Definitions
- the invention relates to a motor-driven hand screwdriver.
- Such screwdrivers are used, for example, in the automotive sector, in particular in the manufacturing plants, but also in repair shops.
- hand-held devices are referred to as handheld screwdrivers, even if they are
- Devices are motor-driven. In the following, these devices are referred to as stick screwdrivers if they have a rod-shaped housing, and they are referred to as pistol screwdrivers if their housing is angled.
- the drive is usually electrical or compressed air.
- the motors are usually supplied with electrical energy centrally via a connecting cable or decentrally by means of a separate accumulator, but screwdrivers with a different form of power supply are also conceivable, for example by means of a battery, capacitor or other electrical energy store.
- such a screwdriver Starting from a possibly existing pneumatic or electrical power connection, such a screwdriver then has an actuating handle, then one Motor and then a gear, usually designed as a planetary gear, and then a clutch, to which the free end portion of the screwdriver, which is referred to as the "head", is attached, whereby this head can be designed in a straight line or - in particular in the case of straight screwdrivers - as an angular head.
- stick screwdrivers provided with angle heads are often no longer referred to as stick screwdrivers, but are then referred to as "angle screwdrivers".
- angle head refers to a head whose drive shaft is angled relative to its output shaft, often at an angle of 90 ° Free end of the head, the output shaft is usually designed as a square, on which, for example, sockets with the wrench size desired for the screw connection can be attached.
- Safety-relevant screw connections e.g. B. in the area of the steering or the brake system, are usually carried out with a two-stage tightening: First, a fast as possible screwing to about 80 or 90% of the target
- the first, quick tightening in such a two-stage screw connection is usually done by means of a motor using the hand-held screwdriver mentioned.
- the end of this first motor tightening of the screw is achieved by a torque limiter, which is either implemented directly in the handheld screwdriver, or in the case of pneumatic so-called "stall screws", the maximum torque to be applied can be limited by the air pressure with which the tool is driven, so that here the torque limiter assigned to the drive motor is implemented outside the actual tool.
- Torque wrench has the required accuracy, so that within the specified tolerances the torque wrench triggers exactly at the previously set nominal torque, for example by means of a kink mechanism, so that a clearly audible click and a certain
- Torque wrenches that are adjustable or that trigger at a factory-specified torque are known from practice.
- DE AS 21, 06.263 also shows a torque wrench designed as an articulated wrench.
- a motor-driven, hand-held screwdriver is known from US Pat. No. 4,060,137, which has means for limiting the torque and possibly for automatically switching off the screwdriver when a preset torque is reached.
- This screwdriver is based in principle on the design of a pistol screwdriver, but the components known from a pistol screwdriver almost only make up the grip area of an overall considerably larger, approximately iron-shaped, large housing.
- This screwdriver does not have a freely ending “head” in the aforementioned sense; rather, gear means connect to the drive unit, which in turn lead to the handle and the connection provided there for a compressed air supply.
- the screwdriver is not intended to be operated without a motor drive.
- the triggering accuracy of the pneumatic torque limiter may not be sufficient for some safety-related screw connections.
- Torque wrench known from the Tohnichi company, on which a pneumatic motor is mounted and which the manufacturer or distributor of these tools consequently calls a torque wrench ("Torque wrench with air motor”) rather than a motorized hand wrench.
- Torque wrench enables First a motorized tightening of the screw connection, after which the otherwise unchanged torque wrench is used in the manner known per se.
- the invention has for its object to provide a motor-driven handheld screwdriver, which promotes quick work and quick completion of a screw connection, even with a two-stage tightening.
- the invention proposes to combine the motor drive usually provided in the handheld screwdriver with an additional ratchet drive with its own torque limiter, as is provided with torque wrenches.
- ratchet drive refers to any drive that enables the transmission of a tightening torque in one direction of rotation and that runs freely in the opposite direction of rotation, for example a ring gear with a locking device that allows locking or guiding in one Direction allows, whereby in technology such a ratchet drive is often referred to as a freewheel.
- the screw can be fixed by the motor-driven handheld screwdriver until its torque limiter triggers, and now, without the handheld screwdriver being required, subsequently with this handheld screwdriver the correct torque can be checked or achieved, namely that the handle of the screwdriver now serves as a handle for the torque wrench and the two work processes "tightening the screw” and "Control of the screw” can be carried out by one person in one pass without changing tools, ie the torque wrench is not actuated by the motor drive, but by purely manual actuation of the screwdriver until the second torque limiter arranged in the head and assigned to the ratchet drive trips.
- the two torque limiters on the one hand for motorized use and on the other hand for manual use of the handheld screwdriver, are typically set to different values, so that, without having to make any adjustments or changes to the handheld screwdriver, screwed connections with two different achievable torques and, accordingly, screwed connections tightened in two stages possible are.
