Abstract
The invention belongs to the technical field of measurement, and relates to a two-shaft automatic turntable structure with built-in air ducts. The structure is used for ventilating measured parts and dissipating the heat of the measured parts. By building the air ducts in a turntable shaft and realizing that the air ducts pass through the inner and outer shafts by utilizing two-stage rotary joints of the air ducts, the structure adapts to the ventilation under the condition of continuous rotation of the two shafts; one ventilating rotary joint is installed at one side of a tilting shaft system, and the other side is used for a conducting ring and other electrical channels; the other rotary joint is installed in the middle of an azimuth shaft by adopting a unique air box structure; the shaft end part of the azimuth shaft is reserved for the conducting ring and other electrical channels; and the rotary joints enable the air ducts to complete dynamic and static transformation. The problem of collision between the air ducts of the azimuth shaft system and the electrical channels (the conducting ring and cables) is solved by adopting the divided chamber structure; and the two shafts can provide positioning at any angle, thus ensuring air supply while realizing infinite rotation, and meeting the test requirements for continuous rotation and the angular rate.

Background technology
At present, because the volume of many test products is little, power density is large, needs ventilation and heat in use, must rely on turntable to carry out while testing under angular motion condition.While carrying out angular motion test for the measured piece needing ventilation and heat on two axle automatic turntables; be placed in turntable outside to the airduct of measured piece air feed; directly be connected with measured piece; on automatic turntable under service condition time; when azimuth axis and sloping shaft large rotation angle, airduct is very easily wrapped on turntable, causes turntable to exceed moment scope and shuts down and damage airduct; when serious, also can damage measured piece and turntable.Meanwhile, external airduct has also limited the range of movement of angle, does not reach the test request of continuous rotation and angular speed.
Summary of the invention
The object of the invention is to propose a kind of turntable and airduct and do not produce interference, need the measured piece ventilating can on turntable, to realize the two axle automatic turntable structures in the built-in air channel of continuous rotation and speed trial.
Technical solution of the present invention is, outside air supply line is connected with the air inlet of turntable, air inlet is fixed on the axle head housing of sloping shaft of turntable, between air inlet and sloping shaft, add 1 rotating seal ring, sloping shaft is that hollow structure forms air channel, sloping shaft is connected with the housing of azimuth axle, annular wind box is installed on orientation housing, one end of wind box communicates with the hollow air channel of sloping shaft, between the other end of wind box and orientation rotation axle, with two rotating seal rings, be connected, orientation rotation axle is hollow-core construction, its middle part is with stopping up shutoff, form air channel and electrical path, on the axial wall of the air passage portion of orientation rotation axle and wind box junction, have four radially fresh air inlets, between each fresh air inlet, be provided with axial inclined hole, communicate with electrical path and the turntable table top of orientation rotation axle, center wind ejection mouth on the outlet in the air channel of orientation rotation axle and turntable table top joins.Air outlet is connected with the bottom air inlet of measured piece.
Annular wind box is installed on described orientation housing, and one end of annular wind box is positioned at the position in the air channel of orientation rotation axle, and annular wind box is connected with two rotating seal rings with the junction, air channel of orientation rotation axle.
Annular wind box is installed on described orientation housing, and annular wind box is looped around on orientation rotation axle, and the top and bottom of annular wind box are realized sound with a rotating seal ring with orientation rotation axle respectively and are connected.
Described has four radially fresh air inlets on the axial wall between orientation rotation axle and the top and bottom of annular wind box, is communicated with the air channel of annular wind box and the air channel of orientation rotation axle, and every two are radially provided with axial inclined hole between fresh air inlet.
The advantage that the present invention has and beneficial effect, the present invention can provide required ventilation and heat and the integrated condition of angular motion environment to measured piece.By ventilating duct is built in turntable shaft, utilize the two-stage rotary joint in air channel to solve air channel and pass through inside and outside diaxon, adapted to the ventilation under the continuous rotation condition of diaxon.A ventilation rotary joint is arranged on a side of sloping shaft system, and opposite side can be used for the electrical path such as conducting ring to be used.A rotary joint adopts unique wind box structure to be installed on the middle part of azimuth axis, and the axial end portion that reserves azimuth axis is used for electrical path such as conducting rings.Rotary joint makes ventilating duct complete the conversion between sound, and the present invention adopts chamber structure to solve the collision problem of azimuth axle air channel and electrical path (conducting ring and cable).The winding producing when the airduct that has solved original product is tested on automatic turntable damages problem.Diaxon can provide positioned at arbitrary angles, guarantees air feed when unlimited rotary simultaneously, reaches the test request of continuous rotation and angular speed.
