[0002] As shown in Figure 1 a finished gear part 1 includes a gear body 11, an upper bushing 13 and a lower bushing 12. The upper bushing 13 and the lower bushing 12 are press-fitted into the shaft hole of the gear body 11. At the same time, a distance is formed between the upper bushing 13 and the lower bushing 12, and this distance is called an oil storage groove, which is used to store lubricating grease.

[0083] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0084] This application provides an intelligent special machine for gear press-fitting, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of this application. And in the following embodiments, each embodiment has its own emphasis. For parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0085] To solve the technical problem of low production efficiency of gear parts in the prior art, an embodiment of this application provides an intelligent special machine for gear press-fitting. The following is a detailed elaboration.

[0086] As Figures 1 to 11 shown, an intelligent special machine for gear press-fitting includes

[0087] a frame 2, a turntable 21 is arranged in the middle of the frame 2, and a first bushing installation station, an oiling station, a second bushing installation station, and a press-fitting station are respectively arranged on the tabletop of the frame 2 around the turntable 21;

[0088] at least one tooling part 3, each tooling part 3 is arranged on the turntable 21, and the tooling part 3 is adapted to carry the lower bushing 12, the gear body 11, and the upper bushing 13;

[0089] a first bushing installation mechanism 4A, the first bushing installation mechanism 4A is arranged at the first bushing installation station and is adapted to place the lower bushing 12 on the tooling part 3;

[0090] a gear installation mechanism 5, the gear installation mechanism 5 is arranged at the gear installation station and is adapted to place the gear body 11 on the tooling part 3, and the gear body 11 is located above the lower bushing 12;

[0091] an oiling mechanism 6, the oiling mechanism 6 is arranged at the oiling station and is adapted to add lubricating grease into the gear body 11;

[0092] The second upper sleeve mechanism 4B is arranged at the second upper sleeve station and is adapted to place the upper shaft sleeve 13 on the tooling part 3, and the upper shaft sleeve 13 is located above the gear body 11;

[0093] The press-fitting mechanism 7 is arranged at the press-fitting station and is adapted to press the upper shaft sleeve 13 and the lower shaft sleeve 12 on the tooling part 3 into the gear body 11 together, so as to obtain the finished gear part 1.

[0094] In this embodiment, as Figures 2 to 4 shown, a round hole is formed in the upper end surface of the frame 2, the turntable 21 is located above the round hole, and the periphery of the turntable 21 extends out of the boundary area of the round hole. The turntable 21 is driven by the cam divider 24 to rotate horizontally. The cam divider 24 is located below the round hole and fixed on the frame 2, and the middle part of the lower end of the turntable 21 is supported and connected with the cam divider 24.

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

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

[0097] Specifically, as an optional implementation manner in this embodiment, as Figure 5 and Figure 6 shown, the tooling part 3 includes

[0098] The lower floating platform 31 is elastically arranged up and down on the turntable 21;

[0099] The core seat 33 is fixed on the lower floating platform 31, and a core rod 331 is arranged at the upper end of the core seat 33;

[0100] The upper floating platform 32 is elastically arranged up and down on the lower floating platform 31. A gear placement groove is formed in the middle of the upper floating platform 32, a middle hole is formed in the middle of the gear placement groove, and the core seat 33 is adapted to extend out from the middle hole;

[0101] The support 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 supports the gear body 11. When the press-fitting mechanism 7 drives the lower floating platform 31 to move to the lower position, the bottom surface of the lower floating platform 31 is supported by the support block 34. When the press-fitting mechanism 7 moves the upper floating platform 32 to the lower position, the lower shaft sleeve 12 and the upper shaft sleeve 13 are pressed into the gear body 11 together.

[0103] Specifically, as Figure 5 and Figure 6As shown in the figure, the floating structure between the lower floating platform 31 and the turntable 21 is as follows: it includes four lower springs 311 and two lower guide posts 312. There are two lower springs 311 and one lower guide post 312 on the left and right respectively. The lower end of the lower guide post 312 is fixedly connected to the turntable 21, and the upper end of the lower guide post 312 passes through the lower floating platform 31 and then is connected to the lower retaining ring, so that the lower floating platform 31 floats up and down between the lower retaining ring and the turntable 21.

[0104] Specifically, as Figure 5 and Figure 6 shown in the figure, the floating structure between the upper floating platform 32 and the lower floating platform 31 is basically the same, including two upper guide posts 322 and two upper springs 321. The lower end of the upper guide post 322 is fixedly connected to the lower floating platform 31, and the upper end of the upper guide post 322 passes through the upper floating platform 32 and then is connected to the upper retaining ring. 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 floats up and down along the upper guide post 322.

[0105] Specifically, as Figure 5 and Figure 6 shown in the figure, two upper limit blocks 35 are arranged on the lower floating platform 31. By controlling the height of the upper limit blocks 35, the position where the upper floating platform 32 moves downward is controlled. During pressing, the downward movement depth of the upper floating platform 32 corresponds to the depth at which the upper and lower bushings are inserted into the gear body 11. Therefore, this distance needs to be accurately controlled.

