Description

Technical Field

[0001] The utility model discloses an automatic feeding mechanism for pressure riveted nuts, and relates to the technical field of rotary riveting machine processing. Background Art

[0002] The feeding system of a riveting machine is a critical component in ensuring efficient and precise operation of a riveting production line. Its primary task is to automatically deliver rivets or riveting material to the riveting machine's work area, enabling efficient and accurate riveting. The self-clinching nut feeding system is responsible for precisely delivering the nuts to the riveting position, ensuring an efficient and accurate riveting process. Using a vibrating plate feeder is ideal for high-efficiency production and can handle large quantities of nuts.

[0003] In the vibrating plate rivet nut feeding mechanism, when the loading speed of the vibrating plate is greater than the feeding speed, workpieces will be accumulated in the mechanism, causing material jamming, resulting in reduced work efficiency. Therefore, it is necessary to provide an automatic feeding mechanism for rivet nuts to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic feeding mechanism for self-clinching nuts, so as to achieve the effect of accurately feeding the self-clinching nuts while they are stored in the mechanism during feeding.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic feeding mechanism for self-clinching nuts, including a feed port, characterized in that: a dividing mechanism is installed on the feed port, a misalignment mechanism is installed in the dividing mechanism, an air blowing conveying device is provided on the misalignment mechanism, a conveying path for conveying self-clinching nuts is installed on the misalignment mechanism, a pushing mechanism is installed on the conveying path for pushing the self-clinching nuts out of the conveying path, and a workbench is installed on the pushing mechanism; the dividing mechanism includes a dividing plate, a dividing port is provided on the dividing plate for holding the self-clinching nuts, and a limiting plate is provided on the outer surface of the dividing plate for limiting the self-clinching nuts in the dividing port; the misalignment mechanism includes a misalignment port for conveying the self-clinching nuts in the dividing port; the pushing mechanism includes a pushing rod for pushing the self-clinching nuts transmitted from the conveying path into the workbench.

[0006] Preferably, the distribution plate is driven by a motor, and the distribution openings are arranged in several groups.

[0007] Preferably, an arc edge is provided on one side of the material distribution opening, and an arc opening is provided inside the material distribution opening.

[0008] Preferably, a limiting card hole is provided on the material distribution plate, and the limiting card holes are provided in several groups and are evenly distributed at the material distribution port. A limiting hole is provided below the limiting card hole, and a spring is installed in the limiting hole. A limiting bead is installed on the spring, and the limiting bead is slidably connected to the limiting hole.

[0009] Preferably, the material error mechanism is driven by a motor.

[0010] Preferably, a bayonet is installed in the pushing mechanism, and a spring is provided below the bayonet.

[0011] Compared with the prior art, the beneficial effect of the present invention is that the distribution plate is driven by a motor to rotate, and the rivet nuts fed from the feed port enter the distribution plate, and are then received by the distribution port set in the distribution plate, and are fed into the material error mechanism through the rotation of the distribution plate. The setting of the limit plate limits the position of the rivet nuts in the distribution port during movement, and does not separate from the distribution port due to the rotation of the classification plate, so that the rivet nuts are stored in the distribution plate during feeding, and are fed accurately, to prevent the accumulation of workpieces in the mechanism and the occurrence of material jams when the loading speed of the vibration plate is greater than the feeding speed. At the same time, the setting of the bayonet ensures that the processing of a single rivet nut is not affected by the rivet nuts stored on the transmission path, thereby improving the processing accuracy and efficiency and making the entire feeding mechanism structure stable.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Specific implementation cases:

[0018] like Figure 1As shown, an automatic feeding mechanism for self-clinching nuts includes a feed port 1, a material dividing mechanism 2 is installed on the feed port 1, a material error mechanism 3 is installed in the material dividing mechanism 2, an air blowing conveying device (not shown in the figure) is provided on the material error mechanism 3, a conveying path 4 is installed on the material error mechanism 3 for conveying self-clinching nuts, a pushing mechanism 5 is installed on the conveying path 4 for pushing the self-clinching nuts out of the conveying path 4, and a workbench 53 is installed on the pushing mechanism 5;

[0019] When the mechanism is working, the vibration plate connected to the feed port 1 feeds the self-clinching nut into it, and the self-clinching nut then enters the material distribution mechanism 2 through the feed port 1, and then the material dislocation mechanism 3 performs the material distribution on the self-clinching nut, and the air blowing conveying device blows the self-clinching nut into the conveying path 4, and the conveying path 4 sends the self-clinching nut into the pushing mechanism 5, and then the pushing mechanism 5 sends the self-clinching nut to the workbench 53, so that the riveting operation of the fed self-clinching nut is performed on the workbench 53;

[0020] The material distribution mechanism 2 includes a material distribution plate 21, which is driven by a motor. The material distribution plate 21 is provided with a material distribution opening 211 for receiving the self-clinching nuts. The outer surface of the material distribution plate 21 is provided with a limit plate 22 for limiting the self-clinching nuts in the material distribution opening 211. The material distribution opening 211 is provided in several groups.

