Abstract
A graphite rotor ring type trisection semi-circular key seal clamping structure is characterized by consisting of a spindle, a positioning outer sleeve, a graphite rotor, a ring type trisection semi-circular key and a positioning inner sleeve. The spindle is in threaded connection with the positioning outer sleeve, the graphite rotor penetrates through the positioning inner sleeve and is exposed out of a positioning ring groove, the ring type trisection semi-circular key is combined and mounted inside the positioning ring groove of the graphite rotor, the graphite rotor is downward so as to lead the ring type trisection semi-circular key to drop into a counter bore of the positioning inner sleeve, the positioning inner sleeve and the positioning outer sleeve are in movable-engagement threaded connection, and the positioning inner sleeve after being assembled is arranged on an upper stop point of the positioning outer sleeve. The graphite rotor ring type trisection semi-circular key seal clamping structure is reliable in operation due to the reasonable positioning and clamping structure.
Description
Technical field
The utility model belongs to the technical field of aluminium alloy aluminium crystal refining equipment sealing, the particularly ring-like three equal parts woodruff key of graphite rotator clips locking structure.
Background technology
At present, the aluminium crystal refines chemical refining of branch and mechanical refining.Chemical refining is serious because of its industrial pollution, just progressively eliminates.Mechanical refining equipment---the rotation getter is to influence aluminium alloy casting casting quality key equipment.(300 ℃---500 ℃) sealing problem never has fine solution because this equipment seal member work under bad environment, and degree is not influenced for the casting quality.
Rotation getter graphite rotator sealing clamping mode has a variety of, adopts more have three kinds: the one, and screw thread clamps; The 2nd, Morse's taper clamps; The 3rd, cam clamps.
Screw thread clamps, because easily the processing employing is more, getter graphite rotator material is soft partially, and screw clamp tightening seal mode is sealing time weak point effectively, often is that rotor does not also have bad screw thread clamping part to leak gas, and can only change.
Morse's taper clamps screw clamp bind mode location and is better than the screw thread clamping, good positioning effect, and the sealing time is short, often is that rotor does not also have the bad part that is threaded to leak gas, and can only change.
Cam clamps and has solved the rib-loop clamping inefficacy that counter-rotating causes, because point location, effective storage life is short.
Above-mentioned three kinds of methods all can not fine solution be rotated getter graphite rotator sealing problem, and therefore each seal failure all influences alloy aluminum aluminium crystal and refines quality and then influence product quality.
Summary of the invention
The utility model purpose provides the ring-like three equal parts woodruff key of a kind of graphite rotator clips locking structure.
The technical solution of the utility model is achieved in that
The ring-like three equal parts woodruff key of graphite rotator clips locking structure, it is characterized by: it is by main shaft, the location overcoat, graphite rotator, ring-like three equal parts woodruff key, cover is formed in the location, main shaft is connected with the location sleeve thread, graphite rotator is passed cover in the location, expose positioning ring groove, ring-like three equal parts woodruff key combination is installed in the graphite rotator positioning ring groove, graphite rotator falls into ring-like three equal parts woodruff key downwards in the counterbore of cover in the location, cover is a spiral marking connection movingly with the location overcoat in the location, will overlap in the location of assemble to be installed to the top dead centre of locating overcoat.
The utility model is because the locating clip locking structure is reasonable, reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
The ring-like three equal parts woodruff key of graphite rotator clips locking structure, it is characterized by: it is by main shaft 1, location overcoat 2, graphite rotator 3, ring-like three equal parts woodruff key 4, cover 5 is formed in the location, main shaft 1 is threaded with location overcoat 2, graphite rotator 3 is passed cover 5 in the location, expose positioning ring groove, ring-like three equal parts woodruff key 4 combinations are installed in the positioning ring groove of graphite rotator 3, graphite rotator 3 falls into ring-like three equal parts woodruff key in the counterbore of cover 5 in the location downwards, cover 5 is spiral marking connections movingly with location overcoat 2 in the location, is installed to the top dead centre of locating overcoat 2 with overlapping 5 in the location of assemble.
Embodiment:
Shown in Figure 1, the utility model can adopt ring-like three equal parts woodruff key clamping structure.Be circular orientation between graphite rotator and the chuck.Positioning form is: main shaft 1 is threaded with location overcoat 2, graphite rotator 3 is passed cover 5 in the location, expose positioning ring groove, ring-like three equal parts woodruff key 4 combinations are installed in the positioning ring groove of graphite rotator 3, graphite rotator 3 falls into ring-like three equal parts woodruff key in the counterbore of cover 5 in the location downwards, cover 5 is spiral marking connections movingly with location overcoat 2 in the location, is installed to the top dead centre of locating overcoat 2 with overlapping 5 in the location of assemble, installs.
