The invention relates to the technical field of cutting equipment, and discloses cutting equipment for precise mechanical part manufacturing and a using method thereof.The cutting equipment comprises a working shell, the top of the working shell is fixedly connected with a square ring plate, a workpiece sleeve is placed on the outer wall of the top end of a special-shaped shell frame, a first electric telescopic rod is started, the first electric telescopic rod drives a square plate to descend, and the square plate is driven by the first electric telescopic rod to descend; the square plate drives a forward and reverse motor to descend, the forward and reverse motor drives a rotating shaft to descend, the rotating shaft drives a cross-shaped sleeve to descend, and when the cross-shaped sleeve moves into a cross-shaped groove in the inner wall of the special-shaped shell frame, the forward and reverse motor is started, the forward and reverse motor drives the rotating shaft to rotate, and the rotating shaft drives the cross-shaped sleeve to rotate; the cross sleeve drives the special-shaped shell frame to rotate, the special-shaped shell frame drives the workpiece sleeve to rotate, meanwhile, the second electric telescopic rod is started, the second electric telescopic rod drives the cutter to move upwards at a constant speed, the cutter makes contact with the side wall of the workpiece sleeve in the upward moving process, and therefore thread cutting work is conducted on the outer wall of the workpiece sleeve.

The invention discloses a welding combined type spiral bevel gear milling cutter and a welding tool, and relates to the technical field of welding. The milling cutter comprises a base, a connecting seat is welded to the top of the base, a milling cutter body is welded to the top of the connecting seat, a positioning device is arranged at the top of the base and comprises a first positioning groove, the inner wall of the first positioning groove is formed in the top of the base, and a second positioning groove is formed in the bottom of the connecting seat. A hollow positioning column is clamped to the inner wall of the first positioning groove. Through the arrangement of the positioning device, the first positioning groove, the second positioning groove and the hollow positioning column are matched, the connecting base and the milling cutter body are welded to the base through welding bonding points, the hollow positioning column is clamped into the first positioning groove, and then the second positioning groove of the connecting base is aligned to the hollow positioning column; therefore, the base can be accurately welded together, and local weaknesses or defects such as air connecting holes and cracks are avoided.

The invention discloses an imaging method for an endoscope imaging system and the endoscope imaging system. The method comprises the following steps: receiving a mode switching instruction for switching from a first imaging mode to a second imaging mode; in the second imaging mode, the light source host is controlled to alternately output visible light and exciting light, a visible light signal is obtained when the light source host outputs the visible light, and a fluorescence signal is obtained when the light source host outputs the exciting light; the second imaging mode sequentially comprises a first stage and a second stage, in the first stage, a second visible light signal and a first fluorescence signal are acquired, and only a second visible light video image generated based on the second visible light signal is displayed; and in the second stage, acquiring a third visible light signal and a second fluorescence signal, and displaying a fluorescence video image at least based on the second fluorescence signal. According to the invention, jamming in the mode switching process can be avoided.

The invention discloses cryptocaryon irritans inhibition antigen bigeminy recombinant protein as well as a preparation method and application thereof. The amino acid sequence of the cryptocaryon irritans inhibition antigen bigeminy recombinant protein is as shown in SEQ ID NO: 1. By means of terminator replacement and codon optimization and insertion of the Linker protein of the 15 peptide composed of Gly and Ser between the two activity-inhibiting antigen proteins, the situation that the two activity-inhibiting antigen recombinant proteins possibly interfere with each other in the spatial structure, and the integrity of the antigen epitopes of the two activity-inhibiting antigen recombinant proteins is affected is avoided; the defect that a single inhibition antigen provides immune protection for cryptocaryon irritans infection is overcome. The cryptocaryon irritans inhibition antigen bigeminy recombinant protein can be used for preparing vaccines, medicines or immune preparations for preventing and treating cryptocaryon irritans diseases.
