Description
Technical Field
The utility model relates to a technique in micrometer assembly field specifically is a wide range micrometer parallel adjustment frock.
Background
The conventional 100-inch 200mm wide-range micrometer is assembled by adopting the following process: fixing a parallel clamp on a ruler frame at the position of an anvil hole, and adjusting the position of the anvil through a screw on the parallel clamp to enable the measuring surface of the anvil to be parallel to the measuring surface of a micrometer head screw rod; and after the parallel adjustment is qualified, the anvil in the anvil measuring hole can not be taken out, and only glue can be applied from the other side of the anvil measuring hole, so that the glue slowly permeates into the anvil and is solidified to complete the assembly of the anvil. Due to the fact that glue penetrates unevenly, the position of the measuring anvil is out of place after solidification, parallelism is easy to change, and the qualified rate of the micrometer is low. In addition, the appearance of the surface of the ruler frame is easy to damage in the parallel adjustment process.
In order to solve the above problems existing in the prior art, the utility model discloses come from this.
