The invention provides an adjustable door protective plate handle. The adjustable door protective plate handle is close to a door protective plate body of a vehicle and is provided with a handle body and a connecting supporting mechanism for supporting the handle body, and when the handle body is operated by external force, the handle body achieves translation supported by the connecting supporting mechanism; the adjustable door protective plate handle further comprises a position locking mechanism arranged between the handle body and the vehicle to lock the translation position in the handle body translation process. According to the adjustable door protective plate handle, since the connecting supporting mechanism is adopted to support the handle body to make the handle body generate the translation when the handle body is operated by the external force, the handle body is locked through the locking mechanism in the translation path, the position adjustment of the handle body is achieved, so that the handle body meets different position requirements of the handle body, and the comfort during the use of the handle body is effectively improved.

Disclosed are a high-strength-plasticity nano / submicron grain cold-rolled 304 stainless steel strip and a preparation method therefor, belonging to the field of manufacturing cold-rolled austenitic stainless steel strips. The stainless steel strip has the following chemical ingredients in weight percentages: C < 0.08%, Si < 0.80%, Mn < 2.0%, Cr 17%-20%, Ni 8%-10%, and the balance being Fe, trace microalloy elements Mo, Nb and V, and other inevitable impurities. In the present invention, by means of the integrated control of hot-rolling- and cold-rolling-annealing, a high-strength-plasticity nano / submicron grain cold-rolled 304 stainless steel strip finished product is obtained, wherein the microstructure of the finished product steel is a multiscale nano / submicron grain austenite structure composed of ultra-fine grains with a grain size of 150-500 nm and coarse recrystallized austenite grains, a part of which has a grain size of larger than 1 μm. The high-strength-plasticity nano / submicron grain cold-rolled 304 stainless steel strip has excellent strong plasticity matching, a yield strength of ≥ 800 MPa, a tensile strength of ≥ 900 MPa, a total elongation of ≥ 40 %, and a thickness specification covering 0.3-1 mm.

The invention provides a method for conducting assembly welding of a modular steel frame through rotary devices. The method for conducting assembly welding of the modular steel frame through the rotary devices comprises the following steps that (1) the two rotary devices are arranged at the two corresponding ends in the length direction of the modular steel frame separately, wherein each rotary device is composed of a lateral supporting frame part, an electric wheel frame part and a fixed connecting support part; (2) the modular steel frame is hoisted and connected to the rotary devices, and the rotary devices are fixedly connected with modular corner pieces at the two ends of the modular steel frame; (3) after connection of the modular steel frame, a driving wheel is driven by a motor and transmission piece to rotate together with a round wheel track and the modular steel frame, and assembly welding is conducted after components needing to be assembly-welded to different positions of the modular steel frame are rotated to a worker operating position; and (4) after all the components are assembly-welded, the modular steel frame obtained after assembly welding is separated from the rotary devices, and thus assembly welding of the modular steel frame is completed. According to the method for conducting assembly welding of the modular steel frame through the rotary devices, the operating process is simple, the assembly welding efficiency is high, various operation risks are lowered, and the assembly welding quality is ensured.

The invention provides an equipment control component position adjusting device applied to the technical field of mechanical equipment control components. The device body (1) of the position adjusting device is provided with an equipment control component (2). The fixing component (3) of the device body is provided with a slide component (4) which can slide relative to the fixing component (3). The slide component (4) is provided with a rack movement plate (6) equipped with multiple clamping grooves (5). The fixing component (3) is also provided with a fixing plate (7). The fixing plate (7) is provided with a locking top pin (8) which flexibly penetrates through the fixing plate (7). The locking top pin (8) is arranged to be a structure which can be clamped in the clamping grooves (5) of the rack movement plate (6). According to the device, position adjustment of the equipment control component can be conveniently and rapidly realized, and the position of the device body can be locked after movement of the position so that the requirement for different positions of the device body due to difference of arm length of different groups of people can be met.

The invention relates to the technical field of vehicle tooling, in particular to a positioning welding device. The positioning welding device comprises a supporting base and a pneumatic control unit connected with the supporting base. One side of the supporting base is provided with at least one spot welding plate. One side of the supporting base corresponding to the spot welding plates is connected with positioning welding units, and the number of the positioning welding units matches with that of the spot welding plates. The positioning welding units are connected with the pneumatic control unit and are driven by the same. According to the positioning welding device, the pneumatic control unit drives the positioning welding units at different positions in a switchable manner to weld a wheel housing support, so that stability, uniformity and controllability of welding the wheel housing support can be guaranteed effectively, requirements of different positions of welding the wheel housing support of different vehicle models can be met, and vehicle assembling efficiency is improved.
