Detailed implementation manners

[0029] The present utility model will be further described below in conjunction with specific embodiments. The purpose is only to better understand the content of the present utility model. Therefore, the examples given do not limit the protection scope of the present utility model.

[0030] As Figures 1 to 5 shown, this embodiment provides an auxiliary device for welding the cross beam 5 of a vibrating screen, which includes a base platform 1. Two positioning side plates 2 are slidably connected to the base platform 1 and are locked and fixed by a locking member.

[0031] Through the plurality of groups of flange connection holes 4-2 on the flange fixing plates 4, flanges of different diameters can be connected; and the flange fixing plates 4 can be replaced according to the shape of the flange to be installed: when the cross-section of the cross beam 5 is circular, the flange fixing plates 4 can be applicable to circular flanges of different diameters; when the cross-section of the cross beam 5 is rectangular, the flange fixing plates 4 are replaced so that the flange fixing plates 4 are applicable to square flanges of different sizes; the present utility model can be applicable to the group welding work of cross beams 5 of different sizes and flanges of different sizes, and has strong versatility.

[0032] Preferably, as Figures 1 to 4 shown, the positioning side plate 2 has an L-shaped structure, which includes a bottom plate 2-3 slidably connected to the base platform 1 and a vertical plate 2-1 perpendicular to the bottom plate 2-3. The vertical plate 2-1 is located on the opposite sides of the two bottom plates 2-3; a first connection hole 2-4 is provided on the vertical plate 2-1, and a second connection hole 4-1 corresponding to the first connection hole 2-4 is provided on the flange fixing plate 4. The device further includes a connection bolt and a connection nut. The connection bolt passes through the first connection hole 2-4 and the second connection hole 4-1 and locks and fixes the positioning side plate 2 and the flange fixing plate 4 through the connection nut; in order to ensure the support effect of the vertical plate 2-1, a reinforcing rib 2-2 is provided between the bottom plate 2-3 and the vertical plate 2-1.

[0033] Preferably, as Figure 2 , Figure 6 shown, a positioning groove 1-1 is arranged along the long direction of the positioning platform on the upper edge of the positioning platform, and a positioning boss 2-5 adapted to the positioning groove 1-1 is arranged on the lower side of the bottom plate 2-3. The positioning boss 2-5 is slidably connected in the positioning groove 1-1. Among them, the side cross-section of the positioning groove 1-1 is trapezoidal or inverted T-shaped. The locking member is a locking bolt. A threaded hole 2-6 is arranged on the bottom plate 2-3, and the locking bolt is threadedly connected in the threaded hole 2-6. When the side cross-section of the positioning groove 1-1 is inverted T-shaped, the positioning boss 2-5 corresponds to an inverted T-shaped structure. When the side cross-section of the positioning groove 1-1 is trapezoidal, the positioning boss 2-5 corresponds to a trapezoidal structure. When the lower end of the locking bolt moves downward and abuts against the positioning platform, the positioning platform provides an upward reaction force, so that the positioning boss 2-5 abuts against the horizontal groove surface of the positioning groove 1-1. Since the lower bottom of the positioning boss 2-5 is large, it is clamped in the positioning groove 1-1, and the positioning side plate 2 can no longer slide along the base platform 1, and the position of the positioning side plate 2 is fixed.

[0034] Preferably, as Figure 1 shown, a support assembly 3 for supporting the cross beam 5 is arranged between the two positioning side plates 2. The support assembly 3 includes a support top plate 3-5, and the following is arranged under the support top plate 3-5; Side top seats 3-1 are arranged on the left and right sides of the support top plate 3-5. A center adjustment lead screw 3-2 is threadedly connected to the side top seat 3-1. The center adjustment lead screw 3-2 is perpendicular to the side top seat 3-1. One end of the center adjustment lead screw 3-2 is located outside the side top seat 3-1, and one end is located inside the side top seat 3-1. The end located inside the side top seat 3-1 abuts against the side surface of the cross beam 5. In this embodiment, two support assemblies 3 are placed between the two positioning side plates 2. Those skilled in the art can select to evenly lay a suitable number of support assemblies 3 between the two positioning side plates 2 according to the length of the cross beam 5.

[0035] Specifically, the height adjustment mechanism includes a bottom plate 2-3. A set of scissor folding arms 3-4 are arranged on the bottom plate 2-3, a set of two; Each scissor folding arm 3-4 includes two support rods hinged in an X shape. The ends of the support rods of the two scissor folding arms 3-4 correspond one by one and are connected by a connecting shaft rod; The two connecting shaft rods at the upper ends of the two scissor folding arms 3-4 are fixedly connected to the support top plate 3-5. A height adjustment lead screw 3-3 is arranged through the two connecting shaft rods at the lower ends. A slider is threadedly connected to the height adjustment lead screw 3-3. Among the two connecting shaft rods at the lower ends, one connecting shaft rod is fixedly connected to the bottom plate 2-3, and the other connecting shaft rod is fixedly connected to the slider; When the height adjustment lead screw 3-3 is rotated, the slider moves along the height adjustment lead screw 3-3. When the slider moves closer to the other connecting shaft rod, the support top plate 3-5 rises. When the slider moves away from the other connecting shaft rod, the support top plate 3-5 descends.

[0036] In use, bolts are passed through the through holes on the flange and the flange connection holes 4-2 at a suitable position and the matching nuts are tightened to fix the flange and the flange connecting plate. Then, the cross beam 5 is placed on the supporting top plate 3-5 of the supporting assembly 3. By rotating the height adjustment screw rod 3-3, the slider is driven to move along the height adjustment screw rod 3-3, the connecting shaft rod connected to the slider is driven to move, the hinged angle of the supporting rod is driven to change, and further the height of the supporting top plate 3-5 is driven to change. The cross beam 5 is placed on the supporting top plate 3-5, and thus the cross beam 5 and the flange are driven to be at the same horizontal height. Then, the center adjustment screw rod 3-2 is rotated to adjust the horizontal position of the central axis of the cross beam 5 so that the central axis of the cross beam 5 is collinear with the central axis of the flange. Then, the two positioning side plates 2 are slid so that the flange is in contact with the cross beam 5. After the two positioning side plates 2 are tightly abutted against the cross beam 5, the locking bolts are tightened to fix the two positioning side plates 2.

[0037] Furthermore, the cross beam 5 with a rectangular side cross-section can be stably placed on the supporting top plate 3-5, but the cross beam 5 with a circular side cross-section cannot be placed. Therefore, in this embodiment, a V-shaped positioning seat 6 is also provided. In use, the V-shaped positioning seat 6 is placed on the supporting top plate 3-5. A V-shaped groove for stably placing the cylindrical cross beam 5 is provided at the top of the V-shaped positioning seat 6. The end of the center adjustment screw rod 3-2 abuts against both sides of the V-shaped positioning seat 6. With the help of the V-shaped positioning seat 6, the stable placement, height adjustment and horizontal position adjustment of the cylindrical cross beam 5 can be realized.

[0038] This device is adapted to cross beams 5 and flanges of different models, different sizes and different shapes, can adjust the height and horizontal position of the cross beam 5, ensures the coaxial welding of the cross beam 5 and the flange, improves the welding quality and welding efficiency, has strong versatility, and is worthy of popularization and use in this field.
