The device comprises a rack, a micro stepping motor suspended on an upper arm of the rack, a guide rail, and a threaded transmission sliding block matched with the guide rail and capable of sliding along the guide rail, wherein the micro stepping motor is used for driving a transmission screw rod which is in threaded fit with the threaded transmission sliding block through a speed-reducing mechanism, and the laser measurement device is mounted at the bottom of the threaded transmission sliding block. The device can improve the detection efficiency and the detection precision, and guarantee the safety of an operator.
Description
Technical field:
The utility model is relevant with aviation hydraulic system precision element sharp edge detection technique, and is relevant with aviation precision component sharp edge mensuration measurement mechanism especially.
Background technology:
The axle part of aviation hydraulic system is the critical component of aviation power topworks, and serviceability and sharp processing require very high.The seamed edge that forms for the cylindrical of part precision element or endoporus and annular groove intersection in the design requires to be sharp edge, is sharp edge according to seamed edge place circular arc R＜0.05 that generally requires of Machine Design.
Detection sharp edge size, traditional measuring method are to utilize optical projector, under the situation of 300 times of amplifications sharp edge are measured.This detection method is subject to following two factors: one, measuring accuracy is not high, has the error of 0.02～0.1mm.The one, the accuracy of detection of optical projector own is not high, and measuring error is about 0.01mm; The 2nd, this detection method is subjected to reviewer's operative skill bigger with the influence of the experience of detection.Longer owing to learning system in addition with the time that gets a distinct image at optical projector rise lay the grain, so the detection efficiency of this method is not high.
The utility model content:
The purpose of this utility model is in order to overcome above shortcoming, to provide a kind of and can improve detection efficiency, improving accuracy of detection, to the aviation precision component sharp edge laser measuring device for measuring of operator's safety.
The purpose of this utility model is achieved like this:
The utility model aviation precision component sharp edge laser measuring device for measuring, comprise frame, be suspended on little progress on the frame upper arm apart from motor, guide rail, cooperating with guide rail can be along the screw thread driving block of guide rail slip, driven by the microspur stepper motor with the drive lead screw of screw thread driving block threaded engagement by reducing gear, laser ranging system is loaded on the bottom of screw thread driving block, adopts Laser Microbeam to measure the shape of workpiece measuring point, obtains very high accuracy of detection and detection efficiency.
Above-mentioned reducing gear is a gear reduction.
Above-mentioned laser ranging system adopts Mark3.0 flash ranging head, and laser ranging system is produced for OPTIMET company, and laser source wavelength 1540nm is the eye-safe wavelength, has avoided the vision health infringement to the measuring operation personnel.
Frame hangs fixedly microspur stepper motor and guide rail.The microspur stepper motor slows down by reduction gearing mechanism, drives the drive lead screw rotation, moves as straight line along Z-direction thereby drive the screw thread driving block.By rotating in a circumferential direction in the process that straight line moves, the motion of motor is decelerated, the kinematic accuracy Be Controlled, thus the laser measuring device for measuring of having realized the driving block carrying moves in the high-precision slight distance of Z-direction.
In the measuring process, in the different position of Z-direction, laser measuring device for measuring obtains the tested profile position data of different X-directions, get at 3 at graphics plane, obtain one with 3 circles that pass through mutually, calculate this radius of a circle, just drawn the acute angle radius of the workpiece of surveying.
The utility model relies on the high precision of laser measurement, cooperates high-precision microspur step motion platform again, utilizes the sharp edge position of spot size for the laser beam flying part of 0.005mm.In the scanning process, by X, the Y-axis change in location of picking up three points, this moment, the image analysis of system calculated the radius of profile circular arc according to 3 circles that determined, can obtain the data of sharp edge size.Because laser beam is 0.001mm at X to the sensitivity that detects, Z can be controlled in＜0.005mm to the precision of motion, so plant the measuring error ≯ 0.01mm of detection method.
The sharp edge that the utility model can be used for a part and other structural member detects, and the supervision time is fast, checks the precision height, can effectively increase work efficiency safety.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
Referring to Fig. 1, present embodiment aviation precision component sharp edge laser measuring device for measuring comprises the frame 1 that is contained on the base 12, is suspended on microspur stepper motor 2 on the frame upper arm, guide rail 3, cooperates the screw thread driving block 4 that can slide along guide rail with guide rail.Driven by microspur stepper motor 2 with screw thread driving block threaded engagement and drive lead screw 8 that be bearing on the frame by block bearing 6 by gear reduction 5
Laser ranging system 9 is loaded on the bottom of screw thread driving block.Sequence number 10,11,13,7 is respectively laser beam, workpiece to be measured among the figure
Workpiece sharp edge to be measured, measurement point.
The Mark3.0 laser feeler that laser ranging system adopts OPTIMET company to produce, measuring accuracy is 0.2 micron.
