Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, in particular to a laser welding device for processing stators and rotors. Background Art

[0002] During the manufacturing process of the stator and rotor, the silicon steel sheets first need to be processed and formed through a stamping process to obtain silicon steel sheet units that meet the size requirements; in order to improve the overall structural strength of the stator and rotor and ensure that they can withstand the corresponding electromagnetic and mechanical forces during the operation of the motor, the stamped silicon steel sheets need to be welded so that the multiple silicon steel sheets are firmly combined into a whole. However, in the existing technology, there are many problems with the welding process of the stator and rotor. On the one hand, before welding the stator and rotor, the parts to be welded need to be cleaned to remove dust and impurities on the surface, avoid cold welding and false welding during welding, and ensure the welding quality. At present, this cleaning process mostly relies on manual work, which increases the labor intensity of the operators and reduces production efficiency. On the other hand, a large amount of sparks and smoke will be generated during the welding process. Sparks fly everywhere and easily ignite flammable items around, posing a huge safety hazard. The smoke contains a variety of harmful components, such as metal oxides and harmful gases. If not controlled, they will spread in the working environment and be inhaled by the operators. In the long run, they will seriously endanger the health of the operators and also pollute the working environment. Summary of the Invention

The shell 12 not only plays a protective role, but also can wrap the welding machine 13 inside, which can prevent external factors from interfering with the welding process and can also block the spread of sparks and smoke generated by welding to a certain extent.

[0038] The dust cleaning assembly 2 includes a frame 21 fixedly connected to the center of the top of the workbench 11. A placement platform 22 is provided on the top of the frame 21. A vertical rod 23 is fixedly connected to the center of the bottom plate of the placement platform 22. The bottom of the vertical rod 23 is fixedly connected to a slide 24.

The inner cavity of the connecting groove 27 is slidably connected with a telescopic rod 28, the top of the telescopic rod 28 is fixedly connected to the placement table 22, the top of the surface of the sleeve 26 is fixedly connected with a cleaning brush 29, the bottom of the cleaning brush 29 is provided with a collar 30, and is rotatably connected to the sleeve 26, both sides of the collar 30 are provided with guide members 31, one side of the cleaning brush 29 is provided with a collecting member 32, the bottom of the surface of the sleeve 26 is provided with a rotating member 33, and the inner cavity of the sleeve 26 is provided with a clamping member 34; The frame 21 provides an installation foundation for components such as the placement table 22; the placement table 22 is used to carry the stator and rotor, and its bottom is connected to the slide 24 through the vertical rod 23, so that the placement table 22 can be flexibly moved under the drive of the electric slide rail 25, thereby facilitating the accurate delivery of the stator and rotor to the welding position and different process positions such as cleaning; the sleeve 26 is sleeved on the surface of the vertical rod 23, and through the cooperation of the connecting groove 27 and the telescopic rod 28, it not only ensures the connection between the sleeve 26 and the placement table 22, but also allows the sleeve 26 to rotate relative to each other within a certain range, thereby creating conditions for the subsequent rotation and cleaning of the cleaning brush 29 and the coordinated work at different positions; the cleaning brush 29 can directly contact the surface of the stator and rotor, effectively remove dust and impurities, greatly reduce the labor intensity of manual cleaning, and at the same time improve the cleaning efficiency and consistency, thereby providing a guarantee for the subsequent welding quality.

[0039] The ring 30 is rotatably connected to the sleeve 26, and the guide members 31 on both sides ensure the stability of the ring 30 and the cleaning brush 29 connected thereto during movement, thereby preventing shaking from affecting the cleaning effect; the collecting member 32 is responsible for collecting the dust cleaned by the cleaning brush 29 to prevent the dust from drifting into the working environment again, thereby maintaining the cleanliness of the working area; the rotating member 33 is used to drive the sleeve 26 to rotate, thereby driving the cleaning brush 29 to rotate, thereby improving the comprehensiveness and efficiency of cleaning; the clamping member 34 clamps and fixes the stator and rotor at the appropriate time, thereby ensuring that the stator and rotor are in a stable position during the cleaning and welding process.

When the stator and rotor reach the welding point, it can move quickly to shield the welding area, thereby preventing the sparks generated by the welding from scattering and reducing the fire hazard; the purification member 37 is arranged on one side of the top of the workbench 11, which can effectively collect and purify the smoke generated during the welding process, avoiding harmful components from spreading in the working environment, thereby protecting the health of the operator and reducing pollution to the environment.

