Abstract
The present invention relates to a kind of locking protecting device for platform-type single shaft air-float turntable, which is made of locking bracket, tie down screw, locking bed, microswitch seat, microswitch and locking adjustment plate.The locking device can prevent turntable from starting the damage for causing air floating shaft system in the case where being not powered on and ventilating turntable in platform-type single shaft air-float turntable when not in use by its table top and air floating shaft system locking.Simultaneously be also avoided that air floating shaft system be displaced during transportation friction and caused by damage.
Description
Technical field:
The present invention relates to a kind of locking protecting devices for platform-type single shaft air-float turntable, are the spies according to air floating shaft system
Point, a kind of collection specially designed is mechanical, electrical integrated locking, protective device.
Background technique:
Platform-type single shaft air-float turntable is a kind of high-precision electronic single axle table, and rotating accuracy is up to 0.6 ", position
Precision can reach peak-to-peak value 1 " (peak-to-peak value).The core component of platform-type single shaft air-float turntable is a set of air-bearing, air-bearing shafts
The precision held directly determines the mechanical precision of turntable.And there is one layer of air film to be situated between air-bearing rotor and stator as rolling
Matter, therefore the rotor of air-bearing and stator in relative motion and are not directly contacted with.Also just because of when air-bearing works simultaneously
There is no mechanical friction, rotating accuracy can reach 0.6 ", and high-speed rotation can be done.Rotor and stator when due to air-bearing work
Between using gas as rolling medium, therefore air-bearing provides in the non-steady operation of its air supply system and for it stable air film
When, bearing can be caused to damage if having relative motion between air-bearing rotor and stator, influence its precision.Therefore it designs
This locking protecting device purpose, which is that, prevents turntable rotating table in the case where being not powered on and ventilating, and causes air-bearing
Damage.Simultaneously be also avoided that air floating shaft system be displaced during transportation friction and caused by damage.
Summary of the invention:
This locking protecting device purpose, which is that, prevents turntable rotating table in the case where being not powered on and ventilating, and causes gas
The damage that floating axle is held.Simultaneously be also avoided that air floating shaft system be displaced during transportation friction and caused by damage.
The object of the present invention is achieved like this:
A kind of locking protecting device for platform-type single shaft air-float turntable, including locking bracket, tie down screw, locking
Seat, microswitch seat, microswitch and locking adjustment plate.The locking bracket of locking protecting device is connected to platform-type single shaft air bearing
On the Table top able to be rotated of turntable, locking adjustment plate be then connected on the pedestal of platform-type single shaft air-float turntable, the device use when at
To using, at 180 ° of uniformly distributed installations.Terminate in turntable in use, tie down screw is screwed into locking bed along locking bracket, when tightening
Mechanical interlocking can be carried out to air floating shaft system when tie down screw, and since the locking protecting device is at 180 ° of mounted in pairs, both sides
It only is applied with axial force to air-bearing when locking simultaneously, without generating moment of flexure.Dress is also triggered when tightening tie down screw simultaneously
Microswitch on microswitch seat, turntable can not power at this time, i.e., be applied with electic protection to turntable.
Detailed description of the invention:
Fig. 1 locking protecting device structure chart
Fig. 2 locking protecting device installation diagram
As shown in the following figure:
1, tie down screw 2, locking bracket 3, locking bed
4, adjustment plate 5, microswitch seat 6, microswitch are locked
7, table top 8, pedestal
Specific embodiment:
Below with reference to embodiment and compares attached drawing the invention will be further described.
A kind of locking protecting device for platform-type single shaft air-float turntable, including locking bracket, tie down screw, locking
Seat, microswitch seat, microswitch and locking adjustment plate.It is constituted: microswitch (6) is mounted on microswitch seat (5),
Locking bed (3) and locking adjustment plate (4) are mounted on microswitch seat (5) simultaneously, locking bracket (2) is secondly mounted on platform
On face (7), then will locking adjustment plate (4) and the part that is connected thereto as being integrally mounted on pedestal (8).It finally will lock
Tight screw rod (7) is screwed into locking bed (3) along locking bracket (2).Thickness by adjusting locking adjustment plate (4) can guarantee to twist
Tight tie down screw (7) triggers microswitch (6) simultaneously afterwards.
Working method: terminate that tie down screw is screwed into locking bed locking along locking bracket using when in turntable, be then turned off
Air supply system.Air supply system is then first opened before the use, after stable gas pressure, turntable can be powered on after unclamping tie down screw
Operation.
It is above that a kind of locking protecting device purposes for platform-type single shaft air-float turntable and assembly method are carried out
Explanation.
Claims (1)
1. a kind of locking protecting device for platform-type single shaft air-float turntable, it is characterised in that:
(1) locking protecting device is by locking bracket, tie down screw, locking bed, microswitch seat, microswitch and locking adjustment plate
Composition；
(2) locking bracket of locking protecting device is connected on the Table top able to be rotated of platform-type single shaft air-float turntable, locks adjustment plate
It is then connected on the pedestal of platform-type single shaft air-float turntable, when device use uses in pairs, at 180 ° of uniformly distributed installations.
