Abstract

The invention relates to rotary riveting equipment for an inner drum of a washing machine. The rotary riveting equipment comprises a workbench. A lower flange plate is arranged in the middle of the upper surface of the workbench, and a plurality of first roller assemblies are arranged at intervals in the circumferential direction of the lower flange plate. Each first roller assembly comprises rollers fed by servo drive, and the axes of the rollers are parallel to the axis of the lower flange plate. A counterweight box is mounted on the rear side of the upper surface of the workbench, and a guide rail is arranged on the front side surface of the workbench. A fixing cover sliding along the guide rail is arranged on the guide rail. The fixing cover is connected with a counter weight in the counterweight box through a transmission chain. The fixing cover is driven by a servo motor at the top of the counterweight box. An upper flange plate rotating synchronously with the lower flange plateis arranged on the lower surface of the fixing cover. A plurality of second roller assemblies are arranged at intervals in the circumferential direction of the upper flange plate. The second roller assemblies and the first roller assemblies correspond to each other one by one in the vertical direction and are of the same structure. By the adoption of the rotary riveting equipment for the inner drum of the washing machine, the technical problems of uneven press-fit, poor press-fit quality, low efficiency and asynchronous rotation of the upper end and the lower end of the inner drum during rotary riveting are solved.

Description

technical field [0001] The invention relates to the technical field of rotary riveting equipment, in particular to a rotary riveting equipment for an inner tub of a washing machine. Background technique [0002] In the prior art, the riveting method used when riveting the upper and lower covers of the drum of the washing machine is: after flanging the inner cylinder and the upper and lower covers, the wheels with notches are rotated and rolled, and the two layers of materials are rotated and fastened, and then The disadvantages of this method are: the force is uneven during the pressing, resulting in uneven pressing, slow pressing speed and low efficiency, and the rotating flanges at the upper and lower ends of the inner cylinder Out of synchronization, resulting in dislocation and pressing of two pieces of material during riveting, affecting product quality. Contents of the invention [0003] Aiming at the shortcomings in the above-mentioned existing production technolog...
