[0055] Based on the above structure, in the specific implementation process of the present application, the operator places the flow jig at the starting end of the first conveyor line and inserts the pre-oiled rotating shaft bracket and the rotating shaft body into the two elastic jigs of the flow jig respectively; the flow jig is conveyed to two automatic assembly mechanisms on the first conveyor line; the two automatic assembly mechanisms press the rotating shaft brackets and the rotating shaft body in the two elastic jigs together respectively; the two flow jigs are conveyed to the positions of four swing running-in mechanisms on the first conveyor line; the four swing running-in mechanisms simultaneously drive the rotating shaft brackets in the four elastic jigs of the two flow jigs to swing and run-in; the flow jig is conveyed to one of the oil blowing mechanisms on the first conveyor line; the oil blowing mechanism blows oil for the first time on the rotating shaft brackets and the rotating shaft body in the two elastic jigs of the flow jig; after that, the first conveyor line conveys the flow jig to the fourth conveyor line The mobile jig is on the line, and the fourth conveyor line will move to be aligned with the second conveyor line. At this time, the fourth conveyor line conveys the mobile jig to the second conveyor line and when the second conveyor line conveys the mobile jig to another oil blowing mechanism, the oil blowing mechanism blows oil for the second time on the rotating shaft bracket and the rotating shaft body in the two elastic jigs of the mobile jig. When the second conveyor line conveys the mobile jig to the two torque detection mechanisms, the two torque detection mechanisms drive the rotating shaft bracket in the two elastic jigs of the mobile jig to swing to realize torque detection. When the second conveyor line conveys the mobile jig to the unloading and handling mechanism, the unloading and handling mechanism will unload the assembled rotating shaft product. When the mobile jig reaches the third conveyor line, the third conveyor line will move to be aligned with the first conveyor line. At this time, the third assembly line conveys the empty mobile jig to the first belt conveyor line.

[0057] refer to Figure 1 As shown, the first conveyor line, the second conveyor line, the third conveyor line and the fourth conveyor line of the present application are all composed of two belt lines 15 arranged side by side. In actual use, the mobile fixture of the present application needs to be arranged on the two belt lines on the first conveyor line, or the second conveyor line, the third conveyor line or the fourth conveyor line, so that it can be moved accordingly.

When the first conveyor line transports two flow jigs to the bottom of the four first gantries, the four second cylinders will drive the four frames to descend until the four rotating shaft brackets are inserted into the first slots of the four running-in heads. Then, the four rotary motors control the rotation of the four first rotating plates. At this time, the rotating shaft bracket can be driven to rotate for swing running-in. During this process, the four running-in heads can realize longitudinal and lateral movement, ensuring that the running-in heads have room for movement during the running-in process and will not cause damage to the rotating shaft bracket and the rotating shaft shaft body.

[0062] Based on the above cooling mechanism, the present application also includes a code scanning mechanism 90, which includes two code scanners 91 arranged on the machine platform on the other side of the middle end of the second conveyor line. During the cooling process of the two rotating shaft brackets and the two rotating shaft bodies on the flow fixture, the two code scanners will scan the information codes on the two rotating shaft brackets. It should be noted here that the rotating shaft bracket of the present application is laser engraved with information codes in advance.

[0063] refer to Figure 8 As shown, the elastic fixture of the present application includes a T-shaped rotating part 211 that passes through the flow fixture and extends to the upper and lower sides, a square groove 2111 opened at the bottom of the T-shaped rotating part, an axle seat 212 arranged above the T-shaped rotating part, a socket 2121 axially opened on the axle seat, a limit ring 23 sleeved under the T-shaped rotating part, and a spring 24 sleeved on the T-shaped rotating part between the limit ring and the flow fixture. In the specific implementation, the operator first inserts the shaft body of the rotating shaft into the socket, and then assembles the rotating shaft bracket on the rotating shaft.

[0066] The torque detection assembly includes a fourth cylinder 721 arranged on the machine platform between the two second gantries, a docking plate 722 connected to the top of the fourth cylinder and driven to rise and fall by the fourth cylinder, a docking block 723 arranged above the docking plate for connecting with the flow fixture, two torque meters 724 arranged on the docking plate on both sides of the docking block, docking shafts 725 respectively arranged on the two torque meters, and two square protrusions 7251 respectively arranged above the two docking shafts and corresponding to the square grooves at the bottom of the two T-shaped rotating parts.

[0067] Continue to refer Figure 9-10As shown, the docking block of the present application is provided with two positioning PIN needles 7231, and the flow fixture is provided with two pinholes 22. When the fourth cylinder drives the docking plate to rise, the two positioning PIN needles are respectively inserted into the two pinholes.

[0068] When the second conveyor line conveys the mobile jig to the bottom of the two second gantries, under the drive of the fourth cylinder, the docking block on the docking plate will move upward so that the two positioning PIN needles are inserted into the two pinholes to achieve docking with the mobile jig, and the two square protrusions on the two docking shafts will be respectively inserted into the square grooves at the bottom of the two T-shaped rotating parts. At the same time, under the drive of the two third cylinders, the two second frames perform a descending action in the two second gantries so that the two rotating shaft brackets in the elastic jig are inserted into the second slots. Under the drive of the two reduction servo motors, the two rotating shaft brackets will be twisted. During this process, the two torque meters will detect the torque value in real time. If the detected torque value is within the set value range, then the rotating shaft product is a qualified part. If the detected torque value is not within the set value range, then the rotating shaft product is an unqualified part, and when the servo rotary motor drives the second rotating plate to rotate, the twisting head can realize longitudinal and lateral movement, ensuring that the twisting head has room for movement during the torque detection process and will not cause damage to the rotating shaft bracket and the rotating shaft body.

Then, the vertical drive module drives the second lifting plate to descend, and the two cylinder clamps grab the two rotating shaft products, and according to the detection results of the torque detection mechanism, the qualified products are placed in the corresponding sorting discharge boxes, and the unqualified products are placed in the corresponding sorting discharge boxes.

[0070] Continue to refer Fig.11As shown, in order to ensure that the rotating shaft product is in a better assembly state after the running-in process and torque test, the present application also includes a re-pressing mechanism 100, which includes a sixth cylinder 101 arranged on the second lifting plate between the two fifth cylinders, a re-pressing block 102 connected to the sixth cylinder drive, and a second pressing groove (not shown, the same shape as the first pressing groove) opened at the bottom of the re-pressing block and matched with the rotating shaft body. According to the detection result of the torque detection mechanism, before sorting and unloading the rotating shaft products, the two second longitudinal drive modules cooperate to drive the transverse drive module to move longitudinally, and the transverse drive module drives the vertical drive module to move transversely. When the re-pressing block reaches above the rotating shaft product with qualified torque, the vertical drive module drives the second lifting plate to descend. After it is in place, the sixth cylinder will drive the re-pressing block to descend, and the second pressing groove will re-press the rotating shaft bracket and the rotating shaft.
