The specific embodiment in the face of the utility model describes down:
Referring to Fig. 2; A kind of numerical control squaring machine comprises lathe bed 8, is arranged on crossbeam 2 on the described lathe bed 8, is arranged on workbench 1 on the described crossbeam 2, is arranged on the table feed servomotor 9 of an end of described crossbeam 2, workbench rotational lead screw 10 that be connected with the output shaft of described table feed servomotor 9 and that match with nut on the workbench 1.Table feed servomotor 9 drives workbench 1 feeding through workbench rotational lead screw 10.
Referring to Fig. 1, Fig. 4, this numerical control squaring machine also comprises the ram 6, the knife rest rotating disk 3 that is arranged on the leading section of described ram 6 that are slidingly arranged on the described lathe bed 8, be arranged on sliding carriage 4 on the described knife rest rotating disk 3, be arranged on the knife rest feed servo motor 5 at the top of described sliding carriage 4, blade holder turns leading screw 27 that be connected with the output shaft of described knife rest feed servo motor 5 and that match with nut on the knife rest rotating disk 3.Knife rest feed servo motor 5 drives sliding carriage 4 feedings through blade holder turns leading screw 27.
Referring to Fig. 3, Fig. 4, this numerical control squaring machine also comprises the main shaft bearing 7 that is fixed on the described lathe bed 8, rotate the hollow spindle 22, the large helical gear 19 that is fixed on an end of described hollow spindle 22 that are arranged on described main shaft bearing 7 inner rings, be arranged on the described large helical gear 19 and the position can be along the top shoe 18 that radially carries out position adjustments of described large helical gear 19, be movably arranged on the big rocking bar 17 in the described lathe bed 8.Described top shoe 18 flexibly connects with the approximate mid-section of described big rocking bar 17 mutually; The top of described big rocking bar 17 is rotatably connected to fork fork 16; Described fork fork 16 is fixed on the described ram 6, and through handle 13, pressing plate 14 ram 6 is firmly connected with fork fork 16 mutually, is fixed with down balance staff 26 in the described lathe bed 8; Described balance staff 26 down flexibly connects with the bottom of described big rocking bar 17 mutually; When large helical gear 19 drove top shoe 18 rotations, top shoe 18 can drive big rocking bar 17 swings, moves forward and backward thereby drive ram 6 thus.Through regulating the distance between top shoe 18 to hollow spindle 22 axial lines, can reach the purpose of the stroke of regulating ram 6.
How to regulate the distance between the axial line of top shoe 18 and hollow spindle 22? Rotate in the described hollow spindle 22 and be provided with gear shaft 21; The axial line of described hollow spindle 22 overlaps with the axial line of gear shaft 21; Be fixed with second bevel gear 20 on the described gear shaft 21; Described large helical gear 19 is provided with first bevel gear 11 that is meshed with described second bevel gear 20; Also be provided with the leading screw 12 that is fixedly connected with described first bevel gear 11 on the described large helical gear 19, the internal thread that described leading screw 12 and top shoe 18 are had is threaded engagement mutually.Also being provided with embossing nut 24 on the described gear shaft 21 is used for described hollow spindle 22 is fixed on described gear shaft 21.When the part of machine tooling different size, when the stroke of described ram 6 need be done necessary adjustment, unclamp embossing nut 24; With special-purpose crank handle turning gear wheel shaft 21; Described gear shaft 21 drives 20 rotations of second bevel gear, and second bevel gear 20 drives 11 rotations of first bevel gear, and first bevel gear 11 drives leading screw 12 rotations; And then drive top shoe 18 and on leading screw 12, move, thereby reach the position of the axial line of adjusting the described relatively hollow spindle 22 of said top shoe 18.
Above-mentioned shaping machine is when work; After power passes to large helical gear 19 by main transmission; Described large helical gear 19 drives top shoe 18 and together rotates thereupon; The rotation of described top shoe 18 then drives big rocking bar 17 around balance staff 26 swings down, and the swing of described big rocking bar 17 then drives described ram 6 and does reciprocating linear motion through fork fork 16, connecting axle 15, pressing plate 14, handle 13.Also be fixed with cam disc 23 on the described hollow spindle 22, be fixed with near piece on the described cam disc 23, be provided with near switch 25 near piece is corresponding with described on the described main shaft bearing 7.The linear reciprocating motion of described ram 6 is consistent with the described 23 rotating cycles of cam disc; When described ram 6 after previous cutting movement is accomplished; Get back to the rearmost position; When being about to begin stock removal action next time, by be arranged near the described cam disc 23 near switch 25 sense on the described cam disc 23 near behind the piece, send a pulse command rapidly and give machine tool numerical control system; Digital control system is then controlled table feed servomotor 9 and 5 work of knife rest feed servo motor respectively according to the procedure of establishment in advance, to reach the purpose of machine cut processing feeding.
Referring to Fig. 6; Described near switch 25 and near the setting of piece; Make when described ram 6 is positioned on the extreme position of this numerical control shaping machine range; Described being near switch 25 sensed described position near piece, and this moment, the axial line near relative hollow spindle 22 between piece and the leading screw 12 had angle.Described near switch 25 and in a single day definite near the position of piece; When ram 6 is positioned on other arbitrary distance of run; Referring to Fig. 7, described near switch 25 detected ram 6 detectable limit position S0 (this moment leading screw 12 with near between the piece relatively the axial line of hollow spindle 22 have angle) relatively ram 6 practical limit position S (this moment leading screw 12 with rocking bar 17 is perpendicular greatly) deviation is arranged, and referring to Fig. 7; This moment, leading screw 12 was rotated counterclockwise; After detecting near piece near switch 25, leading screw 12 must rotate a low-angle again, and ram 6 just moves to extreme position.
At this; Two problems are described: the first, from mapping and Theoretical Calculation; Difference between detectable limit position S0 and the practical limit position S is less, and for the logical numerical control squaring machine of a Daepori, maximum deviation is probably within 3.5 centimetres; And in the whole stroke of ram 6 be not cutting always but the cutting before have one section sky to walk the stage---the depth of cut; General 5 centimetres to 10 cm range, be used to adjust ram 6 and reach initial velocity, thus the difference of S0 and S can not cause the planer feed time the relative workpiece of cutter hit cutter; When the second, planer is positioned at detectable limit position S0; Machine tool numerical control system promptly detects cutting feeding signal, control workbench 1 and 3 steppings of knife rest rotating disk; And ram 6 continues to slide to the right, after arriving practical limit position S, return, and so is provided with, and has reserved the enough feeding time, made it can accomplish complicated feeding for workbench 1 and knife rest rotating disk 3; And because workbench 1 and knife rest rotating disk 3 have the more feeding time (situation about coinciding with respect to detectable limit position S0 and practical limit position S); When cutting during softer workpiece, the depth of cut of ram 6 can suitably shorten, the feeding of also have enough time to finish the work platform 1 and knife rest rotating disk 3.And the utility model patent has obtained practical application, has obtained excellent effect.