- torque limiter the additional torque limiter provided in the head of the handheld screwdriver is always meant, while the first torque limiter assigned to the motor drive of the handheld screwdriver is regarded as an integral, already existing component of the handheld screwdriver as an external device, such as the air pressure supplied to a pneumatic wrench.
- the torque wrench which the manually operated handheld screwdriver forms, can be designed in a manner known per se as a kink wrench or as a bending beam, mechanical control being carried out when the torque wrench is designed as a kink wrench, while an electronic one is used when the torque wrench is designed as a bending beam
- Control can be provided.
- the nominal or nominal torque at which the torque limiter trips is usually higher than the cut-off torque of the motor-driven screwdriver.
- the screwdriver triggers switches provided in any case at a predetermined torque, which can correspond to approximately 80 or 90% of the target torque.
- a predetermined torque which can correspond to approximately 80 or 90% of the target torque.
- this can be done by a sensor that triggers the motor to be switched off.
- the screwdriver can be used as a torque wrench, not as a motor, but as a hand-operated screwdriver, until the torque limiter trips at 100% of the preset target tightening torque as part of this second tightening or tightening step, which is not set on the actual handheld screwdriver, but on the torque limiter.
- This setting can be predefined by the manufacturer and thus tamper-proof, but it can advantageously be provided by the user, so that the hand screwdriver can be easily adapted to different screwing conditions.
- the torque limiter and the ratchet drive are arranged together in the head of the screwdriver.

- an adapter can advantageously be provided which, on the one hand, connects to a standardized drive shaft of the head and, on the other hand, has a connection adapted to its output shaft, depending on the base body of the screwdriver used. In this way, inexpensive manufacture of the embodiments according to the invention is possible
- the drive shaft of the head is already designed for connection to a specific type of output shaft even without an adapter, so that the screwdrivers designed with such an output shaft can be provided with the head designed according to the invention without using an adapter .
- the torque limiter can advantageously be designed as a buckling element in a manner known per se, so that the kinking indicates to the user that the predetermined target torque has been reached and the handling of the
- Screwdriver - except for the relief mentioned - can be done in the way known to the user without getting used to.
- the swivel-mounted holder is swivel-mounted in the area of the tool shank.
- the regarding the transferable torque too limiting axis is located away from this storage.
- a lever arm between these two swivel or rotary axes is advantageously avoided in the proposed handheld screwdriver, in that the articulated element is mounted in such a way that the swiveling holder which is present in such articulated elements and which tensions the actual articulated body against a second holder , is pivotally mounted about the axis, which at the same time also represents the axis whose transmissible torque is to be limited.
- An optical display can advantageously be provided, which is triggered when the predetermined target tightening torque is reached. It can be provided in a particularly simple, reliable and inexpensive manner to trigger the display mechanically, for example by changing the color behind a viewing window on the screwdriver or by means of an axially movable pin, a swivel-mounted bolt or the like.
- an electrical signal transmitter can be provided which generates a signal when the predetermined target tightening torque is reached.
- These signals can be wired or wireless, e.g. B. by radio, for example to a remote control remote from the hand-held screwdriver, which can register the number of screw connections carried out and / or the strength of the tightening torques, at least the achievement of a predetermined target torque.
- Such signals of the electronic signal transmitter can, however, also be evaluated on the handheld screwdriver itself an electronic circuit which triggers an acoustic or optical signaling by electrical means, for example by an indicator lamp or by a high-frequency signal tone, for example when the predetermined tightening torque is reached.
- the electrical signals of the signal generator can also be evaluated by the electrical circuit in order to trigger the optical and / or acoustic display mentioned after a predefined number of correctly carried out screw connections.
- the worker can be provided with a functional control of his work. For example, when screwing wheels with five screws, the can be done after five correct screw connections have been made
- the mechanical or electrical, optical or acoustic display can advantageously be provided on the head of the hand screwdriver. This means that it is not only optimally arranged in the field of vision or hearing of the worker, but in this way the embodiment of the invention can also be particularly advantageous
- Head have all the advantageous functions and display options, so that a particularly simple retrofitting of existing handheld screwdrivers is possible or a particularly simple repair of handheld screwdrivers is made possible by the head having all functions can be completely replaced.
- the handheld screwdriver is designed as a rod screwdriver with an elongated housing, in contrast to the pistol screwdrivers mentioned above, handling the handheld screwdriver is simplified with manual operation, since it is similar to standard, also rod-shaped torque wrench is designed and accordingly enables familiar handling.
- Angle head is provided, a simple and efficient handling of the screwdriver is possible both as a motorized screwdriver and then as a torque wrench, with as little effort as possible for the user, whereby the user can maintain his hand position on the screwdriver, i.e. without moving the handheld screwdriver or otherwise handling it have to.
