Description

A kind of hole boring device

Technical field

The utility model relates to a kind of boring device, relates in particular to a kind of borer of hole, belongs 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 in the utility model 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 utility model provides a kind of hole boring device, comprises boring bar, cutterhead and unit head, and described boring bar comprises knife bar and prolongation knife bar, and 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: the utility model clamped one time 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.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is specifically described.

Figure 1 shows that structural representation of the present utility model.

The utility model provides a kind of hole boring device, comprises 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 the utility model cutterhead.

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 the utility model machining state schematic diagram.

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.

The utility model clamped one time 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 utility model, just illustrates, and is not only, all within the scope of the utility model or the change being equal in scope of the present utility model all surrounded by the utility model.
