Universal gage for M value of internal spline

Abstract

The invention relates to the technical field of workpiece measuring tools, in particular to a universal gage for an M value of an internal spline. The universal gage comprises a positioning tool, a measuring head, a fixing body, an oscillating rod, a bottom plate, a fixing rod, a clamping sleeve, a scale rod, a hexagon socket head cap head screw, a micro plane bearing, a locking screw, a home-made screw, a spring, an ejector rod and a dial indicator, wherein one end of the lower part of the fixing body is fixedly connected with the scale rod through the hexagon socket head cap head screw; the home-made screw is rotationally arranged in the middle of the fixing body and is pressed against the spring and the ejector rod through the hexagon socket head cap head screw; one end of the ejector rod is pressed against the oscillating rod; the oscillating rod is connected with the scale rod through the plane bearing; the fixing rod is arranged on the clamping sleeve through the hexagon socket head cap head screw and is sleeved on the scale rod; one side of the lower end of the oscillating rod is provided with the measuring head and one side of the lower end of the fixing rod is provided with the measuring head; and the dial indicator and the measuring head are attached to one end of the oscillating rod through the bottom plate. The universal gage has a simple structure, is convenient to operate and easy to manufacture, and the detection accuracy completely meets the detection requirement of a workpiece; and the gage adopts a calibration method, a product has high consistency, and scrap in batches due to a reading error is avoided.

Description

technical field [0001] The invention belongs to the technical field of workpiece measuring tools, in particular to a universal inspection tool for the M value of an internal spline. technical background [0002] At present, the M value of the internal spline is usually measured by a vernier caliper and a corresponding measuring rod. It is inconvenient to measure, the measuring rod is not easy to position, and the measurement efficiency is greatly reduced. In addition, the contact area between the measuring rod and the product is large during measurement, which increases the measurement error. Contents of the invention [0003] In order to overcome the inconvenient measurement of the existing internal spline M value universal measuring tool, the measuring rod is not easy to locate, and the measurement efficiency is greatly reduced; in addition to the shortage of large contact area between the measuring rod and the product during measurement, the present invention provides a ...
