Description

Technical Field

[0001] This invention belongs to the field of servo motor housing welding technology, and particularly relates to a servo motor housing welding device. Background Technology

[0002] Laser welding, as a highly efficient and precise modern welding technology, plays a crucial role in the manufacturing of servo motor housings. Its high energy density, non-contact nature, and precise controllability perfectly meet the stringent requirements of housing manufacturing.

[0003] Existing technologies disclose several invention patents in the field of servo motor housing welding processing. Among them, patent publication number CN221658251U discloses a laser welding device for cast aluminum motor housings, including a welding machine base, a gantry-type precision motion module, and a laser welding head. The welding machine base is horizontally positioned, the gantry-type precision motion module is mounted on the welding machine base, and the laser welding head is vertically positioned on the moving end of the gantry-type precision motion module. A product precision positioning processing area is located at the center of the welding machine base, and this area is also equipped with a nitrogen protection device. A protective cabinet is mounted on the welding machine base. Based on welding requirements and graphics, the system can edit and accommodate different shapes. Laser welding can weld materials of different thicknesses by adjusting laser welding parameters, thereby improving work efficiency. However, this technology still has some shortcomings in its application. During laser welding, the exhaust system needs to achieve a fine balance between effectively collecting fumes and maintaining a stable shielding gas. Traditional methods usually involve installing a fixed exhaust hood on one side of the welding head, but this method has obvious limitations. If the suction is too strong, it will interfere with the normal flow of the shielding gas, affecting the gas protection effect and causing weld oxidation or defects. If the suction is insufficient, it will not be able to fully capture welding fumes, causing harmful fumes to spread. Long-term exposure to such untreated metal fumes may pose potential risks to the respiratory system and health of operators.

[0004] Based on this, the present invention designs a servo motor housing welding device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the issue that during laser welding, the exhaust system needs to achieve a fine balance between effectively collecting fumes and maintaining a stable shielding gas. Traditional methods typically involve installing a fixed exhaust hood on one side of the welding head, but this method has significant limitations. If the suction is too strong, it will interfere with the normal flow of the shielding gas, affecting the gas protection effect and leading to weld oxidation or defects. If the suction is insufficient, it will not be able to fully capture welding fumes, causing harmful fumes to spread. Long-term exposure to such untreated metal fumes may pose a potential risk to the respiratory system and health of operators. Therefore, this invention proposes a servo motor housing welding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A servo motor housing welding device includes a cabinet, a laser welding machine installed at the bottom of the cabinet, and a rotary table located below the laser welding machine for fixing and rotating the servo motor housing.

[0007] As a further description of the above technical solution: The inner wall of the first air intake is provided with a first lifting groove, and a first lifting plate is slidably connected in the first lifting groove. Multiple first springs are connected to the bottom of the first lifting plate. The first lifting plate is elastically supported and connected to the inner bottom of the first lifting groove through multiple first springs, and is supported by the first springs.

[0008] As a further description of the above technical solution: The inner sidewall of the outer frame is provided with a bridge interface corresponding to the first air intake. The inner wall of the bridge interface is provided with a second lifting groove. A second lifting plate is slidably connected in the second lifting groove. The first lifting plate and the second lifting plate are connected by a bridging rod.

[0009] As a further description of the above technical solution: The first lifting plate has a second air intake on its side end face. A suction bucket is provided inside the second air intake. Rubber pads are provided between the top and bottom of the suction bucket and the inner wall of the second air intake. A support frame is snapped into the side port of the suction bucket away from the center of the inner frame. A telescopic cylinder is connected to the support frame. A telescopic rod is sleeved inside the telescopic cylinder. A second spring is connected to the end of the telescopic rod. The telescopic rod is elastically connected to the inner end face of the telescopic cylinder through the second spring. A right-angle frame is rotatably connected to the end of the telescopic rod away from the telescopic cylinder. The other end of the right-angle frame is connected to the outer wall of the inner frame.

[0010] As a further description of the above technical solution: A lifting sleeve is fitted onto the outer side wall of the outer frame, and a second bridging rod connects the lifting sleeve to the second lifting plate.

[0011] As a further description of the above technical solution: An impeller is rotatably connected to the outer wall of the lifting sleeve, and an air inlet pipe is connected to the outer wall of the cover along the tangential direction corresponding to the impeller. An exhaust pipe is connected to the outer wall of the cover away from the air inlet pipe.

