Abstract
The invention provides a diameter measurement device which comprises a rotation disc. A crescent groove for containing a circular workpiece to be measured and an annular dividing ruler arranged along an edge of the groove are formed on the rotation disc. The dividing ruler is used for indicating the diameter of the circular workpiece to be measured when the circular workpiece to be measured is clamped in the groove. Therefore, a user only need to place the circular workpiece to be measured in the groove, then rotates the rotation disc until the circular workpiece to be measured is clamped in the groove, and reads the diameter of the circular workpiece to be measured from the dividing ruler. The diameter measurement device is high in efficiency.

Embodiment
See also Fig. 1-3, the diameter measuring device 10 of first embodiment of the invention comprises a rotating disk 100.This rotating disk 100 is formed with the crescent shaped groove 102 and the ring-type rule 104 that is provided with along the edge of this groove 102 that are used to accommodate a round piece 20 to be measured.This rule 104 is used for when this round piece 20 to be measured is stuck in this groove 102, indicating the diameter of this round piece 20 to be measured.
So, only need and to put into this groove 102 by round piece 20 to be measured, rotate this rotating disk 100 then and be stuck in this groove 102, just can read the diameter of this round piece 20 to be measured from this rule 104 until this round piece 20 to be measured.
Particularly, this rotating disk 100 comprises a scale face 106.This groove 102 and this rule 104 are formed on this scale face 106.
This groove 102 is surrounded by a crescent bottom surface 108, an excircle side 110 and an inner periphery side 112 jointly.Vertically extend from this bottom surface 108 this excircle side 110 and this inner periphery side 112.The diameter of this inner periphery side 112 is greater than the diameter of this excircle side 110.This inner periphery side 112 is around this excircle side 110.The outer circumference side of the center axis 110
deviate from the inner circumference side of the central axis 112
.
In this embodiment, this rule 104 is provided with near also centering on this inner periphery side 112, and comprises a plurality of pointer scales 114.Each pointer scale 114 is through the following steps setting: a diameter and the corresponding round piece of this pointer scale 114 (for example 12mm) (figure does not show that it is the eyeglass of 12mm that a diameter for example is provided) are provided; This standard circular workpiece put into this groove 102 and rotate this rotating disk 100 be stuck in this groove 102 until this standard circular workpiece; And this pointer scale 114 (for example 12mm) is pointed to this standard circular workpiece contacts (tangent) with this inner periphery side 112 position be provided with.Be appreciated that; This standard circular workpiece can be stuck in this groove 102 two ends respectively; Therefore, this pointer scale chi 104 in other words these a plurality of pointer scales 114 be symmetrical set about the common line of symmetry
of this excircle side 110 and this inner periphery side 112.
This rotating disk 100 is a round turntable, this diameter measuring device 10 comprise one from this rotating disk 100 and this scale face 106 opposing sides along perpendicular to these scale face 106 extended rotating shafts 200.In order to make this round piece 20 to be measured when this rotating disk 100 is rotated in this rotating shaft 200, receive bigger centrifugal force, this rotating shaft 200 is provided with along the central shaft
of this inner periphery side 112.
In this embodiment, this diameter measuring device 10 also comprises a supporting plate 300 (can be the part of working machine platform).This supporting plate 300 offers a through hole 302 that matees with this rotating shaft 200.This rotating shaft 200 is inserted in this through hole 302.So, this rotating disk 100 can be carried on this supporting plate 300 and with respect to this supporting plate 300 and rotate.
Preferably, this diameter measuring device 10 also comprises a bearing 400.This bearing 400 also is arranged in this through hole 302.This rotating shaft 200 is connected with this supporting plate 300 through this bearing 400.So, can reduce friction force between this rotating disk 100 and this supporting plate 300.More preferably, this rotating disk 100 is provided with this supporting plate 300 at interval.So, can further reduce friction force between this rotating disk 100 and this supporting plate 300.
