[0001] The present invention relates to a work clamping system, a work carrier of the work clamping system, a machining table of the work clamping system, a machine tool, and a work machining system.

Background Art

[0002] During the machining of a work by a machine tool, a tool operated by the machine tool and the work machined thereby move relative to each other in the process of, for example, milling and / or turning operations to machine the work.

[0003] Works usually have different shapes and dimensions. Nevertheless, in order to enable standardized fixing of a wide variety of works in a machine tool in the prior art, a work carrier having a uniformly configured fixing portion and capable of fixing each of a wide variety of works to the fixing portion is usually used. The fixing operation is also referred to as "clamping the work to the work carrier" in this case.

[0004] Thus, the work carrier functions as a link for fixing the work in the machine tool for subsequent machining. The work carrier receiver for accommodating the work carrier may be, for example, rotatably drivable, whereby the angular position of the work carrier in the machine tool can be changed, or the preconditions for turning the work by continuous rotation can be prepared.

[0005] In order to increase the degree of automation of work machining, an actuator can be provided for the aforementioned work carrier, whereby, for example, the clamping state of the work on the work carrier can be defined.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The object of the present invention is to provide an improved means for securing workpieces in machine tools in fully automated production, thereby improving safety and / or the degree of automation. [Means for solving the problem]

[0007] To achieve this objective, a work clamping system according to claim 1, a work carrier according to claim 13, a machining table according to claim 15, a machine tool according to claim 17, and a work machining system according to claim 18 are provided.

[0008] Each dependent claim relates to a preferred embodiment that can be provided individually or in combination.

[0009] According to a first embodiment, a work clamping system for use in a machine tool is provided. The work clamping system comprises a machining table having a work carrier receiver, and a work carrier having a clamping device for clamping a workpiece. The work carrier receiver is preferably rotatably driven so that it can rotate continuously relative to the body of the machining table about a pivot axis passing through the center of the work carrier receiver. The work carrier is housed by the work carrier receiver, and the state in which the work carrier is housed within the work carrier receiver is the housed state, and in the housed state, the work carrier is immovably fixed to the work carrier receiver via only one fixed interface. In the housed state, the work carrier can be coupled to the work carrier receiver via at least two fluid supply interfaces, and the work carrier, in particular its clamping device, can independently receive a supply of each fluid from at least two fluid supply systems of the machining table via at least two fluid supply interfaces.

[0010] In this way, a work clamping system is realized in which the work carrier is secured by only one fixed interface and can receive at least two fluid supplies independently of each other. If necessary, for example after machining, the fixed interface can be released again, thereby separating the work carrier from the work carrier holder.

[0011] In this case, a wide variety of workpieces can be fixed to the machine tool via a workpiece carrier for subsequent machining, such as machining. Therefore, the workpiece carrier typically functions as a link between the machine tool, which usually includes a machining table, and the workpiece being machined.

[0012] Independent fluid supply is preferably understood to mean that there is no possibility of mixing the fluids of at least two fluid supply systems, at least in the work carrier and work carrier receiver.

[0013] However, the fact that they are independent fluid supplies does not mean that the fluids must be different from each other; the fluids in each fluid supply system may be the same or different.

[0014] Furthermore, the supply values ​​for each fluid supply, such as the fluid flow rate and / or supply pressure, can preferably be set independently of each other.

[0015] In this case, at least dual fluid supply allows for the independent implementation of at least two functions of the work carrier. For example, the first fluid supply system can preferably supply fluid to the clamp actuator of a clamping device to control the latter, and the second fluid supply system can, for example, supply fluid to a sensor on the work carrier to actuate the latter, which can be used, for example, to detect the clamping state or to perform control of the machine tool.

[0016] As a result, the work clamp system can be designed compactly, while additional fluid-type actuators, safety systems, or measurement systems can be mounted on the work carrier.

[0017] The fluid supply system preferably includes a transfer device capable of delivering fluid in the direction of the work carrier. In particular, the transfer device is controllable with respect to the volumetric flow rate and / or supply pressure of each fluid.

