positioning of the drill bit, including the following steps:
第一步，操作前期准备；The first step is to prepare for the operation;
(1)装夹好所需加工的样件，已有加工孔位置的坐标值(x，y)；(1) The sample to be processed is clamped, and the coordinate value (x, y) of the processing hole position is already available;
(2)检查L形刻度尺1位置，使其能够包络工件加工孔的位置。(2) Check the position of the L-shaped scale 1 so that it can envelop the position of the workpiece machining hole.
第二步，调节红外激光设备的角度；The second step is to adjust the angle of the infrared laser device;
根据工件尺寸大小，拨动X向红外激光设备2、Y向红外激光设备4，使得激光线束能够照射在L形刻度尺1上；According to the size of the workpiece, switch the X-direction infrared laser device 2 and the Y-direction infrared laser device 4, so that the laser beam can be irradiated on the L-shaped scale 1;
第三步，通过X向红外激光设备2、Y向红外激光设备4确定工件加工孔的位置；The third step is to determine the position of the workpiece processing hole through the X-direction infrared laser device 2 and the Y-direction infrared laser device 4;
当工件上孔的加工位置坐标(x，y)确定时，通过移动钻孔装置的位置，使激光线束照射到L形刻度尺1所要加工孔X、Y方向对应的坐标值(x，y)上，从而通过L形刻度尺1显示的数值来控制孔的所需加工位置。当激光线束在L形刻度尺1上显示的数值等于工件上孔的加工位置坐标(x，y)时，即实现准确定位。When the coordinates (x, y) of the processing position of the hole on the workpiece are determined, by moving the position of the drilling device, the laser beam is irradiated to the coordinate values (x, y) corresponding to the X and Y directions of the hole to be processed on the L-shaped scale 1 , so that the desired processing position of the hole can be controlled by the value displayed on the L-shaped scale 1. When the value displayed by the laser beam on the L-shaped scale 1 is equal to the machining position coordinates (x, y) of the hole on the workpiece, accurate positioning is realized.
图3通过X向红外激光设备2、Y向红外激光设备4的线束交点，此交点即为钻头中心点，来定位工件加工孔的位置。对于工件无确定加工点坐标(x，y)时，如图3所示，拨动X向红外激光设备2、Y向的红外激光设备4，使其激光线束交于一点，此交点即为钻头中心点。通过移动钻孔装置的位置，使激光线束的交点照射到工件加工孔的位置上，即钻头中心顺利定位到工件加工孔中心位置，实现了准确定位。Fig. 3 uses the X-direction infrared laser device 2 and the Y-direction infrared laser device 4 to locate the position of the workpiece machining hole through the intersection point of the wire harness, which is the center point of the drill bit. When the coordinates (x, y) of the processing point are not determined for the workpiece, as shown in Figure 3, move the infrared laser device 2 in the X direction and the infrared laser device 4 in the Y direction so that the laser beams intersect at one point, and this intersection point is the drill bit center point. By moving the position of the drilling device, the intersection point of the laser beam is irradiated to the position of the workpiece processing hole, that is, the center of the drill bit is smoothly positioned to the center of the workpiece processing hole, and accurate positioning is realized.
如图3所示，对于已知工件加工孔的具体加工点时，钻头钻孔的精确定位的操作方法，包括如下步骤：As shown in Figure 3, for the specific processing point of the known workpiece processing hole, the operation method of the precise positioning of the drill hole includes the following steps:
第一步，操作前期准备The first step, pre-operation preparation
装夹好所需加工的样件，并标记出加工孔位置。Clamp the sample to be processed and mark the position of the processing hole.
第二步，调节红外激光设备的角度；The second step is to adjust the angle of the infrared laser device;
通过拨动X向红外激光设备2、Y向红外激光设备4的方向，使得两个方向激光线束能交汇于一点。By dialing the direction of X to the infrared laser device 2 and Y to the direction of the infrared laser device 4, the laser beams in the two directions can converge at one point.
第三步，通过X、Y向红外激光线束交汇点确定工件加工孔的位置；The third step is to determine the position of the machining hole of the workpiece through the intersection point of the infrared laser beams in the X and Y directions;
当工件上孔的加工位置确定时，通过移动钻孔装置的位置，使X、Y向激光线束的交点照射到工件上孔的加工位置，当激光线束交点与工件上孔的加工位置重合时，即实现准确定位。When the processing position of the hole on the workpiece is determined, by moving the position of the drilling device, the intersection point of the laser beam in the X and Y directions is irradiated to the processing position of the hole on the workpiece. When the intersection point of the laser beam coincides with the processing position of the hole on the workpiece, That is to achieve accurate positioning.
当工件形状或加工孔位置改变时，通过改变红外激光设备的角度，均可实现对加工孔的位置的快速准确定位。When the shape of the workpiece or the position of the processing hole changes, the position of the processing hole can be quickly and accurately positioned by changing the angle of the infrared laser device.
