Abstract
The utility model discloses a cam bearing hole boring device which comprises a machine tool spindle and a boring bar arranged on a boring cutter, wherein the machine tool spindle is provided with a power output end, and the tail end of the boring bar and the power output end of the machine tool spindle are connected by a cross-shaped shaft type universal coupler. The cross-shaped shaft type universal coupler is adopted as a coupler betweenthe boring bar and the machine tool spindle, the torsion can be transferred by utilizing the large coaxiality error tolerance characteristic of the cross-shaped shaft type universal coupler even under the condition that the machine tool spindle and the boring bar are not entirely coaxial, and the errors caused by measuring correction can be eliminated in rotating of the spindle. Therefore, various form and location tolerances of the cam bearing holes can be guaranteed in production, and the durability of devices, such as the boring bar and a boring bar supporting assembly can be guaranteed. The cam bearing hole boring device can be widely used for machining work of boring the cam bearing holes.
Description
Technical field
The utility model relates to a kind of camshaft bearing hole boring device in the machined field.
Background technology
In the bore hole operation in the camshaft bearing hole of large-scale body, adopt the rigidly connected connected mode of boring bar and machine tool chief axis often, namely one of boring bar extend in the hole to be processed, and the other end is connected with machine tool chief axis by a simple shaft joint.But this structure makes machine tool chief axis and boring bar with the axial adjustment difficulty, and the boring bar rotary oscillation is bigger when causing work, and the copper sheathing wearing and tearing of boring bar holder are very fast.Gap between last boring bar and the boring bar holder becomes big, and the axiality that occurs egg type or each grade hole when causing fine finishining camshaft bearing hole is overproof.
Universal coupling with spider is a kind of shaft coupling relatively more commonly used.It is big or move axially bigger diaxon isogonism speed revolution continuously at same axis or axis knuckle to utilize the characteristics of its structure can make not, and transmitting torque and motion reliably.So the functional characteristic of this universal coupling with spider can should use in the boring device of camshaft bearing hole.
The utility model content
The technical problems to be solved in the utility model is: a kind of camshaft bearing hole boring device is provided, it can make when having bigger coaxiality error between boring bar axle and the machine tool chief axis, boring camshaft bearing hole well still, the various form and position tolerances in hole when guaranteeing the machining cam dead eye.
The solution that the utility model solves its technical problem is:
A kind of camshaft bearing hole boring device, comprise machine tool chief axis and on establish the boring bar of boring cutter, machine tool chief axis has clutch end, the end of described boring bar connects by universal coupling with spider with the clutch end of machine tool chief axis.
As further improvement in the technical proposal, the clutch end of described machine tool chief axis comprises and the coaxial handle of a knife that connects of machine tool chief axis, one of universal coupling with spider connects with the end of boring bar, and other end and handle of a knife are linked together by a transition adpting flange.
As further improvement in the technical proposal, a plurality of boring cutters are arranged at interval along the shaft of boring bar.
The beneficial effects of the utility model are: the utility model has adopted universal coupling with spider as the shaft coupling between boring bar and the machine tool chief axis, utilize the big characteristics of universal coupling with spider coaxiality error tolerance, even if make that machine tool chief axis is not exclusively coaxial with boring bar, also can allow torsion obtain transmitting, can eliminate during main axis rotation because the error that measurement update causes.Therefore, the various form and position tolerances in hole can be guaranteed during the machining cam dead eye, and have guaranteed the durability of devices such as boring bar and boring bar holder.The utility model can be widely used in the machined in boring camshaft bearing hole.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done simple declaration in will describing embodiment below.Obviously, described accompanying drawing is a part of embodiment of the present utility model, rather than whole embodiment, and those skilled in the art can also obtain other designs and accompanying drawing according to these accompanying drawings under the prerequisite of not paying creative work.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, feature and effect fully.Obviously; described embodiment is a part of embodiment of the present utility model, rather than whole embodiment, based on embodiment of the present utility model; other embodiment that those skilled in the art obtains under the prerequisite of not paying creative work all belong to the scope that the utility model is protected.In addition, all connection/annexations of mentioning in the literary composition are not to refer to that singly member directly joins, and refer to and can connect auxiliary by adding or reducing according to concrete performance, form more excellent draw bail.
With reference to Fig. 1, a kind of camshaft bearing hole boring device, comprise machine tool chief axis 9 and on establish the boring bar 3 of boring cutter 7, machine tool chief axis 9 has clutch end, the end of described boring bar 3 connects by universal coupling with spider 4 with the clutch end of machine tool chief axis 9.The model of universal coupling with spider 4 is SWC100-WD.
Be further used as preferred embodiment, the clutch end of described machine tool chief axis 9 comprises and the machine tool chief axis 9 coaxial handle of a knifes that connect 6,4 one ends with boring bar 3 of universal coupling with spider connect, and other end and handle of a knife 6 are linked together by a transition adpting flange 5.
For convenience simultaneously boring is carried out in a plurality of dead eyes position in the body, can make a plurality of boring cutters 7 arrange at interval along the shaft of boring bar 3, the boring cutter more than 8 for example is installed.
The processing technology of holding the hole with diesel engine casing inner camshaft shown in Figure 1 is that example illustrates function of the present utility model.The bearing block 2 that is provided with support plate 1 and connects with support plate 1 in casing, bearing block 2 middle perforates also are nested with copper sheathing 8.Be one group of boring bar holder assembly with support plate 1, bearing block 2, copper sheathing 8, be provided with the such boring bar holder assemblies of many covers in the axial direction.Boring bar 3 passes copper sheathing 8 and supports as head end with this, and the end of boring bar 3 connects with the output of universal coupling with spider 4, after the input of universal coupling with spider 4 connects transition adpting flange 5, connects with handle of a knife 6.In advance, boring bar 3 is consistent with machine tool chief axis 9 furnishing axialities as far as possible, guarantees the good position precision as far as possible.When machine tool chief axis 9 rotates, can drive boring bar 3 related boring cutters 7 and rotate boring camshaft bearing hole.Because the error of universal coupling with spider 4 tolerance characteristic, even there is error in prior measurement update, also machining hole correctly, guarantee the form and position tolerance in hole, and the amplitude of fluctuation of boring bar 3 has been greatly diminished, and the frictional impact between the copper sheathing 8 also just correspondingly reduces, and has prolonged the life-span of boring bar holder assembly.
More than preferred embodiments of the present utility model is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite of the utility model spirit, the modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
