As shown in FIG. 1 and FIG. 2, the manufacturing precision measurement apparatus of the shaft which concerns on this invention contains the fixing jig 100 and the measuring instrument 200. As shown in FIG.

First, the fixing jig 100 has a circular beam shape having a predetermined length and is vertically installed to form a reference axis C vertically.

Here, the coupling portion 110 having a disc shape is formed at a lower end of the fixing jig 100 in a larger area.

The coupling unit 110, the upper end of the shaft (1) of the stirrer may be coupled by a plurality of fastening members.

To this end, fastening holes 111 may be formed in the edge portion of the coupling part 110 to be vertically penetrated to allow a plurality of fastening members to be penetrated therethrough.

The upper end of the fixing jig 100 is installed to be horizontally rotated in the forward and reverse directions on one end of the support 20 provided in the adjacent structure 10.

One side of the support 20, a through hole through which the upper end of the fixing jig 100 may be formed, the bearing may be installed in the through hole to reduce the rotational friction force.

On the other hand, the support 20 may be further provided with a drive unit 30 for transmitting the horizontal rotational force on the upper end of the fixing jig (100).

Here, the support or the control unit 300 to be described later may be provided with an operation switch (not shown) for rotating the fixing jig (100).

The measuring instrument 200 is provided so that position adjustment is possible in the setting position adjacent to the fixing jig 100. Here, the measuring instrument 200 may use a dial gauge.

In addition, when the fixing jig 100 rotates, the measuring device 200 may display an error value in contact with each surface of the shaft 1 to the outside.

To this end, the measuring device 200 may be provided with a clamping unit 210, a measuring unit 220, and a contact bar 230.

First, the clamping unit 210 can be installed in the adjacent structure 100 to be adjustable in position.

To this end, a separate grip member 211 or a bolt or the like for fixing to the adjacent structure 10 may be coupled to one side of the clamping part 210.

That is, the grip member 211 may grip the adjacent structure 10 or fasten the clamping part 210 to the adjacent structure 10 using a bolt.

Therefore, the position of the measuring instrument 200 may be variously changed according to the position where the clamp pin 210 is coupled to the adjacent structure 10.

The measuring unit 220 is rotatably installed in the clamping unit 210, and displays a manufacturing error value of the shaft 1 in numerals or scale.
