Description

Technical Field

[0001] This application relates to the field of stator welding equipment technology, specifically a stator assembly round welding equipment. Background Technology

[0002] The stator is the stationary part of an electric motor or generator. It consists of three parts: the stator core, the stator windings, and the frame. In the motor manufacturing process, stator components often require a circular welding operation during processing. This operation aims to splice and weld multiple stator components together to ultimately form a complete circular stator structure.

[0003] For example, the patent with publication number CN209811497U discloses a new type of segmented stator core assembly and welding machine, which includes a machine box, safety cover, processing table, stator tightening mechanism, stator end face shaping mechanism, stator welding mechanism, stator core, indicator lights and control panel. It can shorten production time, improve work efficiency, has a high degree of automation, and the stator core is easy to install. It can clamp and assemble multiple stator cores at the same time without loosening during the clamping and assembly process.

[0004] However, in actual application, although the stator core round welding machine of the above-mentioned patent has a fume treatment hood installed inside the safety cover, the fume treatment hood has a simple structure and limited coverage, making it difficult to form a relatively effective negative pressure adsorption area. As a result, its smoking range is narrow and its smoking efficiency is low. Consequently, the smoke and harmful gases generated during the welding process are not easily collected, which can easily cause certain harm to the health of the operators. Long-term inhalation of such harmful substances may also cause various respiratory diseases. Therefore, it is necessary to provide a stator component round welding equipment to solve the above problems. Utility Model Content

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] like Figure 1 and Figure 2As shown, this application provides a stator assembly splicing and welding equipment, including a welding box 1. The welding box 1 has an overall rectangular structure and is equipped with universal wheels with brakes (not shown in the figure) at the bottom for easy movement and fixation of the equipment. A processing table 11 is fixedly installed in the middle of the welding box 1. The surface of the processing table 11 is flat and smooth to ensure stability during stator placement and welding. An adapter frame 12 is bolted to the lower part of the processing table 11. A welder 5 is installed on the processing table 11. The welder 5 is bolted to the processing table 11 and is located on both sides of the stator. This is prior art and consists of a mounting base, slide rail, sliding seat and electric push rod, etc. It can be adjusted in position and connected to the control system to weld the stator splicing joint.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, a lifting assembly 2 is installed at the lower part of the processing table 11. The lifting assembly 2 is used to adjust the height and angle of the stator to adapt to the welding operation requirements. The lifting assembly 2 includes a mounting frame 21 that is bolted to the lower part of the processing table 11. The mounting frame 21 is a frame structure with strong load-bearing capacity. A motor module 22 is bolted to one side of the mounting frame 21. The motor module 22 is a ball screw module driven by a servo motor with high positioning accuracy. An assembly frame 23 is bolted to the motor module 22. The assembly frame 23 is lightweight and strong. The motor module 22 is existing technology and can make the assembly frame 23 rise and fall vertically. The rising and falling speed can be flexibly adjusted within a certain range according to the actual welding requirements to meet the height adjustment requirements of stators of different specifications.

[0033] A rotary motor 24 is bolted to the assembly frame 23. This rotary motor 24 is a geared motor, characterized by high output torque and stable operation after being powered on. A rotating rod 25 is coaxially mounted to the output end of the rotary motor 24 via a key connection. The key connection ensures the reliability of power transmission between the rotary motor 24 and the rotating rod 25, preventing slippage. One end of the rotating rod 25 extends to the upper part of the adapter frame 12 and the processing table 11, and a retainer 26 is bolted to it. The surface of the retainer 26 is hardened, resulting in high hardness, which can withstand the pressure of the stator body 27 and is not easily worn. The stator body 27 is placed on the retainer 26.

[0034] In actual operation, the motor module 22 receives the electrical signal sent by the control system, the servo motor starts and drives the ball screw to rotate. The two ends of the ball screw are mounted on the mounting frame 21 through bearing seats to ensure its stability during rotation. The ball screw is fitted with a matching nut seat, and the nut seat is fixedly connected to the mounting frame 23 by bolts. Since the ball screw is connected to the mounting frame 23 through the nut seat, and the two sides of the mounting frame 23 are slidably connected to the guide rails on the mounting frame 21, it can only move vertically due to the restriction of the guide rails. Therefore, the mounting frame 23 will move up and down along the guide rails to adjust the height position of the stator body 27 to make it at the optimal welding height.

[0035] When the welding angle of the stator body 27 needs to be adjusted, the rotating motor 24 is powered on and runs. After the torque is amplified by the internal reduction mechanism, the output torque drives the rotating rod 25 to rotate. The rotating rod 25 rotates smoothly under the support of the adapter frame 12, thereby driving the card holder 26 and the stator body 27 placed on the card holder 26 to rotate synchronously. Its rotation accuracy can meet the precise angle requirements of different welding positions, ensuring that each welding point of the stator body 27 is in a position that is convenient for welding.

