Abstract
The utility model relates to a short main shaft worktable structure of a vertical lathe. The short main shaft worktable structure of the vertical lathe comprises a base seat, a tabletop and a main shaft, wherein the main shaft is fixed on the base seat, double rows of cylindrical roller bearings are installed on the main shaft, a lower pressing plate is fixed on the tabletop, a first plane bearing is installed on the base seat, a pressing ring is arranged on the main shaft, a gear is arranged on the tabletop, a second plane bearing is installed in a bearing hole of the tabletop, the tabletop is installed on the main shaft, the upper end of the main shaft is adjusted through a first adjustment pad, and a covering plate is fixed on the tabletop through a third bolt. According to the short main shaft worktable structure of the vertical lathe, the first plane bearing is used for supporting the tabletop, the bearing capacity of the tabletop is large, the worktable is in a fully rolling friction structure, the energy consumption is small, the rotation accuracy of the tabletop is high, the jumping error of the end surface of a workpiece is reduced in the machining process, and the requirement for machining accuracy is guaranteed.
Description
Technical field
The utility model relates to the short spindle table structure of a kind of vertical lathe, belongs 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 purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of short spindle table structure simple and reasonable for structure is provided, and this structure can effectively solve the not enough problem that exists in original technology.
The technical scheme that provides according to the utility model: 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 further improvement of the utility model, 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 utility model compared with prior art, advantage is: the utility model adopts the first plane bearing supporting bable tops, the table top bearing capacity is large, Working table structure is pure rolling friction, energy consumption is little, the table top rotating accuracy is high, makes that the workpiece end face runout error reduces in the process, has guaranteed requirement on machining accuracy.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail 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 utility model 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.
