Working principle of the present invention is as follows:
Referring to shown in Fig. 1 to Fig. 6, during the first step extrudes drill bit, cylinder operation, when the piston of cylinder 210 is stretched
When out, drives lever cylinder connection piece 230 to move upwards, by lever cylinder connection piece 230 lever right end 222 is lifted,
Lever 220 is supported by levers support plate 240, so that lever left end 221 be made to decline, lever left end 221 is to cutter connecting rod 120
Top applies downward pressure, so that cutter connecting rod 120 declines, the decline of cutter connecting rod 120 makes double nut 123 and puts down
Washer 124 compresses disc spring 122, and spring drill chuck 140 declines with cutter connecting rod 120, and moves downward 3-4mm, at this point, three valves
Type tapered end 142 is opened, and internal diameter opens 8mm from 7mm, and drill bit 150 loses chucking power, falls into and specially put in the drill bit frame of drill bit.
In second step automatic clamping drill bit and during reply origin-location, when the present apparatus is moved to the drill bit to be clamped
Surface when, first servo motor 50 work, the first synchronous pulley 60, the second synchronous pulley 70 drive 80 work of ball-screw
Make, ball-screw 80 moves up and down on crossed roller guide rail 90 with movable slider 100, and sliding block 100 drives and moves down on drill headstock 110
Dynamic, drill chuck sleeve 130 is mobile with drill headstock 110, the adjusting of 140 upper-lower height of spring drill chuck is realized, so that it is determined that drill bit
150 by the length of 140 clamping parts of spring drill chuck；In order to which during clamping drill bit, drill bit is preferably felt relieved and is clamped,
Drill bit frame opening uses chamfer design；When ball-screw 80 declines a certain distance, drill bit 150 submerges bullet by folder portion point completely
When in the drill bit mounting hole 143 of spring drill chuck 140,210 piston retraction of cylinder, 230 pull lever right end of lever cylinder connection piece
222 declines, lever left end 221 rise, and cutter connecting rod 120 rises under the action of deforming 122 elastic force of disc spring, are returned to preload
State pulls spring drill chuck 140 to rise simultaneously, and three valve type tapered ends 142 of 140 bottom of spring drill chuck generate deformation
(tightening), pretightning force make three valve type tapered ends 142 clamp drill bit 150, the conical surface of drill chuck sleeve 130 and three valve type tapered ends
Sufficiently large pressure is generated between 142 conical surface, will not slide in boring procedure or drill bit is fallen, above two step
Realize the function that the present apparatus exchanges drill bit for automatically.
Safety when in order to improve reliability and drilling, the present invention are additionally provided with 3 close to 250,3, switch close switches
250 are mounted on sensor mounting plate 260, define the upper and lower position of sliding block sliding close to switch 250 and for detecting cunning
