Description

Technical Field

[0001] The utility model relates to the technical field of pig iron sample preparation tools, and particularly relates to a cylinder fixture for preparing small pieces of pig iron samples. Background Technique

[0002] The preparation of pig iron samples is an important link in the metallurgical analysis and quality control process. The aim is to process the pig iron samples to meet the standards of laboratory analysis, so as to accurately determine the contents of various elements in the pig iron. Determine the contents of main elements (such as carbon, silicon, manganese, phosphorus, sulfur, etc.) and trace elements in the pig iron. Ensure that the quality of the pig iron meets the production standards and customer requirements.

[0003] At present, the convenient method for preparing pig iron samples is to place the pig iron samples on a drilling machine to directly drill for iron filings. The hot-pressed iron block is in a small block size of about 10*5 cm. When drilling the sample to obtain drill chips, the existing fixtures of the drilling machine cannot fix it. When drilling the sample, the hot-pressed iron block is easy to rotate and fly out, posing a safety hazard. And the drill chips fly scattered along with the rotation of the hot-pressed iron block and are scattered on the operating table and cannot be collected and used, affecting the sample inspection.

[0004] Therefore, there is an urgent need to design a cylinder fixture for preparing small pieces of pig iron samples to solve the problems of ineffective fixation and iron filing dispersion in the existing pig iron sample preparation process. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a cylinder fixture for preparing small pieces of pig iron samples.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a cylinder fixture for preparing small pieces of pig iron samples, including a fixture cylinder and a clamping plate. The clamping plate includes a movable clamping plate and a fixed clamping plate. The movable clamping plate is installed on the cylinder rod of the fixture cylinder. The fixture cylinder and the fixed clamping plate are both installed on the drilling machine workbench. The fixture cylinder controls the movement of the movable clamping plate to cooperate with the fixed clamping plate to clamp the pig iron sample. A shielding plate is installed on the upper part of the fixed clamping plate.

[0007] Specifically, a solenoid valve is installed on the air supply pipeline of the fixture cylinder. The solenoid valve is electrically connected to a middle relay. The middle relay is electrically connected to an emergency switch and a foot switch. The foot switch controls the on-off of the solenoid valve. The solenoid valve controls the on-off of the air supply pipeline and further controls the operation of the fixture cylinder.

[0008] Specifically, the cylinder body of the fixture cylinder is installed on a cylinder mounting plate. The cylinder mounting plate is fixed on the drilling machine workbench. A through hole is provided in the middle of the cylinder mounting plate, and the cylinder rod of the fixture cylinder passes through the through hole.

[0009] Specifically, a moving clamping plate is installed at the end of the cylinder rod of the clamping cylinder. Limiting through holes are provided on both sides of the moving clamping plate. A smooth shaft slides through the limiting through holes, and both ends of the smooth shaft are respectively installed on the cylinder mounting plate and the fixed clamping plate through bolts.

[0010] Specifically, a shielding plate is installed on the upper part of the fixed clamping plate through bolts. A drill rod limiting hole is provided in the middle of the shielding plate. The center of the drill rod limiting hole is directly opposite to the drill rod of the drilling machine. The drill rod of the drilling machine passes through the drill rod limiting hole to drill and sample the pig iron sample.

[0011] Specifically, clamping teeth plates are installed on the opposite sides of the moving clamping plate and the fixed clamping plate.

[0012] The utility model has the following beneficial effects:
