In the present embodiment, five steel balls 40 outstanding ormal weight below guide plate 26.And, this steel ball 40 is made following structure, promptly, only otherwise this steel ball 40 is moved to from the active force of the primary importance antagonistic spring 41 of the state that is in outstanding ormal weight is in the second place of keeping out of the way to guide plate 26 sides, the upward facial of the following and processed parts 100 of guide plate 26 just can not contact, and keeps the gap of ormal weight between the two.The active force of spring 41 is set the intensity that only steel ball 40 does not sink under the deadweight effect of portable chamfering machine 1 for, as long as the operator pushes to processing component 100 consciously, just keeps the gap of ormal weight.
And, during the gap that keeps ormal weight, can carry out chamfer machining with the set amount littler, on the other hand than the set amount of hope, when the active force of antagonistic spring 41 makes the last facial contact of guide plate 26 and processed parts 100, can carry out chamfer machining with the set amount of described hope.Promptly, the portable chamfering machine 1 of present embodiment has following feature in configuration aspects: by the effect of spring 41 and steel ball 40, in the distance of rotating shaft direction restriction cutting tip 30 and chamfered section, as long as the operator pushes portable chamfering machine 1 consciously, the chamfering amount does not just reach set amount.To set forth in the back to the gap of ormal weight with by the relation of the chamfering amount of the set amount of hope.In addition, the active force of spring 41 in the constant mode too much of the pressing force of operator by the set amount chamfer machining time, to set the pressing force that the deadweight than portable chamfering machine 1 produces for strong a little.
On the top of plunger frame 25, be formed for the handle support 27 of fixed handle 28.Portable chamfering machine 1 is the machine of operator's use dominated by hand, and when controlling main part 2 with the right hand, the handle 28 that is mounted to level and right angle with respect to the length direction of main part 2 is suitable for controlling with left hand.In addition,, then control handle 28, control main part 2 with left hand simultaneously and also carry out operation easily with the right hand if at opposition side (left side among Fig. 2) mounting knob 28 across main part 2.
With reference to Fig. 1, Fig. 4, the recess that guide plate 26 forms with the circular by turning cylinder 7 is the semi-circular shape at center, sets below the part of main part 2 with extending.In addition, the recess that forms near the acies portion of guide plate 26 also can be made the hole shape that turning cylinder 7 connects.Guide plate 26 is fixed on the plunger frame 25 that is roughly annular by amounting to four screws 29.Described steel ball 40 along the shape of plunger frame 25 on same circle by uniformly-spaced being provided with five altogether.As mentioned above, to processed parts 100 pushing portable chamfering machines 1, carry out chamfer machining by the set amount of hope when, make to contact with the surface of processed parts 100 below guide plate 26 whole.At this moment, owing to constitute main part 2 relative housings 4 and uphold rearward, so, in five steel balls 40, be provided on below the main part 2 the easiest applying by the weight of main part 2 and the pressing force of operator's generation.Therefore, set greatlyyer to the active force of a steel ball 40 of the below that is positioned at main part 2 than the active force of other four springs.And then the size of the active force of each spring can be adjusted to suitably that five steel balls 40 sink to simultaneously when the operator pushes with hand.For example, when one of below that will be positioned at main part 2 is set as " greatly ", can be set at " little " to two active force near outer wall parts 101, two active force of position in the middle of it is set at " in ".
In addition, it is the roughly semicircle shape at center that guide plate 26 forms with turning cylinder 7, is not located at the front side of housing 4.According to this shape,, also can in the scope that does not contact housing 4, make portable chamfering machine 1 near barrier even when having barrier such as wall at the front side of portable chamfering machine 1.Thus, as shown in Figure 1, can carry out chamfer machining near the hole portion 105 of outer wall parts 101.In the portable chamfering machine 1 of present embodiment, imagination is in the chamfer machining of carrying out the hole portion 105 at peripheral part end face place from outer wall parts 101 near positions.And the diameter of hole portion that can chamfer machining is set for and hole (for example, path C1 in the figure～big footpath C2) correspondence bigger than deflector roll 20.Determine the equipping position of steel ball 40, even make that steel ball 40 does not block the hole portion that hangs over yet when the hole portion to big footpath C2 carries out chamfer machining.
In addition, as shown in Figure 4, handle 28 is adapted to its axis 28a and is offset rearward from the center (center of turning cylinder 7) of lower end axle 19.This is surplus to be arranged and control handle 28 easily because of the interval with outer wall parts 101, and simultaneously, the below that easy pushing is positioned at main part 2 is applied pretends steel ball 40 firmly most.And then, be provided in the front side that more leans on portable chamfering machine 1 than the center line 19a at and center by lower end axle 19 vertical with the length direction of main part 2 near two steel balls 40 of outer wall parts 101.This is because as far as possible support 18 is configured in the position at the center of leaning on five steel balls 40, can accept operator's pushing force well by five steel ball 40 balances, and turning cylinder 7 tilts when effectively preventing to push.
Fig. 5 is the B-B line profile of Fig. 3.Reference numeral same as described above is represented identical or equal part.As mentioned above, the gap between guide plate 26 and processed parts 100 top is formed by the steel ball 40 from guide plate 26 outstanding ormal weights.Steel ball 40 and spring 41 are contained in the accommodation section 42 that is formed at plunger frame 25.Under this state, from below during with the fastening guide plate 26 of screw 29, on spring 41, produce active force, below diagram often to steel ball 40 application of forces.The overhang of steel ball 40 can be by changing guide plate 26 peristome shape or opening size and easily adjusting.
