Abstract

In the utility model, a general scale measuring fixed point is connected with a bow-shaped connecting rod with two contacts, and axis lines of the two contacts of the bow-shaped connecting rod are coincided with the axis line of a general scale rod when in connection. When in measuring, the two contacts of the bow-shaped connecting rod are used as fixed measuring points of a simple inner diameter detector, and a measuring rod of a general scale is used as a movable measuring point and used for measuring radial sizes. When in use, the check tool adopts bow-shaped connecting rods with different lengths and is matched with a dedicated inner diameter ring gauge to correct the general scale, and then can detect inner holes, thereby having convenient, rapid and accurate detection.

Description

Large diameter size appliance special for detecting
Affiliated technical field
The utility model relates to the detecting instrument of internal orifice dimension.
Background technology
At present, general large diameter circular hole class part all is to adopt general dial bore gage or clock gauge to measure, also useful micrometer inside caliper is measured, in manufacturing process because the knife bar problem of the cutter of the position of clamping workpiece and processing, general internal diameter scale and micrometer inside caliper because all wanted measurement the center and can't measure.
Summary of the invention
The utility model provides a kind of large diameter size appliance special for detecting, and is not only easy to use, and accurately and reliably.
The technical scheme that its technical matters that solves the utility model adopts is: an arc extension bar is set on general scale, and the fixed point of extension bar and scale is rigidly connected, and utilizes the moving point of measurement of scale itself to measure.
The beneficial effects of the utility model are, use this detector to detect endoporus, and speed is quick, and precision is accurate, can adapt to the detection of the endoporus of the multiple testing environment that can't pass through measuring center.
Description of drawings.
Below in conjunction with accompanying drawing the utility model is further described.
This figure is the simple and easy wiring layout of cubing for this reason.
1. general scales among the figure, 2. arc extension bar
Specific implementation method
As shown in the figure, general scale (1) is measured fixed point and is connect an arc extension bar (2), arc extension bar (2) can get out of the way the center of detecting the footpath, and arc extension bar (2) has two contacts, and (2) two contact axial lines of arc extension bar and general scale (1) measuring staff axial line overlap when connecting.Guarantee that when measuring two contacts of arc extension bar (2) are as the fixedly measuring point of tray (well) diameter detector in simple and easy, and the moving measuring point of the measuring staff of general scale (1) conduct, general scale (1) measuring staff is a radial dimension.In use, as long as select the arc extension bar (2) of obstructed length for use, and be equipped with special-purpose internal diameter ring gauge and proofread and correct general scale (1), promptly internally the hole is detected, and is so easy to detect quick, accurately.

Claims (1)

1. a large diameter size appliance special for detecting is characterized in that: connect the arc extension bar that two contacts and axis and scale measuring staff coaxial cable are arranged on general scale.
