Abstract
The invention discloses a structure for connecting a door panel of a side door of an excavator with reinforcing ribs. The structure comprises the vertical reinforcing rib and the transverse reinforcing ribs. The vertical reinforcing rib is vertically arranged at the right side of the side door panel and attached to the inner side of the side door panel. The four edges of the side door panel are all overturned inwards. The two ends of the vertical reinforcing rib abut against and are welded to the overturned edges at the upper end and the lower end of the side door panel. The right ends of the transverse reinforcing ribs abut against the vertical reinforcing rib and are compacted through a right pressing plate and welded to the overturned edge and the pressing plate at the left side of the side door panel. The attachment position of each transverse reinforcing rib and the door panel is bonded through structural adhesive. The right pressing plate is welded to the vertical reinforcing rib, and the left pressing plate is welded to the overturned edge at the left side of the side door panel.

The above-mentioned technical problem of the present invention is mainly addressed by following technical proposals:
A kind of excavator side door door-plate and the attachment structure of reinforcement, including vertical strengthening ribs and cross reinforcing；Vertical reinforcement
What muscle was vertical be arranged on the right side of side door plate and fits with the inner side of side door plate, and the surrounding of side door plate, all to in-flanges, is vertically strengthened
The flange at two ends upper and lower with side door plate, the two ends of muscle holds out against and welds；The right-hand member of cross reinforcing withstands on vertical strengthening ribs and leads to
Crossing the compacting of right pressing plate and weld with vertical strengthening ribs and right pressing plate, left end withstands on and passes through left pressing plate at the flange on the left of side door plate
Compacting is also welded with on the left of side door plate and with the flange on the left of side door plate and pressing plate, and right pressing plate welds with vertical strengthening ribs, left pressure
Flanging welded on the left of plate and side door plate.
Further, the medial surface of described cross reinforcing and vertical strengthening ribs and side door plate is all by structure glue glue
Connect.
Further, described structure glue is adopted as the TS830 type structure glue of Tianshan Mountains, Beijing new material technology company limited.
Further, the quantity of described cross reinforcing is 2, and the two be arranged in parallel.
Further, vertical strengthening ribs is provided with die mould protruding, is welded with hinge at die mould high spot.
Further, it is provided with die mould depression in the left side of side door plate, is welded with door lock at die mould recess.
Further, flanging welded on the left of backset, backset and side door plate it is provided with in side door plate lower left, in side door plate bottom right
Angle is provided with the flanging welded below bent plate, bent plate and side door plate.
The invention has the beneficial effects as follows: side door plate exterior finish is without any solder joint, it is to avoid the side door that thermal weld stress causes
Plate deforms, and effectively improves the presentation quality of side door.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to
Other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
As it is shown in figure 1, a kind of excavator side door door-plate and the attachment structure of reinforcement, including vertical strengthening ribs 9 with horizontal
Reinforcement 2；What vertical strengthening ribs 9 was vertical be arranged on the right side of side door plate 1 and fits with the inner side of side door plate 1, the surrounding of side door plate 1
All to in-flanges, the two ends of vertical strengthening ribs 9 hold out against with the flange at side door plate about 1 two ends and weld；The right side of cross reinforcing 2
End withstands on vertical strengthening ribs 9 and is compacted by right pressing plate 7 and is welded with vertical strengthening ribs 9 and right pressing plate 7, and left end withstands on side
At flange on the left of door-plate 1 by left pressing plate 3 be compacted and with side door plate 1 on the left of and with side door plate 1 on the left of flange and pressing plate 3 weld
Connecing, right pressing plate 7 welds with vertical strengthening ribs 9, the flanging welded on the left of left pressing plate 3 and side door plate 1.
Deform in order to avoid the side door plate 1 that causes of welding and solder joint, described cross reinforcing 2 occurs in side door plate 1 surface
And the medial surface of vertical strengthening ribs 9 and side door plate 1 is all gluedd joint by structure glue.
Further, described structure glue is adopted as the TS830 type structure glue of Tianshan Mountains, Beijing new material technology company limited, should
Structure glue has high intensity (13MPa), big viscosity (about 200000mPa s, do not flow), shorter hardening time, (10 minutes preliminary
Solidification), acidproof (PH1-2 environment), alkaline-resisting (PH12-14 environment), high temperature resistant (180 DEG C-200 DEG C, 30 minutes), aging resistance (20
Year long duration test), (13 sample fatigue tests, mean stress is 7.7MPa situation to endurance, and the endurance obtained is
4.6MPa, standard deviation is 1MPa) etc. feature, it is ensured that the structural strength of side door plate and useful life longevity.
Further, the quantity of described cross reinforcing 2 is 2, and the two be arranged in parallel.
Further, vertical strengthening ribs 9 is provided with die mould protruding, is welded with hinge 8 at die mould high spot.
Further, it is provided with die mould depression in the left side of side door plate 1, is welded with door lock 4 at die mould recess.