[0018] In this case, the fact that the work carrier is secured via only one fixed interface allows for a particularly compact design of the work clamp system; in short, the securing is done in only one place, rather than multiple places.

[0019] As part of an independent fluid supply, the work carrier preferably comprises two independent fluid systems, configured so that the fluids contained in each system do not mix. At least two fluid delivery interfaces are each assigned to one of the two fluid systems, so that in the containment state, at least two fluid systems can receive their respective fluids independently through their corresponding fluid delivery interfaces.

[0020] The fixed interface is preferably formed by the interaction between the fixed portion on the work carrier side and the housing portion on the work carrier receiving side.

[0021] The clamping device may be, for example, a vise or a jaw chuck, but is not limited thereto.

[0022] The fluid transfer interface is preferably formed by the interaction between the fluid transfer section of the work carrier and the fluid transfer section of a work carrier receiver that is compatible therewith, and this interaction preferably results from housing the work carrier in the work carrier receiver.

[0023] The fluid delivery part of the work carrier receiver is preferably also understood as a component of each fluid supply system, and the fluid delivery part of the work carrier is preferably also understood as a component of the fluid system of the work carrier.

[0024] The fluid delivery part of the work carrier receiver and / or the work carrier is preferably designed to automatically close and not allow each fluid to flow through when there is no interaction to form a fluid delivery interface. This can prevent, for example, uncontrolled outflow of fluid when the work carrier is removed from the work carrier receiver.

[0025] In a preferred embodiment, the central point of the fixed interface is on the axis of rotation.

[0026] Therefore, put simply, the fixed point is located on the axis of rotation so that the centrifugal force acting on the fixed interface during the rotation of the work carrier receiver is minimized, and thus the load on the fixed interface is reduced.

[0027] In a preferred embodiment, the central point of the fixed interface is on the axis of rotation.

[0028] Therefore, put simply, the fixed point is located on the axis of rotation so that the centrifugal force acting on the fixed interface during the rotation of the work carrier receiver is minimized, and thus the load on the fixed interface is reduced.

[0029] In a preferred embodiment, the receiving direction of the work carrier receiver, which is the direction in which the work carrier moves relative to the work carrier receiver to form the fixed interface, extends parallel to the axis of rotation, preferably coaxially with the axis of rotation.

[0030] As a result, the centrifugal force that can lead to loosening of the fixation does not substantially act in the receiving direction.

[0031] In a preferred embodiment, the fixed interface is designed as an HSK interface or a Capto interface. HSK is a common abbreviation for hollow shank cone.

[0032] Therefore, a standardized fixed interface can be used in the technical field, which in turn increases versatility and reduces costs.

[0033] In a preferred embodiment, the work carrier, in its accommodated state, can be coupled to a work carrier receiver via at least N additional fluid supply interfaces, and the work carrier, in particular its clamping device, can receive a supply of each fluid independently from each other via at least N additional fluid supply systems of the processing table via at least N additional fluid supply interfaces, and in addition, it can also receive a supply from at least two fluid supply systems, where,

number

[0034] Therefore, the work clamp system can be expanded by further independent fluid supply, which in particular allows for the implementation of additional functionality in the work carrier. In this case, the preferred number is N=2, so that there are a total of four fluid supply interfaces.

[0035] In a preferred embodiment, a work carrier, in particular a clamping device for a work carrier, comprises at least two fluid units, each of which is in particular a fluid-operated actuator or a fluid-operated sensor, wherein, in the housing configuration, a first fluid unit of the at least two fluid units is fluidically coupled to a first fluid supply system of at least two fluid supply systems via a first fluid delivery interface, and independently thereof, a second fluid unit of the at least two fluid units is fluidically coupled to a second fluid supply system of at least two fluid supply systems via a second fluid delivery interface.

[0036] Fluidically coupled means that a fluid can be transferred between them. The fluid unit can be designed as part of a clamping device, for example in the form of a clamp actuator, but it can also be provided separately.

