Vertical attitude adjustment mechanism for vertical assembly of large-diameter thin-walled cylinders

Abstract

The invention discloses a vertical gesture adjusting mechanism for vertical assembling of a large-diameter thin-wall part cylinder in the technical field of automatic assembling. The vertical gesture adjusting mechanism comprises a perpendicular moving part, a gesture adjusting supporting platform movably arranged on the perpendicular moving part and a base part fixedly arranged at the tail end of the perpendicular moving part. The periphery of the gesture adjusting supporting platform is in contact with the inner wall of the cylinder, a butt joint cylinder moves in the perpendicular direction and the space position and gesture of the butt joint cylinder are accurately adjusted through the gesture adjusting supporting platform. According to the vertical gesture adjusting mechanism for vertical assembling of the large-diameter thin-wall part cylinder, a perpendicular driving motor and a guide rail are used for driving a fixed platform of the gesture adjusting supporting platform so as to adjust the position of the whole gesture adjusting supporting platform in the perpendicular direction. A plurality of supporting parts which are arranged on a movable platform of the gesture adjusting supporting platform in the radial direction of the platform are used for supporting the cylinder. Position and gesture adjustment is conducted on the cylinder through a gesture adjusting mechanism of the gesture adjusting supporting platform and under the perpendicular driving of a perpendicular motor. The vertical gesture adjusting mechanism has the advantages of being compact in space arrangement, large in working range, flexible in gesture adjustment, simple in control manner and high in assembling precision and efficiency, and multiple segments of cylinders can be assembled continuously.

Description

technical field [0001] The invention relates to equipment in the technical field of automatic assembly, in particular to a vertical posture adjustment mechanism for vertical assembly of large-diameter thin-walled parts. Background technique [0002] The high-precision assembly of large-diameter and thin-walled cylinders is a key technology that is urgently needed in my country's aerospace and other fields. At present, the assembly of large-diameter thin-walled cylindrical parts mainly adopts the horizontal assembly form. The deformation caused by its own weight is overcome by adding support members inside, and the cylindrical parts are assembled and welded through their circumferential alignment. The deformation of the wall plate cannot be completely overcome by relying on the internal support members of the cylinder, and the deformation factors of the cylinder increase, the deformation control is more difficult, and the assembly accuracy is low. Moreover, during the assemb...

AI Technical Summary

Problems solved by technology

Relying on the internal support members of the cylinder cannot completely overcome the deformation of the wall plate, and lead to more deformation factors of the cylinder, more difficult deformation control, and low assembly accuracy

Moreover, during the assembly process of multi-section cylinders, horizontal assembly equipment is easy to introduce repositioning errors when replacing cylinder parts, and will lead to a significant reduction in assembly efficiency

Aiming at the problems that the horizontal assembly mechanism designed for the assembly of large-diameter cylinders occupies a large area, wastes resources, and has poor assembly accuracy, a vertical attitude-adjusting mechanism for assembly of large-diameter thin-walled cylinders is designed, which can effectively Reduce the deformation of the cylinder due to its own weight during the assembly process, and at the same time, it is suitable for continuous assembly of multi-section cylinders and the footprint is much smaller than that of horizontal assembly, meeting the assembly needs of large thin-walled cylinders

[0003] After searching the literature of the prior art, it was found that the Chinese patent document number CN103659139A was published (announced) on 2014.03.26, which disclosed a vertical cylinder assembly tool, including: a frame; a wedge iron hydraulic pressure connected to the frame type expansion and contraction mechanism; a turntable connected with the wedge iron hydraulic expansion and contraction mechanism; a rotary drive mechanism connected with the turntable to drive the rotation of the turntable and the wedge iron hydraulic expansion and contraction mechanism; The frame and the tilting mechanism connected by the wedge iron hydraulic expansion and contraction mechanism, but this equipment is only suitable for the assembly and welding of one section of the cylinder and the head, and cannot realize the assembly between multiple sections (two sections and above) of the cylinder
