Bevel gear 2 55 is meshedly connected with bevel gear 1 54. Screw 2 56 is a bidirectional screw. Two movable blocks 57 are threadedly connected to screw 2 56. The top surfaces of the two movable blocks 57 are fixedly connected with right-angle blocks. Clamping blocks 58 are fixedly connected between the opposite surfaces of the two right-angle blocks. Two mounting grooves 59 are opened on the top surface of the pulley placement platform 1038, and the two mounting grooves 59 are arranged at the placement position of the end cover 42. The mounting grooves 59 are matched with the clamping blocks 58.

The bottom surfaces of the two movable blocks 57 are fixedly connected with connecting blocks 12. The limiting rod 2 11 passes through the connecting block 12 and is slidably connected to the connecting block 12.

[0024] Specifically, the rotation of the lead screw 1034 drives the driving wheel 51 and the driven wheel 52 to rotate, thereby driving the driven shaft 53 and the bevel gear 1 54 to rotate, and then driving the bevel gear 2 55 and the lead screw 2 56 to rotate. Since the lead screw 2 56 is a bidirectional lead screw, the two movable blocks 57 on the lead screw 2 56 will move towards each other, and the clamping blocks 58 on the top of the movable blocks 57 are close to each other. The clamping blocks 58 are elastic rubber blocks, which pass through the mounting groove 59 to clamp the outer wall of the end cover 42, thereby being able to clamp the workpiece 41 horizontally, which is beneficial to the stability of the workpiece 41.

[0025] Please pay attention to Figure 4 , Figure 5 The limiting mechanism 6 includes a hollow cylinder 61 rotatably arranged on the top surface of the cylinder body 1037, and a movable rod 62 is rotatably and slidably connected inside the hollow cylinder 61.

The movable rod 62 extends to the inside of the end cover 42. As the bottom end of the movable rod 62 rotates, the bottom end teeth of the movable rod 62 contact and rotate with the inner wall teeth of the end cover 42. After rotating to meshing, the end cover 42 and the workpiece 41 are limited to prevent them from tilting, which is conducive to keeping the workpiece 41 vertical.

[0027] Please pay attention to Figure 4 , Figure 6 A rotating ring 14 is embedded in the top surface of the pulley placement platform 1038, and the top surface of the rotating ring 14 is integrally formed with a plurality of magnets 15. A plurality of magnets 16 are embedded in the inner wall of the cylinder 1037, and the magnets 16 and 15 repel each other. A sponge block 17 is fixedly connected to the top surface of the rotating ring 14, and the sponge block 17 is arranged in a close contact with the side wall of the end cover 42. A plurality of vertical holes 18 are provided in the rotating ring 14, and the vertical holes 18 are in conflict with the sponge block 17.

[0028] Specifically, the cylinder 1037 rotates and descends, bringing the magnet 2 16 with it. Since the magnet 2 16 and the magnet 1 15 repel each other, the magnet 15 is affected by the repulsive force to rotate, driving the rotating ring 14 and the sponge block 17 to rotate. The sponge block 17 rotates in contact with the outer wall of the end cover 42, and can clean up the excess lubricant overflowed during the installation of the workpiece 41 and the end cover 42. The cleaned lubricant passes through the vertical hole 18 and is filtered through the filter screen 19 into the annular groove 20, and finally drips onto the lead screw 2 56 through the drain pipe 21, which can lubricate the lead screw 2 56.

[0029] How it works The workpiece 41 is manually placed on the workpiece placement platform of the lubrication weighing device 101, and the lubrication injection head is injected, and the weighing device on the workpiece placement platform weighs the injected lubricant; The workpiece 41 is manually placed on the workpiece placement platform of the end cap pressing device 102, and the end cap 42 is manually placed on the workpiece 41 in advance, and the pressing head moves downward to apply pressure to complete the pressing of the end cap 42; The workpiece 41 is manually placed upside down on the pulley placement platform 1038 of the rotating installation device 103.

The motor 1032 is driven to drive the screw 1034 to rotate, and drive the lifting plate 1035 and the motor 2 1036 to descend. The rotation of the screw 1034 drives the driving wheel 51 and the driven wheel 52 to rotate, thereby driving the driven shaft 53 and the bevel gear 1 54 to rotate, and then drives the bevel gear 2 55 and the screw 2 56 to rotate. Since the screw 2 56 is a bidirectional screw, the two movable blocks 57 on the screw 2 56 will move towards each other, and the clamping blocks 58 on the top of the movable blocks 57 are close to each other. The clamping blocks 58 are elastic rubber blocks, which pass through the mounting groove 59 to clamp the outer wall of the end cover 42, thereby being able to clamp the workpiece 41 horizontally. The cylinder 1037 at the bottom of the motor 2 1036 The cylinder 1037 is driven by the second motor 1036 to rotate, and the cylinder 1037 is driven to descend while rotating. When the cylinder 1037 descends, the hollow cylinder 61 is driven to descend, and the movable rod 62 also descends accordingly. The movable rod 62 extends to the inside of the end cover 42. After the bottom teeth of the movable rod 62 are engaged with the inner wall teeth of the end cover 42, the end cover 42 and the workpiece 41 are limited to avoid tilting, which is conducive to keeping the workpiece 41 vertical. The fixed ring 8 in the cylinder 1037 contacts the top surface of the inner core 43, and the rubber ring 13 contacts the two sides of the inner core 43, so that the inner core 43 can rotate with the rotation of the cylinder 1037. The inner core 43 rotates and descends, and gradually contacts with the workpiece 41 below. The inner core 43 is finally rotated to the outer wall of the workpiece 41. The installation speed is fast, and the workpiece 41 has high stability, which can improve the positioning accuracy of the assembly of the workpiece 41 and the inner core 43. The workpiece 41 is conveyed to the next box by a conveyor, and the workpiece 41 and the pulley are manually placed on the workpiece placement platform of the bearing pressing device 104. A plurality of bearings are sleeved on the bearing sleeve rod of the bearing pressing device 104. The bearings are sent to the middle of the upper pressing head and the lower pressing head through a delivery device, one at a time, and the pressing head presses the bearings to between the end cover 42 and the pulley. The workpiece placement platform is slidable, which is convenient for the placement and delivery of the pulley. The pulley is manually placed on the workpiece placement platform of the glue pressing and flanging device 105. The glue pressing and flanging device 105 can press glue on both sides of the bearing to prevent dust from falling into the bearing; The workpiece 41 is conveyed to the next box by a conveyor, and the pulley is manually placed on the workpiece placement platform of the idling torque measuring device 106. The tooth column of the idling torque measuring device 106 cooperates with the teeth of the end cover 42, and the tooth column rotates to measure the torque of the pulley when it rotates without load; The pulley is manually placed on the workpiece placement platform of the shaft rotation torque measuring device 107, the teeth of the end cover 42 are meshed with the tooth column of the shaft rotation torque measuring device 107, and after the clamping part clamps the edge of the pulley, the tooth column is rotated to test the torque when rotating with load; The gap between the pulley parts is measured by the clearance measuring device 108 and a label is affixed by the marking machine 109 .