[0037] Examples of actuators include clamp actuators for clamping devices that can apply clamping force to a workpiece, or coolant lubricant actuators that can supply a coolant lubricant to a workpiece for machining.

[0038] Examples of sensors include, for instance, support sensors, which preferably operate using air as the working fluid to detect proper support of a workpiece in a clamping device.

[0039] In this case, the fluid unit can be understood as part of the respective fluid system of the work carrier.

[0040] In a preferred embodiment, the first fluid supply system is configured to control the fluid supply in the first fluid unit in the containment state, and the second fluid supply system is configured to control the fluid supply in the second fluid unit independently of the fluid supply in the first fluid unit in the containment state.

[0041] In a preferred embodiment, one or more fluid supply systems are configured, in the containment state, to supply fluid from a fluid group to the work carrier, the fluid group including oil, particularly hydraulic oil, coolants and coolant lubricants, and air.

[0042] Therefore, depending on the function to be implemented, the most suitable medium for that function can be selected; for example, hydraulic fluid for clamp actuators and air for support control sensors.

[0043] In a preferred embodiment, two or more fluid delivery interfaces are arranged symmetrically with respect to a fixed interface, and / or two or more fluid delivery interfaces are equidistant from the axis of rotation.

[0044] This creates a symmetrical structure, which can reduce the effects of imbalances, particularly regarding the continuous rotation of the work carrier support.

[0045] A symmetrical arrangement may be configured such that the associated fluid delivery interface is rotationally symmetric with respect to an axis of rotation passing through the center point of the fixed interface along the accommodation direction. Furthermore, a symmetrical arrangement may be configured such that the associated fluid delivery interface is mirror-symmetric with respect to a mirror plane passing through the center point of the fixed interface, with one of the two clamp vectors of the mirror plane extending along the accommodation direction.

[0046] However, the arrangement of the fluid delivery interface should not be understood as being limited to a symmetrical arrangement. Therefore, an asymmetrical arrangement can also be chosen relative to a fixed interface.

[0047] In a preferred embodiment, each of two or more fluid supply systems may include a base body and a rotary feedthrough that delivers each fluid between a work carrier receiver rotatable relative to the base body, and these are preferably configured as a common rotary feedthrough assembly.

[0048] This provides a simple means for supplying each fluid on a rotatable work carrier, and in particular, makes it possible to place each transfer device of each fluid supply system outside the work carrier.

[0049] In a preferred embodiment, the fixed interface is located in the rear half of the work carrier support, particularly in the longitudinal direction of the work carrier support extending parallel to the axis of rotation, and the rotational feedthrough is formed in the front half of the work carrier support.

[0050] In a preferred embodiment, two or more of the fluid supply systems each include a fluid passage extending through a work carrier support and fluidically connecting each rotating feedthrough to each corresponding fluid supply interface, each fluid passage having a fluid passage portion extending parallel to the axis of rotation.

[0051] As a result of this arrangement, each fluid can be guided uniformly through the workpiece carrier support with minimal influence from the centrifugal force acting during rotation.

[0052] According to a second aspect, a work carrier is provided for use in a work clamping system according to the first aspect or one of its preferred embodiments. The work carrier comprises a clamping device for clamping a workpiece, a fixed part adapted to a housing of a work carrier receiver, and at least two fluid systems independent of each other. The work carrier is configured to be immovably fixed to the work carrier receiver only through a fixed interface formed between the fixed part and the housing. The at least two fluid systems each comprise a fluid delivery section adapted to each fluid delivery section of the work carrier receiver to form their respective fluid delivery interfaces, and the at least two fluid systems can independently receive a supply of each fluid through their respective fluid delivery sections.

[0053] Therefore, a work carrier suitable for use in a work clamp system according to a first aspect of the present invention is provided.

[0054] To immobilize the work carrier, the work carrier and the work carrier holder can be housed within the fixed interface by geometric engagement and / or mechanical engagement, so that no relative movement occurs between them.

[0055] Having only one fixed part, the work carrier features a particularly compact design. In this case, independent dual fluid supply is possible, allowing for the independent implementation of at least two functions of the work carrier, such as fluid-based clamping of a clamping device or fluid-based detection of the clamping state of a clamping device.

