Description

Technical Field

[0001] The utility model relates to the technical field of rotary device equipment, in particular to a synchronous rotary device of a large hydraulic press. Background Art

[0002] In the currently known large hydraulic presses, since there is no synchronous rotation device, it is very inconvenient to use the hydraulic press to process certain special workpieces, such as heads, hulls and other bent parts. That is, not only is it time-consuming and laborious to adjust the workpiece during processing, but it is also difficult to control the accuracy.

[0003] The application number is CN01279583.6, which discloses a synchronous rotary device for a large hydraulic press. The device comprises a support mounted on the left arm of the hydraulic press; a synchronous driving gearbox is fixedly mounted on the right arm of the hydraulic press, on which upper and lower intermediate shafts are connected, and the upper and lower intermediate shafts respectively enter the upper and lower worm gear boxes mounted on the right arm of the hydraulic press, and the upper and lower worm gear boxes are respectively mounted on the support through chains, and each support and the support on the left arm of the hydraulic press are each mounted with a smooth bar; a transmission box through which the smooth bar passes is mounted on the oil tank of the upper beam of the hydraulic press, and is connected to the intermediate shaft with gears through a coupling; a transmission shaft with gears is mounted on the main cylinder of the hydraulic press, and a gear is also mounted on the lower end thereof; a rotary upper pressure head and a gear are mounted on the plunger of the main cylinder of the hydraulic press; a mobile workbench is mounted on the lower beam of the hydraulic press, on which a rotary workbench is mounted, and an internal gear is mounted below it, and a rotary gearbox with gears is mounted below the mobile workbench. Since a synchronous rotary device is added to the large hydraulic press, the hydraulic press has the characteristics of convenient processing and time-saving and labor-saving adjustment of workpieces during processing, and achieves the purpose of reducing labor intensity, improving productivity and high precision.

[0004] The synchronous rotating device of a large hydraulic press disclosed in the above document has the following defects: when a workpiece needs to be installed on the rotating device for processing, the structure cannot effectively fix the workpiece on the rotating structure, resulting in a significant reduction in the quality and efficiency of the processing assembly on the workpiece.

[0005] It can be seen from this that the existing synchronous rotation device does not have the function of effectively fixing the workpiece, and it is necessary to improve the existing deficiencies and provide a function that can effectively fix the workpiece to facilitate processing.
