Abstract
The utility model is related to an impact electric drill, which is added a steel bushing on the shell of the known impact electric drill. The impact electric drill is with the structure of the electric engine unit assembly, the driving device ect. are connected with each other in order, and the impact hammer and spring is located in the steel bushing. When the impact gear and the fixing gear mesh with each other, the driving device drives the output axle to rotate, in the meantime, makes the output shaft move vertically, at the moment, the impact hammer is knocking one end of the output continuously under the operation of the spring in the steel bushing, thus the aim of automatic impact can be obtained.
Description
Affiliated technical field
The utility model relates to a kind of electric tool, especially a kind of electric impact drill that is provided with jump bit.
Background technology
At present, known electric impact drill is depended merely on a fixed gear that impacts gear and be complementary with this gear that is installed in the output shaft rear end.Facts have proved that this electric impact drill does not have the effect of direct impact at all, but will lean on people's thrust just can reach the purpose of impact fully.Though and existing impact electric hammer is effective, complex structure costs an arm and a leg.
Summary of the invention
The purpose of this utility model provides a kind of electric impact drill with jump bit, and it not only saves time, laborsaving, and simple in structure, cheap.
The utility model is achieved like this: it mainly comprises: shell, motor assembly, transmission device and percussion mechanism.Described transmission device is made up of shaft gear, reduction gearing, impact gear and output shaft.Described percussion mechanism is provided with impact gear, fixed gear, the steel bushing of Dou tooth by end face and the jump bit and the spring that are located in this steel bushing are formed.
Owing to adopt such scheme, can reach the purpose of automatic impact during use, simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a cutaway view of the present utility model.
1. shells, 2. motor assemblies, 3. shaft gears, 4. reduction gearing 5. are impacted gear 6. output shafts 7. output sleeves 8. springs 9. fixed gears 10. steel bushings 11. jump bits 12. springs 13. speed-regulating switch 14. power line covers among the figure
The specific embodiment
In Fig. 1, the shaft gear (3) of motor assembly (2) output meshes with the big increment of reduction gearing (4), the little increment of reduction gearing (4) and impact gear (5) engagement, impacting gear (5) is fixed on the output shaft (6), one of this output shaft (6) is installed in the output sleeve (7), the other end links to each other with jump bit (11) by the centre bore of fixed gear (9), is provided with spring (8) on this output shaft (6).Jump bit (11) and spring (12) place respectively in the steel bushing (10), and this steel bushing (10) is installed in fixed gear (9) back side, and are separately fixed in the shell (1) with speed-regulating switch (13) and power line cover (14).
Be respectively equipped with the Dou tooth at the end face that impacts gear (5) and fixed gear (9).When impacting the Dou tooth engagement of gear (5) and fixed gear (9), when transmission device drives output shaft (6) rotation, output shaft (6) is vertically moved, at this moment, jump bit (11) will constantly knock an end of output shaft (6) under the effect of steel bushing (10) inner spring (12), thereby reaches the purpose of automatic impact.
Claims (1)
- A kind of electric impact drill, it mainly comprises: shell (1), motor assembly (2), shaft gear (3), reduction gearing (4), impact gear (5) and output shaft (6), it is characterized in that: be provided with steel bushing (10) at fixed gear (9) back side, in steel bushing (10), be provided with jump bit (11) and spring (12).
