Specific embodiment
The specific embodiment of the present invention is described in detail in conjunction with accompanying drawing.
As shown in Figure 3，The tubular workpiece General piercing fixture of the present invention，Including pedestal 1、Bearing pin 2、Open washer 4、Nut 5 and drill bushing 3，Bearing pin 2 is fixed on pedestal 1，Bearing pin 2 is mainly made up of three parts，Including the root 21 positioned at the left side of 3 corresponding bearing pin 2 of drill bushing、3 corresponding bearing pin 2 of drill bushing and its pars intermedia 22 on right side、And for being inserted in the fastening part 23 of open washer 4 and nut 5，External diameter of the external diameter of root 21 more than pars intermedia 22，External diameter of the external diameter of pars intermedia 22 more than fastening part 23，Boss type support tube 8 is cased with also in pars intermedia 22，The internal diameter of boss type support tube 8 is equal to the external diameter of pars intermedia 22，The external diameter of the boss 82 of boss type support tube 8 is equal to the external diameter of root 21，Internal diameter of the external diameter of the substrate 81 of boss type support tube 8 more than tubular workpiece 6.When the internal diameter of tubular workpiece 6 is less and is just equal to the external diameter of bearing pin root 21, the fixture need not be further added by other adnexaes, only need tubular workpiece 6 is inserted in bearing pin root 2 before Drilling operation, then boss type support tube 8 is inserted in again, in the insertion tubular workpiece 6 of boss 82, substrate 81 supports the right-hand member of tubular workpiece 6, then snap in open washer 4, tightening nut 5, the two ends of tubular workpiece 6 support force upwards is given by the boss 82 of bearing pin root 21 and boss type support tube 8, tubular workpiece 6 is shifted downwards in effectively preventing drilling process.
When the internal diameter of tubular workpiece 6 is more than the external diameter of bearing pin root 21, now bearing pin 2 and boss type support tube 8 cannot give tubular workpiece 6 enough support forces, so that tubulose expansion tube 9 is introduced, as shown in Figure 4.Tubulose expansion tube 9 is socketed on the boss of the root of bearing pin and boss type support tube 8 in pairs.The quantity of tubulose expansion tube 9 can be determined according to the internal diameter size of tubular workpiece 6.For example, the consumption of tubulose expansion tube 9 is 1 pair, then the internal diameter of tubulose expansion tube 9 is equal to the external diameter of 2 root 21 of bearing pin, and its external diameter is exactly equal to the internal diameter of tubular workpiece 6.For another example, it includes N to tubulose expansion tube 9, then to the internal diameter of tubulose expansion tube 9 equal to external diameters of the N-1 to tubulose expansion tube 9, N is equal to the internal diameter of tubular workpiece 6 to N to the external diameter of tubulose expansion tube 9, and wherein, N is the natural number more than or equal to 2.
In order to increase the stability between tubulose expansion tube 9 and bearing pin 2 and boss type support tube 8, prevent tubulose expansion tube 9 from relatively rotating relative to bearing pin 2 and boss type support tube 8, the bearing pin root 21 is provided with the card entry slot 24 for concaving, as shown in Figure 5 and Figure 6.Correspondingly, the card entry slot 83 for concaving is also equipped with the outer wall of the boss 82 of boss type support tube 8, as shown in Figure 7 and Figure 8.What the card entry slot 83 on the outer wall of the boss 82 for being provided with the card entry slot 24 with bearing pin root 21 and boss type support tube 8 on the inwall of tubulose expansion tube 9 was engaged snaps in block 92, as shown in Fig. 9,10,11.The card entry slot（24,83）It is preferably disposed on the side away from drill bushing.When using multiple tubulose expansion tubes 9, in order to prevent the mutual rotation between tubulose expansion tube 9, also it is correspondingly provided with the outer wall of tubulose expansion tube 9 and snaps in the card entry slot 93 that block 92 is engaged.
The announcement and teaching of book according to the above description, those skilled in the art in the invention can also carry out appropriate change and modification to above-mentioned embodiment.Therefore, specific embodiment disclosed and described above is the invention is not limited in, some modifications and changes of the present invention should also be as falling in the scope of the claims of the present invention.Although additionally, some specific terms used in this specification, these terms merely for convenience of description, do not constitute any restriction to the present invention.
