[0032] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0033] Refer to Figures 1 - 10 , the present invention provides an automatic PIN pressing device for installing PIN pins on a planet carrier 3, which comprises a frame 1, a positioning device 2, a PIN pin seat 4, a downward pressing cylinder 5 and a material grabbing device 6. A downward pressing head 501 for downward pressing is provided on the downward pressing cylinder 5. In the whole process, first, the planet carrier 3 is moved to the positioning seat 204 by the material grabbing arm 601. The positioning of the planet carrier 3 is realized by the upper positioning module 201 and the lower positioning module 202 of the positioning device 2. Then, the positioned planet carrier 3 is moved to the PIN pin seat 4 filled with PIN pins by the material grabbing arm 601. After the planet carrier 3 is placed on the PIN pin seat 4, the installation of the PIN pin on the planet carrier 3 is realized under the action of the downward pressing head 501, and finally the installation of the PIN pin on a planet carrier 3 is realized. As can be seen from the above, the whole processing process has simple and clear procedures, without too much manual participation, and the overall structure is simple and the operation is simple, which well overcomes the deficiencies existing in the background technology and is beneficial to the improvement of processing efficiency.

[0034] Specifically, the positioning device 2 is composed of an upper positioning module 201 and a lower positioning module 202. Both the upper positioning module 201 and the lower positioning module 202 are installed on the frame 1. The upper positioning module 201 is fixed above the lower positioning module 202 through an upper positioning bracket, that is, they are relatively arranged. Then, the upper positioning module 201 includes an upper positioning cylinder 203, and a floating positioning head 2031 is drivingly connected to the upper positioning cylinder 203. The upper positioning cylinder 203 is used to drive the floating positioning head 2031 to move in the vertical direction. Next, the lower positioning module 202 includes a positioning seat 204, that is, above the positioning seat 204 is the floating positioning head 2031. Then, a positioning post 205 is movably installed on the positioning seat 204. When the planet carrier 3 is placed on the positioning seat 204, if the positioning post 205 can pass through the opening 301 position of the planet carrier 3, the positioning of the planet carrier 3 on the positioning seat 204 is completed. That is to say, the positioning device 2 is mainly used for the preliminary positioning of the planet carrier 3. Specifically: under the action of the grasping arm 601 of the material grasping device 6, the planet carrier 3 will be placed into the positioning seat 204. There will be a positioning groove dedicated to the placement of the planet carrier 3 on the positioning seat 204. At this time, the upper positioning cylinder 203 will drive the floating positioning head 2031 to squeeze the planet carrier 3 downward to ensure that it is completely located in the positioning groove. If the planet carrier 3 cannot be completely located in the positioning groove at this time, an alarm will be issued. Then, when the planet carrier 3 is completely located in the positioning groove, if the positioning post 205 can pass through the opening 301 position of the planet carrier 3, the positioning of the planet carrier 3 on the positioning seat 204 is completed. Among them, at least two pressure sensors are installed in the positioning groove. If one of the pressure sensors cannot collect the signal formed by the extrusion of the planet carrier 3, it means that the planet carrier 3 cannot be completely located in the positioning groove. At this time, an alarm will be issued through an alarm device. Further, the positioning post 205 includes an intermediate post 801 and a plurality of side posts 802. The plurality of side posts 802 are all arranged around the intermediate post 801. The intermediate post 801 is used to pass through the central hole of the planet carrier 3, and the side posts 802 are used to pass through the side holes of the planet carrier 3. Assuming that the positioning seat 204 completes the positioning of the planet carrier 3 at this time, then the intermediate post 801 will pass through the central hole and the side postsFurther, the positioning seat 204 includes a fixed seat 803, a first transmission seat 804, a second transmission seat 805 and a socket seat 806. The lower positioning cylinder 807 is in transmission connection with the first transmission seat 804. When the lower positioning cylinder 807 drives the first transmission seat 804 to move, the first transmission seat 804 drives the second transmission seat 805 to move up and down. The socket seat 806 is installed and fixed on the second transmission seat 805. The socket seat 806 is sleeved on the positioning column 205, that is, a plurality of holes for the side column 802 and the middle column 801 to pass through are formed in the socket seat 806, and the positioning column 205 is installed and fixed on the fixed seat 803 through a base 808. When the lower positioning cylinder 807 drives the first transmission seat 804 to drive the second transmission seat 805 to move up and down, the socket seat 806 will move up and down on the positioning column 205, so that the side column 802 and the middle column 801 protrude upward or are arranged inside the socket seat 806. When it is necessary to position the planet carrier 3 placed on the positioning seat 204, the lower positioning cylinder 807 drives the socket seat 806 downward through the first transmission seat 804 and the second transmission seat 805, so that the side column 802 and the middle column 801 protrude upward, thereby realizing the positioning of the planet carrier 3. In addition, in the initial state, the height of the middle column 801 is higher than the height of the side column 802, so as to ensure that the planet carrier 3 can be preliminarily positioned on the planet carrier 3.

