Description

[Detailed Description of the Invention] When making a liner plate, conventionally! i),′! I
i Specified pitch C4 for the arcuate fit (7 tsunji) of the Kasuri part
! Drill a bolt insertion hole for each bolt with R.

+z), Drill all the holes for inserting the bolts in the shape of a circle *mK at once. Move the above-mentioned connected molds into a predetermined arc shape and form an arc *tiitr
Conventionally, bolt insertion holes are drilled in the 7 flange of the liner plate by the above-mentioned method, so the arcuate radius of the flange changes. Since the interval changes every time the operation is done, the operating means is time-consuming.We have removed the above-mentioned drawbacks of the previous Rushin JVs and simplified the operating means as much as possible. The purpose of the present invention is to increase productivity and provide the product to the home at a low cost.
Make the pitch to the specified length, make the second pitch unreadable by the NNS device, drill two holes in one pitch, and make one pitch in the first pitch (
! Continuously perform operations to pierce the hole] It)l
Sequentially perform the apertures for the route, and the length of the arc on the above-mentioned arc.

The error in the length of the liner plate should be absorbed by the difference in the inner and outer diameters of the bolt insertion hole and *incoming melt. 11) is an arcuate curved liner play),
Tel should be 7 lunges for 11IwIl on that side.
When drilling a predetermined tightening hole in
n;g Regulate by having the device read it.

Then, the above operation is repeated and successively performed on the surface of the bolt insertion hole (set of holes ＼7 langes of the liner plate) specified in the above-mentioned drilling regulation rfJ.

The bolt insertion hole to be drilled in the above 7 langes IiK (the diameter of the set is slightly larger than the diameter of the bolt (4) (wJ4 is keeled, the difference is usually about $1-5 mm), and the hole for a flange such as a liner plate. is the length of Pitchia's arc6)
The difference between 6) and the length of the arcuate technique is 0.
The flange of the flange IK, for example, 15'F, is 3mm pre-grade - therefore the linerp V,) is made with regular drilling at 1 meter intervals, IA, i pitch ■ n, n, gllt.
If you read it by regulating it and drilling it, you can sequentially absorb the difference in deafness between the bolt and the bolt insertion hole on the flange surface. After tightening the bolts, the difference between the arc length and the cod length as above is I!, considering the length of the liner plate. Continue to overlap and tighten the two joint surfaces without causing any hindrance (the intended tightening can complete the operation). I! Continuation 7 Drill the required connection tightening holes in the langes, and use conventional drilling means to drill holes of approximately the same length as the holes 9)//[<In addition, each hole*@ tvy jointed into a shape, and then drilled bolt insertion holes at a predetermined interval on the W surface, which was made into a predetermined arc shape.
It has the characteristics of simplifying the operating means, improving the sound quality, and making it available to consumers at low cost.

The drawing W/A#L or explanatory drawing WIJ shows an example of the dormitory according to the present invention. Fig. 1 is a front view of the trunk with the liner plate used in the horizontal shaft rf4, and vz drawing is the contact! ! This is a partially enlarged perspective view of an explanatory diagram for drilling a 7-flange bolt insertion hole for *jFl.

(The end is the bolt insertion hole, f4) - M - Tightening port, (5
