Detailed Description
In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below with reference to the accompanying drawings and examples.
Referring to fig. 1 to 11, a welding platform for an upper beam of a car bottom box is shown, the upper beam of the car bottom box comprises long beams 10 arranged in parallel at intervals and longitudinal beams 20 connecting the long beams 10 symmetrically, the long beams 10 and the longitudinal beams 20 are of channel steel structures, as shown in fig. 1 to 3, and a rectangular frame structure is shown on a car bottom box Liang Rutu after the long beams 10 and the longitudinal beams 20 are connected.
Aiming at the problems of errors and overturning difficulty existing in the current welding of the upper beam of the car bottom box, the utility model provides a welding platform, which comprises a long beam fixing device for fixing and positioning each long beam 10, the concrete structure is shown in fig. 4-5, the long beam fixing device comprises horizontal sliding rails 1 arranged at horizontal intervals, and longitudinal sliding rails 2 arranged on each horizontal sliding rail 1 at intervals in a sliding manner, and each longitudinal sliding rail 2 is provided with a clamping block 3 for embedding the end part of the long beam 10.
Preferably, the end parts of the symmetrical transverse sliding rail 1 are provided with connecting rods 7 which connect the transverse sliding rail 1 to form a rectangular frame structure, and driving cylinders 8 which drive the longitudinal sliding rail 2 to move along the length direction of the transverse sliding rail are arranged on the connecting rods 7, when in operation, the two ends of a single long beam 10 are placed between clamping blocks 3 on the longitudinal sliding rails 2 on two sides, then the longitudinal sliding rail 2 on two sides is driven by the driving cylinders 8 to slide on the transverse sliding rail 1 in opposite directions, after the clamping blocks 3 are contacted with the end parts of the long beam 10, the two long beams 10 are clamped and fastened, and when the longitudinal beams 20 are connected after clamping, the distance between the symmetrical long beams 10 can be adjusted by sliding the longitudinal sliding rails 2 so as to facilitate the connection of the longitudinal beams 20. The transverse sliding rail 1 and the longitudinal sliding rail 2 have higher verticality (such as that of being applied to a numerical control machine tool), so that the clamping blocks 3 arranged on the longitudinal sliding rail 2 at intervals also ensure higher flatness, the long cross beams 10 clamped at intervals can keep end surface flushness, and the problem that the symmetrical end surfaces of the long cross beams 10 have displacement deviation due to initial connection of connecting screws and rotation at present is solved.
Because the long beam 10 is in a channel steel structure and is composed of a side wall surface a and an upper top surface b and a lower top surface b, in order to ensure that the height of the long beam 10 clamped by the distance is consistent, as shown in fig. 6, a groove 3a for embedding the end part of the long beam 10 is vertically and penetratingly formed in the clamping block 3, the side wall surface a of the long beam 10 can be embedded, and the upper top surface b and the lower top surface b correspond to the upper top surface and the lower top surface of the clamping block 3, as shown in fig. 7, a height adjusting screw 4 in contact with the inner top surface of the long beam 10 is further arranged at the top of the clamping block 3, and after the side wall surface a of the long beam 10 is embedded in the groove 3a, the upper top surface b of the long beam 10 corresponds to and contacts with the height adjusting screw 4, and the up-down lifting adjustment of the long beam 10 can be realized by rotating the height adjusting screw 4, so that the distance of the long beam 10 is high, and errors of welding finished products are reduced.
On the basis of adjusting the height of the long beam 10, since the long beam 10 and the groove 3a of the clamping block 3 have embedded gaps, and since the long beam 10 is of an open channel steel structure, after being hung on the height adjusting screw 4, the side wall surface a of the long beam has vertical deflection, and thus has a vertical error, in order to solve the problem, as shown in fig. 8-9, an adjusting convex rib 31 which is contacted with the inner side wall of the long beam 10 is arranged in the middle of the side wall of the groove 3a, and horizontal adjusting screws 5 which can be tightly propped against the outer wall surface of the long beam 10 are arranged on the side walls of the clamping block 3 on the upper side and the lower side of the adjusting convex rib 31 in a penetrating way. As shown in fig. 9, the regulation function is as follows: after the inner wall of the side wall surface a of the long beam 10 contacts with the adjusting rib 31, the horizontal adjusting screw 5 at the upper side and the lower side is rotated, so that the whole long beam 10 vertically rotates (shown by arrow c) under the support of the adjusting rib 31 (preferably in a circular arc structure), the verticality of the side wall surface a can be detected preferably through a detecting ruler, the long beam 10 can be in a vertical state, and the welding forming precision of the long beam is improved.
In order to facilitate the assembly of the long beam 10, as shown in fig. 4-5 and 10-11, a supporting slide bar 6 for supporting the long beam 10 is also arranged in the middle of the transverse slide rail 1 in a sliding manner at intervals. When in welding, firstly, the long cross beam 10 is placed on the support slide bar 6, the clamping block 3 is driven by the driving cylinder 8 to be close to the end part of the long cross beam 10 and embedded, and then the long cross beam 10 can be separated from contact with the support slide bar 6 under the action of adjusting the height of the long cross beam 10 by rotating the height adjusting screw 4.
In order to facilitate welding of the inner side of the long cross beam 10, the welding platform further comprises a rotation mechanism for turning over the long beam fixing means. The connecting rod 7 outside of the transverse slide rail 1 is preferably provided with a rotary disk 91 and a rotary seat 92, and the long beam fixing device, the long cross beam 10 and the longitudinal beam 20 can be turned over by the rotation of the rotary disk, so that the inside can be welded quickly. The welding mode can adopt robot welding, and can effectively cooperate with the welding platform to improve the welding efficiency and the welding quality.
The principle of the utility model is as follows: during welding, firstly, the long cross beam 10 is placed on the support slide bar 6, the clamping block 3 is driven by the driving cylinder 8 to be close to the end part of the long cross beam 10 and embedded, and then the long cross beam 10 can be separated from contact with the support slide bar 6 under the action of adjusting the height of the long cross beam 10 by rotating the height adjusting screw 4; the long cross beam 10 is driven to vertically rotate integrally under the support of the adjusting convex edges 31 through the horizontal adjusting screw rods 5 on the upper side and the lower side, the verticality of the long cross beam is adjusted, a longitudinal beam is connected to the adjusted long cross beam, the long cross beam and the outer side of the longitudinal beam are welded after the connection, the whole body is turned over through the rotating disc 91 after the welding is finished, and the joint of the inner sides of the long cross beam and the longitudinal beam is welded.
