Embodiment 1

[0036] In this embodiment, the length of the corrugated cylinder is 1000mm, and the diameter is 650mm; the equipment for removing the burrs from the sieve holes of the corrugated cylinder is composed as follows: the corrugated cylinder rotating motor 1 is fixed on the fixed bracket A2 through bolt connection, the corrugated cylinder rotating motor 1 axis and the corrugated cylinder The clamps 17 are concentric and fixedly connected. When the corrugated tube clamp 17 clamps the corrugated tube 3, the corrugated tube rotating motor 1 is powered on, and the corrugated tube clamp 17 clamps the corrugated tube 3 to rotate positively and negatively, and the direction of rotation is the same as that of the magnetic grinding head. On the contrary, it is beneficial to improve the grinding effect. The grinding head tilt adjustment shaft 5 can adjust the angle between the axis of the magnetic permeable iron ring 15 and the horizontal direction. Adjust the axis of the magnetically permeab...

Embodiment 2

[0040] The corrugated cylinder processed in this embodiment has a length of 1200mm and a diameter of 800mm; The rotational speed of the grinding head drive motor 14 is 600r / min, and the reversing speed of the bellows 3 is 400r / min; the lateral linear movement speed of the grinding head is 6cm / min; the abrasive composition used is Al 2 o 3 and Fe sintered abrasives, adding oily grinding fluid to the abrasives. Grind and change the abrasive material every 20 minutes. The abrasive material diameter is 20 meshes; the grinding time is 45 minutes; the magnetically conductive iron ring 15 has a diameter of 30mm and a length of 130mm; the gap between the trapezoidal magnet 19 and the corrugated cylinder 3 is 4mm.

Embodiment 3

[0042] The corrugated cylinder processed in this embodiment is a conical corrugated cylinder with a length of 800mm and diameters of both ends of the corrugated cylinder of 400mm and 600mm; Adjust the angle between the axis of the magnetically permeable iron ring 15 and the horizontal direction so that the magnetically permeable iron ring 15 is parallel to the wall of the conical corrugated cylinder 3; the grinding head support 16 is fixed and locked by the inclination angle locking screw 4 . The grinding head traverse motor 9 drives the magnetic grinding head to move horizontally in the corrugated cylinder 3; the longitudinal linear module motor 12 drives the magnetic grinding head to move up and down; the distance between the trapezoidal magnet 19 and the cylinder wall is kept constant, making the grinding of the surface of the corrugated cylinder 3 easier Uniform and dense.

[0043] Grinding head driving motor 14 rotating speed is 800r / min, corrugated tube 3 reverse speed i...

Abstract

The equipment and process used to remove the burr from the screen hole of the corrugated cylinder, the equipment includes the positioning component of the corrugated cylinder, the lateral movement component of the grinding device, the longitudinal movement component of the grinding device, the driving device of the grinding head, the tilt adjustment shaft of the grinding head, the locking screw of the tilt angle, the grinding The lead screw of the horizontal moving component of the device extends into the corrugated cylinder and is set eccentrically with the axis of the corrugated cylinder. The longitudinal moving component of the grinding device is arranged at the lower end of the horizontal moving component of the grinding device, which drives the horizontal moving component of the grinding device to move up and down, and the grinding head driving device passes through The grinding head tilt adjustment shaft is installed on the lead screw slider, and the relative angle between the grinding head driving device and the lead screw is determined and then locked and positioned by the tilt angle locking screw. The invention realizes deburring of different types of cylindrical corrugated cylinders and conical corrugated cylinder screen holes through magnetic grinding. The invention has the advantages of simple structure, high grinding precision, good polishing performance, wide versatility, low cost and high reliability.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a device and a process for removing burrs from the screen hole of a corrugated cylinder. Background technique [0002] In the field of aerospace, the aeroengine is a crucial power system, almost its power comes from the energy combustion of the afterburner, so it is bound to cause the temperature of the engine combustion chamber to rise suddenly, and the heat insulation bellows in the combustion chamber can play a very important role. Good heat insulation prevents heat from being transferred to the engine, ensures stable performance of the engine, and improves service life. Therefore, the quality requirements for the heat-insulating corrugated tube are relatively high, and there are many tiny burrs and wrinkles on the surface of the heat-insulating corrugated tube, which affect the heat-insulating effect of the heat-shielding screen. Removing tiny burrs on the surface of cor...
