In addition, the hub of the roller 70 is made of plastic.

[0050] With reference to Figure 2 , and with reference to Figure 4 , Figure 4 is a perspective view of a reaming device 30 in a pulley bearing automatic assembly line of the present application. As shown in Figure 2 and Figure 4 , the reaming device 30 includes a mechanical hand 31 and a reaming assembly 32 connected to the mechanical hand 31, and the reaming assembly 32 includes a stepping motor 321, a connecting mechanism 322 connected to the stepping motor 321, and a multi-hole hot air mechanism 323 connected to the connecting mechanism 322; the multi-hole hot air mechanism 323 includes a blast controller 3231 and an air outlet pipe 3232, and a plurality of air outlet holes 3232A are arranged on the air outlet pipe 3232 in a ring shape around the axis of the air outlet pipe 3232.

[0052] With reference to Figure 5 , Figure 6 and Figure 7 , Figure 5 is a perspective view of a pressing device 40 in a pulley bearing automatic assembly line of the present application, Figure 6 is a cross-sectional structural schematic view of the pressing device 40 in the pulley bearing automatic assembly line of the present application from another angle, Figure 7 is a structural schematic view of a protective layer 45 in a pulley bearing automatic assembly line of the present application. As shown in Figure 5 , Figure 6 and Figure 7As shown, the pressing device 40 comprises a support frame 41, a telescopic cylinder 42 fixed to the support frame 41, and a limiting sleeve 43 connected to the telescopic cylinder 42, and the support frame 41 is arranged on the conveying frame 11.

The end of the limiting sleeve 43 away from the telescopic cylinder 42 is an A end, and the A end of the limiting sleeve 43 is provided with a feeding port 43A. The inner diameter of the cross section of the limiting sleeve 43 is adapted to the outer diameter of the bearing, and the limiting sleeve 43 can be sleeved on the outside of the bearing to realize that the bearing can be conveyed into the inside of the limiting sleeve 43 through the feeding port 43A and the position of the bearing can be limited in the inside of the limiting sleeve 43, so that the bearing is aligned with the bearing mounting position on the roller 70, and the pressing is facilitated.

[0054] Further, in the state that the limiting assembly 21 is provided with the roller 70, the limiting sleeve 43 and the roller 70 can move relatively, and when the limiting sleeve 43 is located above the roller 70, the A end of the limiting sleeve 43 and the roller 70 have a gap. Here, through the relationship between the A end of the limiting sleeve 43 and the roller 70, and the movement relationship between the limiting sleeve 43 and the roller 70, in the state that the limiting assembly 21 is provided with the roller 70, the limiting sleeve 43 and the roller 70 can move relatively, and the distance between the A end of the limiting sleeve 43 and the roller 70 can be minimized, so that the interference with the flow operation is avoided.

As shown in Figs. 4 and 5, Figure 8 The feeding device 50 comprises a vibrating feeder 51 and a feeding groove 52 connected to the vibrating feeder 51, and the feeding groove 52 corresponds to the feeding port 43A, and the bottom of the feeding groove 52 is at the same horizontal plane as the bottom of the limiting sleeve 43.

[0056] Further, when the limiting assembly 21 is provided with the roller 70 and located below the feeding groove 52, the feeding groove 52 and the roller 70 are in relative movement, and the feeding groove 52 and the roller 70 have a gap, so that when the limiting assembly 21 is provided with the roller 70, the feeding groove 52 can also be stably passed through, and when the limiting assembly 21 is provided with the roller 70 with the bearing pressed, the feeding groove 52 can also be stably passed through. In addition, after the bearing is embedded in the roller 70, the bearing does not protrude from the top surface of the roller 70.

[0057] Through the cooperation between the conveying frame 11 in the conveying device 10, the motor 12 connected to the conveying frame 11 and the conveying belt 13, and the plurality of limiting assemblies 21 uniformly distributed along the preset direction provided on the conveying belt 13, the hole expanding device 30 has the hole expanding assembly 32 connected to the mechanical hand 31, the hole expanding assembly 32 has the connecting mechanism 322 connected to the stepping motor 321 and the multi-hole hot air mechanism 323 connected to the connecting mechanism 322, and the pressing device 40 has the support frame 41 supported on the conveying frame 11, the telescopic cylinder 42 fixed to the support frame 41 and the limiting sleeve 43 connected to the telescopic cylinder 42, and the feeding device 50 has the feeding groove 52 connected to the vibrating feeder 51, and the hole collecting device 60 is supported on the conveying frame 11 in the conveying device 10, so that the process of assembling the roller 70 and the bearing does not need manual transfer of the material multiple times, and the processing process does not need manual operation, which effectively improves the production efficiency and reduces the roller scrap rate.

[0058] In order to facilitate understanding, the working principle of the present application is further described as follows: the pulley bearing automatic assembly line, in the working process, first, the power supply of the conveying device 10, the hole expanding device 30, the pressing device 40, the feeding device 50 and the hole collecting device 60 is turned on. Since the size of the bearing mounting hole reserved on the roller 70 is small, the material of the hub of the roller 70 is plastic, and the bearing mounting hole reserved on the hub of the roller 70 needs to be further processed and expanded before it can be assembled with the bearing; then, in the limiting device 20, the roller 70 of the corresponding specification is placed according to its specification, the roller 70 is transported to the preset sensing position of the hole expanding device 30 by the conveying device 10, the conveying device 10 is paused, the mechanical hand 31 drives the hole expanding assembly 32 to rotate, and the air outlet pipe 3232 extends into the bearing preset mounting position on the roller 70, the hot air blown out by the air blowing controller 3231 blows out along the air outlet on the air outlet pipe 3232, and rotates radially with the mechanical hand 31, so that the bearing mounting position of the roller 70 is heated and hole expanded at the same time within a preset time.

[0059] After the reaming for the preset time, the conveying device 10 is restarted, and the reamed roller 70 is conveyed to the preset sensing position of the pressing device 40, and the conveying device 10 is paused again, the feeding device 50 feeds the bearing to the top surface of the roller 70 through the feeding slot 52, and the position of the bearing is always limited on the bearing mounting position of the roller 70 under the action of the limiting sleeve 43, at this time, the mounting position sensing device receives the sensing signal, the telescopic cylinder 42 drives the pressing head 44 to press the bearing, at this time, the bearing is embedded in the roller 70;

[0060] After receiving the signal that the telescopic rod of the telescopic cylinder 42 is retracted to the initial position, the conveying device 10 is started again, the roller 70 embedded with the bearing is conveyed to the hole collecting device 60, and the hole collecting device 60 is used to bake the position of the bearing mounted on the roller 70, so as to realize the shrinkage of the hole position, at this time, the flow assembly work of the roller 70 and the bearing is completed.
