[0001] The utility model relates to hydraulic fixture technical field, concretely is a kind of hydraulic fixture for flange drilling. BACKGROUND

[0002] Hydraulic fixture is a kind of device using the pressure generated by hydraulic system to realize the fast and accurate clamping of workpiece. It receives high-pressure oil flow from hydraulic pump through hydraulic cylinder, converts fluid energy into mechanical energy, and drives piston rod to move, thereby generating clamping force.

[0003] The existing flange needs to be clamped by hydraulic fixture when drilling to ensure the stability of flange drilling. Generally, a support is used to ensure that the clamp can be stably installed on the surface of the workbench. The pressure mechanism is composed of a hydraulic cylinder, which is used to generate clamping force to firmly fix the flange on the clamp to prevent displacement and vibration during drilling.

[0004] However, due to the huge rotational force generated by the drill bit during drilling, the rotation of the drill bit will generate a cutting force along the axis when it first contacts the surface of the flange. If this force is not effectively transmitted to the fixing device or if the fixing device itself is not stable enough, the flange may rotate with the drill bit. The hydraulic fixture clamps the flange from both sides, which is difficult to resist the cutting force along the axis generated by the drill bit, resulting in the flange being easily offset and unable to accurately drill the flange.
