The amount of measuring is the abbreviation of the physical scale. It is a device with a fixed form that has a fixed form, a duplication or providing a quantitative value.For example, the size of the weight, the standard battery, the color temperature, the resistor, the block, the signal generator, and the (single or multi -value, multi -value, stranded, or no ruler) meter are all measured.So what are the useful uses of quantity? How do you operate and maintain?
Use classification
Standard
Refers to the amount of measurement or verification standards.Such as blocks, multi -faceted bonding, comparison of surface roughness, etc.
Universal appliance
Also known as universal energy.Generally refers to the uniformity of the uniformly manufactured by the gear factory.Such as straight ruler, tablet, angle block, stalk, etc.
Dedicated appliance
Also known as non -standard 标.Refers to the amount designed and manufactured for detecting a technical parameters of the workpiece.For example, the internal and external grooves, steel wire ropes, and step -distance regulations are measuring appliances that reproduce the amount in a fixed form. The characteristics are as follows. 1. The unit quantity value is directly reproduced.The actual size, if the volume itself has a duplicate unit.2. There are generally no measurement agencies in structure, no indicator or motion components.If the volume block is only a real thing for the number of units.3. Since there is no measurement mechanism, if it does not rely on other measured measuring instruments, the measured value cannot be measured directly.For example, the volume must be equipped with interference instruments and optical sciences.So it is a passive measuring appliance.
Maintenance and operation method
1. Preparation before the use of work:
(1) Before starting the measurement, confirm whether the work volume is zero.(2) Check whether the amount of the work volume is rust, wear or scratch, etc.(3) Clear the edge of the surface of the workpiece, oil, or slag, etc.(4) Wipe clean with fine soft cloth or dust without dust.(5) The records of regular inspection are needed, and then corrected if necessary.(6) Arrange the amount of work and instruments to be used as appropriate positions.(7) Evilly workers should be paved with soft velvet cloth or soft wipe paper on the workbench (such as: optical flat mirror, etc.).
2. When using the amount of work, you should pay attention:
(1) During measurement, contact with the workpiece should be appropriate, not to be inclined. Avoid touching the measurement surface with your hands to protect the amount of work.(2) The measurement force should be appropriate. Excessive measurement pressure will generate measurement errors, and it is easy to damage the amount of work.(3) The method of holding workpieces should be appropriate to avoid inaccurate measurement.(4) Do not measure the workpiece in the rotation to avoid danger.(5) Do not forcibly push the tools into the workpiece or use tiger clamps.(6) Do not knock, throw or discharge the amount of work at will.(7) The use of special measurements should be used in accordance with certain methods and steps.
Third, the maintenance of the work volume:
(1) After use, it should be cleaned.(2) Apply the cleaning of the cleaning of rust oil and store it in the cabinet.(3) Disassembling, adjustment, modification, and assembly shall be implemented by specialized managers and shall not be implemented without authorization.(4) Check whether the performance of the storage workers should be regularly inspected and make a maintenance record.(5) Periodic inspection should be passed, and the verification size is qualified to be used as a basis for continuing or elimination, and a record of comparing maintenance.
