Description

Fastening oblique iron welding tool

Technical Field

The utility model relates to the technical field of fastening wedge welding positioning tools, in particular to a fastening wedge welding tool.

Background

The existing tower crane is attached with two types, the first type is formed by connecting four groups of L-shaped ring beams end to end, the ring beams are fixed through bolts, the second type is formed by connecting two groups of U-shaped ring beams, and the ring beams are hinged through pin shafts. When the first tower crane is attached and fixed with the standard joint, the coordination of the attachment and the standard joint can be controlled by adjusting the bolt. When the second middle tower crane is attached to the standard section, because the second middle tower crane cannot be adjusted, a fastening wedge is usually used for inserting the parts of the tower crane attachment and the standard section, so that the cooperation between the tower crane attachment and the standard section is ensured.

The fastening wedge comprises a wedge 9 and a clamping plate 10, wherein the clamping plate 10 is fixedly connected to two parallel side walls of the wedge 9 respectively, a positioning tool is needed when the clamping plate 10 and the wedge 9 are welded, the positioning tool is shown in fig. 2, a first positioning groove 11 for placing the wedge 9 and a second positioning groove 12 for placing the clamping plate 10 are formed in the positioning tool, the wedge 9 and the clamping plate 10 are placed into the first positioning groove 11 and the second positioning groove 12 respectively before welding, the clamping plate 10 and the wedge 9 are shielded due to the fact that the existing positioning tool is used for fixing the welding positions of the wedge 9 and the clamping plate 10, and when the wedge 9 and the clamping plate 10 are welded, the clamping plate 10 and the wedge 9 are needed to be pinched by hands to be taken out from the positioning tool and then welded. In the actual working process, the clamping plate 10 and the wedge block 9 are taken out in the process, due to the operation reasons, the clamping plate 10 and the wedge block 9 are frequently dislocated, if the dislocation can be found in time, the clamping plate 9 and the clamping plate 10 can be positioned again, if the dislocation cannot be found, the welding is finished, and the rejection rate of the product is high. Aiming at the problems in the prior art, we provide a fastening oblique iron welding tool.

Disclosure of Invention

Aiming at the problems in the prior art, the utility model provides a fastening oblique iron welding tool which is realized by the following technical scheme:

the utility model provides a fastening oblique iron welding frock, includes the locating bench, locating bench one end fixedly connected with baffle, locating bench intermediate position integrated into one piece has the location arch of slope, the one end that the location arch is close to the baffle is the slope lower extreme, the constant head tank has been seted up to the locating bench, the constant head tank is located the bellied both sides of location, the location arch is higher than the constant head tank.

The utility model is further provided with: the lower terminal surface fixedly connected with pivot of locating bench, fixedly connected with bearing in the pivot, fixedly connected with supporting seat on the bearing outer race.

The utility model is further provided with: the lower end face of the supporting seat is fixedly connected with a magnet sheet.

In summary, the beneficial technical effects of the utility model are as follows:

the tool uses the inclined plane of the wedge block as a reference for positioning, can position the wedge block and the clamping plate, exposes the welding positions of the wedge block and the clamping plate, and does not need to be taken down from the positioning table when the clamping plate and the wedge block are welded, so that the welding is directly completed on the tool, the relative positions of the clamping plate and the wedge block are prevented from moving, and the yield of products is ensured.
