DETAILED DESCRIPTION OF THE INVENTION

[0009] In order to better understand the purpose, structure and function of the present invention, the following further detailed description of the present invention is made with reference to the accompanying drawings.

[0010] As Figure 1 shown, the present invention provides a device for automatically supplying flange bolts, including a front-end conveying mechanism, a transfer mechanism and a guiding mechanism that are connected in sequence.

[0011] As Figure 1 , Figure 2 shown, the front-end conveying mechanism includes a feeder 1, a conveying chute 2, a sensor 3, a cylinder one 4 and a limit plate 5; the output end of the feeder 1 is connected to the conveying chute 2, the output end of the conveying chute 2 is provided with a sensor 3, the limit plate 5 is arranged above the conveying end of the conveying chute 2 and fixed on the cylinder one 4, and its lifting is controlled by the cylinder one 4.

[0012] The feeder 1 selects a vibrating bowl feeder, and the stored bolts 18 are arranged in the required direction and position by vibration, and the bolts 18 are continuously supplied.

[0013] The conveying chute 2 is used to connect the feeder 1 and the turntable 17 on the servo motor 6, convey the bolts 18 forward in sequence to the turntable 17, and store a certain amount of bolts 18 in front for waiting to be used next time.

[0014] The sensor 3 is used to sense the signal after the bolt 18 arrives, transmit the signal to the PCL, count the PLC counter, and control the cylinder 1 4 to open the limit plate 5, and wait to close the limit plate 5 after the number of passed bolts 18 is sufficient.

[0015] The cylinder 1 4 is used to obtain the PLC signal and start the telescopic function, so as to control the opening and closing of the limit plate 5.

[0016] The limit plate 5 prevents the bolts 18 from mistakenly entering the limit holes 171 of the turntable 17 when there are too many bolts 18, and prevents damage to the equipment.

[0017] As Figure 3 shown, a long strip notch 21 is provided in the middle of the conveying chute 2 for lapping the bolts 18.

[0018] As Figure 1 、 Figure 3 shown, the transfer mechanism includes a servo motor 6, a turntable 17, a cylinder 2 7, a cylinder 3 8, a cylinder 4 9, a positioning plate 10, a conveying pipe seat 11 and a plurality of conveying pipes 12; the turntable 17 is installed on the output shaft of the servo motor 6, and the turntable 17 is horizontally connected to the rear side of the conveying chute 2, the cylinder 2 7 is connected to the servo motor 6 and is used to drive the servo motor 6 and the turntable 17 to move up and down, the cylinder 3 8 is connected to the cylinder 2 7 and is used to drive the cylinder 2 7, the servo motor 6 and the turntable 17 to move back and forth, a plurality of the conveying pipes 12 are installed on the positioning plate 10 through the conveying pipe seat 11 and are communicated with the middle hole 101 of the positioning plate 10, and the cylinder 4 9 is connected to the positioning plate 10 and is used to drive the positioning plate 10 to move back and forth.

[0019] A circle of limit holes 171 is provided on the outer edge of the turntable 17, and the limit holes 171 are composed of limit oblong holes 1711 and limit circular holes 1712. The diameter of the limit oblong holes 1711 is smaller than the head diameter of the bolt 18 and can support the bolts 18 falling from the conveying chute 2. The diameter of the limit circular holes 1712 is larger than the head diameter of the bolt 18, so that when the positioning plate 10 moves horizontally to drive the bolt 18 inserted into the middle hole 101 to move from the limit oblong hole 1711 to the limit circular hole 1712 relatively, it can fall.

[0020] A plurality of limit oblong holes 1711 are arranged in a circumferential array, and the corresponding limit circular holes 1712 are arranged behind the limit oblong holes 1711.

[0021] The servo motor 6 precisely controls the turntable 17 to cooperate with the conveying chute 2 at a certain position and angle to perform the operation of taking out 22 bolts 18.

[0022] The second cylinder 7 is used to lift or lower the servo motor 6 and the turntable 17, and its purpose is to transfer the 22 bolts 18 in the limit holes 171 on the turntable 17.

[0023] The third cylinder 8 is used to horizontally move the servo motor 6 and the turntable 17 to the position of the positioning plate 10.

[0024] The fourth cylinder 9 is used to slide the 22 bolts 18 with fixed positions from the turntable 17 into the connected conveying pipe 12 on the positioning plate 10, so that the bolts 18 can slide smoothly.

[0025] The positioning plate 10 is used to connect 22 conveying pipes 12 and plays a role in positioning and guiding.

