Description

Angle mill guard shield clamping device

Technical field

The utility model relates to a kind of guard shield that is used for the angle mill, is in particular the guard shield clamping device of angle mill, belongs to field of power tools.

Background technology

When using the angle mill in to workpiece process, cause that through regular meeting chip splashes, this just need be provided with the protection guard shield between the working head of operating personnel and electric tool, come to harm to avoid operating personnel.Because guard shield body and angle mill body are dismountable, so a kind of angle mill guard shield clamping device need be provided now.Patent US5005321 has disclosed a kind of angle mill guard shield clamping device, its structure is the groove fit of the loam cake of projection on the guard shield body and angle mill body, size according to projection, quantity, shape is distinguished the relation between each guard shield body and the loam cake, make the guard shield body of each model all can only cooperate with the loam cake of this model, its defective is: because guard shield body and loam cake between each model are not general, so when the angle mill is installed the guard shield of different model, need the multiple loam cake that matches with it, versatility is relatively poor, and the work that causes changing angle mill guard shield becomes complicated unusually; Secondly, axle journal need process shoulder, groove and various opening, has increased infrastructure cost.Because the guard shield of angle mill grinds between the body and can rotate relatively with the angle, but the guard shield body can not envelope the grinding wheel of angle mill fully, so therefore operating personnel might need provide the limit function of the extreme angles of a kind of angle mill guard shield directly in the face of grinding wheel in the use of angle mill.

The utility model content

For overcoming the deficiency of existing angle mill guard shield clamping device technology, the purpose of this utility model is to provide a kind of novel angle mill guard shield clamping device, make the loam cake of angle mill its angle mill body when changing grinding wheel and guard shield have versatility, and do not need loam cake is changed in the lump.

Another purpose of the present utility model is to make the guard shield and the superstructure of angle mill simple, installs simple and easy.

Also purpose of the present utility model provides a kind of extreme angles limit function.

The technical scheme that the prior art problem that solves the utility model is adopted is:

A kind of angle mill guard shield clamping device, include: the guard shield body, the loam cake of fixedlying connected with angle mill body, fixed band and securing member, the guard shield body is socketed on and covers, fixed band is socketed on the fixed part of guard shield body, has one to connect mechanism between guard shield body and the loam cake, and the guard shield body of different model can be installed to and covers on same by connecting mechanism.

Further, the above-mentioned mechanism that connects includes groove and retaining element, and retaining element can slide in groove.

Again further, an opening and a stopper section are arranged on the above-mentioned groove, retaining element can enter the groove from opening part.

Again further, in the mill of the angle of different model, the above-mentioned opening and the size of retaining element, shape, quantity etc. are consistent.

Further, above-mentioned groove is arranged on the fixed part of guard shield body, and retaining element is arranged on the axle journal of loam cake, and above-mentioned fixed part is socketed on the periphery of axle journal.

Further, above-mentioned securing member is a screw, is arranged in the through hole of fixed band.

Further, above-mentioned retaining element is a projection.

Further, above-mentioned guard shield body and fixed band are fastenedly connected and are integral.

Compared with prior art, the beneficial effects of the utility model are: be provided with one and connect mechanism between guard shield body and loam cake, make the loam cake of angle mill its angle mill body when changing grinding wheel and guard shield have versatility, and do not need to change in the lump.And the utility model also provides the extreme angles limit function, necessarily has the protection guard shield between the working head of operating personnel and angle mill in the use that guarantees to grind at the angle.

The specific embodiment

As shown in Fig. 1 to Fig. 4, use angle of the present utility model mill to include angle mill body 2, loam cake 4 (showing among Fig. 5), guard shield body 6, fixed band 8, screw 10 and grinding wheel 12.As shown in Figure 2, the axle journal 16 of loam cake 4 is provided with projection 14.Projection is the preferable selection of retaining element, perhaps also can be with replacements such as screws.As shown in Figure 3, fixed band 8 is closed circle not, and its opening part has through hole 26.As shown in Figure 4, guard shield body 6 includes one along the axially extended fixed part 24 of its axis, and circumferential groove 18 is arranged on the fixed part 24.An end has opening 20 on the groove 18, and the other end has stopper section 22.Projection 14 and groove 18 compositions connect mechanism.In the angle mill of different model, in the angle mill guard shield clamping device that for example 100 millimeters, 115 millimeters, 125 millimeters grinding wheel needs, the opening 20 of groove 18 and size, shape, the quantity of projection 14 are consistent.Like this, the loam cake of the angle of these several models mill its angle mill body when changing grinding wheel and guard shield has versatility, and does not need to change in the lump.

As shown in Fig. 5 and Fig. 6, the projection 14 of loam cake 4 enters into groove 18 from the opening 20 of guard shield body 6.Like this, the fixed part 24 of guard shield body just is socketed on the periphery of the axle journal 16 of loam cake 4, and guarantees that guard shield body 6 can axially not coming off from loam cake 4.As shown in Fig. 1 and Fig. 5, screw 10 passes the through hole 26 of fixed band 8, and fixed band 8 is socketed in the periphery of the fixed part 24 of guard shield body 6 in the mode of welding.Like this, lock-screw 10 makes fixed band 8 strains, and the fixed part 24 of guard shield body 6 is fastenedly connected with loam cake 4.Because loam cake 4 is to be fixedly connected on the mill body 2 of angle by screw in the prior art, so guard shield body 6 promptly is fastenedly connected with angle mill body 2.

As shown in fig. 1, grinding wheel 12 is a full circle shape, and guard shield body 6 is semicircle, so the grinding wheel 12 of half area will inevitably be exposed at guard shield body 6 outsides at work.As shown in Figure 4, barrier effect just can be played to the projection 14 of loam cake 4 in the stopper section 22 of the groove 18 of guard shield body 6 of the present utility model, make guard shield body 6 position that after turning to an angle, reaches capacity, make with regard to having prevented guard shield body 6 from the position being installed like this operating personnel be directly exposed to the angle mill grinding wheel 12 in face of.

Except that above-mentioned preferred embodiment, the utility model still has multiple concrete embodiment.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
