Description

Technical Field

[0001] The present application relates to the technical field of welding fixtures, and in particular to an induction brazing fixture. Background Art

[0002] With the development of industrial technology, various products have higher and higher requirements for welding quality, and more stringent requirements are put forward for the dimensional accuracy, consistency and stability of welded joints. The importance of welding workpiece fixtures as tools for achieving precision welding is becoming increasingly prominent.

[0003] Existing induction brazing fixtures have a simple structure. For example, two upwardly extending vertical blocks are provided on a base. The top of each vertical block uses a threaded clamping structure to press the workpiece against the top of the vertical block. An opening is formed between the two vertical blocks for placing an induction coil for induction brazing. However, the vertical blocks are fixedly connected to the base, and the spacing cannot be adjusted. Therefore, they are only suitable for workpieces of corresponding lengths, with a limited range of applications. The clamping structure uses a simple threaded clamping structure, which results in a limited force area on the workpiece, low clamping force, and inconvenience in manual adjustment. During the induction heating process, the solder between the mating surfaces of the workpieces melts due to the heat, causing the upper workpiece to shift downward and potentially shift forward or backward, causing skew. This requires the installation of an additional front-to-back positioning mechanism. However, the workpiece is initially subjected to a pre-clamping force, and the clamping force is maintained during the welding process. Therefore, after the solder melts, it does not move forward or backward. In this case, the front-to-back positioning mechanism will interfere with wider workpieces, making this fixture unsuitable for wider workpieces.

[0004] Therefore, it is necessary to design an induction brazing fixture to solve the above problems. Utility Model Content

[0028] According to the induction brazing fixture provided by the utility model, Figures 1 to 4 As shown, the induction brazing fixture is used for brazing operations, and the induction brazing fixture includes a base 1 and a supporting clamping mechanism.

[0029] In the following description, reference will be made to Figures 1 to 4 The detailed structures of the base 1 and the supporting clamping mechanism of the induction brazing fixture are described in detail.

[0030] like Figures 1 to 3 As shown, in an embodiment, the support and clamping mechanism may include a first support and clamping assembly 2 and a second support and clamping assembly 3 spaced apart from each other, and the first support and clamping assembly 2 and the second support and clamping assembly 3 may respectively support and clamp the two ends of the workpiece 6 to be welded, so that the induction brazing fixture cooperates with the workpiece 6 to perform brazing operations. The distance set between the first support and clamping assembly 2 and the second support and clamping assembly 3 can be used for the layout of the induction coil 10, and is also convenient for the installation of workpieces of different lengths. The first support and clamping assembly 2 and the second support and clamping assembly 3 can both be used as modular components, which are easy to install and disassemble, can ensure accuracy, and are easy to repair and replace, with low cost, and are convenient for clamping the workpiece 6.

[0031] Specifically, the first support and clamping assembly 2 and the second support and clamping assembly 3 can each include a support portion 4 and an adjustable clamping portion, wherein a first end of the support portion 4 is movably connected to the base 1, and a second end of the support portion 4 is connected to the adjustable clamping portion. The first support and clamping assembly 2 and the second support and clamping assembly 3 can both change their positions on the base 1 through the support portion 4, thereby adjusting the distance between the first support and clamping assembly 2 and the second support and clamping assembly 3 to accommodate workpieces 6 of different lengths.

[0032] Furthermore, the adjustment clamping portion may include a clamping body 501, a fixing member 502 and an adjustment member. The clamping body 501 is provided with a clamping position, and the workpiece 6 can be clamped at the clamping position. The fixing member 502 is provided at the clamping position, and the fixing member 502 can be understood as the lower end of the clamping position. The workpiece 6 is placed on the fixing member 502, and one end face of the workpiece 6 can abut the fixing member 502 of the clamping position. The adjustment member is provided on the upper part of the fixing member 502, and the adjustment member is movably provided on the clamping body 501. When it is necessary to clamp the workpiece 6, the position of the adjustment member can be changed so that the adjustment member is close to the fixing member 502 and abuts against the other end face of the workpiece 6 to achieve clamping. In addition, the opening direction of the clamping position is staggered with the moving direction of the first support clamping assembly 2 and the second support clamping assembly 3, which is convenient for sampling and layout.

