Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting technology, and in particular to a dual-station scissor hoist. Background Technology
[0002] Traditional automotive wheel bearings consist of two sets of tapered roller bearings or ball bearings. The installation, lubrication, sealing, and clearance adjustment of these bearings are all performed on the automotive production line. This structure makes assembly difficult, costly, and unreliable at the automotive factory. Furthermore, during vehicle maintenance at repair shops, the bearings require cleaning, lubrication, and adjustment. The hub bearing unit, developed from standard angular contact ball bearings and tapered roller bearings, integrates two sets of bearings into one unit. It offers advantages such as good assembly performance, elimination of clearance adjustment, light weight, compact structure, large load capacity, pre-lubrication as a sealed bearing, elimination of external hub seals, and maintenance-free operation. It is widely used in passenger cars and is increasingly being applied to heavy-duty trucks.
[0003] During the manufacturing process of automotive bearings, a pressing operation is required. During the pressing process, lifting equipment is needed to transport the automotive bearings. Traditional lifting equipment often operates at a single station, resulting in low work efficiency. Utility Model Content

[0035] Working principle:
[0036] In use, the push cylinder 20 is activated, and the piston end of the push cylinder 20 moves the translation base plate 2. The translation base plate 2 moves the left receiving tray 7 to the loading area. Then, the left servo motor 9 is activated, and the output shaft of the servo motor 9 rotates the ball screw 10, causing the connecting rod push plate 11 to move horizontally, thereby rotating the scissor connecting rod 6. The scissor connecting rod 6 raises the receiving tray 7 to the picking height (photoelectric sensor 18 feedback signal). Then, the external robotic arm places the car bearing onto the receiving tray 7.
[0037] As the left receiving pallet 7 rises, the right receiving pallet 7 descends. The external robotic arm picks up the automotive bearing for pressing. Then, the push cylinder 20 is activated again, and the piston end of the push cylinder 20 moves the translation base plate 2. The translation base plate 2 moves the right receiving pallet 7 to the loading area. At this time, the right receiving pallet 7 rises and the left receiving pallet 7 descends. The robotic arm picks up the left automotive bearing for pressing.
