It is installed in sleeve, gauge head top pressure is provided with contact in one end of movable post, the other end of movable post, and one end top pressure of spring is in end
Lid, other end top pressure in movable post, for providing an elastic force towards the sleeve other end to movable post.
Preferably, the other end of described sleeve is provided with flange.
Preferably, described end cap is provided with external screw thread, and one end of sleeve lining is provided with female thread, described end cap and sleeve spiral shell
Connect.
Preferably, the other end of sleeve lining is provided with locating part.
Preferably, described locating part is back-up ring.
Compared to existing technology, the beneficial effects of the utility model are：
End cap and sleeve, through threaded, when this central hole depth measuring device needs repairing, end cap are opened,
Therefore convenient maintenance；The part of this central hole depth measuring device is less, easy to assembly, beneficial to replacing part；This depth of center hole
Measuring device small volume and lightweight, is convenient for carrying；Using this central hole depth measuring device, beneficial in process by each rotating shaft
The severity control of centre bore in identical numerical value, using the axle head plane control of each rotating shaft as machining benchmark in lathe axial direction
Same position, thus in lathe batch machining rotating shaft, removing from frequently to knife, improve production efficiency.

Specific embodiment
Below, in conjunction with accompanying drawing and specific embodiment, this utility model is described further：
As depicted in figs. 1 and 2, a kind of central hole depth measuring device, including end cap 1, dial gauge 3, sleeve 4, movable post 5 and
Spring 6, dial gauge 3 includes watchcase body 14 and the gauge head 2 being stretched out by watchcase body 14, and watchcase body 14 is fixed on end cap 1, end
Lid 1 is covered in one end of sleeve 4, and movable post 5 is slidably mounted in sleeve 4, and gauge head 2 top pressure is in one end of movable post 5, movable post
5 other end is provided with contact 8, one end top pressure of spring 6 in end cap 1, other end top pressure in movable post 5, for carrying to movable post 5
For an elastic force towards sleeve 4 other end so that contact 8 in retraction sleeve 4 and stretch out outside sleeve 4 position between cut
Change, this sleeve 4 other end end face is used as measurement datum.
Wherein, dial gauge 3 is fixed on end cap 1 preferably by screw 13；End cap 1 is provided with external screw thread, the inwall 7 of sleeve 4
It is provided with female thread, end cap 1 and sleeve 4 are spirally connected, when needing this central hole depth measuring device is keeped in repair, end cap 1 is opened
?；Movable post 5 is slidably mounted in sleeve 4；The other end of sleeve 4 is provided with flange 9, and the end face of flange 9 is as described measurement
Datum level, has larger contact plane in measurement with workpiece 11, therefore, it is possible to improve certainty of measurement；And the inwall 7 in sleeve 4
It is provided with locating part 10, this locating part 10 is preferably back-up ring, so that without departing from sleeve 4 during movable post 5 slide downward；This centre bore
The part of depth measurer is less, easy to assembly, beneficial to replacing part.
Preferably, when being measured using this central hole depth measuring device, contact 8 enter centre bore 12 and top pressure in
In centre bore 12, drive activity post 5 upward sliding, movable post 5 drives gauge head 2 to move upwards, compresses spring 6, now simultaneously
