OPERATING INSTRUCTIONS FOR INTERNAL THREAD COMPARATOR

內(nèi)螺紋指示規(guī)操作指南

MOUNTING GAGE SEGMENTS

固定指示規(guī)螺紋測頭

Clean mounting surface on frame and segments. Locating surfaces must be free of any lint or dirt to avoid incorrect seating of segments. Attach segments to frame with mounting screws. Segments are interchangeable top to bottom. Depress operating lever to be sure bottoms of segments match face to face (not cocked)

擦試干凈框架和螺紋測頭的表面表面不得有任何線頭或者污垢，避免螺紋測頭的不正確就位。用緊固螺絲把螺紋測頭裝上。螺紋測頭從上到下的順序進行更換。按下操作手柄，確保底部的螺紋測頭與被測螺紋面到面貼合（不要翹起）。

SETTING THE ITC THREAD COMPARATOR

ITC螺紋指示規(guī)的設(shè)定

The comparator is set with a single master ring gage.To engage the master ring gage, depress the operating lever at the back of the comparator and place the master ring gage on the segments. Gently rock the master ring gage to ensure that it is seated correctly. 這個指示規(guī)通過一個環(huán)規(guī)標(biāo)準(zhǔn)件進行設(shè)定。為了與標(biāo)準(zhǔn)環(huán)規(guī)吻合，按下操作手柄，把環(huán)規(guī)標(biāo)準(zhǔn)件放在螺紋測頭上。輕輕搖擺環(huán)規(guī)標(biāo)準(zhǔn)件到正確的放置位置。

MOUNTING THE ELECTRONIC INDICATOR

固定數(shù)顯讀數(shù)表

The digital electronic indicator is held in place by a clamp nut. Preload the indicator to .250” on the digital readout. Lock the indicator with the clamp nut. Push the clear button or zero button to zero the indicator. Rock the master ring gage slightly to check seating and push the zero or clear button again to ensure ITC is set.預(yù)置讀數(shù)到0.25英寸。.數(shù)顯讀數(shù)表通過一個夾持螺母來進行固定。通過夾持螺母固定數(shù)顯表按復(fù)位鍵或者零位鍵讓數(shù)顯表歸零。輕輕搖動環(huán)規(guī)標(biāo)準(zhǔn)件檢查正確放置，再次按零位鍵或者復(fù)位鍵確保指示規(guī)已經(jīng)設(shè)定好。

Depress operating lever and remove master ring gage. If SPC operation is required consult with indicator manual for data management and programing. 按下操作手柄，取出環(huán)規(guī)標(biāo)準(zhǔn)件。如果需要SPC操作，請查閱讀數(shù)表手冊以獲取數(shù)據(jù)管理和編程。

MOUNTING DIAL INDICATOR

固定指針表

The dial indicator is held in place by a clamp nut. Preload the indicator at least one full revolution and adjust the indicator to read zero. Lock the indicator in place with the clamp nut. Rock the master ring very slightly to check seating. Loosen the bezel clamp on the indicator face and locate indicator pointer at zero. Adjust indicator tolerance hands (if available) to tolerance limits. Tighten the bezel lock screw.

指針表通過夾持螺母進行放置。預(yù)置至少一次全量程和調(diào)整到讀數(shù)零位。通過夾持螺母瑣緊指針表.輕輕搖擺環(huán)規(guī)標(biāo)準(zhǔn)件以檢查放置位置。 松開指示器表面上的擋板夾，將指示器指針定位在零位。將指示器公差指針（如果可用）調(diào)整到公差限值。擰緊擋板瑣緊螺釘。

CAUTION

提示

DO NOT ROTATE THE MASTER RING GAGE OR THE PART ON THE SEGMENTS AS THIS COULD CAUSE DAMAGE AND WEAR TO THE GAGE AND OR SEGMENTS.

環(huán)規(guī)標(biāo)準(zhǔn)件或者工件放置在指示規(guī)的螺紋測頭上后，不要旋轉(zhuǎn)，因為這樣會導(dǎo)致指示規(guī)的損壞和測頭的磨損。

Erroneous readings may result from rotating the gage or the part due to the helical pull of the thread path. After placing the master ring or the part on the segments they should be rocked slightly to ensure that they are seated properly. If readings at multiple locations are required the operating lever should be depressed to remove the gaging pressure and relocate the part and then release operating lever to read size.

由于螺紋路徑的螺旋拉力，旋轉(zhuǎn)量規(guī)或工件可能會導(dǎo)致讀數(shù)錯誤。將環(huán)規(guī)標(biāo)準(zhǔn)件或工件放置在螺紋測頭上后，應(yīng)輕輕搖動，以確保其正確就位。如果需要在多個位置讀取讀數(shù)，應(yīng)按下操作手柄以消除測量壓力并重新定位工件，然后松開操作手柄以讀取尺寸。

1. Base w/adapter – One base is applicable to all frames

底座：適用所有的尺寸框架

2. Segments – Functional segments or single element pitch diameters segments to check the maximum or minimum limits of size.

螺紋測頭：作用中徑或單一中徑的螺紋測頭，測量或者最小的尺寸極限。

3. Gage Frame – 3 gage frames are available from .189 up to 8.00 inches in diameter

指示規(guī)框架：有3種框架可選，測量直徑尺寸從0.189英寸到8英寸。

4. Indicators – Digital electronic indicators w/output or AGD dial indicators w/.0001” graduations and adjustable tolerance hands

讀數(shù)表：數(shù)顯表，帶輸出，或者指針表。

5. Indicator Clamp Nut – Supplied with frame

夾持螺母

6. Handle – For hａnd held applications

操作手柄

Master Set Ring Gages are supplied with a functional diameter value and pitch diameter value. The functional diameter is the actual measured pitch diameter of a thread adjusted by the cumulative effects of lead error and angle error, which is always added to external threads and subtracted from internal threads. The pitch diameter is the theoretical diametrical plane which passes through a thread at the point where the width of the thread tooth and groove are equal.

環(huán)規(guī)標(biāo)準(zhǔn)件配有功能直徑值和中徑值。功能直徑為通過導(dǎo)程誤差和角度誤差的累積效應(yīng)而調(diào)整的螺紋實際測量中徑值，它總是添加到外螺紋，從內(nèi)螺紋中減去。中徑是一個理論直徑圓柱面，是通過螺紋軸向截面內(nèi)牙型上的溝槽和凸起寬度相等處的假象圓柱的直徑。
