Description

Technical Field

[0001] The present disclosure relates to the field of machining of multiple components, and more particularly, to simultaneous machining of multiple components. Background Art

[0002] Currently, the machining solution for components (such as blades of turbines or gas turbines) is single-piece machining, that is, clamping one component each time, and it is impossible to simultaneously machine multiple components within a unit time. When there are large-batch machining orders, this machining solution results in the inability to complete the orders on time or occupying the production resources of other products, making it impossible to meet the orders of other products on time and resulting in low production efficiency.

[0003] In order to solve the problem of low efficiency in the prior art, the present application proposes improved devices, methods, and systems that can clamp multiple components at one time and simultaneously machine more than 2 components within a unit time, saving the occupation of machining device resources, and increasing the production capacity of the current machining device from single-piece production to more than 2 times the original production capacity, greatly improving the production operation efficiency. Summary of the Utility Model

[0004] In view of this, the present application proposes a device and a system for simultaneously machining multiple components, which not only save the occupation of machining device resources but also can improve the machining efficiency of the machining device within a unit time.

[0005] According to one aspect of the present application, there is provided a device for simultaneously machining multiple components. The device includes: a base having a support surface; multiple pairs of clamps arranged on the support surface of the base and configured to simultaneously clamp multiple components, wherein each pair of clamps clamps one component, and each pair of clamps includes: a first sub-clamp that clamps a first end of one component, and a second sub-clamp that clamps a second end of one component opposite to the first end, wherein the first sub-clamp and the second sub-clamp in a pair of clamps are arranged in a first side and a second side opposite to the first side of the support surface of the base in a paired manner; multiple pairs of electrodes, each pair of electrodes being respectively arranged on each pair of clamps and configured to perform electrical machining on the clamped multiple components after receiving an electric current, wherein each pair of electrodes includes: a first sub-electrode, and a second sub-electrode having a polarity opposite to that of the first sub-electrode, wherein the first sub-electrode is arranged on the first sub-clamp in a vertical direction perpendicular to the support surface, and the second sub-electrode is arranged on the second sub-clamp in the vertical direction; an electrode chuck that connects and clamps multiple pairs of electrodes and transmits an electric current to multiple pairs of electrodes.

[0006] In this way, through the collaborative arrangement of the base, multiple pairs of clamps, multiple pairs of electrodes, and an electrode chuck, the present application realizes simultaneous machining of multiple components on one device, improving the machining efficiency of the machining device.

[0007] According to an exemplary embodiment of the present application, the first sub-jig of each pair of jigs is arranged on the first side, and the second sub-jig of each pair of jigs is correspondingly arranged on the second side.

[0008] According to an exemplary embodiment of the present application, the size of the first sub-jig is larger than that of the second sub-jig.

[0009] In this way, the present application provides a specific arrangement of the jigs on the base. For example, the first sub-jig with a smaller occupied area is arranged on the first side, and the second sub-jig with a larger occupied area is arranged on the second side. Through the unified arrangement method, the maintenance convenience of the jigs is improved, the time required to adjust the positions of the jigs is reduced, and the consistency of the processed products can be further ensured, improving the product quality.

[0010] According to an exemplary embodiment of the present application, in two adjacent pairs of jigs, the two first sub-jigs are respectively arranged on opposite sides of the support surface of the base, and the two second sub-jigs are respectively correspondingly arranged on opposite sides of the support surface of the base.

[0011] In this way, the present application provides another specific arrangement of the jigs on the base. For example, the first sub-jig with a smaller occupied area and the second sub-jig with a larger occupied area are alternately arranged on the same side, making the size of the entire device smaller. In addition, this arrangement also reduces the conflicts and interferences between the jigs, meets the different processing requirements of the products, and improves the flexibility and adaptability of the production line.

[0012] According to an exemplary embodiment of the present application, in two adjacent pairs of jigs, the first pair of jigs and the second pair of jigs clamp two components in such a way that the same surfaces of the two components face the same direction, so that the same surfaces of the two components are processed simultaneously.

[0013] According to an exemplary embodiment of the present application, in two adjacent pairs of jigs, the first pair of jigs and the second pair of jigs clamp two components in such a way that the same surfaces of the two components face different directions, so that different sides of the two components are processed simultaneously.

[0014] In this way, by processing the same sides or different sides of two components simultaneously, the processes and time are reduced, and the production efficiency is improved. The present application can also flexibly adjust the jigs according to different processing requirements and workpiece characteristics to adapt to different processing scenarios.

[0015] According to an exemplary embodiment of the present application, at least one sub-electrode of multiple pairs of electrodes can be adjusted in the vertical direction by rotating the corresponding screw arranged on the electrode chuck so as to adapt to components of different sizes.

