Description

There is the electric mill of protector

Technical field

The utility model relates to electric tool technical field, especially relates to a kind of electric mill with protector.

Background technology

Electric mill be a kind of common for polishing, cutting metal material or carry out the on the metal material electric tool of holing.Concretely, electric mill comprises housing, is provided with motor equal power device in this housing, and the power output shaft of this motor extends the outside of this housing.During use, only need fix the different tool heads such as bistrique, cutter head, drill bit in the leading section of the power output shaft of this motor, can different operations be carried out.

But when using electric mill to carry out operation, tool heads must form some splashings and go out metallic particles after rotating, those particles not only aggravating working environment, the more important thing is, those particles also damage places such as human eyes most probably.

Summary of the invention

The purpose of this utility model is to provide a kind of electric mill with protector, and it has the impact that can reduce particle preferably and cause, and structure simple, be easy to the feature that operates.

The technical scheme that the utility model adopts is: the electric mill with protector, comprise housing, this housing comprises the upper casing and lower casing that link together, the front portion of this upper casing and lower casing is equipped with the convex edge extended forward, these 2 convex edges can be combined, and the outer surface of these 2 convex edges is equipped with external screw thread thus the outside of be combined 2 convex edges is bolted with nut, simultaneously, motor is provided with in this housing, in the middle of these 2 convex edges, the outside to this housing is passed after the power output shaft of this motor extends forward, and the front end of this power output shaft is connected with tool heads, the described electric mill with protector also comprises protector, this protector comprises the circle body that can be enclosed within the outside of 2 convex edges be combined, the side of this circle body is provided with connection watt, the outer ledge of this connection watt extends to form forward the back-up ring of a cabochon, simultaneously, the rear end face of this nut compresses the front end face of this circle body, and, the front end face avris of this back-up ring is provided with a pivot bolt, simultaneously, this protector also includes a baffle plate, the mating holes that this baffle plate is provided with and this pivot bolt matches.

Be provided with guide bolt in the middle part of the front end face of described back-up ring, this baffle plate be also provided with and the guide channel of arc that this guide bolt matches meanwhile, this guide channel with this mating holes for the center of circle.

Described baffle plate is fan-shaped.

Described connection watt is protracted in skewed.

The leading edge of described back-up ring extends internally to be formed and hooks edge.

The utility model is compared to the prior art advantageously: can reduce the impact that particle causes preferably, and structure is simple, is easy to operation.The electric mill with protector of the present utility model, by arranging the back-up ring of cabochon in the proper orientation of the tool heads such as bistrique, greatly reduces the impact of particle on working environment, more reduces the probability of particle to the injury that operator's human body causes.Meanwhile, because back-up ring to be fixed on the leading section of housing by circle body, and very easily adjust the position of back-up ring by rotating, thus structure is comparatively simple, it is very convenient to operate.

Detailed description of the invention

Embodiment, is shown in shown in Fig. 1 and Fig. 2: the electric mill with protector, comprises housing.This housing comprises the upper casing 11 and lower casing 12 that link together, and the front portion of this upper casing 11 and lower casing 12 is equipped with the convex edge 13 extended forward.These 2 convex edges 13 can be combined, and the outer surface of these 2 convex edges 13 are equipped with external screw thread thus the outside of be combined 2 convex edges 13 is bolted with nut 20.That is, the middle part of this upper casing 11 and lower casing 12, rear portion can be fixed together by the mode of engaging, and the anterior restriction by nut 20, makes this upper casing 11 and lower casing 12 form the housing that has closure inner chamber.Meanwhile, motor (not shown on figure) is provided with in this housing.In the middle of these 2 convex edges 13, the outside to this housing is passed after the power output shaft 30 of this motor extends forward.Obviously, the center of 2 convex edges 13 be combined is provided with the cooperation passage passed for this power output shaft 30 matched in clearance.The front end of this power output shaft 30 is connected with the tool heads 40 such as bistrique, cutter head, drill bit.Certainly, this motor must be furnished with the parts such as switch, control circuit.

Further say, shown in composition graphs 3 to Fig. 5, this electric mill with protector also comprises protector.This protector comprises the circle body 51 that can be enclosed within the outside of 2 convex edges 13 be combined.The side of this circle body 51 is provided with and connects watts 52, and the outer ledge of this connection watts 52 extends to form forward the back-up ring 53 of a cabochon.Meanwhile, the rear end face of this nut 20 compresses the front end face of this circle body 51.That is, under the prerequisite of original structure not changing this electric mill, only need to take off this nut 20, this circle body 51 can be enclosed within the outside of these 2 convex edges 13, or, this circle body 51 is taken off from the outside of these 2 convex edges 13; Otherwise, after this circle body 51 is enclosed within the outside of these 2 convex edges 13, screw this nut 20, this circle body 51 can be limited in the outside of these 2 convex edges 13.And, only need to adjust this back-up ring 53 to correct position, can the particle that tool heads 40 is formed be stopped.

The front end face avris of this back-up ring 53 is provided with in the middle part of a pivot bolt 61, front end face and is provided with guide bolt 62.Certainly, this guide bolt 62 also can be screw or projection.Meanwhile, this protector also includes a baffle plate 70, and this baffle plate 70 is preferably in fan-shaped.The mating holes 71 that this baffle plate 70 is provided with and this pivot bolt 61 matches and and the guide channel 72 of arc that matches of this guide bolt 62, this guide channel 72 with this mating holes 71 for the center of circle.That is, this pivot bolt 61 to be through in this mating holes 71 thus this baffle plate 70 can with this pivot bolt 61 for rotating shaft rotates; This guide bolt 62 is through in this guide channel 72 to play the effect that this baffle plate 70 of guiding rotates.Like this, further block the particle flown out forward, make protection more comprehensive.And, as shown in Figure 6 and Figure 7, by rotating this baffle plate 70 to different angles, different protection effects can be obtained.

Optimize:

The cross section of this connection watts 52 such as can be rectangular in shape at the common shape.In the present embodiment, this connection watts 52 is protracted in skewed.Like this, make the connection of this back-up ring 53 and this circle body 51 comparatively smooth, be also conducive to the trend guiding particle.

The leading edge of this back-up ring 53 extends internally to be formed and hooks along 531.Like this, the intensity of this back-up ring 53 can not only be increased, and be conducive to the gathering of particle.Now, this pivot bolt 61 and this guide bolt 62 can be installed on this hook along on 531.

The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