[0012] As a further description of the above technical solution: A filter and a vacuum cleaner are installed at the bottom inside the cabinet. The other end of the first suction tube is connected to a second suction tube, the other end of the second suction tube is connected to one end of the filter, the other end of the filter is connected to a third suction tube, the other end of the third suction tube is connected to the input end of the vacuum cleaner, the output end of the vacuum cleaner is connected to a return pipe, and the other end of the return pipe is connected to the end of the air inlet pipe.

[0013] As a further description of the above technical solution: The top of the cover has a lifting hole, and a lifting shaft is sleeved in the lifting hole. The bottom end of the lifting shaft is connected to the top of the lifting sleeve, and the other end of the lifting shaft is rotatably connected to a push-pull shaft. An electric push rod is installed on the top of the cover, and the telescopic end of the electric push rod is rotatably connected to the other end of the push-pull shaft.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This invention improves the efficiency of waste gas capture and waste treatment, completing capture before the waste gas diffuses, thus significantly increasing capture efficiency. It also allows for simultaneous waste treatment, reducing the impact of waste accumulation on the welding environment.

[0015] 2. In this invention, to ensure the operational stability and welding quality of the laser welding machine, the waste gas and waste material capture position is close to the welding surface, which does not interfere with the flow of protective gas, ensuring the stability of the internal gas environment of the laser welding machine, improving operational stability, and enhancing welding quality.

[0016] 3. In this invention, the cooling of the weld and the preheating treatment of the welding surface are optimized. The hot airflow continuously acts on the weld area, which effectively slows down the cooling rate of the weld, prevents hydrogen-induced cracking, preheats the area to be welded on the welding surface, removes surface impurities, increases the starting temperature, enhances the slow cooling effect, reduces residual stress and deformation, improves welding fusion, and optimizes welding process performance.

[0017] 4. In this invention, the hot airflow improves the degreasing effect on the welding surface. The reciprocating extension and retraction motion of the electric push rod flexibly changes the flow state of the hot airflow in the gap, so that the hot airflow acts more fully and evenly on the welding surface, significantly improving the degreasing effect and ensuring the cleanliness of the welding surface.

[0018] 5. In this invention, the system purification efficiency and environmental performance are improved by dynamically adjusting the height of the second air inlet to adapt to the distribution of waste gas and waste materials under different working conditions, thereby efficiently and comprehensively capturing waste gas and waste materials and improving the system purification efficiency and environmental performance.

[0019] 6. In this invention, the waste gas and waste material treatment capacity is enhanced. The tilt angle of the suction bucket changes dynamically when it is raised and lowered, expanding the range of waste gas and waste material capture. When tilted downwards, the opening direction is conducive to the intake of waste material, thereby improving the absorption efficiency. Attached Figure Description

[0025] 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.

[0026] Please see the appendix Figure 1 -Appendix Figure 13This invention provides a technical solution: a servo motor housing welding device, including a cabinet 1, a laser welding machine 2 installed at the bottom of the inner side of the cabinet 1, and a rotary table 5 set below the laser welding machine 2 for fixing and driving the servo motor housing to rotate. An inner frame 3 is provided below the welding head of the laser welding machine 2. Multiple first air intakes 4 are arranged in a circular array on the inner side wall of the inner frame 3. A cover 8 is connected to the outer side wall of the inner frame 3. An outer frame 7 is connected to the inner top of the cover 8 around the periphery of the inner frame 3. A sealing ring 6 is provided at the bottom of the outer frame 7. The sealing ring 6 is fixedly sleeved on the outer side wall of the inner frame 3. A first suction tube 10 is snapped onto the top of the cover 8. The port of the first suction tube 10 is located between the inner frame 3 and the outer frame 7. Multiple bridging frames 9 are also connected to the top of the cover 8 and are fixedly connected to the welding head through the bridging frames 9. The specific implementation method is as follows: When the laser welding machine 2 is positioned, the bottom of the inner frame 3 moves down to the welding surface of the servo motor housing to be welded. Before the laser welding machine 2 performs laser welding, the vacuum cleaner 14 is controlled to run. During operation, the vacuum cleaner 14 generates suction and applies the suction to the gap between the inner frame 3 and the outer frame 7 through the third suction pipe 13, filter 12, second suction pipe 11, and first suction pipe 10 in sequence. The suction is then distributed in multiple first suction ports 4. The waste and exhaust gas generated during the laser welding process are extracted through the multiple first suction ports 4. Compared with the traditional method of setting an exhaust hood on one side of the welding head, the waste gas can be captured before it diffuses, resulting in higher capture efficiency. At the same time, the waste can also be processed synchronously to a certain extent. Since the waste gas and waste are captured close to the welding surface, it can avoid interfering with the flow of the protective gas released by the laser welder, effectively improving the stability of the laser welding machine 2 and making the quality of laser welding higher.

