Height typically uses lathe turning to process, and machined surface is more, time-consuming, can only process 30-50 parts within one day, production efficiency is low.
Consideration is used broaching machine instead and is processed, but present broaching tool structure design is unreasonable, is mismatched with the endoporus of free bearing copper sheathing.
Invention content
The purpose of this utility model is to provide a kind of broaching tool axis.
The utility model will solve that existing free bearing copper sheathing part process is cumbersome, not matching processing dress
It sets, the problem of low production efficiency.
The technical solution of the utility model is:A kind of broaching tool axis, including spindle nose, axis tail and blade region, the broaching tool axis
Blade region parallel show blade, the structure of each blade is identical, and the blade for being located at left side is less than right side adjacent thereto
Blade；The cross section of the blade includes four, upper and lower, left and right side, and upper side edge is mutually parallel with lower side, left side
Side is mutually parallel with right edge, and the upper side edge is mutually perpendicular to the left side, right edge；The left and right ends of upper side edge
It is in arc transition between the upper end of the left side, the upper end of right edge；The left and right ends of lower side and the left side
It is in arc transition between the lower end on side, the lower end of right edge；The spindle nose is equipped with fixing groove.
Preferably, the blade region is in integrally incline structure left small and right large.
Preferably, the side of the blade is equipped with insert groove.
The beneficial effects of the utility model are：The utility model is installed in special broaching machine, and fixed form is solid and reliable, and
It is convenient for disassembly and assembly；Broaching tool axis it is reasonable in design, broaching tool axis, which from left to right moves, can once complete to free bearing copper sleeve inner hole
Processing, when broaching tool axis falls back on right from a left side, moreover it is possible to take the workpiece processed out of.The labor intensity for reducing worker, improves life
Produce efficiency.

Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
As shown, the utility model includes spindle nose 23, axis tail 24 and blade region 13, the blade region of the broaching tool axis 4
13 parallels show blade 12, and the structure of each blade 12 is identical, and the blade 12 for being located at left side is less than right side adjacent thereto
Blade 12；The cross section of the blade 12 includes four, upper and lower, left and right side, and upper side edge 20 and lower side 22 are mutually flat
Row, left side 19 are mutually parallel with right edge 21, and the upper side edge 20 mutually hangs down with the left side 19, right edge 21
Directly；The left and right ends of upper side edge 20 and the upper end of the left side 19, right edge 21 upper end between be in arc transition；Downside
The left and right ends on side 22 and the lower end of the left side 19, right edge 21 lower end between be in arc transition；The spindle nose
23 are equipped with fixing groove 10.
In the present embodiment, the whole blade region 13 is in incline structure left small and right large.
In the present embodiment, the side of the blade 12 is equipped with insert groove 11, and insert groove 11 is cut for being discharged.
Fixation principle：It is connected by broaching tool shaft fixing device 3 between broaching tool axis 4 and the Mobile base 2 of broaching machine 1, includes mainly
The upper surface of shaft end fixed seat 8 and fixed plug assembly 9, the shaft end fixed seat 8 is equipped with inserting groove 14, and the shaft end is solid
Hole is stretched into the right side of reservation 8 equipped with broaching tool axis, and the fixation plug assembly 9 includes insert-connecting plate 17, handle 15 and connection rod
16, the lower end of the insert-connecting plate 17 is equipped with the interface 18 of the arc-shaped of indent；The spindle nose 23 of the broaching tool axis 4 stretches into drawing
Cutter shaft stretches into hole, and withstands on the Mobile base 2, and the fixation plug assembly 9 is from the inserting groove in shaft end fixed seat 8
It is stretched into 14, thus the interface 18 is straddled to be fixed in the fixing groove 10 of broaching tool axis 4, the fixed structure is solid and reliable.
Operation principle：In use, being positioned over free bearing copper sheathing workpiece 7 at the broaching tool axis access hole 5 of 1 right end of broaching machine
In clamping workpiece device 6, broaching tool axis 4 is then passed through into free bearing copper sheathing workpiece 7, is installed to the Mobile base 2 of broaching machine 1, liquid is started
Cylinder pressure is processed free bearing copper sheathing workpiece 7, by broaching tool axis 4 from right toward Zola when broaching tool axis 4 moves left end to, due to broaching tool
The whole blade region 13 of axis 4 is in incline structure left small and right large, is thus gradually gradually expanded to 7 endoporus of free bearing copper sheathing workpiece, most
Eventually to 7 completion of processing of free bearing copper sheathing workpiece.When broaching tool axis 4 is retracted to the right, due to axis tail and the free bearing copper sheathing workpiece 7 of broaching tool axis 4
Between have frictional force, free bearing copper sheathing workpiece 7 is taken out of out of clamping workpiece device 6, removes free bearing copper sheathing workpiece 7, then unloads
Broaching tool axis 4 is the interior hole machined for completing a free bearing copper sheathing workpiece 7.
