The input end of the feeding motor 86 is electrically connected with the output end of the single-chip microcomputer 11.

[0030] The working principle of the utility model is as follows:

[0031] When the automatic feeding device is needed, the position of the fillet positioning block 37 can be adjusted according to the specifications of the parts to be processed. At this time, the single-chip microcomputer 11 can be adjusted to stabilize the operation of the motor 4, and the output shaft of the motor 4 can be adjusted to rotate forward and backward, thereby driving the lead screw 33 to rotate forward and backward, and then driving the sliding block 34 to adjust the left and right positions in the sliding groove 32, and then adjusting the position of the positioning and mounting block 35 to adjust the position, and then adjusting the transverse position of the fillet positioning block 37 to adapt to different specifications of the parts to be processed for tapping work. The tapping raw materials can be poured into the inside of the vibrating feed tray 10. At this time, the vibrating feed tray 10 will transport the unprocessed parts according to the specified travel trajectory, and when the unprocessed parts are transported to the front of the feed channel 7, they will be blocked by the front side wall of the feed channel 7. Only one unprocessed part can enter the feed channel 7 at a time.

[0032] At this time, the external air pump can be adjusted to drive the feed cylinder 12 to operate, and the telescopic end of the feed cylinder 12 can be adjusted to perform one telescopic operation, thereby driving the fillet block 9 to move back and forth from right to left once, and pushing the unprocessed parts in the feed channel 7 into the inside of the lower limit clamping frame 83 on the right side. At this time, the single-chip microcomputer 11 can be adjusted, and the feed motor 86 can be operated to rotate counterclockwise by 90 degrees once, thereby rotating the unprocessed parts on the right side counterclockwise by 90 degrees around the middle part of the disc-shaped feed table 1. During this period, the inclined feed tray 81 is inclined, and the upper limit clamping frame 82 cooperates with the lower limit clamping frame 83 to slowly clamp the unprocessed parts up and down during the counterclockwise rotation of the inclined feed tray 81 by 90 degrees. At this time, the single-chip microcomputer 11 can be adjusted, and the feed motor 86 can be operated to rotate counterclockwise by 90 degrees again, thereby moving the unprocessed parts on the rear side to the left side. At this time, the upper limit clamping frame 82 cooperates with the lower limit clamping frame 83 to tightly clamp the unprocessed parts up and down, and the unprocessed parts are affected by the elastic force of the spring 39. During this period, the telescopic rod 36 will slowly contract;

[0033] When the unprocessed parts move to the leftmost side of the arc-shaped pusher plate 31, the telescopic rod 36 contracts to the shortest, the left side of the fillet positioning block 37 tightly presses the right side of the unprocessed parts from the left side, and the inner arc surface of the disc-shaped feed table 1 tightly clamps the left side of the unprocessed parts. At this time, the external tapping machine can be adjusted to perform tapping work on the upper surface of the part. The water generated by tapping leaks out through the liquid leakage hole 6. The processed parts are rotated again through the feed tray 8, and during the rotation process, the parts in the lower limit clamping frame 83 are ejected through the inclined side arc surface of the arc-shaped pusher plate 31, and the parts fall. During this period, the parts are affected by the elastic force of the spring 39, and the fillet positioning block 37 is reset. At this time, the above operation can be continuously repeated to complete the continuous tapping feeding operation.

[0034] It is worth noting that the single-chip microcomputer 11 disclosed in the above embodiment is specifically S7-200, and the stable motor 4, the feeding motor 86, the height adjusting cylinder, the pushing feeding cylinder 12 and the feeding disc 10 can be freely configured according to the actual application scene, the stable motor 4 is recommended to be selected from an STM28 series stepping motor, the feeding motor 86 is recommended to be selected from a GV series speed reducer motor, the height adjusting cylinder is recommended to be selected from an NDC series standard cylinder, the pushing feeding cylinder 12 is recommended to be selected from an SDA series thin cylinder, and the feeding disc 10 is recommended to be selected from a cnc hardware feeding vibration disc, and the single-chip microcomputer 11 controls the stable motor 4, the feeding motor 86 and the feeding disc 10 to work by using a method commonly used in the prior art.
