Abstract
The utility model discloses a transmission mechanism of a milling power head of a numerical control machine tool; the technical scheme is as follows: the transmission mechanism of the milling power head comprises a main shaft, a motor, a pair of synchronous wheels respectively arranged on the main shaft and a motor rotary shaft, and synchronous belts wound on the synchronous wheels; a power head shell is supported on the main shaft through a front end rolling bearing and a rear end rolling bearing; and the motor is an alternating current servo motor. According to the transmission mechanism of the milling power head, the servo motor is used for replacing the variable frequency motor of the prior art, so the output torque is constant, and a high torque is ensured even under a situation that the rotating speed of the main shaft is quite low, which guarantees smooth tapping of the power head and reflects technological progress.
Description
Technical field
The utility model relates to the numerical control machine tool technique field, particularly relates to a kind of relevant technology of milling unit head transmission of Digit Control Machine Tool.
Background technology
The unit head of using in the numerically controlled lathe of prior art all is to adopt variable-frequency motor to drive, although energy-conservation, the moment of torsion of main shaft is to change along with the variation of speed, and in slow-revving situation, moment of torsion is very little, and the unit head bearing capacity is low, and cutting force is little.Particularly on part in the tapping, because at this moment rotating speed is low, and moment of torsion is little, and threading drill bit is attacked to enter.If this unit head is installed on the common main shaft, high at rotating speed, in the large situation of cutting force, because of reasons such as bearing heating, main shaft poor rigidity, spindle vibration can appear, part has the phenomenons such as chatter mark, causes machining accuracy greatly to descend, and does not reach designing requirement.
This type of unit head can only be used on the process equipment of the low cutting force such as grinding machine, drilling machine, and production efficiency is low.So, can not satisfy the machining production requirement of high speed, precision, those skilled in the art are necessary to improve the milling unit head transmission mechanism of this Digit Control Machine Tool.
Summary of the invention
For the defective of prior art, the technical problem that the utility model solves is: provide a kind of main-shaft torque constant milling unit head transmission mechanism.
The technical scheme that the utility model solves the problems of the technologies described above is: the milling unit head transmission mechanism, comprise main shaft, and motor is installed in respectively a pair of synchronizing wheel on described main shaft and the machine shaft, and is around in the Timing Belt on the described synchronizing wheel; The unit head housing by the front and back ends roller bearings on described main shaft; It is characterized in that described motor selects AC servo motor.
Technique effect of the present utility model is: compared to existing technology, the utility model motor adopts servomotor, and output torque is constant, even if in the very low situation of the speed of mainshaft, still have very large moment of torsion, guarantees the smooth tapping of unit head.
Preferred technical scheme: described Timing Belt is a kind of internal tooth Timing Belt.
Further technique effect: guarantee the constant of output torque.
Preferred technical scheme: described front and back ends rolling bearing relies on axle convex platform, shaft block ring, end cap to be fixed on the described main shaft.
Further technique effect: the axiality that guarantees main shaft
Preferred technical scheme: mechanism's integral arrangement is among casing.
Further technique effect: be conducive to the dustproof and security consideration of transmission mechanism.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated, further illustrate advantage of the present utility model and with respect to the contribution of prior art, understandable, following embodiment only is the detailed description to the better embodiment of the utility model, should not be construed as any restriction to technical solutions of the utility model.
Fig. 1 is the axial cutaway view of the utility model, holding screw fixedly synchronizing wheel 3b on the rotating shaft of AC servo motor 2; Another synchronizing wheel 3a is screwed in main shaft 1 rearward end, and internal tooth Timing Belt 3c is around between synchronizing wheel 3a, the 3b.Main shaft 1 leading section be connected collet 6 and outer-hexagonal clevis head nut 61, front end rolling bearing 41, the rear end rolling bearing 42 of dually arrayed utilize axle to top bar, shaft block ring, end cap is fixed on main shaft 1 front and back end, be furnished with spacer ring between the double-row bearing, unit head housing 4 front and back end disposed axle bearings are supported on the main shaft 1 it.
As shown in Figure 2, adjustment block 7 is used for adjusting the rate of tension of Timing Belt.Above mechanism integral arrangement is conducive to dustproof and safety among casing 5.
By above design, because the output torque of AC servo motor 2 is constant, drive main shaft 1 by it, even if in the very low situation of rotating speed, still can keep moment of torsion, smoothly tapping, cutter head cutting force is large, guarantees part processing precision, has improved productivity ratio, solve the variable-frequency motor defective that output torque also reduces simultaneously when rotating speed reduces in the prior art, embodied technological progress.
