Embodiment Construction

[0035] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below.

[0036] A method for grinding the inner and outer diameters of thin-walled steel parts with stepped holes proposed by the present invention specifically includes the following processing steps:

[0037] S1. The inner and outer diameters and the length of the end face of the thin-walled steel part 1 of the fine-turned step hole. The bottom surface is turned in one clamping to ensure the perpendicularity between the outer circle of the workpiece and the bottom surface of the workpiece, such as figure 1 shown;

[0038] This part is processed by pipe material. If the part structure is not suitable for pipe material processing, in order to avoid material waste, for parts that do not need to withstand high overload and have no special requirements for comprehensive mechanical properties...

Abstract

The invention relates to a method for grinding the inner diameter and the outer diameter of a thin-wall steel part with a step hole. The center alignment adjustment and positioning clamping of the precise thin-wall steel part with the step hole are realized by adopting an innovatively designed clamp, and the problem that in a product production process, when the precise thin-wall steel part with the step hole is subjected to grinding machining, deformation is caused when a clamp clamps, and consequently the part is scrapped is solved. The precise thin-wall steel part with the step hole and the wall thickness larger than or equal to 1 mm can be ground, the dimensional tolerance is within 0.05 mm, and the shape and position tolerance can be guaranteed to be within 0.05 mm. The method is suitable for machining of various precise thin-wall steel parts with the step hole, high in positioning precision, easy to operate, and convenient to assemble and disassemble workpieces, axial clamping force is firmly attracted to a working face through permanent magnets, and radial clamping force can evenly act on a clamped workpiece and can be adjusted within a certain range according to different conditions. The machining range is wide, and the applicability is high.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a method for grinding inner and outer diameters of thin-walled steel parts with stepped holes. Background technique [0002] At present, for the grinding process of the inner and outer diameters of thin-walled steel parts with stepped holes, it is generally first machined to the inner and outer diameters to the reserved grinding size, and then propped up by the three-jaw self-centering chuck to be ground. Grinding the parts, after grinding the outer diameter to the finished product size, then use the special die set to clamp the thin-walled steel parts with the ground outer diameter, and then grind the inner diameter to the finished product size. Under the clamping force of the jaws, the thin-walled parts will be deformed, and eventually the workpiece will be out of tolerance and scrapped, making it unusable. Contents of the invention [0003] The invention pro...
