Abstract
An auxiliary guiding shaft sleeve for hole machining particularly consists of a base body (1) and a clamp head (2) fixed thereon, wherein the base body (1) has a tubular structure; the clamp head (2) is arranged at one end of the base body (1), and the outer diameter thereof is greater than that of the base body (1); and hole structures (4) which share the same axis, have the same radius and are integrated into a whole are arranged in both the clamp head (2) and the base body (1). The auxiliary guiding shaft sleeve is characterized in that an annular fixed groove (3) is formed at the connected part of the base body (1) and the clamp head (2), and the annular fixed groove (3) is an inner convex groove provided with a smooth surface and formed by sequentially connecting a plurality of curves and straight lines. By adopting the stepped outer structure design and the design of the fixed groove (3) with the rather small outer diameter, the utility model has the outstanding characteristics that the auxiliary guiding shaft sleeve is convenient to clamp, is stable and reliable after being clamped and positioned, and has an outstanding technical effect.
Description
Technical field
The utility model relates to auxiliary mould structural design and the application technology technical field of using in the high-precision borehole process, provides the processing of a kind of hole to use the aid in guide axle sleeve especially.
Background technology
In the prior art, hole processing is generally the perhaps regular hexagon of the identical smooth rounded of shape of cross section with aid in guide axle sleeve outer wall.It is unfavorable for clamping, and reliable inadequately after the clamping and positioning, and technique effect is not good.Therefore, people expect to obtain the processing of the better hole of a kind of technique effect and use the aid in guide axle sleeve.
Summary of the invention
The purpose of the utility model provides the better hole processing of a kind of technique effect and uses the aid in guide axle sleeve.
The utility model provides the processing of a kind of hole to use the aid in guide axle sleeve, and it specifically is made up of matrix 1 and clamping head 2 fixed thereon, 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; Clamping head 2 is the identical pore structure in aggregates 4 of coaxial line and radius with matrix 1 inside; It is characterized in that: the matrix 1 at an end that belongs to away from clamping head 2 also is provided with holddown groove 3 with clamping head 2 junctions; Holddown groove 3 is an endless groove; It is specially the inner groovy of the surface smoothing that is connected with linear sequence by the multistage curve, holddown groove 3 bottom lands near the distance of the end at clamping head 2 places less than the axis size of clamping head 2 3mm at least.
The processing of said hole uses the axial overall length of aid in guide axle sleeve to be 25mm, and the outer surface diameter of matrix 1 part is 18mm, and the cross-sectional diameter of pore structure 4 is 10mm.
The processing of said hole is with in the aid in guide axle sleeve, and the exit, two ends of pore structure 4 is respectively arranged with the taper chamfering, and chamfer angle is 40-65 ° with respect to the scope of axis.
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 hole processing with the aid in guide axle sleeve.
The specific embodiment:
Shown in accompanying drawing 1, the aid in guide axle sleeve is used in the processing of a kind of hole, and it specifically is made up of matrix 1 and clamping head 2 fixed thereon, 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; Clamping head 2 is the identical pore structure in aggregates 4 of coaxial line and radius with matrix 1 inside; Matrix 1 at an end that belongs to away from clamping head 2 also is provided with holddown groove 3 with clamping head 2 junctions; Holddown groove 3 is an endless groove; It is specially the inner groovy of the surface smoothing that is connected with linear sequence by the multistage curve, holddown groove 3 bottom lands near the distance of the end at clamping head 2 places less than the axis size of clamping head 2 3mm at least.
The processing of said hole uses the axial overall length of aid in guide axle sleeve to be 25mm, and the outer surface diameter of matrix 1 part is 18mm, and the cross-sectional diameter of pore structure 4 is 10mm.
The processing of said hole is with in the aid in guide axle sleeve, and the exit, two ends of pore structure 4 is respectively arranged with the taper chamfering, and chamfer angle is 40-65 ° with respect to the scope of axis: specifically be 45 ° or 60 ° in the present embodiment.
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.
