Yet the problem of existence is, the one, and torque amplification 101 is special-purpose, can't buy on market; The 2nd, the ratio of torque amplification 101 is less, and when needs dismounting nut 112, moment of torsion is large not, need to set up hydraulic tool and be used in conjunction with.
Summary of the invention
The object of the present invention is to provide a kind of nut dismounting tool, this dismantling device adopts general torque amplification, and multiplication factor can be selected as required, has easily bought on market; And it is lightweight, and is simple in structure.
In order to solve the problems of the technologies described above, a kind of nut dismounting tool of the present invention, the output shaft, nut spanner, the fixed sleeving that comprise torque amplification, torque amplification, also comprise shell connecting plate, connecting plate, connecting axle, torque amplification shell and shell connecting plate join, and output shaft and the connecting axle of torque amplification join; Shell connecting plate and connecting plate are flexibly connected, and connecting plate and nut spanner join, and fixed sleeving is socketed in nut spanner and joins with connecting axle.
As a modification of the present invention, described shell connecting plate and connecting plate are threaded connection.
Improve as the present invention is another kind of, this dismantling device also comprises middle connecting plate, and described shell connecting plate and connecting plate are flexibly connected middle connecting plate.
For the nut dismounting tool with middle connecting plate, this middle connecting plate and shell connecting plate are threaded connection, and are threaded connection with connecting plate.
For the nut dismounting tool with middle connecting plate, because the shell connecting plate of the torque amplification of buying back will could join with the connecting plate of nut spanner after repacking, after adopting such structure, only need the different middle connecting plate of repacking just can satisfy installation requirement, reduce modification difficulty, reduced the repacking time.
Further improve as the present invention, the output shaft of described torque amplification and connecting axle are matched in clearance; Described connecting plate and nut spanner are welded; Described fixed sleeving and connecting axle are matched in clearance or spline fitted; Described fixed sleeving and nut spanner are for being slidably connected.
In sum, a kind of nut dismounting tool of the present invention adopts general torque amplification, and multiplication factor can be selected as required, easily bought on market, and it is lightweight, and is simple in structure, easy accessibility.

The specific embodiment
Elaborate below in conjunction with two kinds of embodiments of accompanying drawing to a kind of nut dismounting tool of the present invention.
Show the nut dismounting tool of the first embodiment of the present invention at Fig. 1 and Fig. 2, comprise that wherein torque amplification 1, torque amplification 1 output shaft 2, connecting axle 6, combustion machine part (9,10,11,12) are not cut open for output shaft 2, shell connecting plate 3, connecting plate 4, connecting axle 6, nut spanner 7, the fixed sleeving 8(of torque amplification 1, torque amplification 1 in Fig. 1, Fig. 2).This torque amplification 1 shell is good for by pin with shell connecting plate 3 and is connected, and the output shaft 2 of described torque amplification 1 is matched in clearance (output shaft 2 mostly is square shape, so an end of connecting axle 6 has the groove of square shape to match with it) with connecting axle 6.Shell connecting plate 3 is connected by bolt 5 with connecting plate 4, and connecting plate 4 is welded with nut spanner 7.Connecting axle 6 be matched in clearance or spline fitted with fixed sleeving 8, does not relatively rotate and gets final product to reach output shaft 2 and fixed sleeving 8.Fixed sleeving 8 is inserted in nut spanner 7, and 7 of fixed sleeving 8 and nut spanners are for being slidably connected.Fixed sleeving 8 is fixed on combustion machine rotor axle 12 by bolt 5, nut 11 places that nut spanner 7 is aimed on the combustion machine.When driving torque amplifier 1, because the output shaft 2 of torque amplification 1 is fixing, its shell rotates and drives nut spanner 7 rotations, realizes the dismounting to nut 11.
After adopting the first nut dismounting tool of the present invention, because the torque amplification 1 that uses can be bought on market, solved the problem that in the prior art, torque amplification 101 is hard to buy, and in prior art, the enlargement ratio of torque amplification 101 is little, can because moment of torsion is large not, could dismantle and need to separately give hydraulic tool when needs dismounting nut 11.Can choose the torque amplification 1 of different enlargement ratios on market, solve the little problem of torque amplification 101 enlargement ratios in the prior art.
In the nut dismounting tool of the second embodiment of the present invention, except being provided with middle connecting plate 13 at shell connecting plate 3 and 4 of connecting plates, other are identical with nut dismounting tool structure in the first embodiment of the present invention.The nut dismounting tool of the second embodiment of the present invention has been shown in Fig. 3 and Fig. 4, and middle connecting plate 13 is located at 4 of shell connecting plate 3 and connecting plates, and is connected with connecting plate with shell connecting plate 3 and is connected (other existing connected modes also can) by bolt 5.Because torque amplification 1 structure of different amplification is different, the shell connecting plate 3 of the torque amplification 1 of at every turn buying back will could join with the connecting plate 4 of nut spanner 7 after repacking, and nut spanner 7 costs are relatively high, and is difficult for reequiping.After adopting the structure in the second embodiment, only need the different middle connecting plate 13 of repacking just can satisfy installation requirement.And, in use, as long as change just replaceable different torque amplification 1 of different middle connecting plates 13, so not only reduced modification difficulty, and reduced the repacking time.
In sum, a kind of nut dismounting tool of the present invention adopts general torque amplification, and multiplication factor can be selected as required, easily bought on market, and it is lightweight, and is simple in structure, easy disassembly.
The above has done detailed description to embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also make various variations under the prerequisite that does not break away from the utility model aim.
