Description
[technical field]
The utility model relates to a kind of equipment that screws, and relates in particular to magnetic-type batch of mouth of a kind of full-automatic screw fixing machine.
[background technology]
Electric screwdriver is also electric screw driver, electric screw driver, is the electric tool of using for tightening and unscrew screw.This electric tool is equipped with the mechanism of adjusting and torque limiting, is mainly used in assembly line, is one of instrument of most of manufacturing enterprise indispensability.
Shown in Fig. 3, for batch mouth common in prior art, electric screwdriver bar 1 inside has electric screwdriver bottle opener 2, batch mouth 3 is installed, on the top of electric screwdriver bar 1 shown in Fig. 3, criticize mouth 3 and there are upper and lower two mouth pawls 31, mouth pawl 31 is rotatably connected on screwdriver bit 3, and is provided with spring 32 between its one end and screwdriver bit 3, after work screw 4 is sent into by external impetus from entrance 5, arrive mouth pawl 31 places and blocked by two mouth pawls 31, when electric screwdriver 1 can back down mouth pawl 31 when pressing down, throw in screw again.This sample loading mode has following shortcoming:
1, can often block screw: because the hole of two mouth pawls is less than the hole that other located screw, boring ratio screw thread part between two mouth pawls is less than nut part greatly, could allow like this screw only at mouth pawl place, stop, the reason that screw blocks has a lot of possibilities, modal is that the profile of screw is nonstandard, screw does not enter the aperture between mouth pawl, will manually move mouth pawl and could take out screw after getting stuck.
2, the bad screw that moves back: the operation principle of this electric screwdriver is the screwdriver bit mouth contact screw hole limit of batch mouth, electric screwdriver is pressed onto screw hole top by screw and throws into toward pressing down, when electric screwdriver unclamps, having a screw can be sent to batch in the mouth at once, that is to say, electric screwdriver often presses down and once just has a screw and be admitted to screwdriver bit mouth, if screw does not enter in screw when screwing, on screw limit, withstand and will can not get through, at this moment ought unclamp electric screwdriver just has again a screw to be admitted to batch mouth, now criticize and just have in the mouth two screws, now screw will be taken out, and that at present this batch of mouth mode blocked sometimes is very dead, screw is inconvenient to take out.
3, screw can tilt: electric screwdriver bottle opener can tilt while pressing screw to walk downward disengaging mouth pawl.
4, cause wearing and tearing: electric screwdriver bottle opener rotates when work, when electric screwdriver bottle opener is pressing screw to walk downward, can rotate friction with mouth pawl.
5, manufacturing procedure is many: finished product will pass through the manufacturing procedures such as car, milling, mill, line cut, heat treatment.
6, processing technology is more difficult: workpiece is less, and the place that process is many, has the place of the bad processing in many places.
[utility model content]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, provides a kind of and can not block screw, without the material returned and reduced magnetic-type batch of mouth of full-automatic screw fixing machine of spin friction.
The technical solution of the utility model is achieved in that magnetic-type batch of mouth of a kind of full-automatic screw fixing machine, detachable being connected on electric screwdriver of this magnetic-type batch of mouth, described magnetic-type batch of mouth comprises a screwdriver bit, on screwdriver bit, there is work screw entrance, its improvements are: described screwdriver bit inside has the screw passage being communicated with work screw entrance, the end of screwdriver bit is connecting the screwdriver bit mouth that a middle part has through hole, and a magnet of the outer installation of described screwdriver bit mouth, the screw that work screw entrance drops can be lived by described magnet adsorption.
In above-mentioned structure, described batch of mouth consists of one-body molded screwdriver bit mouth portion and screwdriver bit mouth fixed part, and between screwdriver bit mouth portion and screwdriver bit mouth fixed part, be step-like, the internal diameter of above-mentioned magnet equates with the external diameter of screwdriver bit mouth fixed part, and described magnet be placed on screwdriver bit mouth fixed part.
In above-mentioned structure, on described screwdriver bit mouth fixed part, there is a steady pin position, on described electric screwdriver head, there is the screw hole running through with screw passage, in this screw hole, be provided with jackscrew, and described jackscrew top is pressed on the steady pin position of above-mentioned screwdriver bit mouth fixed part.
The beneficial effects of the utility model are: this kind of structure of the present utility model, there will not be screw to be stuck in situation about criticizing in the mouth, very smooth and easy of process of lock screw, electric screwdriver bottle opener is magnetic conductor, screw also can be inhaled on electric screwdriver bottle opener after being extruded by electric screwdriver bottle opener, employing is without the structure of mouth pawl, during the rotation of electric screwdriver bottle opener, can not rub with mouth pawl, in addition, the overall structure of electric screwdriver changes in little situation and has reduced manufacturing procedure and difficulty of processing, changes screwdriver bit mouth and can share with the electric screwdriver of other kinds.