[0027] Specifically, the inner wall of the first air intake 4 is provided with a first lifting groove 15, and a first lifting plate 16 is slidably connected in the first lifting groove 15. The bottom of the first lifting plate 16 is connected with a plurality of first springs 17. The first lifting plate 16 is elastically supported and connected to the inner bottom of the first lifting groove 15 through the plurality of first springs 17, and is supported by the first springs 17.

[0028] Specifically, the inner sidewall of the outer frame 7 is provided with a bridge interface 25 corresponding to the first air intake 4. The inner wall of the bridge interface 25 is provided with a second lifting groove 26. A second lifting plate 27 is slidably connected in the second lifting groove 26. The first lifting plate 16 and the second lifting plate 27 are connected by a bridging rod.

[0029] The specific implementation method is as follows: During the reciprocating lifting motion of the lifting sleeve 37 in the vertical direction, it drives the second lifting plate 27 to slide in the second lifting groove 26 through the second bridging rod 38. The second lifting plate 27 drives the first lifting plate 16 to slide synchronously in the first lifting groove 15 through the first bridging rod 28, thereby changing the height of the second air intake 18 and further expanding the capture range of exhaust gas and waste materials.

[0030] Specifically, a second air intake 18 is provided on the side end face of the first lifting plate 16. A suction bucket 20 is provided inside the second air intake 18. Rubber pads 19 are provided between the top and bottom of the suction bucket 20 and the inner wall of the second air intake 18. A support frame 21 is snapped into the side port of the suction bucket 20 away from the center of the inner frame 3. A telescopic cylinder 22 is connected to the support frame 21. A telescopic rod 23 is sleeved inside the telescopic cylinder 22. A second spring 36 is connected to the end of the telescopic rod 23. The telescopic rod 23 is elastically connected to the inner end face of the telescopic cylinder 22 through the second spring 36. A right-angle frame 24 is rotatably connected to the end of the telescopic rod 23 away from the telescopic cylinder 22. The other end of the right-angle frame 24 is connected to the outer wall of the inner frame 3.

[0031] Specifically, a lifting sleeve 37 is fitted onto the outer side wall of the outer frame 7. A second bridging rod 38 connects the lifting sleeve 37 and the second lifting plate 27. An impeller 29 is rotatably connected to the outer wall of the lifting sleeve 37. An air inlet pipe 33 is connected to the outer wall of the cover 8 along the tangential direction corresponding to the impeller 29. An exhaust pipe 34 is connected to the outer wall of the cover 8 away from the air inlet pipe 33. A filter 12 and a vacuum cleaner 14 are installed on the bottom inner side of the cabinet 1. The other end of the first suction pipe 10 is connected to a second suction pipe 11. The other end of the second suction pipe 11 is connected to one end of the filter 12. The other end of the filter 12 is connected to the first... The third suction pipe 13 has one end connected to the input end of the vacuum cleaner 14, and the output end of the vacuum cleaner 14 is connected to the return pipe 35. The other end of the return pipe 35 is connected to the end of the air inlet pipe 33. After the exhaust gas and waste are filtered by the filter 12, the blower injects hot air into the air inlet pipe 33 through the return pipe 35. Then, it flows radially along the casing 8 and directly acts on the blades of the impeller 29, driving the impeller 29 to rotate rapidly. This changes the rotation and flow of hot air in the gap between the casing 8 and the outer frame 7. On the one hand, this can have a slow cooling effect on the weld, slowing down the weld. The cooling rate helps prevent hydrogen-induced cracking to some extent. On the other hand, it preheats and degreases the area to be welded, further slowing down the cooling process, reducing residual stress and deformation, and improving weld fusion and processability. A lifting hole is provided at the top of the cover 8, and a lifting shaft 30 is sleeved inside the lifting hole. The bottom end of the lifting shaft 30 is connected to the top of the lifting sleeve 37, and the other end of the lifting shaft 30 is rotatably connected to a push-pull shaft 31. An electric push rod 32 is installed on the top of the cover 8, and the telescopic end of the electric push rod 32 is rotatably connected to the other end of the push-pull shaft 31. The electric push rod 32 performs a reciprocating telescopic motion. When the electric push rod 32 extends, its telescopic end generates a thrust on the lifting shaft 30 through the push-pull shaft 31. One end of the push-pull shaft 31 rotates around the telescopic end of the electric push rod 32, and the other end rotates around the top of the lifting shaft 30. Under the action of the thrust, the lifting shaft 30 moves downward, pushing the lifting sleeve 37 down, and the lifting sleeve 37 drives the impeller 29 to move downward. When the electric push rod 32 retracts, it drives the impeller 29 to move upward, thereby further changing the flow state of the hot air in the gap, making the degreasing effect of the hot air on the welding surface better.

