Abstract
The invention relates to the technical field of internal and external conical surface conicity measuring devices, and specifically relates to a device for measuring conicity of internal and external conical surfaces. Conventional internal and external conical surface conicity measuring methods are characterized in that one method is manual measurement operated by a universal bevel protractor; the other method is automatic measurement operated by a three-coordinate measuring instrument; and the operation is complex, time-consuming and labor-consuming. A main measuring device provided by the invention is composed of an angle template, a long level meter, a sunk screw and a short level meter; and an auxiliary measuring device is composed of a standard measuring rod and a steel ball. When the main measuring device is independently used, the conicity of the external conical surface can be directly measured; and when the main measuring device and the auxiliary measuring device are matched for usage, the conicity of the internal conical surface can be measured. The internal and external conical surface conicity measuring device has the advantages that the design is ingenious, the structure is reasonable, the operation is simple, the measurement is accurate; in addition, when the conicity of the internal and external conical surfaces is measured, references are unified and superposed, and the influences of human factors on measurement data are totally avoided, so that the time for conicity measurement is rapidly shortened, the precision is greatly improved, the matched contact area between the internal and external conical surfaces is enlarged, and the matched connection between the conical surfaces is more firm and reliable.
Description
Technical field
The present invention relates to for inside and outside circle conical degree of conical surface measurement mechanism technical field, specifically a kind of device for measuring inside and outside circle conical degree of conical surface.
Background technology
The horizontal internal grinder of current use, horizontal cylindrical grinder, when being processed with the circular conical surface cooperatively interacting and require, traditional taper measurement method is, first find one with the reference measurement plane of measured circle conical surface central axis upright, then the base chi of general-purpose bevel protractor is attached in reference measurement plane, base chi is vertical and crossing with conical surface central axis, rotate general-purpose bevel protractor ratchet behind, ruler chi sword and the tested conical surface are developed, locking detent, observe main scale and vernier, determine to measure taper value.This measuring method, first requires reference measurement plane, must perpendicular to measured circle conical surface central axis, secondly the base chi of general-purpose bevel protractor, closely must develop accurate base measurement plane, can not have gap, again also require that operator has, use the measurement experience of general-purpose bevel protractor for many years; When measuring outer conical surface tapering if last, whole workpiece toply must to be unloaded from two of horizontal cylindrical grinder, could measure; If when measuring internal conical surface tapering, just necessarily require operator to use the method for range estimation, by the ruler of general-purpose bevel protractor, fit tightly with the side bus of internal conical surface or end bus, locking detent, determines taper value.This kind of measuring method and instrument, when measuring the tapering of the inside and outside circle conical surface, are measured difficulty comparatively large, are easily produced measuring error.
Summary of the invention
The object of this invention is to provide the device measuring inside and outside circle conical degree of conical surface, thoroughly solve in traditional measurement method, because the measurement of operator is lacked experience, the flatness error of measuring basis plane, the error of perpendicularity, etc. the measuring error that reason causes.When measuring inside and outside circular conical surface tapering, accomplish unifying datum, datum coincidence, get rid of human factor completely to the impact of measurement data, the time of measurement tapering is shortened rapidly, precision significantly improves, the cooperation contact area of interior male cone (strobilus masculinus) is strengthened, accomplishes that cone match connects more solid and reliable.
The technical solution adopted for the present invention to solve the technical problems is:
On horizontal cylindrical grinder, adopt two top clampings, when measuring tapering in the process of grinding outer conical surface, without the need to workpiece is unloaded from equipment, with the end inclined-plane of a hand by main measurement mechanism, be close to the bus position, top of the processing excircles conical surface, and around the neutral axis slight oscillatory of outer conical surface, make the short level vial of main measurement mechanism be in horizontality, now observe the state of long level vial again.The horizontality if the bubble of long level meter mediates, illustrates that the tapering of the tapering of present outer conical surface and tapering model is completely the same; If the bubble of long level meter is not in horizontality, just need to observe the position of bubble about long level meter between four grooves, by calculating the tapering of present outer conical surface, and the tapering difference between tapering fixed by tapering model, operator only need move equipment tailstock centre according to tapering difference, reconditioning outer conical surface repeatedly, can obtain the tapering of drawing technological requirement.
On horizontal internal grinder, when measuring tapering in the process of grinding internal conical surface, need first by the steel ball of aided measurement device, be close to acutangulate end crossing with internal conical surface, then rely on self gravitation that the canonical measure rod of aided measurement device is naturally drooped, and overlap completely with the end bus processing internal conical surface; Again by the inclined-plane, the end of main measurement mechanism, be close to the bus position, top of aided measurement device canonical measure rod, observe the position of bubble about long level meter between four grooves, by calculating the tapering of present internal conical surface, and the tapering difference between tapering fixed by tapering model, operator only need move the chuck of horizontal internal grinder according to tapering difference, reconditioning internal conical surface repeatedly, can obtain the tapering of drawing technological requirement.
The calibration steps of main measurement mechanism:
Because horizontal cylindrical grinder is when Installation and Debugging, adjust to level by top for the front and back two of equipment, so after fine ginding processing, the axial workpiece of any specification size, their top bus will be all a horizontal line.Therefore, only main measurement mechanism need be spun upside down 180 °, its top plane is close to the bus position, top of fine ginding processing rear axle, observe long level vial and whether be in horizontality, can know, whether the precision of main measurement mechanism is accurate.
The present invention design ingenious, rational in infrastructure, simple to operate, measure accurately; When measuring inside and outside circular conical surface tapering, accomplish unifying datum, datum coincidence, get rid of human factor completely to the impact of measurement data, the time of measurement tapering is shortened rapidly, precision significantly improves, the cooperation contact area of interior male cone (strobilus masculinus) is strengthened, accomplishes that cone match connects more solid and reliable.