[0036] like Figures 3-5 As shown, a clamping assembly 3 is installed on the upper part of the processing table 11. The function of the clamping assembly 3 is to firmly fix the stator body 27, prevent displacement during welding, and ensure welding accuracy. The clamping assembly 3 includes support rods 31 fixedly installed at the four corners of the upper part of the processing table 11. The support rods 31 are made of high-strength metal material and are fixed to the processing table 11 by welding. The welding is firm and the verticality error is small. A support plate 32 is fixedly installed at one end of each support rod 31. The support plate 32 is connected to the support rod 31 by full welding. The welding surface is large and firm, which can stably support the other parts of the clamping assembly 3. A cylinder 33 is installed on the support plate 32 by multiple bolts. The bolts are evenly distributed to ensure that the cylinder 33 is firmly installed. The cylinder 33 is a standard cylinder with a stable air supply. The output force can be controlled by adjusting the air pressure.

[0037] The output end of the cylinder 33 is bolted to an intermediate plate 34. The intermediate plate 34 is made of a material with good rigidity and is not easily deformed. A clamping seat 35 adapted to the stator body 27 is bolted to the lower part of the intermediate plate 34. The shape of the clamping seat 35 matches the upper contour of the stator body 27 and can fit tightly with the stator body 27. A buffer pad (not shown in the figure) is pasted on the lower part of the clamping seat 35. The buffer pad has a certain elasticity and wear resistance, which can ensure the clamping effect and prevent the stator body 27 from moving.

[0038] Once the stator body 27 is adjusted to a suitable height and angle by the lifting assembly 2, the control system sends a signal to start the cylinder 33. Compressed air is introduced into the rodless chamber of the cylinder 33. Under the action of air pressure, the piston rod extends and pushes the intermediate plate 34 downward. The intermediate plate 34 drives the clamping seat 35 fixed at its lower part to descend synchronously until the buffer pad at the lower part of the clamping seat 35 is in close contact with the surface of the stator body 27. At this time, the cylinder 33 outputs stable pressure to firmly fix the stator body 27 on the holder 26, preventing the stator body 27 from shifting due to the impact of the welding arc, equipment vibration, etc. during the welding process, ensuring the accurate relative position of each welding point, and guaranteeing welding precision and welding quality.

[0039] like Figure 3 and Figure 5 As shown, a fumigation assembly 4 is installed on the intermediate plate 34. The function of the fumigation assembly 4 is to collect and purify the fumes and harmful gases generated during welding, ensuring a clean working environment. The fumigation assembly 4 includes a fumigation pipe 41 installed on the upper part of the intermediate plate 34, and multiple fumigation nozzles 42 connected to the fumigation pipe 41 are installed in the lower part of the intermediate plate 34 by threaded connection. The multiple fumigation nozzles 42 are evenly distributed in the lower part of the intermediate plate 34, which can cover the welding area of ​​the stator body 27, ensuring that the fumes generated at each welding point can be effectively collected.

[0040] A fan 43 is bolted to one side of the upper part of the welding box 1. The fan 43 is a centrifugal fan with large air volume and high air pressure, which can form a strong negative pressure in the smoke extraction assembly 4. Gas treatment boxes 44 are bolted to both sides of the support plate 32. The gas treatment box 44 adopts a sealed structure design to prevent the leakage of harmful gases during the treatment process. Its interior is equipped with a multi-layer filtration and purification structure (not shown in the figure), including a primary filter layer for filtering large particulate smoke, an adsorption layer for adsorbing harmful gases, and a high-efficiency filter layer for filtering fine particulate matter. The filtration efficiency is high and it can effectively purify various pollutants generated by welding.

[0041] A negative pressure pipe 45 is connected to the air intake of the fan 43 via a flange. The flange connection has good sealing performance. One end of the negative pressure pipe 45 passes through the welded housing 1 and is connected to the front end of the gas treatment box 44. A corrugated pipe 46 is connected to the rear end of the gas treatment box 44 via a connector. The corrugated pipe 46 has good flexibility and can freely expand and contract with the rise and fall of the intermediate plate 34 without affecting the movement of the intermediate plate 34. One end of the corrugated pipe 46 passes through the support plate 32 and is connected to the smoke extraction pipe 41 to ensure the sealing of the entire smoke extraction path and reduce smoke leakage.

[0042] During welding operations, the blower 43 is powered on in advance. Under its action, a negative pressure is first formed in the negative pressure pipe 45. This negative pressure is transmitted to the bellows 46 through the gas treatment box 44, which in turn causes the smoke pipe 41 and the smoke mouth 42 to generate negative pressure in sequence, forming a complete negative pressure smoke path. A large amount of smoke and harmful gases generated during the welding process will be sucked into the smoke mouth 42 under the action of strong negative pressure.

[0043] The smoke then enters the corrugated pipe 46 through the smoke extraction pipe 41, and is then transported to the gas treatment box 44 through the corrugated pipe 46. Inside the gas treatment box 44, the smoke and harmful gases undergo multi-layer filtration and purification. Large smoke particles are intercepted by the primary filter layer, harmful gases are adsorbed by the adsorption layer, and fine particulate matter is filtered by the high-efficiency filter layer. The purified gas then enters the fan 43 through the negative pressure pipe 45, and is finally discharged into the atmosphere by the fan 43. This ensures that the concentration of smoke and harmful gases in the working environment is controlled at a low level, protecting the health of operators, and preventing smoke from adhering to the equipment surface and affecting the equipment's performance and service life.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
