Description

[0001] The invention relates to a device for transmitting an impact movement of an impact element in a first impact direction to a tool which is movable in at least one second impact direction deviating from the first, wherein the transmission of the impact movement takes place by means of a movably mounted impact force deflecting element, wherein the impact force deflecting element has two stop surfaces, wherein one stop surface is assigned to the impact element and the other stop surface is assigned to the tool, wherein the tool plunger is movable in the second impact direction counter to the action of an elastic element, according to patent claim 1. Furthermore, the invention relates to an impact tool with a device for transmitting an impact movement of an impact element, according to patent claim 11.

[0002] Tools, particularly impact tools, have been known for some time that machine the surface of a metal workpiece by applying impact pulses as part of a cold forging process. Reference is made to DE 10 2012 103 111 A1 as an example in this context.

[0003] In the prior art, the direction of movement of the impact element of an impact tool extends parallel to the longitudinal extent of the impact tool, so that when the impact tool is clamped at an angle of approximately 90° to the surface to be machined, inclined surfaces in between can only be machined inadequately, since they are then only subjected to an impact force component corresponding to the angle of the inclined surface.

[0004] DE 40 39 779 A1 discloses an angle attachment for mounting on a handheld power tool, such as a hammer drill or impact drill. This angle attachment comprises a rocker arm, by means of which a first impact force of a striking element is transmitted to two tools, wherein the two tools are movable in at least one second impact direction that differs from the first.

[0005] The document US 2 880 715 A describes an attachment for a percussion hammer which redirects the striking movement of a striking element in a first striking direction onto a tool, wherein the striking direction of the tool deviates from the first striking direction.

[0006] A hammer element or impact force deflection element acts directly on the tool.

[0007] EP 0 035 097 A1 shows a device for surface treatment with an impact force deflection element by means of which the impact direction of the firing pin is deflected, so that an impact direction of the tool deviates from the impact direction of the firing pin.

[0008] Furthermore, DE 10 2009 025 621 A1 describes a method for producing a metallic component with a hardened surface layer, wherein the surface layer is hardened by tapping or hammering using a striking head.

[0009] The invention is based on the object of providing a correspondingly further developed device, or rather, a correspondingly further developed impact tool. This object is achieved by a device according to claim 1.

[0010] In particular, the object is achieved by such a device for transmitting an impact movement of an impact element in a first impact direction to a tool which is movable in at least one second impact direction deviating from the first, wherein the transmission of the impact movement takes place by means of a movably, in particular rotatably mounted impact force deflecting element, wherein the tool plunger comprises a piston section which is mounted axially displaceably within a device housing and into which the impact force deflecting element engages, wherein the piston section has a lateral recess into which the impact force deflecting element is inserted such that the stop surface of the impact force deflecting element assigned to the tool or tool plunger interacts with the boundary surface of the lateral recess facing the tool plunger.

[0011] Accordingly, the device comprises at least one tool and a movably, in particular rotatably, mounted impact force deflection element. The impact movement of an impact element of an impact tool is transmitted to the tool from a first impact direction to at least one second impact direction that differs from the first by means of the impact force deflection element.

[0012] The impact force deflection element has two stop surfaces, one of which is assigned to the impact element and the other to the tool. In other words, the impact force or impact movement of the impact element is transferred to the first stop surface of the impact force deflection element. The impact force or impact movement is transferred to the tool via the second stop surface of the impact force deflection element.

[0013] The tool ram is movable in the impact direction against the action of an elastic element. The impact direction of the tool ram is the second impact direction of the device.

[0014] The axially displaceably mounted ram of the tool, which is referred to below as the tool ram, comprises a piston section which is axially displaceably mounted within a device housing, wherein the impact force deflection element engages in the piston section. The device housing in which the piston section of the tool ram is mounted can, for example, be designed as a hollow cylindrical section or as a hollow cylinder. For example, the longitudinal axis of this hollow cylindrical section coincides with the second impact direction or the second impact direction lies on the longitudinal axis of the hollow cylindrical section. The longitudinal axis of the hollow cylindrical section or of the device housing can therefore specify the design or arrangement of the second impact direction. The device housing or the device housing section which has a hollow cylinder orcomprises a hollow cylindrical section, can have a wall, preferably a cylindrical wall, for example a circular cylindrical, prism-shaped, or cuboid-shaped wall, wherein the wall preferably defines a circular cylindrical recess in the interior of the section or cylinder. The piston section of the tool ram is mounted for axial displacement in this hollow cylindrical section or the device housing.

