Abstract
The invention discloses a positioning device, and particularly relates to an elastic positioner for double-row bearing retainers. The elastic positioner comprises a positioning block, a positioning body, a spring, screws and workpieces. A positioning surface is arranged on the upper portion of the positioning block, a spring hole is formed in the positioning surface, connecting holes are formed in two sides of the spring hole, the spring is mounted on the lower portion of the positioning body, the positioning body is arranged in the spring hole of the positioning block, and the screws are arranged in the connecting holes. The elastic positioner has the advantages that the elastic positioner which is a positioning device is simple in structure and operation, low in manufacturing cost and high in production efficiency; excellent machining effects can be realized, the workpieces can be quite accurately positioned by the elastic positioner, and the deviation ranges from 0.1mm to 0.2mm; the elastic positioner can be popularized and can be applied to machining all retainer products with requirements on relative positions, and pockets are arranged on two surfaces of each retainer product.
Description
Technical field
The present invention designs a kind of positioner, relates particularly to double-row bearing retainer elastic positioner, for bearing
Ensure during retainer bore hole that two sides two biserial pocket hole is interspersed and can be accurately positioned anyway, belongs to design of technological arrangement field.
Background technology
Double-line spherical roller bearing hold frame is designed as two sides pocket hole it is desirable to a side pocket hole is in opposite side two neighboring pocket hole
Centre, after common processing mode terminates for the first face first row pockets processing, processing secondary series pocket hole when, typically adopt warp
Test the bore hole position that ocular estimate measures the second face secondary series, often because two sides pocket hole site error leads to the generation of waste product；This
The feature of class spherical bearing retainer：
(1) pocket hole is unconventional shape, is a curved surface, due to pocket hole in the middle of the retainer that particularly high-precision bearing uses
By multiple straight lines, curve, face directly, cambered surface etc. forms, locating surface is difficult to determine；
(2) two row retainers are interspersed, of different sizes according to retainer, and the dislocation of its two row pocket hole need to be less than 0.3-
0.8mm.
Content of the invention
A kind of in view of technological gap that prior art is existed with product, it is an object of the invention to provide double-row bearing retainer
Elastic positioner, after solving the complete first face pocket hole of double-row bearing retainer boring, for positioning pocket hole during the pocket hole of second boring the second face
Used by position, once mounting forever uses, and is easy to operate, improves efficiency, can process satisfactory retainer.
To achieve these goals, the technical solution adopted in the present invention is：Double-row bearing retainer elastic positioner, its
It is characterised by including locating piece, positioning body, spring, screw and workpiece；Described locating piece top is locating piece locating surface, fixed
Position block locating surface is provided with spring eye, is provided with connecting hole in spring eye both sides, spring is arranged on positioning body bottom, positioning body is put into
In the spring in the hole of locating piece, screw is arranged at connection in the hole.
Described positioning body upper surface exceeds locating piece locating surface.
Described screw head height and locating piece locating surface are flush or below locating piece locating surface.
Described locating piece inner side and outer side face is arc locating surface, using the processing of high-precision wire cutting off machine it is ensured that arc
The precision of shape locating surface is so as to match with the internal-and external diameter of retainer pockets processing fixture.
During processing, positioning body is installed in locating piece, and when processing retainer the first face pocket hole, retainer other end is
Locating surface, and be plane, by object pressure, in positioning body retraction locating piece, processing will not be caused interfere；Processing second
During face, with the first machined face as locating surface, locating surface is to become the interrupted locating surface having pocket hole, and positioning body passes through spring
Effect upspring, enter in machined pocket hole, higher than the big plane of pockets processing fixture seam, the arbitrary pocket in the hole on workpiece
Wall, against positioning body, can fix the location of workpiece, completes the second face pockets processing.
Compared with machining and additive method, there is advantages below：This positioning device structure is simple, low cost of manufacture；
Production efficiency is high, and simple to operate；Processing effect is good, and its positioning is very accurate, and deviation is in 0.1-0.2mm；Can be applicable
In all two sides pocket hole and have relative position require retainer Product processing.

Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
Double-row bearing retainer elastic positioner is it is characterised in that include locating piece 1, positioning body 2, spring 3, screw 4；Institute
Locating piece 1 top stated is locating piece locating surface 7, is provided with spring eye 5, is provided with spring eye 5 both sides on locating piece locating surface 7
Connecting hole 6, spring 3 is arranged on positioning body 2 bottom, and positioning body 2 is put in the spring eye 5 of locating piece 1, screw 4 company of being arranged at
Connect in hole 6.
Described positioning body 2 upper surface exceeds locating piece locating surface 7.
Described screw 4 tip height and locating piece locating surface 7 are flush or below locating piece locating surface 7.
Described locating piece 1 inner side and outer side face is arc locating surface, using the processing of high-precision wire cutting off machine it is ensured that arc
The precision of shape locating surface is so as to match with the internal-and external diameter of retainer pockets processing fixture.
Locating piece 1 is fixed on retainer pockets processing fixture by two screws 4, during processing the first face pocket hole, will determine
In the body 2 press-in locating piece 1 of position, workpiece and retainer pockets processing holder contacts, machine.Turn-over processes secondary series pocket hole,
Now positioning body 2 passes through the effect of spring 3, ejects locating piece 1, any one pocket in the hole wall of the first row of workpiece, and it is fixed to abut against
On the body 2 of position, fixing workpiece, complete the second face processing.
