Description

The numerical control car digs the rotor lathe

The utility model relates to a kind of special purpose machine tool, belongs to a kind of numerical control car plane rotor lathe that is used to repair traction electric machine rotor commutator outer round surface, mica slot.

Along with the needs of railway speed increase development, and internal combustion and electric locomotive are more and more universal, and just the tooling device that internal combustion, electric locomotive are keeped in repair is had higher requirement.Especially the commutator of traction electric machine rotor because of its precision prescribed height, is decided inspection at every turn and all will be repaired, and needs turning, carves mica slot and chamfering down, each locomotive depot adopts basically be car commutator cylindrical operation with quarter down mica slot operation and chamfering process separate and carry out.Under when carving mica slot, calibration is controlled by workman's sensation and qualification, is difficult to guarantee crudy.The processing of commutator cylindrical needs smooth turning lathe of special outfit and undercutter, and is by artificial chamfering, and these have all increased equipment investment, and processing and loading and unloading amount.

The purpose of this utility model provides an a kind of clamping can finish the following quarter of the turning of commutator outer round surface, mica slot and the numerical control car plane rotor lathe of chamfering.

The purpose of this utility model is to realize like this, it comprises lathe bed, control cabinet, numerical control case, comprise that also lathe bed one end dress plays the main spindle box of calibration effect when being used to tighten workpiece and channeling, lathe bed other end dress is used to hold out against the tailstock of workpiece and is used for the tailstock guiding mechanism of distance between mobile tailstock, adjustment main spindle box and the tailstock, infeed mean is cut in entrucking on the wing base of a side of lathe bed other end configuration, be equipped with on the tailstock and be used for carving down mica slot, the channeling device of chamfering respectively is equipped with carriage on the lathe bed of main spindle box front end and tailstock front end.

Because the utility model collection car digs and to be processed as one, therefore can replace smooth turning lathe and undercutter, can save equipment purchasing and invest that half is many; Because multifunctionality of the present utility model makes the commutator reparation reduce lifting clamping times and alignment error, therefore not only can guarantee crudy, also can raise labour efficiency; Because automatic indexing of the present utility model has replaced artificial calibration, therefore alleviated working strength of workers; Because the utility model adopted the three-phase brush motor, have therefore that speed adjustable range is wide, starting performance good, the power-factor of load and efficient height, speed is regulated meticulous.

mean 18 is that dress knife rest 5 is formed on the slide unit 4 by dress slide unit 4 on the wing base 31.Second stepper motor 8 is by being bolted on the slide unit 4, and gives leading screw, screw by shaft coupling with the motion transmission of motor, the knife rest 5 that is installed on the slide unit 4 vertically moved, thereby realized vertical self-acting feed of lathe.Laterally moving of knife rest 5 is by manual control, and the cutter platform on the knife rest 5 is used for installing the turning cutter.With reference to Fig. 3, sleeved 30 in the tailstock 9, sleeve 30 and tailstock 9 movingly, it is top 32 that barrel forward end is equipped with, and is used for holding out against workpiece, and keep workpiece on the center line of main shaft 17 and tailstock 9.Dress tailstock screw 34 in the sleeve 30, tailstock screw mandrel 33 places tail spindle bearing 35, and tailstock screw mandrel 33 rear ends are connected with handwheel 14, shake handwheel 14 and drive tailstock screw mandrel 33, and tailstock screw 34 makes sleeve 30 move around for 9 li at tailstock, and control sleeve 30 stretches out length.Right-hand member at lathe bed 25 also is equipped with the tailstock guiding mechanism, adjusts screw mandrel 29 and adjusts screw 28 and forms by being contained in to be equipped with on the support of bearing 22 on the lathe bed 25, the support of bearing, is used for mobile tailstock, so that the distance between adjustment main spindle box 3 and the tailstock 9.On the lathe bed 25 of tailstock 9 front ends, carriage 19 is housed, lifting the time can earlier workpiece be placed on carriage 19,19 ' on, damage chuck 13 and tailstock 9 is top 32 when avoiding workpiece to fall, so that workpiece is installed.Lathe bed 25 holds together parts such as main spindle box 3, tailstock 9, wing base 31, the preceding top and back centre 32 that be contained in the barrel of tail stock that assurance is contained in the spindle taper hole is contour, and guarantees to be contained in slide unit 4 on the wing base 31 and vertically move the depth of parallelism to the top center line in front and back.Channeling device 24 is adorned ram 23 in channeling housing 7, ram 23 and channeling housing 7 are movingly, ram 23 stretches out the front end dress floating tool holder 6 and the fine setting screw mandrel of channeling housing 7, dress stroke screw 27 and stroke screw mandrel 26 in ram 23, stroke screw mandrel 26 rear ends are connected with 11 of the 3rd stepper motors, the 3rd stepper motor 11 drives stroke screw mandrel 26, stroke screw 27, makes ram 23 make reciprocal stroke movement in channeling housing 7.With reference to Fig. 4,5, floating tool holder 6 is by horizontal knife rest 37, and rail head 38 is finely tuned parts such as screw mandrel 44 and cydariform bearing pin 43 and formed.The cutter holder 36 of floating tool holder front end is connected with horizontal knife rest 37 by cydariform bearing pin 43, and and laterally leaves the gap between the knife rest 37.Laterally knife rest 37 horizontal amount of movements determine that by mobile scale 42 mobile scale 42 is fixed on the rail head

is connected with the silk hole of horizontal knife rest 37, when fine setting screw mandrel 44 devices are used for having bigger error between adjacent mica slot, makes floating tool holder do horizontal the adjustment.Transmission system of the present utility model makes the digital control system by the control cabinet 12 of main motor and number control cabinet 10, control the gyration of main shaft 17 respectively, the dividing movement of the lengthwise movement of turning, the reciprocating motion of planing and main shaft 17 is with the stepless speed regulation of realization main shaft 17 and the semi-automatic feeding of turning, planing and calibration.Main motor adopts the three-phase brush motor, and first stepper motor, second stepper motor 8, the 3rd stepper motor 11 all adopt decelerating step motor, and be connected with numerical control case 10 by lead.Its operation principle: according to the processing technology of rotor commutator, need the cylindrical of rough turn commutator earlier, at first transposition handle 2 is pulled to disengaged position, again clutch 1 handle wrench to the position of engagement, start main driven by motor main shaft 17 rotations then, and start second stepper motor 8 on the slide units 4 by numerical control case 10 and drive knife rests 5 and vertically move, stroke and feed are by 10 programme-control of numerical control case.After rough turn, transposition handle 2 is pulled to the position of engagement, again clutch 1 handle wrench to disengaged position, start first stepper motor, second stepper motor 8 by numerical control case 10 then, drive main shaft 17 calibration of main spindle box 3 respectively, the channeling device is carved mica slot 24 times.Main shaft 17 per minute degree once after, floating tool holder 6 times is carved a slice mica slot or chamfering and is moved in circles and finish whole process of mica slot on the channeling device 24.Be the cylindrical of finish turning rotor commutator at last, the process operation process is the same with rough turn cylindrical, needs transposition handle 2 and clutch 1 handle are thrown off and the position of engagement, finishes process by 10 controls of numerical control case then.
