Gear M-value rapid diameter measuring jaw linkage mechanism

Abstract

The invention relates to a gear M-value rapid diameter measuring jaw linkage mechanism which is characterized by comprising a base plate, wherein a clamp support is installed at one end of the base plate and is provided with a clamp; a first hole of a first sliding block is internally provided with a summation and difference rod; the first sliding block is provided with a first sliding groove installation moving measuring rod device; a first pressing spring fixed seat is provided with a first spring device; a second guide rail is slidingly connected with a second sliding block; the second sliding block is provided with a second sliding groove installation fixed measuring rod device; second pressing spring fixed seats are installed on the base plate; a second spring device is arranged between the second pressing spring fixed seats; the second sliding block is threadedly connected with a clipping body; the clipping body is provided with a measuring device; and a connecting rod device is installed at the middle of the base plate. The gear M-value rapid diameter measuring jaw linkage mechanism provided by the invention is simple to operate, and is intuitive in reading, data is accurate, and the situation that the matched measurement of a clipping ruler and a measuring ball causes error easily is prevented; and the manufacturing cost is low, and the enterprise production operation cost can be lowered.

Description

technical field [0001] The invention relates to a mechanism for fast claw-measuring linkage measurement, in particular to a gear M-value fast-diameter claw linkage mechanism, which belongs to the technical field of measurement and inspection devices. Background technique [0002] During the manufacturing process of involute gears, the measurement of various parameters of the gears is an important task. At present, it is often used to measure the diameter of the cross ball (rod), that is, the M value of the gear, to detect the radial processing size of the gear tooth online. The methods for measuring the M value of the involute gear are: First, use a three-coordinate measuring instrument to accurately measure the workpiece , but its operation is complicated, the price is high, and it is difficult to popularize and use it in the production site; the second is to use the measuring ball and the caliper to measure, which is prone to human error during measurement, poor repeatabil...
