[0055] The receiving assembly 3 is connected to a feeding device for a kind of rivets, and this device can convey the rivets to the receiving assembly 3.

[0056] The trigger assembly 2 and the receiving assembly 3 are provided on the rivet gun body 1, and the rivet gun body 1 includes: a riveting head 11, and the riveting head 11 is used for fixing the rivets.

[0057] The trigger assembly 2 is used to make the receiving assembly 3 in a closed state during the riveting process and in a separated state after the riveting ends.

[0058] In the closed state, the receiving assembly 3 is configured to insert the rivets conveyed by the feeding device into the riveting head 11. In the separated state, the riveting head 11 can pass through the receiving assembly 3.

[0059] During the riveting process, the triggering assembly 2 causes the receiving assembly 3 to enter the closed state. The receiving assembly 3 in the closed state can insert the rivets onto the riveting head 11. After the riveting is completed, the triggering assembly 2 causes the receiving assembly 3 to enter the separated state, and the riveting head 11 can pass through the receiving assembly 3 in the separated state to perform the riveting work, significantly improving the riveting efficiency throughout the process.

[0060] As Figures 1 to 7 shown, the triggering assembly 2 includes: a driving member 21 and a sliding mechanism. Both the sliding mechanism and the driving member 21 are fixed on the rivet gun body 1. The driving member 21 is configured to drive the receiving assembly 3 to move on the sliding mechanism.

The sliding member 23 is slidably disposed on the slide rail 22, and the receiving assembly 3 is disposed on the sliding member 23.

[0061] By driving the sliding member 23 to move on the slide rail 22 through the driving member 21, the receiving assembly 3 is driven to move, providing the power for the receiving assembly 3 to switch from the closed state to the separated state, and enabling the rivet gun head to pass through the receiving assembly 3.

[0062] In this embodiment, the driving member 21 can be a cylinder, a hydraulic cylinder or a motor, as long as it can drive the receiving assembly 3 to move.

[0063] As Figures 1 to 7 shown, the receiving assembly 3 includes: a first separation plate 42, a second separation plate 43 and a connecting plate 41. The connecting plate 41 is fixed on the sliding member 23. The first separation plate 42 and the second separation plate 43 are oppositely arranged on the connecting plate 41 and are both rotatably connected to the connecting plate 41.

[0064] When the receiving assembly 3 changes from the separated state to the closed state, the first separation plate 42 and the second separation plate 43 approach each other. When the receiving assembly 3 changes from the closed state to the separated state, the first separation plate 42 and the second separation plate 43 move away from each other, and the opening formed by the mutual separation can allow the rivet head to pass through.

[0065] When the receiving component 3 changes from the separated state to the closed state, both the first separation plate 42 and the second separation plate 43 rotate, causing the first separation plate 42 and the second separation plate 43 to approach each other. When the receiving component 3 changes from the closed state to the separated state, driven by the triggering component 2, both the first separation plate 42 and the second separation plate 43 rotate, causing the first separation plate 42 and the second separation plate 43 to move away from each other, and the opening generated by the mutual separation allows the rivet head to pass through, enabling the rivet head to perform the riveting work.

[0066] As Figures 9 to 12 shown, the triggering component 2 includes: a separating plug plate 5; the receiving component 3 further includes: a first pulley 44 and a second pulley 45.

[0067] The first pulley 44 is provided on the first separation plate 42, the second pulley 45 is provided on the second separation plate 43, and the first pulley 44 and the second pulley 45 are arranged oppositely. When the separating plug plate 5 is inserted between the first pulley 44 and the second pulley 45, it triggers the first separation plate 42 and the second separation plate 43 to move away from each other, causing the receiving component 3 to enter the separated state.

[0068] When the separating plug plate 5 is withdrawn from between the first pulley 44 and the second pulley 45, it triggers the first separation plate 42 and the second separation plate 43 to approach each other, causing the receiving component 3 to enter the closed state.

[0069] During the process of the triggering component 2 driving the receiving component 3 to move, the first pulley 44 and the second pulley 45 come into contact with the separating plug plate 5, and the separating plug plate 5 will be inserted between the first pulley 44 and the second pulley 45, causing the first separation plate 42 and the second separation plate 43 to rotate in opposite directions, thereby causing the first separation plate 42 and the second separation plate 43 to separate from each other, and the receiving component 3 enters the separated state.