[0042] It should be noted that the cooperation between the slide 24 and the electric slide rail 25, the welding machine 13, the limit switch 35 and the smoke purifier 37-1 are all existing technologies, which can be clearly understood by those skilled in the art and will not be elaborated here. Example 2

[0043] Reference Figures 1-15, which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0044] Specifically, the guide member 31 includes a guide rod 31-1 fixedly connected to both sides of the ring 30, the top and bottom of the guide rod 31-1 are fixedly connected to the guide wheel 31-2, the surface of the guide wheel 31-2 is slidably connected to the guide rail 31-3, and the side of the guide rail 31-3 away from the guide wheel 31-2 is fixedly connected to the inner cavity of the frame 21.

[0045] The cooperation of the guide rod 31-1, the guide wheel 31-2 and the guide rail 31-3 provides a stable guiding effect for the movement of the ring 30; at the same time, the guide wheel 31-2 slides in the guide rail 31-3, which can reduce the friction when the ring 30 moves, thereby making its movement smoother; this stable guiding structure helps to ensure the verticality and stability of the sleeve 26 during the descent or movement process, thereby ensuring that the cleaning brush 29 can accurately and stably clean the stator and rotor, thereby improving the consistency of the cleaning effect.

[0046] Specifically, the collecting member 32 includes a collecting port 32-1 connected to the inner cavity of the cleaning brush 29, a first hose 32-2 is wrapped around the surface of the sleeve 26, a retaining edge 32-5 is fixedly connected to the top of the ring 30, one end of the first hose 32-2 is connected to the inner cavity of the cleaning brush 29, the other end of the first hose 32-2 is connected to the ring 30, and one side of the ring 30 is connected to the second hose 32-3, one side of the second hose 32-3 passes through one group of guide rails 31-3, the frame 21 and the workbench 11, and cooperates with the purification member 37, the inner cavity of one group of guide rails 31-3 is provided with a clamping block 32-4, and one side of the clamping block 32-4 is fixedly connected to the guide rod 31-1 in one group of guide rails 31-3.

[0047] The collecting port 32-1 is connected to the inner cavity of the cleaning brush 29, and can timely absorb the dust cleaned by the cleaning brush 29; the first hose 32-2 and the second hose 32-3 are responsible for transporting the dust to the purification component 37 for treatment; the retaining edge 32-5 can prevent the first hose 32-2 from being scattered at will and causing entanglement; the second hose 32-3 is squeezed in the initial state by the clamping block 32-4 to achieve sealing. During the processing of the stator and rotor, the clamping block 32-4 will be separated from the second hose 32-3, unsealing it, so that it can work under the negative pressure of the smoke purifier 37-1, thereby achieving effective collection of the cleaning dust, avoiding the spread of dust in the workshop, and thus improving the working environment.

[0048] Specifically, the rotating part 33 includes a driving ring 33-1 which is sleeved on the bottom of the sleeve 26. The surface of the sleeve 26 is provided with a threaded protrusion 33-2 which cooperates with the driving ring 33-1. The bottom of the driving ring 33-1 is fixedly connected to a support rod 33-3, and the bottom of the support rod 33-3 is fixedly connected to the slide 24.

[0049] The inner cavity of the drive ring 33-1 is provided with a threaded groove for use with the threaded protrusion 33-2 on the surface of the sleeve 26. When the sleeve 26 moves up and down, the sleeve 26 rotates due to the action of the thread; and the drive ring 33-1 is connected to the slide 24 through the support rod 33-3 to ensure the stability of the drive ring 33-1.

[0050] Compared with simple linear cleaning, rotary cleaning can cover the stator and rotor surfaces more comprehensively, thereby improving cleaning efficiency and quality, thereby effectively cleaning dust at different positions on the stator and rotor surfaces.

[0051] Specifically, the clamping member 34 includes a slope plate 34-1 slidably connected to the inner cavity of the sleeve 26, the top of the slope plate 34-1 is fixedly connected to the bending plate 34-2, the top of the bending plate 34-2 passes through the sleeve 26 and is fixedly connected to the clamping block 34-3, the inner cavity of the sleeve 26 is fixedly connected to the reducing ring 34-4, the side of the bending plate 34-2 close to the vertical pole 23 is fixedly connected to the first spring 34-5, and the side of the first spring 34-5 away from the bending plate 34-2 is fixedly connected to the vertical pole 23.

[0052] The slope plate 34-1 can slide in the inner cavity of the sleeve 26. When the reducing ring 34-4 contacts the slope surface of the slope plate 34-1, it will push the slope plate 34-1 to move; causing the bending plate 34-2 and the clamping block 34-3 to move with the slope plate 34-1, thereby clamping the stator and rotor; the first spring 34-5 mainly functions to assist in resetting. When the external force disappears, it can drive the bending plate 34-2 and the clamping block 34-3 to return to their initial positions. At the same time, it can also play a certain buffering role, ensuring the stability of clamping and avoiding damage to the stator and rotor.

