Description

Technical Field

[0001] The utility model relates to an open rivet riveting device, belonging to the field of pin riveting tools. Background Art

[0002] Since many structural parts 11 are required to be able to rotate flexibly after assembly, such as door panels, in the design of assembly forms, many structural parts 11 with low strength requirements are often assembled using pins or rivets, which can not only enable the door panels 12 and structural parts 11 to rotate flexibly after assembly, but also facilitate and speed up installation. Pins are divided into solid pins and open rivets 15. The production costs of these two types of pins are different. When the demand for pins is very large, open rivets 15 with relatively low costs will be selected.

[0003] In the prior art, the open rivet 15 riveting device relies on manual visual inspection to align the pin hole and then press the open rivet 15 into the structural member 11 to connect the structural member 11 with the door panel 12. Due to the small size of the open rivet 15, it is inconvenient to operate during the riveting process, the visual inspection accuracy is not high, and the operation efficiency is low. In addition, manually pressing the open rivet 15 into the structural member 11 will cause arm soreness after working for a long time, and only one end of the rivet can be riveted at a time, which will also affect work efficiency.

[0030] Two guide shafts 8 are set on the upper pressure plate 3 and penetrate the top plate 2 to limit the axial rotation of the upper pressure plate 3. The lower pressure plate 6 is connected to the upper pressure plate 3 with an upper pin shaft 10 and an upper spring guide pin 4. The upper pressure plate 3 is restricted from axial rotation and the lower pressure plate 6 will not rotate either, thereby ensuring the accurate positioning of the upper rivet holes.

[0031] An upper spring 5 is arranged between the upper pressure plate 3 and the lower pressure plate 6, and a lower spring 21 is arranged between the bottom plate 7 and the base 14. After the open rivet 15 is pressed into the pin hole of the structural member 11, the upper pin shaft 10 and the lower pin shaft 13 are reset by the upper spring 5 and the lower spring 21 to prepare for the next riveting work.

[0032] The base 14 is connected to the bottom plate 7 via a lower spring guide pin 20, and a lower spring 21 is provided on the periphery of the lower spring guide pin 20 to fix the position of the bottom plate 7. The bottom plate 7 and the lower spring guide pin 20 are clearance-matched, so that the bottom plate 7 can move up and down; one end of the lower spring guide pin 20 is threadedly connected to the bottom plate 7, and the other end of the lower spring guide pin 20 is clearance-matched with the base 14, and can be extended and retracted up and down in the hole of the base 14.

[0033] The lower pin shaft 13 is fixed to the base 14 by the lower set screw 17. The lower pin shaft 13 and the bottom plate 7 are also clearance-fitted, so that the bottom plate 7 can move up and down while cooperating with the lower pin shaft 13. The lower pin shaft 13 is magnetic, and the open rivet 15 can be adsorbed on the end of the lower pin shaft 13 without falling off.

[0034] The upper pressure plate 3 and the lower pressure plate 6 are connected by an upper spring guide pin 4, and an upper spring 5 is provided on the periphery of the upper spring guide pin 4 to fix the position of the lower pressure plate 6. The upper pressure plate 3 and the upper spring guide pin 4 are clearance-matched, so that the lower pressure plate 6 can move up and down; one end of the upper spring guide pin 4 is threadedly connected to the lower pressure plate 6, and the other end of the upper spring guide pin 4 is clearance-matched with the upper pressure plate 3, and can be extended and retracted up and down in the hole of the upper pressure plate 3.

[0035] The upper pin shaft 10 is fixed on the upper pressure plate 3 by the upper set screw 9. The upper pin shaft 10 and the lower pressure plate 6 are clearance-matched, so that the lower pressure plate 6 can move up and down while cooperating with the upper pin shaft 10.

[0036] One end of the guide shaft 8 is fixed on the upper pressing plate 3, and the other end of the guide shaft 8 is clearance-fitted with the top plate 2, so that the upper pressing plate 3 can move up and down while limiting the axial rotation of the upper pressing plate 3.

[0037] The limit block 16 is fixed on the base 14 by axial cooperation. The distance between the upper end surface of the limit block 16 and the lower end surface of the bottom plate 7 is the length of the open rivet 15, which stops the up and down movement of the open rivet 15 after being pressed into the structural member 11, thereby limiting the up and down movement distance of the bottom plate 7 and the upper pressure plate 3 and preventing the upper pin shaft 10 and the lower pin shaft 13 from being crushed due to excessive force.

[0038] The upper pressure plate 3 is connected to the piston rod of the cylinder 1 through a thread to control the upper pressure plate 3 to move up and down. The lower end surface of the lower pressure plate 6 is in direct contact with the structural member 11. After pressure is applied to the contact surface of the structural member 11, the structural member 11 and the bottom plate 7 move downward together; the upper pressure plate 3 is connected to the piston rod of the cylinder 1 through a thread. The upper pressure plate 3 is connected to the lower pressure plate 6 through four upper spring guide pins 4 and can move up and down with the piston rod of the cylinder 1.

[0039] Specifically, the working process of the open rivet riveting device is as follows: First, the open rivet 15 is placed in the pin holes of the bottom plate 7 and the lower pressure plate 6 respectively, wherein the upper pin shaft 10 in the lower pressure plate 6 is magnetic, and the open rivet 15 can be adsorbed in the pin hole of the lower pressure plate 6 without falling off; second, the structural member 11 and the door panel 12 are placed on the bottom plate 7 together, and there are three positioning columns 19 on the bottom plate 7 that cooperate with the three positioning holes on the structural member 11 for precise positioning, and the right hand holds the structural member 11 and the door panel 12 to prepare for riveting assembly; third, the start switch controls the movement of the piston rod of the cylinder 1, and the piston rod of the cylinder 1 drives the upper pressure plate 3 to start moving downward. After the lower pressure plate 6 contacts the upper surface of the structural member 11, the structural member 11 and the door panel are assembled. 12 and the bottom plate 7 continue to move downward with the upper pressure plate 3. At this time, the upper and lower open rivets 15 begin to be pressed into the rivet holes of the structural member 11 and the door panel 12 under the pressure of the upper pin shaft 10 and the lower pin shaft 13. Under the pressure, the opening of the open rivet 15 will gradually shrink, and finally be smoothly pressed into the rivet holes of the structural member 11 and the door panel 12; the fourth step is to turn off the cylinder 1 switch, and the piston rod of the cylinder 1 begins to lift up. The bottom plate 7 and the lower pressure plate 6 also begin to rebound under the action of the lower spring 21 and the upper spring 5, respectively, and respectively drive the lower pin shaft 13 and the upper pin shaft 10 to retract and return to their positions, preparing for the next riveting work; the fifth step is to take out the structural member 11 and the door panel 12, and place and rivet the next structural member 11 and door panel 12.
