[0006] By adopting the above technical scheme, the blanks are fed into the material selection tray and then tested by the ultrasonic flaw detector to automatically classify the defective blanks and the intact blanks. Then the first discharging guide rail selects the materials through the switch device to complete the automatic classification of the blanks.

[0007] Furthermore, the second discharging guide track is used to output defect-free blanks, and defective blanks are discharged along the first discharging guide track.

DETAILED DESCRIPTION

[0025] A feeding mechanism of a thread rolling machine comprises a feeding guide rail 1 and an ultrasonic flaw detector 2. One end of the feeding guide rail 1 is connected to the discharge port of a vibration plate. The blank enters the feeding guide rail 1 from the vibration plate. The feeding guide rail 1 extends downward horizontally, so that the blank moves along the feeding guide rail 1 by gravity.

[0026] A feeding mechanism of a thread rolling machine also includes a material selection wheel, a first discharging guide rail 6, a second discharging guide rail 7, a stepping motor 8, a limit plate 17, and an opening and closing device.

[0027] The material selection wheel is divided into an inner wheel 3 and an outer wheel 4. A bracket 5 is provided under the outer wheel 4 to install the outer wheel 4 at a desired position. The outer wheel 4 is also inclined horizontally, and the inclination angle is the same as that of the feed guide rail 1. The inner wheel 3 is rotatably installed in the outer wheel 4.

[0028] The outer surface of the inner wheel disc 3 is provided with a groove 9 just for placing the blank, and the outer wheel disc 4 is provided with a notch corresponding to the groove 9 of the inner wheel disc 3.

[0029] Preferably, there are four grooves 9 on the inner wheel disc 3, and the four notches are evenly distributed on the inner wheel disc 3. The notch of the feed guide rail 1, the notch of the first discharging guide rail 6, and the notch of the second discharging guide rail 7 are arranged clockwise around the outer wheel disc 4, so that the stepper motor can evenly deliver the blank to the corresponding position each time it rotates 90 degrees.

[0030] The stepper motor 8 is arranged on the bracket 5, and the output shaft of the motor is connected to the central axis of the inner wheel disc 3, driving the inner wheel disc 3 to rotate clockwise, and resting for 0.5 seconds every time it rotates 90 degrees.

[0031] The end of the feed guide rail 1 away from the vibration plate is connected to the first notch of the outer wheel plate 4, and the blank is fed into the groove 9 of the inner wheel plate 3 through the first notch 10. The blank is driven by the inner wheel plate 3 to rotate in the outer wheel plate 4.

[0032] The ultrasonic flaw detector 2 is fixedly arranged at the second notch of the outer wheel disc 4 to detect the rotating blank.

[0033] One end of the first discharge guide rail 6 and the second discharge guide rail 7 are respectively connected to the third and fourth notches 13 of the outer wheel disc 4, and the first discharge guide rail 6 and the second discharge guide rail 7 extend horizontally downward, and the blank can slide along the first discharge guide rail 6 and the second discharge guide rail 7 by gravity.

[0034] Optionally, an oil tank 14 is provided on the outside of the outer guide rail, and the installation position of the oil tank 14 is higher than the outer guide rail. The outer wheel disc 4 is provided with a channel 15 for lubricating oil to pass through. A layer of sponge pad 16 is provided on the surface around the channel 15 on the inner side of the outer wheel disc 4. The lubricating oil flows from the oil tank 14 into the sponge pad 16 through the channel 15. When the blank passes through, the sponge pad 16 is squeezed to evenly spread the lubricating oil on the blank.

[0035] The opening and closing device is installed on the first discharge guide rail 6, and the limit plate 17 is connected to the opening and closing device. The opening and closing device is responsible for receiving the signal of the ultrasonic flaw detector 2, and then controlling the limit plate 17 to open or close the outlet of the first discharge guide rail 6. When the limit plate 17 is opened, the material slides out from the first discharge guide rail 6. When the limit plate 17 is closed, the material cannot pass through the first discharge guide rail 6, and the blank continues to move along the inner side of the outer wheel disc 4.

[0036] Optionally, the opening and closing device includes a servo motor 18, a turntable 21, and a crank 19. The servo motor 18 is fixedly mounted on the first discharging guide rail 6. The turntable 21 is mounted on the output shaft of the servo motor 18. One end of the crank 19 is connected to the turntable 21, and the other end is connected to the limit plate 17. A slide rail 20 is provided above the first discharging guide rail 6. The limit plate 17 is slidably connected to the slide rail 20. When the motor rotates, the limit plate 17 is driven to slide along the slide rail 20 through the cooperation of the turntable 21 and the crank 19, thereby realizing the opening and closing of the outlet of the first discharging guide rail 6.

[0037] Optionally, when the blank is a defective blank, after being inspected by the ultrasonic flaw detector 2, when the defective blank passes through the third notch 12, the opening and closing device drives the limit plate 17 to open, and the defective blank slides out along the first discharging guide rail 6. The second discharging guide rail 7 is used to output defect-free blanks, and the defective blank is discharged along the first discharging guide rail 6.

[0038] A waste box 22 is provided at one end of the first discharging guide rail 6 away from the outer wheel disc 4 , and the defective blanks are selected and slide along the first discharging guide rail 6 into the waste box 22 .

[0039] The end of the second discharge guide rail 7 away from the outer wheel disc 4 is connected to the thread rolling machine body to feed the intact blank into the thread rolling machine for processing.

[0040] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