[0053] Specifically, a through slot 34-6 is provided on the top of the placement table 22 and cooperates with the clamping block 34-3. A pulley 34-7 is fixedly connected to the surface of the clamping block 34-3. A sliding slot 34-8 is provided in the inner cavity of the through slot 34-6 and cooperates with the pulley 34-7.

[0054] The through slot 34-6 on the top of the placement table 22 cooperates with the clamping block 34-3 to provide space for the movement of the clamping block 34-3; the pulley 34-7 slides in the slide slot 34-8, which can reduce the resistance of the clamping block 34-3 when it moves, thereby making the clamping process smoother; at the same time, this design can further ensure the stability and accuracy of the clamping block 34-3 when it moves, thereby better clamping and positioning the stator and rotor, thereby improving the reliability of welding.

[0055] Specifically, the bottom of the slope plate 34-1 is fixedly connected to the limiting block 34-9, and the top of the slide 24 is provided with a limiting groove 34-10, which cooperates with the limiting block 34-9. The side of the inner cavity of the limiting groove 34-10 away from the limiting block 34-9 is fixedly connected to the second spring 34-11, and the second spring 34-11 is fixedly connected to the surface of the limiting block 34-9.

[0056] By cooperating with the limit block 34-9 and the limit groove 34-10 on the top of the slide 24, the movement range of the slope plate 34-1 can be limited, thereby preventing it from excessive movement; and the second spring 34-11 mainly functions as an auxiliary reset. It is connected to the limit block 34-9 in the limit groove 34-10. When the external force disappears, it can drive the slope plate 34-1 back to its initial position, and also plays a buffering role; when the clamping block 34-3 clamps or releases the stator and rotor, the coordinated action of the limit block 34-9, the limit groove 34-10 and the second spring 34-11 can ensure the stability and repeatability of the clamping process, thereby improving the service life and working reliability of the equipment.

[0057] Specifically, the closing member 36 includes a first motor 36-1 fixedly connected to one side of the housing 12. The output shaft of the first motor 36-1 passes through the housing 12 and is fixedly connected to a rotating shaft 36-2. Both sides of the surface of the rotating shaft 36-2 are rotatably connected to fixed plates 36-3. A straight groove 36-4 is provided on the surface of the fixed plate 36-3, and a curved groove 36-5 is provided at the bottom of the straight groove 36-4. The fixed plate 36-3 is fixedly connected to the inner cavity of the housing 12, and the fixed plate 36-3 is away from the housing. A first movable rod 36-6 is provided on one side of the body 12 and is fixedly connected to the rotating shaft 36-2. A second movable rod 36-7 is hinged on one side of the first movable rod 36-6. A movable shaft 36-8 is hinged on one side of the second movable rod 36-7 and cooperates with the curved groove 36-5. A connecting arm 36-9 is fixedly connected to the surface of the movable shaft 36-8. The connecting arm 36-9 is slidably connected to the inner cavity of the straight groove 36-4. A closing plate 36-10 is fixedly connected to one side of the connecting arm 36-9.

[0058] After the first motor 36-1 is started, its output shaft drives the rotating shaft 36-2 to rotate, thereby driving the first movable rod 36-6 and the second movable rod 36-7 to swing accordingly; then the movable shaft 36-8 moves in the curved groove 36-5 and the straight groove 36-4, driving the connecting arm 36-9 and the closing plate 36-10 to move; when the stator and rotor reach the welding point, the closing plate 36-10 can quickly shield the welding area, thereby blocking the sparks generated by welding and preventing sparks from flying and causing fire and other safety accidents; as the first motor 36-1 runs, the closing plate 36-10 can further close the shell 12, thereby preventing smoke and dust from leaking, thereby ensuring a safe working environment.

[0059] Specifically, the purification component 37 includes a smoke purifier 37-1 arranged on one side of the workbench 11, and a negative pressure exhaust end 37-2 is provided on the top of the smoke purifier 37-1. One side of the top of the negative pressure exhaust end 37-2 is connected to a negative pressure pipe 37-3. The top of the negative pressure pipe 37-3 passes through the workbench 11 and is connected to the inner cavity of the workbench 11. The other side of the top of the negative pressure exhaust end 37-2 is connected to the second hose 32-3, and the top of the shell 12 is connected to the air inlet pipe 37-4.

