Definitions
- the invention relates to an impact wrench device with a motor that has a Shaft transmits a rotary motion to a screw spindle and one of a cam control sleeve surrounded by an impact mechanism cage for controlling the impact movement drives, where on the head side facing away from the screw spindle
- Cam control sleeve is a web arranged over its circumference, which is in the axial direction has an elevation, whereby the cam control sleeve in interaction with the striking mechanism cage opposite, a channel for the circulation of a ball is arranged and wherein the cam control sleeve in axially displaceable pins engages the one by a sliding movement exerting the striking mechanism compress the spring ensuring the return to the initial state.
- Impact wrenches are used as tools for tightening and Loosening screws. They are in particular to minimize the time and effort required become indispensable in numerous technical fields. Compared to conventional ones pneumatic or electric screwdrivers have impact wrenches the advantage of the fact that, in addition to high torques, they also cause axial strikes are executable. Three types of percussion have prevailed, namely the striking mechanism, the hammer mechanism and the claw mechanism.
- the object of the invention is therefore to create a screwdriver device, that prevents the creation of uncontrolled high torques and is gentle on the material is by overtightening the screws and related destruction excludes.
- the device should be significantly more reliable and safe than previously possible work and prevent unnecessary noise pollution. With the new device to Loosening screws significantly higher torques can be applied than to their tightening.
- cam control sleeve during the tightening movement the screw allows the ball to lock and thus allows it to rotate the striking mechanism is designed to block and in the releasing movement the screw allows the ball to run around on the track or in the channel and thus producing the striking mechanism while rotating is trained.
- the impact wrench device thus offers the advantage that the striking mechanism is blocked when the screw is tightened, i.e. when turning clockwise and only the rotating mechanism works.
- the impact wrench device brings only a predetermined torque. This is usually less than that Torque with which the screw is ultimately to be fastened.
- Torque with which the screw is ultimately to be fastened.
- the remaining torque is from the operator mechanically, for example by using an appropriate torque wrench to apply. This will damage and destroy the Avoid rim or the screws.
- cam control sleeve the impact mechanism of the screwdriver.
- both rotating and striking mechanisms work.
- the power transmission between cam control sleeve and striking mechanism cage works as with conventional impact wrench devices without any disadvantages compared to that prior art known to date.
- the single-running turning mechanism when tightening and combined turning / striking mechanism when the screw is loosened that the cam control sleeve has at least one elevation on its head side, causing the web to rise flat and even on one side and the other Side abruptly falling and thus interrupting the course of the path, whereby the contact between ball and track is brief, with the striking mechanism accompanying, interrupted. Because of this fundamentally different training The path on both sides of the elevation is thus reached that the ball blocked when tightening the screw, d. H. jammed, and when loosening the screw is moved over a flank which ensures constant running of the ball.
- This arrangement of the track causes the impact wrench to run counterclockwise the cam control sleeve strikes in the direction of the screw spindle and thus the desired striking movement generated.
- the invention provides that the bulge in terms of shape the ball corresponds.
- the bulge in terms of shape the ball corresponds.
- an undesirable soaring of the ball the elevation when tightening the screw is avoided and the ball really is jammed and secondly that the ball has no play, which is unnecessary Unbalance and thus wear.
- this rounding adapted to the sphere offers a permanent and tried and tested Safety.
- Optimal circulation of the ball is further achieved by the fact that in the Bottom of the striking mechanism cage at least one channel with the cam control sleeve for the ball resulting circular groove is provided, which in interaction with the cam control sleeve is designed to enable the ball to lock.
- This groove is located in the part of the striking mechanism cage facing the cam control sleeve.
- a relief valve is assigned to the supply air duct of the impact wrench device.
- This Relief valve opens in the event of excessive pressure and lets the air into the exhaust air duct flow. In this way, the air supplied to the engine is controlled or limited.
