Abstract
The invention relates to the field of mechanical measurement, in particular to a precision detecting device. The precision detecting device comprises a locating shaft and dial indicators, one end of the locating shaft is sleeved with a bush, a locating segment is arranged at the other end of the locating shaft, a first support is arranged on one side wall of the bush, the first dial indicator and a measuring rod are arranged on the first support, protrusions are arranged at the two ends of the measuring rod, and one protrusion corresponds to a measuring head of the first dial indicator. A second support is arranged on the other side of the bush, and the second dial indicator is arranged on the second support. According to the technical scheme, the technical problems that three-dimensional equal-height end equipment is used for detecting the coaxiality and perpendicularity of workpieces in the prior art, operation is complex, and efficiency is low are mainly solved.
Description
Technical field
The present invention relates to mechanical measurement field, refer more particularly to a kind of accuracy detecting device.
Background technology
The verticality of the endoporus of traditional detection workpiece and the right alignment of external diameter, endoporus and large end face can only detect with the contour end instrument of three-dimensional, accuracy of detection is high, but equipment price is expensive, complicated operation, detection efficiency low (detecting two key elements about 1 hour), the requirement of testing staff is high, needs professional personage and tool qualification on duty.
Summary of the invention
What the present invention mainly solved is utilize high-end equipment Inspection workpiece right alignment and the verticality such as three-dimensional in prior art, complicated operation and inefficient technical matters.
In order to solve the problems of the technologies described above, the technical program provides a kind of accuracy detecting device, comprise locating shaft and dial gauge, one end of described locating shaft is provided with lining, the other end of locating shaft is positioning section, and a sidewall of lining is provided with the first support, and this first support is provided with the first dial gauge and sounding rod, the two ends of described sounding rod are with projection, and wherein one is protruding corresponding with the first dial indicator measuring head.The opposite side of lining is provided with the second support, and the second support is provided with the second dial gauge.
Adopt technique scheme, during measurement, workpiece for measurement is installed on locating shaft, turn on the bolt on the first support, promote the first dial gauge protruding near one end of sounding rod, sounding rod is rotated, middle part due to sounding rod is hinged on the first support, its other end also rotates thereupon, until sounding rod lower end projection contacts with workpiece inner wall, tighting a bolt is fixed on the first dial gauge on the first support.Again by the bolt on adjustment second support, the upper surface probe of dial gauge being pasted contact workpiece for measurement perpendicular to the radial line of workpiece.Now, turning of work piece, workpiece inner wall is beated along sounding rod and is passed to the first dial gauge, and workpiece surface is beated along measuring head and is passed to the second dial gauge.Only need check the variation shown by two dial gauges, just can while obtain right alignment and the verticality of workpiece accurately, simple to operate and precisely effective.
Further, in order to the state making locating shaft and lining reach compact, described locating shaft and lining are that small―gap suture coordinates.
Further, the middle part of described sounding rod is hinged on the first support, makes sounding rod can do corresponding rotation thereupon the adjustment of the first dial gauge, thus makes one end of sounding rod can accurately be affixed tactile with workpiece inner wall.
Further, the first dial gauge and the second dial gauge are arranged on the first support and the second support by bolt is adjustable.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of accuracy detecting device of the present invention.
Embodiment
As shown in Figure 1, the technical program is a kind of accuracy detecting device, comprise locating shaft 3 and dial gauge, one end of locating shaft 3 is provided with lining 4, both adopt small―gap suture fit system to install, and the other end of locating shaft 3 is positioning section, and a sidewall of lining 4 is provided with the first support 5, this first support 5 is provided with the first dial gauge 1 and sounding rod 6, first dial gauge 1 is arranged on the first support 5 by bolt 8 is adjustable.First support 5 is hinged with sounding rod 6, and the measuring head of sounding rod 6 and the first dial gauge 1 is perpendicular, and the left side sidewall of this sounding rod 6 is also provided with two projections 7, and upper end projection 7 is corresponding with the first dial gauge 1 measuring head.The opposite side of lining 4 is provided with the second support 9, second support 9 and is provided with that the second dial gauge 2, second dial gauge 2 is adjustable to be arranged on the second support 9.
During measurement, workpiece for measurement 10 is installed on locating shaft 3, turn on the bolt 8 on the first support 1, promote the upper end projection 7 of the first dial gauge 1 near sounding rod 6, make sounding rod 6 upper end to right rotation, the middle part due to sounding rod 6 is hinged on the first support 5, and its lower end is to anticlockwise, until sounding rod 6 lower end protruding 7 and workpiece 10 contact internal walls, tighting a bolt 8 is fixed on the first dial gauge 1 on the first support 5.Again by the bolt 8 on adjustment second support 9, the upper surface measurement head of the second dial gauge 2 being pasted contact workpiece for measurement 10 perpendicular to the radial line of workpiece 10.Now, turning of work piece 10, workpiece 10 inwall is beated along sounding rod 6 and is passed to the first dial gauge 1, and workpiece 10 upper surface is beated along measuring head and is passed to the second dial gauge 2.Only need check the variation shown by two dial gauges, just can obtain right alignment and the verticality of workpiece, simple to operate and precisely effective.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