[0021] When the material distribution mechanism 2 is working, the motor drives the distribution plate 21 to rotate, and the self-clinching nuts fed from the feed port 1 enter the distribution plate 21, and are then received by the distribution port 211 provided in the distribution plate 21. After the distribution plate 21 rotates, the self-clinching nuts are fed into the material discharging mechanism. The setting of the limiting plate 22 limits the position of the self-clinching nuts in the distribution port 211 during movement, and prevents them from leaving the distribution port 211 due to the rotation of the distribution plate 21.

[0022] When the rivet nut is received at the distribution opening 211, it may be difficult for the rivet nut to enter the distribution opening 211 due to the rotation of the distribution plate 21. Therefore, an arc edge 214 is provided on one side of the distribution opening 211, and an arc opening 215 is provided inside the distribution opening 211.

[0023] The arc edge 214 has a large rounded corner at one end, so that the rivet nut will move along the arc surface of the arc edge 214 to the arc opening 215. The interior of the arc opening 215 is a circular arc surface, which is convenient for receiving the rivet nut.

[0024] When the distribution plate 21 distributes and stores the rivet nuts, there will be an angular deviation when they are transported to the wrong material port 31. Therefore, a limit card hole 212 is provided on the distribution plate 21. The limit card holes 212 are provided in several groups and are evenly distributed at the position of the distribution port 211. A limit hole (not marked in the figure) is provided below the limit card hole 212. A spring (not marked in the figure) is installed in the limit hole. A limit bead 213 is installed on the spring. The limit bead 213 is slidably connected to the limit hole.

[0025] When the distribution plate 21 is rotated by the motor, the bottom surface of the distribution plate 21 presses the limiting bead 213 into the limiting hole. When the limiting clamping hole 212 in the distribution plate 21 rotates to above the limiting hole, the limiting bead 213 is clamped into the limiting clamping hole 212, which defines the position of the distribution port 211, making it easier for the blanking mechanism 3 to deliver the rivet nut into the conveying pipe.

[0026] The self-clinching nut is fed into the blanking mechanism 3 by an air suction device, which is installed above the material error mechanism 3. The self-clinching nut is sucked into the material error mechanism 3 and the conveying path 4 by air suction. The air blowing device is a prior art and its specific working principle will not be described in detail.

[0027] The material error mechanism 3 is provided with a material error port 31, and the driving mode of the material error mechanism 3 is motor-driven. The material error port 31 is used to convey the medium pressure rivet nut of the material distribution port 211. The material error mechanism 3 can move repeatedly under the drive of the motor, and the material error port 31 can move repeatedly to intermittently feed the pressure rivet nut. The working principle is the existing technology and will not be described in detail here.

[0028] The pushing mechanism 5 includes a pushing rod 51, which is used to push the rivet nut transmitted from the delivery pipe into the workbench 53. The pushing mechanism 5 is equipped with a bayonet 52, and a spring is provided below the bayonet 52.

[0029] The push rod 51 is driven by a motor to repeatedly move and push the rivet nut. When the rivet nut contacts the latch 52, the latch 52 is pressed down until the push rod 51 pushes the rivet nut out of the latch 52 and sends it to the workbench 53. The push rod 51 moves backward and leaves the latch 52. After that, the latch 52 pops up, restricting the next rivet nut from entering the workbench 53. When the rivet nut on the workbench 53 is processed, the push rod 51 sends the next rivet nut to the workbench 53.

[0030] In summary, the distribution plate 21 is driven by the motor to rotate, and the rivet nuts fed from the feed port 1 enter the distribution plate 21, and are then received by the distribution port 211 set in the distribution plate 21. After the distribution plate 21 rotates, they are fed into the material error mechanism. The setting of the limit plate 22 limits the position of the rivet nuts in the distribution port 211 during movement, and does not separate from the distribution port 211 due to the rotation of the distribution plate 21, so that the rivet nuts can be stored in the distribution plate 21 during feeding, and can be fed accurately, to prevent the accumulation of workpieces in the mechanism and the occurrence of material jams when the loading speed of the vibration plate is greater than the feeding speed. At the same time, the setting of the bayonet 52 ensures that a single rivet nut is not affected by the rivet nuts stored on the conveyor 4 during processing, thereby improving the processing accuracy and efficiency and making the entire feeding mechanism structure stable.

[0031] The above description is merely a preferred embodiment of the present application. The scope of protection of the present application is not limited to the above embodiment. All technical solutions based on this concept fall within the scope of protection of the present application. It should be noted that for those skilled in the art, improvements and modifications that do not depart from the principles of the present application should also be considered within the scope of protection of the present application.
