Description

TECHNICAL FIELD

[0001] The utility model relates to a nut production equipment technical field especially, it relates to a kind of lock piece blow feeding mechanism for the pressure riveter used in full-automatic riveting between sheet metal lock nut. BACKGROUND

[0002] In the nut production field, pressure riveter generally refers to the production equipment for lock nut, and its working principle is to connect the lock piece by pressure riveting.

[0003] At present, the production of nylon lock piece on lock nut (i.e. the pressure riveting process of nylon lock piece on lock nut) is basically automated, but the metal lock piece on the market has problems such as small thickness and easy bending deformation, so if it is directly cut in the same way as the nylon lock piece, it is easy to produce problems such as jumping, stacking and jamming; Therefore, only a small part of factories can realize full-automatic production through automatic equipment, and most factories still use manual lock piece feeding and automatic pressure riveting to realize semi-automatic production mode; In the existing equipment that can realize automatic production, in addition to the mechanical arm mode of crank rocker suction cup or the mode of vertical cutting with push rod (when the two modes of mechanical arm or vertical cutting with push rod are found, the structure of the automatic equipment realized usually has relatively complex structure, which causes relatively high cost in production, and the assembly process is also relatively complex and not easy to maintain);

[0004] It also relates to a full-automatic pressure riveter for metal lock nut with relatively simplified structure, which can realize efficient assembly between metal sheet and lock nut, but in the process of feeding lock piece, the feeding part of lock piece can be vibrated by vibrator to prevent stacking, jamming and other problems during feeding, but in actual use, the full-automatic pressure riveter may not cause stacking, jamming and other problems during use, but the vibrator will not vibrate indefinitely, and the lock piece in the feeding part may be stuck due to shutdown, which may cause failure during use of the full-automatic pressure riveter. SUMMARY

[0005] In view of the above problems, the utility model provides a full-automatic pressure riveter for metal lock nut with lock piece blow feeding mechanism, which can ensure reliable feeding of lock piece even if the equipment is accidentally stopped and restarted.

[0006] To achieve the above objectives, this utility model employs a locking plate air-blowing feeding mechanism for a fully automatic metal sheet anti-loosening nut riveting machine, including a locking plate feeding mechanism, a locking plate feeding channel, and a locking plate air-blowing mechanism. The locking plate feeding channel includes a channel body and a locking plate inlet and a locking plate outlet distributed on the channel body. The locking plate inlet is located on one side of the locking plate feeding mechanism, and the locking plate outlet is located on one side of the locking plate pushing mechanism on the external riveting machine. The locking plate air-blowing mechanism includes an air-blowing part facing the locking plate inlet and an air inlet part for introducing air into the air-blowing part.

[0007] The air inlet is connected to the air blowing section, and the air blowing section is connected to the locking plate feed port. The air entering the locking plate feed port is simultaneously blown into the channel body, and the locking plate in the channel body is blocked or stuck to the channel wall in the channel body and blown away.

[0008] The present invention is further configured such that the locking plate blowing mechanism also includes an air inlet pipe, one end of which is connected to the air inlet section, and the other end is connected to the exhaust gas discharge end of the locking plate push cylinder of the external locking plate pushing mechanism. The exhaust gas discharged from the exhaust gas discharge end of the external locking plate push cylinder is directly used to drive the locking plate in the channel body to be blown away from the jamming or adhesion between it and the channel wall in the channel body. This forms the driving stage of the external locking plate push cylinder pushing the locking plate. The discharged exhaust gas directly acts on the channel body, causing the locking plate in the channel body to make a feeding action towards the locking plate pushing mechanism through the locking plate discharge port.

[0009] The present invention is further configured such that the locking plate blowing mechanism is located between the feeding area of ​​the locking plate feeding mechanism and the locking plate feeding channel, and the locking plate blowing mechanism further includes an air inlet block and an air blowing block connected in sequence. The air inlet block has an air inlet channel, and the air blowing block has an air blowing channel connected to the air inlet channel. The air inlet part is distributed on the air inlet channel and located at the other end connected to the air blowing channel, and the air blowing part is distributed on the air blowing channel and located at the other end connected to the air inlet channel.

[0010] The present invention is further configured such that the locking plate blowing mechanism also includes a blowing mechanism auxiliary limiting block, the blowing mechanism auxiliary limiting block is connected to the blowing block and is distributed in a frame-like manner on the side facing the locking plate feeding mechanism, and the locking plate feeding port is a locking plate insertion hole opened on the side facing the locking plate feeding mechanism.

[0011] The beneficial effects of this utility model are as follows: By incorporating a locking plate air blowing mechanism into one side of the locking plate feeding channel of the fully automatic metal sheet anti-loosening nut riveting machine, and simultaneously incorporating an air blowing section facing the locking plate feeding port and an air intake section for introducing air into the air blowing section, the air intake section and the air blowing section are connected, and the air blowing section and the locking plate feeding port are connected. Therefore, during the feeding process, the locking plate part of the riveting machine can be blown into the locking plate feeding channel by the air intake section of the locking plate air blowing mechanism. This improves the problem of adhesion between the locking plate and the inner wall of the locking plate feeding channel when the riveting machine is stopped and restarted. This significantly reduces the problem of locking plate feeding failure caused by the locking plate sticking to the inner wall of the locking plate feeding channel after the machine stops, which is a common issue with the riveting machine. Furthermore, with the locking plate blowing mechanism, if the locking plate gets blocked in the locking plate feeding channel, it will vibrate in place. While manually pushing the locking plate can usually resolve this blockage, it's impossible to monitor the riveting machine constantly. The locking plate blowing mechanism allows for a simpler method, replacing manual pushing. Attached Figure Description

