(1) process using combined drill bit assembly construction stepped hole disclosed in the present embodiment is as follows:
Counterbore device 4 and limit hole device 5 are assembled in fixed link 2 first, and electric drill is made to be clamped in the triangle rod structure of fixed link 2
On, form stepped ramp type counterbore hole making drill.Installation site of the limiter 5 in fixed link 2 is adjusted simultaneously, according to 2 middle section of fixed link
Graduation mark by idler wheel 53 adjust arrive required position, that is, construct before set counterbore depth.Then, using positioning drill bit 1 in plate
The hole heart for needing aperture is determined on material, starts electric drill, and the torsion generated when being rotated using electric drill drives fixed link 2 to rotate, in turn
The cutting 31 on hole making drill 3 and the cutter 41 on counterbore device 4 and bite 44 are driven to process plate.Specifically adding
During work, is first pierced in plate by positioning drill bit 1 and stablize its aperture center；Then by the cutting 31 of hole making drill 3 to plate into
Row cutting, opens the penetrating type circular hole of one with its same size in hole making drill circular section；Finally just by the cutter on counterbore device 4
41 and bite 44 counterbore cutting is carried out to plate.When counterbore reaches set depth, the idler wheel installed on limiter 5
53 will withstand plate surface, to prevent hole making drill 3 and counterbore device 4 from continuing to cut plate.Once perceiving idler wheel 53
Plate surface has been withstood, electric drill can be closed, stop operation construction and has taken out stepped ramp type counterbore hole making drill, has at this moment been completed
Whole construction to step cutting pattern hole.Circular luminaire 6 to be installed, which is put into step cutting pattern hole, and completes fixation can be realized circle
