Abstract
The invention discloses a pneumatic motor accelerating mechanism for a pneumatic insert nut tool. In the mechanism, a clockwise rotary channel and a counterclockwise channel are arranged on a stator; a rotor is arranged in a cavity; a front press end cover and a rear press end cover are arranged at the left and the right of the stator respectively; a clockwise air inlet and a counterclockwise air inlet are arranged at one side of the rear end cover, and are communicated with the clockwise channel and the counterclockwise channel on the stator; the clockwise channel and the counterclockwise channel are communicated with the inner of the cavity from two sides of the rotor respectively; inlets of the clockwise channel and the counterclockwise channel are provided with a check valve respectively, and each check valve is controlled by a valve sphere. The mechanism has the advantages that the conventional one-way entrance is changed into a two-way entrance, the rotor is positioned in a medium state, and the friction resistance of the two end faces of the rotor in rotation is reduced to ensure that the rotating speed reaches the maximum value and the high-speed rotation capability of the rotor is improved. Therefore, the pneumatic motor accelerating mechanism for the pneumatic insert nut tool has stable rotation, high rotating speed and large clockwise and counterclockwise rotating forces, and can work normally under a condition of air pressure fluctuation.
Description
Technical field
The present invention relates to a kind of pneumatic Insert Nut instrument air motor speed-raising mechanism.
Background technique
Insert Nut is promoted the use of, solved the fastenings difficult problem on the thin plate, but be to use hand-operated tools to waste time and energy, the riveted joint effect is undesirable, and pneumatic Insert Nut instrument comes out, overcome the disadvantage of hand-operated tools, pneumatic tool all is the unidirectional pressurized air that enters in the market, the rotation of promotion rotor, the motor shake is big for this reason, and balanced rotation is poor during rotor startup, cause rotor spin friction resistance in stator also big, can't improve rotating speed, run into the big stainless steel hexagonal Insert Nut work of pulling force sometimes and finish and incomplete phenomena occurs moving back, thereby correctly handle motor rotary speed well and the carry-over moment relation is the key of pneumatic Insert Nut instrument.
In view of the foregoing, be necessary the pneumatic Insert Nut instrument air motor speed-raising mechanism of a kind of rotating speed height newly developed, stability of rotation.
Summary of the invention
Technical problem to be solved by this invention is, at existing Insert Nut pneumatic tool air motor speed-raising mechanism spinner velocity slowly, steadily and be subjected to the big problem of frictional force, do not provide a kind of and rotate steadily, rotating speed is fast pneumatic Insert Nut instrument air motor speed-raising mechanism.
In order to solve the problems of the technologies described above, the present invention adopts following technical proposal:
A kind of Insert Nut pneumatic tool air motor speed-raising mechanism, comprise housing, stator, rotor, blade, front cover, rear end cover and preceding push rod and back push rod, the housing rear end is provided with the back push rod, be provided with the columniform cavity of core shift in the stator, stator is provided with clockwise passage and inverting channel, several exhaust ports are set on the stator, rotor is set in the cavity, blade is set on the rotor, be equipped with about stator and press front cover and rear end cover, front cover, rear end cover is equipped with left and right sides bearing, and with rotor two ends mutually load connect in the rotating shaft, rear end cover is provided with clockwise inlet hole and counter-rotating inlet hole on one side, two gas-entered passageways on clockwise inlet hole and counter-rotating inlet hole and the stator are connected, clockwise passage and inverting channel lead in the cavity from the both sides of rotor respectively, make clockwise inlet hole and counter-rotating inlet hole when entering pressurized air respectively in the past rear end ventilate simultaneously, thereby form the power of general opposite sign but equal magnitude, make rotor be positioned at intermediateness, reduce rotor frictional force when rotated and between the biend thus, reach the speed-raising purpose.
The ingress of clockwise passage and inverting channel respectively is provided with an one-way valve, each one-way valve is respectively by a valve ball control, be provided with spring between two valve balls, control valve ball sealing gas, front valve ball contacts with the sinciput rod rear end, back valve ball contacts with the front end of back push rod, and a gas-entered passageway is communicated with the housing endoporus with source of the gas.Push rod pushes up inwards before treating, promptly fast unseat the valve ball makes gas enter clockwise passage rapidly, it is clockwise to promote rotor high-speed simultaneously from biend, treats a push rod top inwards, back, promptly backs down the valve ball that contacts with back push rod, allow gas enter inverting channel, make biend promote the rotor high-speed counter-rotating simultaneously.
Rotor both sides in housing are provided with left bearing and right bearing, and preceding push rod is set in the SMIS hole between left bearing and the right bearing, and preceding push rod passes rotor.
Advantage of the present invention is: make original unidirectional entering into two-way entering, allow rotor be positioned at intermediateness, reduce rotor two end-face friction resistances when rotated, make rotating speed reach maximum value, improve the rotor high-speed rotatory power.Therefore, not only rotation of the present invention steadily, and rotating speed height, and clockwise and anticlockwise power is also big, can be under the air pressure fluctuation situation proper functioning.
