[0046] As Figures 7 - 10 shown in the figure, the output unit 7 includes an output shaft 701, an output shaft housing 703, a deep groove ball bearing II 707 and a pulley 706. The output shaft 701 is a stepped shaft, and the shaft diameter of the middle shaft rod of the output shaft 701 is larger than the shaft diameters of the shaft rods at both ends.

A key groove is provided at the lower end of the output shaft 701, and the pulley 706 is fixed to the lower end of the output shaft 701 through a rectangular key. The pulley 706 of the output unit 7 and the secondary pulley 607 of the output adapter unit 8 are in the same plane and are connected by a belt. A transfer unit 8 is provided at the upper end of the output shaft 701, and the transfer unit 8 is used to connect to the reducer to realize the running-in of the reducer. The through hole II 704 in the middle of the drive shaft housing is sleeved on the middle shaft rod provided with the deep groove ball bearings II 707. A flange II 705 is provided at the upper end of the drive shaft housing, and the drive shaft housing is fixed to the workbench surface 1 through the flange II 705. The output shaft 701 is perpendicular to the workbench surface 1. The pulley 706 is located below the workbench surface 1, and the transfer unit 8 is located above the workbench surface 1. It should be noted that the output conversion unit 6 is only connected to the nearest output unit 7. To Figure 1As shown in the example, the output conversion unit 6 is connected to the output unit 7 located in the first row of the left column in the matrix. The specific connection method is to connect the secondary pulley 607 of the output conversion unit 6 with the pulley 706 of the output unit 7 through a belt. All the output units 7 in the matrix are connected in series. The output units 7 are connected by sleeved with a circular belt ring II 708 on the pulley 706.

[0047] like Figures 11 - 14 As shown, the transfer unit 8 includes a transfer shaft 801, a transfer housing 805 and a bearing 804. The shaft of the transfer shaft 801 is provided with a bearing 804, and the through hole 808 of the transfer housing 805 is sleeved on the outside of the bearing 804. The lower end of the transfer shaft 801 housing is fixedly connected to the flange II 705 of the output shaft housing 703. The lower end of the transfer shaft 801 is provided with a square slider 803, and the upper end of the transfer shaft 801 is provided with a gear shaft 802. In order to ensure that the transfer shaft 801 of the transfer unit 8 and the output shaft 701 of the output unit 7 rotate synchronously, the upper end of the output shaft 701 is set as a square groove 702, the square groove 702 is matched with the square slider 803, and the square slider 803 can be vertically slid into the square groove 702 to ensure that the transfer shaft 801 is coaxially connected with the output shaft 701. The gear shaft 802 at the upper end of the transfer shaft 801 is inserted into the input end of the reducer to achieve coaxial connection. The upper end of the housing of the transfer shaft 801 is provided with a cavity 806 that can accommodate the reducer, and the bottom of the cavity 806 is provided with a cylindrical pin 807, which is inserted into the positioning hole of the reducer to achieve positioning.

[0048] like Figure 1 As shown, two output units 7 are arranged as one group in order to ensure the stability and consistency of the utility model during running-in. Therefore, a fastening unit 9 is arranged in the middle of each group of output units 7. Figure 1 , Figure 15 and Figure 16 As shown, the fastening unit 9 includes a column 901, a pressure plate 904 and a knurled nut 907. The upper and lower ends of the column 901 are threaded rods, and the lower end threaded rod 903 is vertically screwed onto the work surface 1. A mounting hole 906 is provided in the middle of the pressure plate 904, and the pressure plate 904 passes through the upper end threaded rod 902 through the mounting hole 906. U-shaped grooves 905 are provided at both ends of the pressure plate 904, and the opening direction of the U-shaped groove 905 is perpendicular to the axis of the pressure plate 904. The size of the opening of the U-shaped groove 905 is larger than the rod diameter of the shaft rod at the output end of the reducer, and smaller than the diameter of the end face of the reducer housing. The openings of the two U-shaped grooves 905 can be set to be in opposite directions. The knurled nut 907 is screwed onto the upper end threaded rod 902 to squeeze the pressure plate 904, so that the plate surface of the pressure plate 904 can press the reducer installed on the adapter unit 8.

[0049] When the utility model is in use, a suitable adapter unit 8 is selected according to the reducer to be run-in. The adapter housing 805 of the adapter unit 8 is fixedly connected to the output shaft housing 703 of the output unit 7, and the square slider 803 at the lower end of the adapter shaft 801 in the adapter unit 8 is slid into the square groove 702 at the upper end of the output shaft 701 in the output unit 7. Then, the reducer is placed in the cavity 806 at the upper end of the adapter unit 8, so that the input end of the reducer is inserted onto the gear shaft 802 at the upper end of the adapter shaft 801 in the adapter unit 8, and at the same time, the positioning hole of the reducer is inserted onto the cylindrical pin 807 of the cavity 806. The motor controller 3 is turned on to start the driving device 5. The DC motor 501 in the driving device 5 drives the main pulley 503 to rotate. Driven by the circular belt loop I 609, the driven pulley 606 of the output conversion unit 6 drives the intermediate rotating shaft 601 to rotate, and at the same time, the intermediate rotating shaft 601 drives the driven pulley 607 to rotate. The rotation of the driven pulley 607 drives the output unit 7 of the output conversion unit 6 to rotate through the belt, and further drives other output units 7 connected in series with the output unit 7 to start rotating. Each output unit 7 that starts to work and rotate drives its respective adapter unit 8 to rotate coaxially, and finally makes the reducer coaxially connected to the adapter unit 8 start the run-in work.

[0050] The utility model uses a single DC motor 501 to control the operation of multiple output units 7, greatly reducing the production cost of the run-in platform and improving the production efficiency. At the same time, the adapter unit 8 can be replaced according to different models of the reducer, further expanding the adaptability of the run-in platform. In addition, the use of a circular belt loop and a pulley 706 for transmission reduces the production noise. The motor and the pulley 706 can flexibly adjust the input power and the transmission ratio according to different production requirements, and can also adjust and replace the adapter unit 8 to quickly respond to production requirements.
