The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further detailed description.
See also Fig. 1, a kind of shearing tool 1 that is applied on the swing power tool is applicable to shearing manipulation.This swing power power tool is appointed as label 10, comprises tubular casing 11 and the head capsule 12 that roughly is the angle setting that is connected casing 11 front ends (left side is defined as front end among Fig. 1), and output shaft 13 extends in head capsule 12.As shown in Figure 2, the free end of this output shaft 13 is regular hexagon, and has axial line X.The free end of output shaft 13 flange that also is formed with ring-type 131 radially.
Please continue to consult Fig. 1, in the casing 11 of this swing power tool 10, be provided with the transmission component (figure does not show) of motor that driving force is provided (figure does not show) and driving torque, be connected with cable 14, be used for electric power being provided to motor in the rear end of casing 11.After motor was connected and produced driving force, the moment of torsion of driving force was passed to output shaft 13 through transmission component.Under the effect of moment of torsion, output shaft 13 is done oscillating motion around axial line X, and swaying direction is shown in the double-head arrow A-A direction among Fig. 1.
See also Fig. 3 to Fig. 5, shearing tool 1 is the additional element that is connected on the head capsule 12, belongs to dismountable annex that is connected on the head capsule 12.This shearing tool 1 comprise Connection Block 2, the capping 3 fixing, be connected the ledger-plate 4 on the Connection Block 2 and be housed in Connection Block 2 with respect to Connection Block 2 and capping 3 between the cutting blade 5 movable with respect to ledger-plate 4.
See also Fig. 6 and Fig. 7, the latter half of the shape of locating cover 22 and head capsule 12 is roughly suitable, and its longitudinally along head capsule 12 is formed with U type guard shield 221, and is same, is formed with arc guard shield 222 along the vertical direction of head capsule 12.Like this, this locating cover 22 can be coated on the below of head capsule 12, because the acting in conjunction of U type guard shield 221 and arc guard shield 222, Connection Block 2 can be positioned at the below of head capsule 12 fast, and is not easy to come off.
Please continue to consult Fig. 5; Ledger-plate 4 is fixedly coupled on Connection Block 2; Comprise connecting portion 41 and stationary knife head 42; Through kink 43 connections connecting portion 41 and stationary knife head 42 are laid respectively in the different plane between connecting portion 41 and the stationary knife head 42, the purpose of doing like this is in order to reserve the installation site for cutting blade 5.On connecting portion 41, divide other to be provided with bolt hole 44 and locating hole 45, and bolt block 24 pass bolt hole 44 and ledger-plate 4 is fixedly connected on the Connection Block 2, reference column 25 passes 45 pairs of ledger-plates 4 of locating hole and plays the assist location effect.On stationary knife head 42, be formed with cutting edge 46 towards the direction of Connection Block 2.
Please consult Fig. 8 in the lump; Capping 3 is circular; Bolt block 24 on the corresponding Connection Block 2 is provided with some screws 34, and formation is stepped on end face, comprises first groove 31 that is used to accommodate cutting blade 5; With second groove 32 that is used to accommodate ledger-plate 4, and the cannelure 33 that is used to accommodate the installation portion 51 of cutting blade 5.Need to prove that the width D 1 of first groove 31 is greater than the width d of the connecting rod 53 of cutting blade 5, thereby the swing of cutting blade 5 is limited within the width D 1; The width D 2 of second groove 32 is slightly larger than the connecting portion 41 of ledger-plate 4; The diameter D3 of cannelure 33 is slightly larger than the installation portion 51 of cutting blade 5.In addition, in capping 3, also be provided with the locating slot 35 that is used to locate, supply the reference column 25 on the Connection Block 2 to insert fixing.
When using, the user is placed on cutting blade 5 on the Connection Block 2, and at this moment, dynamic cutter head 52 is between the connecting portion 41 of stationary knife head 42 and ledger-plate 4, and the installation portion 51 of cutting blade 5 contacts with race ring 23 end faces on the Connection Block 2.The user is with capping 3 corresponding installations then; Be that reference column 25 inserts locating slot 35 in the capping 3; The connecting rod 53 of cutting blade 5 is housed in first groove 31 of capping 3, the bolt block 24 on the screw 34 corresponding Connection Blocks 2, and by screw capping 3 is tightened and to be fixed on the Connection Block 2.Like this, when cutting blade 5 is swung with respect to ledger-plate 4, the swing that the installation portion 51 of cutting blade 5 and the race ring on the Connection Block 2 23 produce on the end faces, amplitude of fluctuation is subject to the width D 1 of first groove 31 in the capping 3.
See also Fig. 9 to Figure 10 and Figure 14, when this shearing tool 1 is connected swing 10 last times of power tool, the installing hole 54 on the cutting blade 5 connects together with output shaft 13, and race ring 23 connects with flange 131 on the output shaft 13.When output shaft 13 is done oscillating motion, can drive the cutting blade 5 that is connected on the output shaft 13 and also do oscillating motion, simultaneously, 4 of ledger-plates are fixed. Cutting edge 46,56 staggered contacting on stationary knife head 42 between the two and the dynamic cutter head 52, and dynamic cutter head 52 is with respect to 42 swings of stationary knife head, thus realize shear action.
See also Figure 11 to Figure 13, be the operation principle sketch map of this shearing tool.Shown in figure 12; When swing power tool 10 did not start, output shaft 13 was not done oscillating motion, thereby; The cutting blade 5 that connects output shaft 13 is not done oscillating motion equally and is remained on initial position, the position when promptly as shown in Figure 12 cutting blade 5 and the cutting edge angle between the ledger-plate 4 is α 1.
Shown in figure 11, when output shaft 13 is swung clockwise, cutting blade 5 will be done the clockwise direction swing around axial line X; Its cutting edge 56 produces angular displacement with respect to ledger-plate 4; Thereby, make the cutting edge angle between the two be extended to α 2, constitute the operation of opening in the shearing motion.
And for example shown in Figure 13; When output shaft 13 generations are swung in the other direction, when promptly output shaft 13 is done counter-clockwise swing, cutting blade 5 will be done swing counterclockwise around axial line; Its cutting edge 56 produces angular displacement with respect to ledger-plate 4; Thereby, make the cutting edge angle between the two be contracted to α 3, constitute the closed procedure in the shearing motion.
Certainly, the angle here only is in order to be beneficial to the clearly sign that explanation is taked, and is exactly to adopt such angle setting but be not defined in, and it can also be other angles that realize shear action.
Along with the swing of output shaft 13, it drives cutting blade 5 and also does swing, and amplitude of fluctuation is gone round and begun again within above-mentioned angular range, realizes shear action.
