Abstract
The invention relates to the technical field of bearing machining, in particular to a precision positioning device for machining a roller limiting hole of a square pocket hole holder. The precision positioning device comprises a location table and a location block, and the precision positioning device is that a location table seat is arranged on the location table, the holder and the location table are fixed through the location table seat which is fixed on a drill machine, the location block is installed on the location table seat, a location hole is arranged on the location table seat, and the location block can be conveniently installed through the location hole. The precision positioning device enables a limiting hole to achieve size accuracy, enables location to be accurate, can avoid position error caused by different dimensional deviations of a pocket hole, accordingly solves technological problems that a square pocket hole product of the holder processes the limiting hole of an rolling element, and can accurately guarantee rotation positions and pitch circle core distance of the rolling element in a bearing. A machining location mode of the precision positioning device can be simultaneously applicable to other machining fields similar to the product structure.
Description
Technical field
The present invention relates to technical field of bearing processing, it is concretely the spacing hole machined of bearing square pocket keeping rack retainer roller
Positioner.
Background technology
There is a kind of retainer, pocket hole is square, the retainer of this square pocket keeping rack, after rolling element loads,
In the contact process of cylindrical rolling element and square pocket keeping rack, the degree of freedom ratio of roller is larger, in order to control the play of rolling element
Amount, in the middle of retainer square pocket keeping rack, that is, on the centrage of square pocket keeping rack, is also on the centre of gyration line of rolling element, bores
One roller spacing hole, this spacing hole, in assembling, is simultaneously charged into spacer pin, and requires spacer pin to be accurately positioned at roller
On centrage.So can ensure that rolling physical ability enters the revolution of correct raceway, due to the presence of pin makes rolling element can not be with
Meaning vibration is it is ensured that the uniform gap in rolling element and retainer pocket hole.The new construction bearing of this advanced design in the world keeps
Frame is it is ensured that the proper alignment of spacing hole and symmetry difficulty are very big.Mainly between two side walls of retainer square pocket keeping rack
The spacing hole boring, positional precision cannot ensure.In addition retainer is after square pocket keeping rack machines, due to the entity portion of retainer
Divide and be greatly decreased, retainer produces contraction distortion, be further continued for boring spacing hole, retainer will occur bigger contraction distortion, produce
All there is very big change in the form and position tolerances such as the perpendicularity of product, taper.Square hole etc. point is poor, size is inclined to also have this precision can be subject to
The impact such as difference, also can be affected by tool precision, therefore, using traditional process technology it is difficult to ensure that product quality requires.
Content of the invention
In view of the defect that prior art exists, the mesh of the present invention is to provide a kind of square cage pocket roller spacing hole to add
The precision positioning device of work, this device ensure that spacing hole reaches dimensional accuracy, can solve to process this constitutional detail
Technical barrier.
For achieving the above object, the present invention solves by the following technical programs：Square cage pocket roller is spacing
The precision positioning device of hole machined, including positioning table, locating piece；It is characterized in that positioning table is provided with positioning pedestal, retainer with
Fixed with positioning table by positioning pedestal, positioning pedestal is fixed on boring machine, locating piece is arranged on positioning pedestal, in positioning
Pedestal is provided with location hole, and location hole is easily installed locating piece.
Described locating piece is taper cube structure, and it is smaller in size than 0.05 0.1 millimeters of retainer square hole, and taper is
0.5 degree.
Depending on described positioning block size is with retainer square pocket keeping rack size, big end size is more than retainer square pocket keeping rack chi
Very little, small end is smaller in size than square pocket keeping rack size.
Described locating piece four side junction is in rounding off, and surface roughness ensures in Ra0.4um.
Retainer is fixed on Special drill machine, is axially positioned by boring machine, can carry out 360 degree of scopes by decile and return
Turn.Radially adopt taper locating piece positioning, locating piece is arranged on positioning pedestal, when retainer often moves a decile, taper
Locating piece overturns, and locating piece is properly inserted in square pocket keeping rack, is positioned.
Further, the present invention positions to accomplish gapless, and locating piece small end smoothly can enter square pocket keeping rack, big end
Combine closely with square pocket keeping rack.
The beneficial effects of the present invention is：Taper cube positioner, ensure that spacing hole reaches dimensional accuracy；Fixed
Level is true, and the position error causing not of uniform size that square pocket keeping rack can be overcome to produce because of dimensional discrepancy therefore, solves holding
The technological difficulties of frame square pocket keeping rack Product processing rolling element spacing hole, accurately ensure rolling element rotary position within the bearing and
The heart of pitch circle away from.Locating and machining mode of the present invention, is equally applicable to be similar to other manufacture fields of this product structure.
