Description
Technical field
This utility model relates to drilling attachment in a kind of hardware & tools, specifically one and matches with electric drill working-spindle
Certainly impact clamp drill clamping head.
Background technology
Existing impact drill chuck is typically made up of drill body, jaw, screw, nut sleeve, overcoat, spring, jump ring, bonnet,
Three jaws are separately mounted in three decile inclined holes of drill body, and screw is arranged in the screw groove of drill body, screw and jaw
Screw thread forms thread transmission, and nut sleeve is fixing with screw to be connected, and overcoat leading inside is provided with impact projection, nut sleeve front end
Face is provided with collision projection, and overcoat back end inner circumference arranges a jump-ring slot, bonnet and overcoat endoporus matched in clearance, blocked by jump ring,
Installing spring between bonnet and drill body, spring is dish-style spring, after be stamped gap and be enclosed within drill body, spring supporting bonnet, bonnet
Compression spring can be axial movement, jump ring is stuck in the groove of overcoat, and drill body rear portion has screwed hole and six side's connecting rods to be connected
Connect.When installing and using, the connecting rod at drill body rear portion is connected with the power transmission shaft of power equipment, drives drill body to drive during drive axis
Three-jaw and folded instrument synchronous axial system.Holding with a hand overcoat, electric drill rotates forward, and drill body and jaw and then rotate, overcoat and screw phase
Not rotating drill body, the screw thread of jaw closes along the screw thread rotation of screw, when after jaw clamping tool, and screw, nut sleeve, folder
Pawl rotates together with drill body, and overcoat does not rotates, the impact projection in overcoat and the collision projection Contact-impact on nut sleeve, two
Protruding Dou You inclined-plane, side, the collision that the impact projection of overcoat is axially moved across nut sleeve is protruding, and spring is compressed, and crosses
After projection, by the pulling force of spring, the impact projection in overcoat again falls into nut sleeve front end face, carries out subsequent cycle, often clash into
Once, to one rotary torsion of screw, screw screw thread promotes jaw clamping tool.Above-mentioned impact drill chuck structure is complicated, processing
Cost is high.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, it is provided that a kind of structure letter
Single, easy for operation, assemble reliable and stable, what processing cost was low impacts clamp drill clamping head certainly.
The technical scheme in the invention for solving the above technical problem is: a kind of from impacting clamp drill clamping head, its bag
Including drill body, jaw, screw, nut sleeve, overcoat, spring, jump ring, bonnet, three jaws are separately mounted to three deciles of drill body
In inclined hole, screw is arranged in the screw groove of drill body, and screw forms thread transmission, nut sleeve and screw with the screw thread of jaw
Fixing connection, overcoat leading inside is provided with impact projection backward, and nut sleeve front end face is provided with collision projection, it is characterised in that: institute
Stating bonnet to be fixed on drill body, jump ring is stuck in overcoat, and described spring is arranged between nut sleeve rear end face and jump ring.
Further, described spring is cylindrical spiral spring, and its cylinder cylindrical relies on overcoat endoporus radially location.
Further, described impact is protruding and the protruding side of collision is provided with excessive inclined-plane.
Further, described jump ring is arranged in the jump-ring slot of jacket internal.
Further, described bonnet is fixing with drill body to be connected, bonnet and overcoat matched in clearance.
When this utility model uses, when needs clamping tool, grasping overcoat, electric drill rotates forward, and jaw is to instrument side
To clamping, after clamping instrument, drill body rotates together with screw, and overcoat is motionless, the impact projection of overcoat leading inside and nut sleeve
On collision projection Contact-impact, there is excessive inclined-plane two protruding sides, and the impact projection of overcoat is axially moved across silk
The collision of mother set is protruding, and spring is compressed, and after crossing projection, relies on the effect of spring, and the impact projection in overcoat falls into again
On nut sleeve front plan.Then carrying out subsequent cycle, often clash into, to one rotary torsion of screw, screw screw thread promotes
Jaw clamping tool.Against existing technologies, this utility model circulation impact, screw is often impacted once, and clamping tool once, reaches
Purpose to Automatic-clamping instrument.Its simple in construction, easy for operation, to assemble reliable and stable, processing cost is low, is a kind of reason
That thinks impacts clamp drill clamping head certainly.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described further.
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model structure partition schematic diagram.
Label in figure is: 1. drill body, 2. overcoat, 3. screw, 4. jaw, 5. nut sleeve, 6. spring, 7. jump ring, 8. after
Lid, 21. impact projections, 51. collision projections.
Detailed description of the invention
It can be seen that this utility model is a kind of from impacting clamp drill clamping head from Fig. 1 and Fig. 2, it includes drill body 1, overcoat
2, screw 3, jaw 4, nut sleeve 5, spring 6, jump ring 7, bonnet 8 etc..Three jaws 4 are separately mounted to three deciles of drill body 1
In inclined hole, screw 3 is arranged in the screw groove of drill body 1, and the screw thread of screw 3 and jaw 4 forms thread transmission, overcoat 2 with
Nut sleeve 5 relatively rotates, and nut sleeve 5 is fixed on screw 3.Described bonnet 8 is fixed on drill body 1, and the relative drill body 1 of bonnet 8 is not
Rotate.Bonnet 8 is arranged on rear portion in overcoat 2, with overcoat 2 matched in clearance.Described bonnet 8 can be sheet stamping member or nylon
Part, it is easy to machine-shaping.Jump ring 7 is stuck in overcoat 2, in specifically jump ring 7 is stuck in the inner side jump-ring slot of overcoat 2.Described overcoat 2
Leading inside is provided with impact protruding 21 backward, and nut sleeve 5 front end face is provided with collision protruding 51, the impact of overcoat 2 protruding 21 and silk
The collision projection 51 of mother set 5 staggers adjacent.Described impact protruding 21 and protruding 51 sides of collision are provided with excessive inclined-plane.Described spring
6 are arranged between nut sleeve 5 rear end face and jump ring 7.
Further, described spring 6 is cylindrical spiral spring, and its cylinder cylindrical relies on overcoat 2 endoporus radially location.
When this utility model uses, when needs clamping tool, grasping overcoat 2, electric drill rotates forward, and jaw is to instrument side
To clamping, after clamping instrument, drill body rotates together with screw, and overcoat is motionless.Electric drill rotates forward, and the impact of overcoat 2 protruding 21 is clashed into
Promoting the collision projection 51 on nut sleeve 5, two protruding Dou You inclined-planes, side, impact protruding 21 is oblique along collision protruding 51
Face rises, and overcoat 2 moves axially, and the spring 6 in overcoat 2 shrinks, and relies on the thrust of electric drill, after collision protruding 51 crossed by overcoat 2,
Relying on the effect of spring, the axial return of overcoat 2, the impact projection in overcoat falls on nut sleeve front plan again.Circulating flushing
Hitting, nut sleeve 5 drives screw 3 to rotate, and screw 3 is often impacted once, promotes jaw 4, and clamping tool is once.Reach Automatic-clamping
The purpose of instrument.
This utility model is simple and reasonable, easy for operation, is a kind of lightweight from impacting clamp drill clamping head.
