The invention discloses a radial swing hole shrinking device used for a lever micrometer and a hole shrinking method of the radial swing hole shrinking device. The device comprises a pair of hole shrinking blocks, and a pair of adjusting screws, wherein one end of each adjusting screw is connected with each hole shrinking block in a one-to-one corresponding manner, and the other end of the adjusting screw is arranged in each of two sides of a frame at a movable measuring anvil end of the lever micrometer. According to the radial swing hole shrinking device used for the lever micrometer and the hole shrinking method of the radial swing hole shrinking device provided by the invention, the hole shrinking device is simple in structure, and easy and convenient to operate, by utilizing the combined configuration of the adjustable adjusting screws and the hole shrinking blocks with cross sections in the shape of circular arc belts, the problem of the radial swing of a movable measuring anvil in the using process caused by the enlargement of a movable measuring anvil hole due to the wear of the movable measuring anvil after long-term use is effectively solved. The repeated repair for the lever micrometer is facilitated, so that the precision of the repaired lever micrometer meets the precision standards of the lever micrometer in the using process, and the service life of the lever micrometer is prolonged after repair.
Description
technical field [0001] The invention relates to a maintenance device for a lever micrometer, in particular to a radial swing shrinkage device and a shrinkage method for a lever micrometer. Background technique [0002] Lever micrometer is a universal length precision measuring tool that uses the principle of leverage and an indicator to read the distance between the two measuring surfaces on the curved movable anvil end frame. During the use of the lever micrometer, the movable anvil often goes in and out of the movable anvil end frame, which causes the movable anvil hole in the movable anvil end frame to be worn for a long time, thus affecting the use accuracy of the lever micrometer , Even cause the lever micrometer to be scrapped and cannot be used. The maintenance methods for this situation in the prior art include: impact shrinkage cavity method, squeeze hole method, drill sleeve method and chrome plating method. [0003] Among them, the impact shrinkage method: it is...
