Description

Technical Field

[0001] The utility model relates to the technical field of diffusion welding, in particular to a double-station soft-connection diffusion welding cooling fixture. Background Art

[0002] At present, conventional diffusion welding rarely uses welding jigs and is mostly manual operation. However, for products with high requirements, high stability needs to be maintained during the production process, so strict control of product dimensions is required. In this case, diffusion welding jigs are needed to ensure product stability. Since the temperature of diffusion welding is 600-750℃, cooling jigs are required for welded products at high temperatures to ensure product functionality.

[0003] The reason why diffusion welding requires cooling jigs is that: (1) Since the welding jigs will maintain a certain high temperature when the production line is working for a long time, they need to be frequently placed in water to cool down. At this time, multiple sets of jigs need to be replaced to meet the continuous production, which will increase the jig cost and labor cost. In addition, when the jig is at high temperature, it will be dangerous for workers to operate it, which poses a safety problem. (2) Since copper is easily oxidized when it comes into contact with air at high temperatures, cooling water is directly applied to the product during welding to stabilize the performance of the product. However, due to factors such as the instability of the water flow and the position of the water pipe, workers need to constantly adjust the cooling water application point, which not only increases the workload of the workers, but also causes instability in product quality. (3) In the existing method, since the cooling water acts on the product during welding, the water will inevitably affect the welding electrode (graphite). The electrode will also accelerate oxidation due to contact with water, thereby affecting the welding life and efficiency. Utility Model Content

[0007] Preferably, the positioning fixture is fixedly mounted on a positioning fixture fixing plate;

[0008] The lifting mechanism is fixedly mounted on a lifting mechanism fixing plate;

[0009] The upper part of the lifting mechanism is connected to the positioning fixture fixing plate.

[0010] Preferably, the positioning fixture comprises an upper pressing plate and a lower supporting plate, and the lower supporting plate is provided with a product placement groove.

[0011] Preferably, a cooling water inlet and outlet are provided on the positioning fixture, and the cooling water inlet and outlet are connected to the cooling water channel.

[0012] Preferably, the lifting mechanism is a screw-driven lifting platform, and the screw-driven lifting platform is a cross-type structure.

[0017] The beneficial effects of the utility model are:

[0018] (1) The utility model discloses a double-station soft-connect diffusion welding cooling fixture, which adopts a welding fixture plus a cooling water circulation cooling method inside the fixture. The positioning fixture makes the position of the workpiece to be welded more stable.

[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be better understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0028] Example:

[0029] This embodiment introduces the structure of a dual-station soft-connect diffusion welding cooling fixture.

[0030] As attached Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a dual-station soft-connect diffusion welding cooling fixture of the utility model.

[0031] A dual-station soft connection diffusion welding cooling fixture, comprising: a positioning fixture 1, a lifting mechanism 2, wherein the positioning fixture 1 is located above the lifting mechanism 2;

[0032] A cooling water channel is provided in the positioning fixture 1 .

[0033] Furthermore, the positioning fixture 1 is fixedly mounted on the positioning fixture fixing plate 1-1;

[0034] The lifting mechanism 2 is fixedly mounted on the lifting mechanism fixing plate 2-1;

[0035] The upper 2 sides of the lifting mechanism are connected to the positioning fixture fixing plate 1 - 1 .

[0036] The fixing plates are connected together, making the installation between the structures more stable, thereby improving the welding accuracy.

[0037] like Figure 2 As shown, Figure 2 It is a partial structural diagram of a dual-station soft connection diffusion welding cooling fixture. The positioning fixture 1 includes an upper pressing plate 1-2 and a lower bearing plate 1-3, and the lower bearing plate 1-3 is provided with a product placement groove 1-4. When the product is placed in the product placement groove, the upper pressing plate and the lower bearing plate are tightly connected, and the product workpiece is tightly pressed therein, which improves the stability and accuracy of the workpiece position fixation and avoids the deviation and shaking of the workpiece during welding.

[0038] In this embodiment, the positioning fixtures 1 are provided in two groups.

[0039] Furthermore, the positioning fixture 2 is provided with a cooling water inlet and outlet 4, and the cooling water inlet and outlet 4 is connected to the cooling water channel. The cooling water inlet and outlet facilitate the entry and exit of cold water, and the cooling water flows in the cooling water channel with a stable water flow, thereby realizing the circulating cooling and temperature reduction function of the welding product, and reducing the risk of workers being scalded during the welding process. Moreover, the implementation of this structural design does not require workers to repeatedly adjust the position of the water pipe to adjust the point of action of the cooling water like in the original method. After the fixture is installed, the workers can stay away from the welding electrodes, which greatly improves safety and reduces workload. In addition, the cooling water flows in the cooling water channel, flows in and out of the cooling water inlet and outlet, reduces the degree of water splashing, and thus greatly avoids the influence of water on the welding electrodes.

[0040] Furthermore, the lifting mechanism 2 uses a screw-driven lifting platform, which has a relatively simple structure, fewer faults, and low maintenance costs. It is easy to achieve precise control of the lifting speed and stroke, and has the characteristics of high precision and good stability. In addition, the lifting mechanism 2 uses a cross-type structure, which can achieve a 60mm up and down displacement, and can adapt to more products, thereby ensuring that the product to be welded in the positioning fixture is flush with the welding motor.

[0041] After the product is placed in the positioning fixture, the lifting mechanism is adjusted so that the product to be welded in the positioning fixture is flush with the welding motor, ensuring accurate docking of the welding parts, reducing defective products caused by welding deviations and defects, and making the mass-produced welded parts have high consistency and stability.

[0042] like Figure 3 , 4 As shown, Figure 3 This is a schematic diagram of the structure of a dual-station soft connection diffusion welding cooling fixture from another angle. Figure 4The figure is a schematic diagram of a double-station soft connection diffusion welding cooling fixture. The double-station soft connection diffusion welding cooling fixture includes a rotary cylinder 3 that drives the positioning fixture 1 and the lifting mechanism 2 to rotate; the rotary cylinder 3 is located below the lifting mechanism 2 and is fixedly mounted on a cylinder fixing plate 3-1; the top of the rotary cylinder 3 is connected to the lifting mechanism fixing plate 2-1.

[0043] By adding a rotating cylinder, the welded product can be quickly turned to the operator through the rotating cylinder, so that the worker can quickly take out the welding workpiece and put the workpiece to be welded into the positioning fixture to carry out the next welding operation.

[0044] In this embodiment, the use of the cooling fixture is briefly described. The operator places the product to be welded on the positioning fixture 1, and cooling water circulates inside the positioning fixture 1 to cool it down. After fixing the product to be welded, adjust the lifting mechanism 2 so that the product to be welded is flush with the welding electrode and corresponds to the welding position; start the diffusion welding machine to start welding, and after welding is completed, start the switch, and the rotating cylinder 3 rotates to turn the welded product to the operator. The worker takes out the welded parts and puts in new parts to be welded. Repeat the above actions to complete mass production.

[0045] In addition, the cooling fixture can be adjusted according to the specifications of the welding machine and graphite, and other types of products can be processed by replacing the product clamping part.

[0046] The dual-station soft-connection diffusion welding cooling fixture introduced in this embodiment uses a welding fixture plus cooling water circulation cooling inside the fixture to achieve cooling treatment of the product being welded, and adds a rotating cylinder and a height adjustment device to the fixture base, which can achieve fast loading and unloading, and can be adapted to multiple types of products. This utility model solution can greatly improve the production efficiency of diffusion welding, reduce the defective rate of products, and easily realize automated production, thereby reducing production costs.

[0047] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
