Specific embodiment
The utility model provides a kind of turning molding machine for having ring rib shaft.Below in conjunction with attached drawing to the utility model
Technical solution is described in detail, so that it is more readily understood and grasps.
A kind of turning molding machine having ring rib shaft, as shown in Figure 1, including material axis feeding mechanism and turning molding machine
Structure, material axis 1 have spinning displacement and axial reciprocating displacement.
Material axis feeding mechanism belongs to the prior art, primarily serves rotation transformed material shaft 1 and the axial work for pushing or retracting material axis 1
With, be omitted in attached drawing material axis feeding mechanism diagram, as long as be able to achieve material axis 1 axial reciprocating and rotation.
As shown in figure 3, being the shaft idiosome schematic diagram of this case laptop rotating shaft comprising shaft main body, shaft main body axis
To including successively main shaft 2, spill annular groove 3, ring rib 4, inner shaft 5 and end two-stage chamfering 6, there are more forming parts, therefore
More demanding to the turning accuracy of turning molding machine, the truning fixture of general three stations or four stations is difficult to meet its molding
Demand, precision is lower after molding.
The turning shaping mechanism of this case is as depicted in figs. 1 and 2, including stand bite group 7 and axial bite group 8.
Wherein, stand bite group 7 includes cutting along the outer diameter turning portion 71 of material axis feeding mechanism feed direction setting, material axis
Cut portion 72, spill annular groove turning portion 73, inner shaft outer diameter turning portion 74 and ring rib periphery turning portion 75.And outer diameter turning portion 71,
Expect axis cutting part 72, spill annular groove turning portion 73, inner shaft outer diameter turning portion 74 and the cutting end in ring rib periphery turning portion 75 difference
Has the radial shift reciprocately towards the material axis.The benefit of such setting is the total processing stroke that can be reduced material axis 1, is prevented
Duplicating property shift reciprocately.
Axial bite group 8 includes end two-stage chamfering turning portion 81 and ring rib outer end facing portion 82, and end two-stage is fallen
The cutting end in angle turning portion 81 and ring rib outer end facing portion 82 has the axial reciprocating displacement towards material axis 1 respectively.
The specific turning process and principle of this case turning molding machine are illustrated, are stand bite group 7 first, outside
Diameter turning portion 71 carries out the outer diameter turning to main shaft 2, and certainly, which acts on whole bearing, when outer diameter turning
After carry out 5 outer diameter of inner shaft molding, by inner shaft outer diameter turning portion 74 carry out radial displacement, material axis 1 be axially moved simultaneously rotates,
5 outer diameter turning of inner shaft finishes, and then carries out the machine-shaping of spill annular groove 3, it should be noted that spill annular groove turning portion 73
Cutting end section is in triangular shape, can form the two sides conical surface of spill annular groove 3, after spill annular groove 3 forms, followed by ring rib
Periphery turning portion 75 carries out refine to the outer peripheral surface of ring rib 4, it is ensured that the precision of shaft.
Operation is carried out followed by axial bite group 8, the cutting end by ring rib outer end facing portion 82 is axially extended, real
Now to the refine of 4 outer end face of ring rib, the cutting end by end two-stage chamfering turning portion 81 is axially extended, realizes to two-stage chamfering
6 molding.
It is finally the operation for expecting axis cutting part 72 in stand bite group 7, separation is cut to the shaft embryo of forming.
It should be noted that preventing the presence of vehicle from each other between each station in order to ensure the requirements for high precision of shaft
Influence is cut, any turning portion and cutting part are all isolated operations.
As shown in Fig. 2, being illustrated to the setting distribution of stand bite group 7 and axial bite group 8:
The axis projection in spill annular groove turning portion 73, inner shaft outer diameter turning portion 74 and ring rib periphery turning portion 75 is in around material
The fan-shaped region 9 of axis is distributed.It is designed in this way the influence that turning portion can be prevented mutual, reduces the turning stroke of shaft, is saved
The installation space in turning portion is saved.
In addition, the axis projection in outer diameter turning portion 71 is located in fan-shaped region 9.The axis projection of material axis cutting part 72 is located at
In fan-shaped region 9.Preferentially, the axis projection in outer diameter turning portion 71 and the axis projection in spill annular groove turning portion 73 overlap.
The design for so optimizing entire station, reduces the linear route of material axis 1, and reduces the space of whole equipment.
In optimum embodiment, between the turning end in spill annular groove turning portion 73 and the turning end in inner shaft outer diameter turning portion 74
Axial distance is greater than the peripheral, axial size of ring rib 4.
Specifically describe, the shaft idiosome after outer diameter turning first carry out inner shaft 5 outer diameter processing, when shaft plumular axis to
After being moved to 5 outer diameter completion of processing of inner shaft, the inner shaft outer diameter turning portion 74 that directly bounces back, stretching spill annular groove turning portion 73 can connect
Continuous property carries out the turning of spill annular groove 3, increases the continuity between turning station, improves turning efficiency.