[0022] like Figures 1-10 As shown, a specific embodiment of this utility model is a locking plate air-blowing feeding mechanism for a fully automatic metal sheet anti-loosening nut riveting machine, including a locking plate feeding mechanism 2, a locking plate feeding channel 3, and a locking plate air-blowing mechanism 4. The locking plate feeding channel 3 includes a channel body 31, and a locking plate feeding port 32 and a locking plate discharging port 33 distributed on the channel body 31. The locking plate feeding port 32 is distributed on one side of the locking plate feeding mechanism 2, and the locking plate discharging port 33 is distributed on one side of the locking plate pushing mechanism on the external riveting machine. The locking plate air-blowing mechanism 4 includes an air-blowing part 45 facing the locking plate feeding port 32, and an air intake part 44 for introducing air into the air-blowing part 45.

[0023] The air inlet 44 is connected to the air blowing section 45, and the air blowing section 45 is connected to the locking plate feed port 32. The air entering the locking plate feed port 32 is simultaneously blown into the channel body 31, and the locking plate c in the channel body 31 is blown away from the channel wall inside the channel body 31, which is stuck or stuck.

[0024] By incorporating a locking plate air blowing mechanism 4 into one side of the locking plate feeding channel 3 of the fully automatic metal sheet anti-loosening nut riveting machine, and simultaneously incorporating an air blowing section 45 facing the locking plate feeding port 32, and an air inlet 44 for introducing air into the air blowing section 45, with the air inlet 44 communicating with the air blowing section 45 and the air blowing section 45 communicating with the locking plate feeding port 32, the locking plate c part of the riveting machine can be blown into the locking plate feeding channel 3 during the feeding process through the air inlet 44 of the locking plate air blowing mechanism 4. This improves the adhesion between the locking plate c and the inner wall of the locking plate feeding channel 3 when the riveting machine is stopped and restarted. This significantly reduces the problem of locking plate c sticking to the inner wall of the locking plate feeding channel 3 after the machine stops, causing feeding failure. In addition, with the locking plate blowing mechanism 4, if the locking plate c is blocked in the locking plate feeding channel 3, it will vibrate in place. In this case, the blockage can usually be solved by pushing it manually. However, during the use of the riveting machine, it is not possible to supervise it all the time. With the locking plate blowing mechanism 4, the locking plate can be blown by the locking plate blowing mechanism 4, which replaces the force of manual pushing.

[0025] like Figures 1-9As shown, the locking plate blowing mechanism 4 also includes an air inlet pipe 1. One end of the air inlet pipe 1 is connected to the air inlet 44, and the other end is connected to the exhaust gas discharge end of the locking plate push cylinder of the external locking plate pushing mechanism. The exhaust gas discharged from the exhaust gas discharge end of the external locking plate push cylinder is directly used to drive the locking plate c in the channel body 31 to break the jamming or adhesion between the locking plate c and the channel wall in the channel body 31. This forms the driving stage for the external locking plate push cylinder to push the locking plate c. The discharged exhaust gas directly acts on the channel body 31, forming a design where the locking plate c in the channel body 31 moves towards the locking plate pushing mechanism through the locking plate outlet 33. The locking plate push cylinder used for pushing the locking plate c recovers the exhaust gas generated during the pushing process and introduces it into the channel body 31. After the corresponding locking piece c is pushed once in the locking piece feeding channel 3, the generated exhaust gas can also be used to blow air into the locking piece feeding channel 3 once. Therefore, the locking piece blowing mechanism 4 does not need to add an air source during the blowing process, which is green and environmentally friendly. Since the blowing rhythm is the same as the riveting rhythm, it can be used directly without adding other accessories or adjusting the timing. This also makes the locking piece blowing mechanism 4 of this utility model low cost and simple design. Since this locking piece blowing mechanism 4 is not subjected to extreme force during use, it can be manufactured by 3D printing, which can further reduce the cost of the locking piece blowing mechanism 4.

[0026] like Figures 1-9 As shown, the locking plate blowing mechanism 4 is located between the feeding area 21 of the locking plate feeding mechanism 2 and the locking plate feeding channel 3. The locking plate blowing mechanism 4 also includes an air inlet block 43 and an air blowing block 42 connected in sequence. The air inlet block 43 has an air inlet channel a, and the air blowing block 42 has an air blowing channel b connected to the air inlet channel a. The air inlet part 44 is distributed on the air inlet channel a and located at the other end connected to the air blowing channel b. The air blowing part 45 is distributed on the air blowing channel b and located at the other end connected to the air inlet channel a. This design allows the locking plate blowing mechanism 4 to be reliably distributed and limited between the locking plate feeding mechanism 2 and the locking plate feeding channel 3. Furthermore, the design of the air inlet channel a and the air blowing channel b further ensures that the air involved in this invention can smoothly enter the locking plate feeding channel 3 for reliable blowing operations.

[0027] like Figure 2 , 4As shown in Figure 5, the locking plate blowing mechanism 4 also includes a blowing mechanism auxiliary limiting block 41. The blowing mechanism auxiliary limiting block 41 is connected to the blowing block 42 and is mounted on the side facing the locking plate feeding mechanism 2. The locking plate feeding port 32 is designed with a locking plate insertion hole on the side facing the locking plate feeding mechanism 2, which allows the locking plate blowing mechanism 4 to be further lifted. After the design, the locking plate blowing mechanism 4 strengthens the connection between the locking plate feeding mechanism 2 and the locking plate feeding channel 3.
