Abstract
The invention discloses a copper head receiving and placing mechanism for a cartridge assembly machine. The copper head receiving and placing mechanism comprises a clasping sleeve, a holding sleeve and a blanking depth positioning rod. By taking a using direction as reference, the outside wall at one end of the holding sleeve is a truncated conical surface; a through hole is formed inside the holding sleeve; at least one axial open groove communicated with the internal and the external of the holding sleeve is formed on the side wall at one end of the holding sleeve; a truncated conical hole matched with the outside wall of the holding sleeve is formed inside the clasping sleeve; the clasping sleeve is axially arranged outside one end of the holding sleeve movably; and the blanking depth positioning rod is fixedly inserted inside the other end of the holding sleeve. By mutual matching of the clasping sleeve and the conical surface of the holding sleeve, the holding sleeve shrinks to clamp a copper head; the clamping force of the copper head is ensured; the blanking depth positioning rod is used for positioning the length of the copper extended into the holding sleeve and simultaneously effectively protects a roll ball on the copper head; and the structure can accurately position and fix the copper head, simultaneously facilitates the assembly of a cartridge, also effectively protects the roll ball of the copper head from being damaged, and ensures smooth writing of the cartridge.
Description
Technical field
The present invention relates to a kind of pen core assembly machine, particularly a kind of pen core assembly machine copperhead connects discharge mechanism.
Background technology
Conventional copperhead is the sub warhead form, pen core assembly machine copperhead matching used with it connects discharge mechanism and adopts an armful tube upper end to establish bellmouth, the taper surface of copperhead lower end and this bellmouth coupling, by the bellmouth location of embracing tube and provide thrust to assemble, conventional bullet-shaped copperhead weight is bigger, blanking is smooth, and for the needle-like copperhead, itself weight is less, under the frictional force influence in discharging tunnel, blanking is not smooth, the frictional force of position entrance of connecting material can cause, and copperhead enters the position that connects material and also has some setbacks, because of its size tiny, dock the precision that keeps higher with the entrance that connects material so require the discharging tunnel face, connect material in the actual use and be out of order easily, and because its diameter is too thin, the bellmouth of embracing tube can't provide sufficient thrust that it is joined through luggage to it, the ball that also weares and teares easily causes ball to damage influence and writes.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of pen core assembly machine copperhead and connect discharge mechanism, it is simple in structure, accurate positioning, clamping is reliable.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of pen core assembly machine copperhead connects discharge mechanism; comprise and hold sleeve tightly; embrace tube and blanking depth localization bar; to use direction to be benchmark; embrace tube one end lateral wall and be the truncation conicoid; embrace the tube inboard and be provided with through hole (embrace the inboard through-hole diameter of tube and be slightly larger than the copperhead external diameter); embrace tube one distolateral wall and be provided with at least one connection armful inside and outside shaft orientation opening groove of tube; holding the sleeve inboard tightly is provided with and the truncation tapered hole of embracing tube lateral wall coupling; hold axially movable being sheathed on of sleeve tightly and embrace the tube one end outside; blanking depth localization bar fixedly is inserted in embraces tube other end inboard; original state is separated with an armful tube for holding sleeve tightly; embrace tube and be relaxation state; copperhead is in the assembly machine effect falls into the through hole of embracing tube; the ball of copperhead lower end only peaks at blanking depth localization bar upper end end face; copperhead deviates from ball one side preseting length and is exposed to armful tube one an end outside; then hold the sleeve axially-movable tightly and be placed in an armful tube outside; embracing the tube lateral wall is subjected to holding the ending the top of sleeve madial wall tightly and inwardly tightens up; like this copperhead just embraced that a tube madial wall clamps can not freely-movable; pen core tube can be installed outside the copperhead this moment; copperhead just has been installed in pen core tube one end like this; this structure can accurately be located and fixing copperhead; make things convenient for the assembling of pen core effectively to protect the ball of copperhead not to be damaged simultaneously; guarantee that pen core writes smooth and easy; be common structure as for holding quill tightly to removable frame; as pass through cylinder; oil cylinder drives; or can both drive its axially-movable by connecting rod or cam etc.; this is the structure that those of ordinary skill is all known, and introduces its concrete structure herein no longer in detail.
As a further improvement on the present invention, the quantity of embracing shaft orientation opening groove on the tube one distolateral wall is four, forms the petal type structure, makes armful tube one a distolateral wall have better elastic.
As a further improvement on the present invention, side through hole one end is provided with chamfering structure in the described armful of tube, makes things convenient for copperhead to fall in the through hole of embracing tube.
As a further improvement on the present invention, side through hole is that an end diameter is less than the notch cuttype through hole of other end diameter in the described armful of tube, blanking depth localization bar one end diameter is greater than this notch cuttype through hole one end internal diameter, guarantee that the copperhead other end falls within on blanking depth localization bar one end face all the time, prevents that the ball of copperhead from damaging.
As a further improvement on the present invention, the described acute angle angle of the inboard truncation tapered hole of sleeve and radial end face formation of holding tightly is smaller or equal to embracing the acute angle angle that tube lateral wall truncation conicoid and radial end face form, the truncation conicoid of holding the sleeve inboard like this tightly can fit tightly with armful truncation conicoid in the tube outside, and assurance is held the smooth and easy assurance simultaneously of sleeve slip tightly and embraced the stable chucking power of tube madial wall generation.
As a further improvement on the present invention, described armful of tube one end lateral wall is the truncated cones face, holds the sleeve inboard tightly and is provided with and the truncated cones hole of embracing tube lateral wall coupling.
Useful technique effect of the present invention is: the present invention establishes shaft orientation opening groove at an armful tube sidewall makes an armful tube sidewall produce an elasticity; cooperatively interact to make by a taper seat of holding sleeve and armful tube tightly again and embrace tube contraction clamping copperhead; guarantee the chucking power of copperhead; blanking depth localization bar is used for locating copperhead and stretches into the effective ball of protecting on the copperhead of length while that wraps in the tube; this structure can accurately be located and fixedly copperhead is simultaneously; make things convenient for the assembling of pen core; also effectively protect the ball of copperhead not to be damaged, guarantee that pen core writes smooth and easy.
