Description
Technical field
The utility model is related to a kind of threading tool, and in particular to a kind of flexible tapping cutter.
Background technology
During current construction machinery industry work in-process heart processing minor diameter screwed hole, generally using radial drilling machine, processing effect
Rate is low, processes the of poor quality of rear thread hole, and Ye You producers carry out rigid tapping on Digit Control Machine Tool, because rigid tapping main shaft is fixed
Position high precision, processing workpiece need to have good rigidity, can otherwise produce processing rebound phenomenon, cause screwed hole unrest tooth, or even
Break screw tap；Also there are some producers to use the semi-flexible tapping with flexible chuck, to protect screwed hole and screw tap, but protected by overload
The limitation of moment of torsion is protected, process is easily stopped, cannot still solve the problems, such as weak rigid structural member tapping processing resilience.
Utility model content
It is to solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of simple structure, high in machining efficiency,
The flexible tapping cutter of highly versatile.
In order to realize above-mentioned target, the utility model is adopted the following technical scheme that：
A kind of flexible tapping cutter, including handle of a knife, knife bar, tool rest and cutter head, the knife bar include knife pipe and sliding axle, knife
One end of pipe is connected with handle of a knife, and the other end is the accent of knife pipe internal cavity, and tube wall is provided with axial slide；The knife pipe and sliding axle
Socket, is provided with spring in cavity；One end of the sliding axle is provided with the tool rest of connection cutter head, and the side of the other end is provided with and chute
The slide bar of matching；The sliding axle is slided along chute by slide bar in the cavity of knife pipe.
The tired damage of the tube wall of above-mentioned chute insertion knife pipe, the convenient working condition from external observation sliding axle, and spring.
The two ends closure of above-mentioned chute, when preventing cutter from rotating, the sliding axle for connecting tool rest comes off.
The two ends of above-mentioned spring connect handle of a knife and sliding axle by threaded block respectively, and spring is axially for sliding axle provides bullet
Power, circumferencial direction can be rotated by Luo Wei with sliding axle.
Above-mentioned slide bar is screwed onto the side of sliding axle.Slide bar and the spiro connection structure of sliding axle, facilitate sliding shaft sleeve to be connected on knife
In pipe, and slide bar plays knife pipe and rotates the power gearing for driving sliding axle to rotate.
The length of above-mentioned spring is the 1/3-2/3 of cavity length so that the sliding axle of connection cutter head is in the cavity of knife pipe
There is the spacing stretched by spring force；When cutter just turns on screw thread, sliding axle gos deep into screw, and spring provides pressure for sliding axle
Power, when cutter is inverted, spring provides pulling force for sliding axle.
It is of the present utility model to be beneficial in that：A kind of flexible tapping cutter that the utility model is provided, knife pipe is by sky
Chamber is socketed sliding axle, by the chute of knife tube wall so that sliding axle can slide axially along chute, can be seen in real time through chute
Examine the axially loaded situation of knife pipe and sliding axle, and cavity inner spring tired damage degree；It is screwed onto the slide bar limitation of knife pipe end side wall
Sliding axle it is circumferentially displaced, meanwhile, knife pipe rotates sliding axle by slide bar, drives cutter head.Flexible tapping of the present utility model
Cutter uses telescopic attachment structure, simple structure, low manufacture cost, highly versatile, is particularly suited for weak rigid workpiece, small straight
The tapping of footpath screwed hole, by the elastic force of spring, solves the problems, such as weak rigid structural member processing resilience backlash compensation, relative to industry
The radial drilling machine thread mill drilling for inside commonly using, has the advantages that high in machining efficiency, hole processing quality is good.
Brief description of the drawings
Fig. 1 is a kind of structural representation of flexible tapping cutter of the present utility model.
The implication marked in accompanying drawing is as follows：
1st, handle of a knife, 2, knife pipe, 3, sliding axle, 4, tool rest, 5, cutter head, 6, spring, 7, chute, 8, slide bar.
Specific embodiment
Make specific introduction to the utility model below in conjunction with the drawings and specific embodiments.
A kind of flexible tapping cutter, including the handle of a knife 1 for constituting is socketed by sliding axle 3 and knife pipe 2, the end of sliding axle 3 is provided with
The tool rest 4 of cutter head 5 is connect, the end of knife pipe 2 connects handle of a knife 1.
The tube wall of knife pipe 2 is provided with penetrating tube wall, and the axial slide 7 that two ends close.
Sliding axle 3 is fixed in the cavity of built-in spring 6 by being screwed onto the screw rod of side wall, and along chute 7 axially
Slide.
The two ends of spring 6 connect handle of a knife 1 and sliding axle 3 respectively by threaded block, and the length of spring 6 is the 1/ of cavity length
2。
When using, flexible tapping cutter is attached on machine tool chief axis by handle of a knife 1, machine tool chief axis are rotated and push handle of a knife 1,
Circumferentially rotated by the linkage cutter head 5 of slide bar 8 in chute 7, and the cutter head 5 of the end of sliding axle 3 is axially pushed by spring 6.
The screw tap of cutter head 5 resign oneself to a loss part be hung into thread Pilot hole after, cutter head 5 with cutter rotation along screwed hole go deep into.
For the thread pitch that weak rigid material material causes, cutter head 5 is slided along chute 7 and is adjusted according to stress,
The floating compensation to gap for completing in real time.
After tapping terminates, machine tool chief axis reversion, the band cantilevered out screwed hole of cutter, cutter head 5 is inverted out along screw thread, cutter head 5
During producing, spring 6 is continuously cutter head 5 and provides elastic force, has further avoided because of the screw thread that material-structure part resilience brings
Hole unrest tooth, screw tap damaging problem.
General principle of the present utility model, principal character and advantage has been shown and described above.The technical staff of the industry
It should be appreciated that above-described embodiment does not limit the utility model in any form, it is all by the way of equivalent or equivalent transformation
The technical scheme for being obtained, all falls within protection domain of the present utility model.
