Description

TECHNICAL FIELD

[0001] The application relates to the alloy cutting technology field, in particular to a self-adaptive cutting device for alloy special-shaped part machining. BACKGROUND

[0002] The laser cutting utilizes a high-energy laser beam to accurately cut alloy materials, focuses the laser beam on the surface of the alloy material, rapidly heats the alloy material to the melting point or boiling point, and then realizes the melting, vaporization or combustion of the material, so that the cutting process is completed. Laser cutting can meet the processing requirements of complex shapes and high quality. Before some special-shaped workpieces are cut and machined, the workpieces to be machined are also relatively irregular in shape. The special-shaped workpieces to be machined are not easy to be positioned and cut and machined.

[0003] A laser cutting alloy device is disclosed in a patent with the publication number CN220943716U. The laser cutting alloy device includes a bearing assembly, a sliding assembly, a laser assembly, and a preheating assembly. The bearing assembly includes a bearing table and multiple support columns. The small and equal-height support columns are arranged in an array on the top of the bearing table, so that the laser cutting alloy device will not damage the bearing table during cutting. The bearing assembly can bear the sliding assembly, the laser assembly, and the preheating assembly, and enable the laser assembly and the preheating assembly to move in space under the action of the sliding assembly. As a result, the alloy can be cut and preheated by the laser assembly and the preheating assembly. Meanwhile, the laser assembly has a wind cooling member that can blow inert gas after cutting to accelerate the cooling of the alloy.

[0004] A titanium alloy plate laser cutting device for aerospace is disclosed in a patent with the publication number CN114406503B. The device includes a laser cutter, which is fixedly connected with a support frame. Two feeding platforms are symmetrically arranged on the two sides of the laser cutter, and a cutting channel is formed between the two feeding platforms. The laser cutter is arranged above the cutting channel. The pressing mechanism includes an elevator, which is fixedly connected with the feeding platform. The elevator has a sliding block. A connecting frame is connected with the sliding block and an upper pressing plate. Side plates are fixedly arranged on the two sides of the upper pressing plate. An upper pressing seat is fixedly arranged between the two side plates. The first conveying motor is connected with the rotating shaft of the first transmission belt through a chain wheel set. The feeding platform and the pressing mechanism cooperate to continuously clamp the titanium alloy plate during the conveying process. The titanium alloy plate is cut when it moves below the laser cutting head. After cutting, the titanium alloy plate is continuously clamped and conveyed by the feeding platform and the pressing mechanism. Due to the complex shape of the special-shaped workpiece, the clamping stability is poor, and the special-shaped workpiece is easy to shift or vibrate during the machining process. During laser cutting, problems such as cutting burrs and size deviation may occur, which reduces the machining precision and surface quality. Moreover, the poor clamping stability of the special-shaped workpiece leads to frequent adjustment of the clamp or repositioning of the workpiece during the machining process, which increases the machining time and the difficulty of cutting operation.
