Abstract

The invention relates to the field of machinery, and discloses a compact multi-hole positioning tool which comprises a plurality of positioning pin shafts, the outer diameter of each positioning pin shaft is matched with an inner hole of a conical cylinder structure of an upper-layer workpiece, and the plurality of positioning pin shafts are jointly connected to a positioning mounting ring. The axial length of the positioning pin shaft is not less than the stacking height of the upper-layer workpiece and the lower-layer workpiece; the shaft hole penetrates through the positioning pin shaft in the axis direction of the positioning pin shaft, the inner diameter of the shaft hole is matched with the diameter of an anode column arranged on the workpiece on the lowermost layer, and the height of the anode column is not lower than the stacking height of all the workpieces. According to the assembly precision of the large-scale structural member, a proper fit clearance is designed for the positioning tool, and the requirement for the micron-scale or millimeter-scale coaxiality assembly precision of the large-scale structural member can be met.

Description

technical field

[0001] The invention relates to the field of machinery, in particular to a compact porous positioning tool. Background technique

[0002] A large-scale magnetically insulated transmission line is composed of 5 workpieces, each of which is a stainless steel thin-walled cone structure. There are inner holes running through the stainless steel thin-walled cone up and down. The bottom diameter of each cone is about 3 meters, and the height (0.5 ~1.8) meters, and each workpiece weighs about 1 ton. The lowermost workpiece has an anode column connected by threads in the vertical direction. The anode column passes through the inner hole of the second layer of workpieces, the third The inner hole of the workpiece on the fourth layer, the inner hole of the workpiece on the fourth layer, and the inner hole of the workpiece on the fifth layer. Finally, the anode column and the workpiece on the fifth layer are fixed by screwing the top of the workpiece on the fifth layer ...

Examples

Embodiment

[0036] like Figure 1-5 shown, a compact multi-hole positioning tool comprising:

[0037] The positioning pin shaft 1, the outer diameter of the positioning pin shaft 1 matches the inner hole of the conical cylinder structure of the upper workpiece 2, the positioning pin shaft 1 is provided with a plurality of, and the plurality of positioning pin shafts 1 are connected together in the positioning on the mounting ring 3, and the axial length of the positioning pin 1 is not less than the stacking height of the upper workpiece 2 and the lower workpiece 2a stacked;

[0038] The shaft hole 4 is provided through the positioning pin shaft 1 along the axial direction of the positioning pin shaft 1 , and the inner diameter of the shaft hole 4 matches the diameter of the anode column 2b arranged on the lowermost workpiece.

[0039] The anode column can be screwed into the inner cylinder of the lowermost workpiece by threading, and finally a nut is installed on the outer thread provide...
