The invention discloses a precision machining method for an arc-shaped airfoil, and belongs to the technical field of airfoil machining. According to the structure and the material of the airfoil to be formed, a clamping tool is designed and machined, and the tool is used for clamping and supporting the airfoil. And the airfoil and the clamping tool are subjected to trial assembly, and the clamping tool profile which is not tightly matched is optimized according to the trial assembly result. The airfoil is clamped on a clamping tool, then the tool is fixed on a jaw vice, finally the jaw vice is fixed on a cradle of a cradle type five-axis machining center, the rotation and swing directions of the cradle and a turntable are set according to the airfoil structure and process requirements when various sizes are machined, and the airfoil is precisely machined. According to the method for clamping through the tool clamp, the problem that clamping is difficult due to the fact that the outer molded surface of an arc-shaped airfoil product is irregular is solved, after the airfoil and the tool are clamped and fastened, the overall rigidity is high, all molded surfaces are convenient and fast to machine, and the machining precision of the airfoil is greatly improved.

The utility model relates to processing fixture technical field, concretely is a linear guide vice sliding block with processing fixture, the utility model discloses through the fixed insertion of magnetic attraction base on the inner wall of fixed groove, opens the switch of control panel simultaneously, to make the control panel control electric control magnet power generation magnetism, and then make electric control magnet to magnetic attraction base carries out magnetic adsorption, make the fixed more stable of clamping assembly, through the guide rail sliding block and press to the contact sensor and produce electric signal conduction to control panel, when reaching the set value, make control panel control biaxial drive motor and run, will make biaxial drive motor drive shaft respectively drive both sides screw rod and run, and then make screw rod through screw connection drive screw connection block and rotate, make screw connection block drive clamping bottom plate and move to the inboard, will make clamping bottom plate drive limit sliding block and move on the inner wall of sliding groove, and clamping bottom plate drive clamping block and clamp fixedly the guide rail sliding block to the inboard simultaneously.

The utility model relates to the technical field of valve sleeve machining and clamping, in particular to a clamping device for valve sleeve machining. According to the technical scheme, the clamping device for valve sleeve machining comprises a connecting assembly and further comprises a clamping assembly and a pipe diameter adjusting assembly; clamping assemblies are arranged on the two sides of the connecting assembly; a pipe diameter adjusting assembly is arranged between the two clamping assemblies, and the pipe diameter adjusting assembly is arranged below the connecting assembly. The height of the sliding rod is adjusted by rotating the adjusting threaded rod, so that the clamping piece is driven to rotate around the connecting position of the connecting block to adjust the pipe diameter, finally the valve sleeve is clamped through the first bolt sleeve and the second bolt sleeve, the clamping adjusting function of the valve sleeve is achieved, and the problems that an existing clamping device for valve sleeve machining is inconvenient to use and the like are solved. And when the pipe diameter of the valve sleeve is changed during clamping, clamping adjustment is not flexible, and clamping is difficult.
