Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figure 1-8 , the present invention provides a technical solution: a short-distance nut column swinging feeding device, which is composed of a base 100, a swinging blanking mechanism 200 and a pneumatic adsorption pushing mechanism 500. A turning fixture assembly 110 is installed on the top of one end of the base 100, and a turning tool assembly 120 is installed at the other end of the base 100;

[0025] The swinging blanking mechanism 200 is located on one side of the turning fixture assembly 110 and is fixedly installed with the base 100, and the swinging blanking mechanism 200 is connected with a vibrating bowl feeder 400 for placing short-distance nut columns through a receiving plate 300;

[0026] The pneumatic adsorption pushing mechanism 500 is installed on the top of one side of the base 100 through a connecting frame 510, and the pneumatic adsorption pushing mechanism 500 adsorbs the short-distance nut columns sent down by the swinging blanking mechanism 200 and sends them into the turning fixture assembly 110.

[0027] Specifically, the provided base 100 serves to support and fix various components. The provided turning fixture assembly 110 is used to clamp and fix the short-distance nut column to be machined. The provided turning tool assembly 120 is used to perform cutting machining on the short-distance nut column. The swing feeding mechanism 200 efficiently and continuously feeds the short-distance nut column. The provided vibrating bowl 400 is connected to the swing feeding mechanism 200 through the receiving plate 300. The vibrating bowl 400 is used to store and vibrate and arrange the short-distance nut columns so that they can smoothly enter the guide chute 260.

[0028] The provided pneumatic adsorption and pushing mechanism 500 uses negative pressure adsorption technology. After adsorbing the short-distance nut column sent down by the swing feeding mechanism 200, it accurately sends it into the turning fixture assembly 110, reducing the sliding and offset of the nut during the transmission process.

[0029] When machining the short-distance nut column, the vibrating bowl 400 is driven by a motor to generate high-frequency vibration, causing the short-distance nut columns to be arranged and move within the vibrating bowl 400. The short-distance nut columns enter the receiving plate 300 after being vibrated and arranged in the vibrating bowl 400, and then enter the guide chute 260 under the action of gravity. The guide chute 260 is inclined. By the combined action of gravity and vibration force, the short-distance nut columns smoothly slide into the feeding port 2110 of the swing feeding cam block 290. Then, the short-distance nut column sent down from the feeding port 2110 generates a negative pressure effect through the hollow pushing rod 580 of the pneumatic adsorption and pushing mechanism 500, and firmly adsorbs the short-distance nut column by using the negative pressure suction nozzle 5110, avoiding the sliding or offset of the nut during the adsorption process. Then, the short-distance nut column adsorbed on the negative pressure suction nozzle 5110 is pushed into the turning fixture assembly 110, and finally, the turning tool assembly 120 performs turning machining on the short-distance nut column clamped by the turning fixture assembly 110.

[0030] In this embodiment, the turning tool assembly 120 includes a first mounting plate 121 fixedly installed at the top of the other end of the base 100. The top of the first mounting plate 121 is slidably connected to a tool holder mounting seat 123 through a first linear slide rail 122. A first ball screw linear module 124 is also installed at the top of the first mounting plate 121 between the two first linear slide rails 122. The sliding plate of the first ball screw linear module 124 is fixedly connected to the bottom of the tool holder mounting seat 123. A cutting tool 125 is installed at the top of the tool holder mounting seat 123.

[0031] Specifically, when the short-distance nut column is accurately fed into the turning fixture assembly 110 by the pneumatic adsorption feeding mechanism 500, the turning fixture assembly 110 firmly fixes the short-distance nut column and drives it to rotate. The external PLC controller controls the first ball screw linear module 124 to start working. The motor drives the ball screw to rotate, thereby driving the sliding plate to perform a stable linear motion along the first linear slide rail 122. The tool holder mounting seat 123 also moves accordingly, driving the cutting tool 125 mounted on its top to approach or move away from the short-distance nut column fixed in the turning fixture assembly 110, and using the cutting tool 125 to perform cutting processing on the short-distance nut column.

[0032] To prevent dust or dirt from damaging the first linear slide rail 122 and the first ball screw linear module 124, a protective cover is also installed outside the first mounting plate 121.

[0033] In this embodiment, the swing feeding mechanism 200 includes a support frame 210 fixedly installed at the top of one end of the base 100. At one end of the top of the support frame 210, a cam-shaped first shaft support seat 220 is installed. Inside the groove on one side of the top of the first shaft support seat 220, a first arc-shaped side plate 230 is fixedly installed. On the other side of the top of the first shaft support seat 220, a second arc-shaped side plate 240 is fixedly connected. At the top of the first shaft support seat 220, a guide seat 250 that fits the first arc-shaped side plate 230 and the second arc-shaped side plate 240 is fixedly connected. On the top of the guide seat 250, a guide groove 260 that is opposite to the position of the receiving plate 300 and is inclined is provided. On one side of the first shaft support seat 220, a second shaft support seat 270 fixedly installed at the top of the support frame 210 is provided. A swing feeding cam block 290 is connected between the second shaft support seat 270 and the first shaft support seat 220 through an inserted and connected rotating shaft 280. At the top of the swing feeding cam block 290, a feeding port 2110 that is opposite to one end of the guide groove 260 is provided. The swing feeding mechanism 200 also includes a first cylinder mounting seat 2111 installed at the other end of the top of the support frame 210. Inside the first cylinder mounting seat 2111, a first cylinder 2112 is installed. The telescopic end of the first cylinder 2112 is connected to a rack 2113. The bottom of the rack 2113 is slidably connected to a U-shaped seat 2114 installed at the top of the support frame 210. The rack 2113 is meshed with a gear 2115. The gear 2115 is installed at one end of the rotating shaft 280. At one end of the swing feeding cam block 290, a limit cam block 2116 is provided. One end of the limit cam block 2116 is fixedly installed with the top of the support frame 210 through a connecting rod 2117.

