Abstract

A kind of reciprocal isolated steel ball dispensing tool, is made up of lid, feed bin, handle, raceway, pressure cap, push rod, control valve, separated material piece, conduit, spring etc..Feed bin and handle are twisted match somebody with somebody together with, handle is embedded in a plastic tube, and the conduit of handle and lower end is fixed, and separated material mechanism is arranged between conduit and handle, is made up of push rod, control valve, back-moving spring etc..After thrust is applied to pressure cap, separated material piece is inserted between two steel balls, stops second steel ball, while the hole alignment conduit of control valve bottom, first steel ball are smoothly fallen from conduit.Pressure cap, spring reset are unclamped, separated material piece exits, and second steel ball falls on the position of first steel ball in control valve, and the stop of controlled valve bottom, realizes that a cycle circulates.This instrument can effectively control the outflow number of steel ball, the steel ball number needed by compression number, avoid steel ball from tumbling and form metal fifth wheel, eliminate hidden danger of quality, improve the efficiency of assembling of steel ball.

Description

A kind of reciprocal isolated steel ball dispensing tool

Technical field

It the utility model is related to a kind of isolated steel ball dispensing tool of linear reciprocation.

Background technology

J599 series electric connectors are widely used in the instrument and equipment of all kinds of aerospace models, and steel ball is series connection Vital part in device retaining mechanism.Need to install 6 steel balls in each plug, each steel ball needs to be accurately placed to one small The top of spring.In practical set, because little spring top is substantially equal with connection ring step surface, using the general work such as tweezers Steel ball often deviates its correct position during tool assembling, and the steel ball that steel ball hole is introduced into after anti-DNA releaxed circular DNA is loaded onto just withstands anti-DNA releaxed circular DNA It is not installed in place, anti-DNA releaxed circular DNA adjustment steel ball position need to be removed again, it is so repeated multiple times, brought to Product Assembly larger Difficulty.Steel ball often tumbles in assembling process simultaneously, easily forms fifth wheel, hidden danger of quality is brought to space product.

The content of the invention

The purpose of this utility model is to provide a kind of instrument that can isolate control steel ball, and the instrument can be by operator The outflow quantity of autonomous control steel ball, and it is accurately put into the position of requirement, have manipulation flexibly, it is easy to be reliable the characteristics of, Can solve the problems, such as that Product Assembly efficiency is low, avoid steel ball from arbitrarily tumbling.

Technical scheme is used by the utility model：A kind of reciprocal isolated steel ball dispensing tool, the instrument mainly wrap The parts such as feed bin, handle, raceway, pressure cap, push rod, control valve, separated material piece, conduit are included, by hand held structures, roller path structure and isolation Control structure three parts form.Hand held structures are together by a threaded connection with roller path structure, isolation control structure and hand-held knot Structure is fixed using screw, spring washer.

The cylindrical structural that the handle of the reciprocal isolated steel ball dispensing tool is diameter about φ 24mm, outer surface compacting Anti-skidding reticulate pattern, upper end are connected with feed bin, and lower end is connected with pig tail catheter, and isolation control is provided between handle and pig tail catheter Device.

The feed bin is circular funnel-shaped structure, and positioned at the top of instrument, bin outlet alignment raceway, raceway outlet enters Isolation controller, lower termination pig tail catheter, instrument keeps vertical or tilts certain angle during use, and steel ball is automatic by Action of Gravity Field Sort in raceway.

The isolation control device is a box structure, and its upper end sets a spacer to control second steel ball outflow, Lower end sets a dislocation hole.When pressure cap stress promotes isolation controller movement during use, spacer inserts bottom two in raceway Between individual steel ball, prevention second and above steel ball tumble, while the dislocation hole of isolation controller lower end and pig tail catheter hole pair Just, the steel ball in isolation controller flows out out of conduit；When removing thrust, spring promotes isolation controller to reset, and spacer moves back Go out raceway, isolation controller bottom hole misplaces with pig tail catheter hole, stops steel ball outflow.

Brief description of the drawings

Fig. 1 is reciprocal isolated steel ball dispensing tool structural representation

Embodiment

In Fig. 1, feed bin (2) is that upper and lower ends are helicitic texture, and upper end is twisted with connection, lower end with lid (1) by screw thread It is screwed into handle (3), the core pipe (4) of its hole alignment handle (3) center installation, its aperture and core pipe (4) internal diameter are identical or bigger. Core pipe (4) is by being interference fitted in embedded handle (3) centre bore, in the insertion isolation controller hole of core pipe (4) lower end, in core pipe (4) lower end is unilateral sets a groove, and the spacer (8) on isolation controller can be in groove slidably.In handle (3) lower end is provided with a square three-way groove, with lower end installation pig tail catheter (9) fixed by screw after form one it is square Hole, isolation controller can be in this square holes slidably.Spring (11) is provided with isolation controller one end, and on the outside of square hole Sprue 1 (2) is mounted with, prevents isolation controller to be pushed out.A spacer (2) is mounted with the isolation controller other end, every From a Step Shaft (2) is provided with the outside of piece (2), Step Shaft (2) taper end passes through sprue 2 (2), is threadably secured with pressure cap (2). When pressure cap (2) stress promote isolation controller when spacer (2) insertion core pipe (2) stop second steel ball fall, and in every Flowed out after then being alignd from first steel ball inside controller by the circular hole of its lower end with conduit (2) centre bore, effectively control The outflow quantity of steel ball and position, avoid producing unnecessary steel ball.

Claims (2)

1. a kind of reciprocal isolated steel ball dispensing tool, the instrument mainly include feed bin, handle, raceway, pressure cap, push rod, control The parts such as valve, separated material piece, conduit, it is made up of hand held structures, roller path structure and isolation control structure three parts；The hand held structures For diameter about φ 24mm cylindrical handle, anti-skidding reticulate pattern is suppressed in outer surface, and the feed bin of upper end and roller path structure is connected by screw thread Connect, the conduit of lower end and roller path structure is connected by screw；The isolation controller is embedded in what is set between handle and catheter In square groove.

2. reciprocal isolated steel ball dispensing tool according to claim 1, it is characterised in that：It is described isolation control device be One box structure, its upper end set spacer to control second steel ball outflow, and lower end sets a dislocation hole, work as during use Pressure cap stress promotes isolation controller movement, in spacer insertion raceway between the steel ball of bottom two, prevent second and more than Steel ball tumbles, while the dislocation hole of isolation controller lower end aligns with pig tail catheter hole, and the steel ball in isolation controller is from conduit Interior outflow；When removing thrust, spring promotes isolation controller to reset, and spacer exits raceway, isolation controller bottom hole and cone Shape guide hole misplaces, and stops steel ball outflow.
