Abstract
The invention discloses a hole chamfering depth detection device which is composed of a bore dial indicator, a locating cone, a cylinder and a depth indicator. The bore dial indicator is vertically fixed to the center of the locating cone, and the lower end face of the cylinder coincides with the bottom end of the locating cone. The depth indicator is arranged on the cylinder. The included angle alpha between the bottom face and the conical face of the locating cone is identical to the chamfering angle of a workpiece hole so that it can be guaranteed that the conical face can be completely attached to the chamfering inclined face. The locating cone can guarantee the fact that the bore dial indicator is accurately located in the workpiece hole.
Description
Technical field
The present invention relates to a kind of detection tool, specifically a kind of pick-up unit of measured hole depth of chamfering.
Background technology
In mechanical processing industry, for the chamfering in hole, be seen everywhere, its object is all generally in order to remove the aperture burr after processing, to avoid the scuffing to people; But for some precision components, chamfering tends to play special role, such as the effect sealing, minimizing stress etc., so must to its size, control in strict accordance with product drawing in process.At present, the domestic and international depth of chamfering for hole does not still have a kind of simple and effective detection tool.
Summary of the invention
The pick-up unit that the object of this invention is to provide a kind of Hole chamfering degree of depth, it can be fast, convenient, the degree of depth of measured hole chamfering accurately.
To achieve these goals, technical scheme of the present invention is: a kind of Hole chamfering depth detection apparatus, by dial bore gage, setting circle cone, right cylinder and pit gauge, formed, dial bore gage is vertically fixed on the center of setting circle cone, cylindrical lower surface overlaps with the bottom of setting circle cone, and the two can be made of one; Pit gauge is arranged on right cylinder.
The bottom surface of setting circle cone is identical with the chamfer angle of conical surface angle α and workpiece hole, to guarantee that the conical surface and chamfering inclined-plane fit completely.Positioning cone body can guarantee the accurate location of dial bore gage in workpiece hole, thereby guarantees the accuracy of workpiece inside diameter measurement.
During actual use, setting circle cone is put into orifice chamfer place, makes dial bore gage accurate location in hole, and the internal diameter numerical value of measured hole, now can calculate the numerical value of L2; And then read to obtain the value of L1 from pit gauge, according to computing formula, obtain depth of chamfering numerical value L, and this numerical value can not be affected because of the variation of pore size.
The present invention in use can obtain Hole chamfering depth value by Measurement accuracy, and can not affect because of the variation in aperture the accuracy of its measurement; Have simultaneously simple in structure, use the features such as easy to operate, cost of manufacture is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Hole chamfering depth detection apparatus of the present invention.
In figure, 1-workpiece hole, 2-dial bore gage, 3-setting circle cone, 4-right cylinder, 5-pit gauge.
Embodiment
Details and the working condition of the concrete cubing proposing according to the present invention below in conjunction with accompanying drawing explanation.
Hole chamfering depth detection apparatus, by dial bore gage 2, setting circle cone 3, right cylinder 4 and pit gauge 5, formed, dial bore gage 2 is vertically fixed on the center of setting circle cone 3, and the lower surface of right cylinder 4 overlaps with the bottom of setting circle cone 3, and the two can be made of one; Pit gauge 5 is arranged on right cylinder 4.
The bottom surface of setting circle cone 3 is identical with the chamfer angle of conical surface angle α and workpiece hole 1, to guarantee that the conical surface and chamfering inclined-plane fit completely.Setting circle cone 3 can guarantee the accurate location of dial bore gage 2 in workpiece hole 1, thereby guarantees the accuracy of workpiece inside diameter measurement.
In the course of the work, setting circle cone 3 is put into orifice chamfer place, dial bore gage 2 is accurately located in hole, and the internal diameter numerical value of measured hole.
