Description

Be used for the boring moulding bed that pipe bores arbitrarily angled inclined hole

Technical field

The utility model relates to a kind of boring frock, particularly a kind ofly is used for the boring moulding bed that pipe bores arbitrarily angled inclined hole.

Background technology

In recent years, the continuous development of China's steel construction industry, various steel part emerge in an endless stream, and except that steel structure platform, steel ladder, are exactly the railing made of pipe or based on other tube construction of pipe in addition.This structure mainly contains following several form when connecting:

(1) connect with spherojoint, this syndeton is specious, but cost of manufacture is than higher, and production process is more complicated also, is exactly insufficient strength in addition, generally only is used in office building and relatively more exquisite public arena.

(2),, weld in that section both sides that do not disconnect again perpendicular to length direction earlier with after one section disconnection two sections pipes of the angled intersection that will connect.This connected mode is easy angles after its moulding of control when the two pipe angles of cut become 90 degree only, but then need and will do the otch model last hand cut of ruling again after the interface setting-out for two pipes that any angle intersects.Manufacture difficulty is bigger, and will consider distortion and distortion behind the rivet welding.

(3) based on the problem of above existence, what relatively be suitable for now is therein on one section pipe after the punching, again another section is passed from the hole, but the angle of cut is only limited to 90 degree, the perforate mode also adopts the punch press punching often, but general steel construction rivet welding workshop is not equipped with punch press, and the borehole conditions limitation is bigger again, not too is fit to large batch of workshop and makes.

Summary of the invention

The utility model provides a kind of boring moulding bed that pipe bores arbitrarily angled inclined hole that is used for for solving the technical problem that exists in the known technology, uses this moulding bed can use on the drilling machine processing pipe inclined hole at any angle easily.

The utility model for the technical scheme that solves the technical problem that exists in the known technology and take is: a kind ofly be used for the boring moulding bed that pipe bores arbitrarily angled inclined hole, comprise base, be connected with riser on the described base, described riser is provided with hollow out circular arc slideway and angle scale; Be hinged with down locating clip on the described base, be coated with double-screw bolt in the hollow out circular arc slideway of described riser, an end of described double-screw bolt is the stiff end that is fixed on the locating clip, and the other end is a free end, described free end is equipped with nut, and described nut is positioned at the outside of riser; Be separately installed with holding screw on the described upper and lower locating clip, described going up on the locating clip is connected with pointer, be connected with the drill positioning device between upper and lower locating clip on the described base, described drill positioning device comprises the bearing and the abutment sleeve that be seated in bearing in affixed with base.

The body of described upper and lower locating clip is a pipe.

Between described nut and the riser pad is installed.

Described nut is a dish shape nut.

Described angle scale is riveted on the riser.

Described abutment sleeve is made by brass

Advantage and the good effect that the utlity model has are: easy and simple to handle, can produce in batches for the boring of pipe, and on the basis that has reduced working strength of workers, raise labour efficiency greatly; Be fit to promote the use of.Simple in structure, be easy to processing and fabricating.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1～Figure 11, the utility model mainly is made of following several parts:

(1) base 2, are connected with riser 1 on the base 2, have hollow out circular arc slideway on the riser 1 and are used for adjusting angle, also play locating clip 4 and following locating clip 8 in support angle scale 3, the connection.Be coated with double-screw bolt 11 in the hollow out circular arc slideway of riser 1, an end of double-screw bolt 11 is the stiff end that is fixed on the locating clip 4, and the other end is a free end, free end is equipped with nut 12, nut 12 is positioned at the outside of riser 1, and nut 12 can adopt dish shape nut, to make things convenient for it to unclamp and to tighten; Best shimming 13 between nut 12 and the riser 1 is with the contact area of increase with riser 1.On the following locating clip 8 tightening jackscrew 9 is installed, on the last locating clip 4 tightening jackscrew 10 is installed, be used for holding out against boring pipe 14, so that boring pipe 14 relative its do not slide.Following locating clip 8 couples together with bearing pin of base 1 usefulness, and pipe can move in a circle around bearing pin like this, and is fixing after the adjustment angle.The body of upper and lower locating

clip

4,8 is a pipe, with the support of convenient boring pipe 14 and fixing.
