Description

Technical Field

[0001] This utility model belongs to the field of riveting device technology, specifically relating to a pneumatic riveting device. Background Technology

[0002] The existing riveting device uses the movement of a cylinder to drive a special connecting riveting plate through an instantaneous high-pressure processing process, forming a component with a certain tensile and shear strength based on the cold extrusion deformation of the copper tube material itself; Existing riveting devices place the copper tube to be riveted directly on the surface of the riveting base plate during riveting operations. Then, the cylinder moves the riveting plate down to the surface of the riveting base plate for riveting. Therefore, during riveting operations, the force point of the riveting plate driven by the cylinder is in the middle position. Frequent riveting makes it difficult for the two ends to bear the force when the middle is under stress. In fact, the two ends of the riveting plate may even deform upwards. Frequent riveting can also cause the fixed bolts to loosen. This makes it easy to deform and loosen during frequent riveting, affecting the uniformity and reinforcement of the force on the riveting plate during riveting operations. To address this, this utility model proposes a pneumatic riveting device. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1 to 5 This utility model provides a technical solution: a pneumatic riveting device, including a riveting device body 100, the riveting device body 100 including a fixed base 101, a riveting base plate 102 fixedly installed on the upper surface of the fixed base 101 by fixing bolts, a column 104 fixed to the tail end of the upper surface of the fixed base 101 by fixing bolts, a fixed top plate 106 fixed to the top surface of the column 104, and a riveting pressure plate 103 provided on the lower surface of the fixed top plate 106; A cylinder 105 is bolted to the top of the fixed top plate 106, and the cylinder 105 is connected to an external air source and connected to a solenoid valve. The bottom end of the cylinder 105 is bolted to the middle of the upper surface of the riveting plate 103. A pneumatic switch 107 is provided on one side of the fixed base 101, and a controller is fixed on one side of the fixed top plate 106. The pneumatic switch 107, the solenoid valve, and the controller are electrically connected by wires. A copper tube is placed on the surface of the riveting base plate 102. Pressing the pneumatic switch 107 opens the solenoid valve through the controller. After the solenoid valve opens, it provides an external air source to the cylinder 105 to move. The cylinder 105 drives the riveting plate 103 to move down and rivet on the upper surface of the riveting base plate 102. The riveting device body 100 is also equipped with: The uniform force reinforcement mechanism includes a uniform force riveting assembly located at the connection between the bottom end of the cylinder 105 and the surface end of the riveting plate 103. Auxiliary reinforcement assemblies are provided on both sides of the lower surface of the uniform force riveting assembly. When the riveting device body 100 is in use, the uniform force reinforcement mechanism can effectively rivet the riveting plate 103 uniformly when the cylinder 105 drives the riveting plate 103 to move down for riveting.

[0015] To facilitate effective riveting of both ends and the middle of the riveting plate 103 using a uniformly stressed riveting assembly, in this embodiment, preferably, the uniformly stressed riveting assembly includes a fixing ring 1031 fitted onto the outer surface of the cylinder 105. Reinforcing plates 1032 are integrally provided on both sides of the fixing ring 1031, and the ends of the reinforcing plates 1032 are fixed to the upper surface end of the riveting plate 103 by fixing bolts. Two mounting bolts 1033 are threaded onto both sides of the fixing ring 1031. The cylinder 105... The bottom of cylinder 105 has internal threaded holes 1034 on both sides that match the mounting bolts 1033. The retaining ring 1031 can be closed on the bottom surface of cylinder 105. The mounting bolts 1033 are rotated and inserted into the internal threaded holes 1034 to fix the retaining ring 1031 and the reinforcing plate 1032. The bottom end of the reinforcing plate 1032 is then fixed to the end surface of the riveting plate 103 with the fixing bolts. When the riveting plate 103 is riveted, the middle position and both ends are evenly supported by force for riveting.

[0016] To facilitate the reinforcement and installation of the fixing bolts at the connection between the riveting plate 103 and the cylinder 105 using an auxiliary reinforcement component, in this embodiment, preferably, the auxiliary reinforcement component includes an extension plate 1036 integrally disposed on the lower surface of the fixing ring 1031. An adjusting bolt 1035 is threadedly connected to the inside of the extension plate 1036. A fastening plate 1037 is welded and fixed to the end of the adjusting bolt 1035 on the inner surface of the extension plate 1036. The extension plate 1036 can be closed on the surface of the riveting plate 103 corresponding to the fixing bolt. Rotating the adjusting bolt 1035 will cause the fastening plate 1037 to press tightly against the surface of the fixing bolt, thereby strengthening the installation and enhancing the stability of the installation.

