Abstract
The utility model relates to a clamp structure for a fuel injection opening of an aluminum alloy fuel tank of a heavy-duty truck, which comprises the following components: a base plate, a column, a cantilever beam and a clamp sleeve. An upper surface of the base plate is provided with the clamp sleeve. The column is vertically equipped above an end part of the base plate. The column is horizontally connected with a fixed cross beam. A motion positioning block is equipped above a fixed cross beam. The cantilever beam is equipped at the upper end of the column. The clamp structure for the fuel injection opening of the aluminum alloy fuel tank of the heavy-duty truck is advantageous in that: a cantilever beam structure is adopted for the welding clamp; through positioning an inner hole of a fuel injection opening base of the fuel tank, the fuel tank body and the fuel injection opening base are positioned and clamped; maintaining of the whole body to be an elastic member after straight welding seam welding and shaping is facilitated; external form positioning and clamping the two end faces can be adopted; a torsional force is transmitted through the fuel tank body under the precondition that deformation of the fuel tank is not caused; welding to the end cap girth joint can be finished in one time; heat radiation is facilitated and welding-to-through at the end cap side is prevented; and furthermore the clamp structure according to the utility model has the following advantages: stabilizing welding quality, saving production cost and obtaining high welding efficiency.
Description
Technical field
The utility model relates to aluminium alloy fuel tank solder technology, relates in particular to a kind of truck aluminium alloy fuel tank pouring orifice clamp structure.
Background technology
Make fuel tank of vehicle for aluminium alloy that present truck adopts; Have regeneration rate advantages of higher good in economic efficiency in corrosion-resistant, in light weight, product life cycle, material, meet at present automobile production in the world to green manufacturing, reduce limited resources consumption, energy-saving and environmental protection direction Development Trend.Solder technology is the difficult point and the core technology of aluminium alloy fuel tank exploitation, and the welding of thin plate aluminium alloy enclosed construction is difficulty more, and therefore in industrialization process, will solve following several respects problem: 1. the aluminium alloy fuel tank of weld jig is located the clamping problem; 2. aluminium alloy fuel tank pouring orifice plate sheet welding technological problems; 3. long weld seam welding procedure of aluminium alloy fuel tank thin plate enclosed construction and welding deformation problem; 4. the weld joint automatized Welding Problems in drum type cross section; 5. material cost accounts for 80% of aluminium alloy fuel tank cost, and the defective material that will cause of welding quality is scrapped, and therefore welds the percent defective height and will make product not have competitiveness.In addition, the weld seam of pouring orifice seat and fuel tank body is the space curve structure, and the thin aluminium alloy plate of wall thickness, is very easy to burn-through; Because robot pose changes complicacy during the welding space curve, it is correct to be not easy to adjust to attitude like the too fast robot of speed of welding welding gun, and appearance of weld is bad, also is easy to generate pore, can not satisfy the seal request of fuel tank.Therefore, comprehensive above aspect need reasonably be improved the weld seam device of existing pouring orifice seat and fuel tank body.
The utility model content
To above defective; The utility model provides a kind of and helps the fuel tank body and truck aluminium alloy fuel tank pouring orifice clamp structure that the pouring orifice seat positions and clamps, can stablize welding quality, save production cost, to solve many deficiencies of prior art.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of truck aluminium alloy fuel tank pouring orifice clamp structure; Comprise base plate, column, cantilever beam and anchor clamps body; Plate upper surface is installed an anchor clamps body; Said bottom end top vertically is provided with a column, and said column level connects fixed cross beam, this fixed cross beam upside installation and moving locating piece; Be positioned at the column upper end cantilever beam is installed.
The beneficial effect of the described truck aluminium alloy of the utility model fuel tank pouring orifice clamp structure is: this weld jig adopts cantilever fine strain of millet structure; Pouring orifice seat endoporus location through fuel tank; Fuel tank body and pouring orifice seat are positioned and clamp, help making whole through still keeping an elastomer after welding straight weld and the shaping; Can adopt the external form location; Both ends of the surface clamp; Under the prerequisite that does not cause the fuel tank distortion, transmit twisting resistance,, also help heat radiation so that the end cap girth joint can once weld completion through the fuel tank body; Prevent to wear, can stablize welding quality, save production cost, welding efficiency is very high at the end cap face down bonding.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the said truck aluminium alloy of the utility model embodiment fuel tank pouring orifice clamp structure figure;
Fig. 2 is the fuel tank view of the said fixture application welding of the utility model embodiment.
Among the figure:
1, base plate; 2, column; 3, cantilever beam; 4, fixed cross beam; 5, running fix piece; 6, anchor clamps body; 7, aluminium alloy fuel oil casing; 8, pouring orifice.
The specific embodiment
Shown in Fig. 1-2; The described truck aluminium alloy of the utility model embodiment fuel tank pouring orifice clamp structure; Comprise base plate 1, column 2, cantilever beam 3 and anchor clamps body 6; Said base plate 1 upper surface is installed an anchor clamps body 6 and is positioned at this top, base plate 1 end one column 2 vertically is set, and said column 2 levels connect fixed cross beam 4, these fixed cross beam 4 upside installation and moving locating pieces 5; Be positioned at column 2 upper ends cantilever beam 3 is installed.In use, this weld jig is through adopting cantilever fine strain of millet 3 structures, and the seat endoporus location of the pouring orifice 8 through aluminium alloy fuel oil casing 7 positions and clamps fuel tank body and pouring orifice seat.
Above embodiment is the more preferably specific embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection domain of the utility model.
