This invention discloses a detachable lifting clamp fixture for ships. It includes a connecting assembly, a driving assembly, and a suspension assembly. The connecting assembly includes a clamping member and a top support member. The clamping member can clamp and fix the web of a pre-shaped profile, and the top support member can abut against the panel of the pre-shaped profile from top to bottom. The driving assembly is connected to the connecting assembly to drive the connecting assembly to clamp and release the web. The suspension assembly is connected to the connecting assembly and is used to install the lifting clamp. Through the clamping member and the top support member, the pre-shaped profile can be detachably fixed in a clamping manner, and the lifting weight can be applied to both the web and the panel simultaneously. Compared with welding the lifting clamp, this avoids welding work, improves lifting efficiency, reduces lifting costs, and reduces damage to the hull structure. Furthermore, by distributing the weight, it reduces the risk of deformation and damage to the hull structure, especially the panel of the pre-shaped profile.

The application discloses a kind of production device of aluminum-clad door and window, it is related to aluminum-clad door and window production technical field, including clamping box, the inside of clamping box is equipped with clamping chamber, the inside welding of clamping chamber is equipped with guide pipe, the inside sliding connection of guide pipe is equipped with guide plate, the side end surface of guide plate is welded with clamping plate, the side end surface of clamping plate is welded with reset rod, the outside of reset rod is sleeved with reset spring, the unified height of the present application is fixed by wood board and aluminum profile, then control initiative roll rotation, the two sides of wood board and aluminum profile are all in unified vertical plane, so that wood board and aluminum profile are all fixed in same position, then wood board and aluminum profile can be simultaneously cut from the same angle by cutting edge, so that the riveting of each side aluminum profile and wood board is facilitated, and all wood board and aluminum profile are cut into same length specification, so that wood board and aluminum profile can be quickly adhered and formed once, without secondary processing.

The invention relates to a pipe annular abrasive belt grinding device which comprises a mechanical arm, a connecting device arranged on the mechanical arm and an abrasive belt and further comprises a driving device, a tensioning device and a grinding frame which are arranged on the connecting device, and the grinding frame is provided with a grinding groove. The moving devices are symmetrically arranged on the two sides of the grinding groove. The pressing device is arranged on the moving device; the grinding roller is rotationally arranged on the pressing device; the auxiliary rolling wheels are rotationally arranged on the pressing device and symmetrically located on the two sides of the grinding rolling wheel. The gap bridge roller is rotationally arranged on the polishing frame and the connecting device; the abrasive belt is movably arranged on the driving device, the tensioning device, the grinding roller and the gap bridge roller in a sleeving mode, the pressing device symmetrically presses the abrasive belt on the outer circle face of the pipe through the grinding roller, and the auxiliary roller is used for controlling the grinding diameter. According to the device, the two sides of the pipe are symmetrically ground at the same time, the grinding efficiency is greatly improved, meanwhile, the grinding size is accurately controlled through cooperation of the positioning wheel and the pressing device, and the grinding quality is high.

This utility model discloses a protective fixture for impregnating a new energy flat wire oil-cooled motor. It includes a motor stator winding, a lower pressure plate at the bottom of the stator winding, an impregnation bracket at the bottom of the lower pressure plate, a sealing barrel around the stator winding, a lower sealing gasket between the bottom of the sealing barrel and the lower pressure plate, and an upper pressure plate at the top of the stator winding, with an upper sealing gasket between the top of the sealing barrel and the upper pressure plate. By using the upper and lower sealing gaskets, this fixture, when fully immersed in insulating varnish, forms a completely reliable sealed cavity on the stator's outer surface, effectively preventing the entry of insulating varnish. This ensures that no insulating varnish penetrates during the impregnation process, and the stator's outer surface remains clean after curing. This avoids oil cooling blockage and the need for subsequent polishing of the insulating varnish on the stator's oil circuit area, protecting the stator and ensuring that motor performance is not affected.

The invention provides a waterproof top cover for a prefabricated cabin, and belongs to the technical field of power equipment structures, and the waterproof top cover comprises a first top plate, an internal rainproof beam arranged at the bottom of the first top plate, and a fixing assembly mounted at the bottom of the internal rainproof beam. The split type top plate combination is matched with the precise bending butt joint mechanism, the welding workload is greatly reduced while the structural strength is guaranteed, the problems of large-area welding seam polishing and rusting are solved, reliable sealing between modules is achieved through the butt joint bending clamping structure, the defect of water seepage of joints of a traditional modular top cover is overcome, and the service life of the modular top cover is prolonged. According to the integrally-designed water dripping edge system, a traditional welding or screw fixing mode is replaced with an innovative bending forming technology, the installation procedure is simplified, the protection grade is improved, the overall weight is reduced through the optimized structural layout, transportation and hoisting operation is facilitated, and the production cost is reduced while the production efficiency is improved. And the waterproof performance and the installation convenience of the product are improved.