[0070] As Figures 9 to 12 shown, the separating plug plate 5 includes: a plate body, a reduced-diameter portion, and a top insertion portion. The plate body is connected to the rivet gun body 1, the reduced-diameter portion has a large-diameter end and a small-diameter end, the large-diameter end is connected to the plate body, and the small-diameter end is connected to the top insertion portion.

[0071] The top insertion portion of the separating plug plate 5 can be smoothly inserted between the first pulley 44 and the second pulley 45, and the first separation plate 42 and the second separation plate 43 are gradually pushed open through the reduced-diameter portion, causing the first separation plate 42 and the second separation plate 43 to separate from each other.

[0072] As Figures 8 to 12 shown, the receiving component 3 further includes: a reset mechanism. The reset mechanism is used to provide the power to trigger the first separation plate 42 and the second separation plate 43 to approach each other.

[0073] In this embodiment, the reset mechanism is arranged at the rotational connection between the first separation plate 42 and the connection plate 41, and at the rotational connection between the second separation plate 43 and the connection plate 41. The reset mechanism can be a circlip pin, a spiral spring or a spring, as long as it can provide the power for the first separation plate 42 and the second separation plate 43 to approach each other.

[0074] As Figures 8 to 12 shown, the receiving assembly 3 further includes: a receiving portion 31 and a riveting portion 32. The receiving portion 31 includes: a receiving tube 312 and a connection block 311.

[0075] The receiving tube 312 is arranged on the connection block 311. The receiving tube 312 communicates with the feeding device. A material leakage opening 313 is formed on the receiving tube 312. The material leakage opening 313 is set corresponding to the size of the rivet. The connection block 311 is connected to the first separation plate 42.

[0076] The riveting portion 32 is connected to the second separation plate 43. A material groove 321 is arranged on the riveting portion 32. The material groove 321 corresponds to the material leakage opening 313 of the receiving tube 312. A material clamping opening 322 is formed at one end of the material groove 321. The diameter of the material clamping opening 322 is smaller than the cross-sectional diameter of the rivet.

[0077] The rivets conveyed by the feeding device first enter the receiving tube 312. The rivets fall into the material groove 321 of the riveting portion 32 through the material leakage opening 313. The material clamping opening 322 can clamp the round cap of the rivet to prevent the rivet from being misaligned during the rivet feeding process. During the process of driving the receiving assembly 3 to move by the triggering assembly 2, the material clamping opening 322 can provide a thrust to insert the rivet into the riveting head 11.

[0078] As Figures 1 to 4 shown, the rivets enter the receiving tube 312 but do not pass through the material leakage opening 313. As Figures 5 to 7 shown, the state where the rivets are inserted into the rivet head.

[0079] As Figures 1 to 7 shown, the receiving assembly 3 includes: a first separation plate 42, a second separation plate 43 and a connection plate 41. The first separation plate 42 and the second separation plate 43 are oppositely arranged on the connection plate 41 and are both rotationally connected to the connection plate 41. When the receiving assembly 3 changes from the separated state to the closed state, the first separation plate 42 and the second separation plate 43 approach each other. When the receiving assembly 3 changes from the closed state to the separated state, the first separation plate 42 and the second separation plate 43 move away from each other, and the opening formed by the mutual separation can allow the rivet head to pass through.

[0080] As Figures 1 to 12As shown, the rivet gun further includes a monitoring mechanism and a control system. The monitoring mechanism is disposed on the receiving assembly 3, and the control system starts the riveting process when the monitoring mechanism detects a rivet.

[0081] Generally speaking, the present application provides a rivet gun. When the receiving assembly 3 is in the closed state, the rivets conveyed by the feeding device first enter the receiving tube 312, and the rivets fall into the material groove 321 of the riveting part 32 through the material leakage port 313, and the round cap of the rivet is clamped by the clamping port 322. The driving member 21 drives the receiving assembly 3 to move on the slide rail 22, so that the rivet is inserted into the riveting gun head. The separating plate 5 will be inserted between the first pulley 44 and the second pulley 45, and the first separating plate 42 and the second separating plate 43 are separated from each other, so that the receiving assembly 3 enters the separating state. At this time, the riveting joint 11 can pass through the receiving assembly 3 to perform the riveting work.

[0082] After the riveting is completed, the driving member 21 drives the receiving assembly 3 to move, withdraws the riveting joint 11 from between the first separating plate 42 and the second separating plate 43, and drives the first separating plate 42 and the second separating plate 43 to approach each other through the reset mechanism, so that the receiving assembly 3 is in the closed state.
