Abstract
The utility model belongs to a metal machining cutter, and particularly relates to a cutter for removing burr at a port of a cladding tube of a fuel rod, which comprises a cutter body. The cutter body is provided with two R-shaped cutter edges which are symmetrical to the axis of the cutter body. The cutter has the following advantages: as the cutter is provided with two cutter edges, during the process of removing burr at the port, the two cutter edges are respectively used for removing the burr inside the tube and the burr outside the tube, the changing of cutter during the using process is avoided, simultaneously the clamping on a lathe saddle is convenient, and the automatic control on removing the burr can be realized by a numerical control lathe, thus improving the burr removing quality, reducing the labor intensity of operators, and enhancing the quality of the port.
Description
Technical field
The utility model belongs to a kind of metal cutting process tool, is specifically related to a kind of cutter of removing fuel rod clad pipe mouth of pipe burr.
Background technology
The fuel rod clad pipe needs fixed length processing, and there is burr in the mouth of pipe behind the customized cut-off, and the existence of burr is totally unfavorable to follow-up tamponade and fuel rod boxing quality, and burr is removed too much, forms chamfering, to fuel rod clad tubular construction and the same serious consequence that produces of welding.Burr is removed the employing artificial removal at present, and the burr of use is removed cutter following two kinds, and a kind of is that the burr that adopts hacksaw blade to grind is removed cutter, and each cut-out back people on lathe remove by hand; Another kind is to adopt existing molding cutter to remove interior burr earlier, removes outer burr again.
The deficiency that existing removal burr method exists:
1. the defective that different cutters exist: molding cutter is removed burr and mark vestige easily on inwall; The self-control cutter grinds difficulty, and service life is very short.
2. artificial removal's burr strength is inhomogeneous, causes mouth of pipe burr to remove the quality instability; Simultaneously, it is different that different personnel operation burrs are removed situation.
3. personnel labor intensity is big, easily because of fatigue causes the action distortion, causes product quality to descend in the operating process.
Summary of the invention
The purpose of this utility model provides the manual deburring mouth of pipe of a kind of solution quality instability problem, the cutter of the removal fuel rod clad pipe mouth of pipe burr of alleviate operator's labour intensity simultaneously, raising labour productivity.
The utility model is achieved in that a kind of cutter of removing fuel rod clad pipe mouth of pipe burr, and it comprises cutter hub, and cutter hub is provided with blade.
Described blade is two blades that are shaped as " R " shape, and symmetrical with the axis of cutter hub.
The utility model has the advantages that, because this cutter has two blades, in the process of removing mouth of pipe burr, available two blades are removed burr and the outer burr of pipe in the pipe respectively, avoid in the process of using, changing cutter, be convenient to clamping on the lathe saddle simultaneously, can realize the automatic control that burr is removed by numerically controlled lathe, remove quality and alleviate operator's labour intensity thereby improve burr, improve the quality of the mouth of pipe.
Description of drawings
Fig. 1 is a kind of cutter schematic diagram of removing fuel rod clad pipe mouth of pipe burr provided by the utility model.
Among the figure, 1 cutter hub, 2 blades.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail:
As shown in Figure 1, a kind of cutter of removing fuel rod clad pipe mouth of pipe burr, it comprises cutter hub 1, cutter hub 1 is provided with blade 2.Blade 2 is two blades that are shaped as " R " shape, and symmetrical with the axis of cutter hub 1.The angle of the circular arc of blade 2 can be adjusted according to the diameter of processed pipe.
In order to check effect of the present utility model whether can meet the demands, at first cut out 10 samples and carry out sample production and assessment experiment.Methods such as the visualize of upchecking of sample, tamponade check tamponade quality, Welding Testing interface quality are carried out, and see Table 1.
Table 1 sample evaluation form
| Project | Visualize | The tamponade check | Welding Testing |
| Detection method | Observe the mouth of pipe and have or not burr, chamfering, scrape the mouth of pipe with cotton swab and check burr, check the burr removal effect | Check the fit-state of end plug and involucrum pipe after the tamponade; Have or not obvious torticollis phenomenon. | Inspection has or not defectives such as evagination, indent, pore, inflatable |
| The assessment effect | No burr, the no chamfering of range estimation | No torticollis, tooled joint are fitted closely | There is not the welding defective |
Test by the adjustment of deburring technology, show that the two R type cutters removal of usefulness mouth of pipe burr holding functions can realize design object in advance, promptly can use two cutting edges of two R type cutters, realize the disposable removal of finishing the inside and outside burr of the involucrum pipe mouth of pipe by programme-control, and, can reach the full-automatic function that the involucrum pipe mouth of pipe is removed burr fully by the control of tool feeding amount and lathe spindle rotating speed.
Claims (2)
1. cutter of removing fuel rod clad pipe mouth of pipe burr, it is characterized in that: it comprises cutter hub (1), cutter hub (1) is provided with blade (2).
2. a kind of cutter of removing fuel rod clad pipe mouth of pipe burr as claimed in claim 1 is characterized in that: described blade (2) is two blades that are shaped as " R " shape, and symmetrical with the axis of cutter hub (1).
