Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-5, an inverted T-shaped main clamping base 2 is fixed on a rectangular clamp bottom plate 1, a main clamping oil cylinder 3 and a rectangular positioning seat 4 are arranged on one side of the inverted T-shaped main clamping base, and support legs of an arched connecting seat 13 of the main clamping oil cylinder are fixed with the rectangular positioning seat; an auxiliary clamping and shape changing cushion block 5 is fixed on a clamp bottom plate 1, the auxiliary clamping and shape changing cushion block 5 is arranged at one end of an inverted T-shaped main clamping base 2, an L-shaped auxiliary clamping support 6 is fixed on the upper end face of the auxiliary clamping and shape changing cushion block, an auxiliary clamping oil cylinder 7 and a cylindrical transverse auxiliary supporting oil cylinder 12 are fixed on the side wall of a supporting leg of the L-shaped auxiliary clamping support 6, and the oil cylinder end face of the cylindrical transverse auxiliary supporting oil cylinder corresponds to the end face of an arched shape-setting supporting leg 14 of the auxiliary clamping oil cylinder; a cylindrical longitudinal auxiliary supporting oil cylinder 11 is arranged on the upper end surface of the other supporting leg of the L-shaped auxiliary clamping support; the upper end surfaces of the clamp bottom plates on the two sides of the inverted T-shaped main clamping base are fixedly provided with angular positioning pins 8, the upper end surfaces of the clamp bottom plates on the two sides of the auxiliary clamping and remodeling cushion block are fixedly provided with angular clamping and remodeling cushion blocks 10, and angular clamping oil cylinders 9 are fixed on the angular clamping and remodeling cushion blocks; the angular positioning pin corresponds to the end face of the angular clamping oil cylinder.
The rectangular positioning seat is provided with a shaft positioning hole.
The clamp bottom plate is a whole set of clamp connecting plate, the right side of the clamp bottom plate is provided with an oil pipe joint which is connected with a hydraulic station through a hydraulic hose, and each oil cylinder supplies oil through an oil circuit inside the clamp bottom plate. And fixing the main clamping oil cylinder and the positioning seat by using an inner hexagonal socket head cap screw and then fixing the main clamping oil cylinder and the positioning seat on the main clamping base. The auxiliary clamping oil cylinder, the transverse auxiliary supporting oil cylinder and the longitudinal auxiliary supporting oil cylinder are fixed with the auxiliary clamping support through hexagon socket head cap screws. The angular positioning and clamping oil cylinders are independently arranged on the clamp bottom plate and are fixed by using hexagon socket head cap screws.