[0106] Specifically, there are two ways for the support block 34 to support the bottom surface of the lower floating platform 31. The first way is that the lower floating platform 31 protrudes from the turntable 21 in the horizontal direction, and the lower floating platform 31 cooperates with the support block 34 through the protruding area to realize the support of the lower floating platform 31.

[0107] As Figure 10 shown in the figure, the second way is to open a perforation on the turntable 21, and then set a lower limit block 36 in the perforation. The upper end of the lower limit block 36 is fixedly connected to the lower floating platform 31. The lower limit block 36 is connected to the middle of the lower end of the lower floating platform 31. The lower end of the lower limit block 36 is used to cooperate with the support block 34, and the downward movement position of the lower floating platform 31 is controlled by controlling the position of the lower limit block 36. The advantage of the second way is that the support block 34 can directly support the middle part of the lower floating platform 31, which can stably support the lower floating platform 31 by the support block 34 and ensure the stability of pressing. In this embodiment, the second way is selected.

[0108] In this embodiment, the reason for separately designing the support block 34 at the press-fitting station is to avoid the turntable 21 from bearing the downward pressure brought by the press-fitting mechanism 7. As introduced above, actually only the middle position of the entire turntable 21 is supported and connected to the cam divider 24. Therefore, the turntable 21 is only suitable for horizontal rotation and cannot provide vertical support. Now, the support block 34 at the press-fitting station supports the turntable 21 to prevent the turntable 21 from being stressed. The downward pressure borne by the lower floating table 31 is directly transmitted to the machine frame 2 through the support block 34. The upper end of the machine frame 2 is a horizontal platen, and the support block 34 is fixed on this horizontal platen.

[0109] Specifically, the structures of the core seat 33 and the core rod 331 are as Figure 5 shown. When the upper floating table 32 is in the upper position, the bottom surface of the gear body 11 placement groove is definitely higher than the upper end surface of the core seat 33. The height difference between the bottom surface of the groove 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 gear body 11 subsequently 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 bottom surface of the groove.

[0110] Specifically, as an alternative implementation manner in this embodiment, as Figure 10 shown, the press-fitting mechanism 7 includes

[0111] a press-fitting base 71, on which a press-fitting cylinder 72 is arranged;

[0112] a press-fitting plate 73, which is connected to the press-fitting cylinder 72 and drives the press-fitting plate 73 to move up and down;

[0113] a press-fitting block 74, which is fixed below the press-fitting plate 73, and a rod hole for the core rod 331 to pass through is opened 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 moves up and down stably.

[0115] The press-fitting mechanism 7 drives the press-fitting block 74 to move up and down, so as to apply a pressing force to the upper shaft sleeve 13 and complete the press-fitting operation.

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

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

[0118] The gear body 11 is added with lubricating grease at the previous oiling station. Therefore, after the pressing block 74 presses the upper shaft sleeve 13 into the gear body 11, there is overflowing lubricating grease between the pressing block 74 and the upper end of the finished gear part 1. The lubricating grease is viscous. If there is no spring pin 75 to push the finished gear part 1 downward, the lifting of the pressing block 74 will directly carry the finished gear part 1 upward, causing the finished gear part 1 to disengage from the tooling part 3, thus affecting the subsequent discharging.

[0119] Specifically, as an alternative implementation in this embodiment, as Figure 7 shown, the first upper sleeve mechanism 4A includes

[0120] a first base 41, which is fixedly arranged on the frame 2, and a first rodless cylinder 42 is arranged on the first base 41;

[0121] a first lifting cylinder 43, which is connected to the slider of the first rodless cylinder 42 to drive the first lifting cylinder 43 to move horizontally;

[0122] a first finger cylinder 44, which is connected to the first lifting cylinder 43 to drive the first finger cylinder 44 to move up and down. The first finger cylinder 44 is suitable for clamping the lower shaft sleeve 12.

[0123] The rodless cylinder is an existing mature product, and rodless cylinders are used in multiple stations of the special machine. Therefore, its principle structure will not be elaborated here.

[0124] Through the coordinated cooperation of the first rodless cylinder 42 and the first lifting cylinder 43, the lower shaft sleeve 12 is sleeved on the core rod 331, and finally the lower shaft sleeve 12 falls onto the core seat 33.

[0125] On one side of the frame 2, a corresponding feeding mechanism is provided, which is used to provide the lower shaft sleeve 12 for the first upper sleeve mechanism 4A.

[0126] Specifically, as an alternative implementation in this embodiment, as Figure 8 shown, the upper tooth mechanism 5 includes

[0127] a second base 51, which is fixedly arranged on the frame 2, and a second rodless cylinder 52 is arranged on the second base 51;

[0128] a first horizontal slide 53, which is connected to the slider of the second rodless cylinder 52 to make the first horizontal slide 53 move horizontally;

[0129] a vertical slide 54, which is arranged on the first horizontal slide 53 to move up and down;

[0130] The second finger cylinder 55 is arranged on the vertical sliding seat 54.

