[0009] Preferably, one side of the magnetic block is fixedly connected to one side of the opening and closing flip plate, the outer wall of the magnetic block is in contact with the outer wall of the sliding plate, and the magnetic block and the sliding plate are magnetic.

[0010] Preferably, the magnetism of the magnetic block and the sliding plate on the side close to each other is that opposite poles attract each other, the outer wall of the sliding plate is fixedly connected to a connecting long plate, one side of the connecting long plate is fixedly connected to bristles, and the bristles have elastic force.

[0011] Preferably, the length of the bristles can extend into the inner wall of the shielding cover, and one side of the opening and closing flip plate is fixedly connected to a limit baffle, which is used to limit the sliding of the sliding plate and prevent the sliding plate from slipping off the closing and closing flip plate.

[0012] The present invention provides an arc welding machine for new energy vehicle parts, which has the following beneficial effects: 1. The present invention provides an opening and closing mechanism, through which the telescopic plate is extended and retracted and the bottom of the telescopic plate is fixed by the bottom of the inner wall of the arc welding machine, so that when the opening and closing flip plate is opened, the rubber pull rope and the fixed block are pulled up synchronously with the telescopic plate by the sliding plate, so that after the opening and closing flip plate is fully opened, the telescopic plate is also fully extended, and the inside of the arc welding machine is completely isolated from the outside, and the telescopic plate is also fitted with the baffle to form a natural closed space inside the arc welding machine, and then the opening and closing flip plate can be freely opened and closed to conveniently clean the ventilation slot, prevent the ventilation slot from being blocked to affect the heat dissipation inside the arc welding machine, and automatically close the communication channel between the arc welding machine and the outside, so as to avoid the problem of dust overflowing and being directly sucked into the arc welding machine by the exhaust of the fan during the cleaning of the ventilation slot, and also avoid the entry of dust and moisture from the outside during the cleaning; 2. The present invention sets an opening and closing mechanism, and after the cleaning is completed, the opening and closing flip plate is rotated and lowered to reset, and the sliding plate, rubber pull rope, fixed block and telescopic plate are also lowered and reset, so that after the opening and closing flip plate is closed, the telescopic plate actively descends to open the connecting channel between the arc welding machine and the outside, so that when the opening and closing flip plate is closed, the ventilation slot is naturally utilized to realize the internal and external connection, ventilation and heat exchange, and the operation is simple, and the above work can be realized by simply holding the shielding cover and lifting and closing the opening and closing flip plate, so that the cleaning efficiency is higher and the staff is more motivated to clean the ventilation slot, which effectively reduces the problem of low heat exchange efficiency caused by not cleaning the ventilation slot for a long time, and the high temperature damage inside the arc welding machine.

[0013] 3. The present invention provides a limiting mechanism. Every time the shielding cover needs to be opened to clean the ventilation slots, when it is pulled to a position close to ninety degrees, the bristles can be used to quickly move to automatically brush the inside of each ventilation slot. When the bristles are brushing, the telescopic plate has extended to one side of the baffle and fits with the baffle to close the connection between the arc welder and the outside. While automatically cleaning the ventilation slots, it also naturally avoids the problem of a large amount of dust generated by brushing during automatic cleaning and being sucked into the interior of the arc welder.

[0014] 4. The present invention sets a limit mechanism and also utilizes the rapid brushing method to effectively enhance the cleaning force inside the ventilation slot, and can complete the automatic cleaning effect of the sliding plate, the connecting long plate and the brush by repeatedly opening and closing the flip plate, so that the cleaning work inside the arc welding machine can be completed without polluting the inside of the arc welding machine by manually carrying cleaning tools.

[0015] 5. The present invention sets a limit mechanism, so that the opening and closing flip plate can be reciprocated to complete the reciprocating lifting and lowering of the sliding plate, and the ventilation slots can be cleaned by using the bristles. When the opening and closing flip plate automatically cleans the ventilation slots, the centrifugal inertia formed by the opening and closing flip plate will be used to naturally throw out the residue in the ventilation slot after being brushed by the bristles, and the centrifugal force of the residue is easier to break away from the adhesion, which also improves the cleaning effect. The air flow formed by the opening and closing flip plate fanning the air will take away the swept particles in the direction of the air flow, and then keep them away from the position of the arc welding machine, reducing the problem of being sucked into it again after closing the opening and closing flip plate; 6. The present invention provides a limiting mechanism, and when the telescopic plate is on its way of automatically descending and resetting, the telescopic plates will push down the dust attached to the outer wall one by one when they retract, and the dust will fall into the area between the opening and closing flip plate and the telescopic plate and be blocked by the telescopic plate to prevent the dust from entering the arc welding machine. When the opening and closing flip plate is subsequently opened, the dust between the telescopic plate and the opening and closing flip plate can be cleaned. The self-cleaning of the telescopic plate when it retracts and the blocking of the dust by the telescopic plate can effectively avoid the problem of dust drifting into the interior of the arc welding machine after the telescopic plate is reset.

