Description

Technical Field

[0001] This utility model relates to the field of laser cladding technology, and more specifically, to an ultrasonic vibration-assisted wire feeding laser cladding device. Background Technology

[0002] Laser cladding is an advanced surface engineering and additive manufacturing technology. Its core principle is to use a high-energy laser beam as a heat source to melt the cladding material (such as metal wire) and a thin layer on the substrate surface simultaneously. This melted material then rapidly solidifies, forming a coating with excellent metallurgical bonding and superior properties (such as wear resistance, corrosion resistance, and high-temperature resistance). This technology, with its low heat input, low dilution rate, high bonding strength, and precision forming capabilities, is widely used for the repair, strengthening, and remanufacturing of critical mechanical components. Among these, wire-feed laser cladding has become an important development direction due to its high material utilization, good process stability, and environmental friendliness (compared to powder feeding). However, traditional wire-feed laser cladding processes still face challenges such as difficulty in controlling molten pool fluidity, coarse grains, and the generation of metallurgical defects such as porosity and residual stress, which restricts its further application in the manufacturing of high-end components.

[0003] To overcome the aforementioned metallurgical defects and improve the quality of the cladding layer, ultrasonic vibration-assisted technology has been introduced into the wire-feeding laser cladding process. Existing "ultrasonic vibration-assisted wire-feeding laser cladding devices" typically integrate an ultrasonic vibration generator (transducer) and an amplitude transformer into a traditional wire feeding mechanism or substrate clamp. Its working principle is to directly transmit high-frequency (typically 15-40kHz), low-amplitude mechanical vibration to the cladding wire through the wire feeding nozzle, or to the substrate through the clamp. This introduced ultrasonic energy generates cavitation, acoustic flow, and mechanical disturbance effects within the molten pool, effectively breaking up dendrites, refining the solidification structure, promoting the escape of bubbles and impurities, and improving the uniformity of elemental distribution. Therefore, this technology has been proven to significantly reduce the porosity and crack sensitivity of the cladding layer, and improve its hardness, toughness, and fatigue performance, making it an effective means of preparing high-performance cladding layers.

[0004] While ultrasonic vibration-assisted wire feeding technology has brought significant improvements in metallurgical quality, the engineering practicality of existing devices, especially in terms of accessibility in complex spaces, still has significant shortcomings. This device integrates a wire feeding mechanism, a vibration unit (transducer and amplitude transformer), and adjustment mechanisms necessary to adapt to different process parameters (such as wire feeding angle and defocusing amount). The core problem lies in the fact that the adjustment arms or connecting mechanisms used for precise adjustment of the wire feeding posture are typically rigid frames or linkages with fixed overall dimensions, lacking a compact, foldable, or significantly retractable flexible design. When the laser cladding head needs to operate deep into the workpiece's internal cavity, narrow grooves, or densely packed, confined spaces, these bulky, fixed-shape adjustment arms interfere with the surrounding structure, preventing access to the optimal processing position and severely limiting the application of this advanced technology to complex components (such as the internal cavity of aero-engine blades, the inner wall of deep holes, and densely packed tube bundles).

[0005] For example, in Chinese patent application No. 202322772512.7, entitled "An Adjustable Coaxial Wire Feeding Auxiliary Device for Laser Cladding Head," although the wire feeding angle is flexibly adjusted through a rotating sleeve and adjusting bolt, the overall adjustment mechanism consists of multiple rigid connecting rods, supports, and sleeves coaxially assembled, forming a rigid integral structure with a fixed axial length and an invariable radial profile. This design is fine for open-space operations, but when faced with scenarios requiring deep hole penetration or cladding within confined cavities, its fixed overall length and large radial dimension become insurmountable physical obstacles, preventing the advantages of ultrasonic vibration assistance from being utilized in critical narrow areas. In other words, the contradiction between the fixed volume of the adjusting arm in existing technologies and the requirements of working in narrow environments is an objective and urgent problem to be solved. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies: the adjusting arms or connecting mechanisms used for precise adjustment of wire feeding posture are typically rigid frames or linkages; when the laser cladding head needs to operate deep into the inner cavity of the workpiece, narrow grooves, or densely packed small spaces, these bulky and fixed-shape adjusting arms will interfere with the surrounding structure, making it impossible to reach the optimal processing position, which severely limits the application of this advanced technology in complex components (such as the inner cavity of aero-engine blades, the inner wall of deep holes, and the space between dense tube bundles). Therefore, an ultrasonic vibration-assisted wire feeding laser cladding device is proposed.