[0035] Next, as a preferred embodiment, the PIN pin base 4 is disposed on one side of the positioning device 2, and the PIN pin base 4 includes a bottom plate, a transfer table 901, a guide rail base 902, a forward pushing cylinder 903, and a vertical pushing cylinder 904. The guide rail base 902 is disposed on the bottom plate, the transfer table 901 is slidably mounted on the guide rail base 902, and the forward pushing cylinder 903 is disposed on one side of the transfer table 901. The forward pushing cylinder 903 is in transmission connection with the transfer table 901. A PIN pin hole 908 for placing PIN pins is disposed on the transfer table 901. The vertical pushing cylinder 904 is disposed at the bottom of the bottom plate, and a pushing plate 905 is in transmission connection on the vertical pushing cylinder 904. Specifically, the pushing plate 905 is movably mounted inside the bottom plate, and an intermediate seat 906 is fixedly mounted on the pushing plate 905, and the PIN pin hole 908 is disposed on the intermediate seat 906. In detail, the transmission principle of the PIN pin base 4 for PIN pins is as follows: First, when feeding, the PIN pins are first transmitted to or placed on the transfer table 901, and then driven by the forward pushing cylinder 903 to the PIN pin base 4, that is, above the vertical pushing cylinder 904. Here, it should be noted that since a pushing plate 905 with an intermediate seat 906 is movably mounted inside the bottom plate, the intermediate seat 906 is fixedly mounted on the pushing plate 905 and the intermediate seat 906 also has the same number of PIN pin holes 908. In order to install PIN pins on the planet carrier 3, the number of PIN pin holes 908 on the intermediate seat 906 is generally three. When the vertical pushing cylinder 904 drives the pushing plate 905 upward, the intermediate seat 906 will move upward synchronously with the pushing plate 905. Next, when the PIN pins on the transfer table 901 reach the position of the intermediate seat 906, the PIN pins will slide into the PIN pin holes 908 of the intermediate seat 906 along the PIN pin holes 908 of the intermediate seat 906. At this time, the vertical pushing cylinder 904 drives the pushing plate 905 downward to lower the height of the PIN pins to a position that does not affect the backward movement of the transfer table 901, and the forward pushing cylinder 903 drives the transfer table 901 to return to facilitate the subsequent placement of the planet carrier 3 on the PIN pin base 4. When the grasping device 6 places the planet carrier 3 on the PIN pin base 4, that is, on the intermediate seat 906, the vertical pushing cylinder 904 drives the pushing plate 905 upward to make the PIN pins move upward while the pressing head 501 of the downward pressing cylinder 5 presses the planet carrier 3 downward. Under the action of the forces in the up and down directions, the PIN pins are quickly and stably installed into the planet carrier 3, thereby realizing the installation and fixation between the planet carrier 3 and the PIN pins. Further, in order to facilitate the adjustment of the position of the transfer table 901, this embodiment also provides a backward pushing cylinder 907. The backward pushing cylinder 907 is in transmission connection with the forward pushing cylinder 903 to realize the movement of the entire guide rail base 902 and the transfer table 901 on the guide rail base 902 in the horizontal direction, which can better facilitate the adjustment of the position of the transfer table 901.

