Abstract
The invention discloses a miniature excavator rotation frame which comprises a left frame, a top frame, a right frame and beams. The miniature excavator rotation frame is characterized in that an original frame is changed to be in a joint type from an overall type and divided into the left frame, the top frame and the right frame in a three-joint mode, wherein the left frame, the top frame and the right frame are connected together in a buckling, or embedding or welding mode, an original middle beam is changed to be in a three-joint mode, and the three beams are connected together in a buckling, or embedding or welding mode. The line production is easy to achieve, the takt is intense, the errors are small, part deformation is small, and the strength is high.
Description
Technical field
the present invention relates to a kind of mini-excavator reversing frame, be applicable to 6 tons of following middle-size and small-size excavators.
Background technology
in the situation that revolving platform of excavator functional structure is constant, in order to meet the quality of production, cost of production, the production efficiency requirement of platform, need to carry out welded construction process optimization to platform, the quality of production, cost of production, production efficiency are maximized.Platform structure all uses slab, middle plate in a large number, and the complex structure productive temp of part own is difficult to reasonable arrangement.Platform is large and peripheral component material thickness is little as area, and core component material thickness is large, and welding is distortion easily, and the difficulty of welding post-equalization is large.Design the part relative separation of a kind of dual-side parts and material thickness, centre, two side portions material thickness of slab are changed relatively all little, can be greatly improved to welding handicraft product quality.How to design and a kind ofly meet good process and superior in quality platform is the knotty problem that we encounter.
Summary of the invention
the present invention is just to provide a kind of mini-excavator reversing frame, can make the relative variation of thickness of slab of the each assembly of platform little, and welding deformation is easily controlled, productive temp reasonable arrangement.Can allow welding deformation, welding error revise in being welded into new construction platform follow-up simultaneously, thereby draw the new construction platform of more optimizing.
technical solution of the present invention is such: a kind of mini-excavator reversing frame, comprise prior art structure, left frame, top frame, correct frame, crossbeam, it is characterized in that the top between left frame (2) and left frame (2) is top frame (3), centre is crossbeam (5), upwards boss of top frame (3), crossbeam (5) is divided into left, center, right three-section type and connects, left frame (2), top frame (3), correct frame (4) connects uses embedded connection, also available being welded to connect, crossbeam (5) between left frame (2) and correct frame (4) is connected with embedded.
Left frame (2), correct frame (4), top frame have dividing plate between (3).
The crossbeam (5) of left, center, right is connected with buckling into formula and/or embedded and/or welded type.
Left frame (2), correct frame (4), top frame (3), for crossbeam (5), angle steel, horizontal steel, sheet Steel material are made.
Outstanding advantages of the present invention is: Integral cross beam is divided into three joints and engages and form, framework be also by left, center, right block diagram frame by synthetic, make to produce easy for installation, calibration correction is easy, the error of appearance is little, is suitable for realizing streamline industry.
Brief description of the drawings
fig. 1 is prior art structural representation.
fig. 2 is the structural representation of a kind of mini-excavator reversing frame of the present invention.
reference numeral: prior art structure (1), left frame (2), top frame (3), correct frame (4), crossbeam (5).
Detailed description of the invention
below in conjunction with accompanying drawing, the invention will be further described.
embodiment 1, with reference to Fig. 1～Fig. 2, chassis body structure formation is engaged and is formed by left frame (2), correct frame (4), top frame (3), and middle crossbeam is made up of left, center, right three joints.Left frame (2), correct frame (4), top frame (3) respectively have a style of one's own, and make with angle steel, horizontal steel, sheet Steel material.Between left frame (2), correct frame (4), top frame (3), connect with fastening type, with embedded, all achieve the goal equally with welded type.Be exactly to allow error and the distortion of parts welding be proofreaied and correct elimination in process fixing and location.The weld seam of the process that three large parts are welded to each other is few, and strength of parts is good.This structure welding reduces final welding link weld seam, and the process of three large component combinations is the processes of reorientating and proofreading and correct.Can revise well distortion and the foozle of part.Fixed with main platform body and be welded into whole platform by tool locating by left part platform, right part platform, the beam design of this platform becomes three joints.Can realize beat, streamline is produced; Can allow welding deformation, welding error revise in being welded into new construction platform follow-up simultaneously, thereby draw the new construction platform of more optimizing.
Embodiment 2, a kind of mini-excavator reversing frame, comprise prior art structure, left frame, top frame, correct frame, crossbeam, it is characterized in that the top between left frame (2) and left frame (2) is top frame (3), centre is crossbeam (5), upwards boss of top frame (3), crossbeam (5) is divided into left, center, right three-section type and connects, left frame (2), top frame (3), correct frame (4) connect uses embedded connection, also available being welded to connect, the crossbeam (5) between left frame (2) and correct frame (4) is connected with embedded.Left frame (2), correct frame (4), top frame have dividing plate between (3).The crossbeam (5) of left, center, right is connected with buckling into formula and/or embedded and/or welded type.Left frame (2), correct frame (4), top frame (3), for crossbeam (5), angle steel, horizontal steel, sheet Steel material are made.
Claims (4)
1. a mini-excavator reversing frame, comprise left frame, top frame, correct frame, crossbeam, it is characterized in that the top between left frame (2) and left frame (2) is top frame (3), centre is crossbeam (5), upwards boss of top frame (3), crossbeam (5) is divided into left, center, right three joints and connects, left frame (2), top frame (3), correct frame (4) connect uses embedded connection, also available being welded to connect, the crossbeam (5) between left frame (2) and correct frame (4) is connected with embedded.