[0015] The impact force deflection element engages the piston section. For this purpose, the piston section has a lateral recess into which the impact force deflection element engages such that the stop surface of the impact force deflection element associated with the tool or tool ram interacts with the boundary surface of the lateral recess facing the tool ram. The piston section of the tool ram serves to axially support and guide the tool ram in the fixture housing or in the hollow cylindrical section.

[0016] A significant advantage of such a device for transmitting a striking motion is that this device can be mounted, for example, on known striking tools, and the striking motion of the striking element of a known striking tool can be redirected by the device for transmitting a striking motion according to the invention. With the aid of such a device, it is now possible to perform surface machining, in particular cold forging, even on inclined and / or angled surfaces in such a way that the striking element also acts on these surfaces essentially at a 90° angle. This advantage is particularly evident when inclined machining surfaces are difficult to access.

[0017] The familiar, rod-shaped impact tools should always be held at an angle of approximately 90° to the surface being worked on, as the impact element acts in the direction of the rod-like impact tool. When working on an inclined surface, the impact tool must be held at an appropriate angle so that the impact element can act on the surface to be worked on at an angle of approximately 90°.

[0018] If the inclined surface in question is difficult to access, the impact tool cannot be optimally aligned to the surface to be machined. This is where the invention comes in with the device for transmitting an impact movement, which also allows the machining of difficult-to-access inclined surfaces at an angle of approximately 90°, since the impact force and its direction can be deflected to adapt to diagonally extending machining surfaces. The first impact direction is the axis of movement or the impact movement axis of the impact element of a generally conventional rod-like impact tool. This first impact direction can be deflected with the aid of the device for transmitting an impact movement of an impact element by an angle that can have a value of greater than 0° to 90°. The first and at least the second impact direction, which deviates from the first impact direction, enclose an angle or deflection angle of greater than 0° to 90°, in particular approximately 60°.The deflection angle therefore describes the angle of at least the second impact direction that deviates from the first impact direction.

[0019] The tool can comprise an axially displaceably mounted ram, namely a tool ram, at whose distal end facing away from the deflection element or distal end a curved, in particular spherically curved, surface treatment means is arranged or formed. With the aid of the tool, a surface to be treated is subjected to a deflected impact force. The tool can therefore have a distal end, which corresponds, for example, to the end facing away from the impact force deflection element, with a surface treatment means arranged or formed at this or the distal end. The surface treatment means has, for example, a curved, in particular spherically curved shape.

[0020] The surface treatment means can be arranged at the distal end of the tool or the ram, in which case the surface treatment means is a separate component. Furthermore, it is conceivable for the surface treatment means to be formed integrally with the axially displaceably mounted tool ram, so that the surface treatment means is formed at the distal end of the displaceably mounted tool ram.

[0021] In a further embodiment of the invention, it is possible for a ball, hemisphere, or spherical segment to be formed and / or attached to the tool, in particular to an axially displaceably mounted tool ram, in particular at the distal end thereof. The ball, hemisphere, or spherical segment is preferably made of a hard metal, so that an incremental cold forging process can be carried out with the aid of the ball, hemisphere, or spherical segment. In this process, the surface treatment agent, in particular the ball / hemisphere or spherical segment, is tapped onto a metallic workpiece surface, preferably at a frequency of more than 100 Hertz. Due to the tapping of the surface, it is smoothed. In addition, residual compressive stresses are introduced into the edge layer of a workpiece to be machined in combination with work hardening.Tapping makes subsequent hardening of a workpiece surface unnecessary.

[0022] The stop surfaces of the impact force deflection element can extend at an angle to each other, in particular at an angle corresponding to the deflection angle.

