Detailed description of the invention
The detailed description novel about this and technology contents, coordinate graphic being described as follows, but institute's accompanying drawings only provide ginseng Examine and use is described, being not used for this novel person of being any limitation as.
Referring to shown in Fig. 1, the tailstock driving means of this kind of lathe of novel offer, Fig. 1 is that this Novel tailstock controls dress Putting the combination schematic diagram being installed in lathe, it essentially consists in: lathe comprises a table 10 and both sides are provided with a spindle drum 20, Tailstock 30 and couple a slide track seat 40 of tailstock 30, tailstock 30 is configured with the multiple cutters (31,32) for carrying out interior hole machined, Such as drill bit of inner bolt hole processing, or the cutter of screw tapping etc., and lathe configures between spindle drum 20 and tailstock 30 There is a cutter tower seat (not shown), and the front of lathe controls device corresponding to being provided with a driving means 50 and at spindle drum 10 60;Wherein the power of lathe can be provided by motor, and is from top to bottom provided with track 11 outside table 10.
From the above, spindle drum 20 comprises a power transmission shaft (not shown) of a chuck 21 and connecting clip, this power transmission shaft (figure Do not show) driven by above-mentioned driving means 50 and drive chuck 21 to rotate, chuck 21 is available for clamping a workpiece S;And slide track seat 40 Bottom is corresponding to being provided with chute (not shown), so that tailstock 30 can be in track by slide track seat 40 at the track 11 of table 10 Sliding back and forth on 11.
Coordinating refering to shown in Fig. 2 to Fig. 4, this novel cutter driving device is this novel technical characteristic institute the most simultaneously , control driving means 50 by the control device 60 being configured in lathe, and be configured at the driver near tailstock 30 Structure 70, the cutter (31,32) rotating to order about spindle drum 20 respectively, ordering about on tailstock 30 towards the propelling of spindle drum 20 direction or drives The cutter (31,32) on tailstock 30 is made to rotate to carry out interior hole machined operation.
From the above, driving means 50 includes two independent driving assemblies, its be a main shaft drives assembly 51 and One cutter drives assembly 52, and main shaft drives assembly 51 comprises the main motor of be located in lathe 511 and transmission component (is schemed not Show), such as power transmission shaft, gear, driving belt etc., the most main motor 511 is selected from a d.c. motor or an alternating current motor;Preferably Ground, it is a d.c. motor and is electrically connected with and controls device 60 and rotate with drive shaft seat 20, so that the processing on chuck 21 Thing S rotates, and drive mechanism 70 comprises a push broach unit (not shown), a tool changing unit (not shown) and a power transmission shaft, and (figure is not Show), heap cutter unit moves towards working substance S along radial path L in order to the cutter of pushing and withstanding correspondence working substance S, and tool changing unit group connects Each cutter (31,32) converts cutter 31 or the cutter 32 of corresponding working substance S with round robin, and power transmission shaft power connects cutter Tool drives assembly 52 to rotate to order about cutter (31,32).
From the above, cutter drives assembly 52 is then driven by another independent adjustable speed motor 521;By table 10 Outside group sets a fixed plate 520, the such as set of locations outside slide track seat 40 and sets fixed plate 520, and fixed plate 520 is provided with screw Being fixed in outside lathe with screwed lock for cutter drives assembly 52, wherein this adjustable speed motor 521 is a servo motor (Servo Motor), such as DC servomotor, permanent magnetic Ac servo motor or sensing AC servomotor, it is not intended at this;And cutter Tool drives assembly 52 to further include belt pulley 522 and the driving belt 523 connecting aforementioned servo motor, driving belt 523 with Drive mechanism 70 power connects and rotates ordering about cutter 31, such as in order to the drill bit of interior hole machined, and servo motor is electrically connected with Control device 60, to provide motor power or to connect an external power supply, such as electromotor, be not intended at this.
Control device 60 and include the (not shown) such as switch handle, shift knob, Touch Screen, use and carry out assembly action Control, and control device 60 and more can include an operation interface (not shown) and carry out processor setting and a control for operator Device 60 processed is electrically connected with driving means 50, as controlling its running and coordinating its operational relationship.
When carrying out interior hole machined operation, the side in the corresponding working substance S of tailstock 30 can install the cutter 31 of correspondence, and leads to The operation interface crossing control device 60 is processed travel settings, sets main shaft drives assembly 51 and cutter according to processor Drive assembly 52 to rotate with drive shaft seat 20 respectively, promote corresponding cutter to advance towards working substance S, simultaneously, be external in car Adjustable speed motor 521 outside Chuan rotates, and is revolved to order about cutter 31 by belt pulley 521, driving belt 522 and drive mechanism 70 Turn, so that working substance S is carried out interior hole machined.
From the above, utilize servo motor as the rotating driving device of interior aperture knife tool because of the high response of servo motor Speed, can reach high rotating speed in very short time, and the speed operating range of servo motor is the broadest, about can reach 3000rpm~5000rpm and its transient torque can reach 3~5 times of nominal torque, so portion can be because of speed when speed adjusts Relation and make torque change, and servo motor select positioning precision can be between ± 0.05 °~± 0.1 °, can be effective It is reduced to the high attrition rate of the caused driving belt of transmission 522 during interior hole machined operation, although and servo motor is frequent in height Short distance be set to and have location and adjust and produce the problem rocked, but in order to as the instrument (31,32) of hole machined in driving Cutter rotate on, aforesaid problem then will not affect, furthermore is external in the cutter drives assembly 52 outside lathe, operation Personnel can disassemble without complete machine at any time, directly can carry out the replacing of driving belt 522, the maintenance of servo motor or more in outside Change, inspection side or the time of maintenance can be greatly decreased.
In sum, the cutter driving device of this novel lathe, really can reach intended application target, and solve known Disappearance, again because of great novelty and progressive, comply fully with new patent application important document, filing an application according to Patent Law in whence, respects Please detailed survey grant quasi-this case patent, to ensure the right of creator.
