[0014] (III) Beneficial effects

[0015] 1. The limit plate is driven downward by moving the connecting seat downward, so that the distance between the limit plate and the base plate is less than the length of the vertical pole. At this time, the four vertical poles are respectively inserted from the limit holes, which plays a limit role in the placement of the four vertical poles. At this time, the bottom ends of the four vertical poles are accurately placed on the upper end of the base plate. The staff can weld the vertical poles to the base plate through a welding gun, and then the plywood conveying metal frame can be welded.

[0017] 3.

A U-shaped placing plate 8 is installed on the welding table 1, and the bottom end of the U-shaped placing plate 8 is fixedly connected to a connecting shaft 81, and the connecting shaft 81 is rotatably connected to the welding table 1.The connecting shaft 81 and the output shaft 1 of the servo motor 1 51 are on the same center of a circle, and the bottom plate 91 is placed on the U-shaped placement plate 8. When welding the metal frame assembly 9, the bottom plate 91 is placed in the U-shaped placement plate 8, and then the servo motor 2 63 is started to rotate the screw rod 2, and the rotation of the screw rod 2 drives the slide bar 61 to move, and the movement of the slide bar 61 drives the triangle block 2 64 to move, and the movement of the triangle block 2 64 will exert a force on the triangle block 1 53, so that the triangle block 1 53 moves downward, and the downward movement of the triangle block 1 53 drives the connecting seat 5 to move downward, and the downward movement of the connecting seat 5 drives the limit plate 2 to move downward, so that the distance between the limit plate 2 and the bottom plate 91 is less than the length of the vertical rod 92.

A spring 1 43 is fixedly connected between the fixed plate 41 and the through rod 42, which plays a role in limiting the fixed plate 41 and the rack 4. The structure design is reasonable.

[0032] Working principle:

[0033] In the first step, when welding the metal frame assembly 9, the bottom plate 91 is placed in the U-shaped placement plate 8, and then the servo motor 2 63 is started to rotate the screw rod 2, and the rotation of the screw rod 2 drives the slide bar 61 to move, and the movement of the slide bar 61 drives the triangle block 2 64 to move, and the movement of the triangle block 2 64 will exert a force on the triangle block 1 53, so that the triangle block 1 53 moves downward, and the downward movement of the triangle block 1 53 drives the connecting seat 5 to move downward, and the downward movement of the connecting seat 5 drives the limit plate 2 to move downward, so that the distance between the limit plate 2 and the bottom plate 91 is less than the length of the vertical rod 92. At this time, the four vertical rods 92 are respectively inserted from the limiting holes 21, which plays a limiting role in the placement of the four vertical rods 92. At this time, the bottom ends of the four vertical rods 92 are accurately placed on the upper end of the bottom plate 91. The staff can weld the vertical rods 92 to the bottom plate 91 through the welding gun 12, and the plywood conveying metal frame can be welded. The welding machine tool ensures that the vertical rods 92 can be accurately welded to the bottom plate 91 by limiting the positions of the four vertical rods 92, and the staff does not need to hold the vertical rods 92 by hand, making it more convenient to weld the metal frame, which provides convenience for the staff during the welding process;

[0034] In the second step, when the triangular block 2 64 moves and is completely misaligned with the triangular block 1 53, the screw rod 2 continues to rotate, and the triangular block 2 64 continues to move. At this time, the triangular block 2 64 has moved to the straight rod 54. With the support of the spring 2 72, the triangular block 2 64 continues to move and no longer exerts a downward force on the connecting seat 5, so that the position of the limit plate 2 remains in the original downward state, that is, the limit plate 2 will not continue to move downward. The continued movement of the triangular block 2 64 causes the push rod 65 to push the fixed plate 41 to move, and the movement of the fixed plate 41 drives the rack 4 to move, and the movement of the rack 4 drives the gear 24 to rotate, and the rotation of the gear 24 The screw rod 1 23 is driven to rotate, and the rotation of the screw rod 1 23 drives the two sliders 31 to move away from each other, and the two sliders 31 move away from each other, so that the two abutment plates 3 abut against the upper ends of the four vertical rods 92, that is, when the triangular block 2 64 continues to move, the two abutment plates 3 can be driven to abut against the four vertical rods 92, and the four vertical rods 92 are limited and locked, so that in the process of welding the vertical rods 92 to the bottom plate 91, the vertical rods 92 are prevented from being offset (in the vertical direction), which makes it more convenient for the staff to weld the vertical rods 92 to the bottom plate 91, ensures the convenience and quality of welding, and improves the welding efficiency of the metal frame;

[0035] The third step is to start the servo motor 51 after the welding of the two vertical poles 92 on one side is completed. At this time, the vertical poles 92 and the bottom plate 91 have been welded and fixed. The limit plate 2 is rotated with the connecting shaft 81 as the axis. The rotation of the limit plate 2 drives the two vertical poles 92 on one side to rotate, so that the bottom plate 91 is rotated, so that the two unwelded vertical poles 92 are rotated to the same side as the welding gun 12. At this time, the two unwelded vertical poles 92 can be welded to the bottom plate 91. At this point, all welding work on the four vertical poles 92 is completed. There is no need for the staff to move the welding gun 12 to the other side of the welding table 1, which improves the flexibility of the welding machine tool, makes it more convenient for the staff to perform welding operations, and improves the welding efficiency.

[0036] Step 4: Four fixed rods 25 are fixedly installed at equal intervals on the upper circumference of the limit plate 2. Each fixed rod 25 is fixedly connected with a connecting block 26. Each connecting block 26 is slidably installed in the annular groove 52, which plays a role in reinforcing support and limiting the connection between the limit plate 2 and the output shaft of the servo motor 51, ensuring the stable operation of the welding operation and reasonable structural design.

[0037] The fifth step is to fix each connecting rod 71 with the connecting seat 5, and a spring 2 72 is fixedly connected between each connecting rod 71 and each cylinder 7. The spring 2 72 is used to support and reset the limit plate 2. The through-rod 42 movably penetrates the fixed plate 41, which limits the movement of the rack 4 and the fixed plate 41, prevents the rack 4 from lateral position deviation, ensures the stable movement of the rack 4, and thus ensures the stable operation of the clamping assembly. A spring 1 43 is fixedly connected between the fixed plate 41 and the through-rod 42, which limits the fixed plate 41 and the rack 4, and the structural design is reasonable.

[0038] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
