Abstract
The invention relates to a straight pipe inspection device, which comprises a placing shelf on which a straight pipe to be inspected is placed, a light source producing unit and a facula collecting plate, wherein the light source producing unit and the light spot collecting plate are respectively arranged at two ends of the straight pipe in an opposite manner. The straight pipe inspection device inspects the straight pipe by utilizing the rectilinear propagation characteristic of light, the efficiency is high, and the error is small.
Description
Technical field
The present invention relates to a kind of straight tube verifying attachment.
Background technology
The check work of existing straight tube has artificial naked eyes to carry out usually, thereby guarantees product quality in order to crooked straight tube is carried out to straightening work.The desk checking error is large and work efficiency is lower, makes in the product that dispatches from the factory and easily mixes unacceptable product is arranged, and therefore needs a kind of device that can automatically test to straight tube.
Summary of the invention
The object of the invention is to address the above problem, and a kind of straight tube verifying attachment is provided, and specifically by following technical scheme, is realized.
A kind of straight tube verifying attachment, is characterized in that, comprises the rack, light source generation and the hot spot collection plate that are placed with straight tube to be tested, and described light source generation and hot spot collection plate are relative as for the two ends of straight tube and both respectively.
Described straight tube verifying attachment, it further designs and is, several photoresistance of matrix distribution on described hot spot collection plate.
Described straight tube verifying attachment, it further designs and is, and described hot spot collection plate also is connected with a data processor.
The present invention tests to straight tube in the rectilinear propagation characteristic of utilizing light, and efficiency is higher, and error is less.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with Figure of description and specific embodiment, the present invention is further described.
This straight tube verifying attachment, comprise the rack 1, light source generation 2 and the hot spot collection plate 3 that are placed with straight tube 5 to be tested, and light source generation 2 and hot spot collection plate 3 are relative as for the two ends of straight tube and both respectively.Several photoresistance of matrix distribution on hot spot collection plate 3.The hot spot collection plate also is connected with a data processor 4.
According to the resistance of each photoresistance on the hot spot collection plate, whether change and gather corresponding electric signal, compare with due electric signal under the status of criterion, whether meet the requirements thereby know straight tube.
The present invention tests to straight tube in the rectilinear propagation characteristic of utilizing light, and efficiency is higher, and error is less.
