The inner diameter measuring mechanism 22 of the shaft component is provided on the back surface of the flat plate 21 (the opposite surface of the roll 2). As shown in FIGS.
3 is provided. Each of the inner diameter measuring fingers 23 is provided so as to protrude from the center of the turntable 24 toward the center of four sliders 25 that can slide only in the vertical and horizontal directions. The four sliders 25 are connected to the turntable 24 via links 26, respectively. For this reason, if the rotary disk 24 is rotated by the cylinder 27, each inner diameter measuring finger 23 opens and closes by an equal distance from the position in FIG. 9 to the position in FIG. Therefore, the shaft component clamping mechanism 1
If the inner diameter measuring fingers 23 are inserted into the shaft part 12 clamped at 1 in a contracted state and then expanded, the inner diameter of the shaft part 12 can be accurately measured. Reference numerals 28 and 29 denote the inner diameter measuring mechanisms as Y, respectively.
It is a cylinder for adjusting the position in the Z direction.

[Outer Diameter Measuring Mechanism of Roll Shaft Section] The outer diameter measuring mechanism 30 of the roll shaft section is provided on the surface of the flat plate 21 (the surface on the roll 2 side), and as shown in FIG. An L-shaped gauge 31 is provided which can be opened and closed in the direction (Z-axis direction) and the Y-axis direction. The L-shaped gauge 31 can be moved in a vertical direction by a cylinder 32 and can be moved in a Y-axis direction by a cylinder 33. Further, a gauge block 35 that can be moved in the vertical direction by the cylinder 34 and a gauge block 37 that can be moved in the Y-axis direction by the cylinder 36 are provided so as to be opposed thereto. By automatically opening and closing these, the outer diameter of the shaft of the roll 2 placed horizontally on the roll table 1 can be measured as shown in FIGS. The measurement of the outer diameter of the shaft portion of the roll 2 is performed at many positions on the axis while moving the vertical column 20 in the X-axis direction.

[Heating Mechanism for Shaft Parts] In addition to the above, a heating mechanism 40 for shrink-fitting the shaft parts is provided on the traveling carriage 4. This shaft part heating mechanism 40
Is composed of an I-shaped core 41 inserted into the shaft component 12 clamped by the shaft component clamping mechanism 11 as shown in FIGS. 2 and 14, and a U-shaped core 42 in contact with the I-shaped core 41 at right angles thereto. Things. When the U-shaped core 42 is brought into contact with the side surface of the I-shaped core 41 as shown in FIG. 14, a closed circuit is formed, so that the shaft component 12 can be heated to a temperature at which the shaft component 12 can be shrink-fitted by electromagnetic induction heating.

[Operation] Next, the operation of the apparatus of the present invention will be described. First, the traveling vehicle 4 travels to the shaft component supply position 5, and the shaft component 12 is set on the shaft component clamping mechanism 11. Then, the vertical column 20 of the traveling vehicle 4 moves on the traveling vehicle 4 in the X-axis direction until the inner diameter is measured as shown in FIG. After inserting it into the
Automatically measure the inner diameter of 2.

Next, the traveling vehicle 4 travels while heating the shaft component 12 to the target roll placing table 1 and stops. Then, as shown in FIG.
Moves greatly toward the roll 2, and the outer diameter measuring mechanism 30
Automatically opens and closes the L-shaped gauge 31, gauge block 35, gauge block 37, etc.
The outer diameter of the shaft portion is measured at a number of positions.

In this way, the measurement of the inner diameter of the shaft part 12 and the outer diameter of the shaft part of the roll 2 is completed, and it is confirmed that there is no mistake in the combination of the two. To avoid. Instead, the inner ring presser mechanism 1
4 moves forward as shown in FIG. 16, and applies three pressing fingers 17 a to 17 c to the inner ring of the shaft component 12 set in the shaft component clamping mechanism 11. Further, the inner ring holding mechanism body 16 of the inner ring holding mechanism 14 moves forward and inserts the shaft component 12 into the shaft portion of the roll 2. This forward speed is automatically variable by a combination of a fixed amount movement by the inverter control of the motor and a recognition position movement by the servo control.

At this time, the three pressing fingers 17a
The reaction force received by the １７17c is detected by a number of load sensors, and the insertion start position is confirmed. At the same time, the shaft component 12 is inserted into the shaft portion of the roll 2 while checking the balance of the pressing forces of the pressing fingers 17a to 17c by the load sensor. If an excessive reaction force is detected, there is a possibility that some trouble has occurred, so the insertion is stopped. If the axis of the roll 2 on the roll table 1 is inclined from the horizontal plane, this can be detected in advance by the outer diameter measuring mechanism 30. Therefore, the base 10 is inclined by the lifting jack 38 of the traveling vehicle 4, and the shaft component 12 Into the roll 2 while making it coincide with the axis of the roll 2. When the shaft component 12 is inserted to the depth detected by the outer diameter measurement mechanism 30 and the load sensor detects a predetermined reaction force, the shaft component clamp mechanism 11 is opened assuming that the shaft component 12 is correctly assembled, The traveling vehicle 4 returns to the shaft component supply position 5 again.
