Description

Technical Field

[0001] This invention relates to the field of cladding equipment technology, specifically an automatic copper alloy cladding machine. Background Technology

[0002] Overlay welding refers to the process of cladding alloy materials with certain performance characteristics onto the surface of a base material using a certain heat source, so as to give the base material special performance characteristics or restore the original shape and size of the parts. It can be used to repair the failed parts of materials due to service, and can also be used to strengthen the surface of materials or parts. Its purpose is to extend the service life of parts, save valuable materials, and reduce manufacturing costs.

[0003] Patent document CN216097169U discloses an automatic copper alloy cladding machine, including a base with symmetrically arranged grooves; first support blocks symmetrically arranged on the base; first screws arranged in pairs between the first support blocks, one end of which is connected to a first motor; a first adjusting block threadedly fitted onto the first screws, its lower end engaging with the grooves; second support blocks with guide rods between them; a second screw arranged between the second support blocks, one end of which is connected to a second motor; a second adjusting block threadedly fitted onto the second screws; a third screw fitted onto the second adjusting blocks, one end of which is connected to a third motor; a limiting block located on the upper end of the third screw, with a second guide rod between it and the third screw; a third adjusting block fitted onto the third screw and the second guide rod; a support rod connected to the third adjusting block; and a clamping cylinder located at the end of the support rod. This machine offers advantages such as precise support and control of the cladding torch movement, and stable and reliable welding.

[0004] However, the aforementioned patent uses a motor and screw to move the welding torch and welds the weld seam through two mutually perpendicular sliding welding torch paths. But, considering the aforementioned prior art and the prior art, the following problems arise: Both the prior art and the prior art use a motor to control the movement trajectory of the welding torch. Furthermore, there are various existing welding techniques, with the Z-shaped welding technique being suitable for most weld seams and alloy repairs. However, when welding larger weld seams, if the angle between the welding paths is too large, air bubbles and voids can easily form, affecting the welding effect. Also, during Z-shaped welding, it is necessary to pause slightly at both ends of the weld seam to fill the side molten pool and ensure the welding effect. However, the aforementioned devices and the prior art all control the welding torch's movement trajectory through a PLC control panel or the adjustment of the motor and other equipment. When dealing with a large number of different weld seams, adjustments must be made each time, which is very time-consuming and labor-intensive, greatly affecting welding efficiency. Summary of the Invention

[0005] The technical solution of this invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the purpose of this invention is to provide an automatic copper alloy cladding machine to solve the problem mentioned in the background art that using a PLC control panel or motor debugging to control the movement trajectory of the welding torch is time-consuming and labor-intensive when dealing with a large number of different weld seams, thus affecting work efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic copper alloy cladding machine, comprising a welding torch, an automatic adjustment track, a fixing mechanism, at least one bolt, two welding frames, an adjustment mechanism, a limiting groove, and at least one connecting shaft.

[0007] Preferably, the automatic adjustment track includes at least one outer track, at least one inner track, at least one arc-shaped connecting track, and a moving component. One end of at least one of the outer tracks is fixedly disposed on the top of one of the welding frames. At least one of the inner tracks is slidably disposed inside the corresponding outer track. At least one of the arc-shaped connecting tracks is disposed at the rotatable connection point of two adjacent inner tracks. The moving component is slidably disposed inside the inner track.

[0008] Preferably, each of the moving components includes at least one limiting slide, at least one first rack, a second gear, a dual-axis motor, a limiting disc, at least one arc-shaped rack, and at least one wedge block. At least one of the limiting slides is disposed on the corresponding outer track sidewall, at least one first rack is fixedly disposed on the corresponding inner track sidewall, the first gear is rotatably disposed on the top of the welding torch, the dual-axis motor is disposed on the top of the first gear, the limiting disc is sleeved on the upper output shaft of the dual-axis motor, the second gear is disposed at the upper output shaft end of the dual-axis motor, at least one arc-shaped rack is disposed at the connection of the two inner tracks, and at least one wedge block is disposed on the corresponding inner track sidewall.

[0009] Preferably, the fixing mechanism includes at least one fixing shaft and a fixing rod, at least one fixing shaft is inserted into the ends of the corresponding outer and inner rails, the fixing rod is disposed on the top of the fixing shaft, and at least one fixing shaft and the fixing rod are in sliding engagement.

