At this time, under the rotation of the handle 181, the second top plate 182 will approach the forklift frame and clamp the frame. At this time, the staff will turn on the electric cylinder 14 to make the electric cylinder 14 work, and the electric cylinder 14 will push the first top plate 16 to rise and fall. At this time, through the connection between the second top plate 182 and the synchronization rod 19, the slide rod 171 will also rise and fall with the frame, so that the forklift frame can be initially welded, which reduces the problem of increasing the welding time due to adjusting the position of the forklift during welding, and reduces the production time of the forklift frame welding.

[0027] Further, such as Figures 1 to 3As shown, the top of the protective cover 15 is symmetrically provided with multiple groups of push plates 2; the push plates 2 are bolted to the adjacent push plates 2, and the side walls of the push plates 2 are symmetrically fixed with rubber strips 21; the rubber strips 21 are in contact with the output end of the electric cylinder 14, and the side walls of the protective cover 15 are symmetrically fixed with support seats 22; the top of the support seats 22 are arranged in an array and fixed with multiple groups of telescopic rods 23; the ends of the telescopic rods 23 are fixed with a second support plate 24; the push plates 2 are in contact with the second support plates 24, and the push plates 2 are located at the bottom of the second support plates 24; when working, when the welding of the fixed part of the forklift is completed, the second top plate 182 is moved by rotating the handle 181 Away from the forklift frame, place the supporting frame and the connecting fixing plate that need to be welded on the top of the second supporting plate 24, then rotate the handle 181 to make the second top plate 182 push the component to contact the frame, then turn on the electric cylinder 14 to make the electric cylinder 14 work, then the electric cylinder 14 will drive the push plate 2 to move up and down, and the friction force of the rubber strip 21 will make the push plate 2 push the second supporting plate 24 to rise, and under the guidance of the telescopic rod 23, the component is supported and lifted to the specified position, and then welded by a welding machine, which increases the support for welding between the component and the frame and reduces the problem of adjusting the position and increasing the welding time when welding components.

[0028] Further, such as Figure 2 and Figure 4 As shown, the first top plate 16 is symmetrically hinged with a first rotating shaft 3 on the top; the first rotating shaft 3 is hinged with a second rotating shaft 31 on the top; a first retractable rod 32 is fixedly connected to the surface of the first rotating shaft 3; a second retractable rod 33 is hinged on the surface of the second rotating shaft 31; the first retractable rod 32 is rotatably connected to a fixed support 34 at one end away from the first rotating shaft 3; the second retractable rod 33 is rotatably connected to a fixed support 34 at one end away from the second rotating shaft 31; the fixed support 34 is L-shaped; when working, the skeleton is placed on the top of the first top plate 16 for initial operation. During welding, the fixed support 34 is pulled to squeeze the first retractable rod 32 and the second retractable rod 33. After the skeleton is placed, the fixed support 34 is loosened to allow the first rotating shaft 3 and the second rotating shaft 31 to reset the first retractable rod 32 and the second retractable rod 33 under the action of the torsion spring. At this time, the fixed support 34 will slide on the surface of the first top plate 16 and contact the skeleton, so that the fixed support 34 fixes the skeleton, which increases the stability of the skeleton during welding, reduces the shaking of the skeleton when adjusting its position during welding, and reduces the welding time of the skeleton.

[0029] Further, such as Figure 2 and Figure 4As shown, the top of the first top plate 16 is symmetrically provided with a slide groove 4; a first pressing block 41 is slidably connected in the slide groove 4; a second pressing block 42 is slidably connected in the slide groove 4; a connecting plate 43 is fixedly connected between the first pressing block 41 and the second pressing block 42; the connecting plate 43 and the slide groove 4 are slidably connected; a spring 44 is fixedly connected between the connecting plate 43 and the slide groove 4; when working, before welding the frame, by pressing the first pressing block 41 and the second pressing block 42 and then sliding the fixing support 3 4, so that the fixing support 34 and the second pressing block 42 are engaged with each other. At this time, when the frame is placed on the top of the first top plate 16, the connection of the frame will squeeze the first pressing block 41 to make the first pressing block 41 and the second pressing block 42 slide. When the second pressing block 42 slides, the fixing support 34 will pop out under the action of the torsion spring hinged between the first rotating shaft 3 and the second rotating shaft 31, so that the fixing support 34 contacts with the frame, which reduces the time for the fixing support 34 to fix and support the frame, and increases the fluidity between the structures.

[0030] Further, such as Figure 4 As shown, the side wall of the fixed support 34 is fixedly connected to the mounting plate 5; the side wall of the mounting plate 5 is symmetrically fixedly connected to multiple groups of suction cups 51; when working, the fixed support 34 contacts the frame to firmly support the frame during welding, and through the contact between the fixed support 34 and the frame, the air in the suction cup 51 will be squeezed out by the fixed support 34, so that the suction cup 51 and the frame are more closely fitted, thereby increasing the fit between the fixed support 34 and the frame, and making the frame more stable when being raised or lowered.

