[0094] In the embodiment, as shown in Figures 2 to 4 The upper end surface of the rack 2 is provided with a circular hole, the rotating disc 21 is located above the circular hole, and the rotating disc 21 extends beyond the boundary area of the circular hole. The rotating disc 21 is driven to rotate horizontally by a cam divider 24, the cam divider 24 is located below the circular hole and is fixed on the rack 2, and the lower end middle part of the rotating disc 21 is in supporting connection with the cam divider 24.

[0095] The cam divider 24 is driven by a speed reducer motor.

[0096] The first upper sleeve station, the oiling station, the second upper sleeve station and the press-fitting station mentioned above are all located around the circular hole.

[0097] Specifically, as an optional embodiment in the embodiment, as shown in Figure 5 and Figure 6 The tooling piece 3 comprises

[0098] A lower floating platform 31 is arranged elastically above and below the rotating disc 21;

[0099] A core seat 33 is fixed on the lower floating platform 31, and an upper end of the core seat 33 is provided with a core rod 331;

[0100] An upper floating platform 32 is arranged elastically above and below the lower floating platform 31, a middle part of the upper floating platform 32 is provided with a gear placing groove, a middle hole is arranged in the middle of the gear placing groove, and the core seat 33 is adapted to extend out of the middle hole;

[0101] A supporting block 34 is arranged at the press-fitting station;

[0102] The lower shaft sleeve 12, the gear body 11 and the upper shaft sleeve 13 are sleeved on the core rod 331, the upper floating platform 32 holds the gear body 11, the supporting block 34 supports the bottom surface of the lower floating platform 31 when the press-fitting mechanism 7 drives the lower floating platform 31 to move to a lower position, and the press-fitting mechanism 7 presses the lower shaft sleeve 12 and the upper shaft sleeve 13 into the gear body 11 together when the press-fitting mechanism 7 drives the upper floating platform 32 to move to a lower position.

[0103] Specifically, as shown in Figure 5 and Figure 6As shown, the floating structure between the lower floating platform 31 and the rotating disc 21 includes four lower springs 311 and two lower guide columns 312, two lower springs 311 and one lower guide column 312 on the left and right respectively, the lower end of the lower guide column 312 is fixedly connected with the rotating disc 21, and the upper end of the lower guide column 312 is connected with a lower stop ring after penetrating through the lower floating platform 31, so that the lower floating platform 31 is floated up and down between the lower stop ring and the rotating disc 21.

[0104] Specifically, as shown in Figure 5 and Figure 6 , the floating structure between the upper floating platform 32 and the lower floating platform 31 is basically the same, including two upper guide columns 322 and two upper springs 321, the lower end of the upper guide column 322 is fixedly connected with the lower floating platform 31, the upper end of the upper guide column 322 is connected with an upper stop ring after penetrating through the upper floating platform 32, and the two upper springs 321 are arranged between the upper floating platform 32 and the lower floating platform 31, so as to ensure that the upper floating platform 32 is floated up and down along the upper guide column 322.

[0105] Specifically, as shown in Figure 5 and Figure 6 , two upper limit blocks 35 are arranged on the lower floating platform 31, and the position of the upper floating platform 32 moving downward is controlled by controlling the height of the upper limit block 35. During press fitting, the downward moving depth of the upper floating platform 32 corresponds to the depth of the upper and lower shaft sleeves inserted into the gear body 11, so the distance needs to be accurately controlled.

[0106] Specifically, the supporting manner of the support block 34 to the bottom surface of the lower floating platform 31 can be two kinds, the first kind is that the lower floating platform 31 protrudes the rotating disc 21 in the horizontal direction, and the lower floating platform 31 is matched with the support block 34 through the protruding area to realize the support of the lower floating platform 31.

[0107] As shown in Figure 10 , the second kind is to open a perforation on the rotating disc 21, and then arrange a lower limit block 36 in the perforation, the upper end of the lower limit block 36 is fixedly connected with the lower floating platform 31, the lower limit block 36 is connected to the middle part of the lower end of the lower floating platform 31, and the lower end of the lower limit block 36 is used for matching with the support block 34, and the downward moving position of the lower floating platform 31 is controlled by controlling the position of the lower limit block 36. The advantage of the second kind is that the support block 34 can directly support the middle part of the lower floating platform 31, so that the support block 34 can stably support the lower floating platform 31, and the press fitting stability is ensured. The second kind is selected in the embodiment.

