Abstract

A clamp for detecting small-specification steel by matching with a spark spectrometer comprises a sample placing hole, a screw hole, a jacking bolt, a clamp main body and a positioning table; the steel sample placed in the sample placing hole is fixedly connected with the sample placing hole and the clamp main body through the puller bolt when the section to be excited of the steel sample and the section of the lower part of the clamp main body are on the same horizontal plane; the fixture main body and the steel sample connecting body are positioned on the clamping seat of the excitation table of the photoelectric direct-reading spectrometer through the positioning table. The sample placing hole and the exciting electrode hole of the photoelectric direct-reading spectrometer are concentric, namely the center point of the steel sample and the center point of the exciting electrode of the photoelectric direct-reading spectrometer are aligned. The advantages are that: the excitation point of each sample can be ensured to be at the center, the possibility of exciting to the edge of the sample or even the clamp body is avoided, and the accuracy of analysis data is ensured.

Description

Clamp for detecting small-specification steel by matching with spark spectrometer

The technical field is as follows:

the utility model relates to a steel chemistry detects technical field, especially relates to a cooperation spark spectrum appearance detects anchor clamps of small dimension steel.

Background art:

in the prior art, a spark spectrometer is used for completing chemical component analysis of steel and molten steel in the technical field of metal chemical analysis, a sample is required to be placed on an excitation hole during analysis, the sample completely covers the excitation hole, the diameter of the excitation hole of the device is 12mm, the excitation hole cannot be completely covered by a steel sample with the diameter smaller than or equal to the diameter of the hole, and a component detection task is required to be completed by means of a small sample clamp. The maximum diameter of the small sample clamp of the equipment is only 12mm, but for ribbed deformed steel bar with the diameter of 12mm, the surface is not smooth, spiral grains exist, the existing small sample clamp cannot be placed into the equipment for analysis, and meanwhile, the prestressed steel strand 82B with the diameter of 12.5mm cannot be detected. Therefore, a clamp matched with a spark spectrometer for detecting a steel sample with a small specification of phi 12-13mm needs to be developed.

The utility model has the following contents:

the utility model aims at overcoming the not enough of prior art, provide one kind and can solve small dimension steel phi 12mm ribbed screw steel and phi 12.5mm prestressing force steel strand detection difficult problem's cooperation spark spectrum appearance detects the anchor clamps of small dimension steel.

The utility model discloses a solve the technical scheme that above-mentioned problem provided and be:

the utility model provides a cooperation spark spectrum appearance detects anchor clamps of small-specification steel which characterized in that: comprises a sample placing hole, a screw hole, a puller bolt, a clamp main body and a positioning table; the steel sample placed in the sample placing hole is fixedly connected with the sample placing hole and the clamp main body through the puller bolt on the screw hole when the section to be excited of the steel sample and the section of the lower part of the clamp main body are on the same horizontal plane; and the positioning table is used for positioning the clamp main body and the connecting body of the steel sample on the clamping seat of the excitation table of the photoelectric direct-reading spectrometer.

Above-mentioned anchor clamps that cooperation spark spectrum appearance detected small-size steel, location platform and spark spectrum appearance cassette are strictly fixed a position, ensure that the sample is placed the hole and is concentric with the photoelectric direct reading spectrum appearance excitation electrode hole, and steel sample central point is promptly with the centering of photoelectric direct reading spectrum appearance excitation electrode central point.

Above-mentioned anchor clamps that cooperate spark spectrometer to detect small-size steel, sample are placed the hole aperture and are set up to phi 13 mm.

The utility model has the advantages that: because the excitation electrode of the direct-reading spectrometer is already positioned at the center of the excitation hole, the clamp is placed on the excitation table, the center position of the sample hole vertically placed in the clamp main body is adjusted until the clamp main body is concentric with the excitation electrode hole, so that the excitation point of each sample can be ensured to be positioned at the center of the clamp main body, the possibility of exciting the edge of the sample or even the clamp main body is avoided, and the accuracy of analyzing data is ensured. The problem of the direct-reading spectrometer analysis diameter 12mm screw thread steel sample is solved, the problem of phi 12.5mm82B special specification detection is solved, and the specification range of the direct-reading spectrometer analysis steel sample is expanded.