DETAILED DESCRIPTION

[0018] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: an arc welding machine for new energy vehicle parts, comprising an arc welding machine 2, a lifting handle 1 is fixedly connected to the top of the arc welding machine 2, a connection port 5 is arranged on one side of the arc welding machine 2, a plug 6 is fixedly connected to the outer wall of the arc welding machine 2, a fan 7 is arranged inside the arc welding machine 2, and an opening and closing mechanism 3 is arranged on the left side of the arc welding machine 2; The opening and closing mechanism 3 comprises: The opening and closing flip plate 301 is a square plate structure. A shielding cover 302 is fixedly connected to one side of the opening and closing flip plate 301. A ventilation slot 307 is provided inside the opening and closing flip plate 301. The inside of the ventilation slot 307 is connected to the inside of the shielding cover 302. The opening and closing flip plate 301 is used to isolate the inside of the arc welding machine 2 from the outside. The connecting rod 304 is L-shaped, one end of the connecting rod 304 is fixedly connected to one side of the opening and closing flip plate 301, the inner wall of the connecting rod 304 is fixedly connected with a rotating shaft 305, the outer wall of the rotating shaft 305 is rotatably connected with a hinge block 303, one end of the hinge block 303 is fixedly connected to one side of the arc welding machine 2, the rotating shaft 305 is used to connect the connecting rod 304 and the hinge block 303 and play a role in allowing the two to rotate relative to each other, and the connecting rod 304 is used to play the role of connecting the opening and closing flip plate 301 and the rotating shaft 305.

[0019] When in use, plug the connection line into the connection port 5, then insert the plug 6 on the arc welder 2 into the socket, then start the arc welder 2, and use the current generated by it to perform electric welding work on the parts related to the new energy vehicle. When welding the parts, the fan 7 in the arc welder 2 discharges the air in the arc welder 2 to the outside, and the external air is sucked through the ventilation slots 307 in the opening and closing flip plate 301 on the other side, and the air is sucked into the arc welder 2. At the same time, the several shielding covers 302 on the outer wall of the opening and closing flip plate 301 prevent the splashing of particles and rainwater, and the several slender ventilation slots 307 are also used to filter large particles of dust; Example 2: Please refer to Figure 1-10 On the basis of the first embodiment, the present invention provides a technical solution: the outer wall of the opening and closing flip plate 301 is fixedly connected with a sliding bar 308, and the outer wall of the sliding bar 308 is slidably connected with a sliding plate 309. The sliding plate 309 is slidably connected to the opening and closing flip plate 301 through the sliding bar 308. The sliding bar 308 is used to allow the sliding plate 309 to slide on the outer wall of the opening and closing flip plate 301 and prevent the sliding plate 309 from falling off the outer wall of the opening and closing flip plate 301.

[0020] A rubber pull rope 310 is fixedly connected to the outer wall of the sliding plate 309 , and the other end of the rubber pull rope 310 is fixedly connected to a fixing block 311 . The rubber pull rope 310 is elastic, and a baffle 313 is fixedly connected to the top of the inner wall of the arc welding machine 2 .

[0021] A telescopic plate 312 is fixedly connected to the bottom of the fixed block 311 , and two sides of the telescopic plate 312 are slidably connected to two sides of the inner wall of the arc welding machine 2 , and the bottom of the telescopic plate 312 is fixedly connected to the bottom of the inner wall of the arc welding machine 2 .