[0016] In this way, through the vertical adjustment, the electrode of the present application can be applied to workpieces of different sizes or shapes, thereby expanding the applicable range of the electrode.

[0017] According to an exemplary embodiment of the present application, the electrode chuck is a hollow square rigid body structure.

[0018] In this way, with the hollow square rigid body structure of the present application, the weight of the electrode chuck is reduced. In addition, the hollow square rigid body structure can provide a larger support area, making the electrode chuck more stable when clamping the electrode, less likely to vibrate or loosen, thereby improving the reliability of clamping.

[0019] According to an exemplary embodiment of the present application, the component is a blade of a turbine or a gas turbine, and the device simultaneously processes the sealing grooves of multiple blades through multiple pairs of electrodes.

[0020] In this way, the blade of the turbine or the gas turbine is only an example, and the workpiece to be processed in the present application is not limited to the blade of the turbine or the gas turbine.

[0021] In this way, the sealing groove is only an example of the processing feature, and the present application is not limited to the sealing groove of the blade. Those skilled in the art can process other features of the blade as needed.

[0022] According to another aspect of the present application, a system for simultaneously processing multiple components is provided. The system includes: multiple components; the aforementioned device.

[0023] In this way, the present application provides an improved system for simultaneously processing multiple components. This system not only saves the occupation of processing resources but also improves the processing efficiency per unit time.

[0041] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the embodiments of the present application. However, the present application can be implemented in many different forms and should not be construed as limited to the embodiments described herein. In the drawings, parts irrelevant to the description of the present application will be omitted for clarity. Similar reference numerals refer to similar elements throughout the description. In addition, when providing a description with reference to the accompanying drawings, although the elements are denoted by the same numerals, the reference numerals related to the elements may change, and the reference numerals are only described for convenience of description and should not be understood as limiting the concept, features, functions, or effects of the elements.

[0042] In the prior art, the processing device adopts a process scheme of single-piece single-side processing within a unit processing time. However, when the number of processing orders is large, the processing device cannot complete the processing in time, resulting in low production efficiency. In addition, when occupying the resources of other processing devices for processing, the orders of other products cannot be satisfied in time.

[0043] In view of this, the present application proposes an improved device, method and system for simultaneously processing multiple components.

[0044] Figure 1 is a schematic diagram of a system for simultaneously processing multiple components according to an embodiment of the present disclosure. As Figure 1 described, the system for simultaneously processing multiple components includes a device for simultaneously processing multiple components and multiple components 3 to be processed. The component 3 can be a blade of a gas turbine or a turbine, and the blade can have a specific curved shape to adapt to fluid flow and force conditions. The curved blade can improve the force-bearing performance of the blade and reduce the vibration of the blade, thereby improving the efficiency and reliability of the machine. However, the components of the present disclosure can also be components used in other machines and may not have a curved shape, and the present disclosure is not limited thereto.

[0045] The device for simultaneously processing multiple components includes a base 1 located at the bottom, multiple pairs of clamps arranged on the support surface of the base and configured to simultaneously clamp multiple components 3, wherein each pair of clamps clamps one component, and each pair of clamps includes: a first sub-clamp 21 that clamps the first end of one component, and a second sub-clamp 22 that clamps the second end of one component opposite to the first end, wherein the first sub-clamp and the second sub-clamp in a pair of clamps are arranged in pairs on the first side 11 of the support surface of the base and the second side 12 opposite to the first side; multiple pairs of electrodes arranged on the multiple pairs of clamps and configured to process the clamped multiple components after receiving an electric current, wherein each pair of electrodes includes: a first sub-electrode 41, and a second sub-electrode 42 with a polarity opposite to that of the first sub-electrode, wherein the first sub-electrode is arranged on the first sub-clamp in the vertical direction perpendicular to the support surface, and the second sub-electrode is arranged on the second sub-clamp in the vertical direction; an electrode chuck 5 configured to clamp the multiple pairs of electrodes and transfer an electric current to the multiple pairs of electrodes.

[0046] In the present application, multiple pairs include 2 pairs, 3 pairs... N pairs.

[0047] The processing performed by the device for simultaneously processing multiple components on the components includes electro-machining. Electro-machining is a new process that uses electrical energy and heat energy for processing, also known as electrical discharge machining; the difference between electrical discharge machining and general cutting machining is that during electrical discharge machining, the tool does not contact the workpiece to be processed, but relies on the pulsed spark discharges continuously generated between the tool and the workpiece to be processed, and uses the locally and instantaneously high temperature generated during the discharge to gradually erode the metal material.