Fig. 6 is the cutaway view of the modified example of expression projecting part.Also can replace described steel ball 40 ground to make the plunger cylindraceous 50 etc. of leading section being done glomeration from the outstanding projecting parts of guide plate 26.Even in this embodiment, in the accommodation section 52 that is formed at plunger frame 25, hold plunger 50 and spring 52, guide plate 26 is installed, thus, also be constructed so that front end outstanding ormal weight below guide plate 26 of plunger 50.In addition, in said embodiment, clip force application mechanism and projecting part at plunger frame 25 and 26 on guide plate, to constitute with screw 29 fastening and fixing simultaneously modes, for example, also can integrally formed plunger support and guide plate, simultaneously, on each accommodation section, establish lid respectively, with the independent respectively projecting part that keeps of this lid.
Fig. 7 is the ideograph of the contact site of expression cutting tip and processed parts.Reference numeral same as described above is represented identical or equal part.Fig. 7 (a) expression steel ball 40 is outstanding and be positioned at primary importance, form the state of the clearance t of ormal weight, and Fig. 7 (b) expression moves to the second place and state that clearance t disappears to diagram below pushing portable chamfering machine 1, steel ball 40.Shown in (a), the portable chamfering machine 1 of present embodiment just can keep clearance t between the facial 100a on guide plate 26 and the processed parts 100 as long as five spring 41 active forces of non resistance sink to five steel balls 40.
At this moment, if the outer peripheral face of deflector roll 20 is contacted with the side surface part 105a of hole portion 105, the blade of setting cutting tip 30 for contacts a little with chamfered section, go up one side when portable chamfering machine 1 is moved when on one side deflector roll 20 being shifted onto side surface part 105a, the chamfering amount Ri that can lack with the set amount than hope carries out the chamfer machining of inner rim portion.According to such formation,, can reduce the possibility that produces tipping by cutting tip and the impact when processed parts contact even the excessive velocities that allows cutting tip contact with chamfered section also can prevent the initial approach of processed parts deeply excessively.In addition, the operator is owing to carry out visual from beveler 1 top, so, when with deflector roll 20 patchhole portions 105, although the contact site of cutting tip 30 and processed parts 100 becomes the back of beveler 1 and can't see, but also needn't worry tipping,, can alleviate operator's burden so need not to guard against the impact ground when contacting to control portable chamfering machine 1 with the brute force more than the necessary amount.In addition, in the present embodiment, can carry out chamfer machining with chamfering amount Ri when setting steel ball 40 for and being in the first position, but the set amount that the set amount that also can contrast this hope is little carries out various changes, for example, the blade of cutting tip 30 does not contact fully with chamfered section in the time of can setting steel ball 40 for yet and be in the first position.
Secondly, shown in Fig. 7 (b), if to diagram below pushing portable chamfering machine 1, the last facial 100a of the following and processed parts 100 of guide plate 26 is contacted, then the size identical with clearance t moved to the diagram below in the position of cutting tip 30.Thus, can (for example, 3R) carry out chamfer machining by the chamfering amount R of the set amount of hope.At this moment, chamfered section has been finished the temporary transient processing of chamfering amount Ri, so the operator can not worry tipping ground pushing portable chamfering machine 1.In addition, because the supporting of the active force of portable chamfering machine 1 usefulness spring 41, so also lentamente cutting tip 30 is shifted onto chamfered section easily.
In addition, the hole portion 105 on the processed parts 100 of being located at is with fusing when being processed to form, and in the inside of machined surface side, molten metal when fusing sometimes (dregs) can be residual with the form of burr 102 (with reference to Fig. 7 (a)).Because these burr 102 upright last facial 100a that are located at processed parts 100 upward form, so owing to cause tipping easily because of guide plate 26 places the labile state that produces on the burr 102, and become the main cause that hinders guide plate 26 successfully to move.But, because the portable chamfering machine 1 of present embodiment forms the gap of ormal weight between guide plate 26 and processed parts 100,, portable chamfering machine 1 is successfully moved so burr 102 are difficult to contact with the following of guide plate 26, process temporarily.
As mentioned above, according to portable chamfering machine of the present invention, utilizing by spring energized and outstanding steel ball can carry out chamfer machining with the set amount littler than the set amount of hope during the gap that forms ormal weight on guide plate and the processed parts between the face from guide plate.On the other hand, when the antagonistic spring active force sinks to steel ball and guide plate is contacted with processed parts, can carry out chamfer machining with the set amount of hope, even so when making cutting tip with excessive velocities that chamfered section contacts, also can prevent the initial approach of processed parts deeply excessively, can prevent or reduce in when contact and big impact take place and cause cutting tip generation tipping.
In addition, the shape of the main part of portable chamfering machine or housing, support, cutting tip or formation, force application mechanism and projecting part number or formation etc. are not limited to above-mentioned embodiment, can carry out various changes.For example, the drive source of portable chamfering machine also can use the air motor that is rotated by compressed air to replace electro-motor.In addition, the shape of guide plate or the configuration of projecting part can correspondingly for example make guide plate form circle or polygon with the purposes of portable chamfering machine, and press unequal interval configuration projecting part etc.And then, when the hole that forms on wall or ceiling face or groove are used portable chamfering machine, acting force of the spring set weaken the amount that is not subjected to portable chamfering machine deadweight effect, can carry out chamfer machining by the set amount of hope with little pushing force.