[0023] The impact force deflection element can comprise a fastening section and a stop surface section. For example, a recess for receiving a fastening means can be formed on the fastening section, around whose longitudinal axis the impact force deflection element is movably mounted.

[0024] The fastening section is, for example, shaped like a circular segment and includes the recess, which is preferably a bore. A fastening means can be inserted into the recess or bore. The fastening means serves to lock the impact force deflection element to a housing section of the device for transmitting a striking movement of a striking element. For example, the fastening means is designed as a cylindrical pin. The impact force deflection element is movably mounted or locked around the longitudinal axis of the fastening means or the cylindrical pin.

[0025] The fastening section of the impact force deflection element preferably merges into a stop surface section. This stop surface section can, for example, be shaped like a circular segment. The fastening section and the stop surface section can be monolithic or formed as a single piece. The stop surface section is delimited by the aforementioned stop surfaces, wherein the stop surfaces enclose an angle with the longitudinal axis of the fastening means that approximately corresponds to the deflection angle of the device according to the invention. The impact force deflection element therefore has, for example, the shape of a rounded projection. Furthermore, the impact force deflection element can also be referred to as a cam element and / or cam-shaped element.

[0026] The impact force deflection element engages the piston section. For this purpose, the piston section has a lateral recess, particularly in the form of a longitudinal slot, into which the impact force deflection element engages. The stop surface of the impact force deflection element associated with the tool or tool ram interacts with the boundary surface of the lateral recess or longitudinal slot facing the tool ram. The piston section of the tool ram serves to axially support and guide the tool ram in the device housing or in the hollow cylindrical section.

[0027] The tool ram is movable in the impact direction against the action of the elastic element, in particular a spring. The impact direction of the tool ram is the second impact direction of the device. A compression spring is preferably provided so that the tool ram is mounted in the device housing or the hollow cylinder or hollow-cylindrical section of the device according to the invention, preloaded against its impact direction.

[0028] The tool ram can, for example, comprise a rod-like section, which preferably has a rotationally symmetrical cross-section, and a ram element arranged at the proximal end, in particular molded onto it, in the form of a transverse web.

[0029] The aforementioned elastic element is preferably arranged around the (rotationally symmetrical) rod-like section, which is clamped between the crosspiece and a distal collar of the device housing, in particular the hollow cylindrical section. The collar is preferably rotationally symmetrical and has an inner diameter that is slightly larger than the outer diameter of the (rotationally symmetrical) rod-like section of the tool ram.

[0030] When the tool ram moves toward the collar of the fixture housing, the compression spring located between them is compressed. As soon as the force is no longer exerted on the crossbar of the tool ram, the compression spring moves the tool ram back to its original position.

[0031] The device may have a connecting section on the side facing the striking member, i.e. a section for connection to a striking tool comprising the striking member.

[0032] The connecting section can, for example, have a thread complementary to a thread of the impact tool and / or a locking section complementary to a locking section of the impact tool. The connecting section can, for example, comprise a recess that serves to precisely guide the longitudinally movably mounted impact element of an impact tool. The impact element is accordingly a structural element of the impact tool, wherein the impact element is, for example, mounted for longitudinal movement in a recess of the connecting section of the device according to the invention when connected. In other words, the impact element of an impact tool is inserted into the device according to the invention, in particular into a recess of the connecting section of the device, and mounted there for longitudinal movement.

[0033] With the aid of the aforementioned threads inserted into or attached to the connecting section, the device according to the invention can be screw-connected to an impact tool in a simple manner.

[0034] Furthermore, or alternatively, it can be provided that the connecting portion has a locking portion complementary to a locking portion of the impact tool. Accordingly, it is possible to lock the device according to the invention to an impact tool. The device according to the invention can therefore be designed such that it can be screwed and / or snapped onto an impact tool.

[0035] Furthermore, a maintenance and / or assembly opening can be formed on the side of the device housing opposite the collar, so that the device according to the invention, in particular the tool or tool ram, can be replaced and / or installed. To prevent contamination of the interior of the device housing, a corresponding closure or cover is provided. The closure is preferably screwed into or onto the maintenance and / or assembly opening.

