Abstract
The utility model relates to a pipe-shaped component circumferential drilling device which is characterized by comprising a base core consisting of a chassis and a core column, wherein a regular prism with a cylindrical hollow is sleeved on the core column, a ring-shaped gap capable of being inserted into a processed pipe-shaped component is arranged between the regular prism and the core column, the regular prism is connected onto the chassis through a bolt, each side wall of the regular prism is respectively provided with a drill hole corresponding to a to-be-processed hole position on the processed pipe-shaped component, a threaded hole is arranged on the axial direction on the end portion of the core column, and a pressing bolt penetrates through a pressing plate for covering the processed pipe-shaped component and then is screwed in the threaded hole. A through gap is arranged downwards from the position of the threaded hole which is penetrated through by the pressing bolt, and the width of the gap is bigger than the bar diameter of the pressing bolt. The pipe-shaped component circumferential drilling device can finish manufacturing a plurality of holes in circumference direction through one clamping, has convenient operation and accurate locating, greatly improves the processing efficiency, and can be widely applied in the circumference drill hole manufacture process of the pipe-shaped components.
Description
Technical field
The utility model relates to a kind of drilling equipment, particularly about a kind of circumferential drilling equipment of pipe-shaped parts.
Background technology
In machine industry, there are many tubular workpieces such as the gear ring of using on the internal combustion engine oil pump, just need upwards evenly hole in its circumferential boring in the week of its outer wall.At present circumferential bore modes that adopt are to tighten with scroll chuck more, connect dividing head and be rotated boring, to reach the circumferential purpose that waits branch borehole, but this processing mode complex operation, make workpiece deformation easily, and need scroll chuck, the first-class expensive device secondary process of calibration, have a lot of problems.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides the circumferential drilling equipment of a kind of time saving and energy saving, easy to process pipe-shaped parts.
For achieving the above object, the utility model is taked following technical scheme: the circumferential drilling equipment of a kind of pipe-shaped parts, it is characterized in that: it comprises an end core of being made up of chassis and stem stem, one regular prism with cylinder type hollow is set on the described stem stem, and has the annular gap that to insert processed tubular part between described regular prism and the described stem stem, described regular prism is connected on the described chassis by bolt, be respectively arranged with on each sidewall of described regular prism with processed tubular part on the corresponding boring in position, hole to be processed, the end axis of described stem stem is to being provided with a screwed hole, one hold-down bolt pass one be used to cover the pressing plate of establishing described processed tubular part after, be screwed in the described screwed hole.
Described hollow regular prism is one of positive tetrahedron, regular hexahedron, regular octahedron or other any regular polygon shapes.
Be fitted with drill bushing in the described boring on each sidewall of described regular prism.
On described pressing plate, the screwed hole that passes from described hold-down bolt offers a gap that connects downwards, and the width of described gap is greater than the bar footpath of described hold-down bolt.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model is owing to be provided with an end core with stem stem, the regular prism that has a plurality of planes in stem stem outside sheathed, has the annular gap between stem stem and the regular prism, therefore workpiece can be located in the annular gap between stem stem and the regular prism, the boring of offering on each side by regular prism makes drill bit by the positioning and drilling of holing, position processing, improved machining accuracy.2, therefore the utility model can will be pressed on the annular gap for the processing pipe fitting from end face by pressing plate owing to be tightened on the stem stem after adopting a hold-down bolt to pass a pressing plate from the outside, the restriction workpiece diametrically rock and axially on play.3, the utility model is provided with gap in pressing plate bottom, when hold-down bolt is back-outed, can conveniently take off, and the utility model convenient mounting and clamping has improved working (machining) efficiency greatly, can be widely used in the circumferential boring process of various tubular workpieces.

The specific embodiment
Below in conjunction with embodiment, the utility model is described in detail.
As Fig. 1～shown in Figure 3, the utility model comprises an end core 1, and end core 1 has chassis 2 and stem stem 3, and chassis 2 and stem stem 3 both can integral productions, also can the split production combination install.Stem stem 3 is a cylinder, and it is columniform regular prism 5 that an inner ring is set in stem stem 3 outsides, with a plurality of bolts 4 regular prism 5 is fixed on the chassis 2.Leave an annular gap between stem stem 3 and the regular prism 5, this annular gap be able to make processed tubular workpiece 6 insert.On each sidewall of regular prism 5, be respectively arranged with processed tubular workpiece 6 and treat the through hole that bore position is corresponding, be respectively arranged with a drill bushing that shields 7 in each through hole.Center, end from stem stem 3, inwardly offer a screwed hole 8, other has a hold-down bolt 9, pass a pressing plate 10 after, be screwed onto in the screwed hole 8, make the end face of pressing plate 10 can be in the annular gap of processed tubular workpiece 6 roof pressures between stem stem 3 and regular prism 5.As shown in Figure 3, on the pressing plate 10, offer a gap 11 that connects downwards from the through hole that wears hold-down bolt 9, the width of gap 11 is more than or equal to the bar portion diameter of hold-down bolt 9, like this, when hold-down bolt 9 takes out from screwed hole 8, just can be easily take out from gap 11, and the pressing plate 10 of will whole hold-down bolt 9 not back-outing.
During work, in the annular gap between processed tubular workpiece 6 insertion stem stems 3 and the regular prism 5, be inserted into 2 bottoms, chassis always; Then pressing plate 10 is covered processed tubular workpiece 6, and after passing pressing plate 10 with hold-down bolt 9, be tightened in the screwed hole 8 of stem stem 3, thus processed tubular workpiece 6 is fixing.Can be after the installation with arbitrary and lathe table top location of regular prism 5, the drill bushing 7 with the relative one side with table top of drill bit punches then.After a hole drill is intact, more successively with regular prism 5 upset location, in another face boring, until finishing all circumferentially boring.
