In this way, the machining deformation of a thin-walled bearing ring can be reduced, and the machining accuracy of a product can be ensured.
Description
Technical field
The present invention relates to machinery manufacturing technology field, particularly relate to a kind of thin-wall bearing ferrule Vehicle Processing technique.
Background technology
Thin-wall bearing is requirement for main machine structure narrow space or property and designs, and when the external diameter of bearing and the ratio of internal diameter are less than or equal to 1.143, is called thin-wall bearing.During thin-wall bearing ferrule Vehicle Processing, under cutting force effect, easily cause thermal deformation and produce vibration deformation, thus affect the dimensional accuracy, the accuracy of form and position etc. of part, make it to deform, this is mainly because two reasons cause: 1) clamp external diameter or internal diameter, can be swollen, now by retaining part because of elastic deformation, the internal diameter of part or the ovality of cylindrical not easily ensure, thus affect the morpheme size of part; 2) impact of cutter, this type of part is easy to distortion under the effect of cutting force, easily causes the phenomenons such as bite inequality and cutter relieving, in length, easily produces tapering during hole machined.Improper due to processing method, in process, distortion this problem large could not solve always well.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, provides a kind of thin-wall bearing ferrule Vehicle Processing technique, can reduce the machining deformation of thin-wall bearing ferrule, ensures the machining accuracy of product.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of thin-wall bearing ferrule Vehicle Processing technique, comprise the following steps:
1) rough turn: the cylindrical of numerical control turning thin-wall bearing ferrule part, endoporus, raceway groove and both ends of the surface, control the surplus that cylindrical stays 0.3-0.5mm, endoporus stays the surplus of 0.6-0.8mm, and raceway groove stays the surplus of 0.2-0.3mm, and both ends of the surface stay the surplus of 0.2-0.5mm;
2) annealing in process: by the thin-wall bearing ferrule part annealing in process 3-4 hour at 650-680 DEG C of temperature after rough turn, then cool to 180-200 DEG C with the furnace, then air cooling of coming out of the stove;
3) finish turning: the cylindrical of the thin-wall bearing ferrule part after numerical control turning annealing in process, endoporus, raceway groove and both ends of the surface, by the size car of cylindrical, endoporus, raceway groove and both ends of the surface to grinding required size.
In a preferred embodiment of the present invention, the material of described thin-wall bearing ferrule part is Gcrl5, through forging molding.
In a preferred embodiment of the present invention, the wall thickness of described thin-wall bearing ferrule part is 12-30mm.
In a preferred embodiment of the present invention, when step 1) is rough turn, select the fillet blade of R0.8-R1.0.
In a preferred embodiment of the present invention, during step 3) finish turning, select the blade of cutter head band 0.2 × 20 ° of negative chamfered edge, the amount of feeding controls at 0.1-0.2mm/rad.
The invention has the beneficial effects as follows: that by increasing annealing process after rough turn technique the cutting stress produced when removing roughing reduces the machining deformation of thin-wall bearing ferrule; Allowance when conservative control is rough turn simultaneously, chooses special lathe processing tool bit, controls the amount of feeding, avoids the phenomenons such as bite inequality and cutter relieving, ensures the machining accuracy of product.
