Abstract
The utility model relates to a caliper for measuring the chamfer angle of a part, comprising a reference rod, a ruler frame, and a pressing plate. A groove on the upper part of the ruler frame is internally provided with the reference rod, the front of the reference rod is provided with an angle sample piece, the front of the lower half part of the angle sample piece is provided with the pressing plate, and the pressing plate limits the angle sample piece in the ruler frame groove through a cross recessed countersunk head screws; the upper end face of the ruler frame is provided with a fastening screw which limits the movement of the reference rod, the lower end face of the angle sample piece is provided with a flat-end roller pin, the lower side of the flat-end roller pin is provided with a fastening screw, and the fastening screw limits the movement of the angle sample piece through the flat-end roller pin. The caliper for measuring the chamfer angle of the part has the advantages of excellent performance, convenient operation, accurate measurement data, and wide range of application, and can directly and accurately measure the chamfer angle of the part.
Description
Technical field
The utility model relates to measurement instrument, particularly relates to a kind of measurement part chamfer angle slide calliper rule.
Technical background
Slide calliper rule are used for the mechanical component measurement of length because measurement is accurate, easy to use always, when some part has requirement to chamfering, can not carry out direct reading to the size of any chamfering workpiece with slide calliper rule and measure, and usable range has been subject to certain restriction.
Summary of the invention
The purpose of this utility model provides a kind of measurement part chamfer angle slide calliper rule, and it is easy to operate, measurement data is accurate, usable range is wide, can be to the direct Measurement accuracy of part chamfering angle size.
The purpose of this utility model is to realize like this, a kind of measurement part chamfer angle slide calliper rule, comprise baseline rod, chi frame, pressing plate, it is characterized in that: be provided with baseline rod in the described chi frame upper grooves, the baseline rod front is provided with angle sample piece, angle sample piece Lower Half front is provided with pressing plate, and pressing plate is limited in angle sample piece in the chi frame groove by cross recessed countersunk head sscrew; Chi frame upper surface is provided with the trip bolt of restriction baseline rod motion, and angle sample piece lower surface is provided with flat end needle rollers, is provided with trip bolt below the flat end needle rollers, and trip bolt is by the motion of flat end needle rollers limited angular sample piece.
Baseline rod described in the utility model, angle sample piece adopt clearance fit in the groove of chi frame and pressing plate composition.
The utility model is easy to operate, measurement data is accurate, usable range is wide, can be to the direct Measurement accuracy of part chamfering angle size.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing, a kind of measurement part chamfer angle slide calliper rule, comprise baseline rod 1, chi frame 6, pressing plate 10, it is characterized in that: be provided with baseline rod 1 in described chi frame 6 upper grooves, baseline rod 1 front is provided with angle sample piece 7, angle sample piece 7 Lower Half fronts are provided with pressing plate 10, and pressing plate 10 is limited in angle sample piece 7 in chi frame 6 grooves by cross recessed countersunk head sscrew 9; Chi frame 6 upper surfaces are provided with the trip bolt 5 of restriction baseline rod 1 motion, and angle sample piece 7 lower surfaces are provided with flat end needle rollers 11, are provided with trip bolt 5 below the flat end needle rollers 11, and trip bolt 5 is by 7 motions of flat end needle rollers 11 limited angular sample pieces.Described baseline rod 1, angle sample piece 7 adopt clearance fit in the groove that chi frame 6 and pressing plate 10 form.During implementation, chi frame and angle sample piece groove principle: it is reference field that chi frame longitudinal edge is set, and the distance between the first piece lines of reference field to the chi frame is chi frame " 0 " linear distance X; It is reference field that angle sample piece longitudinal edge is set, distance between the first piece lines of reference field to the angle sample piece is angle sample piece " 0 " linear distance Z, the width that angle sample piece longitudinal terminal surface is set is Y, the inclined-plane that angle sample piece becomes is measurement datum, angle [alpha] is any chamfer angle of required measurement, so Z=X+Y/tg α.The utility model has multiple angles sample piece, select as required required angle sample piece, baseline rod, angle sample piece are positioned in the chi frame groove successively, pass pressing plate with two cross recessed countersunk head sscrews, pressing plate is fixed on the chi frame, baseline rod, angle sample piece can only be moved back and forth between chi frame groove and pressing plate.The baseline rod motion can be limited with trip bolt in chi frame upper surface, and chi frame lower surface adds the together limited angular sample piece motion of fastening screw with adding flat end needle rollers.Before the use, unclamp respectively chi frame upper and lower end trip bolt, and baseline rod, angle sample piece steadily pulled open, with clean soft cloth baseline rod is measured face, chi frame reference field, angle sample piece measurement datum and wipe clean, " 0 " line on the angle sample piece is overlapped can use fully with " 0 " line on the chi frame.During measurement, first " 0 " line on the chi frame 6 is overlapped with angle sample piece 2 " 0 " line complete matchings, the chamfering end face of part to be measured is leaned against on the reference field of chi frame left side, the upper plane of measuring part leans against the baseline rod lower plane, then touch angle sample piece 2 left, make the measurement datum of angle sample piece 2 fully identical with the measured workpiece fillet surface, directly read the reading on the slide calliper rule this moment, be the physical size How many millimeters of tested chamfering, according to the number of degrees of chosen angle sample piece, know that namely this part chamfering is how many degree of How many millimeters X.
