Detailed ways

Please refer to Figures 1 to 3. In the embodiment of the present invention, an adjustable turbine box processing jig includes a base 1. A backing plate 2 is fixed at the middle position of the upper surface of the base 1. The backing plate 2 realizes The turbine box is raised when it is fixed, thereby preventing the lower surface of the turbine box from directly contacting the base 1 and preventing the base 1 from being damaged when drilling, and the upper surface of the base 1 is located in the middle of the side of the backing plate 2. Through slots 3, one set of two opposite through slots 3 has a second two-way screw rod 9 rotatably installed inside, and another set of two opposite through slots 3 has a second two-way screw rod 9 installed below the second two-way screw rod 9. The first two-way screw rod 8, the first two-way screw rod 8, and the second two-way screw rod 9 are symmetrically installed with threaded connections and are symmetrically installed with a travel nut 5, and a clamping member 7 is installed on the two opposite travel nuts 5. , through the threaded connection between the first two-way screw rod 8 and the stroke nut 5, and the second two-way screw rod 9 and the stroke nut 5, the distance between the two opposite clamping plates 71 in the two clamping parts 7 can be adjusted respectively, and then the distance between the two opposite clamping plates 71 can be adjusted. Achieving the fixation of turbine boxes of different specifications, the transmission method is simple, which is conducive to later mass production by manufacturers; one end of the first two-way screw rod 8 penetrates the base 1 and is installed with the first knob, and one end of the second two-way screw rod 9 penetrates the base 1 and is equipped with a second knob, which is beneficial to driving the first two-way screw mandrel 8 and the second two-way screw mandrel 9 to rotate respectively.
