As shown in Figures 1 and 3, be formed with at the front end of base portion 31 the maintenance groove 31a being communicated with up and down.Keep groove 31a for the connecting band 52 of attachment screw 50 is passed through, be configured to, the connecting band 52 of the attachment screw 50 of carrying during by conveying attachment screw 50 imports and extracts out from upper opening from the lower openings that keeps groove 31a.Be formed with slit 31b in the front and back that keep groove 31a.Screwdriver bit enters from the slit 31b at rear to the inside that keeps groove 31a and extrudes being held in the screw 51 of holding groove 31a, and the screw of extrusion 51 is got from the slit 31b in front.
Front end arm 32 is fixed on the front end of base portion 31, has roughly L font in top view.Front end arm 32 possesses contact site 32a at front end.Contact site 32a by head part 30 when being driven into part and pressing be driven into part butt.For the related contact site 32a of present embodiment, the structure that the front end of the screw 51 to being carried by screw conveying mechanism supports is set, and opening is formed for screw 51 to squeeze into the exit wound of bullet 32b of guiding.
In the time utilizing present embodiment related nut runner 10 that screw 51 is squeezed into, under the state that pulls trigger 13 by head part 30(contact site 32a) press to being driven into part.By this operation, head part 30 is pressed into the inside of base portion 21, carry out in linkage the conveying action of attachment screw 50 and the inputting of attachment screw 50 with this action.
The screw conveying mechanism that the conveying of screw 51 is moved is as shown in Figure 3 carried out.As shown in Figure 3, this screw conveying mechanism possesses: a pair of wheel component 33, is supported on base portion 31 with the mode axle that can rotate; One-way clutch mechanism (not shown), for transmitting revolving force to wheel component 33; Roller arms 37, is connected with one-way clutch mechanism; And cylinder 38, be supported in the front end of roller arms 37 in the mode that can rotate.
Wheel component 33 is a pair of parts that the mode axle rotating is supported on the inside of head part 30.In the outer peripheral edges of wheel component 33, be equally spaced formed with otch 52a the tooth engaging with the otch 52a of the connecting band 52 of attachment screw 50.As shown in Figure 3, wheel component 33 is disposed at the position engaging with otch 52a, and is configured to by attachment screw 50 upward directions being carried along throughput direction (in Fig. 3 for clockwise) rotation.
In order to make wheel component 33 only along throughput direction rotation, one-way clutch mechanism is set.One-way clutch mechanism is configured to, and in the time that roller arms 37 moves along throughput direction, this power is transmitted to wheel component 33, in the time that roller arms 37 moves along anti-throughput direction, this power is not transmitted to wheel component 33.
In the time that head part 30 is pressed into and slides, the movement of cylinder 38 is led by guiding parts 24.That is, as shown in Figure 3, the groove that guiding parts 24 possesses to be formed through with the roughly the same width of cylinder 38 is guide part 24a, and is configured to cylinder 38 and moves along this guide part 24a.Guide part 24a obliquely tilts with respect to the direction that is pressed into of head part 30, and therefore, in the time that cylinder 38 moves along guide part 24a, roller arms 37 swings.Swing and produce revolving force by roller arms 37, carry out screw by this revolving force and carry action.Specifically, in the time that head part 30 is pressed into, roller arms 37 swings on throughput direction, and the revolving force that therefore produced passes to wheel component 33 by one-way clutch mechanism.Thus, wheel component 33, along throughput direction rotation, is carried attachment screw 50 by root.
In the time that inputting finishes and head part 30 is left from being driven into part, by the active force of spring 40, head part 30 is returned to position of readiness.Therewith in linkage, cylinder 38 turns back to the position of carrying before action along the guide part 24a of guide part 24a.Now, roller arms 37 swings, but this action is because the effect of one-way clutch is passed, and the rotation of wheel component 33 is not impacted.
In present embodiment, as shown in Figure 4, be formed with support 32c at the front end of front end arm 32.Support 32c is configured to and can supports carried screw 51.Support 32c has side wall portion 32d in both sides, form the path 32e that the front end of screw 51 can pass through between side wall portion 32d.On side wall portion 32d, be supported with vertically-guided parts 41 with the mode axle that can swing.Vertically-guided parts 41 are configured to supporting near the front end of carried screw 51.