[0010] Preferably, each of the welding frames includes at least one sliding shaft, a bottom rod, two connecting rods, a sliding groove, at least one rotating column, and a top rod. At least one rotating column is rotatably disposed at the bottom of both ends of the outer track, at least one sliding shaft is disposed at the bottom of the corresponding rotating column, the top rod is disposed at the bottom of the sliding shaft, the sliding groove is disposed at the top of the top rod, the two connecting rods are disposed at the bottom of the top rod, and the bottom rod is disposed on the bottom side wall of the connecting rod.

[0011] Preferably, the adjustment mechanism includes a threaded sleeve, a threaded rod, and a servo motor. The end of the threaded sleeve is fixedly disposed on the side wall of the bottom rod, one end of the threaded rod is threadedly connected to the inside of the threaded sleeve, and the servo motor is disposed at the other end of the threaded rod.

[0012] Preferably, each of the arc-shaped racks is a soft rack made of thermoplastic material, and the first rack is a hard rack.

[0013] Preferably, the sidewall of the wedge block is provided with an inclined surface.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) By setting up an outer track, an inner track, an arc-shaped connecting track and a moving component, the present invention allows for synchronous adaptive changes after the two welding frames calibrate the two side walls of the weld. This achieves a smaller welding trajectory angle when the weld is wider, ensuring the quality of the weld. When the weld is narrower, the welding trajectory angle is larger, preventing molten iron from overflowing from the molten pool, which would cause waste and affect the aesthetics of the weld. No manual adjustment is required. The invention can adaptively weld welds of different sizes, ensuring the quality of the weld without affecting the overall aesthetics. The operation is simple, convenient and quick.

[0016] (2) The arrangement of the first rack, the second gear, the first gear, the dual-axis motor, the limiting disc and the arc rack in this invention, due to the large density of the arc rack, in conjunction with the meshing of the second gear, ensures that the two ends of the weld seam pause for one to two seconds when performing Z-shaped surfacing welding, preventing the molten pool from not being filled and causing problems such as porosity and voids in the surfacing welding. Furthermore, the wedge block arrangement avoids the situation where the welding torch cannot turn to the next inner track when it moves along the limiting groove to the intersection of two adjacent inner tracks due to insufficient turning force.

[0017] (3) By setting a fixed shaft and a fixed rod, the present invention can be inserted after adjusting the length of the inner track and the outer track. The fourth roller can first compact the winding film wound on the winding roller to prevent slippage during welding and ensure the accuracy of welding.

[0018] (4) By setting up the first rack, the first gear, the limiting slide and the limiting disc, the present invention ensures that the limiting disc and the first gear are always in at least one meshing transmission state when the inner track is pulled out, thus avoiding the problem that the first gear cannot mesh with the first rack after the inner track is pulled out, which would prevent the welding torch from moving.

[0019] (5) In summary, this device achieves a smaller welding trajectory angle when the weld is wider, ensuring the quality of the weld. When the weld is narrower, the welding trajectory angle is larger, preventing molten iron from overflowing from the molten pool, which would cause waste and affect the aesthetics of the weld. It does not require manual adjustment and can adaptively weld welds of different sizes. At the same time, it also ensures that the weld ends pause for one to two seconds when performing Z-shaped welding, preventing the molten pool from not being filled and causing problems such as porosity and voids in the weld. Furthermore, the setting of the wedge block avoids the situation where the welding torch cannot turn to the next inner track when it moves along the limit groove to the intersection of two adjacent inner tracks due to insufficient turning force. It can also limit the inner and outer tracks to ensure the accuracy of the weld. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-6 An embodiment of the present invention provides an automatic copper alloy cladding machine, comprising a welding torch 1, an automatic adjusting track 2, a fixing mechanism 3, at least one bolt 4, two welding frames 5, an adjusting mechanism 6, a limiting groove 7, and at least one connecting shaft 8. The adjusting mechanism 6 is disposed on the right side of one of the welding frames 5, the automatic adjusting track 2 is disposed on the top of the two welding frames 5, at least one bolt 4 is threaded onto the other welding frame 5, the fixing mechanism 3 is disposed on the top of the automatic adjusting track 2, the limiting groove 7 is disposed on the bottom of the automatic adjusting track 2, the welding torch 1 is slidably disposed on the bottom of the automatic adjusting track 2 and the welding torch 1 is located within the limiting groove 7, and at least one connecting shaft 8 is rotatably disposed at the bottom rotatable connection of the automatic adjusting track 2. First, one welding frame 5 is installed above one side of the weld and then fixed with bolts 4. Next, the other welding frame 5 is moved by the adjusting mechanism 6 until it reaches the side wall of the weld. At the same time, the automatic adjusting track 2 extends and retracts adaptively according to the movement of the welding frame 5. Due to the setting of the connecting shaft 8, the corresponding automatic adjusting track 2 adjusts its angle adaptively around the connecting shaft 8. Then, the welding torch 1 moves along the pre-set automatic adjusting track 2 to deposit welds on the weld. This achieves a smaller deposit trajectory angle when the weld is wider, ensuring the quality of the deposit. When the weld is narrower, the deposit trajectory angle is larger, preventing molten iron from overflowing from the molten pool, which would be wasteful and affect the aesthetics of the deposit. No manual adjustment is required. It can adaptively deposit welds of different sizes and ensures the quality of the deposit without affecting the overall aesthetics. The operation is simple, convenient and quick.

