Domestic concentricity tester

Domestic concentricity measuring instrument for use Scope: This instrument is suitable for stepped shafts, bushings, bushings and other parts have a measuring concentricity requirements. The main purposes: 1, shaft roundness, concentricity, circular runout, poor precision measuring section 2, the outer shaft and the inner circle, while precision measurement parameters, 3, while multi-shaft parts precision measurement parameters ; 4, rapid measurement, face-off difference, the inner circle and outer circle can be measured simultaneously. Features: 1, the standard accuracy and precision 0.005mm 0.002mm; 2, fast measurements save time; 3, easy operation, versatility; 4, light and easy to move, easy maintenance; 5, less demanding operating environment; 6, based on the special nature of customized parts. Concentricity Tester Model: Select concentricity gauge need to confirm three parts: standard accuracy and precision; work rotation axis; scale specifications and other accessories (scale bracket, standard lever table stand, table stand side lever, rail end brackets, etc.). Operating Instructions: Place the instrument is placed in a dry, clean environment, not directly exposed to sunlight or humid place, avoiding high temperature and severe vibration. Coaxial measuring instrument is a precision instrument, in transport and movement, should be handled with care to avoid shocks and collisions. In order not to affect the accuracy of the instrument, you should use a clean, soft cloth or cotton wool dipped in pure alcohol or a special detergent "job rotation axis" and "guide shaft" to avoid directly touching and wiping. Regular instrument to prevent rust, cleaning and maintenance work to prevent acidic (corrosive) and other substances in contact surface of the instrument. The use of the instrument in a horizontal position to prevent axial movement of the workpiece during measurement. Concentricity tester Usage: 1, according to the workpiece size adjustment "pressure roller" height, "press round" at a suitable pressure can suppress the workpiece. 2, through the "operating handle" rising "press round", the workpiece is placed on the "job rotation axis", and then "press round" homing. 3, adjust the "table frame" in height, and move, so indicator (dial indicator) probe contacts the workpiece surface, adjust the dial indicator to zero. 4, adjust the "leveraged table" probe to the appropriate position of the workpiece, and make contact with the workpiece surface, adjust the dial indicator to zero. 5. Turn the handwheel, according to the actual situation of fine tuning meter, complete reading. Maintenance and repair of all parts should be kept clean, if fine dust that can be used a blower to remove, if any oil or fingerprints, use a cotton wipe gently. Coaxial measuring instrument is a precision instrument, prohibit disassemble, in order to prevent or reduce the measurement accuracy of the instrument is damaged. Coaxial measuring system with a dust cover is not in use, and to avoid the dust; coated with anti-rust oil and stored in a dry place to prevent rusting. To maintain concentricity gauge performance, we recommend regular inspection Troubleshooting Problem Cause when the workpiece axially movable table 1. Measurement table level adjustment rough workpiece surface tapering replace the workpiece probe pressure too much work to fine-tune the rotational axis of the probe have dust or foreign matter to clean the rotating working shaft 2. Rotate the operating shaft rotation is not flexible belt round a foreign body stuck cleaning belt round the workpiece surface glue or magnetic surface cleaners or replace measuring the workpiece 3. The stent difficult to move the guide shaft foreign objects or dust, clean the guide shaft guide shaft rusting rustproof regularly checked and add anti-rust oil spray screw thread trimming 4 trim failure damaged Replace trimmer screw guide shaft rusting rustproof periodic inspection and add 5 meter needle rust oil spray shaking too large workpiece surface tapering or a foreign body or replace the workpiece surface cleaners can move the probe clamp screw is loose or damaged screw fastening screws or replace worn probe Replace the probe instrument damage replace the instrument at the same time my company sales agents and Japan Level FSK long, 100 * 02, the sensitivity of 0.02 seconds per meter four characteristics: accuracy up to +/- 1.0 bubble bottom quintile V- groove and the V- groove parallelism within 1.5mm of the flatness of the bottom foot level are within 0.005mm accuracy of the V- groove also between 1.0 bubble quintile a 90 degree angle of precision within 0.01mm, the bubbles reach the standard of Japan JIS Level-based test machine mounting surface or plate is level, and detect the inclination direction and angle of the size of the measuring instrument, its shape system with high-grade steel material manufacture mountings, after precision machining, its frame housing base must be flat, the central seat surface mount There are longitudinal oval-shaped curved glass, but also in the left lateral additional small horizontal glass tube filled with pipe ether or alcohol, and left a small bubble, it is always in the tube at the highest point. At both ends of the scale division of the bubbles on the glass tube. Typically, the factory-installed machines, used bubble level sensitivity of 0.01mm / m, 0.02mm / m, 0.04mm / m, 0.05mm / m, 0.1mm / m, 0.3mm / m and 0.4mm / m and other specifications, instrument that is placed on the horizontal length of 1 m straight edge or tablet, when one end point sensitivity indicates the size differences, such as the sensitivity of 0.01 mm / m, that is, represents the straight or flat end points are 0.01 mm The level difference (difference between end points equivalent to 2 seconds), when the length of 1 m has h mm height difference, the bubble will be a difference in scale. Bubble level principle is to use the bubbles in the glass tube, the bubbles can be kept at the highest position characteristics for a given angle, and purports to move a large amount of bubbles (so-called good sensitivity), the need to increase the radius of curvature (R) can. If the level meter distance per division and a sensitivity of 2 mm and 0.01 mm / m, the two end points of 1 m quite a difference of 2 seconds. That is the bubble tube radius of 206.185 meters, means within the framework of the different sensitivity that is different radii, while not directly related to the length of the frame. Use a level should first check, the first level on the plate, read the scale size of the bubble, and then placed on the same level meter inverted position, and then read the size of its scale, if the reading is the same, that represents a horizontal instrument base and bubble tubes each other Relations between the right. Otherwise, the required fine-tuning adjustment screw until the same readings, available for measurements. To check the size of the known angle spirit level precision sine bar and the amount of available blocks. At the same time, we want to measure the tilt angle but also with a large sine bar and spirit level used together. The new instrument as a traditional bubble level Tilt alternatives, more applications in road engineering, mechanical measurement, construction, industrial platforms, oil exploration, military, marine, and other needs under gravity reference frame angle or horizontal situation. According to classified material, a level, a level can be divided into plastic, glass spirit level. Low levels of precision plastic instrument, glass spirit level is relatively high accuracy.
