Description

Technical Field

[0001] This utility model relates to the technical field of brazing fixtures, and in particular to a novel general-purpose brazing assembly CAB brazing fixture. Background Technology

[0002] Brazing fixtures are essential auxiliary tools in the brazing process, used to precisely and stably fix the parts (base materials) to be joined during heating and cooling, and to ensure that they maintain the correct position and gap, thereby obtaining high-quality brazed joints.

[0003] Existing brazing fixtures, such as the brazing fixture for copper-clad laminates disclosed in utility model patent application number 202420599442.1, mainly include multiple clamping plates and multiple locking components. At least one of two adjacent clamping plates is provided with a limiting groove with an opening facing the other clamping plate. The limiting groove is used to place the copper foil of the copper-clad laminate to limit the copper foil. The multiple locking components are used to lock and fix the multiple clamping plates and the copper-clad laminate together. During assembly, the locking bolts are passed through the bolt holes on each clamping plate in sequence, and then the locking nuts are screwed onto the locking bolts to press the copper-clad laminate between the two adjacent clamping plates.

[0004] However, most existing brazing fixtures can only hold a single product, making it inconvenient to transfer between the upper and lower brazing furnaces. Furthermore, they cannot be adapted to multiple valve plates, limiting their applicability. Consequently, a large number of specialized fixtures need to be manufactured, increasing production costs. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a new type of universal brazing assembly CAB brazing fixture that can not only adapt to the brazing of multiple valve plates by adjusting the pressure head hole position, thus reducing manufacturing costs, but also has a simple locking mechanism that is easy to operate manually. It can load three products at the same time, reducing the number of manual transfers and lowering costs.

[0006] This utility model discloses a novel general-purpose brazing assembly CAB brazing fixture, which includes a support mechanism and three sets of clamping mechanisms. The three sets of clamping mechanisms are all installed on the support mechanism and clamp the valve plate. The manually assembled valve plate and brazing plate are placed on the support mechanism, and the clamping mechanisms are rotated to press down, which facilitates subsequent brazing. By setting three sets of clamping mechanisms, it is convenient to clamp three sets of products at the same time.

[0007] Preferably, the support mechanism includes a clamp base, three sets of graphite plates, three sets of fixed brackets, and six sets of limiting brackets. The bottom end of the clamp base is placed on the working surface. All three sets of graphite plates are installed on the clamp base. All three sets of fixed brackets are rotatably installed on the clamp base. All six sets of limiting brackets are rotatably installed on the clamp base. The valve plate and brazing plate are manually assembled and placed on the graphite plates. The rotating clamping mechanism is pressed down to ensure that the valve plate can be clamped. Then, the clamping mechanism is fixed by the limiting brackets. The three sets of graphite plates facilitate the simultaneous loading of three products.

[0008] Preferably, the clamping mechanism includes an upper pressure plate and multiple sets of valve plate pressure heads. The upper pressure plate is rotatably mounted on a fixed bracket. Multiple sets of positioning holes are opened on the upper pressure plate. The valve plate pressure heads are installed in the positioning holes of the upper pressure plate. The operator installs the valve plate pressure heads into the appropriate positioning holes, and then rotates the upper pressure plate downward to make the multiple sets of valve plate pressure heads press the valve plates. Then, the upper pressure plate is fixed by the limit bracket.

[0009] Preferably, the valve plate pressure head is made of PEEK material; the valve plate pressure head made of PEEK material can effectively prevent scratches on the product surface.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the valve plate and brazing plate that are manually assembled are placed on the support mechanism, and the rotating pressing mechanism is pressed down to facilitate subsequent brazing. By setting three sets of pressing mechanisms, it is convenient to press three sets of products at the same time. Attached Figure Description

The valve plate pressure heads 22 are made of PEEK material. During operation, the valve plate and brazing plate are first manually assembled and placed on the graphite plate 12. The operator then installs the valve plate pressure heads 22 into the appropriate positioning holes, and then rotates the upper pressure plate 21 downward to press the valve plate with multiple sets of valve plate pressure heads 22.
