Abstract
The utility model aims to provide a fixture capable of distributing and closely lining 7 composite billet bars in a hexagonal shape to ensure the bundled and fixed composite billet bars do not have relative displacement and deflection so as to improve the drawn multifilament quality and meets the quality requirements on transmitted images. The composite billet bar bundling fixture for drawing the optical fiber multifilament comprises at least one pair of bar installation fixtures consisting of an upper fixture and a lower fixture; and the upper fixture and the lower fixture are respectively provided with V-shaped grooves which are over against and form a 60-degree angle.
Description
Technical field
The utility model relates to a kind of compound base rod that is used for the drawing optical fiber multifilament and ties up anchor clamps, specifically, is a kind of instrument that 7 compound base rods will being used for the drawing optical fiber multifilament are bundled into regular hexagon (sexangle in other words).
Background technology
In the pulling process of traditional fiber multifilament, be used for the compound bases rod of 7 of drawing optical fiber multifilament and with steel wire two ends tied up earlier fixingly, be contained in the outer tube together then.When tying up, 7 compound base rods will be bundled into regular hexagon (sexangle in other words).But when tying up compound base rod with manual mode commonly used, owing to have the gap between the compound base rod, be difficult to guarantee that 7 compound base rods can be by closely arrangement of sexangle distribution, between the compound base rod relative displacement and deflection are arranged when causing drawing, directly influence the optical fiber multifilament quality that draws out, thereby can not satisfy the requirement of transmission picture quality.
The utility model content
The purpose of this utility model provide a kind of can be with 7 compound base rods by the sexangle compact arranged anchor clamps that distribute, tie up no relative displacement and deflection between the compound base rod that fixes with assurance, thereby the optical fiber multifilament quality that raising draws out is to satisfy the requirement of transmission picture quality.
Originally the compound base rod that is used for the drawing optical fiber multifilament is tied up anchor clamps, comprises at least one pair of dress rod clamp of being made up of last anchor clamps and lower clamp, is respectively equipped with relative angle on last anchor clamps and the lower clamp and becomes 60 ° vee-cut.
During use, all place a pole (two ends of the compound base rod that is tied exceed the two ends of pole) with the compound base rod equal diameters that is tied in the angle of the vee-cut of last anchor clamps and lower clamp, then 7 compound base rods are placed between anchor clamps and the lower clamp, in two formed spaces of relative vee-cut, it is involutory the clamping of 7 compound base rods to go up anchor clamps and lower clamp, the two ends of compound base rod is tied up to get final product then.
The beneficial effects of the utility model: tie up compound base rod with traditional manual mode and compare, use these anchor clamps to distribute 7 compound base rods by sexangle and closely arrange, make and tie up no relative displacement and deflection between the compound base rod of fixed.
If have only a pair of anchor clamps and the lower clamp gone up, when being placed on 7 compound base rods in the formed space of vee-cut relative between anchor clamps and the lower clamp, because last anchor clamps and lower clamp are equivalent to a fulcrum, 7 compound base rods are stable, tilt easily, conduct is to above-mentioned improvement of tying up the anchor clamps of compound base rod for this reason, and the dress rod clamp is two pairs.Certainly, to place the loaded down with trivial details of pole when tying up in order saving at every turn, to be arranged on two with the pole of the compound base rod equal diameters that is tied and to go up anchor clamps or/and the angle of the vee-cut of lower clamp, the two ends of the compound base rod that is tied exceed the two ends of pole.In order to change the relative position of two pairs of dress rod clamps fast, it also comprises a guide rail, two guide rail slide blocks that are slidingly arranged on the guide rail, and two pairs of last anchor clamps or lower clamps of adorning in the rod clamp are separately positioned on two guide rail slide blocks.
Last anchor clamps and lower clamp ways of connecting have many, and for example, last anchor clamps and lower clamp in a pair of dress rod clamp are located with steady brace, pass through screw retention.
Description of drawings
Fig. 1 is a kind of front view of tying up the anchor clamps of compound base rod;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a dress rod clamp synoptic diagram.
Embodiment
Referring to a kind of anchor clamps of tying up compound base rod shown in Fig. 1,2, it comprises guide rail 1, guide rail slide block 2a, the 2b of linear slide on guide rail 1, two lower clamp 8a, 8b that are separately fixed on guide rail slide block 2a and the 2b, two last anchor clamps 3a, 3b that difference can cooperate with lower clamp 8a, 8b.Lower clamp partners with the last anchor clamps that cooperate and adorns rod clamp 38.
Referring to Fig. 3, last anchor clamps are provided with the vee-cut 9 that relative angle becomes 60 °.Lower clamp is provided with the vee-cut 10 that angle becomes 60 °.The opening of vee-cut 10 is greater than the opening of vee-cut 9, and the opening of vee-cut 9 stretches in the opening of vee-cut 10.
Last anchor clamps in a pair of dress rod clamp and lower clamp are with two steady braces, 7 location, and be fixing by two screws 6.What steady brace 7 guaranteed to go up anchor clamps and lower clamp repeats to install bearing accuracy.Last anchor clamps and lower clamp tighten up by screw 6, guarantee to clamp upward anchor clamps and the compound base rod of lower clamp intermediary (the compound base rod that is tied) 4 and pole 5a, 5b.
During use,, be positioned in the vee-cut 10 of lower clamp, will go up the vee-cut 10 corresponding installations of anchor clamps vee-cut 9 and lower clamp then, locate and tighten up by steady brace 7 and screw 6 with each 1 of 7 compound bases rods 4 and pole 5a, 5b.Pole 5a is in the angle of vee-cut 9, and pole 5b is in the angle of vee-cut 10.
Wherein, the diameter of compound base rod 4 and pole 5a, 5b is identical, and the two ends of compound base rod 4 exceed the two ends of pole 5a, 5b.
At last, it is fixing to adopt steel wire that two ends are tied up 7 compound base rods 4 that clamp, and unclamps screw 6, takes off anchor clamps 3, takes off 7 compound base rods 4 tying up, promptly can be used for drawing multifilament.
Because the diameter of compound base rod 4 and pole 5a, 5b is identical, be clamped in again in 60 ° of corresponding vee-cuts, therefore can guarantee that compound base rod is to distribute compact arranged by sexangle, no relative displacement and deflection between the compound base rod, thereby the multifilament quality that assurance draws out is to satisfy the requirement of transmission picture quality.
