Once there is a local depression Automatic prompts can be achieved, allowing workers to make timely adjustments and improve welding quality. The two frame main beam cross plates are placed in slots 2011. As slots 2011 become excessively worn over time, the worn spring pieces 203 are no longer flush with the slots 2011 and protrude. When the frame main beam cross plates are inserted into slots 2011 and shaken, they are easily squeezed against the electrical connection piece 202. Simultaneously, under the pressure of the edge spring piece 205, the frame main beam cross plates will squeeze the worn spring piece 203 against the electrical connection piece 202, and the wear light strip 204 will light up as a prompt.
[0041] like Figures 4 to 10 As shown, the movable limiter 4 includes a movable slider 401 located on the welding mounting block 101; the movable slider 401 is located on the inner side of the frame main beam; four balls 402 are embedded in the bottom of the movable slider 401; the four balls 402 are respectively located on the inner sides of the frame main beam; steel brushes 403 are fixedly installed on both sides of the front end of the movable slider 401, and the two steel brushes 403 are respectively used to brush the welds of the frame main beam; a magnet 404 is fixedly embedded on the movable slider 401; the magnet 404 is used to magnetically attract the frame main beam; weld plugs 405 are respectively provided on both sides of the bottom of the movable slider 401; the two weld plugs 405 are respectively inserted into the welds of the frame main beam; the movable limiter 4 also includes a fitting switch 406 fixedly installed at the bottom of the movable slider 401, and the fitting switch 406 is attached to the surface of the frame main beam. Surface; two warning lights 407 are fixedly installed on the movable slider 401; the fitting switch 406 is electrically connected to the two warning lights 407; when the four ball bearings 402 roll to fit the main beam of the frame, the main beam of the frame squeezes the fitting switch 406, and the movable limiter 4 can be used to facilitate the staff to fit the weld for cleaning, and can be used to brush and clean possible impurities and burrs on the edge of the vertical plate of the frame main beam, thereby improving the quality of the welding molten pool, and the structure is more reasonable, which can avoid residual welds such as impurities. At the same time, the present structure utilizes the fitting switch 406 to be used to prompt the ball bearings 402 to roll and fit the vertical plate of the frame main beam, thereby ensuring the cleaning quality, and the structure is simple and fast to operate. By manually sliding the movable slider 401, the magnet 404 is used to magnetically attract the vertical plate of the frame main beam, and then the steel brush 403 can be driven to brush the weld.
[0042] like Figure 1 and Figure 9 As shown, the positioning limiter 5 includes two rows of screw mounting brackets 501 fixedly mounted on both sides of the side panel plug-in block 201 by bolts; threaded holes are respectively provided on the two rows of screw mounting brackets 501; a downward pressing screw rod 502 is threadedly connected to the screw mounting bracket 501, and a hand wheel is provided on the top of the downward pressing screw rod 502; the downward pressing screw rod 502 is aligned with the main beam of the frame; the positioning limiter 5 also includes two rows of positioning switches 503 fixedly mounted on the bottom of the two rows of screw mounting brackets 501, and the ends of the two rows of positioning switches 503 are respectively pressed and fitted to the main beam of the frame; the two rows of positioning switches 503 are electrically connected to the power supply of the welding machine, and the positioning limiter 5 can be used for clamping Holding and positioning the frame main beam cross plate can improve the welding stability of the frame main beam cross plate. At the same time, this structure uses two rows of downward pressing screw rods 502 to press down and position the frame main beam cross plate. When the welding is completed and the extrusion of the frame main beam cross plate needs to be released, the two rows of downward pressing screw rods 502 need to be rotated and disassembled separately, which takes a lot of time.

At this time, the frame main beam cross plate can be pulled out from the slot 2011.
[0043] The working principle of the present invention is as follows: first, two frame main beam cross plates are placed in the slots 2011 and shaken. As the use time increases, if the slots 2011 are excessively worn, the worn spring pieces 203 are no longer flush with the slots 2011 and will protrude. At this time, after the frame main beam cross plate is inserted into the slots 2011, it is easy to squeeze the worn spring pieces 203 to fit the power strips 202.

Fit the power connection piece 202, and the wear light strip 204 will light up to remind you. Place the vertical plate of the frame main beam on the welding mounting block 101. At this time, the two rows of downward pressure springs 103 are pressed down, driving the downward pressure springs 103 and the power connection block 102 to separate. At this time, if the vertical plate of the frame main beam is concave, some of the downward pressure springs 103 are not squeezed, and they will move up and fit the power connection block 102 on the same side to connect the power. After the two frame main beam cross plates and the frame main beam vertical plates are placed and installed, you can Manually rotate the limit screw rod 301 to drive the push plate 302 and the contact plate 303 to fit the horizontal plate of the frame main beam and the vertical plate of the frame main beam for limiting the position, manually slide the moving slider 401, and cooperate with the magnet 404 to magnetically attract the vertical plate of the frame main beam, then the steel brush 403 can be driven to brush the weld. At the same time, once the four balls 402 are separated from the vertical plate of the frame main beam due to hand shaking or sliding too fast, the steel brush 403 no longer fits the weld, and the fitting switch 406 is not squeezed. By turning on 406, the warning light 407 can be turned on to indicate that the frame main beam cross plate is inserted into the slot 2011, the two rows of downward pressing screw rods 502 can be tightened respectively to drive the positioning switch 503 to squeeze and fit the frame main beam cross plate. At this time, the welding machine power supply can be turned on and welding work can be performed normally through the welding gun. After welding is completed, the two rows of downward pressing screw rods 502 need to be rotated and moved upward so that the frame main beam cross plate no longer blocks the frame main beam cross plate. At this time, the frame main beam cross plate can be pulled out from the slot 2011 for disassembly.
