を目的とする。In fuel tanks, hydraulic oil tanks, etc. mounted on construction machines such as hydraulic excavators, oil pipes connected to the tanks have flexibility, so that the tank can be easily assembled to the vehicle body more easily than in the past. In order to do so, a plurality of bolt holes opened in the tank mounting seat of the vehicle body and the seat plate fitting of the tank have been set to a loose fit fit with the tightening bolt. However, in a construction machine, an assembly position accuracy member that requires distance accuracy from a predetermined reference point of the vehicle body may be provided in the tank. In this case, the mounting position error of the tank with respect to the vehicle body was caused by the loose engagement of the bolts. An object of the present invention is to provide a mounting method capable of minimizing a mounting position error of a tank with respect to a vehicle body.

付けることができる。Next, the operation of the mounting method of the present invention will be described. In the present invention, since the swing center O of the swing body of the hydraulic excavator is set as the reference point, the reference point for the most accurate vehicle body assembly can be set regardless of the manufacturing error of each part of the vehicle body structure. Since the distance R on the horizontal projection plane between the turning center O and the vehicle body side reference hole 14 opened in the tank mounting seat 8 of the frame 7 is set to a dimension having accuracy, the vehicle body side reference hole 14 is It is possible to set the distance (that is, the distance R) between the tank side reference screw hole 18 to which the bolt is tightened and the turning center O to a dimension having accuracy. As shown in FIG. 5, the tank side reference screw hole 18 (screw hole diameter is the same as bolt diameter dM, for example, 16
The fitting of the bolt 27 that is screwed into the vehicle body side reference hole 14 (hole diameter is D 1 but is Φ16.5, for example) is set to be a sliding fit having a predetermined small gap (for example, 0.5 mm). . As a result, the tank side reference screw hole 18
And the hole center of the vehicle body side reference hole 14 can be made to match substantially exactly. Further, as shown in FIGS. 6 and 7, the bolt holes 13, 19 and 20 (all of which have a diameter of D 2 but are, for example, φ22) other than the vehicle body side reference hole 14 are loosely joined (gap). Is set to, for example, 6 mm), so that bolts 26, 28 and 29 can be easily inserted and tightened into the bolt holes 13, 19 and 20, respectively.

かなり小さく抑えることができる。Next, FIG. 9 is a plan view of essential parts showing the positional relationship between the fuel tank 6 and the bolts 28, 29 for tightening the fuel tank 6. In the present invention, when the guard mounting bracket 23 that requires the distance accuracy from the turning center O (the dimensional accuracy of the distance R x shown in FIG. 9) is provided on the upper surface portion of the fuel tank 6, the bolt screw holes of the guard mounting bracket 23 are provided. 25
And the distance Q on the horizontal projection plane between the tank side reference screw hole 18 and the tank side reference screw hole 18 is set to a dimension having accuracy. In this case, the tank side reference screw hole 18 includes another screw hole 18, a bolt hole 19 and 20 (shown in FIG. 3), the hole at the position closest to the bolt screw hole 25 of the guard mounting bracket 23 is selected. Therefore, as shown in FIG. 9, a gap S between the inner peripheral portion of the bolt hole 19 and the outer peripheral portion of the bolt 28 of the seat plate fitting 12 (the difference between the hole diameter D 2 of the bolt hole 19 and the bolt diameter dM shown in FIG. For example, even if the mounting rotation error of the fuel tank 6 is caused by the angle Δθ due to (6 mm), from the vehicle body side reference hole 14 (the tank side reference screw hole 18 is also substantially concentric with the vehicle body side reference hole 14). Since the distance L to the bolt hole 19 is considerably larger than the distance Q, the mounting position error of the guard mounting bracket 23 can be suppressed to be much smaller than the gap S.

ることは当然である。According to the present invention, the center of rotation of the revolving superstructure provided on the upper part of the traveling body such as the construction machine and the working vehicle is set as the reference point. It can be used as a reference point for accurate vehicle body assembly. Since the distance on the horizontal projection plane between the reference point and the vehicle body side reference hole opened in the tank mounting seat of the vehicle body is set to a dimension with accuracy, the tank to be bolted to the vehicle body side reference hole is set. The distance between the tank side reference hole of the seat plate fitting and the reference point can be set to a dimension having accuracy. In addition, the fitting of bolts to the tank side reference point and the vehicle body side reference hole was set to sliding with a predetermined small gap, and the bolt holes other than the reference holes were set to loose fitting fits with a large gap. The hole centers of the side reference hole and the vehicle body side reference hole can be substantially exactly matched, and bolts can be easily inserted and tightened in bolt holes other than the reference holes. Further, when providing the assembly position accuracy member that requires the distance accuracy from the reference point in the tank, the distance between the assembly position accuracy member and the tank side reference hole is set to a dimension having accuracy and the assembly position accuracy member is set. Since the bolt hole or bolt screw hole opened in the seat plate fitting at a distance close to the accuracy member is set as the tank side reference hole, the mounting position error of the assembly position accuracy member is It can be kept much smaller than the clearance between the bolt holes and the bolts. Therefore, by implementing the tank mounting method of the present invention, not only the mounting accuracy of mounting the tank itself to the vehicle body, but also the distance accuracy from the vehicle body reference point of the assembly position accuracy member provided in the tank can be secured, In this regard, the assemblability of the vehicle body structure can be improved. The present invention is not limited to the fuel tank, and it goes without saying that it can be applied to various types of tanks such as a hydraulic oil tank.
