Under state shown in Fig. 5 (C), by squeeze into beat the lip part 102 hit tapered cup nut 1 above, tapered cup nut 1 is driven in the hole 3 that is connected member 4 lip part 102 contact hole stepped part 302 and stopping.
Because the hole tapered portion 301 in hole 3 and the tapered portion of tapered cup nut 1 101 engage, the axle center in hole 3 is consistent with the axle center of tapered cup nut 1.Therefore, by being connected the Surface Vertical landform pore-forming 3 of member 4 relatively, make the axle center and the Surface Vertical that is connected member 4 of tapered cup nut 1.Consistent with the axle center of the tapered portion of tapered cup nut 1 by the axle center that makes the female thread 104 that is formed in the tapered cup nut 1, the central shaft that can easily make female thread 104 is perpendicular to the surface that is connected member 4.
In addition, on the top of tapered cup nut 1, by lip part 102 is set, make tapered cup nut 1 lip part 102 following 103 contact holes 3 hole stepped part 302 and stop.In the occasion that does not have lip part 102, tapered cup nut 1 slips in the hole 3, aluminum alloy system to be connected member 4 softer than the tapered cup nut 1 of stainless steel, significantly be out of shape so be connected the hole 3 of member 4.For this reason, as this form of implementation,, can prevent slipping into of tapered cup nut 1, prevent the distortion in hole 3 by lip part 102 being set at tapered cup nut 1.
Under state shown in Fig. 5 (D), tapered cup nut 1 is remained in by frictional force and is connected member 4, and the result need be with the value of interference fit F of good accuracy control for hole 3.For this reason, with the tapered portion 101 of good precision processing tapered cup nut 1 and the hole tapered portion 301 and the hole stepped part 302 of machining hole 3 is very important simultaneously.The precision that is used for the tapered portion processing sword 201 of the formed drill 2 of machining hole tapered portion 301 and hole stepped part 302 simultaneously and stepped part processing sword 202 these two swords has been stipulated the interference fit precision of tapered cup nut.That is, Yi Bian tapered cup nut 1 in the way of squeezing on one side expanded hole 3 advance, when lip part 102 touches the hole stepped part 302 in hole 3, stop, so need be with the hole tapered portion 301 and the hole stepped part 302 in high-precision processing hole 3.
In addition, in order to obtain stable joint construction, also need manage the value of interference fit F of tapered cup nut 1 with highi degree of accuracy.For example, in the tapered cup nut of making corresponding to the M4 screw of Fig. 2 explanation, the maximum diameter d 1 of tapered portion 101 be 6mm, tolerance range at this moment is+and 0.02mm～+ 0.04mm.That is, average tolerance is+0.03mm.On the other hand, the maximum diameter of tapered portion processing sword 201 of the formed drill that is shown in Fig. 32 that forms the hole tapered portion 301 in hole 3 is 6mm, the tolerance range of this moment is-and 0.01mm～+ 0mm.That is, average tolerance is-0.05mm.Like this, the maximum diameter of the hole tapered portion 301 in the hole 3 that is formed by tapered portion processing sword 201 is than the little 0.035mm of maximum diameter of the tapered portion 101 of tapered cup nut 1.The taper value of the taper value of the tapered portion processing sword 201 of formed drill 2 and the tapered portion 101 of tapered cup nut 1 equates, all is 1/20.As a result, value of interference fit F is 0.7mm (=0.035mm * 20).That is, by tapered portion 101 with good accuracy processing tapered cup nut 1, and the hole tapered portion 301 and the hole stepped part 302 of while machining hole 3, can manage the value of interference fit of hole 3 accurately for tapered cup nut 1.
Shown in Fig. 5 (E), when connection has the 2nd of hole 501 when being connected member 5, dispose the 2nd at the 1st back side that is connected member 4 of having squeezed into tapered cup nut 1 and be connected member 5, fastening with screw 6.Be connected member 4 the 1st and be the occasion of aluminum alloy system, for example, the 2nd is connected member for the printed circuit board (PCB) of component is installed.Apply load at tapered cup nut 1 along tapered portion connecting direction thus, so tapered cup nut 1 is not fully from being connected the danger that member 4 becomes flexible.In addition, when will be from the hole 3 hole tapered portion 301 when taking off tapered cup nut 1, as long as under the state that unclamps screw 6, knock the head of screw 6 lightly, can simply it be pulled down.
