Description
Technical field
The invention belongs to mechanical field, in particular, relate to a kind of numerical control broaching tool processing inner spiral groove.
Background technology
Be with helicla flute endoporus to have in a lot of field to use widely, as the rifling of gun tube, the stabilizer etc. of rig, all the helicla flute of endoporus had higher requirements.But the difficulty in inner spiral groove processing all annoyings the production unit of spiral endoporus parts all the time.
Because the dependence of processing method to cutter of existing inner spiral hole is too high, make the cutter manufacture difficulty of processing inner spiral hole large, it adopts solid knife bar, on knife bar surface, fixing cutter head is set, make the processing technology of cutter complicated, and once tool wear, by the machining accuracy of very difficult guarantee workpiece; The maintenance of cutter and changing all needs whole knife bar to pull down just can be carried out afterwards, and therefore, difficult in maintenance, cost is also high.
Summary of the invention
The present invention is exactly for the problems referred to above, provides that a kind of structure is simple, the tool-broaching mechanism of broaching tool adjustable, removable digital control processing inner vortex.
For reaching above-mentioned purpose of the present invention, the present invention adopts following technical scheme, the present invention includes broaching tool and knife bar, cavity is provided with in knife bar described in its structural feature, knife bar surface is provided with the guide groove being communicated with cavity, is provided with carriage release lever, arranges rollered slideway in carriage release lever in cavity; One end of described broaching tool is provided with skewed slot, and broaching tool has the guide groove of one end through knife bar surface of skewed slot, and matches with the pulley in carriage release lever slideway; The end of described carriage release lever is connected by the same adjusting lever of screw thread; The end of described adjusting lever is stretched out by the end of knife bar.
Beneficial effect of the present invention: 1, the present invention fixes by the one end of adjusting lever being stretched out knife bar, then swivel knife carrier, at this moment, carriage release lever can because move by the reason of screw-threaded engagement with adjusting lever vertically; And the movement of the pulley on carriage release lever in skewed slot, make broaching tool in guide groove, do radial motion, achieve the adjustment of broaching tool position.Method of operating is simple, and adjustment easily; And precision also easily ensures.
2, due to design feature of the present invention, broaching tool of the present invention can carry out separately changing and safeguarding, without the need to whole broaching tool and knife bar being carried out safeguarding and overhauling simultaneously, reduces labour intensity, also saves the cost of broaching tool and knife bar.
3, the present invention is by changing different knife bars to realize the function changing angle and change number of cutters between cutter; The processing request that the head number of multiple inner spiral hole is different with cutting output can be met, applied widely.

Detailed description of the invention
The present invention includes broaching tool 5 and knife bar 6, be provided with cavity 3 in the knife bar 6 described in its structural feature, knife bar 6 surface is provided with the guide groove 16 being communicated with cavity 3, is provided with carriage release lever 4 in cavity 3, arranges the slideway 17 with pulley 10 in carriage release lever 4; One end of described broaching tool 5 is provided with skewed slot 9, and broaching tool 5 has the guide groove 16 of one end through knife bar 6 surface of skewed slot 9, and matches with the pulley 10 in carriage release lever 4 slideway 17; The end of described carriage release lever 4 is connected by the same adjusting lever 11 of screw thread; The end of described adjusting lever 11 is stretched out by the end of knife bar 6.
The present invention also comprises carriage release lever locking device 13, and described carriage release lever locking device 13 comprises cylinder 14 and claw 12, and one end that described claw 12 is stretched out by knife bar 6 with adjusting lever 11 is corresponding.
Two ends corresponding to carriage release lever 4 in the cavity 3 of knife bar 6 are provided with spacing shutoff 7; Prevent carriage release lever 4 displacement excessive, broaching tool 5 is come off.
Described spacing shutoff 7 is fixed in the cavity 3 of knife bar 6 by expansion sleeve 8.
Carriage release lever locking device 13 can be arranged in the groove of lathe bed 15, and during processing parts, claw 12 is hidden in groove, does not affect the normal work of broaching tool 5 and knife bar 6; When needing adjustment broaching tool 5, claw 12 is driven to rise to adjusting lever 11 position by cylinder 14.
Below in conjunction with accompanying drawing, one-off process of the present invention is described: during use, suitable knife bar 6 is connected with the servomotor 2 on lathe bed 15 slide plate 1 by expansion sleeve 8; Risen by cylinder 14 by the claw 12 of carriage release lever locking device 13, the adjusting lever 11 with knife bar 6 one end combines, and servomotor 2 rotates; Now adjusting lever 11 is motionless, and knife bar 6 drives carriage release lever 4 to rotate, and by the screw thread of engagement between carriage release lever 4 and adjusting lever 11, carriage release lever 4 is moved axially; Because the pulley 10 of carriage release lever 4 is in the skewed slot 9 of broaching tool 5, move axially with carriage release lever 4, make broaching tool 5 under guide groove 16 acting in conjunction of pulley 10 and knife bar 6, radially move, reach the object of adjustment broaching tool 5 position.
After adjusting broaching tool 5 position, move adjusting lever 11 is separated with claw 12 after slide plate 1, make decline return in the groove of lathe bed 15 by the cylinder 14 of carriage release lever locking device 13, broaching tool 5 and knife bar 6 can normally machined workpiece.
When needing to change broaching tool 5, only carriage release lever 4 need be moved to one end, after pulley 10 moves out the skewed slot of broaching tool 5, broaching tool 5 is in the slideway 17 of carriage release lever 4, broaching tool 5 can be extracted out by guide groove 16, and it is convenient to change.
