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, particularly relates to double-row bearing retainer elastic positioner, for ensureing during retainer bore hole that biserial pocket hole in two sides two is interspersed and can accurately locates anyway, belongs to design of technological arrangement field.
Background technology
double-line spherical roller bearing hold frame is designed to pocket hole, two sides, require that a side pocket hole is in the centre in adjacent two the pocket holes of opposite side, common processing mode is after first surface first row pockets processing terminates, during processing secondary series pocket hole, general employing experience ocular estimate measures the bore hole position of second secondary series, often because pocket hole site, two sides error causes the generation of waste product; The feature of this type of spherical bearing retainer:
(1) pocket hole is unconventional shape, is a curved surface in the middle of the retainer that particularly high-precision bearing uses, due to pocket hole by multiple straight line, curve, face directly, cambered surface etc. forms, locating surface is not easily determined;
(2) two row retainers are interspersed, and vary in size according to retainer, and the dislocation of its two row pocket hole need be less than 0.3-0.8mm.
Summary of the invention
in view of the technological gap that prior art and product exist, the object of this invention is to provide a kind of double-row bearing retainer elastic positioner, after solving double-row bearing retainer boring complete first surface pocket hole, used for locating pocket hole site during second time boring second pocket hole, once mounting forever uses, convenient operation, raises the efficiency, and can process satisfactory retainer.
To achieve these goals, the technical solution adopted in the present invention is: double-row bearing retainer elastic positioner, it is characterized in that comprising locating piece, positioning body, spring, screw and workpiece; Described locating piece top is locating surface, and locating surface is provided with spring eye, is provided with connecting hole in spring eye both sides, and spring fitting is in positioning body bottom, and positioning body puts into the spring eye in locating piece, and screw is arranged in connecting hole.
Described positioning body upper surface exceeds locating piece locating surface.
Described screw head height flushes with locating piece locating surface or lower than locating piece locating surface.
Described face, locating piece inner side and outer side is arc locating surface, adopts the processing of high-precision wire cutting off machine, ensures the precision of arc locating surface, and the internal-and external diameter of itself and retainer pockets processing fixture is matched.
Add man-hour, positioning body is installed in locating piece, and when processing retainer first surface pocket hole, retainer other end is locating surface, and is plane, is subject to object pressure, in positioning body retraction locating piece, can not cause interference to processing; When processing second, with the first surface processed for locating surface, locating surface becomes the interrupted locating surface having pocket hole, positioning body is upspring by the effect of spring, enter into the pocket hole processed, higher than the large plane of pockets processing fixture seam, the arbitrary pocket hole inwall on workpiece is near positioning body, can fixation workpiece position, complete second pockets processing.
Compared with machining and additive method, have the following advantages: this positioning device structure is simple, low cost of manufacture; Production efficiency is high, and simple to operate; Processing effect is good, and its location is very accurate, and deviation is at 0.1-0.2mm; Pocket hole, all two sides can be applied to and have the retainer Product processing of relative position requirement.

Detailed description of the invention
below in conjunction with accompanying drawing, the present invention is described in detail.
Double-row bearing retainer elastic positioner, is characterized in that comprising locating piece 1, positioning body 2, spring 3, screw 4; Described locating piece 1 top is locating surface 7, and locating surface 7 is provided with spring eye 5, is provided with connecting hole 6 in spring eye 5 both sides, and spring 3 is arranged on positioning body 2 bottom, and positioning body 2 puts into the spring eye 5 in locating piece 1, and screw 4 is arranged in connecting hole 6.
Described positioning body 2 upper surface exceeds locating piece locating surface 7.
Described screw 4 tip height flushes with locating piece locating surface 7 or lower than locating piece locating surface 7.
Described face, locating piece 1 inner side and outer side is arc locating surface, adopts the processing of high-precision wire cutting off machine, ensures the precision of arc locating surface, and the internal-and external diameter of itself and retainer pockets processing fixture is matched.
Locating piece 1 is fixed on retainer pockets processing fixture by two screws 4, and during processing first surface pocket hole, be pressed into by positioning body 2 in locating piece 1, workpiece and retainer pockets processing holder contacts, machine.Turn-over processing secondary series pocket hole, now positioning body 2 is by the effect of spring 3, and eject locating piece 1, any one pocket hole inwall of the first row of workpiece, abuts against on positioning body 2, fixation workpiece, completes second processing.