Made by stainless steel corresponding to the tapered cup nut 1 that the screw of M4 is made, in addition, the 1st connector element 4 is made by aluminum alloy.Both taper values are 1/20, and the maximum outside diameter d1 of the tapered portion 101 by making tapered cup nut 1 does multiple variation, thereby situation is squeezed in the value of interference fit investigation that changes tapered portion.As a result, though the value of interference fit of tapered portion changes between 0.01mm～0.07mm, all occasions all can be squeezed into simply, and in addition, its hold mode is also very good, can firmly not connect pivotally fully.
Taper value is most important key point in the present invention.In order to make tapered cup nut be easy to squeeze into and be held reliably after squeezing into, angle at least must be less than friction angle.Squeeze into easy degree and to keep easy degree as considering, then tapering 1/20 is extraordinary value, but as scope applicatory, as then better between 1/50～1/10, and arrives 1/7～1/6 also applicable.Yet, squeeze into power greatly and also increase along with tapering becomes, in addition, as further surpassing 1/6, can produce the phenomenon that the object squeezed into flies out.
The present invention does not limit the screw that is applicable to M4, can suitably use to the screw of this degree of M2～M10 yet.The better size of the tapered cup nut in these scopes is as follows.
When the external diameter (mm) of screw was d0, the maximum diameter d 1 of the tapered portion 101 of tapered cup nut 1 existed
d1＝(1.1～2.0)×d0
Scope the time better.Particularly exist
d1＝(1.2～1.5)×d0
Scope the time better.
In addition, the outside diameter d 2 of the lip part 102 of tapered cup nut 1 exists
d2＝d0+(0.5～3.0)
Scope in the time better.
In addition, the lip part thickness t exists
t＝0.5～3.0mm
Scope the time better.
The taper value of tapered portion 101 as described above, when
Taper value=1/50～1/10
Scope the time better.
The total length L of tapered cup nut 1 exists
L＝(1～3)×d0
Scope the time better.
The pass of the value of interference fit F of tapered portion and the maximum diameter d 1 of tapered portion 101 ties up to
F＝(2～20％)×d1
Scope the time better.
Above-mentioned value is the value of the occasion of connection soft metal (aluminum alloy, fine copper etc.).In the occasion of material softer (for example timber and plastics etc.), making tapering is 1/30～1/5, and the width d3 that makes flange is 1～4mm, and it is more favourable then to get bigger slightly value like this.Like this, increase, flange width is increased,, can prevent from that tapered cup nut from sinking to to be connected in the member when being connected 2 with screw with tapered cup nut when being connected member by making taper value.
As the material of tapered cup nut, in above-mentioned example, used stainless steel, but material is not limited thereto, so long as can make multiple choices than being connected the hard material of member.For aluminum alloy and copper material, except stainless steel, for example can use iron and steel (SS material, carbon steel, light alloy steel, modified material (quenching is annealed to about HRC15～25)) etc.In addition, as nonferrous materials, can use bronze and brass etc.
In addition, being connected the occasion that member is a timber,, can use plastics and aluminium etc. as the material of tapered cup nut.Being connected the occasion that member is plastics,, can use aluminium, stainless steel, iron and steel, phosphor bronze, brass etc. as the material of tapered cup nut.Being connected the occasion that member is an iron and steel,, can use Chilled Hardened Steel (supersteel) as the tapered cup nut material.
The material of tapered cup nut there is no need certain material harder than the material that is connected member that use, and also can use the material of same degree hardness.That is, be connected the occasion that member is an iron and steel,, can use iron and steel as the material of tapered cup nut.
In addition, high hardness materials such as relative metal pattern are considered wearing and tearing and exchangeability, also can use the tapered cup nut of the material lower than mother metal hardness.
