Aluminum alloy hub lathe fixture

An aluminum alloy hub lathe fixture, comprising:

• a main plate, a mounting seat, a hydraulic power clamping head, a pull rod, a sliding seat, a connecting pin, a fan-shaped clamping jaw, a sealing cover, a deflection block, a deflection shaft, a centrifugal force balance block, a centrifugal mechanism base and a spring, wherein the main plate and the mounting seat are connected together through a first screws, so that a housing of the entire fixture is formed;
• all parts and components are mounted in the fixture, the hydraulic power clamping head is fixed on the mounting seat through second screws, one end of the pull rod is mounted on the hydraulic power clamping head through third screws, and the other end of the pull rod is connected with the sliding seat through the connecting pin;
• the fan-shaped clamping jaw is fixed on the sliding seat through fourth screws, the hydraulic power clamping head drives the sliding seat and the fan-shaped clamping jaw to move forwards and backwards through the pull rod, and the deflection block, the deflection shaft, the centrifugal force balance block and the spring are all mounted on the centrifugal mechanism base, so that a centrifugal force balance system is formed;
• the sealing cover is mounted above the main plate through fifth screws, and the entire fixture is connected with a machine tool through sixth screws;
• and
• wherein the centrifugal force balance system is designed in such a way that under the action of centrifugal force, the centrifugal force balance block can slip towards the outer side and abut against a lower part of the deflection block, so that the deflection block deflects around the deflection shaft, and an upper part of the deflection block abuts against the sliding seat to have the effect of offsetting the centrifugal force of the sliding seat and the fan-shaped clamping jaw.
