Abstract
The utility model discloses a universal type drilling device. The universal type drilling device comprises a drill bit handle and a drill bit portion arranged at the front end of the drill bit handle, wherein the drill bit handle comprises an external drill bit connecting portion and an internal drill bit connecting portion, the drill bit portion comprises an internal small hole drill bit and a hollow external large hole drill body, the external large hole drill bit is connected with the external drill bit connecting portion, the internal small hole drill bit is connected with the internal drill bit connecting portion, the internal small hole drill bit is arranged in the hollow portion of the external large hole drill bit, and the front end of the internal small hole drill bit extends out of the external large hole drill bit. The universal type drilling device is simple in structure and can drill two types of holes with different inner diameters, the internal small hole drill bit and the external large hole drill bit are arranged in a separated mode, and therefore the depths of holes with different hole diameters can be adjusted as required. In comparison with the prior art, the drilling effect and the drilling accuracy can be effectively improved, and practicability is good.
Description
Technical field
The utility model belongs to the boring field, is specifically related to a kind of universal drilling equipment.
Background technology
The drill bit of prior art generally all is single type, that is to say the hole that to bore a diameter, if when in a hole, needing to bore the hole that two kinds of internal diameters differ, need to get out a kind of hole with a kind of boring bar tool first, and then replacing the second boring bar tool gets out the second hole, so not only lose time, but also can reduce working (machining) efficiency, be difficult to satisfy the needs of processing.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, does not need to change the universal drilling equipment of drilling tool when boring two kinds of inner diameter holes.
The technical scheme that realizes the utility model purpose is a kind of universal drilling equipment, comprise the drill head handle, be arranged on the boring head of described drill head handle front end, described drill head handle comprises outside drill head connecting portion and an internal bore connecting portion, described boring head comprises the external macro pores drill bit of inner aperture drill bit and hollow, described external macro pores drill bit is connected with described outside drill head connecting portion, described inner aperture drill bit is connected with a described internal bore connecting portion, described inner aperture drill bit is arranged in the hollow bulb of described external macro pores drill bit, and front end stretches out the setting of external macro pores drill bit.
Between described inner aperture drill bit and a described internal bore connecting portion, be provided with and regulate the length adjustment device that described inner aperture drill bit stretches out the external macro pores the length of the bit.
Between described external macro pores drill bit and inner aperture drill bit, be provided with isolating cylinder.
The utlity model has positive effect: of the present utility model simple in structure, it can get out the hole of two kinds of different inner diameters, and the inner aperture drill bit separated setting with the external macro pores drill bit, can regulate as required the degree of depth of different pore size, compare conventional art, but Effective Raise boring effect and borehole accuracy, practicality is good.
Description of drawings
For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings, wherein:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
(embodiment 1)
Fig. 1 has shown a kind of specific embodiment of the present utility model, and wherein Fig. 1 is structural representation of the present utility model.
See Fig. 1, a kind of universal drilling equipment, comprise drill head handle 1, be arranged on the boring head 2 of described drill head handle 1 front end, described drill head handle 1 comprises outside drill head connecting portion 11 and an internal bore connecting portion 12, described boring head 2 comprises the external macro pores drill bit 22 of inner aperture drill bit 21 and hollow, described external macro pores drill bit 22 is connected with described outside drill head connecting portion 11, described inner aperture drill bit 21 is connected with a described internal bore connecting portion 12, described inner aperture drill bit 21 is arranged in the hollow bulb of described external macro pores drill bit 22, and front end stretches out the setting of external macro pores drill bit.It can get out the hole of two kinds of different inner diameters, and the inner aperture drill bit is separated setting with the external macro pores drill bit, can regulate as required the degree of depth of different pore size, compares conventional art, but Effective Raise boring effect and borehole accuracy, and practicality is good.
Between described inner aperture drill bit 21 and a described internal bore connecting portion 12, be provided with and regulate the length adjustment device 3 that described inner aperture drill bit stretches out the external macro pores the length of the bit.
Between described external macro pores drill bit 22 and inner aperture drill bit 21, be provided with isolating cylinder 23.
Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection domain of the present utility model.
