[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] A helmet strap riveting machine, such as Figure 1 As shown, the riveting machine assembles the helmet strap onto the helmet using rivets. Helmets include cycling helmets, safety helmets, etc.

[0027] The riveting machine includes a machine base 1, a top plate 2 fixedly mounted on the machine base 1, and a cylinder 4 fixedly mounted below the top plate 2. The cylinder 4 outputs downwards, and a pressure rod is fixedly connected to the output end of the cylinder 4. An installation cavity is provided inside the pressure rod, and an electromagnet is fixedly mounted inside the installation cavity. This is existing technology. When energized, the electromagnet attracts the rivet located at the lower end of the pressure rod, so that the end of the rivet is tightly fitted with the pressure rod.

[0028] An arc-shaped component 3 is fixedly provided on one side of the top plate 2. A material storage groove is provided inside the arc-shaped component 3, and rivets are stored in the material storage groove.

[0029] like Figures 2-3 As shown, the lower end of the arc-shaped part 3 faces the positioning sleeve 7. The positioning sleeve 7 is fixedly installed below the top plate 2. The side of the positioning sleeve 7 facing the arc-shaped part 3 is provided with a feeding groove. The positioning sleeve 7 guides the rivet. When the rivet enters the positioning sleeve 7 from the arc-shaped part 3, it is attracted to the lower end of the pressure rod by the electromagnet.

[0030] In this embodiment, a material blocking structure is provided on one side of the arc-shaped part 3 to restrict the rivet at the lower end of the arc-shaped part 3. During the riveting process, the material blocking structure is provided to prevent the subsequent rivet from falling. The material blocking structure includes an electric cylinder or a hydraulic cylinder. After the output end of the electric cylinder or hydraulic cylinder contacts the rivet located at the bottom of the arc-shaped part 3, it limits the rivet and prevents it from falling.

[0031] A column 5 is fixedly installed on the machine base 1 and below the cylinder 4. A support base 6 is fixedly installed on the column 5. An installation rod 61 is fixedly installed on the support base 6. A support plate 64 is fixedly installed on the side of the installation rod 61. A threaded groove 65 is opened on one side of the installation rod 61.

[0032] A positioning rod 62 is fixedly provided on the mounting rod 61, and an arc surface 63 is provided at the connection between the positioning rod 62 and the mounting rod 61.

[0033] A placement plate 8 is fixedly mounted on the support plate 64. A connecting pipe 83 is fixedly mounted below the placement plate 8. The connecting pipe 83 is fitted onto the outside of the mounting rod 61. A screw passes through the side of the connecting pipe 83 and connects to the threaded groove 65. Symmetrically distributed limiting rods 81 are fixedly mounted on the placement plate 8. An arc plate 82 is fixedly mounted on the connecting pipe 83. A circular hole 84 is provided in the middle of the arc plate 82. The circular hole 84 mates with the arc surface 63. The arc plate 82 fits against the arc surface 63 to support the placement plate 8.

[0034] During assembly, the metal parts at both ends of the hood strap are fitted onto the positioning rod 62 and then slide down onto the placement plate 8, positioned between the two limiting rods 81. After fixing the metal parts, the hood strap mounting holes on the helmet are aligned with the positioning rod 62. Then, the hollow rivet rod is moved to the lower end of the pressure rod, and the pressure rod is moved down by the cylinder 4 to press the hollow rivet rod into the positioning rod 62. The lower end of the hollow rivet rod is fitted onto the positioning rod 62 and is located in the helmet hood strap mounting hole until the lower end of the rivet rod is flipped outward under the guidance of the arc surface 63. After passing through the arc plate 82, the flipped fold is placed under the metal parts. The upper end of the hollow rivet rod is riveted into a protrusion and located outside the helmet, thereby fixing the metal parts to the helmet.

[0035] Example 2

[0036] Based on Example 1, an electric slide is fixedly installed on the machine base 1. The electric slide is vertically installed on the machine base 1, and the top plate 2 is fixedly installed on the slider of the electric slide. The slider is controlled to move vertically by the electric slide, and then the top plate 2 is moved to adjust the height of the top plate 2 in order to achieve different processing heights to suit the riveting production of helmets of different sizes.
