Abstract
The utility model discloses a drill jig for punching flanges. The drill jig comprises a cylindrical drill plate; a hollow cylindrical boss is arranged on the front surface of the cylindrical drill plate; threads are formed in a hollow part of the cylindrical boss; a blind hole is formed in the center of the reverse surface of the cylindrical drill plate; at least one guiding hole is also formed in the front surface of the cylindrical drill plate; and the drill jig for punching flanges can be used for punching at least two kinds of flanges by the cylindrical boss arranged on the front surface of the cylindrical drill plate and the blind hole in the center of the reverse surface of the cylindrical drill plate. Compared with the conventional drill jig which can only be used for punching one kind of flanges, the drill jig has the advantages that the occupied space of the drill jig is saved to a certain degree, and resources are saved.
Description
Technical field
The utility model relates to the tool field of machining, is specifically related to a kind of drill jig that is used for the flange punching.
Background technology
The method of on flange, punching now has three kinds, and first method is manual in the flange surface setting-out, and with the drilling machine punching, this method is higher to workman's specification requirement, and efficient is very low then; Second method is to punch on flange with Digit Control Machine Tool, but the Digit Control Machine Tool one-time investment is very big, and a lot of medium-sized and small enterprises do not have enough funds to buy these advanced equipment, and Digit Control Machine Tool can not satisfy the punching demand of big part flange; The third method is made corresponding drill jig and is come auxiliary flange boring according to the difference of flange shape specification, and with the drilling machine punching, this method is easy to use then, and one-time investment is moderate, is widely used in medium-sized and small enterprises.But the employed drill jig of this method, owing on the flange positioning step is arranged, even the flange that pairing is used, a drill jig also can only be applied to a kind of flange specification, has caused the wasting of resources to a certain extent.
The utility model content
For solving the problems of the technologies described above; We have proposed a kind of drill jig that is used for the flange punching; Through the blind hole that the boss that is provided with in said cylindric bushing plate front and said cylindric bushing plate reverse side are provided with, make a drill jig that is used for the flange punching can satisfy the punching demand of at least two kinds of flanges simultaneously.Compare the punching demand that an existing drill jig can only satisfy a kind of flange, saved resource.
For achieving the above object, the technical scheme of the utility model is following:
A kind of drill jig that is used for the flange punching comprises cylindric bushing plate; Said cylindric bushing plate front is provided with the cylindrical boss of hollow; The vacancy is provided with screw thread in said; Said cylindric bushing plate reverse side center is provided with a blind hole; Said cylindric bushing plate front also is provided with at least one pilot hole.
Preferably, the middle vacancy of said cylindric bushing plate, said cylindrical boss and said blind hole are on the same central axis.
Preferably, said cylindrical boss external diameter and said blind hole internal diameter are consistent.
Pass through technique scheme; The blind hole that the utility model is provided with through the cylindrical boss that is provided with in cylindric bushing plate front and reverse side center; Make a drill jig that is used for flange punching can satisfy the punching demand of at least two kinds of flanges simultaneously, especially the punching demand of pairing use flange is compared the punching demand that an existing drill jig can only satisfy a kind of flange; Save the occupation of land space of drill jig to a certain extent, avoided the wasting of resources.

The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of drill jig that is used for the flange punching; Its operation principle is: as depicted in figs. 1 and 2; Through be provided with the cylindrical boss 11 of hollow in cylindric bushing plate 1 front; Be provided with blind hole 12 at cylindric bushing plate 1 reverse side, make a drill jig that is used for flange punching can satisfy the punching demand of at least two kinds of flanges simultaneously.Compare the punching demand that an existing drill jig can only satisfy a kind of flange, practiced thrift resource to a certain extent.
Below in conjunction with the embodiment and the specific embodiment the utility model is done further detailed explanation.
Embodiment.
As depicted in figs. 1 and 2, a kind of drill jig that is used for the flange punching comprises cylindric bushing plate 1, and cylindric bushing plate 1 front is provided with the cylindrical boss 11 of hollow, and the vacancy is provided with screw thread in the cylindrical boss 11; Cylindric bushing plate 1 reverse side center is provided with a blind hole 12; Cylindric bushing plate 1 front also is provided with 16 pilot holes 13; Cylindric bushing plate 1, cylindrical boss 11, through hole and blind hole 12 central shafts overlap, and cylindrical boss 11 external diameters and blind hole 12 internal diameters are consistent.
As shown in Figure 3 is first workpiece 2; Shown in Figure 4 is that second workpiece, 3, the first workpiece 2 and second workpiece 3 are flange assemblies that pairing is used, when first workpiece 2 and second workpiece 3 are installed; Like Fig. 3 and shown in Figure 4, the groove 31 of boss 21 corresponding second workpiece 3 of first workpiece 2.When processing the hole on first workpiece 2, matching the blind hole 12 of cylindric bushing plate 1 reverse side with the boss 21 of first workpiece 2 compresses, and just can utilize 13 pairs first workpiece 2 of pilot hole to punch.When processing the hole on second workpiece 3, matching cylindric bushing plate 1 positive cylindrical boss 11 with the groove 31 of second workpiece 3 compresses, and at this moment just can utilize 13 pairs second workpiece 3 of pilot hole to punch.
Therefore; The described a kind of drill jig that is used for the flange punching of the utility model; The blind hole 12 that cylindrical boss 11 and the reverse side that is provided with through cylindric bushing plate 1 front is provided with makes a drill jig that is used for the flange punching can satisfy the punching demand of at least two kinds of flanges simultaneously.Compare the punching demand that an existing drill jig can only satisfy a kind of flange, avoided the waste of resource to a certain extent.
To disclosed a kind of above-mentioned explanation that is used for the drill jig embodiment of flange punching, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
