Description of the drawings
Fig. 1 is the structure diagram of the utility model medium-length hole detection self-centering supporting mechanism.
Specific embodiment
It elaborates below with reference to example embodiment to technical solutions of the utility model.However, example embodiment
It can implement in a variety of forms, and be not understood as limited to embodiment set forth herein；On the contrary, provide these embodiments
So that the utility model is more comprehensively and completely, and the design of example embodiment is comprehensively communicated to those skilled in the art
Member.
As shown in Figure 1, it is the structure diagram of the utility model medium-length hole detection self-centering supporting mechanism.
The structure of deep hole detection self-centering supporting mechanism, is used to implement the cross section profile of deep hole pipe and inner surface geometry
Parameter, which is realized, to be measured, and ensures the relative position of sensor and measured hole in actually detected process, structure includes：Supporter
1st, the first locking nut 2, elastomeric pad 3, spring 4, idler wheel 5, support claw 6, rack 7, the second locking nut 8, holding screw 9.
Axial bore room is provided in supporter 1, axial bore room is provided with partition ring 11, and partition ring 11 divides inner cavity chamber
For spring chamber 11, rack chamber 12, spring chamber 11, being open for rack chamber 12 are located at the both ends of supporter 1, and spring 4 is pacified
Mounted in spring chamber 11, rack 7 is mounted on rack chamber 12.
One end of rack 7 passes through partition ring 11, spring 4, is equipped with the first locking nut 2 in end thread, utilizes first
Spring 4 is fixed on rack 7 by locking nut 2, and elastomeric pad 3 is equipped on the rack 7 of 2 inside of the first locking nut；Rack 7
Another end the second locking nut 8 is installed, be provided with locating piece 71 on the rack 7 of 8 inside of the second locking nut, position
Block 71 is against in inner cavity chamber, to be shaken when preventing rack 7 from moving axially.
In order to further limit the accuracy that rack 7 moves axially, on the second locking nut 8 being provided with screw thread leads to
Hole, is provided with screw-threaded counterbore on rack 7, and holding screw 9 is mounted on tapped through hole, in screw-threaded counterbore, passes through the second locking nut
8th, holding screw 9 limits the displacement distance of rack 7, and then adjusts the opening angle of support claw 6.
Supporter 1 is provided with support claw opening in both sides, and support claw 6 is connected to support claw by support claw fixed rotating shaft and opens
At mouthful.Two support claws 6 are in the same plane.One end of support claw 6 is engaged with rack 7 by tooth form, and idler wheel 5 is installed
In another end of support claw 6.When support claw 6 is around the rotation of support claw fixed rotating shaft, band carry-over bar 7 is sliding in inner cavity chamber or so
