[0021] like Figure 2 and Figure 4As shown, the driving assembly includes a rack 9, a gear 10 and an electric shaft 11. The racks 9 are symmetrically slidably connected to the sides of the upper parts of the two placement racks 6 that are close to each other. The left end of the rack 9 on the upper side of the same placement rack 6 is fixedly connected to the clamping block 7 on the left side, and the right end of the rack 9 on the lower side of the same placement rack 6 is fixedly connected to the clamping block 7 on the right side. An electric shaft 11 is rotatably connected between the upper parts of the two placement racks 6. Gears 10 are symmetrically fixedly connected to the rotating axis of the electric shaft 11 front and back. The gear 10 is located between the upper and lower racks 9 on the same side. The gear 10 meshes with the rack 9. By controlling the operation of the electric shaft 11, the front and rear gears 10 are synchronously driven to rotate clockwise. Under the meshing action of the gear 10 and the rack 9, the left and right clamping blocks 7 are moved toward the side close to each other until the left and right clamping blocks 7 contact the left and right sides of the main shaft body 61, thereby clamping the main shaft body 61.

[0025] Working principle: When a durability test is required, first, the two sides of the main shaft body 61 are placed on the top of the two placement frames 6 respectively, and located between the left and right clamping blocks 7, and then the electric shaft 11 is controlled to work, and the front and rear gears 10 are synchronously driven to rotate clockwise. Under the meshing action of the gear 10 and the rack 9, the left and right clamping blocks 7 are moved toward the side close to each other, and the clamping blocks 7 drive the guide rod 8 to move toward the side close to each other. Under the guiding action of the guide rod 8, the front and rear clamping blocks 7 can be moved synchronously until the left and right clamping blocks 7 contact the left and right sides of the main shaft body 61, thereby clamping the main shaft body 61. Secondly, the threaded rod 15 is rotated to move the threaded rod 15 downward along the connecting frame 12. Under the guiding action of the connecting rod 14, the threaded rod 15 drives the lower pressure plate 13 to move downward until the bottom of the lower pressure plate 13 contacts the top of the main shaft body 61, thereby vertically adjusting the main shaft body 61. The limit on the top, then the flat belt 5 is wound around the pulley 4 and the main shaft body 61, and then, the connecting frame 12 is pulled left, and the connecting frame 12 drives the two placement frames 6 and their upper components to slide left, so that the main shaft body 61 drives the left side of the flat belt 5 away from the detection motor 3, so that the flat belt 5 is tightened until the flat belt 5 between the pulley 4 and the main shaft body 61 is straightened and maintains an appropriate tension, and then the fixing screw 18 is rotated to move the fixing screw 18 forward until the front end of the fixing screw 18 contacts the rear part of the rear side slide rail 16, thereby realizing the limit of the placement frame 6, and then the detection motor 3 is controlled to work, and the main shaft body 61 can be subjected to a durability test through the transmission action of the pulley 4 and the flat belt 5; in this way, the distance between the placement frame 6 and the detection motor 3 can be adjusted according to the specifications of the main shaft body 61, so that the flat belt 5 can meet different detection needs, the detection is convenient, the operation is simple, time and labor are saved, and work efficiency is improved.
[0026] After the detection is completed, the detection motor 3 is controlled to stop working, so that the pulley 4 and the flat belt 5 stop driving the main shaft body 61 to rotate, and then the fixed screw 18 is reversed to make the fixed screw 18 move backward and reset and disengage from the rear slide rail 16, thereby releasing the limit on the placement rack 6, and then the connecting frame 12 is pushed to the right, and the connecting frame 12 drives the two placement racks 6 and their upper parts to slide and reset to the right, so that the main shaft body 61 drives the left side of the flat belt 5 to approach the detection motor 3, so that the flat belt 5 is relaxed, and then the flat belt 5 is removed, and then the threaded rod 15 is reversed, and the threaded rod 15 moves upward , driving the lower pressure plate 13 to move upward and reset and disengage from the main shaft body 61, thereby releasing the vertical limit of the main shaft body 61, and then controlling the electric shaft 11 to work, synchronously driving the front and rear gears 10 to rotate counterclockwise, and under the meshing action of the gear 10 and the rack 9, the left and right clamping blocks 7 move toward the side away from each other and reset and disengage from the main shaft body 61, thereby releasing the clamping of the main shaft body 61, and then removing the main shaft body 61, repeating the above steps, and the durability test of the next main shaft body 61 to be tested can be carried out.
