Abstract

The invention relates to a measurement tool for keyways, and in particular relates to a keyway width measurement tool. The keyway width measurement tool comprises a dial indicator, a measurement tool body and a standard calibration block, wherein the dial indicator is fixed at the measurement tool by screws; a keyway gauge is arranged at the front end of the measurement body; an elastic groove is arranged in the middle of the measurement body; the extension part of the elastic groove to the keyway gauge forms an elastic groove opening; the measuring head of the dial indicator is pressed in the elastic groove opening; and a groove which fits the keyway gauge is arranged at the standard calibration block and is used for calibration of a standard size of the measurement tool. The keyway width measurement tool is simple and reasonable in structure and convenient to operate and can measure the actual width of keyways accurately.

Description

A kind of width of keyway cubing
Technical field
The present invention relates to the testing tool of keyway, specifically is a kind of width of keyway cubing.
Background technology
In the prior art, width of keyway normally adopts the keyway feeler gauge to detect, and can only judge that whether qualified width of keyway is, and the feeler gauge fixed size is constant, adopts feeler gauge can't accurately detect the developed width value of keyway.
Summary of the invention
Technical matters to be solved by this invention is the deficiency that overcomes prior art, provides a kind of rational in infrastructure, makes simply, and is easy to operate, the width of keyway cubing that detection efficiency is high.
The technical scheme that the present invention solves its technical matters employing is: a kind of width of keyway cubing comprises clock gauge, cubing body, standard proof-reading block; Clock gauge is screwed on the cubing body; Cubing body front end is provided with keyseat gauge; Have elastic groove in the middle of the cubing body, elastic groove forms the elasticity notch to the extension of keyseat gauge; The clock gauge gauge head is pressed in the elasticity notch; Described standard proof-reading block is provided with the groove that cooperates with keyseat gauge, is used for the check and correction of cubing standard size.
The keyseat gauge two sides stud with wimet, can fit tightly keyway to be detected both sides and detect the developed width of keyway.
Width of keyway cubing of the present invention is simple and reasonable, easy to operate, can accurately detect the developed width of keyway.
Description of drawings
Fig. 1 is the structural representation of width of keyway cubing of the present invention;
Fig. 2 is the user mode figure of width of keyway cubing of the present invention;
Among the figure: 1. clock gauge; 2. cubing body; 3. keyseat gauge; 4. elastic groove; 5. standard proof-reading block; 6. groove; 7. workpiece to be detected.
Embodiment
As shown in Figure 1, a kind of width of keyway cubing, it comprises clock gauge 1, cubing body 2, standard proof-reading block 5, clock gauge 1 is screwed on cubing body 2; Cubing body 2 front ends are provided with keyseat gauge 3; Have elastic groove 4 in the middle of the cubing body 2, elastic groove 4 forms the elasticity notch to the extension of keyseat gauge 3; The clock gauge gauge head is pressed in the elasticity notch; Standard proof-reading block 5 is provided with the groove 6 that cooperates with keyseat gauge, is used for the check and correction of cubing standard size.
Keyseat gauge 3 two sides stud with wimet, can fit tightly keyway to be detected both sides and detect the developed width of keyway, make that to detect data more accurate.
As shown in Figure 2; When width of keyway cubing of the present invention is used; When the keyseat gauge 3 of cubing body 2 inserted the keyway of workpiece 7 to be detected, the keyseat gauge elastic deformation of cubing body front end fitted tightly with tested keyway; Just can accurately detect the developed width of keyway, and read concrete width value through clock gauge 1.

Claims (2)
