Abstract
The utility model discloses a drill inclined hole aligning tool. A through hole is arranged on the lower end of a Mohs taper shank measuring rod (1). A right-angle type measuring needle (6) penetratesthrough the through hole and radially moves left and right along the Mohs taper shank measuring rod (1). A first locking screw (5) correspondingly locked with the right-angle type measuring needle (6) is arranged on the Mohs taper shank measuring rod (1). A long through hole is arranged on the Mohs taper shank measuring rod (1) in the axial direction. A positioning sleeve (3) corresponding to thelong through hole is slidably sheathed on the Mohs taper shank measuring rod (1). A right-angle type marking awl (4) penetrates through the positioning sleeve (3) and the long through hole to be correspondent to the right-angle type measuring needle (6). A second locking screw (2) correspondingly locked with the right-angle type marking awl (4) is arranged on the positioning sleeve (3). The innerright-angle long edge (11) of the right-angle type marking awl (4) is equal to the inner right-angle short edge (12) of the right-angle type measuring needle (6). The drill inclined hole aligning tool has convenient application and simple structure, can completely eliminate the influence of the inclined plane workbench angle error to the inclined hole position and accurately find the inclined hole position.
Description
Technical field
The utility model relates to a kind of pincers worker line centering instrument, particularly relates to a kind of rat holing centering instrument.
Background technology
Need the part of rat holing more, the lower extreme point position dimension of inclined hole is a significant dimensions, and the effect of inclined hole is mainly used in supercooling liquid and lubricating fluid, if this lower extreme point position, hole is subjected to displacement, cooling fluid just can't be passed through, and very easily causes other part Yin Wendu too high and burn out.Existing rat holing frock and manufacturing process, file often need be done over again, be repaiied to the very difficult status requirement that guarantees the inclined hole lower extreme point.
The utility model content
Technical problem to be solved in the utility model provides a kind of easy to use, simple in structure and can get rid of the influence of inclined-plane workbench angular error to the inclined hole position fully, accurately finds the rat holing centering instrument of inclined hole position accurately.
In order to solve the problems of the technologies described above, the rat holing centering instrument that the utility model provides, Morse taper shank measuring stick lower end is provided with a through hole, the perpendicular type surveyingpin passes described through hole and can be along described Morse taper shank measuring stick move left and right radially, on described Morse taper shank measuring stick, be provided with first lock-screw of corresponding locking with described perpendicular type surveyingpin, on described Morse taper shank measuring stick, be axially arranged with long through-hole, slip cap is equipped with the positioning sleeve corresponding with described long through-hole on described Morse taper shank measuring stick, the square scriber passes described positioning sleeve and described long through-hole is corresponding with described perpendicular type surveyingpin, be provided with second lock-screw of corresponding locking with described square scriber on described positioning sleeve, long limit, the interior right angle of described perpendicular type scriber equates with right angle minor face in the described perpendicular type surveyingpin.
The cross section of described perpendicular type surveyingpin and described square scriber is a rectangle, and described through hole is a rectangular opening, and described long through-hole is the rectangle long through-hole.
Adopt the rat holing centering instrument of technique scheme, utilize the projection theory of point, inclined hole lower extreme point position is reflected to the processing plane of inclined hole.The cross section of perpendicular type surveyingpin and square scriber is a rectangle, through hole is a rectangular opening, and long through-hole is the rectangle long through-hole, and perpendicular type surveyingpin and square scriber cooperate with rectangular opening and rectangle long through-hole, perpendicular type surveyingpin and square scriber just can not rotate, thereby have guaranteed the precision of centering.The utility model is a kind of easy to use, simple in structure and can get rid of the influence of inclined-plane workbench angular error to the inclined hole position fully, accurately finds the rat holing centering instrument of inclined hole position accurately.

Fig. 3 is to use the process schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, Morse taper shank measuring stick 1 lower end is provided with a square type hole 10, perpendicular type surveyingpin 6 passes rectangular opening 10 and can be along Morse taper shank measuring stick 1 move left and right radially, on Morse taper shank measuring stick 1, be provided with first lock-screw 5 with the 6 corresponding lockings of perpendicular type surveyingpin, on Morse taper shank measuring stick 1, be axially arranged with rectangle long through-hole 9, slip cap is equipped with the positioning sleeve 3 corresponding with rectangle long through-hole 9 on Morse taper shank measuring stick 1, square scriber 4 passes positioning sleeve 3 and rectangle long through-hole 9 is corresponding with perpendicular type surveyingpin 6, on positioning sleeve 3, be provided with second lock-screw 2 with the 4 corresponding lockings of square scriber, long limit 11, the interior right angle of perpendicular type scriber 4 equates that with perpendicular type surveyingpin 6 interior right angle minor faces 12 cross section of perpendicular type surveyingpin 6 and square scriber 4 is a rectangle.
Referring to Fig. 3:
1, Morse taper shank measuring stick 1 is contained on the radial drilling machine main shaft 8;
2, move up and down after drill press spindle 8 makes the summit alignment pieces 7 inclined holes 13 lower end position lines of perpendicular type surveyingpin 6, locking drill press spindle 8 is also tightened first lock-screw 5 and is made perpendicular type surveyingpin 6 fixing.
3, move up and down and tighten second lock-screw 2 after positioning sleeve 3 makes the summit of perpendicular type scriber 4 touch the processing plane of inclined hole 13, move left and right perpendicular type scriber 4 end face that makes long limit, perpendicular type scriber 4 right angles and long limit, perpendicular type surveyingpin 6 right angles inner plane are by putting down again.
The contact point of the processing plane of the summit of perpendicular type scriber 4 and inclined hole 13 is the location point of inclined hole 13 at this moment.
