Description
Technical field
The present invention relates to bit gauge fields, concretely relate to one-piece drill bit and measure mating auxiliary tool.
Background technique
Bit gauge is the gauge size for being used to measure the wear-out parts such as drill bit, centralizer in oil and gas well drilling industry
Common tool, it can measure the maximum gauge of drill bit before and after well, centralizer, and comparison obtains drill bit and centralizer in well
Under abrasion condition, for drilling engineer judge whether replace drill assembly provide data support.Use bit gauge measurement process
In, it is inserted at the gauge of the drill bit to be measured, centralizer that are in upright or suspended state, holds bit gauge level with both hands with hand, clockwise
Adjusting rod is stirred, produces bit gauge inner sheet inwardly until being adjacent to place to be measured, the size of the pointer meaning of adjusting rod is at this time
Measured outer diameter.
Bit gauge needs user to maintain it in horizontality in measurement process, otherwise measured outer diameter meeting
With the error except zone of reasonableness, judgement of the engineer to tool, stratum, borehole size is influenced, bit freezing, cutting ferrule are even resulted in
The engineering accidents such as pipe, thus it is whether particularly significant in horizontality in bit gauge measurement process.But existing bit gauge makes
Used time only relies on whether user's range estimation is horizontal, its measurement accuracy is limited；And existing bit gauge is all by stainless steel alloy material
Be made, heavier mass, one hand of user needs to stir adjusting rod, can only another hand be hold by one hand, even more be easy because
It holds unstable and causes measurement error.
Summary of the invention
The purpose of the present invention is to provide one-piece drill bits to measure mating auxiliary tool, solves to use drill bit in the prior art
When rule measurement, manpower needed to hold, be difficult to ensure its horizontal problem, realizes the purpose for improving bit gauge measurement accuracy.
The present invention is achieved through the following technical solutions:
One-piece drill bit measures mating auxiliary tool, including outer ring, inner sheet, handle, and is set to outer ring upper surface
Adjusting rod, size bar, the outer ring lower surface are fixedly connected with the uniformly distributed N number of telescopic rod of annular, wherein N >=3, on the outer ring
Surface is additionally provided with air-bubble level；The air-bubble level is set to by the size bar.
Manual hold is needed when for the measurement of existing bit gauge, it is difficult to ensure the problem of it is horizontal, influences measurement accuracy,
The invention proposes one-piece drill bits to measure mating auxiliary tool, by being fixedly connected with the uniformly distributed N of annular in outer ring lower surface
A telescopic rod, telescopic rod is placed on ground, and N number of telescopic rod is then used as supporting leg to ensure that bit gauge is steadily placed, and is avoided
The situation for the gripping shakiness that bit gauge is likely to occur is held using manpower, then by the way that bubble level is arranged in bit gauge upper surface
Instrument, intuitively, accurately judges whether bit gauge is in horizontality using air-bubble level, surveys to realize and improve bit gauge
The purpose of accuracy of measurement.In use process of the present invention, the adjusting rod is rotated counterclockwise first, the inner sheet is gone in outer ring,
So that latus rectum among bit gauge is in maximum rating, then it is placed in ground or other even curfaces by the support of telescopic rod
On, upright or suspended state drill bit to be measured is put into or is kept from the latus rectum among bit gauge vacantly to sling, makes its maximum
It is located at plane locating for inner sheet at gauge, observes the air-bubble level at this time, and be shown as according to adjustment with air-bubble level
The height of each telescopic rod stirs adjusting rod, makes bit gauge inner sheet clockwise at this time until air-bubble level is shown to horizontality
It produces until being adjacent to place to be measured, the size of the pointer meaning of adjusting rod is measured outer diameter at this time.It should be noted that making
It is also able to achieve the purpose of the present invention with more telescopic rod, only telescopic rod quantity excessively wastes material and adjustment is got up more
Add very complicated, and three or four telescopic rods are that can guarantee to stablize support to bit gauge.
Preferably, the air-bubble level is set to by the size bar.The air-bubble level is set to size bar
Near, it still is able to observe air-bubble level using remaining light when reading size scale convenient for user, it is ensured that read
Numerical value be to be obtained under bit gauge horizontality, further ensure that the precision of measurement.
Preferably, the telescopic rod is electric pushrod.Electric pushrod is common motor driven telescopic rod, eliminates people
Power controls the flexible labour of telescopic rod, and the electric pushrod is controlled by respective motor and control switch respectively, Ji Nenggen
Flexibly, easily the electric pushrod length that adjusts of needs is regulated and controled according to the display of air-bubble level, alleviate manual work,
It is easy to use.
Preferably, the quantity of telescopic rod is three or four.
To sum up, the invention has the following advantages:
1, one-piece drill bit of the present invention measures mating auxiliary tool, uniformly distributed by being fixedly connected with annular in outer ring lower surface
N number of telescopic rod, telescopic rod is placed on ground, then ensures that drill bit is dry steady as supporting leg and places, avoid user
Power holds the situation for the gripping shakiness that bit gauge is likely to occur；
2, one-piece drill bit of the present invention measures mating auxiliary tool, by the way that air-bubble level is arranged in bit gauge upper surface,
Intuitively, accurately judge whether bit gauge is in horizontality using air-bubble level, and be adjusted by telescopic rod, is made
Air-bubble level is shown in horizontality, then carries out the measurement of outside diameter, improves bit gauge measurement accuracy to realize
Purpose.
