Description

[Detailed description of the invention] The invention can be used in a gear chamfering machine that chamfers the top end face of the teeth of various gears such as hypoid gears and spiral bevel gears. This invention relates to a setting gauge capable of reproducing or indicating the optimum setting position of a machine.

Conventionally, as shown in FIG. 1, on a chamfering machine main body 1, a swing arm 3 supported by a shaft 2 so as to be able to swing back and forth in the horizontal direction has tool rests 4 and 5 for chamfering outer and inner ends, respectively.
supports the outer and inner end chamfering cutters 6 and 7, and as shown in FIG. The gear 12 to be chamfered can be chamfered by supporting the pin 11 for chamfering, lowering the pin 11, and adjusting the rotation of the gear 12 so that it fits between the adjacent tooth surfaces of the gear 12 and fits with the pin 11. is finally positioned to chuck the shaft of gear 12, and the swinging of swing arm 3 and gear 1
A gear chamfering machine that performs chamfering by synchronizing two intermittent rotations is well known.

By the way, in this type of chamfering machine, each of the blades 6, 7, . The position adjustment of each tool rest 4, 5 and the positioning pin 11 using the mounting base 10 is done individually, and it takes a lot of time and skill to complete the set properly, and it is difficult to process another gear. If you change to
Due to the change in the mounting position of the blade 6゜7, the positioning pin 1
There was a problem in that the position of 1 had to be changed and the setting had to be done again from -.

The present invention has been made in view of such conventional problems, and provides a new setting gauge for gear chamfering, and by using the gauge, it is easy to set many types of gears on a chamfering machine. And it can be done accurately.

Hereinafter, the present invention will be specifically explained with reference to the illustrated embodiments.

As shown in Fig. 3, setting gauge 2 according to the present invention

Both ends of a screw shaft 330 that is screwed into the screw hole 32 of the Y-axis slide member 24 provided in the direction are supported by a pair of rising walls 23c and 23d, respectively, and the Y-axis slide member 24 is moved in the Y-axis direction by operating the knob 34. move it.

The Y-axis slide member 24 is fixed after adjustment by a set screw 35 provided to the Y-axis threaded shaft 33, as shown in FIG.

Further, as shown in FIGS. 3 and 4, the X-axis slide member 25 is located at the intersection of the center line of the X-axis screw shaft 28 and the center line of the Y-axis screw shaft 33 (actually, the center line The positioning pin 11 (FIG. 2,
The upper plate part 25a is provided with a tapered reference hole 36 that is compatible with the upper plate part 25a (see figure), and the upper plate part 25a is bent downward from the end in the X-axis direction, and the vertical guide hole 2 is provided in the Y-axis slide member 24.
4a in the vertical direction, that is, in the Z-axis direction.
A vertical part 25b provided with an axial scale is bent horizontally from its lower end in the opposite direction to the upper plate part 25a, and a head 37a is embedded in the end of the Y-axis slide member 24 in the X-axis direction. It consists of a horizontal part 25c provided with a screw hole 38 to be screwed into the Z-axis direction screw shaft 37 which is supported downward in the vertical position.By rotating the head 37a of the screw shaft 370 with an appropriate tool, The slide member 25 can be displaced in two axial directions.

In FIG. 4, reference numeral 39 is a receiving nut for the Z-axis direction threaded shaft 37, and the two-axis sliding member 25 is fixed by this receiving nut 39 on the horizontal portion 2 of the two-axis sliding member 25.
5c from below and support it, and the vertical part 2
This is done by pressing the fixing screw 40 provided on the Y-axis slide member 24 against the Y-axis slide member 5b from the horizontal direction.

In addition, in FIG. 3, 42 is a positioning rod in the Z-axis direction that is supported by a bracket 43 at a fixed position forward in the Y-axis direction from the tip of the extension part 22b that extends the support body 22 in the X-axis direction -M. , as described later, this positioning rod 4
2 is a setting gauge 20 for the swing arm
Common tool rest for positioning button and swing arm (
(see Figure 6).

