The invention discloses an assembling clamp of an isolating valve vane. The assembling clamp comprises a bottom plate, wherein a straight guide rail is mounted on the bottom plate; a pair of sliding seats is arranged on the guide rail; a shaft rod is arranged on each sliding seat; the axes of the two shaft rods are located in the same straight line; a pair of rotating arms which rotates around the shaft rod is mounted on each shaft rod; a positioning hole is formed in the other end, far away from the shaft rod, of each rotating arm; the distances between the central lines of the positioning holes of the rotating arms and the axes of the shaft rods are identical; limit pieces which limit the central lines of the positioning holes of the rotating arms at the same horizontal height are arranged on the sliding seats or the bottom plate; a pre-compression spring is arranged between each pair of rotating arms; radial through holes are formed in the shaft rods; a guide shaft penetrates through the through holes of the two shaft rods. After the assembling clamp of the isolating valve vane is adopted for assembling the isolating valve vane, rotating shafts of shaft lugs penetrate through the positioning holes, since the central lines of the four positioning holes are located at the same straight line, the four rotating shafts are coaxial, the mounting positions of the shaft lugs can be rapidly and precisely positioned through adjusting the positions of the sliding seats, the operation is simple, and the work efficiency is high.

The invention discloses a fork strip front wheel concentric welding device. A first positioning plate is located on the left side of the front end of the top of a rack and in welded connection with the rack. A second positioning plate is located on the right side of the front end of the top of the rack and in welded connection with the rack. A first positioning hole is located in the upper end of the first positioning plate and is in the shape of a circular through hole. A second positioning hole is located in the upper end of the second positioning plate and is in the shape of a circular through hole. The first positioning hole and the second positioning hole are in the same axial line. A hanging ring is located at the front end of the right side of the rack and is in welded connection with the rack. A concentric bar is located on the inner side of the hanging ring and movably connected with the hanging ring. According to the fork strip front wheel concentric welding device, the structure is ingenious, the functions are powerful, the wheel plate welding concentricity is improved, and forklift operation quality is ensured.
