Abstract
The utility model relates to a scriber dedicated to an NC (numerical control) deep-hole driller, which is characterized in that a scriber body matched with a deep-hole driller guide bushing inner hole is included, a threaded connecting head matched with a deep-hole driller drilling rod is fixedly connected with the tail end of the scriber body, a scriber tip capable of properly sliding in the scriber body is connected with the head part of the scriber body, and a compression spring is mounted between the scriber tip and the connecting head; and the combination clearance between the outer diameter of the scriber body and the inner hole of the deep-hole driller guide bushing inner hole is 0.01 mm. The scriber is used to scribe a cross line at the center of a tube sheet and lead the cross line to have a precision controlled in NC precision range in positions with other holes; and the cross line serves as the reference for the later period process of the tube sheet, so that the processing precision of the whole tube sheet is improved.
Description
Technical field
The utility model relates to a kind of instrument, especially relates to a kind of scriber of processing tube sheet with the NC deep hole drilling machine bed.
Background technology
Large-sized boiler high-pressure heater, low-pressure heater tube sheet, not only thick (350～550mm) and hole (Φ 16.2) One's name is legion (see figure 1), four over thousands of holes are generally arranged.Must on the NC deep hole drilling machine bed, process.On the NC deep hole drilling machine bed, process, need a kind of scriber and can give full play to the numerical control precision of lathe, under clamping of workpiece (tube sheet), use this scriber and mark the central cross line of tube sheet by lathe, the positional precision in it and each hole is reached within the numerical control accuracy rating.Cross hairs will be as the benchmark of tube sheet post-production, thereby improves the machining accuracy of whole tube sheet.
Summary of the invention
Main purpose of the present utility model is: develop and a kind ofly can be applicable to that the numerical control deep-hole that is marked numerous quantity tube sheet central cross lines by lathe bores special-purpose scriber under clamping.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the special-purpose scriber of a kind of NC deep hole drilling machine bed, it is characterized in that: have the scriber body that matches with depth drill guide pin bushing endoporus, the tail end of described scriber body is fixed with the threaded connector that matches with the depth drill drilling rod, the head of described scriber body is connected with the needle point that can suitably slide in the scriber body, the compression spring is installed between described needle point and the connector.
Scriber body diameter and depth drill guide pin bushing endoporus fit clearance are 0.01mm.
Therefore, the beneficial effects of the utility model are: simple in structure, and under clamping, use this scriber and mark the central cross line of tube sheet by lathe, the positional precision in it and each hole is reached within the numerical control accuracy rating.Cross hairs will be as the benchmark of tube sheet post-production, thereby improves the machining accuracy of whole tube sheet.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is tube sheet schematic diagrames.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
As shown in the figure, has the scriber body 2 that matches with depth drill guide pin bushing endoporus, the tail end of scriber body is connected with the threaded connector 4 that matches with the depth drill drilling rod, adopt the bonding way of binding agent to be connected between the tail end of scriber body and the threaded connector, the head of scriber body 2 is connected with the needle point 1 that can suitably slide in the scriber body, compression spring 3 is installed in the scriber body between needle point 1 and the connector 4, needle point 1 can suitably be floated in scriber body 2, it had both guaranteed soft contact the between needle point and tube sheet, can not damage drilling rod, can make needle point that certain thrust is arranged again, the clear wash rice of ruling.Scriber body diameter and depth drill guide pin bushing endoporus fit clearance are 0.01mm.Adopt this scriber to mark the central cross line of tube sheet by lathe, cross hairs will improve the machining accuracy of whole tube sheet as the benchmark of tube sheet post-production.
