Detailed description of the invention
All features disclosed in this description, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this description (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in detail.
As shown in Figure 1 and Figure 2, according to one embodiment of present invention, the present embodiment discloses a kind of engineering cargo floor general assembly and welding method, the present embodiment is by changing the conventional assemble sequence of cargo floor assembly, reach space for the creativity, improve welding operation environment, and then improve the object of welding quality.Concrete, as shown in Figure 1, the present embodiment engineering cargo floor general assembly and welding method are under assembled tool specification, and lorry engineering cargo floor assembly drops into assembling, the first step successively by the order of 1 ~ 5, combination frame 1; Second step, lays longeron 2; 3rd step, arranges reinforcement 3; 4th step, places base plate 4; 5th step, installation accessories 5.
Wherein, preferably, reserve base plate when laying longeron 2 and arrange reinforcement 3 according to base plate thickness in the present embodiment and place gap.
In the first step, second step, it is fixed that the 3rd step three step implements the solid welding of pad site respectively.Concrete, when self-indulgent beam and layout reinforcement, place gap according to the pre-Cincinnati of base plate thickness.The solid welding of pad site is implemented fixed during combination frame.The solid welding of pad site is implemented fixed when laying longeron; The solid welding of pad site is implemented fixed during described layout reinforcement.
Further preferred embodiment, as shown in Figure 2, in the present embodiment on jig, implement integral solder to the assembly after 1,2,3 step combinations by a → b → c position order, wherein, aa, bb, cc position is double welds simultaneously.
Concrete, after layout reinforcement, carry out integral solder according to following steps in the present embodiment:
A. implement longeron termination to weld with the pad position of bezel contact position;
B. implement reinforcement termination to weld with the pad position of longeron contact position;
C. implement reinforcement termination to weld with the pad position of bezel contact position.
Preferably, as a and a position welding in Fig. 2, be and implement each longeron two terminations simultaneously and weld with the pad position of bezel contact position.When there being two longerons, two longeron terminations that the two ends of two longerons have altogether are welded with corresponding bezel contact position simultaneously.
As b and b position welding in Fig. 2, be enforcement reinforcement termination simultaneously and weld with the pad position of two face contact positions of a longeron with each longeron contact position and reinforcement termination.As having two longerons, the contact site, reinforcement termination that the reinforcement termination contact site corresponding with it, the two sides of one of them longeron is corresponding with it with the two sides of another longeron welds simultaneously.
As c and c position welding in Fig. 2, be enforcement reinforcement termination simultaneously and weld with the pad position of two limit contact positions of frame.As seen from Figure 2, wherein these two limits of frame are two symmetrical limits, and it is parallel with longeron.
After the assembly be assembled into frame, longeron and reinforcement face has been welded, upset assembly, has welded another side by abovementioned steps, mode, has realized the two-sided welding of reinforcement termination and frame and longeron.
As preferred embodiment, the present embodiment, when placing base plate, can adopt and sectionally assembledly fill in base plate, full slice system also can be adopted to fill in base, fill in base plate and adjust equal postpone, weld in the usual way.Weld as installation accessories such as mud guard bearing, profile lamp socket, rope hooks on request again.Thus can improve cargo floor assembly manufacture craft reliability, improve lifting load-bearing ability, ensure that the structural strength of engineering cargo floor from technique.
