Technical Field

The utility model relates to the technical field of conveying devices, in particular to a lifting and steering mechanism.

Background Art

With the development of modern manufacturing industry, the application of automated material transportation machinery plays an important role in production and processing. Advanced and applicable material transportation machinery can reduce labor intensity, reduce product damage, protect workers' health, improve labor productivity and product quality, and reduce production costs. Usually, the workpieces are placed one by one on the conveyor belt mechanism and transported to the subsequent workstations. When placing the workpieces, it is not possible to ensure that the angle and direction of each workpiece are placed consistent. Therefore, it is necessary to set a mechanism to rotate the direction of the workpiece on the conveyor line. However, when the existing mechanism rotates the workpiece, the workpiece cannot leave the roller on the conveyor line, so the friction between the workpiece at the bottom and the roller causes damage to the workpiece surface.

A conveying frame 03 is fixedly installed on the top of the frame 02. A groove 04 is arranged on the conveying frame 03. A support frame 05 is arranged in the groove 04 so that the support frame 05 can be hidden in the groove 04. A driving device for driving the support frame 05 to extend out from the groove 04 and rotate is arranged in the frame 02. In the non-working state, the support frame 05 is hidden in the groove 04, which is convenient for the mobile device to move the material. In the working state, the driving device drives the support frame 05 to extend, lift the material on the conveying frame 03, and after the material is separated from the conveying frame 03, it is rotated to a set angle as required. The material separated from the conveying frame 03 is prevented from falling from the support frame 05 during the rotation process under the stability of the gantry 01, thereby reducing the need for manual rotation and improving efficiency.

Please refer to FIG. 2 , the conveyor frame 03 includes two cross bars 06 fixedly mounted on the top of the frame 02 and a connecting rod 07 fixed between the two cross bars 06. The cross bars 06 are made of channel steel. Four support rods 08 are evenly distributed on the connecting rod 07. The length of the support rod 08 is shorter than that of the cross bars 06. The groove 04 is set on the support rod 08. A plurality of notches 09 are evenly distributed on both sides of the support rod 08 and are connected to the groove 04. The support frame 05 is hidden in the groove 04 and the notch 09, so that the support frame 05 is completely hidden in the conveyor frame 03.

A plurality of rollers 10 are arranged at both ends of the support rod 08, and the two ends of the rollers 10 are rotatably connected to the two cross bars 06 through bearings. Auxiliary shafts 11 with the same structure as the rollers 10 are arranged between two adjacent support rods 08 and between the support rod 08 and the cross bar 06. The auxiliary shafts 11 are arranged on both sides of the notch 09. The material is placed on the rollers 10 and the auxiliary shafts 11, and the power components arranged in the frame 02 drive the rollers 10 and the auxiliary shafts 11 to rotate synchronously, thereby realizing the movement of the material on the rollers 10 and the auxiliary shafts 11.

As shown in FIG. 2 , a plurality of driven wheels 12 are evenly distributed on the crossbar 06 and the support bar 08, two bearing seats 13 are fixedly installed on the connecting rod 07, a power shaft 14 is rotatably installed on the bearing seat 13, a power wheel 15 is fixedly installed on the power shaft 14, a power belt 16 is sleeved on the power wheel 15 and the driven wheel 12, and the outer side of the power belt 16 abuts against the outer surface of the auxiliary shaft 11 and the roller 10. A tensioning wheel 17 is also provided on the crossbar 06, and the tensioning wheel 17 is located below the driven wheel 12 and on both sides of the power wheel 15. A sprocket wheel 18 is fixedly installed on the power shaft 14, and a driving motor 19 is fixedly installed in the frame 02, and the driving motor 19 and the sprocket wheel 18 are connected by chain transmission. When the driving motor 19 is started, it drives the power shaft 14 to rotate, thereby driving the power belt 16 to move, and the friction between the auxiliary shaft 11 and the roller 10 drives the auxiliary shaft 11 and the roller 10 to rotate, thereby driving the material to move.

A connecting plate 20 is provided in the middle of the support frame 05. A driving seat 21 is fixedly installed on the bottom surface of the connecting plate 20. A driving shaft 22 is fixedly installed on the driving seat 21. A reduction motor 23 is fixedly installed on the driving shaft 22. The reduction motor 23 is fixedly installed on the transition plate 24. The start of the reduction motor 23 can drive the driving shaft 22 to rotate, thereby driving the support frame 05 to rotate. Linear bearings 25 are fixedly installed on the four corners of the transition plate 24. An optical axis 26 is arranged in the linear bearing 25. A fixed plate 27 is fixedly installed on the end of the optical axis 26. The fixed plate 27 is located directly below the transition plate 24 and is fixedly connected to the frame 02. A lifting cylinder 28 is fixedly installed on the fixed plate 27. The output end of the lifting cylinder 28 is fixedly connected to the bottom of the transition plate 24.

The support frame 05 is then driven to rotate by the reduction motor 23 .

The support frame 05 is formed by welding and fixing square tubes distributed vertically and horizontally. The connecting plate 20 is fixed at the center of the support frame 05. When in use, after the material enters the conveying frame 03, when the material needs to rotate, the lifting cylinder 28 in the frame 02 drives the transition plate 24 to rise. During the rising process of the transition plate 24, the support frame 05 hidden in the groove 04 rises, so that the material is separated from the conveying frame 03, and the reduction motor 23 on the transition plate 24 drives the support frame 05 to rotate. Thus, the material on the support frame 05 is rotated to the set angle. When the material rotates to the set angle. The reduction motor 23 stops rotating, the output end of the lifting cylinder 28 is retracted, the support frame 05 is hidden in the groove 04, the material contacts the roller 10 and the auxiliary shaft 11 on the conveying frame 03, and the drive motor 19 in the frame 02 is started. The start of the drive motor 19 drives the roller 10 and the auxiliary shaft 11 and the rotation drives the material to leave the conveying frame 03.