- a maximum torque can be set using a suitable adjusting device be selected. This leads to the fact that with a pure rotating mechanism of the Impact wrench only tightened the screws to a specified seat which provides an optimal level of control over the tightening of the screws can be realized without the risk of destruction.
- the Operators using a suitable key the final tight fit of the Adjust screw. Tightening the screws is therefore impossible.
- a preferred embodiment of the invention provides that the longitudinal axis and thus the thrust axis of the impact wrench device parallel and below the drive axis the pneumatic motor arranged in the handle of the impact wrench device is.
- This parallel arrangement of the two axes has the advantage that one Inadvertent switching on or off of the impact wrench device almost impossible can be. So the device can not be stored in a way that a button is inadvertently adjusted because it is used to switch the device on and off relevant buttons and adjustment devices in protected places or such Places where the device cannot be placed. Most of all it proves In the embodiment according to the invention, however, it is advantageous that the device is used with one hand can be operated because the switches are also operated with a conventional handle can be.
- the invention is particularly characterized in that an impact wrench device is created in which the two functions of a rotating mechanism and one Combined turning / striking mechanism are realized.
- an impact wrench device is created in which the two functions of a rotating mechanism and one Combined turning / striking mechanism are realized.
- the device according to the invention acts like a screwdriver when loosening the screw like an impact wrench. This marks significant progress in terms of protecting the material and occupational safety achieved.
- Fig. 1 shows an impact wrench device 1, consisting of the housing 30 and the handle 24.
- this housing 30 is the pneumatic motor, not described in detail housed, which drives the shaft 4.
- the size of the respective screw not shown here Nut that grips this and the torque of impact wrench 1 on transmits the screw, also not shown here. 1 is the parallel one Arrangement of the drive shaft 22 to the reversing shaft 23 can be seen.
- the Reversing shaft 23 the corresponding direction of rotation, counterclockwise or clockwise rotation is selected and set.
- the operator can, for example with the thumb, not shown here, on the back of the impact wrench Operate 1 attached buttons.
- the impact screwdriver 1 shown here is initially connected to the air connection connected to the compressed air network. By pressing the operating lever 33 the valve stem 34 moves the valve ball 35 back so that the air enters the supply air duct 28 can reach.
- the relief valve 21 is arranged above the supply air duct 28 and connected to it via the opening 36.
- the valve spool 20 closes by the bias of the spring 38, the through hole between the opening 36 and Exhaust air opening 37.
- the spring 38 can be adjusted via an adjusting device 40.
- the torque to be applied by the impact wrench device 1 is predetermined, by checking the amount of air supplied to the engine. If the pressure in the Supply air duct 28 is higher than the value which the spring 38 receives with its pretension can, the relief valve 21 opens and allows the air through the exhaust port 37 flow into the exhaust air duct 29.
- FIG. 3 shows the ball 10, which in the channel 9 formed by percussion cage 6, shaft 4 and track 3 runs all around.
- the ball 10 is in a position in which it blocks the striking movement.
- Ball 10 is to one side of cam control sleeve 2 and the other Side of the striking mechanism cage 6 included. This is made possible by the groove 19, which is arranged in the bottom 11 of the striking mechanism cage 6 and a movement of the Ball 10 over the edge of the groove 19 prevented.
- Fig. 5 shows an illustration of the cam control sleeve 2, on which the web 3 in particular is easy to see.
- the collar 26 is provided for the suitable transmission of the axial forces.
- the ball 10 When tightening the screw clockwise, the ball 10 is in the bulge 16 of the survey 8. Because the ball 10 is on the inside of the channel 9 by the shaft 4 and on the outside by the striking mechanism cage 6, and on the Head side 7 of the cam control sleeve 2 also held by the striking mechanism cage 6 she cannot leave her position. Ball 10 rotates with the cam control sleeve 2 with, simultaneous axial displacement is excluded.
- the bulge 16 is advantageously designed such that the ball 10 is as possible owns no game.
