The specific implementation mode of the present invention is further described below in conjunction with the accompanying drawings.
A kind of automatic feed drilling machine of quick-replaceable drill bit as shown in Fig. 1,2,3,4,5, including lathe bed 1, motor 2,
Hoistable platform 3, power transfer 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 mounted on the hoistable platform 3, and the power transfer mechanism is the motor
Movement and power pass to the automatic feed mechanism 9.
A kind of automatic feed drilling machine of quick-replaceable drill bit as shown in Fig. 1,2,3,4,5, 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
Suitable position, retaining element is on lathe bed 1 when the position of drill bit 10 is overlapped with unprocessed hole location for adjustment part position, 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 rotary motion of drill bit 10, at the same time some power screw rod is passed to by motor pulley II 5 and belt II 6
901, since the diameter of motor pulley I 4 is more than the diameter of motor pulley II 5, and the diameter and splined shaft of screw belt wheel 7
Belt pulley 8 it is equal, can thus make to generate relative motion between screw rod 901 and splined shaft 902, drill bit 10 rotation while
Auto-feed moves downward, and when drill bit 10, which feeds certain stroke, completes boring action, spring II 906 is compressed, screw rod 901
Screw thread and drill holder 904 screw thread disengaging screw, just feed-disabling only does rotary motion to drill bit 10, then changes motor
2 steering, under the action of spring II 906, the screw thread of screw rod 901 screws again with the screw thread of drill holder 904, and drill bit 10 is certainly
It is dynamic to retract, screwed when the screw thread of screw rod 901 is detached from the screw thread of drill holder 904, drill bit 10 just stops retracting, spring I 905 by
To compression, drill bit 10 equally only does rotary motion, and a hole machined is completed at this time.If the aperture of next part and first
The aperture of part is identical, drills without needing to change drill bit and directly adjusting part position.If the aperture of next part and the
The aperture of one part differs, then needs to change drill bit.When more bit change, former drill bit 10 is rotated by a certain angle counterclockwise downwards
It extracts, adjusts the mounting plane 1001 of the green bit 10 needed replacing until parallel with the axis of positioning pin 9041, be inserted at this time
Green bit 10, and when being rotated clockwise to fixed pan 1002 and being close to the side of positioning pin 9041, drill bit 10 installs
Finish, repeats above-mentioned set-up procedure and continue to drill.After a certain edge wear of blade, blade rotation 180 degree is replaced into another knife
Sword can work on, must more allowing blade replacement after blade is completely worn out.