[0036] In a further embodiment of the invention, the device according to the invention for transmitting a striking movement of a striking member can comprise two striking force deflecting elements, one of which is associated with a first tool acting in a first predetermined direction and one of which is associated with a second tool acting in a second predetermined direction.

[0037] In other words, the impact force or impact movement of a striking element can be transmitted in two impact directions that differ from the first direction. For this purpose, an impact force deflection element and a tool are provided for a first predetermined direction, and an impact force deflection element and a tool are provided for a second predetermined direction.

[0038] In this case, the first and second tools can act symmetrically to the first impact direction of the impact element of an impact tool or can be arranged symmetrically to the first impact direction of the impact element. The tools can comprise axially displaceably mounted plungers. However, the tool plungers preferably do not comprise an axially displaceably mounted piston section. The two impact force deflecting elements are preferably shaped such that, at maximum possible contact between the two impact force deflecting elements, they delimit a recess into which the impact element of an impact tool can penetrate, thus enabling the transmission of the impact movement of the impact element from a first impact direction both into a first predetermined direction and into a second predetermined direction simultaneously.

[0039] The tools or the tool rams can have curved or spherically curved surface treatment means at the ends facing away from the deflection elements or at the distal ends, wherein these surface treatment means can be arranged or formed at the distal ends of the tool rams.

[0040] With the aid of a device according to the invention, which has two impact force deflection elements and two tools, the simultaneous machining of multiple workpiece surfaces is possible. For example, the machining of two inclined surfaces is possible, whereby both inclined surfaces can be machined at an angle of approximately 90° using the device according to the invention, since the impact force and its direction can be deflected in two predetermined directions to adapt to the inclined machining surfaces.

[0041] The device according to the invention for transmitting a percussion movement of a percussion element can be combined with a variety of embodiments of known percussion tools. In this context, a connection to both pneumatically operated percussion tools and percussion tools operated with the aid of a cooling and / or lubricant circuit of a machine tool is possible. In this regard, particular reference is made to DE 10 2012 103 111 A1, the disclosure of which is expressly incorporated herein by reference.

[0042] The object with regard to a further developed impact tool is achieved with an impact tool according to patent claim 13. The impact tool according to the invention has a device for transmitting an impact movement of a striking element or comprises a device for transmitting an impact movement of a striking element, wherein the impact tool can be connected to a robot arm in a predetermined manner.

[0043] Further advantageous developments of the inventive concept and embodiments of the invention are set forth in the dependent claims. The invention is described below using exemplary embodiments, which are explained in more detail with reference to the accompanying drawings.

[0044] Here we show: Fig. 1 a schematic representation of an embodiment of a device according to the invention for transmitting a striking movement of a striking organ; Fig. 2 shows a representation of the device according to the invention in a state mounted on a striking tool; and Fig. 3 a schematic representation of a further embodiment of a device according to the invention for transmitting a striking movement of a striking organ.

[0045] In the following description, the same reference numbers are used for identical and equivalent parts.

[0046] Fig. 1 shows a longitudinal section through an embodiment of the present invention.

[0047] The device 10 according to the invention according to this embodiment of the present invention serves to transmit an impact movement of an impact element in a first impact direction B1 to a tool 20 which is movable in at least one second impact direction B2 deviating from the first, wherein the transmission of the impact movement takes place by means of a movable, in particular rotatably mounted, impact force deflection element 30.

[0048] In the embodiment according to Fig. 1, the striking element is not shown. However, the first striking direction B1 of the striking element is shown, with the first striking direction B1 and the second striking direction B2 being arranged at a deflection angle α to each other. The deflection angle α can have a value from greater than 0° to 90°. In the illustrated embodiment, the value of the deflection angle α is 60°.

[0049] The device 10 comprises a device housing 11 and a connecting section 12 with a recess 13 for guiding the striking element 60, not shown, which is mounted for longitudinal movement.

[0050] The tool 20 comprises according to Fig. 1 an axially displaceably mounted tool ram 21, at the distal end 22 of which is remote from the impact force deflection element 30, a curved, namely spherically curved, surface treatment means 23 is arranged. The surface treatment means 23 is preferably made of hard metal and is attached to the distal end of a rod-like section 24 of the tool ram 21. With the help of the hard metal surface treatment means 23, for example, cold forging in the sense of surface smoothing can be carried out. In this context, the surface treatment means 23 can be subjected to a frequency of more than 100 Hertz, so that the surface of a metallic workpiece is smoothed by tapping.

