[0026] Example 1

[0027] like Figures 1-6As shown, this embodiment proposes an automatic punching machine for nut production, including an operating table body 1 and a punching machine body 2. The upper end face of the operating table body 1 is provided with a punching groove directly below the punch of the punching machine body 2. A U-shaped frame 3 is fixedly installed on one side of the upper end face of the operating table body 1. The punching machine body 2 is set on the U-shaped frame 3. Limiting and fixing components 100 are provided on both sides of the bottom of the U-shaped frame 3. Fixed baffles 4 are fixedly installed on both sides of the upper end face of the operating table body 1. Electric push rods 5 are fixedly installed on both sides of the two fixed baffles 4. The input end of the electric push rods 5 is connected to the power supply through an external cable. Limiting baffles 6 are fixedly installed on the output ends of every two electric push rods 5. A conveying component 200 is provided inside the operating table body 1.

[0028] The limiting and fixing assembly 100 includes a support vertical plate 101 fixedly installed on one side of the bottom of the U-shaped frame 3. A connecting seat 102 is fixedly installed on one side of the top of the support vertical plate 101. An electric push rod 103 is rotatably connected to the connecting seat 102. The input end of the electric push rod 103 is connected to a power source via an external cable. An L-shaped support rod 104 is rotatably connected to the output end of the electric push rod 103. A connecting column 105 is fixedly installed at one corner of the L-shaped support rod 104. One end of the connecting column 105 is rotatably connected to one side of the support vertical plate 101. An electric push rod 106 is fixedly installed on one side of the support vertical plate 101. The input end of the electric push rod 106 is connected to a power source via an external cable. A movable plate 107 is fixedly installed at the output end of the electric push rod 106. T-shaped sliders 8 are symmetrically fixedly installed on one side of the movable plate 107. T-shaped grooves 9 matching the T-shaped sliders 8 are symmetrically opened on one side of the support vertical plate 101. The T-shaped sliders 8 are located within the T-shaped grooves 9. The sliding connection has guide rods 108 symmetrically fixedly installed on one side of the movable plate 107, and a fixed plate 109 fixedly installed on one side of the supporting vertical plate 101. One end of each guide rod 108 extends movably through to one side of the fixed plate 109 and is fixedly installed with a connecting block 110. One side of the connecting block 110 is in contact with one side of the supporting vertical plate 101. Guide rods 111 symmetrically slide through the connecting block 110. One end of each guide rod 111 is fixedly installed with the same slide rail 112. One end of the L-shaped support rod 104 is rotatably connected to a rotating column 7. One end of the rotating column 7 extends into the slide rail 112 and matches the side wall of the slide rail 112. The other end of each guide rod 111 is fixedly installed with the same clamping plate 113. The two clamping plates 113 are symmetrically arranged on both sides of the punching slot. The shape of the clamping plate 113 matches the shape of the nut. An extension edge is provided on the top of the clamping plate 113, and the outer side of the extension edge is far away from the outer side of the punching hole.

[0029] The nut can be effectively clamped and fixed by the set limit fixing component 100. When the nut needs to be clamped and fixed, firstly, when the nut is conveyed to the bottom of the punching machine body 2, then the electric push rods 103 on both sides of the U-shaped frame 3 are activated to push the corresponding L-shaped support rods 104 to rotate. When the L-shaped support rods 104 rotate, through the cooperation between the rotating column 7 and the slide rail 112, the clamping plate 113 on one side of the guide rod 111 moves closer to the side of the nut. Then, the electric push rod 106 is activated to drive the guide rod 108 on one side of the moving plate 107 to move. The guide rod 108 drives the clamping plate 113 on one side of the connecting block 110 to move downward, thereby squeezing the top of the nut and clamping and fixing the nut.

[0030] Example 2

[0031] like Figures 1-6 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a conveyor assembly 200 including symmetrically arranged conveyor belts 201. The upper end face of the operating platform body 1 has symmetrically arranged slots 202 on both sides, the distance between the two slots 202 being greater than the diameter of the nut punch hole. The operating platform body 1 has symmetrically arranged movable slots 203 on both sides, each movable slot 203 containing a U-shaped support rod 204. One U-shaped support rod 204 is rotatably connected to a rotating roller 205, and the other U-shaped support rod 204 has a dual-axis motor 206 fixedly installed in the middle of its upper end face. The input end of the dual-axis motor 206 is connected to a power source via an external cable, and two rotating rollers 207 are fixedly installed at both output ends of the dual-axis motor 206. The two rotating rollers 207 and the rotating roller 205 are connected by the conveyor belt 201. The conveyor belt 201 matches the slots 202. One end of the rotating roller 207 is rotatably connected to one side of the U-shaped support rod 204. Hydraulic cylinders 208 are fixedly installed on both sides of the bottom wall of the two movable grooves 203 symmetrically between the U-shaped support rod 204 and the bottom wall of the two movable grooves 203. The input end of the hydraulic cylinder 208 is connected to the power supply through an external cable. The set transmission component 200 can automatically transmit the nut to the bottom of the punching machine body 2. When it is necessary to automatically transmit the nut to the bottom of the punching machine body 2, firstly, the hydraulic cylinder 208 is started to drive the conveyor belt 201 on the U-shaped support rod 204 to rise above the through groove 202. Then, the dual-axis motor 206 is started to drive the nuts on the two conveyor belts 201 to be transmitted. When the nut is transmitted to the bottom of the punching machine body 2, the hydraulic cylinder 208 drives the U-shaped support rod 204 to descend into the through groove 202. The nut falls on the upper end face of the operating table body 1, thereby automatically transmitting the nut to the bottom of the punching machine body 2.

[0032] During operation, firstly, the electric push rod 5 is activated according to the diameter of the nut, driving the two limit baffles 6 to move relative to each other and clamp the nut. Then, the nut to be punched is placed between the two limit baffles 6. Next, the hydraulic cylinder 208 is activated to drive the conveyor belt 201 on the U-shaped support rod 204 to rise above the slot 202, with the nut positioned on the conveyor belt 201. Then, the dual-axis motor 206 is activated to drive the nuts on the two conveyor belts 201 to be conveyed. When the nut is conveyed to directly below the punching machine body 2, the hydraulic cylinder 208 drives the U-shaped support rod 204 to descend into the slot 202, and the nut falls into the operating position. The upper surface of the worktable body 1 is then activated. The electric push rods 103 on both sides of the U-shaped frame 3 are simultaneously driven to rotate the corresponding L-shaped support rods 104. As the L-shaped support rods 104 rotate, they are pushed by the cooperation between the rotating column 7 and the slide rail 112 to move the clamping plate 113 on one side of the guide rod 111 closer to the nut side. Then, the electric push rod 106 is activated to drive the guide rod 108 on one side of the moving plate 107 to move. The guide rod 108 drives the clamping plate 113 on one side of the connecting block 110 to move downward, thereby pressing and fixing the top of the nut. Then, the punching machine body 2 is activated to perform a punching operation on it.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
