Detailed Description

Example 1

Referring to fig. 1-2, in the present embodiment, a tapping machine feeding mechanism with a guiding structure includes a base 10 and a supporting plate 20, wherein a positioning slot 11 is defined on the base 10, guiding plates 13 are disposed on two side walls of the positioning slot 11, and the guiding plates 13 have guiding surfaces 14 arranged in an inclined manner; the backup pad 20 is located the below of constant head tank 11, is equipped with push pedal 21 on the backup pad 20, and push pedal 21 is connected with the cylinder 22 transmission that sets up in constant head tank 11, and push pedal 21 can pass from the bottom of the feed bin 15 that disposes on base 10, simultaneously, push pedal 21 can pass between two deflector 13.

According to the embodiment, the existing feeding mechanism is optimized and improved, the guide plate 13 is additionally arranged, nuts can be guided to freely fall after moving upwards by a certain height along the guide surface 14, the nuts can be limited to reversely slide, the success rate of withdrawing the nuts after tapping is finished is improved, the supporting plate 20 matched with the design moves synchronously along with the push plate 21, and one nut at the lowest part of the storage bin 15 can be driven to move towards the guide plate 13 and supported by the nuts in the tapping process.

In this embodiment, alternatively, the positioning groove 11 extends along the longitudinal direction of the base 10 as a whole, the end of the positioning groove 11 is provided with a limiting groove 12 adapted to a nut, and the nut completes tapping in the space between the guide plate 13 and the limiting groove 12.

In addition, the guide plates 13 are symmetrically arranged on the side wall of the positioning groove 11, the lower end of the guide plates 13 is flush with the bottom surface of the positioning groove 11, the guide surface 14 is integrally vertical to the side wall of the positioning groove 11, the guide plates 13 are integrally constructed into a right-angle triangle shape, the nut on the support plate 20 moves towards the limit groove 12 under the pushing of the push plate 21, when the nut moves to the guide plates 13, the nut moves upwards along the guide surface 14, at the moment, the nut breaks away from the support plate 20, the push plate 21 keeps the pushing force of the nut, and when the nut moves to the highest point of the guide surface 14, the nut falls freely and falls onto the support plate 20 again, the push plate 21 continuously pushes the nut until the nut abuts against the limit groove 12, at the moment, the nut is supported by the support plate 20, and at the same time, the nut is clamped by the push plate 21, and tapping is completed under the clamped state; after the nut is tapped, the support plate 20 and the push plate 21 are retracted and reset, and the nut is free to fall after losing the support of the support plate 20 due to the blocking of the guide plate 13, so as to finish the withdrawing action.

In addition, the feed bin 15 has the inner peripheral face with nut appearance adaptation, the nut stacks up in the feed bin 15 inside, and accomplish the unloading under self gravity effect, the bottom of feed bin 15 and the top surface parallel and level of push pedal 21, the one nut of feed bin 15 below is located inside constant head tank 11, when push pedal 21 passes from feed bin 15 below, can push away this nut, simultaneously, push pedal 21 removes to the below of feed bin 15, can block the nut in the feed bin 15 and fall into constant head tank 11, until push pedal 21 before returning, push pedal 21 plays the effect of blockking up the nut in the feed bin 15 all the time, after push pedal 21 returns, push pedal 21 releases the jam to the nut in the feed bin 15, the nut in the feed bin 15 falls into constant head tank 11 again, so reciprocating.

It should be noted that, the supporting plate 20 is integrally and slidably attached to the bottom surface of the base 10, and the extension direction of the air cylinder 22 is parallel to the extension direction of the positioning slot 11, and the extension and retraction of the air cylinder 22 can drive the push plate 21 to periodically push the nut to move toward the limiting slot 12.