[0029] Specifically, the automatic adjustment track 2 includes at least one outer track 201, at least one inner track 202, at least one arc-shaped connecting track 203, and a moving component. One end of at least one outer track 201 is fixedly disposed on the top of one of the welding frames 5. At least one inner track 202 is slidably disposed inside the corresponding outer track 201. At least one arc-shaped connecting track 203 of the inner track 202 is disposed at the rotatable connection point of two adjacent inner tracks 202. The moving component is slidably disposed inside the inner track 202. It is worth noting that the outer track 201, inner track 202, and arc-shaped connecting track 203 are all made of metal alloy. The welding frame 5 is moved by the adjustment mechanism 6, and the welding frame 5 drives the corresponding arc-shaped connecting track 203 to move synchronously, so that the inner track 202 extends synchronously. While the inner track 202 extends, the two adjacent inner tracks 202 rotate adaptively around the connecting shaft 8, thereby reducing the angle between the tracks. This allows for wider weld overlay operations and prevents the angle of the overlay trajectory from being too large when the weld is wide, which can lead to problems such as air bubbles and voids in the finished product. Furthermore, for narrower welds, the angle of the overlay trajectory can be adaptively increased to prevent the welding liquid in the molten pool from overflowing, which would be unsightly and wasteful.

[0030] Specifically, each of the moving components includes at least one limiting slide 21, at least one first rack 22, a second gear 23, a first gear 24, a dual-axis motor 25, a limiting disc 26, at least one arc-shaped rack 27, and at least one wedge block 28. At least one limiting slide 21 is disposed on the side wall of the corresponding outer track 201, at least one first rack 22 is fixedly disposed on the side wall of the corresponding inner track 202, the first gear 24 is rotatably disposed on the top of the welding torch 1, the dual-axis motor 25 is disposed on the top of the first gear 24, the limiting disc 26 is sleeved on the output shaft above the dual-axis motor 25, the second gear 23 is disposed at the end of the output shaft above the dual-axis motor 25, at least one arc-shaped rack 27 is disposed at the connection of the two inner tracks 202, and at least one wedge block 28 is disposed on the side wall of the corresponding inner track 202. The output shaft of the dual-axis motor 25 rotates, driving the first gear 24, the second gear 23, and the limiting disk 26 to rotate synchronously. The rotation of the second gear 23, in conjunction with the first rack 22, drives the dual-axis motor 25 to move. When it moves to the intersection of the two inner tracks 202, the second gear 23 meshes with the arc-shaped rack 27, causing the dual-axis motor 25 to drive the second gear 23 to rotate, which in turn moves through the arc-shaped rack 27. Due to the high tooth density of the arc-shaped rack 27, the moving speed of the welding torch 1 at the intersection of the two inner tracks 202 is greatly reduced. Then, after passing through the arc-shaped connecting track 203, the wedge block 28 has an inclined surface on its side wall, causing the limiting disk 26 to abut against the inclined surface, driving the dual-axis motor 25, the first gear 24, the second gear 23, and the limiting disk 26 to move. The disk 26 shifts synchronously and slides along the inclined plane. Due to inertia, the first gear 24 and the limiting disk 26 abut against the first rack 22 and the limiting slide on the other side wall of the next inner track 202. The first gear 24 meshes with the next first rack 22. Then, the output shaft of the dual-axis motor 25 rotates in the opposite direction, driving the welding torch 1 to continue moving along the limiting groove 7. This ensures that the weld ends pause for one to two seconds during Z-shaped welding, preventing the molten pool from not being filled and causing problems such as porosity and voids in the weld. Furthermore, the wedge block 28 prevents the welding torch 1 from not having enough turning force to turn into the next inner track 202 when it moves along the limiting groove 7 to the intersection of two adjacent inner tracks 202.

