Description

Technical Field

[0001] The utility model relates to the technical field of direct-reading spectrometers, in particular to a fixture for direct-reading spectrometers of small-diameter steel bar samples. Background Art

[0002] Direct reading spectrometer, also known as OES (Optical Emission Spectrometer), is an atomic emission spectrometer. After World War II, due to the reconstruction of Europe, the market had a huge demand for steel testing, which also promoted the development of related testing instruments. In the 1960s, photoelectric direct reading spectrometers began to develop rapidly with the development of computer technology. Due to the development of computer technology, the development of electronic technology, the miniaturization of electronic computers, the emergence and popularization of microprocessors, and the reduction of costs, in the 1970s, spectral instruments were almost 100% controlled by computers, which not only improved the analysis accuracy and speed, but also realized automatic control of the data processing and analysis process of the analysis results. With the development of computer technology and software technology in the 1980s, direct reading spectrometers developed rapidly.

[0003] However, due to the limitation of the excitation hole diameter of the direct reading spectrometer, the existing vacuum direct reading spectrometer cannot detect rod-shaped samples with a diameter less than 12 mm. In addition, when detecting samples with a diameter of 12-14 mm, argon leakage is prone to occur, resulting in a large deviation in the test results. Therefore, those skilled in the art provide a small-diameter steel bar sample direct reading spectrometer fixture to solve the problems raised in the above background technology. Utility Model Content

[0004] The utility model aims to provide a small-diameter steel bar sample direct-reading spectrometer fixture to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A direct-reading spectrometer fixture for small-diameter steel bar samples comprises a direct-reading spectrometer, a mounting structure and a clamping structure. The fixture is characterized in that a mounting seat is provided at the upper end of the direct-reading spectrometer, a clamping structure is provided at the upper end of the mounting seat, a clamping block is provided at the clamping structure, a mounting structure is provided at the upper end of the clamping block, and a detection groove is provided at the center of the upper end surface of the mounting seat.

[0007] As a further solution of the utility model: an external clamping frame is arranged on the upper end of the mounting seat, an internal clamping frame is arranged on the inner side of the external clamping frame, an annular rack is arranged on the bottom end of the inner wall of the external clamping frame, and slots are arranged at the four vertices of the external clamping frame and the internal clamping frame, clamping blocks are arranged in the slots, racks are arranged on the right side walls of the clamping blocks, and the clamping blocks are movably connected to the slots.

[0008] As a further solution of the utility model: a driving gear is arranged on the right side of the upper left rack, a servo motor is arranged on the upper end of the driving gear, and driven gears are arranged on the other side ends of the racks, a slider is arranged on the right side of the clamping block, a slide groove is arranged on the right side of the card slot, and the slide groove is movably connected to the slider.

[0009] As a further solution of the utility model: the outermost end faces of the clamping blocks are all provided with grooves, and the rightmost end faces of the upper end faces of the clamping blocks are all provided with threaded holes.

[0010] As a further solution of the utility model: the driving gear 7 is meshed with the annular rack 11, the driven gear 5 is meshed with the annular rack 11, the driving gear 7 is meshed with the rack 10, and the driven gear 5 is meshed with the rack 10.

[0011] Compared with the prior art, the beneficial effect of the utility model is as follows: the staff places the rod-shaped sample in the detection groove at the center of the mounting block, and then starts the servo motor, and the servo motor drives the driving gear to rotate. Because the driving gear is meshed with the annular rack, the driven gear is meshed with the annular rack, the driving gear is meshed with the rack, and the driven gear is meshed with the rack. Therefore, when the driving gear rotates, it can drive the annular rack to rotate, as well as the rack on the right side, and the linked clamping block moves toward the center of the circle. The annular rack drives the other three driven gears to rotate, and the driven gear drives the clamping blocks at the upper ends of each corresponding rack to clamp toward the center of the circle at the same time, so that rod-shaped samples of any diameter can be clamped and fixed, and can also be fixed by threading. The holes and grooves cooperate with each other, and the clamping mold at the front end of the clamping block can be replaced. The corresponding clamping plate can be replaced according to the items to be clamped. The utility model is provided with a clamping structure, and four clamping blocks are simultaneously moved toward the center for clamping, so rod-shaped samples of various sizes can be clamped and fixed to prevent the rod-shaped samples from loosening, falling off, and other special situations during the detection, and it is convenient for the staff to operate. The installation structure can be used to replace the clamping plate according to the specific situation, which greatly improves the adaptive force, so that the clamping structure can clamp samples of different shapes and sizes. The utility model relates to a direct-reading spectrometer fixture for small-diameter steel bar sample. The utility model is simple and reasonable in structure design, and is convenient and quick to operate. BRIEF DESCRIPTION OF THE DRAWINGS