As described above, in having the hole that is connected member 43 of hole tapered portion 301, put into tapered cup nut 1, from lip part 102 sides of tapered cup nut 1 it is squeezed into, can easily be connected the tapered cup nut 1 that member 4 fixedly has female thread 104 relatively, so can improve operation.
In addition, the tapered portion 101 by engaging tapered cup nut 1 and the hole tapered portion 301 in hole 3, the female thread 104 that can easily prevent to be formed at tapered cup nut 1 is connected the axle offset of member relatively.
In addition, lip part 102 is set by top at tapered cup nut 1, make tapered cup nut 1 lip part 102 following 103 contact holes 3 stepped part 302 and stop.Therefore, 3 amounts of floating are value of interference fit from the hole to drop into the lip part 102 of the state inferior pyramidal nut 1 in the hole 3 by management tapered cup nut 1, can make tapered cup nut 1 is certain for the amount of squeezing in hole 3, and it is certain making the hole 3 and the frictional force of tapered cup nut 1, and the retention force that makes both is certain.
In this form of implementation, use one to have the formed drill 2 of tapered portion processing sword 201 and stepped part processing sword 202, form the hole tapered portion 301 and the hole stepped part 302 in hole 3, so that the management of value of interference fit becomes is easy.
In addition, lip part 102 is set, makes following 103 the touching the hole stepped part 302 in hole 3 and stop of lip part 102 of tapered cup nut 1 by top at tapered cup nut 1.In the occasion that does not have lip part 102, tapered cup nut 1 slips in the hole 3, aluminum alloy system to be connected member 4 softer than the tapered cup nut 1 of stainless steel, significantly be out of shape so be connected the hole 3 of member 4.Different therewith, by as this form of implementation, lip part 102 being set, can prevent that tapered cup nut 1 from slipping at tapered cup nut 1, prevent hole 3 distortion.
For tapered cup nut 1, apply power by shrinking side from tapered portion 101, promptly by the loosening slightly screw 6 and the top of beaing the screw 6 that is connected in female thread 104, can easily remove engaging of tapered cup nut 1 and hole 3, the mounting or dismounting of tapered cup nut are carried out easily.
Therefore, in the occasion that is used in the serious position of thread abrasion and screw thread damage, can easily carry out the replacing of tapered cup nut.
In addition, even in the discarded occasion that is connected member owing to can easily pull down tapered cup nut, thus can discard respectively material different be connected member and tapered cup nut, help environmental protection.
In addition, the tapered cup nut of pulling down is recycling, so can effectively utilize resource.
In addition, in such in the hole that is connected member formation, the inserting in the method for stiffener of prior art, for the such small screw thread of M1～M3, because the aperture is too little, so can not use.Different therewith, in this form of implementation, as long as form the female thread corresponding simply, so also applicable for small screw thread with the screw of M1～M3 in the inside of tapered cup nut.
Be used for the tapered cup nut of this form of implementation is driven into the formation of using hammer squeezed into that is formed in the hole that is connected member according to Fig. 6 and Fig. 7 explanation below.
Fig. 6 squeezes into the schematic partial sectional view of hammering into shape for the tapered cup nut of an embodiment of the present invention, and Fig. 7 is the partial plan layout of Fig. 6.
Squeeze into hammer 7 and grasp use.Squeeze into hammer 7 the power of squeezing into and produce by spring, squeeze into finish after, utilize the power of Air Force as pressure spring.
At first explanation is squeezed into all formations of hammering 7 into shape according to Fig. 6.
Squeeze into hammer 7 body 701 to cylindric the size of holding for available palm.In the inner space of body 701, piston 702 can be kept up or down along the direction of arrow.Lower part of piston bar 703 protrudes into the outside from the bottom through hole of body 701, with the front end of lower pole 703 tapered cup nut is squeezed into.Near the cardinal principle central authorities of the upper bar 704 of piston 702, form notch 705.When piston 702 was mobile towards the top, notch 705 engaged with the front end moving block 707 of stopper 706, stops to move up and down of piston 702.Moving block 707 is pushed towards the arrow B direction by pressure spring 708.In addition, as shown in Figure 7,,, can stop to move up and down of piston 702 by engage the notch 705 of pistons 702 at this V-shaped valley 709 at the front end formation V-shaped valley 709 of moving block 707.
