Abstract

The invention relates to the field of machining, in particular to a machining method of thin-wall bearing sleeve parts. The method includes the steps of blanking and work-piece blank forging; rough turning, stabilizing and finish turning; and rough grinding of two times. In the rough turning process, technology construction chucks are reserved in forging blanks, rough turning is carried out on work-pieces, and a step circle is added for axially clamping a construction table; the stabilization treatment is added to remove internal stress of the work-pieces further, and sizes of the work-pieces keep stable; and in the finish turning process, 0.9 mm allowance is reserved for diameters of outer circles and holes, and the allowance keeps stable after finish turning. A surface grinding machine is adopted during rough grinding of the first time, two end faces are ground to keep the parallelism degree of 0.05, a center is aligned according to the outer circles, rough grinding is carried out on the outer circles, the holes and the end faces, and the finish grinding diameter allowance is 0.4 mm. The method has the advantages that operation is simple, the accuracy of the work-pieces can be guaranteed, the manufacturing cost is low, parts are easy to disassemble, the use effect is good, the machining quality of the work-pieces can be effectively guaranteed and the efficiency of the work-pieces can be improved, thereby being suitable for volume production of large-diameter thin-wall parts.

Description

The processing method of thin wall shaft bearing sleeve part
Technical field
The present invention relates to field of machining is and in particular to the processing method of thin wall shaft bearing sleeve part.
Background technology
In certain gantry product, there is a kind of typical thin-walled parts thin wall shaft bearing sleeve, its diameter of bore is 165mm, External diameter is 170mm, and the accuracy of form and position that wall thickness is only between 2.5mm, and each size of this part requires higher, outer round surface, hole table Surface roughness is ra0.8um, and cylindrical, hole coaxiality error requires to be less than 0.2mm.Because part wall is thin, poor rigidity, intensity are weak, Work in-process easily deforms, and so that the Form and position error of part is increased, and is difficult to ensure the crudy of part.Thin-wall bearing is enclosed within processing During usually because the reason such as radial force, grinding force, internal stress, make workpiece produce moderate finite deformation it is impossible to ensure part processing Quality, affects assembly period.
Content of the invention
In order to solve the above problems, the present invention provide a kind of simple to operate it is ensured that workpiece accuracy, low cost of manufacture, zero Easily, using effect is good, both can effectively guarantee workpiece processing quality, and can improve workpiece efficiency again, is suitable to straight greatly for part dismounting The processing method of the thin wall shaft bearing sleeve part of footpath thin wall component batch production.
The processing method of thin wall shaft bearing sleeve part of the present invention, comprises the following steps:
The first step, blanking, forge workpiece blank;
Second step, rough turn, stable, smart car, when rough turn, forging blank reserves construction technology chuck, rough turned piece first, increases rank Ladder circle is used for axial grip construction platform;Increase stabilized treatment, eliminate inner stress of work further, make workpiece size keep steady Fixed;During smart car, equal allowance 0.9mm of cylindrical and bore dia, after smart car, allowance keeps steady statue;
3rd step, roughly grinds twice, and corase grind adopts surface grinding machine for the first time, grinds both ends of the surface keeping parallelism degree 0.05, is that lower sequence is omnipotent Mill is layed foundation;Second corase grind adopts grinding machine of universal, inhales inhaled clip construction end surface with sucker, by cylindrical centering center, roughly grind cylindrical, Hole and end face, stay fine grinding amount diameter 0.4mm;
4th step, milling, car, milling adopts vertical machining centre, and with inhaled clip construction end surface as device surface, construction stage is axially pressed from both sides Tightly, by hole centering, interpolation hole milling and cylindrical radial direction six decile concave arc;Cutting data: rotating speed s=240 rad/min, feed f=80 Mm/mim, cutting-in ap=0.05mm;Turning cuts away construction chuck using numerically controlled lathe, lathe cutting parameter during cutting: rotating speed s=80 Rad/min, feeds f=0.06 rnm/min, cuts away construction dop with 2mm width grooving cutter, reduces the deformation of part radial cutting;
5th step, three fine grindings, plain grinding, after construction chuck cut-out, inhale corase grind end face, mill section is it is ensured that the both ends of the surface depth of parallelism 0.01, it is that peripheral milling apparatus lays the first stone;Peripheral milling: with hole positioning, both ends of the surface clamp, and grinding is cylindrical;Omnipotent mill, with grinding outside Circle positioning clamping, with being screwed, inner hole grinding.
The present invention simple to operate it is ensured that workpiece accuracy, low cost of manufacture, easily, using effect is good, both may be used for part dismounting Effectively to guarantee workpiece processing quality, workpiece efficiency can be improved again, be suitable to the batch production of large diameter thin wall class part.
Specific embodiment
The processing method of thin wall shaft bearing sleeve part of the present invention, comprises the following steps:
The first step, blanking, forge workpiece blank;
Second step, rough turn, stable, smart car, when rough turn, forging blank reserves construction technology chuck, rough turned piece first, increases rank Ladder circle is used for axial grip construction platform;Increase stabilized treatment, eliminate inner stress of work further, make workpiece size keep steady Fixed;During smart car, equal allowance 0.9mm of cylindrical and bore dia, after smart car, allowance keeps steady statue;
3rd step, roughly grinds twice, and corase grind adopts surface grinding machine for the first time, grinds both ends of the surface keeping parallelism degree 0.05, is that lower sequence is omnipotent Mill is layed foundation;Second corase grind adopts grinding machine of universal, inhales inhaled clip construction end surface with sucker, by cylindrical centering center, roughly grind cylindrical, Hole and end face, stay fine grinding amount diameter 0.4mm;
4th step, milling, car, milling adopts vertical machining centre, and with inhaled clip construction end surface as device surface, construction stage is axially pressed from both sides Tightly, by hole centering, interpolation hole milling and cylindrical radial direction six decile concave arc;Cutting data: rotating speed s=240 rad/min, feed f=80 Mm/mim, cutting-in ap=0.05mm;Turning cuts away construction chuck using numerically controlled lathe, lathe cutting parameter during cutting: rotating speed s=80 Rad/min, feeds f=0.06 rnm/min, cuts away construction dop with 2mm width grooving cutter, reduces the deformation of part radial cutting;
5th step, three fine grindings, plain grinding, after construction chuck cut-out, inhale corase grind end face, mill section is it is ensured that the both ends of the surface depth of parallelism 0.01, it is that peripheral milling apparatus lays the first stone;Peripheral milling: with hole positioning, both ends of the surface clamp, and grinding is cylindrical;Omnipotent mill, with grinding outside Circle positioning clamping, with being screwed, inner hole grinding.
