In the figure, (11) is a workbench, (12) is a gear holder provided on the workbench (11) and supports the gear (8), and (13) is a shaft (13) provided on the workbench (11).
A shaft holder (l4) supporting the gear 7) is a case placed on the workbench (11) so as to cover the gear (8).

(15) is the first support provided near the workbench (11), (16) is the hydraulic ram provided on the first support (15), and (17) is the rod of the hydraulic ram (16). This is a press metal that is screwed onto the tip and reciprocates to the right in the figure when driven by a hydraulic ram (16).This press metal (17) comes into contact with the shaft (7) and aligns the shaft (7) with its axis. Press in the direction shown by the arrow in the figure. (18) is a chuck rotatably provided on the press metal (17), and this chuck (18) grips one end of the shaft (7). (19) is press gold (17) and chuck 1
8) is a ball bearing interposed between the (20) is the first support (15) across the workbench (11).
The second support (21) is a guide attached to the second support (20), and the guide (21) and the second support (20) have guide holes ( 22》
are formed continuously. (23) is the guide hole (22
) is a cylindrical feed member with a trapezoidal screw engraved on its outer circumference, and this feed member (23) is connected to a feed screw machine flI (not shown) connected to an end (not shown) Driven to reciprocate in the axial direction.
(24) is a cylindrical press receiver attached to the tip of the feed member (23), and this press receiver (24) comes into contact with the side surface of the gear (8) as the feed member (23) moves. (25) is the feeding member (23) and the press receiver (
A slide member (26) is provided at the tip of the slide member (25), and this rolling center (26) is attached to the shaft (7). It comes into contact with a center hole (not shown) formed in the end surface.

(27) is an electric motor, and 《28》 is a binion shaft rotatably installed in the gate (14).
8) is rotatably coupled to the rotating shaft of the electric fi (27) via a shaft coupling (29), and (30) is a binion shaft (
This is a pinion fixed to the gear (28) and paired with the gear (8). (31) is the first support (15), hydraulic ram (16), press metal (17), second support (20), guide (21)

In the press-fit rotating device configured as described above, when assembling the gear box, first set the gear (8) on the gear pedestal (12) and cover it with the gauge (14).Next, one end The gear (8) inside the case (14)
Place the shaft (7) on the shaft holder (13) so that it passes through the shaft (7).
Set to . With the above, the shaft (7) and gear (8)
The set is complete.

After this, the feeding member (23) is moved forward, and the press receiver (24) is moved forward.
) in contact with the side part of the gear (8). Then, the press metal (17) is advanced by driving the hydraulic ram (16>),
Press the shaft (7) in the direction of its axis (in the direction of the arrow in the figure). This causes the shaft (7) to move to the gear (
8) is press-fitted. By the way, during this pressing process, the rolling center (26) is moved backward as shown in Fig. 1 by a drive unit (not shown) such as a hydraulic cylinder, and the chuck (18) is not allowed to interfere with the shaft (7). When the pressing process is completed, move the press metal (17) and press receiver (24) back and assemble the gear box.
In this assembly process, the binion shaft (
28) and pinion (30) are installed. Next, perform a rotation test. First, as shown in Fig. 2, the rod of the hydraulic ram (16) is advanced, one end of the shaft (7) is gripped by the chuck (18) at a predetermined position, and the slide member (25) is advanced. Bring the rolling center (26) into contact with center 6 of the shaft (7). This allows the shaft (7) to rotate together with the gear (8). On the other hand, the electric motor (2F) is connected to the pinion shaft (28) via the shaft coupling (29). After completing the above settings, drive the electric motor (27) at a desired rotation speed and perform a rotation test. Press in as above. The three processes of assembly and rotation testing can be performed at one station. This eliminates the need for a crane (5), which was conventionally required for movement between each process, and reduces assembly time. Also,
Since there is only one station, space can be saved. In addition, if the workbench (11) is equipped with wheels so that it can run, it is possible to transport workpieces such as the shaft (7) and the gear (8).
Unloading can also be done without a crane, avoiding the risk of accidents caused by cranes and improving safety. In the above embodiment, the gear (8) is connected by the press-fit rotation device.
Although the shaft (7) is press-fitted into the shaft, it can also be used for other purposes, such as when disassembling the shaft (7) and the gear (8) by setting the shaft (7) in the opposite direction and pressing it during repair or repairs. In addition, in the above embodiment, the shaft (7) and the gear (8) are shown as the first and second workpieces, respectively, but the invention is not limited to this.Furthermore, the above embodiment Here, the first support column (15) and the hydraulic ram (1) are used as the press-fitting means (31).
6), press metal (1.7), second pillar (20),
Although the guide (21), the feed member (23), the feed screw mechanism, and the press receiver (24) are shown, the press-fitting means only needs to be able to press-fit the first workpiece into the second workpiece, and is not limited to the above embodiment. It is not something that will be done. For example, press gold (
17) with the feed screw mechanism, or conversely with the press holder (
24) may be moved using a hydraulic ram or the like. Furthermore, in the above embodiment, the rotating means (32) includes a chuck (18), a ball bearing (19), and a slide member (25).
), a rolling center (26), an electric motor (27), and a shaft coupling (29), but the embodiment is not limited to the above embodiment as long as it can rotate the first and second works integrated. ．． For example, the shaft (7) may be rotated by directly transmitting rotation to the shaft (7) instead of the pinion shaft (28).

Alternatively, the shaft (7) may be gripped at both ends by rotating chucks, or similarly supported at both ends by a rolling center. Further, in the above embodiment, the rotation process was performed as a product testing process, but it may also be used as a rotation processing process in which the first and second workpieces are processed during the rotation process. [Effect of the invention] As explained above, the press-fitting rotation device of the present invention has the first
Since both the press-fitting means for press-fitting the workpiece into the second workpiece and the rotation means for rotating the integrated first and second workpieces are provided, the pressing process and the rotation process can be performed at one location. This has the effect of improving work efficiency and saving space.
