Cycloid pin type non-equidistant polar coordinate irregular workpiece water jet cutting device

Abstract

The invention discloses a cycloid pin type non-equidistant polar coordinate irregular workpiece water jet cutting device. The cutting device comprises a two-dimensional numerical control table and anabrasive material jet flow generation device, and further comprises a cycloid pin type adjusting device and an axial adjusting device. The cycloid pin type adjusting device is provided with a verticalmoving table. The upper end of the vertical moving table is provided with a cross beam and a stepping motor I. The lower end of the cross beam is provided with an arc-shaped rack. A swing arm is mounted on an output shaft of the stepping motor I though a flat key. The upper end of the swing arm is provided with a synchronous big gear. The axial adjusting device comprises a circumferential rotaryarm. The right end of the circumferential rotary arm is provided with a synchronous arm. The left end of the synchronous arm is provided with a synchronous small gear. The cycloid pin type non-equidistant polar coordinate irregular workpiece water jet cutting device can achieve the cutting function on irregular workpieces, can conduct cutting on different cutting positions of the irregular workpieces through a local angle and whole-circle angle combined two-stage polar coordinate method and enlarges the space form workpiece cutting and application range.

Description

technical field [0001] The invention relates to the technical field of abrasive water jet mechanical equipment design, in particular to a pendulum type non-equidistant polar coordinate water jet cutting device for special-shaped workpieces. Background technique [0002] The water jet is a high-speed water stream of different shapes formed by the nozzle, and the flow rate of the jet depends on the pressure drop before and after the nozzle outlet section. Water jetting is the simplest form of energy transformation and application. Usually, the power-driven pump completes a suction and discharge process of water, pumps a certain amount of water to the high-pressure pipeline, and makes it reach the nozzle with a certain amount of energy. The hole diameter of the nozzle is required to be much smaller than that of the high-pressure pipeline, so this certain amount of water reaching the nozzle must be accelerated if it wants to flow out of the nozzle hole. In this way, the water ...

Problems solved by technology

[0003] However, the existing water jet cutting devices for special-shaped workpieces cannot realize the function of cutting and processing irregular-shaped workpieces, and some water-jet cutting devices for special-shaped workpieces cannot process The cutting process at different cutting positions on heterogeneous workpieces cannot expand the application range of space-shaped workpiece cutting. Some water jet cutting devices for special-shaped workpieces can neither guarantee the angular displacement of the swing arm around the output shaft of the stepping motor armor at a certain angle. It is impossible to accurately control the moving angle position and increase the stability of the swing arm position locking through the meshing method of the synchronous large gear and the arc-shaped rack. The synchronous pinion meshes with the ring-shaped inner rack to precisely control the position of the full-circle rotation angle and increase the stability of the position locking of the circumferential rotation arm, and the water jet cutting device for special-shaped workpieces cannot drive the circumferential rotation arm to swing around The end of the arm makes a full turn and the position of the nozzle chuck on the turn arm cannot be adjusted
