Specific embodiment
In order to make technological means of the utility model, creation characteristic, reach purpose and effect is more clear and is easy to
Understand, the utility model be further elaborated with reference to the accompanying drawings and detailed description:
As described in Fig. 1-8, a kind of Flywheel disc inner hole key slot broaching machine, including broaching tool bar 2 and pulling broaching tool bar 2 are done along its axis
The power device 1 moved in a straight line, the centre for being fixed on broaching machine side are equipped with the positioning disk 3 of through-hole, and the broaching tool bar 2 includes
Telescopic segment 22 and broaching tool section 21, broaching tool section 21 pass through the through-hole and stretch out outside lathe, and the broaching tool 5 is along 2 length direction of broaching tool bar
It is arranged in broaching tool section 21, the telescopic segment 22 cooperates with the through-hole and 22 cross section of the telescopic segment is greater than broaching tool section 21
Cross section, the broaching tool bar 2 may pass through 4 inner hole 41 of Flywheel disc, and that Flywheel disc 4 can be inserted in from broaching tool bar 2 is pre- to positioning disk 3
Positioning is set, the position of 41 keyway 42 of inner hole after 5 face of the broaching tool positioning.The cross section of inner hole 41 is greater than the section of pull rod section,
In addition broaching tool 5, Flywheel disc 4 still can be inserted in from 2 end of broaching tool bar, to keep the intensity of broaching tool bar 2 big as far as possible, telescopic segment 22
Diameter is identical as the diameter of inner hole 41 but keeps certain clearance fit, and the section of the broaching tool section 21 includes two sections facing each other
Circular arc, wherein one section of circular arc pair the side of broaching tool section 21 be overlapped with the elongated surfaces on the cylindrical surface of the telescopic segment 22, draw
Knife 5 is set to the middle of this section, another section of circular arc pair broaching tool section 21 side when the broaching tool bar 2 passes through inner hole 41
Cooperate with 41 inner wall of inner hole.That is radius corresponding to two sections of arcs is identical as internal diameter, the spacing between two sections of circular arcs and broaching tool 5
It is highly roughly the same, so that the section of broaching tool section 21 is as big as possible, and then obtains biggish bending strength, it is convenient for kerve.Institute
21 length of broaching tool section is stated greater than broaching tool 5, the linear distance of the broaching tool 5 and 22 end face of telescopic segment is formed greater than 4 thickness of Flywheel disc
The changeover portion 23 that Flywheel disc 4 is inserted in.Both it had been not provided with the thickness that 5 end of broaching tool is greater than Flywheel disc 4 to the linear distance of telescopic segment 22
Degree, is conveniently inserted in.
The positioning disk 3 is equipped with the positioning column 32 with 43 cooperation lateral opening on Flywheel disc 4, and limits Flywheel disc from side
4 block 31, to limit the moving horizontally on positioning disk 3 of Flywheel disc 4.32 upper end of positioning column is arc-shaped, and facilitates guiding.?
When kerve, broaching tool bar 2 gives the power in Flywheel disc 4 radial power and pull direction, it is therefore desirable to which positioning disk 3 gives the two
The limitation in direction.The utility model is given and is limited using lateral opening 43 and inside and outside contour of Flywheel disc 4 itself.It is clearly aobvious in Fig. 2
Show work relationship, does not provide baffle arrangement.
5 cutter head 51 of broaching tool is in half-cone, and bottom connects with broaching tool bar 2.Facilitate fluting, nail is separate, reduces broaching tool 5
With the impulsive contact force between Flywheel disc 4, prevent broaching tool 5 from deforming.The side and upper surface of second half section when the work of the broaching tool 5
Equipped with several grooves 52.During kerve, the inner wall of slot has certain surface stress, can deform after pulling, cause slot
Section become smaller, which can make slot in groove 52 by being deformation, and then further part chip deflection is greatly reduced and drawn
Deformation after slot.
Entire kerve process, carries out in the environment of oil immersion, therefore atomizer 6 is equipped with above the positioning disk 3, positioning
Oil-containing groove 7 is equipped with below disk 3, so as to oil spout and recycling.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
