Specific embodiment
Specific embodiment of the invention is further described below in conjunction with the accompanying drawings.
A kind of automatic feed drilling machine of the quick-replaceable drill bit as shown in Fig. 1,2,3,4,5, including lathe bed 1, motor 2,
Hoistable platform 3, Poewr transmission mechanism 4,5,6,7,8,11, automatic feed mechanism 9, drill bit 10, height adjustment mechanism 12；The electricity
Motivation 2 and the automatic feed mechanism 9 are arranged on the hoistable platform 3, and the Poewr transmission mechanism is the motor
Motion and power pass to the automatic feed mechanism 9.
A kind of automatic feed drilling machine of the quick-replaceable drill bit as shown in Fig. 1,2,3,4,5, its application method and specific step
It is rapid as follows：The part that will be processed is placed on lathe bed 1, and then adjusting height adjustment mechanism 12 makes drill bit 10 be in above part
Correct position, adjustment part position when the position of drill bit 10 overlaps with unprocessed hole location retaining element on lathe bed 1, then
Start motor 2, motor 2 is transmitted power by motor pulley I 4, motor pulley II 5 and belt I 11, belt II 6
To automatic feed mechanism 9, specially a part of power passes to splined shaft 902 by motor pulley I 4 and belt I 11, realizes
The gyration of drill bit 10, at the same time some power passes through motor pulley II 5 and belt II 6 passes to screw rod
901, due to the diameter with diameter greater than motor pulley II 5 of motor pulley I 4, and the diameter and splined shaft of screw belt wheel 7
Belt pulley 8 it is equal, can thus make to produce relative motion between screw rod 901 and splined shaft 902, drill bit 10 rotate while
Auto-feed is moved downward, and when drill bit 10 feeds certain stroke completes boring action, spring II 906 is compressed, screw rod 901
The screw thread of screw thread and drill holder 904 depart from and screw, just feed-disabling only does gyration to drill bit 10, then changes motor
2 steering, in the presence of spring II 906, screw thread and the screw thread of drill holder 904 of screw rod 901 are screwed again, and drill bit 10 is certainly
It is dynamic to return, screwed when the screw thread of screw rod 901 departs from the screw thread of drill holder 904, drill bit 10 just stops returning, and spring I 905 is received
To compression, drill bit 10 equally only does gyration, and now a hole machined is completed.If the aperture of next part and first
The aperture of part is identical, and directly adjusting part position without more bit change is drilled.If the aperture of next part and the
The aperture of one part differs, then need more bit change.It is during more bit change, the rotate counterclockwise certain angle of former drill bit 10 is downward
Extract, adjustment needs the mounting plane 1001 of the green bit 10 changed up to the diameter parallel with alignment pin 9041, now inserts
Green bit 10, and when being rotated clockwise to fixed pan 1002 and being close to the side of alignment pin 9041, drill bit 10 is installed
Finish, repeat above-mentioned set-up procedure and continue to drill.After a certain edge wear of blade, blade rotation 180 degree is changed into another knife
Sword can work on, must more allowing blade replacement after blade is completely worn out.
