There is fixture resigning hole 131, the lower surface of positioning bushing 13 is provided with oil suction tube assembly resigning hole 132, the resigning hole in center
For coniform hole.
Fixture resigning hole 131, during declining for clamping jaw 11, resigning clamping jaw 11, oil suction tube assembly resigning hole 132 is used for
Resigning oil suction tube assembly, oil suction tube assembly resigning hole 132 is designed with rotor end-face inclined-plane or cambered surface coordinates anchor ring, turns for contacting
Sub- tail end face, play positioning, supporting role.
As shown in Figure 1, 2, traditional oil suction tube assembly dismounting mode, the afterbody end ring of rotor 05 is positioned on supporting plane,
Along the radial direction of oil suction tube assembly 06, the external cylindrical surface of oil suction tube assembly 06 is tapped, until oil suction tube assembly 06 and the endoporus of bent axle 07
The face of oil suction tube assembly 06 at interference fit face is deformed, contact interference fit effect, the Automatic-falling of oil suction tube assembly 06.
Due to during oil suction tube assembly afterbody external cylindrical surface is tapped, the different degrees of stress of the parts such as bent axle, rotor,
There is different degrees of influence to its mechanical performance, and then influence compressor pump mechanical performance.
Compressor movement is put upside down on working plate, and upward, freezer compressor oil suction tube assembly detaching equipment is put in be turned motor
On sub- tail end face, now position bushing 13 and fitted with stator faces.Thread 1 is rotated, makes its decline, to two clamping jaws 11
Proper height is reached, oil suction tube assembly afterbody is located exactly in the thread form region of two clamping jaw heads.
Threaded screw rod 8 is rotated, allows two chucks 10 to be drawn close in opposite directions along the track 72 in jig frame 7, in screw drive power
Under effect, chuck 10 drives clamping jaw 11 to clamp oil suction tube assembly afterbody, because oil suction tube assembly is interior form of a hollow pipe structure.Continue to rotate
Threaded screw rod 8, oil suction tube assembly afterbody are embraced nip domain and deformed, kill, and continue to rotate threaded screw rod 8, until threaded screw rod 8
It can not rotate again.Now, because the self-locking action of screw thread and the alternating expression thread form structure of clamping jaw 11, oil suction tube assembly afterbody are complete
Killed completely by clamping jaw 11 entirely.
Now, thread 1 is reversely rotated, under screw thread lever power works use, drives clamping jaw 11 to pull in oil suction tube assembly
Rise, in the uphill process of thread 1, rotate, thrust bearing component 6 can be low by this rotary motion very well
Solution, is eliminated to effect of the torsion to oil suction tube assembly caused by the rotary motion of thread 1.Because oil suction tube assembly is interior blank pipe shape
Structure, when being pressed into bent axle major axis endoporus, the less deformation of mating surface is only relied on, interference fit is produced with bent axle major axis endoporus, its
Caused interaction force is smaller, continues to reversely rotate thread 1, until bent axle length will be pulled it up to screw thread tensile force
The dismounting of axle endoporus, i.e. oil suction tube assembly is completed.
The above is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art,
Without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.
