Description

Technical Field

[0001] The utility model relates to the technical field of riveting equipment, in particular to a multi-stage suspended riveting equipment with a fixing function. Background Art

[0002] In sheet metal processing, a riveting machine is usually used to rivet sheet metal parts. During riveting, the riveted material is plastically deformed by pressure and squeezed into the specially designed riveting holes in the sheet, thereby achieving a reliable connection between the two parts.

[0003] In the early technology, when the riveting process is performed on the workpieces that need to be riveted, it is usually completed manually or with the help of some auxiliary equipment, which has low production efficiency, high labor intensity, and the processing quality cannot be guaranteed. In addition, there are certain safety hazards in the production process. Therefore, there is a public technology that provides a multi-stage suspended riveting device to solve the above problems, which includes a base, a support column and a first motor. The support column is arranged on the right side of the upper surface of the base, and the first motor is arranged on the top of the support column. The shaft of the first motor is connected to the screw rod, and the top of the screw rod extends to the inner cavity of the support column and is rotatably connected to the support column through a bearing. The screw rod is rotatably connected with a threaded sleeve, and a movable plate is arranged on the left side of the threaded sleeve. The left end of the movable plate extends to the outside of the support column. When in use, the workpiece is placed in the groove. Under the action of the spring, the two fixed blocks are relatively moved, so that the workpiece is squeezed and fixed to prevent the workpiece from popping out and causing harm to the human body during the work process. The first motor is started to rotate the screw rod, so that the movable plate moves downward, so that the limit plate contacts the upper surface of the base, and the two limit plates are respectively located on both sides of the groove;

[0004] However, there are obvious drawbacks in the use of the above-mentioned public technology.

Moreover, most of the parts to be riveted are usually two iron sheet types, and the shapes of the parts are various. The above-mentioned technology cannot be applied. Therefore, it is necessary to optimize and improve the structure of the multi-stage suspended riveting equipment. Utility Model Content
