Description
Technical field
The utility model belongs to magnetic drive pump rotor technology field more particularly to a kind of liquid pump PM rotor.
Background technique
Permanent magnet liquid pump rotor is widely used in all trades and professions, and applicant is directed to permanent magnet liquid pump rotor,
Obtain two patents, application number is respectively CN200620110026.2 and CN200820097638.1, two patents and other
Although relevant patent respectively has innovative point, also there is deficiency：For example, having the waste problem of the permanent magnet of crackle, same permanent magnetism
Body material improves the problem of performance, the diversification of permanent magnet external protection material, and when location hole of processing rotor is easy to produce hair
It pierces and the overlap problem that lead to production efficiency low.
Utility model content
The purpose of this utility model is to provide a kind of liquid pump PM rotors to make to infuse to solve existing straight hole technique
Each location hole position on rotor after modeling processing generates a large amount of burr and overlap, staff need to be removed burr again
With the process of overlap, increase many workloads, leads to the problem that production efficiency is lower, and presentation quality is caused to decrease.
In order to achieve the above object, the base case of the utility model is：Liquid pump PM rotor, including shaft, enclose
The permanent magnet being distributed around the shaft, the permanent magnet are equipped with clad, and shaft is located in clad, the periphery of clad and end
There is location hole on face, the both ends of location hole offer chamfering.
The beneficial effect of this base case is：By the way that chamfering is arranged on mold location hole, make in the middle part of location hole and wraps
It will form ladder transition section between clad surface, a guiding can be played the role of when positioning pin assembles, be convenient for positioning pin
Into location hole, accurate positioning and location efficiency are high；And by the way that chamfering is arranged on mold, so that processing location hole clad
The inner surface and the outer surface will not generate burr and overlap, the process for reducing follow-up work personnel deburring and overlap, greatly
Improve production efficiency.
Further, the chamfering of one end far from permanent magnet is outer chamfer, and the chamfering close to one end of permanent magnet is inner chamfer.
Further, the permanent magnet be a monolith cylindric permanent magnet or for by multi-disc magnet combination at cylindric
Permanent magnet, so set, for multistage magnetic induction rotor, so that the magnetic induction intensity of every grade of magnet is higher after magnetizing, to lead
Cause the magnetic force of entire rotor transmitting bigger.
Further, the clad is to be integrally fixed by way of injection molding or die casting with permanent magnet.
Further, outer chamfer and inner chamfer are R chamfering or C chamfering, can be adapted for different positioning pins.
Further, the permanent magnet is made of permanent-magnet ferrite or rare earth permanent-magnetic material, to adapt to different demands, mentions
High performance-price ratio.
Further, the permanent magnet is intact permanent magnet or is permanent magnet there are crackle, so set, can be with
The recycling for realizing damaged permanent magnet, has saved production cost at the problem of avoiding waste.
Further, the material of clad is non-magnet material.

As shown in Figure 1 and Figure 2, a kind of liquid pump PM rotor, the permanent magnet 4 including shaft 5 and six magnets composition,
The permanent magnet 4 that six magnets are constituted is cylindrical shape, and permanent magnet 4 is made of permanent-magnet ferrite.Inside, the outside and two of six magnets
End is equipped with the clad 1 that is integrally fixed, clad 1 by being integrally fixed by way of injection molding with permanent magnet 4,
The clad 1 is plastic layer.Shaft 5 is fixedly connected on the middle part of clad 1.Permanent magnet 4 is intact or with splitting
The clad 1 of permanent magnet 4 is coated, so as to realize breakage by the permanent magnet 4 of the small defect such as line by way of injection molding
Permanent magnet 4 recycling, the problem of avoiding waste.
Several location holes 2 are offered on the upper surface of clad 1, lower surface and right side, location hole 2 is far from permanent magnet
4 one end offers outer chamfer 3, and location hole 2 offers inner chamfer 6 close to one end of permanent magnet 4, outer chamfer 3 in the present embodiment
It is the angle R with inner chamfer 6, location hole 2 is pin hole.
Embodiment 2
As shown in figure 3, the present embodiment the difference from embodiment 1 is that, permanent magnet 4 be a monolith cylindric permanent magnet
4, the outer chamfer 3 and inner chamfer 6 of location hole 2 are the angle C, and location hole 2 is threaded hole, and the clad 1 is that copper or aluminium etc. are non-
