Abstract
The invention belongs to the technical field of tools for a water pump, and particularly relates to a water pump shaft structure. The water pump shaft structure comprises a smooth end and a spline tooth end which is formed in a one-off mode through an extruding and drawing process. Multiple outer teeth are arranged on the outer wall of the joint of the smooth end and the spline tooth end. An impeller locating sleeve is arranged at the joint of the smooth end and the spline tooth end. Inner teeth which are located at the center and formed in a one-off extruding and drawing mode are arranged on the inner wall of the impeller locating sleeve. The inner teeth are matched with the outer teeth. The water pump shaft structure has the advantages that the strength of the pump shaft can be guaranteed, the parallelism and the strength of locating of an impeller can also be guaranteed, the machining time is shortened, and the process is simple and rapid.
Description
Technical field
The invention belongs to water pump apparatus technical field, particularly relate 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 object of the invention 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.
Pump Axle structure provided by the invention, 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 present invention is further provided with pin-and-hole, for adjusting the installation dimension of impeller in pump.
The present invention is further provided with screw thread, for fixing impeller axial position.
The invention has the beneficial effects as follows: the intensity that can ensure pump shaft, the parallelism that impeller is located and intensity can be ensured again, and shorten the simple and fast of process time and operation.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
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.
