Abstract
The utility model discloses a deep hole drilling positioning sleeve. The deep hole drilling positioning sleeve comprises a positioning sleeve body. A drill bit hole is axially formed in the positioning sleeve body, and a positioning slope is arranged at one end of the positioning sleeve body. Due to the adoption of the structure, when the deep hole drilling positioning sleeve is used, the deep hole drilling positioning sleeve is arranged on a drill bit in a sleeved mode, the positioning slope is supported by a slope to be drilled, and therefore the drill bit is prevented from sliding on a drilling face, and working efficiency and the operation safety factor are improved.
Description
Technical field
The utility model belongs to depth drill technical field, specifically, relates to a kind of depth drill positioning sleeve.
Background technology
Current, because we are when depth drill is holed, most of bore surfaces are not horizontal positioned, there is certain inclination angle, and exactly because this inclination angle causes occurring skidding in boring procedure even boring hindering other parts, more serious caused operator's is injured etc., greatly reduces operating efficiency and handling safety coefficient.
Utility model content
For solving above technical problem, the purpose of this utility model is to provide a kind of depth drill positioning sleeve of good positioning effect.
The utility model object is achieved in that a kind of depth drill positioning sleeve, comprises positioning sleeve body, and its main points are: described positioning sleeve body shaft is to being provided with drill bit bore, and one end of this positioning sleeve body arranges inclined-plane, location; Top on inclined-plane, described location is provided with supporting surface; Described positioning sleeve body is up big and down small step axle sleeve, and this positioning sleeve body bigger diameter end arranges inclined-plane, described location.Adopt above structure, during use, the utility model is enclosed within on drill bit, inclined-plane, location is supported on the inclined-plane that needs boring, thereby has avoided drill bit skidding on bore surfaces, improved operating efficiency and handling safety coefficient.This supporting surface can be against on the inclined-plane that needs boring, thereby better limits the slip of positioning sleeve body, realizes reliably drilling on inclined surface.As preferably: adopt above structure, can position drill bit preferably, locate more reliable.
As preferably: for drill bit in use can be good at stretching out drill bit bore, the diameter of described drill bit bore is greater than the diameter of drill bit.
As preferably: be provided with gap between described supporting surface and drill bit bore, thereby leave large space, good positioning effect can to inclined-plane, location.
As preferably: the angle of inclined-plane, described location and horizontal plane is 15～75 °, the various boring of adaptation inclined-plane that so can be in a big way.
Beneficial effect: the utility model is simple in structure, anti-skidding, can adapt on a large scale the boring on various borings inclined-plane, the safety coefficient of greatly increasing work efficiency and operating.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1: a kind of depth drill positioning sleeve, comprise positioning sleeve body 1, described positioning sleeve body 1 is axially provided with drill bit bore a, one end of this positioning sleeve body 1 arranges inclined-plane 2, location, top on inclined-plane, described location 2 is provided with supporting surface 3, and inclined-plane, described location 2 is 15～75 ° with the angle of horizontal plane.
In Fig. 1, it can also be seen that: described positioning sleeve body 1 is up big and down small step axle sleeve, and this positioning sleeve body 1 bigger diameter end arranges inclined-plane, described location 2, and the diameter of described drill bit bore a is greater than the diameter of drill bit, between described supporting surface 3 and drill bit bore a, is provided with gap.
The above embodiment is only preferred embodiment of the present utility model; not take the utility model as restriction; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