[0036] As a preferred embodiment, the pressing cylinder 5 is arranged above the PIN pin base 4 and the pressing cylinder 5 is mounted on the frame 1. A downward pressing head 501 for downward pressing is provided on the pressing cylinder 5. The function of the downward pressing head 501 is to match the gear structure at the top of the planet carrier 3. When the downward pressing head 501 presses downward and at this time the planet carrier 3 is placed on the PIN pin base 4 by the material grabbing device 6, since the downward pressing head 501 has a receiving cavity for receiving the gear at the top of the planet carrier 3, the downward pressing head 501 can pass through the receiving cavity when pressing downward, so that the gear at the top of the planet carrier 3 is sleeved inside the downward pressing head 501. Finally, the pressing cylinder 5 drives it downward to realize the installation between the planet carrier 3 and the PIN pin. In addition, in order to ensure the accurate positioning between the planet carrier 3 and the PIN pin when the pressing cylinder 5 presses downward, since the planet carrier 3 has been positioned under the action of the positioning device 2, that is, it can meet the installation of the PIN pin on the planet carrier 3 in this state. Therefore, at this time, only the PIN pin needs to be placed on the PIN pin base 4, the material grabbing device 6 places the positioned planet carrier 3 on the PIN pin base 4, the vertical feeding cylinder 904 drives the feeding plate 905 upward to make the PIN pin upward while the downward pressing head 501 of the pressing cylinder 5 presses the planet carrier 3 downward. Under the action of the forces in the up and down directions, the PIN pin is quickly and stably installed into the planet carrier 3, so as to realize the installation and fixation between the planet carrier 3 and the PIN pin.

[0037] Furthermore, an optical fiber detection head is also provided on one side of the pressing cylinder 5. The optical fiber detection head is used to detect whether the PIN pin is placed in the PIN pin base 4.

[0038] As another preferred embodiment, the automatic PIN pressing device of this embodiment further includes a transfer seat for transferring the planet carrier 3 and a material placement seat 7. The transfer seat is used for transferring the planet carrier 3. A first area 701 for placing the planet carrier 3 is provided on the material placement seat 7. The transfer seat communicates with the first area 701 on the material placement seat 7 so that the planet carrier 3 enters the first area 701 along the transfer seat. Further, a conveyor belt is provided on the transfer seat, and a vibrating bowl is provided at the material inlet of the conveyor belt. After the vibrating bowl loaded with a plurality of planet carriers 3 vibrates, the planet carriers 3 will flow out in sequence along the material outlet of the vibrating bowl and finally enter the conveyor belt. These planet carriers 3 will enter the first area 701 on the material placement seat 7 through the conveyor belt. Still further, a jacking cylinder 702 is provided at the lower end of the material placement seat 7. The jacking cylinder 702 is vertically arranged and is drivingly connected to a jacking rod 703. The jacking rod 703 is used to extend into the first area 701 to jack up the planet carrier 3. In addition, a positioning plate 704 is provided at the position on the positioning seat 204 that communicates with the conveyor belt, which is used to limit the position of the planet carrier 3 so that the planet carrier 3 can smoothly enter the positioning seat 204. The purpose of jacking up the planet carrier 3 is to facilitate the subsequent grasping of the planet carrier 3 by the grasping device 6.

