Abstract
The utility model relates to a self-tapping screw repeating device, which is characterized in that the inner sliding sleeve of a tube body is connected with a screw driver base and a screw driver resetting pressure spring, and the screw driver base is provided with a through hole in order to pass through the shifting lever of a screw bin; a clamping spring fixed on the screw driver is clamped into the clamping groove of the shifting lever; one end of the tube body is provided with the screw bin with ten rotatable hole sites, a protective cover with a tapping screw outlet and a screw site inspecting hole, and a hole ring arranged in the screw bin is provided with a shifting wedge-shaped rack bar corresponding to the shifting lever. The utility model has the advantages that ten tapping screws can be filled in the utility model once, the utility model can carry out continuous operation and can be coupled and matched with the existing electric screw driver, the screw fastening position is accurate, and the utility model is suitable for the tapping screw fastening continuous operation.
Description
The utility model relates to and is used for fastening instrument, and the inner magazine of particularly a kind of usefulness transports the self-tapping screw running fire device of screw.
At present, assembling screw on its housings of product such as washing machine, refrigerator, television set or the sheet metal component generally all uses self-tapping screw, in other mechanical industries, as auto industry, aircraft industry, mounting screw also extensively adopts self-tapping screw on the non-ferrous metal product.Self-tapping screw is needn't machining internal thread on screw hole, directly self-tapping screw is screwed into screw hole, and operating efficiency is improved.But use self-tapping screw how to carry out by hand at present, relatively the effort, time-consuming, work efficiency is affected.Chinese patent 94207787.3 " screw rifle ", a kind of electric hand tool is provided, can with electric screwdriver (screw rifle) self-tapping screw be screwed into screw hole on the self-tapping screw screw position in storehouse of putting into the screw rifle one by one, thereby can reduce labor intensity, increase work efficiency.But, load self-tapping screw one by one, still influencing operating efficiency can not increase substantially.
The purpose of this utility model is, designs and produces a kind of self-tapping screw running fire device, and once many pieces of self-tapping screws of filling in electric screwdriver (screw rifle) can successively be screwed into the self-tapping screw operation, reduce the operation dead time, increase work efficiency.
Self-tapping screw running fire device of the present utility model is made up of cylindrical shell and screw storehouse, it is characterized in that, be provided with the guiding keyway in the cylindrical shell, sliding sleeve connects screwdriver pedestal and screwdriver reseting pressuring spring, is provided with through hole on the screwdriver pedestal, to pass the moving tooth bar in screw storehouse, spacing with split pin at moving tooth rod end head; Snap in the draw-in groove of moving tooth bar with being fixed on jump ring on the screwdriver pedestal; Be provided with the support spring tenon in the cylindrical shell, an end of cylindrical shell is provided with screwdriver pilot hole and screw storehouse seat, and rotating screw storehouse is set in the seat of screw storehouse, and screw storehouse seat is hinged with the protecting cover that has self-tapping screw outlet, is provided with a nail position inspection opening at the self-tapping screw port of export of protecting cover; The screw storehouse is provided with position, 10 holes, and the mesopore ring wall is provided with the displacement wedge type tooth bar of answering with the moving tooth pole pair.
Using method of the present utility model is, with the one that is threaded, the screwdriver that the motor transmission shaft of electric screwdriver drives stretches in the cylindrical shell, inserts screwdriver back-moving spring central authorities with the casing of screwdriver pedestal and electric screwdriver; Pull the protecting cover jump ring, open protecting cover, on the screw storehouse, fill self-tapping screw; The self-tapping screw specification can be 4～5 millimeters of diameters, and 5～30 millimeters of length are covered tight protecting cover again; Starter motor, electric screwdriver is pressed in position, alignment screw hole, and to front slide, the screwdriver back-moving spring is compressed the screwdriver pedestal along cylinder inboard wall, and the moving tooth bar is advanced forward simultaneously, and stirs the inclined-plane of the displacement tooth bar of screw storehouse mesopore, makes the screw storehouse rotate 18 degree; After the moving tooth bar put in place, the jump ring on the screwdriver pedestal was strutted by the support spring tenon on the cylindrical shell, the moving tooth bar no longer by the screwdriver pedestal advance forward drive; The screwdriver pedestal continues to advance, and electric screwdriver pushes against self-tapping screw, screws screw, finishes the self-tapping screw terminal operation.
Regain electric screwdriver, the screwdriver back-moving spring drives screwdriver and retreats, jump ring on the screwdriver pedestal snaps in the draw-in groove of moving tooth bar, driving the moving tooth bar retreats, the moving tooth bar passes through with displacement tooth bar one side again, makes the screw storehouse rotate 18 degree, at this moment, can press electric screwdriver, enter the terminal operation of second self-tapping screw.
The utility model has the advantages that: once can load 10 pieces of self-tapping screws, terminal operation is increased work efficiency continuously; Can be connected supporting, easy to use with present widely used electric screwdriver; Volume is little, and is in light weight, and structure is reasonable, and aesthetic in appearance, the holding screw position is accurate.Being applicable to that self-tapping screw is fastening works continuously.
Below in conjunction with drawings and Examples, the utility model is further described.
