Fig. 3 shows a block diagram of the processing method of the input shaft according to the present invention, and Fig. 4 shows the state of the raw material processed according to the present invention, respectively, in plan view.

As described above, the processing method of the input shaft according to the present invention, the supply step (S300) is supplied with the material (M), the standby step (S310) to pick up the material (M) by the loading means 140 and to stand by. And, the groove processing step (S320) for processing the groove on one end of the material (M) by a broaching machine (broaching), broaching one end of the material (M) through the groove processing step (S320) One end machining step (S330) to process one by one by the machine, the turning step (S340) for rotating the material is completed, the one end processing step (S330) 180 degrees, and the material (M) through the turning step (S340) The other end processing step (S350) for simultaneously processing both sides by the broaching (broaching) machine, and the other end processing step (S350) is composed of a take-out step (S360) to move the completed material (M) to the outside. .

The supply step (S300) is a step of supplying the material through the supply chute 100 from the outside. At this time, since the supply chute 100 is inclined, when the material is placed on the left end of the supply chute 100 from the outside, the material naturally rolls down to the right end of the supply chute 100. And the raw material M at this time is a state like FIG.4 (a).

The waiting step (S310) is a step of waiting to pick up the material (M) of the supply chute 100. That is, the loading means 140 picks up the material of the supply chute 100, reverses the process and waits for a predetermined time.

The groove processing step S320 is a step in which a material is processed by the first processing tool 190. In this case, first, the material M is moved to the fixing fixture 130 by the loading means 140, and the first tool holder 240 is lowered. Therefore, broaching is performed on the right side of the material by the first processing tool 190. When this groove processing step (S320) is completed, the groove of the radius (R) 5.5mm is formed on the rear right side surface of the material (M) as shown in Figure 4 (b).

When the groove processing step (S320) is completed, the material (M) is moved to the right again by the first transfer means 150 and the one end processing step (S330) is performed, in this case, the second processing tool 192 The material is processed by).

The one end processing step (S330), the first end of the process of broaching (broaching) one end of the material (M) and the first end of the process (S332), and broaching (broaching) the other end of the back of the material (M) First, a second processing process (S334) or the like.

The first process S332 is a process in which the first transfer means 150 picks up the material and rotates it in a clockwise direction, and then processes one surface by a broaching machine. That is, the material (M) is rotated about 60 ° clockwise, and then mounted on the fixed jig 130 located below the second processing tool 192, 18.5 to the material by the second processing tool 192 It is the process to make the surface processing of mm length.

The shape of the raw material in which the first processing step S332 is formed is shown in FIG. 4C.

The second processing step S334 is a process of rotating the material that has undergone the first processing step S332 in a counterclockwise direction, and then machining the other surface by a broaching machine. That is, first, the first transfer means 150 picks up the material fixed to the fixture jig 130 again, rotates it counterclockwise by 120 °, and then fixes it on the lower side of the second machining tool 192 again. It is mounted on the jig (130). In this case, the first tool holder 240 descends downward, and at this time, the rear end of the material is broached by the second processing tool 192. The state of the raw material when this second processing step S334 is completed is shown in FIG.

The turning step (S340) is a process of positioning the material as shown in (e) of FIG. 4 by rotating the material such as (d) of FIG. 4 where the one end processing step (S330) is completed by 180 degrees. At this time, the turning unit 200 is used, and the tip of the material (M) not yet processed by the turning step (S340) is also made.

In detail, once the second processing process S334 is completed, the second transfer means 160 picks up the raw material and transfers it to the turning unit 200. Then, the turning unit 200 rotates the material 180 °, so that the front and rear of the material is changed.
That is, the second transfer means 160 is moved to the right in the state as shown in FIG. 2, wherein the material M fixed to the second transfer means 160 is bitten by the turning unit 200. The second conveying means 160 is reversed (left in Fig. 2) leaving the raw material.
Next, after the material (M) is rotated by 180 degrees by the rotation cylinder provided in the turning unit 200 is to wait in that state.

Then, the third transfer means 170 picks up the material of the turning unit 200 again and mounts it on the fixing jig 130 below the third processing tool 194.
Specifically, after the turning step S340 is performed, the transfer support 280 is moved to the left side (in FIG. 1), and the third transfer means (FIG. 1) is located in front of the turning unit 200 as shown in FIG. 1. 170 is located. Then, the third transfer means 170 approaches the turning unit 200 to pick up the end of the material (M). At this time, the turning unit 200 puts the material, the third transfer means 170 is reversed (left in FIG. 2) in the state picked up the material (M) to the original position as shown in FIG.
Next, the transfer support 280 is moved to the right side (in Figure 1), the third transfer means 170 is located in front of the fixture jig 130 below the third processing tool 194 again. do. In addition, the third transfer means 170 is moved forward with the material (M) is picked up, the material (M) that was biting is mounted on the fixing jig (130) and retracted to its original position.
In this case, the other end processing step (S350) is performed.

As such, the other end processing step (S350) is a process of simultaneously processing both sides by a broaching machine (broaching) the other end of the material (M) through the turning step (S340), to process both ends of the material The other end is made of a first process (S352), and the other end of the second process (S354) for processing the other both sides.

The other end first processing process (S352) is a process of simultaneously rotating the material that has undergone the turning step (S340) in a clockwise direction, and then simultaneously machining both surfaces by a broaching machine. That is, the third transfer means 170 picks up the material of the turning unit 200 and then rotates 29.75 ° clockwise. Then, as the second tool holder 242 is lowered down, the left and right sides of the material are broached simultaneously by the third processing tool 194.

In the other end first processing process (S352), the end of the material is a process of processing so that the width of 16.96mm. Then, after the processing is completed by the other end first processing process (S352), the raw material is in the state as shown in FIG.

The second end of the second process (S354) is a process of rotating the material passed through the second end of the first process (S352) in a counterclockwise direction, and then simultaneously machining the other two sides by a broaching machine. That is, the third transfer means 170 picks up the raw material that has undergone the other end first processing process (S352) and rotates the raw material 10.5 ° counterclockwise. Then, the material is again mounted on the fixing jig 130 below the third processing tool 194. In this case, the second tool holder 242 is lowered again, and the left and right sides of the material are simultaneously cut by broaching by the third processing tool 194.

In the second end of the second process (S354), the end of the material is a process of processing so that the width of 16.96mm. Then, after the processing is completed by the second end of the second process (S354), the raw material is in a state as shown in (g) of FIG.

After the above processes are completed, the processing of the input shaft is completed, and then the take-out step (S360) for moving the material (M) to the outside of the broaching machine is performed. 4 (h) shows a state of the material taken out to the outside.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.
