Shell riveting device

Abstract

The invention discloses a shell riveting device. The shell riveting device comprises a machine frame, a shell four-corner inner supporting mechanism and a shell riveting mechanism. The shell four-corner inner supporting mechanism and the shell riveting mechanism are installed on the machine frame. The shell four-corner inner supporting mechanism is used for supporting a shell when the shell is riveted. The shell four-corner inner supporting mechanism comprises four vertically-arranged inner supporting columns used for supporting the four corners of the shell. The shell riveting mechanism is used for riveting the shell and comprises two symmetrical and vertically-arranged outer supporting frames, two symmetrical and vertically-arranged inner supporting frames, two shell attachment adjustment mechanisms, plate type slide rails and a double-stroke oil cylinder. Riveting bases are arranged inside the outer supporting frames. Riveting heads are arranged outside the inner supporting frames. The outer supporting frames and the inner supporting frames are erected on the plate type slide rails. The shell attachment adjustment mechanism is connected with the outer supporting frames and used for driving the outer supporting frames to move along the plate type slide rails so that the riveting bases can get close to the outer side of the shell. The double-stroke oil cylinder is arranged between the two inner supporting frames and provides impact force for shell riveting.

Description

technical field [0001] The invention relates to shell riveting equipment. Background technique [0002] Refrigerator casings are made of sheet metal. The stepped refrigerator shell is made of two parts that are molded independently and spliced ​​together. The splicing of the two parts finally needs to be done by riveting. When riveting the preliminarily formed refrigerator shell, in order to keep the shape of the shell unchanged, it needs to be supported inside. Ordinary internal mold support mechanism will occupy the interior of the refrigerator shell and cannot be aligned for riveting processing. For this reason, a special internal support mechanism that does not occupy the internal space of the refrigerator shell is required. On the other hand, when the shell is riveted, the riveting is usually located inside the shell. When using an ordinary oil cylinder to provide impact force for the riveting, the volume of the ordinary oil cylinder is too large, and the impact stro...

Ordinary internal mold support mechanism will occupy the interior of the refrigerator shell, and cannot be aligned for riveting processing. For this reason, a special internal support mechanism that does not occupy the internal space of the refrigerator shell is required

On the other hand, when the shell is riveted, the riveting is usually located inside the shell. When using an ordinary oil cylinder to provide impact force for the riveting, the volume of the ordinary oil cylinder is too large, and the impact stroke is relatively insufficient.
