Abstract
The invention relates to a high-precision rotator which comprises an apex, a pedestal, a main shaft, a shaft sleeve, a socket sleeve, a motor and a motor socket sleeve, wherein the apex is connected with the main shaft through the pedestal; the main shaft is fixed with the socket sleeve through the shaft sleeve; and the motor is fixed in the motor socket sleeve and directly connected to the main shaft. The direct connection of the motor and the main shaft replaces the connection by using a coupling in the traditional method, thereby realizing the precise synchronization of the motor and the main shaft, and also realizing the high-speed high-precision transmission; and the invention adopts a full fixed main shaft and most of the main shaft is connected with the socket sleeve through the shaft sleeve, thus the stability and transmission precision of the motor can be well ensured at the start and stop moments.
Description
Technical field
The present invention relates to a kind of high-precision rotary device.
Background technique
The swivel gear of prior art generally adopts bearings at both ends to fix, and axle head and motor adopt coupling to be connected, and stationarity is relatively poor in the motor rotation process, quickens suddenly, impact and amplitude are bigger when stopping; And bearings at both ends fixes, and adds the requirement of part and assembly technology for machine and requires all very highly, cannot say for sure card; Motor is connected by coupling with main shaft, and the coaxality of two spindle axis requires manufacturability very high, cannot say for sure to demonstrate,prove; The most important thing is that transmission accuracy is not high.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of convenient, fast, high-precision high-precision rotary device.The present invention is achieved through the following technical solutions:
A kind of high-precision rotary device of the present invention comprises top, pedestal, main shaft, axle sleeve, cover for seat, motor and motor cover for seat; Wherein, described toply connect together by pedestal and main shaft, main shaft is fixed together by axle sleeve and cover for seat; Motor is fixed in the motor cover for seat, and motor directly connects main shaft.
As preferably, described main shaft tail end is provided with rotator seat.
As preferably, be provided with the stator seat of fixed electrical machinery below the described motor cover for seat.
A kind of high-precision rotary device of the present invention adopts motor and main shaft directly to connect and has replaced the conventional method that connects with coupling, can realize that motor and main shaft are synchronous, and perfectness can accomplish that high rotating speed highi degree of accuracy transmits; Secondly the present invention adopts full fixed main shaft method, with axle sleeve most of and cover for seat linking at main shaft
Together, no matter motor can both well guarantee its stability and transmission accuracy in the moment that starts and stop.
Description of drawings
In order to be easy to explanation, the present invention is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the three-dimensional combination figure of high-precision rotary device of the present invention;
Fig. 2 is the sectional view of high-precision rotary device of the present invention.
Embodiment
A kind of high-precision rotary device of the present invention, as depicted in figs. 1 and 2, comprise top 1, pedestal 2, main shaft 3, axle sleeve 4, cover for seat 5, stator seat 6, rotator seat 7, motor cover for seat 8 and motor 9, top 1 connects together by pedestal 2 and main shaft 3, and main shaft 3 is fixed together by axle sleeve 4 and cover for seat 5; Axle sleeve 4 guarantees stability and the flexibility that main shaft 3 rotates; Rotator seat 7 is used for fixing main shaft 3 tail ends, and motor cover for seat 8 and stator seat 6 are used for fixing motor 9, and motor 9 is fixed on the motor cover for seat 8 by stator seat 6, and by motor 9 direct drive main spindle 3, main shaft 3 drives top 1 running.
The present invention adopts motor and main shaft directly to connect to have replaced the conventional method that connects with coupling, can realize that motor and main shaft are synchronous, and perfectness can be accomplished high rotating speed highi degree of accuracy transmission; Complete secondly the present invention adopts the fixed main shaft method, be engaged togather in main shaft major part and cover for seat with axle sleeve, no matter motor can both well guarantee its stability and transmission accuracy in the moment that starts and stop.
The foregoing description, just example of the present invention is not to be used for limiting interest field of the present invention, and is all according to equivalence variation and modification that the present invention did, all should be included in the patent claimed range of the present invention.
