Abstract
The invention relates to a small-hole grinding tool of a drilling machine for correcting hole diameter. The small-hole grinding tool comprises a grinding mandrel; the grinding mandrel is a conical shaft, and the large-diameter end thereof is a clamping part; the clamping part is provided with a circular slot in the radial direction, and an open-ended steel wire ring is arranged in the circular slot; and the other side is a working part, and the working part is sleeved with an open-ended grinding sleeve in a matching way. When in use, the small-hole grinding tool is directly arranged on a chuck of the drilling machine; and the diameter of a small hole on the drilling machine which deforms and is out of round after thermal treatment and hardening is corrected under the premise of keeping the position of a traditional work piece hole, and the self-centering and automatic abrasive supply functions can be realized.
Description
Technical field
The present invention relates to the aperture lap of a kind of drilling machine with the correction aperture.
Background technology
At present, for mostly adopting diamond reamer to carry out because of the heat treatment small aperture finishing that back distortion loses circle of hardening on the parts, but because of difference required diamond reamer in aperture need customize and will not only waste fund by many of trim amount size customizations, and operation is very inconvenient.
Summary of the invention
In order to solve, the invention provides a kind of aperture lap that is used to revise the aperture because of the heat treatment small aperture finishing that back distortion loses circle of hardening needs customization many problem of instrument.
Concrete structural design scheme is as follows:
The aperture lap that is used to revise the aperture comprises the grinding mandrel, and described grinding mandrel is a cone axis, and its larger diameter end is a retained part, and retained part radially is provided with an annular groove, is provided with the opening wire loop in the annular groove; Its opposite side is a working portion, and the working portion engage sleeves is provided with the opening grinding sleeve.
The tapering that grinds mandrel working portion tapering and opening grinding sleeve endoporus is 1: 50 or other self-locking taperings.
The annular groove cross section of retained part is semicircle.
The opening grinding sleeve is a thin-wall construction, and its wall thickness is 0.8-1.2mm, and its open slot is for becoming the diagonal cut joint of angle with axis.
Useful technique effect of the present invention is embodied in the following aspects:
1, reasonable in design
The opening wire loop is made of the minor diameter steel wire, can be clamped in the semi-circular groove of tapering mandrel and exceeds the periphery (opening part can not be closed) of tapering mandrel.Can snap in when clamping in the groove of drill chuck hostage part, tapering mandrel periphery and drill chuck clamping part have the little clearance Δ when guaranteeing to clamp, and the tapering mandrel is clamped in the drill chuck can the trace swing but do not have axial float; The working portion cylindrical that grinds mandrel is processed into 1: 50 tapering of standard so that self-locking; The external diameter of opening grinding sleeve is slightly less than and is ground the part aperture, and wall thickness is at 0.8mm to 1.2mm, and length is with isometric by the grinding hole in piece part.Endoporus is processed into 1: 50 tapering with the reamer of minor diameter, and cylindrical is axially opened a diagonal cut joint groove that forms an angle with axis, and the abrasive in the time of can depositing abrasive to grinding in the diagonal cut joint groove carries out in time replenishing, and abrasive is run off when grinding fast.
2, easy to operate
During use, the drill chuck that is directly installed on drilling machine gets final product.
3, on drilling machine, the aperture of circle is lost in harden back distortion of heat treatment, under the prerequisite that keeps former workpiece hole location, repair the aperture, can realize the automatic makeup function of self-centering and abrasive.
Description of drawings
Fig. 1 is a structural representation of the present invention,
Fig. 2 is the user mode partial enlarged drawing.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described by embodiment.
Embodiment:
Referring to Fig. 1, the aperture lap that is used to revise the aperture comprises and grinds mandrel 1, and the grinding mandrel is a cone axis, and its larger diameter end is a retained part, and retained part radially is provided with an annular groove, is installed with opening wire loop 2 in the annular groove; Its opposite side is a working portion, and the working portion engage sleeves is provided with opening grinding sleeve 3.The tapering that grinds mandrel 1 working portion tapering and opening grinding sleeve 3 endoporus is 1: 50 degree, and opening grinding sleeve wall thickness is 0.8-1.2mm, and its open slot is for becoming the diagonal cut joint groove of angle with axis; The annular groove cross section of retained part is semicircle.
During use, there is an end of opening wire loop 2 to pack in the drilling machine drill chuck tapering mandrel, the opening wire loop is packed in the annular groove of drill chuck hostage part during clamping, opening grinding sleeve 3 is contained on the working portion of tapering mandrel, smear abrasive pastes (fluting place multiple spot) on the outer surface, opening grinding sleeve 3 is packed into by in the grinding hole in piece part, the startup drilling machine moves up and down tapering mandrel 1 (manually) repeatedly and tries to grind, and constantly adjust upward the position of opening grinding sleeve 3, when move up and down this lap when slightly feeling resistance explanation grinding.Grind the back resistance through a few minutes and reduce to continue trace upwards and adjust the position of opening grinding sleeve and grind, until being reached requirement by grinding part endoporus.For guaranteeing to be ground the cylindricity of hole in piece part, the opening grinding sleeve end face during grinding on the tapering mandrel moves up and down must surpass the end face that is ground hole in piece part but surpass length at every turn and is not more than 1/3 of opening grinding sleeve length.To constantly replenish abrasive pastes in the process of lapping to opening grinding sleeve surface.To clean lapped face and measure the aperture through kerosene commonly used in the process of lapping.
