Technical field
The utility model relates to a kind of oscillator, specifically, particularly relates to a kind of new type of airflow oscillator.
Background technology
Oscillator is a device not needing external signal to encourage, self just direct current energy can be converted into AC energy.Generally be divided into positive feedback and negative resistance type two kinds.So-called " vibration ", its connotation just infers interchange, and oscillator contains process and the function that never oscillates to vibration.Can complete from direct current energy to alternating current transformation of energy, such device just can be called " oscillator ".
The effect of oscillator is that direct current is become alternating current.It has a lot of purposes, generates electromagnetic waves in radio broadcasting and communication facilities, and clocking in microcomputer, produces high-frequency alternating current in mu balanced circuit.
But a oscillator can not measured comparatively accurate accessory at present, thus improves the qualification rate of product.
Therefore those skilled in the art are devoted to develop a kind of a oscillator can measured accurate accessory.
Utility model content
For achieving the above object, the utility model provides a kind of a oscillator can measured accurate accessory.
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of air-flow oscillator, comprises housing and cover plate, offers circular groove on the housing; The bottom of described groove is provided with the first threaded mounting hole; Steel ball is provided with in described groove; Air input hole and air delivery outlet is provided with in the bottom of described housing; This air delivery outlet communicates with described groove;
Described air input hole is provided with the air input hole lug boss with through hole; The internal diameter of this air input hole lug boss is less than the internal diameter of described air input hole; Described air input hole communicates with described air input hole lug boss, and described air input hole is connected by described input hole lug boss and groove;
Described cover plate is provided with second threaded mounting hole corresponding to described first threaded mounting hole size; This cover plate is arranged on the opening part of described groove, and described cover plate is connected with described housing with the second threaded mounting hole through the first threaded mounting hole by screw; The opening of described groove is by described cover closure; Groove is made to form a seal chamber.
Adopt above technical scheme, by the connection of cover plate and housing, make groove form the cavity of a sealing, steel ball is arranged in cavity, air is inputted from air input hole, by air, steel ball is promoted, make steel ball springing in the cavities, when the saturation of the air in seal chamber, unnecessary air is just released from air outlet aperture, can contact with the raceway groove of test product accurately when steel ball is in springing, and complete accurate measurement, improve the qualification rate of product.
Conveniently processing, described cover plate is circular configuration.
In order to ensure the sealing property of cavity, make measurement more accurate, described cover plate comprises the first web joint and the second web joint; This first web joint and the second web joint are positioned at the same center of circle, and the diameter of described first web joint is greater than the diameter of described second web joint; Described second web joint is identical with the diameter of described groove, and this second web joint is arranged in described groove, and the end face of described first web joint and the end face of described housing are fitted.
In order to improve the firmness of cover plate, facilitate the production and processing of cover plate, described first web joint and the second web joint are structure as a whole.
The beneficial effects of the utility model are: a oscillator that the utility model can be measured accurate accessory.Have structure and improve product percent of pass, structure simply waits beneficial effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is covering plate structure schematic diagram of the present utility model.