[0051] The tool ram 21 is mounted for axial displacement within a section of the device housing 11. For this purpose, the device housing 11 has a hollow cylindrical section 25, or a hollow cylinder for short, with the longitudinal axis L of the hollow cylinder 25 corresponding to the second impact direction B2. The tool ram 21 is mounted for axial displacement within the hollow cylindrical section 25.

[0052] The impact movement of the impact element is transmitted to the tool 20, in particular to the tool ram 21, by means of the impact force deflection element 30. The longitudinal axis l of the recess 13 corresponds to the first impact direction B1 of the impact element 60. Accordingly, the impact movement emanating from an impact element 60 can be transmitted to the tool 20 with the aid of the impact force deflection element 30, so that the impact movement is deflected from the first impact direction B1 to the second impact direction B2.

[0053] The impact force deflection element 30 has two stop surfaces 31, 32, one stop surface 31 being assigned to the impact element 60 and the other stop surface 32 being assigned to the tool 20. The stop surfaces 31 and 32 of the impact force deflection element 30 extend at an angle to one another, in particular at an angle corresponding to the deflection angle α.

[0054] The impact force deflection element 30 has a fastening section 33 and a stop surface section 34. A bore 35 for receiving a fastening means 36 is formed on the fastening section 33. The fastening means 36 is designed as a cylindrical pin. The impact force deflection element 30 is movably mounted about the longitudinal axis of the fastening means 36 or the cylindrical pin. The stop surface section 34 is delimited by the two stop surfaces 31 and 32, wherein the stop surfaces 31 and 32 approximately enclose the deflection angle α in relation to the longitudinal axis of the fastening means 36. The fastening section 33 and the stop surface section 34 are formed integrally or monolithically.

[0055] The impact element acts on the stop surface 31 or the impact element touches the stop surface 31, so that the impact movement is transferred from the stop surface 31 of the impact force deflection element 30 to the stop surface 32. The stop surface 32 acts on the tool ram 21 or the cross member 26 of the tool ram 21.

[0056] The tool ram 21 comprises a piston portion 27 mounted axially displaceably within the device housing 11, which serves to axially support and guide the tool 20 or the tool ram 21. In other words, the piston portion 27 is a guide portion of the tool ram 21, which is designed in the form of a piston and is longitudinally guided in the device housing 11, namely in the hollow cylindrical portion 25.

[0057] The cross member 26 arranged on the rod-like section 24 of the tool ram 21 is formed as an integral element of the piston section 27. This means that the distal end face of the piston section 27 defines the cross member 26. The rod-like section 24 has a rotationally symmetrical cross-section. The longitudinal axis of the rod-like section 24 also corresponds to the second impact direction B2. The cross member 26 is formed on the proximal end of the rod-like section 24. The forces transmitted by the impact force deflection element 30 act on the cross member 26 or on the distal end face of the piston section 27.

[0058] The tool 20 is in the impact direction B2 or the second impact direction B2, which is in Fig. 1 is shown with an arrow, can be loaded against the action of an elastic element, namely a spring 40. The spring 40 is designed as a compression spring. The spring 40 is formed around the rod-like section 24 and is located between the cross member 26 and a collar 14 of the device housing 11. In other words, the spring 40 is clamped between the cross member 26 and the collar 14. The opening formed by the collar 14 has an inner diameter that is larger than the outer diameter of the rod-like section 24, so that the tool 20 or the tool ram 21 is slidably mounted in the collar 14.

[0059] If a force acts on the cross member 26 of the tool ram 21, this force is transferred to the spring 40, so that the compression spring 40 is compressed. The compression of the spring 40 occurs in the direction of the collar 14. As soon as no more force is exerted or acts on the cross member 26 of the tool ram 21 or on the distal end face of the piston section 27, the compression spring 40 is relieved, so that the spring 40 transfers the spring force to the cross member 26 and the tool 20 or the tool ram 21 is moved back to its original position.