[0017] The ejection mechanism includes ejection components located at both ends inside the riveting base plate 102. A toggle adjustment component is provided on one side of the ejection component. When it is difficult to remove some of the riveted copper tubes, the ejection mechanism can eject the copper tubes for easy removal. If the copper tubes can be easily removed, the ejection mechanism can be ignored.

[0018] To facilitate the removal of the riveted copper tube using the ejection assembly, in this embodiment, preferably, the ejection assembly includes limiting grooves 1024 formed at both ends inside the riveting base plate 102. A release plate 1021 is internally positioned within the limiting grooves 1024, and the surface of the release plate 1021 matches the internal surface structure of the riveting base plate 102. A return spring 1025 is welded to the connection between the bottom end of the release plate 1021 and the bottom end of the limiting groove 1024. After riveting, the return spring 1025 deforms, causing the release plate 1021 to elastically press against the inside of the limiting groove 1024. The inner surface of the release plate 1021 matches the inner surface of the riveting base plate 102, facilitating riveting. After riveting, the release plate 1021 is ejected for easy removal. For removable tubes, the release plate 1021 can be disregarded.

[0019] In order to facilitate the removal of the copper tube by adjusting the release plate 1021, the preferred embodiment of this embodiment includes a sliding groove 1022 located on one side of the limiting slide groove 1024 at the end of the riveting base plate 102. The sliding groove 1022 is provided with a lever 1023. The end of the lever 1023 is threadedly connected to the side of the release plate 1021 by a threaded post. When the copper tube is difficult to remove after riveting, the lever 1023 is adjusted to push the release plate 1021 out, thereby pushing out the copper tube for easy removal.

[0020] The working principle and usage process of this utility model are as follows: When using this pneumatic riveting device, the lower surface of the fixed base 101 contacts the tabletop where the operation is performed and is fixedly installed by fixing bolts. The cylinder 105 is connected to an external air source. After the main body 100 of the riveting device is fixedly installed, when riveting the copper tube, the copper tube is placed on the surface of the riveting base plate 102. Pressing the pneumatic switch 107 opens the solenoid valve through the controller. After the solenoid valve is opened, it provides an external air source to the cylinder 105 to move. The cylinder 105 drives the riveting plate 103 to move down and rivet on the upper surface of the riveting base plate 102 for pneumatic riveting operation. Before the riveting device body 100 is used, the release plate 1021 is elastically reset inside the limiting slide groove 1024 by the return spring 1025, and the surface of the release plate 1021 matches the inner surface of the riveting base plate 102. At this time, when the copper tube is placed inside the riveting base plate 102 for riveting, the release plate 1021 is not affected. After the riveting process, when the copper tube enters the inside of the riveting base plate 102 and is difficult to remove, the sliding lever 1023 inside the sliding groove 1022 drives the release plate 1021 to come out. When the release plate 1021 comes out, it drives the copper tube inside to push out to the outside. When some copper tubes are difficult to remove after riveting, it is convenient to remove them, thus improving the convenience of removing the riveting device body 100 during the riveting process. Finally, before using the riveting device body 100, the retaining ring 1031 is fitted onto the bottom surface of the cylinder 105. After the riveting plate 103 is fixed to the bottom of the cylinder 105 with the fixing bolts, the mounting bolt 1033 is rotated again to embed into the internal threaded hole 1034 to fix the retaining ring 1031. After fixing, the bottom end of the reinforcing plate 1032 is fixed to the surface of the riveting plate 103 by the fixing bolts. At the same time, the extension plate 1036 on the lower surface of the retaining ring 1031 is rotated to align with the surface of the fixing bolts used for installing the riveting plate 103. Adjusting bolt 1035 drives fastening plate 1037 to press against the surface of fixing bolt, which facilitates the installation of cylinder 105 and riveting plate 103 and strengthens the fixed installation. Therefore, when cylinder 105 drives riveting plate 103 to move down for riveting, the reinforcing plate 1032 applies force to both ends of riveting plate 103, so that riveting plate 103 is evenly stressed and riveted. Under frequent riveting stress, riveting plate 103 is less likely to loosen. The fixed riveting treatment is strengthened, and the uniformity and reinforcement of the force on riveting plate 103 by the main body 100 of riveting device during riveting treatment are improved.
