The utility model discloses a motor rotor shaft turning clamp that can be self-adaptive and tightly hold and flexibly position, relates to the field of machining, and is composed of Morse taper, external thread connecting shaft, spring collet, threaded sleeve and adjusting sleeve and other components for connecting with the main shaft of machine tool. The sliding cavity of the front end of the external thread connecting shaft is provided with a sliding sleeve and a telescopic spring, and the sliding sleeve is fixedly connected with the spring collet. The sleeve sleeve of the front end of the threaded sleeve is sleeved outside the spring collet, and the inner wall of the front end is provided with a conical surface that is matched with the conical head of the spring collet. The adjusting sleeve is connected with the threaded sleeve through threads, and can drive the limiting sleeve to push the spring collet to move. During use, rotating the adjusting sleeve makes the spring collet move backward, and the spring collet is tightened under the action of the conical surface, the rotor shaft is self-adaptively and tightly held, and the telescopic spring realizes flexible positioning and compensates for the axial and angular deviation. The clamp can automatically adapt to the rotor shaft with a diameter tolerance within a certain range, has high self-centering precision, is suitable for high-precision turning machining of conventional rotor shafts, and has simple structure and convenient maintenance.

The application relates to the technical field of surface strengthening treatment, in particular to a surface strengthening treatment equipment and process for a laser cutting machine bed, which comprises a plasma spraying device and two electric sliding tables fixedly installed at one end of the plasma spraying device, a side plugging mechanism and a plurality of uniformly distributed plugging strips are arranged on the side, away from the plasma spraying device, of the mounting seat, an unlocking mechanism is arranged in the mounting seat, an upper plugging plate is movably arranged in the mounting seat, and a fixing mechanism is arranged at the two ends of the support. The surface strengthening treatment of the linear guide rail sliding block can adopt the process of plasma spraying and thermal spraying powder and wire material, the linear guide rail sliding block is automatically shielded by the mutual cooperation between the upper plugging plate, the side plugging plate, the plurality of plugging strips and the mounting seat in the device, and the ball circulating track, the sealing groove, the end cover interface and the threaded hole at the top of the linear guide rail sliding block are automatically shielded.

The application discloses a method for analyzing phases of iron in ores, and belongs to the technical field of mineral analysis. The method comprises the following steps: after magnetic separation of an ore sample, performing iron valence state analysis on a magnetic product, and distinguishing a magnetic iron phase, a pseudo hematite phase and a magnetic intergrowth phase based on the deviation degree of the ratio of divalent iron to trivalent iron from the theoretical ratio of magnetite; sequentially performing iron carbonate phase selective leaching-oxidation post-treatment, hematite-limonite phase reduction-inhibition synergistic selective dissolution, iron sulfide phase liquid phase complexation-solid phase charring step-by-step extraction and iron silicate phase alkali fusion digestion on a non-magnetic product; and finally, performing plasma atomic emission spectrometry on each phase to-be-measured solution and total iron digestion liquid, and calculating the iron content of each phase. The application solves the key problems in traditional iron phase analysis, such as incomplete classification of magnetic iron, poor selectivity of non-magnetic phase and insufficient wide use.

This utility model discloses a cutting device for inductor coil production. The cutting mechanism includes a mounting plate with through holes on both the front and back sides. Two through holes are provided, and the two through holes are located on the same vertical line. Positioning recesses are provided on both sides of the through holes on the surface of the mounting plate. Each positioning recess extends vertically, and its lower end extends to the bottom surface of the mounting plate. A blade is provided on one side of the mounting plate, and an anvil is provided on the other side. The thickness of the anvil is greater than the thickness of the blade. Clamping grooves in the sliders on both sides are used to insert and fix the mounting plate. When manually cutting the coil, the blade and anvil are respectively placed on both sides of the coil, thus forming a single-blade clamp structure. Therefore, only one side of the blade needs to be pushed to cut the coil, which is more labor-saving.

The invention relates to composite metal fuel powder which comprises metal fuel particles, a metal oxide layer and an organosilane layer, the metal oxide layer is located on the surfaces of the metal fuel particles, and the organosilane layer is located on the surface of the metal oxide layer; the organosilane layer includes an organosilane, and the organosilane includes a hydrophobic hydrocarbyl chain. According to the composite metal fuel powder, the metal oxide layer can cut off a channel for water and oxygen to diffuse and permeate into the metal fuel particles, the organosilane layer with the hydrophobic alkyl chain enables water molecules to be difficult to wet and adsorb on the surfaces of the metal fuel particles, and the hydrophobic capacity of the metal fuel powder is improved; the metal oxide layer and the organosilane layer work synergistically, so that the metal fuel powder has certain environmental inertia, the storage safety is improved, and the safety risks of nature, gas production or heating and the like are reduced.