[0060] The hard metal surface treatment means 23 can be formed with a flattened portion 37 facing the collar 14. The surface treatment means 23 is connected to the tool ram 21, in particular to the rod-like section 24 of the tool ram 21, by means of a positive and / or material fit. The surface treatment means 23 is connected to the rod-like section 24 after assembly or after the tool ram 21 has been inserted into the hollow cylindrical recess 25.

[0061] The piston section 27 has a lateral recess 29, in particular in the form of a longitudinal slot, into which the impact force deflecting element 30 is inserted in such a way that the stop surface 32 of the impact force deflecting element 30 assigned to the tool 20 or the tool plunger 21 interacts with the boundary surface 38 of the lateral recess 29 or the longitudinal slot facing the tool plunger.

[0062] The cross member 26 has a bevel 28. This bevel or slope allows the impact force deflection element 30 to be inserted into the lateral recess 29 of the piston section 27 and positioned there.

[0063] The connecting section 12 has a thread 15 complementary to a thread of the impact tool 50 and a locking section 16 complementary to a locking section of the impact tool 50. The device 10 according to the invention is accordingly screwed and locked to the impact tool 50. The device housing 11 has a maintenance and / or assembly opening 17 at the proximal end of the hollow cylindrical section 25. Through this opening 17, for example, the tool plunger 21 (without surface treatment means 23) with the piston section 27 can be inserted into the device housing 11. To prevent contamination of the device 10 according to the invention, in particular of the hollow cylindrical section 25, the opening 17 is provided with a screwed-in closure 18.

[0064] Fig. Figure 2 shows the device 10 according to the invention mounted on a striking tool 50. The striking tool 50 comprises a striking element 60, which is mounted in the recess 13 of the connecting section 12 so as to be longitudinally movable. The longitudinal axis l of the recess 13 and the longitudinal axis L of the hollow cylindrical section 25 form an angle whose value corresponds to the difference between 180° and the number of degrees of the deflection angle α. In the embodiment according to Fig. 2 this angle is 120°.

[0065] In Fig. 3 shows a second embodiment of a device 10' according to the invention. Accordingly, the device 10' comprises two impact force deflection elements, namely the impact force deflection element 30 and the further impact force deflection element 30'. One of the impact force deflection elements 30 is assigned to a first tool 20 acting in a first predetermined direction R1, whereas the second impact force deflection element 30' is assigned to a second tool 20' acting in a second predetermined direction R2. The two tools 20 and 20' shown are arranged and act symmetrically to the first impact direction B1 of the impact tool 60. The tools 20 and 20' are essentially like the tool according to the embodiment of the Fig. 1, ie the tools include both tool rams 21 and 21' as well as surface processing means 23 and 23'.

[0066] Furthermore, the tool plungers 21 and 21' are movable in the predetermined directions R1 and R2, respectively, against the effects of elastic elements, in particular springs 40 and 40'. The tool plungers 21 and 21' according to the second embodiment in Fig. 3, but do not include axially displaceable piston sections.

[0067] The impact force deflection elements 30 and 30' each have two stop surfaces, namely 31 and 32 and 31' and 32', respectively, wherein one stop surface 31 and 31' is assigned to the impact element 60 and the other two stop surfaces 32 and 32' are assigned to the tools 20 and 20'.

[0068] The stop surfaces 31 and 32, or 31' and 32', of the impact force deflecting elements 30 and 30' are arranged at an angle to one another. The stop surfaces 31 and 31', which are assigned to the impact element 60', have curved surface sections 31a and 31a'. In particular, these curved surface sections are concave. If the two impact force deflecting elements 30 and 30' touch, the curved surface sections 31a and 31' form a recess 45 that approximately corresponds to the shape of the tip 61 of the impact element, so that the impact movement of the impact element 60 can be transmitted evenly in a first impact direction B1 to both the first impact force deflecting element 30 and the second impact force deflecting element 30'.

[0069] The embodiment of a device 10' according to the invention according to Fig. 3, is primarily used for the simultaneous processing of several inclined surfaces.
