Abstract

The utility model relates to a flexibility detection ruler comprising a ruler body and an indicator, wherein the indicator is arranged at one end of the ruler body and the end is provided with an end cover; the ruler body is hollow and is internally provided with a scale lever; two ends of the scale lever protrude out of the ruler body and one end of the scale lever is provided with a zero-setting nut; the zero-setting nut is located at the outer side of the end cover and an end part of the other end of the scale lever is provided with a contact pulley. As the contact pulley in the utility model is detachable, the contact pulley can be independently detached to be replaced after the contact pulley is abraded; and when work pieces with different diameters or greater flexibilities are measured, the scale lever can be replaced to detect.

Description

A kind of amount of deflection detection ruler
Technical field
The utility model belongs to measurer manufacturing technology field, is specifically related to a kind of easy amount of deflection detection ruler.
Background technology
When the processing plug, the plug aligning after the tempering is an one procedure important in the plug production procedure.Measuring when not passing through the bar of turning, because the diameter run-out of workpiece flexibility, surfaceness and workpiece is all bigger, so when using general measurer (like dial gauge etc.) measurement, the loss of measurer is bigger.
Summary of the invention
The utility model provides a kind of amount of deflection detection ruler that can be used for test bar class and pipe fitting linearity for solving the technical matters that exists, and this chi especially can be measured to the bigger workpiece of surfaceness.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of amount of deflection detection ruler, comprise blade and pointer, and pointer is located at blade one end; This end is provided with end cap, and said blade hollow is provided with scale bar in it; The scale bar two ends protrude in blade, are carved with scale on the scale bar shaft, and scale bar one end is provided with the zeroing nut; The zeroing nut is positioned at the end cap outside, and the end of the scale bar other end is provided with the contact pulley.
The utility model can also adopt following technical measures:
Also be provided with a retaining head in the said blade, be provided with light spring between said retaining head and the end cap.
Said blade and scale bar concentric.
Advantage and the good effect that the utlity model has are:
1. because the contact pulley is detachable, therefore after the wearing and tearing of contact pulley, can dismantles the contact pulley separately and change.
2. replaceable scale bar detects again when measuring the bigger workpiece of different-diameter or amount of deflection.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among Fig. 1: 1. scale bar, 2. pointer, 3. blade, 4. contact pulley, 5. fastening bolt and nut,
6. light spring, 7. end cap, 8. zeroing nut, 9. retaining head.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of amount of deflection detection ruler mainly is made up of scale bar 1, pointer 2, blade 3, contact pulley 4 and zeroing nut 8; Blade 3 hollows are provided with a retaining 9 in it, pointer 2 is located at blade 3 one ends; This end is provided with end cap 7, is provided with a light spring 6 between end cap 7 and the retaining 9.Scale bar 1 passes blade 3, blade 3 and scale bar 1 concentric.Scale bar 1 two ends protrude in blade 3, are carved with scale on scale bar 1 shaft, and an end of scale bar 1 is provided with zeroing nut 8, and zeroing nut 8 is positioned at the outside of end cap 7, and the other end of scale bar 1 is equipped with contact pulley 4 through fastening bolt and nut 5.
The principle of work of the utility model is: a need be installed on the utility model on the general magnetic force gauge stand and get final product in use; To contact pulley 4 during measurement and be adjacent to workpiece; Make light spring 6 compress somewhat, when workpiece rotates, cooperate on the scale bar tail end scale and pointer to read the amount of deflection size.
After long-time the use, 4 wearing and tearing of contact pulley may be compared serious, at this moment can dismantle contact pulley 4 separately and change, and replaceable scale bar 1 detects again when measuring the bigger workpiece of different-diameter or amount of deflection.
