Abstract
The invention relates to an operating platform structure for a vertical lathe. The operating platform structure comprises a base, a platform surface, a cover plate and a spindle, wherein the spindle is fastened on the base through a sixth bolt; the operating platform structure is characterized by further comprising a gear ring, a tapered sleeve, an upper pressing plate 17 and a lower pressing plate; the gear ring is fixed on the platform surface through a first bolt; the spindle is fastened on the base through the sixth bolt; the lower pressing plate is fixed on the tapered sleeve through a fifth bolt; a double-line cylinder roller bearing is mounted on the spindle through a third adjusting pad and supports the tapered sleeve; the upper pressing plate is tightly pressed on the cylinder roller bearing through a locking nut; a second plane bearing is mounted on the tapered sleeve and is adjusted by using a second adjusting pad; the cover plate is tightly pressed on the double-line cylinder roller bearing through a fourth bolt; a first plane bearing is mounted on the base; and a first adjusting pad is mounted on the spindle and is used for adjusting a gap between the first plane bearing and the platform surface. The operating platform structure has the advantages of high platform surface bearing capacity, no maintenance, less energy consumption, high rotation precision of the platform surface and capability of ensuring the processing precision demand.
Description
Technical field
The present invention relates to a kind of vertical lathe workstation structure, 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 table top and base mutually to slide by the guide rail plate, the middle structure that supports by oil film, but in this structure, two guide pass adopt oil film to support, and the gap is larger, there is rubbish to enter guide pass, cause the guide pass plucking, quality of fit descends, in addition, because adopting oil film, supports rotary course, under the factor affecting such as the oil circuit pressure loss and leakage, the oil film abutment pressure is unstable, also can cause machining accuracy to reduce.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of vertical lathe workbench structure simple and reasonable for structure is provided, this structure table top bearing capacity is large, need not safeguard, energy consumption is little, and the table top rotating accuracy is high, can guarantee requirement on machining accuracy.
According to technical scheme provided by the invention: a kind of vertical lathe workbench structure comprises base, table top, cover plate, main shaft, main shaft by the 6th bolted on base; Feature is: also comprise gear ring, taper sheath, top board, lower platen; Described gear ring is bolted on the table top by first, lower platen is bolted on the tapered sleeve by the 5th, Biserial cylindrical roller bearing is installed on the main shaft by the 3rd adjusting pad, support taper sheath, top board is pressed on the cylinder roller bearing by locking nut, the second plane bearing is installed on the taper sheath, with the second adjusting pad adjustment, with the 4th bolt cover plate is pressed on the bearing.The first plane bearing is installed on the base, and the first adjusting pad is installed on the main shaft, is used for adjusting gap between the first plane bearing and table top.
As a further improvement on the present invention, adopt the first plane bearing to support between described table top and base.As a further improvement on the present invention, described table top is bolted on the taper sheath with second.
As a further improvement on the present invention, the second adjusting pad is housed between described main shaft and cover 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, need not safeguard, energy consumption is little, and the table top rotating accuracy is high, has guaranteed requirement on machining accuracy; Can effectively solve the not enough problem that exists in original technology.
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 described in Figure 1, a kind of vertical lathe workbench structure comprises base 1, table top 2, gear ring 3, the first bolt 4, the first plane bearing 5, the first adjusting pad 6, the second bolt 7, taper sheath 8, the 3rd bolt 9, the second plane bearing 10, end cap 11, locking nut 12, cover plate 13, main shaft 14, the 4th bolt 15, the second adjusting pad 16, top board 17, Biserial cylindrical roller bearing 18, the 3rd adjusting pad 19, lower platen 20, the 5th bolt 21 and the 6th bolt 22.
The present invention adopts plane bearing supporting bable tops structure, has changed the structure that original oil film supports, and has so just guaranteed the stationarity that table top rotatablely moves, thereby has guaranteed requirement on machining accuracy.
