Abstract
The utility model relates to a special tool for screwing up a small round nut of a bulldozer. The special tool for screwing up the small round nut comprises a sleeve and a tool body and is characterized in that the outer part of the tool body is a cylinder and the inside of the tool body is provided with two stepped holes; the central position of the upper plane of the cylinder is provided with a round hole and the lower plane of the cylinder is provided with four claws with the same size through milling; the four claws are distributed on the periphery of the lower plane uniformly; and the lower planes of the four claws are necessarily perpendicular to the upper plane of the cylinder. The sleeve is inserted in the round hole in the upper portion of the tool body vertically and is welded with the tool body, with a welding line being smooth and flat, and thus the sleeve and the tool body form a whole body. The special tool can be used for screwing up the small round nut through an air wrench and has the advantages that the labor intensity is reduced, time is saved, working efficiency is improved, and the small round nut is prevented from damage.
Description
Technical field:
The utility model belongs to engineering machinery field, relates in particular to a kind of specific purpose tool that screws little round nut of using on the bull-dozer.
Technical background:
In the process of assembling bull-dozer, it is the little round nut of GB810-88 that a kind of piece number is arranged, and relies on chisel to screw by manpower fully when original the installation, and labour intensity is large, and efficiency of assembling is low, and very easily causes the roundlet nut to damage.
The utility model content:
The utility model has been studied a kind of specific purpose tool that screws little round nut for solving above technical barrier, utilizes pneumatic impact spanner to screw.
The utility model for achieving the above object, by the following technical solutions: the specific purpose tool that originally screws little round nut comprises sleeve, tool body two parts.Its architectural characteristic is: the tool body outside is a cylinder, there are two shoulder holes inside, the centre bit on plane is equipped with a circular hole on the cylinder, lower plane mills four identical pawls of size, these four pawls are evenly distributed on the circumference, will guarantee that simultaneously the lower plane of four pawls is vertical with cylindrical upper plane.Sleeve vertically is inserted in the circular hole above the tool body, welds, and requires smooth welding joint smooth, and this moment, sleeve and tool body became an integral body.During work, this Special rotary clamping tool relies on four pawls of an end to be connected with four breach insertions of little round nut, screws little round nut by sleeve with pneumatic impact spanner.
The beneficial effects of the utility model: this specific purpose tool used pneumatic impact spanner to screw, and had not only reduced labour intensity, had saved the time, had improved operating efficiency, and avoided damaging little round nut
Description of drawings:
Accompanying drawing 1 is the specific purpose tool that screws little round nut.
1, sleeve 2, tool body
Accompanying drawing 2 is roundlet nut schematic diagrames.
The specific embodiment:
During work, four pawls on the tool body 2 of this specific purpose tool are inserted with four breach of little round nut shown in Figure 2 is connected, then pneumatic impact spanner is inserted in the sleeve 1 of Fig. 1, the startup pneumatic impact spanner screws little round nut.
The above is exactly preferred embodiment of the present utility model, and every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment does.
