Description
Technical field
The utility model belongs to mechanical water pump and makes processing technique field, relates to a kind of frock clamp of process water impeller of pump.
Background technology
Water pump vane is the vitals of dynamic power machine, the stability of the operating efficiency that its machining accuracy directly influences water pump during with operation.Because the outside dimension of impeller is bigger; Blade tip is sphere (cambered surface), and when these blades intersected and be vertical at blade handle center line and impeller rotating shaft line, the cambered surface of its end was to be on the sphere of the centre of sphere at an intersection point with blade handle center line and impeller rotating shaft line; But for reducing difficulty of processing and cost; Raising the efficiency, actually add man-hour, is that the blade tip cambered surface is processed as on the face of cylinder with the axle center of impeller rotating shaft line.Because the outside dimension of impeller is bigger, blade is very thin, thus the face of cylinder that processes can be similar to regard sphere as, as the cambered surface of blade tip.But when these blades are installed on the hub body, its root center line and impeller rotating shaft line and out of plumb, but certain angle of inclination (see figure 1) is arranged.The impeller of different water pump types and different specific revolutions; The angle of inclination of its blade centreline and blade revolving shaft line has nothing in common with each other, and like axial-flow pump impeller, its blade centreline and blade revolving shaft line angle of inclination are 90 °; Specific revolution is 400 mixed-flow pump impeller; Its blade centreline and blade revolving shaft line angle of inclination are 54.6 °, and specific revolution is 500 mixed-flow pump impeller, and its blade centreline and blade revolving shaft line angle of inclination are 58 °.
When being processed with the water pump blade end cambered surface at angle of inclination; Its machining locus also tilts; Lathe tool plate palpus inclination respective angles on the lathe, so that the blade tip cambered surface that processes is vertical with blade handle center line, difficulty of processing is bigger; Be prone to mismachining tolerance, and the spherical diameter that processes can't be measured directly.In the prior art, often utilize pattern and process and measure by means of model.Therefore, working (machining) efficiency is low, and machining accuracy is not high, thereby influences the raising of pump working efficient.For the less blade tip cambered surface of spherical diameter size; Often utilize lathe in machining; Though effectively improved the machining accuracy of blade tip cambered surface; But the non-cutting time of clamping, correction, tool setting etc. is longer, and it is bigger so just can't to satisfy production lot, the working condition that working (machining) efficiency is had relatively high expectations.And for larger-diameter blade tip cambered surface, obviously higher with numerical-control processing method processing to the working ability requirement of numerically controlled lathe, improved processing cost.As use engine lathe processing, and because the angle of inclination of blade is difficult to accurately hold, make blade be difficult to guarantee in the precision that adds man-hour, can't process satisfactory blade tip cambered surface.
Summary of the invention
Technical problem:The utility model provides the frock clamp of the blade tip cambered surface that is used for the process water impeller of pump that a kind of engine lathe capable of using, working (machining) efficiency are high, precision is good.
Technical scheme:The frock clamp of the blade tip cambered surface that is used for the process water impeller of pump of the utility model; Comprise disk, an end face of disk is provided with the circular flange coaxial with it, and the circle diameter of flange is less than the diameter of disk; Another end face of disk is provided with the blade fixing body of ring-type; Be symmetrically arranged with at least three installing holes on the blade fixing body, axially intersecting of the axial and blade fixing body of installing hole is also vertical, and the aperture of installing hole and axial depth and water pump blade handle are complementary.
In the utility model, blade fixing body arranged outside has and the corresponding locating surface of installing hole, and installing hole (31) is positioned at the center of locating surface, and the geomery of the shank shaft shoulder of locating surface and water pump blade is complementary.
When adopting apparatus of the present invention processing blade tip cambered surface; The blade handle center line of blade was become the axial (see figure 5) perpendicular to the blade fixing body by favouring revolution hub body 5 center line (see figure 1)s originally,, make the sphere centre point be positioned on the blade fixing body centre of gyration line promptly perpendicular to lathe centre of gyration line; The machining locus of point of a knife has formed a face of cylinder; With this face of cylinder approximate regard sphere as, as the blade tip cambered surface, i.e. the spherical diameter tactical diameter that equals to process.
Beneficial effect:The utility model compared with prior art has following advantage:
After using the frock clamp of the utility model; Slanted angle with root center line and impeller rotating shaft line; It is vertical with the impeller rotating shaft line to be adjusted into blade handle center line; The cambered surface of blade tip is exactly to be on the sphere of the centre of sphere at one with blade fixing body central point like this, at this moment the distance of blade tip and blade fixing body central point be adjusted into blade tip with the distance of hub body central point, can on machine tool, process satisfactory end cambered surface.
After blade is installed on the frock clamp of the utility model; On lathe, add man-hour, the movement locus of blade tip for repeating to turn round cutting movement, can guarantee that the Cutting trajectory of cutter is consistent with the blade tip cambered surface with respect to process tool; End cambered surface mismachining tolerance is little; Crudy is high, effectively improves processing of leaves precision and production efficiency, has improved pump efficiency simultaneously.
When utilizing the frock clamp processing blade tip cambered surface of the utility model, can in process of manufacture, directly measure the processing dimension of blade tip cambered surface, and the end cambered surface that can on engine lathe, process the different size blade, reduced processing cost.Because technological process is simple, machining accuracy is controlled easily, and the utility model device capable of using carries out end cambered surface processing to larger-size impeller on engine lathe.
Tighten up after plate is fixed with blade between frock clamp of the utility model and the blade to be processed; Blade just is fixedly installed on the blade fixing body; It is the parts that blade uses when being installed on the impeller hub body that this blade tightens up plate, need not increase new part, simple in structure; Make, install easily, versatility is good.
