Background technique

In the engine assembly line of construction machinery, it is often necessary to assemble the engine and the gearbox together first. Since the gears of the engine and the gearbox are not in the same position when they are docked, it is difficult for the traditional conveying device to automatically adjust the gear position and dock. In the existing production method, the method often used is to fix the engine on the second half of the pallet, lift the gearbox fixed on the front half of the pallet with a crane, and then adjust the speed change by manually swinging the angle of the gearbox. After the gear position of the box is adjusted, the gearbox is manually pushed to realize the docking of the two gears. After the docking is completed, the gearbox is placed on the pallet. This method not only takes a long time to combine, but also requires a lot of labor. And because the engine and the gearbox share a pallet in this way, it is very inconvenient to transport the workpiece in the workshop.

In particular, an adjustment foot is installed on the bottom fixing frame, and the adjustment foot is fixed on the ground by steel expansion bolts to adjust the initial installation height of the entire swing roller bed.

In particular, the propulsion device is a hydraulic cylinder, the propulsion end of the hydraulic cylinder is connected to the side of the lower movable frame, and the other end is fixed on the ground through a bracket.

In particular, the jacking device is a hydraulic cylinder, the propelling end of the hydraulic cylinder is connected to the movable head and placed in the slot on the lower end surface of the movable bracket, and the other end is fixed on the upper end surface of the lower movable frame through a mounting flange.

In particular, the shaking driving device is an electric motor.

In particular, the rack is arc-shaped.

The beneficial effect of the present invention is that, compared with the prior art, the lifting and oscillating rolling bed used for the docking of the engine and the gearbox gear can automatically adjust the position of the gearbox gear when the gears of the engine and the gearbox are docked, and the adjustment is good. After the position, the combination of the two gears is automatically realized, which is not only convenient and flexible in operation, but also has a high degree of automation; it also reduces the labor intensity of workers and improves production efficiency.

detailed description

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

Please refer to Fig. 1 to Fig. 2, in the present embodiment, a kind of lifting and swinging roller bed used for connecting the engine and the gearbox gear includes a roller bed 1 for carrying the gearbox tray 2, and the roller bed 1 is opposite to the two sides. The bottom of the side is equipped with a guide seat 3 through fixing bolts, and an arc groove 18 is provided on the guide seat 3, and a support wheel assembly supporting the guide seat 3 is arranged in the arc groove 18, and the support wheel assembly includes The bracket 4 and the supporting wheel 5 rotatably installed on the bracket 4, the wheel surface of the supporting wheel 5 is stuck in the arc groove 18, and the bracket 4 is fixed on the upper end surface of the movable bracket 6 by fixing bolts. Also be fixed with rocking drive motor 7 on movable support 6, drive gear 16 is installed on the power output shaft of described rocking drive motor 7, and described drive gear 16 is engaged with the arc-shaped tooth bar 17 that is installed on guide seat 3 side, And the bottom of the movable support 6 is equipped with a jacking oil cylinder 8, the propelling end of the jacking oil cylinder 8 is connected to the movable head 9 and pushed in the draw-in groove 10 of the lower end surface of the movable support 6, and the other end is fixed on the lower part by a mounting flange. On the upper end face of the movable frame 11, the lower movable frame 11 is movably assembled on the end face of the linear slide rail 12, and the linear slide rail 12 is arranged on the bottom fixed frame 13, and the side surface of the lower movable frame 11 Propel oil cylinder 15 is installed on it.
