Description
Technical field
The utility model relates to a kind of gear mechanism, especially relates to a kind of being exclusively used in from what move an electric drill and changes the head gear mechanism.
Background technology
As everyone knows, hand-held charging double-headed electric drill in the market is also fewer comparatively speaking, and mostly adopts hand to change head.Bring many inconvenience for like this operating personnel's work, influenced operating efficiency and work quality.On the other hand, most in the market hand-held charging double-headed electric drill can't guarantee its transmission steadily, and its operating accuracy is not high, and integrated operation is poor, and is not suitable for the requirement of ergonomics, thereby influences operating efficiency.
Summary of the invention
The utility model mainly be at existing in prior technology can't be automatically more bit change, operating accuracy is low, integrated operation is poor, be not suitable for the technical problem of ergonomics requirement etc., provide a kind of can be automatically more bit change, operating accuracy height, favorable integrated operability, meet that ergonomics requires move an electric drill certainly change the head gear mechanism.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind ofly change the head gear mechanism from what move an electric drill, comprise main case and output support housing and be arranged on several drill bits of exporting the support housing front end, output support housing inside is provided with output shaft, output shaft rear end and power transmission shaft connect, it is characterized in that described main case front end is provided with annular slot, in the terminal annular position of bone button and annular slot that is provided with of output support housing; Be fixed with a locating shaft on the axis of described output support housing, the locating shaft other end is provided with bevel gear wheel, and bevel gear wheel is meshed with the bevel pinion that is arranged on the power transmission shaft front end.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 moves the bevel gear wheel engagement that makes the bevel pinion that is fixed on the power transmission shaft front end and be fixed on the locating shaft end by power transmission shaft backward; Through step-down after supply with direct current generator by power supply this moment, the transmission gear shift casing is exported through power transmission shaft, and the bevel pinion that power transmission shaft drives its front end rotates, thereby drives the bevel gear wheel that is meshed with it, thereby drive the output support housing along axis A rotation, realize 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, the center line of described power transmission shaft and output shaft is located on the same line.Guaranteed its transmission steadily, the operating accuracy height.
As preferably, the angle between the axis of described output support housing and the center line of output shaft is 45 °-55 °.Its whole operability is stronger, rational in infrastructure, and best angle is 50 °.
As preferably, described output support housing front end is provided with two drill bits at least, between the described drill bit separately angle be 95 °-105 °.Make the whole operability of product stronger, more meet the ergonomics requirement; Its best angle is 100 °.
Therefore, the utlity model has can be automatically more bit change, operating accuracy height, favorable integrated operability, meet characteristics such as ergonomics requires, reasonable in design, operating efficiency height.

Accompanying drawing 1 is a kind of structure cutaway view of the present utility model.
Accompanying drawing 2 is a kind of partial sectional views of B part in the utility model accompanying drawing 1.
Accompanying drawing 3 is a kind of partial sectional views of C part in the utility model accompanying drawing 1.
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 ofly change the head gear mechanism from what move an electric drill, 2, two drill bits of two drill bits that comprise main case 10 and output support housing 1 and be arranged on output support housing front end are 100 ° at conplane angle degree.Output support housing inside is provided with output shaft 3, and output shaft rear end and power transmission shaft 4 connect, and the center line of power transmission shaft and output shaft is located on the same line.The main case front end is provided with annular slot 5, in the terminal annular position of bone that is provided with 6 buttons of output support housing and the annular slot; Be fixed with a locating shaft 7 on the axis A of described output support housing, the locating shaft other end is provided with bevel gear wheel 8, and bevel gear wheel is meshed with the bevel pinion 9 that is arranged on the power transmission shaft front end.Angle between the axis A of output support housing and the center line of output shaft is 50 °.
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 moves the bevel gear wheel engagement that makes the bevel pinion that is fixed on the power transmission shaft front end and be fixed on the locating shaft end by power transmission shaft backward; Through step-down after supply with direct current generator by power supply this moment, the transmission gear shift casing is exported through power transmission shaft, and the bevel pinion that power transmission shaft drives its front end rotates, thereby drives the bevel gear wheel that is meshed with it, thereby drive the output support housing along axis A rotation, realize 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.
