The high-pressure oil passage that installation plate is braked.
The improvement of technical solution of the present invention is further used as, is fixed in the upper end that cycloid reducer engages with panoramic table
An elastic panel is connected with, screwed hole is provided with elastic panel, panoramic table is provided through on panoramic table and is threadedly connected to institute
State the trip bolt on screwed hole.
The improvement of technical solution of the present invention is further used as, positioned at closed between the composition surface of annular flange and pressure ring part
Oil pocket both sides are provided with some sealing rings.
The beneficial effects of the invention are as follows：A kind of this machining tool is by the use of rotary table directly using cycloid reducer as subtracting
Fast mechanism, because input shaft and the output shaft of cycloid reducer be on same axis and small volume so that overall a kind of to add
The structure design of work lathe rotary table is more compact, greatly reduce a kind of volume of machining tool rotary table and
Weight, while abandoning tradition uses gear or turbine and worm decelerator, reduces drive gap therein, a kind of processing of raising
The operating accuracy of lathe rotary table.
Brief description of the drawings
The present invention is described further with reference to the accompanying drawings and examples；
Fig. 1 is the sectional view of the embodiment of the present invention；
Fig. 2 is the positive structure schematic of the embodiment of the present invention；
Fig. 3 is the structure schematic diagram of the embodiment of the present invention.
Embodiment
Referring to figs. 1 to Fig. 3, a kind of machining tool rotary table of the present invention, including plate 10 is installed, located at installing plate
The motor 20 of the lower section of part 10, and the cycloid reducer being connected located at the middle part of installation plate 10 with motor 20
30, the output end of cycloid reducer 30, which is fixedly connected, panoramic table 40.
A kind of this machining tool by the use of rotary table directly using cycloid reducer 30 as reducing gear, due to Cycloidal Wheel
The input shaft of decelerator 30 is in output shaft on same axis and small volume so that a kind of revolution work of overall machining tool
The structure design of platform is more compact, greatly reduces a kind of volume and weight of machining tool rotary table, and Cycloidal Wheel
The gearratio of decelerator 30 can make greatly panoramic table obtain bigger moment of torsion, while abandoning tradition uses gear or worm-gear speed reducer
Structure, reduce drive gap therein, a kind of operating accuracy of machining tool rotary table of raising.
As the preferred embodiment of the present invention, the lower surface of panoramic table 40 is in contact with installation plate 10 upper surface, is returning
Annular oil cavity 41 is provided with to form lubricating oil film between the composition surface of the lower surface of turntable 40 and installation plate 10 upper surface.
Installation plate 10 is a rectangular slab, and chute is provided with its lower surface so that installation plate 10 can be slipped in lathe
Upper horizontal slip, the middle part of installation plate 10 are provided with installation circular hole, and cycloid reducer 30 is fixedly mounted on installing plate by screw
On part, the input of cycloid reducer 30 couples with the output end of motor 20, and the output end of cycloid reducer 30
Directly it is fixedly connected at the center of panoramic table 40, panoramic table 40 is in a dish type, the lower surface of panoramic table 40 and installation plate 10 upper surface
Contact, that is, the upper surface for installing plate 10 is mainly used in carrying the weight of whole panoramic table 40, by panoramic table 40 and installation
Lubricating oil film is provided between the composition surface of plate 10, lubricating oil film is used to carry panoramic table 40 and reduces panoramic table 40 and installing plate
Frictional resistance between part 10.
As the preferred embodiment of the present invention, the outer lower end of panoramic table 40 has radially extended an annular flange 42 outward,
The pressure ring part 43 of the fastening annular flange 42 is fixed with installation plate 10, in the upper surface of annular flange 42 and pressure ring part
Closed oil pocket 44 is provided between the composition surface of 43 lower surfaces, be provided with the pressure ring part 43 can be passed through to closed oil pocket 44 hydraulic oil with
