The press-fitting device 100 according to a specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the following description is only an exemplary illustration and should not be construed as a limitation of the present invention.

FIG. 3 is a top view of the switch beam driving device 200 . The straddle-type single track turnout is a turnout with a special structure. The turnout beam is driven by the turnout beam driving device 200 to realize the overall transfer of the turnout beam, so as to align with the track beam to form a turnout to complete the line transfer needs of the vehicle driving line. The switch beam driving device 200 includes a motor, a reducer and a swing arm 220. The motor drives the reducer to move, and then drives the switch beam to move through the swing arm 220 connected to the reducer.

As shown in FIG. 3 , the swing arm 220 and the reducer shaft 210 of the reducer are connected by a double keyway 230. Since the key and the groove of the keyway 230 are fitted with an interference fit, and the length of the keyway 230 is relatively long, the swing arm 220 and the reducer shaft 210 have great resistance during the assembly process, and the assembly is difficult and time-consuming.

In the related art, the swing arm 220 and the reducer shaft 210 are generally assembled by hot charging (cutting torch heating) and copper rod percussion. The specific operation process is as follows: the operator first heats the swing arm 220 with a cutting torch for 10 minutes Left and right, the heating temperature is about 200 degrees. After heating, the keyway 230 will thermally expand, the interference between the key and the groove will be reduced, and the resistance will be reduced. At this time, the operator takes the copper rod and knocks the swing arm 220 along the keyway 230 Above the reducer shaft 210; because the key is relatively large, the length of the keyway 230 is 200mm, the width is 45mm, the angle between the two keyways 230 is 120 degrees, and the key and the groove are interference fit, and the manual tapping time is relatively short. The length is 2 minutes to 3 minutes, and the length is 4 minutes to 5 minutes. As a result, some swing arms 220 with too much interference may not be able to be knocked in.

The above-mentioned assembly process has many disadvantages: 1) the knocking by the copper rod belongs to point contact, that is, only one point where the swing arm 220 is in contact with the reducer shaft 210 is knocked, and other points are not stressed, which is easy to cause uneven stress, It will cause certain damage to the key; 2) Since the shaft diameter of the reducer shaft 210 and the keyway 230 are both large, it is necessary to knock the swing arm 220 in the periphery of the reducer shaft 210 for many times. The hot swing arm 220 will gradually cool down, the expansion of the keyway 230 will gradually decrease, and the key will become more and more difficult to fit in, resulting in some swing arms 220 that cannot be assembled. laborious.

For the above problems, by press-fitting the swing arm 220 and the reducer shaft 210 by the press-fitting device 100 according to the embodiment of the present invention, the assembly quality can be improved, the assembly time can be saved, and the labor intensity of the workers can be reduced.
