Embodiment

[0026] The slewing bearings on the machines imported by Yulong Company are ultra-thin ring parts. Since the production of ultra-thin ring parts is not yet mature in China, many units have not produced them. Our company uses the ultra-thin ring parts proposed by this invention to process method, and successfully produced ultra-thin ring parts on slewing bearings made in Germany, wherein: the size of part 1 is φ609 -0.175 0 / φ568 0 +0.175 ×3.5 -0.04 -0.01 mm, the size of piece 2 is φ617 -0.175 0 / φ561 0 +0.175 ×4.5 -0.04 -0.01 mm; and for the two surfaces, there are also geometric tolerance requirements for flatness less than 0.06mm and parallelism less than 0.06mm;

[0027] Process the above two products according to the processing technological process of the present invention:

[0028] 1) Cutting blank:

[0029] Part 1 is to produce four ultra-thin annular parts, and the steel plate is flame-cut and blanked, and the thickness of the blank is calculated according t...

Abstract

The invention relates to a processing method of ultra-thin annular pieces. The method comprises the following process flows of: (1) cutting a blank; (2) roughly turning; (3) drilling; (4) dividing single pieces; (5) manufacturing a tool clamp; (6) combining and fine turning; and (7) turning or grinding planes. 4-10 ultra-thin annular pieces are combined together, and meanwhile, steel plate flames are used for cutting and integrally blanking so as to improve the rigidity and ensure that no deformation occurs in the processing process. Semi-finished ultra-thin annular piece products to be processed, which are cut and blanked into single pieces, need to be combined together with the tool clamp, wherein the tool clamp is an annular piece with inner and outer steps between an upper section and a lower section. The circumference on the upper end surface of the tool clamp is uniformly provided with threaded holes according to the mounting hole sizes of the ultra-thin annular pieces, and then the single semi-finished products of the ultra-thin annular pieces to be processed are combined with the tool clamp into a whole by using bolts so as to enhance the rigidity of the semi-finished ultra-thin annular piece products, guarantee non-deformation during processing in subsequent working procedures, realize the localization of the ultra-thin annular pieces to replace imported pieces, greatly reduce the cost and meet the requirement of users.

Description

technical field [0001] The invention belongs to a machining method of a machine tool, in particular to a machining method of a ring piece. Background technique [0002] Ultra-thin rings refer to rings with a thickness less than 5mm, a diameter greater than 500mm, and size and shape tolerance requirements; due to their poor rigidity, ultra-thin rings are subjected to the clamping force and cutting force of the jaws during processing. Elastic and plastic deformation occurs under the action of feed force. This kind of ultra-thin ring parts often appears in imported equipment accessories. However, there is no mature ultra-thin ring part processing technology in the domestic ring part processing field. The existing process processing Ultra-thin ring parts exist: (1) The ultra-thin ring parts are plastically deformed, and the shape and position tolerance cannot meet the requirements. (2) Ultra-thin ring parts are prone to elastic deformation, and the dimensional tolerance cannot ...