Form a plurality of relief openings 710 in the bottom of body 701.In addition, configuration can be along the dividing plate 712 of arrow C direction slip in the air chamber 711 that is formed at piston 702 bottoms of body 701 inside.Form a plurality of relief openings 713 at dividing plate 712.By along arrow C direction traverse 712, but connected sum cuts off the relief opening 710 of body 701 and the relief opening 713 of dividing plate 712.
The switch 714 of being located at body 701 tops by hand that slides through of dividing plate 712 carries out.Switch 714 is connected by lever 715 with dividing plate 712.Therefore, move towards arrow D direction, dividing plate 712 is slided towards left-hand, be communicated with the relief opening 710 of body 701 and the relief opening 713 of dividing plate 712 by operating switch 714.In addition, when switch 714 when arrow D direction moves, the right-hand member of switch 714 engages with the left end of the V-shaped valley 709 of moving block 707, and moving block 707 is slided towards dextrad, thereby can remove the joint of notch 705 and V-shaped valley 709.
At lever 715 and 701 configurations of body helical spring 716.Therefore, hold the hand of switch 714, make lever 715 towards the revolution of arrow E direction, thereby dividing plate 712 is slided towards dextrad, cut off the relief opening 710 of body 701 and the relief opening 713 of dividing plate 712 by relieving.
Between on the inner space of the top of piston 702 and body 701 pressure spring 717 is set.Pressure spring 717 applies elastic force towards the direction of arrow to piston 702.
In addition, the air chamber 711 in body 701 inside imports pressurized air from air supply opening 718.Periphery at piston 702 is installed O-ring seals 719, prevents that the pressurized air in the air chamber 718 from leaking towards the top.
The following describes squeezing into of this form of implementation with the action of hammering 7 into shape.
Under illustrated state, the relief opening 710 of body 701 and the relief opening 713 of dividing plate 712 are not communicated with.Therefore, when from air supply opening 718 importing pressurized air, the elastic force of piston 702 resistance pressure springs 717 rises towards the arrow G direction.At this moment, the upper bar 704 of piston 702 also rises, and the notch 705 of upper bar 704 engages with the V-shaped valley 709 of moving block 707, and the rising of piston 702 stops.
When squeezing into tapered cup nut, holding switch 714 with palm with squeezing into hammer 7.At this moment, switch 714 moves towards arrow D direction, and by lever 715 dividing plate 712 is slided towards left-hand, is communicated with the relief opening 710 of body 701 and the relief opening 713 of dividing plate 712.As a result, the pressurized air in the air chamber 711 is discharged to the outside from relief opening 713.Here, the basal area than air supply opening 718 is big fully for basal area by making a plurality of relief openings 710, pressurized air in the air chamber 711 is discharged to the outside rapidly, and discharges the pressurized air that imports from air supply opening 718, make the pressure of air chamber 711 become barometric pressure substantially from relief opening 710.
Switch 714 slides towards arrow D direction, and the right-hand member of switch 714 is engaged with the left end of the V-shaped valley 709 of moving block 707, makes moving block 707 towards the dextrad slip, thus the engaging of releasing notch 705 and V-shaped valley 709.717 pairs of pistons 702 of pressure spring apply elastic force, so piston 702 slides towards arrow F direction, the front end of lower pole 703 also slides towards the below.Therefore, contact on tapered cup nut, can squeeze into tapered cup nut by the front end pushing that makes lower pole 703.
After end is squeezed in 1 time of tapered cup nut, by decontroling switch 714, dividing plate 713 is slided towards dextrad, remove the connection of the relief opening 713 of the relief opening 710 of body 701 and dividing plate 712.As a result, the elastic force of being revolted pressure spring 717 by the pressurized air that imports from air supply opening 718 makes piston 702 rise towards the arrow G direction, and the notch 705 of upper bar 704 engages with the V-shaped valley 709 of moving block 707, and the rising of piston 702 is stopped.
