Abstract
The utility model belongs to the technical field of machining, and relates to a tool, in particular to a tool row with a movable centering shaft for a radial drilling machine. The tool row comprises a guiding mandrel, a spacer bush and an outer sleeve, the guiding mandrel is installed in an inner hole of the outer sleeve through bearings at the two ends of the spacer bush and is in sliding fit with the outer sleeve. A tool body is arranged at the large end of the outer sleeve, and a tail flat structure matched with a drilling spindle transverse and flat hole is arranged at the small end of the outer sleeve; a guiding sleeve is arranged at one end of the guiding mandrel. According to the tool row with the movable centering shaft, a pipe hole of a workpiece to be machined is used as the centering benchmark, the defect that the radial force of the radial drilling machine spindle is insufficient is overcome, cutting rigidity is increased, the tool row has the machining advantages of being fast in moving, and good in view and conveniently, safely and reliably conducting clamping, and the machining advantages of the tool row are well developed. The tool row with the movable centering shaft is easy to manufacture, economical, applicable, and safe and reliable in operation, clamping, assembling and disassembling are convenient, the machining auxiliary time is shortened, and the labor productivity is improved.
Description
Technical field
The utility model belongs to Machining Technology field, relates to a kind of frock, especially for the centration axis packaged type blade row of radial drilling machine.
Background technology
The internal bore welding technology of bringing into use in chemical industry equipment manufacture in recent years, requires concentric welding groove and the heat exchanger tube butt welding of pore outside processing at tube sheet.
Take certain heat exchanger as example, and pipe tube sheet adopts internal bore welding mode to connect, and tube sheet material is 00Gr18Ni9Ti, and cutting ability is poor, has thousands of holes, and processing difficulties is that tube sheet pore outside has concentric 25 ± 0.05,4 * 6 welding groove, for and tube butt welding.This welding groove generally adopts Boring machine processing.As use Boring machine processing, first to complete the processing of whole pores, with each pore centering, with cutting knife, process again concentric 25 ± 0.05,4 * 6 welding grooves in outside, this just requires to want centering before each groove processing, loaded down with trivial details, the consuming time length of technique, and the processing charges of boring machine own are higher, it also has other processing tasks simultaneously, can not be occupied too of a specified duration.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and a kind of centration axis packaged type blade row proposing, for replacing Boring machine processing workpiece with drilling machine.
Main technical schemes of the present utility model: centration axis packaged type blade row, it is characterized in that comprising guiding mandrel, spacer and overcoat, guiding mandrel becomes to be slidably matched at overcoat endoporus and with overcoat by spacer bearings at both ends and spring fitting; The large end mounting cutter of overcoat, it is flat that the small end of overcoat is equipped with the tail coordinating with the horizontal flat hole of drill press spindle; Fairlead is installed in guiding mandrel one end.
Usually, described cutter is arranged on the large end of overcoat by screw.
The utility model frock be take workpiece pore as centering standard, can overcome radial drilling machine main shaft diameter to hypodynamic defect, increases cutting rigidity, bring into play it and move soon, convenient mounting and clamping, safety, reliably, processed edge that the visual field is good.
The utility model centration axis packaged type blade row is made simple, and economic and practical, handling safety is reliable, and clamping convenient disassembly reduces and processes non-cutting time, has improved labor productivity.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure, 1-fairlead; 2-cutter; 3-screw; 4-overcoat; 5-spacer; The 6-mandrel that leads; 7-bearing; 8-spring; 9-central spindle of the spring; 10-tail is flat.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.
Embodiment: the present embodiment centration axis packaged type blade row structure as shown in Figure 1, mainly comprise guiding mandrel 6, spacer 5 and overcoat 4, guiding mandrel 6 is arranged on overcoat 4 endoporus by spacer 5 bearings at both ends 7 and spring 8, and guiding mandrel 6 is slidably matched with 4 one-tenth, overcoat; The large end mounting cutter 2 of overcoat 4, the small end of overcoat 4 is equipped with the tail flat 10 coordinating with the horizontal flat hole of drill press spindle; Fairlead 1 is installed in guiding mandrel 6 one end.
It is benchmark that the present embodiment frock be take the spindle taper hole of radial drilling machine, utilizes the self-locking performance of pattern 5# tapering to be fixed on drill press spindle.
Tail flat 10 coordinates with the horizontal flat hole of drill press spindle, for clamping, dismantles.When guiding mandrel 6 is subject to resistance, it slides in the interior generation of overcoat 4 together with bearing 7, spacer 5, when removing axial resistance, guiding mandrel 6 is got back to original position together with bearing 7, spacer 5 under the thrust of spring 8, central spindle of the spring 9 plays spring 8 guide support effects (bearing and overcoat endoporus are slidably matched, and are mainly to prevent from blocking in dirt generations such as adding iron filings in man-hour); The large end of overcoat 4 is manufactured with the cutter groove of mounting cutter, and cutter 2 can be fastened in cutter groove by screw 3, and fairlead 1 external diameter can be made different sizes, for different pore size processing.
Operation: blade row is arranged in drill press spindle internal taper hole, by workpiece size requirement, fastening corresponding cutters is installed, adjust rotating speed and feed, by in fairlead 1 Inserting Tube plate hole, locking lathe, starts lathe feed to drawing requirement size, exits blade row and completes processing.
Use the utility model frock, improved existing machine tool mechanical processing characteristics, expand its range of work, can take manufactured endoporus as benchmark processing concentric circles, groove, R face etc., make full use of existing equipment and realize cost efficiency.
Claims (2)
1. a centration axis packaged type blade row, is characterized in that comprising guiding mandrel, spacer and overcoat, and guiding mandrel becomes to be slidably matched at overcoat endoporus and with overcoat by spacer bearings at both ends and spring fitting; The large end mounting cutter of overcoat, it is flat that the small end of overcoat is equipped with the tail coordinating with the horizontal flat hole of drill press spindle; Fairlead is installed in guiding mandrel one end.
