A damping and anti-vibration supporting device for the turning processing of crane cylindrical parts

Abstract

A damping and anti-vibration supporting device for turning cylindrical parts of a crane, including a base, a slide rail, a sliding seat, a driving mechanism, a support wheel, and a rotation damping mechanism. The bottom surface of the base is in sliding connection with the guide rail of a lathe. There is a slide rail on the surface, the axis of the slide rail is perpendicular to the axis of the lathe guide rail, the slide rail slides with two sliding seats, and the base is equipped with a driving mechanism that can drive the two sliding seats to move toward or away from each other; the top of the two sliding seats A support wheel is provided respectively, and a rotation damping mechanism is respectively provided on the two sliding seats; the rotating damping mechanism includes a housing, a squeeze disc and a gear, and the housing is a box structure with one side open, and the opening surface of the housing is sealed corresponding to the side of the sliding seat. connected, and the side of the open end of the shell is provided with an oil filling port, and the shell is equipped with a squeeze plate, which can seal and slide in the direction of the sliding seat, the gear is located in the shell, and the gear is connected to the axle of the supporting wheel correspondingly, and The device can improve the processing quality of thin-walled cylindrical parts.

Description

technical field [0001] The invention relates to the technical field of processing crane cylindrical parts, in particular to a damping and anti-vibration supporting device for turning processing of crane cylindrical parts. Background technique [0002] As is known, the reels and drums of cranes generally use cylindrical parts with large diameters and long thin walls. However, due to the large amount of surface processing and thin wall thickness of the cylindrical parts, the cylindrical parts are processed by a lathe The end of the three-jaw chuck is clamped, resulting in a lack of support for the cylinder body, so cutting vibrations will occur during the machining process, and then the surface of the cylindrical part will often produce chattering lines after turning, so the cylindrical part In the next step of processing, secondary tool vibration will occur, which will seriously affect the processing quality of the product; [0003] Chinese patent (CN201510594689.X) disclose...

Problems solved by technology

[0002] As is known, the reels and drums of cranes generally use cylindrical parts with large diameters and long thin walls. However, due to the large amount of surface processing and thin wall thickness of the cylindrical parts, the cylindrical parts are processed by a lathe The three-jaw chuck clamps its end, resulting in a lack of support for the cylinder body, so cutting vibrations will occur during the machining process, and then the surface of the cylindrical part will often produce chattering lines after turning, so the cylindrical part In the next step of processing, secondary tool vibration will occur, which will seriously affect the processing quality of the product;

[0003] Chinese patent (CN201510594689.X) discloses a mechanical fixed force clamping self-locking device and method for thin-walled parts. The device uses a spring to provide a fixed pressure to push the compression block to compress the workpiece, and then drives the side through the cylinder push rod The oblique wedge block expands the compression block, and finally the workpiece is clamped by the clamping ring at the bottom of the compression block to achieve the purpose of self-locking; but this device only compresses the workpiece, and cannot solve the cutting vibration during processing , still affects the processing quality of the workpiece; therefore, in summary, there is a need for a device that can improve the processing quality of thin-walled cylindrical parts in the market
