Abstract
The utility model relates to an engineering impact hammer, which is characterized in that an electric motor is connected with a gear pinion via a flexible shaft to brake a speed gear, thus forming the engineering impact hammer.
Description
The utility model relates to a kind of hammer, particularly relates to a kind of engineering jump bit.
At present, known engineering jump bit is that motor is held in the hammer body, makes hammer body increase the weight of, strengthen, effort, inconvenience during operation.While motor single-use, efficient is low.
The purpose of this utility model provides a kind of engineering jump bit, and motor is separated in hammer body, makes hammer body light, small and exquisite, but while motor multipurpose.
The purpose of this utility model is to realize like this, have flexible axle, motor, drill hammer, power transmission shaft, change-speed gearing, pinion, connect in turn, it is characterized in that in turn connect in succession by motor and pinion, change-speed gearing, power transmission shaft, drill hammer for flexible axle.Flexible axle and pinion connecting place are provided with connecting bolt, can be with flexible axle and the dialysis freely of pinion connecting place, and pinion connects and the braking change-speed gearing.
Because adopt such scheme, not only hammer body is light small and exquisite, efficient increases, and flexible axle also can be complementary with electric tool such as vibrating head after the dialysis freely, reaches a multiduty effect of motor.
Below in conjunction with drawings and Examples utility model is further specified.
Fig. 1 is the schematic diagram of the utility model embodiment
Fig. 2 is a middle hammer body structural map embodiment illustrated in fig. 1
Among the figure, 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. bearing (11) lash space of shock club of motor of pinion of connecting bolt of change-speed gearing of power transmission shaft of drill hammer of hammer body of flexible axle
In the embodiment shown in fig. 1,8. a flexible axle 1. end is connected motor, and 2. 6. an end connecting bolt be fixed on hammer body, 3. is drill hammer
Fig. 2 is a hammer body internal structural map among the embodiment illustrated in Figure 1,7. 1. flexible axle imbed pinion, and it is 6. fastening to be connected bolt, and change-speed gearing is 5. 7. tightly identical with pinion, 3. 4. power transmission shaft be integral with drill hammer, and 10. bearing one end leaves lash space (11).
Claims (3)
