On serves large end face in heart hole；Transverse slat is fixedly installed in the top of multiple columns, and guide sleeves are fixedly installed on the transverse slat, draw
Key teeth is equipped with guide sleeve centre bore, and the key teeth tooth form direction in positioning center hole, guide sleeves centre bore is consistent.
Bushing is set between the guide plate and guide finger.
Stop pin is additionally provided with the locating piece, bottom and the guide finger of the stop pin form one, and guiding is left on top
One distance of pin.
The utility model combination serves structure, using serves small end is cylindrical and end face positioning, rhombus pin orientation,
Cutting force makes serves not have the possibility of any offset and play during broaching, solves in the same direction and with board clamping is oriented to
The problem on deformation of workpiece in processing.The utility model device is fixed in horizontal broaching machine terminal pad, and is determined using chassis shoulder
The heart, ensures that device center and broaching machine center overlap.Installation fixed design of the guide finger of the utility model device in locating piece
There is stop pin, bushing is designed with guide plate, make the guiding of guide plate, compress reliably, reprocess conveniently.The utility model profit at the same time
With more column connecting base plates and transverse slat, device rigidity, the deformation of anti-locking apparatus at work are improved.Broaching tool is designed with transverse slat
Guide sleeves, while locating piece guides broaching tool front end, and broaching tool axis, serves axis overlap, in the course of work not
Deflection is had, improves broaching tool service life.The serves bearing capacity of the utility model device broaching is strong, to neutral, guiding
Property it is good, the wheel shaft, wheel hub strength reduction to undercarriage are small, to improve undercarriage service life it is significant.The utility model
Device is applied in the wire pulling method of multiple model internal splines.