[0032] The specific implementation method is as follows: When the first lifting plate 16 changes the height of the second air intake 18, it will also drive the suction bucket 20 to move synchronously. When the suction bucket 20 moves downward, the other end of the suction bucket 20 drives the telescopic rod 23 to rotate through the support frame 21 and the telescopic cylinder 22, tilting downward. The telescopic cylinder 22 extends on the surface of the telescopic rod 23 and pulls the second spring 36 to extend. Since the suction bucket 20 and the first lifting plate 16 are connected by two rubber pads 19, the tilt angle of the suction bucket 20 will continuously change during the lifting and lowering process, thereby further expanding the capture range of exhaust gas and waste. At the same time, it is more conducive to sucking up waste when the suction bucket 20 tilts downward.

[0033] Working principle and usage: First, the servo motor housing to be welded is precisely placed at the designated position on the rotary table 5 to ensure its stable installation. Then, through the control system, the laser welding machine 2 is operated to perform a precise positioning operation. The welding position information is accurately obtained using laser sensors and other equipment. Subsequently, while ensuring that the rotary table 5 rotates steadily at the preset speed, the laser welding machine 2 is started again through the control system. According to the preset welding parameters, a high-quality laser welding operation is carried out on the servo motor housing to be welded. When operating the laser welding machine 2 for precise positioning, the bottom of the inner frame 3 will descend smoothly until it precisely reaches the welding surface of the servo motor housing to be welded. Before officially starting the laser welding machine 2 for welding operations, the vacuum cleaner 14 needs to be pre-activated. After the vacuum cleaner 14 is started, its internal fan rotates at high speed, thereby generating a strong suction force. This suction force will be conducted sequentially through the third suction pipe 13, filter 12, second suction pipe 11, and first suction pipe 10 along a predetermined path, and finally act on the gap area between the inner frame 3 and the outer frame 7. Subsequently, the suction force is evenly distributed on multiple first air intakes 4. With the help of the strong adsorption capacity of these air intakes, the laser welding residue is quickly and efficiently extracted. Compared to the traditional method of capturing waste gas by setting only one exhaust hood on one side of the welding head, this solution has significant advantages over the waste gas generated during the process. Since this solution can complete the capture work before the waste gas diffuses, the waste gas capture efficiency is greatly improved. At the same time, this solution can also achieve simultaneous processing of waste to a certain extent, effectively reducing the impact of waste accumulation on the welding environment. More importantly, since the capture position of waste gas and waste is very close to the welding surface, it will not interfere with the flow of protective gas released by the laser welder, thereby ensuring the stability of the internal gas environment of the laser welding machine 2, effectively improving the operational stability of the laser welding machine 2, and ultimately enabling the laser welding quality to reach a higher level. After the exhaust gas and waste materials undergo fine filtration by filter 12, impurities and particulate matter are removed, resulting in a relatively pure airflow. Subsequently, the blower starts operating, generating strong suction and pushing force, precisely injecting the filtered hot airflow into the intake pipe 33 through the return pipe 35. After entering the intake pipe 33, the hot airflow flows smoothly along the radial direction of the casing 8 and directly impacts the blades of the impeller 29. Under the action of the hot airflow, the impeller 29 quickly begins to rotate rapidly. Its rotational motion causes the hot airflow to form a swirling flow state in the gap between the casing 8 and the outer frame 7. This hot airflow circulation method has multiple beneficial effects. On the one hand, the continuous action of the hot airflow on the weld area can... The weld seam plays a good role in slowing down the cooling rate, which can prevent hydrogen-induced cracking to a certain extent by controlling the cooling rate. This is because the slow cooling process helps hydrogen escape and reduces the accumulation of hydrogen in the weld seam, thereby reducing the risk of hydrogen-induced cracking. On the other hand, the hot gas flow also preheats the area to be welded on the welding surface during the flow process, while removing impurities such as oil on the surface. Preheating can bring the metal in the area to be welded