Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of clamps, and specifically relates to a brazing clamp. Background Technology
[0002] Brazing is a common method of joining metallic materials. It involves heating and melting a filler metal, which is then applied between the workpieces to form a strong bond. Unlike welding, brazing does not melt the materials being joined; instead, it utilizes the wettability of the filler metal to adhere it to the material surfaces, thus forming a connection. The filler metal is typically a low-melting-point alloy, such as silver, brass, or galvanized steel wire.
[0003] Brazing is typically performed in a brazing furnace. When the workpiece to be welded is not perfectly flat, it needs to be fixed in place using fixtures. However, the variety of workpieces required necessitates a variety of suitable fixtures, leading to an increase in the number of fixtures and consequently, higher production and management costs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a brazing fixture to solve the technical problem that the prior art requires a variety of tooling to match with a variety of workpieces to be welded, which leads to an increase in production and management costs.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A brazing fixture, comprising:
[0006] The clip is C-shaped, and both ends of the clip's opening are provided with through holes;
[0007] Two clamping blocks are respectively located at both ends of the opening of the clamping plate, and a stud is provided on the back of the clamping block. The stud passes through the through hole and is connected to the nut.
[0008] This invention expands the opening of the clamping piece to match the width of the opening to be welded, then uses the clamping block to keep it in close contact with the workpiece to be welded, and finally uses the elasticity of the clamping piece to fix the workpiece to be welded, thus keeping the workpiece to be welded stable.
[0009] Furthermore, the middle section of the clip has a reverse concave arc.
[0010] The beneficial effect of this step is that the reverse concave arc allows the clamp to maintain a balanced force when under tension.
[0011] Furthermore, the stud has limiting protrusions on both sides, and the distance between the two limiting protrusions is adapted to the width of the clamping piece.
[0012] The beneficial effects of this step are: the limiting protrusion ensures a stable connection between the clamping block and the clamping plate.
[0013] Furthermore, the front of the clamping block is provided with an abutment surface.
[0014] The benefits of this step are that the contact surface allows the clamping block to maintain a large contact area with the workpiece to be welded, thus maintaining clamping stability.
[0015] Furthermore, the contact surface is a plane or an arc surface.
[0016] The benefits of this step are that different shaped mating surfaces can be adapted to different shaped workpieces to be welded.
[0017] Furthermore, the material of the clip is a nickel-based high-temperature alloy, the thickness of the clip is 2±0.5mm, and the width of the clip is 10±0.5mm.
[0018] The advantages of this step are: since this brazing fixture is to be placed into the brazing furnace along with the workpiece to be welded, and the temperature inside the brazing furnace is high, in order to maintain the elasticity of the clamp itself, the clamp needs to be made of high-temperature alloy, and its mechanical properties are not affected under high temperature conditions; in addition, the specific dimensions of the clamp are designed to balance elasticity and portability.
[0019] The beneficial effects of this utility model are:
[0020] 1. The clamping piece in this application is elastic and its opening and closing degree can adapt to different sizes of workpieces to be welded. In addition, with the clamping block at the opening, it can maintain a clamping connection with the workpiece to be welded through the clamping block.
[0021] 2. The brazing fixture of this application is simple to manufacture, low in cost, convenient and flexible to use. It can be used individually or in multiples at the same time, and the position of clamping the workpiece to be welded is variable, making it highly adaptable. Attached Figure Description

[0036] Example
[0037] like Figures 1-4 As shown, the brazing fixture provided by this utility model includes:
[0038] Clip 1, the clip 1 is C-shaped, and both ends of the opening of the clip 1 are provided with through holes 11;
[0039] Two clamping blocks 2 are respectively located at both ends of the opening of the clamping plate 1, and a stud 21 is provided on the back of the clamping block 2. The stud 21 passes through the through hole 11 and is connected to the nut.
[0040] This invention expands the opening of the clamping piece 1 to match the width of the opening to be welded, then uses the clamping block 2 to keep it in close contact with the workpiece to be welded, and finally uses the elasticity of the clamping piece 1 to fix the workpiece to be welded, thus keeping the workpiece to be welded stable.
[0041] Based on the above technical solution, the middle section of the clip 1 is provided with a reverse concave arc 12.
[0042] The concave arc 12 in the opposite direction is located in the middle position, which allows the clamp 1 to maintain a balanced force when it is subjected to tension at both ends.
[0043] Based on the above technical solution, the stud 21 is provided with limiting protrusions 22 on both sides, and the distance between the two limiting protrusions 22 is adapted to the width of the clamp 1.
[0044] The limiting protrusion 22 keeps the clamping block 2 and the clamping piece 1 stably connected, so that the clamping block 2 will not rotate.
[0045] Based on the above technical solution, the front of the clamping block 2 is provided with an abutment surface 23.
[0046] The contact surface 23 allows the clamping block 2 to maintain a large contact area with the workpiece to be welded, thus maintaining clamping stability.
[0047] Based on the above technical solution, the contact surface 23 is a plane or an arc surface.
[0048] Different shaped contact surfaces 23 are adapted to workpieces of different shapes to be welded.
[0049] Based on the above technical solution, the material of the clip 1 is a nickel-based high-temperature alloy, the thickness of the clip 1 is 2±0.5mm, and the width of the clip 1 is 10±0.5mm.
[0050] Since this brazing fixture is to be placed into the brazing furnace along with the workpiece to be welded, and the temperature inside the brazing furnace is high, in order to maintain the elasticity of the clamp 1 itself, the clamp 1 needs to be made of a high-temperature alloy, and its mechanical properties are not affected under high temperature conditions; in addition, the specific dimensions of the clamp 1 take into account both elasticity and portability.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