[0007] The specific technical solution is as follows: An ultrasonic vibration-assisted wire feeding laser cladding device includes a wire feeding mechanism mounted on a laser cladding head. The wire feeding mechanism is assembled on the laser cladding head via an adjusting arm. The adjusting arm includes an X-axis adjusting arm, a Y-axis adjusting arm, and a Z-axis adjusting arm, all of which have the same structure. The X-axis adjusting arm includes a housing, inserting tubes, and a telescopic component. The housing is unidirectionally open, and the end of the housing away from the opening is mounted on the laser cladding head. Multiple inserting tubes are provided and interlocked sequentially. The inserting tubes are movably inserted into the housing. The telescopic component is inserted and fixed inside the housing and is located at the center of the inserting tubes. When the telescopic component extends, multiple inserting tubes can be pushed out from inside the housing. When the telescopic component shortens, multiple inserting tubes can be completely stored inside the housing. Before the laser cladding head begins operation, the adjusting arm is activated. The adjusting arm moves the X-axis, Y-axis, and Z-axis adjusting arms to extend and retract, reaching the optimal processing position. When any one of the X-axis, Y-axis, or Z-axis adjusting arms extends, multiple insertion tubes can be pushed out from inside the storage shell. When the extending and retracting arms retract, multiple insertion tubes can be stored inside the storage shell. This allows the adjusting arm to adjust the volume along with the extension and retraction of the X-axis, Y-axis, and Z-axis adjusting arms, enabling it to work with the laser cladding head in some narrow processing environments, such as deep into the inner cavity of the workpiece, narrow grooves, or densely structured confined spaces.

[0008] In a further technical solution, the X-axis adjusting arm, Y-axis adjusting arm, and Z-axis adjusting arm are vertically distributed and assembled together by a mounting frame.

[0009] In a further technical solution, the telescopic component is inserted and fixed at the center of the storage shell and is distributed in a straight line along the main body of the storage shell.

[0010] A further technical solution is that the insertion tube is through-hole at both ends; an anti-detachment protrusion is provided between the multiple insertion tubes to prevent them from detaching from each other during stretching. The inner and outer surfaces of the multiple insertion tubes are both smooth to allow for smooth insertion.

[0011] A further technical solution is that the telescopic component includes an electric telescopic rod and a fixing plate. One end of the electric telescopic rod is fixed inside the storage shell and is located at the center of the insertion tube. The fixing plate is fixed at the end of the electric telescopic rod away from the storage shell, and the electric telescopic rod does not contact the insertion tube. The fixing plate is fixed at the end of the outermost one of the multiple insertion tubes.

[0012] Alternatively, the electric telescopic rod can be replaced with a hydraulic telescopic rod or a pneumatic telescopic rod.

[0013] In a further technical solution, the wire feeding mechanism includes a wire output head and an angle adjustment component. The wire output head is mounted on the angle adjustment component, and the angle adjustment component is mounted on the Z-axis adjustment arm. The angle adjustment component is used to adjust the angle at which the wire output head assists the laser cladding head in its operation.

[0014] The optimized angle adjustment component includes a clamping plate assembly and a connecting plate. The clamping plate assembly is installed at the end of the connecting plate. The clamping plate assembly includes two arc-shaped clamping plates, which are symmetrically distributed and fixed together by bolts. The two arc-shaped clamping plates are used to clamp and fix the wire outlet head.

[0015] The end of the connecting plate away from the clamping plate assembly is rotatably mounted on the positioning plate. The positioning plate is provided with a locking pin, which is used to limit the rotation of the connecting plate. After the threaded end of the locking pin is turned out, the locking pin releases the limitation of the connecting plate on the locking pin, and the threaded end can adjust the rotation angle.

