Abstract

The utility model provides a main machine centering drill mold comprising a solid drill mold frame formed by a transverse angle steel and a longitudinal angle steel and a plurality of positioning holes of which sizes and positions are all corresponding to the screw holes of the bottom feet of a main machine and the bolt holes used for adjusting the height of the drill mold. The front and the back central positions of the drill mold are respectively provided with a small slot steel respectively provided with a base point position determining the axial corresponding position of the drill mold on the steel wire central line and also the position is corresponding to the positions of the fly wheel center and the supporting leg bolt hole of the main machine. The main machine centering drill mold of the utility model can replace main machine centering and main machine base hole drilling. The construction on ship is convenient and the main machine centering, the main machine cushion block positioning, the main machine base hole drilling and the main machine cushion block mending can be finished before the main machine hoisting.

Description

Main frame centering drill jig

Technical field

The utility model relates to a kind of main frame centering drill jig, is applicable to the installation of hanging that makes things convenient for main frame when building boats and ships, and the main frame that relates in particular to a kind of full circle swinging craft tug hangs installation.

Background technology

Shipyard hangs on the fixing link at main frame when building boats and ships, often finishes the centering of main frame by main frame itself, row's machine programs such as boring of main frame base, though this is traditional a kind of row's machine mode, in institute's shipbuilding oceangoing ship main frame increasing today, shortcoming also reveals gradually:

1, centering, the boring of main frame base, the main frame lower cushion block of finishing main frame strokes operations such as mill, and main frame will repeatedly lift.

2, construction period is longer.

3, the required large lifting equipment time that takies longer, have a strong impact on the shipyard scheduling of production.

When 4, constructing, worker's environment of living in is abominable, and the trouble free service difficulty is bigger, waste great amount of manpower and material resources, financial resources.

So how to make the repeatedly lifting of main frame become once lifting, shorten main frame and hang the installation cycle, just become the urgent problem that solves of needs.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of main frame centering drill jig that can replace main frame centering and the boring of main frame base of special use, the requirement easy construction of going on board, centering, main frame lower cushion block location, the boring of main frame base and the main frame lower cushion block that can finish main frame before the main frame lifting stroke operations such as mill.

In order to solve the problems of the technologies described above, the utility model has adopted following technical proposals: a kind of main frame centering drill jig, comprise a solid of forming by horizontal angle steel and sole bar angle the drill jig framework, comprising several big or small positions all with main frame footing screw locating hole and regulate the bolt hole of drill jig height one to one.Each channel bar of center before and after the drill jig, this channel bar is provided with a basic point position, and the relative axial position of drill jig at the steel wire center line determined in this position, and this position is corresponding with the flywheel center and the foundation bolt hole site of main frame.

Use main frame centering drill jig that following advantage is arranged:

1, finished main frame centering before the main frame lifting necessary operation is installed, the repeatedly lifting of main frame becomes once lifting.

2, shorten construction period 7 days.

3, reduce worker's labour intensity greatly, improved operating efficiency, for the worker provides good, a safe operating environment.

4, significantly reduced dependence to large lifting equipment, whole construction (calculating with two main frames of every ship) is reduced expenses about 50,000 yuan.

The specific embodiment

Main frame centering drill jig of the present utility model can reflect main frame footing screwhole position faithfully, the axial location of host crankshaft position of center line and main frame heart wheel.As Fig. 1; shown in 2: in this specific embodiment; this drill jig comprises that an appearance and size is δ=10; the drill jig framework 1 of L100 * L70; the both sides, front and back of this drill jig framework 1 are installed horizontal angle steel 2 and at its right and left sole bar angle 3 are installed; this horizontal angle steel is than the high about 3mm of sole bar angle (as shown in Figure 5); on dragon is dug, the drill jig baseplane is dug to required precision then; and on the horizontal angle steel 2 in front and back, pull out center 4; on sole bar angle 3, pull out the position line 5 of main frame screw; after line finishes; drill jig bores required locating hole 6 by drawing on boring machine; in this specific embodiment be 18 positions size all with main frame footing screw locating hole one to one, this drill jig also is provided with four bolts hole of four Height Adjustment bolts 7 and correspondence.Last drill jig assembly unit on platform, drill bushing is inlayed into drill jig, and spot welding, respectively weld a channel bar 9 according to main frame base 8 to the distance of crankshaft axis in center, drill jig rear and front end again, on front and back channel bar 9, respectively open wide 1.5mm, the breach 10 of dark 1.5mm is channel bar seam (as shown in Figure 4), and calculates drill jig in the channel bar seam of the flywheel end distance to main frame flywheel inner stopper.