[0108] In this embodiment, the support block 34 is designed separately in the press-fitting station, which aims to avoid the downward pressure of the press-fitting mechanism 7 on the rotating disc 21. As mentioned above, the rotating disc 21 is only supported by the cam divider 24 at the middle position, so the rotating disc 21 is only suitable for horizontal rotation and cannot be vertically supported. Now the support block 34 in the press-fitting station supports the rotating disc 21 to avoid the stress on the rotating disc 21, and the downward pressure of the lower floating platform 31 is directly transmitted to the rack 2 through the support block 34. The upper end of the rack 2 is a water platform plate, and the support block 34 is fixed on the water platform plate.

[0109] Specifically, the structure of the core seat 33 and the core rod 331 is as shown in Figure 5 When the upper floating platform 32 is in the upper position, the groove bottom surface of the gear body 11 placement groove is definitely higher than the upper end surface of the core seat 33, and the height difference between the groove bottom surface and the upper end surface of the core seat 33 corresponds to the length of the lower shaft sleeve 12. When the lower shaft sleeve 12 is placed on the core seat 33, the subsequent gear body 11 placed in the gear placement groove does not interfere with the lower shaft sleeve 12, ensuring that the gear body 11 can stably contact the groove bottom surface.

[0110] Specifically, as an optional implementation manner in this embodiment, as shown in Figure 10 The press-fitting mechanism 7 comprises

[0111] a press-fitting base 71, and a press-fitting cylinder 72 arranged on the press-fitting base 71;

[0113] a press-fitting block 74 fixed below the press-fitting plate 73, and a rod hole for the core rod 331 to pass through is arranged on the bottom surface of the press-fitting block 74.

[0114] Specifically, a guide rod is arranged between the press-fitting plate 73 and the press-fitting base 71 to ensure that the press-fitting plate 73 stably moves up and down.

[0115] The press-fitting block 74 is driven by the press-fitting mechanism 7 to move up and down to apply pressure to the upper shaft sleeve 13, thereby completing the press-fitting operation.

[0116] Specifically, as an optional implementation manner in this embodiment, as shown in Figure 10 and Figure 12 A pair of spring pins 75 are arranged on the press-fitting plate 73, and the two spring pins 75 are respectively located on the two sides of the press-fitting block 74.

[0117] When the spring pin 75 is in the stretched state, the lower end thereof is lower than the lower end surface of the press-fitting block 74, so as to push the gear body 11 away from the lower end of the press-fitting block 74.

[0118] Gear body 11 is added on the front oiling station grease, so the press block 74 and the upper shaft sleeve 13 is pressed into the gear body 11 after, press block 74 with the end of the finished gear piece 1 between the overflow of lubricating grease, lubricating grease has viscosity, if not spring pin 75 will be finished gear piece 1 down to open, then the lifting of press block 74 will directly take finished gear piece 1 up, so that finished gear piece 1 from the tooling piece 3, in turn affect the later out of the material.

[0139] The oil injection control valves 62 are distributed left and right on the third base 61, and the oil outlets of the oil injection control valves 62 face the shaft hole of the gear body 11. When the tooling 3 moves from the upper tooth station to the oil feeding station, the two oil injection control valves 62 start to inject a predetermined amount of lubricating oil into the shaft hole.

[0140] On one side of the rack 2, a corresponding feeding mechanism is matched, which is used to provide the oil injection control valve 62 with lubricating oil.

[0141] Specifically, the second upper sleeve mechanism 4B in the embodiment can directly refer to the first upper sleeve mechanism 4A, and the principles of the two sleeve mechanisms are the same.

[0148] The finished gear part 1 can be conveniently discharged through the discharging mechanism 8.

[0149] The lifting of the third finger cylinder 86 can be controlled by the second lifting cylinder 84 and the slide cylinder 85.
