Description
Technical field
The present invention relates to a kind of hand held power machine, this hand held power machine can be used as hammer drill and rig, and is equipped with drive motors and beater mechanism is used for rotatably and hammering ground or impact the ground driven tool.
Background technology
Described a kind of hand held power machine that is constructed to hammer drill in DE 10 2,005 047 600 A1, it can be used to different operational modes.Can be used as on the one hand the hammer drill operation, wherein the actuation movement of drive motors can be transferred on the clamping dop that holds instrument by the rotating driving device that can connect and can turn-off and by beater mechanism.Iff beater mechanism is effectively, and rotating driving device is not effectively, and then hammer drill is in the pricker cutter pattern.On the contrary, also activated beater mechanism if both activated rotating driving device, then hammer drill operates in the percussion drill pattern.In the configuration of another switch, beater mechanism do not work and only rotating driving device be effectively, thereby hammer drill operates in the rotary drilling pattern.
The known in addition hand held power machine that is equipped with torque limiter, it bears the function of overload clutch, so that the power of taking between the device above interruption motor driver and instrument under the situation of overload torque in the torque of being transmitted flows.This hand held power machine that is configured electric screw driver has for example been described in DE 10 2,004 058 809 A1.Can be screwed into screw by identical torque by torque limiter.
Summary of the invention
From prior art, task of the present invention is, makes the hand held power machine that is constructed to hammer drill have additional operation function.
According to the present invention, described task solves by the feature of claim 1.Dependent claims provides the improvement project that meets purpose.
According to the present invention, hand held power machine both can be used as hammer drill and also can be used as rig, and had drive motors and beater mechanism.Advantageously, rotating driving device and beater mechanism are configured to respectively to connect maybe can be turn-offed, so that can realize different functions.For example, when rotating driving device is not worked and only beater mechanism is effective, can realize the operation of pricker cutter.Under the situation that rotating driving device also is activated, obtain the hammer drill function.Under the situation of turn-offing beater mechanism, it is in service that hand held power machine is in pure brill formula.
In addition, in hand held power machine according to the present invention, be provided with decelerator and torque clutch in the transmission path between drive motors and instrument storing apparatus and be used to limit the torque that can transmit, wherein instrument is contained in the described instrument storing apparatus.In the ideal case, can change torque clutch between operating position and off-position, torque limit lost efficacy in described off-position.Perhaps can mechanically cross over decelerator, thereby can between off-position and operating position, change speed changer equally, and/or can regulate the different gearratio in the decelerator.Decelerator can move described hand held power machine with the rotating speed lower than pure brill formula operation as the formula of boring screwdriver in the operating position or under the gearratio of corresponding adjusting.The torque that torque clutch is guaranteed in the pattern of screwing and transmitted is no more than the border torque.The torque of described border is preferably adjustable, wherein for example at least two level of torque, other level of torque or the step-less adjustment of border torque all are feasible in case of necessity.
In this way, except that hammer drill operation, the operation of brill formula and the operation of pricker cutter, it also is feasible screwing operation, wherein drive motors have high-revolving actuation movement by means of decelerator be converted into be suitable for screwing function, have more slow-revving rotatablely moving, wherein can set the maximum torque that allows by activating torque clutch simultaneously.It is selectable activating torque clutch; Can screw operation or the brill formula is in service does not activate torque clutch in case of necessity, thereby not produce torque limit.
According to preferred embodiment, drive motors, decelerator, beater mechanism and torque clutch in turn and each other are provided with along aligned ground, can guarantee thus to transmit up to the favourable power of instrument storing apparatus by the unit in the middle of being positioned at from drive motors, instrument is arranged in described instrument storing apparatus.
According to first preferred implementation, torque clutch is arranged between beater mechanism and the instrument storing apparatus.According to second preferred implementation, also can consider torque clutch is positioned at beater mechanism and instrument storing apparatus front.Meet the destination, decelerator is located immediately at the outlet side of drive motors and in beater mechanism or torque clutch front in both of these case.
In preferred embodiment, use epicyclic transmission mechanism as decelerator, it advantageously has at least two convertible speed reducing ratio.Epicyclic transmission mechanism or have all and be in operating planetary stage, so that strong rotation actuation movement to the instrument that slows down ground transmission drive motors is used to screw operation, perhaps the gear of epicyclic transmission mechanism is converted into the rotating speed of realizing the operation of brill formula with the actuation movement of drive motors.
In another favourable embodiment, hand held power machine is equipped with batteries, is used for the power supply of the drive motors implemented.Batteries especially is removably disposed on the housing of hand held power machine, and can charging again in charging station when needed.
Perhaps pneumatically or mechanically implement and switching impulse mechanism, can regulate hammer drill operation and the operation of pricker cutter by described beater mechanism.In every kind of situation, the connection of beater mechanism all is selectable.
Description of drawings
Other advantage can draw from other claims, description of drawings and accompanying drawing with the embodiment that meets purpose.Accompanying drawing illustrates
Fig. 1: hand held power machine, be embodied as hammer drill, it is equipped with drive motors and beater mechanism is used for rotatably or hammering ground driven tool, the torque clutch that it also is equipped with decelerator and is used to limit the torque that can transmit, thus hand held power machine can be used as hammer drill, rig, pricker cutter machine and screwdriver.
Fig. 2: the hand held power machine in the embodiment through changing.
In the accompanying drawings, identical parts have identical Reference numeral.
The specific embodiment
At hand held power machine shown in Figure 1 is hammer drill, and it has drive motors 3 in housing 2, and this drive motors is by batteries 4 power supplies of housing bottom.Batteries 4 is constructed to and can dismantles from housing.Can pass through hand switch 5 operation of drive motor.
In order to handle hand held power machine 1 better, can on housing 2, the second in command be set.
In addition, in the housing 2 of hand held power machine 1, be provided with epicyclic transmission mechanism 6, beater mechanism 7 and torque clutch 8.Epicyclic transmission mechanism 6 is located immediately at the outlet side of drive motors 3.Beater mechanism 7 is connected on the epicyclic transmission mechanism 6, realizes hammering function or impact function by described beater mechanism.What be connected with beater mechanism 7 is torque clutch 8.Connect the instrument storing apparatus 9 that is used to hold instrument 10 on torque clutch 8, wherein instrument storing apparatus 9 for example is embodied as the gripping sleeve of drill chuck head or fluting.