[0031] Specifically, the fixing mechanism 3 includes at least one fixing shaft 31 and a fixing rod 32. The fixing shaft 31 is inserted into the ends of the corresponding outer track 201 and inner track 202. The fixing rod 32 is located on top of the fixing shaft 31, and the fixing shaft 31 and fixing rod 32 are in sliding engagement. After the automatic adjusting track 2 is adjusted, the fixing rod 32 is pressed, causing the fixing shaft 31 to insert into the corresponding outer track 201 and inner track 202, thereby limiting and fixing the connection between the inner track 202 and the outer track 201, preventing slippage during welding, and ensuring the accuracy of the welding process.

[0032] Specifically, each welding frame 5 includes at least one sliding shaft 51, a bottom rod 52, two connecting rods 53, a sliding groove 54, at least one rotating column 55, and a top rod 56. At least one rotating column 55 is rotatably mounted at the bottom of both ends of the outer track 201. At least one sliding shaft 51 is mounted at the bottom of the corresponding rotating column 55. The top rod 56 is mounted at the bottom of the sliding shaft 51. The sliding groove 54 is mounted at the top of the top rod 56. The two connecting rods 53 are mounted at the bottom of the top rod 56. The bottom rod 52 is mounted on the bottom side wall of the connecting rod 53. The extension and retraction of the inner track 202 changes the angle between adjacent inner tracks 202, allowing the sliding shaft 51 to slide on the top rod 56, and adjusting the length and angle in conjunction with the inner and outer tracks 202.

[0033] Specifically, the adjustment mechanism 6 includes a threaded sleeve 61, a threaded rod 62, and a servo motor 63. The threaded sleeve 61 is fixedly mounted at one end on the side wall of the base rod 52. One end of the threaded rod 62 is threaded into the inside of the threaded sleeve 61, and the servo motor 63 is located at the other end of the threaded rod 62. The rotation of the servo motor 63 drives the threaded rod 62 to rotate, which in turn causes the threaded sleeve 61 to extend or retract.

[0034] Specifically, each of the arc-shaped racks 27 is configured as a soft rack made of thermoplastic material, while the first rack 22 is a hard rack.

[0035] Specifically, the sidewall of the wedge block 28 is provided with an inclined surface.

[0036] Working principle: First, one of the welding frames 5 is installed above one side of the weld seam and then fixed with bolts 4. The servo motor 63 rotates, driving the threaded rod 62 to rotate. The rotation of the threaded rod 62 drives the threaded sleeve 61 to extend and retract until the welding frame 5 moves to the side wall of the weld seam. At the same time, the arc-shaped connecting track 203 moves synchronously, and the inner track 202 extends and retracts adaptively according to the movement of the welding frame 5. Due to the setting of the connecting shaft 8, the corresponding outer track 201 and inner track 202 adjust their angles around the connecting shaft 8. Then, the output shaft of the dual-axis motor 25 rotates, driving the first gear 24, the second gear 23 and the limiting disk 26 to rotate synchronously. The rotation of the second gear 23, in conjunction with the first rack 22, drives the dual-axis motor 25 to move. When it moves to the intersection of the two inner tracks 202, the second gear 23 and the arc-shaped rack... The meshing of 27 causes the dual-axis motor 25 to drive the second gear 23 to rotate and move through the arc-shaped rack 27. Due to the large tooth density of the arc-shaped rack 27, the moving speed of the welding torch 1 at the junction of the two inner tracks 202 is greatly reduced. Then, after passing through the arc-shaped connecting track 203, the wedge block 28 has an inclined surface on its side wall, causing the limiting disk 26 to abut against the inclined surface, which causes the dual-axis motor 25, the first gear 24, the second gear 23 and the limiting disk 26 to shift synchronously and slide along the inclined surface. Due to inertia, the first gear 24 and the limiting disk 26 abut against the first rack 22 and the limiting slide on the other side wall of the next inner track 202. The first gear 24 meshes with the next first rack 22. Then, the output shaft of the dual-axis motor 25 rotates in the opposite direction, causing the welding torch 1 to continue to move along the limiting groove 7. The welding torch 1 performs welding on the weld seam.

[0037] Although the present invention 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 invention should be included within the protection scope of the present invention.