[0016] Compared with existing technologies, the ultrasonic vibration-assisted wire feeding laser cladding device of this invention can achieve the following: Before the laser cladding head starts working, the adjusting arm is activated. The adjusting arm moves the X-axis adjusting arm, Y-axis adjusting arm, and Z-axis adjusting arm to extend and retract to reach the optimal processing position. When any one of the X-axis adjusting arm, Y-axis adjusting arm, or Z-axis adjusting arm extends, multiple insertion tubes can be pushed out from inside the storage shell. When the extending and retracting arm is activated, multiple insertion tubes can be stored inside the storage shell. This allows the adjusting arm to adjust the volume along with the extension and retraction of the X-axis adjusting arm, Y-axis adjusting arm, and Z-axis adjusting arm, so that it can work with the laser cladding head in some narrow processing environments, such as working deep inside the workpiece cavity, narrow groove, or densely structured confined space. Traditional single-bar telescopic booms are prone to deflection and vibration at the end due to the cantilever beam effect when extended over a long stroke, affecting processing accuracy. The multi-layered interlocking tube nesting design of this invention, when extended, has each layer of tube walls supporting each other, forming a distributed anti-bending structure similar to a "socket wrench," with overall rigidity far exceeding that of a single rod of the same outer diameter. When fully retracted, the components are integrated into a compact whole, which is equally stable. This structural rigidity, dynamically optimized according to the extension length, ensures that even in narrow spaces, when the adjusting arm needs to extend in multiple stages to reach deeper positions, the laser cladding head can still maintain extremely high positioning stability and anti-interference capability, providing a fundamental mechanical guarantee for high-quality cladding. Laser cladding sites often involve splashes, dust, and high temperatures; traditional open guide rails or lead screw adjusting arms are prone to contamination. In this invention, the main moving component of the adjusting arm is an insert tube, which is sealed and stored inside a housing during non-working periods and non-extension sections. This housing naturally forms a protective shell, effectively isolating most of the dust and metal splashes on-site, reducing contamination and wear on precision sliding surfaces, and improving the reliability and service life of the system. At the same time, the compact storage shape also facilitates centralized air cooling or sealing protection of core components, which is a crucial and unexpected maintainability advantage in confined and harsh processing environments.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the protection scope of this utility model.

[0020] One embodiment of this utility model is as follows: Figures 1-7 As shown: An ultrasonic vibration-assisted wire feeding laser cladding device includes a wire feeding mechanism mounted on a laser cladding head 100, wherein the wire feeding mechanism is mounted on the laser cladding head 100 via an adjusting arm 200; Therefore, after the wire feeding mechanism flexibly adjusts the angle via the adjusting arm 200, it follows the laser cladding head 100 to work in some narrow processing environments; As for the "laser cladding head 100" and the laser cladding technology that assists the "laser cladding head 100", they are all existing technologies. They can be purchased directly on the market and are directly applicable equipment. They can be purchased arbitrarily by those skilled in the art according to their own needs. They are not what this invention is meant to protect, and will not be described in detail here. The adjusting arm 200 includes an X-axis adjusting arm 210, a Y-axis adjusting arm 220, and a Z-axis adjusting arm 230, all of which have the same structure. The X-axis adjusting arm 210 includes a housing 2101, an insert tube 2102, and a telescopic component 2103. The housing 2101 has a one-way opening, and the end of the housing 2101 away from the opening is mounted on the laser cladding head 100. Multiple insert tubes 2102 are provided and are interwoven sequentially. The insert tubes 2102 are movably inserted into the housing 2101. The telescopic component 2103 is inserted and fixed inside the housing 2101 and is located at the center of the insert tubes 2102. When the telescopic member 2103 extends, multiple insertion tubes 2102 can be pushed out from inside the storage shell 2101; when the telescopic member 2103 shortens, multiple insertion tubes 2102 can be completely stored inside the storage shell 2101.

