Abstract
The utility model discloses a bench drill protective device which comprises a movable protective cover made into a cylindrical shape by two half cylinder walls, wherein one end of the inner side of the movable protective cover is provided with a wide flute and the other end is provided with a narrow flute; a drill protective cover is arranged in the narrow flute which is arranged on the inner side of the movable protective cover through the flange, and one end of the flange bulges outward; a fixed protective cover is arranged in the wide flute which is arranged on the inner side of the movable protective cover through the flange, and one end of the flange bulges outward. Compared with the prior art, the protective device makes the iron dust not scatter everywhere when used in operating the bench drill, and an operator can work with gloves; the utility model can really have the function of safeguard protection and can automatically discharge dust, which can improve the work efficiency of the workers. The utility model is suitable for drilling thin-wall pipes in machine work for factories and enterprises.
Description
Technical field
The utility model relates to a kind of bench drill safety guard technical field, especially a kind of bench drill safety guard that is used to bore light-wall pipe.
Background technology
As everyone knows, during the operation bench drill, the safety code regulation can not be dressed gloves, in case drilling machine high speed rotating handles cover hinge is lived, therefore the workman can only catch part with an exposed hand, the feed arrangement work of another hand operated drilling machine, the burr that the high-temperature iron scurf that the exposed usually drilled headband of hand rises is scalded and part is sharp-pointed scratches.At present, also have the bench drill of some manufacturer production that safety guard is arranged, but they only are that a straight sleeve is simply surrounding around the drill bit; and can not slide up and down; the operator still can not wear gloves work, does not all have in the actual production to use at all, does not still play the effect of safeguard protection.Though also there are some achievements in research to realize similar function; (patent No. is: the device that ZL91213791.6) discloses a kind of dustproof bits such as Chinese patent " light motor-driven impacting, boring bar tool duster "; it only is applicable to the device that the workman uses electric hand drill, percussion drill and electric hammer to carry out such as the decoration effect and a kind of dustproof bits when upwards punching fly upward, and is not suitable for and does not also relate to factory and enterprise and carry out the employed bench drill safety guard of machined.
Summary of the invention
The purpose of this utility model is to provide a kind of bench drill safety guard, and it mainly solves, and the workman can not control the iron filings flow direction in the prior art scheme when using bench drill, can not wear the problem of gloves operation.
The purpose of this utility model is achieved in that it includes one and surrounds the movable protective sleeve of tubular by two lobe barrels, inboard one end of this activity protective sleeve is provided with wide groove, the inboard other end is provided with narrow groove, has a drill bit protective sleeve to be contained in the narrow groove of described movable protective sleeve inboard by the flange that the one end outwards protrudes; Have one fixedly protective sleeve be contained in the wide groove of described movable protective sleeve inboard by the flange that the one end outwards protrudes.
Above-mentioned drill bit protective sleeve side can be provided with through hole; The inboard, outer end of said fixing protective sleeve can be provided with connecting thread; Side engagement place between the barrel of above-mentioned movable protective sleeve can flexibly connect by hinge, and their opposite side can be connected with bolt in being contained in lockhole by the lockhole that is provided with on it.
Because adopted and stated such scheme, the utility model compared with prior art has following beneficial effect:
1, use this protective device when the operation rig floor, iron filings can not splash everywhere, and the operator can wear gloves work, really plays the effect of safeguard protection.Because movable protective sleeve surrounds the drill point of bench drill and rotary main shaft; the drill bit protective sleeve surrounds drill bit; the rotating part of bench drill is closed fully at work; thereby iron filings can not be splashed everywhere; the rotating part of bench drill and operator are isolated; the operator can wear the gloves worker, really plays the effect of safeguard protection.
2, can fall to consider to be worth doing automatically, improve work efficiency of workers.Because the fixedly protective sleeve that is connected with the feeding main shaft by screw thread is to be contained in the groove of movable protective sleeve; therefore the feeding main shaft can drive drill bit by drill point and moves up and down in movable protective sleeve; after having bored the hole; the feeding main shaft drives drill bit and movable protective sleeve moves upward; the drill bit protective sleeve leaves workpiece; drill bit leaves the drill bit protective sleeve, and the iron filings in this guard member are fallen down by the through hole of its lower end automatically, reaches the purpose of falling to consider to be worth doing automatically.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawing example:
As Fig. 1; among the embodiment shown in Figure 2; it includes the movable protective sleeve 3 that is surrounded tubular by two lobe barrels the utility model; inboard one end of this activity protective sleeve is provided with wide groove 4; the inboard other end is provided with narrow groove 6; drill bit protective sleeve 5 is contained in the narrow groove 6 of movable protective sleeve 3 inboards by the flange 7 that the one end outwards protrudes; fixedly protective sleeve 1 is contained in the wide groove 4 of movable protective sleeve 3 inboards by the flange 8 that the one end outwards protrudes; drill bit protective sleeve 5 sides are provided with through hole 9; fixedly the inboard, outer end of protective sleeve 1 is provided with connecting thread 10; side engagement place between the barrel of movable protective sleeve 3 flexibly connects by hinge, and their opposite side is connected with bolt 2 in being contained in lockhole by the lockhole of setting it on.
Specific operation process:
Fixing protective sleeve 1 is enclosed within on the feeding main shaft of bench drill; threaded together; fix; one side of two lobe barrels of movable protective sleeve 3 is connected with hinge; the opposite side opening; the flange 7 of drill bit protective sleeve 5 is contained in the narrow groove 6 of movable protective sleeve 3; again movable protective sleeve 3 is contained in fixedly on the protective sleeve 1; making fixedly, the flange 8 of protective sleeve 1 is contained in the wide groove 4; synthetic tubular activity protective sleeve; with bolt 2 lockhole that is provided with on movable protective sleeve 3 opposite sides is locked, the whole rotation position of bench drill all is surrounded so again.During work feed; whole device moves downward with bench drill feeding main shaft; after drill bit protective sleeve 5 is run into workpiece; drill bit protective sleeve 5 and movable protective sleeve 3 no longer down move; and fixedly protective sleeve 1 is to be threaded with the feeding main shaft; with movable protective sleeve 3 is that movable track is connected, thereby fixedly protective sleeve 1 continuation finishes until boring along with the feeding main shaft down moves.In this process, because of drill bit protective sleeve 5 is arranged drill bit is surrounded, iron filings can not splash everywhere, have entered space that drill bit protective sleeve and movable protective sleeve form but consider groove to be worth doing along drill bit.Move back when boring; fixedly protective sleeve 1 up moves with the bench drill main shaft; when fixedly protective sleeve flange 8 is anchored to the edge of wide groove 4; drill bit protective sleeve 5 and movable protective sleeve 3 also up motion thereupon; workpiece is left in drill bit protective sleeve lower end; the through hole 9 of its side is not subjected to the interference of drill bit drilling rod yet, and iron filings are fallen down by through hole 9 automatically, reaches the purpose of automatic crumb unloading.
