A kind of aluminum wheel of truck inclined hole chamfering lathe
Technical field
The present invention relates to a kind of lathe, especially a kind of abnormal curved surface pressure head and inside and outside chamfering one-time formed wheel of truck inclined hole chamfering lathe.
Background technology
When carrying out chamfer machining to the inside and outside seamed edge of the inclined hole on wheel, because these pore size distributions are on workpiece axial end or the cydariform surfaces of revolution, the inclined hole angled with axis of workpiece.The inside and outside seamed edge in hole is all space curve, is the intersection that a cydariform surfaces of revolution becomes certain angle intersecting shape to become with a cylinder.It is carry out chamfer machining to the seamed edge of inclined hole like this that completing of task completes, external integrated mill uses large-scale Five-axis NC Machining Center, and equipment investment is comparatively large, and process time is longer, be have machining, high lathe price bears difficulty to medium-sized and small enterprises.
Summary of the invention
In order to solve the problem, the invention provides equipment investment little, with low cost, and the wheel inclined hole chamfering special purpose machine tool that process time is short.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is a kind of aluminum wheel of truck inclined hole chamfering lathe, comprise lathe bed, lathe bed is provided with angle back-up block, one workpiece is placed on angle back-up block and is located by product center hole locating flange, angle back-up block is also provided with the circumferential alignment pin of positioning workpieces angle, lathe bed lower end is provided with lower chamfering extrusion head, and in the upper end of lathe bed, corresponding with lower chamfering extrusion head be provided with chamfering extrusion head, upper chamfering extrusion head is driven by hydraulic cylinder and moves up and down.
Further improvement of the present invention is: upper chamfering extrusion head and lower chamfering extrusion head are special-shaped space curved surface pressure head.
Further improvement of the present invention is: the angle of inclination of workpiece is 15-25 degree.
The invention has the beneficial effects as follows: the present invention adopts abnormal curved surface pressure head
,the Integration ofTechnology such as extrusion process, hydraulic pressure, PLC, achieve the inside and outside lead angle time processing to aluminum wheel of truck 10 inclined holes, every technology, efficiency index reach Five-axis NC Machining Center level, and the cost dropped into is much lower, reduce the fund input of enterprise, reduce risk, concrete function: 1) workpiece centering; 2) abnormal curved surface face pressure head is inside and outside extrudes chamfering simultaneously; 3) equation graduation; 4) the position radius in hole can adjust in heart R200-R280 interval within the workpiece; 5) workpiece angle of inclination can from 15 °-25 ° interval adjustment; 6) PLC programming automatic cycle.
Novel structure of the present invention, easy to operate, abnormal curved surface pressure head one-step pore-creating, completes complicated work with less input, avoids high price to purchase the investment risk of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1-lathe bed, 2-angle back-up block, 3-workpiece, 4-circumference alignment pin, chamfering extrusion head under 5-, the upper chamfering extrusion head of 6-, 7-hydraulic cylinder, 8-product center hole locating flange.
Detailed description of the invention
In order to deepen the understanding of the present invention, be described in further detail the present invention below in conjunction with drawings and Examples, this embodiment, only for explaining the present invention, does not hook old restriction to protection scope of the present invention.
As shown in Figure 1, the present invention is a kind of aluminum wheel of truck inclined hole chamfering lathe, comprise lathe bed 1, described lathe bed 1 is provided with angle back-up block 2, one workpiece 3 is placed on described angle back-up block 2 and is located by product center hole locating flange 8, described angle back-up block 2 is also provided with the circumferential alignment pin 4 of locating described workpiece 3 angle, the angle of inclination of described workpiece 3 is 15-25 degree, the change at the angle of inclination of workpiece is realized by the adjustment of alignment pin, described lathe bed 1 lower end is provided with lower chamfering extrusion head 5, in the upper end of described lathe bed 1, corresponding with described lower chamfering extrusion head 5 is provided with upper chamfering extrusion head 6, described upper chamfering extrusion head 6 is driven by hydraulic cylinder 7 and moves up and down, described upper chamfering extrusion head 5 and described lower chamfering extrusion head 6 are special-shaped space curved surface pressure head, in the formation of two abnormal curved surface pressure head lands is, what formation whipped mutually by the outer cydariform surfaces of revolution and a cylinder (becoming certain angle) whips on line mutually, intersect with the parallax of 60 ° again, complete the curved surface of circumference envelope.
The present invention adopts abnormal curved surface pressure head
,the Integration ofTechnology such as extrusion process, hydraulic pressure, PLC, achieve the inside and outside lead angle time processing to aluminum wheel of truck 10, every technology, efficiency index reach Five-axis NC Machining Center level, and the cost dropped into is much lower, reduce the fund input of enterprise, reduce risk, concrete function: 1) workpiece centering; 2) abnormal curved surface face pressure head is inside and outside extrudes chamfering simultaneously; 3) equation graduation; 4) the position radius in hole can adjust in heart R200-R280 interval within the workpiece; 5) workpiece angle of inclination can from 15 °-25 ° interval adjustment; 6) PLC programming automatic cycle.
Novel structure of the present invention, easy to operate, abnormal curved surface pressure head one-step pore-creating, completes complicated work with less input, avoids high price to purchase the investment risk of product.