[0021] Therefore, the adjusting arms or connecting mechanisms used for precise adjustment of wire feeding posture are typically rigid frames or linkages. When the laser cladding head needs to operate deep into the workpiece cavity, narrow grooves, or densely packed, confined spaces, these bulky, fixed-shape adjusting arms interfere with the surrounding structure, preventing them from reaching the optimal processing position. This severely limits the application of this advanced technology in complex components (such as the inner cavity of aero-engine blades, the inner wall of deep holes, and the space between dense tube bundles). This application can achieve the following: Before the laser cladding head 100 starts working, the adjusting arm 200 is activated. The adjusting arm 200 moves the X-axis adjusting arm 210, Y-axis adjusting arm 220 and Z-axis adjusting arm 230 to extend and retract to reach the optimal processing position. When any one of the X-axis adjusting arm 210, Y-axis adjusting arm 220 and Z-axis adjusting arm 230 is activated to extend the telescopic component 2103, multiple insertion tubes 2102 can be pushed out from inside the storage shell 2101. When the telescopic component 2103 is activated to shorten, multiple insertion tubes 2102 can be stored inside the storage shell 2101. This allows the adjusting arm 200 to adjust the volume of the X-axis adjusting arm 210, Y-axis adjusting arm 220 and Z-axis adjusting arm 230 on the basis of telescopic adjustment, so that it can follow the laser cladding head 100 to work in some narrow processing environments, such as working deep into the inner cavity of the workpiece, narrow grooves or densely structured small spaces.

[0022] Another embodiment of this utility model, such as Figure 3 and Figure 4 As shown: The X-axis adjusting arm 210, Y-axis adjusting arm 220 and Z-axis adjusting arm 230 are vertically distributed and are assembled together by mounting frame 240.

[0023] like Figure 5 and Figure 6 As shown: The telescopic component 2103 is inserted and fixed at the center of the storage shell 2101 and is distributed in a straight line along the main body of the storage shell 2101.

[0024] like Figure 5 and Figure 7 As shown: the insertion tube 2102 is through at both ends; anti-detachment protrusions are provided between the multiple insertion tubes 2102 to prevent them from falling off each other during stretching. The inner and outer surfaces of the multiple insertion tubes 2102 are both smooth to allow for smooth insertion.

[0025] Another embodiment of this utility model, such as Figure 5 and Figure 8 As shown: The telescopic component 2103 includes an electric telescopic rod 2104 and a fixing plate 2105. One end of the electric telescopic rod 2104 is fixed to the inner end of the storage shell 2101 and is located at the center of the insertion tube 2102. The fixing plate 2105 is fixed to the end of the electric telescopic rod 2104 away from the storage shell 2101. The electric telescopic rod 2104 does not contact the insertion tube 2102. The fixing plate 2105 is fixed to the end of the outermost one of the multiple insertion tubes 2102.

[0026] As for the "electric telescopic pole 2104" and the power supply wiring technology of the "electric telescopic pole 2104", they are existing technologies, which can be purchased directly on the market and can be used directly; they are also equipment that can be purchased arbitrarily by those skilled in the art according to their own needs; they are not what this invention is meant to protect, and will not be described in detail here. Optimized, such as Figure 5 and Figure 8 As shown: The electric telescopic rod 2104 can be replaced by a hydraulic telescopic rod or a pneumatic telescopic rod.

[0027] The technology of hydraulic or pneumatic telescopic rods is also existing technology. They can be purchased directly on the market, assembled by purchasing parts, or learned from journals. Those skilled in the art can choose to purchase them according to their own needs. Hydraulic or pneumatic telescopic rods are not the subject of this application and will not be described in detail here.

[0028] Another embodiment of this utility model, such as Figure 2 As shown: The wire feeding mechanism includes a wire outlet 300 and an angle adjustment component 400. The wire outlet 300 is mounted on the angle adjustment component 400, and the angle adjustment component 400 is mounted on the Z-axis adjustment arm 230. The angle adjustment component 400 is used to adjust the angle at which the wire outlet 300 assists the laser cladding head 100 in its operation.

[0029] As for the "thread output head 300" and its working technology, they are existing technologies that can be purchased directly on the market and are directly applicable. They can be purchased arbitrarily by those skilled in the art according to their own needs. They are not what this invention is meant to protect, and will not be described in detail here.

