Fast transforms suit on the basis of the internal diameter of pole iron core, if after being pressed the stator of 2 pole iron cores, needing replacing determining for 4 pole iron cores
The period of the day from 11 p.m. to 1 a.m, so that it may be arranged the suit of a corresponding size in original stator fixing mould 170, can be consolidated by bolt
Fixed, replacement is convenient, and production efficiency can be improved, improve the quality of press fitting.
Present embodiment also provides a kind of stator and casing pressing method, is mainly pressed using said stator and casing
The press fitting process of device 100 completion stator and casing, and the following steps are included:
Step 1: adjusting the centre-height of casing using lifting platform 150, make the centre-height of itself and casing fixing mould 140
It is equal.
Step 2: casing is set in casing fixing mould 140.
Certainly, it needs that casing is first called in workspace sidewards, passes through lifting platform 150 on workbench and workspace side
Casing fixing mould 140, utilize casing seam allowance positioning.
Step 3: stator is set in stator fixing mould 170.
Certainly, it needs that the stator with winding is first lifted up into workspace sidewards, is located in by the inner circle on the iron core of stator
In stator fixing mould 170.
Step 4: stator is pressed into casing by control hydraulic press 160.
Hydraulic press 160 is operated, stator is pressed into casing sidewards.Finally, the assembly of stator and casing is hung workspace.
Opening up due to workspace, stator, casing and the two assembly pressed can be passed in and out very easily
Workspace also eliminates the assembly being pressed and is turned to the process laid flat, improves production efficiency.
It is easily understood that the operation of step 1 can be omitted if the script height of lifting platform 150 has been met the requirements.
There is no stringent successive requirements for step 2 and step 3, can mutually exchange or carry out simultaneously.
Stator provided in this embodiment and casing press-loading apparatus 100, firstly, horizontal press-loading process can be completed, compared with biography
The vertical press-loading process of system, simple to operate, a people can be easily accomplished, and reduce cost of labor.Secondly, stator and
Casing is separately fixed in stator fixing mould 170 and casing fixing mould 140, and before press fitting, stator is not contacted with casing,
It is possible to prevente effectively from the winding and casing wiping on stator are touched and damaged, the quality of motor ensure that.Then, casing fixing mould
140 and lifting platform 150 cooperation, can quick to casing, accurately position.Finally, workspace is opening up, nothing is blocked, it is
Open form, stator and casing with winding can be lifted directly into machine workspace, in operator's operating process without erecting
There is no visual angle blind zone, further avoids personal injury and damaged products.
