The specific embodiment
As shown in Figures 2 and 3, the soldering cramping apparatus alignment pin that the utility model embodiment provides, comprises alignment pin 4 and key seat 5, is provided with through hole 6 on alignment pin 4, and through hole 6 is unthreaded hole; On key seat 5, have the connecting hole being connected with the through hole 6 of alignment pin 4; Between through hole 6 on alignment pin 4 and connecting hole on key seat 5, by securing member, be connected.The soldering cramping apparatus alignment pin that the utility model embodiment provides, when alignment pin 4 and key seat 5 are fixed, because being arranged on securing member, its screw thread do not have on alignment pin 4, even if the screw thread after repeatedly dismantling on securing member is damaged, because securing member is standard component, now, as long as change securing member, alignment pin 4 just can continue to use and can not scrap, thereby has extended widely the service life of alignment pin 4.
Further, the bottom of alignment pin 4 can have the groove matching with boss on key seat 5, on key seat 5, can have the groove matching with boss on alignment pin 4 bottoms, this can make between alignment pin 4 and key seat 5 coordinate tightr, connect more firmly, also can prevent preferably that rocking appears in alignment pin 4 after securing member is tightened.
The structural representation of the soldering cramping apparatus alignment pin providing for the utility model the first embodiment as shown in Figure 2.The bottom shape of alignment pin 4 is cylindrical, and the nose shape of alignment pin 4 can be taper shape.Because the coned face of alignment pin 4 heads can match with the locating hole of work piece preferably, thereby realized preferably the location to work piece.
Particularly, at the bottom shape of alignment pin 4, be cylindrical, and the nose shape of alignment pin 4 is while being conical, through hole 6 can be positioned at the medium position of alignment pin 4.Certainly, through hole 6 also can be positioned at other positions of alignment pin 4, owing to now having certain distance between the center of circle of through hole 6 and the center of alignment pin 4, thereby more easily causes rocking of alignment pin 4, and then affects the locating effect of alignment pin 4.And through hole 6 is while being positioned at the medium position of alignment pin 4, together with the center superposition of the center of circle of through hole 6 and alignment pin 4, can not cause rocking of alignment pin 4, thereby guarantee preferably the locating effect of alignment pin 4.
The structural representation of the soldering cramping apparatus alignment pin providing for the utility model the second embodiment as shown in Figure 3.Wherein the head of alignment pin 4 is decussate texture, and the bottom shape of alignment pin 4 is cylindrical.The alignment pin 4 that is conical structure with head is compared, and the volume of the alignment pin 4 that head is decussate texture is relatively little, and its cost is lower.Simultaneously the head due to alignment pin 4 is decussate texture, and this makes it possible to arrange a plurality of through holes 6 on alignment pin 4, to improve preferably the fastness being connected between alignment pin 4 and key seat 5.
Further, when the head of alignment pin 4 is decussate texture, and the bottom shape of alignment pin 4 is while being cylindrical, can have a plurality of through holes 6 on alignment pin 4, and a plurality of through holes 6 are positioned at the surrounding of decussate texture.As shown in Figure 3, the number of through hole 6 can be four, and is evenly distributed in the surrounding of decussate texture, and alignment pin 4 can be connected with key seat 5 preferably by four through holes 6.
It should be noted that, when through hole 6 is circular hole, the diameter of the head of securing member can be greater than the diameter of through hole 6.Now securing member can be directly through the through hole 6 on alignment pin 4 and the connecting hole on key seat 5, alignment pin 4 and key seat 5 are linked together, but securing member now will be longer, thereby cause its cost higher, and because the head of securing member is in the outside of alignment pin 4, the aesthetic property that has affected alignment pin 4 is also easy to work piece to cause damage simultaneously.For fear of occurring the problems referred to above, when through hole is circular hole, the diameter of the head of securing member also can be slightly less than the diameter of through hole 6 on alignment pin 4, the head of securing member can be sunk in the through hole 6 of alignment pin 4, thereby due to the relatively short manufacturing cost that reduces preferably securing member of securing member now, again because the head of securing member is in the through hole 6 of alignment pin 4, thereby the aesthetic property that has improved preferably alignment pin 4 can not cause damage to work piece simultaneously yet.
Further, when through hole 6 is circular hole, and when the diameter of the head of securing member is slightly less than the diameter of through hole 6 on alignment pin 4, through hole 6 can be ladder circular hole, and the diameter of the one end being connected with connecting hole on through hole 6 is less than the diameter of through hole 6 other ends, this head that makes securing member is sinking to through hole 6 when interior, matches in one end that can be less with diameter on through hole 6, thus can make between alignment pin 4 and key seat 5 be connected more firm.
Further, when through hole 6 is circular hole, and when the diameter of the head of securing member is slightly less than the diameter of through hole 6 on alignment pin 4, connecting hole can be ladder circular hole, and the diameter of the one end being connected with through hole 6 on connecting hole is greater than the diameter of the connecting hole other end, the one end being connected with through hole 6 on connecting hole can be provided with packing ring 8, as shown in Figure 4.Because packing ring 8 can play cushioning effect preferably between the head of securing member and the connecting hole of key seat 5, prevent that securing member inner surface to connecting hole when tightening from causing damage, also can increase the friction between securing member and key seat 5, prevent the loosening of connection simultaneously.
Particularly, securing member can be screw, now in the connecting hole on key seat 5, just need to process screw thread, thereby increase processing cost.Owing to there is no screw thread on alignment pin 4, after repeatedly dismantling, even if the screw thread on screw is damaged, because screw is standard component, now needs only the screw more renewing, thereby extended preferably the service life of alignment pin 4.
When securing member is screw, after dismounting repeatedly, can make on key seat 5 screw thread in connecting hole damaged, now just need to change key seat 5, its cost is higher, and causes the service life of key seat 5 shorter.For further extending the service life of alignment pin 4 and key seat 5, securing member can be elected bolt 7 as, as shown in Figure 4.Owing to all there is no screw thread on alignment pin 4 and key seat 5, after repeatedly dismantling, even if the screw thread on bolt 7 is damaged, because bolt 7 is standard components, now need only replacing bolt 7, thereby extended preferably the service life of alignment pin 4, also effectively extended the service life of key seat 5 simultaneously.
The above is only preferred embodiment of the present utility model, it is to be noted, these embodiment are only not used in restriction scope of the present utility model for the utility model is described, and, after having read content of the present utility model, relevant technical staff in the field can make various changes or modification to the utility model, and these equivalent form of values fall into the application's appended claims limited range equally.