Next, a method of using the setting gauge 20 having the above structure will be explained.

(I) Preliminary Measurement First, turn on the chamfering machine described in FIGS. 1 and 2, and finally determine the optimal set state of the gear 12 to be chamfered based on the position of the positioning pin 11 at that time. .

Then, after chamfering the gear 12, remove the chuck of the gear 12, install the setting gauge 20 in place of the gear 12 on the processing machine, and set the setting gauge 20 against the positioning pin 11 at the optimum position. 2
0, the X-axis slide member 23, Y-axis slide member 24.
The two-axis slide member 25 is moved by operating the X-axis screw shaft 28, the Y-axis screw shaft 33, and the Z-axis screw shaft 37,
X-axis, Y-axis, and X-axis slide members 23, 2 when matched
Record the scale positions of 4 and 25.

The above-mentioned preliminary measurements are performed in advance on various types and sizes of gears to be chamfered, and the results are created as a data table.

■) Setting for chamfering When chamfering a particular gear, first set the chucking rod 21 of the setting gauge 20 for chamfering, as shown in Figures 6 and 7. The positioning rod 4 is inserted into the chucking hole of the processing machine main body 1.
After adjusting the angle of the setting gauge 20 so that the blade 2 is in line contact with the side surface of the swing arm 3,
The chucking rod 21 is chucked and set.

In this case, as shown in FIG. 6, a common tool rest 50 is provided on the swing arm 3 so as to be movable in the longitudinal direction of the swing arm 3, and on the common tool rest 50, the outer end explained in FIG. It is preferable to install a tool rest 4° 5 for chamfering the inner end to support the cutters 6 and 7 for chamfering the outer and inner ends.

In this way, when the common tool rest 50 is provided, each month
The positions of the anastomoses 4 and 5 can be set by external setup.

Then, the positioning rod 42 of the setting gauge 20
The swing arm 3 is brought into contact with the common tool rest 50.
is brought into contact with the positioning rod 42 and fixed, and the common tool rest 50 is set.

On the other hand, the positioning pin 11 is set according to the data of the gear 12 obtained through preliminary measurements.
The shaft, Y-axis, and Z-axis slide members 2324.25 are sequentially positioned, and the reference hole 3 provided in the Z-axis slide member 25 is
6 is set at the optimum position corresponding to the gear 12.

As shown in FIG. 7, with respect to the set reference hole 36,
The positioning pin 11 and its mounting base 10 are adjusted so that the positioning pin 11 fits correctly, and then finally fixed.

Incidentally, it is preferable that the adjustment of each axis slide member 23, 24, 25 be performed by external setup before attachment to the processing machine 1.

By the above operations, the relative positional relationship of the outer and inner end chamfering cutters 6.7 to the gears is set correctly, and the setting gauge 20 is removed at that stage, and then
The gear 12 to be chamfered is set in a reference position according to the positioning pin 11.

After setting the gear 12, by repeating the reciprocating swing of the swing arm 3 and the intermittent rotation of a predetermined angle corresponding to the number of teeth of the gear 12, chamfering with each blade 6°7 is performed as usual. This will allow you to properly chamfer the gear.

Furthermore, when changing the type and/or size of the gear, the above setting operation may be performed in accordance with preliminary measurement data for the gear to be changed.

As is clear from the detailed explanation above, the present invention is designed to automatically set the gear chamfering machine according to the type and size of the gear. The optimum position of the positioning pin can be reproduced.

This provides a setting gauge consisting of a three-dimensional slide mechanism of the X, Y, and Z axes.

By using the setting gauge of the present invention, it is possible to easily and accurately set the chamfering machine when changing the type or size of gears, greatly simplifying the setting work compared to conventional methods. can,
Not only can the machining efficiency of chamfering be improved accordingly, but it also has the advantage that setting can be performed even by non-experts.
