Abstract
The utility model discloses long detection device in a kind of workpiece, including fixed seat, it is symmetrically mounted in fixed seat and respectively towards the light source on the step above groove along fillet direction transmitting light, for receiving the camera lens of reflection light, and it is connected with camera lens, the ccd sensor for converting optical signals to electric signal；The light barrier for preventing light source to be irradiated to root fillet is additionally provided with fixed seat.The utility model by light barrier by being placed in roots Level, step is irradiated with the bright LED source of light barrier rear end, since root fillet is blocked by light barrier, light can not be irradiated to, therefore there is light reflection along fillet only on step, ccd sensor utilizes the reflected light, you can long side position in accurate acquisition.The utility model can obtain the interior long size of workpiece exactly, by the order of magnitude of precision improvement to 0.01mm than original measuring method.
Description
Technical field
It the utility model is related to long detection device in engineering measurement field, more particularly to a kind of workpiece.
Background technology
A kind of known nonpenerative aluminum alloy part in bottom, the surface of the part set fluted, and when detection is needed to this
The length (long in i.e.) of groove measures.The method being commonly used is to coordinate traditional polishing mode to be examined using CCD
Survey, after blasting craft of the right angle wedge angle before surface treated at groove upper step, inevitably cause straight
The top of the horn angle rust, forms certain fillet, and light can reflex to ccd sensor when being irradiated to the fillet, through analog-to-digital conversion imaging,
And then complete measurement.
, also can shape in foregoing roots Level but aforesaid way is subject to processing the influence of tool wear in practical operation
Into fillet, due to that, along fillet, all light can be reflexed to ccd sensor, so as to be formed on root fillet when light irradiates, step
Two highlighted bands.Therefore the interior long side for being actually subjected to collection can be hidden in the bright band, it is difficult to accurate discrimination, also just can not be internal
Long size measures.
Utility model content
In order to overcome the problems referred above, the utility model provides long detection device in a kind of workpiece, solves existing apparatus measurement
Low precision, the problem of can not accurately obtaining long size in workpiece.
Technical solution is used by the utility model solves its technical problem：Long detection device, is used in a kind of workpiece
The groove length of measured workpiece is measured, it includes fixed seat, is symmetrically mounted in fixed seat and respectively towards the step above groove
On along fillet direction transmitting light light source, for receiving the camera lens of reflection light, and be connected with camera lens, for by optical signal
Be converted to the ccd sensor of electric signal.The light barrier for preventing light source to be irradiated to root fillet is additionally provided with the fixed seat.
Further, above-mentioned light source is LED light source.Light barrier is made by nonmetallic materials.
The beneficial effects of the utility model：
The utility model irradiates step by the way that light barrier is placed in roots Level, with the bright LED source of light barrier rear end,
Since root fillet is blocked by light barrier, light can not be irradiated to, therefore have light reflection along fillet only on step, and CCD is passed
Sensor utilizes the reflected light, you can long side position in accurate acquisition.The utility model, can be more accurate than original measuring method
Ground obtains the interior long size of workpiece, by the order of magnitude of precision improvement to 0.01mm.
Below with reference to drawings and examples, the utility model is described in detail.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is partial enlarged view at the A of Fig. 1.
In figure, 10, measured workpiece, L, interior length, 1, fixed seat, 2, light source, 3, camera lens, 4, ccd sensor, 5, light barrier,
6th, on step along fillet, 7, fixture, 8, root fillet.
Embodiment
Embodiment,
Also referring to Fig. 1 to 2, long detection device in a kind of workpiece, for measuring long L in measured workpiece 10, it is wrapped
Include fixed seat 1, LED light source 2, camera lens 3, ccd sensor 4 and light barrier 5.
Wherein, LED light source 2 is symmetrically arranged with two groups, it is installed in fixed seat 1 and is respectively facing the platform above groove
Launch light along 6 direction of fillet on rank.The plane that the transmitting light of two groups of LED light sources is formed and 10 place plane phase of measured workpiece
It is mutually vertical.
Camera lens 3 is used to receive the incident ray reflected along fillet 6 from step, and is connected with ccd sensor 4.
Ccd sensor 4 is connected with camera lens 3, and it is defeated that its incident optical signal for being used to receive on camera lens is converted to electric signal
Go out.
Light barrier 5 is installed in fixed seat 1 by fixture 7, it is used to prevent the transmitting light of LED light source 2 to be irradiated to root
Portion's fillet 8.
The above is only the preferred embodiment to utility model, and not the scope of utility model is defined, therefore
On the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to construction described in the utility model, spy
The equivalence changes or decoration that sign and principle are made, should all fall into the scope of protection of the utility model.
