Including connected cylindrical end and frustum end, a ladder hole is provided with cylindrical end center, the ladder hole is away from frustum end
One end is small stomidium, and the other end is big stomidium, and the frustum end is also equipped with a through hole at center, and the through hole and big stomidium are mutual
Connect, be additionally provided with a strip chute in the cylindrical end, the central axis of the chute and the central axis of shoulder hole are put down
OK, strip chute is connected with shoulder hole；
Also include a measurement bar, one end of the measurement bar through through hole and is stretched into shoulder hole, and it is convex that one is provided with the other end
Platform, the central axis of the boss and the central axis upright of measurement bar, described column handle one end are stretched into strip chute,
And it is threadedly coupled with measurement bar；
The measurement head of the dial gauge offsets through the small stomidium of ladder hole with measurement bar.
Preferably, dial gauge is connected by positioning screw with cylindrical end, and the central axis of positioning screw is surveyed with dial gauge
Measure the central axis upright of head.
Preferably, measurement bar and shoulder hole are interference fits.
Preferably, the lower surface at frustum end and the lower surface of measurement bar are parallel.
Preferably, the cross section of boss is circle.
Preferably, boss edge is provided with rounding.
The present invention is simple in construction, easy to use, solves the measurement problem of internal bore groove critical size well, is led in raising
While the processing of barrel part and efficiency of assembling, the quality of guide part has also well been ensured, has been fuel pump drive mechanism
Good operation provides strong guarantee.

Embodiment
A kind of internal bore groove depth measurement device of the present invention, including tool body 1 and dial gauge 3 and column handle 4, the instrument
Body 1 includes connected cylindrical end and frustum end, being provided with a ladder hole at cylindrical end center, the ladder hole is away from frustum end
One end be small stomidium, the other end is big stomidium, and the frustum end is also equipped with a through hole at center, the through hole and big stomidium phase
It is intercommunicated, a strip chute 6, the central axis of the chute and the central axis of shoulder hole are additionally provided with the cylindrical end
Parallel, strip chute 6 is connected with shoulder hole；
Also include a measurement bar 2, one end of the measurement bar 2 through through hole and is stretched into shoulder hole, and one is provided with the other end
Boss 7, the central axis of the boss 7 and the central axis upright of measurement bar 2, strip is stretched into described one end of column handle 4
In chute 6, and it is threadedly coupled with measurement bar 2；
The measurement head of the dial gauge 3 offsets through the small stomidium of ladder hole with measurement bar 2.
Dial gauge 3 is connected by positioning screw 5 with cylindrical end, and the central axis of positioning screw 5 and the measurement head of dial gauge 3
Central axis upright.Measurement bar 2 and shoulder hole are interference fits.The lower surface at frustum end is parallel with the lower surface of measurement bar 2.
The cross section of boss 7 is circle.The edge of boss 7 is provided with rounding.
This measurement apparatus in for Mechanical Product's Machining and assembling process to internal bore groove depth dimensions when measuring, first
The bottom for the measurement bar 2 being engaged with tool body 1 is put into the small stomidium of tested guide, the lower surface of tool body 1 is with being tested
The small transverse plane of guide contacts with each other, and mobile column handle 4, the lower surface of measurement bar 2 is connect with the bottom hole plane of tested guide
Touch, the reading of dial gauge 3 is now adjusted to zero-bit；Column handle 4 is moved then up, while by the lower plane of tool body 1 tight
