For the terminal use of lathe, the increase meeting of appearance and size directly affects the floor space of lathe in factory building, for the user of lathe, is meeting under the prerequisite of using, and that yes is the smaller the better for floor space.
For existing problem in above-mentioned prior art, research and design is a kind of novel directly drives the power cutter tower of cutterhead with torque motor, thereby overcome existing problem in prior art, is very necessary.
Summary of the invention
In view of existing problem in above-mentioned prior art, the purpose of this utility model is a kind of novel power cutter tower that directly drives cutterhead with torque motor of research and design.In order to solve, in prior art, exist: 1, use the cutter tower body of common servomotor band speed reducer drive long-pending large, take up room; 2, many transmission links of reductor, transmission accuracy is low, and drive gap is large; 3, the problems such as equipment cost and maintenance cost have been increased.
Technical solution of the present utility model is achieved in that
The power cutter tower that directly drives cutterhead with torque motor described in the utility model, by cutterhead, spindle motor, mandrel, guide finger, interior fluted disc, outer tooth disk, side fluted disc, fluted disc seat and cutterhead transmission inner sleeve, formed, be set in the outside of mandrel in the cutterhead transmission, the fluted disc seat is loaded on the front portion of cutterhead transmission inner sleeve, guide finger, side fluted disc, outer tooth disk and interior fluted disc are housed successively on the fluted disc seat, front end and the electric machine main shaft of mandrel are bolted, and cutterhead is connected with interior fluted disc and cutterhead transmission inner sleeve by bolt respectively; It is characterized in that, at the rear portion of cutterhead transmission inner sleeve, power set and rotation angle detection apparatus are housed; Casing is loaded on the power set outside; The mandrel hold-down support is equipped with at the rear portion of mandrel, and fixes by locking nut, and the mandrel hold-down support is bolted on casing simultaneously.
Power set described in the utility model comprise torque motor stator and torque motor rotor; Described torque motor rotor is loaded in the cutterhead rotation and puts by bolt, and the torque motor stator is contained in the outside of torque motor rotor, and is connected with casing by screw.
Rotation angle detection apparatus described in the utility model comprises read head mount pad, encoder read head, gear encoder and coding seat; Described coding seat is loaded on the end of cutterhead transmission inner sleeve by bolt, the gear encoder is loaded on the coding seat; Described read head mount pad is loaded on the torque motor stator by bolt, and the encoder read head is loaded on the read head mount pad.
The course of work of the present utility model is:
At the cutterhead locking state, the left side oil pocket of side fluted disc enters oil, and the side fluted disc be take guide finger and moved to right-hand member as guiding, and now the side fluted disc unclamps, and interior fluted disc and outer tooth disk can relative motions, and cutterhead can rotate.
After the side fluted disc unclamps, torque motor obtains electric, and the torque motor rotor starts to be with the rotation of movable knife disc transmission inner sleeve, the rotation of cutterhead transmission inner sleeve band movable knife disc.Through the gear encoder, detect, after cutterhead is rotated in place, the torque motor outage.
After cutterhead is rotated in place, the oil pocket oil-feed of side fluted disc right side, the side fluted disc be take guide finger and is moved to left end as guiding, by the locking of interior fluted disc and outer tooth disk, makes it can not relative motion, cutterhead locking.
When changing next cutter spacing again, main shaft need stop through a step standard, stops to tool change position, can match with the key of tool rest end, can repeat above tool changing action, starts tool changing.
The utility model has the advantages that apparently, be mainly manifested in:
1, the utility model has been used torque motor to replace original common servomotor to drive the speed reducer drive mode, and the installation length of cutter tower is shortened greatly.For example, rated speed 3000r/min, nominal torque 2Nm, the servomotor acceleration and deceleration machine scheme of speed reducing ratio 1:70, if substitute by the torque motor scheme, with torque motor, directly drive the power cutter tower entire length size of cutterhead can reduce nearly 350mm, total length has reduced approximately 1/3;
2, the utility model has been used torque motor to replace original common servomotor to drive the speed reducer drive mode, has reduced original this transmission link with reductor, has improved the precision on machine driving.
