Abstract
The invention relates to a bearing sleeve ring grinding process floating support device which comprises a floating base and a floating head seat hinged with the floating base. Two ceramic supporting blocks used for supporting a sleeve ring are mounted on the floating head seat, and supporting planes of the ceramic supporting blocks are higher than the plane of the floating head seat. The ceramic supporting blocks are adopted, so that sufficient supporting force can be provided, no trace can be left on the surface of the sleeve ring, repair processing is not needed, processing processes are reduced, workload is reduced, processing time is reduced, and production cost is lowered.
Description
Technical field
The present invention relates to bearing processing apparatus technical field, especially a kind of bearing ring grinding technique floating support device.
Background technology
Bearing is in mechanical transmission course, play parts that are fixing and reduction load coefficient of friction.Alternatively, when other parts produce relative motion each other on axle, be used for reducing the fixing parts of coefficient of friction in power transmission process and retainer shaft center.Bearing mainly comprises lasso and rolling element, and lasso comprises outer ring and inner ring, and lasso in process of production, finally needs grinding lasso surface to carry out fine finishining, to reach size and the form and position tolerance of designing requirement, as surface roughness, percent ripple, axiality etc.When the large style ferrules of grinding, because of heavier mass, need to support at gravity direction and direction of feed, existing supporting mechanism is Hardmetal materials, vestige clearly can be left on lasso surface, need the reparation operation carrying out being correlated with, add workload, increase production cost, extend process time.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the technical problem that in prior art, lasso bracing or strutting arrangement in grinding is left a trace, and provides a kind of bearing ring grinding technique floating support device, supports vestige not obvious, without the need to reprocessing, reduces treatment process.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bearing ring grinding technique floating support device, comprise floating mount and the floating headstock hinged with floating mount, described floating headstock is provided with two for supporting the ceramic support block of lasso, the supporting plane of two ceramic support blocks is higher than the plane of floating headstock.Hinged between floating mount and floating headstock, automatically can adapt to the outer ring of bearing ring, ceramic support block provides radial support power, contacts can not leave a trace on lasso with lasso, also carries out reparation operation with regard to not needing, and reduces treatment process.
Concrete, described ceramic support block is cylindrical, the axis being parallel of two cylindrical ceramic back-up blocks, described floating headstock has the pocket hole that two are installed cylindrical ceramic back-up block.
Further, two described ceramic support blocks are one in front and one in back arranged in vertical axis direction.
Further, the quantity of described floating headstock is two, and two described floating headstocks are one in front and one in back arranged in pivot center direction, the V-shaped setting of supporting plane of the ceramic support block on two floating headstocks.Two floating headstocks can better be fitted lasso surface, provide reliable support force, avoid point cantact.
Further, adjustable for realizing degree of tightness, described floating headstock by screw pin and floating mount hinged, described screw pin is threaded locking nut.By the degree of tightness of adjusting lock nut, make to float flexibly between floating headstock and floating mount, and can not be too loosening, to ensure floating precision.
Further, described screw pin is also provided with check washer.
The invention has the beneficial effects as follows, bearing ring grinding technique floating support device of the present invention, adopt floating type self adaptation supporting way and ceramic support block, enough support forces are provided and can not leave a trace on lasso surface, without the need to doing repair process again, reducing treatment process, reducing workload, reduce process time, reduce production cost.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Fig. 1 ~ 2, a kind of bearing ring grinding technique floating support device of the present invention, comprise floating mount 1 and the floating headstock 2 hinged with floating mount 1, floating headstock 2 is provided with two for supporting the plane of supporting plane higher than floating headstock 2 of ceramic support block 3, two ceramic support blocks 3 of lasso.Ceramic support block 3 provides radial support power, contacts can not leave a trace on lasso with lasso, also carries out reparation operation with regard to not needing, and reduces treatment process.
Concrete, ceramic support block 3 is cylindrical, the axis being parallel of two cylindrical ceramic back-up blocks 3, and the headstock 2 that floats has the pocket hole that two are installed cylindrical ceramic back-up block 3.
Further, two ceramic support blocks 3 are one in front and one in back arranged in vertical axis direction.
Further, the quantity of the headstock 2 that floats is two, and two floating headstocks 2 are one in front and one in back arranged in pivot center direction, the V-shaped setting of supporting plane of the ceramic support block 3 on two floating headstocks 2.Two floating headstocks 2 can better be fitted lasso surface, provide reliable support force, avoid point cantact.
Further, adjustable for realizing degree of tightness, described floating headstock 2 is hinged by screw pin 4 and floating mount 1, and described screw pin 4 is threaded locking nut 5.By the degree of tightness of adjusting lock nut 5, make to float flexibly between floating headstock 2 and floating mount 1, and can not be too loosening, to ensure floating precision.
Further, screw pin 4 is also provided with check washer 6.
Below introduce the Operation Key of floating support device:
1) connection of " radial support " that the floating mount of floating support device is connected with Machine will guarantee floating precision, float flexibly, and can not too loosening (or having other swing).
2) when a whole set of bracing or strutting arrangement assembled is installed on lathe, must guarantee that the axis of ceramic support block is vertical with magnetic pole end face, namely guarantee axis and the lasso axis being parallel of ceramic support block, to guarantee linear contact lay, adjust and badly also there will be point cantact.
3) installation of lasso on lathe, ajust and put down gently, and impulsive force can not be too large, otherwise ceramic rod may be broken up.
4) spray of grinding fluid will take into account grinding area and Support.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
