The invention discloses a lever-type gear mechanism for a micrometer gauge. The gear mechanism comprises a gauge shell and a measuring rod which is vertically arranged, wherein a hollow cavity is formed inside the gauge shell; a lever and a partition are arranged inside the hollow cavity; the measuring rod penetrates through the bottom of the hollow cavity; a sector gear is arranged at one end of the lever, and the other end of the lever is connected with the measuring rod which penetrates through the bottom of the hollow cavity; the sector gear is connected with a gear in a meshing manner; the gear is connected with a pointer; an arm of the lever is propped against a plate spring fixed on an arm of the hollow cavity; the partition sleeves the measuring rod which penetrates through the bottom of the hollow cavity; the measuring rod is further sleeved by a disc; compression springs are arranged between the partition and the disc. The gear mechanism aims to solve the problem that since the conventional micrometer gauge is not provided with an appropriate transmission detecting mechanism, a detector is complex in self structure, cumbersome to operate and low in detecting efficiency.
Description
technical field [0001] The invention relates to detection equipment, in particular to a lever-type gear mechanism for a dial gauge. Background technique [0002] At present, the dial indicator has been widely used in the mechanical field, especially in the various processing links of the mold. It is an essential tool. The dial indicator can measure the accuracy of the geometric shape and mutual position of the workpiece, the length and thickness of the workpiece. , depth, etc., due to different uses, there are many types of dial gauges, with changeable structures, complete functions, and great flexibility. It is not easy or inconvenient to measure the workpiece parts with a micrometer. There are also certain errors in the operation and detection process, and the measurement accuracy is not very high. Using this method is relatively labor-intensive and the detection efficiency is relatively low. However, due to the lack of a suitable transmission detection mechanism in the e...
