Specific embodiment
As shown in Figure 1 and Figure 2, a kind of positioning fixture of double-pipe joint described in the utility model embodiment, including bottom plate 1,
Vertical plate 2, bottom plate 1 are fixedly connected with vertical plate 2, and bottom plate 1 is fixed on above workbench, and vertical plate 2 is machined with through-hole 22 and length at middle part
Slot 21, through-hole 22 are located above;Rotational positioning part 5 is installed at through-hole 22 and equipped with copper sheathing 4, and the outer end of rotational positioning part 5 is
The section of positioning head 6, positioning head 6 is equilateral triangle, and the edge of equilateral triangle is rounded down;Upper guide-localization part 7 is fixed on
The upper surface middle part of vertical plate 2, the middle part of upper guide-localization part 7 process perforative pilot hole 71, install insulator in pilot hole 71, on
The outside protrusion of guide-localization part 7 forms positioning region 72;Lower locating rod 3 is fixed at elongated slot 21, and the middle part of lower locating rod 3 is positive
Hexagonal prisms, bull stick 10 are screwed in the outer end of lower locating rod 3, and balancing pole 11 is fixed on the lower part of bull stick 10;Holding screw 8, which is threaded onto, to be turned
The top of bar 10, the end of holding screw 8 are further fixed on handle 9, and the center line of holding screw 8 and the center of through-hole 22 are same
In height.
The precise positioning of double-pipe joint is realized by this positioning fixture, while this positioning fixture is to fix on the table
, mesoporous and side opening can be processed on double-pipe joint by the up and down motion of drilling device, for artificial drilling,
Accurate positioning, it is convenient to operate.
When specifically used, the utility model is understood for convenience, is described in conjunction with attached drawing;
It processes mesoporous: as shown in Figure 8, Figure 9, when processing mesoporous 123, being first bonded double-pipe joint with the outside wall surface of vertical plate,
At this point, rotational positioning part is embedded into the inner cavity of double-pipe joint, meanwhile, the lower surface of positioning region 72 and the positive of double-pipe joint position
Face 125 contacts, so, the position of double-pipe joint is determined, it rotates on bull stick to vertical line direction, and screw holding screw 8,
Later, drill bit is directed on double-pipe joint through pilot hole 71 by top and processes mesoporous 123.
It processes side opening: as shown in Figure 10, when processing side opening, first double-pipe joint being bonded with the outside wall surface of vertical plate equally, is made
Rotational positioning part is embedded into the inner cavity of double-pipe joint, by rotating double-pipe joint, is brought to abutment against positive the six of lower 3 middle part of locating rod
On prism, after the position of double-pipe joint is determined, then locked by holding screw 8, drill bit is directed at by top through pilot hole 71
Side opening 124 is processed on double-pipe joint.
Wherein, lower locating rod can on elongated slot appropriate adjustment height and position so that device be suitable for certain size within the scope of
Double-pipe joint positioning.
