Background technology
In the existing machine tool axis system, main shaft does not have boosting system, and the original power output by motor satisfies main shaft moment output requirement merely, and the major diameter cutterhead can not be installed, and topology layout often occurs with single axis system, even two main shaft, but the major diameter cutterhead can not be installed.Under the certain condition of spindle motor power, can only improve moment of torsion like this, the power of motor and moment of torsion not performed to the limit in the middle of invisible by simple speed ratio design.The existing mechanism that forges a knife has only hydraulic pressure to forge a knife and pneumatic forging a knife, and the former causes hydraulic fluid leak easily, and latter's noise is big.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of twin shaft times power the electronic formula axis system of forging a knife at above-mentioned prior art present situation, native system can be installed big cutterhead and finish the major diameter milling, again little cutterhead can be installed and carry out the small size milling and boring cutter is installed is carried out boring processing, and main-shaft torque is multiplied by native system, the more succinct practicality of broaching tool pine cutter.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the electronic formula axis system of forging a knife of this twin shaft times power, include motor and standard main shaft, be in transmission connection by transmission mechanism between main shaft and the motor, it is characterized in that it also includes the large end face main shaft, force multiplication system and electronic tool striking device, wherein the large end face main shaft is installed in the casing of force multiplication system, connect by bearing is nested with the force multiplication system casing, described standard main shaft is installed in the large end face main shaft, the fixed gear and the free gear that are used for driving standard main shaft and the rotation of large end face main shaft respectively are housed on the standard main shaft, fixed gear and free gear are by the transmission that is meshed with gear in the transmission mechanism, described electronic tool striking device comprises that one can drive the screw rod of standard main shaft moving linearly, this screw rod and standard main shaft concentric are provided with, and adopt being in transmission connection of screw pair structure between screw rod and the transmission mechanism.
Described force multiplication system can be according to the big main shaft needs of exerting oneself of holding into, constitute by several power transmission shafts that are installed in the force multiplication system casing, a gear is equipped with at two of power transmission shaft respectively, respectively with the standard main shaft on free gear and the internal gear on the large end face main shaft be meshed.
Described transmission mechanism can adopt mechanical step speed change mechanism or electric stepless speed change mechanism or machinery and the electric gear that combines.
Compared with prior art, advantage of the present utility model is:
1, solves the standard main shaft and can only adorn the problem that little cutterhead carries out the low poor rigidity of efficient of small size cutting, use the large end face main shaft that big cutterhead is installed, can a milling large tracts of land workpiece, improved operating efficiency greatly, and adopt the nesting type structure design, guaranteed enough rigidity;
2, force multiplication system can significantly improve the moment of torsion of large end face main shaft, so output torque is irrelevant with the original peak torque of motor, as long as the power transmission shaft quantity of force multiplication system is directly proportional;
3, the electronic mechanism that forges a knife, no hydraulic pressure the forge a knife hydraulic oil pollution and the pneumatic noise filth of forging a knife of mechanism.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model twin shaft times power is electronic, and the formula axis system of forging a knife mainly is made of motor 13, the assemblings such as transmission mechanism, standard main shaft 1, large end face main shaft 2, force multiplication system and electronic tool striking device that driven by motor 13, wherein be in transmission connection by transmission mechanism between standard main shaft 1 and the motor 13, this transmission mechanism can adopt mechanical step speed change mechanism, also can adopt and do electric stepless speed change mechanism, or machinery and the electric gear that combines.Large end face main shaft 2 is installed in the casing 3 of force multiplication system, connects by bearing is nested with force multiplication system casing 3, to guarantee the rigidity of large end face main shaft 2.Standard main shaft 1 is installed in the large end face main shaft 2, on standard main shaft 1, be equipped with and be used for driving fixed gear 9 and the free gear 8 that standard main shaft 1 and large end face main shaft 2 rotate respectively, and fixed gear 9 and free gear 8 can be meshed with the duplex shifting slide gear 17 in the transmission mechanism.Force multiplication system is used for significantly improving the output torque of large end face main shaft 2, it can be according to the needs of large end face main shaft output torque size, constitute by some power transmission shafts 6, one gear 7,5 all is housed at two of each power transmission shaft 6, respectively with the standard main shaft on free gear 8 and the internal gear 4 on the large end face main shaft be meshed.Electronic tool striking device comprises that one can drive the screw rod 11 of standard main shaft 1 moving linearly, this screw rod 11 and the 1 concentric setting of standard main shaft, and adopt being in transmission connection of screw pair structure between screw rod 11 and the transmission mechanism.
The course of work of the electronic formula axis system of forging a knife of this twin shaft times power is as follows: the output shaft of motor and gear 12 connect by flat key, and driven gear 14 rotates, by the transmission of a series of change-speed gearing pairs, when the double crosslinking sliding gear 17 on the power transmission shaft meshed with gear 16, driven gear 16 rotated.Because of gear 16 is fixed on the gear shaft 15, so 10 rotations of gear shaft 15 driven gears, gear 10 the insides are screw pair, and rotatablely moving of gear 10 become the rectilinear motion of screw rod 11, thereby realize forging a knife motion.In like manner, if the motor counter-rotating then realizes loose cutter motion.
When fixed gear 9 engagements on double crosslinking sliding gear 17 and the standard main shaft, gear 9 and standard main shaft 1 connect by flat key, and like this, the standard main shaft directly rotates.
When free gear 8 engagements on double crosslinking sliding gear 17 and the main shaft, driven gear 7, gear 7 is connected on the power transmission shaft 6 with gear 5 usefulness flat keys, gear 5 and with internal gear 4 engagements, rotate thereby drive large end face main shaft 2.
