A measuring instrument is an instrument having a fixed form that is used to reproduce or provide one or more known quantities. Today we will have a deep talk about the specifications and uses of Fully Automatic CNC Machine measuring tools.

one Vernier calipers

Vernier caliper structure; The structure of vernier caliper is mainly composed of ruler body, ruler frame, depth ruler, vernier and upper and lower measuring claw. Fastening the butterfly nail. The piece of the basket, the micro-motion device composed of several parts.

Common measuring ranges are :0 ~ 100mm,0~125mm,0~ 150mm,0~300mm,0 ~ 500mm,0 ~

1000mm,0~1500mm,0~2000mm and so on.

The measurement accuracy range is :0.10mm, 0.05mm, o. 02mm(0.01mm), etc., mechanical manufacturing generally uses a measurement accuracy range of 0.02mm.

Expression: measuring range × measuring accuracy range.

For example, the measurement range is 0~150, and the expression of the measurement accuracy range 0.02 is 0~150 ×0.02.

Vernier calipers are used to measure the inner and outer diameters of workpieces. Length dimensions (width, thickness, height dimensions) depth dimensions and hole spacing, etc.

2. Depth vernier calipers

Depth vernier caliper structure; Its structure is mainly composed of ruler body, ruler frame, fastening screw, vernier, adjusting screw and blade spring.

The common range is generally :0 ~ 100mm,0~ 150mm,0~ 300mm,0~500mm and so on.

The measuring accuracy range is: 0.1mm, 0.05mm, 0.02mm, 0.01mm and so on.

Expression mode; Measuring range x measuring accuracy range.

For example, l, the expression of measuring range 0 ~ 300 and measuring accuracy range 0.02 is 0 ~ 300×0.02.

Depth vernier calipers are mainly used for measuring step and blind holes. Depth of workpiece such as groove.

3. Height vernier caliper

The structure of the height vernier caliper is mainly composed of the ruler body. Microframe, ruler frame, vernier, fastening screw, marking claw, base several parts.

The common range is generally :0 ~ 300, 0 ~ 500mm and so on. The measuring accuracy range is :0.02mm, 0.01mm and so on. The expression is measuring range × measuring accuracy range.

For example, the measurement range is 0 ~ 300, and the expression of the measurement accuracy range 0.02 is 0 ~ 300×0.02.

The measuring work of height vernier caliper is to measure or mark the displacement of the ruler body relative to the base through the marking claw on the ruler frame, which is mainly used to measure the height size, relative position and precision marking of the workpiece.

Note: Height vernier caliper measurements or lines should be performed on the platform.

4. Tooth thickness vernier calipers

Its structure is mainly composed of horizontal main ruler, micro nut, vernier, travel frame, active measuring claw, height ruler, fixed measuring claw, fastening screw, vertical main ruler several parts.

Common range - die: M1-18, M1-26 (modulus) and so on.

Expression mode; A tooth thickness vernier caliper with a modulus of 1 to 26 is represented as M26.

Tooth thickness vernier calipers are used to measure the fixed chord thickness and the indexing circular chord thickness of straight and helical cylindrical gears.

5. Universal Angle ruler

The structure of the universal Angle ruler is mainly composed of the main ruler, the base ruler, the brake, the fan plate, the straight Angle ruler, the straight ruler, the clamping block and the micro-motion device.

Common ranges are generally 0° -320 ° external Angle and 40° -130 ° internal Angle.

Measurement accuracy ranges are 2' and 5'.

Expression: measuring range × accuracy.

For example; The measurement range is 0° ~ 320° and the reading value is 2'. The expression with an allowable error of 2' is: 0° - 320° x 2'.

The purpose of the universal Angle ruler is to measure the workpiece Angle and mark the Angle according to the vernier reading by contact method.

6. Outside micrometer

The structure of the outer diameter micrometer is mainly composed of ruler frame, measuring anvil, measuring microscrew, threaded shaft sleeve, fixed sleeve, differential cylinder, adjusting nut, spring sleeve, gasket, force measuring device, locking purple device and heat insulation device.

The common range of the micrometer has a measuring upper limit of no more than 300mm, which is segmsegmed by 25mm, such as 0~25mm,

25 ~ 50mm,... , 275~300mm, etc. Micrometer with measuring upper limit greater than 300mm to 1000mm, according to 100mm

Segments, such as 300 ~ 400mm, 400 ~ 500mm,......

Measuring accuracy: 0.001 (some micrometers do not have a third ruler. The accuracy is 0.01, the thousandth is the estimate reading).

Expression mode; Measuring range x measuring accuracy range.

For example, the expression for measuring range 0 to 25 and measuring accuracy range 0.01 is 0 to 25×0.01.

The use of external micrometer; Various dimensions, such as length, of IT7-IT12 workpieces can be measured. Outer diameter, thickness, etc.

7. Inside micrometer

The structure of the inner micrometer is mainly composed of a fixed probe! Female, fixed sleeve, locking device, micromeasuring screw, differential simple, movable probe, adjust the measurement. Fittings. Springs, bushings. Measuring rod consists of several parts.

The measuring range is generally :5 ~ 30mm,25 ~ 50mm,50 ~ 75mm,75 ~ 100mm and so on; Plus measuring rod measurement: there are :50 ~ 250mm,50 ~ 600 and so on. The measuring lower limit of the inner diameter micrometer is :50mm, 75mm, 150mm, etc., and the measuring upper limit is up to 5000mm.

Measurement accuracy (index value) :0.01.

Expression mode; Is measuring range x measuring accuracy range.

For example, if the measurement range is 5 to 25 and the measurement accuracy range is 0.01, the expression is 5 to 25x0.01.

The purpose of the inside micrometer: to measure the aperture of the IT10 or lower IT10 workpiece. Slot width, distance between the two ends equal internal dimensions.
