Description
Technical field
It the utility model is related to a kind of amesdial for measuring small stair large aperture, and in particular to suitable for measurement step deep 5
200~800mm of mm dia hole inside dial indicator.
Background technology
Our company is that client produces a kind of machine components, there is a stepped hole, 685 millimeters, precision H6 of diameter, step depth 5
Millimeter；Slide measure, inside micrometer, dial bore gage, internal diameter thousand in the general measurer in existing measurement endoporus aperture divide
Table, internal diameter thousand divide bar, inside mictometer with three probes etc., are not as that measurement accuracy not enough measurement range is not big enough or shield bridge
The reasons such as width dimensions just have 20 millimeters or measuring head diameter is big can not measure；Professional measurer factory measurer customized is looked for need expense up to ten thousand
Member.
Utility model content
In order to solve the above technical problems, the utility model utilizes the waste and old dial bore gage support of factory and new amesdial table
Head, the inside dial indicator in the above-mentioned step aperture of energy direct measurement is transformed into, ensures measurement request, reduction measurer purchase expense to reach
Purpose.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：
A kind of amesdial for measuring small stair large aperture, including adjustable fixed gauge head, locknut, holding rod, U-shaped fastener,
Amesdial head；The adjustable fixed gauge head is replaceable, adjustable length；The holding rod is waste and old dial indicator bracket, and one end is done
Go out the closely-pitched internal thread being consistent with adjustable fixed gauge head screw thread, for fastening the adjustable fixed gauge head, and load onto locknut；It is another
End makes elastic opening and matches somebody with somebody the U-shaped fastener, for fastening the amesdial head.
The amesdial head-tail is special plus adjustment silk and small spring composition, with adjust gauge outfit movement survey thick stick amount of contraction and
Slow down unloaded indicator vibrations, prevent indicator vibration displacement.It is different when fastening position is from normal use during using amesdial head, just
The often special position of installation fastening uses gauge outfit, and what is now fastened is by improved afterbody.
Preferably, adjustable fixed gauge head is from the general inside micrometer gauge head below 5 millimeters of diameter；Amesdial head is also
Gauge head below 5 millimeters of diameter.
The beneficial effects of the utility model：Pass through above-mentioned technical proposal, diameter by being less than 5 millimeters by the utility model
Gauge head is screwed in holding rod, and the other end loads onto the amesdial head that measuring head diameter is also less than 5 millimeters, by adjusting, being locked
Gauge head makes the measurer be of convenient length, by rotating amesdial head dial plate adjustment zero-bit when being demarcated using general micrometer；The measurer system
This is caused less than 100 yuan, it is ensured that the requirement of measurement accuracy, it is easy to use, flexible, mark to convenient.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
It the utility model is related to a kind of amesdial for measuring small stair large aperture, and in particular to suitable for measurement step deep 5
200~800mm of mm dia hole inside dial indicator, to reach the purpose for ensureing measurement request, reducing measurer buying expenses.
The utility model is described in further detail with reference to embodiment and embodiment.
As shown in figure 1, a kind of amesdial for measuring small stair large aperture, including adjustable fixed gauge head 1, locknut 2, holding rod
3rd, U-shaped fastener 4, amesdial first 5.
Specifically used step of the present utility model is as follows：Again as shown in figure 1, making waste and old dial indicator bracket into holding rod 3,
The closely-pitched internal thread being consistent with gauge head screw thread is made in one end, and the general inside micrometer that dress measuring head diameter is less than 5 millimeters is adjustable
Fixed gauge head 1, and locknut 2 is loaded onto, the other end makes elastic opening and matches somebody with somebody U-shaped fastener 4, fastens amesdial first 5；In reality
During use, shake to adjust gauge outfit movement and survey thick stick amount of contraction and slow down unloaded indicator, in the first 5 afterbody spy of amesdial plus adjust
Whole silk 6 and small spring 7 (shown in Fig. 2).
In the present embodiment, because adjustable fixed gauge head 1 is the general inside micrometer gauge head below 5 millimeters of diameter；Thousand points
Gauge outfit 5 is also the gauge head below 5 millimeters of diameter, so can measurement step deep 5 millimeters, diameter 685mmH6 aperture (Fig. 3
It is shown).
The amesdial of this measurement small stair large aperture makes to be of convenient length by adjusting, locking adjustable fixed gauge head, with thousand points
By rotating amesdial head dial plate adjustment zero-bit when chi is demarcated；Holding rod 3 is held, the movable head of amesdial first 5 is introduced into detected
In hole in piece part, apply pressure, make to contract in movable head, adjustable fixed gauge head 1 is also placed in hole, a hand steered steady adjustable fixed survey
First 1, another hand wobble holding rod 3, Central of the parts is looked for, and amesdial first 5 is observed, the minimum value after indicator is stable, as hole
Footpath measured value.
By embodiment of above, this amesdial can reach measurement step deep 5 millimeters, 200~800mm of diameter aperture,
The measurer manufacturing cost is less than 100 yuan；Ensure accuracy of detection requirement and reach the purpose for reducing measurer buying expenses.
