Abstract

The utility model discloses an equivalent-hole-group drilling mould suitable for an ultra-long H-shaped steel flange plate. The equivalent-hole-group drilling mould is used for gas chamber stand column hole machining. The equivalent-hole-group drilling mould comprises a U-type drill jig with two peepholes, drill sleeves, locating pin shafts and adjusting bolts. Firstly, four locating holes of a starting point are manually located in a stand column body and are drilled, a central line of the stand column flange plate is distinguished through a marking pin, the U-type drill jig with the two peepholes is placed on the stand column body, it is ensured that the central line of the U-type drill jig coincides with the central line of the stand column body through V-type locating grooves in the two peepholes, the front portion and the lower portion of the U-type drill jig are located through the locating pin shafts, the left portion and the right portion of the U-type drill jig are located through the adjusting bolts, and hole drilling is carried out through the drill sleeves. When the next group of holes is drilled, the U-type drill jig is moved in a sliding mode and is fixed in drilled holes through the locating pin shafts, and the rest can be drilled in the same way.

Description

One is applicable to hole group's clamping fixture for drillings such as overlength H shaped steel flange plate

Technical field

The utility model relates to the overlength H shaped steel flange plate clamping fixture for drilling of a kind of Kong Qun of grade, is applicable to gas chamber column drilling equipment, belongs to non-standard equipment and makes field.

Technical background

On the every joint column of gas chamber flange plate, there are the some groups of Kong Qun that repeat, normally utilize artificial line boring, this method, borehole accuracy is difficult to guarantee, and labour intensity is large, and efficiency of construction is low, and quality and safety can not well be ensured.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, easy to operate, and highly versatile is safe and reliable, has realized the clamping fixture for drilling of Reusability.

The purpose of this utility model is realized by following mode:

The utility model comprises U-shaped drill jig, drill bushing, alignment pin, the adjusting bolt with two peep-holes, it is characterized in that: U-shaped drill jig is to add and form with steel plate machine, after machining, on U-shaped drill jig, plane is accurately holed and is bumped into drill bushing, processes two Long Circle peep-holes corresponding U-shaped drill jig center line at two V-type locating slots of peep-hole inner side processing simultaneously; Respectively process two in U-shaped drill jig both sides for connecting the internal thread hole of adjusting bolt.Processing alignment pin, itself and drill bushing hole interference fits.

The utility model has the advantages that: reduce people's job number hole, locate convenient accurately, bolt hole machining accuracy is high, raise labour efficiency, and ensured construction quality.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the A-A profile of Fig. 1;

Fig. 3 is use state reference map of the present utility model.

Detailed description of the invention

With reference to accompanying

drawing

1,2,3, the utility model comprises U-shaped drill jig 1, drill bushing 2, adjusting bolt 3, the alignment pin 4 with two peep-holes, and concrete each parts embodiment is as follows:

First go out 4 locating holes of starting point and bored at column body 5 left-hand seat job numbers, then separate column flange plate center line with scriber, to be placed on column body 5 with the U-shaped drill jig 1 of two peep-holes, determine that by the V-type locating slot on two peep-holes U-shaped drill jig 1 center line overlaps with the center line of column body 5, carry out the location, front and back of U-shaped drill jig 1 by alignment pin 4, carry out the location, left and right of U-shaped drill jig 1 by adjusting bolt 3, hole by drill bushing 2.While boring next group hole, the U-shaped drill jig 1 of slippage, is fixed on the hole of having bored, by that analogy by alignment pin 4.

Facts have proved and utilize the method, novel, quick, reliable, can greatly improve drilling precision, shorten the construction period, increase work efficiency, obtain good effect.

Claims

1. one kind is waited the overlength H shaped steel flange plate clamping fixture for drilling of Kong Qun, mainly comprise U-shaped drill jig, drill bushing, alignment pin, adjusting bolt with two peep-holes, it is characterized in that: on U-shaped drill jig, process two Long Circle peep-holes corresponding U-shaped drill jig center line at two V-type locating slots of peep-hole inner side processing, on U-shaped drill jig, plane is accurately holed and is bumped into drill bushing, respectively process two in U-shaped drill jig two sides for connecting the internal thread hole of adjusting bolt, alignment pin and drill bushing hole interference fits.
