Description
Technical field
The utility model relates to a kind of measurement of angle instrument, but especially relates to a kind of vernier taper gauge of measuring workpieces taper value.
Background technology
Existing " omnipotent vernier bevel protractor " is to be used for the precision measuringtoll of measuring workpieces angle, and its measurement range is 0 °～320 °, the measuring accuracy of vernier reaches 2 '.During measurement, should make bevel protractor measure face and ruler measurement face and measured workpiece surface and be adjacent to, can obtain the exact value of workpiece angle.
Circular cone or round platform are a kind of common workpiece, and its taper value is most important measuring index, and in the processing and checkout procedure of workpiece, the work of measuring its taper value is indispensable link.Because the object that " omnipotent vernier bevel protractor " measured is the workpiece that angle is formed on two planes, its bevel protractor is measured face and ruler measurement face is long and narrow plane, these two long and narrow measurement faces are difficult to keep stable contacting with the curved surface outer of circular cone or round platform, the axis that also can't guarantee two center lines of measuring faces and workpiece is in the same plane, therefore " omnipotent vernier bevel protractor " taper value of energy measurement circular cone or round platform not.
The measuring workpieces tapering adopts taper gage to measure and measure indirectly two kinds of methods usually.The taper gage mensuration is several special cone angles that equate with gauge block of energy measurement only, and other cone angle is then powerless, and its shortcoming is that practicality and versatility are relatively poor; The indirect method of measurement is by the external diameter value of measuring circular cone or round platform and the height value of certain funtcional relationship arranged with it, through calculating the method that obtains indirect consequence, its shortcoming be error greatly and calculate loaded down with trivial details.
Summary of the invention
The purpose of this utility model aims to provide a kind of vernier taper gauge that can directly measure circular cone or round platform taper value.
The utility model is provided with vernier bevel protractor and cone locating device, described cone locating device is provided with prelocalization slide block and back positioning sliding block, described prelocalization slide block and back positioning sliding block are located on the ruler of vernier bevel protractor front and back respectively, be provided with the front slide groove that cooperates with ruler in the middle part of prelocalization slide block vertical direction, middle part vertical direction at the back positioning sliding block is provided with the back sliding tray that cooperates with ruler, be respectively equipped with the front limit groove vertical with the front slide groove in front slide groove both sides, be respectively equipped with and the vertical back stopper slot of back sliding tray in sliding tray both sides, back, be provided with the prelocalization holder chi of symmetric offset spread in the both sides on prelocalization slide block top, also be provided with the back location holder chi of symmetric offset spread in the both sides on positioning sliding block top, back, be provided with preceding through hole at the prelocalization slider bottom, be provided with the back through hole in positioning sliding block bottom, back.
The horizontal sextant angle of the prelocalization holder chi of described symmetric offset spread can be 25 °～35 °, and the horizontal sextant angle of the back location holder chi of described symmetric offset spread can be 25 °～35 °.
Described prelocalization slide block can be connected with ruler by front limit pin, preceding trimming bolt, preceding fine-tuning nut and preceding compression spring, described back positioning sliding block can be connected with ruler by back spacer pin, back trimming bolt, back fine-tuning nut and back compression spring, and prelocalization slide block and back positioning sliding block all can move up and down and fix.
Described prelocalization slide block can be in the form of sheets, and described back positioning sliding block also can be in the form of sheets.Described prelocalization slide block is preferably identical with size with the shape of back positioning sliding block.
During use, the outer with circular cone or round platform places the ruler top earlier, adjusts the height and the rotational angle chi of former and later two positioning sliding blocks then respectively.When the location holder chi of ruler measurement face, positioning sliding block both sides, front and back, when bevel protractor measurement face all is adjacent to the outer of circular cone or round platform, the data that bevel protractor and vernier scale superposeed are the taper value of measured workpiece.If only need the angle value of measuring workpieces, can unload positioning sliding block or change the ruler of joining in addition, can recover the repertoire of " omnipotent vernier bevel protractor ".
The utility model is on existing " omnipotent vernier bevel protractor " basis, increased easy cone locating device, the function and the advantage that not only keep the accurate measuring workpieces angle value of omnipotent vernier bevel protractor, and made it to rise to the aspect of accurate measuring workpieces taper value, can also impel axis and two center lines of measuring face of circular cone or truncated cone-shaped workpiece in the same plane, thereby obtain the taper value of degree of precision.Have characteristics such as simple and reliable for structure, easy to operate, multiple functional, highly versatile, for the processing of mechanical industry, maintenance, reviewer's work provides a kind of precision measuringtoll of practicality.
