Description
Technical field:
The utility model relates to a kind of fixture, particularly a kind of plate-fin heat exchanger positioning fixture for welding.
Background technology:
The installing plate that heat exchanger in auto air-con comprises core body and is connected with core body, core body and installing plate are split part, integral by being welded to connect, and the position dimension of the installing hole wherein on installing plate requires higher, can assemble smoothly when installing with main frame.Specification due to auto air-con has multiple, normally a kind of air-conditioning need manufacture and design a set of special positioning fixture for welding, its advantage is, very fast during welding assembly again, welding is short with non-cutting time, but the expense of the design of fixture, manufacture is much larger than the expense of non-cutting time, and storehouse area occupied is large.
Summary of the invention:
The utility model object is to provide a kind of design, manufacturing expense is low and take the few a kind of plate-fin heat exchanger positioning fixture for welding of warehouse area.
The technical solution of the utility model is, a kind of plate-fin heat exchanger positioning fixture for welding, comprise base plate and location-plate, it is characterized in that: described base plate transversely with is longitudinally evenly equipped with the equal screwed hole of pitch of holes, the perpendicular side edge of square movable fixed head respectively has an orthogonal bar shaped elongated hole, the length of this bar shaped elongated hole is greater than the distance between adjacent two screwed holes on described base plate, its width is the external diameter with the screw of the corresponding threaded holes on base plate, movable fixed head is provided with diagonal two bar shaped elongated holes are segmented in both sides, this diagonal is provided with the equal locating hole of three pitchs of holes, above-mentioned movable fixed head is three and is separately fixed at three angles place of base plate with screw, a movable positioning plate is made up of a square location-plate and two bar shaped location-plates, these two bar shaped location-plates are mutually vertical and flush with orthogonal two sides of square location-plate, a diagonal of described square location-plate is provided with the equal locating hole of three pitchs of holes, and two perpendicular bar shaped location-plates are divided into both sides by this diagonal, the elongated hole that the bar shaped location-plate of described movable positioning plate is provided with level is relative with two horizontal threaded bore on described movable fixed head end face, three movable fixed heads and movable positioning plate place the platform of welded piece by composition one on screw fixed base plate, and three movable fixed heads are with movable positioning plate diagonal respectively to have a locating hole relative with the installing hole on welded piece.
The utility model have compared with the prior art manufacture and design expense low, take the advantage that warehouse area is few, be particularly suitable for small lot batch manufacture.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model; Fig. 2 is the top view of Fig. 1.
Detailed description of the invention:
The utility model has following embodiment, positioning fixture for welding of the present utility model comprises base plate, movable fixed head 5 and movable positioning plate 2, base plate 1 is square plate, horizontal and vertical on this base plate is evenly equipped with screwed hole, lateral separation between each screwed hole is identical with fore-and-aft distance, as 50mm, described movable fixed head is square plate, a bar shaped elongated hole 6 is respectively established to parallel with side respectively at the dual-side place that this movable fixed head is adjacent, the length of this bar shaped elongated hole is greater than the distance of adjacent two screwed holes uniform on above-mentioned base plate, its width should be able to place the screw 4 with described corresponding threaded holes, a pair linea angulata of above-mentioned movable fixed head is provided with three equal locating holes 7 of pitch of holes, on movable fixed head a two bar shaped elongated hole is segmented in both sides by this diagonal, the structure of described movable positioning plate 2 is, be bar shaped location-plate at the perpendicular dual-side of square location-plate, the diagonal of above-mentioned square location-plate is provided with three locating holes that pitch of holes is equal, and orthogonal two bar shaped location-plates are segmented in both sides by this diagonal.The thickness of above-mentioned movable fixed head is equal with the thickness of movable positioning plate, two screwed holes end face of the stripe board of described movable positioning plate is provided with on bar shaped long spiro nail 3 via hole and described movable fixed head end face are relative, and its length is greater than the distance between two screwed holes on movable fixed head end face.
Using method of the present utility model is, first each 2 of 4 screws in the angle place (upper left corner) movable fixed head being placed on base plate are placed in two bar shaped elongated holes respectively and are fixed on base plate with the screwed hole of base plate, then in the size of transverse direction, the 2nd movable fixed head is screwed in base plate upper right side by product, 3rd movable fixed head be screwed lower right at base plate by product in the size of longitudinal direction, finally the square fixed head of movable positioning plate is placed on the lower left of base plate, the inner side end of orthogonal two stripe board of this movable positioning plate is made to lean against on a side end face of described base plate upper left side and bottom-right movable fixed head, connect as one with it with screw 3, last pin inserts in the dowel hole of the movable fixed head on welded product and base plate, just can weld.
