Description

Technical Field

[0001] This utility model relates to the technical field of nut production equipment, and more particularly to a locking plate air-blowing feeding mechanism used in a riveting machine for fully automatic riveting between metal sheet anti-loosening nuts. Background Technology

[0002] In the field of nut manufacturing, a press riveting machine usually refers to the production equipment for anti-loosening nuts. Its working principle is to press rivet the locking plates that are inserted into nylon or metal locking plates.

[0003] Currently, the production of nylon locking plates on anti-loosening nuts (i.e., the crimping connection process between nylon locking plates and anti-loosening nuts) has been largely automated. However, the metal locking plates on the market have problems such as small thickness and easy bending and deformation. If the same material cutting method is used as for nylon locking plates, problems such as plate skipping, stacking, and blockage are likely to occur. Therefore, only a small number of factories can achieve fully automated production through automated equipment. The vast majority of factories still use a semi-automatic production mode for the production of metal locking plate anti-loosening nuts, which involves manually placing the locking plates and using automatic crimping. Among the existing equipment that can achieve automated production, the general methods are either a robotic arm with a crank, rocker arm, and suction cup, or a method with vertical material feeding and push rods. (It has been found that the structure of the automated equipment achieved by the robotic arm method or the method with vertical material feeding and push rods is usually relatively complex. This results in relatively high production costs, as well as relatively complex assembly processes and difficulties in maintenance.)

[0004] It also involves a relatively simplified fully automatic riveting machine for metal sheet anti-loosening nuts. Although it can achieve efficient assembly between metal sheets and anti-loosening nuts, in the process of feeding the locking sheet, the feeding part of the locking sheet is vibrated by a separate vibrator to prevent stacking, blockage and other issues during the feeding process. However, in actual use, it has been found that setting up a separate vibrator will increase the design cost of the fully automatic riveting machine. Summary of the Invention

[0005] In view of the above shortcomings, this utility model provides a locking plate tilting feeding mechanism for a fully automatic metal sheet anti-loosening nut riveting machine that can achieve reliable feeding process while reducing the production and manufacturing cost of the riveting machine.

[0006] To achieve the above objectives, this utility model employs a locking plate tilting feeding mechanism for a fully automatic metal sheet anti-loosening nut riveting machine. It includes a locking plate feeding channel, a locking plate feeding mechanism for vibratory feeding of the locking plates, and a tilting mechanism. The locking plate feeding channel includes a channel body and locking plate inlets and outlets distributed on the channel body. The locking plate inlets are located on one side of the locking plate feeding mechanism, and the locking plate outlets are located on one side of the locking plate pushing mechanism on an external riveting machine. The tilting mechanism is connected to both the channel body and the locking plate feeding mechanism. Through the tilting mechanism, the vibration force of the locking plate feeding mechanism is transmitted to the locking plate feeding channel, accelerating the feeding of the locking plates through vibration. The locking plate inlet is a locking plate insertion hole opened on the side facing the locking plate feeding mechanism.

[0007] The present invention is further configured such that the tilting mechanism includes a tilting plate and a vibration force transmission plate, the vibration force transmission plate being confined on the tilting plate, the tilting plate being connected to the locking plate feeding mechanism and extending to one side of the channel body, and the vibration force transmission plate confined on the tilting plate extending to one side of the channel body along with the tilting plate and connecting to the channel body.

[0008] The present invention is further configured such that the vibration force transmission plate includes a force transmission plate and a pad distributed between the inclined plate and the force transmission plate. The force transmission plate is arranged parallel to the channel body. One end of the pad is connected to the force transmission plate, and the other end is inclined and extends to the inclined plate and is connected to the inclined plate.

[0009] The present invention is further configured such that the locking plate feeding mechanism is a vibratory plate, and the connection between the inclined plate and the vibratory plate is formed by the placement limit on the bottom side of the inclined plate and the top edge of the vibratory plate. The pad and the force transmission plate are both placed on the inclined plate.

[0010] The present invention is further configured such that the pad includes a first pad and a second pad, and the force transmission plate includes a first force transmission plate, a second force transmission plate, a third force transmission plate, and a fourth force transmission plate. The first and second pads are both located on the inclined plate. The first pad is located near one edge of the inclined plate, and the second pad is located near the other edge of the inclined plate. The first and second force transmission plates are both located on the first pad, and the third and fourth force transmission plates are both located on the second pad. The first, second, third, and fourth force transmission plates are respectively connected to the channel body.

[0011] The present invention is further configured such that the channel body includes a channel groove plate with a locking plate feeding groove and a channel cover plate covering the channel groove plate. The first, second, third and fourth force transmission plates are respectively connected to the channel groove plate to form the vibration force of the locking plate feeding mechanism transmitted by the first, second, third and fourth force transmission plates to the locking plate feeding channel.

