The to-be-solved technical problem of the utility model is to provide a rational in infrastructure, convenient to use carries out welded heat exchanger equipment with curb plate and core board and bottom plate respectively and uses welding frock.

In order to achieve the above object, the technical solution of the present invention is: the utility model provides a welding frock is used in heat exchanger equipment which characterized in that: including the frock bottom plate, slide locating rack and clamp plate slide locating rack symmetry set up in the frock bottom plate both sides, and the slide locating rack includes slide and socket, and the socket sets up on the slide, and the slide sets up in the frock bottom plate surface, is provided with the backing plate between socket side surface and the clamp plate, and the clamp plate both ends are connected with the socket of bottom plate through the bolt, and the bolt passes clamp plate and backing plate in proper order and is connected with socket side surface detachable.

Further, the surface of the tool bottom plate is provided with a sliding groove for limiting the sliding plate in the sliding groove.

Furthermore, the surface of the sliding groove is provided with a sliding long groove, a guide rod is arranged in the long groove, and the guide rod is connected with the sliding plate.

Furthermore, a C-shaped clamp is additionally arranged on the welding tool, and a clamping opening of the C-shaped clamp is used for clamping and pressing a pressing plate between the inserting openings.

Furthermore, the corners of the two ends of the sliding plate are provided with step notches.

Compared with the prior art, the utility model discloses rational in infrastructure, convenient to use fixes the curb plate through the welding frock, welds the curb plate with core board and bottom plate respectively mutually with welder, can make artifical quick accurate with the curb plate respectively with core board and bottom plate weld the equipment, has effectively reduced the welding deformation among the welding process.

Detailed Description

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

The technical scheme of the utility model is described in detail with the attached drawings, a welding tool for assembling a heat exchanger comprises a tool bottom plate 1, a sliding positioning frame 2 and a pressing plate 3, wherein the sliding positioning frame is symmetrically arranged at two sides of the tool bottom plate and comprises a sliding plate 4 and a socket 5, the socket is arranged on the sliding plate, the sliding plate is arranged on the surface of the tool bottom plate and can slide along the length direction of the tool bottom plate, a backing plate 10 is arranged between the side surface of the socket and the pressing plate, two ends of the pressing plate are connected with the socket of the bottom plate through bolts 6, the bolts sequentially pass through the pressing plate and the backing plate and are detachably connected with the side surface of the socket, when a core body with a core body plate 12 is welded on the bottom plate 13 first, when the side plate 14 is required to be respectively welded with the core body plate and the bottom plate, the bottom plate is placed on the surface of the, the sliding plate is abutted against the bottom plate and fixed on the surface of the tool bottom plate, the bottom plate is placed on the tool bottom plate, in order to facilitate positioning, a sliding groove 7 is arranged on the surface of the tool bottom plate to limit the sliding plate in the sliding groove, the sliding plate can slide along the length direction of the sliding groove on the tool bottom plate, the sliding of the sliding plate is facilitated, the bottom plate is also conveniently and accurately positioned on the tool bottom plate, a sliding long groove 8 is arranged on the surface of the sliding groove, a guide rod 9 is arranged in the long groove and is connected with the sliding plate, so that the sliding plate can accurately slide linearly when sliding, after the bottom plate is positioned, the side plate is placed between the core plate and the bottom plate, the end part of the side plate is attached to the side surface of the socket, the pressing plate is connected with the side surface of the socket through a bolt, the side plate is jointly extruded through the side surface of the, after the side plates are fixed, the side plates are welded with the core body plate and the bottom plate respectively by using a welding gun, and are quickly and accurately welded and assembled, so that the welding deformation in the welding process is effectively reduced.

When the length of needs welded curb plate is longer, only can only extrude the tip of curb plate through the extrusion of clamp plate and socket, and the pressure that the middle part of curb plate often received is less can produce bending deformation, add on the welding frock and be equipped with C type anchor clamps 11, the mouth that presss from both sides of C type anchor clamps is used for the clamp plate between the nip socket, C type anchor clamps can be according to the different length of curb plate, suitably increase or reduce quantity, exert pressure to the clamp plate through pressing from both sides the mouth, the clamp plate is with pressure transmission to curb plate, make curb plate and core tightly laminate, the effectual deformation that has prevented the curb plate, the edge at slide both ends is provided with step breach 15, after the bottom plate is withstood to the slide, the step breach that sets up makes things convenient for placing of.
