Problems solved by technology
Since the relevant clamping parts on the tailstock must have problems such as wear, sagging, and deformation during use, they will directly interfere with the verticality
However, existing manufacturers can only achieve regular calibration and maintenance, and cannot find the problem of verticality in time, resulting in untimely adjustment of equipment, damage to the quality of batch products, and even waste of rework

[0027] Example: a tower crane standard section welding positioning tool
[0028] according to Figure 1-8 As shown, the basic structure of the tooling includes two opposite support bases 2, on which a mounting seat 3 is fixed, and the upper part of the mounting seat 3 is provided with a bearing seat, and the mounting seat 3 can be moved through the bearing seat. The rotating shaft 4 is installed with the rotating shaft 4, and the inner end of the rotating shaft 4 is provided with a tailstock frame 5 which is fixedly connected to it. The tailstock frame 5 is a rectangular frame structure with rice-shaped reinforcing ribs. Outside the tailstock frame 5 , the rotation of the rotating shaft 4 can drive the tailstock frame 5 to rotate. A transmission mechanism and a power mechanism for driving the rotating shaft 4 to rotate are installed in the mounting seat 3 .
[0029] Specifically, the transmission mechanism includes an upper sprocket fixed on the rotating shaft 4, a lower spr...

The invention discloses a standard section welding positioning tool for a tower crane, which mainly relates to the field of welding tooling. It includes two synchronously rotating tailstocks, and the four corners of the tailstock are fixedly installed with a clamping mechanism. The side is provided with a first emitter and a second emitter, the first emitter is installed with a first light source emitting point laser light, the second emitter is installed with a second light source emitting point laser light, and the plane of the beam path of the first light source is located It is perpendicular to the plane where the beam path of the second light source is located. When the vertical tailstock of the main chord is clamped and fixed between the top pieces, the light beam emitted by the first light source has a light spot in the center of the end face of the main chord. The light beam emitted by the second light source has a light spot at the center of the end face of the main chord. The beneficial effect of the invention is that it is easy to find out the verticality problem when the main chord is installed and fixed before welding, and the welding precision is improved.
Description
technical field [0001] The invention relates to the field of welding tooling, in particular to a welding positioning tooling for a standard section of a tower crane. Background technique [0002] Tower cranes are widely used in construction, and the crane manufacturing industry has gradually formed a certain scale. Crane is a special operation equipment, its product quality cannot be ignored, especially the welding quality of the standard section directly affects the quality of the whole machine. In the mass production process, the welding quality must be guaranteed by welding tooling, such as verticality, parallelism, interchangeability. [0003] The size of the standard section is fixed and uniform, and its structure is generally composed of a coupling sleeve, a main chord, a horizontal web of an inclined web, and a gusset plate. The main chord is the main support part of the main frame, and the primary concern in welding is its verticality. In the existing fixed toolin...
