The specific embodiment

See also Fig. 1, be arranged at the three-dimensional exploded view of drilling machine for the utility model.The laser auxiliary locator 1 of this drilling machine and electric drill, be arranged on the casing 94 of drill bit 92 tops of drilling machine 90, include a bogey 10, a pair of laser generator 20 be located on this bogey 10, and at least one on-off controller 40 to control this laser generator 20.

The profile of this bogey 10 slightly becomes L shaped in this enforcement, is provided with two microscler storage tanks 12 thereon, and plurality of fixed ear 14 is located at its inside edge.Should be fixedly ear 14 be formed with a screw 16 separately, by screw 18 to be locked on this casing 94.This laser generator 20 is to be fixed in this storage tank 12 in the close-fitting mode.

Because casing 94 profiles of each drilling machine 90 are not quite similar, what have is square, and what have is curved.So the material of this bogey 10 is good with light weight, easy processor, for example can be the bakelite material, has the advantage of light weight, mechanical strength height, insulating properties height and handling ease because of bakelite.Perhaps also can make, as acrylic plate by plastic material.The inboard of this bogey 10 is can cooperate its external form and corresponding in advance the shaping, and perhaps reprocessing is revised when device.

Wherein this plurality of fixed ear 16 can be the one-body molded inside edge that goes out this bogey 10 projection vertically upward.Perhaps this plurality of fixed ear 16 is can be in the form of sheets, sheet metal for example, be locked in the inboard of this load bearing seat 10 separately, so when this laser auxiliary locator of installing, after can revise cooperating according to casing 94 appearance profiles on this drill bit 92 in these bogey 10 inboards, fixedly ear 16 is fixed in the inboard of this loading plate 10 again.

See also Fig. 2, be the three-dimensional exploded view of laser generator in the utility model.Wherein the miniature laser generator is known by being familiar with this operator, be a kind of miniature laser generator as laser pen, laser generator 20 of the present utility model is that to establish a convertible luminous point in the front end of the laser generator that can produce laser spot be that the linear mirror group 24 of linear light is to produce linear light; This linear mirror group 24 has waveform lens 242, an outer ring body 244 with ccontaining and fix these waveform lens 242 in the lower end of this laser generator 20.The external form of this laser generator 20 slightly is the T type, has a housing 21 and a stopper section 22 sides provided thereon, and the size of this housing 21 is to match with this storage tank 12.

See also Fig. 3, be the combination schematic diagram of the laser auxiliary locator of the utility model drilling machine and electric drill.This laser generator 20 be close-fitting be sticked in the storage tank 12 of this load bearing seat 10.This laser generator 20 is electrically connected at a power supply 50, and the switch by this on-off controller 40 these laser generators 20 of control whether.Wherein this power supply 50 can be the power supply through the drilling machine of over commutation, perhaps also can be the circumscribed battery, and this circumscribed battery can place on this load bearing seat 10, for example is located on the corner of this load bearing seat 20 to save the space and to be convenient for changing.

See also Fig. 4, be the three-dimensional combination figure of the laser auxiliary locator of the utility model drilling machine and electric drill.Wherein this gauge tap 40 is located at the outer ledge of this load bearing seat 10.This laser generator 20 is located at this appearance of this load bearing seat 10 separately accordingly and is emitted in the groove 12, to provide a laser throw light to be projeced on the processing object 60 separately, adjust this laser throw light and form an intersection luminous point 62, and be positioned on the trajectory at tip 96 of this drill bit 92, so can allow the user be drilled with clearly in needed position.

Please refer to Fig. 4 A, be another embodiment of the bogey in the utility model.The main function of this bogey is in order to fixing this laser generator 20, and the point that its embodiment is main is the casing 94 that is to be located at the pattern that adds these drill bit 92 tops.Therefore, this bogey 10 can be that a pair of holder 11 is vertically located in boring bar tool respectively from the adjacent two sides of the casing 94 of drill bit 92 tops, or can when making, on its casing 94, fix by the one-body molded holder that is provided with for this laser generator 20.

See also Fig. 5, be the combination schematic diagram of another embodiment of laser auxiliary locator of drilling machine of the present utility model and electric drill.This laser generator 20 can be provided with a gauge tap 40 ' separately and be located at its top and be located at its inside supplying its electric power to control its switch and battery 50 ', when so installing with more convenient fast.

See also Fig. 6, be arranged at the three-dimensional combination figure of hand-operated electric drill for the utility model.The utility model also can be located on the hand-operated electric drill 90a, and wherein the fixedly ear 14 of this bogey 10 can be to be parallel to this bogey 10 and extension downwards, on the front end shell that is locked in this hand-operated electric drill 90a.

See also Fig. 7, be the ray cast schematic diagram of laser generator in the utility model.The step of its adjustment can be utilized 3 principles that form a plane:

(1) provides the processing object 60 of a smooth upper surface earlier;

(2) reduce this drill bit 92 on this processing object 60 with make one boring point, also be the crosspoint 62 that two throw lights should intersect;

(3) draw the cross linear 61 and 63 of two these boring points 62 of process then in these processing object 60 upper surfaces;

(4) respectively get a fixed point 64 and 66 on this two straight line 61 and 63, promptly produce two plane A1 and the A2 that intersect at the Z axle, this Z axle i.e. the trajectory at the tip 96 of this drill bit 92;

(5) adjust the angle of the ray cast of one of them this laser generator 20, make its tip 96 through this drill bit 92, this boring point 62, and fixed point 64, promptly definite this laser beam throws and places plane A1; And

(6) adjust the angle of the ray cast of another this laser generator 20 again, make its tip 96, this boring point 62, reach fixed point 66 through this drill bit 92, the throw light that so can guarantee this another laser generator 20 is on the A2 of plane, and so the crosspoint 62 of the throw light that produced of this laser generator 20 is the boring point 62 of drill bit 92.

Whereby, the operator does not estimate the boring point of this drill bit in order to inaccurate ocular estimate, as long as directly the centre bore of being delimited on this processing object 60 is aimed in the crosspoint 62 of this throw light, can difficulty really hole.

The characteristics that therefore can produce by the utility model and function through put in order as after:

One, can assist the operator of drilling machine to be confirmed exactly the drop point that this drilling machine is drilled with.

Two, add mode is arranged on the drilling machine and easily processing in addition, can directly be arranged at original Drilling machine on, need not improve the structure of former drilling machine, to increase auxiliary positioning function.
