Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts processing, in particular to an axle loading and unloading device. Background Art

[0002] The axle is an important part of the vehicle chassis assembly. It is usually made of round tubes as raw materials and processed by cutting, extrusion, sandblasting and other tools. After the axle is processed and formed, multiple axles need to be transported to the assembly station to be assembled with the wheel hub and suspension components. In the processing of the axle, it is usually necessary to use a loading and unloading device to perform loading and unloading operations between different processes. For example, at the end of the axle production line, after the axle is sandblasted, it is necessary to use the axle loading and unloading device to lift the axle into the anti-rust treatment tank. After the axle is rust-proofed in the anti-rust treatment tank, the axle loading and unloading device is used to lift the axle to the stacking station for stacking. In general, the axle is discharged from the sandblasting station in a sequential manner. The conveying mechanisms are arranged closely and continuously, with no gap between adjacent axles. When spraying anti-rust oil in the anti-rust treatment tank, there must be a distance between adjacent axles because the axles need to be supported on the bracket. Since the axle arrangement spacings in the two processes are different, the current practice is to hoist a single axle from the conveying mechanism of the sandblasting process to the bracket in the anti-rust treatment tank, and hoist the axle between the conveying mechanism of the sandblasting station and the anti-rust treatment tank for multiple times, so that multiple axles are respectively arranged on multiple brackets in the anti-rust treatment tank, and the anti-rust treatment of multiple axles is completed by spraying anti-rust oil once. Since the axle needs to be hoisted between the conveying mechanism and the anti-rust treatment tank for multiple times to complete one anti-rust spraying operation, the production efficiency is low.

A driving assembly is also arranged on the mounting plate, and the driving assembly includes a driving unit, a gear pivotally connected to the fixed plate, and two racks respectively fixed to the two movable plates. The two racks extend along the length direction of the mounting plate and mesh with the gears on both sides of the gears, respectively. The driving unit is used to drive one of the movable plates to move along the length direction of the mounting plate; an electromagnet for adsorbing the axle is connected to the fixed plate and the two movable plates below through a flexible connecting piece.

Specifically, a guide rail 21 extending along the length direction of the mounting plate 20 may be fixed on both sides of the lower surface of the mounting plate 20, and both sides of the movable plate 40 are respectively installed on the two guide rails 21 so that the movable plate 40 can slide along the guide rails 21. In order to prevent the movable plate 40 from falling off the guide rails 21 when subjected to Z-direction pulling force, sliders 41 with a C-shaped cross-section may be fixed on both sides of the movable plate 40, and the sliders 41 are buckled on the guide rails 21 to prevent the movable plate 40 from falling off the guide rails 21. During assembly, the sliders 41 can be installed on the guide rails 21 from the ends of the guide rails 21. A driving assembly is also provided on the mounting plate 20, and the driving assembly includes a driving unit, a gear 51, and two racks 52. The gear 51 is pivotally connected to the fixed plate 30 and is arranged in the middle position of the mounting plate 20. The two racks 52 extend along the length direction of the mounting plate 20 and are respectively fixed on the two movable plates 40, and the two racks 52 are respectively placed on both sides of the gear 51 and are meshed with the gear 51. The power output end of the driving unit is connected to one of the movable plates 40 to drive one of the movable plates 40 to move along the length direction of the mounting plate 20. When the driving unit drives one of the movable plates 40, the driving unit drives the movable plates 40 to move along the length direction of the mounting plate 20. When the movable plate 40 moves, the rack 52 connected to the movable plate 40 moves accordingly, so that the gear 51 rotates, driving the other rack 52 to move along the length direction of the mounting plate 20 so that the two movable plates 40 move along the length direction of the mounting plate 20. Since the two racks 52 are respectively placed on both sides of the gear 51, the gear 51 rotates, so that the two racks 52 move in opposite directions along the X direction shown in the figure at the same time, and then the two movable plates 40 move toward the fixed plate 30 or away from the fixed plate 30 at the same time, and the spacing between the two movable plates 40 and the fixed plate 30 is always kept equal.

The two-axis driving mechanism 10 drives the mounting plate 20 to move, so that the three electromagnets 60 adsorb the axles from above the three axles. Then, the two-axis driving mechanism 10 drives the mounting plate 20 to move above the anti-rust treatment groove. At the same time, the driving assembly drives the two movable plates 40 to move away from the fixed plate 30 to Figure 5 In the state shown, the center distance of adjacent electromagnets 60 is equal to the center distance of the bracket in the anti-rust treatment tank, so that three axles can be placed in the anti-rust treatment tank at the same time. It should be pointed out that the utility model is only explained by transferring the axle distance between the axle sanding station and the anti-rust treatment tank. In fact, the loading and unloading device of the utility model can be applied to various links of axle processing and production to adapt to the situation where the axle placement spacing between different stations is different.
