Preferably, in the self-centering detection rod, the tail of the threaded part on the detection rod is of an outer hexagonal structure.
Preferably, the self-centering detection rod is provided with a striking rod at the end close to the thread, two ends of the striking rod are provided with clamp blocking sheets, and the striking rod is provided with a striking block capable of sliding.
The invention has the following beneficial effects:
1. the utility model discloses a cover external diameter that rises changes and realizes examining location, the clamp of stick tightly, adopts one to examine the stick and can realize the adjustment of same type of bearing frame in the assembling process.
2. The utility model discloses an expansion sleeve external diameter changes, adapts to different dead eye, need not to measure dead eye diameter before the installation.
3. The utility model discloses an it changes to rise the cover external diameter, and the normal size of the cover that rises is little than the dead eye, can easily pack into in the dead eye during the installation.
4. The utility model discloses a beat the body, including beating the utensil pole, beating the utensil piece, beating the utensil separation blade, realize easily removing and examine the stick and rise the cover interlocking.
5. The utility model adopts the special expansion sleeve which is adhered by two materials, one is made of high-hardness metal material, thereby ensuring the precision and the service life of the expansion sleeve; the other is a non-metal elastic material, which ensures the expansion and contraction functions of the expansion sleeve. The expansion sleeve has the advantages of parallel movement, uniform stress and large stroke.

Detailed Description
Example 1
A self-centering dipstick, the structure comprising: examine stick 1, rise set 2, gland nut 4, examine stick 1 and be cylindrical, examine and be equipped with on the stick 1 and examine the circular cone platform coaxial with stick 1, the angle of the circular cone platform outside and rise set 2 inside phase-match, examine the stick 1 and be close to the tip of circular cone platform and be equipped with the screw thread part, gland nut 4 passes through the screw thread and examines stick 1 and be connected.
A transition gasket 3 is arranged between the expansion sleeve 2 and the compression nut 4. The transition washer 3 ensures that the position of the compression nut 4 is outside the bearing hole, ensuring space for the operation of the wrench.
The tail part of the thread part on the detection rod 1 is of an outer hexagonal structure. When the detection rod 1 is installed, an open spanner is adopted for fixing, and the compression nut 4 is conveniently screwed.
The end, close to the thread, of the inspection rod 1 is provided with a punching tool rod 5, two ends of the punching tool rod 5 are provided with clamp blocking pieces 7, and the punching tool rod 5 is provided with a punching tool block 6 capable of sliding. The interlocking function can be generated among the detection rod 1, the expansion sleeve 2 and the bearing seat, and the interlocking is released through the punching tool.
The inner ring of the expansion sleeve 2 is made of elastic material, and the metal material is made into a plurality of metal rings covering the inner ring, and the distances between the plurality of metal rings are equal. The parallel movement, the uniform stress and the large stroke of the expansion sleeve can be realized.
The utility model discloses a working process: the structure and the embodiment of the utility model are shown in figure 1. When the detection rod is installed, the detection rod does not contain a rear punching part. Examine the stick installation and adopt the fixed outer hexagonal structure of examining 1 end of stick of open end spanner, adopt open end spanner to screw up gland nut 4, compress tightly excessive gasket 3, make and examine the stick 1 and rise the production displacement between cover 2 and open the cover 2 that rises, the outside and the dead eye location of cover 2 that rises to the realization is examined the precision fit between stick 1 and dead eye. When the inspection rod is disassembled, the mode is the same as that of the inspection rod, the compression nut 4 is loosened, the punching tool rod 5 and the end part of the inspection rod 1 are fixed, the punching tool block 6 is extended to move the punching tool rod 5 to the position of the punching tool separation blade 7 far away from the inspection rod, the punching tool block 6 is quickly pushed to the other end of the punching tool rod 5, the inspection rod 1 is pushed by inertia to move, and the inspection rod 1 is separated from the expansion sleeve 2.
The utility model discloses a theory of operation is:
the utility model discloses a examine the circular cone platform of stick 1 and rise 2 production displacements of cover, make the cover 2 even expansions that rise, 2 outside and the dead eye contact of cover that rise, through gland nut 4's pretightning force, the adjustment rises the clamp force between cover 2 and dead eye. The examination rod 1 is separated from the expansion sleeve 2 through the kinetic energy of the beating block 6, so that the injury of an operator caused by brute force disassembly is avoided.
