Abstract
The invention discloses a vertical hole-enlarging positioning guided tooling. A tooling body consists of a cylinder (1) with a large end and a cylinder (2) with a small end, wherein the diameter of the cylinder (1) with the large end is more than the diameter of a circular hole (3) to be enlarged, the cylinder (2) with the small end can be in clearance fit with the circular hole (3) to be enlarged, an large end surface side of the body is provided with a conical blind hole (4) along a central axis, and the conical degree thereof is 118 degrees. In the vertical hole-enlarging positioning guided tooling of the invention, when the circular hole to be enlarged is processed by a drill, the tooling can be firstly assembled in the circular hole to be enlarged, then the drill is enabled to align the conical blind hole on the top part of the tooling, the drill can quickly and accurately find the circular hole to be enlarged by conical degree of the tooling which is the same as that of the drill, and thereby the processing efficiency and processing accuracy of the circular hole to be enlarged can be improved.
Description
Technical field
The present invention relates to the hole processing tool in a kind of machining, particularly relate to a kind of hole-enlarging positioning guided tooling.
Background technology
In machining, all need to hole first for the processing of the slightly high hole of required precision and carry out again reaming and process, particularly the hole for large-scale porous plate processes, carrying out reaming such as the heat exchanger tube installing hole on the tube sheet of heat exchanger processes, hundreds and thousands of of the heat exchanger tube installing hole of a tube sheet, processing capacity is very large, and at this moment the simplest mode of reaming is to adopt common drill bit to carry out reaming, adopts drill bit to carry out vertical hole-enlarging and not only makes things convenient for but also economical.During reaming, the location centering of drill bit is particularly crucial, directly affects the crudy of institute's reaming, but this operation generally relies on naked eyes to feel by rule of thumb to carry out the tool setting location at present, and not only efficient is lower and the reaming difficult quality guarantee, even injures easily drill bit and workpiece.
Summary of the invention
Technical problem to be solved by this invention provides a kind of drill bit head centering that can make rapidly and accurately and treats the vertical hole-enlarging positioning guided tooling at reaming center.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of vertical hole-enlarging positioning guided tooling, main body is made of coaxial large end cylinder and small end cylinder, wherein the diameter of large end cylinder is greater than the diameter of circular hole to be expanded, the small end cylinder can form matched in clearance with circular hole to be expanded, the large end face side of described main body offers conical blind hole along central axis, and its tapering is 118 degree.
As preferably, the material of described frock main body is the 20Cr steel alloy, and there is carburized layer on the surface.
As preferably, the end face of described small end cylinder is provided with chamfering.
A kind of vertical hole-enlarging positioning guided tooling of the present invention, carry out reaming and add man-hour adopting drill bit to treat reaming, can first this frock be assemblied in and treat in the reaming, again with the conical blind hole at drill bit frock top, rely on its tapering identical with angle of drill bit that drill bit is found rapidly and accurately and treat the reaming center, thereby improve efficient and the machining accuracy of reaming processing.
A kind of vertical hole-enlarging positioning guided tooling of the present invention, the frock material of main part adopts the 20Cr steel alloy and carries out Carburization Treatment, and its hardness and wearability are all better, are conducive to improve its service life; At the end face of small end cylinder chamfering being set can make things convenient for frock and with the assembling between the processing work, increase work efficiency.
In sum, a kind of vertical hole-enlarging positioning guided tooling of the present invention, structural design is simple, Effective Raise the working (machining) efficiency and the machining accuracy that adopt drill bit to carry out reaming, practical.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is the work schematic diagram of a kind of vertical hole-enlarging positioning guided tooling of the present invention.
Fig. 2 is the structural representation of a kind of vertical hole-enlarging positioning guided tooling of the present invention.
Wherein, Reference numeral: 1 is large end cylinder, and 2 is the small end cylinder, and 3 is conical blind hole, and 4 are circular hole to be expanded, and 5 is small end cylindrical end surface chamfer.
The specific embodiment
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
As depicted in figs. 1 and 2, a kind of vertical hole-enlarging positioning guided tooling of the present invention, main body is made of coaxial large end cylinder 1 and small end cylinder 2, wherein the diameter of large end cylinder 1 is greater than the diameter of circular hole 4 to be expanded, small end cylinder 2 can form matched in clearance with circular hole 4 to be expanded, the large end face side of described main body offers conical blind hole 3 along central axis, and its tapering is 118 degree.The concentricity tolerance of large end cylinder 1 and small end cylinder 2 is Ф 0.03.Small end cylinder 2 needs to form matched in clearance with circular hole 4 to be expanded, and so not only has been convenient to assemble but also can play the effect of more accurate positioning and guiding.The taper design of conical blind hole 3 is that 118 degree are for the angle with drill bit is consistent, thereby plays the effect of guide-localization centering.
As depicted in figs. 1 and 2, a kind of vertical hole-enlarging positioning guided tooling of the present invention, the material of frock main body is the 20Cr steel alloy, and there is carburized layer on the surface, and this frock just has good hardness and wearability like this.The end face of frock small end cylinder 2 is provided with chamfering 5.
As shown in Figure 1, a kind of vertical hole-enlarging positioning guided tooling of the present invention, add man-hour adopting drill bit to treat to expand circular hole 4 to carry out reaming, can this frock be assemblied in the circular hole 4 to be expanded first, even small end cylinder 2 is arranged in circular hole 4 to be expanded, again with the conical blind hole 3 at drill bit frock top, rely on its tapering identical with angle of drill bit to make drill bit and conical blind hole 3 centers to it, thereby find rapidly and accurately center of circular hole to be expanded, determine the optimum position of drill bit.
