Description
Technical field
The utility model relates to glass processing instrument, is specifically related to glass drilling instrument.
Background technology
Carry out in boring procedure to glass, particularly by using hand drill to punch to glass, due to the characteristic of glass itself, hard and crisp, in boring procedure, drill bit easily slides at glass surface and causes the changing of the relative positions of bore position, when particularly processing symmetrical holes, if processing dislocation causes being difficult to assemble, and tradition is holed to glass, have a large amount of cullet to remain, cause cleaning trouble.
Utility model content
The purpose of this utility model is to provide a kind of boring bar tool can being convenient to glass drilling.
In order to solve the problem, the scheme that the utility model proposes is: glass drilling instrument, comprise electric hand drill, hollow thin-wall bores and locating cover, the brill of described electric hand drill is provided with sliding cavity with it, described locating cover is embedded in sliding cavity by spring, the below of locating cover is provided with sucker, described hollow thin-wall brill is arranged on the central shaft of electric hand drill rotation, it is the multiple tooth drilling area in gap that hollow thin-wall bores working position, be fixedly installed a bar shaped drill bit with the pivot of drill bit, the diameter of described locating cover is greater than the double diameter of hollow thin-wall brill.
Glass, in boring procedure, first by locating cover and glass contact, and extrudes locating cover downwards, makes the sucker of locating cover be close on glass, starts the Drilling operation that electric hand drill carries out glass.
Use benefit of the present utility model to be: owing to being embedded in sliding cavity at locating cover by spring, in time holing to glass, the diameter of locating cover is greater than the double diameter of hollow thin-wall brill, and the below of locating cover is provided with sucker; Locating cover is attached on glass to be drilled by sucker firmly, first electric hand drill is carried out circular orientation by locating cover, and hole surrounding is carried out airtight by sucker, after starting electric hand drill, bar shaped drill bit is fixed as center, when boring, can prevent hollow thin-wall from getting out existing sidesway.
Further, in order to prevent glass thicker, there is the phenomenon of the overheated burning of bits in boring procedure, dropper is provided with, in comparatively heavy sheet glass boring procedure, to the logical upper cooling water of dropper in described locating cover, make to cool drill bit in time in boring procedure, effectively can avoid the burning of bits.
Further, discharge for the ease of cooling water, and can not affect the adsorptivity of sucker, described locating cover sidewall is provided with one and irises out water hole, apopore Distance positioning cover lower limb 10cm; To ensure in locating cover that unnecessary water can continue heat to take away lower than the water of apopore as the cooling of drill bit with ensure that chip exists in locating cover.
Finally, lower limb length 0.5 ~ 1mm that the termination that described bar shaped is bored is bored than hollow thin-wall, like this when boring glass, bar shaped is bored after 0.5 ~ 1mm under glass drill, hollow thin-wall brill carries out larger-diameter hole again and processes, center due to hole is first bored by bar shaped and is positioned, then carries out processing to large diameter hole and would not there is skew.
Accompanying drawing explanation
Fig. 1 is glass drilling tool construction schematic diagram of the present utility model;
Fig. 2 is the structural representation of Fig. 1 hollow core thin-walled drill.
Wherein Reference numeral is arranged as: electric hand drill 1; Bar shaped drill bit 2; Spring 3; Hollow thin-wall bores 4; Sucker 5; Apopore 6; Locating cover 7; Dropper 8; Glass 9.
Detailed description of the invention
Here further illustrates technical solutions of the utility model in conjunction with the accompanying drawings and embodiments.
According to Fig. 1 and Fig. 2, glass drilling instrument, comprise electric hand drill 1, hollow thin-wall bores 4 and locating cover 7, the brill of electric hand drill 1 is one-body molded is with it a sliding cavity, locating cover 7 is embedded in sliding cavity, restoring force can be obtained to make locating cover 7, a spring 3 is had in sliding cavity inner sleeve, the below of locating cover 7 is fixedly connected with sucker 5, sucker 5 is C type plantation rubber annular groove, hollow thin-wall bores 4 and is arranged on the central shaft of electric hand drill 1 rotation, it is the multiple tooth drilling area in gap that hollow thin-wall bores 4 working positions, the pivot of hollow thin-wall brill 4 is fixed with a bar shaped drill bit 2, the termination 1mm longer than the lower limb of hollow thin-wall brill 4 of bar shaped drill bit 2, hollow thin-wall brill 4 carries out larger-diameter hole again and processes, center due to hole is first bored 2 by bar shaped and is positioned, 4 can be bored to hollow thin-wall to locate further.
The thicker phenomenon that there will be the overheated burning of bits of boring procedure glass 9, dropper 8 is provided with in locating cover 7, dropper extends to outside locating cover portion, to in comparatively heavy sheet glass 9 boring procedure, to the logical upper cooling water of dropper 8, make to cool drill bit in time in boring procedure, effectively can avoid the burning of bits, locating cover 7 sidewall is provided with one and irises out water hole 6, apopore 6 Distance positioning cover 7 lower limb 10cm; Ensure that unnecessary water flows away from apopore 6 lower than the cooling of the water of apopore 6 as drill bit in locating cover 7, continue heat to take away.By being provided with filter screen, apopore 6 ensures that chip can not be discharged to outside locating cover 7, do not worry that glass 9 chip flows out along with current.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