[0030] In summary: Before the laser cladding head 100 performs processing operations, its integrated reconfigurable adjusting arm 200 is first activated. This adjusting arm is not a traditional fixed truss structure, but consists of three core modules arranged orthogonally in space, each with autonomous extension, retraction, and volume transformation capabilities: the X-axis adjusting arm 210, the Y-axis adjusting arm 220, and the Z-axis adjusting arm 230. Its workflow and core mechanism are as follows: Collaborative telescopic positioning: Based on the processing path planning, the control system coordinates the telescopic movements of the X-axis adjusting arm 210, Y-axis adjusting arm 220 and Z-axis adjusting arm 230, driving the laser cladding head 100 at the end and the integrated wire feeding device to move precisely in three-dimensional space to reach the preset "optimal processing position". Unique volume-following adjustment mechanism: Position adjustment and volume adjustment are completed synchronously and as a whole; taking the X-axis adjusting arm 210 as an example, its core structure consists of a fixed "storage shell 2101" and multiple nested "intercalation tubes 2102" inside. When extension is required, the telescopic component 2103 (such as an electric push rod or precision lead screw) moves, not simply pushing out a single rod, but smoothly pushing out the multiple layers of intercalation tubes 2102 step by step and coaxially from the storage shell like a telescope tube; conversely, when shortening, the telescopic component 2103 pulls back, orderly retracting all the intercalation tubes 2102 and compactly accommodating them inside the storage shell.

[0031] Operating mode adapted to confined environments: The Y-axis adjusting arm 220 and the Z-axis adjusting arm 230 operate on the same principle. Through this mechanism, the maximum physical space (volume) occupied by the entire adjusting arm 200 is minimized at any extension or retraction stroke. When the laser cladding head needs to penetrate deep into the inner cavity of the workpiece, narrow grooves, or densely structured areas, the three-axis adjusting arm can first enter in a compact "fully retracted" form, and then extend to the necessary length only in the necessary axes according to the shape of the internal space. This satisfies process accessibility while minimizing interference with surrounding narrow walls, achieving flexible operation capabilities in extremely confined spaces.

[0032] Traditional single-bar telescopic arms are prone to deflection and vibration at the end due to the cantilever beam effect when extended over a long stroke, affecting processing accuracy. The multi-layered interlocking tube nesting design of this invention, when extended, has each layer of tube walls supporting each other, forming a distributed anti-bending structure similar to a "socket wrench," with overall rigidity far exceeding that of a single bar of the same outer diameter. When fully retracted, the components are integrated into a compact whole, which is equally stable. This structural rigidity, dynamically optimized according to the extension length, ensures that even in narrow spaces, when the adjusting arm needs to extend in multiple stages to reach deeper positions, the laser cladding head 100 can still maintain extremely high positioning stability and anti-interference capability, providing a basic mechanical guarantee for high-quality cladding. The telescopic and volumetric capabilities of the X-axis adjusting arm 210, Y-axis adjusting arm 220, and Z-axis adjusting arm 230 create conditions for low-cost passive space safety detection. Since the physical envelope of the adjusting arm is precisely controllable, the control system can reversely utilize this characteristic. Before entering unknown narrow areas, the programmable control adjusting arm operates in a "minimum incremental tentative extension" mode. By monitoring the changes in current or resistance of the motors of each axis telescopic component, it is possible to indirectly sense whether there is contact or interference with the external environment. This "tactile" sensing capability based on body sensing, without the need for additional external sensors, is an unexpected and low-cost space adaptive safety function that can effectively prevent equipment from being damaged by collisions during blind operation.

[0033] Laser cladding sites often involve splashes, dust, and high temperatures; traditional open guide rails or lead screw adjusting arms are prone to contamination. In this invention, the main moving component of the adjusting arm 200 is the insertion tube 2102, which is sealed and stored inside the storage shell 2101 during non-working periods and non-extended sections. This storage shell 2101 naturally forms a protective shell, effectively isolating most of the dust and metal splashes on site, reducing contamination and wear on precision sliding surfaces, and improving the reliability and service life of the system. At the same time, the compact storage shape also facilitates centralized air cooling or sealed protection of core components, which is a crucial and unexpected maintainability advantage in confined and harsh processing environments.

[0034] Another embodiment of this utility model, such as Figure 2 As shown: The angle adjusting component 400 includes a clamping plate assembly and a connecting plate. The clamping plate assembly is installed at the end of the connecting plate. The clamping plate assembly includes two arc-shaped clamping plates, which are symmetrically distributed and fixed together by bolts. The two arc-shaped clamping plates are used to clamp and fix the wire head 300.

[0035] like Figure 2 As shown: The end of the connecting plate away from the clamping plate assembly is rotatably mounted on the positioning plate. The positioning plate is provided with a locking pin, which is used to limit the rotation of the connecting plate. After the threaded locking pin is turned out, the locking pin releases the limitation of the connecting plate on the locking pin. The threaded end 300 can adjust the rotation angle.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
