Abstract
The present invention relates to a kind of middle pin hole sticking board type mental rocking arm, plate-side plate welding is close to by inner side pasting board, outside pasting board by upper sealing plate, lower sealing plate, two pieces side plate by a box rocking arm being welded to form, at rocking arm mesoporous and is formed.In rocking arm at pin hole with pasting board mode instead of it is original wear axis mode, make in rocking arm that stress effective cross-section is widened at pin hole, weld seam stress is reduced, and meets the intensity requirement of rocking arm, also saves the cost of side plate thickness of slab thickening.
Description
Technical field
The present invention relates to a kind of Constructional Machinery, more particularly to a kind of middle pin hole sticking board type mental rocking arm.
Background technology
In loading machine operation process, equipment is stress component the most severe.And rotating bucket turn up in operation process
When, the active force that equipment has been given play to also is the largest, it is clear that the main bearing member rocking arm of rotating bucket mechanism be also subjected to compared with
Big load.And the weakest position of whole rocker arm strength is exactly in rocking arm at pin hole, due to the influence of mechanical interferences, in rocking arm
Section at pin hole can not increase, and side plate thickness of slab, which thickeies, is also significantly increased cost.
The content of the invention
It is an object of the invention to improve the structure type of rocking arm, its structural strength is improved.
Specifically, there is provided a kind of middle pin hole sticking board type mental rocking arm, passes through welding by upper sealing plate, lower sealing plate, two pieces side plate
One box rocking arm of composition, is close to plate-side plate welding by inner side pasting board, outside pasting board at rocking arm mesoporous and forms.
The beneficial effects of the invention are as follows：Due to the adoption of the above technical scheme, instead of in rocking arm at pin hole with pasting board mode
Originally wear axis mode, make in rocking arm that stress effective cross-section is widened at pin hole, weld seam stress is reduced, and the intensity for meeting rocking arm will
Ask, also save the cost of side plate thickness of slab thickening.
Brief description of the drawings
Fig. 1 is the structure diagram of middle pin hole sticking board type mental rocking arm of the present invention.
Embodiment
The present invention is described further with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of middle pin hole sticking board type mental rocking arm, side plate 3 and pasting board 5, pasting board 7, pasting board 9 are bolted together,
It is welded into right plate component；Side plate and pasting board are bolted together, are welded into left plate component, since pasting board is thicker at mesoporous,
Weld seam fillet weld size is larger, and welding deformation is also big, so need to flatten left and right side plate component, is become with eliminating the welding at mesoporous
Shape, facilitates the assembly of upper sealing plate 1, lower sealing plate 2；Upper sealing plate 1, lower sealing plate 2 are bending plates；By left plate component, right plate group
The alignment of part hole position, upper sealing plate 1, lower sealing plate 2 are supported on left plate component, among right plate component, by left plate component, right plate
Component and upper sealing plate 1, the assembly of lower sealing plate 2, the basic structure for being welded into one box rocking arm of composition；In box rocking arm basic structure
Pasting board 6, pasting board 4, pasting board 8 are formed the present invention in left and right outside welding
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
All any modification, equivalent and improvement made within principle etc., should all be included in the protection scope of the present invention.
Claims (1)
- A kind of 1. middle pin hole sticking board type mental rocking arm, it is characterised in that：By upper sealing plate, lower sealing plate, two pieces side plate by being welded to form One box rocking arm, is close to plate-side plate welding by inner side pasting board, outside pasting board at rocking arm mesoporous and forms.
