Abstract
The utility model provides an optical fiber ferrule polishing fixture, which comprises a fixture body (10), a press plate (20) and bolts (30), wherein, the bottom surface of the fixture body (10) is provided with a groove (11) and bolt holes (12); the press plate (20) is tabular and provided with through holes (21); the bolts (30) are screwed in the bolt holes of the fixture body through the through holes (21); the end of the press plate (20) is fixedly connected with the fixture body (10). When the fixture works, the press plate (20) is tightened and fixed with the middle of the fixture body (10) through the bolts (30), which will certainly cause the part to be distorted. As the end of the press plate (20) is fixed with the fixture body (10), the press plate (20) is bent, which generates rigid restoring force. After the processing, the bolts are unscrewed; the press plate (20) is restored to the original state by the rigid restoring force, thus avoiding deformation.
Description
Technical field
The utility model relates to process equipment, particularly is used for the anchor clamps of attrition process fiber stub.
Background technology
Be used for the anchor clamps that fiber stub grinds in the prior art, general all is that pressing plate is (as shown in Figure 1) of separating with chuck body, the anchor clamps of this split are convenient to processing, also can reduce die manufacturing cost, but, this split anchor clamps in use also exist some problems, especially for pressing plate, because this pressing plate tightens fixing by middle bolt and chuck body, and its two ends are in free state, after long-term the use, cause pressing plate distortion itself easily, after the pressing plate distortion, the center line that is sandwiched in the fiber stub between chuck body groove and the pressing plate is departed from, fiber stub after the grinding, the center line of the center line of its round end and fiber stub cylinder part can not coincide, and off-set phenomenon takes place.The fiber stub of this off-centre is used for the joints of optical fibre, will cause two sections optical fiber contrapositions of connection inaccurate, has influence on the transmission efficiency of light.
Summary of the invention
The utility model provides a kind of fiber stub grinding clamp, adopt pressing plate and the incorporate method of chuck body, the two ends of pressing plate are fixed up, prevent that pressing plate is out of shape, improve grinding precision, grind the technical problem that deviation takes place easily for bulb and fiber stub cylinder center line in the solution prior art.
A kind of fiber stub grinding clamp comprises
One chuck body, the bottom surface of this chuck body is provided with groove and screw;
Pressing plate is tabular, and this pressing plate is provided with through hole;
Bolt, this bolt pass in the screw of through hole screw-in chuck body on the pressing plate;
Fixedly connected with chuck body in the end of described pressing plate.
Described pressing plate end is that integral type is connected, is welded to connect or bolt connects with chuck body.
Described pressing plate comprises first pressing plate and second pressing plate, and described bolt comprises first bolt and second bolt; Described through hole is for being located at free-ended first through hole of first pressing plate and second pressing plate and second through hole respectively; Described screw also comprises first screw and second screw; One end of described first pressing plate and second pressing plate is fixedlyed connected with chuck body, and the other end of described first pressing plate and second pressing plate is by first bolt and second bolt and first screw and second screw and chuck body flexible connection.
After the utility model adopts technique scheme, because pressing plate two ends and chuck body are fixed, under pressing plate work stress itself, these two supports have formed fixed structure concerning the pressing plate stress point, make stress point be similar to free end in the cantilever beam, it is had than higher elasticity and recovery capability, so this grinding clamp has higher anti-deformation, also just improve the quality that fiber stub grinds, guaranteed the precision of workpiece.
Description of drawings
The in running order schematic diagram of anchor clamps in Fig. 1 prior art.
Fig. 2 a-c is the schematic diagram that the utility model pressing plate is connected with chuck body.
Fig. 3 is the working state schematic representation that the utility model adopts two block pressur plates.
Fig. 4 is the working state schematic representation that the utility model adopts the monolithic pressing plate.
Fig. 5 a-b is that the utility model adopts single pressing plate list bolt or two working bolt view.
The specific embodiment
In conjunction with above-mentioned description of drawings specific embodiment of the utility model.
By among Fig. 2 a as can be known, this fiber stub grinding clamp comprises
One chuck body 10, the bottom surface of this chuck body 10 are provided with groove 11 and screw 12;
Fixedly connected with chuck body 10 in the end of described pressing plate 20.
Under clamp working-station, this bolt 30 tightens the middle part of pressing plate 20 and chuck body 10 fixing, certainly will make this part produce distortion, because the end of pressing plate 20 and chuck body 10 are fixing, make the middle force part of pressing plate 20 form cantilever beam structures or be similar to cantilever beam structures, pressing plate 20 has formed a kind of bending shape, at this moment, pressing plate 20 has produced the rigidity restoring force, when completion of processing is unclamped bolt, this rigidity restoring force makes pressing plate 20 recover reset condition, has also just restrained distortion.
By among Fig. 2 a-c as can be known, described pressing plate 20 ends are connected, are welded to connect for integral type with chuck body 10 or bolt connects, welding or bolt connect is convenient to processing more, the processing cost that can save anchor clamps, and the connection of integral type, then non-deformability is stronger.
By among Fig. 3 as can be known, described pressing plate 20 comprises first pressing plate 21 and second pressing plate 22, described bolt 30 comprises first bolt 31 and second bolt 32; Described through hole 21 is for being located at first pressing plate 21 and second pressing plate, 22 free-ended first through hole 211 and second through holes 221 respectively; Described screw 12 also comprises first screw 121 and second screw 122; One end of described first pressing plate 21 and second pressing plate 22 is fixedlyed connected with chuck body 10, and the other end of described first pressing plate 21 and second pressing plate 22 is by first bolt 31 and second bolt 32 and first screw 121 and second screw 122 and chuck body 10 flexible connections.Adopt the mode of double clamp, be convenient to clamp for machining, cut down finished cost.
By among Fig. 4 as can be known, described pressing plate 20 is a whole plate, the fixedly connected chuck body 10 in the two ends of this pressing plate 20, its middle part flexibly connects by bolt 30 and chuck body 10.
By among Fig. 4 as can be known, described groove 11 comprises first groove 111 and second groove 112, fiber stub M of each clamping, described groove 11 is triangle, rectangle, semicircle or polygon.Pressing plate 20 is provided with groove 40 with chuck body 10 places, this groove 40 not only can reduce the stress of this junction and concentrate, and can make pressing plate 20 strengthen elasticity, and improving its non-deformability, this can adopt circular arc or other can reduce stress and concentrate, increases briquetting 20 flexible other shapes.
By among Fig. 5 a-b as can be known, bolt 30 can adopt one, described screw 12 is single screw 123, the through hole 21 on the described pressing plate 20 also is one.Also can adopt two, described screw 12 is two screws, and the through hole 21 on the described pressing plate 20 also is two.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