[0048] In a device for processing multiple components simultaneously, the base 1 is one of the important components. Its main function is to support the entire device and ensure the stability and precision of the device. The base is usually made of high-strength metal materials such as cast iron or aluminum alloy to ensure it has sufficient strength and stability.

[0049] The base usually has a flat support surface and a stable support structure to ensure that the device can be stably placed on it and will not shake or move. The support surface of the base usually undergoes precision machining and grinding to ensure that its flatness and surface smoothness meet the requirements, thus ensuring the processing precision of the device.

[0050] In addition, the base usually is also equipped with adjusting bolts or nuts to adjust the levelness and balance of the device to meet the actual processing requirements. The base may also be designed with appropriate fixing holes or slots for installing and fixing other device components such as workbenches, electro-discharge machining heads, etc.

[0051] The base 1 has a first side 11 of the support surface parallel to one edge and a second side 12 opposite to the first side 11.

[0052] Multiple pairs of clamps include a first sub-clamp 21 and a second sub-clamp 22 for clamping or fixing the components to be processed. When selecting clamps, the appropriate clamp type and specifications can be determined according to the shape, size, and processing requirements of the components to be processed. The clamps can be fixed to the support surface of the base 1 by means such as bolt fixation, magnetic fixation, friction fixation, hardware fixation (such as snaps or slots), etc.

[0053] Multiple pairs of electrodes include a first sub-electrode 41 and a second sub-electrode 42. Electrodes are key components for transmitting current and generating electric sparks during the electro-machining process. Electrodes are usually made of metal materials with good electrical conductivity, and common materials include copper, aluminum, tungsten, etc. During the electro-machining process, the selection of electrodes has an important impact on the processing quality and efficiency. Appropriate electrode materials and shapes can effectively improve the processing precision and processing speed, reduce electrode wear and workpiece deformation. In addition, the surface quality of the electrodes also affects the processing effect, and the smaller the surface roughness, the better the processing effect. The first sub-electrode 41 is, for example, the negative electrode, and the second sub-electrode 42 is, for example, the positive electrode. The first sub-electrode 41 and the second sub-electrode 42 have different sizes and shapes to fit the size and shape of the component 3 to be processed.

[0054] The first sub-electrode 41 and the second sub-electrode 42 respectively have a specific interval in the vertical direction from the first sub-clamp 21 and the second sub-clamp 22 to ensure that the distance between the electrodes and the component 3 to be processed can be kept stable and precisely controlled.

[0055] Since different components have different sizes and shapes, at least one sub - electrode in multiple pairs of electrodes can be adjusted in the vertical direction by rotating the corresponding screw provided on the electrode chuck. For example, one sub - electrode in 2 pairs of electrodes is fixed, and the other three sub - electrodes can be adjusted in the vertical direction to adapt to the differences between individual parts to be processed. During this adjustment process, the fixed sub - electrode can be used as a reference, and the other three sub - electrodes are adjusted with reference to this benchmark. As another embodiment, all sub - electrodes in multiple pairs of electrodes can be adjusted in the vertical direction. As another embodiment, all sub - electrodes in multiple pairs of electrodes can not only be adjusted in the vertical direction, but also be adjusted in other directions to best fit components of different sizes.

[0056] However, in practical applications, the electrodes can also be arranged horizontally or at other specific angles, rather than being limited to the vertical arrangement.

[0057] The electrode chuck 5 is used to fix and support the components of multiple pairs of electrodes, so as to keep a certain interval between the electrodes and the part to be processed 3, so that the electro - machining process can be carried out stably. The electrode chuck usually has an adjustable clamping force and clamping position realized by screws to meet different processing requirements. By reasonably adjusting the clamping force and position of the electrode chuck 5, the efficiency and quality of electro - machining can be improved.

[0058] Figure 5 is a schematic diagram of an electrode chuck holding multiple pairs of electrodes according to an embodiment of the present disclosure. As Figure 5 shown, an electrode chuck 5 holds two pairs of electrodes simultaneously.

[0059] In addition, the contact surface between the electrode chuck 5 and multiple pairs of electrodes conducts current. The voltage of the electro - machining device usually depends on the specific equipment model and manufacturer. Generally, the voltage of the electro - machining device can be 220V, 380V or other different voltage levels.

[0060] In addition, considering the weight problem of the electrode chuck 5, in order to minimize the load on the spindle carrying the electrode chuck 5, the electrode chuck 5 of this application adopts a hollow square rigid body structure to achieve the effect of structural lightweight.

[0061] In this application, when the electrode chuck 5 obtains power from an external power source and transmits the power to multiple pairs of electrodes, multiple pairs of electrodes respectively process the sealing grooves of multiple parts 3. For example, the sealing groove is an important feature of a blade, used to install and fix a sealing strip or gasket to ensure sealing performance and effectively prevent liquid or gas leakage. However, in addition to the sealing groove, multiple pairs of electrodes can also process features such as the hole diameter and surface finish of multiple parts 3.

