Description

Screw catching attachment of screwdriver with consecutive feed

The utility model relates to power-driven tool, and particularly the device of catching screw is caught in a kind of continuous conveying used of screwdriver.

At present, carry screw, catch and catch screw, generally rely on people's hand or manipulator, adopt people's hand,, and be subjected to the restriction of steric requirements though dexterity is time-consuming to screwdriver; If adopt manipulator, though laborsaving manufacturings is complicated, optional equipment is many, and fixed point use, not portable, the device of a kind of automatic trip bolt of introducing as Japan Patent JP58-51082 is exactly like this, this is for field or the big operation inconvenience of flowability.

The purpose of this utility model is exactly at above-mentioned deficiency, provides a kind of and can replace staff, make simple, light and handy flexibly, portablely again can catch the device of catching screw with the continuous conveying that multiple screw cutter connects use.

Technical solution of the present utility model is, use a three-way pipe＜8 〉, a port that passes through at screwdriver is loaded onto and is caught nail device＜9 〉, there are the connector＜5 〉, the banking pin＜7〉that connect with screwdriver that connector＜5〉reliably is connected with three-way pipe＜8〉in its another port, and power interaction energy relative motion outside.Be equipped with at the arm eck of three-way pipe＜8〉and only send switch＜14 〉, the feed pipe＜10〉that control valve＜12〉are housed inserts from the mouth of pipe that the three-way pipe＜8〉that only send switch＜14〉is housed, have on the feed pipe＜10〉and can make control valve＜12〉block the bayonet slot＜30〉of screw, the fixedly card＜1〉that connects with screwdriver is equipped with in feed pipe＜10〉upper end, screw＜2〉is fastening with it, so that can drive feed pipe＜10〉during the screwdriver motion moves along the three-way pipe arm that is inserted in, catching in the nail device＜9〉magnet ring＜18〉that can adsorb screw to be housed and can to block screw does not make its pearl that bumps that skids off encircle＜20 〉, overcoat tight loop＜19 〉; Only send switch＜14〉by collar＜13 〉, alignment pin＜15 〉, only send valve compositions such as＜16 〉.When only sending the switch position that＜14〉are in out, control valve＜12〉moves downward and can move, and makes screw fall into three-way pipe＜8 〉; When the position of only sending switch＜14〉to be in the pass, be not triggered during control valve＜12〉moves downward, its as a result screw can not fall into three-way pipe＜8 〉; Control valve＜12〉comprises control valve＜27 〉, down control valve＜24 〉, tension spring＜11 〉, vavle shelf＜23〉etc., on control valve＜27〉and following control valve＜24〉interoperation, one closes one opens, and moves each time, all makes one piece of screw send into three-way pipe＜8 〉.Operation principle of the present utility model is as follows: when the utility model and screwdriver (manual screw cutter, semi-automatic screwdriver or pneumatic screw driver, electric screw driver all can) when connecting, fixing card＜1〉is fixedly blocking screw driver handle or close handle place in the feed pipe＜10 〉, and screwdriver rod is inserted in connector＜5〉and three-way pipe＜8 〉.At this moment, the screw that feed pipe＜10〉dress foot will be carried, with screwdriver to pressing down, drive the arm motion of feed pipe＜10〉to lower edge three-way pipe＜8 〉, when the notch on the screwdriver contact screw head, only send the inclined-plane of switch＜14〉that control valve＜27〉cuts out, stop screw to fall; When the screwdriver rotary screw puts in place, only send the inclined-plane of switch＜14〉that control valve＜24〉is opened, formerly controlled one piece of screw that valve blocks down and just fallen into three-way pipe＜8 〉; When screwdriver lifts, owing to spring＜6 〉, three-way pipe＜8〉is subjected to outwards motion of connector＜5〉effect, and this piece screw just slips into and catches nail device＜8 〉.Control valve＜12〉with only send switch＜14〉to disengage after, because the effect of tension spring＜11〉forces down control valve＜24 〉, on control valve＜27〉and reset rapidly successively that (following control valve＜24〉is the pass earlier, open behind the last control valve＜27 〉), the screw in the feed pipe＜10〉moves down one successively.This process is gone round and begun again.As unload screw, as long as will only send switch＜14〉puts to the position of " pass ", only send this moment valve＜16〉groove mouth to aim at the route of control valve＜24〉motion down, when screwdriver drives feed pipe＜10〉when moving downward, although screwdriver is unloading screw, following control valve＜24〉can breakdown, when being discharged into, screw catches nail device＜9 〉, lift screwdriver, repeat the screwdriver pressing action, promptly from catch nail device＜9 〉, take out screw.In order to make screwdriver rod can advance trip bolt in the workpiece deep hole deeply, can regulate fixing card＜1〉and connector＜5〉at the relative position that connects on the screwdriver of use, screwdriver rod can be exposed catch that nail device＜9〉is outer has a degree of depth that can put on the workpiece in the deep hole and can mounting screw, screwdriver just can be fastened on screw in the deep hole of workpiece like this.For making feed pipe＜10〉output screw continuously of carrying screw, can change one section after having gone up again at one section screw special pipe of feed pipe＜10〉upper end socket casket, need only and get the pipe casket that the different size screw is housed in advance ready, it is very convenient to work together.Also can use the additional feed pipe that has electromagnetic shaker in addition, be suspended on the station.The dispatch screw guarantees to produce automatically so incessantly; Can also solve the fixedly work of the many screws of porous, produce standard component in batches, the whole positioning tool of an additional cover can shorten working procedure, once finishes.

Advantage of the present utility model is that mobility is big, makes simple; Catch that to catch screw reliable, and can adsorb iron washer; Adapt to the work of different directions trip bolt, the control screw guarantees screw is stuck in the feed pipe when falling; The screwdriver of being convenient to plurality of specifications and type connects, and it is suitable for carrying, and is particularly suitable for open-air and mobile big operation or does not have under the situation of manipulator and repeat the work that fly is followed closely.