[0039] As another preferred embodiment, the material grabbing device 6 is installed on the frame 1 and is disposed close to the positioning device 2 and the PIN pin base 4. The material grabbing device 6 includes a material grabbing arm 601. The material grabbing arm 601 is used to move the planet carrier 3 to the positioning seat 204, and the material grabbing arm 601 is further used to place the positioned planet carrier 3 into the PIN pin base 4. In this embodiment, the material grabbing device 6 has at least the following three functions: 1. Move the planet carrier 3 from the material placement seat 7 to the positioning seat 204; 2. Move the planet carrier 3 that has been positioned on the positioning seat 204 to the PIN pin base 4; 3. Take out the planet carrier 3 on which the PIN pins have been installed on the PIN pin base 4 and place it at a position for storing the finished planet carrier 3. Specifically, the material grabbing device 6 includes a left-right moving module 10, a front-back moving cylinder 11, and a lifting cylinder 12. The front-back moving cylinder 11 is drivingly installed on the left-right moving module 10, the lifting cylinder 12 is drivingly installed on the front-back moving cylinder 11, and the material grabbing arm 601 is drivingly installed on the lifting cylinder 12. The left-right moving module 10 is used to control the movement in the left-right direction, the front-back moving cylinder 11 is used to control the movement in the front-back direction, and finally the lifting cylinder 12 is used to control the movement in the up-down direction. That is to say, through the mutual cooperation among the left-right moving module 10, the front-back moving cylinder 11, and the lifting cylinder 12, the material grabbing arm 601 can be moved in the left-right, front-back, and up-down directions, greatly improving the convenience and smoothness of the material grabbing arm 601 for grabbing materials and being beneficial to the improvement of work efficiency.

[0040] Furthermore, in order to implement at least three functions of the above-mentioned material grasping device 6, the grasping arm 601 includes a base 13, a left jaw cylinder 14, a right jaw cylinder 15 and a fixed jaw 16. The left jaw cylinder 14, the right jaw cylinder 15 and the fixed jaw 16 are all installed on the base 13. The left jaw cylinder 14 and the right jaw cylinder 15 are respectively arranged on both sides of the fixed jaw 16. The fixed jaw 16, the left jaw cylinder 14 and the right jaw cylinder 15 are all used for clamping the planet carrier 3. The specific working principle is as follows: Assume that a planet carrier 3 is placed on the material placement seat 7 at this time. At this time, the planet carrier 3 will be clamped under the action of the left jaw cylinder 14, and then the left-right moving module 10 drives the grasping arm 601 to move towards the positioning seat 204, that is, move to the left. When the planet carrier 3 moves to the positioning seat 204, after the left jaw cylinder 14 releases, the planet carrier 3 will be placed on the positioning seat 204 for positioning. When the positioning is completed, the fixed jaw 16 in the middle returns to the positioning seat 204 to grasp the planet carrier 3 and move it to the PIN needle seat 4. When the planet carrier 3 completes the installation of the PIN needle, the right jaw cylinder 15 returns to the position of the PIN needle seat 4 to grasp the planet carrier 3 and move it to the position for storing the finished planet carrier 3. The moving direction of the planet carrier 3 in the above entire process is from right to left, that is, moving in the direction from the material placement seat 7 to the PIN needle seat 4. In addition, through the setting of multiple jaw cylinders, three planet carriers 3 can be processed simultaneously, greatly improving the work efficiency. The three different jaw cylinders can directly move the planet carrier 3 close to them under the action of the material grasping device 6. For example, the left jaw cylinder 14 is mainly used to grasp the planet carrier 3 on the material placement seat 7 and move it to the positioning seat 204, and then the middle fixed jaw 16 is mainly used to grasp the planet carrier 3 on the positioning seat 204 and move it to the PIN needle seat 4. Finally, the right jaw cylinder 15 is used to grasp the planet carrier 3 on the PIN needle seat 4 and move it to the position for storing the finished planet carrier 3. Through such a setting, the function of processing three planet carriers 3 simultaneously can be realized, which can well improve the work efficiency, the user experience is extremely good, and the degree of automation is high. Secondly, the jaw part of the left jaw cylinder 14 can adopt a magnet structure, and the planet carrier 3 on the material placement seat 7 is grasped by magnetic attraction, which is convenient and fast.