Carry out above action repeatedly, by the operation of switch 714, can utilize the elastic force of pressure spring 717 to squeeze into tapered cup nut, in addition, the piston 702 that can utilize pressurized air to be used in to squeeze into automatically rises to primary position.
Because behind the pressurized air of chamber 711 that deflates at first, sliding piston 702 is so the power of squeezing into of piston is by the elastic force decision of pressure spring 717.Therefore, the power of squeezing into of piston can be by changing the elastic force change of pressure spring 717.
As squeezing into the such hammer of tapered cup nut, with the occasion of pressurized air as the pneumatic hammer etc. of squeezing into power self, because it is strong excessively to squeeze into power, so, after above squeezing into tapered cup nut, the front end of lower part of piston bar carries out rebound action on tapered cup nut, so exist the lower part of piston bar to hit the danger that member, damage are connected member that is connected beyond the tapered cup nut.Different therewith, as this form of implementation,,, can set than the little power of squeezing into of compression air, so can prevent the damage that is connected member of beating and causing as described above by using the compressive force of spring as the power of squeezing into of tapered cup nut.
In addition, when the elastic force of resistance pressure spring rose piston with hand, its operation is not easy, and was different therewith, in the piston uphill process, can make operation also become simple by using pressurized air.
Below, all formations of the system that squeezes into automatically of the tapered cup nut of this form of implementation are described according to Fig. 8.
Fig. 8 is for being driven into the tapered cup nut of an embodiment of the present invention automatically the explanatory drawing of the system that is connected member.

On conveyor 8, form the opening of certain intervals.The opening of conveyor 8 place randomly tapered cup nut 1A, 1B ..., 1G ..., transport towards arrow H direction.
Whether posture determine sensor 9 is configured in the below of conveyor 8, transport with correct body position and carry out posture and judge transported the tapered cup nut that comes 1 by conveyor 8.As posture determine sensor 9, for example use proximity sense.In the occasion that as tapered cup nut 1A, 1F, 1G, is inserted into the opening of conveyor 8 with correct posture, because posture determine sensor 9 is that the distance of proximity sense and tapered cup nut 1 is approaching, so can obtain the output signal of the situation of correct body position from proximity sense.In contrast, in the occasion that as tapered cup nut 1B, 1C, 1D, 1E, does not have at the correct mounting tapered cup nut 1 of the opening of conveyor 8, because being the distance of proximity sense and tapered cup nut 1, posture determine sensor 9 keeps off, so can judge it is not correct body position from proximity sense.
The revolution action of manipulator control gear 11 control manipulators 12 and be installed on the action of suction feed head 14 of the attraction cylinder 13 of manipulator 12 front ends.Manipulator control gear 11 is according to the posture decision signal action of posture determine sensor 9.In the normal occasion of posture of the tapered cup nut of institute's mounting, behind posture determine sensor 9 input OK signals, when being transported to the positive upper/lower positions of suction feed head 14, this tapered cup nut 1 makes to attract cylinder 13 actions, fall suction feed head 14.Next, attract conical head 1, suction feed head 14 is risen with suction feed head 14.
Then, make manipulator 12 action, mobile tapered cup nut 1 on the opening that is connected member 4.Be connected member 4 mountings on the platform that can move, can be positioned position under the suction feed head 14 respectively being pre-formed in a plurality of openings that are connected member 4 along the X-Y both direction.Position above the opening that is connected member 4 by open vacuum, can make tapered cup nut 1 drop in the opening.Here, be formed at the opening that is connected member 4 and as illustrating, have the hole tapered portion with Fig. 4, in addition, as illustrated with Fig. 1, tapered cup nut 1 has tapered portion in periphery, so,, can easily shown in Fig. 5 (C), like that tapered cup nut 1 be inserted in the opening that is connected member 4 as long as on opening, fall tapered cup nut 1.Be formed at a plurality of openings that are connected member 4 by tapered cup nut is inserted into respectively, finish the insertion operation of tapered cup nut.
