Description

The right alignment detector in parallel plane hole

Technical field

The utility model relates to the right alignment detector in a kind of parallel plane hole, and it belongs to the pick-up unit of the right alignment in a kind of mechanical detection parallel plane hole.

Background technology

The detection of parallel plane hole right alignment is adopted the receiver ga(u)ge of control actual effect border principle to detect usually or is adopted the receiver ga(u)ge of measurement features parameter principle to detect.The receiver ga(u)ge of control actual effect border principle detects right alignment can only provide qualitative conclusion, can't quantize.And adopt the receiver ga(u)ge detection right alignment of measurement features parameter principle unidirectionally to measure, and can't realize comprehensive measurement, can't embody the distribution orientation of off-axis, and all be the special use of special hole in tolerance range, economy is bad.Defectives such as therefore, the device of existing detection right alignment exists and detects inconvenience, parameter can not quantize and less economical.

Summary of the invention

The purpose of this utility model be solve that detection inconvenience, parameter that the existing device that detects right alignment exists can not quantize and less economical technological difficulties and provide a kind of easy to detect, parameter can quantize, precision reliably and the right alignment detector in the parallel plane hole of good economy performance.

For realizing above-mentioned task, the technical solution adopted in the utility model is: the right alignment detector in this parallel plane hole, it comprises the detent mechanism that is made of locating detent, rotating disk and pinch wheels, the matrix of scale, hollow cylinder and end cap, wherein: it also comprises measuring mechanism and the self-aligning bearing of being made up of vernier scale, rotating shaft and measuring staff; Scale is located on the large end face of matrix of hollow cylinder, and self-aligning bearing is located in the hole of the matrix other end of hollow cylinder and is fixed on end cap on the matrix of hollow cylinder; Vernier scale is connected with an end of rotating shaft and is contained on the scale, and rotating shaft is contained in the hole of self-aligning bearing, and measuring staff is located at the head of the rotating shaft other end; Rotating disk is located at the inboard of location end face of the matrix of hollow cylinder, and locating detent is located on the rotating disk, and pinch wheels is located between rotating disk and the scale and is positioned at the holes for clamping place of the matrix of hollow cylinder.

Because the utility model has adopted the technical scheme of above-mentioned vernier scale form, therefore can accurately detect right alignment and quantized data can directly be provided, comprehensive demonstration deviation azimuth, precision can reach 0.02mm.Compare with background technology, have easy to detect, parameter can quantize, precision is reliable and advantage such as good economy performance.
