[0001] This utility model relates to the field of quick-change device technology, specifically a quick-change device for rivet guns and tightening guns. Background Technology

[0002] In aerospace, automotive manufacturing, and steel structure assembly, rivet guns and tightening guns are two core tools. In traditional operations, operators need to frequently change tools according to process requirements, which results in inconsistency in operation and greatly reduces work efficiency. In addition, manual installation is prone to errors, such as poor sealing of pneumatic pipelines leading to pressure leakage, or misalignment of electrical contacts causing signal transmission interruption, which in turn affects the riveting strength or torque accuracy. Furthermore, rivet guns are relatively heavy, usually weighing 30kg-70kg, and the rigidity of traditional quick-change mechanisms is insufficient to meet the needs of high-efficiency production.

[0016] like Figures 1-8 As shown: A quick-change device for rivet guns and tightening guns includes a quick-change assembly 1 and matching rivet gun docking stations 2 and tightening gun docking stations 3. The quick-change assembly 1 includes a detachably connected gun-changing disc male end 101 and a gun-changing disc female end 102. A connecting protrusion 1011 is provided at the middle position of the gun-changing disc male end 101. A plurality of steel balls 1013 and an air intake assembly for driving the steel balls 1013 to slide out of the connecting protrusion 1011 are slidably installed in the connecting protrusion 1011. A connecting groove 1021 is provided at the middle position of the gun-changing disc female end 102. A limit switch 1024 is provided on one side of the gun-changing disc female end 102. A plurality of steel ball slots 1022 are provided in the connecting groove 1021. A plurality of positioning posts 1012 are also provided on the gun-changing disc male end 101, and a plurality of positioning holes 1023 matching the positioning posts 1012 are provided on the gun-changing disc female end 102.

[0017] In this embodiment, the limit switch 1024 is used to detect the position of the female end 102 of the gun changing disc.

[0018] The dimensions of the connecting protrusion 1011 and the connecting groove 1021 are matched, the number of steel balls 1013 is the same as the number of steel ball slots 1022, and the dimensions of the steel balls 1013 are matched with the dimensions of the steel ball slots 1022.

[0019] In this embodiment, one side of the gun-changing disc male end 101 is detachably connected to the robotic arm, and the robotic arm drives the quick-change assembly 1 to perform operations.

[0020] When it is necessary to connect the male end 101 and the female end 102 of the gun changer, the robotic arm first aligns the connecting protrusion 1011 on the male end 101 with the connecting groove 1021, aligns the positioning pin 1012 with the positioning hole 1023, and then inserts the connecting protrusion 1011 into the connecting groove 1021 and the positioning pin 1012 into the positioning hole 1023, thus achieving the initial connection between the male end 101 and the female end 102 of the gun changer. Then, the air intake assembly of the male end 101 of the gun changer is activated, and the steel ball 1013 in the connecting protrusion 1011 slides outward under the push of the air intake assembly and is locked in the steel ball slot 1022, thereby achieving the connection between the male end 101 and the female end 102 of the gun changer, which is convenient for use.

[0021] When it is necessary to separate the male end 101 and the female end 102 of the gun changer, first shut off the air intake assembly. After the steel ball 1013 loses the air passage propulsion, it slides into the connecting protrusion 1011. Then, the robotic arm pulls the male end 101 of the gun changer out of the female end 102 of the gun changer for easy use.

[0022] Both the male end 101 and the female end 102 of the gun changing disc are provided with several power connection devices 103 on their sides.

[0023] In this embodiment, the power connection device 103 can be used to make an electrical connection with a riveting tool or a tightening tool, or to make an electrical connection with an air intake assembly.

[0024] The bottom surface of the female end 102 of the gun changing disc is detachably connected to a rivet gun connecting flange 1025, and a rivet gun 4 is detachably connected to the rivet gun connecting flange 1025.

[0025] In this embodiment, the female end 102 of the rivet gun changing disc is connected to the rivet gun connecting flange 1025 by bolts, and the rivet gun connecting flange 1025 is also connected to the rivet gun 4 by bolts.

[0026] The rivet gun docking station 2 includes a rivet gun docking station base 201. The upper surface of the rivet gun docking station base 201 is provided with a plurality of rivet gun guide posts 202 and a plurality of rivet gun positioning pins 203. A limit plate 204 is provided on the rivet gun positioning pins 203.

[0027] The rivet gun docking station base 201 is also provided with a first bracket 206, and a first cylinder 207 is provided on the first bracket 206. The power output end of the first cylinder 207 is connected to the first gun changing disc protective cover group 208.

[0028] In use, the rivet gun guide post 202 is used to guide and limit the rivet gun 4, the rivet gun positioning pin 203 is used to limit and fix the rivet gun 4, and the first cylinder 207 is used to drive the first gun changing disc protective cover group 208 to rotate, thereby realizing the protection of the female end 102 of the gun changing disc.

[0029] The lower bottom surface of the female end 102 of the gun changing disc is detachably connected to a tightening gun connecting flange 1026, and a tightening gun 5 is detachably connected to the tightening gun connecting flange 1026.

[0030] The tightening gun docking station 3 includes a tightening gun docking base 301, on which a limit block 302 and a tightening gun positioning pin 303 are provided. A second cylinder 304 is also fixedly installed on one side of the tightening gun docking station 3. The power output end of the second cylinder 304 is connected to a second gun changing disc protective cover 305.

[0031] In this embodiment, the second gun-changing disc protective cover 305 is used to protect the female end 102 of the gun-changing disc carrying the tightening gun 5.

[0032] In use, both the rivet gun 4 and the tightening gun 5 are detachably connected to their corresponding gun-changing disc female ends 102, i.e., there are at least two gun-changing disc female ends 102. The detachable connection between the gun-changing disc male end 101 and the gun-changing disc female end 102 is achieved by locking and releasing the steel balls 1013 and steel ball slots 1022 in the gun-changing disc male end 101 and the gun-changing disc female end 102. After the rivet gun 4 is used up, the gun-changing disc male end 101 and the gun-changing disc female end 102 are separated. The gun-changing disc female end 102 carrying the rivet gun 4 is placed in the rivet gun docking station 2. Then, the robotic arm drives the gun-changing disc male end 101 to engage with the gun-changing disc female end 102 carrying the tightening gun 5, and the tightening gun 5 is removed from the tightening gun docking station 3 for tightening operation, which is convenient to use.

[0033] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