[0022] After the arc welding machine 2 has been working for a long time, when particles appear in the ventilation slot 307 and stains adhere to the inside due to high air humidity, the shielding cover 302 at the bottom of the opening and closing flip plate 301 can be buckled and lifted up, so that the shielding cover 302 and the opening and closing flip plate 301 are lifted synchronously, and when the opening and closing flip plate 301 is lifted, the connecting rod 304 and the rotating shaft 305 are driven to rotate synchronously, and the rotating shaft 305 rotates on the inner wall of the hinge block 303, so that the opening and closing flip plate 301 and the shielding cover 302 are centered on the rotating shaft 305. The opening and closing flip plate 301 is opened and closed by rotating the center of the circle, and the ventilation slot 307 on the inner side of the opening and closing flip plate 301 is exposed after the opening and closing flip plate 301 is lifted, and then the stains blocked in the ventilation slot 307 are cleaned. At the same time, when the shielding cover 302 is pulled to lift the opening and closing flip plate 301, the opening and closing flip plate 301 will pull the rubber pull rope 310 through the sliding plate 309, and as the opening and closing flip plate 301 and the sliding plate 309 are lifted and opened, the end of the rubber pull rope 310 connected to the sliding plate 309 will begin to rise, and the rubber pull rope 310 will be pulled. The fixing block 311 is naturally pulled by its own elastic force, and the fixing block 311 drives the telescopic plate 312 to slide and rise along the two sides of the inner wall of the arc welding machine 2. The telescopic plate 312 is extended and the bottom of the telescopic plate 312 is fixed by the bottom of the inner wall of the arc welding machine 2, so that when the opening and closing flip plate 301 is opened, the sliding plate 309 is used to pull the rubber pull rope 310 and the fixing block 311 and the telescopic plate 312 to rise synchronously, so that after the opening and closing flip plate 301 is fully opened, the telescopic plate 312 is also fully extended, and the arc welding machine 2 is closed. The interior of the arc welding machine 2 is completely isolated from the outside, and the telescopic plate 312 is also fitted with the baffle plate 313 to form a naturally enclosed space inside the arc welding machine 2, so that the opening and closing flip plate 301 can be freely opened and closed to conveniently clean the ventilation slot 307, thereby preventing the ventilation slot 307 from being blocked and affecting the internal heat dissipation of the arc welding machine 2, and automatically closing the communication channel between the arc welding machine 2 and the outside, thereby avoiding the problem of dust overflowing and being directly sucked into the interior of the arc welding machine 2 by the exhaust of the fan 7 during the cleaning of the ventilation slot 307, and also avoiding the entry of dust and moisture from the outside during the cleaning period; After the cleaning is completed, the opening and closing flip plate 301 is rotated and lowered to reset, and the sliding plate 309, the rubber pull rope 310, the fixed block 311, and the telescopic plate 312 are also lowered and reset, so that after the opening and closing flip plate 301 is closed, the telescopic plate 312 actively descends to open the communication channel between the arc welding machine 2 and the outside, so that when the opening and closing flip plate 301 is closed, the ventilation slot 307 is naturally used to realize the internal and external communication ventilation and heat exchange work, and the operation is simple, and the above work can be realized by simply holding the shielding cover 302 and lifting and closing the opening and closing flip plate 301, so that the cleaning efficiency is higher and the staff is more motivated to clean the ventilation slot 307, which effectively reduces the low heat exchange efficiency caused by not cleaning the ventilation slot 307 for a long time, and the problem of high temperature damage inside the arc welding machine 2; Example 3: Please refer to Figure 1-13 On the basis of the first and second embodiments, the present invention provides a technical solution: the groove on the inner wall of the shielding cover 302 is in an arc shape tilted downward, and a limiting mechanism 4 is provided on the outer wall of the opening and closing flip plate 301, and the limiting mechanism 4 includes a magnetic block 401.

[0023] One side of the magnetic block 401 is fixedly connected to one side of the opening and closing flip plate 301 , and the outer wall of the magnetic block 401 contacts the outer wall of the sliding plate 309 , and the magnetic block 401 and the sliding plate 309 are magnetic.

[0024] The magnetism of the magnetic block 401 and the sliding plate 309 on the side close to each other is that opposite poles attract each other. The outer wall of the sliding plate 309 is fixedly connected to a connecting long plate 402, and one side of the connecting long plate 402 is fixedly connected to bristles 403, and the bristles 403 have elastic force.