Vertically-guided parts 41 are configured for the guide formation that the screw foremost 51 to being carried by screw conveying mechanism vertically guides.As shown in Fig. 7 A to Fig. 7 E, vertically-guided parts 41 are in top view, to be the roughly metal member made of C font, possess central guiding board 41a and vertically extend the side plate 41f of setting from the both side edges of guiding board 41a.
On guiding board 41a, be formed with the gathering sill 41b at the roughly U font of the approach axis upper shed of screw 51.Gathering sill 41b is configured to the axial region 51a of screw 51 is guided, and can be also except the shape U font roughly, can be also roughly V font, the spill such as C font roughly.Can utilize spill axial region 51a to screw 51 more than 2 to guide.For screw 51 is easily entered, the peristome 41c of gathering sill 41b expands and forms widelyr.In gathering sill 41b, the 41d of portion is with taper inclination (being described in detail later).In order to support from both sides to screw 51, the width of the interval of the sidepiece 41e of gathering sill 41b and the axial region 51a of screw 51 is roughly the same.The mode that gathering sill 41b enters into the inner side of spill with the axial region 51a of screw 51 forms, and therefore can guide screw 51 from multiple directions by guiding parts 41.
Be formed through respectively axis hole 41g at side plate 41f.In axis hole 41g, insert for vertically-guided parts 41 axles are supported to a pair of swinging axle 42 for swinging.As shown in Fig. 4～6, a pair of swinging axle 42 arranged coaxial and be inserted through respectively axis hole 41g, and be installed as in the supported hole 32f that the side wall portion 32d that is also inserted through at support 32c is formed through respectively.Front end at swinging axle 42 is installed the ring component 43 that anticreep is used.
By using in this wise two swinging axles 42 cutting apart, between swinging axle 42, be formed for the space that the head 51b of screw 51 is passed through.So, screw 51 can be passed through between swinging axle 42, thereby can make swinging axle 42 and screw 51(gathering sill 41b) approach, thus can reduce the total length of vertically-guided parts 41 and rotate circular arc, and can shorten the total length of equipment.
Vertically-guided parts 41 are by torsion spring 44 application of forces and in initial position standby.Specifically, on the spring holding section 41h that the side cuts by vertically-guided parts 41 forms, engage torsion spring 44 and carry out the application of force so that guiding board 41a with screw 51 squeeze into the substantially vertical position standby of direction.When this primary position is carried foremost screw 51 by screw conveying mechanism, as shown in Figure 8, this is foremost embedded in gathering sill 41b near the front end of the axial region 51a of screw 51.
Front end arm 32 is configured to the installation site that can adjust with respect to base portion 31.Therefore, even in the case of the screw length of used attachment screw 50 has occurred to change, also can be by vertically-guided parts 41 to guiding effectively near the leading section of carried screw 51.
Carry after action at screw, in the time that screw 51 is driven into, screw 51 is to keep the constant posture of state axial region 51a being guided by vertically-guided parts 41 vertically to be squeezed into.And in the time that the head 51b of screw 51 contacts with vertically-guided parts 41, as shown in Fig. 9 A to Fig. 9 E, vertically-guided parts 41 overcome the active force of torsion spring 44 and swing to keeping out of the way direction, the head 51b of screw 51 passes through.Therefore, just carried afterwards until the head 51b of screw 51 just will, by front, vertically guide screw 51 with identical posture by vertically-guided parts 41 from screw 51.
The guide formation related according to present embodiment, due to make gathering sill 41b in the 41d of portion tilt with taper, therefore can screw 51 be slided and carry out drawing along this inclination.Specifically, as shown in figure 10, when by attachment screw 50 upward when drawing, in the vertically-guided parts 41 of the front end of screw 51 and inclination, the 41d of portion contacts, directed along the direction of toppling over.In addition, owing to applying power along the direction also swinging with respect to vertically-guided parts 41, therefore vertically-guided parts 41 swing to keeping out of the way direction.So, by make vertically-guided parts 41 in the 41d of portion tilt, can swimmingly screw 51 be taken off with nut runner 10 from attachment screw.
