The invention relates to a universal pressing mechanism of a steam turbine blade drilling jig, which includes a frame composed of an upper cover plate, a lower cover plate, a left cushion block and a right cushion block, and the upper cover plate and the lower cover plate are respectively provided with corresponding The corresponding chute is provided with a plurality of notches, and a universal slider is arranged between the upper cover plate and the lower cover plate. The upper and lower sides of the universal slider are respectively provided with support shafts. The support shaft on the upper side is installed in the chute of the upper cover, and the support shaft on the lower side of the universal slider is installed in the chute of the lower cover. The universal slider is movably connected with a pressure rod. The axial crossing of the supporting shaft is arranged, and a pressing head is arranged at one end of the pressing rod. The invention includes a chute, a universal slider, a pressure rod and a pressure head, and has simple structure, strong versatility, and low cost of use. The blade is pressed by the pressure head, which is easy to operate, and the pressure head is connected to the universal slider through the pressure rod. , The universal slider slides in the chute, with flexible adjustment and high efficiency.
Description
(1) Technical field [0001] The invention relates to tooling for mechanical processing, in particular to a universal pressing mechanism of a steam turbine blade drilling fixture. (2) Background technology [0002] The steam turbine blade profile is a twisted profile, and the blade profile processing usually uses three center holes for positioning. The three center holes are the processing positioning reference, so the processing requirements are relatively high, and a special drilling jig is required to ensure it. [0003] Existing drill jig structure such as figure 1 , figure 2 As shown, it consists of two left and right columns 1 and two base plates 8 up and down to form a clamp body; an upper drill plate 2 is fixed below the base plate 8 above the clamp body, and an upper top 4 is fixed on the upper drill plate 2; the base plate below the clamp body 8 is fixed with a lower drill plate 9, and two lower tops 10 are fixed on the lower drill plate 9; two columns 1 inboards...
