DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 A new type of universal riveting machine in this embodiment includes a base 1, a lower support block 2 is fixedly installed on the top of the base 1, a back plate 3 is fixedly connected to the back of the lower support block 2, an upper support block 4 is fixedly installed on the front of the back plate 3 and located above the lower support block 2, an upper template 5 is fixedly installed below the upper support block 4, and a riveting assembly 6 is arranged between the upper template 5 and the base 1.

[0026] The riveting assembly 6 includes a cylinder 601 fixedly connected to the bottom of the upper template 5, the output shaft of the cylinder 601 is fixedly connected to the forming punch 602, a lower template 603 is arranged on the top of the base 1, and a pressing plate 604 is arranged on the top of the base 1 and on both sides of the lower template 603, and the two sides of the lower template 603 are slidably connected to the surface of the pressing plate 604, a forming block 605 is arranged on the top of the lower template 603, and a raised step 608 is provided on the forming block 605, and the spring piece can be accurately positioned by the step 608, and a positioning groove is provided on the top of the lower template 603, and the forming block 605 is fixed to the lower template 603 through the positioning groove, and the forming block 605 and the lower template 603 can be conveniently fixed by a screw through the positioning groove, and the positioning groove also plays a positioning function, which is convenient for coordinate positioning when the forming block 605 is installed, and the top wall of the forming block 605 is respectively provided with a placement groove 606, and an anti-rotation groove 607 is provided on the rear side of the upper end of the forming punch 602.

[0027] By placing the spring pieces and workpieces to be riveted on the forming block 605, the cylinder 601 drives the forming punch 602 to extend and retract, so that the forming punch 602 can rivet the spring pieces and the workpieces on the forming block 605. Since an anti-rotation groove 607 is provided on the rear side of the upper end of the forming punch 602, the forming punch 602 can be prevented from rotating during the riveting process to affect the riveting effect.
