Special tension clamp for milling of blade type parts

Abstract

The invention discloses a special tension clamp for milling of blade type parts. A tension sensor is arranged in a blade clamp and is used for accurately measuring the prestress on a blade, and the prestress on the blade is adjusted by a screw rod transmission mechanism, so the prestress can be accurately controlled during blade processing, the cutting stability is effectively improved, and the mechanical vibration of the cutting processing is reduced. A fixing clamp is arranged on a base, a movable measuring adjusting device is fixedly arranged on the fixing clamp, a clamping mechanism is arranged at the side surface of the movable measuring adjusting device, and a base is fixedly arranged on a worktable. A clamp head rotates around the center of a rotary indexing table of a machine tool, the tension sensor is connected with the clamp head through a connecting sleeve tube, and when a workpiece is clamped, the influence on the tension sensor by the rotation of the clamp head is avoided, and the measuring is convenient. The clamp has the advantages that the clamp is suitable for clamping and processing the blade type parts on a four-axis milling machine, the processing quality of the part surface is obviously improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a special fixture for milling machines, in particular to a special tensioning fixture for milling blade parts. Background technique [0002] Titanium alloys and high-temperature alloys have good corrosion resistance and high thermal strength, and have been widely used in the aerospace field. However, due to its excellent performance, the cutting performance is also poor. In actual production and processing, a small cutting speed and tangential depth are usually used, and finally surface treatment is performed to improve the fatigue performance of the part material. Research practice has proved that high-speed milling can greatly improve machining efficiency, but the resulting cutting vibration will seriously affect the quality of the machined surface. Especially in the milling process of blades, due to thin blades and poor machining rigidity, the vibration during milling will cause problems of large machining deformation and p...
