Description
Technical field
The present invention relates to a kind of pad processing method, especially relate to a kind of Electric Motor Wheel mine car high accuracy used adjusting pad slice processing method.
Background technology
Existing high accuracy adjusts spacer thickness and diameter ratio 1/54, is relatively large in diameter as 305mm, therefore high accuracy adjusts pad and carries out plane deformation when turning and grinding very greatly, generally machining deformation 0.30-0.55mm is normal.It is used in certain key position of Electric Motor Wheel mine car in view of this part, rises and adjust precision gap and bearing load dual function, not only higher to mechanical property requirements, the highest to flat shape tolerance.If flat shape tolerance is overproof, adjustment precision gap and bearing load will be produced and have a strong impact on, and cause using this part Electric Motor Wheel mine car position overall performance index to decline, and then affect the service life at this position.Thering is provided positioning reference plane for grinding machine in tradition turnery processing, be a leveling face, uncompensated anti-deformation boss plane, when so causing grinding, flat shape tolerance is overproof seriously.
Summary of the invention
The technical problem to be solved is that providing a kind of adds a kind of Electric Motor Wheel mine car high accuracy used adjusting pad slice processing method that post-construction deformation is little, precision is high.
Technical scheme is as follows:
Electric Motor Wheel mine car high accuracy used adjusting pad slice processing method, comprises the following steps:
(1) materials in the tube blanking；
(2) turning；
(3) heat treatment: quenching+tempering；
(4) half finish turnings；
(5) finish turning: before finish turning, materials in the tube either end facet after step (4) half finish turning is got on the bus and cut out an anti-deformation concentric with materials in the tube periphery and compensate boss plane a, its radius is the 1/2 of finished product pad radius, it is highly 0.10mm, then materials in the tube band anti-deformation is compensated boss plane a and carry out finish turning；
(6) half fine grinding: first compensate boss plane a as positioning reference plane with anti-deformation, the opposite side plane that without anti-deformation, materials in the tube are compensated boss plane a carries out half fine grinding, roughness is 0.8 um-1.6um, within flatness is 0.10mm, then materials in the tube boss plane a being carried out half fine grinding, anti-deformation compensates boss plane a and grinds off, making boss plane a roughness is 0.8um-1.6um, within flatness is 0.05mm, make pad；
(7) two planes of pad after step (6) half fine grinding are refined by fine grinding again, and roughness is 0.4um-0.6um, within flatness is 0.05mm, makes satisfactory pad.
Further: the materials in the tube either end facet turning after step (4) half finish turning goes out the boss plane a grinding machine positioning reference plane as first grinding plane of a band anti-deformation compensation.
Further: step (6) to be first energized with anti-deformation compensation boss plane a for positioning reference plane on surface grinding machine workbench and adsorbs retaining element, carry out grinding.
Beneficial effects of the present invention: the high accuracy used adjustment pad deformation of the Electric Motor Wheel mine car after processing is little, precision is high.

Detailed description of the invention:
The present invention is further illustrated below in conjunction with the accompanying drawings.
See the high accuracy used adjusting pad slice processing method of Electric Motor Wheel mine car shown in Fig. 1～Fig. 3, comprise the following steps:
Electric Motor Wheel mine car high accuracy used adjusting pad slice processing method, comprises the following steps:
(1) materials in the tube blanking:
(2) turning:
(3) heat treatment: quenching+tempering；
(4) half finish turnings
(5) finish turning: before finish turning, materials in the tube either end facet after step (4) half finish turning is got on the bus and cut out an anti-deformation concentric with materials in the tube periphery and compensate boss plane, its radius is finished product pad radius 1/2, then materials in the tube band anti-deformation is compensated boss plane and carries out finish turning；This kind of processing method changes and compensates plane without anti-deformation boss when providing positioning reference plane for grinding in tradition turnery processing, changes to leave anti-deformation and compensates boss plane so that forms an annular room between its periphery and materials in the tube periphery.
(6) half fine grinding: first compensate boss plane as positioning reference plane with anti-deformation, the opposite side plane that without anti-deformation, materials in the tube are compensated boss plane carries out half fine grinding, roughness is 0.8 um-1.6um, within flatness is 0.10mm, then materials in the tube anti-deformation being compensated boss plane and carry out half fine grinding, anti-deformation compensates boss plane and grinds off, making this plane roughness is 0.8um-1.6um, within flatness 0.10mm, make pad；nullThe existence in the annular room that boss plane is formed is compensated by step (5) anti-deformation，When being energized absorption retaining element with anti-deformation compensation boss plane on surface grinding machine workbench for positioning reference plane，It is in the shim portions above annular null position and produces downwards micro-strain，When so upset pad grinding anti-deformation compensates boss plane，The buckling deformation of boss plane is compensated owing to grinding heat stress effect makes the plane of first institute's grinding produce anti-deformation dorsad，This kind of buckling deformation is outwards incrementally increased centrally along radius by pad，At this moment pad is because of buckling deformation produced by the micro-strain lucky effective compensation part that produces during above-mentioned retaining element，Within so during grinding, the flatness of first grinding plane is kept to 0.10mm by 0.35mm，It is grinding anti-deformation compensation boss plane and provides hi-Fix datum level.Meanwhile only has the 1/2 of pad radius because anti-deformation compensates boss plan radius, when grinding anti-deformation compensates boss plane, it only has the 1/4 of whole pad area with the contact area of plane mill, grinding heat stress is significantly reduced, the buckling deformation that this plane is produced because of it is the most small, within admissible flatness tolerance 0.05mm, the grinding of such institute goes out within the flatness of plane can reach 0.05mm, substantially increases Product Precision.
(7) fine grinding: being refined in two faces of pad after step (6) half fine grinding, roughness is 0.4um-0.6um, within flatness is 0.05mm, makes satisfactory pad again.When grinding away anti-deformation compensation boss plane because of step (6) half, within the flatness of this plane having been brought up to 0.05mm, using this plane as grinding machine locating and machining datum level, the plane of the first grinding described in grinding step again (6), within the flatness of this plane just can be made to bring up to 0.05mm, take into account-0.6um the requirement of roughness 0.4um simultaneously.Upset pad carries out last finishing grinding to original that one side with anti-deformation compensation boss plane the most again so that it is roughness reaches 0.4um-0.6um.In above-mentioned grinding process, because the flatness of positioning reference plane is largely increased, stock removal is the least simultaneously thus thermal stress that grinding produces is the least, and then the plane warping that pad produces because of grinding heat stress deforms the least, within admissible flatness tolerance 0.05mm.So far the pad roughness, the flatness that are processed all meet drawing requirement.
Wherein the materials in the tube either end facet turning after step (4) half finish turning goes out the boss plane grinding machine positioning reference plane as first grinding plane of an anti-deformation compensation.
Wherein step (6) is first energized with anti-deformation compensation boss plane for positioning reference plane on surface grinding machine workbench and adsorbs retaining element, carry out grinding.
The above embodiment of the present invention scholar's description of the invention and cannot be used for limit the present invention, any change in the implication suitable with claims of the present invention and scope, be all considered as being included within the scope of the claims.