[0026] The conveying pipe seat 11 is used to connect the conveying pipes 12 for conveying bolts 18. The conveying pipe 12 supplies the bolts 18 to the tightening pre-installation device, the 3D printing guiding device 13.

[0027] As Figure 1 、 Figure 4 、 Figure 5 shown, the guiding mechanism includes a 3D printing guiding device 13, a fifth cylinder 14, a transverse moving cylinder 15 and a 3D printing positioning device 16; the 3D printing guiding device 13 is supported by the fifth cylinder 14, and a plurality of guiding holes 131 are opened on the 3D printing guiding device 13, and the plurality of guiding holes 131 are connected to the plurality of conveying pipes 12 in a one-to-one correspondence. The 3D printing positioning device 16 is arranged below the 3D printing guiding device 13 and installed on the transverse moving cylinder 15, and is driven by the transverse moving cylinder 15 to move horizontally. A plurality of positioning holes 161 are opened on the 3D printing positioning device 16, and the plurality of positioning holes 161 are connected to the plurality of guiding holes 131 in a one-to-one correspondence.

[0028] As Figure 4 shown, the 3D printing guiding device 13 is a plate-like structure as a whole, and a plurality of guiding holes 131 are opened on the plate-like structure, and guiding cylinders 132 are arranged on the guiding holes 131 to facilitate connection with the conveying pipes 12.

[0029] As Figure 5As shown, the 3D printing positioning device 16 is a plate-like structure as a whole, and a plurality of positioning holes 161 are formed in the plate-like structure. Each positioning hole 161 is composed of a positioning oblong hole 1611 and a positioning circular hole 1612. The diameter of the positioning oblong hole 1611 is smaller than the head of the bolt 18, and the head of the bolt 18 that can be supported by the 3D printing guiding device 13 can fall. The diameter of the positioning circular hole 1612 is larger than the head of the bolt 18. When the 3D printing guiding device 13 moves horizontally, when the bolt 18 moves relatively from the positioning oblong hole 1611 to the positioning circular hole 1612, it can fall.

[0030] The 3D printing guiding device 13 is used to accurately position the bolts 18 conveyed by the conveying pipe 12 again, so that each bolt 18 can be aligned with the bolt holes of the valve body.

[0031] The fifth cylinder 14 is used to fix and support the feeding 3D printing guiding device 13 and extend into the valve body pin hole for the equipment to automatically tighten.

[0032] The transverse movement cylinder 15 is connected to the 3D printing positioning device 16 to enable it to move left and right, and the purpose is to withdraw the 3D printing positioning device 16 sent into the valve body nail hole.

[0033] The 3D printing positioning device 16 is used to smoothly and accurately place the 22 bolts 18 in the 3D printing special guiding device into the valve body.

[0034] Working process: After the valve body is assembled, bolt 18 is placed into feeder 1. Through the vibration arrangement of feeder 1, it enters conveying chute 2. Bolt 18 overlaps on the long notch 21 of conveying chute 2 and slides along it. When bolt 18 passes through, after sensor 3 senses bolt 18, it triggers the PLC to send a signal to the solenoid valve, causing cylinder 1 4 to open and start counting (22 times). Then cylinder 1 4 is closed. At the same time, the PLC drives servo motor 6 to drive turntable 17 to rotate to the corresponding position to receive bolt 18 that falls from long notch 21. After servo motor 6 rotates one week, the limit holes 171 on turntable 17 are filled with bolts 18. Then the PLC triggers cylinder 2 7 to lift. After reaching the position, it triggers cylinder 3 8 to pull back, moving turntable 17 to the upper end of positioning plate 10. At this time, bolt 18 corresponds one by one to the middle hole 101 of the lower positioning plate 10. After cylinder 3 8 extends and retracts to the position, cylinder 2 7 extends, causing bolt 18 to be inserted into the corresponding middle hole 101. Then cylinder 4 9 acts, and positioning plate 10 translates, driving the bolt 18 inside it to move, so that bolt 18 falls from turntable 17 into the corresponding middle hole 101 of positioning plate 10 and slides down along 22 conveying pipes 12 to 3D printing guiding device 13. All the above actions return to the origin and wait for the next operation. Then it falls onto 3D printing positioning device 16. Then cylinder 5 14 drives 3D printing positioning device 16 to probe into the valve body bolt hole. Then the transverse movement cylinder 15 drives 3D printing positioning device 16 to translate, so that bolt 18 falls from positioning hole 161 into the valve body bolt hole for the tightening machine to tighten. Then 3D printing positioning device 16 is withdrawn and returns to the original position, completing one working cycle. After the turntable 17 on the production line is triggered again, the next working cycle is carried out.
