Description
Technical Field
The utility model relates to an integrative frock of right/left front welding stent of loader engine belongs to engineering machine tool technical field.
Background
The left and right front welding brackets of the loader engine are important bearing parts of the loader engine, and are mainly used for connecting an engine system and a rear frame system and transmitting the dead weight of the engine to a rear frame through the engine welding brackets. Therefore, the engine welding bracket is stressed greatly, and has high requirements on welding precision and quality.
As shown in figures 1 and 2, the left/right front welding bracket of the loader engine is mainly formed by assembling and welding a bent plate 1, a rib plate 2 and a mounting plate 3. A traditional positioning tool (shown in figure 3) is adopted to fix the bent plate 1 and the rib plate 2 through 2 positioning pin shafts respectively, and then the mounting plate is placed on the inner side of the notch of the bent plate 1 to be tightly leaned to be welded. The traditional positioning tool is adopted for positioning, assembling and welding, so that the welding size deviation is large easily caused due to low positioning precision, the welding quality is difficult to guarantee, the welding requirements of drawings are difficult to meet, and the like; meanwhile, the loader engine is heavy and starts to work, the welding positions of the left and right front welding supports of the engine are prone to cracking when the stress is uneven due to large vibration, and even the mounting plate 3 is prone to impact and crack at the notch of the bent plate 1, so that great risk is brought to work guarantee of the whole loader. Therefore, a new tool integrating left and right front welding brackets of a loader engine needs to be developed to solve the problems.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: how to prevent the large welding size deviation caused by inaccurate positioning of the left and right front welding brackets of the engine, the difficulty in ensuring the welding quality, the non-conformity with the welding requirements of drawings and the like; meanwhile, the loader engine is heavy and starts to work, so that the welding positions of the left and right front welding supports of the engine are prone to cracking when the stress is uneven due to large vibration, and even the mounting plate is prone to cracking due to impact on the notch of the bent plate.
In order to solve the technical problem, the technical scheme of the utility model a loader engine left/right front welding stent integrative frock is provided, its characterized in that, including the locating plate that is used for fixing a position the bent plate, be equipped with the location curb plate that is used for fixing a position the gusset on the locating plate, the both sides of locating plate are equipped with the bottom plate that is used for the location mounting panel.
Preferably, the bottom plate, the positioning plate and the positioning side plate are respectively provided with a shaft hole, a positioning side plate positioning pin shaft I is connected with the rib plate, the positioning plate is connected with the bent plate through a positioning pin shaft II, and the bottom plate is connected with the mounting plate through a positioning pin shaft III. The tool positions all materials of the left/right front supports of the engine of the loader through the positioning pin shafts, so that the assembly precision requirement is improved, and the welding quality basic requirement is ensured; meanwhile, the tool is of a bilateral symmetry structure, the tool does not need to be replaced, and the left/right front welding bracket of the engine of the loader can be assembled and welded in the tool in a positioning mode.
More preferably, the inner walls of all the shaft holes are of stepped structures, and the structures of the corresponding positioning pin shafts are matched with the stepped structures.
The utility model relates to a rationally, sturdy structure assembles the precision height and easy and simple to handle, and each material of loader engine left and right front support has all improved the required precision of assembling through the locating pin axle location, has guaranteed welding quality basic requirement, improves welding quality, avoids welding seam fracture and mounting panel to bent plate breach department striking fracture.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
Examples
The utility model provides a pair of integrative frock of right/left front welding stent of loader engine is shown in fig. 4, an integrative frock of front welding stent about loader engine, a serial communication port, including being used for fixing a position locating plate 5 of bent plate 1, be equipped with the location curb plate 6 that is used for fixing a position gusset 2 on the locating plate 5, the both sides of locating plate 5 are equipped with bottom plate 4 that is used for fixing a position mounting panel 3. Shaft holes are respectively formed in the bottom plate 4, the positioning plate 5 and the positioning side plate 6, a positioning pin shaft I7 of the positioning side plate 6 is connected with the rib plate 2, the positioning plate 5 is connected with the bent plate 1 through a positioning pin shaft II 8, and the bottom plate 4 is connected with the mounting plate 3 through a positioning pin shaft III 9. The inner walls of all the shaft holes are of stepped structures, and the corresponding positioning pin shafts are matched with the stepped structures. The tool positions all materials of the left/right front supports of the engine of the loader through the positioning pin shafts, so that the assembly precision requirement is improved, and the welding quality basic requirement is ensured; meanwhile, the tool is of a bilateral symmetry structure, the tool does not need to be replaced, and the left/right front welding bracket of the engine of the loader can be assembled and welded in the tool in a positioning mode.
When the tool is used for the left front welding bracket of the loader engine, as shown in fig. 5, the bent plate 1 is positioned through a second positioning pin shaft 8 and fixed on the positioning plate 5; the rib plate 2 is fixedly positioned on the positioning side plate 6 through a positioning pin shaft I7; the mounting plate 3 is positioned by a positioning pin shaft III 9 and fixed on the bottom plate 4. The left/right front welding support of the engine is fixed in a positioning mode through the positioning pin shaft, the assembling precision is improved, the welding quality is guaranteed, and the phenomenon that the welding line cracks due to inaccurate positioning size and even the installation plate 3 collides and cracks at the notch of the bent plate 1 is avoided.