[0033] In this way, the induction brazing fixture, through the cooperation between the base 1 and the support clamping mechanism, enables the first support clamping component 2 and the second support clamping component 3 of the support clamping mechanism to be adjusted and arranged on the base 1, and then adjusts the distance between the first support clamping component 2 and the second support clamping component 3 to adapt to workpieces of different lengths, so that the induction brazing fixture can be used for workpieces 6 of different specifications, with a wide range of applications and simple and easy adjustment. The modular design of the first support clamping component 2 and the second support clamping component 3 can effectively reduce processing costs and achieve high precision. The workpiece 6 can be clamped quickly and easily by adjusting the clamping part. At the same time, due to the cooperation between the fixing part 502 and the adjusting component, the clamping area is large during the process of clamping the workpiece 6, and the workpiece 6 can be clamped comprehensively and fully, so that the clamping force is large and the clamping is stable, which is also easy to adjust. In addition, since the adjustment clamping part of the first support clamping component 2 and the adjustment clamping part of the second support clamping component 3 can be adjusted separately, the brazing seam thickness can be controlled.

The induction coil 10 is arranged at the position where the solder is located to facilitate induction brazing. Since the first division 601 and the second division 602 can be respectively arranged at the adjustment clamping portion of the first support clamping assembly 2 and the adjustment clamping portion of the second support clamping assembly 3, the thickness of the brazing seam at the connection between the first division 601 and the second division 602 can be controlled by adjusting the positions of the clamped first division 601 and the clamped second division 602.

[0036] Preferably, if Figures 1 to 4 As shown, in an embodiment, the second end of the support portion 4 is detachably connected to the adjustment clamping portion via a connecting plate 8. Specifically, in an embodiment, the support portion 4 and the adjustment clamping portion can both be formed into modular block structures, and the two block structures can be connected via a connecting plate 8. Connecting screws are provided at both ends of the connecting plate 8, and the two ends of the connecting plate 8 can be connected to the support portion 4 and the adjustment clamping portion, respectively, to achieve fixation of the two. The detachably connected support portion 4 and the adjustment clamping portion can meet modular requirements and further increase the accuracy of use of the two. At the same time, adjustment clamping portions of different specifications can be replaced as needed to further adapt to workpieces 6 of different specifications, and have a wide range of uses.

[0037] Preferably, in another embodiment, the support portion 4 and the adjustable clamping portion can also be integrally formed. This integrally formed support portion 4 and adjustable clamping portion facilitates installation, replacement, and maintenance, and eliminates the need for a connecting plate 8, thereby reducing the number of parts.

In this way, the user can install the first supporting and clamping assembly 2 and the second supporting and clamping assembly 3 in different positions to adapt to workpieces 6 of different shapes to meet clamping requirements.

[0040] Preferably, if Figures 1 to 4 As shown, in this embodiment, the adjustment member may include an active adjustment member 503, an adjustment link 504, and an adjustment block 505.

The user can adjust the adjustment link 504 through the active adjustment member 503 to drive the adjustment block 505 to move, thereby achieving clamping of the workpiece 6.

[0041] Preferably, in another embodiment, if a shim is not used to adjust the height of the workpiece 6, a lifting member (not shown) may be provided, and both the first support and clamping assembly 2 and the second support and clamping assembly 3 may be provided with a lifting member, and the support portion 4 may be provided on the base 1 with adjustable height via the lifting member. Specifically, the lifting member may be a screw guide or a vertical motion cylinder, and the position of the clamping position is adjusted by the lifting member, thereby changing the relative position of the first subsection 601 and the second subsection 602 to enable subsequent brazing operations.

