It includes base and dabber, dabber and base spline clearance fit, the spindle terminal surface be provided with load -bearing platform, be connected with holding screw in this load -bearing platform's center to the cooperation has corresponding gland nut and rebasing nut. The utility model discloses an outer circular slot of carbide ring processing frock through base, dabber, load -bearing platform, gland nut, holding screw's cooperation, has solved the problem that the position degree is easy overproof, the product percent of pass is lower and production efficiency hangs down that exists in the processing of the outer circular slot of carbide ring, have simple structure, convenient to use, characteristics with low costs in addition.
Description
Technical field
The utility model relates to a kind of cold working frock, especially a kind of frock being mainly used in the peripheral groove processing of metal ring body.
Background technology
In the processing of metal ring body, during particularly the peripheral groove of carbide ring is processed, position degree requires quite high.At present for the employing of this type of circle product external slot machining is linear cutter mode, product is placed on Linear cut workbench, with pressing plate, product is compressed, due to the restriction of workbench, the mode of sparking can only be adopted manually to use the center of molybdenum filament centering circle product external, centered by cylindrical, start cutting groove.Owing to there being pressing plate to block molybdenum filament as obstacle, when needing to stop processing after well cutting part groove, take off molybdenum filament, take pressing plate, the cleavage of wire cutting machine tool navigates to new position, again tightens silk, starts cutting process, starts the groove cutting other.There is some defect in this kind of cutting mode: the error of manual alignment is comparatively large, increases the error of product space degree after processing; The benchmark disunity of machining benchmark and drawing requirement, machining benchmark is cylindrical, and the benchmark of drawing requirement is endoporus, due to benchmark disunity, increases the rear product space degree error of processing; Each part product all wants manual centering center, and will be interrupted in process, needs upper and lower silk, causes working (machining) efficiency lower.Due to the defect of above several aspect, not only qualification rate is low for this series products grooving operation, and working (machining) efficiency is also very low.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is: provide that a kind of structure is simple, long service life, dismounting and change carbide ring peripheral groove processing tool easily.
In order to achieve the above object, the utility model is achieved through the following technical solutions: carbide ring peripheral groove processing tool, comprise base and mandrel, described mandrel coordinates with base spline gaps, described mandrel upper surface is provided with carrying platform, be connected with holding screw in the center of this carrying platform, and be combined with corresponding clamp nut and rebasing nut.
The key number of teeth that spline gaps coordinates is multiple, and is circumferentially uniformly distributed.
The gap that described mandrel coordinates with base spline gaps is 0.01-0.02mm.
The beneficial effects of the utility model are: carbide ring peripheral groove processing tool of the present utility model, by the cooperation of base, mandrel, carrying platform, clamp nut, holding screw, solve the position degree that exists in the processing of carbide ring peripheral groove easily overproof, product percent of pass is lower and the problem that production efficiency is low, and has the advantages that structure is simple, easy to use, cost is low.The key number of teeth coordinated due to spline gaps is multiple, and is circumferentially uniformly distributed, and quite easily according to a fixed value rotary core shaft, can facilitate the accurate processing of peripheral groove.The gap coordinated with base spline gaps due to described mandrel is 0.01-0.02mm, improves precision, reduces mismachining tolerance.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of carbide ring peripheral groove processing tool of the present utility model;
Fig. 2 is the structural representation of a kind of base of carbide ring peripheral groove processing tool of the present utility model;
In figure, 1-base, 2-mandrel, 3-carrying platform, 4-clamp nut, 5-workpiece, 6-holding screw, 7-rebasing nut.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1 and Figure 2, carbide ring peripheral groove processing tool of the present utility model, comprise base 1 and mandrel 2, described mandrel 2 coordinates with base 1 spline gaps, described mandrel 2 upper surface is provided with carrying platform 3, be connected with holding screw 6 in the center of this carrying platform 3, and be combined with corresponding clamp nut 4 and rebasing nut 7.Carbide ring peripheral groove processing tool of the present utility model, by the cooperation of base 1, mandrel 2, carrying platform 3, clamp nut 4, holding screw 6, solve the position degree that exists in the processing of carbide ring peripheral groove easily overproof, product percent of pass is lower and the problem that production efficiency is low, and has the advantages that structure is simple, easy to use, cost is low.During use, base 1 is fixed on the workbench of wire cutting machine, mandrel 2 is coordinated with base 1 spline interval, being placed in by rebasing nut 7 is sleeved on carrying platform 3, place work piece 5 is with on rebasing nut 7, holding screw 6 is connected to carrying platform 3 center through workpiece 5 with rebasing nut screw connection, then on turn clamp nut 4 workpiece pressing 5, now workpiece 5 is connected with rebasing nut 7, holding screw 6, clamp nut 4, carrying platform 3 and mandrel 2 is an entirety, start line is cut, carry out the processing of workpiece 5 peripheral groove, quite convenient.After processing a peripheral groove, upwards extract the entirety that workpiece 5 connects into rebasing nut 7, holding screw 6, clamp nut 4, carrying platform 3 and mandrel 2, rotate certain spline tooth number, and then coordinate with base 1, carry out the processing of next peripheral groove, quite convenient.
As preferably, the key number of teeth that spline gaps coordinates is multiple, and is circumferentially uniformly distributed, and quite easily according to a fixed value rotary core shaft 2, can facilitate the accurate processing of peripheral groove.It should be noted that the key number of teeth of spline needs the number setting of the peripheral groove of processing according to workpiece 5, the number as the peripheral groove needing processing is six, then the key number of teeth of spline can be set to the multiple of six, as six, 12.If be set to six, then after machining a peripheral groove, only need rotate the position of a key tooth.
As preferably, the gap that described mandrel 2 coordinates with base 1 spline gaps is 0.01-0.02mm, improves precision, reduces mismachining tolerance.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
