Abstract
The utility model discloses a digitalized precise dividing mechanism for a large horizontal machine tool, comprising a main drive reduction device, a main axle, an auxiliary axle for transferring the drive to the auxiliary axle of the main axle after the main drive reduction device reduces and also comprising a high precision rotary coder, a digitalized direct-current speed-adjustment electric machine, a division reduction device and a clutch, wherein the clutch, the digitalized direct-current speed-adjustment electric machine and the division reduction device are coaxially mounted on the main drive reduction device to adjust the speed of the main drive reduction device and the high precision rotary coder is mounted at the tail part of the main axle to send the rotary speed signal of the machine tool to a PLC and the digitalized direct-current speed-adjustment electric machine is controlled by the PLC. The division adjustment is realized by correcting the parameter value of the program in the main control device and time for exchanging a hanging wheel in the prior division adjustment process is saved, the division efficiency is increased; because the digitalized precise dividing mechanism can accurately make the face plate rotate at the preset position, the auxiliary positioning is not needed and then a locking device is not needed and the dividing mechanism is simplified.
Description
Technical field
The utility model relates to a kind of digitlization indexing mechanism, particularly a kind of digital accurate indexing mechanism that is used for the large-size horizontal lathe.
Background technology
Existing face lathe, what majority adopted is that mechanical dividing mechanism realizes calibration.This mechanical dividing mechanism mainly comprises change gear, a series of reduction gearing, worm and gear and locking device.Change gear is at first passed through in the transmission output of common electric machine or main motor, is delivered to worm-and-wheel gear through a series of reduction gearing again, and last worm gear drives floral disc rotates.Adopt this mechanical dividing mechanism, floral disc generally all can not forward the precalculated position to exactly, will carry out assist location with locking device to floral disc again so floral disc rotates after finishing.In the time will realizing different calibration, need change different change gears.
The shortcoming of this mechanical dividing mechanism is: one, structure is comparatively complicated, and the trouble point increases; Two, the calibration of realizing different stage need be changed different change gears, and this just requires to change change gear in addition at every turn and approximately will spend 15 to 20 minutes into this lathe is equipped with a huge change gear storehouse, and calibration efficient is not high.
The utility model content
The digital accurate indexing mechanism that is used for the large-size horizontal lathe that provides a kind of indexing accuracy and calibration efficient all very high is provided the purpose of this utility model.
This digital accurate indexing mechanism that is used for the large-size horizontal lathe that the utility model provides, comprise the main transmission reductor, main shaft, be used for the transmission of power after the deceleration of main transmission reductor is given the countershaft of main shaft, also comprise the high accuracy rotary encoder, the digitlization dc speed-regulating motor, calibration reductor and clutch, described clutch, the digitlization dc speed-regulating motor, coaxial being installed in of calibration reductor is used to regulate main transmission reductor speed on the main transmission reductor, the high accuracy rotary encoder is installed in the main shaft afterbody, be used for lathe master's tach signal is sent to PLC, by PLC control figure dc speed-regulating motor.
The utility model compared with prior art has following characteristics:
1, calibration is only regulated and just can be realized by the parameter values of revising program in the master control set, has saved the time that original calibration is regulated the replacing change gear of being spent, and has improved calibration efficient;
2, because the digitlization dc speed-regulating motor can stepless speed regulation, the indexing accuracy of indexing mechanism is greatly improved; Can cancel the change gear and the part indexing and driving mechanism that were used to realize speed governing originally then, motor is directly connected to graduation transmission device, has simplified indexing mechanism;
3, directly drive floral disc and rotate, canceled worm and gear, simplified indexing mechanism with speed reduction gearing;
4, because this digitlization speed adjusting gear can make floral disc forward the precalculated position to exactly, no longer need assist location, thereby canceled locking device, further simplified indexing mechanism.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As can be seen from Figure 1, this digital accurate indexing mechanism that is used for the large-size horizontal lathe of the utility model, comprise main transmission reductor 1, shaft coupling 2, countershaft 3, main shaft 4, gear 5, floral disc 6, high accuracy rotary encoder 7, digitlization dc speed-regulating motor 8, calibration reductor 9 and clutch 10, main transmission reductor 1 links to each other with countershaft 3 by shaft coupling 2, countershaft 3 links to each other with floral disc 6 by gear 5, floral disc 6 is fixedly connected on main shaft 4 heads, described digitlization dc speed-regulating motor 8, calibration reductor 9, clutch 10 coaxial being installed on the main transmission reductor 1, wherein digitlization dc speed-regulating motor 8 links to each other with calibration reductor 9, calibration reductor 9 links to each other with main transmission reductor 1 by clutch 10, can be used for regulating main transmission reductor speed, high accuracy rotary encoder 7 is installed in main shaft 4 afterbodys, be used for lathe master's tach signal is sent to PLC, by PLC control figure dc speed-regulating motor 8.
