The utility model discloses a novel welded structure strengthens the welding seam through rewelding tentaculiform beyond the welding bead strengthening otic placode intermediate cam portion, when welding seam release stress can from the cirrus at the beginning, the deformation that from this produces can not influence the main weld, and then the welding quality problem that results in such as welding stress can not use the weldment and exert an influence, welding quality has important meaning to the improvement.
Description
Technical field
The utility model is related to a kind of novel welding structure, belongs to tower crane connector field.
Background technology
Welding is used in combination by heating, pressurization or both, is that two workpiece produce the processing technology and connection combined between atom
Mode, is also to use most connected modes on tower crane product between parts.The joint portion that welded part is formed after weld formation
Position is weld seam, and the selection of welding procedure has highly important impact on the height of weldquality in welding process, therefore closes
Reason improves welding procedure, and the generation to reducing the weld defects such as weld crack, slag inclusion, pore plays a positive role, so as to carry
The quality of high weldment, and then improve the overall performance of tower crane.
In prior art designs, as shown in figure 1, when needing to carry out local strengthening to workpiece 1, typically using square otic placode
2 are welded on workpiece 1, while setting weld seam 3 around otic placode 2.Because weld seam is common angle welding or downhand weld
Deng being undertaken by commissure along the welding of welded part junction, the deformation in weldment shaping cooling procedure etc., easily because of welding
The presence of stress causes weldment deformation, the defects such as pore occurs.
The content of the invention
For the problem that above-mentioned prior art is present, the utility model provides a kind of novel welding structure, reduces welding
The stress concentration at position, it is to avoid produce weld crack, pore and welding deformation, greatly improve welding quality.
To achieve these goals, a kind of novel welding structure that the utility model is adopted, including workpiece one, for strengthening
The reinforcement otic placode of workpiece one, the reinforcement otic placode is welded on workpiece one；
It is described strengthen otic placode include being located at the triangular part of upper end, positioned at the square department of triangular part lower end, the triangular part and
Square department is integral type, and weld seam, the otic placode edge on the triangular part top are provided between the edge and workpiece one of the reinforcement otic placode
Place is provided with reinforcement of weld, and reinforcement of weld is connected with the weld seam.
Used as improvement, the weld seam is angle welding or downhand weld.
Used as improvement, the reinforcement of weld is tentaculiform, and the quantity of reinforcement of weld is two, the end of two reinforcements of weld
It is connected with weld seam.
Used as improvement, the reinforcement of weld is located at the outside of the welding bead between triangular part and workpiece one.
Used as improvement, the reinforcement of weld is angle welding or downhand weld.
Novel welding structure of the present utility model, by welding tentaculiform again beyond the welding bead for strengthening otic placode intermediate cam portion
Reinforcement of weld, can be from the beginning of at antenna when weld seam discharges stress, and resulting deformation does not interfere with main weld, and then welds
Caused by stress etc. problems of welded quality will not butt-welding fitting using impact is produced, have important meaning for welding quality is improved.

Specific embodiment
To make the purpose of this utility model, technical scheme and advantage of greater clarity, below by drawings and Examples,
The utility model is further elaborated.However, it should be understood that specific embodiment described herein is only to solve
The utility model is released, scope of the present utility model is not limited to.
Unless otherwise defined, all of technical term used herein and scientific terminology with belong to skill of the present utility model
The implication that the technical staff in art field is generally understood that is identical, herein in term used in the description of the present utility model only
It is to describe the purpose of specific embodiment, it is not intended that in restriction the utility model.
As shown in Fig. 2 a kind of novel welding structure, including workpiece 1, the reinforcement otic placode 4 for strengthening workpiece 1, institute
State reinforcement otic placode 4 to be welded on workpiece 1；
It is described strengthen otic placode 4 include being located at the triangular part 41 of upper end, positioned at the square department 42 of the lower end of triangular part 41, described three
Corner 41 and square department 42 are integral type, and between the edge and workpiece 1 of the reinforcement otic placode 4 weld seam 3, the triangular part 41 are provided with
The otic placode edge on top is provided with reinforcement of weld 5, and reinforcement of weld 5 is connected with the weld seam 3.
Used as the improvement of embodiment, the weld seam 3 is angle welding or downhand weld, is processed easy to use.
Used as the improvement of embodiment, the reinforcement of weld 5 is tentaculiform, and the quantity of reinforcement of weld 5 is two, and two strengthen
The end of weld seam 5 is connected with weld seam 3.
Used as the improvement of embodiment, the reinforcement of weld 5 is located at the outside of the welding bead between triangular part 41 and workpiece 1.
Used as the improvement of embodiment, the reinforcement of weld 5 is angle welding or downhand weld.
The utility model is by the reinforcement otic placode that makes into be made up of triangular part 41 and square department 42 by traditional square otic placode 2
4, i.e. otic placode upper end are set to the shape of similar triangle, meanwhile, during welding, between triangular part 41 and workpiece 1
Welding bead beyond weld tentaculiform reinforcement of weld 5 again, so weld seam discharge stress when can be resulting from the beginning of at antenna
Deformation does not interfere with main weld (strengthening the weld seam 3 of otic placode 4 and the junction of workpiece 1), and then weldering caused by welding stress etc.
Connect quality problems will not butt-welding fitting using produce impact, for improve welding quality have important meaning.
The novel welding structure not only reduces welding deformation by the appropriate shape and welding procedure for changing weldment, carries
High welding quality, while improve the tower crane product identification rate, is suitable to promote on a large scale.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modification, equivalent or improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
