Abstract

The invention provides an improved measuring instrument for measuring the wall thickness of a hollow workpiece, which has a simple structure, convenient manufacture, convenient and practical operation and good practicality. During use, the measuring instrument is not affected by the width of a hollowing part of the hollow workpiece and restricted by the complex degree of an external structure, and has accurate measurement. The improved measuring instrument comprises an instrument shell, and is characterized in that: the instrument shell is provided with a lever-type measuring frame and a measuring rod; and a dial gauge and a measuring head are arranged on the lever-type measuring frame.

Description

A kind of measuring instrument that is used to measure wall thickness of hollow workpiece of improvement
(1) technical field
The present invention relates to the surveying instrument technical field, be specially a kind of measuring instrument that is used to measure wall thickness of hollow workpiece of improvement.
(2) background technology
The measurement of general workpiece mainly is to use vernier caliper, spiral dial gauge or thicknessmeter, and these instruments all block the hollow workpiece wall with its two card base when using, and reading is the wall thickness of hollow workpiece.But when the hollow workpiece cut-out was very narrow, the card base of vernier caliper, spiral dial gauge and diapsida thicknessmeter can not stretch into hollow workpiece, thus energy measurement not; And when hollow workpiece external structure more complicated, need the surveying instrument card base to open the very big outer barrie structure of just walking around and go wall-thickness measurement, so existing surveying instrument can't reach measurement requirement.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of measuring instrument that is used to measure wall thickness of hollow workpiece, it is simple in structure, easy to make, practicality easy and simple to handle, versatility is good, can not be subjected to the restriction of the complexity of the width influence of hollow workpiece cut-out and external structure during use, measure accurately.
Its technical scheme is such, and it comprises watchcase, it is characterized in that: lever measurement bay and sounding rod are installed on the described watchcase, on the described lever measurement bay dial gauge and measuring head are installed.
It is further characterized in that: described lever measurement bay is installed on described watchcase by straight pin; Described lever measurement bay front end is vertically installed with long table bar; Described dial gauge is installed on described long table bar upper end by folder spring and screw; Described measuring head is set in described long table bar inside; Be installed with pressure spring between described long table bar and the described measuring head; Described sounding rod passes through the straight pin horizontal fixed on described watchcase; The described sounding rod front end amount of being equipped with ball center; Described watchcase is provided with set screw; Described set screw level is installed on described watchcase and holds out against described lever measurement bay.
A kind of measuring instrument that is used to measure wall thickness of hollow workpiece of the present invention, it is simple in structure, and it uses the influence that is not subjected to outer workpiece complex structure degree, and is easy to use, the measuring accuracy height.
(4) description of drawings
Fig. 1 is a kind of measuring instrument structural representation that is used to measure wall thickness of hollow workpiece of the present invention.
(5) embodiment
See Fig. 1, the present invention includes watchcase 13, lever measurement bay 12 and sounding rod 7 are installed on the watchcase 13, dial gauge 1 and measuring head 6 are installed on the lever measurement bay 12.Lever measurement bay 12 is installed on watchcase 13 by straight pin 9; Lever measurement bay 12 front ends are vertically installed with long table bar 3; Dial gauge 1 is installed on long table bar 3 upper ends by folder spring 2 and screw 4; Long table bar 3 internal sleeve are equipped with pressure spring 5 and measuring head 6; Pressure spring 5 is installed between long table bar 3 and the measuring head 6; Sounding rod 7 passes through straight pin 15 horizontal fixed on watchcase 13; The sounding rod 7 front end amount of being equipped with ball center 17; Watchcase 13 is provided with set screw 8; Set screw 8 levels are installed on watchcase 13 and hold out against lever measurement bay 12.Among Fig. 1,10 is pressure spring, and it is installed on watchcase 13,14 by straight pin 11 is cap, and 16 is screw.
When the present invention uses, at first adjust set screw 8, make the amount ball center 17 of sounding rod 7 front ends pass through the center line 18 of measuring head, push down the handle portion of lever measurement bay 12 then, make lever measurement bay 12 around straight pin 9 rotations, thereby lift measuring head 6, again calibrated bolck is put between measuring head 6 and the sounding rod 7, unclamp the handle portion of lever measurement bay 12, dial gauge is returned to zero; Then, take off calibrated bolck, press the handle portion of lever measurement bay 12, make lever measurement bay 12 around straight pin 9 rotations, lift measuring head 6 sounding rod 7 is stretched into the hollow object cut-out, unclamp lever measurement bay 12 handles, read the reading of dial gauge, this value is the difference of actual value and theoretical value, theoretical value and dial gauge reading value is subtracted each other promptly draw actual value.
