A stator of the torque motor is mounted on the box body, a rotator of the torque motor is mounted on the precision spindle, a rotating encoder or an angle encoder are arranged on the precision spindle, and an axial fixing positioning element is arranged at the front end of the precision spindle. According to the indexable insert peripheral grinding machine transmission device, the stator of the torque motor is mounted on the box body, the rotor of the torque motor is mounted on the precision spindle, a transmission part is not needed in the driving process, therefore, transmission errors are eliminated, the rotating precision of an indexable insert peripheral grinding machine is greatly improved, the indexable insert machining precision of the indexable insert peripheral grinding machine is correspondingly improved, and the dimensional consistency and the precision stability of indexable inserts are effectively guaranteed.
Description
Technical field
The utility model relates to a kind of transmission device, particularly relates to a kind of transmission device of indexable insert tip periphery grinding machine.
Background technology
In modern high precision numerical control periphery grinding machine, the transmission device of processing indexable insert tip, throw away tip is the critical component that guarantees the indexable insert tip, throw away tip machining accuracy.The transmission of indexable insert tip, throw away tip refers to the gyration of indexable insert tip, throw away tip around the fixture central axis.In the prior art, when general indexable insert tip periphery grinding machine carries out the peripheral grinding transposition to indexable insert tip, throw away tip, normally adopt the worm-and-wheel gear transmission.Due to structural limitations, worm gear generally can not be too large; In order further to reduce rotating speed, usually in previous stage, increase gear pair.Unavoidably there is driving error in this kind of drive, and the way that prior art solves problems mainly contains two kinds of approach:
One: machinery is eliminated gap.As adopted, clearance elimination gear is secondary, the anti-backlash worm wheel worm gear pair; The clearance elimination gear pair arranges pinion and gear wheel, and gear wheel is split gear, for the gap that disappears; What the anti-backlash worm wheel worm gear pair arranged worm screw is the double-joint type structure, but generally can only limited minimizing gap and error.
Its two: gap is eliminated in compensation.Same kind of products at abroad general using modern electronic technology compensates the gap that disappears, CAP sensor for example, although the CAP sensor also can complete other function when detecting drive gap, but, because does not really eliminate in gap, the Accuracy to workpiece in process still exists.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of high-precision edge bed of the indexable insert tip, throw away tip for indexable insert tip, throw away tip edge bed transmission device.
The technical solution adopted in the utility model is: comprise casing, torque motor and accurate main shaft, the stator of described torque motor is arranged on casing, the rotor of torque motor is arranged on accurate main shaft, accurate main shaft is provided with rotary encoder or angular encoder, and the front end of described accurate main shaft is provided with the axial restraint setting element.
In above-mentioned indexable insert tip, throw away tip edge bed transmission device, the installation place corresponding to torque motor on described casing is provided with fin.
In above-mentioned indexable insert tip, throw away tip edge bed transmission device, described accurate main shaft is bearing in casing by fore bearing and rear bearing.
Compared with prior art, the beneficial effects of the utility model are: the stator of torque motor of the present utility model is arranged on casing, the rotor of torque motor is arranged on accurate main shaft, there is no drive disk assembly in the driving process, therefore eliminated driving error, greatly improve the rotating accuracy of indexable insert tip periphery grinding machine, improved accordingly the machining accuracy of indexable insert tip periphery grinding machine processing indexable insert tip, throw away tip, effectively guaranteed the uniformity of size of indexable insert tip, throw away tip and the stability of precision.
The accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model.
Fig. 2 is profile schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises casing 1, torque motor 3 and accurate main shaft 2, the stator 31 of described torque motor 3 is arranged on casing 1, the rotor 32 of torque motor 3 is arranged on accurate main shaft 2, torque motor 3 on casing 1 directly drives accurate main shaft 2 like this, centre, without any transmission link, can not produce driving error fully, and transmission accuracy is high.Described accurate main shaft 2 is bearing in casing 1 by fore bearing 7 and rear bearing 4, and accurate main shaft 2 is provided with rotary encoder or angular encoder 5, and the front end of accurate main shaft 2 is provided with axial restraint setting element 6.Described fore bearing 7 and rear bearing 4 can be rolling bearings, can be also sliding bearings.The utility model adopts rolling bearing, and fore bearing 7 employing leading screw spring bearings, and the leading screw spring bearing has higher axial carrying capacity.
Described axial restraint setting element 6, can be plane for the end face of locating, and can be also curved surface, for axial location, adds porose and work indexable insert tip, throw away tip atresia.Axial restraint setting element 6 is arranged on the front end of accurate main shaft 2, and under the effect of clamping force, together the axis around accurate main shaft 2 rotates.Usually, axial restraint setting element 6 has or not the situation of centre bore according to indexable insert tip, throw away tip, determines to be solid or hollow-core construction, and when indexable insert tip, throw away tip, during without centre bore, axial restraint setting element 6 is solid construction; When indexable insert tip, throw away tip has centre bore, can be with the centre bore location of indexable insert tip, throw away tip, axial restraint setting element 6 is for becoming hollow-core construction.
During use, when torque motor 3 directly drives the accurate main shaft 2 of zero transmission, torque motor 3 is due to the characteristic of high moment of torsion, large electric current, and easy temperature rise is to higher temperature, and then the driveability of influence power torque motor 3 and precision.Therefore, as shown in Figure 1, 2, the installation place corresponding to torque motor 3 on casing 1 is provided with fin 11 heat radiations.The external forced that cooling fluid while simultaneously, utilizing the blade grinding is carried out large flow to the external refrigeration fin 11 of torque motor 3 is cooling.
