[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Refer to Figures 1-4 , a riveting press, including a base 1 and a frame 2 arranged on the top of the base 1. A stamping unit 3 is provided on the top of the frame 2. The stamping unit 3 uses a hydraulic cylinder to cooperate with a stamping head for stamping. A support block 4 is fixed inside the frame 2, and a limit post 5 is provided on the top of the support block 4; a fixed seat 7 is detachably connected to the surface of the support block 4 through a connecting mechanism 6, and a guiding mechanism 8 is provided between the support block 4 and the fixed seat 7. The top of the fixed seat 7 is movably connected to a U-shaped plate 10 through a height adjusting component 9. Anti-slip structures 11 are provided on both sides of the top of the U-shaped plate 10; this riveting press can support larger riveting plate parts through the U-shaped plate 10, improving the stability during processing. The height of the U-shaped plate 10 can be adjusted by the screw 93 to suit different workpieces. The positioning piece can be conveniently disassembled and installed through the stud 61 and the threaded sleeve 64, facilitating replacement. The rubber anti-slip strip 113 on the top can prevent the riveting plate parts from sliding, improving the processing stability during riveting.

[0022] In this embodiment, the connecting mechanism 6 includes a stud 61 fixed to the front of the support block 4. A convex block 62 is fixed to the bottom of the fixed seat 7, and a through hole 63 is opened on the surface of the convex block 62. The stud 61 passes through the through hole 63 and is threadedly connected to a threaded sleeve 64, and the threaded sleeve 64 can fix the fixed seat 7.

[0023] Further, the guiding mechanism 8 includes L-shaped limiting frames 81 fixed to both sides of the support block 4. Positioning holes 82 are formed in the side surfaces of the L-shaped limiting frames 81. At least two positioning blocks 83 are fixed to the outer ends of the fixed seats 7. The positioning blocks 83 are clamped with the positioning holes 82. The positioning blocks 83 and the positioning holes 82 can accurately fix the other end of the fixed seat 7, thereby effectively increasing the stability of the entire structure and effectively preventing the fixed seat 7 from shifting when subjected to external forces.

[0024] Furthermore, the height adjustment assembly 9 includes a first side plate 91 fixed to one side of the U-shaped plate 10 and a second side plate 92 fixed to one side of the fixed seat 7. A screw rod 93 is rotatably connected to the bottom of the first side plate 91. The screw rod 93 is threadedly connected to the second side plate 92.

[0025] In addition, a number of guiding grooves 12 are formed inside the fixed seat 7, and a number of guide posts 13 are fixed to the bottom of the U-shaped plate 10. The guide posts 13 are slidably connected to the guiding grooves 12. The guide posts 13 cooperating with the guiding grooves 12 can guide the lifting of the fixed seat 7.

[0026] It should be noted that the anti-slip structure 11 includes fitting grooves 111 formed on both sides of the top of the U-shaped plate 10 and fixing plates 112 movably connected inside the fitting grooves 111. A number of rubber anti-slip strips 113 are fixed to the tops of the fixing plates 112. Semi-circular grooves 114 are formed on both sides of the fitting grooves 111, and pulling blocks 115 for pulling are fixed to both sides of the fixing plates 112.

[0027] Working method: When performing riveting and pressing processing, the staff pushes the fixed seat 7 inward along the L-shaped limiting frame 81 until the positioning block 83 is clamped with the positioning hole 82. Then, the stud 61 passes through the through hole 63 and is fixed with the threaded sleeve 64. After the fixing is completed, the screw rod 93 can be rotated by hand. The screw rod 93 can drive the U-shaped plate 10 to move up and down for adjustment. When performing riveting and pressing processing, the riveting plate is placed on the U-shaped plate 10. The rubber anti-slip strips 113 can prevent the riveting plate from slipping. To replace the fixing plate 112, the pulling block 115 can be directly toggled to take out the fixing plate 112 for replacement.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
