Abstract
The utility model belongs to the technical field of the water pump apparatus, especially, relate to a water pump pump shaft structure. The utility model discloses a water pump pump shaft structure, water pump pump shaft structure is provided with a plurality of external tooths including the spline tooth tip of light tip with the tensile technology one shot forming of adoption extrusion on the outer wall of handing -over department of light tip and spline tooth tip, smooth tip and handing -over department of spline tooth tip be provided with the impeller position sleeve, be provided with on the inner wall of impeller position sleeve and adopt disposable crowded shaping internal tooth, the internal tooth and external tooth phase -match of drawing in center location. The beneficial effects of the utility model are that: can guarantee the intensity of pump shaft, can guarantee the depth of parallelism and the intensity of impeller location again, and shorten the simple swift of process time and process.
Description
Technical field
The utility model belongs to water pump apparatus technical field, particularly relates to a kind of Pump Axle structure.
Background technique
Existing MODEL VERTICAL MULTISTAGE PUMP, on pump shaft project organization, itself and impeller mating part, great majority adopt cutting technology, after cutting, pump shaft tensile strength weakens, and, due to cutting, its size and tolerance wayward, surface roughness value is large, greatly have impact on original performance during former polished rod.
The pump shaft structure of existing MODEL VERTICAL MULTISTAGE PUMP, on impeller location, after groove is cut in some employings, be bumped into steel wire, mix positioning wrap, fix impeller axial dimension, this kind of design proposal, as cut groove width, then pump shaft intensity is poor; Cut groove little, then steel ring is thin, and impeller positioning intensity is poor.What have cuts out several facets with cutting method, and equally, plane of orientation is little, and impeller positioning intensity is weak, and the unified planeness of several planes can not ensure, have impact on the positioning intensity of pump shaft.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, a kind of intensity that can ensure pump shaft is provided, can ensure again the parallelism that impeller is located and intensity, and shorten the Pump Axle structure of the simple and fast of process time and operation, its technological scheme is as follows:
Pump Axle structure, is characterized in that, described Pump Axle structure comprises light end portion and adopts the one-time formed spline tooth end portion of extrusion stretching technique, and the outer wall of the jointing place of light end portion and spline tooth end portion is provided with some external tooths; Described light end portion and the jointing place of spline tooth end portion are provided with impeller setting sleeve, and the inwall of impeller setting sleeve is provided with the internal tooth adopting the disposable pultrusion process of centralized positioning, internal tooth and external tooth match.
Optimal way is, described light end portion is provided with the pin-and-hole of the installation dimension for adjusting impeller in pump.
Optimal way is the screw thread that described spline tooth end portion is provided with for fixing impeller axial position.
The Pump Axle structure that the utility model provides, when in use, adopts the Main Function of the one-time formed spline tooth end portion of extrusion stretching technique to be the increase in the tensile strength of pump shaft, decreases the roughness value of spline tooth part.In the outer wall of the jointing place of light end portion and spline tooth end portion arranges some external tooths, one extrusion die efficiently can be designed, disposablely on the outer wall of jointing place, form several external tooth planes and external tooth planar smoothness is unified, thus avoiding owing to repeatedly cutting in background technique, the off plumb of multiple end face and shaft centre line may.Adopt the internal tooth of the disposable pultrusion process of centralized positioning can match with external tooth, ensure that the perpendicularity of impeller setting sleeve and pump spindle center line, meanwhile, because multiple internal tooth plane once extrudes, also ensure that its intensity of locating.Owing to have employed one-shaping technique, so shorten process time and operation.
The utility model is further provided with pin-and-hole, for adjusting the installation dimension of impeller in pump.
The utility model is further provided with screw thread, for fixing impeller axial position.
The beneficial effects of the utility model are: the intensity that can ensure pump shaft, can ensure again the parallelism that impeller is located and intensity, and shorten the simple and fast of process time and operation.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of impeller setting sleeve.
Embodiment
Embodiment is illustrated below in conjunction with Fig. 1 and Fig. 2:
Pump Axle structure, described Pump Axle structure comprises light end portion 1 and adopts the one-time formed spline tooth end portion 2 of extrusion stretching technique, the outer wall of the jointing place of light end portion 1 and spline tooth end portion 2 is provided with some external tooths 3; Described light end portion 1 and the jointing place of spline tooth end portion 3 are provided with impeller setting sleeve 4, the inwall of impeller setting sleeve 4 are provided with the internal tooth 5 adopting the disposable pultrusion process of centralized positioning, and internal tooth 5 and external tooth 3 match.Described light end portion 1 is provided with the pin-and-hole 6 of the installation dimension for adjusting impeller in pump.Described spline tooth end portion 2 is provided with the screw thread 7 for fixing impeller axial position.
When in use, in order to realize above-mentioned purpose of design, design a fixture, customized one
Plant the process equipment matched with it, disposable extruding drawing spline tooth end portion, greatly reduces manufacturing procedure, significantly improves manufacturing efficiency.In part roughness value, many producers before, the machine cut processing of employing, roughness value is uncontrollable with this, and adopt extruding drawing, part surface and raw material are almost suitable.Meanwhile, it also avoid the cutting due to material in background technique, weakening of pump shaft tensile strength properties.
The jointing place of light end portion 1 and spline tooth end portion 3, design one extrusion die efficiently, disposablely forms several external tooth planes and external tooth planar smoothness is unified in jointing place.Avoid owing to repeatedly cutting in background technique, the off plumb of multiple end face and shaft centre line may.
