Abstract
The utility model relates to a transmission mechanism, in particular to a transmission shaft device specially for an automatic head-changing electric drill, and consists of a direct current motor, a gearbox box, a transmission shaft and an output shaft; the gearbox body is arranged between the direct current motor and the transmission shaft; the output shaft is arranged in the front end of the transmission shaft; the utility model is characterized in that a flat square hole is arranged in the output position of the inside of the gearbox body; the back end of the transmission shaft is embedded in the flat square hole; the ends of the transmission shaft are provided with bevel gears; a gap is maintained between the transmission shaft and the output shaft. The utility model is characterized in relatively smooth transmission, high working precision, reasonable structure, simple operation, etc.
Description
Technical field
The utility model relates to a kind of transmission mechanism, especially relates to a kind of being exclusively used in from the driveline of moving an electric drill.
Background technology
As everyone knows, the transmission system of existing in the market double end Charge) adopts " three sections axle transmission " mostly, and promptly the double end Charge) uses three sections connecting axles to finish from the gearbox to the output, and it comprises power transmission shaft, coupling spindle, output shaft; This type of product structure complexity and can't guarantee that transmission steadily and operating accuracy.Therefore the utility model only adopts two axles to finish transmission: power transmission shaft and output shaft clutch are connect, promptly better guaranteed the steady of transmission, the precision when having improved work again greatly.
Summary of the invention
The utility model mainly be at existing in prior technology transmission inadequately steadily, the technical problem of low, the complex structure of operating accuracy, complicated operation etc., provide a kind of transmission relatively steadily, operating accuracy high, rational in infrastructure, easy and simple to handle move an electric drill driveline certainly.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of from moving an electric drill driveline, be made of direct current generator, gearbox body, power transmission shaft, output shaft, gearbox body is arranged between direct current generator and the power transmission shaft; Output shaft is arranged on the power transmission shaft front end, it is characterized in that the inner carry-out bit of described gearbox body is equipped with flat square hole, and the power transmission shaft rear end is embedded in flat square hole, and the power transmission shaft end is provided with bevel gear; Leave the space between described power transmission shaft and the output shaft.From moving an electric drill more during bit change, the operator only needs by moving a gauge tap, changes the jump ring of pushing down on the power transmission shaft gauge tap end and meshes by mobile backward bevel gear that is fixed on the power transmission shaft front end and the bevel gear wheel that is fixed on the output support housing of making of power transmission shaft; Supply with direct current generator by power supply this moment after the pcb board step-down, the transmission gear shift casing is exported through power transmission shaft, and power transmission shaft drives the output support housing along axis A rotation, thereby realizes from the purpose of moving head; When unclamping when changing gauge tap, power transmission shaft relies on its stage casing back-moving spring to be pushed to front end, makes the engagement of power transmission shaft and output shaft, and this moment, power supply was supplied with direct current generator, and the transmission gear shift casing drives output shaft output through power transmission shaft, enters duty.
As preferably, described power transmission shaft front end is provided with interior six pin holes.
As preferably, described output shaft rear end is provided with the six pin heads that the interior six pin holes with the setting of power transmission shaft front end are complementary.Power transmission shaft and output shaft engagement, promptly the interior six pin borehole jacks of power transmission shaft front end are on the turret head of output shaft rear end, and it is rational in infrastructure, connects stable.
As preferably, described power transmission shaft stage casing is provided with back-moving spring.Back-moving spring plays the effect that power transmission shaft is resetted.
As preferably, the horizontal range that leaves the space between described power transmission shaft and the output shaft is 1cm--4cm.It is rational in infrastructure, and space structure is provided with compactness.
Therefore, the utlity model has characteristics such as transmission is steady relatively, operating accuracy is high, rational in infrastructure, easy and simple to handle.

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
A kind of oneself moves an electric drill driveline, is made of direct current generator 1, gearbox body 2, power transmission shaft 3, output shaft 4, and gearbox body is arranged between direct current generator and the power transmission shaft; Output shaft is arranged on the power transmission shaft front end, gearbox body inside is provided with flat square hole 5, the flat quadrate part in power transmission shaft rear end divides in the flat square hole of insertion, and the flat quadrate part in power transmission shaft rear end divides and can move forward and backward in the flat square hole of gearbox outgoing position, and the power transmission shaft end is provided with bevel gear 6; Leave the space between power transmission shaft and the output shaft.The power transmission shaft front end is provided with interior six pin holes 7; The output shaft rear end is provided with the turret head 8 that is complementary with interior six pin holes.The power transmission shaft stage casing is provided with back-moving spring 9.The horizontal range that leaves the space between power transmission shaft and the output shaft is 3cm.
From moving an electric drill more during bit change, the operator only needs by moving a gauge tap 10, changes the jump ring of pushing down on the power transmission shaft gauge tap end and meshes by mobile backward bevel gear that is fixed on the power transmission shaft front end and the bevel gear wheel 12 that is fixed on the output support housing 11 of making of power transmission shaft; Through step-down after supply with direct current generator by power supply this moment, and the transmission gear shift casing is exported through power transmission shaft, and power transmission shaft drives the output support housing along axis A rotation, thereby realizes from the purpose of moving head; When unclamping when changing gauge tap, power transmission shaft relies on its stage casing back-moving spring to be pushed to front end, make power transmission shaft and output shaft mesh, the interior six pin borehole jacks that are the power transmission shaft front end are on the turret head of output shaft rear end, this moment, power supply was supplied with direct current generator after the pcb board step-down, the transmission gear shift casing drives output shaft output through power transmission shaft, enters duty.