[0012] The present invention is further configured such that the locking plate feeding channel also includes a locking plate guide plate disposed on the channel body. The locking plate feeding ports on the channel body are distributed between the locking plate guide plate and the feeding area of the locking plate feeding mechanism. Among the locking plates fed through the feeding area of the locking plate feeding mechanism, the locking plates that do not enter the locking plate feeding port fall back into the locking plate feeding mechanism through the locking plate guide plate.

[0013] The beneficial effects of this utility model are as follows: In addition to the locking plate feeding channel and the locking plate feeding mechanism for vibratory feeding of the locking plates, the fully automatic metal sheet anti-loosening nut riveting machine also includes a tilting mechanism. The tilting mechanism is connected to the channel body and the locking plate feeding mechanism respectively. Thus, during the riveting machine's operation, after the locking plates are fed by the locking plate feeding mechanism, they enter the locking plate feeding channel one by one through the locking plate feeding port on the channel body. Simultaneously, the vibration force of the locking plate feeding mechanism is transmitted to the tilting mechanism, and then from the tilting mechanism to the locking plate feeding channel. This achieves vibratory feeding of the locking plate feeding channel, eliminating the need for a separate vibrator as in existing systems. This also realizes the design of the locking plate tilting feeding mechanism involved in this utility model, which can reduce the design cost of the riveting machine to a certain extent, and also improves the efficiency of vibration transmission compared to the locking plate feeding mechanism. The power of the locking plates is synchronized, which simplifies the control requirements. In addition, because the tilting mechanism is tilted, the locking plate feeding channel can be tilted to a certain extent with the tilting mechanism. Compared with the existing pressing riveting machine whose locking plate feeding channel is horizontal, a slight tilt can prevent blockage at a certain position in the channel (if some of the locked plates fed are burrs or bent, which are of poor quality; if the locking plates in the feeding channel are constantly moving, there is little chance of jamming, but if the front is blocked, the locking plates will vibrate in place, which can easily cause them to get stuck). The tilted feeding method can make the locking plates behind push the locking plates in front and vibrate, thereby clearing the blockage. This improves the smoothness of the locking plate feeding process to a certain extent, ensures fast feeding, and also solves the problem of intermittent adhesion between the channel walls of the locking plate feeding channel during the existing locking plate feeding process.

[0022] like Figure 1-8 As shown, a specific embodiment of this utility model is a locking plate tilting feeding mechanism for a fully automatic metal sheet anti-loosening nut riveting machine, including a locking plate feeding channel 2, a locking plate feeding mechanism 1 for vibrating feeding of locking plate a, and a tilting mechanism 3. The locking plate feeding channel 2 includes a channel body 23, and a locking plate inlet 21 and a locking plate outlet 22 distributed on the channel body 23. The locking plate inlet 21 is distributed on one side of the locking plate feeding mechanism 1, and the locking plate outlet 22 is distributed on one side of the locking plate pushing mechanism on the external riveting machine. The tilting mechanism 3 is connected to the channel body 23 and the locking plate feeding mechanism 1 respectively. Through the tilting mechanism 3, the vibration force of the locking plate feeding mechanism 1 is transmitted to the locking plate feeding channel 2, and the locking plate a is vibrated and accelerated to feed in the locking plate feeding channel 2. The locking plate inlet 21 is a locking plate insertion hole opened on one side facing the locking plate feeding mechanism 1.

[0023] In addition to the locking plate feeding channel 2 for feeding locking plate a and the locking plate feeding mechanism 1 for vibratory feeding of locking plate a, the fully automatic metal sheet anti-loosening nut riveting machine also includes an inclined mechanism 3. The inclined mechanism 3 is connected to the channel body 23 and the locking plate feeding mechanism 1 respectively. Thus, during the riveting machine's operation, after the locking plate a is shaped by the locking plate feeding mechanism 1, it enters the locking plate feeding channel 2 one by one through the locking plate feeding port 21 on the channel body 23. Simultaneously, the vibration force of the locking plate feeding mechanism 1 is transmitted to the inclined mechanism 3, and then from the inclined mechanism 3 to the locking plate feeding channel 2. This achieves vibratory feeding of the locking plate feeding channel 2, eliminating the need for a separate vibrator as in existing systems. This design of the locking plate inclined feeding mechanism, as described in this utility model, reduces the design cost of the riveting machine to a certain extent, and also improves the efficiency of vibration transmission by integrating the power supplied by the locking plate feeding mechanism 1 with the power supplied by the locking plate feeding mechanism 1. The power synchronization of locking piece a simplifies control requirements. Furthermore, since the tilting mechanism 3 is tilted, the locking piece feeding channel 2 can tilt to a certain extent with the tilting mechanism 3. Even compared to the existing riveting machine where the locking piece feeding channel 2 is horizontally fed, a slight tilt can prevent blockage at a certain position in the channel (if some of the fed locking pieces a are burrs or bent, indicating poor quality; if the locking pieces a in the locking piece feeding channel 2 are constantly moving, there is less chance of jamming, but if the front is blocked, the locking pieces a will vibrate in place, making them prone to jamming). The tilted feeding method can cause the rear locking pieces a to squeeze the front locking pieces a and vibrate, thereby clearing the blockage. This improves the smoothness of the locking piece a feeding process to a certain extent, ensuring fast feeding, and also solves the problem of intermittent adhesion between the channel walls of the locking piece feeding channel 2 during the existing locking piece a feeding process.