[0025] The bristles 403 are long enough to extend into the inner wall of the shielding cover 302 . A limit baffle 404 is fixedly connected to one side of the opening and closing flip plate 301 . The limit baffle 404 is used to limit the sliding of the sliding plate 309 and prevent the sliding plate 309 from slipping off the closing and flip plate 301 .

[0026] When the opening and closing flip plate 301 is turned up, the sliding plate 309 maintains a stable magnetic attraction through the magnetic attraction between the opposite poles of the magnetic block 401, so that the rubber pull rope 310 can be pulled to bring the fixed block 311 and the telescopic plate 312 up together. At the same time, the sliding plate 309 will gradually rise and begin to move away from the fixed block 311 and the telescopic plate 312. At this time, the rubber pull rope 310 will be stretched and deformed until the opening and closing flip plate 301 is opened and closed to nearly 90 degrees. At this time, the rubber pull rope 310 pulls the fixed block 311 and the telescopic plate 312 to move upward. When the opening and closing flip plate 301 is close to the horizontal position, the pulling force of the rubber pull rope 310 is the largest, so the elastic force of the rubber pull rope 310 will still pull the sliding plate 309. The elastic force at this time is greater than the magnetic attraction between the sliding plate 309 and the magnetic block 401, so that the sliding plate 309 is separated from the magnetic attraction relationship between the magnetic block 401 and is quickly pulled by the resilience of the rubber pull rope 310, so that the sliding plate 309 quickly slides on the sliding bar 308 and approaches the fixed block 311 at this time, realizing the passage from the bottom of the opening and closing flip plate 301. The air slot 307 is quickly slid to the uppermost air slot 307 position, and when the sliding plate 309 slides, the bristles 403 connected to one side of the long plate 402 are driven to continuously extend into each air slot 307 to complete the cleaning of each air slot 307. Then, each time the air slot 307 needs to be opened for cleaning, when it is pulled to a position close to ninety degrees, the bristles 403 can be used to quickly move to automatically brush the inside of each air slot 307, and when the bristles 403 are brushing, the telescopic plate 312 has By extending into one side of the baffle plate 313 and fitting with the baffle plate 313 to close the communication channel between the arc welding machine 2 and the outside, the problem of a large amount of dust being generated by brushing and being sucked into the interior of the arc welding machine 2 is naturally avoided. Similarly, the rapid brushing in this manner is also used to effectively improve the cleaning force inside the ventilation slot 307. The automatic cleaning effect of the sliding plate 309, the connecting long plate 402, and the brush 403 can be completed by repeatedly opening and closing the flip plate 301, and the cleaning work without polluting the interior of the arc welding machine 2 can be completed without manually carrying cleaning tools. After the sliding plate 309 is separated from the magnetic block 401 and quickly slides to the other side of the opening and closing flip plate 301, the opening and closing flip plate 301 is reset by closing the opening and closing flip plate 301. Then, the sliding plate 309 and the telescopic plate 312 naturally drop to their original positions due to gravity, and the sliding plate 309 is magnetically attracted to the bristles 403 below again, so that the opening and closing flip plate 301 can be opened and closed reciprocally, and the bristles 403 are used to clean the ventilation slots 307 when the sliding plate 309 is lifted and lowered. When the ventilation slot 307 is automatically cleaned, the centrifugal inertia formed by the opening and closing flip plate 301 will be used to naturally throw out the residue in the ventilation slot 307 after being brushed by the bristles 403, and the centrifugal force will make it easier for the residue to break away from the adhesion, which will also improve the cleaning effect. The air flow formed by the opening and closing flip plate 301 fanning the air will take the swept particles away in the direction of the air flow, and then keep them away from the position of the arc welding machine 2, reducing the problem of being sucked into it again after closing the opening and closing flip plate 301. When the telescopic plate 312 descends and resets itself, the telescopic plates 312 will push down the dust attached to the outer wall one by one when they retract, and the dust will fall into the area between the opening and closing flip plate 301 and the telescopic plate 312, and will be blocked by the telescopic plate 312 to prevent the dust from entering the arc welding machine 2. When the opening and closing flip plate 301 is subsequently opened, the dust between the telescopic plate 312 and the opening and closing flip plate 301 can be cleaned. The self-cleaning of the telescopic plate 312 when it retracts and the blocking of the telescopic plate 312 against the dust can effectively avoid the problem of dust drifting into the interior of the arc welding machine 2 after the telescopic plate 312 is reset.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