[0042] Preferably, if Figures 1 to 3 As shown, in the embodiment, the first moving member 901 is formed as a slide groove embedded with a nut member, and the second moving member 902 is provided with a connecting hole, which is connected to the nut member via a screw member.

[0045] Preferably, if Figures 1 to 3 As shown, in the embodiment, the active adjustment member 503 is formed as a rotating handle, and the adjustment link 504 and the adjustment block 505 are formed as a screw nut structure. By rotating the rotating handle, the adjustment link 504 is driven to rotate, thereby driving the adjustment block 505 to move closer to or away from the fixing member 502.

[0046] Preferably, in another embodiment, the active adjustment member 503 can also be formed as a cylinder, the adjustment connecting rod 504 is formed as a telescopic rod, and the adjustment block 505 is connected to the cylinder through the telescopic rod. The adjustment block 505 is driven by the cylinder to move closer to or away from the fixing member 502 to achieve clamping of the workpiece 6.

[0047] Preferably, if Figure 4 As shown, in this embodiment, a typical workpiece 6 can be two long, overlapping members, with solder placed between the overlapping surfaces. The solder melts to form a brazed seam. Specifically, a weld is formed between the first section 601 and the second section 602. The solder is placed in the weld, and the weld has a thickness of H. The thickness of the first section 601 and the thickness of the second section 602 are both H1.

[0048] The shim set may include a first shim 701 with a thickness of h1, a second shim 702 with a thickness of h2, a third shim with a thickness of h3, ..., and the like. n The nth gasket (in the embodiment, two gaskets, namely the first gasket 701 and the second gasket 702 are taken as an example). The first gasket 701, the second gasket 702, ..., the nth gasket are sequentially arranged between the fixing member 502 and the lower end surface of the first sub-portion 601.

[0049] exist Figure 4 In the embodiment, the thickness of the first gasket 701 needs to be the same as the thickness of the second sub-portion 602 to meet the requirement of padding the first sub-portion 601, that is, h1=H1.

[0050] Further, in Figure 4 The thickness of the weld can be the same as the thickness of the second gasket 702. If more gaskets are used, then h2+h3+...+h n =H.

[0051] The process of using the induction brazing fixture is as follows: first, the positions of the first supporting clamping assembly 2 and the second supporting clamping assembly 3 are adjusted by the first movable member 901 and the second movable member 902 so that the distance between the two can meet the clamping requirements of the workpiece 6. Then, the first subsection 601 of the workpiece 6 is placed in the clamping position of the first supporting clamping assembly 2, and the second subsection 602 of the workpiece 6 is placed in the clamping position of the second supporting clamping assembly 3. In the embodiment, when the first subsection 601 is placed, a shim group is provided between the first subsection 601 and the fixing member 502. The placement of the shim group and the thickness of the weld meet the above-mentioned h2+h3+…+h n =H, and also ensure the parallel overlap of the workpiece 6. Then adjust the clamping portion so that the adjusting member and the fixing member 502 can clamp the workpiece 6. After the adjustment is completed, the brazing operation can be carried out.

[0052] The induction brazing fixture cooperates with the base and the support clamping mechanism so that the first support clamping assembly and the second support clamping assembly of the support clamping mechanism can be adjusted to be arranged on the base, and then the distance between the first support clamping assembly and the second support clamping assembly can be adjusted to adapt to workpieces of different lengths, so that the induction brazing fixture can be used for workpieces of different specifications, with a wide range of applications and simple and easy adjustment. The modular design of the first support clamping assembly and the second support clamping assembly can effectively reduce processing costs and achieve high precision. The workpiece can be clamped quickly and easily by adjusting the clamping part. At the same time, due to the cooperation between the fixing part and the adjusting component, the clamping area is large during the process of clamping the workpiece, and the workpiece can be clamped comprehensively and fully, so that the clamping force is large and the clamping is stable, which is also easy to adjust. In addition, since the adjustment clamping part of the first support clamping assembly and the adjustment clamping part of the second support clamping assembly can be adjusted separately, the brazing seam thickness can be controlled.