[0031] Further, such as Figure 5 As shown, the side wall of the second top plate 182 is fixedly connected with a friction pad 6; when working, the handle 181 is rotated to make the screw 18 push the second top plate 182 to fix and support the skeleton or components, and the friction pad 6 fixed to the side wall of the second top plate 182 makes the skeleton and the components contact with the friction pad 6, thereby increasing the friction force during contact and increasing the stability of the structure during lifting and lowering.

[0032] Further, such as Figure 5 As shown, the surface of the handle 181 is fixedly connected with a plurality of groups of anti-skid grooves 7; the anti-skid grooves 7 are arranged in an array; during operation, when the handle 181 is rotated to make the screw 18 push the second top plate 182 to contact the skeleton or components, the anti-skid grooves 7 on the surface of the handle 181 increase the friction force when the handle 181 is rotated, thereby reducing the problem of increased adjustment time due to the smooth surface of the handle 181.

[0033] During operation, when the forklift frame is transported by the lifting robot, the frame is placed on the top of the first top plate 16, and the screw 18 is rotated by turning the handle 181. At this time, the second top plate 182 will be close to the forklift frame and clamp the frame under the rotation of the handle 181. At this time, the staff will turn on the electric cylinder 14 to make the electric cylinder 14 work, and the electric cylinder 14 will push the first top plate 16 to rise and fall. At this time, through the connection between the second top plate 182 and the synchronization rod 19, the sliding rod 171 will also rise and fall with the frame, so that the forklift frame can be initially welded, which reduces the problem of increasing the welding time when adjusting the position of the forklift during welding, and reduces the production time of the forklift frame welding. When the welding of the fixed part of the forklift is completed, the handle 181 is turned. The second top plate 182 is kept away from the forklift frame, and the supporting frame and the connecting fixing plate that need to be welded are placed on the top of the second supporting plate 24. At this time, the second top plate 182 is pushed to contact the frame by rotating the handle 181. At this time, the electric cylinder 14 is turned on to make the electric cylinder 14 work. At this time, the electric cylinder 14 will drive the push plate 2 to move up and down, and the friction force of the rubber strip 21 makes the push plate 2 push the second supporting plate 24 to move up. Under the guidance of the telescopic rod 23, the component is supported and lifted to the specified position, and then welded by a welding machine, which increases the support for welding between the component and the frame, reduces the problem of increasing the welding time by adjusting the position when welding the component, and places the frame on the top of the first top plate 16 for initial welding. The fixing support 34 is pulled to make the fixing support 34 squeeze the first contraction rod 32 and the second contraction rod 33. After the frame is placed, the fixing support 34 is loosened to make the first rotating shaft 3 and the second rotating shaft 31 reset the first contraction rod 32 and the second contraction rod 33 under the action of the torsion spring. At this time, the fixing support 34 will slide on the surface of the first top plate 16 and contact the frame, so that the fixing support 34 fixes the frame, which increases the stability of the frame during welding and reduces the shaking of the frame when adjusting its position during welding, thereby reducing the welding time of the frame. Before welding the frame, the first pressing block 41 and the second pressing block 42 are pressed and then the fixing support 34 is slid so that the fixing support 34 and the second pressing block 42 are engaged with each other. At this time, the frame is placed on the first top plate 16. When the plate 16 is at the top, the connection of the skeleton will squeeze the first pressing block 41 to make the first pressing block 41 and the second pressing block 42 slide. When the second pressing block 42 slides, the fixed support 34 will pop out under the action of the torsion spring hinged between the first rotating shaft 3 and the second rotating shaft 31, so that the fixed support 34 is in contact with the skeleton, which reduces the time for the fixed support 34 to fix and support the skeleton, and increases the fluidity between the structures. When the fixed support 34 contacts the skeleton, the skeleton is firmly supported during welding. When the fixed support 34 contacts the skeleton, the air in the suction cup 51 will be squeezed out by the fixed support 34, so that the suction cup 51 and the skeleton are more closely fitted, which increases the fit between the fixed support 34 and the skeleton, and makes the skeleton more stable when it is lifted or lowered.When the handle 181 is rotated to make the screw 18 push the second top plate 182 to fix and support the frame or component, the friction pad 6 fixed to the side wall of the second top plate 182 is used to make the frame and the component contact with the friction pad 6, which increases the friction during contact and increases the stability of the structure during lifting and lowering. When the handle 181 is rotated to make the screw 18 push the second top plate 182 to contact the frame or component, the anti-slip pattern 7 on the surface of the handle 181 increases the friction during the rotation of the handle 181, reducing the problem of the handle 181 surface being smooth and thus increasing the adjustment time.