[0056] To release this fixation, a release mechanism of the fixation interface is preferably used, which releases the connection by shape engagement and / or mechanical engagement again, and is preferably operated by a release unit.

[0057] The work carrier can be designed according to each of the preferred embodiments of the work carrier already described in relation to the work clamping system. Repeats of these embodiments are largely omitted at this point.

[0058] In a preferred embodiment, the work carrier, in particular its clamping device, comprises at least two fluid units, each of which is a fluid-operated actuator or a fluid-operated sensor, and each can be supplied with a fluid independently of the others by at least one of two fluid systems.

[0059] According to a third aspect, a machining table is provided for use in a work clamp system according to the first aspect or one of its preferred embodiments. The machining table includes a body, a work carrier holder, and at least two fluid supply systems. The work carrier holder is preferably rotatably driven so as to be able to rotate continuously relative to the body about a pivot axis passing through the center of the work carrier holder. The work carrier holder includes a housing adapted to a fixed portion of a work carrier, and the work carrier holder is configured to immovably secure the work carrier to the work carrier holder only via a fixed interface formed between the fixed portion and the housing. Each of the at least two fluid supply systems includes a fluid delivery portion of the work carrier holder adapted to each fluid delivery portion of the work carrier to form its respective fluid delivery interface, and the at least two fluid supply systems are able to deliver their respective fluids to their respective fluid delivery portions independently of each other.

[0060] Therefore, a machining table suitable for use in the work clamping system according to the first aspect of the present invention is provided.

[0061] In a preferred embodiment, the processing table includes one or more additional work carrier supports associated with at least two corresponding fluid supply systems, each of which is rotationally driveable so as to be able to rotate continuously relative to the body around a pivot axis passing through the center of the work carrier support, each of which includes a housing adapted to a fixed portion of a work carrier, and each of the additional work carrier supports is configured to immovably secure the work carrier to each of the additional work carrier supports only through a fixed interface formed between the fixed portion and the housing, and each of the at least two associated fluid supply systems includes a fluid delivery section adapted to each fluid delivery section of the work carrier in each of the additional work carrier supports, and each of the at least two corresponding fluid supply systems can independently deliver each fluid to its respective fluid delivery section.

[0062] Therefore, the machining table is supplemented by all of the additional workpiece holders that provide the advantageous function of at least two independent fluid supplies.

[0063] According to the fourth aspect, a machine tool is provided that includes a machining table according to the third aspect or a preferred embodiment thereof.

[0064] Therefore, a machine tool is provided which includes a machining table, which is the first part of the proposed tool clamping system, and this first part can be used in combination with a work carrier, which is the second part of the proposed tool clamping system.

[0065] The machine tool is preferably a numerically controlled machine tool configured in particular for machining a workpiece.

[0066] For this purpose, the machine tool preferably comprises a machining device equipped with a rotatable workpiece spindle.

[0067] The body of the machining table is preferably movable or rotatable relative to the machine bed of the machine tool via one or more linear axes and / or one or more circular axes of the machine tool.

[0068] The machining table is preferably rotatable and / or pivotable via a first circular axis, the axis of rotation extending perpendicular to the axis of rotation of the workpiece carrier support.

[0069] According to a fifth aspect, a workpiece processing system is provided, comprising a machine tool according to a fourth aspect or one of its preferred embodiments, and one or more work carriers according to a second aspect or one of its preferred embodiments, wherein the fixing portion of one or more work carriers is adapted to one or more housing portions of a processing table such that one or more work carriers can be accommodated by one or more work carrier holders of the processing table, and each of the fluid supply portions of one or more work carriers is adapted to the fluid supply interface of the work carrier holder of the processing table to form at least two fluid supply interfaces when each of the one or more work carriers is housed in a work carrier holder.

[0070] Therefore, a workpiece machining system equipped with the proposed workpiece clamping system is provided, thereby offering all advantages, particularly in relation to machining workpieces clamped to a workpiece carrier housed in a workpiece carrier receiver on a machining table.

