Description
Technical field
The present invention relates to mining reducer technology field more particularly to a kind of gear shaft roll flute toolings and assembly method.
Background technique
Coalcutter sun gear and speed reducer sun gear, it is toothed member that structure is identical, alternatively referred to as gear shaft, wherein adopting
Coal machine sun gear and JS series reduction sun gear are the gear shaft that axial length is less than 280mm.When gear shaft axial length is less than 280mm
When, such gear shaft is when carrying out roll flute processing using conventional roll flute processing method, due to the limitation of grinding wheel size, Wu Fabao
Demonstrate,prove grinding wheel smooth withdrawing after roll flute.
Fig. 5 is the assembling schematic diagram of the conventional roll flute processing method of the prior art.As shown in figure 5, gear shaft 1 to be processed is logical
It crosses radial clamping tooling 5 and is fixed on 3 top of workbench, wherein radial clamping tooling 5 includes top, square pillar, pedestal and diameter
To clamping clamping plate, processing gear shaft 1 is treated by grinding wheel 4 and carries out roll flute processing, due to the size of grinding wheel 4 and gear shaft to be processed 1
It influences, treats processing gear shaft 1 in grinding wheel 4 and carry out in roll flute process, may cause grinding wheel 4 and radial clamping device 5 is sent out
Raw interference, so as to cause the damage of radially loading clip tool 5 and grinding wheel 4.Therefore, it is small not to be suitable for axial length for conventional roll flute processing method
In the roll flute processing of the gear shaft of 280mm.In order to overcome gear shaft to lead to not carry out asking for roll flute processing since axial length is shorter
Topic, the prior art process secondary segment using the technique for increasing a length of 50mm-70mm in gear shaft spline one end to realize such tooth
The roll flute of wheel shaft is processed.
Fig. 6 is that the technique of the prior art lengthens the assembling schematic diagram of roll flute processing method.As shown in fig. 6, work gear to be added
The technique that spline one end of axis 1 increases by a Duan Changwei 50mm-70mm processes secondary segment 101, passes through work using radial clamping device 5
Skill processes secondary segment 101 and gear shaft 1 to be processed is fixed on the top of workbench 3, at this time by grinding wheel 4 treat processing gear shaft 1 into
When row roll flute is processed, grinding wheel 4 will not interfere with radial clamping device 5.After gear shaft 1 to be processed completes all roll flute processes,
Technique processing secondary segment 101 is cut off again.Thus it will lead to material cost and increase by 15%~20%, and due to the increase of process,
Production efficiency is caused to reduce.In addition, when carrying out the damage of the gear shaft after roll flute processing using the roll flute processing method need to repair,
Since the technique processing secondary segment for stationary positioned has been removed, the stationary positioned benchmark of the gear shaft changes, may
Repositioning position is caused deviation occur.
Therefore, the roll flute processing for how realizing gear shaft of the axial length less than 280mm, guarantees the positioning of gear shaft processing front and back
Benchmark is consistent, while reducing cost and improving production efficiency, becomes those skilled in the art's technical problem urgently to be resolved.
