Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of preferred embodiment of the present invention is described in detail.
The invention provides a kind of welding method of fork truck unit frame, this fork truck unit frame as shown in Figure 1, unit frame is by left vehicle frame 1, right vehicle frame 2, rear tailstock 3, front transverse slat 4 with, rear transverse slat 5, connecting plate 14 and stiffener 25 are welded into entirety on same clamping mould, wherein left vehicle frame 1 and right vehicle frame 2 are symmetrical set, welding method is identical, left, right vehicle frame is by a left side, right case and backplate 6, upper plate 7, gusset 8 and pedal 9 are welded, wherein left, right case is by monoblock type inside panel 10, front panel 11, exterior panel 12 and tank cover 13 are welded, vehicle frame adopts all-in-one-piece inside panel, make welding procedure simple, convenient, just formed product can be realized without the need to secondary clamping, production efficiency is high, the length of monoblock type inside panel changes according to vehicle, length range is 1500-4000mm, the particular location A of monoblock type inside panel front axle centre has been shown in Fig. 1.In order to increase the intensity of unit frame, swash plate 24 can be welded with between monoblock type inside panel 10 afterbody of left and right vehicle frame and rear tailstock 3.
Unit frame being provided with multiple vehicle frame functional part, comprising the gearbox leg 15 for connecting gearbox base angle; Be used for the air filter bracket 16 of air filter is installed; For the engine supporting leg 17 at connecting engine base angle; Connect lower header support 18 and the upper water box support 19 of water tank leg; Connect the air spring support 20 of air spring; The battery cell bracket 21 of storage battery is installed; Connect the dump ram bearing 22 of dump ram; Limiting plate 23; And counterweight support plate 26.Wherein gear-box bracket 15 and engine supporting leg 17 are arranged on monoblock type inside panel 10, air filter bracket 16 and battery cell bracket 21 are arranged on tank cover 13, lower header support 18 and upper water box support 19 are arranged on the inner side of monoblock type inside panel 10 afterbody, dump ram bearing 22 is arranged on upper plate 7 front end, and limiting plate 23 is welded on the outside of monoblock type inside panel 10 afterbody.
Composition graphs 2 and Fig. 3 again, specifically describes as follows to the welding method of fork truck unit frame:
With the front axle centre of monoblock type inside panel 10 for benchmark, front panel, exterior panel, tank cover are placed on workbench, first locate tank cover with the front axle centre of monoblock type inside panel, then locate exterior panel and front panel with tank cover, such welding forms a left box body.With this casing location on the table, benchmark, still with the front axle centre of monoblock type inside panel, comes positioning welding backplate, upper plate, gusset, pedal, and such welding forms a left vehicle frame.
Right vehicle frame and left vehicle frame are symmetrical set, weld left vehicle frame on one side, the right vehicle frame of another side is welded again with same process, after both sides type frame has welded, they are placed on a workbench, and utilize Frame Welding mould to locate, positioning datum still selects the front axle centre of monoblock type inside panel, weld rear tailstock, front transverse slat, rear transverse slat, connecting plate, swash plate and stiffener successively, form unit frame.
Then by vehicle frame functional part equally with monoblock type inside panel for benchmark, correspondence is welded on relevant position, and welding completes.
The above embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determine.
