Abstract
The invention relates to an unloading mechanism for large door vibration isolation of a space environment simulator. An unloading motor is connected with an unloading shaft through an unloading transmission system and drives the unloading shaft to rotate. A cam is arranged on the unloading shaft. When the cam rotates, an upper hung piece and a lower hung piece which are hung on the cam can be driven to vertically move in a reciprocating mode, and therefore a large door is unloaded and loaded. According to the unloading mechanism, the space environment simulator is isolated from external vibration and meanwhile logic interlocking protection of large door unloading and loading motions and the vacuum degree of a vacuum container is achieved.
Description
Technical field
The invention belongs to space environment simulation field, be specifically related to a kind of discharge mechanism for the vibration isolation of space simulator gate.
Background technology
Spacecraft needed to carry out the reliability that sufficient space environment test is verified spacecraft before transmitting.The vacuum of the main virtual space of space simulator, the cold environment such as black, its agent structure is vacuum tank.Vacuum tank generally comprises main cylinder and gate, and the door-opening mechanism at gate is the special equipment of the large door switch of implementation space environment simulator vacuum tank.Under door opening state, gate and main cylinder are relatively independent; Close the door and vacuumize under state, gate and main cylinder adhesive become one, if the uneasy load/unload mechanism of container, extraneous vibration load can be delivered to vacuum tank by door-opening mechanism.
Vacuum tank door-opening mechanism function is in the past comparatively single, can not be applicable to the space simulator of specific (special) requirements.Such as the Space Environment Simulator for optical device vacuum thermal test, for guaranteeing the stable precision of optical device, vibrations and the vacuum tank that need space simulator vacuum tank be produced by external staff or plant equipment are isolated.For the problems referred to above, be necessary to design a kind of door-opening mechanism with discharge mechanism.
Summary of the invention
The object of the present invention is to provide a kind of can be by the discharge mechanism that opens the door of the load such as external environment condition vibration and space simulator container gate isolation.For reaching above object, the technical solution used in the present invention is:
A kind of feel trim actuator for the vibration isolation of space simulator gate, comprise: movable motor, walking transmission system, walking driving shaft, road wheel, syndeton, unloading motor, unloading transmission system, unloading axle, hanging structure, lower bearing pin, guide rail, wherein walking transmission system and walking driving shaft are installed in syndeton top, and by road wheel across on guide rail, unloading motor, unloading transmission system and unloading axle are installed in syndeton bottom, hanging structure upper end and the interlock of unloading axle, lower end is connected with space simulator gate by lower bearing pin.
More specifically, described feel trim actuator also comprises the travel switch being arranged on guide rail.
More specifically, described hanging structure comprises hanging piece and lower hanging piece, upper hanging piece upper end and the interlock of unloading axle, and lower end is connected with lower hanging piece by upper pin, lower hanging piece upper end is suspended on unloading axle by upper hanging piece, and lower end is connected with space simulator gate by lower bearing pin.
More specifically, the door-opening mode at described space simulator gate is opened for suspention sidesway is flat.
The present invention has following beneficial effect:
Compare with existing door-opening mechanism, the feel trim actuator that opens the door of the present invention, in implementation space environment simulator and external vibration isolation, has also been realized gate unloading and has been loaded the logical interlock protection of moving with vacuum tank vacuum.
Accompanying drawing explanation
Fig. 1 is the feel trim actuator front view for the vibration isolation of space simulator gate of the present invention;
Fig. 2 is the feel trim actuator lateral view for the vibration isolation of space simulator gate of the present invention;
The specific embodiment
As illustrated in fig. 1 and 2, the feel trim actuator of a kind of space simulator gate vibration isolation, comprise: movable motor 1, walking transmission system 2, walking driving shaft 3, road wheel 4, syndeton 5, unloading motor 6, unloading transmission system 7, unloading axle 8, upper hanging piece 9, lower hanging piece 10, lower bearing pin 11, upper pin 12, cam 13, travel switch 14 and guide rail 15, wherein walking transmission system 2 is installed on syndeton 5 tops, walking driving shaft 3, and pass through road wheel 4 across on guide rail 13, unloading motor 6 is installed in syndeton 5 bottoms, unloading transmission system 7, unloading axle 8, upper hanging piece 9 upper ends and 8 interlocks of unloading axle, lower end is connected with lower hanging piece 10 by upper pin 12, lower hanging piece 10 upper ends are suspended on unloading axle 8 by upper hanging piece 9, lower end is connected with gate by lower bearing pin 11.
Unloading motor 6 is connected unloading axle 8 and is driven unloading axle 8 to rotate by unloading transmission system 7.Unloading axle 8 is provided with cam 13, when cam 13 rotation, can drive the upper hanging piece 9 and the lower hanging piece 10 that are suspended on cam to pump, thereby realize unloading and the loading at gate.When vacuum reaches desired value; unloading motor 6 receives instruction; drive unloading axle 8 to rotate; band moving cam 13 rotates to assigned address; trigger travel switch 14; and return to halt instruction to unloading motor 6, and thereby realize unloading, load the logical interlock protection between action and the vacuum of vacuum tank, can effectively avoid false triggering.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned embodiment according to conception of the present invention and change and revise; when its function producing does not exceed spiritual that manual and accompanying drawing contain yet, all should be within protection scope of the present invention.
