Abstract
An auxiliary large-aperture inner hole measuring tool comprises a supporting and positioning plate. The supporting and positioning plate is provided with two hollow rods; a reset spring is arranged in each hollow rod; a push plate is sleeved on the reset springs and is installed on the reset springs by locking nuts; two guide rods are fixed on the push plate; and sliding sleeves are arranged on the guide rods and are sleeved on the hollow rods. The auxiliary large-aperture inner hoe measuring tool structurally eliminates the way of conduction through the guide rods, so that the structure becomes simple, and the height is reduced. As the measurement scope can be adjusted automatically through additionally arranging a connecting rod, the measurement scope is large and flexible. The auxiliary large-aperture inner hoe measurement tool has low cost; both the measuring head of a dial indicator and the measuring head of a measuring rod can be replaced according to the abrasion situations at any time and are general accessories of the measuring tool; the auxiliary measuring tool has the characteristics of light weight and compact structure, is convenient for calibration before measurement and ensures that the measured data is more accurate through leading the supporting and positioning plate at the front end to be aligned with a center point in the measurement process. Therefore, the auxiliary large-aperture inner hole measuring tool integrates the accuracy, the practicability and the flexibility into a whole body.
Description
Technical field
The utility model relates to a kind of survey instrument of heavy caliber endoporus, is specifically related to a kind of heavy caliber hole measuring aid that is used on the conventional internal diameter bore gauge.
Background technology
When super large diameter of bores such as measurement steel part; By heavy caliber endoporus dimensional measurement aid; Can contact the symmetrical steel wall of endoporus fully through the axle center; Easy and conveniently measure hole dimension in the heavy caliber, thereby improve measuring accuracy, solved hole dimension in the heavy caliber that conventional inside meter can't measure.Existing heavy caliber internal diameter bore gauge complex structure, measurement data show through the dial gauge that moves through between guide rod and the measuring head; Be prone to produce the drawback of mistake when calibrating before measuring; And the bore gauge preponderance, the long-time accuracy that influences reading easily of using.
The utility model content
The purpose of the utility model is to reduce error when avoiding the clumsy and calibration of existing bore gauge when measuring the heavy caliber endoporus, and a kind of simple to operate, accuracy of reading, measurement aid that error is little are provided.
In order to address the above problem, the utility model is realized through following method.
A kind of heavy caliber hole measuring aid comprises support positioning plates, and support positioning plates is provided with two hollow stems; Be provided with back-moving spring in the hollow stem; Sheathed push pedal on the back-moving spring, push pedal is installed on the back-moving spring through check nut, fixing two guide poles in the push pedal; Guide pole is provided with sliding sleeve, and sliding sleeve is enclosed within on the hollow stem.
During measurement, dial gauge table body is installed between two sliding sleeves, the measuring head of dial gauge passes support positioning plates, and sounding rod is fixedly in the push pedal.
When calibration, regulate length and reach the scope that to use through the measuring head of sounding rod; Fix through check nut; Generally be adjusted to the numerical value of surveying greater than 0.50mm; On the other hand to touch the bottom be scalable dial gauge to 0 to the measuring head at the movable dial gauge of another hand of subsidiary head place, eliminated original bore gauge calibration clumsiness and the big characteristics of error.
Measuring head through dial gauge during measurement directly obtains measurement data on dial gauge; The data error of avoiding existing bore gauge to obtain through measuring head, centering block, a series of motion of guide rod, data are accurate more and avoid other factors to influence the accuracy of the data of surveying.Remove simple, the weight saving that the mode of conducting through guide rod makes that structure becomes from structure.
The utility model also has following characteristics:
1, measurement range can be regulated through increasing extension bar voluntarily, and not only measurement range is big and flexible;
2, with low cost: the measuring head of dial gauge measuring head and sounding rod all can be changed according to abrasion condition at any time, and all is the general accessory of measurer.
3, this measures aid has characteristics in light weight and that structure is light and handy, the calibration before being convenient for measuring, and the support positioning plates centering adjustment point through front end during measurement makes measurement data more accurate.
Therefore the utility model is the heavy caliber hole measuring aid that integrates accuracy, practicality, dirigibility.
