A detection mechanism is provided at the next station of the slot hole mechanism 5. As shown in Figures 1 and 2, the detection mechanism includes a height difference detection mechanism 61, a first inner hole detection mechanism 62 and a second inner hole detection mechanism 63. The height difference The detection mechanism 61 measures the axial height difference L1 between the end face of the lower bushing 300 close to the large diameter end of the output shaft 100 and the large diameter end face of the output shaft 100. The first inner hole detection mechanism 62 measures the height difference L1 of the lower bushing 300. The inner hole diameter R1 is measured, and the second inner hole detection mechanism 63 measures the inner hole diameter R2 of the upper bushing 200 . For example, L1 is 2.5㎜, the error is 0.5㎜, R1 is 11㎜, the maximum value of the aperture increase shall not exceed 0.05㎜, R2 is also 11㎜, and the maximum value of the aperture increase shall also not exceed 0.05㎜. The height difference detection mechanism 61 , the first inner hole detection mechanism 62 and the second inner hole detection mechanism 63 all include a detection head 71 , a lifting detection platform 72 and a detection base 73 . The detection head 71 has a pressure fitting that fits the end of the output shaft 100 On the end face, the detection head 71 is arranged on the lifting detection platform 72 , and the detection base 73 is arranged corresponding to the detection head 71 . Among them, the detection head 71 of the height difference detection mechanism 61 is a displacement sensor detection head 71, and the detection heads 71 of the first inner hole detection mechanism 62 and the second inner hole detection mechanism 63 are pneumatic measuring instrument detection heads 71;

At least one transfer mechanism is provided. The transfer mechanism includes a transfer manipulator 83. The transfer manipulator 83 performs clamping or releasing actions. The transfer manipulator 83 is provided on the lifting mechanism 82 that moves up and down. The lifting mechanism is provided on the traverse mechanism 81. The traverse mechanism can move laterally along the flow processing path of the output shaft 100 . In this embodiment, six workstations are provided (the press-fitting mechanism includes two workstations, a primary press-fitting unit 31 and a secondary press-fitting unit 32, one workstation of the slotted hole mechanism 5, and the detection mechanism includes a height difference detection mechanism 61, For example, one to seven transfer manipulators 83 can be provided. If one transfer manipulator 83 is provided, the transfer manipulator 83 will pass through the workstation one by one. position, correspondingly, the lateral movement distance of the traverse mechanism 81 is relatively long, and only one output shaft 100 can be pressed and installed in one unit time. If seven transfer manipulators 83 are provided, each transfer manipulator 83 only needs to move back and forth laterally on two adjacent stations to complete the bushing pressing, bushing drilling and inspection processes of the output shaft. Correspondingly , the lateral movement distance of the traverse mechanism 81 is equal to the distance between adjacent work stations, and the press-fitting of six output shafts 100 can be completed in one unit time. When multiple transfer manipulators 83 are provided, one transfer manipulator 83 is respectively provided on the plurality of lifting mechanisms 82 , and the plurality of lifting mechanisms 82 are arranged on the same one or more traverse mechanisms 81 . In view of the sequential cooperation relationship between each station, the next station can only accept the output shaft 100 that has been processed on the previous station only if it is vacant. Therefore, there is a synchronization in the processing speed of each station. In order to better To achieve this kind of synchronous linkage, in this embodiment, the preferred implementation method is to provide multiple lifting mechanisms 82 on one traverse mechanism 81, and to provide a transfer manipulator 83 on each of the multiple lifting mechanisms 82. In addition, in order to achieve synchronous processing of six stations, the number of transfer robots is one more than that of the six stations, that is, seven transfer robots 83 are provided. When there is a corresponding transfer robot 83 at any of the aforementioned stations, the remaining There is also a corresponding transfer robot 83 at the work station. For ease of explanation, the seven transfer robots 83 are numbered 1-7 in sequence according to the process. In this way, the lateral movement distance of the traverse mechanism 81 is equal to the distance between two adjacent work stations, and it can reduce the difficulty of controlling the synchronous lateral movement of the seven traverse mechanisms 81;

Furthermore, when the transfer robot 83 is at a specific work station, in order to facilitate the processing of the output shaft 100, the output shaft 100 needs to be rotated. For example, when drilling the bushing, in order to facilitate the drilling, the output shaft 100 is rotated 180° so that the large diameter end of the output shaft 100 faces upward. For another example, after the inner hole of the lower bushing 300 is inspected, In order to facilitate inspection of the inner hole of the upper bushing 200, the output shaft 100 is rotated 180° so that the large-diameter end of the output shaft 100 faces downward. The rotation of the output shaft 100 is set according to the process requirements, and the transfer manipulator 83 is provided through a rotating mechanism on the lifting mechanism 82 corresponding to the station that needs to be rotated. The rotating mechanism includes a rotating cylinder 84;

In addition, during the press-fitting and testing process of the output shaft 100, there may be unqualified products. Specifically, the press-fitting mechanism is provided with a pressure sensor 413. When the pressure detection fails, the unqualified products need to be eliminated. The detection mechanism is configured with three When any one test fails, the unqualified products also need to be eliminated. Therefore, recycling bins 9 are provided between workstations. Specifically, between the primary press unit 31 and the secondary press unit 32, between the secondary press unit 32 and the hole mechanism 5, between the height difference detection mechanism 61 and the first inner hole detection mechanism 62, and between the first inner hole Recycling buckets 9 are respectively provided between the detection mechanism 62 and the second inner hole detection mechanism 63 and behind the second inner hole detection mechanism 63. When the transfer manipulator 83 is transferring, the clamped output shaft 100 is released, and the output shaft 100 can be dropped into the recycling bin. Inside the barrel 9.

It should be noted that in this embodiment, the lateral movement and lifting movement required before various types of manipulators perform picking and placing operations are all existing technologies. For example, the extension, retraction, downward movement, and upward movement of the reset manipulator 55 only require The reset manipulator 55 is set on the traversing linear guide rail that is close to and away from the clamping head 513 in the horizontal direction. The traversing linear guide rail is then set on the lifting linear guide rail. The lifting detection platform 72 adopts a linear guide rail, and the traversing mechanism 81 adopts a linear guide rail. The motor guide rail and the lifting mechanism 82 adopt linear modules.
