[0026] Please see Figures 1-5 The present invention provides a quick-change mold device for an automatic riveting machine with error prevention, comprising a housing 1.

[0027] Reference Figure 1 and Figure 3As shown, the housing 1 has a disassembly and assembly structure 2 inside. The disassembly and assembly structure 2 includes a first connecting rod 201, a rack 202, a first gear 203, a first limiting rod 204, a first limiting block 205, a second limiting rod 206, a second gear 207, a first synchronous pulley 208, a second synchronous pulley 209, a second connecting rod 210, a third connecting rod 211, a slider 212, a slide rail 213, and a handle 214. The first connecting rod 201 passes through the interior of the housing 1. A rack 202 is installed at both ends of the first connecting rod 201. A first gear 203 is provided on the side of the rack 202 away from the first connecting rod 201. A first limiting rod 204 is fixed on both sides of the first gear 203. Four sets of positioning rods 204 are provided. Two sets of first positioning rods 204 have first positioning blocks 205 on their exterior. A second positioning rod 206 passes through the exterior of the first positioning rod 204 inside the first positioning block 205. A second gear 207 is fixed to one side of the second positioning rod 206. A first synchronous pulley 208 is fixed to the side of the second positioning rod 206 away from the second gear 207. A second synchronous pulley 209 is provided on the top of each first synchronous pulley 208. A second connecting rod 210 is installed on one side of the second synchronous pulley 209. A third connecting rod 211 is installed on the side of the second connecting rod 210 away from the second synchronous pulley 209. A slider 212 is provided on the exterior of the third connecting rod 211. The bottom of the slider 212 is... The housing 1 is equipped with a slide rail 213, a first connecting rod 201 extending to the outside of the housing 1 and fitted with a handle 214, the housing 1 being slidably connected to the first connecting rod 201, the housing 1 being slidably connected to the rack 202, the housing 1 being rotatably connected to the first limiting rod 204, the housing 1 being fixedly connected to the first limiting block 205, the housing 1 being connected to the second synchronous wheel 209 via a shaft, the housing 1 being slidably connected to the third connecting rod 211, the housing 1 not being connected to the slider 212, and the housing 1 not being connected to the slide rail 213. The first connecting rod 201 is T-shaped, the rack 202 is meshed with the first gear 203, the first gear 203 is meshed with the second gear 207, and the first limiting rod 204 is connected to the first limiting block 205. 5. Rotary connection: The second limiting rod 206 is rotatably connected to the first limiting block 205. Four sets of second synchronous wheels 209 are provided. Two sets of second synchronous wheels 209 are connected to the first synchronous wheel 208 by belt. Every two sets of second synchronous wheels 209 are integrated. The second synchronous wheel 209 is connected to the second connecting rod 210 by shaft. The second connecting rod 210 is connected to the third connecting rod 211 by shaft. The third connecting rod 211 is not connected to the slider 212. The slider 212 is slidably connected to the slide rail 213. The top surface of the housing 1 is welded with a clamping structure 3. A mold base 4 is installed on the opposite side of the clamping structure 3. The main body 5 is installed inside the housing 1. The sliders 212 are all fixedly connected to the mold base 4.

[0028] The sliding handle 214 drives the slide rail 213 to rise and fall, and at the same time drives the third connecting rod 211 to slide inside the housing 1, so that it moves closer to or away from the slider 212, thereby improving stability. When the slide rail 213 rises to the top of the housing 1, the sliding mold base 4 drives the slider 212 away from the slide rail 213, thus enabling the device to be easily disassembled and replaced with the mold base 4.

[0029] Reference Figure 2 and Figure 4 As shown, the clamping structure 3 includes a second limiting block 301, a sliding rod 302, a spring 303, a clamping block 304, a roller 305, and a rubber layer 306. The bottom end of the second limiting block 301 is welded to the top surface of the housing 1. The sliding rod 302 passes through the interior of the second limiting block 301. The spring 303 is provided on the outside of the sliding rod 302 extending to the outside of the second limiting block 301. The clamping block 304 is fixed to one side of the spring 303. Rollers 305 are installed on both sides of the bottom of the clamping block 304. The rubber layer 306 is pasted on the side of the clamping block 304 away from the spring 303. The second limiting block 301 is slidably connected to the sliding rod 302. The second limiting block 301 is fixedly connected to the spring 303. The sliding rod 302 is fixedly connected to the clamping block 304. The clamping block 304 is connected to the roller 305 through a shaft. The roller 305 is in contact with the housing 1 but not connected. The rubber layer 306 is in contact with the mold base 4 but not connected.

[0030] The pusher 304 drives the roller 305 to rotate on the top surface of the housing 1, and at the same time drives the slide bar 302 to slide inside the second limit block 301, so that the rubber layer 306 moves away from the mold base 4. When the pressure of the spring 303 is released, the roller 305 can clamp the mold base 4, improving its stability. The rubber layer 306 has good anti-slip properties, realizing the function of improving the stability and friction of the mold base 4.

[0031] In summary, as Figures 1-5As shown, in use, the riveting machine device pushes the clamping block 304, which drives the roller 305 to roll on the top surface of the housing 1. The clamping block 304 drives the slide bar 302 to slide inside the second limiting block 301. The spring 303 is retracted under pressure, simultaneously moving the rubber layer 306 away from the mold base 4. The handle 214 slides upward, and the handle 214 drives the rack 202 to move upward through the first connecting rod 201. The rack 202 drives the slide rail 213 to move to the top of the housing 1. The rack 202 drives the first connecting rod 201 to move the second limiting block 301. When gear 203 rotates, it drives the first limiting rod 204 to rotate inside the first limiting block 205. Simultaneously, gear 203 drives the second gear 207 to rotate, which in turn drives the second limiting rod 206 to rotate inside the first limiting rod 204. The second limiting rod 206 then drives the first synchronous pulley 208 to rotate. The first synchronous pulley 208, via a belt, drives two sets of second synchronous pulleys 209 to rotate, which in turn drive two other sets of second synchronous pulleys 209 to rotate. The second synchronous wheel 209 drives the third connecting rod 211 to slide inside the housing 1 via the second connecting rod 210, thereby placing the third connecting rod 211 outside the slider 212. The sliding mold base 4 drives the slider 212 to slide on the top of the slide rail 213 until the slider 212 moves away from the slide rail 213, thereby removing the mold base 4. During installation, slide the slider 212 to the top of the slide rail 213 and slide the handle 214 down. When the mold base 4 contacts the housing 1, the clamping block 304 is released, and the pressure received by the spring 303 is released, which drives the rubber layer 306 to clamp the mold base 4 through the clamping block 304, thereby stabilizing the position of the mold base 4 and preventing the mold base 4 and the main body 5 from misaligning during operation. The top of the mold base 4 is provided with a rotary drive mechanism to drive the rivet to rotate. The main body 5 is provided with a stamping machine, which applies pressure to the rivet through a pressure mechanism, causing the tail of the rivet to undergo plastic deformation, forming an expansion, and tightly filling the pre-made hole in the workpiece, thereby achieving a firm connection.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
