Multi-stage cylinder line marking and drilling safety tool, multi-stage cylinder line marking method and multi-stage cylinder drilling machining method

Abstract

The invention belongs to machining devices, and particularly relates to a multi-stage cylinder line marking and drilling safety tool, a multi-stage cylinder line marking method and a multi-stage cylinder drilling machining method. The multi-stage cylinder line marking and drilling safety tool comprises a horizontal base plate. A vertical supporting baffle is fixedly installed on the front portion of the base plate. A clamping mechanism which faces the supporting baffle and can horizontally move forwards and backwards is installed on the rear portion of the base plate. A pair of horizontal rolling shafts which are parallel to each other are installed on the two sides of the base plate, the two ends of each horizontal rolling shaft are installed on supporting bases through bearings, and a rocking handle which can drive the horizontal rolling shafts to rotate is installed at the end of at least one horizontal rolling shaft. The external circumference of a cylindrical workpiece can be installed between the two horizontal rolling shafts and is tangent with the horizontal rolling shafts, and the two axial ends of the cylindrical workpiece can be axially clamped and fixed or released by the clamping mechanism and the supporting baffle facing the clamping mechanism. The multi-stage cylinder line marking and drilling safety tool is simple in structure, high in clamping accuracy, good in stability and high in safety, and convenient to operate and firm to clamp.

Description

technical field [0001] The invention belongs to a mechanical processing device, and in particular relates to a multi-stage cylindrical scribing and drilling safety tooling and a scribing and drilling processing method. Background technique [0002] In the machining of large-scale multi-stage cylindrical workpieces, such as cylindrical workpieces with a diameter of more than 400mm, when marking and drilling on the outer circle, due to the heavy weight of the workpiece, the shift of the center of gravity of the multi-stage cylindrical workpiece, the workpiece cannot be placed stably , Difficult to clamp, inconvenient to move, conventional tooling fixtures have great safety hazards, and safety accidents are prone to occur during the marking process. In the absence of suitable special tooling for scribing and processing, using traditional height gauges and pad irons for operations, it is difficult to guarantee safe production and product processing quality, and the processing ef...

[0002] In the machining of large-scale multi-stage cylindrical workpieces, such as cylindrical workpieces with a diameter of more than 400mm, when marking and drilling on the outer circle, due to the heavy weight of the workpiece, the shift of the center of gravity of the multi-stage cylindrical workpiece, the workpiece cannot be placed stably , Difficult to clamp, inconvenient to move, conventional tooling fixtures have great safety hazards, and safety accidents are prone to occur during the marking process

In the absence of suitable special tooling for scribing and processing, using traditional height gauges and pad irons for operation, it is difficult to guarantee safe production and product processing quality, and the processing efficiency is low, which cannot meet high-quality and efficient processing requirements
