The specific embodiment

Embodiment

See Fig. 2 and Fig. 3; A kind of bench drill; Comprise bench drill body 5, support the support platform 8 of bench drill bodies 5, three drill bits 7, be provided with the motor moving-member of motor (Fig. 2 does not show), the bench drill rotating shaft that is connected with motor, the axle sleeve 20 that entangles said bench drill rotating shaft and mobile motor in the said bench drill body 5 through support column 9.Said motor moving-member comprises the turning handle 10 of regulating the motor height, because these parts are existing governor motion commonly used, present embodiment is no longer described.

Said drill bit rotating shaft comprises drill bit link 17, and the bench drill rotating shaft is provided with the bench drill link 21 with said drill bit link coupling.When bit change 7 more, the technical staff is as long as opened drill bit link 17 and bench drill link in 21 minutes, and the drill bit link with another drill bit is connected and can accomplishes with bench drill link 21 again then.

Make drill bit link 17 and bench drill link 21 ways of connecting have three kinds usually: first kind is that drill bit link 17 is kept static, and bench drill link 21 is connected with drill bit link 17; Second kind is that bench drill link 21 is static, and drill bit link 17 is connected with bench drill link 21; The third is that drill bit link 17 and bench drill link 21 are all moved, and final the completion connects.

Present embodiment has selected the third to make drill bit link and bench drill link ways of connecting, and this sample loading mode need be set up the drill bit rotating disk 6 of mobile drill bit 7 and the travel mechanism of mobile bench drill rotating shaft.

For said travel mechanism is played a role; Said bench drill rotating shaft is for dividing body structure; Comprise the bench drill link 21 that the bench drill rotating shaft body 18 that is connected with motor and present embodiment are mentioned; Said travel mechanism comprises the handle 11 of the spring 16, back-up ring 15 and the mobile back-up ring 15 that connect bench drill rotating shaft body 18 and said bench drill link 21; The interior bore of back-up ring 15 should be less than the bore of spring 16, and back-up ring 15 just can prop up spring 16 and compress spring 16 like this, and bench drill link 21 is moved to bench drill rotating shaft body 18 directions.

And said drill bit rotating disk 6 comprises three drill headstock 22 and turntable shafts (Fig. 3 does not show) that support three different drill bits 7; Said turntable shaft is connected with said axle sleeve 20; And can drive drill headstock 22 through the rotation of turntable shaft, make the drill bit rotating shaft of the drill bit 7 that is arranged in one of them drill headstock 22 just in time relative with the bench drill rotating shaft.

Like this, more during bit change 7, promote to move the handle 11 of back-up ring 15 at needs earlier; Through spring 16 bench drill link 21 and drill bit link 17 are broken off; Then, rotary drill bit rotating disk 6 makes the drill bit rotating shaft of another drill bit just in time relative with the bench drill rotating shaft; The last handle 11 that promotes to move back-up ring 15 once more makes bench drill link 21 be connected with drill bit link 17 through spring 16.After present embodiment is set up said travel mechanism and drill bit rotating disk 6, make that more the operating efficiency of bit change 7 improves greatly, and can not occur changing wrong situation basically.

Certainly; Any structure that drill bit link 17 and bench drill link 21 are complementary can both be used to the utility model; As an example; Present embodiment has adopted such structure: said bench drill link 21 comprises main tapping 12 and is looped around main tapping 12 branch spindle nose 14 on every side that said drill bit link 17 comprises that the main groove and the confession that supply main tapping 12 to insert divide the branch groove 13 of spindle nose 14 insertions.When main tapping 12 and branch spindle nose 14 insert main groove respectively and divide groove 13, can guarantee the uniformity that bench drill rotating shaft and drill bit rotating shaft are rotated at least.

More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