[0071] Further embodiments and their advantages, as well as more specific exemplary embodiments of the above-described embodiments and embodiments, will be explained below with reference to the drawings shown in the attached drawings. [Brief explanation of the drawing]

[0072] [Figure 1] A side cross-sectional view of an exemplary embodiment of the work clamp system according to the present invention is shown. [Figure 2] A perspective view of an embodiment of the work carrier according to the present invention is shown. [Modes for carrying out the invention]

[0073] It is emphasized that the present invention is by no means limited to the exemplary embodiments and their exemplary features described below. The present invention further includes modifications of the exemplary embodiments mentioned, in particular those arising from modifications and / or combinations of individual or multiple features of the exemplary embodiments described within the scope of protection of the independent claims.

[0074] Figure 1 shows a lateral cross-sectional view of an exemplary embodiment of the work clamp system 1000 according to the present invention.

[0075] The work clamping system 1000 is configured for use in a machine tool and includes a machining table 100 having a main body 101 and a work carrier receiver 102, and a work carrier 200 having a clamping device (not shown, see Figure 2) for clamping a workpiece.

[0076] The workpiece carrier holder 102 is preferably rotatably driven so that it can rotate continuously relative to the body 101 of the machining table 100 around a rotation axis R passing through the center of the workpiece carrier holder 102.

[0077] In this case, the work carrier holder 102 is preferably rotatably mounted to the main body 101 via a plain bearing.

[0078] The work carrier 200 can be accommodated by the work carrier receiver 102, and the state in which the work carrier 200 is accommodated in the work carrier receiver 102 is the accommodated state (Figure 1 shows such an accommodated state).

[0079] In its accommodated state, the work carrier 200 is immovably fixed to the work carrier receiver 102 via a single fixed interface 300.

[0080] In this case, the fixed interface 300 is preferably formed such that its center point lies on the rotation axis R. Being located on the rotation axis R means that the distance of the center point from the rotation axis can be in the range of 0% to 5% of the average diameter of the work carrier holder 102, and the diameter of the work carrier holder 102 is defined in a plane perpendicular to the rotation axis R.

[0081] More preferably, the orientation of the work carrier holder 102, which is the direction in which the work carrier 200 moves relative to the work carrier holder 102 to form a fixed interface 300, preferably extends parallel to the rotation axis R and coaxially with the rotation axis, as in Figure 1.

[0082] The fixed interface 300 is preferably formed by the interaction between the fixed portion 203 of the work carrier 200 and the corresponding housing portion 103 of the work carrier receiver 102.

[0083] In this case, the fixed interface 300 is preferably designed as an HSK interface or a CAPTO interface.

[0084] The processing table 100 preferably has a release mechanism 105 that operates the housing 103 in order to remove the fixed interface 300.

[0085] To activate the release mechanism 105, the machining table 100 preferably includes a release unit 106 for activating the release mechanism 105 on the side of the work carrier holder 102 opposite to the side having the housing portion 103, and the release mechanism 105 preferably extends along the rotation axis R so as to penetrate the work carrier holder 102.

[0086] The release mechanism 105 preferably rotates together with the work carrier support 102, but the release unit 106 does not rotate together.

[0087] In the housing configuration, the work carrier 200 may be connected to the work carrier receiver 102 via at least two fluid supply interfaces 400-1 and 400-2, and the work carrier 200, in particular its clamping device, can receive the supply of each fluid independently from each other via at least two fluid supply systems (not shown) of the machining table 100 via at least two fluid supply interfaces 400-1 and 400-2.

[0088] The fluid transfer interfaces 400-1 and 400-2 are preferably formed by the interaction of the fluid transfer sections 204-1 and 204-2 of the work carrier 200 and the fluid transfer sections 104-1 and 104-2 of the work carrier receiver 102 that are compatible therewith.

[0089] In this embodiment, two fluid supply interfaces 400-1 and 400-2 are shown, through which the work carrier 200 can receive the supply of each fluid independently of each other. Further fluid supply interfaces can be provided, but they are hidden and not shown in the diagram.