[0060] The smoke purifier 37-1 of the purification component 37 is the core equipment. The negative pressure exhaust end 37-2 generates negative pressure, and collects the smoke generated by welding and the dust generated by cleaning through the negative pressure pipe 37-3 and the second hose 32-3 respectively; the air intake pipe 37-4 is used to replenish air to ensure the air circulation of the purification system; the purification component 37 can effectively remove harmful substances generated during welding and cleaning, thereby reducing the smoke concentration in the workshop, protecting the health of operators, and reducing pollution to the working environment, thereby meeting environmental protection requirements.

[0061] Working principle: First, place the stator and rotor on top of the rotating disk 22-2; then turn on the electric slide 25 and the smoke purifier 37-1. After the electric slide 25 is started, it drives the slide 24 to move. Since the bottom of the vertical rod 23 is fixedly connected to the slide 24, the placement table 22 also moves with it through the vertical rod 23; during the movement, the sleeve 26 remains connected to the placement table 22 through the connecting groove 27 and the telescopic rod 28, and does not affect the relative rotation of the sleeve 26. As the placement table 22 moves, the collar 30 drives the sleeve 26 to move downward under the guidance of the guide rod 31-1 and the guide rail 31-3; at this time, the clamping block 32-4 disengages from the second hose 32-3, and the smoke purifier 37-1 generates suction at the collecting port 32-1 through the second hose 32-3, the collar 30, and the first hose 32-2; at the same time, during the downward movement of the sleeve 26, the reducing ring 34-4 contacts the slope surface on the slope plate 34-1, pushing the slope plate 34-1 to slide, driving the bending plate 34-2 and the clamping block 34-3 to move, and compressing the first spring 34-5, and then the stator and rotor can be clamped and fixed by the clamping block 34-3. In addition, the driving ring 33-1 and the threaded protrusion 33-2 cooperate to make the sleeve 26 rotate while moving downward, driving the cleaning brush 29 to rotate and clean the dust on the surface of the stator and rotor; the cleaned dust enters the smoke purifier 37-1 through the collection port 32-1, the cleaning brush 29, the first hose 32-2, the collar 30, the second hose 32-3 and the negative pressure exhaust end 37-2 for collection and filtration; when the stator and rotor reach the welding point, the slide 24 triggers the travel switch 35, and the travel switch 35 sends a signal to start the first motor 36-1. Subsequently, the first motor 36-1 drives the rotating shaft 36-2 to rotate, causing the first movable rod 36-6 and the second movable rod 36-7 to swing, and then drives the movable shaft 36-8 to move in the curved groove 36-5, and causes the connecting arm 36-9 and the closing plate 36-10 to swing, so that the closing plate 36-10 is in a vertical state, shielding the sparks generated by welding; as the first movable rod 36-6 and the second movable rod 36-7 continue to swing, the movable shaft 36-8 enters the straight groove 36-4 from the curved groove 36-5, driving the connecting arm 36-9 and the closing plate 36-10 to move toward the shell 12, so that the closing plate 36-10 can be used to seal the shell 12 to prevent leakage of welding smoke; subsequently, the welding machine 13 starts to weld the stator and rotor, and the smoke generated by welding is collected and purified by the smoke purifier 37-1 through the negative pressure pipe 37-3.

[0062] When different parts need to be welded, the second motor 22-1 is turned on, and the second motor 22-1 drives the rotating disk 22-2 to rotate, thereby adjusting the direction of the stator and rotor to facilitate welding operations on different parts; after welding is completed, the components are reset according to the reverse process and wait for the next operation. Example 3

[0063] Reference Figure 7-Figure 9 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0064] Specifically, the top of the placement table 22 is fixedly connected to the second motor 22 - 1 , and the output shaft of the second motor 22 - 1 is fixedly connected to the rotating disk 22 - 2 .

[0065] After the second motor 22-1 on the top of the placement table 22 is started, its output shaft drives the rotating disk 22-2 to rotate; when different parts of the stator and rotor need to be welded, the orientation of the stator and rotor can be easily adjusted by rotating the rotating disk 22-2 through the second motor 22-1, thereby eliminating the need for manual adjustment of the stator and rotor position, thereby improving the convenience and efficiency of welding, and making the welding operation more flexible, thereby being able to adapt to the requirements of different welding processes for the stator and rotor position.

[0066] It should be noted that the surface of the clamping block 34 - 3 is provided with balls, and the balls on the surface of the clamping block 34 - 3 reduce the friction when the stator and rotor rotate, thereby adjusting the orientation of the stator and rotor.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
