As a commonly used connection structure, riveting has the advantages of simple process and easy operation, and can realize the permanent connection between more than two parts. Therefore, it has a relatively wide application in connection structures.

[0003] In many cases, there are multiple riveting points on the same plane of the workpiece whose centers are located on the same straight line. For example, in order to improve the connection firmness, side riveting points are respectively arranged on both sides of the central riveting point to form a linear three-point riveting. During actual three-point riveting, it is necessary to move the riveting points to be riveted on the workpiece under the riveting head for riveting. The existing method is generally to manually move the workpiece by hand. This method has a long alignment time and there will be deviation, resulting in a decrease in riveting quality. Or, according to the number of riveting points, a corresponding number of riveting devices are configured, and the workpiece is moved to the riveting device corresponding to each point every time a point is riveted. Although this method can improve the riveting accuracy, three riveting devices are required for three-point riveting, the cost is relatively high, and the frequent transfer of the workpiece takes a long time, and the riveting efficiency is low.

First positioning grooves corresponding to the multiple riveting points one by one are arranged at intervals on the platform along the moving direction of the sliding seat. A positioning hole is vertically arranged on the sliding seat, and a positioning column is slidably connected in the positioning hole. When the positioning column is inserted into any first positioning groove, the riveting point corresponding to this first positioning groove is located directly below the riveting head.

[0006] A further improvement of the present utility model is that spherical segment-shaped grooves corresponding one by one to a plurality of riveting points are arranged at intervals along the moving direction of the slide on the platform.

An elastic member is arranged between the positioning steel ball and the bottom of the second positioning groove, and the positioning steel ball partially penetrates out of the second positioning groove through the elastic member and abuts against the spherical segment-shaped groove. When the positioning steel ball abuts in any spherical segment-shaped groove, the riveting point corresponding to the spherical segment-shaped groove is located directly below the riveting head.

[0007] A further improvement of the present utility model is that the height of the spherical segment-shaped groove is less than its radius.

[0008] A further improvement of the present utility model is that there are three riveting points, which are arranged on the same plane of the workpiece, and the centers of the three riveting points are located on the same straight line.

[0009] A further improvement of the present utility model is that the length of the positioning post is greater than the sum of the thickness of the slide and the depth of the first positioning groove.