[0034] Specifically, the vibrating disk 400 is driven by a motor to generate high-frequency vibrations, causing the short-distance nut columns to be arranged and moved within the vibrating disk. The short-distance nut columns enter the receiving plate 300 through the vibration arrangement of the vibrating disk 400 and then enter the guiding chute 260. Finally, through the action of gravity and vibration, the short-distance nut columns slide to the discharge opening 2110 of the swinging discharge cam block 290. Then, the first cylinder 2112 drives the rack 2113 to move through telescopic motion. The rack 2113 meshes with the gear 2115, driving the gear 2115 to rotate, and thus driving the swinging discharge cam block 290 to swing through the rotating shaft 280. During the swinging process of the swinging discharge cam block 290, the short-distance nuts in the guiding chute 260 are smoothly discharged through the discharge opening 2110. The provided limiting cam block 2116 can accurately position the swinging discharge cam block 290 during the swinging process, avoiding excessive swinging or insufficient swinging, thereby ensuring the stability and continuity of the discharging process. To ensure the stability of the short-distance nut columns entering the guiding chute 260 and the discharge opening 2110, a protective baffle 2118 is detachably installed on the top of the guiding seat 250.

[0035] In this embodiment, the pneumatic adsorption and pushing mechanism 500 includes a second mounting plate 520 installed on the top of the connecting frame 510. One side of the top of the second mounting plate 520 is slidably connected to a connecting plate 540 through a second linear slide rail 530. The other side of the top of the second mounting plate 520 is installed with a second ball screw linear module 521. The sliding plate of the second ball screw linear module 521 is fixedly connected to the connecting plate 540. One end of the connecting plate 540 is fixedly connected to a receiving seat 550. The surface of the receiving seat 550 is provided with a U-shaped receiving groove 551. One end outside of the connecting plate 540 is installed with a second cylinder 570 through a second cylinder mounting seat 560. One end of the second cylinder 570 is connected to a hollow pushing rod 580. The top of the hollow pushing rod 580 is provided with a negative pressure port 590 for connecting an air pipe. One end of the hollow pushing rod 580 is slidably placed in the U-shaped receiving groove 551 and is threadedly connected to a negative pressure suction nozzle 5110.

[0036] Specifically, when the short-distance nut columns are sent down by the swinging discharging mechanism 200, the second ball screw linear module 521 is driven by a motor, and its sliding plate drives the connecting plate 540 to move along the second linear slide rail 530, aligning the hollow pushing rod 580 with the discharge opening 2110. Then, the second cylinder 570 starts to work, driving the hollow pushing rod 580 to move forward through its telescopic motion, bringing the negative pressure suction nozzle 5110 close to the short-distance nut columns. At this time, after the negative pressure port 590 is connected to negative pressure, negative pressure is generated, and the negative pressure suction nozzle 5110 firmly adsorbs the short-distance nut columns through the negative pressure adsorption force at its opening. The second cylinder 570 retracts, causing the short-distance nut columns to enter the U-shaped receiving groove 551. At the same time, the negative pressure suction effect can effectively improve the stability of the short-distance nut columns during transportation, reduce the sliding or deviation of the nuts, and improve the feeding accuracy.

[0037] Then, driven by the second ball screw linear module 521, the U-shaped material receiving groove 551 is moved to the turning fixture assembly 110 and aligned with the fixture. Then, the second cylinder 570 extends to push the short-distance nut column into the fixture. At this time, the negative pressure port 590 stops accessing negative pressure. Then, driven by the second ball screw linear module 521, the U-shaped material receiving groove 551 is moved away from the fixture to prepare for the turning process.

[0038] To prevent dust or dirt from damaging the second linear slide rail 530 and the second ball screw linear module 521, a protective cover is also installed outside the second mounting plate 520.

[0039] In this embodiment, the number of openings of the negative pressure suction nozzle 5110 is at least one. When there are multiple openings, the multiple openings are distributed in one or more of a linear distribution, a cross-shaped distribution, a triangular distribution, a quadrilateral distribution, or a polygonal distribution.

[0040] Specifically, when there are multiple openings in the negative pressure suction nozzle 5110, the distribution mode of the openings is optimized according to the actual shape of the short-distance nut column. For example, the linear distribution is suitable for long-strip nuts, the cross-shaped distribution is suitable for square nuts, and the triangular and quadrilateral distributions are suitable for polygonal or irregularly shaped nuts. The opening design can flexibly adapt to different types of nuts to ensure that each nut can be firmly and stably attached to the negative pressure suction nozzle 5110 when adsorbed.

[0041] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art. 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 perform equivalent replacements for some of the technical features.
