Abstract
The utility model provides a thick plate brazing fixture, and mainly solves the problems that the compression strength and the service life of a liquid-cooled module component are affected due to the fact that large deflection and poor weld joint uniformity occur when a cover plate and a frame body are brazed in a vacuum brazing process of the liquid-cooled module component. The thick plate brazing fixture comprises a base plate, wherein an upper pressing part is arranged on a large end surface of the base plate, a processing part is arranged on the other large end surface of the base plate, and a lower pressing device is arranged below the processing part; and clamping devices are distributed on the periphery of the base plate. The combined brazing fixture for the module component is easy and simple to operate, clamping is convenient with a conventional cross screwdriver, and small influences are produced to a subsequent vacuum brazing process after clamping. With the adoption of the combined brazing fixture, the fixture can inhibit deformation of the cover plate and the frame body in vacuum brazing, and deflection of the cover plate and the frame body is compensated to be consistent, so that the welding quality of the module component can be effectively guaranteed.
Description
Technical field

Background technology
Active computer heat transmission liquid cooling modular assembly adopts framework and cover plate to be welded, and forms inner runner, and the framework part is generally thicker, is of a size of about 2 times of cover plate, reaches about 15mm.Cover plate and framework part are because thickness different, in modular assembly vacuum brazing process, there is the alternating hot and cold process, solder fusing, the process of sprawling, solidifying, the thermal deformation of framework and cover plate is inconsistent, as not adopting special grip device, will be because of the inconsistent welding quality that influences of deflection, and finally influence compressive resistance and the service life of liquid cooling modular assembly.In order to suppress the thermal deformation of framework and coverplate parts, even weld unanimity when guaranteeing vacuum brazing guarantees that welding quality needs a kind of reliable and effective device to carry out the clamping of soldering modular assembly soldered component.
Summary of the invention
The utility model provides a kind of slab brazing jig, mainly solved the liquid cooling modular assembly in the vacuum brazing process, meeting when cover plate and framework soldering occurs that deflection is big, even weld is poor, and finally influences the compressive resistance of liquid cooling modular assembly and the problem in service life.
Technical solution of the present utility model is as follows:
This slab brazing jig device comprises for the backing plate of carrying work piece, it is characterized in that: also comprise for the first anchor clamps group of clamping backing plate and work piece main body and be used for the second anchor clamps group at clamping backing plate and work piece edge.
The described first anchor clamps group comprises one to two group of anchor clamps that be arranged in parallel, described anchor clamps comprise compressing member and following compressing member, last compressing member and following compressing member cooperate backing plate and the clamping of work piece main body, last compressing member and backing plate one side fit tightly, backing plate opposite side and work piece one side fit tightly, the work piece opposite side fits tightly with following compressing member, and the vertical range between last compressing member and the following compressing member can be regulated.
Described upward compressing member and following compressing member are not less than the steel plate of 15mm for rectangle steel, I-steel, channel-section steel or the thickness of band installing hole.
The described compressing member of going up passes through screw bolt and nut fit adjustment vertical range with following compressing member.
The described second anchor clamps group comprises three groups of clips that are used for clamping backing plate and work piece edge, two groups of longest edges that are used for clamping backing plate and work piece wherein, and another group is used for an end of clamping backing plate and work piece.
The clip group of the longest edge of described clamping backing plate and work piece, every group comprises at least four uniform clips, the clip group of an end of backing plate comprises at least one clip.
Described clip is fastened on the edge of backing plate and work piece by screw bolt and nut.
Described back plate sizes is that the size of work piece adds 10～20mm.
The utility model advantage is:
This modular assembly combination brazing jig is easy and simple to handle, can be easy to setup with conventional Phillips screwdriver, and less to follow-up vacuum brazing welding process influence behind the clamping.By this built-up jig clamping, anchor clamps suppress the distortion of cover plate and framework during vacuum brazing, and the deflection compensation of cover plate and framework is extremely consistent, and even weld unanimity during the vacuum brazing of control module assembly can effectively guarantee the modular assembly welding quality.
