Elastic collet 1-2 spreading.
The specific assembling process that a kind of shaft sleeve parts of the invention decompose fixture is as follows:
Spreading elastic collet 1 is manufactured first, in the fabrication process, sizing is tempered after point half end tightening, then by locking screw
Mother 5 is screwed on the external screw thread of spreading elastic collet 1, i.e., locking nut 5 is inserted in spreading elastic clip from 1 lower end of spreading elastic collet
First 1, it is then threaded on the external screw thread of lower half portion 1-1-2 of casing 1-1；The lower half of the screw-in of abutment sleeve 2 casing 1-1 will be adjusted
On the 1-1-2 of part；Conical surface mandrel 4 is assembled in spreading elastic collet 1；By the spiral shell on handle 3 and 1 outer circle of spreading elastic collet
Pit is connected and fixed, and assembly is completed.
As shown in figure 3, the specifically used method that a kind of shaft sleeve parts of the invention decompose fixture is as follows:
First by the contracted diameter end of spreading elastic collet 1 (lower end of spreading elastic collet 1 i.e. shown in fig. 1 or fig. 2,
Such as its contracted diameter is less than Ф 9) it is inserted into the blind hole 6-1 (blind hole aperture be Ф 9) of shaft sleeve parts 6, then rotary cone
Mandrel 4 keeps fixture whole to the mobile (rotation of the arrow direction conical surface mandrel 4 in Fig. 3 of the internal rotating of spreading elastic collet 1
Direction), until the conical surface of elastic collet 1-2 lower end inner wall in the conical surface and spreading elastic collet 1 of 4 lower end cylindrical body of conical surface mandrel
It is in contact, by elastic collet 1-2 multiple in spreading elastic collet 1 gradually spreading, 1 outer diameter of spreading elastic collet and shaft sleeve parts 6
Aperture it is consistent and have gap, spreading elastic collet 1 can rotate in the blind hole 6-1 of shaft sleeve parts 6, elastic collet 1-2's
The step 1-4 of lower end end is located at the outside of the blind hole 6-1 lower end surface of shaft sleeve parts 6, can be stuck in the lower end end of blind hole 6-1
Outside face；Then it is mobile to 6 direction of shaft sleeve parts to make it for rotation adjustment abutment sleeve 2, and makes to adjust 2 lower end of abutment sleeve four
Equally distributed raised step 2-1 is matched with four slot 6-3 on shaft sleeve parts 6, i.e. in raised step 2-1 insertion groove 6-3,
Then it is locked with locking nut 5 by abutment sleeve 2 is adjusted, it is finally whole using 3 rolling clamp of handle and to drawing outside product 7
It is dynamic, drive shaft sleeve parts 6 to rotate from product 7 by four equally distributed raised step 2-1, as shown in Figure 4.Pass through
Shaft sleeve parts 6 had not only been extracted using fixture of the invention, but also have not damaged the sealing ring 6-1 above shaft sleeve parts 6, can also have been protected
Card inner hole of shaft sleeve is not damaged by friction.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