[0024] like Figure 1-6 As shown, the tilting mechanism 3 includes a tilting plate 33 and a vibration force transmission plate 31. The vibration force transmission plate 31 is located on the tilting plate 33. The tilting plate 33 is connected to the locking plate feeding mechanism 1 and extends to one side of the channel body 23. The design of the vibration force transmission plate 31, which is located on the tilting plate 33, extending to one side of the channel body 23 along with the tilting plate 33 and connected to the channel body 23, allows the vibration force of the locking plate feeding mechanism 1 to be reliably transmitted to the locking plate feeding channel 2 during the force transmission process of the tilting mechanism 3, thereby realizing the reliability of the design of this utility model.

[0025] like Figure 1-6As shown, the vibration force transmission plate 31 includes a force transmission plate 31 and a pad 32 distributed between the inclined plate 33 and the force transmission plate 31. The force transmission plate 31 is arranged parallel to the channel body 23. One end of the pad 32 is connected to the force transmission plate 31, and the other end is inclined and extends to and connects to the inclined plate 33. This design allows the inclined vibration force of the inclined mechanism 3 to be reliably transmitted to the locking plate feeding channel 2, thereby ensuring that the inclined mechanism 3 improves the smoothness of the conveying process of the locking plate a and ensures fast and reliable feeding.

[0026] like Figure 1-6 As shown, the locking plate feeding mechanism 1 is a vibratory plate. The connection between the inclined plate 33 and the vibratory plate is formed by the placement limit on the bottom side 331 of the inclined plate 33 and the edge of the top side 12 of the vibratory plate. The pad block 32 and the force transmission plate 31 are both placed on the inclined plate 33. This scheme can realize the reliable connection between the inclined mechanism 3 and the locking plate feeding mechanism 1, and the inclined mechanism 3 itself can be reliably distributed.

[0027] like Figure 1-6 As shown, the pad 32 includes a first pad 322 and a second pad 321, and the force transmission plate 31 includes a first force transmission plate 311, a second force transmission plate 312, a third force transmission plate 313, and a fourth force transmission plate 314. The first and second pads are both confined to the inclined plate 33. The first pad 322 is near one edge of the inclined plate 33, and the second pad 32 is near the other edge of the inclined plate 33. The first and second force transmission plates are both confined to the first pad 322, and the third and fourth transmission plates are both confined to the second pad 321. The first, second, third, and fourth force transmission plates are respectively connected to the channel body 23. The channel body 23 includes a locking plate feed groove 231. The channel groove plate c, the channel cover plate b covering the channel groove plate c, and the first, second, third, and fourth force transmission plates are respectively connected to the channel groove plate c to form a design that transmits the vibration force of the locking plate feeding mechanism 1 transmitted by the first, second, third, and fourth force transmission plates to the locking plate feeding channel 2. This design allows the pads 32 distributed on the inclined plate 33 to reliably transmit the inclined vibration force to the locking plate feeding channel 2 during the connection with the force transmission plate 31. At the same time, it ensures that during the force transmission process, the locking plate a will jump due to gravity when vibration is involved. By transmitting the force to the channel groove plate c, the vibration of this utility model can be reliably achieved.

[0028] like Figure 1-6As shown, the locking plate feeding channel 2 also includes a locking plate guide plate 4 disposed on the channel body 23. The locking plate feeding ports 21 on the channel body 23 are distributed between the locking plate guide plate 4 and the feeding area 11 of the locking plate feeding mechanism 1. Among the locking plates a fed through the feeding area 11 of the locking plate feeding mechanism 1, the locking plates a that do not enter the locking plate feeding port 21 fall back into the locking plate feeding mechanism 1 through the locking plate guide plate 4. This design makes it less likely that when the locking plate feeding mechanism 1 feeds into the locking plate feeding channel 2, some locking plates a that do not enter the locking plate feeding port 21 will accidentally fall outside the locking plate feeding mechanism 1, thereby further ensuring the reliability of the design of the present invention.
