Abstract
The invention discloses an inner-diameter identification device which includes a transportation channel used for transporting annular workpieces; a column body arranged at an exit of the transportation channel and used for obtaining annular workpieces; and sensors arranged at the two sides of the column body and used for detecting the types of the workpieces, wherein the column body is arranged telescopically and when the column body extends, the workpieces can be taken out and when the column body contracts, the workpieces are released; the column body has different upper-part and lower-part diameters and the upper-part diameter is smaller than the lower-part diameter. In the inner-diameter identification device, different diameters are arranged for upper and lower parts of the workpiece-taking column and large workpieces fall into the lower-part diameter and small workpieces sleeve the upper-part diameters and then the types of workpieces are identified through the sensors. The inner-diameter identification device is simple in process, high in work efficiency and low in design cost.
Description
Technical field
The present invention relates to a kind of recognition device, relate in particular to a kind of internal diameter recognition device.
Background technology
Industrially use sometimes a kind of annular workpieces, in the middle of it, there is circular through hole, precision machined occasion, the requirement of the concentricity to inner hole of workpiece is very high, therefore conventionally after producing, need to detect to classify, the means that at present concentricity of circular hole detected are many, such as using dial gauge, three-dimensional detection amount machine, concentricity measuring instrument device etc.These checkout equipments are generally more expensive, and complicated operation, and efficiency is low, greatly increased the manufacturing cost of workpiece.
Therefore be necessary to propose the internal diameter recognition device that a kind of operation is simple, easy to operate, work efficiency is high, production cost is low.
Summary of the invention
The object of the present invention is to provide a kind of internal diameter recognition device solving the problems of the technologies described above, comprising:
Transmission channel, for transmitting annular workpieces;
Cylinder, is arranged at described transmission channel outlet, for obtaining annular workpieces;
Sensor, is arranged at the both sides of described cylinder, for detection of the classification of workpiece;
It is characterized in that, described main body is flexible to be arranged, and stretches out pickup, and retraction discharges workpiece, described cylinder upper and lower part diameter difference, and described upper diameter is less than described lower diameter.
As a further improvement on the present invention, cylinder lower area described in described sensor sensing.
As a further improvement on the present invention, described sensor is optical fiber correlation sensor.
As a further improvement on the present invention, described cylinder stretches out the pickup of described transmission channel face, and transmission channel face discharges workpiece described in indentation.
Internal diameter recognition device of the present invention utilizes pickup cylinder upper and lower part that different diameters is set, and large workpiece falls into lower diameter, and little workpiece will be enclosed within upper diameter, then by sensor, thereby the type of identification workpiece.Its operation is simple, and work efficiency is high, and design cost is low.
Brief description of the drawings
Fig. 1 is internal diameter recognition device structural representation of the present invention.
Embodiment
Describe the present invention below with reference to embodiment shown in the drawings.But these embodiments do not limit the present invention, the conversion in structure, method or function that those of ordinary skill in the art makes according to these embodiments is all included in protection scope of the present invention.
Shown in please refer to the drawing 1, be internal diameter recognition device of the present invention, be mainly used in a kind of detection of annular workpiece, comprising: transmission channel 10, for transmitting annular workpieces; Cylinder 20, is arranged at described transmission channel 10 and exports, for obtaining annular workpieces; Sensor 30, is arranged at the both sides of described cylinder 20, for detection of the classification of workpiece, and in the present invention, the optical fiber correlation sensor 30 that sensor 30 adopts.
Wherein, these cylinder 20 upper and lower part diameter differences, described top 21 diameters are less than described bottom 23 diameters.The flexible setting of described cylinder 20, under normal circumstances, these cylinder 20 retraction worktable.When there being workpiece to be transported to this cylinder 20 positions by transmission channel 10,20 of cylinders stretch out and obtain workpiece, and workpiece is enclosed within on this cylinder 20, and then, optical fiber correlation sensor 30 detects, thereby judges its workpiece type.Particularly, optical fiber correlation sensor 30, be arranged on cylinder 20 both sides, its correlation region comprises the bottom 23 of trunk portion, can reduce like this sensor size, without covering whole cylinder 20, reach same detection effect, after cylinder 20 stretches out, detected in the bottom 23 of cylinder 20 and had the words of annular workpieces for large workpiece, if workpiece do not detected, it is so little workpiece.
After detection, cylinder 20 retractions discharge workpiece, and according to testing result difference, workpiece enters corresponding next process.
Be to be understood that, although this instructions is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should make instructions as a whole, technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
Listed a series of detailed description is above only illustrating for feasibility embodiment of the present invention; they are not in order to limit the scope of the invention, all do not depart from the equivalent embodiment that skill spirit of the present invention does or change and all should be included in protection scope of the present invention within.