Next, will be connected member 4 is transported to and is pressed into the station.To be connected member 4 mountings to the platform that can move being pressed into the station, can navigate to position under the piston 16 of depressing cylinder 15 respectively being pre-formed in a plurality of openings that are connected member 4 along X-Y two directions.Be pressed into cylinder 15 actions by making, piston 16 descended, thereby can in the opening that is connected member 4, be pressed into tapered cup nut 1.By being pressed into tapered cup nut respectively being formed at a plurality of openings that are connected member 4, can finish the operation that is pressed into of tapered cup nut.
Use as described above and squeeze into system automatically, also can easily in being connected the opening of member, squeeze into a plurality of tapered cup nuts.
Next, according to Fig. 9 the formed drill of the 2nd example is described, the conic-insertion-piece that this formed drill is used to form the band female thread of an embodiment of the present invention is the hole that tapered cup nut is imbedded.
Fig. 9 is the hole processing spec figure of the formed drill of used the 2nd example of an embodiment of the present invention.
When using formed drill forming tool illustrated in fig. 3, cutting increases, so can produce vibration at the low drilling machine of lateral stiffness.In order to prevent this problem, use as shown in Figure 9 the formed drill 2 of structure '.
Shown in Fig. 9 (A), use common drill bit 205, leave the pilot hole 303 of screw being connected member 4.
Next, shown in Fig. 9 (B), use formed drill 2 ' processing embedding hole like that, this formed drill 2 ' the have guide portion 206 of external diameter than the little 0.05mm～0.15mm in aperture of pilot hole 303.Formed drill 2 ' except that guide portion 206, the same with formed drill shown in Figure 3, one has tapered portion processing sword 201 and stepped part processing sword 202, this tapered portion processing sword 201 is used to form the hole of the tapered portion 101 of inserting tapered cup nut 1, and this stepped part processing sword 202 is used to form the hole of the lip part 102 that inserts tapered cup nut 1.In addition, formed drill 2 ' the have bore ends sword 204 of deburring, this bore ends sword 204 of deburring is used to remove the burr of the hole terminal part after the perforation.The deburr length and the position of sword 204 of bore ends need be regulated corresponding to the thickness of slab size of joint.
Use the hole shape of this formed drill 2 ' formation identical with situation illustrated in fig. 4.
Illustrate that according to Figure 10 the tapered cup nut that uses an embodiment of the present invention is to 2 operations that are connected the 2nd example that member is threaded below.
Figure 10 is connected the process chart of the 2nd example of the structure that is threaded of member for 2 of the tapered cup nut that uses an embodiment of the present invention.
In joint construction shown in Figure 5, the 2nd connector element is connected a tapered portion opening side opposite side porose with.Yet, in this example, the 2nd connector element is connected the tapered portion opening side.
As explanation among Fig. 5 (A), be processed to form the hole that is used to insert tapered cup nut at the member 4 usefulness formed drills 2 that are connected of aluminum alloy system.Shown in Figure 10 (A), form hole 3 like that by hole processing being connected member 4.Hole 3 by hole tapered portion 301, hole stepped part 302, female thread pilot hole portion 303, and hole terminal chamfered section 304 constitute.In hole 3, insert the tapered cup nut 1 of stainless steel.Tapered cup nut 1 as Fig. 1 or illustrated in fig. 2, constitute tapered portion 101, lip part 102 and female thread 104.
The thickness of the lip part 102 of the depth ratio tapered cup nut 1 of the hole stepped part 302 in hole 3 is shallow.
The tapered portion 101 of tapered cup nut 1 is slight interference fit size for the hole tapered portion 301 in chimeric hole 3.
