It can fix the spatial position during the brazing process of pipe fittings, greatly reduce the deformation amount of products, reduce the workload caused by deformation, shorten the processing time of pipe fittings, reduce the workload, and reduce the production cost of pipe fittings.

Description of the Drawings

[0017] Figure 1 is a schematic structural diagram of the present utility model. Detailed Embodiment

[0018] The present utility model will be further introduced below in conjunction with embodiments.

[0019] Please refer to Figure 1 , the present utility model discloses a slot-fixed brazing fixture. As shown in the figure: it includes a bottom plate 1 and a plurality of clamping plates. Among them:

[0020] A plurality of clamping plates are all installed in parallel on the bottom plate 1. These clamping plates at least include a first clamping plate 2 and a second clamping plate 3 with a relatively small adjacent spacing, and a third clamping plate 4 with a relatively large spacing from the adjacent clamping plates; in this embodiment, the spacing between the third clamping plate 4 and the adjacent second clamping plate 3 is relatively large, greater than the spacing between the first clamping plate 2 and the second clamping plate 3.

[0021] They are connected by a connecting rod 6 passing through each clamping plate, and the upper ends of the adjacent first clamping plate 2 and second clamping plate 3 with a relatively small spacing are also connected by a small clamping plate 5.

[0022] Each clamping plate is provided with a pipe fitting positioning groove (such as a U-shaped groove), and at least the first clamping plate 2, the second clamping plate 3, and the third clamping plate 3 are respectively provided with pipe fitting positioning grooves that are in a straight line for limiting the pipe fittings.

[0023] When the utility model is in use, the pipe fittings are placed on the pipe fitting positioning grooves in a straight line on each clamping plate. Since each clamping plate is fixed by the bottom plate 1 and is respectively strengthened and positioned and fixed by the connecting rod 6 and the small clamping plate 6, each clamping plate is stably installed and is not prone to relative displacement. During the brazing process, the spatial position of the pipe fittings is fixed by the utility model, greatly reducing the deformation amount of the product, reducing the workload caused by deformation, shortening the processing time of the pipe fittings, reducing the workload, and reducing the production cost of the pipe fittings.

[0024] In the utility model, the small clamping plate 5 is provided with at least two clamping grooves, and the upper ends of the first clamping plate 2 and the second clamping plate 3 are connected through these two clamping grooves. Or, the upper ends of the first clamping plate 2 and the second clamping plate 3 are respectively provided with clamping grooves, and the small clamping plate 5 is inserted into the clamping grooves at the upper ends of the first clamping plate 2 and the second clamping plate 3 to connect the two.

[0025] In the utility model, the lower ends of the clamping plates can be connected to the bottom plate 1 through a plugging structure. For example: the bottom plate 1 is provided with a plurality of plugging positioning holes that can be connected to the lower ends of the clamping plates, and these plugging positioning holes are arranged in an array. This increases the flexibility of use of the fixture of the utility model. During use, the positions and spacings of the clamping plates can be arranged according to the specifications of the pipe fittings. To adapt to this change, the lower end of the small clamping plate 5 can be provided with multiple clamping grooves at intervals, and any two clamping grooves can position different spacings of the first clamping plate 2 and the second clamping plate 3.

[0026] In order to increase the stability of positioning, generally two or more connecting rods 6 are arranged in parallel.

[0027] The above is only the preferred embodiment of the utility model and is not used to limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made according to the content of the scope of the patent application of the utility model should fall within the technical scope of the utility model.
