Embodiment Construction

[0014] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0015] like Figure 1 to Figure 4 As shown, the present invention includes base plate 2 and briquetting block 3, base plate 2 has arc surface 24, and the arc of arc surface 24 is the same as that of workpiece 1 bottom surface 13, so it can ensure that the bottom surface 13 of workpiece 1 is compared with arc surface 24 The large contact area is conducive to the stable positioning of the workpiece 1; there are two large positioning holes 21 and two small positioning holes 22 on the arc surface 24, and the large positioning holes 21 and the small positioning holes 22 are both oblique and in the same direction. The positioning pin 5 is placed in the small positioning hole 22 to locate the workpiece 1. The two side walls of the base plate 2 have positioning grooves 23, which can fix the base plate 2 on the workbench; It is beneficial to adjust t

Abstract

The invention relates to a method for using a tool for drilling an inclined hole. The method for using the tool for drilling the inclined hole comprises the following steps that firstly, a through hole in a workpiece and a small positioning hole in the cambered surface of a base plate are aligned, and the workpiece is positioned through a positioning pin; secondly, a pressing block is pressed on a boss of the workpiece, and the pressing block is positioned and fixed through a positioning bolt and a big positioning hole; thirdly, a counter bore is machined at the position of the through hole after the workpiece is positioned, and the machined counter bore is inclined due to the facts that the radian of the bottom surface of the workpiece is the same as that of the base plate, the top surface of the boss on the workpiece is in a non-horizontal state and a drill bit is in the vertical state. The method for using the tool for drilling the inclined hole has the advantages that the structure is simple, the method is economical and practical, operation is convenient, and machining precision is high.
