Background technology
The part that hole axle class cooperates is widely used in various fields such as machinery industry, aviation field, marine ships, it is reported the proportion of hole axial workpiece in occupation of 60%.The a survey report of research institution of Britain imperial family points out, the mechanical disorder 50% or more all causes owing to the drive apparatus coupling misalignment.In industries such as electric power, petrochemical industry, machinings, the axle of the rotating machineries such as gas-turbine, blower fan, motor, compressor, pump and lathe ties up to all will carry out Alignment measuring when installing and keeping in repair, centering directly affects the normal operation of unit, and effectively the right alignment of measured hole axial workpiece is to guarantee such part effectively prerequisite and the basis of work.
Also be various to the measuring method of hole type parts at present, emerge in an endless stream, comprise clearance gauge method, ruler method and the dial gauge mensuration, also have various laser alignment instruments etc.But the part coaxality measurement for overlength array hole system fails to find a kind of suitable measuring method all the time.And this class part proportion is especially outstanding at aviation field, substantially all is the overlength array hole such as the link of aircraft flaperon.The manual feeler gauge mensuration of general employing in the industry, this method reliability and work efficiency are not very desirable.
Summary of the invention
The purpose of this utility model provides a kind of comprehensive gauge head unit of self-centering of multi-holes part coaxality measurement, to realize that gathering measured hole is some parameter informations of inside surface, these information spinners will comprise internal diameter and the hole position in system's absolute coordinates of hole system, and then can the faster qualification of judging more accurately the multi-holes part right alignment.
The technical solution of the utility model: the comprehensive gauge head unit of a kind of self-centering of multi-holes part coaxality measurement, comprise the comprehensive gauge head of the self-centering that is consisted of by three-jaw self-centering chuck, ratchet, direct current generator and be installed on the PSD sensor of the comprehensive gauge head front end of self-centering, be provided with photoelectric encoder at the comprehensive gauge head of self-centering.
Also be provided with locating slot on the comprehensive gauge head of self-centering, orientation lever inserts or extracts by positioning step and the locating slot of its below.
On the described orientation lever indicating circuit is installed.
The beneficial effects of the utility model: 1. photoelectric encoder is that light harvesting, mechanical, electrical technology are in the digital sensor of one, corner or straight-line displacement amount that can the high-acruracy survey measured object, owing to having adopted photoelectric encoder, data can gather automatically, automatically detect, data are processed more accurately and reliably, have therefore avoided artificial lengthy and jumbled measurement and the process of deal with data, can change radial dimension into corresponding electric signal by photoelectric encoder, electronic operation has improved work efficiency; 2. orientation lever inserts or extracts by the positioning step below it and locating slot and can guarantee that measuring process all is in a fixing frame of reference, has guaranteed measuring accuracy; 3. on the orientation lever indicating circuit is installed, on the indicating circuit of a branch of directed Ear Mucosa Treated by He Ne Laser Irradiation that parallels with reference laser to the orientation lever, realizes the aligning indicative function to comprehensive probe location.

Embodiment
As depicted in figs. 1 and 2, the comprehensive gauge head unit of a kind of self-centering of multi-holes part coaxality measurement, comprise the comprehensive gauge head 102 of the self-centering that is consisted of by three-jaw self-centering chuck 202, ratchet 204, direct current generator 205 and be installed on the PSD sensor 201 of comprehensive gauge head 102 front ends of self-centering, be provided with photoelectric encoder 203 at the comprehensive gauge head 102 of self-centering.
As shown in Figure 3, also be provided with locating slot 303 on the comprehensive gauge head 102 of self-centering, orientation lever 301 inserts or extracts with locating slot 303 by the positioning step 302 of its below.
On the described orientation lever 301 indicating circuit is installed.
Principle of work and the course of work: PSD sensor 201 is used for receiving the positional information of reference laser beam interferes; Three-jaw self-centering chuck 202 utilizes three jaw self-centering principles, indirectly finds the center in tested aperture; Photoelectric encoder 203 is used for the three-jaw expansion amount of record three-jaw self-centering chuck 202, to be used for the calculated hole diameters internal diameter; Ratchet 204 belongs to system's force measuring machine, when three-jaw gauge head and tested aperture contact force reach predetermined value, driving-chain is thrown off, guarantee that the motor rotation amount can not damage the three-jaw gauge head of measured surface, makes unnecessary motor rotation amount not affect the counting of scrambler simultaneously; Direct current generator 205 is used for providing power to device.
During measurement, the comprehensive gauge head 102 of self-centering is put in the measured hole, give direct current generator 205 enabling signals, direct current generator 205 begins rotation, the rotation amount of direct current generator 205 is changed into the radial displacement of three measuring jaws of three-jaw self-centering chuck 202 by a series of mechanical transmission component.Three measuring jaws are symmetrical and have identical motion state, so when the outside of three measuring jaws and tested aperture close contact, can think that the symcenter of three measuring jaws is exactly the center of measured hole.The centre coordinate position of three measuring jaws obtains by being installed in the comprehensive gauge head 102 of self-centering PSD sensor 201 foremost, because the comprehensive gauge head 102 of PSD sensor 201 and self-centering is to be rigidly connected, therefore its mutual position relationship is changeless, and the measurement for each center, hole of hole system just can utilize the geometric center of PSD sensor 201 to find the center in tested aperture like this.Each measured hole center is input in the computer system, utilizes software program to calculate the right alignment value of this hole system.The effect of photoelectric encoder 203 is to measure the scene motion rotation amount of three-jaw self-centering chuck 202 from contraction state to complete and endoporus contact condition, after converting, obtains the inner diameter values in hole.According to the right alignment value and the inner diameter values that obtain, require to judge in conjunction with concentricity tolerance, id tolerance whether tested part satisfies the tolerance of right alignment, internal diameter, thereby determine the qualification of part.
When measuring a certain hole, also need a reference laser to project the measuring basis that on the PSD sensor 201 as whole hole is, by the position coordinates of hot spot on PSD sensor 201 that calculates reference laser, between the coordinate center of this laser coordinate point and PSD sensor 201 itself skew is arranged, this side-play amount has just reflected the side-play amount between measured hole center and the measuring basis.After measuring a series of apertures, according to the position coordinates (side-play amount) of center, a series of hole with respect to reference laser, utilize fitting algorithm, in three-dimensional system of coordinate, can simulate porose actual axis, further can calculate the right alignment in all apertures.
In measuring process, allow orientation lever 301 remain and can receive directed laser, because directed laser beam is fixed, therefore, can guarantee gauge head within the specific limits, there is not the axis rotation around self.
