The invention relates to a laser welding method for a repairing penetrating defect of base metal. The method comprises the following steps that S1, the to-be-repaired defect of the base material is pretreated and machined into a groove weld joint with a wide upper portion and a thin lower portion; S2, the width of a weld joint lower groove is determined, if the width of the lower groove is greaterthan the diameter of a welding wire, at least one layer of convex weld welding are conducted on the two sides of the lower groove side by side in the length direction of the weld joint until the width of the lower groove is the same as the diameter of the welding wire, then priming layer welding is conducted on the weld joint between convex welds on the two sides, and if the width is smaller thanor equal to the diameter of the welding wire, the priming layer is directly welded; S3, multiple welding layers are superimposed and welded on the priming layer, a welding layer zone is formed, and the top of a welding layer block is lower than a weld joint upper groove; S4, a repair layer is superimposed and welded on the welding layer block, and the top of the repair layer is higher than the weld joint upper groove; and S5, the repair layer higher than the upper groove is ground, and thus the repair layer is flush with the upper groove.

The invention discloses a rotor and a motor. The rotor comprises a rotor core and a rotor shaft (100), wherein the rotor shaft (100) is sleeved with the rotor core; a convex knurling (110) is arranged in a region, matched with the rotor core, of the rotor shaft (100); and the convex knurling (110) is not parallel to a center line of the rotor shaft (100). The convex knurling (110) is arranged on the rotor shaft (100); and the rotor shaft (100) is matched with the rotor core through the convex knurling (110), so that the defect caused by too high or too low magnitude of interference in the circumference fit process is avoided; the magnitude of interference between the rotor shaft (100) and the rotor core is increased under the premise of not increasing the difficulty that the rotor shaft (100) enters the rotor core; the difficulty of axial relative displacement of the rotor core and the rotor shaft (100) is increased; and falling of the rotor or the phenomenon of a poor test is effectively prevented.

The invention discloses a self-consumption type simple heat preserving cover of a molten iron conveying tank and a use method of the self-consumption type simple heat preserving cover. The self-consumption type simple heat preserving cover is arranged on a container opening of a molten iron container. The heat preserving cover comprises a concave heat preserving assembly. The concave heat preserving assembly is a rotary body with an opening formed in the top, wherein the external diameter of the rotary body is gradually reduced from top to bottom, the concave heat preserving assembly is embedded into the container opening, and comprises an internally-hollow concave metal sheet box, a bottom leak hole is formed in the bottom face of the concave metal sheet box, inverted L-shaped tank opening supporting frames are symmetrically arranged on the end face of the edge of a box opening of the concave metal sheet box, the bottoms of the vertical sections of the tank opening supporting frames are connected with the upper end face of the concave metal sheet box, and the concave metal sheet box is filled with a heat preserving layer. The self-consumption type simple heat preserving cover hasthe advantages that the self-consumption type simple heat preserving cover is simple in structure, convenient to use and excellent in heat preserving performance, materials are cheap and easy to obtain, the cover body structure metal materials are online molten and recovered, molten iron slag is online modified with heat preserving material ash, and the acclimatation capacity is high.

The present invention relates to a method for preparing high-elasticity warm-keeping polyester composite yarn, which uses an oiling equipment, the oiling equipment includes a bottom plate, a mounting plate, an oiling device and a recovery box, and the above-mentioned oiling equipment is used to prepare high-elasticity warm-keeping polyester The specific process of the composite yarn is as follows: spun fiber forming, spun fiber oiling, spun fiber post-processing and winding molding, the oiling device includes a fixed rod, a rotating drum, an auxiliary mechanism, a driving mechanism, an oil storage cylinder, and an oiling sponge sleeve, oil suction column, sliding block, oil baffle, limit tube, connecting rod, moving rod and fixed ring. The invention uses the oiling device to cooperate with the existing traction equipment to complete the oiling work of the primary fiber. During the oiling process, the relative movement between the moving rod and the fixed ring drives the oil absorption column and the limit cylinder to stir the lubricating oil, and at the same time The bonding tightness between the primary fiber and the oiling sponge cover is increased through the auxiliary mechanism to improve the uniformity of oiling.

The invention discloses an exposure platform of an exposure machine. The exposure platform comprises an exposure frame, an objective table, a plurality of elevating units and a light-transmitting plate, wherein the objective table can approach to or keep away from the exposure frame; an accommodating region is formed in the upper surface of the objective table, and is used for putting a substrate and projecting incident light of an exposure light source to the substrate; the elevating units are arranged on the exposure frame; and the light-transmitting plate is combined with a clamp of each elevating unit, and is driven by the elevating units to move towards or away from the accommodating region of the objective table. The light-transmitting plate of the exposure platform disclosed by the invention is fixed to the bottom surface of the exposure frame through the clamps and the elevating units; and when vacuum pumping is carried out in the exposure step of a circuit board manufacture procedure, the light-transmitting plate can be driven by the elevating units, can be fitted to the substrate, and can deform along with the flatness of the substrate, so that the fitting tightness of the light-transmitting plate and the substrate is increased to improve the exposure resolution ratio.
