Abstract
The utility model is flexible multi-functional quick-release clamping head, is a kind of pincers worker fixture.Replace existing tap wrench with the collet of flexible connection and quick despatch, to improve bench work efficiency, guarantees processing quality, and realize multifunctional working.This quick-release clamping head includes sleeve and tommy bar, and sleeve is provided with collet, claw is formed on collet, and collet is connected with quick-release rod piece, and tommy bar is housed on quick-release rod piece, constitutes complete collet.When work by machining tool such as drill bit, screw tap in the claw of collet, sleeve is tightened, tightens collet claw, pulling tommy bar can be processed.The utility model is used for the interior hole machined of various types, can be manual, and the interior hole machined under various operating conditions can be also carried out on lathe.
Description
Technical field
The utility model relates to pincers worker fixture, specifically a kind of flexible multi-functional quick-release clamping head.
Background technique
Pincers worker in manually operated interior hole machined be rigid structure common tap wrench, this tap wrench is in interior hole machined
In there are following defects：1, due to be single load bearing rigid structure, component easily snaps off in use；2, it has a single function, it can only
Manual operations cannot use on lathe, and working efficiency is low, and pole needs to improve.
Summary of the invention
To overcome defect existing for existing fixture, the utility model provides a kind of flexible multi-functional quick-release clamping head, to adapt to
The needs of bench work improve bench work efficiency, guarantee processing quality.
The technical solution of the utility model is as follows：Flexible multi-functional quick-release clamping head includes sleeve and tommy bar, and sleeve is provided with
Collet is formed with claw on collet, and collet is connected with quick-release rod piece, installs tommy bar on quick-release rod piece, constitutes complete quick-release clamping head.
Machining tool such as drill bit, screw tap are fitted into the claw of collet when work, tighten sleeve, tightening collet claw can be added
Work.
It is compared with existing tap wrench, the utility model has following beneficial effects：1, structure is simple, and manufacturing cost is cheap, is suitable for
Batch production；2, since collet and quick-release rod piece are clearance fits, there is therebetween slight oscillatory in when work, formed it is flexible even
It connects, effectively prevent causing overproof or tool the damage of workpiece in interior hole machined due to the hard contact of tool and workpiece；3,
Using face is wide, and mountable drill bit, screw tap, reamer etc. are accordingly processed in collet, embodies multi-functional feature；4, sleeve with
Collet is threadedly coupled, and collet is that square hole is connect with quick-release rod piece, is realized quick-detachment function, is saved the lay day, improves work effect
Rate；5, tommy bar is unloaded, by quick-release rod piece in the plurality of devices such as lathe, milling machine, bench drill, completes the machine under various process conditions
Tool processing, is widely applied.

Specific embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawing, flexible multi-functional quick-release clamping head is by collet 1, fast
Rod piece 2, tommy bar 3 and sleeve 4 is unloaded to constitute（As shown in Figure 1）, 1 leading portion of collet is cone, and conical section is formed with 4 claws 5（Such as
Shown in Fig. 2）, rear portion is cylindrical shape, and outer surface is formed with screw thread, and rear end is formed with square hole.4 leading portion of sleeve be taper, taper it is interior
The cooperation of the male cone (strobilus masculinus) of the conical surface and collet, back segment are cylindrical shape, and inner surface is formed with screw thread, the external screw thread cooperation of the screw thread and collet,
4 outer surface annular knurl of sleeve.Quick-release rod piece 2 is installed in the square hole of 1 rear end of collet, the preceding outside of quick-release rod piece 2 be it is rectangular, to
It is connected with collet 1, square face is formed with symmetrical two semicircle nests, places steel ball 6 in semicircle nest, makes quick-release rod piece 2 and folder
Larger gap is formed between head connection, realizes flexible connection, 2 rear portion of quick-release rod piece is formed with radial hole, installs tommy bar 3, quick-release in hole
2 rear end of rod piece is installation end, for installing on lathe.
When utility model works, used tool such as drill bit, screw tap, turn sleeve 4 are loaded onto the claw 5 of collet 1, are tightened
The elastic card claw 5 of collet 1, clamping tool pull tommy bar 3, and active force is passed to the tool on collet 1 by quick-release rod piece 2, real
Processing needed for existing.
The collet 1, sleeve 4 of the utility model make of alloy tool steel, and quick-release rod piece 2 and tommy bar 3 use structural carbon steel
Production, all parts turn blue processing.