[0131] A ball screw and a linear slide rail are arranged between the vertical sliding seat 54 and the first horizontal sliding seat 53. The motor drives the ball screw to rotate. The ball screw passes through the vertical sliding seat 54, thereby driving the vertical sliding seat 54 to move up and down.

[0132] During operation, after the second finger cylinder 55 clamps the gear body 11, under the control of the second rodless cylinder 52 and the motor, the gear body 11 is placed on the floating platform 32.

[0133] On one side of the frame 2, a corresponding feeding mechanism is coordinated. This feeding mechanism is used to supply the gear body 11 to the upper tooth mechanism 5.

[0134] Specifically, as an optional implementation manner in this embodiment, as Figure 9 shown, the oiling mechanism 6 includes

[0135] A third base 61 is fixedly arranged on the frame 2;

[0136] At least one oil injection control valve 62 is arranged on the third base 61;

[0137] Each oil injection control valve 62 is adapted to inject oil into the shaft hole of the gear body 11.

[0138] The oil injection control valve 62 is an existing mature product, and its principle structure will not be elaborated here.

[0139] The oil injection control valves 62 are distributed left and right obliquely on the third base 61. The oil outlet of the oil injection control valve 62 faces into the shaft hole of the gear body 11. After the tooling part 3 moves from the upper tooth position to the oiling position, the two oil injection control valves 62 are controlled to start injecting a predetermined amount of lubricating oil into the shaft hole.

[0140] On one side of the frame 2, a corresponding feeding mechanism is coordinated. This feeding mechanism is used to supply lubricating oil to the oil injection control valve 62.

[0141] Specifically, the second upper sleeve mechanism 4B in this embodiment can directly refer to the first upper sleeve mechanism 4A. The principles of the two mechanisms are exactly the same. The second upper sleeve mechanism 4B is responsible for sleeving the upper shaft sleeve 13 onto the core rod 331.

[0142] On one side of the frame 2, a corresponding feeding mechanism is coordinated. This feeding mechanism is used to supply the upper shaft sleeve 13 to the second upper sleeve mechanism 4B.

[0143] Specifically, as an optional implementation manner in this embodiment, as Figure 10 shown, a discharging mechanism 8 is further arranged on the frame 2. The discharging mechanism 8 includes

[0144] The fourth base 81 is fixedly arranged on the frame 2, and a third rodless cylinder 82 is arranged on the fourth base 81;

[0145] A second transverse slide 83, and a second lifting cylinder 84 is arranged on the second transverse slide 83;

[0146] A slide table cylinder 85 is connected to the second lifting cylinder 84 so that the slide table cylinder 85 moves up and down on the second base 51;

[0147] A third finger cylinder 86 is connected to the slide table cylinder 85 so that the third finger cylinder 86 moves up and down, and the third finger cylinder 86 clamps the finished gear part 1.

[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 table cylinder 85. The second lifting cylinder 84 controls the large stroke, and the slide table cylinder 85 controls the small stroke. The two cooperate to enable the third finger cylinder 86 to accurately pick and place the finished gear part 1.

[0150] On one side of the frame 2, a corresponding feeding mechanism is provided, and the feeding mechanism is used to receive the finished gear part 1 transferred by the discharging mechanism 8.

[0151] Specifically, as an optional implementation manner in this embodiment, as Figure 4 shown, a positioning cylinder is arranged on the frame 2. The positioning cylinder is connected to a positioning pin 23. A positioning hole 22 is opened on the turntable 21. The positioning cylinder drives the positioning pin 23 to move up and down, and the positioning pin 23 is adapted to be inserted into the positioning hole 22, thereby limiting the turntable 21 at the target working position.

[0152] Specifically, as an optional implementation manner in this embodiment, the number of the positioning holes 22 is six, the number of the positioning pins 23 is one, and the number of the tooling parts 3 is six. The six working positions enable the turntable 21 to rotate 60° each time, and the tooling part 3 on the turntable 21 switches to a working position. The actuating mechanism at each working position then completes a predetermined action on the tooling part 3, such as placing the upper bushing 13, placing the gear body 11, etc.

[0153] For the special machine for gear bush pressing in this embodiment, to achieve intelligence, a PLC controller is also configured. The PLC controller is electrically connected to the reduction motor and is also respectively connected to the electronic control units in the first bush sleeving mechanism 4A, the gear mounting mechanism 5, the oiling mechanism 6, the second bush sleeving mechanism 4B, and the pressing mechanism 7. The PLC controller controls the coordinated operation of each mechanism to improve the intelligence level of the special machine for gear bush pressing. The intelligence of the special machine for gear bush pressing is not elaborated in this embodiment.
