Embodiment two:
It please refers to shown in Fig. 1-10, present embodiments provides using inclined shaft class motor assembly tooling described in embodiment one
To the method that inclined shaft class motor is assembled, the inclined shaft class motor assembly method the following steps are included:
S101, bracket 12 is mounted on workbench 11, the first locating slot 112 keel 13 being put on workbench
It is interior；
Specifically, bracket is bolted with workbench in the present embodiment, is selected according to the size of pre-assembled motor case
The installation site of bracket is taken, keel is packed into the first locating slot on workbench, and the position of keel will guarantee motor case
It can be placed in the upper surface of keel first end, the second end of keel protrudes from the edge of workbench.
S102, the housing assembly 23 dispensed and spindle assemblies 21 are packed into the bushing 14, shell 22 is placed on cylinder
On body component 23 and spindle assemblies 21, pressing plate 16 is placed at the plane of 22 two sides of shell, applies pressure on pressing plate 16, make
14 top end surface of bushing is bonded with bearing inner race lower end surface；
Specifically, housing assembly 23 and spindle assemblies 21 are after the assembly is completed, housing assembly 23 and spindle assemblies 21 are packed into
Bushing 14, wherein bushing plays support and guiding role, can guarantee the cooperation essence between shell and bearing when being pressed shell
Degree avoids bearing and the stuck phenomenon of shell 22 caused by bearing bias, bushing top end surface and bearing inner race lower end face paste
It closes, it is therefore prevented that pressure assembling force when press fitting all acts on retaining ring, damages retaining ring when avoiding press fitting.
S103, continuation apply pressure on pressing plate 16, are bonded 22 lower end surface of shell with keel 13,22 upper hole of shell
Mouth moves to 23 upper surface of housing assembly；
Specifically, wherein housing assembly includes the components such as plunger, cylinder body, valve plate, and pressing plate is placed on shell two sides
At plane, apply downward pressure on pressing plate, pressed to improve the pressure of efficiency the present embodiment of assembly by press machine,
After shell lower end surface is bonded with keel, upper part of the housing aperture moves to housing assembly upper surface.
S104, the mandrel for being oriented to mandrel 15 and cylinder center hole cooperation are positioned, keel 13 is removed, is continued in pressing plate
Apply pressure on 16, until shell 22 is bonded with the upper surface of two side stands 12.
Specifically, after shell lower end surface is bonded with keel, after upper part of the housing aperture moves to housing assembly upper surface,
Since shell finish dimensional becomes smaller, in order to avoid the phenomenon that housing assembly is stuck with shell oral area in assembling process, will be oriented to
Mandrel and housing assembly the centre bore cooperation of mandrel position, and guiding mandrel outer circle is bonded with shell oral area inner hole to play the guiding role,
Keel is pulled outwardly at this time, continues to be pressed shell, housing assembly can be oriented to by the direction of positioning core axle, so as to avoid because of shell
Cylinder body stuck phenomenon caused by body finish dimensional is small.
It is further, described to position the mandrel for being oriented to mandrel and cylinder center hole cooperation in the present embodiment, by keel
It removes, continuation applies pressure on pressing plate, until after shell and two sides cradle fits further include:
S105, pressing plate 16 and guiding mandrel are removed, the shell is fixed on the bracket, assemble motor cylinder component
Valve plate and end-cap assembly 24 in 23.
Specifically, this step is when assembling end-cap assembly, in order to prevent when beating torque to clamping screw shell rotation,
Shell is locked on bracket by bolt in the present embodiment.
The inclined shaft class motor assembly method of the utility model will serve as a contrast the following steps are included: bracket is installed on the workbench
Set is mounted on positioning hole, keel is put into the first locating slot on workbench, by the housing assembly dispensed and main shaft
