Abstract
The utility model provides a frock of ultra -thin narrow bearing annex processing, includes work piece, numerical control lathe jack catch, numerical control lathe lathe tool, supplementary mould. Supplementary mould suit on the external diameter of work piece to press from both sides the work piece tightly on the numerical control lathe jack catch through supplementary mould. The numerical control lathe lathe tool is established to two, is internal diameter cut off lathe tool and external diameter cut off lathe tool respectively, and internal diameter cut off lathe tool and external diameter cut off lathe tool set up respectively in the same axial dimensions's of work piece internal diameter and external diameter both sides, and when work piece cut off, internal diameter cut off lathe tool and external diameter cut off lathe tool 12, the cut off of axial turner thickness simultaneously become two. The utility model provides a difficult problem of the unable processing of ultra -thin narrow serial bearing annex, the technology and equipment design of bearing annex processing and auxiliary fixtures's use have improved product machining efficiency greatly, assurance product precision has reduced the processing cost.
Description
Technical field
This utility model is related to bearing accessory processing technique field, more particularly to a kind of ultra-thin narrow bearing accessory processing
Frock.
Background technology
Ultra-thin narrow series bearing accessory is for example：26M107-14 covers adnexa（Technical requirements as shown in Figure 5)：（1）Heat treatment is hard
Degree：58～62HRC；(2) machining accuracy presses the execution of four-row cylindrical roller bearing for rolling mill inner ring technical conditions.Outside this product
Footpath：φ 647.718, internal diameter：φ 630, end face：58, so as to calculate the effective thickness of this product：（647.718-630）÷2=
8.859, it is known that this product is a kind of bearing accessory of ultra-thin narrow series, and required precision is tighter, normal process（1）
Single processing ellipse is unable to reach greatly technical requirements.（2）The processing if two pieces is integrated, when cutting off, due to product it is too thin
Pinching deformation is big, causes fragmentation.（3）If using linear cutter, mill processing additional must be tempered more than secondary, and grinding stress is special
In the case of little could linear cutter, otherwise when will also result in wire cutting, there is fragmentation phenomenon, therefore use wire cutting
High processing costs, efficiency are low.So solving the problems, such as that ultra-thin narrow series bearing accessory machining accuracy and improve production efficiency are one
A tackling key problem difficult problem.
Utility model content
The technical problems to be solved in the utility model is to provide one kind and is greatly improved Product processing efficiency, it is ensured that product
Precision, reduces the frock of the ultra-thin narrow bearing accessory processing of processing cost.
Using technical scheme be：
A kind of frock of ultra-thin narrow bearing accessory processing, including workpiece, numerically controlled lathe claw, CNC lathe tool, auxiliary
Mold.Described auxiliary mold is sleeved on the external diameter of workpiece, and by aiding in mold by Workpiece clamping in numerically controlled lathe claw
On.The CNC lathe tool is set to two, and respectively internal diameter cuts off lathe tool and external diameter cuts off lathe tool, and internal diameter cuts off lathe tool and outer
Footpath cuts off internal diameter and the external diameter both sides that lathe tool is separately positioned on the same axial dimension of workpiece, and when workpiece cuts off, internal diameter cuts off
Lathe tool and external diameter cut off lathe tool and meanwhile axial turner thickness 1/2, cut off into two pieces.
Above-mentioned auxiliary mold, its internal diameter size must with the external diameter actual size match grinding of workpiece, gap be 0.05～
0.08mm；Between both ends of the surface, size is workpiece whole height × 0.5-5～8mm；In addition in the cutting for being axially arranged with 2.0mm at
Gap.
Above-mentioned workpiece integrally closes forging using two pieces, and the process area for reducing tempering deformation of quenching, tempering of quenching are provided with the middle of workpiece
Turning and grinding are adopted afterwards to finished size.
This utility model solves the difficult problem that ultra-thin narrow series bearing accessory cannot be processed, the technique work of bearing accessory processing
The use of installing meter and auxiliary mould, substantially increases Product processing efficiency, it is ensured that Product Precision, reduces processing cost.

Specific embodiment
A kind of frock of ultra-thin narrow bearing accessory processing, including it is workpiece 3, numerically controlled lathe claw 4, CNC lathe tool, auxiliary
Help mold 2.The workpiece 3 integrally closes forging using two pieces, and the process area for reducing tempering deformation of quenching is provided with the middle of workpiece（See Fig. 4）,
Quench after being tempered using turning and grinding to finished size.The auxiliary mold 2, its internal diameter size must be with the external diameter reality of workpiece
Border size match grinding, gap is 0.05mm；Between both ends of the surface, size is workpiece whole height × 0.5-6mm；It is being axially arranged with one in addition
The cutting gap of place 2.0mm（See Fig. 2, Fig. 3）.Described auxiliary mold 2 is sleeved on the external diameter of workpiece 3, and by aiding in tire
Tool 2 by Workpiece clamping on numerically controlled lathe claw 4.The CNC lathe tool is set to two, and respectively internal diameter cuts off 5 He of lathe tool
External diameter cuts off lathe tool 1, and internal diameter cuts off lathe tool 5 and external diameter cuts off the internal diameter that lathe tool 1 is separately positioned on 3 same axial dimension of workpiece
With external diameter both sides（See Fig. 1）, when workpiece cuts off, internal diameter cuts off lathe tool and external diameter cuts off lathe tool while axial turner thickness
1/2, cut off into two pieces, cut off rear reconditioning end face to finished size（As shown in Figure 5）.
