Description
Technical field
The present invention relates to deep hole field, and in particular to a kind of measuring system for being used to measure deep hole perpendicularity.
Background technology
Hole depth is typically referred to as deep hole more than five times of aperture cylindrical hole, and Deep-Hole Drilling Technology is in national defense industry, stone
Oily digging, Aero-Space, lathe, automobile and other industries are quite widely applied, and due to its efficiently, high accuracy etc. it is superior
Property, Deep-Hole Drilling Technology is also applied in the shallow bore hole processing of some parts.In recent years, the development of Deep-Hole Drilling Technology is very
Hurry up, research of China's machine-building processing industry to Deep-Hole Drilling Technology also achieves significant progress, such as by gun drilling with it is low
Frequency vibration cutting combines the deep hole Vibrational Drilling Technology to be formed, drill gun system, drilling system, deep hole core drill and cuts system etc.
Also there is corresponding research and innovate.
The content of the invention
The technical problems to be solved by the invention are the phenomenons that existing deep hole easily drills through out of plumb, and due to
The various factors such as its environment, the measurement of the perpendicularity of deep hole is inconvenient, it is therefore intended that provide a kind of for measuring deep hole perpendicularity
Measuring system, solve be not easy to measure deep hole diameter perpendicularity the problem of.
The present invention is achieved through the following technical solutions：
A kind of measuring system for being used to measure deep hole perpendicularity, including measure and control device, the measure and control device include control mould
Block and computing module, the control module are connected with expansion link drive module, pressure sensor, some current vortex displacements sensing
Device, the eddy current displacement sensor is connected with pretreatment module, and the pretreatment module is connected with each other with computing module, described
Computing module is connected with control module.
A kind of measuring system for being used to measure deep hole perpendicularity, the measure and control device includes being columned expansion link, institute
The side that eddy current displacement sensor is connected to expansion link is stated, and relative two eddy current displacement sensors place straight line is
Straight line where flexible shank diameter.
A kind of measuring system for being used to measure deep hole perpendicularity, the pressure sensor is connected to the bottom of expansion link.
A kind of measuring system for being used to measure deep hole perpendicularity, some eddy current displacement sensors share a CPLD
Programmable digital signal generator.
Further, the eddy current displacement sensor of the system be used to sensing eddy current displacement sensor and inner walls of deep holes it
Between distance, and the signal sensed is passed into pretreatment module, pretreatment module is located in advance to the data received
Reason, then computing module is passed data to, the computing module is used for calculating and handles obtained data, finally obtains in expansion link
During moving down, diameter of the deep hole tested at diverse location finally sends the data to controller, and controller leads to
Cross data and judge whether tested deep hole is vertical.
Further, the expansion link of the system is a cylinder, and the side of expansion link is connected with some current vortexs
Displacement transducer, straight line where the eddy current displacement sensor is even number, and every a pair of eddy current displacement sensors all exists
Where the diameter of expansion link on straight line, so when testing the internal diameter of deep hole, expansion link without rotation, in computing module plus and
Relative to one group of eddy current displacement sensor data, and then during being moved down with expansion link, can detect the interior of deep hole
The change of diameter, and pressure sensor is located at the bottom of expansion link, when expansion link touches the bottom of deep hole, pressure sensing
Device experiences pressure, and one signal of transmission is to controller, and controller, which sends signal, makes expansion link stop elongation, and starts contracting
It is short.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of measuring system for being used to measure deep hole perpendicularity of the present invention, perpendicularity of the system inside test deep hole
When, it will not be in contact with inner walls of deep holes, damage when can be prevented effectively from contact to inner walls of deep holes；
2nd, a kind of measuring system for being used to measure deep hole perpendicularity of the present invention, the system contains multipair current vortex displacement sensing
Device, multipair data can be obtained simultaneously in measurement, so more accurate in measurement, for last perpendicularity detection also more
Plus it is accurate；
3rd, a kind of measuring system for being used to measure deep hole perpendicularity of the present invention, the system measurement is easy, is easy to operation.
