Description

Technical Field

[0001] The invention relates to the technical field of feeding equipment, and in particular to a feeding rivet nut tool. Background Art

[0002] At present, the assembly of rivet nuts mostly uses manual handheld rivet guns, which requires high labor intensity. Hands are prone to soreness from holding the rivet gun for a long time. With repetitive work, eyes are also easily fatigued, and it is easy to rivet the wrong position and it is extremely dangerous. At the same time, it takes a lot of time and manpower to rivet workpieces in batches, which makes the manpower tired, low processing efficiency and high cost. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a loading rivet nut tool to assist manual riveting of workpieces, reduce labor intensity, save time and effort, and improve work efficiency in response to the deficiencies of the above-mentioned prior art.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a loading rivet nut tooling, comprising a frame, the frame being provided with a loading device for conveying rivet nuts and workpieces to be riveted, the loading device being linked with a rivet device arranged on the upper part of the frame, characterized in that: the frame is detachably connected to a first mounting plate relative to an end away from the ground, the first mounting plate being detachably connected to a plurality of groups of rivet guns, the frame being fixed with a workpiece conveying plate and a rivet nut conveying rail in sequence toward the ground with one end connected to the first mounting plate as a starting point, the workpiece conveying plate being provided with a long avoidance groove corresponding to the position of the rivet gun, the loading device comprising a rivet nut conveying assembly slidably connected to the rivet nut conveying rail, the rivet nut conveying assembly comprising a second mounting plate for placing a plurality of groups of rivet nuts, the second mounting plate being provided with a plurality of groups of rivet nut placement holes corresponding to the end surface of the rivet gun, and the frame being located at an end of the rivet nut conveying rail close to the ground and provided with a lifting assembly that can be intermittently linked with the second mounting plate.

[0005] By adopting the above technical solution, mechanical riveting can be achieved by setting up three modules: a machine frame, a loading device, and a rivet device, which replaces manual riveting, reduces labor intensity, and improves work efficiency; the machine frame is used to carry various components, and when conveying the rivet nut, it is only necessary to place the rivet nut in the rivet nut placement hole on the second mounting plate, and then move the second mounting plate to the corresponding position of the rivet gun through the rivet nut conveying track. The workpiece to be riveted can be moved to the corresponding position of the rivet gun through the workpiece conveying plate, wherein the workpiece conveying plate is provided with a avoidance groove at the rivet gun position to allow the rivet nut to enter the workpiece through the workpiece conveying plate. After the workpiece is conveyed, the lifting device is used to push the second mounting plate upward so that the rivet nut is passed through the workpiece, and finally the rivet gun is started to complete the riveting, which can realize mechanical riveting of each rivet nut, reduce labor intensity, and save time and effort by setting multiple groups of rivet guns, thereby improving work efficiency.

[0006] The above technical solution can be further configured as follows: the lifting assembly includes a cylinder, the cylinder is linked to a push rod, the push rod is intermittently linked to the second mounting plate, and the push rod is provided with a guide column at the other end relative to the linked cylinder, the outer diameter of the guide column is smaller than the outer diameter of the push rod and is integrally formed with the push rod.

[0007] The above technical solution can be further configured as follows: the second mounting plate is provided with a guide hole which can be clearance-matched with the push rod guide column on the other end face relative to the rivet nut placement hole.

[0008] By adopting the above technical solution, a guide column is set at the end of the push rod, and the guide column cooperates with the guide hole on the second mounting plate to guide and position the push rod. The guide column and the guide hole have an interference fit. The purpose is that when the riveting is completed, the cylinder pulls the push rod down, and the guide column can be smoothly disengaged from the guide hole, and no downward pulling force will be generated on the second mounting plate, thereby preventing the second mounting plate from falling off the rivet nut conveying track, thereby further playing a safety protection role.

[0009] The above technical solution can be further configured as follows: the rivet nut conveying assembly further includes rollers, and the rollers are symmetrically and movably hinged at both ends of the second mounting plate.

[0010] By adopting the above technical solution, the second mounting plate is detachably connected to the rivet nut conveying track through the roller. The roller and the rivet nut conveying track are in point contact, with small friction. The second mounting plate moves smoothly on the rivet nut conveying track, further improving the performance.

[0011] The above technical solution can be further configured as follows: a push rod is fixedly provided on one side of the second mounting plate.

[0012] By adopting the above technical solution, a push rod is set on one side of the second mounting plate to facilitate manual pulling of the second mounting plate.

[0013] The above technical solution can be further configured as follows: a first limiting rod is provided at the end of the workpiece conveying plate.

[0014] By adopting the above technical solution, the first limit rod can be set to facilitate the positioning of the workpiece on the frame, so as to facilitate the corresponding positions of the workpiece and the rivet gun; since the sizes of the workpieces are mostly uniformly fixed, and the position for installing the rivet nut also has specific sizes, the position of the first limit rod at the end of the workpiece conveying plate can be selected according to actual conditions to correspond to workpieces of different sizes, which can improve adaptability.

[0015] The above technical solution can be further configured as follows: a second limiting rod is provided at the end of the rivet nut conveying track.

[0016] By adopting the above technical solution, the second mounting plate can be easily positioned on the frame by providing the second limiting rod, so as to facilitate the corresponding positions of the rivet nut, the workpiece and the rivet gun.

[0017] The beneficial effects of the present invention are as follows: by adopting the above technical scheme, mechanical riveting can be achieved by setting up three modules of a frame, a loading device, and a rivet device, replacing manual riveting, reducing labor intensity, and improving work efficiency; by setting a guide column at the end of the push rod, the guide column cooperates with the guide hole on the second mounting plate, which plays a guiding and positioning role for the push rod, and at the same time plays a role of safety protection; further arranging rollers on both sides of the second mounting plate can reduce friction, promote the second mounting plate to move smoothly on the rivet nut conveying track, and further improve the performance of use; by setting the first limit rod and the second limit rod, the workpiece and the second mounting plate can be easily positioned on the frame, so as to facilitate the corresponding positions of the workpiece, the rivet gun and the like.
