Description
Technical field
The utility model relates to flexible tapping and drill clamping head field, especially be suitable for and expect that hard, tapping boring is obstructed, screw tap drill slipping when tapping boring runs into, when as main drag for causing screw tap drill bit to be pushed up fracture when moment of torsion is greater than the power that external equipment feed mechanism main shaft arranges, affect product quality.
Background technology
At present, known brill attacks dual-purpose overload protection fixture as fixture advanced on market, with Z-type and the classification of S type.See figure mono-, a kind of Z-type bores attacks combination chuck and comprises the tape splicing that to be connected with external equipment feed mechanism and bore main body 211, main shaft 216, foxyly overlap 201, adjusting nut 208.Wherein, sliding sleeve head 201 is placed in main shaft 216 by Z-type quick change collet chuck 220 side, and spring two is placed in the chamber that sliding sleeve head 201 forms with main shaft 216, main shaft 216 is equipped with for the steel ball 5 202 with Z-type quick change collet chuck 220 interlock; Axle sleeve 1, axle sleeve 2 205 is equipped with outside main shaft 216 stage casing, dish-shaped shell fragment 1 is close to by axle sleeve 2 205, dish bullet 1 contacts with reverse dish-like shell fragment 2 207, the parts internal friction sheet 209 with clutch is close to pressure sleeve 212 with outer wearing piece 210 one end, dish-shaped shell fragment 2 207 is close in one end, internal friction sheet 209 and main shaft 216 exterior surface, outer wearing piece 210 is bored main body 211 inner surface with band and is contacted, and pressure sleeve 212 bores main body 211 interlock by screw 2 213 and band; Adjusting nut 208 is threaded connection in band cone main body 211, forming between adjusting nut 208, band cone main body 211, pressure sleeve and main shaft 216 can the chamber of axial stretching, this chamber is built-in has plenty of axle sleeve 1, axle sleeve 2 205, dish-shaped shell fragment 1, dish-shaped shell fragment 2 207, internal friction sheet 209, outer wearing piece 210, main shaft 216 carries out axial location by internal friction sheet 209, to ensure that main shaft 216 does not offset by middle shaft rotation.As the Z-type quick change collet chuck 220 of the excessive chuck in outside, logical slip sliding sleeve head 201 is inserted in main shaft 216, is located by steel ball 5 202, causes Z-type quick change to press from both sides cylinder 220 and main shaft 216 interlock.If internal friction sheet 209 and main shaft 16 friction are F1, it is F2 that outer wearing piece 210 bores main body 211 friction with band, the moment of torsion of drill bit or screw tap is for being F3, manual operation operation rotating adjusting nut 208 is advanced to band cone main body 211 direction spiral, dish shell fragment 1 and the stressed change shape of dish-shaped shell fragment two and compressing, increase F1 and F2, when being with cone main body 211 in high tape travel, when being less than F1 and F2 sum from drill bit or screw tap by the drag moment of torsion F3 that Z-type quick change collet chuck 220 passes to main shaft 216, main shaft 216 bores main body 211 run-in synchronism with band, when F3 is greater than F1 and F2 sum, main shaft 216 skids even slack, the Z-type quick change collet chuck 220 of interlock and screw tap drill bit also do corresponding actions state thereupon, thus can not because of the excessive harm causing screw tap drill head rupture of F3, reach the object of protection screw tap drill bit.Z-type bore attack combination chuck internal friction sheet 209 coordinate with outer wearing piece 210 profile of tooth, locate not smart, between internal friction sheet 209 and main shaft 216, outer wearing piece 210 and band bore between main body easy to wear, main shaft 216 center line is caused to depart from band cone main body 211 center line, the remote-effects positioning precision of screw tap drill bit, add wonderful works drag F3, directly shorten the screw tap drill bit operating period; Owing to not establishing the point of accumulation of opposing moment of torsion, adjusting nut 208 is from zero-bit, and empirically manual adjustment is to required torque resistant position, and governing speed is slow; Attack combination chuck volume greatly because Z-type bores, be only suitable for the feeding main shaft of main equipment, there is limitation in the supporting application of mini-plant.
See Fig. 2, a kind of S type bores attacks combination chuck, wherein sliding sleeve head 301 is placed in outside band cone main shaft 302, snap ring 3 310 is in case on-slip pullover 301 comes off, slip lid 303 is by screw 2 306 positioning belt cone main shaft 302, inner also equal six the stripe shape grooves of band cone main shaft 302, groove is built-in with block rubber 305, and slide block 304 is carried out by Elastip pin 307 and block rubber 305 and is flexible coupling.Manual operation sliding sleeve head 301, overcomes the elastic force of reset function spring 4 308, steel ball 7 309 to move outside axis normal direction, S type quick change collet chuck 311 is inserted band cone main shaft 302 in, S type quick change collet chuck 311 top six-sided structure contacts with slide block 304 is supporting.When the drag moment of torsion suffered by S type quick change collet chuck is excessive or stressed frequency change, rely on block rubber to produce the change of being out of shape and regulating drag because of stressed, reduce screw tap drill bit drag change frequency, to reach the object of protection screw tap drill bit.Suffered torsion compensates the deflection depending on block rubber, places restrictions on rubber deformation amount in specific space, thus torsion compensation is placed restrictions on simultaneously; S type brill is attacked combination chuck and be there is volume equally greatly, is only suitable for the feeding main shaft of main equipment, there is limitation in the supporting application of mini-plant.
Bore based on above-mentioned Z-type and attack combination chuck with S type bores the deficiency of attacking combination chuck, solve flexible overload protection fixture not smart to screw tap drill bit location, be difficult to manipulation adjustment, the excessive limitation problem being not suitable with mini-plant of volume becomes must.Be necessary to provide a kind of fine-tuning brill newly to attack dual-purpose shield jig for this reason; not smart to solve existing flexible overload protection fixture location, be difficult to the problem regulated, be applicable to mini-plant field simultaneously; screw tap drill bit is used, the object of stabilized product quality to reach protection and to extend.
