As shown in Fig. 2 guiding mechanism 101 includes guide portion 60, baseplate part 61 and storaging bucket (not shown).Storaging bucket
It is arranged on the side of guide portion 60, be used for depositing nut base 10.
Guide portion 60 includes bootstrap block 1, guiding groove 4 and u shape groove 14.Guiding groove 4 is applied in the inside of bootstrap block 1, opening
Upwards, bearing of trend is the length direction of bootstrap block 1.The width of the width of guiding groove 4 and nut base 10 is equal, and nut base 10 is firm
Can be fixed in guiding groove 4 well, and slide in guiding groove 4.
Fig. 3 is the guiding mechanism top view in embodiment 1 of the present invention.
As shown in figure 3, baseplate part 61 includes the first substrate 30 being placed in parallel and second substrate 31.First substrate 30 and
The placing direction of two substrates 31 is vertical with the length direction of bootstrap block 1.The front end of bootstrap block 1 is connected to above first substrate 30,
Rear end is connected to the top of second substrate 31.
As shown in figure 3, the bottom surface of guiding groove 4 includes leading portion 12 and back segment 13.It is in u shape that the lower section of back segment 13 is provided with section
U shape groove 14.U shape groove 14 is applied in bootstrap block 1, and opening is towards side.The width of u shape groove 14 is less than less than nut base 10
Width.U shape groove 14 has an arc section 141 and two straight sections 142, and arc section 141 is arranged oppositely with screw tap 52.
Nut base 10 is put into the top of leading portion 12 in guiding groove 4, promote nut base 10 so that nut base 10 is in guiding groove
Slide in 4.When nut base 10 moves on arc section 141, just against the screw tap 52 of top.The width of u shape groove 14 is less than spiral shell
The width of female base 10 is so that the edge of nut base 10 is carried on the both sides of u shape groove 14.When screw tap 52 moves downward, drill through nut
During base 10, u shape groove 14 can accommodate screw tap 52.Dial lower pull bar 50, start tapping process.After completing tapping process, will be tapped
Nut transfer to along the straight section 142 of u shape groove 14.
Fig. 4 is the nut structural representation in embodiment 1 of the present invention.
As shown in figure 4, nut 201 has the nut body 202 of cylinder, the inside of nut body 202 is run through making
Good screw thread 203.The lower end of nut body 202 is provided with four solder joints being spacedly distributed 204.The bottom surface of solder joint 204 and spiral shell
The bottom surface of maternal body 202 is concordant.The bottom surface of solder joint 204 surrounds a rectangle, constitutes the lower surface of nut 201.Rectangular
Width is identical with the width of guiding groove 4 so that nut 201 can just be entrenched in guiding groove 4.And the solder joint 204 stretching out makes
Obtain nut 201 to be more suitable for welding.
Embodiment effect and effect
Guiding mechanism according to the present embodiment and chasing bar, because run through inside bootstrap block thering is guiding groove, guiding groove
Width equal with the width of nut base, so nut base can just slide to the arc section of guiding groove in guiding groove, also
It is the underface of screw tap so that needing the position manufacturing screw thread corresponding with the screw tap of top, thus improve the precision of tapping.
Further, since the width of guiding groove is equal with the width of nut base, therefore female base can be just solid in guiding groove
Determine so that when tapping process plug tap is to nut base applying power, nut base will not move completely, internal screw thread presses predefined paths
Push ahead, thus improve the precision of tapping.
In addition, when nut base runs to the arc section of guiding groove, run through in the bootstrap block of lower section and have u shape groove, so screw tap
Be can continue to downwards such that it is able to ensure that nut base can drill through nut base completely after nut base, be not in internal spiral shell
The incomplete situation of stricture of vagina.
Further, since damp larger jump ring on pull bar being removed so that the damping of pull bar greatly reduces, therefore workman dials
Lower pull bar is not required to expend too many strength；And spring is provided with pull bar, can be not required to automatically by the pull bar forced back under dialling
Manually to reverse；Thus greatly reducing the working strength of workman.
<embodiment 2>
In the present embodiment 2, for identical structure in embodiment 1, give identical symbol, and omit identical to say
Bright.
Fig. 5 is the guiding mechanism side view in example 2 of the present invention.
As shown in figure 5, guiding mechanism 102 includes guide portion 62, baseplate part 61 and storaging bucket (not shown).Guide portion
62 include bootstrap block 1, guiding groove 4 and u shape groove 14.Bootstrap block 1 includes left bootstrap block 2 and right bootstrap block 3.Left bootstrap block 2 and the right side
The breach of cuboid is respectively provided with bootstrap block 3, two breach are arranged oppositely, and are collectively forming guiding groove 4.
Fig. 6 is the guiding mechanism top view in example 2 of the present invention.
As shown in fig. 6, baseplate part 61 includes the first substrate 30 being placed in parallel and second substrate 31.Before left bootstrap block 2
Two ends are connected to first substrate 30 and the left end of second substrate 31 afterwards, and link position can left and right adjustment.Right bootstrap block 3
Rear and front end is connected to first substrate 30 and the right-hand member of second substrate 31, and link position can left and right adjustment.Because a left side is drawn
The link position of guide block 2 and right bootstrap block 3 can adjust, so the width of guiding groove 4 can also adjust so that different in width
Nut base 10 can be fixed in guiding groove 4 and slide.
Guiding mechanism in the present embodiment 2 is in addition to having identical effect in embodiment 1 moreover it is possible to spiral shell by different in width
Female base guides to the lower section of screw tap.
<embodiment 3>
In the present embodiment 3, for identical structure in embodiment 1 and embodiment 2, give identical symbol, and save
Slightly identical explanation.
Fig. 7 is the guiding mechanism top view in embodiment 3 of the present invention.
