Description
Technical field
The present invention relates to a kind of boring device, particularly relate to the borer in a kind of hole, belong to Machining Technology field.
Background technology
In present metalworking field, boring work for two groups of even many group holes that axiality on same axis requires, owing to the amount of feeding of dynamic head main spindle is limited, so needs carry out location repeatedly and clamping to carry out boring when two groups of holes that distance is bigger, therefore the problem brought is exactly when converting blank position and clamping cutter again, the positioning datum of blank can produce deviation in this process, and the axiality that may result in two holes produces deviation.
Summary of the invention
The technical problem to be solved is to carry out boring and cause the defect that the axiality in hole is the highest for two groups of the most distant holes can not realize in prior art clamped one time location, it is provided that a kind of hole boring device.
For solving this technical problem, the invention provides a kind of hole boring device, including boring bar, cutterhead and unit head, described boring bar includes knife bar and extends knife bar, knife bar and prolongation knife bar are coupled by universal joint, and described cutterhead is connected by fixing groove single-blade boring cutter；
Extending knife bar to be arranged on two centre frames, described cutterhead is fixed on prolongation knife bar, and unit head is connected realization cutting and feed motion with knife bar；Or:
Increase centre frame, the quantity of cutterhead quantity to hole, extend knife bar to be arranged on multiple centre frame, multiple cutterheads are arranged on prolongation knife bar, unit head is connected realization cutting and feed motion with knife bar, adjust universal joint, ensure to extend knife bar axis consistent with work pieces process datum line so that extend first group of hole of knife bar axis consistent with work pieces process datum line with central point line at last group hole.
Described cutterhead is by upper and lower bipartition, and upper and lower two are bolted and are fixed on prolongation knife bar.
Beneficial effect: clamped one time of the present invention is fixed, can realize carrying out the hole more than two on an axis boring work, improve the machining accuracy of the several sets of apertures that on an axis, axiality had certain requirements, reduce production cost, save the duration, improve production efficiency and quality.

Detailed description of the invention
Below in conjunction with the accompanying drawings and the present invention is specifically described by embodiment.
Fig. 1 show the structural representation of the present invention.
The invention provides a kind of hole boring device, including boring bar, cutterhead and unit head.
Described boring bar includes knife bar 1 and extends knife bar 2.
Shown unit head is connected with knife bar 1, and the effect of knife bar 1 is used for transmitting the cutting force of unit head, it is achieved cutting and feed motion.
Described knife bar 1 and prolongation knife bar 2 are coupled by universal joint 3, the effect of universal joint 3 can be trickle adjust knife bar 1 and the angle extending knife bar 2, not only ensure to extend knife bar 2 when cutting in the concordance of datum axis, moreover it is possible to make it receive the cutting force that unit head is delivered to.
Extending knife bar 2 to be arranged on two centre frames 5, centre frame 5 is used for stability and the accuracy ensureing to extend knife bar 2.
Fig. 2 show the assembling schematic diagram of cutterhead of the present invention.
Being connected by fixing groove on described cutterhead 4 has single-blade boring cutter 6, cutterhead 4 to be fixed on prolongation knife bar 2.
Described cutterhead 4 is by upper and lower bipartition, and upper and lower two are fastened on prolongation knife bar 2 by bolt 8.
The effect of cutterhead 4 has not only acted as and has increased the purpose of cutting diameter and also add rigidity and the intensity of single-blade boring cutter 6.
Fig. 3 show machining state schematic diagram of the present invention.
In power head device installation process at the scene, the axis of unit head driving shaft can adjust and carry out the transmission of power by universal joint 3 with the axis tolerance of cutting axis, but to guarantee that the concordance of the axis and workpiece 7 machining benchmark axis that extend knife bar 2 i.e. can ensure that the axiality in whole two groups of holes.
If process three groups and the hole of above quantity simultaneously, increase centre frame 5, the quantity of cutterhead 4 quantity to hole, adjust universal joint 3, remain guarantee prolongation knife bar 2 axis consistent with workpiece 7 machining benchmark line, make to extend first group of hole of knife bar 2 axis in concrete operations consistent with central point line at last group hole and 7 machining benchmark lines, achieve interstitial hole and two ends centerline hole conllinear, simple to operate, thus the axiality in many groups hole coaxial after confirming processing.
Clamped one time of the present invention is fixed, can realize carrying out the hole more than two on an axis boring work, improve the machining accuracy of the several sets of apertures that on an axis, axiality had certain requirements, reduce production cost, save the duration, improve production efficiency and quality.
The embodiment above of the present invention, is merely illustrative, and is not only, and all changes within the scope of the present invention or in equivalent the scope of the present invention are all surrounded by the present invention.
