Limitation.
Rotor shaft-inlet tooling in the related technology, there are shaft-inlet tooling length to fix, and be easy to cause in use process
The deficiencies of axis is hurt.For this purpose, the application provides a kind of adjustable length specification, motor shaft and cage rotor connection reliably and can protect
The rotor shaft-inlet tooling 100 of motor shaft.
Below with reference to Fig. 1-Fig. 6 description according to the rotor shaft-inlet tooling 100 of the utility model embodiment.
According to the rotor shaft-inlet tooling 100 of the utility model first aspect embodiment, comprising: tooling is trapped 1, tooling
Above set 2 and locking member 3.
Specifically, tooling trap 1 middle part be formed with axially through tooling trap 1 first shaft hole 11.For example, work
The middle part for loading set 1 could be formed with first shaft hole 11, and first shaft hole 11 can run through tooling along up and down direction shown in Fig. 1
Trap 1.
In tooling set 2 be set to tooling trap 1 top, and set 2 traps with tooling and 1 is connected in tooling, set 2 in tooling
Middle part is formed with the second axis hole 21 axially through set 2 in tooling.For example, the middle part of set 2 could be formed with second in tooling
Axis hole 21, the second axis hole 21 can cover 2 in tooling along up and down direction shown in Fig. 1.
Wherein, the second axis hole 21 and first shaft hole 11 can be adapted to pass through the second axis hole 21 and the with coaxial line, motor shaft 230
One axis hole 11, in this way, convenient for further realizing the cooperation of motor shaft 230 Yu cage rotor 220.
Locking member 32 is connected with set in tooling, and locking member 3, which can be located at tooling, trap and cover between 2 in 1 and tooling, under tooling
Set 1 is suitable for being locked by locking member 3, and locking member 3 can trap 1 locked position in locking fixture and release tooling is trapped
It is convertible between 1 releasing position, by adjust the adjustable tooling of locking member 3 trap 1 relative in tooling set 2 it is axial away from
From so that rotor shaft-inlet tooling 100 to enter shaft length adjustable.As a result, when needing to adjust into shaft length, it can will lock
The release of part 3 makes locking member 3 be in releasing position, convenient for further adjust tooling trap 1 with set 2 in tooling along it is axial relatively away from
From consequently facilitating adjusting rotor shaft-inlet tooling 100 enters shaft length, versatility is good, and then solves different in the related technology
The many kinds of technical problem of tooling between model motor.
According to the rotor shaft-inlet tooling 100 of the utility model embodiment, by adjusting the adjustable tooling of locking member 3
Trap 1 axial distance relative to set 2 in tooling so that rotor shaft-inlet tooling 100 to enter shaft length adjustable.As a result, when
When needing to adjust into shaft length, locking member 3 can be unclamped, by adjust tooling trap 1 in tooling set 2 along axial direction it is opposite
Distance enters shaft length convenient for adjusting rotor shaft-inlet tooling 100, and versatility is good, so as to solve in the related technology not

Substantial advance and advantage: the adjustable of tooling length may be implemented, pass through and unclamp locking nut, cooperate vernier caliper, adjust
Tooling is to predetermined length, then tightens locking nut realization.Motor shaft 230 and metal material has been isolated in bushing 4 in tooling in set 2
The tooling of part avoids axis wound.When the boss 13 of tooling bottom enters axis riveting, cage rotor 220 is made to generate micro-strain, increased
The binding force of cage rotor 220 and motor shaft 230, cage rotor 220 are not easy to loosen with motor shaft 230.
The utility model delicate structure, easy to use, shaft-inlet tooling adjustable in length, a tooling can be applicable in a variety of types
Number rotor assembly, versatility is good, and 2230 pine of axis wound and cage rotor 220 and motor shaft caused by avoiding during axis
De- risk.
It describes to enter axis process according to the rotor shaft-inlet tooling 100 of the utility model embodiment with reference to the accompanying drawing.
Tooling base 210 is placed on the workbench of hydraulic press first, then puts cage rotor 220, cage rotor 220
The cooperation of fan blade inner ring surface and 210 upper end crest clearance of tooling base play the role of positioning so that tooling base 210, cage rotor
220 axis is overlapped；Place into length adjustment completion shaft-inlet tooling 100, tooling trap 1 outer diameter and 220 aluminium of cage rotor
Ring internal diameter clearance fit plays the role of positioning, so that the axis of cage rotor 220 is consistent with the axis of shaft-inlet tooling 100, motor shaft
230, which cover 2 from tooling, is put into；Start hydraulic press, pressure head 240 moves down, and motor shaft 230 is pressed into cage rotor 220, mouse
The internal diameter and 230 annular knurl position outer diameter of motor shaft of cage rotor 220 are interference fitted, and hydraulic press reaches predetermined pressure (the pre- level pressure
Power can according to need specific setting) after automatically reset, complete motor shaft 230 and enter axis process.
Here, the predetermined pressure can be configured by the operation interface of the hydraulic press and by the control of the hydraulic press
Device processed is controlled, this will be understood by for a person skilled in the art.
