Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical synoptic diagram of measuring principle of the present utility model;
Fig. 3 is the horizontal synoptic diagram of measuring principle of the present utility model.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only for the utility model is described, rather than in order to limit protection domain of the present utility model.
As shown in Figure 1, taper hole cone angle error of the present utility model compares and measures instrument, comprise clock gauge 7 and grip part 9, the below of grip part 9 is vertically installed with installation shaft 8, axially being disposed with clock gauge clamping device 4, measuring unit dish 2 and locating frustum 1 along installation shaft 8; Wherein, location frustum 1 upside down little and be arranged on the installation shaft 8 in mode along installation shaft 8 circumferencial direction secure fit.
Measuring unit dish 2 is arranged on the installation shaft 8 in the mode that is slidingly matched along the installation shaft circumferencial direction, measuring unit dish 2 comprises to be measured circle guiding element portion 21 and is arranged on the main setting circle guiding element portion 22 of measuring circle guiding element portion 21 belows, measure the end face of circle guiding element portion 21 and the gauge head of clock gauge 7 and be oppositely arranged, be connected with compression spring 3 between the end face of measurement circle guiding element portion 21 and the lower end of clock gauge clamping device 4; Compression spring 3 is gasket construction and is sleeved on the installation shaft part of measuring between circle guiding element portion's 21 end faces and clock gauge clamping device 4 lower ends.
Be provided with quakeproof rubber pad 11 between the lower end of measuring unit dish and the location frustum, its role is to when measurement finishes the pressure disappearance, can reduce measuring unit dish 2 impulsive force for location frustum 1 when return, reduce system wear.
Measuring principle of the present utility model is:
As Fig. 2, shown in Figure 3, wherein A represents the less cross section circle of circular conical surface, and B represents the bigger cross section circle of circular conical surface.
By the computing formula tg α of semi-cone angle α=(D-d)/2L as can be known: (wherein, α is a semi-cone angle, and D is a circular conical surface larger cross-section diameter of a circle; D is a circular conical surface small cross sections diameter of a circle; L is in the axial direction a distance between the two sections circle)
Under the situation that the cross section circular diameter is fixed (numerical value that is D-d is fixed), the size of processing parts cone angle error Δ α can reflect by the difference DELTA L that compares axial distance L between part and the standard component, thereby directly whether the error in judgement value closes the symbol requirement.
