Description
Technical field
The utility model relates to mechanical chuck technical field, specifically a kind of firm drill chuck of locking.
Background technique
Drill chuck is very widely used in mechanical engineering, is primarily referred to as utilizing the machinery such as drilling machine, milling machine, lathe, boring machine
Process equipment carries out drilling and milling by the various drill bits of drill point head clamping, cutter.
Currently, common drill chuck has: manually fastened drill chuck；Self-locking type clamping head of hand-locking drill；Spanner drill chuck etc..They
Respectively there are advantage and disadvantage.But common fault is all that can not really clamp or self-locking, especially to larger specification drill bit.It is but difficult to after some locking
It unclamps, so that troublesome in poeration.Therefore, substantially 14 millimeters or more of drill bit can only use taper-shank drill.This bores miller skill to entire
Implementation makes troubles and wastes.
It discloses one kind in the Chinese patent that Authorization Notice No. is CN206794808U to rub poor locking drill chuck, the difference of rubbing
The upper end of the clamp of locking drill chuck is the connecting pin with lathe, and lower end is the clamping end of drill bit, and the lower end of clamp is at least three
Uniformly distributed cam ring chamber, the upper surface of each cam ring chamber, which is equipped with, leads slot；Clamping jaw and rolling element are sliding loaded in retainer, are loaded on
Follower spring in retainer pushes against cam ring A curved surface；The limit spring inserted in clamping jaw limits rolling element, clamping jaw upper end
Pin be slidably connected with slot is led；One end of torsional spring couples with clamp, and the other end couples with cover board；Cover board and driver plate respectively with rotation
Set connection, structure is simple, is not necessarily to locking accessory；The drill bit that changes the outfit is simply light, will not generate the operation injury of drill point and substantially mention
High efficiency；Locking is reliable, long service life, and drill bit zero slip does not hurt drill point and bit sub；Precision is higher, improves drilling quality；
All drill bit staight shanks can be simplified integrated artistic equipment.
But above-mentioned technical proposal there is problems in actual use: drill bit under fast state when stopping,
Since collet is suitble to driving mechanism to connect, the deceleration trend of collet is less than the deceleration trend of drill bit, that is to say, that
For collet in the state of soon stopping, drill bit also has the rotation trend greater than collet, therefore is easy to make between drill bit and collet
Force direction on the contrary, to be easy to cause drill bit fall off suddenly collet out the case where, damaged to drill bit.

It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
The concrete meaning of language in the present invention.
The technical solution of the patent is explained in further detail With reference to embodiment.
As shown in Figure 1-3, a kind of firm drill chuck of locking, including clamp 1, the top of clamp 1 are lathe connecting pin 11,
The lower part of clamp 1 is equipped with drill bit mounting hole, and installation cavity 2 is equipped in clamp 1, is equipped with several outside geneva mechanisms 3 in installation cavity 2
It is connect with the input terminal of train of reduction gears 4 by shaft with the output end of train of reduction gears 4, outside geneva mechanism 3, train of reduction gears
The gear engagement of 4 output is connected with rack-plate 5, and the end of rack-plate 5 is fixedly connected with the top clamping to drill bit 9
Grip block 7；Outside geneva mechanism 3 is made of cursor 31, the straight pin being connected on cursor 31 32 and outer groove-wheel 33, cursor
Actuator 12 is connected on 31, actuator 12 extends the outside of clamp 1；Train of reduction gears 4 includes passing through shaft and outer groove-wheel
The driving gear 41 of 33 connections engages with driving gear 41 gear wheel 42 connected and is connect by shaft with gear wheel 42 small
Gear 43, gear wheel 42 are the gear that the number of teeth is most in three gears, and pinion gear 43 engages connection with rack-plate 5；
Drill bit 9 is inserted into installation cavity by drill bit mounting hole, outside geneva mechanism 3 is driven, due to outside geneva mechanism 3
Output end is connect with the input terminal of train of reduction gears 4 by shaft, therefore the gear in train of reduction gears 4 is also rotated, and is subtracted
The gear of the output of fast gear set 4 drives grip block 7 mobile and carries out to the top of drill bit 9 to keep rack-plate 5 mobile
Clamping, (cursor 31 can be used as driving end to the characteristic due to outside geneva mechanism 3 with unidirectional drive, can drive outer groove-wheel 33
Rotation, but cannot be by outer groove-wheel 33 as driving end, if mechanism is for stuck state by outer groove-wheel 33 as driving end),
Therefore after grip block 7 carries out fastening clamp to the top of drill bit 9, the opposition of grip block 7 can not be moved grip block 7
Dynamic, 7 position of grip block is secured at this time, ensure that the locking effect to drill bit 9, since grip block 7 rotates and reverse folder to drill bit 9
Holding effect fruit be it is identical, make collet 9 that will not relatively rotate with grip block 7 when high-speed rotation state is stopped.
It should be strongly noted that Geneva mechanism is the prior art and conventional technical means of the art, and this
Any inventive improvements are not done yet to Geneva mechanism in application text, therefore repeat no more the drive of outside geneva mechanism 3 in the application text
The specific structure and principle of dynamic process.
Preferential, the top of drill bit 9 is the clamping part 8 of polygonal body shape, and grip block 7 is in and 8 side-anastomosis of clamping part
Shape；Polygonal body shape is made in clamping part 8, therefore can be played after contacting grip block 7 with 8 side of clamping part very well
Clamping effect and locking effect.
Further preferential, clamping part 8 is rectangular shape, and grip block 7 is U-shaped shape；Make the two sides inner wall of grip block 7
Just with the two sides outer wall of clamping part 8 is corresponding contacts, make the drill bit 9 of rotary state be difficult to relatively rotate with grip block 7.
The inner wall of installation cavity 2 is fixedly connected with sliding slot body 6, and rack-plate 5 is sliding to be loaded on sliding slot body 6, ensure that rack-plate 5 is mobile
Stability.
The top of installation cavity 2 offer with the consistent holding tank of the top shape of drill bit 9, be connected with magnet in holding tank
10；The top of drill bit 9 is inserted into holding tank, the locking ability to the drill bit 9 of rotation status, and magnet are further increased
10 are capable of the top of magnetic drill bit 9, so that falling suddenly for drill bit 9 is avoided when installing or removing drill bit 9, it is easy to use.
