Abstract
The invention discloses a technological method for machining a large excavator door. The method is characterized in that an air inlet grid is wholly welded, and a front vertical rib, a middle vertical rib, an upper transverse rib, a first inclined rib, an inclined rib, a right vertical rib, a lower transverse rib, a small vertical rib and an air inlet grating are welded together to form an air inlet grid; a front reinforcing rib, a rear reinforcing rib, a door hinge, reinforcing ribs and a door plate are welded; a left vertical rib and a right vertical rib are welded with a left reinforcing rib and a right reinforcing rib, and two components are installed and welded; and finally, high-strength structural glue is used for gluing the middle vertical rib, the upper transverse rib, the lower transverse rib, the small vertical rib and the door plate. The welding and high-strength structural glue pasting technological method is adopted, excavator door welding deformation is effectively reduced while rigidity of the door plate is reinforced, grinding and ash scraping in the later period are not needed, spraying can be achieved after electrophoresis, and the appearance quality and batch production efficiency of the excavator door can be greatly improved.
Description
Technical field
The present invention relates to a kind of process of machining large excavator car door, be specifically related to a kind of process of machining large excavator band air inlet grid car door.
Background technology
In excavator manufacture field, car door is the outward appearance vitals of pick machine, and the workmanship of car door entirety directly has influence on complete machine presentation quality.Car door is aided with welding reinforcement by the door-plate suppressed to form, on large excavator heat sink side car door, major part is all welded with air inlet grid, as Figure 1-3, comprise the door-plate 4 of band air inlet grid 14, left, center, right with air inlet grid 14 are respectively equipped with left stud 2, middle stud 3, right stud 10, the left side of left stud 2 is provided with left reinforcement 1, the right side of right stud 10 is provided with right reinforcement 5, air inlet grid 14 is provided with little stud 13 near the edge at door handle 15 place, upside is provided with horizontal bar 6, and downside is provided with lower horizontal bar 12; The downside of door-plate 4 is provided with reinforcement 11, and the side of door-plate 4 is provided with hinge 9; The both sides of air inlet grid 14 are also provided with two diagonal bars, i.e. diagonal bar 1 and diagonal bar 28.
Traditional preparation method is that air inlet grid 14 is direct and door-plate 4 welds together, because the sheet material of door-plate 4 is thinner, easily cause door-plate 4 to be out of shape when air inlet grid 14 welds, outer surface has crator to need manual polishing, later stage surface treatment need be scraped ash and be struck off, and artificial intensity is large.For reducing welding deformation, enhancing productivity, without the need to manual polishing, scraping ash and can spray, ensureing, under the performance requirement that air inlet grid 14 and door-plate 4 are firmly connected, must ensure that air inlet grid 14 does not directly weld with door-plate 4.
Summary of the invention
Problem to be solved by this invention is to provide a kind of car door process can solve the distortion and outside crator that cause when air inlet grid welds with door-plate, improves batch production efficiency, reduces artificial surface process man-hour.
In order to solve the problem, technical scheme of the present invention there is provided a kind of process of machining large excavator car door, it is characterized in that, first air inlet grid entirety is welded, weld together by front stud, middle stud, upper horizontal bar, diagonal bar one, diagonal bar, right stud, lower horizontal bar, little stud and air-inlet grille and form air inlet grid; Then front reinforcement, rear reinforcement, hinge, reinforcement and door-plate are welded; Then left stud, right stud are welded with left reinforcement, right reinforcement respectively, make two assembly assembly weldings; Finally use high strength structural adhesion by middle stud, upper horizontal bar, lower horizontal bar, little stud and door-plate.
Preferably, described left stud all adopts intermittent weld mode to weld with the welding manner between left reinforcement, between right stud with right reinforcement.
Preferably, described high strength structural adhesion is ergo1920.
The present invention adopts welding to add the gluing process connect of high-strength structure, while reinforcement door-plate rigidity, effectively reduces automobile door welding distortion, later stage is also without the need to polishing, scrape ash, just can spray paint after electrophoresis, greatly improve the presentation quality of car door and the efficiency of batch production.
Accompanying drawing explanation
Fig. 1 is the front view of band air inlet grid car door;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
Detailed description of the invention
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
A kind of process of machining large excavator car door:
Step 1): front stud 2, middle stud 3, upper horizontal bar 6, diagonal bar 1, diagonal bar 8, right stud 10, lower horizontal bar 12, little stud 13 are welded together composition air inlet grid 14;
Step 2): front reinforcement 1, rear reinforcement 5, hinge 9, reinforcement 11 are welded with door-plate 4;
Step 3): adopt intermittent weld mode to weld with left reinforcement 1, right reinforcement 5 respectively left stud 2, right stud 10, make step 1) assembly that obtains and step 2) the assembly assembly welding that obtains;
Step 4): finally use high strength structural adhesion ergo1920 by middle stud 3, upper horizontal bar 6, lower horizontal bar 12, little stud 13 and door-plate 4, between processing period, large of the middle thin plate of guarantee door-plate 4 must not have solder joint.