- cordless screwdrivers are used in particular for screwing inside the vehicle. For example, they are designed to transmit torques up to a maximum of 15 Nm.
- the housing is designed to be lightweight, usually made of plastic, in order to make it easier to handle.
- the housing of the proposed hand screwdriver can advantageously be designed to be considerably more resistant to bending than the known housings, since the housing not only has a protective function for the motor drive units. unit of the hand screwdriver, but because the housing has to withstand the forces to be transmitted manually.
- the handle of the handheld screwdriver is advantageously designed not only to actuate the drive motor, for example provided with a trigger switch for the motor, but is also designed as a grip area in such a way that the entire handheld screwdriver can be handled like a purely hand-operated screwdriver.
- the particularly flexurally rigid housing enables the transmission of high tightening torques that would destroy conventional motorized handheld screwdrivers, for example twice or even more than 10 times the torque to be applied by the motor.
- This design of a cordless handheld screwdriver allows tightening torques of 40, 50, 100 or even more than 150 Nm to be possible compared to the conventional 15 Nm.
- the housing can be made of plastic, in particular of a fiber-reinforced plastic, if the desired bending strength of the housing is guaranteed.
- the housing can preferably be made of metal, in this case preferably made of light metal in favor of fatigue-free handling.
- Fig. 1 shows a section through the head area of a
- the head of a hand screwdriver is generally indicated by 1.
- the head 1 is designed as an angular head and on a rod-shaped housing of a so-called Fixed screwdriver, whereby the housing consists of a light metal alloy, which enables a high bending strength of the housing.
- the stick screwdriver contains a complete drive unit with an energy store or a connection for a power supply, a drive motor, an actuation switch for the drive motor and with a built-in torque limiter which limits the torque which can be transmitted from the motor to the output shaft of the drive unit in a manner known per se, e.g. B. in an electric motor by switching off the motor, in a compressed air motor by partial or full bypass of the drive air or in a similar manner.
- Stick screwdrivers are known per se, so that for reasons of clarity only the end of a shaft 2 of this stick screwdriver can be seen in the drawing.
- the head 1 has a housing 3 in which an angular arrangement known per se is provided for deflecting the force.
- An output shaft 4 is provided on the head 1, which is designed with its free end as a square and serves to receive sockets.
- the output shaft 4 is extended to the rear, whereby it can be configured in one or more parts. It extends from the actual housing 3 of the head 1 and extends into a torque limiter 5, which can be seen in particular in FIG. 2.
- This is designed in the same way as a basically known torque wrench as a so-called kink wrench. It has a ratchet drive 6 with a changeover switch 7 for the selection of the torque-transmitting working direction, and it has an articulated joint 8, the articulation of which
- Body 9 is clamped between a first bracket loaded by an indicated spring 10 and a second bracket 15.
- the spring 10 can be relaxed or tensioned with the aid of an adjusting screw 11, so that the pretension for the articulated joint 8 can be adjusted and thus the torque at which the articulated joint 8 is bent.
- the bracket 15 is pivotally mounted about a pivot axis which coincides with the axis of the output shaft 8. Through the pivoting movement of this bracket 15, the kink body 9 can perform the kinking movement. The fact that the pivot axis of the bracket 15 with the transmitted in
- Torque limited output shaft 4 coincides, a lever arm between a pivot axis of the bracket 15 and this torque limited shaft is avoided.
- Torque limiter 5 can be influenced by touching the handheld screwdriver at different points on its shaft and by the user possibly applying a lever force between the palm of the hand and the thumb and thus introducing a moment into the handheld screwdriver which acts as a transverse force on the lever. that arises between the mounting of the articulated bracket and the torque-limited shaft. Such influences are excluded in the handheld screwdriver shown, so that the switch-off torque of the
- Torque limiter 5 is maintained reliably and with high uniformity, so that overall very precise screw connections can be achieved.
- the torque-limited shaft is also the output shaft 4 of the handheld screwdriver.
- the positive effects described remain:
- the screw axis would not coincide with the pivot axis of the holder 15 as in the exemplary embodiment shown. Nevertheless, the torque-limited axis, namely an output shaft, which serves as a drive shaft for the flat output, together with this pivot axis of the bracket 15, so that the advantages described are retained.
- the housing 3 can surround the torque limiter 5, so that only the set screw 6 and an actuating handle for the changeover switch 7 are visible to the user outside the housing 3.
- the head 1 is fastened to the shaft 2 by means of an adapter 12: the adapter 12 has a housing 14 which on the one hand has connection means for the output shaft of the straight screwdriver and on the other hand has connection means for the drive shaft of the head 1.
- the head 1 can be used on different types of hand screwdrivers, and conversely, by using corresponding adapters, a large number of differently designed heads can be used on the shank 2 shown.
