Next, as shown in FIG. 12 , the actuator 70 rotates the fixed shaft 73 so that the pin housing 40 and the alignment members 10 , 20 , 30 rotate about the rotation axis. Then, as shown in FIG. 12 , the second reference pin 22 and the second bolt pin 23 are respectively connected to the reference pin hole 222 during the rotation of the pin housing 40 and the alignment members 10 , 20 and 30 . When positioned on a straight line with the bolt hole 224 and the second alignment member 20, the first support members 50 elastically supporting the second alignment member 20, the pressing force of the actuator 70 applied thereto is momentarily released and elastically restored. .

Due to this, the second alignment member 20, as shown in Fig. 12, by the elastic force of the first support member 50 applied through the second support portion 26 along the guide shaft 60 flange 220), the second reference pin 22 and the second bolt pin 23 are inserted into the reference pin hole 222 and the bolt hole 224, respectively. Then, the second crankshaft 200 is in a state in which it can be rotationally driven together with the second alignment member 20 .

Meanwhile, the second proximity sensor 84 may specify that the prepared crankshaft 400 is the second crankshaft 200 by detecting the sliding movement of the second sliding plate 21 .

Thereafter, the actuator 70 additionally rotates the fixed shaft 73 so that the second crankshaft 200 rotates. Through this, the actuator 70 may align the phase of the second crankshaft 200 so that the reference pinhole 222 comes to a predetermined 0 degree position. However, the present invention is not limited thereto, and in the case where the second reference pin 22 is omitted and only the second bolt pin 23 is provided, the actuator 70 has the second crankshaft 200 based on the bolt hole 224 . ) can also be aligned.

Next, the actuator 70, as shown in FIG. 13, the pin housing 40 and the alignment members 10, 20, 30 are reversed, the second reference pin 22 and the second bolt pin 23 The fixed shaft 73 is moved backward so as to be drawn out from the reference pin hole 222 and the bolt hole 224 of the second crankshaft 200, respectively. In addition, in the process in which the pin housing 40 and the alignment members 10 , 20 , and 30 are moved backward, the pin housing 40 and the guide shaft 60 are positioned at their normal positions by the elastic force applied from the second support member 79 . is restored, and the alignment members 10 , 20 , and 30 are restored to their original positions by the elastic force applied from the first support members 50 .

As described above, the phase aligning device 1 may specify the type of the crankshaft 400 , and may align the phases of various types of the crankshaft 400 . Accordingly, the phase alignment device 1 can reduce the cost required to separately provide a type specific device for the crankshaft 400 . In addition, the phase aligning device 1 may reduce the installation cost and installation space of the phase aligning device compared to a case in which a plurality of phase aligning devices capable of aligning the phases of a single type of crankshaft 400 are separately installed.

In the above, although the present invention has been described with reference to limited embodiments and drawings, the present invention is not limited thereto and will be described below with the technical idea of the present invention by those of ordinary skill in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims.
