Abstract
The invention discloses a section processing method for a rollaway nest of a ball screw, which comprises the following steps of: preparing a grinding wheel, wherein the shape of the grinding surface of the grinding wheel is the same as that of the surface radian of the rollaway nest to be processed but the whole size of the grinding wheel is 1-5mm smaller than that of the surface of the rollaway nest to be processed; grinding a single edge at one side of the surface of the rollaway nest to be processed by using the grinding surface at one side of the grinding wheel on request, wherein the grinding surface at the other side of the grinding wheel is not in contact with the surface of the rollaway nest to be processed; moving the grinding wheel in parallel after finishing grinding the single edge and grinding a single edge at the other side of the surface of the rollaway nest to be processed by using the grinding surface at the other side of the grinding wheel, wherein at the grinded side, the grinding surface of the grinding wheel is not in contact with the surface of the rollaway nest to be processed; and obtaining the rollaway nest of a ball screw after finishing grinding the two sides. The invention adopts single edge grinding to reduce tempering layers generated in grinding, thereby enhancing the precision and prolonging the service life of products.
Description
Technical field
The present invention relates to a kind of raceway and cut the shape processing method, specifically a kind of raceway of ball-screw cuts the shape processing method.
Background technology
It all is to adopt the abrasive wheel forming grinding that the raceway that grinds ball-screw now cuts shape, sees Fig. 1, among the figure, and emery wheel 1, raceway 2.Used emery wheel 1 grinding face is identical with the shape on raceway 2 surfaces, one-shot forming during grinding.The shortcoming that this raceway cuts the shape processing method is: contact area is big during owing to the wheel grinding moulding, thereby the grinding tempering layer that raceway face produces during grinding is just very dark, emery wheel surface abrasion when normal the use is very fast, causes the precision of product to descend rapidly, and the life-span also descends thereupon; And owing to be contact completely, higher to the rigidity and the requirement of strength of lathe, be easy to generate the relatively poor phenomenon of surface smoothness.
Summary of the invention
The big problem of contact area when having wheel grinding now in order to overcome, the raceway that the purpose of this invention is to provide a kind of ball-screw cuts the shape processing method, this processing method adopts monolateral grinding to reduce the tempering layer that grinding produces, and has improved the precision and the service life of product.
The objective of the invention is to be achieved through the following technical solutions:
A kind of raceway of ball-screw cuts the shape processing method, it is characterized in that this processing method adopts monolateral grinding to reduce the tempering layer that grinding produces, and improves the precision and the life-span of product, and concrete steps are as follows:
1) prepare emery wheel, the grinding face of emery wheel is identical with raceway face radian shape to be processed, but the grinding face overall dimensions is less than raceway face 1-5mm to be processed;
2) carry out grinding, at first carry out grinding with a side grinding bevel of emery wheel on request to a side of raceway face to be processed is monolateral, at this moment, the opposite side grinding face of emery wheel does not contact with raceway face to be processed; After monolateral grinding was finished, the translation emery wheel carried out grinding with the opposite side grinding face of emery wheel on request to the opposite side of raceway face to be processed is monolateral, and finished a side of grinding this moment, and the grinding face of emery wheel does not contact with raceway face to be processed;
3) after the equal grinding in both sides is finished, obtain the raceway of ball-screw.
Among the present invention, the grinding face overall dimensions is less than raceway face 3mm to be processed.Step 2) in, is the line of demarcation, at first one side of something of raceway face to be processed carried out grinding on request with the half of grinding face of emery wheel with the center line of wheel grinding face and the center line of raceway face to be processed; After half of grinding was finished, the translation emery wheel carried out grinding with the half of grinding face in addition of emery wheel on request to other one side of something of raceway face to be processed.
Compared with prior art, the present invention adopts the method for monolateral grinding, has reduced the tempering layer that grinding produced, and has improved the grinding accuracy of ball-screw raceway, has prolonged the service life of emery wheel; And owing to be monolateral contact, lower to the rigidity and the requirement of strength of lathe, the surface smoothness height.
The present invention not only can be used for the raceway of grinding ball-screw, also can be used for other similar raceway of grinding, and original one-shot forming is changed into twice or repeatedly moulding, has avoided because the problem of the too big existence of Grinding Contact face.
Description of drawings
Fig. 1 is the schematic diagram that adopts emery wheel one-shot forming grinding ball-screw raceway at present;
Fig. 2 is the schematic diagram that the present invention adopts monolateral method for grinding grinding ball-screw raceway.
The specific embodiment
A kind of raceway of ball-screw of the present invention cuts the shape processing method, see Fig. 2, this processing method adopts monolateral grinding to reduce the tempering layer that grinding produces, and has improved the grinding accuracy of ball-screw raceway, prolonged the service life of emery wheel, concrete steps are as follows:
Prepare emery wheel, the grinding face of emery wheel 11 is identical with raceway 12 surperficial radian shapes to be processed, but the grinding face overall dimensions is less than raceway face 1-5mm to be processed; Can select 3mm.
Carry out grinding, at first carry out grinding on request to a side on raceway to be processed 12 surfaces is monolateral with a side grinding bevel of emery wheel 11, can be the line of demarcation with the center line of wheel grinding face and the center line of raceway face to be processed, at first one side of something of raceway face to be processed be carried out grinding on request with the half of grinding face of emery wheel; At this moment, the half of grinding face in addition of emery wheel does not contact with raceway face to be processed; After half of grinding was finished, the translation emery wheel carried out grinding with the half of grinding face in addition of emery wheel on request to one side of something in addition of raceway face to be processed, has finished one side of something of grinding at this moment, and the grinding face of emery wheel does not contact with raceway face to be processed; Smooth transition is answered in the two halves junction, guarantees to meet the demands.
After the equal grinding in both sides is finished, obtain the raceway of ball-screw.
The present invention adopts the method for monolateral grinding, has reduced the tempering layer that grinding produced, and has improved the grinding accuracy of ball-screw raceway, has prolonged the service life of emery wheel; And owing to be monolateral contact, lower to the rigidity and the requirement of strength of lathe, the surface smoothness height.
