By means of the device and method, four to-be-machined stations of the guide vane can be subjected to continuous grinding.

The invention discloses an automobile top cover and a top cover rear cross beam nesting drawing forming method and die. According to the method, the top cover and a top cover rear cross beam forming cavity are nested in a drawing molding die, so that the top cover and the top cover rear cross beam are simultaneously formed in one stamping process. According to the method, the top cover and the topcover rear cross beam can be nested together to be produced, die toolings can be saved, and stamping production batches are reduced.

The invention discloses an anti-explosion combination wrench with replaceable bayonets and relates to an anti-explosion wrench. An opening end (5) and a plum blossom end (9) are respectively arranged at two ends of a handle (6). The opening end (5) is provided with a jack (4). Raised lines (2) arranged on outer walls of two sides of a U-shaped connector clip (3) are connected with grooves (15) of the jack (4) in an inserting mode. A plurality of bayonets (1) of the U-shaped connector clip (3) are respectively in various sizes. The plum blossom end (9) is provided with a placing inlet (12). The periphery surface of an insertion cover piece (14) is connected with the placing inlet (12) in an inserting mode. A plurality of plum-blossom-shaped covering ports (8) of the insertion cover piece (14) are respectively in various sizes. Aluminium bronze or beryllium bronze is adopted as manufacture material quality. By the adoption of the plurality of the bayonets, in various sizes, of the U-shaped connector clip and the plurality of cover ports, in various sizes, of the insertion cover piece, the fact that the tool quantity is effectively reduced in operation is achieved.

A tool for overall assembling welding of an engine outer ring assembly comprises a base plate, a positioning ring, a pressing plate, a main expansion block, an auxiliary expansion block, a pressing cover, a screw rod, a guide plate, a spring, a rubber mat, a locking nut, an end cover nut, a shoulder nut, a guide column, a cone, a pipe connecting nozzle, an air guide pipe and an air nozzle. By means of the tool, two circular welding seams of the engine outer ring assembly and three groups of mounting seat welding seams can be integrated in one device for limiting machining, so that the number of tools required in the machining process is greatly reduced, and the machining cost is greatly reduced; meanwhile, one-time clamping machining is achieved, error accumulation caused by repeated clamping is avoided, clamping positioning is accurate, rapid and stable, dismounting is convenient and rapid, meanwhile, the error prevention effect is achieved, the conditions of wrong mounting, neglected mounting and the like are avoided, and the machining efficiency is greatly improved; and in addition, the device can achieve manual welding and automatic welding expansion, and meanwhile the multi-application requirements of products are met.

The invention discloses a quick joint transfer box with current display. The box includes a casing and a cover, wherein one end of the cover is hinged with a top surface of the casing through a hinge,the other end is in locking connection with a front surface of the casing through a buckle, a bottom surface in the casing is provided with multiple guide rails, each guide rail is in sliding connection with a sliding seat, each sliding seat is provided with an adapter support, each adapter support is provided with a first through hole, each first through hole is internally provided with a flangedisc and an adapter sleeve which penetrates through the flange disc and is in fixed connection with the flange disc, a tail end of each adapter sleeve is sleeved with a clamping head, each clamping head is internally plugged with a wire middle end sleeve, and the wire middle end sleeve extends from a back surface of the casing to an outer part of the casing.