In the present embodiment, as shown in figure 11, the surface of guiding board 41a with the face angulation θ 1 by the 41d of portion and axis hole 41g in gathering sill 41b below 45 degree.By being set as this angle, screw 51 can be remained vertically, and in the time that the head 51b of screw 51 passes through, vertically-guided parts 41 become easy swing.; when having served as the earth and having increased this angle (if being more than 45 degree like that shown in the θ 2 of for example Figure 11); when screw 51 is transferred, by the power applying along the direction of D2, vertically-guided parts 41 are easily swung, the head 51b of screw 51 by time the power that is difficult to by applying along the direction of D1 vertically-guided parts 41 are swung.On the other hand, by must be less by angle initialization as present embodiment, when screw 51 is transferred, even if the direction along D2 applies power, vertically-guided parts 41 also do not swing, can vertically support screw 51, the head 51b of screw 51 by time and while applying power along the direction of D1, even less power, vertically-guided parts 41 also can swing.
In addition, because gathering sill 41b is formed as roughly U font, that the axial region 51a of the screw 51 therefore carried contacts is the inner 41d of portion.But in the time that the head 51b of screw 51 passes through, the sidepiece 41e of gathering sill 41b contacts with head 51b.Different due to from the distance of swinging axle 42, are transferred with screw 51 and gathering sill 41b are applied compared with the situation of power, screw head 51b by time when the sidepiece 41e of gathering sill 41b is applied to power, can vertically-guided parts 41 be swung with less power.
As mentioned above, according to present embodiment, vertically-guided parts 41 possess the gathering sill 41b of the roughly U font that the axial region 51a of screw 51 is guided, when carried foremost screw 51 by screw conveying mechanism, this foremost the axial region 51a of screw 51 be embedded in gathering sill 41b, and by be embedded into screw foremost 51 after above-mentioned gathering sill 41b squeeze into and make this foremost screw 51 head 51b by time, vertically-guided parts 41 swing to keeping out of the way direction.,, owing to supporting the screw 51 of carrying and the posture of screw 51 is guided by the gathering sill 41b of U font roughly, therefore can guide the posture of the screw 51 of reaching the last.Therefore,, owing to screw 51 vertically being led reaching the last, therefore can prevent the situation that attachment screw 50 is excessive because inertia is transferred, thereby can vertically guide screw 51.And, because screw in inputting 51 is also vertically continued guiding, therefore good up rightness can be kept to the final.And, due to the head 51b of screw 51 by time vertically-guided parts 41 swing to keeping out of the way direction, therefore also can make the head 51b of screw 51 pass through out of questionly.
In addition, because the vertically-guided parts 41 by cantilever shape guide the posture of screw 51, therefore do not need vertically-guided parts to be made as box shape.Therefore, the easily inside of Visual Confirmation mechanism, in addition, because hand also easily enters into inside, therefore also easily carries out screw 51 and removes screw operation while stopping up.In addition, because vertically-guided parts are not box shape, therefore can reduce front equipment end, and easily in the time that screw is constructed, aim at.
In addition, owing to can passing through the axial region 51a of vertically-guided parts 41 supporting screws 51, therefore do not need the length for vertically-guided parts 41 are set at the front end of screw 51.Therefore, head part 30 can be shortened, thereby the total length of equipment can be shortened.
In addition, because structure is comparatively simple, therefore can be by the manufacture component at an easy rate such as punch process.
In addition, due to make gathering sill 41b in the 41d of portion tilt with taper, therefore in the time taking off screw 51 from equipment, the 41d of portion drawing screw 51 in can tilting along taper, in addition, because vertically-guided parts 41 are because this operation swings, therefore can easily screw 51 be taken off.
In addition, a pair of swinging axle 42 by arranged coaxial carries out axle supporting to vertically-guided parts 41, can between a pair of swinging axle 42, pass through, therefore thereby be formed as screw 51, the rotation circular arc of vertically-guided parts 41 can be reduced, and the total length of equipment can be further shortened.
