Embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 8, the invention provides a kind of broaching machine frock, the broaching machine frock is used for
Fixed workpiece 40, workpiece 40 is circumferential to be evenly distributed with processing hole 41, and the center of workpiece 40 has through hole 42, and the broaching machine frock includes
The tool base plate 10 of broaching machine side is fixed on, is fixedly connected between tool base plate 10 and broaching machine by bottom plate clamping screw 11, work
The bottom plate centring ring 12 of plate face is provided through on dress bottom plate 10, side of the tool base plate away from broaching machine is provided with auxiliary work-piece 40
The fast aligning system of the rotation of Constrained workpiece 40 is set in the rotating shaft system 30 of rotation, tool base plate 10.In use, by rotating shaft
System 30 realizes the positioning of workpiece 40, rotational workpieces 40, by fast aligning system restriction workpiece through the through hole 42 on workpiece 40
40 will stop the rotation, so that the processing hole 41 of workpiece 40 quickly is adjusted into the position coaxial with bottom plate centring ring 12, this is quick
The effect of centering system is that auxiliary work-piece is stopped the rotation in the position for being adapted to broaching tool operation, thus can be used of the prior art
Any spin-ended device, it is to avoid workpiece adjusts the problem of anglec of rotation is to be directed at the broaching machine alignment of shafts repeatedly.
Further, as shown in fig. 7, above-mentioned rotating shaft system 30 includes mandrel 31, mandrel 31 passes through mandrel clamping screw 32
It is fixedly connected in tool base plate 10, spring washer 33, the outside of mandrel 31 is provided between mandrel clamping screw 32 and mandrel 31
Two taper roll bearings 34 are symmetrically arranged with, the outer ring of taper roll bearing 34 is cased with mandrel outer ring 35, away from tool base plate 10
The outside of taper roll bearing 34 be provided with end ring 36, mandrel 31 and be threaded with constraint taper roll bearing 34 and axle
Hold the bearing lock nut 37 of back-up ring 36.Further, the end of mandrel 31 has stepped circular protrusions, while at frock bottom
Relevant position on plate 10 sets counterbore, and mandrel 31 assembles fixed by the counterbore in stepped circular protrusions and tool base plate 10
Position.The present solution provides a kind of rotating shaft system of concrete structure, workpiece 40 is enclosed on bearing outside 35 when using, due to circle
The presence of taper roller bearing 34, workpiece 40 can rotate around mandrel 31 together with bearing outside 35.
Further, as shown in figure 9, side of the mandrel 31 away from tool base plate 10 sets the transverse shifting of Constrained workpiece 40
Baffle plate 38, baffle plate 38 is threadedly coupled with mandrel 31 by baffle plate fixing nut 39, when workpiece 40 is enclosed on bearing outside 35 it

Constraint, workpiece 40 is limited between baffle plate 38 and tool base plate 10, it is ensured that axial shifting does not occur during broaching for workpiece 40
It is dynamic.
Further, as shown in fig. 6, heavier in order to solve workpiece and frock of the present invention itself, simple use bottom plate is locked
The problem of fastness of bolt 11 is not good enough, can be symmetrical arranged two or more Auxiliary supports in the lower surface of tool base plate 10
Leg 20, the Auxiliary support leg 20 is threadedly coupled with tool base plate 10；And it is possible in Auxiliary support leg 20 away from tool base plate
10 one end sets supporting leg regulating bolt 21, and supporting leg regulating bolt 21 is threadedly coupled with Auxiliary support leg 20, Auxiliary support
Leg 20 can be used in conjunction with each other with supporting leg regulating bolt 21, while the supporting role to tool base plate is realized, may be used also
The vibrations produced with reducing in machining process.
In the above-described embodiments, as shown in Figure 10, the top of workpiece 40 exceeds the upper surface of tool base plate 10, fast aligning system
Including latch 50, processing hole 41 of the latch 50 through the close upper surface of tool base plate 10 on workpiece 40.The lower section of latch 50 is provided with
Constraint workpiece 40 rotate axle system 30 rotation stop loose piece 60, the present solution provides a kind of easy fast aligning system
System, using the characteristics of hole 41 is circumferential to be uniformly distributed is processed on workpiece 40, stop loose piece 60 is placed in the upper surface of tool base plate 10, by
Centre-to-centre spacing in the processing hole 41 of different workpieces 40 is different, thus needs stopping for the different prefabricated different-thickness of workpiece 40
Dynamic loose piece 60, when workpiece 40 rotates, latch 50 can be constrained by stop loose piece 60 and then limit workpiece 40 and rotated, now workpiece
Fast aligning function is realized in processing hole 41 to be processed by quick alignment to the center of bottom plate centring ring 12 on 40, when broaching tool is passed through
Processing hole 41 to be processed and after installing, i.e., pull out latch 50, broaching tool leading portion is come with guiding, broaching tool running
Leading portion be oriented to can automatic fine tuning workpiece with ensure processing the axle center of hole 41 be directed at broaching machine spindle axis completely, when the processing hole 41 is processed
After the completion of, in another processing hole 41 that the upper surface of tool base plate 10 is reinserted after latch 50 is extracted, repeat above-mentioned workpiece rotation
Turn, fast aligning is operated, until workpiece 40 is machined.
Further, as shown in figure 11, the upper surface of tool base plate 10 has T-shaped groove 13, and stop loose piece 60 includes having T
The sliding block 70 of shape convex portion 71, T-shaped convex portion 71 is mutually adapted with T-shaped groove 13, and height cushion block 72, sliding block 70 are provided with sliding block 70
