To ensure the performance of modern equipment, parts made with high precision are needed, so no production can do without control and measuring tools.
One of the most popular is a caliper depth gauge - a special type of measuring tools, the main purpose of which is the exact determination of the depth of drilled holes, grooves, grooves and the height of the protrusions. With it, you can perform measurements with maximum accuracy. At the same time, it has a simple design and ease of use. The depth gauge is actively used in such industries as construction, engineering, jewelry and others. It is widely used in the manufacture and processing of products from various materials, when performing turning, milling, locksmith operations.
Design features
The design of the depth gauge is simple, it consists of the following main elements:
p>- measuring rod with divisions,
- frame with support and reading device that moves along the rod,
- clamping screw.
How does the tool work?
The depth gauge is installed on the measured product so that the end of the rod can easily enter the measured area (groove) as far as it will go. There should be no gaps between the end of the rod and the surface of the part, it must fit snugly against it. After that, the frame is lowered, and the bar is fixed. The specialist takes readings from the readout device, and then calculates the depth of the measured groove or groove.
Depth gauges are produced in accordance with the requirements of GOST 162-90. For manufacturing, alloys of increased hardness are used. To measure grooves of complex and narrow shape, special devices can be used, for example, measuring needles.
What types of tools exist?
Depth gauges are classified according to the type of reading device:
- vernier - the reading is carried out on a vernier scale, they are the most common. The measurement process is described above. Measurement accuracy - 0.1 mm.,
- digital - the reading is carried out on an electronic scale. Instruments of this type are easy to use and reduce the possibility of errors during measurement. The principle of operation is similar to vernier instruments. Measurement accuracy - 0.01 mm.,
- micrometric - the reading is carried out using an accurate measuring rod - a micrometer. They allow measurements to thousandths of a mm. The measurement accuracy is 0.02 mm.
The marking applied to the tool characterizes the type, price of divisions, and the measurement range of the tool. An example of marking - ШГ - a tool with a vernier reading device; ShGK - the tool is equipped with a circular scale; ShGC - digital model of the instrument.
Depth gauges are control and measuring instruments, they must be regularly checked and calibrated so that the measurement indicators do not exceed the error limits.
In order for the measurements to be accurate in the process of working with the tool, the following rules must be observed: the air temperature in the room should be in the range from +5 to +25 degrees,
Care of the tool and proper operation will significantly increase its service life .
