Abstract
The utility model discloses a drill jig sleeve for drilling a hole. The drill jig sleeve is characterized by specifically consisting of a base body (1) and a clamping head (2), wherein the base body (1) has a tubular structure; the clamping head (2) is arranged at one end of the base body (1); the internal diameter of the clamping head (2) is the same as that of the base body (1); and the external diameter of the clamping head (2) is the same as that of the base body (1). Compared with the prior art, through the design of a stepped external structure and the design of three fixing grooves with relatively small external diameter, the drill jig sleeve has the prominent characteristics of convenience for clamping, stability and reliability after clamping and positioning and superior technical effect.
Description
Technical field
The utility model relates to auxiliary mould structural design and the application technology technical field of using in the construction(al)steel member high-precision borehole process, and a kind of boring drill jig cover is provided especially.
Background technology
In the prior art, boring drill jig cover outer wall is generally the perhaps regular hexagon of the identical smooth rounded of shape of cross section.It is unfavorable for clamping, and reliable inadequately after the clamping and positioning, and technique effect is limited.
Therefore, people expect to obtain the better boring drill jig cover of a kind of technique effect.
Summary of the invention
The purpose of the utility model provides the better boring drill jig cover of a kind of technique effect.
The utility model provides a kind of boring drill jig cover, it is characterized in that: it specifically is made up of matrix 1 and clamping head 2, and wherein: matrix 1 is a tubular structure; Clamping head 2 is arranged on an end of matrix 1, and its internal diameter is identical with matrix 1 internal diameter, and clamping head 2 external diameters are greater than matrix 1 external diameter.
The said boring drill jig cover of the utility model, further preferred the requirement is: the external diameter that also is provided with in matrix 1 and clamping head 2 junctions is less than the holddown groove 3 of matrix 1 external diameter, and the axial width of holddown groove 3 is 2 ± 0.1mm.
It is 20mm that said boring drill jig overlaps axial total length, and the external diameter of matrix 1 part is 15mm, and the internal diameter of matrix 1 part is 5mm.
In terms of existing technologies, the utility model uses the external structure design and less relatively holddown groove 3 designs of external diameter of ladder property, and it has convenient mounting and clamping, and reliable and stable after the clamping and positioning, the outstanding feature that technique effect is good.
Description of drawings:
Fig. 1 is the structural representation front view of boring drill jig cover;
Fig. 2 is the partial enlarged drawing of Fig. 1, is specially the inner enlarged drawing of border circular areas (that is holddown groove 3 places) in the upper right corner among Fig. 1.
The specific embodiment:
A kind of boring drill jig cover (like accompanying drawing 1, shown in 2): it specifically is made up of matrix 1 and clamping head 2, and wherein: matrix 1 is a tubular structure; Clamping head 2 is arranged on an end of matrix 1, and its internal diameter is identical with matrix 1 internal diameter, and clamping head 2 external diameters are greater than matrix 1 external diameter.
In the said boring drill jig cover, the external diameter that also is provided with in matrix 1 and clamping head 2 junctions is less than the holddown groove 3 of matrix 1 external diameter, and the axial width of holddown groove 3 is 2 ± 0.1mm.
It is 20mm that said boring drill jig overlaps axial total length, and the external diameter of matrix 1 part is 15mm, and the internal diameter of matrix 1 part is 5mm.
In terms of existing technologies, present embodiment uses the external structure design and less relatively holddown groove 3 designs of external diameter of ladder property, and it has convenient mounting and clamping, and reliable and stable after the clamping and positioning, the outstanding feature that technique effect is good.
