Description
Technical field
The invention belongs to numerical control machine tool technique fields more particularly to a kind of processing of numerically-controlled machine tool to use collet.
Background technique
Numerically-controlled machine tool is the abbreviation of numerically-controlled machine tool, is a kind of automated machine tool equipped with program control system.The control
System processed, which can be handled logically, has control coding or other symbolic instruction regulated procedures, and is decoded, with code
Digital representation, numerical control device is inputted by information carrier.Various control signals are issued by numerical control device through calculation process, are controlled
The movement of lathe, shape and size by drawing, automatically processes part.Numerically-controlled machine tool preferably solves multiple
Miscellaneous, accurate, small mount, multi items part processing problems are a kind of flexible, dynamical automated machine tools, represent existing
It is a kind of typical electromechanical integrated product for the developing direction of Machine-Tool Control technology.
A kind of important accessory of the collet as numerically-controlled machine tool, is mostly installed in numerical control machine tool chuck, as clamping cutter
Component use.In the prior art, numerically-controlled machine tool collet is to be not available for adjusting after mounting, between cutter and main shaft of numerical control machine tool
It is whole, and when processing the workpiece of some distinctive appearance structures, need to adjust the relative position between cutter and workpiece, therefore
It is inconvenient in adjustment process.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of numerically-controlled machine tool processing collet, collet is realized
The automatic adjustment in two different location directions, without manually adjusting, so that easy to adjust, quick.
Base case of the invention: a kind of numerically-controlled machine tool processing collet, including clamp head piece, collet axis, collet sleeve and peace
Axis is filled, the collet axis is horizontally arranged in collet sleeve by bearing, one end connecting clip part of the collet axis, the collet
The other end of axis is connected with the first telescopic shaft；The installation axle is in axial direction respectively equipped with support column, stepper motor and control
Device, the collet sleeve are fixed on the top of support column, and the output shaft of the stepper motor is towards the direction of support column, the stepping
The output end of motor is connected with driving gear, is engaged with the first driven gear and above and below the driving gear respectively

Open state, the second connector 19 and the second telescopic shaft 23 are also at off-state.Stepper motor 15 just drives driving tooth after starting
14 rotation of wheel, the rotation of driving gear 14 drive crank 26 to rotate, and the band piston 30 under the rotation of crank 26 of horizon bar 27 is being propped up
Left and right moves back and forth in strut.Support column 37 can internally inject water by the first water inlet 34, when piston 30 is moved to the left,
28 air-breathing of air inlet of support column 37, at the same piston 30 water in support column 37 can gradually be squeezed into outlet pipe 36, water again from
It is flowed out in outlet pipe 36, rinses clamp head piece 1 and cutter, then flow into collecting-tank 32, filter screen 33 is used for the water after filtration and washing
Middle had processing debris, the water for flowing into collecting-tank 32 pass through water inlet pipe 31 again and enter in support column 37.When piston 30 to
When moving left, piston 30 can gradually squeeze into the gas that 37 inside right chamber of support column sucks in escape pipe 5 from gas outlet 29, gas
It is blown out from escape pipe 5 again, effectively blows away the processing debris of clamp head piece 1 and cutter, debris easy to process can follow water together
It washes away.I.e. in the collet of this programme, when stepper motor 15 drives driving gear 14 to rotate, clip position side can not only be realized
To adjusting, additionally it is possible to realize the cleaning of clamp head piece 1 and cutter.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
