Abstract
This invention relates to one mechanical device, especially a length measurement device. The purpose of this invention is to solve the problem of the diffuse reflectance of receiving light existed in the original technology, it supplies a measurement device of pipe length with high accuracy and be more reliable, including the launch photoelectric box and receiving box photoelectric paired placed. The photoelectric box includes the box body with a removable lid, the photocell fixed in the internal box by the installation frame and the long and narrow rectangular aperture hole, which is covered with aperture, located in the end position of Corresponding photocell light emission. This pipe length measurement devices can avoids the negative impact on the accuracy of testing caused by the stray light, also improves the accuracy and reliability.
Description
Technical field
The present invention relates to a kind of mechanical hook-up, especially a kind of length-measuring appliance.
Background technology
Steel pipe is surveyed long use in pairs (emission is accepted) photoelectric tube segmentation more and is installed in the fixed position at present, and steel pipe moves and obstructs the light, and the photoelectric tube spacing reflects steel pipe length.Because it is longer to accept to get the little hole length of light before the photoelectric tube, the diffuse reflection that produces light impacts measuring accuracy and reliability.
Summary of the invention
The objective of the invention is provides a kind of measuring accuracy higher, more reliable device for measuring length of steel pipe in order to overcome irreflexive problem of reception light in original technology.
For realizing purpose of the present invention, this instructions provides a kind of device for measuring length of steel pipe, comprises the emission photoelectricity box and reception photoelectricity box of paired placement.The photoelectricity box comprises the box body that has detachable lid, is fixed on the photoelectric tube of box body inside by erecting frame, in the emission of photoelectric tube or receive the aperture that has narrow and long rectangular on the box body endface position on the light ray propagation approach, is coated with the diaphragm sheet on the aperture.
In each photoelectricity box a plurality of photoelectric tubes are installed, corresponding also have a plurality of apertures and a diaphragm sheet.
Device for measuring length of steel pipe provided by the invention, in emission, receiving the interior installing space of photoelectricity box is the photoelectric tube of L, when steel pipe moves, when blocking n photoelectric tube, just illustrates that steel pipe is n * L length.On the photoelectricity box, certain distance is installed a diaphragm sheet before receiving photoelectric tube, is screwed.The hole shape that is in the light is a narrow and long rectangular, increases the light-receiving energy.Avoid the influence of parasitic light, improved measuring accuracy, improved reliability measuring accuracy.
Purpose of the present invention, feature and advantage will be in conjunction with the embodiments, are further described with reference to accompanying drawing.
Description of drawings
Fig. 1 is a photoelectricity box inner structure synoptic diagram of the present invention;
Among the figure: 1 is box body, and 2 is lid, and 3 is the diaphragm sheet, and 4 is photoelectric tube, and 5 is erecting frame.
Embodiment
With reference to last figure, provide following embodiment.To help to understand the present invention by embodiment, but not limit content of the present invention.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
Embodiment: this device for measuring length of steel pipe comprises the emission photoelectricity box of paired placement and receives the photoelectricity box.The photoelectricity box comprises the box body 1 that has detachable lid 2, be fixed on the photoelectric tube 4 of box body 1 inside by erecting frame 5, in the emission of photoelectric tube 4 or receive the aperture that has narrow and long rectangular on box body 1 endface position on the light ray propagation approach, be coated with diaphragm sheet 3 on the aperture.
A plurality of photoelectric tubes 4 are installed in each photoelectricity box, and corresponding also have a plurality of apertures and a diaphragm sheet 3.
