As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, the automatic buckle ring pressing device includes a supporting base 1, a positioning fixture 3 disposed on the supporting base and used for positioning a fan 2, a frame 4 connected to the supporting base 1, a buckle fixing fixture 5 disposed above the positioning fixture, and a lifting assembly for driving the buckle fixing fixture to perform lifting movement, wherein the lifting assembly includes an expansion link 61 fixedly connected above the buckle fixing fixture and a servo motor 62 connected with the expansion link 61 in a transmission manner. An electric cabinet 9 is arranged on the automatic snap ring device. The positioning fixture 3 is provided with a positioning groove matched with the shell of the fan part.

Before working, the fan 2 to be processed is firstly placed into the positioning jig 3 to position the fan, and then the retaining ring 8 is placed into a mounting position (on the retaining ring mounting hole) in the center of the top surface of the fan to wait for pressing (as shown in figure 1); the fan to be processed is a fan assembled to the press-fastening ring section.

When the fan works, the servo motor moves forward to drive the telescopic rod 61 to extend downwards, and the retaining ring fixing jig 5 is pushed to apply pressure to the retaining ring positioned at the central mounting position 8 in the top surface of the fan 2, so that the retaining ring is mounted in place; the servo motor moves in the reverse direction to drive the telescopic rod 61 to retract upwards, the retaining ring fixing jig 5 is driven to be away from the fan 2, and the fan can be taken out conveniently. And then, continuously repeating the process to complete the installation of the fan retaining ring on the production line.

In order to improve the motion stability of the telescopic rod 61 and the connected retaining ring fixing jig 5, the telescopic rod 61 is uniformly distributed and parallel, the rack 4 is provided with a horizontal positioning plate 41, and a plurality of sleeves which are used for penetrating through the telescopic rods 61 up and down are symmetrically distributed on the horizontal positioning plate 41. In this embodiment, as shown in fig. 1, the number of the telescopic rods 61 and the number of the sleeves are four, the upper ends of the four telescopic rods 61 are connected to the output end of the servo motor 62 through an upper connecting plate, and the lower ends of the four telescopic rods 61 are fixedly connected to the retaining ring positioning jig 5 through a lower connecting seat.

In this embodiment, a raised retaining ring pressing portion (not shown) is disposed at the bottom of the retaining ring positioning fixture 5, and the fan retaining ring mounting hole positioned on the positioning fixture 3 is located right below the retaining ring pressing portion.

Preferably, the retaining ring pressing part is a cylindrical structure with the same outer diameter as the retaining ring, and the retaining ring pressing part and the retaining ring mounting hole of the fan positioned on the positioning jig 3 are coaxially arranged. Due to the arrangement, abrasion to other structures of the fan when the snap ring is pressed is avoided, and the working accuracy of the snap ring positioning jig 5 is improved.

In this embodiment, the positioning fixture 3 is disposed in a V shape with an outward opening, and the included angle of the V shape is consistent with the corner of the fan housing. Since the conventional fan casing is of a square casing structure, the corner is usually 90 degrees, and the V-shaped included angle of the positioning jig 3 is also set to be a right angle. The positioning jig 3 arranged in this way can accurately position the fan shell with smaller specifications, and also avoids the influence on the pressing effect of the retaining ring caused by the deviation of the fan in the process of pressing the retaining ring.

In other embodiments, the positioning fixture 3 may be a rectangular U-shaped groove with an outward opening, and the width of the U-shaped groove is consistent with the width of the fan and is just used for being clamped into the fan.

Further, the automatic buckling ring pressing device further comprises two button switches 7 arranged on the supporting base 1, and the two button switches 7 are connected to the control circuit in series. Because the control circuit is electrically connected with the servo motor 62, when two button switches 7 which are connected in series are pressed simultaneously, the control circuit is conducted, and the automatic buckling ring pressing device is started to work. The double-button switch avoids the risk of accidentally injuring an operator due to mistaken touch of a single button starting device in the working process, and improves the use safety of the automatic pressing buckle device.

The pressing buckle ring device has high regulation and control precision and is suitable for the buckle ring pressing work of fans with different specifications. When the buckling ring pressing operation is required to be performed on fans of different specifications, the parameters of the servo motor can be adjusted, so that the lifting stroke of the telescopic rod 61 can be regulated, and the buckling ring pressing operation can be accurately completed by the buckling ring positioning jig 5.
