Detailed Implementation
[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] See Figures 1 to 5 This embodiment discloses a riveting fixture, including a bracket 100. The bracket 100 is connected to a first support plate 110 located above and a second support plate 120 located below the first support plate 110. A power source 200, which is a cylinder, is mounted on the first support plate 110. The output shaft 201 of the power source 200 extends vertically toward the second support plate 120. A first connector 210 is threaded to the end of the output shaft 201, and a second connector 220 is threaded to the first connector 210. A riveting head 230 is threaded to the second connector 220. The second support plate 120 has an installation opening 600, into which a support seat 300 is embedded. The workpiece 500 to be processed and the rivet are placed between the riveting head 230 and the support seat 300, thereby performing a riveting operation on the workpiece 500.
[0023] The support base 300 includes a riveting part 310, a support part 320, and a limiting part 330. The riveting part 310 faces the riveting head 230. The diameter of the support part 320 is larger than the diameter of the mounting opening 600, so that the support part 320 abuts against the mounting opening 600. The limiting part 330 is adapted to the shape of the mounting opening 600, so that it can be embedded in the mounting opening 600.
[0024] The second support plate 120 is fitted with a limiting sleeve 400, which abuts against the upper end face and side face of the support portion 320, thereby preventing the support base 300 from disengaging from the limiting sleeve 400 of the mounting opening 600 and ensuring the stability of the support portion 320 during installation. The limiting sleeve 400 includes a first limiting plate 410 and a second limiting plate 420, both of which surround the support portion 320. The first limiting plate 410 is located above and in contact with the upper end face of the support portion 320, while the second limiting plate 420 is located on the side of the support portion 320. The side of the second limiting plate 420 facing the support portion 320 has a first abutting portion 421, which abuts against the side face of the support portion 320, thereby allowing the limiting sleeve 400 to cover the support portion 320 to restrict the movement of the support base 300 and ensure the stability of the fixed support base 300.
[0025] A first inclined surface 321 is provided at the connection between the upper end face and the side face of the support portion 320. The support base 300 also includes a second abutment portion 430 perpendicular to the first inclined surface 321. The second abutment portion 430 extends from the connection between the first limiting plate 410 and the second limiting plate 420 toward the first inclined surface 321. The second abutment portion 430 can apply a downward inclined pressure to the support base 300, thereby restricting the horizontal movement of the support base 300. This prevents displacement of the support base 300 when the riveting head 230 presses down, which could cause misalignment between the workpiece 500 and the riveting portion 310 and affect accuracy.
[0026] The mounting opening 600 is provided with a third inclined surface 610 that slopes towards the center of the mounting opening 600. The limiting part 330 includes a second inclined surface 331 that mates with the third inclined surface 610. When the limiting part 330 is inserted into the mounting opening 600, the second inclined surface 331 and the third inclined surface 610 are in contact. The second inclined surface 331 and the third inclined surface 610 serve as guides, ensuring that the support 300 is centered when placed into the mounting opening 600. They also further limit the horizontal movement of the support 300, thereby preventing misalignment between the workpiece 500 and the riveting part 310.
[0027] The third inclined surface 610 is provided with a first protruding ring 611 near the upper end face of the second support plate 120, and the second inclined surface 331 is provided with a first groove 332, in which the first protruding ring 611 is embedded. The third inclined surface 610 is provided with a second protruding ring 612 near the lower end face of the second support plate 120, and the second inclined surface 331 is provided with a second groove 333, in which the second protruding ring 612 is embedded. The engagement of the first protruding ring 611 with the first groove 332 and the engagement of the second protruding ring 612 with the second groove 333 serves a positioning function, thereby preventing slippage between the third inclined surface 610 and the second inclined surface 331 and ensuring the stability of the support base 300 installation.
[0028] The second support plate 120 has a fixing groove 122 surrounding the mounting opening 600. A first locking block 121 is provided in the fixing groove 122, and a limiting sleeve 400 is provided with a second locking block 422 embedded in the fixing groove 122. The lower end face of the limiting sleeve 400 is inserted into the groove of the fixing groove 122, thereby placing the second locking block 422 below the first locking block 121. Rotating the limiting sleeve 400 can cause the first locking block 121 to abut against the second locking block 422, thereby preventing the limiting sleeve 400 from disengaging from the fixing groove 122, ensuring the stability of the fixing between the fixing groove 122 and the second support plate 120, and thus ensuring the stability of the fixing of the support base 300.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
