Abstract
The invention discloses a boring device for holes. The boring device for holes comprises a boring rod, cutter heads and a power head. The boring rod comprises a cuter rod and an extension cutter rod, the cutter rod and the extension cutter rod are connected through a universal joint, and the extension cutter rod is arranged on two central frames. The cutter heads are connected with single-blade boring cutters through fixing grooves, and the cutter heads are fixed to the extension cutter rod. The power head is connected with the cutter rod to achieve cutting and feeding actions. The cutter heads are formed by upper parts and lower parts, and the upper parts and the lower parts are connected and fixed to the extension cutter rod through bolts. According to the boring device for the holes, two or more sets of holes in one axial line can be bored through one time clamping and fixing, the machining precision of multiple sets of holes having certain requirements for coaxiality on the same axial line is improved, production cost is lowered, the working duration is shortened, and production efficiency and quality are improved.
Description
Technical field
The present invention relates to a kind of boring device, relate in particular to a kind of borer of hole, belong to Machining Technology field.
Background technology
In present metalworking field, there is the boring work in two groups of even many groups holes of requirement for axiality on same axis, because the amount of feeding of dynamic head main spindle is limited, so location and the clamping that need to carry out repeatedly during in the face of the larger two groups of holes of distance carry out boring, therefore the problem of bringing is exactly---in conversion blank position and again when clamping cutter, the positioning datum of blank can produce deviation in this process, will cause the axiality in two holes to produce deviation.
Summary of the invention
Technical problem to be solved by this invention is to carry out for not realizing clamped one time location to two groups of holes distant on same axis in prior art the not high defect of axiality that boring causes hole, and a kind of hole boring device is provided.
For solving this technical problem, the invention provides a kind of hole boring device, comprise boring bar, cutterhead and unit head, described boring bar comprises knife bar and prolongation knife bar, knife bar and prolongation knife bar connect by universal joint, extend knife bar and are arranged on two centre frames; On described cutterhead, be connected with single-blade boring cutter by holddown groove, cutterhead is fixed on and extends on knife bar; Shown in unit head be connected with knife bar realize cutting and feed motion.
Described cutterhead is by upper and lower bipartition, and upper and lower two are bolted to be fixed on and extend on knife bar.
Beneficial effect: clamped one time of the present invention is fixed, can realize boring work is carried out in the hole more than two on an axis, improve on an axis the have certain requirements machining accuracy in several groups of holes of axiality, reduce production cost, save the duration, improved production efficiency and quality.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the assembling schematic diagram of cutterhead of the present invention;
Fig. 3 is machining state schematic diagram of the present invention.
In figure: 1 knife bar, 2 extends knife bar, 3 universal joints, 4 cutterheads, 5 centre frames, 6 single-blade boring cutters, 7 workpiece, 8 bolts.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is specifically described.
Figure 1 shows that structural representation of the present invention.
The invention provides a kind of hole boring device, comprise boring bar, cutterhead and unit head.
Described boring bar comprises knife bar 1 and extends knife bar 2.
Shown in unit head be connected with knife bar 1, the effect of knife bar 1 is used for the cutting force of transferring power head, realizes cutting and feed motion.
Described knife bar 1 and prolongation knife bar 2 connect by universal joint 3, the effect of universal joint 3 can be trickle adjustment knife bar 1 and the angle that extends knife bar 2, not only ensure to extend knife bar 2 while cutting in the uniformity of datum axis, can also make it receive the cutting force that unit head is delivered to.
Extend knife bar 2 and be arranged on two centre frames 5, centre frame 5 is used for ensureing to extend stability and the degree of accuracy of knife bar 2.
Figure 2 shows that the assembling schematic diagram of cutterhead of the present invention.
On described cutterhead 4, be connected with single-blade boring cutter 6 by holddown groove, cutterhead 4 is fixed on and extends on knife bar 2.
Described cutterhead 4 is by upper and lower bipartition, and upper and lower two are fastened on and are extended on knife bar 2 by bolt 8.
The effect of cutterhead 4 has not only been played and has been increased the object of cutting diameter and also increased rigidity and the intensity of single-blade boring cutter 6.
Figure 3 shows that machining state schematic diagram of the present invention.
Power head device is at the scene in installation process, the transmission of power can be adjusted and be carried out by universal joint 3 to the axis tolerance of the axis of unit head driving shaft and cutting axis, but will guarantee to extend the axis of knife bar 2 and the uniformity of workpiece 7 machining benchmark axis can be guaranteed the axiality in whole two groups of holes.
If process the hole of three groups and above quantity simultaneously, increase centre frame 5, the cutterhead 4 quantity quantity to hole, adjust universal joint 3, remain and ensure that prolongation knife bar 2 axis are consistent with workpiece 7 machining benchmark lines, in concrete operations, make to extend first group of hole of knife bar 2 axis consistent with 7 machining benchmark lines with last group hole place central point line, realize interstitial hole and two ends centerline hole conllinear, simple to operate, thus confirm the axiality in coaxial many groups hole after processing.
Clamped one time of the present invention is fixed, can realize boring work is carried out in the hole more than two on an axis, improve on an axis the have certain requirements machining accuracy in several groups of holes of axiality, reduce production cost, save the duration, improved production efficiency and quality.
The above-mentioned embodiment of the present invention, just illustrates, and is not only, and change within the scope of the present invention all or that be equal in scope of the present invention is all surrounded by the present invention.
