Description

The method of determining the volume of hollow products by filling the test cavity 1 of the cavity with the medium and settlement of the volume. When using this method to determine the volume, for example, of the combustion chambers of the heads of the PLI pdrov DZ.Iatel, oil is used as the medium for firing chambers). Camel-cropainia is tightly closed with a n;) shining n.tappppo; equipped with a graduated glass pipe. Then an oil is poured through the glass p) -1st tube in Kame1), the amount of which is measured in advance by a beaker. About the Depot 10m chamber volume is judged by the setting of the 15 rpaxUynpoaaiHiou tube level mas. And.

This method; shreda.: 1e1P volume hollow products.; Mon, panrimer chambers of erapi. has a number of drawbacks. When the oil is poured in, air bubbles form, the elimination of which takes about 11–11 times, each camera is measured separately, after each measurement it is necessary to drain the oil and wash the product, the measurement accuracy is insufficient and unstable.

In the described method of listing; The deficiencies are eliminated by the use of balls as the working medium for the recording of the intended cavity, and the measuring device ensures 1 time; 1, the measurement of all the combustion chambers of the engine block cylinder head.

ia of FIG. 1 shows a drawing of a pa diagram of the device, the osutstvitsii of the described method (side view); on srig. 2- is a section along AA of FIG. I.

The drum Y can be rotated pa, on the pins 2, fixed 13 pillars 3. and fastened in the required position with a finger 4. In two opposite,: | aerial steps ax 5 drums / turnips; transparent tubes 7, irezhity mp in the middle. Niriki 8 having a diameter ne of more than 2 mm are drawn into the tubes. The balls fill the poles of the inspected chambers 9, the measuring 6 n part of the tubes 7 to the level shown by the peak 10. The stopper // protects the drum / from the idle turn.

On a scale of 10, risks corresponding to the most

the smallest volumes of combustion chambers. Scratching is done with reference 1-tin. One of the reference heads is mounted on the installation pins 12 on the upper wall of the drum 1 and secured with the clamping clip 13.

After releasing the locking pin 4, rotate the drum / by 180 ° and the EU ishriks fall asleep all the craters 6 so that the 1x level is on the same straight line, but with which the risk is applied on 1 nkalah K).

The second reference knob is also mounted on the upper wall 5 of the drum /, which is then turned 180 and the risks are applied but the ypoBino balls are set on the second scale. In some places at the floor: on the heads, on the lines of 10, the risks corresponding to the maximum or minimum volume of the combustion chambers of the engines are applied.

After applying scratches on the scales 10, the device is ready for operation. The tested head 6, the engine cylinder head is attached to the upper wall 5 of the drum /. Then baraba; turn on 180. Balls, peresyp, with Volume of combustion chambers1 and. co. Then the cycle is repeated.

Subject invention

Claims (2)

1. A method for determining the volume of hollow articles, such as combustion chambers of the heads of engine cylinders, by filling the .iocTii with a working medium and then measuring the volume of this medium so that as a working medium irimen Yut balls. 2. A device for carrying out the method according to claim 25, wherein it is made in the form of a rotary drum, provided with measuring funnels oppositely arranged and pairwise connected by means of transparent tubes, the large bases of which are intended to be mounted on them are checked chambers filled together with funnels with a measured portion of balls being poured into opposite chambers and funnels when the drum is turned.
