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 invention relates to equipment and a technology for burr removing of corrugated tube sieve pores. The equipment includes a corrugated tube location assembly, a grinding device transverse moving assembly, a grinding device longitudinal moving assembly, a grinding head drive device, a grinding head slant regulating shaft and slant angle locking bolts, and a lead screw of the grinding device transverse moving assembly extends into a corrugated tube and is eccentrically arranged with the axis of the corrugated tube; and the grinding device longitudinal moving assembly is arranged at the lowerend of the grinding device transverse moving assembly to drive the grinding device transverse moving assembly to vertically move, the grinding head drive device is installed on a lead screw sliding block through the grinding head slant regulating shaft, and the slant angle locking bolts are used for locking and positioning when a relative angle of the grinding head drive device and the lead screwis determined. According to the equipment and technology for the burr removing of the corrugated tube sieve pores, burrs of cylindrical corrugated tubes and cone corrugated tube sieve pores with various types can be removed through magnetic grinding; and the structure is simple, the grinding precision is high, the polishing performance is good, the universality is wide, the cost is low, and the reliability is high.

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...
