Abstract
The utility model relates to a mandrel, in particular to a distribution drill mandrel for couplings. The mandrel comprises fixture reserved shafts, a spindle and a projection, which are integrated parts lathed. The distribution drill mandrel for coupling is characterized in that a radial groove is arranged at the center of the spindle, an axial key groove is arranged on the outer wall of the spindle, the reserved shafts include a left one and a right one, the projection and the right reserved shaft are sequentially arranged at the right end of the spindle, and the left reserved shaft is arranged at the left end of the spindle. The distribution drill mandrel for coupling well functions in increasing machining precision of hinged holes on flange couplings and enables machining to be easier.
Description
Technical field:
The utility model relates to a kind of mandrel, and especially a kind of shaft coupling is joined the brill mandrel.
Background technology:
The precision direct relation of flanged joint processing the height of production efficiency, the processing flanged joint generally adopted half shaft coupling separate machined in the past, cause the manufacturing procedure complexity, machining accuracy is not high, now in order to make processing simple, and reach the precision needed, adopted a kind of technology of joining brill, the described brill of joining is mainly used in a kind of processing of processing the articulation hole of flanged joint, can use a kind of mandrel in joining the brill process, but mandrel need to guarantee can not mutually slide between two and half shaft couplings of flanged joint, and be easy to processing.
The utility model content:
The technical problems to be solved in the utility model is: the mandrel that provides a kind of and can fix, be easy to the flanged joint of processing.
In order to solve the above problems, we provide a kind of shaft coupling to join the brill mandrel, include the reserved axle of fixture, three parts of main shaft and boss, be one-body molded of turning, and the described alignment of shafts is provided with groove radially, spindle outer wall is provided with axial keyway, described reserved axle is divided into left obligation axle and right reserved axle, and described boss and right reserved axle are successively set on the right-hand member of main shaft, and the left obligation axle is arranged on the left end of main shaft.
Adopt flanged joint of the present utility model to join and bore being a little of mandrel: 1, owing to being provided with the reserved axle of fixture at the mandrel two ends, when joining brill, can fix half shaft coupling that need to join brill by fixture.Main shaft one side is provided with boss, allows two half a couplers be enclosed within on mandrel and is unlikely to come off, and can produce reaction joining while boring, make join drilled to effectively joining brill power; 2, because spindle outer wall is provided with axial keyway, utilize flat key to fix two and half shaft couplings, make two and half shaft couplings not produce dislocation; 3, because the alignment of shafts is provided with groove radially, to its objective is in order eliminating and to join the stress that the brill process produces.
Further, can axial restraint half shaft coupling for mandrel, described boss diameter is greater than main shaft.
Finally, in order to be fixed on mandrel on the fixture be complementary, described left obligation axle is identical with right reserved shaft size, and diameter is less than main shaft.
The accompanying drawing explanation:
Fig. 1 is that the shaft coupling of the utility model embodiment is joined the structural representation that bores mandrel;
Fig. 2 is the schematic cross-section of Figure 1A-A.
The specific embodiment:
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Shown in Fig. 1 and Fig. 2, shaft coupling of the present utility model is joined the brill mandrel, comprise that fixture reserves axle, main shaft 2 and boss 4, main shaft 2 centers are provided with groove 5 radially, and spindle outer wall is provided with axial keyway 3, the reserved axle of fixture is divided into left obligation axle 1 and right reserved axle 6, main shaft 2 right-hand members set gradually boss 4 and right reserved axle 6, and left end arranges left obligation axle 1, and shaft coupling is joined the brill mandrel by core material turning machine-shaping.Owing to being provided with the reserved axle of fixture at the mandrel two ends, when joining brill, can fix half shaft coupling that need to join brill by fixture.Main shaft 2 one sides are provided with boss 4, allow two half a couplers be enclosed within on mandrel and are unlikely to come off, and can produce reaction joining while boring, make join drilled to effectively joining brill power; Because main shaft 2 outer walls are provided with axial keyway 3, utilize flat key to fix two and half shaft couplings, make two and half shaft couplings not produce dislocation; Because main shaft 2 centers are provided with groove 5 radially, to its objective is in order eliminating and to join the stress that the brill process produces.
Can axial restraint half shaft coupling for mandrel, boss 4 diameters are greater than main shaft 2.
In order to be fixed on mandrel on the fixture be complementary, left obligation axle 1 and right reserved axle 6 are measure-alike, and diameter is less than main shaft 2.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not breaking away under prerequisite of the present utility model; can also make and somely not need to carry out creative work with regard to achievable improvement; these also should be considered as the protection domain of the utility model structure, and these can not affect effect and practical applicability that the utility model is implemented.
