Abstract
The invention relates to a working table structure for a short spindle of a vertical lathe. The working table structure comprises a base, a table surface and a spindle, wherein the spindle is fixed on the base, two rows of cylindrical roller bearings are installed on the spindle, a lower pressing plate is fixed on the working table surface, a first plane bearing is installed on the base, a press ring is installed on the spindle, a gear ring is installed on the table surface, a second plane bearing is installed in a bearing hole on the table surface, the working table surface is installed on the spindle, the upper end of the spindle is adjusted through a first adjusting pad, and a cover plate is fixed on the working table surface through a third bolt. The table surface is supported by the first plane bearing, the bearing capacity of the table surface is large, friction of the working table surface is pure rolling friction, the energy consumption is small, the rotary precision of the table surface is high, jumping error of end surfaces of workpieces is small during processing, and the requirements for processing accuracy can be met.
Description
Technical field
The present invention relates to the short spindle table structure of a kind of vertical lathe, belong to the machinery industry technical field.
Background technology
In the vertical lathe process, the rotatablely moving of workbench, the tool feeding motion reaches smear metal processing.The stationarity of worktable rotary motion has a significant impact the workpiece crudy, rotates not steadily, and table top is beated greatly, and machining accuracy is low.At present, general vertical lathe workbench structure adopts workbench dynamic and static pressure guide rail structure, the middle structure that supports by oil film, but in this structure, two guide pass adopt oil film to support, and rubbish enters guide pass easily, cause the guide pass plucking, quality of fit descends, and in addition, supports because rotary course adopts oil film, under the factor affecting such as the oil circuit pressure loss and leakage, the oil film abutment pressure is unstable, causes processing work end face run-out error to increase, and machining accuracy reduces.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of short spindle table structure simple and reasonable for structure is provided, this structure can effectively solve the not enough problem that exists in original technology.
According to technical scheme provided by the invention: the short spindle table structure of a kind of vertical lathe comprises base, table top, lower platen, pressure ring, main shaft, pressing plate, cover plate and gear ring; Described main shaft is bolted on the base by first, and Biserial cylindrical roller bearing is installed on the main shaft, and described lower platen is fixed on the work top, and the first plane bearing is installed on the base, adopts the first plane bearing to support between described table top and base; Described pressure ring is installed on the main shaft, compress the double-row roller bearing inner ring, the above locks with locking nut, described gear ring is installed on the table top by the 4th bolt, the second plane bearing is installed in the dead eye on the table top, and work top is installed on the main shaft, with the second bolt pressing plate, the first adjusting pad is installed in the main shaft upper end, the main shaft upper end is by the adjustment of the first adjusting pad, and described cover plate is bolted on the work top by the 3rd.
As a further improvement on the present invention, the second adjusting pad is installed between described main shaft and double-row roller bearing.Described table top supports by the second plane bearing, compresses with pressing plate.
The present invention compared with prior art, advantage is: the present invention adopts the first plane bearing supporting bable tops, and the table top bearing capacity is large, Working table structure is pure rolling friction, and energy consumption is little, and the table top rotating accuracy is high, make that the workpiece end face runout error reduces in the process, guaranteed requirement on machining accuracy.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1: the short spindle table structure of a kind of vertical lathe comprises base 1, table top 2, the first plane bearing 3, the first bolt 4, lower platen 5, Biserial cylindrical roller bearing 6, pressure ring 7, the second plane bearing 8, main shaft 9, the first adjusting pad 10, pressing plate 11, the second bolt 12, locking nut 13, cover plate 14, the 3rd bolt 15, the second adjusting pad 16, the 4th bolt 17 and gear ring 18 etc.
Described main shaft 9 is fixed on the base 1 by the first bolt 4, Biserial cylindrical roller bearing 6 is installed on the main shaft 9, at main shaft 9 and 6 of double-row roller bearings the second adjusting pad 16 is installed, described lower platen 5 is fixed on the work top 2, the first plane bearing 3 is installed on the base 1, and 1 of described table top 2 and base adopt the first plane bearing 3 to support.Described pressure ring 7 is installed on the main shaft 9, compress double-row roller bearing 6 inner rings, the above locks with locking nut 13, described gear ring 18 is installed on the table top 2 by the 4th bolt 17, the second plane bearing 8 is installed in the dead eye on the table top 2, and work top 2 is installed on the main shaft 9, and the upper end is by the adjustment of the first adjusting pad 10, with the second bolt 12 pressing plate 11 is pressed solidly and to fix on the main shaft 9, described cover plate 14 is fixed on the work top 2 by the 3rd bolt 15.
The present invention adopts plane bearing supporting bable tops structure, becomes former dynamic and static pressure guide rail mode and is the mode of pure rolling friction, and the table top rotating accuracy is high, thereby has guaranteed requirement on machining accuracy.
