[0033] Specific working principle:

[0034] The working principle of bearing roller carrier mechanism 1 is as follows: The workshop conveyor line delivers bearings to the front end of bearing roller carrier mechanism 1. Because the bearing roller carrier is inclined, the bearings automatically roll downwards and stop at the first bearing stop assembly 7. The first section of the bearing roller carrier can store 3-4 bearings to be pressed and installed. After judgment by photoelectric control assembly 10, the bearing stop assembly 7 falls, allowing the bearing to roll into the middle section bearing raceway 6. The middle section bearing raceway 6 is equipped with two bearing stop assemblies 7. The storage and entry of the bearings into the rotating scanning area are controlled by the photoelectric system. When the bearing enters the scanning area, the bearing rotation mechanism 2 rises and pushes... Lift the bearing. At this time, the rotary drive assembly 19 drives the bearing to rotate. The bearing scanning device 8 above the bearing works to scan and confirm the model of the bearing to be assembled. After completion, the bearing rotation mechanism 2 falls back, the limit device opens, and the bearing automatically rolls to the end of the raceway. Then, the control system judges and opens the limit device to let the bearing roll to the bearing rear stop assembly machine 3 area. In addition, bearing booster assemblies 9 are set at the front, middle and end of the bearing raceway 6. If the bearing does not roll down automatically, the bearing booster assemblies 9 are activated and lift the raceway surface upward, so that the bearing falls to the corresponding stop position.

[0035] The working principle of the bearing back gauge assembly machine 3 is as follows: When the bearing roller mechanism 1 delivers the bearing to the bearing back gauge assembly machine 3, the bearing back gauge assembly machine 3 is in the receiving position. The bearing automatically rolls to the slot fixing position. Under computer control, two bearings are positioned. The first bearing clamping mechanism 22 is activated, the cylinder rod retracts, and the bearing pressure rod rotates and clamps the bearing. Subsequently, the second bearing clamping mechanism 24 is activated, sliding down to the state where the roller contacts the outer ring of the bearing. The cylinder rod retracts, and the bearing pressure rod clamps the bearing. Under the action of the tilting cylinder 21, the clamped bearing is tilted 90° with the tilting frame 23, putting the bearing back gauge assembly machine 3 in a tilted state. At this time, the bearing changes from a side-rolling state to an end-face-up state, allowing the next back gauge installation process to proceed.

[0036] The working principle of the bearing back gauge storage mechanism 4 is as follows: The back gauge transport fixture 26 is manually hoisted and installed on the positioning seat 27 so that the robot can grab the back gauge for back gauge assembly. Multiple bearing back gauge storage mechanisms 4 are set to meet the needs of the operation. Controlled by the computer, the robot grabs the back gauge from the back gauge storage fixture and installs it on the bearing that has been rotated 90°. When a certain number of back gauges have been grabbed, the lifting mechanism 25 automatically raises the lifting bucket 32 ​​to facilitate the robot to grab the back gauge stored at the bottom. The entire working process of the automated truck bearing assembly and conveying line system is controlled by the computer, realizing the full automation of the bearing from conveying to rotating, to bearing back gauge storage and material retrieval. The whole mechanism runs smoothly and reliably, solving the problems of high labor intensity, low efficiency, and impact on bearing pressing and subsequent processes caused by manual bearing handling and back gauge assembly in the existing technology. It also easily leads to mismatched bearing selection, which has an adverse effect on bearing pressing.