[0090] The fluid transfer interfaces 400-1 and 400-2 are preferably arranged symmetrically with respect to the fixed interface 300.

[0091] The fluid transfer interfaces 400-1 and 400-2 are preferably equidistant from the rotation axis R. Equidistant means that the distances differ from each other by less than 5%.

[0092] To deliver each fluid to two fluid delivery interfaces 400-1 and 400-2, each fluid delivery system comprises a base body 101 and a work carrier receiver 102 rotatable relative to it, each comprising a rotary feedthrough 141-1, 141-2, 141-3, and 141-4 that delivers the respective fluid, which are preferably embodied as a common rotary feedthrough assembly, as shown in Figure 1.

[0093] In the embodiment shown in Figure 1, a total of four rotary feedthroughs 141-1, 141-2, 141-3, and 141-4 are provided.

[0094] In particular, with respect to the longitudinal direction L of the work carrier holder 102 which extends parallel to the rotation axis R, the fixed interface 300 is located in the further (upper) half of the work carrier holder 102, and the rotational feedthrough is formed in the first (lower) half of the work carrier holder 102.

[0095] Each fluid supply system preferably includes a fluid passage that extends through the work carrier receiver 102 and fluidically connects each rotational feedthrough 141-1, 141-2, 141-3, 141-4 to each fluid supply interface 400-1, 400-2, and each fluid passage preferably has fluid passage sections 142-1, 142-2 that extend parallel to the rotation axis.

[0096] The length of the fluid passages 142-1 and 142-2 is preferably 50% or more of the total length of each fluid passage within the work carrier holder 102.

[0097] According to the illustrated embodiment, a work clamp system 1000 is provided in which a work carrier 200 is fixed via a single fixed interface 300 and can receive at least two types of fluids independently of each other via fluid supply interfaces 400-11 and 400-2. This allows for the advantageous realization of at least two fluid-operated functions of the work carrier 200.

[0098] Figure 2 shows a perspective view of an embodiment of the work carrier 200 according to the present invention.

[0099] The work carrier 200 is provided for use in a work clamping system (see, for example, Figure 1) and includes a clamping device 201 for clamping a work 2000, a fixing part 203 (see also Figure 1) fitted into the housing of the work carrier receiver, and at least two fluid systems independent of each other, which in this example extend through the interior of the work carrier 200 and are therefore largely invisible.

[0100] The work carrier 200 is configured to be immovably fixed to the work carrier receiver only via a fixed interface formed between the fixed part 203 and the housing part.

[0101] For this purpose, the single fixing portion 203 of the work carrier 200 is preferably located in the center of the body 202 of the work carrier 200.

[0102] Each of at least two fluid systems includes fluid delivery sections 204-1, 204-02, and 204-3, which are fitted to the fluid delivery section of the work carrier receiver, to form their respective fluid delivery interfaces, and the at least two fluid systems can independently receive the supply of each fluid through their respective fluid delivery sections 204-1, 204-02, and 204-3.

[0103] In this case, the work carrier 100 further includes four fluid systems, each having four fluid supply units 204-1, 204-2, and 204-3, one of which is obscured in the perspective view in Figure 2.

[0104] The fluid supply sections 204-1, 204-2, and 204-3 are preferably equidistant from the fixed section 203.

[0105] The illustrated work carrier 200 is advantageously capable of performing at least two fluid-based functions independently of each other, and for these functions, each fluid supply can be performed independently of each other via fluid supply units 204-1, 204-2, and 204-3 to deliver the fluid.

[0106] Although preferred embodiments of the present invention have been described in detail above with reference to the attached drawings, the present invention is not limited to these examples.

[0107] It is again emphasized that the present invention is by no means limited to the exemplary embodiments and their exemplary features described above. The present invention further includes modifications of the exemplary embodiments mentioned, in particular those arising from modifications and / or combinations of individual or multiple features of the exemplary embodiments described within the scope of protection of the independent claims.
