Abstract
The invention relates to the field of nail embedding equipment, in particular to a quick detection mechanism for a nail-embedded nut, which comprises a measuring rod, wherein the measuring rod is made of an insulating material, a measuring end is arranged at the bottom end of the measuring rod, block-shaped grooves distributed in a circumferential array are arranged at the measuring end, an L-shaped metal electrode block is embedded in each block-shaped groove, the L-shaped metal electrode block is connected with a self-recovery fuse in series through a lead and then connected with a rectifier bridge in parallel, and a buzzer is connected with the rectifier bridge in series. According to the invention, the measuring rod with an insulating structure is adopted, the L-shaped metal electrode block is embedded on the measuring end at the bottom of the measuring rod, the measuring end is inserted into the metal nut after the nail is embedded in the vertical direction, if the metal nut is inclined, the L-shaped metal electrode block can be contacted with the linear end of the L-shaped metal electrode block at the measuring end, the L-shaped metal electrode block can be conducted to form a short circuit, and the buzzer can sound to give an alarm; in the same way, in the process of inserting the metal nut, whether the nail embedding depth meets the requirement is judged by whether the protruding part of the L-shaped metal electrode block contacts the metal nut.
Description
Technical Field
The invention relates to the field of nail burying equipment, in particular to a quick detection mechanism for a nail-buried nut.
Background
Along with the development of industry injection molding machine trade, injection moulding product kind is various day by day different, the requirement to the supporting mould of injection molding machine is improved relatively when new injection moulding product is more and more duplicated, injection moulding product is used very much now behind the copper nut buries in the mould, the fixed depth and the straightness that hangs down of copper nut in plastics need accord with standard rear and can use, and generally measure through artifical range estimation or with the slide caliper rule manual work among the prior art, artifical measurement not only the error is big and detection time is long, inefficiency, product production's time has more increased.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a quick detection mechanism for detecting whether a buried nut reaches a specified standard.
The technical scheme adopted by the invention is as follows:
the utility model provides a bury female quick detection mechanism of nail, includes the measuring stick, the measuring stick is insulating material the bottom of measuring stick is equipped with the measuring end is equipped with the cubic recess that is circumference array distribution, inlays be in what be in the cubic recess is L shape metal electrode piece, L shape metal electrode piece passes through the wire and is parallelly connected with the rectifier bridge after establishing ties with the self-resuming fuse, with what rectifier bridge series connection was bee calling organ.
Compared with the prior art, the invention has the following beneficial effects:
the invention relates to a quick detection mechanism for a screw nut with an embedded nail.A measuring rod with an insulation structure is adopted, an L-shaped metal electrode block is embedded at the measuring end at the bottom of the measuring rod, the measuring end is inserted into the metal nut with the embedded nail in the vertical direction, if the metal nut is inclined, the L-shaped metal electrode block can be contacted with the linear end of the L-shaped metal electrode block at the measuring end, the L-shaped metal electrode block can be conducted to form a short circuit, and a buzzer can sound to give an alarm; in the same way, in the process of inserting the metal nut, whether the nail embedding depth meets the requirement is judged by whether the protruding part of the L-shaped metal electrode block contacts the metal nut.

Detailed Description
Referring to the attached drawings 1-5, the quick detection mechanism for the embedded nail nuts comprises a measuring rod 1, wherein the measuring rod 1 is made of an insulating material, a measuring end 2 is arranged at the bottom end of the measuring rod 1, block-shaped grooves 3 distributed in a circumferential array are formed in the measuring end 2, an L-shaped metal electrode block 4 is embedded in the block-shaped grooves 3, the L-shaped metal electrode block 4 is connected with a self-recovery fuse 5 in series through a lead and then connected with a rectifier bridge 6 in parallel, and a buzzer 7 is connected with the rectifier bridge 6 in series. The invention relates to a quick detection mechanism for a nail-embedded nut.A measuring rod 1 with an insulating structure is adopted, and an L-shaped metal electrode block 4 is embedded on a measuring end 2 at the bottom of the measuring rod, when in test, the measuring end 2 is inserted into a metal nut after the nail is embedded in the vertical direction, if the metal nut is inclined, the metal nut can be contacted with a linear end 4-1 of the L-shaped metal electrode block 4 of the measuring end 2, the L-shaped metal electrode block 4 can form a short circuit and promote a self-recovery fuse 5 to be tripped off within 2-3 s, only a very small part of current flows through the self-recovery fuse 5, most of the current forms a loop through a buzzer 7 after passing through a rectifier bridge 6, and the buzzer 7 gives out a sound alarm; and in the same way, the invention judges whether the nail embedding depth meets the requirement by inserting the nail embedding depth into the metal nut, judging whether the convex part 4-2 of the L-shaped metal electrode block 4 contacts the metal nut or not and judging whether the nail embedding depth meets the requirement by the buzzer 7. The invention is used synchronously with the mechanical arm, if the detected nail burying points are more, a plurality of mechanisms of the invention can be arranged on the template, and the detection of the nail burying can be completed by the mechanical arm gripping the template.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention in any way, so that any person skilled in the art can make changes or modifications to the equivalent embodiments using the above disclosure. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are still within the protection scope of the present invention, unless they depart from the technical spirit of the present invention.
