Abstract
The utility model discloses a device for measuring the length at the narrow end of a stepped shaft, which comprises a base. A dial indicator is arranged on the base; a reference block is also arranged on the base and is provided with a through hole through which a rod to be measured passes in and out; and the measuring rod of the dial indicator and the axis of the through hole are positioned on the same straight line. When the device is in measurement, the stepped shaft extends in the through hole, and the length of the narrow end of the stepped shaft can be measured by the dial indicator. The device has the advantages of convenience in measurement, accuracy in measurement and the like.
Description
Technical field
The utility model relates to a kind of measurement mechanism of multidiameter.
Background technology
Multidiameter is exactly to have a narrow end, a wide end as its name suggests, and the axle of step is arranged between narrow end and the wide end.At present, when measuring the narrow end of multidiameter, common way is directly to measure with vernier caliper or other ruler.Adopt the comparatively inconvenience of measurement of this method, more main is that slide calliper rule are difficult for just snapping into two ends during measurement, thereby cause measurement inaccurate.
Summary of the invention
The purpose of this utility model provides a kind of narrow end length-measuring appliance of multidiameter, uses this device can measure the length of the narrow end of multidiameter easily.
For realizing this purpose, the utility model is solved by following technical proposals:
A kind of multidiameter measured material comprises base, and described base is provided with dial gauge, also is provided with reference block on the described base, and reference block is provided with the through hole that is used to treat the measuring staff turnover, and the sounding rod of described dial gauge and the axis of through hole are on same straight line.
In the technique scheme, described reference block is arranged on the base by bolt.
In the technique scheme, described dial gauge is installed on the base by fixed block.
In the technique scheme, described fixed block is by being bolted on the base.
In the technique scheme, be respectively arranged with threaded hole on the diapire around the described base, twist in the threaded hole and be provided with support column.
The utility model compared with prior art has following beneficial effect:
When the utility model is measured, only need multidiameter is stretched into through hole, just can measure the length of the narrow end of multidiameter, have and measure conveniently, measure advantages such as accurate by dial gauge.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view among Fig. 1.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1～Fig. 2, a kind of narrow end length-measuring appliance of multidiameter, comprise base 1, described base 1 is a rectangular parallelepiped, and four jiaos of described rectangular parallelepiped are respectively arranged with threaded hole 10, interior respectively the twisting of described these four threaded holes 10 is provided with support column 9, when like this base 1 being placed worktable, can regulate the degree of depth that support column 9 is screwed into threaded hole 10, thereby make base 1 smooth being placed on the worktable, the height of base 1 and the height of the suitable operation of operating personnel are complementary, are convenient to operation.
Described base 1 top is provided with fixed block 5, and described fixed block 5 is a rectangular parallelepiped, and this fixed block 5 also is provided with threaded hole, twist in the threaded hole and be provided with bolt, fixed block 5 is installed on the base 1 by bolt, and described fixed block 5 is provided with the dial gauge 7 of horizontal placement, and the surface of this dial gauge 7 up.With fixed block 5 by bolt be arranged on be convenient on the base 1 dismounting.
The top of described base 1 is provided with reference block 3 near the edge, and reference block 3 is provided with the through hole 30 that is used to treat the measuring staff turnover, and the sounding rod 70 of described dial gauge 7 and the axis of through hole 30 are parallel or during at same straight line.When not surveying, the end of the sounding rod 70 of dial gauge 7 just leans on the sidewall of reference block 3.
During measurement, multidiameter 11 to be measured is stretched in the through hole 30, the end of the narrow end 110 of multidiameter 11 to be measured leans the end of the sounding rod 70 of dial gauge 7, and the narrow end 110 of multidiameter 11 to be measured and the step that wide end 112 junctions form are leaned on the sidewall of reference block 3, this moment, the reading with dial gauge 7 added that the thickness of reference block 3 is the length of multidiameter 11 narrow ends 110 to be measured.So just can measure the length of multidiameter 11 narrow ends 110 very easily, and measure accurately.
