Abstract

The utility model relates to a kind of digital control vertical internal and external grinding machine work table rotation transmission mechanism, comprise and be arranged on motor on rear side of lathe bed, be placed in reductor, workbench below lathe bed internal work platform, described motor connects the power shaft of reductor by power transmission shaft, speed machine output shaft connects hydrostatic bearing, described hydrostatic bearing is by centration axis adpting flange cover, flange sleeve is installed on the table, thus realizes the rotation of motor drive operational platform.The utility model realizes compared with the structure of table revolving movement with traditional with belt transmission, achieves steady, the big speed ratio of digital control vertical internal and external grinding machine work table rotation, high accuracy transmission; Because reductor and power transmission shaft are installed on bracing frame, make later period maintenance more convenient; Compared with the structure directly driving worktable rotary with torque motor, the cost of this mechanism is lower.

Description

Digital control vertical internal and external grinding machine work table rotation transmission mechanism
Technical field
The utility model relates to a kind of platen slew gear, especially a kind of work table rotation transmission mechanism of digital control vertical internal and external grinding machine.
Background technology
At present, the digital control vertical internal and external grinding machine that domestic manufacturer produces, work table rotation transmission mechanism adopts belt transmission and direct drive of torque motor mostly, above-mentioned Liang Zhong mechanism is as the transmission mechanism of work table rotation, there is its respective shortcoming: belt transmission is applicable to the less lathe of transmission distance, apart from time large, easily there is vibration, affect transmission accuracy in transmission; Though direct drive of torque motor structure is simple but purchase cost is too high, during marketing, there is difficulty.
Summary of the invention
In order to realize the high-precision rotary of the vertical internal and external grinding machine workbench of large-sized numerical control, the utility model provides a kind of digital control vertical internal and external grinding machine work table rotation transmission mechanism, this mechanism is linked together motor and speed reducer by power transmission shaft, motor passes to reductor by power transmission shaft rotary motion, thus driving work table rotation, this mechanism driving steadily ensure that the high-precision rotary of vertical grinder upper table.
To achieve these goals, the technical solution adopted in the utility model is: a kind of digital control vertical internal and external grinding machine work table rotation transmission mechanism, comprise and be arranged on motor on rear side of lathe bed, be placed in reductor, workbench below lathe bed internal work platform, described motor connects the power shaft of reductor by power transmission shaft, speed reducer output shaft connects hydrostatic bearing, described hydrostatic bearing is by centration axis adpting flange cover, and flange sleeve is installed on the table, thus realizes the rotation of motor drive operational platform.
Described power transmission shaft is arranged on power transmission shaft bracing frame, described reductor is arranged on reductor installing plate, reductor installing plate is fixed on bracing frame, and between reductor installing plate and bracing frame, adjusting bracket, cam follower, adjustment screw are housed, wherein, adjusting bracket is equipped with on bracing frame, and cam follower is arranged on adjusting bracket, adjustment screw is threaded with adjusting bracket, for the adjustment of adjusting bracket upper-lower position.
The beneficial effects of the utility model are:
1. well to solve drive motors and work table rotation centre distance comparatively far away in the application of this mechanism, and the problem that gearratio is very large;
2. transmission is more steady compared with belt transmission structure, is more suitable for the revolution transmission of the vertical inside and outside circle workbench of large-sized numerical control;
3., because reductor and power transmission shaft are installed in gripper shoe, during maintenance, dismounting is convenient, time saving and energy saving.
Work table rotation drive mechanism of the present utility model, compared with the common transmission mechanism being used in vertical internal and external grinding machine work table rotation, stable drive, transmission accuracy are high and can realize big speed ratio transmission, and compared with the structure directly driving worktable rotary with torque motor, cost is lower.