[0062] In the present application, multiple pairs of jigs can be arranged on the base 1 in a variety of different layouts.

[0063] Figure 2 FIG. is a schematic diagram of the arrangement of multiple pairs of jigs on the base of a device for simultaneously processing multiple components according to an embodiment of the present disclosure;

[0064] In the arrangement as shown in Figure 2 each first sub-jig 21 in each pair of jigs is arranged on the first side 11, and each second sub-jig 22 in each pair of jigs is correspondingly arranged on the second side 12. For example, the occupied area of the first sub-jig 21 is smaller than that of the second sub-jig 22. By arranging the first sub-jig 21 or the second sub-jig 22 on the same side, the maintenance convenience of the jigs is improved, the time required to adjust the jig position is reduced, and the consistency of the components to be processed (for example, blades) can be further ensured.

[0065] Figure 3 FIG. is a schematic diagram of another arrangement of multiple pairs of jigs on the base of a device for simultaneously processing multiple components according to an embodiment of the present disclosure;

[0066] In the arrangement as shown in Figure 3 in adjacent pairs of jigs, two first sub-jigs are respectively arranged on opposite sides of the supporting surface of the base, and two second sub-jigs are respectively correspondingly arranged on opposite sides of the supporting surface of the base.

[0067] For example, the occupied area of the first sub-jig 21 is smaller than that of the second sub-jig 22. By alternately arranging the first sub-jig 21 with a smaller occupied area and the second sub-jig 22 with a larger occupied area on the same side, the size of the entire device is reduced. In addition, this arrangement also reduces the conflicts and interferences between the jigs.

[0068] For example, in the arrangement shown in Figure 2 the occupied area of the base is 6600000 mm × 5200000 mm. In the arrangement shown in Figure 3 the occupied area of the base is 5860000 mm × 5200000 mm. In contrast, Figure 3 in the alternately arranged manner shown in, the size of the entire device is smaller.

[0069] [[ID=३३]] Figure 4 FIG. is a top view of multiple pairs of jigs clamping multiple pairs of components according to an embodiment of the present disclosure;

[0070] On the basis of further optimizing the arrangement shown in Figure 3 the interval between the multiple pairs of jigs shown in Figure 4 is further reduced, and the size of the entire device is also further reduced.

[0071] In addition, as Figure 4 shown, each pair of jigs clamps one component 3 respectively. Among adjacent pairs of jigs, the first sub-jig and the second sub-jig in the first pair of jigs clamp two components in such a way that the same surfaces of the two components face the same direction, so that the same surfaces of the two components are machined simultaneously; or, among adjacent pairs of jigs, the first sub-jig and the second sub-jig in the first pair of jigs clamp two components in such a way that the same surfaces of the two components face different directions, so that different sides of the two components are machined simultaneously.

[0072] As Figure 2 and Figure 3 shown, the first pair of jigs on the left and the second pair of jigs on the right contact different surfaces of the component 3 to be machined.

[0073] In this application, when the first pair of jigs on the left and the second pair of jigs on the right contact different surfaces of the component 3 to be machined, when the component 3 to be machined is a blade with a curved shape, the first pair of jigs clamps the first blade with the concave surface facing up, and the second pair of jigs clamps the second blade with the convex surface facing up.

[0074] When the first pair of jigs on the left and the second pair of jigs on the right contact the same surface of the component 3 to be machined, both the first blade and the second blade are clamped with the concave surface facing up, or both are clamped with the convex surface facing up.

[0075] Thus, within the unit processing time, different or the same surfaces of two blades are machined simultaneously. Compared with machining one surface of one blade within the unit time, the processing device of this application can increase the processing efficiency by 50%.

[0076] In this application, the arrangement manner of multiple pairs of jigs and the base 1 is not limited to this.

[0077] In the embodiments of this application, there is provided a technical solution in which multiple components are simultaneously clamped by multiple pairs of jigs on the base of the device, multiple pairs of electrodes machine the multiple components simultaneously, and one electrode head controls the multiple pairs of electrodes, so as to at least solve the technical problem of low processing efficiency caused by single-piece and single-side machining within the unit time in the prior art, and achieve the technical effects of not only saving the occupation of processing device resources, but also being able to improve the processing efficiency of the processing device within the unit time.

[0078] In the above embodiments of this application, the descriptions of each embodiment have their own focuses. For parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0079] In several embodiments provided by this application, it should be understood that the disclosed technical content can be implemented in other ways.

[0080] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
