Abstract
The utility model discloses an inside spherical machining tool of an impeller shell. The inside spherical machining tool comprises a turning cutter (5) and a cutter rod (1). The inside spherical machining tool is characterized by further comprising a connection base (4), the turning cutter (5) is fixedly arranged at one end of the cutter rod (1), the other end of the cutter rod (1) is hinged to the connection base (4), and a cutter row base (2) is arranged in the middle of the cutter rod (1). The inside spherical machining tool of the impeller shell is simple in structure, safe in use, low in cost, simple, convenient to use and feasible.
Description
Technical field
The processing tool of the impeller housing of the utility model axial-flow pump, a kind of endosphere processing tool of impeller housing specifically.
Background technology
The difficulty of processing of blade wheel chamber's Internal Spherical Surface is large, and the quality of crudy is larger on the hydraulic performance impact of pump.In prior art, adopt adjusted the mode working inner sphere that angle approaches circular arc as far as possible more, or adopts Maching Center During Maching Spherical Surface.Adopt and adjust the mode working inner sphere that angle approaches circular arc as far as possible, its machining accuracy is lower, and the cambered surface processed and circular arc still have no small distance.Adopt the machining center Internal Spherical Surface, although its machining accuracy can meet the demands, its processing cost is too high, does not meet modern crafts and produces low cost, high-quality, high efficiency requirement; Simultaneously, because the physical dimension of pump is not of uniform size, each is variant for shape, thus processing method also each is variant, the impeller size of large flow axial-flow pump is larger, even machining center also is difficult to processing sometimes, therefore is necessary to be improved.
Summary of the invention
The purpose of this utility model is to provide a kind of endosphere processing tool of impeller housing, to solve the problems of the technologies described above.
To achieve these goals, the technical solution of the utility model is: a kind of endosphere processing tool of impeller housing, comprise lathe tool and knife bar, it is characterized in that: also comprise Connection Block, described knife bar one end is fixedly installed lathe tool, the knife bar other end and Connection Block are hinged, and the centre of knife bar is provided with the blade row seat.
In technique scheme, its operation principle is: axial-flow pump impeller shell to be processed is filled on lathe, knife bar is overlapped with the centre of sphere of the Internal Spherical Surface of impeller housing with the hinged place of Connection Block, then make the rotation of lathe drives impeller shell, by the blade row seat, make knife bar take the hinged place of knife bar and Connection Block and do the cambered surface motion as the center of circle, thereby make the lathe tool be connected with knife bar also do the cambered surface motion, and then process the Internal Spherical Surface met the demands.
Described knife bar and Connection Block are hinged by connecting pin.
To sum up, this impeller housing car endosphere tool structure for processing is simple, uses safety, and cost is low, simple and feasible.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-knife bar in figure, 2-blade row seat, 3-connecting pin, 4-Connection Block, 5-lathe tool, 6-impeller housing.
The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not form to restriction of the present utility model, only for example.By explanation, make advantage of the present utility model become more clear and easily understand simultaneously.
Consult accompanying drawing known: as shown in Figure 1, a kind of endosphere processing tool of impeller housing, comprise lathe tool 5 and knife bar 1, it is characterized in that: also comprise Connection Block 4, described knife bar 1 one ends are fixedly installed lathe tool 5, and the knife bar other end and Connection Block 4 are hinged, and the centre of knife bar 1 is provided with blade row seat 2.
In technique scheme, its operation principle is: axial-flow pump impeller shell 6 to be processed is filled on lathe, knife bar 1 is overlapped with the centre of sphere of the Internal Spherical Surface of impeller housing 6 with the hinged place of Connection Block 4, then make 6 rotations of lathe drives impeller shell, by blade row seat 2, make knife bar 1 take knife bar 1 and do the cambered surface motion as the center of circle with the hinged place of Connection Block 4, thereby make the lathe tool 5 be connected with knife bar 1 also do the cambered surface motion, and then process the Internal Spherical Surface met the demands.
Described knife bar 1 is hinged by connecting pin 3 with Connection Block 4.
To sum up, this impeller housing car endosphere tool structure for processing is simple, uses safety, and cost is low, simple and feasible.
Other unspecified part all belongs to prior art.