After tapered cup nut 1 is inserted into hole 3, by by squeeze into beat the lip part 102 hit tapered cup nut 1 above, shown in Figure 10 (B), like that tapered cup nut 1 is driven in the hole 3 that is connected member 4, make lip part 102 contact hole stepped part 302 and stop.In addition, at this moment, the lip part 102 of tapered cup nut 1 makes the upper face side of tapered cup nut 1 protrude from the surface of the 1st connector element 4.
Because the hole tapered portion 301 in hole 3 engages with the tapered portion 101 of tapered cup nut 1, so the axle center in hole 3 is consistent with the axle center of tapered cup nut 1.Therefore, by being connected the Surface Vertical landform pore-forming 3 of member 4, make the axle center and the Surface Vertical that is connected member 4 of tapered cup nut 1.Consistent with the axle center of the tapered portion of tapered cup nut 1 by the axle center that makes the female thread 104 that is formed in the tapered cup nut 1, the central shaft that can easily make female thread 104 is perpendicular to the surface that is connected member 4.
In addition, lip part 102 is set by top at tapered cup nut 1, make tapered cup nut 1 lip part 102 following 103 contact holes 3 hole stepped part 302 and stop.In the occasion that does not have lip part 102, tapered cup nut 1 slips in the hole 3, aluminum alloy system to be connected member 4 softer than stainless steel tapered cup nut 1, so the hole 3 that is connected member 4 significantly is out of shape.Different therewith, by as this form of implementation, lip part 102 being set, can prevent slipping into of tapered cup nut 1 at tapered cup nut 1, prevent the distortion in hole 3.
Under state shown in Figure 10 (B), tapered cup nut 1 is remained in by frictional force and is connected member 4.
Next, have the 2nd of hole 501 when being connected member 5, be connected member 5 in the surface configuration the 2nd of the 1st connector element 4 of squeezing into tapered cup nut 1 when shown in Figure 10 (C), connecting like that, fastening with screw 6.Be connected member 4 the 1st and be the occasion of aluminum alloy system, for example, the 2nd is connected member for the printed circuit board (PCB) of component is installed.Thus, apply load along the tapered portion fixed-direction, so do not have tapered cup nut 1 fully from being connected the worry that member 4 becomes flexible at tapered cup nut 1.
According to this routine method, have under squeezing into the tapered cup nut state with frictional force with nut remain in power in the hole suitable intensity (M4 also is the intensity of number 10Kg).In order to increase join strength in the method, increase connection and count more effective.Particularly be connected member 5 and float the amount that tapered cup nut 1 protrudes from the surface that is connected member 4, so in the occasion that 1 connection is only arranged, floatation volume is easy in tapered cup nut effect sled power, thereby may throw off simply.In order to prevent this problem, it is a plurality of making the nut number, is more than 3 if possible, so that the plane is determined and be stable.
In addition, making value of interference fit, bigger also very important.In example shown in Figure 5, be 2～20% of tapered portion diameter, but under this situation, preferably increase lower limit, be 4～20%.
In the method, as make the stepped part 302 in hole 3 darker, when tightening screw 6, may throw off by the power of screw thread, so bad than the thickness of lip part 102.Screw pilot hole 303 shown in Figure 10 is not necessarily necessary, but is opening also irrespective occasion, have can according to former state use the formed drill 2,2 of Fig. 3, Fig. 9 explanation ' advantage.
As described above, by using the tapered cup nut of this form of implementation, can improve operation.
In addition, can easily prevent the female thread axle offset that forms at tapered cup nut.
In addition, can make the retention force of hole and tapered cup nut certain.
In addition, by carry out hole processing by formed drill, can easily manage value of interference fit.
In addition, can prevent the distortion in hole.
Also can make the mounting or dismounting of tapered cup nut easy, the replacing of tapered cup nut is carried out easily, and can discard respectively material different be connected member and tapered cup nut.
In addition, the recycling tapered cup nut of pulling down.
In addition, also applicable to small screw thread.
In addition, squeezing into hammer of the application of the invention form of implementation can prevent to be connected the damage of member, and make and squeeze into simple to operateization.
In addition, by using the system that squeezes into automatically of this form of implementation, can make also automation easily of drive operation.
