A floating clamping device of a hollow pipe fitting straightening machine

Abstract

The invention discloses a floating clamping device of a hollow pipe fitting straightening machine. The floating clamping device comprises an external protection device, a rotation device, a base fixing plate, a spring, an ejector pin, a swivel nut, an oil cylinder, a nut A, a front end cover, a sliding platform, a rear end cover, a shifting device and a clamp, wherein the rotation device comprises a fixed plate, a hydraulic chuck, a synchronous belt, a belt pulley, a tumbler, a motor flange, a servo motor A, a motor base and a reducer; the oil cylinder comprises a bearing, an oil cylinder piston, a cylinder head, a cylinder body, an oil cylinder fixing plate and a cylinder bottom; the sliding platform is arranged on the oil cylinder; the shifting device comprises a gear, a worm-gear, a flat key, a reduction deice, a servo motor B and a bottom plate; and the clamp is arranged on the shifting device. The floating clamping device can realize the movement of the clamp in the horizontal direction and the vertical direction, can drive the clamp clamping hollow pipe fittings to rotate, is simple in structure and convenient to operate, and has a relatively high adjustment precision.

Description

technical field [0001] The invention relates to the field of floating clamping, in particular to a floating clamping device of a hollow pipe straightening machine. Background technique [0002] At present, many countries have adopted automatic straightening equipment technology to replace manual straightening equipment technology, and the straightening equipment technology for hollow pipe fittings is particularly complicated. In order to realize the clamping work and rotation measurement of hollow pipe fittings before straightening, the clamping device of the straightening machine needs to be able to move in multiple directions, and has certain requirements for the accuracy of the moving displacement. It is difficult for the clamping device of a general straightening machine to completely adjust the position of the fixture in multiple directions, or the displacement accuracy of the adjustment cannot be guaranteed, and the floating adjustment of the hollow pipe in the vertica...

Problems solved by technology

It is difficult for the clamping device of a general straightening machine to completely adjust the position of the fixture in multiple directions, or the displacement accuracy of the adjustment cannot be guaranteed, and the floating adjustment of the hollow pipe in the vertical direction cannot be realized to make it close to the horizontal state, resulting in alignment Influenced by the direct process, the error increases
