Abstract
The utility model discloses a special spin riveting head structure matched with an automatic spin riveting machine. The special spin riveting head structure matched with the automatic spin riveting machine comprises a spin riveting head, a three-step groove is formed on the end face of the spin riveting head, a prepressing rotating head and a compression spring are connected in the three-step groove from outside to inside, a two-step through hole is formed in the prepressing rotating head, a regulating screw inserts into the two-step through hole and passes through the compression spring and is screwed to connected with the three-step groove, and a screw head and a screw rod of the regulating screw are matched with the two-step through hole. According to the special spin riveting head structure matched with the automatic spin riveting machine, the compression spring and the prepressing rotating head capable of rotating flexibly are arranged inside the spin riveting head, so that the prepressing rotating head is pressed in advance on a part anchor which cooperates with the prepressing rotating head in riveting process, and the spin riveting head is also pressed tightly to cooperate with a part. Good positioning for the cooperated parts is achieved, displacement changes between cooperated parts in the riveting process are avoided, and an assembly after riveting is guaranteed to be qualified.
Description
Technical field
The utility model relates to the matching used Special rotary die of a kind of automatic riveter structure, belongs to the riveter equipment technical field.
Background technology
Riveting machine (also being referred to as rivet driver, riveter, lock seaming machine, rolling riveter etc.) is a kind of novel riveting equipment developed according to cold rolling principle, just refers to and can rivet mechanized equipment to article with rivet.Riveting machine mainly completes assembling by rotation and pressure, common are pneumatic, oil pressure and electronic, single head and double end equal-specification model.
Riveter cold roll riveting, utilize rivet rod to swing continuously until the clinching method that rivet is shaped rivet pressurized ，Bing Rao center exactly.Have now when using accurate automatic riveter riveted joint workpiece, general only for centre cylinder not with holes carry out outside expansion deformation riveted joint, and the assembly of combining for a plurality of parts carries out circumference flange distortion riveted joint, because there is no fixture preferably, never have the fixation problem that a good way solves relative position between mating parts, assembly is easily occurrence positions change in the riveted joint process, causes the later workpiece size of riveted joint defective.
In riveted joint small volume part riveted joint process, due to the inside parts narrow space, riveted joint is in swinging the process of being riveted continuously simultaneously, and riveted joint is easy to hurt by riveted joint thing parts.
Summary of the invention
The technical problems to be solved in the utility model is, provide a kind of simple in structure, workpiece can not be subject to the riveted joint damage, have the matching used Special rotary die of the automatic riveter structure of positioning function, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: the matching used Special rotary die of automatic riveter structure, it comprises revolves die, be processed with the syllogic stepped recesses at the end face that revolves die, be connected with from outside to inside precompressed swivel head and Compress Spring on the syllogic stepped recesses, offer the two-part step through-hole on the precompressed swivel head, the two-part step through-hole of adjustment screw from the precompressed swivel head inserts, is screwed on the syllogic stepped recesses through after Compress Spring, and the head of screw of adjustment screw coordinates with the two-part step through-hole respectively with shank of screw.
Be processed with the inner bevel α of 3～7 ° in the outer face of revolving die.
The end face of precompressed swivel head is circular arc
Compared with the prior art, but the utility model is installed the precompressed swivel head of a Compress Spring and flexible rotating in the inside of revolving die, can in the riveted joint process, be pressed in advance on the part anchor point cooperatively interacted by the precompressed swivel head like this, make and revolve in the process that die swings also compression fit part, can well to the part that cooperatively interacts, play positioning action, prevent from being subjected to displacement variation between mating parts in the riveted joint process, guarantee to rivet later assembly quality qualified.The precompressed swivel head utilizes spring and adjustment screw to be fixed, and this structure can change the pressure of precompressed swivel head by the rotation of adjustment screw, can meet so the different precompressed demands of riveted joint assembly.Be processed with the inner bevel α of 3～7 ° in the outer face of revolving die, can compensate like this work drift angle of automatic riveter itself, meet the riveted joint workpiece when peripheral space is narrower and small and do not sustain damage.The end face of precompressed swivel head, for adopting circular arc, so conveniently positions mating parts.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The B section enlarged drawing that Fig. 2 is Fig. 1.
The specific embodiment
Embodiment 1: as depicted in figs. 1 and 2, revolving die 1 is connected on riveting machine, its specification can be changed according to riveted requirement, be processed with syllogic stepped recesses 6 at the end face that revolves die 1, be connected with from outside to inside precompressed swivel head 4 and Compress Spring 2 on syllogic stepped recesses 6, offer two-part step through-hole 5 on precompressed swivel head 4, the two-part step through-hole 5 of adjustment screw 3 from precompressed swivel head 4 inserts, on the syllogic stepped recesses 6 that spins after Compress Spring 2, the head of screw of adjustment screw 3 coordinates with two-part step through-hole 5 respectively with shank of screw, this structure can make precompressed swivel head 4 flexible rotatings and have the function of the flexible application of force downwards, to adapt to the different precompressed demands of various assembly machines.
Be processed with the inner bevel α of 3～7 ° in the outer face of revolving die 1.Oblique angle can compensate the work drift angle of automatic riveter itself, meets the riveted joint workpiece when peripheral space is narrower and small and does not sustain damage.The end face of precompressed swivel head 4 is circular arc, so conveniently mating parts is positioned.
