By moving the welding output device 15, the welding output device 15 can adapt to shielding covers of different sizes, thereby making the device more applicable.

[0027] like Figure 2 and Figure 3As shown, a positioning and clamping fixture device 2 is installed on the top of the processing plate 12; a smoke exhaust port 21 is installed on the side of the positioning and clamping fixture device 2; a fixing component 22 is installed in the middle of the smoke exhaust port 21; the end of the fixing component 22 is fixedly connected to the side wall of the positioning and clamping fixture device 2; a positioning base 23 is installed on the top of the processing plate 12; the positioning base 23 is directly opposite to the bottom of the positioning and clamping fixture device 2; the positioning and clamping fixture device 2 is located on the side of the Z-axis adjustment device 14. When working, the shielding cover can be transmitted to the bottom of the welding output device 15 through other devices on the top of the protective cover 1, so as to perform welding operation on the shielding cover. At this time, when the shielding cover is transmitted to the bottom of the welding output device 15, it will And it contacts with the positioning and pressing jig device 2. When the shielding cover contacts with the positioning and pressing jig device 2, the positioning and pressing jig device 2 can fix the shielding cover. After the fixing is completed, the shielding cover can be welded. At the same time, when the welding is completed, the positioning and pressing jig device 2 can press the shielding cover. At this time, the exhaust gas generated by the welding will be discharged through the smoke exhaust port 21, thereby released to the outside of the equipment. Through the above structure, on the one hand, the exhaust gas generated by the welding can be uniformly discharged and treated, reducing the pollution to the environment caused by the exhaust gas being discharged to the outdoors. On the other hand, the shielding cover can be clamped and positioned, so as to realize the fixation of the shielding cover. At the same time, the shielding cover can be pressed and tested to test the welding strength of the shielding cover.

[0028] like Figure 5 As shown, a slot 3 is provided in the middle of the welding output device 15; a block 31 is detachably installed in the middle of the slot 3; a support plate 32 is fixedly connected to the middle of the block 31; a corrugated sleeve 33 is fixedly connected to the bottom of the support plate 32. When working, the block 31 is installed inside the slot 3. At this time, as the Z-axis adjustment device 14 is started, the welding output device 15 will perform synchronous Z-axis movement. At this time, as the welding output device 15 moves, the corrugated sleeve 33 at the bottom of the support plate 32 will also move synchronously. When the corrugated sleeve When the bottom of 33 contacts the top of the processing plate 12, the corrugated sleeve 33 will shrink. At this time, as the corrugated sleeve 33 shrinks, the welding output device 15 is located inside the corrugated sleeve 33.

When working, the lubricating liquid is filled in the water tank 41, and then the water pump in the water tank 41 is started. As the water pump is started, the lubricating liquid in the water tank 41 will be filled into the water pipe 42. Then, as the water pump continues to start, the lubricating liquid in the water pipe 42 will flow to the end of the water pipe 42, pass through the conical cylinder 43, and then spray out. At this time, the sprayed lubricating liquid will be guided by the conical cylinder 43 and sprayed toward the side wall of the Z-axis adjustment device 14.

At this time, the moving connecting rod 51 will synchronously drive the sliding ring 5 to slide in the middle of the water pipe 42. At this time, by setting the sliding ring 5, the water pipe 42 can be limited and fixed. Through the above structure, the vibration of the water pipe 42 for a long time as the water pump is started is reduced, which eventually leads to the occurrence of falling off.

When the shielding cover contacts the positioning and pressing fixture device 2, the positioning and pressing fixture device 2 can fix the shielding cover. After the fixing is completed, the shielding cover can be welded. At the same time, when the welding is completed, the positioning and pressing fixture device 2 can press the shielding cover. At this time, the exhaust gas generated by the welding will be discharged through the smoke exhaust port 21, thereby released to the outside of the equipment, and the card block 31 will be installed in the card slot 3. At this time, with the start-up of the Z-axis adjustment device 14, the welding output device 15 will perform synchronous Z-axis movement. At this time As the welding output device 15 moves, the corrugated sleeve 33 at the bottom of the support plate 32 will also move synchronously. When the bottom of the corrugated sleeve 33 contacts the top of the processing plate 12, the corrugated sleeve 33 will shrink. At this time, as the corrugated sleeve 33 shrinks, the welding output device 15 is located inside the corrugated sleeve 33. At this time, the shielding cover will be welded inside the corrugated sleeve 33, and the lubricating liquid is filled in the water tank 41. Then, the water pump inside the water tank 41 is started. As the water pump is started, the lubricating liquid inside the water tank 41 will fill the inside of the water pipe 42. Then, as the water pump continues to start, the lubricating liquid inside the water pipe 42 will flow to the end of the water pipe 42 and pass through the conical cylinder 41. 3, and then it is sprayed out. At this time, the sprayed lubricating liquid will be guided by the conical cylinder 43 and sprayed toward the side wall of the Z-axis adjusting device 14. As the Z-axis adjusting device 14 slides, the connecting rod 51 on the side wall of the Z-axis adjusting device 14 moves synchronously. At this time, the moving connecting rod 51 will synchronously drive the sliding ring 5 to slide in the middle of the water pipe 42. At this time, by setting the sliding ring 5, the water pipe 42 can be limited and fixed. The baffle 6 is installed on the top of the bottom plate 13. At this time, the lubricating liquid is sprayed out from the inside of the conical cylinder 43 and sprayed toward the side wall of the Z-axis adjusting device 14. At this time, by setting the baffle 6, the excess lubricating liquid dripping along the side wall of the Z-axis adjusting device 14 can be collected and blocked.
