The specific embodiment
The invention discloses a kind of guider that is used on the electric planer.
Referring to shown in Figure 1, guider 7 is arranged on the right side of electric planer 30, and guider 7 also can be arranged on the left side of electric planer 30.
Electric planer 30 has housing 1, is arranged on the main handle 2 on the housing 1, is arranged on the adjusting knob 4 of housing 1 front portion, is arranged on the base plate 3 of housing 1 below.Base plate 3 comprise noseplate 5 and the back base plate 6, in preferred embodiment of the present invention, back base plate 6 along B to width greater than housing 1 along B to width.The width of back base plate 6 also can be less than or equal to the width of housing 1.
Rotation adjusting knob 4 can be regulated noseplate 5 and move up and down with respect to housing 1, thereby regulates the ploughing depth of electric planer 30.
To shown in Figure 3, guider 7 of the present invention comprises flat guide 8 referring to Fig. 1, and with guide 8 vertically disposed flat support members 9, in preferred embodiment of the present invention, support member 9 is wholely set with guide 8.
Preferably, the cross section of guide 8 and support member 9 is rectangle.Support member 9 along B to width and along A to length respectively with guide 8 along C to width and along A to equal in length.
Support member 9 and guide 8 are made by light material, such as aluminium, plastics etc.
Guide 8 has guide part 11, and the face at guide part 11 places is parallel with the face at support member 9 places.
Handle 10 is arranged on the guide 8.Handle 10 comprises grip part 12 and connecting portion 13.Connecting portion 13 is for being vertically set on the elongated cylinder on the guide 8, and the end that connecting portion 13 deviates from guide 8 is fixed with columned grip part 12, and preferred, the axis of grip part 12 is parallel with the face at guide 8 places.The axis of grip part 12 also can with the Plane intersects at guide 8 places.Grip part 12 also can be for other shape, and such as the opposite sex, the cross section is rectangle or the like.Grip part 12 links to each other with guide 8 by connecting portion 13.
Connecting portion 13 along B to length more than or equal to support member 9 along B to width, thereby after guaranteeing that guider 7 is fixed on the housing 1, grip part 12 protrudes in support portion 9, the operator can be very smooth, gripping handle 10 easily when operation.
Referring to shown in Figure 3, the upper surface 20 of T shape projection 14 self-supporting parts 9 extends, T shape projection 14 along B to running through support member 9.Projection 14 is provided with screwed hole 17.
Back base plate 6 is provided with and is used for the T connected in star 15 that connects with projection 14.T connected in star 15 is along B base plate 6 after running through.Groove 15 has inner surface 26.
According to those of ordinary skills as can be known, projection 14 can be arranged on the base plate 6 of back, and groove 15 can be arranged on the support member 9.Projection 14 and groove 15 also can be other shape, such as dovetail shaped, rectangle etc.
Guider 7 also comprises hook knob 16, and hook knob 16 is locked in support member 9 on the base plate 6 of back.
When being installed to guider 7 on the housing 1, at first T shape projection 14 is inserted T connected in star 15, the upper surface 20 of support member 9 is fitted with the lower surface 22 of back base plate 6, at this moment, makes progress at A, and guider 7 just can not produce displacement with respect to housing 1; Then hook knob 16 is screwed in screwed hole 17 until the inner surface 26 that supports to T connected in star 15, at this moment, make progress at B, guider 7 can not produce displacement with respect to housing 1, and guider 7 just is fixed on the housing 1.Further referring to shown in Figure 2, after guider 7 is installed on the housing 1, guide 8 and base plate 3 vertical settings.
Above-mentioned guider 7 connects the mode that is installed on the housing 1 by base plate 6 behind support member 9 and the electric planer, and is fixed, accurate positioning, electric planer 30 in the course of the work, guide 8 can remain vertical setting with base plate 3.
Referring to Fig. 1, shown in Figure 2, workpiece 21 has to be processed 23 and datum level 24, and the angle α between to be processed 23 and the datum level 24 is an acute angle.Angle α between to be processed 23 and the datum level 24 also can be the obtuse angle.
During work, electric planer 30 is placed on the workpiece 21, the operator is gripping handle 12 on the other hand, guide 8 is pressed on the datum level 24 of workpiece 21, makes the side surface 19 of guide 8 and the datum level 24 of workpiece fit, another hand grips main handle 2, electric planer 30 is pressed on to be processed 23, and mobile electric planer 30 makes guider 7 slide along datum level 24, planing tool 18 just can be treated machined surface 23 and plane, and realizes that machined surface 27 is vertical with datum level 24.
Referring to shown in Figure 4, when to be processed 23 of workpiece 21 is curved surface, can utilize auxiliary guide member 25 to cooperate with guider 7, Machining of Curved Surface is become to face directly.
Auxiliary guide member 25 have upper surface 28 and with the vertically disposed side surface 29 of upper surface, upper surface 28 is used for cooperating with the guide part 11 of guider 7, side surface 29 is used for cooperating with datum level 24.
During work, auxiliary guide member 25 is fixed on the workpiece 21, makes side surface 29 and workpiece datum level 24 fit.The operator is gripping handle 10 on the other hand, guide 8 is pressed on the datum level 24, another hand grips main handle, electric planer 30 is pressed on to be processed 23, mobile electric planer 30, make guider 7 slide along datum level 24, planing tool 18 is just along the direction towards auxiliary guide member 25, and to be processed 23 of planing workpiece fitted until the guide part 11 and the upper surface 28 of auxiliary guide member 25 of guider 7, at this moment, mobile electric planer 30 makes guider 7 slide along workpiece datum level 24, and guide part 11 slides along upper surface 28, just can realize that workpiece machined surface 27 is vertical with workpiece datum level 24, and parallel with the upper surface 28 of auxiliary guide member 25.