to a suitable welding temperature, increase the welding initiation temperature, and further enhance the slow cooling effect. In addition, preheating can also reduce the residual stress and deformation generated during the welding process, improve the weld fusion, optimize the welding process performance, and thus improve the welding quality and reliability. Through precise control commands, the electric push rod 32 is driven to perform reciprocating telescopic motion. When the electric push rod 32 is in the extension phase, its telescopic end applies a thrust to the lifting shaft 30 via the push-pull shaft 31. During this process, the push-pull shaft 31 exhibits a unique motion pattern: one end rotates around the telescopic end of the electric push rod 32, while the other end rotates around the top of the lifting shaft 30, forming a lever-like transmission structure. Under the continuous action of the thrust, the lifting shaft 30 begins to move downward, thereby pushing down the lifting sleeve 37 connected to it. After being subjected to a downward force, the lifting sleeve 37 drives the impeller 2. 9. When the electric push rod 32 moves downwards in sync, the entire transmission process is reversed when the electric push rod 32 retracts. The retraction of the electric push rod 32 will drive the impeller 29 to move upwards through the linkage of the push-pull shaft 31 and the lifting shaft 30. Through this reciprocating extension and retraction motion of the electric push rod 32, the flow state of the hot air in the gap can be further flexibly changed. This dynamic flow state adjustment allows the hot air to act more fully and evenly on the welding surface, thereby significantly improving the degreasing effect of the hot air on the welding surface, ensuring that the welding surface reaches a higher cleanliness standard, and providing a good foundation for subsequent welding processes. During the reciprocating lifting motion of the lifting sleeve 37 in the vertical direction, its motion state is transmitted through a precise mechanical transmission mechanism. When the lifting sleeve 37 is lifting, it establishes a connection with the second lifting plate 27 through the second bridging rod 38, and drives the second lifting plate 27 to slide smoothly in the second lifting groove 26. The sliding of the second lifting plate 27 is not isolated, but further forms a linkage relationship with the first lifting plate 16 through the first bridging rod 28, so that the first lifting plate 16 slides synchronously in the first lifting groove 15. This multi-level linkage sliding mechanism brings significant effects. With the coordinated movement of the first lifting plate 16 and the second lifting plate 27, the height of the second air intake 18 will change accordingly. This height adjustment is not a simple position change, but aims to further expand the capture range of exhaust gas and waste. By dynamically adjusting the height of the second air intake 18, it can better adapt to the distribution of exhaust gas and waste under different working conditions, ensuring that exhaust gas and waste can be captured efficiently and comprehensively in various working scenarios, thereby improving the purification efficiency and environmental performance of the entire system. During the process of adjusting the height of the second air inlet 18 by the first lifting plate 16, the suction bucket 20 will simultaneously undergo a coordinated movement. When the first lifting plate 16 moves the second air inlet 18 to change height, the suction bucket 20 will move accordingly. During the downward movement of the suction bucket 20, its other end will apply a force to the telescopic rod 23 through the connection structure between the support frame 21 and the telescopic cylinder 22, causing the telescopic rod 23 to rotate and tilt downward. At this time, the telescopic cylinder 22 will extend on the surface of the telescopic rod 23, simultaneously pulling the connected second spring 36 to extend as well. The suction bucket 20 and the first lifting plate 16 are connected by a... Using two rubber pads 19 as a connecting medium, this design gives the suction bucket 20 a certain degree of flexibility during lifting and lowering. Due to the elasticity of the rubber pads 19, the tilt angle of the suction bucket 20 will continuously change during lifting and lowering. This dynamic change in tilt angle has significant advantages. On the one hand, it can further expand the capture range of waste gas and waste materials, enabling the suction bucket 20 to capture target substances more effectively at different heights and angles. On the other hand, when the suction bucket 20 tilts downward, its opening direction is more conducive to the intake of waste materials, thereby improving the waste material absorption efficiency and enhancing the waste gas and waste material treatment capacity of the entire system.
