Description

TECHNICAL FIELD

[0001] The utility model relates to the field of metal processing, more particularly to a riveting equipment. BACKGROUND

[0002] When producing and manufacturing automobile parts, various riveting parts (such as rivets, nuts, etc.) need to be pre-riveted at the design position according to the requirements of the host factory, and the riveting machine is the basic equipment for riveting work. In the early days, the riveting process of automobile parts used manual feeding and discharging, and workers held workpieces close to the working position of the automatic riveting machine for riveting. At present, with the wide application of industrial robots, the process of workers holding workpieces has been gradually replaced by mechanical hands; however, the mechanical hand needs to define a relatively closed riveting station to ensure safe production.

[0003] In addition to the lifting and riveting action, the automatic riveting machine is kept in a relatively fixed state with the installation base (foundation), and whether manual feeding and discharging or mechanical hand feeding and discharging is used, the operator needs to actively approach the automatic riveting machine at the riveting position of the workpiece. Due to the large operation radius of the mechanical hand for taking and delivering workpieces, and the need for a supporting discharging chain conveyor, the riveting station occupies a large area; at the same time, the current mechanical hand operation also has the problems of slow rhythm and low production efficiency. INVENTION CONTENTS

[0004] In order to reduce the area occupied by the riveting station and improve the efficiency of riveting work, the utility model provides a system capable of actively approaching the riveting position of the workpiece, and the main technical scheme is as follows:

[0005] A gantry type riveting system, the key of which is that it comprises a base, a portal and a workpiece clamping assembly are arranged on the base; the portal comprises mutually parallel middle and top cross beams, the middle and top cross beams are located above the base, the top cross beam is located directly above the middle cross beam, a riveting base is slidably assembled on the middle cross beam along the length direction thereof, an automatic riveting machine is slidably assembled on the top cross beam along the length direction thereof, the riveting base is located directly below the automatic riveting machine, and the riveting base and the automatic riveting machine slide synchronously; the workpiece clamping assembly is slidably assembled on the base, the workpiece clamping assembly slides to approach or move away from the portal, and the clamping part of the workpiece clamping assembly can extend into the middle cross beam and the top cross beam.

[0006] The technical solution of this utility model integrates workpiece feeding and unloading with automatic riveting. The workpiece clamping assembly moves the workpiece from the first horizontal direction to the automatic riveting machine, while the automatic riveting machine actively searches for different riveting positions on the workpiece from the second horizontal direction. This allows for faster alignment and riveting of different riveting positions on the workpiece with the automatic riveting machine, accelerating the production cycle and improving production efficiency. Simultaneously, it avoids the need for robotic arms for feeding and unloading, reducing the required operating area. Attached Figure Description
